[0002] Tensile and tear-resistant bushings are applicable to various mechanical structures that need to withstand tensile and tearing forces, such as in the fields of automobiles, aerospace, and construction machinery, etc., to improve the reliability and service life of equipment.

[0003] Currently, in the field of mechanical engineering, in order to improve the strength and durability of structures, various bushings are usually used to enhance the bearing capacity of key parts, providing important protection for mechanical equipment, thereby extending the service life of the equipment.

[0004] When the tensile and tear-resistant bushing is used, it is used to enhance key parts in the mechanical structure. By means of the bushing, it is convenient to protect these key parts, facilitate the durable use of the mechanical structure, and reduce the damage of key parts. However, when fixing the rubber block of the existing bushing, most of them use glue or the pressing restriction of external equipment. When the bushing is in use, it is easy for the bushing to deform and the rubber to fall off under the action of external force, which will easily affect the operation and service life of the bushing and is not convenient for the use of the bushing. Summary of the Utility Model

[0005] The purpose of this application is to solve the problem that when fixing the rubber block of the existing bushing, most of them use glue or the pressing restriction of external equipment. When the bushing is in use, it is easy for the bushing to deform and the rubber to fall off under the action of external force, which will easily affect the operation and service life of the bushing and is not convenient for the use of the bushing. This application provides a tensile and tear-resistant bushing.

A buffer layer is fixed to the side of the connecting layer away from the housing. A restricting layer is fixed to the side of the buffer layer away from the connecting layer. Fixing grooves are formed on the surface of the housing, and the fixing grooves are distributed in an array. A restricting mechanism is arranged between the housing and the restricting layer.

[0008] By adopting the above technical solution, the restriction and fixation of the rubber block in the bushing are increased through the restricting mechanism, reducing the situation of the rubber block falling off when the bushing is deformed by external force, reducing the influence on the operation and service life of the bushing, and facilitating the use of the bushing.

[0009] Furthermore, the limiting mechanism includes a plurality of limiting columns slidably arranged in the shell, a spring is fixed to one end of the limiting column, a limiting groove is opened in the limiting layer corresponding to the position of the limiting column, the limiting column extends out of the shell and into the limiting groove, and a limiting component is arranged between the limiting column and the shell.

[0010] By adopting the above technical solution, the elasticity of the spring enables the limiting column to move, and the limiting column moves into the limiting groove to limit the limiting layer.

[0012] By adopting the above technical solution, the limiting column slides on the sliding column to limit the limiting column, and then the pad block is opened, and the rotating column is twisted by a tool, and the rotating column moves in the shell, so that the rotating column drives the moving block to move, and the moving block drives the spring to expand and contract, and the length of the spring is adjusted to make the limiting column slide on the sliding column, which is convenient for adjusting the resistance force to the limiting layer.

[0013] Furthermore, the shell is made of polyurethane material, and the shell corresponds to the connecting layer.

[0015] Furthermore, the connection layer is made of a high-strength fiber woven mesh material and is staggeredly distributed, and the connection layer is in a grid shape.

[0016] By adopting the above technical solution, a high-strength fiber woven mesh is staggered into a grid shape, which facilitates improving the tensile and tear resistance of the bushing.

[0017] Furthermore, the buffer layer is made of polyurethane foam material, and the buffer layer corresponds to the connecting layer.

[0018] By adopting the above technical solution, the buffer layer is made of polyurethane foam material, which is convenient for absorbing impact and vibration energy and protecting the buffer layer from damage.

[0019] Furthermore, the restriction layer is made of high-elastic rubber material.

[0021] Furthermore, a fixed lubricant is provided in each of the fixing grooves.

[0022] By adopting the above technical solution, the fixed lubricant in the fixed groove can reduce friction resistance, improve the sliding performance of the bushing, and provide additional lubrication protection in harsh environments.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. When the tensile and tear-resistant bushing is in use, the elasticity of the spring causes the limiting column to move, and the limiting column moves into the limiting groove to limit the limiting layer, thereby reducing the movement of the limiting layer. At the same time, the limiting column slides on the sliding column to limit the limiting column, and then the pad is opened, and the rotating column is twisted by a tool, and the rotating column moves in the shell, so that the rotating column drives the moving block to move, and the moving block drives the spring to expand and contract, and the length of the spring is adjusted to make the limiting column slide on the sliding column, which is convenient for adjusting the resistance to the limiting layer. The limiting mechanism is used to increase the restriction and fixation of the rubber block in the bushing, thereby reducing the possibility of the rubber block falling off when the bushing is deformed by external force, reducing the impact on the operation and service life of the bushing, and facilitating the use of the bushing.

When the tensile and tear-resistant bushing is in use, the shell is made of polyurethane, which is convenient for protecting the connecting layer and the buffer layer and improving the overall durability of the bushing. The connecting layer adopts a high-strength fiber woven mesh and is staggered into a grid shape to improve the tensile and tear-resistant properties of the bushing.
