[0002]
Traditional stoppers used in rail vehicles and other equipment are generally rubber stoppers with a single material and limited cushioning stopper performance
Moreover, based on the characteristics of the rubber material, its stiffness and compression distance can only present a single nonlinear curve (compression stiffness curve). The adjustment of the compression stiffness curve can only be achieved by changing the type of rubber material, and the adjustment range is limited.

Embodiment Construction
[0027] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0028] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a specific embodiment of the stop device provided by the present invention.
[0029] Such as figure 1 As shown, the present invention provides a stop device, which is arranged between the component to be installed 7 and the component to be stopped 8 . In detail, the stop device can be installed on the component to be installed 7 , and can stop the component to be stopped 8 , so as to prevent the component to be stopped 8 from directly colliding with the component to be installed 7 .
[0030] Here, the embodiment of the present invention does not limit the specific types of the component to be installed 7 and the component to be stopped 8...

The invention discloses a stop device which comprises a mounting seat and a stop cap made of rubber, the stop cap is connected with the mounting seat to define a closed containing cavity, and the containing cavity is filled with a fluid medium; the buffer cylinder and the elastic piece are arranged in the containing cavity, the buffer cylinder comprises a cylinder body and a piston, the piston is provided with a damping hole and connected with the elastic piece, one of the cylinder body and the elastic piece acts with the stop cap, and the elastic piece is connected with the damping hole. And the other one of the cylinder body and the elastic piece acts with the mounting seat. The backstop device has better buffering and backstop performance, is more convenient to adjust, and can conveniently form compression stiffness curves with more shapes so as to better meet the use requirements.
Description
technical field [0001] The invention relates to the technical field of stop structures, in particular to a stop device. Background technique [0002] Traditional stoppers used in rail vehicles and other equipment are generally rubber stoppers with a single material and limited cushioning stopper performance. Moreover, based on the characteristics of the rubber material, its stiffness and compression distance can only present a single nonlinear curve (compression stiffness curve). The adjustment of the compression stiffness curve can only be realized by changing the type of rubber material, and the adjustment range is limited. Contents of the invention [0003] The purpose of the present invention is to provide a stop device with better buffer stop performance, which is easier to adjust, and can conveniently form more compression stiffness curves in various shapes to better meet the use requirements. [0004] In order to solve the above technical problems, the present inve...
