[0030] Please refer to Figure 1-4 , an embodiment provided by the present utility model:

[0031] A desktop high-speed centrifuge, which includes:

[0032] A centrifuge body 1, a support plate 2 is fixedly installed on the bottom surface of the centrifuge body 1. The bottom of the support plate 2 penetrates through a limit window 3. The support plates 2 are symmetrically distributed with respect to the centrifuge body 1. The support plate 2 is slidably connected to the limit window 3. The above structural design enables the centrifuge body 1 to drive the support plate 2 to move stably and linearly along the limit window 3, facilitating the normal operation of the vertical shock protection structure. The limit window 3 is penetrated and opened on the bottom surface of the base 4. A bottom buffer spring 5 is fixed on the top surface of the horizontal part at the bottom end of the support plate 2. The top end of the bottom buffer spring 5 is connected and fixed to the bottom surface of the base 4. The front view shape of the support plate 2 is "丄"-shaped. The bottom buffer springs 5 are symmetrically and vertically installed at the bottom of the support plate 2. The above structural design enables the bottom buffer spring 5 to be stably installed and utilizes the elasticity of the bottom buffer spring 5 itself to perform buffer protection on the centrifuge body 1 in the vertical direction;

[0033] A support plate 2, one side of the support plate 2 is connected to one side of a gear cylinder 6. The gear cylinder 6 is rotatably connected to the inner wall of the base 4 through the middle shafts 7 on both sides. A scroll spring 8 is fixed on the side surface of the gear cylinder 6. The end of the scroll spring 8 is connected and fixed to the inner wall of the base 4. The top end of the gear cylinder 6 is connected to the bottom surface of a horizontal plate 9;

[0034] A horizontal plate 9 is provided with a stabilizing hole 10 at the center thereof, a horizontal rod 11 is installed through the stabilizing hole 10, one end of the horizontal rod 11 is connected and fixed to the inner wall of the base 4, and the other end of the horizontal rod 11 is connected and fixed to the top of the base plate 12, a horizontal buffer spring 13 is fixed to one side of the horizontal plate 9, and the end of the horizontal buffer spring 13 is fixed to the top of the base plate 12, a top plate 14 is fixed to one end of the top surface of the horizontal plate 9, and a positioning column 15 is installed on the top of the top plate 14.

[0035] In one embodiment, a cooling fan 16 is installed through the center of the bottom surface of the base 4, and the distance between the top surface of the cooling fan 16 and the bottom surface of the centrifuge body 1 is greater than half of the inner height of the base 4. The above structural design can effectively heat the centrifuge body 1 from the bottom.

[0036] In one of the preferred embodiments, the gear barrel 6 is meshingly connected with the toothed structures densely arranged on the side of the support plate 2 and the toothed structures densely arranged on the bottom of the horizontal plate 9. The center of the gear barrel 6 and the center of the horizontal plate 9 are on the same vertical plane. The above-mentioned structural design enables the support plate 2 to drive the gear barrel 6 to rotate by utilizing the threaded connection relationship when it moves in the vertical direction. The gear barrel 6 can also drive the horizontal plate 9 to move horizontally by utilizing the threaded connection relationship, which facilitates the cooperation between the vortex spring 8 and the horizontal buffer spring 13 to perform multi-stage buffer protection.

[0037] In one embodiment, the horizontal plate 9 is provided with stabilizing holes 10 at equal intervals, and the stabilizing holes 10 are slidably connected to the horizontal rod 11. The above structural design enables the horizontal plate 9 to move stably horizontally and linearly along the horizontal rod 11 with the stabilizing holes 10.

[0038] In one of the preferred embodiments, the material of the positioning column 15 is rubber, and the positioning column 15 is densely arranged at equal intervals on the top of the side of the top plate 14. The length of the top plate 14 is equal to the length of the horizontal plate 9, and the length of the horizontal plate 9 is greater than half of the side length of the base 4. The above-mentioned structural design enables the positioning column 15 to stably fit with the bottom of the side of the centrifuge body 1 when following the movement of the top plate 14 and the horizontal plate 9, thereby locking and protecting the centrifuge body 1.

[0039] The working principle of the utility model is as follows: when the centrifuge body 1 generates vibration during normal operation, the centrifuge body 1 and the support plate 2 slide vertically down along the limit window 3, the bottom buffer spring 5 is stretched, and the elastic force of the bottom buffer spring 5 can offset part of the vibration;

[0040] When the support plate 2 moves downward, the threaded connection is used to drive the gear cylinder 6 to rotate, and the vortex springs 8 at both ends of the gear cylinder 6 are squeezed and rolled up. The elastic force of the vortex springs 8 prevents the gear cylinder 6 from continuing to rotate. The gear cylinder 6 then applies this force to the support plate 2, further preventing the support plate 2 from moving vertically, and cooperates with the bottom buffer spring 5 to play a buffering role;

[0041] While the gear barrel 6 is rotating, the threaded connection relationship is used to drive the horizontal plate 9 with the stabilizing hole 10 to slide horizontally along the horizontal rod 11 and squeeze the horizontal buffer spring 13, and the horizontal buffer spring 13 is used for buffering again. When the horizontal plate 9 moves horizontally, it drives the top plate 14 and the positioning column 15 to move horizontally synchronously close to the centrifuge body 1. The positioning column 15 made of rubber material directly fits the bottom of the side of the centrifuge body 1 to squeeze and limit the centrifuge body 1, further limiting the vertical and horizontal vibration of the centrifuge body 1, and achieving a better buffer protection effect. At the same time, the cooling fan 16 works to efficiently dissipate heat from the bottom of the centrifuge body 1.

[0042] The above is only an embodiment of the utility model, and the common sense such as the known specific structure and characteristics in the scheme is not described too much here. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and the utility model can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims in the utility model. Any figure mark in the claims should not be regarded as limiting the claims involved.
