In the figure: 1. a base; 2. a sampling tank; 3. sealing the tank plug; 4. a sampling needle body; 5. a needle tip body; 6. an arc-shaped opening; 7. a double needle mount; 8. and (5) leaving the tube unused.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a airtight sampling double needle structure of liquid material, includes base 1, sampling tank 2 and sampling needle main part 4, is provided with sampling tank 2 on the base 1, and sampling tank 2's top install rather than the sealed jar stopper 3 that the phase-match realized sealing, and the one end of sampling needle main part 4 is provided with the needle point body 5, and sampling needle main part 4 has the one end of needle point body 5 to pierce through in sealed jar stopper 3 stretches into sampling tank 2, and sampling needle main part 4 is provided with two in sampling tank 2.
Furthermore, a double-needle fixing piece 7 used for fixing the two sampling needle bodies 4 is arranged above the sealing can plug 3, and the bottom surface of the double-needle fixing piece 7 is tightly attached to the top surface of the sealing can plug 3.
Further, on the base 1, one side that is located sampling tank 2 is provided with idle pipe 8, after the sampling is accomplished, can take out sampling needle main part 4 and put into idle pipe 8, and utilize 7 mouths of pipe of idle pipe 8 of cover of double needle mounting, both accomodate sampling needle main part 4, protect it not put in disorder everywhere, can prevent again that to remain the sampling liquid in sampling needle main part 4 everywhere drippage, avoid toxic liquid to produce influence and polluted environment etc. to operator's health.
Further, the needle point body 5 is the toper structure, and the needle point body 5 of 4 bottoms of sampling needle main part sets up to the toper structure, makes in the sealed jar stopper 3 of inserting that sampling needle main part 4 can be relaxed stretches into sampling jar 2, and operation labour saving and time saving improves the acupuncture effect.
Furthermore, the sampling needle body 4 and the needle point body 5 form an integrated structure through laser welding, so that the firmness of the sampling needle is improved, the breaking probability of the sampling needle is reduced, and the service life of the sampling needle is prolonged.
Furthermore, an arc-shaped opening 6 is formed in the side wall of the sampling needle body 4, and the arc-shaped opening 6 is formed in the side wall of the sampling needle body 4, so that liquid materials can enter the sampling needle body 2 along the side wall, and splashing of the liquid due to pressure factors is avoided.
Further, the sealing tank plug 3 and the double-needle fixing piece 7 are both made of rubber and plastic materials, so that the sealing effect is improved, the sampling liquid is placed to flow out, and the sampling needle body 4 and the needle tip body 5 are convenient to insert.
The working principle is as follows: for the liquid material closed sampling double-needle structure, firstly, when sampling, the needle point bodies 5 of two sampling needle main bodies 4 are inserted into a double-needle fixing piece 7 and penetrate through the double-needle fixing piece 7, the double-needle fixing piece 7 is used for carrying out basic limiting on the two sampling needle main bodies 4, then the two sampling needle main bodies 4 are slightly rotated respectively, so that arc-shaped openings 6 of the two sampling needle main bodies can be close to a can body of a sampling can 2, and then the needle point bodies 5 are used for inserting the sampling needle main bodies 4 into a sealing can plug 3 and penetrating through the sealing can plug and extending into the sampling can 2 for sampling; during sampling, as the arc-shaped opening 6 is formed in the side wall of the sampling needle body 4, a sampling liquid material can enter the sampling needle body along the body of the sampling tank 2, and the liquid is prevented from splashing due to pressure factors; after the sampling, can take out sampling needle main part 4 together with double needle mounting 7, put into idle pipe 8 immediately afterwards and settle, double needle mounting 7 seals the mouth of pipe of idle pipe 8, just so accomplishes the use of whole airtight sampling double needle structure of liquid material.
