[0018] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0019] The components of the embodiments of the present invention generally described and shown in the drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Example

[0024] like Figure 1 and Figure 2 As shown, a rubber shear isolator proposed by the utility model includes a shell 1, a slide groove 11 is opened on one side of the shell 1, a mounting block 12 is slidably connected in the slide groove 11, and a U-shaped mounting plate 13 for connecting the device is installed at one end of the mounting block 12 away from the slide groove 11. When the device vibrates, the mounting block 12 is driven to slide in the slide groove 11 through the mounting plate 13.

[0025] For details, please refer to Figure 3The above-mentioned vibration isolator includes a buffer assembly 2 installed in the shell 1 for buffering vibration. The buffer assembly 2 includes a moving block 21, a first fixed plate 22, and a first friction block 23. The U-shaped moving block 21 is fixedly connected to the side of the mounting block 12 away from the mounting plate 13, and the moving block 21 moves synchronously with the mounting plate 13. The first fixed plate 22 is fixedly connected to the end of the moving block 21 away from the mounting block 12, and the first friction block 23 is installed on the side of the first fixed plate 22 away from the moving block 21. The first fixed plate 22 and the first friction block 23 also move synchronously with the mounting plate 13, so that when the mounting plate 13 vibrates, the first friction block 23 is driven to rub against the second friction block 31, thereby reducing the vibration amplitude and causing the first spring 26 to quickly stop reciprocating motion, thereby increasing structural stability. The buffer assembly 2 also includes a limit rod 24, a limit plate 25, and a first spring 26. Multiple groups of limit rods 24 are respectively installed on both sides of the moving block 21. When the moving block 21 moves, the limit rods 24 are driven to move synchronously. At the same time, the limit action of the limit rods 24 makes the moving block 21 move smoothly. The limit plate 25 is fixedly connected to one end of the limit rod 24 that passes through the shell 1. The limit plate 25 is used for limiting to prevent the moving distance from being too large. The first spring 26 sleeved on the limit rod 24 is set between the moving block 21 and the shell 1. The first spring 26 is used to be squeezed when the moving block 21 moves, so that the first spring 26 releases the elastic force to reset the moving block 21, which is used to absorb and store vibration energy.

[0026] Further, such as Figure 4As shown, the above-mentioned vibration isolator also includes a vibration reduction mechanism 3 arranged in the housing 1 to cooperate with the buffer assembly 2 to reduce the vibration amplitude. The vibration reduction mechanism 3 includes a second friction block 31 and a second fixed plate 32. The second friction block 31 is arranged on the side of the first friction block 23 away from the first fixed plate 22, so that the first friction block 23 can rub against the second friction block 31 when moving, so that the friction resistance prevents the reciprocating motion of the first spring 26, thereby achieving the purpose of reducing the vibration amplitude and preventing the conduction of vibration. The second fixed plate 32 is installed on the side of the second friction block 31 away from the first friction block 23, and the second fixed plate 32 is used to drive the second friction block 31 to approach the first friction block 23 to ensure friction. The vibration reduction mechanism 3 also includes a reinforcing rod 33, a limiting sleeve 34, and a positioning plate 35. Multiple groups of reinforcing rods 33 are fixedly connected to the side of the second fixed plate 32 away from the second friction block 31, and the reinforcing rods 33 move synchronously with the second fixed plate 32. Multiple groups of limiting sleeves 34 fixedly installed on the inner wall of the housing 1 are respectively slidably connected to the multiple groups of reinforcing rods 33, so that the movement of the second fixed plate 32 is stable. The positioning plate 35 fixedly connected in the housing 1 is slidably connected with the plurality of reinforcing rods 33, further limiting the movement of the second fixed plate 32, making it move smoothly and keep its position stable, and not easily affected by the friction of the first friction block 23 to cause displacement. The damping mechanism 3 also includes a fixed cylinder 36, a sliding plate 37, a connecting rod 38, and a second spring 39. The plurality of fixed cylinders 36 are all installed on the side of the positioning plate 35 close to the second fixed plate 32, and the position of the fixed cylinder 36 is fixed. The sliding plate 37 is slidably connected in the fixed cylinder 36, one end of the connecting rod 38 slidably connected in the fixed cylinder 36 is fixedly connected to the sliding plate 37, and the other end of the fixed cylinder 36 is fixedly connected to the side of the second fixed plate 32. The second spring 39 is arranged in the fixed cylinder 36 and is located on the side of the sliding plate 37 away from the connecting rod 38, and is used for the second spring 39 to push the second fixed plate 32 when releasing the elastic force, so that the second friction block 31 is close to the first friction block 23, and even after wear, sufficient friction can still be guaranteed to balance the deformation of the first spring 26.

[0027] In this embodiment, the device is installed on the mounting plate 13, and the position of the housing 1 is fixed by fasteners. When the device vibrates, the mounting plate 13 is driven to move, and at the same time, the moving block 21 moves and squeezes the multiple groups of first springs 26 on both sides. The first springs 26 release energy after being squeezed, and the first springs 26 release elastic force when the moving block 21 moves away. At this time, the moving block 21 is driven to reciprocate, which increases the vibration amplitude. At the same time, when the moving block 21 moves, the first friction block 23 and the second friction block 31 are driven to rub against each other, slowing down the speed and amplitude of the vibration of the moving block 21, and improving the stability and safety of the system. At the same time, the elastic force of the second spring 39 can make the second friction block 31 always close to the first friction block 23, so that even if the contact surface of the first friction block 23 and the second friction block 31 is worn, a certain friction force can still be guaranteed.

[0028] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
