[0022] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1

[0025] like Figure 1-4 As shown, the utility model provides a shock-absorbing base plate, including a base plate body 1, a support plate 2 and a mounting plate 3. A lifting plate 12 is arranged in the inner cavity of the base plate body 1. A fixing rod 121 is fixedly connected to the top of the lifting plate 12. The top of the fixing rod 121 passes through the support plate 2, and the top of the fixing rod 121 is fixedly connected to the bottom of the mounting plate 3. A sliding groove 11 is provided at the bottom of the inner cavity of the base plate body 1. A guide block 14 is slidably connected inside the sliding groove 11. An elastic steel plate 13 is fixedly connected to the bottom of the lifting plate 12. The bottoms of both ends of the elastic steel plate 13 are fixedly connected to the guide block 14. A damper 16 is arranged in the inner cavity of the base plate body 1. Both ends of the damper 16 are rotatably connected to mounting frames 15. Two limiting mechanisms 4 are installed in the inner cavity of the base plate body 1.

[0026] The limiting mechanism 4 includes a moving plate 41 and a linkage rod 43 . Both ends of the linkage rod 43 are rotatably connected to rotating frames 44 . One rotating frame 44 is fixedly connected to the bottom of the moving plate 41 , and the other rotating frame 44 is fixedly connected to the lifting plate 12 .

[0027] The following is a detailed description of the specific settings and functions of this embodiment. When the electromechanical equipment is installed on the top of the mounting plate 3, the mounting plate 3 will be pressed downward by its own weight, so that the mounting plate 3 drives the fixed plate and the lifting plate 12 to move downward. Then, the lifting plate 12 will use the rotating frame 44 on one side to move the linkage rod 43 downward together. At this time, since the movable plate 41 is installed on the top of the support plate 2, it can only move horizontally in a straight line. At this time, when the angle of the linkage rod 43 changes, under the limitation of the limit groove 21, the top rotating frame 44 is used to make the movable plate 41 start to move, and finally the two movable plates 41 are brought together, so as to complete the limitation of the electromechanical equipment and avoid sliding. In addition, the rubber block on one side of the positioning plate 42 can not only increase the friction between the electromechanical equipment and the positioning plate 42, but also prevent the excessive squeezing force when the positioning plate 42 is positioned to damage the electromechanical equipment.

[0028] During the movement, the vibration generated by the electromechanical equipment will cause the entire mounting plate 3 to shake, so that the mounting plate 3 will rise and fall due to the vibration. During this process, the damper 16 will expand and contract. During the expansion and contraction process, the damper 16 will squeeze the shock absorbing spring 17 on the surface, thereby cooperating with the energy absorption effect of the shock absorbing spring 17 and the damping force provided by the damper 16 to achieve a shock absorbing effect.

[0029] Embodiment 2

[0030] like Figure 2-4 As shown, the side wall of the support plate 2 is fixedly connected to the inner wall of the bottom plate body 1, and a groove is provided on the top of the support plate 2. The mounting plate 3 is located inside the groove, and the fixing rod 121 is slidably connected to the support plate 2. Limiting grooves 21 are provided on both sides of the support plate 2, and one of the rotating frames 44 is located inside the limiting groove 21. A positioning plate 42 is fixedly connected to one side of the moving plate 41. The top of one of the mounting frames 15 is fixedly connected to the bottom of the lifting plate 12, and the other mounting frame 15 is fixedly connected to the inner wall of the bottom plate body 1. A shock absorbing spring 17 is installed on the surface of the damper 16.

[0031] The effect achieved by the entire embodiment is that as the lifting plate 12 moves downward, it will squeeze the elastic steel plate 13, causing it to continue to bend. During this process, the guide blocks 14 connected to both ends of the elastic steel plate 13 will slide inside the sliding groove 11, which can limit the bending direction of the elastic steel plate 13 and avoid errors during the bending process.

[0032] Moreover, the guide block 14 inside the sliding groove 11 will consume the energy of the lifting plate 12 due to friction, thereby offsetting the energy during vibration to reduce the vibration amplitude, thereby protecting the mechanical equipment on the top of the mounting plate 3.

[0033] The usage and working principle of this device are as follows: First, the mounting holes on the surface of the mounting plate 3 facilitate the connection between the base of the electromechanical equipment and the mounting plate 3. As the electromechanical equipment runs, if strong vibrations occur, the mounting plate 3 will rise and fall inside the groove at the top of the support plate 2, and the mounting plate 3 will drive the fixing rod 121 to rise and fall together, so that during the lifting and lowering process of the lifting plate 12, the damper 16 will extend and retract, and can provide damping force, which can achieve a shock-absorbing effect in conjunction with the shock-absorbing spring 17.

[0034] In addition, when the lifting plate 12 is in the process of lifting, the elastic steel plate 13 will bend, so that the guide block 14 will slide inside the sliding groove 11. At this time, the friction between the guide block 14 and the inner wall of the sliding groove 11 is used to consume the energy in the vibration process, thereby reducing the vibration amplitude of the electromechanical equipment, so as to achieve the purpose of protecting the electromechanical equipment.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
