Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-4 , the present invention provides a technical solution for a speed measurement auxiliary device for a closed centrifuge: including: an auxiliary cover plate 1, an observation hole 11 opened on the upper surface of the auxiliary cover plate 1, and support plates 12 symmetrically installed on the lower surface of the auxiliary cover plate 1. Moving plates 4 are symmetrically and slidably installed on the lower surface of the auxiliary cover plate 1. A connecting plate 41 is connected to the lower surface of the moving plate 4. A lifting plate 42 is arranged outside the connecting plate 41. A fixed plate 43 is fixed to one side of the lifting plate 42. Moving grooves 131 are also symmetrically opened on the lower surface of the auxiliary cover plate 1. A double-headed motor 13 is installed inside the moving groove 131. A screw 132 is connected to the driving end of the double-headed motor 13. This setting makes the screw 132 rotate by the operation of the double-headed motor 13, and then the distance between the two lifting plates 42 can be adjusted to achieve the purpose of positioning the centrifuge. And the centrifuge can be pressed under the auxiliary cover plate 1 through the fixed plate 43 to achieve the purpose of fixing the centrifuge.

[0023] At the end face position of the upper surface of the auxiliary cover plate 1, a placement box 3 is installed. A placement groove 31 is opened on the upper surface of the placement box 3. A partition plate 32 is slidably installed inside the placement groove 31. This setting uses the placement box 3 to place the disassembled centrifuge lid, and disassembling tools can also be placed inside the placement groove 31, facilitating subsequent speed measurement work.

[0024] As Figure 1 shown, a bracket 2 is also installed on the upper surface of the auxiliary cover plate 1 behind the observation hole 11. A speedometer 21 is installed on the lower surface of the bracket 2 above the observation hole 11. This setting uses the speedometer 21 to perform speed measurement work on the fixed centrifuge.

[0025] As Figure 1 、 Figure 3 and Figure 4 shown, a moving block 44 is installed on the upper surface of the moving plate 4. The moving block 44 is slidably arranged inside the moving groove 131 and outside the screw rod 132. A threaded hole 441 is opened on one side of the moving block 44. A bearing 133 is installed inside the moving groove 131. One end of the screw rod 132 penetrates inside the threaded hole 441 and is embedded inside the bearing 133 and rotatably connected to the bearing 133. This setting uses the operation of the double-headed motor 13 to cause the screw rod 132 to rotate, and then the moving block 44 can move inside the moving groove 131 to adjust the distance between the two lifting plates 42, so as to meet the placement of centrifuges of different sizes.

[0026] As Figure 3 shown, the lifting plate 42 and the fixing plate 43 are arranged in an "L" shape, and a fixing groove 421 is opened inside the lifting plate 42. Electric telescopic rods 422 are symmetrically arranged inside the fixing groove 421. The telescopic ends of the electric telescopic rods 422 are connected to the lower surface of the connecting plate 41. This setting uses the operation of the electric telescopic rods 422 to cause the lifting plate 42 to move, and then the centrifuge on the fixing plate 43 can be moved upward to contact the auxiliary cover plate 1 to achieve the purpose of positioning.

[0027] As Figure 2 shown, guide blocks 33 are symmetrically arranged on both sides of the partition plate 32. Guide grooves 331 that slide with the partition plate 32 are opened inside the placement box 3. This setting uses the guide blocks 33 to slide inside the guide grooves 331 to adjust the position of the partition plate 32, so as to facilitate the placement of different items for the purpose of disassembling the centrifuge lid.

[0028] The working principle of the present utility model is as follows: When the speed measurement auxiliary device of the closed centrifuge of the present utility model is in use, first, the tool for disassembling the centrifuge cover can be taken out from the interior of the placement box 3. After taking it out, the centrifuge cover is disassembled. After disassembly, the auxiliary cover plate 1 is covered on the centrifuge. The operation of the double-headed motor 13 will cause the screw rod 132 to rotate, which will cause the moving block 44 to move inside the moving groove 131. Furthermore, the moving plate 4 can be moved to adjust the distance between the two lifting plates 42. In this way, the bottom of the centrifuge can be set on the fixed plate 43. At the same time, after placement, the operation of starting the electric telescopic rod 422 will cause the lifting plate 42 to lift and lower. Furthermore, the top of the centrifuge can be made to contact the lower surface of the auxiliary cover plate 1. In this way, the speed measurement work can be carried out through the speedometer 21 through the observation hole 11. The size of the observation hole 11 can be opened according to actual needs.

[0029] The above is only the preferred implementation mode of the present utility model. It should be pointed out that for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model, without special instructions and limitations, are implemented according to the conventional means in this field.
