[0033] Chemical reagents are relative standard materials for chemical research and component analysis, and are important conditions for scientific and technological progress. They are widely used in synthesis, separation, qualitative and quantitative analysis of substances, and can be said to be the eyes of chemical workers. In daily work in factories, schools, hospitals and research institutes, chemical reagents cannot be separated. They have been widely used in industry, agriculture, medical and health care, life science, inspection and quarantine, environmental protection, energy development, national defense and military industry, scientific research and various industries of national economy. When storing chemical reagents, a chemical reagent storage cabinet is involved, which is specially used for storing chemical reagents.

[0034] In the related art, after the reagent tube is inserted into the placing groove, the reagent tube will extrude the clamping block, so that the extrusion block extrudes the spring. At this time, the clamping block is pushed to clamp the reagent tube by relying on the elastic force of the spring. However, the existing device relies on the rebound force of the spring to clamp the reagent tube when in use, and cannot completely stabilize the reagent tube. When the reagent storage cabinet is bumped, the reagent tube will still extrude the spring due to inertia, so the fixation of the reagent tube is not firm enough.

[0035] In order to solve the problems in the related art to some extent, the present application provides a chemical reagent storage cabinet. When it is necessary to store chemical reagents, the box door of the box body 11 needs to be opened first, and then the bottom end of the reagent tube is inserted into the hole on the placing plate 12, and the tube body 21 is inserted into the inside of the base 25. At this time, the reagent tube needs to be clamped and fixed. At this time, the threaded rod 27 can be rotated. When rotating, the threaded rod 27 is screwed with the lug plate 26, which will drive the lug plate 26 to move downward and push the base 25 to move downward, which will drive the connecting rod 24 to rotate, so that the connecting rod 24 drives the cross rod 22 to insert into the inside of the tube body 21 and push the clamping plate 23 to clamp and fix the reagent tube.

[0036] The present application will be described below in conjunction with the drawings and specific embodiments:

[0037] In combination Figures 1-5The embodiment of the present application provides a chemical reagent storage cabinet, which comprises a box body 11, a placing plate 12 is arranged in the box body 11, a clamping assembly 2 is arranged at the bottom of the placing plate 12, the clamping assembly 2 comprises a pipe body 21, the pipe body 21 is arranged below the hole of the placing plate 12, a cross rod 22 is inserted into the inside of the pipe body 21, a clamping plate 23 is arranged at one end of the cross rod 22, a connecting rod 24 is rotationally connected to one end of the clamping plate 23, a base 25 is arranged below the pipe body 21 and rotationally connected to the bottom end of the connecting rod 24, a convex plate 26 is arranged on the outer side wall of the base 25, and a threaded rod 27 is rotationally connected to the placing plate 12 and screw-connected with the convex plate 26.

[0038] When the chemical reagent needs to be stored, first, the box door of the box body 11 is opened, then the bottom end of the reagent tube is inserted into the hole on the placing plate 12, the pipe body 21 is inserted into the inside of the base 25, at this time, the reagent tube needs to be clamped and fixed, at this time, the threaded rod 27 can be rotated, when rotating, because the threaded rod 27 is screw-connected with the convex plate 26, the convex plate 26 is driven to move downward and push the base 25 to move downward, the connecting rod 24 is rotated, the connecting rod 24 drives the cross rod 22 to be inserted into the inside of the pipe body 21 and push the clamping plate 23 to clamp and fix the reagent tube.

[0039] In some embodiments, the clamping assembly 2 further comprises a rotating handle 28 arranged at the bottom of the threaded rod 27.

[0040] When in use, the rotating handle 28 is convenient to grasp and control the rotation of the threaded rod 27, and the grooves on the surface of the rotating handle 28 can increase friction when rotating.

[0041] In some embodiments, the clamping assembly 2 further comprises a rubber convex strip 29 arranged on the inner side wall of the clamping plate 23.

[0042] When in use, the rubber convex strip 29 is designed to protect the outer side wall of the reagent tube from being scratched, and can increase friction, so that clamping and fixing are more firm.

[0043] In some embodiments, the top of the placing plate 12 is provided with a pressing assembly 3, the pressing assembly 3 comprises a shell 31 arranged at the top of the placing plate 12, a vertical rod 32 is inserted into the inside of the shell 31, a pressing plate 33 is arranged at the top of the vertical rod 32, a bottom plate 34 is rotationally arranged at the bottom of the vertical rod 32, and a spring one 35 is arranged at the top of the bottom plate 34 and connected to the inner side wall of the shell 31.

[0044] When the reagent tube is clamped and fixed, the pressing plate 33 can be pulled upwards, and the vertical rod 32 is extracted from the inside of the shell 31, and the bottom plate 34 is pressed to the spring 35. Then, the pressing plate 33 is rotated to be located at the top of the reagent tube, and the spring 35 is released. After the bottom plate 34 is pushed down by the spring 35, the vertical rod 32 is lowered, so that the pressing plate 33 can press the top end of the reagent tube.

[0045] In some embodiments, the spring 35 is sleeved outside the vertical rod 32.

[0046] When the spring 35 is sleeved outside the vertical rod 32, the spring 35 can be limited by the vertical rod 32 when compressed, so as to better protect the spring 35.

[0047] In some embodiments, the pressing assembly 3 further comprises a sponge pad 36 arranged at the bottom of the pressing plate 33.

[0048] When the sponge pad 36 is designed, the top of the reagent tube can be better protected.

[0050] When the reagent tube is taken, the rotating rod 41 can be rotated to drive the placing plate 12 to rotate and adjust the position. At the same time of rotating, the arc-shaped groove 42 extrudes the positioning rod 44, so that one end of the positioning rod 44 moves out of the inside of the arc-shaped groove 42 and pushes the baffle 46 to drive the spring 45 to stretch. Until one end of the positioning rod 44 is aligned with the next arc-shaped groove 42, the spring 45 retracts to drive the baffle 46 to move, so that one end of the positioning rod 44 is inserted into the inside of the arc-shaped groove 42. When the arc-shaped groove 42 is engaged with one end of the positioning rod 44, the rotating rod 41 can be limited to rotate, so as to facilitate taking the reagent tube.

[0051] In some embodiments, one end of the positioning rod 44 is arc-shaped and is fitted with the inner side wall of the arc-shaped groove 42.
