Reagent bottle safety connection device and reagent bottle assembly Technical Field

[0001] This utility model relates to the field of chemical instrument technology, and in particular to a reagent bottle safety connection device and reagent bottle assembly. Background Technology

[0002] Reagent bottles are widely used in chemical or pharmaceutical fields to store various chemical reagents. Most of the bottles used to hold liquid chemical reagents are glass. To ensure better sealing, most reagent bottles have a plastic stopper inserted at the inlet end. The stopper is usually cylindrical with a shoulder on the upper edge.

[0003] Currently, reagent bottle stoppers have the following defects in actual use: Since the diameter of the inlet end of each reagent bottle is different, each reagent bottle is matched with a stopper of the appropriate diameter. However, during the experiment, after the user pulls the stopper out of the inlet end of the reagent bottle, they usually place it on the lab bench. But this way of handling the stopper can easily lead to the loss of the stopper. At the same time, after a long period of use, the outer surface of the stopper is prone to sticking to the inlet end of the reagent bottle.

[0004] Therefore, a reagent bottle safety connection device and a reagent bottle assembly are provided to solve the above-mentioned problems existing in the prior art. Summary of the Invention

[0005] The purpose of this utility model is to provide a reagent bottle safety connection device and reagent bottle assembly to solve the problems existing in the prior art, enabling the bottle stopper to have an anti-loss function and effectively preventing the bottle stopper from sticking to the inlet end of the reagent bottle.

The anti-stick connecting piece is wrapped around the outer surface of the bottle stopper 2 and is detachably connected to the bottle stopper 2. The connecting rope 3 is passed through the top of the bottle stopper 2. The anti-stick connecting piece is movably disposed on the connecting rope 3, and the connecting rope 3 can be connected to the bottle stopper 2 of other reagent bottles 1.

[0030] In this embodiment, the reagent bottle safety connection device is suitable for use with multiple reagent bottles 1. When the solvent in a particular reagent bottle 1 needs to be used, simply pull out the stopper 2 and the anti-stick connecting piece from the inlet end of the reagent bottle 1 to start using it. The stopper 2 after being pulled out is connected in series with the stoppers 2 on other reagent bottles 1 via the connecting rope 3, thereby giving the stopper 2 an anti-loss function. Moreover, in this embodiment, an anti-stick connecting piece is provided. When the stopper 2 is inserted into the inlet end of the reagent bottle 1, the anti-stick connecting piece wraps around the outer surface of the stopper 2, which can effectively prevent the stopper 2 from sticking to the inlet end of the reagent bottle 1.

[0031] In this embodiment, two anti-stick connecting pieces are provided, and the two anti-stick connecting pieces can respectively wrap around both sides of the bottle stopper 2.

[0032] In this embodiment, the anti-stick connecting piece includes a sealing sheet 7 and a locking block 6. Multiple locking blocks 6 are evenly arranged on the top of the sealing sheet 7 along its length direction. Multiple locking slots 4 are correspondingly arranged on the outer edge of the top of the bottle stopper 2. The locking block 6 can be locked into the corresponding locking slot 4 to fix the sealing sheet 7. The locking block 6 is movably arranged on the connecting rope 3.

[0033] In this embodiment, the thickness of the sealing sheet 7 gradually increases from bottom to top, so that the anti-stick connecting sheet can be inserted into the inlet end of the reagent bottle 1 together with the bottle stopper 2; furthermore, the thickness of the locking block 6 is greater than the thickness of the sealing sheet 7, the lower surfaces of the plurality of locking blocks 6 are fixedly connected to the upper surface of the sealing sheet 7, and the top of the locking block 6 is provided with a through hole for the connecting rope 3 to pass through, and the locking block 6 can be movably mounted on the connecting rope 3 through the through hole.

[0034] Furthermore, the top of the bottle stopper 2 is also provided with a perforation for the connecting rope 3 to pass through.

Then, insert the wrapped bottle stopper 2 into the inlet end of the reagent bottle 1 to seal the reagent bottle 1. After sealing, thread a new anti-stick connecting piece and reagent bottle 1 through the connecting rope 3 to prevent the bottle stopper 2 from being lost.

[0042] This embodiment also provides a reagent bottle assembly, including a reagent bottle 1 and a reagent bottle safety connection device as described above.
