Embodiment Construction

[0040] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0041] The structure of the cable stroke adjustment mechanism provided by the embodiment of the present invention is as follows: figure 2 As shown, it is installed between the first section of the cable 11 and the second section of the cable 12, including the first base 5, the second base 6, the first slider 7, the second slider 8 and the first spring 9 and the second Two springs 10.

[0042] Wherein, the first base 5 is cylindrical, such as image 3 and Figure 5 As shown, a bottom end 501 and a second end 503 are included. The bottom end 501 of the first base 5 is provided with a cable installation hole 502 , preferably, the hole 502 is located at the center of the bottom end 501 . A scale line 504 is marked on the outer wall of the second end 503 of the first base 5 , and an annular locking groove 505 for docking with the second base 6 is provi...

Abstract

The present invention relates to a cable stroke adjustment mechanism, which is applicable for solving the following problem that: cable stroke changes affect displacement transfer by a cable system. The cable stroke adjustment mechanism comprises a first base, a second base, a first sliding block, a second sliding block and a first spring, wherein the first base and the second base are connected, and can relatively rotate along a circumferential direction, the first sliding block is arranged inside the first base and can only slide along an axial line direction of the first base, the second sliding block is arranged inside the second base and can only slide along an axial line direction of the second base, the first sliding block and the second sliding block are connected and can relatively rotate along a circumferential direction so as to adjust a length of a connection part between the two sliding blocks, and the first spring is arranged between the first base and the bottom surface of the first sliding block. According to the present invention, with rotations of the first base and the second base, a distance between the first sliding block and the second sliding block can be changed so as to tighten or release the cable, adjust a cable stroke, and solve a problem of implementing mechanism function failure caused by the cable stroke change.

Description

technical field [0001] The invention relates to a cable stroke adjustment mechanism. Background technique [0002] The cable system is a widely used mechanical transmission system, and its main function is to transmit the operating force and displacement of the operating mechanism to the actuator. Generally speaking, the stroke of the operating mechanism is a fixed value, while the stroke of the cable changes with the direction of the cable. Once the change of the stroke of the cable exceeds the tolerance allowed by the system, it will affect the operation force and the force of the cable system. The transmission of the displacement will affect the normal work of the actuator, and in severe cases, it will cause the function of the actuator to fail. [0003] The structure at one end of the traditional cable is as Figure 1a As shown, it is mainly composed of steel wire 1 and casing 2. like Figure 1b As shown, the steel wire 1 is connected to the unlocking lever 3 inside t...
