Abstract
The invention relates to a lockset mechanism controlled by a solenoid valve, comprising a lock body, a solenoid valve, a shaft sleeve, a brake shaft, a brake spring, a circular screw nut and a lock catch; wherein, the solenoid valve is arranged in the intracavity of the case of lock; the shaft sleeve is arranged on one end of the lock body, and communicated with the intracavity of the lock body; the brake shaft can be positioned in the shaft sleeve; the shaft sleeve is sealed and covered by the circular screw cap and the lock catch; the lockset mechanism is characterized in that the brake spring comprises the parent spring and the subsidiary spring, wherein the two springs are stringed and sleeved together in reversed spin enwinding, and the diameters of the two springs are different. The parent spring and the subsidiary spring are made of one same spring wire; the length of the subsidiary spring is shorter than that of the parent spring. The prior single brake spring is replaced by the forward-reversed spin parent-subsidiary springs which are stringed and sleeved together, which not only retains the using function of original brake spring, but also effectively overcomes the unlocking mispoeration due to the resonance produced by the outside vibration and impact of single brake spring; the lockset mechanism controlled by a solenoid valve provides the technical support for eliminating the potential hazard of the lockset.
Description
Technical field
The present invention relates to a kind of locking mechanism, especially a kind of magnetic valve controlled locking mechanism belongs to lockset kind.
Background technology
As shown in Figure 6 be a kind of known magnetic valve controlled lockset, by lock body 1, be located at the lock body inner chamber electromagnetic valve 7, be located at lock body one end and the axle sleeve 2 that communicates with the lock body inner chamber, can place the round nut 5 and the snap close 6 of brake axle 3, tripping spring 4 and capping axle sleeve in the axle sleeve to form.It makes brake axle 3, the tripping spring of being located in lock body 1 axle sleeve 2 ante-chambers 4 by the break-make of electromagnetic valve, and the relative motion of push rod that places the electromagnetic valve 7 of axle sleeve back cavity (or lock body in), make the brake axle 3 that is in the axle sleeve realize displacement, and under the cooperation of being located at the snap close 6 on the lock body 1, realize the opening and closing of lockset.Promptly under the state that does not have electricity because the effect of tripping spring 4 makes brake axle 3 move right along the inner chamber of axle sleeve 2, under the cooperation of snap close 6, make lockset be in blocking; In case and electromagnetic valve 7 must conduct, because therefore stretching out of the push rod of this electromagnetic valve make the brake axle 3 in the axle sleeve 2 oppress tripping springs 4 contractions and to left dislocation, make lockset be in opening.This lockset simple in structure because structure is very simple, opens, cuts out also very convenient, so it has been one of preferred lockset of all kinds of doors and cabinet.
But, find also that in utilization there is certain drawback in it, because it mainly is to reach the purpose of impelling the brake axle displacement by the contraction of tripping spring and the elongation that resets, therefore when this tripping spring was subjected to a certain certain vibration frequency impact, tripping spring also can produce contraction.Obviously this will give and use the user of this kind lockset to bring potential safety hazard.
Therefore, how to overcome because the lockset potential safety hazard that tripping spring may bring because of the misoperation that resonance produces is further improved problem to be solved with regard to becoming such lockset.
Summary of the invention
Purpose of the present invention: be intended to propose a kind of magnetic valve controlled lockset, both kept the existing magnetic valve controlled simple structure that lockset had, have reliable safe application performance simultaneously again with firm service behaviour.
This magnetic valve controlled locking mechanism, by lock body 1, be located at the lock body inner chamber electromagnetic valve 7, be located at lock body one end and the axle sleeve 2 that communicates with the lock body inner chamber, can place the round nut 5 and the snap close 6 of brake axle 3, tripping spring 4 and capping axle sleeve in the axle sleeve to form, it is characterized in that: two the diameter differences that described tripping spring 4 is nested together by string and the female spring 4-1 and the sub-spring 4-2 of derotation coiling each other constitute.Be that described primary and secondary spring one is the dextrorotation spring, another is a left-handed spring.
Described female spring 4-1 and sub-spring 4-2 are made by same spring steel wire.
The length of described sub-spring 4-2 should be less than female spring 4-1.
Described primary and secondary spring by two independently the spring steel wire coiling form.
This magnetic valve controlled locking mechanism according to above technical scheme proposition, owing to two strings are nested together and the primary and secondary spring of derotation each other replaces existing single tripping spring, the function of use that has not only still kept original tripping spring, and can very overcome single tripping spring effectively and be subjected to may producing resonance when extraneous vibration impacts, thereby cause open by mistake the lock action; Therefore provide technical support for the potential safety hazard of eliminating such lockset.

The specific embodiment
This magnetic valve controlled locking mechanism shown in Fig. 1-5, it is a kind of inventive improvements to existing congenerous lockset, this magnetic valve controlled lockset, by lock body 1, be located at the lock body inner chamber electromagnetic valve 7, be located at lock body one end and the axle sleeve 2 that communicates with the lock body inner chamber, can place the round nut 5 and the snap close 6 of brake axle 3, tripping spring 4 and capping axle sleeve in the axle sleeve to form, it is characterized in that: two the diameter differences that described tripping spring 4 is nested together by string and the female spring 4-1 and the sub-spring 4-2 of derotation coiling each other constitute; Be that described primary and secondary spring one is the dextrorotation spring, another is a left-handed spring.
Described female spring 4-1 and sub-spring 4-2 are made by same spring steel wire.
The length of described sub-spring 4-2 should be less than female spring 4-1.
Described primary and secondary spring by two independently the spring steel wire coiling form.
The principle of its use is as follows: when normal operating condition because the effect of primary and secondary spring, brake axle in the axle sleeve makes lock body be in blocking under the cooperation of snap close, in case electromagnetic valve gets, because the jacking effect of stretching out push rod of electromagnetic valve, compression primary and secondary spring, make brake axle break away from the blocking effect of snap close, this moment, lockset was in opening.Above-mentioned unlatching and locking duty and existing congenerous lockset are just the same.But in case when being subjected to improper impacts, because the vibration frequency of primary and secondary spring is different fully, the frequency of the female spring in instant extraneous vibration frequency of impact and the primary and secondary spring is close, and female spring is compressed, and causes the micro-displacement of brake axle generation.But the sub-spring in the primary and secondary spring is because the form of its coiling is just in time opposite with the coiling form of female spring, can not produce same frequency resonance under same vibration source condition; Therefore can not cause sub-spring to compress simultaneously.So can guarantee that finally this lockset still is in blocking.Simultaneously, owing to adopt two opposite each other rotary-type springs to form the shrapnel spring, the intersection each other in also can effectively avoiding between the outer spring, wrapping phenomena produce.
In actual applications, above-mentioned primary and secondary spring also can adopt two independently, the spring string of diameter difference derotation each other is nested together and forms the primary and secondary spring, this moment is as long as the independent same axle center be fixed on two springs on the axle sleeve blind nut respectively.
