Abstract
The invention discloses a sampling aid for a glass sampling tube and an application method thereof. The sampling aid comprises a rubber tube, a casing cap and a casing. The outer wall of the glass sampling tube is sleeved with the casing; the head of the glass sampling tube is connected with the rubber tube through the casing cap; the front of the casing cap fits the inner wall of the rubber tube; the middle of the casing cap fits the head of the glass sampling tube; the rear of the casing cap fits the outer wall of the casing. By the connection via the casing cap, the problem that the same rubber tube is difficult to connect with an air sampling pump and the glass sampling tube; operating is simple, putting the glass sampling tube into the casing is just required before tightening, and no hand injury is caused; during sampling the sampling aid never falls or scratches a sampler.
Description
Technical field
The present invention relates to the field using sampling glass tube, particularly relate to a kind of device auxiliary for sampling glass tube sampling and using method.
Background technology
Prior art often uses activated charcoal sampling pipe or silica gel sampling pipe when gathering noxious material in air, these sampling pipes are glass tube, during use, disconnected pipe is carried out to sampling pipe two ends, be connected to air sampling pump by rubber tube, be put in and be sampled people's breathing zone position and sample.Its operation has following defect:
1, air sampling pump steam inlet external diameter is generally large than sampling glass tube mouth of pipe external diameter, and can cause air sampling pump steam inlet junction tension when rubber tube connects, not easily connect, sampling glass tube junction is excessively loose, easily drops in sampling pipe sampling process.
When 2, rubber tube being inserted in sampling glass tube one end, easily scratch hand, pine or tension all affect sampling excessively.Cross pine, during sampling, sampling pipe easily drops; Tension, sampling pipe is difficult to insert, and wastes time and energy.
3, during sampling, the glass tube that one end disconnects is exposed in outside, easily scratches and is sampled personnel.
Summary of the invention
Object of the present invention be exactly in order to solve prior art exist the problems referred to above and deficiency, provide a kind of sampling glass tube sample servicing unit, facilitate sampling pipe to be connected with air sampling pump, protect sample collector.
To achieve these goals, the present invention adopts following technical scheme:
A kind of sampling glass tube sampling servicing unit, comprise rubber tube, sleeve pipe emits and sleeve pipe, described casing pipe sleeve is contained on the outer wall of sampling glass tube, the head of sampling glass tube is emitted by sleeve pipe and is connected with rubber tube, and the leading portion that described sleeve pipe emits coordinates with rubber tube inwall, the stage casing that sleeve pipe emits and sampling glass tube head fits, the back segment that sleeve pipe emits coordinates with the outer wall of sleeve pipe.
The head of described rubber tube is connected with air sampling pump, and its length is 90cm.
Described sleeve pipe is hollow cylindrical, has external thread outside its leading portion, for emitting inside thread to be connected with sleeve pipe; Thereafter segment trailer is wire gauze, and mesh diameter is less than sampling glass tube external diameter, for installing rear pressed glass sampling pipe.
It is an inner hollow that described sleeve pipe emits, and comprises leading portion, stage casing and back segment 3 parts; Its leading portion is hollow cylindrical, coordinates with the inwall of rubber tube; Stage casing is hollow conic, for sealing the contact site that sampling pipe and sleeve pipe emit; Back segment is hollow cylindrical, coordinates with the outer wall of sleeve pipe.
The leading portion external diameter that described sleeve pipe emits is less than rubber tube internal diameter, and is provided with projection at its outer wall, and convenient and rubber tube junction seals.
The inner side in the stage casing that described sleeve pipe emits coordinates with the rubber blanket being arranged on sampling glass tube head.
The back segment that described sleeve pipe emits is provided with internal thread, coordinates with the external thread being arranged on sleeve pipe leading portion.
The using method of said apparatus is as follows:
Leading portion is emitted by sleeve pipe to insert in rubber tube, sleeve pipe emits leading portion projection to be sealed junction, sampling glass tube is put into sleeve pipe, sleeve pipe leading portion is put into sleeve pipe and is emitted back segment, tighten, sampling glass tube outlet side to be pressed in during sleeve pipe emits by wire gauze by sleeve pipe, the contact position that sleeve pipe emits the rubber seal sampling glass tube in stage casing and sleeve pipe to emit, connection completes, and the rubber tube other end is received on air sampling pump and sampled.
The invention has the beneficial effects as follows: the connection of being emitted by sleeve pipe, solve the problem that same rubber tube is not easily connected with air sampling pump and sampling glass tube, easy and simple to handle, sampling glass tube is put into sleeve pipe tighten, can not hand be hindered, can not drop during sampling, also can not scratch and be sampled people.
Accompanying drawing explanation
Fig. 1 is apparatus of the present invention diagrammatic cross-section.
In figure: 1-rubber tube; 2-sleeve pipe emits; 3-sleeve pipe; 4-sampling glass tube; 5-sleeve pipe emits leading portion protruding; 6-rubber blanket; 7-wire gauze.
Embodiment
Below in conjunction with drawings and Examples, the present invention will be further described.
As shown in Figure 1: sampling glass tube sampling servicing unit comprises rubber tube 1, sleeve pipe emits 2, sleeve pipe 3 and sampling glass tube 4, the outer wall of described sampling glass tube 4 is set with a sleeve pipe 3, the head of sampling glass tube 4 emits 2 to be connected with rubber tube 1 by sleeve pipe, and described sleeve pipe emits the leading portion of 2 to coordinate with rubber tube 1 inwall, sleeve pipe emits stage casing and sampling pipe 4 head fits of 2, and sleeve pipe emits the back segment of 2 to coordinate with the outer wall of sleeve pipe 3.
Described rubber tube 1 conveniently can connect the rubber tube of air sampling pump for caliber, and length is about 90cm.
Described sleeve pipe emits 2 hollows, adopts hard material (metal or duroplasts), comprises leading portion, stage casing and back segment 3 parts.Leading portion is hollow cylindrical, and external diameter is slightly less than rubber tube internal diameter, and there is projection in outside, and convenient and rubber tube junction seals.Interrupt for hollow conic, inner side is adherent rubber blanket, for sealing the contact site that sampling pipe and sleeve pipe emit.Back segment is the hollow cylindrical that caliber is larger, and there is screw thread inner side, is about 3cm, facilitates the fixing of the sampling glass tube of different length.
