[0001] The utility model relates to the technical field of reagent bottles, in particular to a reagent bottle with a function of preventing samples in the reagent bottle from splashing. Background Art

[0002] A reagent bottle is composed of a reagent bottle body and a reagent bottle cap. In the prior art, the installation relationships between the bottle body and the cap are respectively a ground glass fitting method, a threaded connection method, and a rubber stopper sealing method. Among them, after a long time of installation between the bottle body and the cap in the ground glass fitting method, the cap will be fixed at the bottle mouth of the bottle body. In order to remove the cap from the bottle mouth, operations such as multiple knocking, thermal expansion and contraction, or forceful rotation are usually adopted. When removing the cap by knocking and forceful rotation, due to the large amplitude of the shaking of the bottle body, it is easy to drive the chemical solvent in the bottle body to shake synchronously. When removing the cap, the chemical solvent inside the bottle body is easy to splash out from the bottle mouth, and the splashed chemical solvent is easy to cause harm to the operator. Content of the Utility Model

[0003] The purpose of the utility model is to solve the deficiencies existing in the prior art, and a reagent bottle with a function of preventing samples in the reagent bottle from splashing is proposed.

[0019] The following description is used to disclose the present utility model so that those skilled in the art can implement the present utility model. The following preferred embodiments are only examples, and those skilled in the art can think of other obvious variations.

[0020] Such as Figures 1-4A reagent bottle with the function of preventing samples in the reagent bottle from splashing, including a bottle body 1 and a bottle cap 4. The bottle cap 4 is placed at the bottle mouth of the bottle body 1. A mounting rod 7 is connected below the bottle cap 4. The bottom end of the mounting rod 7 is installed with a chemical-resistant film 6 through a contraction mechanism. The surface of the chemical-resistant film 6 is in contact with the inner surface of the bottle body 1. The contraction mechanism includes a plurality of connecting rods 5. There are at least four connecting rods 5, and the connecting rods 5 are arranged at equal angles. One ends of the plurality of connecting rods 5 are movably installed at the bottom end of the mounting rod 7, and the other ends of the plurality of connecting rods 5 are bonded to the surface of the chemical-resistant film 6. Tensile springs 8 are installed between the tops of the plurality of connecting rods 5 and the side surface of the mounting rod 7 through screws. When the plurality of connecting rods 5 contract on the mounting rod 7, the connecting rods 5 will pull the tensile springs 8, and the lengths of the tensile springs 8 will elongate after being stressed. When the plurality of connecting rods 5 expand, the tensile springs 8 drive the connecting rods 5 to reset through their own elastic potential energy, thereby facilitating the expansion or contraction of the chemical-resistant film 6 in the bottle body 1 and facilitating the operation of the staff.

[0021] A fixing shaft 10 is installed through one end of the connecting rod 5. Both ends of the fixing shaft 10 are installed with fixing blocks 9 through screws. One ends of the two fixing blocks 9 are installed on the side surface of the mounting rod 7 through screws. The fixing shaft 10 allows the connecting rod 5 to move in an arc on its surface after being stressed. The setting of the plurality of fixing shafts 10 facilitates the synchronous expansion or contraction of the plurality of connecting rods 5 on the mounting rod 7 for controlling the expansion or contraction of the chemical-resistant film 6.

[0022] A stud 2 is welded to the top end of the mounting rod 7. The stud 2 passes through the surface of the bottle cap 4 and extends upward. A screw tube 3 is threadedly sleeved on the top end of the stud 2. The cooperation of the screw tube 3 and the stud 2 facilitates the stable connection between the mounting rod 7 and the bottle cap 4.

[0023] A rubber washer 11 is bonded to the bottom of the screw tube 3. The bottom of the rubber washer 11 is in contact with the top of the bottle cap 4. The rubber washer 11 improves the sealing performance of the contact between the screw tube 3 and the bottle cap 4. The rubber washer 11 is a polyvinyl chloride washer, which can prevent the corrosive gas volatilized from the chemical solvent from leaking from the gap between the bottle cap 4 and the stud 2, improving the safety of the surrounding environment where the reagent bottle is located.

[0024] The chemical-resistant film 6 is a high-density polyethylene film, and the high-density polyethylene film can resist chemical corrosion, improving the stability of blocking the splashing of chemical solvents in the bottle body 1.

[0025] The radial dimension of the chemical-resistant film 6 after expansion is larger than the radial dimension of the bottle mouth, facilitating the chemical-resistant film 6 to block the bottle mouth after being expanded in the bottle body 1 to prevent the chemical solution from splashing out from the bottle mouth when it shakes.

[0026] Working principle: When removing the bottle cap 4 from the bottle body 1, pull the bottle cap 4 forcefully. After the bottle cap 4 is stressed, it pulls the stud 2 through the screw tube 3. The stud 2 pulls multiple connecting rods 5 through the mounting rod 7. One end of each of the multiple connecting rods 5 contacts the corner of the bottle body 1. With the pulling of the mounting rod 7, one end of each of the multiple connecting rods 5 is restricted by the corner of the bottle body 1, so that while the other end of each of the multiple connecting rods 5 is pulled by the mounting rod 7 and moves, it moves in an arc on the surface of the fixed shaft 10, causing the multiple connecting rods 5 to drive the chemical-resistant film 6 to contract. While the other end of each of the multiple connecting rods 5 moves, it slides in the bottle mouth of the bottle body 1, and the side of the chemical-resistant film 6 contacts the inner wall of the bottle mouth. After the bottle cap 4 is removed from the bottle mouth, the chemical-resistant film 6 is still in the bottle mouth. Therefore, the chemical-resistant film 6 can block the splashing of the chemical solution in the bottle body 1. By continuing to pull the bottle cap 4, after the bottle cap 4 drives the chemical-resistant film 6 out of the bottle mouth, it is convenient for the operator to pour or add the chemical solution normally.

[0027] When moving the chemical-resistant film 6 into the bottle body 1, an external force needs to be applied to the multiple connecting rods 5 in advance. The multiple connecting rods 5 are stressed and drive the chemical-resistant film 6 to contract. When the multiple connecting rods 5 contract to a position where they can be placed into the bottle mouth, the chemical-resistant film 6, the multiple connecting rods 5, and the mounting rod 7 can be placed at the bottle mouth. Then press the stud 2 to make the chemical-resistant film 6, the multiple connecting rods 5, and the mounting rod 7 move in the bottle mouth. After the chemical-resistant film 6 and the multiple connecting rods 5 move below the bottle mouth, the stretched tension springs 8 reset without resistance, causing the multiple tension springs 8 to pull the multiple connecting rods 5 to drive the chemical-resistant film 6 to unfold. Then pull the stud 2 upward, and the stud 2 pulls the multiple connecting rods 5 to move upward, facilitating the multiple connecting rods 5 to drive the chemical-resistant film 6 to be in close contact with the inner wall of the bottle body 1. Then rotate the screw tube 3. After the bottom of the screw tube 3 contacts the top of the bottle cap 4, the chemical-resistant film 6 can stably block the bottle mouth.
