[0001] The utility model relates to the technical field of reagent bottles, in particular to an anti-pollution reagent bottle. Background Technique

[0002] Reagent bottles are containers used to store liquid or solid chemical reagents, and they play a crucial role in chemical laboratories.

[0003] In a chemical laboratory, the storage and use of reagents are extremely vulnerable to contamination. When storing reagents in reagent bottles, they need to be sealed. Traditional reagent bottles usually use a sealing ring to seal between the bottle mouth and the bottle cap, and the bottle cap and the bottle mouth are usually installed by means of a threaded connection. When the bottle cap rotates, it is easy to drive the sealing ring to rotate, which makes the sealing ring easy to rub against the top of the bottle mouth, easily causing wear of the sealing ring material, thus affecting the sealing performance of the sealing ring, making it necessary for staff to frequently replace it, which is too troublesome. Moreover, frequently replacing the sealing ring easily increases unnecessary cost expenditures. Content of the Utility Model

[0022] The principles and features of the present utility model will be described below with reference to the attached drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0023] As Figures 1 to 5 shown, Embodiment 1 of the present utility model is an anti-pollution reagent bottle, which includes a bottle body 1. The top of the bottle body 1 is connected to a bottle mouth 2, and a positioning member 3 is arranged on the top of the bottle mouth 2;

[0024] The positioning member 3 includes an annular fixed groove 31 opened on the top of the bottle mouth 2. A sealing ring is placed on the inner bottom wall of the fixed groove 31, and several positioning rods 32 are fixedly installed on the inner bottom wall of the fixed groove 31. Several positioning rods 32 vertically penetrate through the sealing ring;

[0025] It further includes a bottle cap 4 threadedly installed on the bottle mouth 2, and a sealing assembly 5 is arranged inside the bottle cap 4; The sealing assembly 5 includes a positioning plate 51 arranged inside the bottle cap 4. A sealing cover 52 is arranged on the lower surface of the positioning plate 51. The size of the sealing cover 52 is matched with the size of the fixed groove 31, so that the sealing cover 52 can be inserted into the fixed groove 31. A rubber ring 53 is fixedly installed on the lower surface of the sealing cover 52. A positioning groove 54 that is mutually connected and matched with the positioning rod 32 is opened on the lower surface of the rubber ring 53 and inside the sealing cover 52.

[0026] By opening the fixed groove 31 on the top of the bottle mouth 2, the sealing ring does not need to be placed on the top of the bottle cap 4. Among them, several positioning rods 32 penetrate through the sealing ring, so that the positioning rods 32 limit the sealing ring, avoiding the sealing ring from rotating and accelerating wear, extending the service life of the sealing ring, and enabling the staff to not need to frequently replace the sealing ring. By arranging the sealing cover 52 and the rubber ring 53 inside the bottle cap 4, when the bottle cap 4 is installed on the bottle mouth 2, the sealing cover 52 can be inserted into the inside of the fixed groove 31, so that the sealing cover 52 can drive the rubber ring 53 to contact the top of the sealing ring, which can not only limit the top of the sealing ring, but also further improve the sealing performance of the structure through the mutual fitting between the rubber ring 53 and the sealing ring, facilitating the storage of the reagent.

[0027] Embodiment 2 of the utility model: An anti-pollution reagent bottle. On the basis of Embodiment 1, a bearing 9 is fixedly installed on the lower surface of the positioning plate 51, and the sealing cover 52 is fixedly installed on the inner wall of the bearing 9. The sealing cover 52 is rotatably installed at the bottom of the positioning plate 51 through the bearing 9.

[0028] By setting the bearing 9, when the bottle cap 4 rotates, the sealing cover 52 can remain relatively stationary under the limitation of the positioning rod 32, thereby avoiding the rotation of the rubber ring 53 and thus preventing friction on the sealing ring.

[0029] Embodiment 3 of the utility model: An anti-pollution reagent bottle. On the basis of Embodiment 1 or 2, a fixing rod 10 is fixedly installed on the upper surface of the positioning plate 51. The other end of the fixing rod 10 extends to the top of the bottle cap 4 and is fixedly installed with a pressing handle 11. A plurality of finger holes are formed on the surface of the pressing handle 11.

[0030] By setting the fixing rod 10 and the pressing handle 11, when the bottle cap 4 is threadedly installed on the bottle mouth 2, by pressing the fixing rod 10 through the pressing handle 11, the fixing rod 10 drives the positioning plate 51 to move downward, and then drives the sealing cover 52 to move downward, so that the rubber ring 53 can be mutually extruded with the sealing ring, increasing the pressure on the contact surface between the rubber ring 53 and the sealing ring, effectively preventing liquid, gas or solid particles from leaking from the sealing surface, and improving the sealing performance.

[0031] Embodiment 4 of the utility model: An anti-pollution reagent bottle. On the basis of Embodiment 3, a magnet ring 12 is fixedly installed on the inner top wall of the bottle cap 4, and an iron sheet 13 is fixedly sleeved on the surface of the fixing rod 10 and directly below the magnet ring 12.

[0032] It should be noted that the suction force of the magnet ring 12 can support the sealing assembly 5.

[0033] When the staff needs to remove the bottle cap 4, by driving the fixing rod 10 to move upward through the pressing handle 11, the sealing cover 52 is driven to move upward, so that a part of the sealing cover 52 can be separated from the fixing groove 31. At this time, the magnet ring 12 contacts the iron sheet 13. Through the magnetic suction force between the magnet ring 12 and the iron sheet 13, when the staff rotates the bottle cap 4, there is no need to lift the pressing handle 11, which is time-saving and labor-saving.

[0034] Embodiment 5 of the utility model: An anti-pollution reagent bottle. On the basis of Embodiments 1 to 4, two vertical grooves 6 are oppositely formed on the inner wall of the bottle cap 4. Annular grooves 7 are formed at the bottoms of the two vertical grooves 6, and the two annular grooves 7 are not connected to each other; sliding blocks 8 slidably connected to the inner walls of the corresponding vertical grooves 6 are fixedly installed on both side surfaces of the positioning plate 51.

[0035] Through the cooperation between the vertical groove 6 and the slider 8, the positioning plate 51 can move downward stably. By setting the annular groove 7, when the sealing cover 52 presses the sealing ring, the positioning plate 51 is rotated by the pressing handle 11, so that the slider 8 moves along the annular groove 7. At this time, the inner top wall and the inner bottom wall of the annular groove 7 limit the slider 8, so that the staff does not need to keep pressing the pressing handle 11.

[0036] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
