Abstract

The invention discloses a novel test tube sealer which comprises a cover body, wherein an annular crack is formed in the side wall of the cover body and divides the side wall of the cover body into an outer wall and an inner wall, a waterproof plastic sleeve is adhered to the inner side of the outer wall, an annular groove is formed in the outer side of the outer wall, and a locking hoop is installed in the annular groove. Compared with the wood plugs and rubber plugs which are widely used at present, the invention not only can meet the sealing requirement of the test tube, but also can effectively limit the volatilization of the reagent in the experimental processes of water bath, ignition and the like. When using the test tube to store the material as the container, more conveniently deposit after sealing process to the test tube with this test tube sealer. In addition, this test tube sealer simple structure, the leakproofness is good, and low in cost can be used as disposable article completely, can effectually avoid the loaded down with trivial details and the reagent risk of polluting of the abluent repetition of current test tube stopper.

Description

Test tube sealer

Technical Field

The invention relates to a test tube sealer, and belongs to the technical field of measuring tools.

Background

The tube sealer is a special condition and tool for sealing the mouth of a test tube and providing sealing when a substance requiring a sealed environment is present in the test tube. In various laboratory places such as inorganic chemistry, organic chemistry, biochemistry and the like, a test tube is one of experimental devices with very high use frequency. In the course of various experiments, it is often necessary to burn, bathe or store the test substance together with the test tube. At the present stage, a test tube plug such as a wooden plug or a rubber plug is adopted for sealing a test tube, and although the test tube plug can play a certain sealing role, the test tube plug has the defects of large volume and mass, and easy pollution and damage, and is always subjected to scaling by experimenters. In addition, the test tube plug is not easy to pull out after being stored on the test tube for a certain time or after the heated test tube is cooled, which brings inconvenience to the experiment.

Disclosure of Invention

In order to overcome the problems in the prior art, the invention provides the test tube sealer which is low in manufacturing cost, simple in structure, convenient to operate, convenient to carry and better in sealing performance.

The technical scheme of the invention is as follows: the utility model provides a test tube sealer, includes the lid, has seted up annular crack in the lateral wall of lid, and outer wall and inner wall are separated into with the lateral wall of lid to annular crack, is stained with waterproof plastic cover in the inboard of outer wall, has seted up the ring channel on the outside of outer wall, installs the locking staple bolt in the ring channel.

Further, the length of the lower end of the outer wall is larger than that of the lower end of the inner wall, and a chamfer is arranged on the outer side of the lower end of the inner wall.

Furthermore, the waterproof plastic sleeve extends out of the opening of the cover body from the inner side of the outer wall and exceeds the end face of the opening of the cover body.

Furthermore, the waterproof plastic sleeve is made of hydrophobic single-sided sticky plastic.

Further, the locking staple bolt is the loop configuration, is provided with the circular bead of mutual butt joint on two free ends of locking staple bolt, is provided with the draw-in groove on the circular bead of inboard, be provided with on the circular bead of outside with draw-in groove complex dop, be provided with the pulling-on piece in the outside of dop.

Due to the adoption of the technical scheme, the invention has the advantages that: compared with the wood plugs and rubber plugs which are widely used at present, the invention not only can meet the sealing requirement of the test tube, but also can effectively limit the volatilization of the reagent in the experimental processes of water bath, ignition and the like. When using the test tube to store the material as the container, more conveniently deposit after sealing process to the test tube with this test tube sealer. In addition, this test tube sealer simple structure, the leakproofness is good, and low in cost can be used as disposable article completely, can effectually avoid the loaded down with trivial details and the reagent risk of polluting of the abluent repetition of current test tube stopper.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be further described in detail with reference to the accompanying drawings and examples.

The embodiment of the invention comprises the following steps: the structure schematic diagram of the test tube sealer is shown in fig. 1, and comprises a cover body 1, wherein an annular crack 4 is formed in the side wall of the cover body 1, the side wall of the cover body 1 is divided into an outer wall 2 and an inner wall 3 by the annular crack 4, a waterproof plastic sleeve 6 is adhered to the inner side of the outer wall 2, an annular groove 8 is formed in the outer side of the outer wall 2, and a locking hoop 5 is installed in the annular groove 8. The length of outer wall 2 lower extreme is greater than the length of inner wall 3 lower extreme, and the inner wall 3 lower extreme outside is provided with chamfer 7, waterproof plastic cover 6 extends the oral area of lid 1 from the inboard of outer wall 2 to surpass the oral area terminal surface of lid 1. The waterproof plastic sleeve 6 is made of hydrophobic single-sided viscous plastic. Referring to fig. 2 and 3, the locking hoop 5 is of an annular structure, two free ends of the locking hoop 5 are provided with shoulders which are butted with each other, a clamping groove 9 is arranged on the inner shoulder, a clamping head 10 matched with the clamping groove 9 is arranged on the outer shoulder, and a pulling piece 11 is arranged on the outer side of the clamping head 10.

Referring to fig. 4, during the use, insert the mouth of pipe of test tube in lid 1, make the oral area lateral wall embedding annular crack 4 of test tube, the oral area outer wall of test tube is hugged closely to waterproof plastic cover 6 this moment, wraps up the extension of waterproof plastic cover 6 on the test tube outer wall simultaneously, reaches sealed waterproof effect, avoids polluting the oral area of test tube. Finally, the clamping head 10 of the locking hoop 5 is clamped into the clamping groove 9, so that the locking hoop 5 tightly holds the outer wall 2 of the cover body 1, the waterproof plastic sleeve 6 on the inner side of the outer wall 2 is in full contact with the outer wall of the pipe orifice of the test tube, and the secondary fixing and waterproof effects are achieved.

Therefore, compared with the wood plugs and rubber plugs which are widely used at present, the invention not only can meet the sealing requirement of the test tube, but also can effectively limit the volatilization of the reagent in the experimental processes of water bath, burning and the like. When using the test tube to store the material as the container, more conveniently deposit after sealing process to the test tube with this test tube sealer. In addition, this test tube sealer simple structure, the leakproofness is good, and low in cost can be used as disposable article completely, can effectually avoid the loaded down with trivial details and the reagent risk of polluting of the abluent repetition of current test tube stopper.
