Description

Technical Field

[0001] The utility model relates to an experimental appliance, in particular to a reagent bottle opener. Background Art

[0002] Since most organic reagents are easy to volatilize, chemical reagent bottles usually include a bottle body, and the bottle mouth of the bottle body is provided with an inner plug and an outer cover. The inner plug seals the bottle mouth and then screws on the outer cover. Sometimes the outer cover is screwed too tight and it is not easy to loosen it completely by hand; since the inner plug is made of hard plastic, it fits the bottle cap very tightly and is very difficult to open. In addition, when opening the inner plug, if too much force is used, the liquid reagent in the reagent bottle may splash out, causing pollution. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a reagent bottle opener which can easily open an outer cover and an inner plug and prevent liquid reagent in the reagent bottle from splashing out.

[0004] In order to solve the above technical problems, the technical solution of the utility model is: a reagent bottle opener, comprising an operating rod, a first operating head arranged at one end of the operating rod for opening an outer cover, and a second operating head arranged at the other end of the operating rod for opening an inner plug; the first operating head is U-shaped, comprising two symmetrically arranged first operating arms, the two first operating arms form a U-shaped groove, and the inner side of the first operating arm is provided with anti-slip grooves; the second operating head is V-shaped, comprising two symmetrically arranged second operating arms, the two second operating arms form a V-shaped groove, a protective cover is provided above the V-shaped groove, and the thickness of the second operating arm gradually becomes thinner from the rear end to the front end. The principle of the utility model is as follows: when it is necessary to open the outer cover of the reagent bottle, the operating rod is held, the two first operating arms of the first operating head clamp the outer cover, and the first operating head is rotated. Through the lever principle and the anti-skid pattern, the outer cover can be easily loosened and opened; when it is necessary to open the inner plug of the reagent bottle, the operating rod is held, the two second operating arms of the second operating head clamp the outer cover, and the bottle mouth is used as a fulcrum to pry the inner plug through the lever principle, so that the inner plug can be easily opened; because a protective cover is arranged above the V-shaped groove, liquid reagent in the reagent bottle can be blocked from splashing out.

[0005] As an improvement, the operating rod, the first operating head, the second operating head and the protective cover are integrally injection molded.

[0006] As an improvement, the protective cover is a transparent cover.

[0007] Compared with the prior art, the utility model has the following beneficial effects:

[0008] When it is necessary to open the outer cover of the reagent bottle, hold the operating lever, clamp the outer cover with the two first operating arms of the first operating head, rotate the first operating head, and easily loosen and open the outer cover through the lever principle and anti-slip texture; when it is necessary to open the inner plug of the reagent bottle, hold the operating lever, clamp the outer cover with the two second operating arms of the second operating head, use the bottle mouth as a fulcrum, and pry the inner plug through the lever principle to easily open the inner plug; since a protective cover is arranged above the V-shaped groove, it can prevent the liquid reagent in the reagent bottle from splashing out.

[0012] The utility model will be further described below in conjunction with the accompanying drawings.

[0013] A reagent bottle comprises a bottle body, an inner plug arranged at the bottle mouth and an outer cover, wherein the inner plug comprises a plug head and an annular flange arranged on the plug head, and an outer side surface of the outer cover is provided with anti-slip grooves.

[0014] like Figures 1 to 3As shown, a reagent bottle opener is used to open an outer cover and an inner plug, which includes an operating rod 1, a first operating head 2 provided at one end of the operating rod 1 for opening the outer cover, and a second operating head 3 provided at the other end of the operating rod 1 for opening the inner plug. The first operating head 2 is U-shaped, and includes two symmetrically arranged first operating arms 21, and the two first operating arms 21 form a U-shaped groove 22. The inner side of the first operating arm 21 is provided with anti-slip grooves 23. During operation, the outer cover is placed in the U-shaped groove 22, and the first operating arm 21 is located on both sides of the outer cover. The design of the U-shaped groove 22 can increase the contact area between the first operating arm 21 and the outer cover, and the inner side of the U-shaped groove 22 is gradually narrowed, which can also adapt to the operation of outer covers with larger diameters. The second operating head 3 is V-shaped, and includes two symmetrically arranged second operating arms 31, and the two second operating arms 31 form a V-shaped groove 32. The thickness of the second operating arm 31 gradually becomes thinner from the rear end to the front end. During operation, the front end of the second operating arm 31 is used to act between the annular flange of the inner plug and the bottle mouth, first lift the inner plug a little, and then move the second operating head 3 horizontally to place the inner plug into the V-shaped groove 32. During the movement of the second operating arm 31, due to its gradually increasing thickness, the inner side of the second operating arm 31 can act on the bottom of the annular flange and gradually lift the inner plug. The design of the V-shaped groove 32 can adapt to inner plugs of different diameters; a protective cover 33 is provided above the V-shaped groove 32. The protective cover 33 is a transparent cover that does not affect observation during operation and can prevent splashing. The operating rod 1, the first operating head 2, the second operating head 3 and the protective cover 33 are integrally injection molded.

[0015] Principle of the utility model: when it is necessary to open the outer cover of the reagent bottle, hold the operating rod 1, clamp the outer cover with the two first operating arms 21 of the first operating head 2, rotate the first operating head 2, and through the lever principle and the anti-slip texture, the outer cover can be easily loosened and opened; when it is necessary to open the inner plug of the reagent bottle, hold the operating rod 1, clamp the outer cover with the two second operating arms 31 of the second operating head 3, use the bottle mouth as a fulcrum, pry the inner plug through the lever principle, and the inner plug can be easily opened; because the protective cover 33 is arranged above the V-shaped groove 32, the liquid reagent in the reagent bottle can be blocked from splashing out.
