Description

A kind of gas chromatographic sample introduction syringe needle straightener

Technical field

A kind of environment measuring analysis technical field is the utility model is related to, more particularly to a kind of gas chromatographic sample introduction syringe needle is adjusted Straight device.

Background technology

Gas chromatographic sample introduction pin will often be used by being tested in laboratory, but in use, often be occurred various Situation curves gas chromatographic sample introduction syringe needle the situation of song：

1. injection port is twisted too tight, at room temperature the stubborn too tightly meeting after the expansion of silica gel sealing pad when temperature of vaporization chamber raises Tighter, at this moment syringe is difficult that bundle is entered；

2. position looks for bad pin to prick at injection port metal position；

3. overexerting causes；In order to save experimental article, agree with the target of China's energy-saving and emission-reduction, develop economy Virtue, directly the syringe needle of bending is lost and does not meet our style clearly, also increases experimental cost.

The content of the invention

Adjusted in view of the deficienciess of the prior art, the purpose of this utility model aims to provide a kind of gas chromatographic sample introduction syringe needle Straight device.It is compared to directly losing in reality or multiple with retouching merely without using instrument, the utility model have it is simple in construction, The characteristics of easy to use, it only need to adjust positive plate with worm gearing and clamp the syringe needle of bending, after pulling and pushing repeatedly several times just The purpose of preliminary correction syringe needle can be reached.If be unsatisfied with to straightening effect, the groove from smaller diameter is can also continue to, Straightening can be completed by repeating the above steps.

In order to realize above-mentioned technique effect, the utility model provides a kind of gas chromatographic sample introduction syringe needle straightener, bag A handle, cloudy plate and positive plate are included, the cloudy plate is fixed on handle front end side, and the positive plate movable type is arranged at described Handle front end opposite side, a worm gearing is provided between described positive plate and handle；Have two on positive plate described in projection The cuboid that individual above size is successively decreased is raised, and described cloudy plate is provided with and the raised corresponding length of the cuboid on the positive plate The cuboid is raised after cube groove, cloudy plate and positive plate closing and cuboid groove can just agree with, and the cuboid is convex Rise and cuboid groove is set with handle vertical direction；The size of cuboid groove in the cloudy plate is one times of pin external diameter To three times.

Preferably, the number of the cuboid groove on described cloudy plate is two to four.

Preferably, the number of the cuboid projection on described positive plate is two to four.

Preferably, described handle is hollow structure.

Preferably, described cloudy plate and positive plate are rectangle structure.

Preferably, there is anti-slip rubber piece on described handle.

Compared with prior art, it is difficult to solve the problems, such as that the bending of gas chromatographic sample introduction syringe needle is repaired afterwards for the utility model. Simple in construction, easy to use, a people can be rapidly completed operation；The design of worm gearing so that positive plate can move While, the holding of clamping effect can be ensured again, can not have to need manpower to protect as clamp type structure after clamping Clamping is held, hand is vacated and pulls out to take out etc. completing syringe needle and act in next step.

Brief description of the drawings

The utility model is described in further detail with reference to the accompanying drawings and examples.Wherein：

Fig. 1 is a kind of structural representation of gas chromatographic sample introduction syringe needle straightener；

Fig. 2 is a kind of side view of gas chromatographic sample introduction syringe needle straightener；

In figure：1st, positive plate；2nd, cloudy plate；3rd, cuboid groove；4th, cuboid is raised；5th, worm gearing；6th, handle；7、 Anti-slip rubber piece.

Embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model Define.

Fig. 1 and Fig. 2 illustrates a kind of gas chromatographic sample introduction syringe needle straightener, including a handle 6, cloudy plate 2 and positive plate 1, The cloudy plate 2 is fixed on the front end side of handle 6, and the positive movable type of plate 1 is arranged at the front end opposite side of handle 6, institute A worm gearing 5 is provided between the positive plate 1 and handle 6 stated, worm gearing 5 is with reference to the transmission in monkey wrench Structure design；Have the cuboid projection 4 that two or more size is successively decreased on described positive plate 1, described cloudy plate 2 be provided with it is described The raised 4 corresponding cuboid grooves 3 of cuboid on positive plate 1, cloudy plate 2 and positive plate 1 the cuboid projection 4 and length after closing Cube groove 3 can just agree with, and the number of cuboid groove 3 and cuboid projection 4 is two, rectangular in the cloudy plate 2 The size of body groove 3 is one times to three times of pin external diameter.

Generally, the number of cuboid groove 3 and cuboid projection 4 is two to four, and cloudy plate 2 and positive plate 1 are Rectangle structure, ensure to save production cost while using effect；Handle 6 is hollow structure, alleviates the weight of this product, Improve the real experiences of user, convenient use；Handle is provided with anti-slip rubber piece 7, can improve operating efficiency and ensure to make With safety.

In actual use, first with from maximum cuboid groove 3, positive plate 1 is adjusted to using worm gearing 5 Suitable position, then the syringe needle of bending is inserted, then adjust positive plate 1 with worm gearing 5 and be tightly bonded with cloudy plate 2, then instead Pulling and pushing again makes syringe needle straightening；If be unsatisfied with the effect of modulation, can be further continued for continuing weight from smaller cuboid groove 3 Multiple above-mentioned steps carry out straightening work.
