DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

A clamping mechanism 4 for supporting centrifuge tubes of different sizes is provided on the support plate 2, thereby improving the adaptability of the centrifuge tube holder to centrifuge tubes of different sizes. A placement hole 5 is provided on the upper surface of the support plate 2, and a centrifuge tube body 6 is provided inside the placement hole 5.

[0023] Among them, the support plate 2 is shaped like a hollow rectangular parallelepiped, and the placement hole 5 passes through and extends to the lower surface of the support plate 2 so that the centrifuge tube body 6 can pass through the support plate 2 for placement, and the inner diameter of the placement hole 5 is larger than the outer diameter of the centrifuge tube body 6.

[0024] See also Figure 2 In order to facilitate adjusting the height of the bracket according to the height of the centrifuge tube, the adjustment mechanism 3 in this embodiment includes a positioning rod 301, the positioning rod 301 is fixed to the upper surface of the bottom plate 1, the outer side of the positioning rod 301 is slidably connected with a rod sleeve 302, the top of the rod sleeve 302 is fixed to the lower surface of the support plate 2, the support plate 2 is lifted from the bottom to the top, the support plate 2 drives the rod sleeve 302 to move, the rod sleeve 302 slides on the outer side of the positioning rod 301, and the outer side of the positioning rod 301 is provided with a mounting groove 303, the mounting groove 303 A first spring 304 is fixed to the right inner wall, and a block 305 is fixed to the other end of the first spring 304. The left side of the block 305 is an upwardly inclined slope. A slot 306 is provided on the inner side of the rod sleeve 302. When the rod sleeve 302 moves upward, the inner wall of the rod sleeve 302 will squeeze the block 305 into the installation slot 303, so that the first spring 304 is compressed. When the slot 306 moves to the block 305, the first spring 304 will bounce the block 305 into the slot 306. Since the left side of the block 305 is The upwardly inclined surface will not hinder the support plate 2 from moving upward. When adjusted to a suitable height, the block 305 pops into the corresponding slot 306. At this time, the support plate 2 can continue to move upward but cannot move downward. When the centrifuge tube body 6 is placed, the centrifuge tube body 6 exerts a downward force on the support plate 2 without causing the position of the support plate 2 to deviate. A second spring 307 is fixed to the outside of the rod sleeve 302. The other end of the second spring 307 is fixed to a connecting plate 308. The right side of the connecting plate 308 A connecting rod 309 is fixed on the side, and the other end of the connecting rod 309 passes through and extends to the inside of the slot 306, and a push block 310 is fixed. When the position of the support plate 2 needs to be adjusted downward, the connecting plate 308 is pressed, and the connecting plate 308 drives the connecting rod 309 to move, and the connecting rod 309 drives the push block 310 to move. The push block 310 pushes the block 305 inside the slot 306 out, so that the position of the rod sleeve 302 loses its fixing effect. At this time, the position of the support plate 2 can be adjusted at will, and a support assembly is provided on the base plate 1.

[0025] In this example, the number of the slots 306 is no less than two and is evenly distributed on the inner side of the rod sleeve 302. The number of connecting rods 309 is equal to the number of the slots 306 and the positions correspond one to one, so that the support plate 2 can be adjusted to multiple different heights.

[0026] It should be noted that the support assembly includes a support rod 311, one end of the support rod 311 is fixed to the upper surface of the base plate 1, and a slider 312 is fixed to the other end of the support rod 311. The outer side of the slider 312 is slidably connected to a support sleeve 313. The support sleeve 313 is driven to move during the movement of the support plate 2. The support sleeve 313 slides on the outer side of the support rod 311 and the slider 312 so that the support plate 2 can maintain balance and stability. A limiting ring 314 is fixed on the inner side of the bottom end of the support sleeve 313 to limit the relative position between the slider 312 and the support sleeve 313. There are four support rods 311, which are evenly distributed at the four corners of the upper surface of the base plate 1 to improve the stability of the bracket.

[0027] See also Figure 3-4 In order to improve the adaptability of the centrifuge tube holder to centrifuge tubes of different sizes, the clamping mechanism 4 in this embodiment includes a turning handle 401, which is rotatably connected to the right side of the support plate 2 through a bearing, and the left side of the turning handle 401 penetrates and extends to the inside of the support plate 2, and is fixed with a threaded rod 402, the turning handle 401 drives the threaded rod 402 to rotate, and the other end of the threaded rod 402 is rotatably connected to the left inner wall of the support plate 2 through a bearing, the outer side of the threaded rod 402 is threadedly connected to a threaded plate 403, the threaded rod 402 drives the threaded plate 403 to move, and the number of threaded plates 403 There are two threaded plates 403, and they are symmetrically distributed about the central axis of the threaded rod 402. A sliding rod 404 is fixed between the inner walls of the left and right sides of the support plate 2. The inner side of the threaded plate 403 is slidably connected to the outer side of the sliding rod 404. The sliding rod 404 can limit the angle of the threaded plate 403 to prevent the threaded plate 403 from being affected by the threaded rod 402 and causing the angle to shift. A clamping plate 405 is fixed to the right side of the threaded plate 403. The threaded plate 403 drives the clamping plate 405 to move. The clamping plate 405 can clamp and fix the outer side of the centrifuge tube body 6, thereby supporting centrifuge tubes of different sizes.

[0028] In this example, two threads in opposite directions are distributed on the outer side of the threaded rod 402 and are symmetrically distributed about the central axis of the threaded rod 402. Since bidirectional threads are provided on the outer side of the threaded rod 402, the two threaded plates 403 move relative to each other to clamp and support the centrifuge tube body 6 from both sides.

[0029] The working principle of the above embodiment is:

[0030] (1) When placing the centrifuge tube body 6, the position of the support plate 2 must first be adjusted according to the length of the centrifuge tube body 6 so that the centrifuge tube body 6 can be kept in a suitable position when placed. When adjusting the height of the support plate 2 upward, the support plate 2 only needs to be lifted from the bottom to the top, and the support plate 2 drives the rod sleeve 302 to move. The rod sleeve 302 slides on the outside of the positioning rod 301. When the rod sleeve 302 moves upward, the inner wall of the rod sleeve 302 squeezes the block 305 into the installation groove 303, so that the first spring 304 is compressed. When the slot 306 moves to the block 305, the first spring 304 bounces the block 305 into the slot 306. Since the left side of the block 305 is an upwardly inclined slope, the support plate 2 will not be hindered when moving upward. When adjusted to a suitable height, the block 305 bounces into the slot 306 at the corresponding position. At this time, the support plate 2 can continue to move upward but cannot move downward. When the centrifuge tube body 6 is placed, the centrifuge tube body 6 applies a downward force to the support plate 2 without causing a deviation in the position of the support plate 2.

[0031] (2) During the movement of the support plate 2, the support sleeve 313 is also driven to move. The support sleeve 313 slides on the outside of the support rod 311 and the slider 312 so that the support plate 2 can maintain balance and stability. When the position of the support plate 2 needs to be adjusted downward, the connecting plate 308 is pressed, and the connecting plate 308 drives the connecting rod 309 to move. The connecting rod 309 drives the push block 310 to move. The push block 310 pushes the block 305 inside the slot 306 out, so that the position of the rod sleeve 302 loses its fixing effect. At this time, the position of the rod sleeve 302 can be adjusted at will. After adjusting the height of the support plate 2, place the centrifuge tube body 6 into the placement hole 5, turn the handle 401, the handle 401 drives the threaded rod 402 to rotate, and the threaded rod 402 drives the threaded plate 403 to move. Since the outer side of the threaded rod 402 is provided with a bidirectional thread, the two threaded plates 403 move relative to each other, and the threaded plate 403 drives the clamping plate 405 to move. The clamping plate 405 can clamp and fix the outer side of the centrifuge tube body 6, thereby being able to support centrifuge tubes of different sizes.
