Description

Technical Field

[0001] This utility model relates to the field of capping mechanism technology, and more specifically, to a capping structure for centrifuge tubes. Background Technology

[0002] Centrifuge tubes are commonly used in many scientific research and industrial fields such as biomedicine, chemical analysis, and materials science to carry and separate samples. Effective sealing of centrifuge tubes is crucial to ensuring the accuracy of experimental results and preventing sample contamination and leakage. Centrifuge tube capping mechanisms have emerged to address this need. However, existing centrifuge tube capping operations mostly rely on manual operation by operators who use experience and manual force to press the cap onto the centrifuge tube. This method is inefficient, and the capping effect is greatly affected by human factors. Different operators apply different pressure and angles, resulting in inconsistent cap tightness, which affects subsequent centrifugation. To address the shortcomings of existing technologies, we propose a capping structure for centrifuge tubes. Utility Model Content

[0003] In order to overcome the above-mentioned defects of the prior art, this utility model provides a capping structure for centrifuge tubes to solve the problems of low efficiency of existing capping methods and the fact that the capping effect is greatly affected by human factors. Different operators apply different pressure and angles, resulting in inconsistent cap tightness, which affects the subsequent centrifugation work.

[0004] To solve the above technical problems, the present invention provides the following technical solution: a capping structure for centrifuge tubes, including a base, a clamping component is provided on the upper side of the base, a supporting component is provided on the inner side of the clamping component, a capping component is provided on the upper side of the clamping component, and a fan-shaped plate is fixedly installed on the upper outer surface of the base.

[0005] The clamping assembly includes a mounting frame, a connecting plate rotatably connected to the center of the inner surface of the mounting frame, a clamping component fixedly mounted on the side of the connecting plate, a connecting column fixedly mounted on the lower outer surface of the connecting plate, a gear fixedly mounted on the lower end of the connecting column, a toothed plate meshing with the outer surface of the gear, and a cylinder fixedly mounted on one outer surface of the toothed plate.

[0006] The mounting bracket is fixedly installed on one outer surface of the sector plate, the connecting column rotates on the lower inner wall of the mounting bracket, the connecting column is rotatably connected to the inner wall of the base, the toothed plate slides on the inner wall of the base, the cylinder is fixedly installed on one outer surface of the base, and the clamping member slides on the inner surface of the mounting bracket.

[0007] The support assembly includes a motor, a threaded screw fixedly mounted on the output end of the motor, a connecting block 1 threadedly connected to the outer surface of the threaded screw, support discs fixedly mounted on the two outer surfaces of the connecting block 1, the motor fixedly mounted on the upper inner wall of the connecting column, the threaded screw rotatably connected to the lower inner wall of the connecting column, the connecting block 1 sliding on the inner surface of the connecting column, and the support discs sliding on the outer surface of the connecting column.

[0008] The pressure cap assembly includes a hollow threaded column. An electric telescopic rod is fixedly installed on the lower inner wall of the hollow threaded column. A connecting block two is fixedly installed on the outer surface of the telescopic end of the electric telescopic rod. A top plate is fixedly installed at both ends of the connecting block two. A pressure block is fixedly installed on the lower outer surface of the top plate. A limit ring is threadedly connected to the outer surface of the hollow threaded column.

[0009] The center points of the hollow threaded column and the connecting column are on the same vertical axis, and the pressure block is located directly above the slot of the mounting bracket.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This utility model, through its clamping and supporting components, including a mounting frame and a motor, firstly, based on the height of the centrifuge tube, starts the motor to drive the threaded screw to rotate. The rotation of the threaded screw causes the threaded connecting block on its outer surface to slide, thereby causing the support plate to slide on the outer wall of the connecting column, so that the support plate is at a suitable height. Then, the centrifuge tube is placed inside the mounting frame on the upper outer surface of the support plate. Next, the cylinder is started to push the toothed plate to slide. The sliding of the toothed plate causes the gear to rotate, and the rotation of the gear causes the connecting column to rotate, thereby causing the connecting plate to rotate, so that the clamping component clamps the outer surface of the centrifuge tube. Using the above structure, by starting the motor and the cylinder, the clamping and supporting of the centrifuge tube is realized, which facilitates the capping of the centrifuge tube.

[0012] By observing the height of the upper end of the centrifuge tube, the limiting ring is rotated so that the upper surface of the limiting ring is level with the upper surface of the centrifuge tube. Then, the electric telescopic rod is activated to drive the connecting block two and the top plate to move synchronously, thereby driving the pressure block to apply force to the cap, completing the capping of the centrifuge tube. Using the above structure, automatic capping of centrifuge tubes is realized, which not only improves the capping efficiency of centrifuge tubes, but also achieves stability of the pressing force and angle, ensuring the consistency of the cap tightness and subsequent centrifugation work.

[0020] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

A clamping member 23 is fixedly installed on the side of the connecting plate 22. A connecting post 24 is fixedly installed on the lower outer surface of the connecting plate 22. A gear 25 is fixedly installed at the lower end of the connecting post 24. A toothed plate 26 meshes with the outer surface of the gear 25. A cylinder 27 is fixedly installed on one outer surface of the toothed plate 26.

[0023] Among them, the mounting bracket 21 is fixedly installed on one side of the outer surface of the sector plate 5, the connecting column 24 rotates on the lower inner wall of the mounting bracket 21, the connecting column 24 is rotatably connected to the inner wall of the base 1, the toothed plate 26 slides on the inner wall of the base 1, the cylinder 27 is fixedly installed on one side of the outer surface of the base 1, and the clamping member 23 slides on the inner surface of the mounting bracket 21.

[0024] By activating the cylinder 27, the toothed plate 26 is pushed to slide. The sliding of the toothed plate 26 drives the gear 25 to rotate. The rotation of the gear 25 drives the connecting column 24 to rotate, thereby driving the connecting disk 22 to rotate, so that the clamping member 23 is clamped on the outer surface of the centrifuge tube.

[0025] The support assembly 3 includes a motor 31, a threaded screw 32 fixedly installed at the output end of the motor 31, a connecting block 33 threadedly connected to the outer surface of the threaded screw 32, and support plates 34 fixedly installed on the outer surfaces of both sides of the connecting block 33. The motor 31 is fixedly installed on the upper inner wall of the connecting column 24, the threaded screw 32 is rotatably connected to the lower inner wall of the connecting column 24, the connecting block 33 slides on the inner surface of the connecting column 24, and the support plates 34 slide on the outer surface of the connecting column 24.

[0026] By starting the motor 31, the threaded screw 32 is driven to rotate. The rotation of the threaded screw 32 causes the threaded connecting block 33 on its outer surface to slide, thereby causing the support plate 34 to slide on the outer wall of the connecting column 24, so that the support plate 34 is at a suitable height.

[0027] The pressure cap assembly 4 includes a hollow threaded column 41, an electric telescopic rod 42 is fixedly installed on the lower inner wall of the hollow threaded column 41, a connecting block 43 is fixedly installed on the outer surface of the telescopic end of the electric telescopic rod 42, a top plate 44 is fixedly installed on both ends of the connecting block 43, a pressure block 45 is fixedly installed on the lower outer surface of the top plate 44, a limit ring 46 is threadedly connected to the outer surface of the hollow threaded column 41, the hollow threaded column 41 is fixedly installed on the upper outer surface of the mounting bracket 21, the connecting block 43 slides on the inner surface of the hollow threaded column 41, and the top plate 44 slides on the outer surface of the hollow threaded column 41.

[0028] By observing the height of the upper end of the centrifuge tube, rotate the limiting ring 46 so that the upper surface of the limiting ring 46 is horizontal with the upper surface of the centrifuge tube. Then, start the electric telescopic rod 42 to drive the connecting block 43 and the top plate 44 to move synchronously, thereby driving the pressure block 45 to apply force to the cap and complete the capping of the centrifuge tube.

[0029] The center points of the hollow threaded column 41 and the connecting column 24 are on the same longitudinal axis, and the pressure block 45 is located directly above the slot of the mounting bracket 21.

[0030] The working process of this utility model is as follows:

[0031] First, based on the height of the centrifuge tube, start motor 31 to drive threaded screw 32 to rotate. The rotation of threaded screw 32 causes the threaded connecting block 33 on its outer surface to slide, thereby causing support plate 34 to slide on the outer wall of connecting column 24, so that support plate 34 is at a suitable height. Then, place the centrifuge tube inside the mounting bracket 21 on the upper outer surface of support plate 34. Next, start cylinder 27 to push toothed plate 26 to slide. The sliding of toothed plate 26 causes gear 25 to rotate. The rotation of gear 25 causes connecting column 24 to rotate, thereby causing connecting plate 22 to rotate, so that clamping member 23 clamps the outer surface of centrifuge tube. After fixing, observe the height of the upper end of centrifuge tube, rotate limit ring 46 so that the upper surface of limit ring 46 is horizontal with the upper end surface of centrifuge tube. Then, start electric telescopic rod 42 to drive connecting block 43 and top plate 44 to move synchronously, thereby driving pressure block 45 to apply force to the cap, completing the capping of centrifuge tube.
