Abstract
The utility model discloses a kind of sampling glass tube sampling servicing unit, comprise rubber tube, casing drive head and sleeve pipe, the outer wall of described sampling glass tube is set with a sleeve pipe, the head of sampling glass tube is connected with rubber tube by casing drive head, and the leading portion of described casing drive head coordinates with rubber tube inwall, the stage casing of casing drive head and sampling pipe head fits, the back segment of casing drive head coordinates with the outer wall of sleeve pipe.The utility model, by the connection of casing drive head, solves 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.
Description
Technical field
The utility model relates to the field using sampling glass tube, particularly relates to a kind of device auxiliary for sampling glass tube sampling.
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.
Utility model content
The purpose of this utility model 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 utility model adopts following technical scheme:
A kind of sampling glass tube sampling servicing unit, comprise rubber tube, casing drive head and sleeve pipe, described casing pipe sleeve is contained on the outer wall of sampling glass tube, the head of sampling glass tube is connected with rubber tube by casing drive head, and the leading portion of described casing drive head coordinates with rubber tube inwall, the stage casing of casing drive head and sampling glass tube head fits, the back segment of casing drive head 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 being connected with casing drive head inside thread; Thereafter segment trailer is wire gauze, and mesh diameter is less than sampling glass tube external diameter, for installing rear pressed glass sampling pipe.
Described casing drive head is an inner hollow, 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 of sampling pipe and casing drive head; Back segment is hollow cylindrical, coordinates with the outer wall of sleeve pipe.
The leading portion external diameter of described casing drive head 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 of described casing drive head coordinates with the rubber blanket being arranged on sampling glass tube head.
The back segment of described casing drive head is provided with internal thread, coordinates with the external thread being arranged on sleeve pipe leading portion.
The beneficial effects of the utility model are: by the connection of casing drive head, 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, hand can not be hindered, can not drop during sampling, also can not scratch and be sampled people.
Accompanying drawing explanation
Fig. 1 is the utility model device diagrammatic cross-section.
In figure: 1-rubber tube; 2-casing drive head; 3-sleeve pipe; 4-sampling glass tube; 5-casing drive head leading portion is protruding; 6-rubber blanket; 7-wire gauze.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1: sampling glass tube sampling servicing unit comprises rubber tube 1, casing drive head 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 is connected with rubber tube 1 by casing drive head 2, and the leading portion of described casing drive head 2 coordinates with rubber tube 1 inwall, the stage casing of casing drive head 2 and sampling pipe 4 head fits, the back segment of casing drive head 2 coordinates 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 casing drive head 2 hollow, 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 of sampling pipe and casing drive head.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.
