Columns are symmetrically and fixedly installed at the bottom of the four sides of the plate centrifuge body. A base is installed below the plate centrifuge body. Sleeves are fixedly installed at the four corners of the top of the base corresponding to the positions of the columns. The columns are movably installed inside the sleeves. A four-way shock-absorbing component for four-way shock-absorbing of the plate centrifuge body is installed between the outer side of the bottom of the columns and the sleeves. A vertical shock-absorbing component for vertical shock-absorbing of the plate centrifuge body is installed at the bottom end of the plate centrifuge body.

Meanwhile, through the operation of the second damper, the vertical direction of the flat centrifuge body is reset, which is used for shock absorption in different directions of the flat centrifuge body. Compared with the prior art, the shock absorption effect is improved.
[0013] () In the utility model, the flat centrifuge body is connected to the heavy object through a pull rope. Due to the inertia of the heavy object, a reverse pulling force is provided in the vibration direction of the flat centrifuge body to slow down the vibration of the flat centrifuge body.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.
[0020] The present utility model provides the following technical solutions: As Figures 1 to 4 shown, in this embodiment, a centrifuge with a shock-absorbing structure includes a flat centrifuge body 1. Four columns 2 are symmetrically and fixedly installed at the bottom of the four sides of the flat centrifuge body 1. A base 3 is installed below the flat centrifuge body 1. Sleeves 4 are fixedly installed at the four corners of the top of the base 3 corresponding to the positions of the columns 2. The columns 2 can be movably installed inside the sleeves 4. A four-way shock-absorbing component for four-way shock absorption of the flat centrifuge body 1 is installed between the outer side of the bottom of the columns 2 and the sleeves 4. A vertical shock-absorbing component for vertical shock absorption of the flat centrifuge body 1 is installed at the bottom end of the flat centrifuge body 1. A heavy object 5 is fixedly installed at the bottom end of the flat centrifuge body 1 through a pull rope.
[0021] As Figures 1 to 4 shown, the four-way shock-absorbing component includes a first damper 6. The first damper 6 is fixedly installed in an annular array on the outer side of the bottom of the column 2 with the central axis of the column 2 as the axis.
[0022] When the flat centrifuge body 1 is in use, the flat centrifuge body 1 will generate shock. During vibration, the column 2 will shake inside the sleeve 4. At this time, the inner wall of the sleeve 4 will be squeezed by the first dampers 6 at different positions on the four columns 2 to perform shock absorption and reset for the horizontal plane of the column 2.
[0023] As Figures 1 to 4 shown, a ball 7 is rotatably installed at one end of the first damper 6 away from the column 2.
[0024] When the first damper 6 squeezes the inner wall of the sleeve 4, the contact between the first damper 6 and the sleeve 4 is transmitted through the ball 7, ensuring the stability of the contact between the first damper 6 and the sleeve 4 when the first damper 6 shakes inside the sleeve 4.
[0025] As Figures 1 to 4 shown, the vertical shock-absorbing component includes a mounting ring 8, a shock-absorbing spring 9, and a second damper 10. The mounting ring 8 is fixedly installed at the bottom end of the column 2. The shock-absorbing spring 9 is fixedly installed in an annular array on the lower surface of the mounting ring 8 with the central axis of the mounting ring 8 as the axis. The second damper 10 is fixedly installed at the bottom of the column 2.
[0026] The vertical vibration of the flat centrifuge body 1 is shock-absorbed by the shock-absorbing spring 9. At the same time, the vertical reset of the flat centrifuge body 1 is performed through the operation of the second damper 10.
[0027] AsFigures 1 to 4 As shown, on the outer ring of the mounting ring 8, sliding holes 11 are annularly and arrayedly formed with the central axis of the mounting ring 8 as the axis. A sliding rod 12 is slidably installed inside the sliding hole 11. A fixing ring 13 is installed at the bottom of the four sliding rods 12. The second damper 10 is fixedly installed between the fixing ring 13 and the column 2. The shock-absorbing spring 9 is sleeved outside the sliding rod 12.
[0028] When the column 2 shakes inside the sleeve 4, the mounting ring 8 will move along with the movement of the column 2. The connection of the mounting ring 8 by the sliding rod 12 will drive the shock-absorbing spring 9 to move synchronously, so as to ensure the stability of the shock-absorbing spring 9 and prevent it from bending.
[0029] As Figures 1 to 4 shown, on the upper surface of the base 3, mounting blocks 14 are fixedly installed annularly and arrayedly with the central axis of the base 3 as the axis. An elastic pull rope 15 is fixedly installed between one side of the mounting block 14 and the heavy object 5.
[0030] When the flat centrifuge body 1 generates shock absorption, the flat centrifuge body 1 is connected to the heavy object 5 through a pull rope. Due to the inertia of the heavy object 5, a reverse pulling force will be provided in the vibration direction of the flat centrifuge body 1 to slow down the vibration of the flat centrifuge body 1. The pulling of the four elastic pull ropes 15 will drive the heavy object 5 to reset, so as to further shock-absorb the flat centrifuge body 1 and improve the stability of the flat centrifuge body 1.
[0031] The present utility model provides a centrifuge with a shock-absorbing structure, and the specific working principle is as follows:
[0032] When the flat centrifuge body 1 is in use, the flat centrifuge body 1 will generate shock absorption. During vibration, the column 2 will shake inside the sleeve 4. At this time, the first dampers 6 at different positions on the four columns 2 will squeeze the inner wall of the sleeve 4 to shock-absorb and reset the horizontal plane of the column 2. At the same time, when the flat centrifuge body 1 vibrates vertically, the shock-absorbing spring 9 on the mounting ring 8 at the bottom of the column 2 will shock-absorb the vertical vibration of the flat centrifuge body 1. Meanwhile, through the operation of the second damper 10, the vertical direction of the flat centrifuge body 1 will be reset, so as to shock-absorb different orientations of the flat centrifuge body 1. Compared with the prior art, the shock-absorbing effect is improved;
[0033] When the flat centrifuge body 1 generates shock absorption, the flat centrifuge body 1 is connected to the heavy object 5 through a pull rope. Due to the inertia of the heavy object 5, a reverse pulling force will be provided in the vibration direction of the flat centrifuge body 1 to slow down the vibration of the flat centrifuge body 1. The pulling of the four elastic pull ropes 15 will drive the heavy object 5 to reset, so as to further shock-absorb the flat centrifuge body 1 and improve the stability of the flat centrifuge body 1.
[0034] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
