[0020] An elevator cable winding device, referring to Figure 1-Figure 2 , including a mounting base 1, one end of the mounting base 1 is provided with a winding reel 2 for winding up the cable, and the other end is provided with a guide assembly, the guide assembly is provided with an opening 3 for limiting the free end of the cable, the mounting base 1 is provided with a movable groove 4, and a plurality of steel balls 5 are rollingly set on the side walls of the movable groove 4, and the two sides of the guide assembly are respectively connected with connecting pieces, and limiting grooves 6 are respectively provided on both sides of the movable groove 4. The connecting pieces are movably connected to the corresponding limiting grooves 6, and the guide assembly realizes rolling cooperation with the movable groove 4 through the steel balls 5 under the action of external force, while driving the connecting piece to move in the limiting groove 6.

[0021] Furthermore, the connecting member includes an L-shaped rod 71 , one end of the L-shaped rod 71 is connected to the guide assembly, and the other end passes through the limiting slot 6 and is connected to the limiting block 72 .

[0022] Furthermore, the longitudinal section of the movable groove 4 is a U-shaped structure.

[0023] Furthermore, the guide assembly includes a linkage seat 81 that rolls with the movable groove 4, a guide platform 82 is provided on the linkage seat 81, a spring 83 is provided between the guide platform 82 and the linkage seat 81, the opening 3 is provided on the guide platform 82, and a pressure plate 84 for tightening the cable is provided on the guide platform 82.

[0024] Furthermore, the movable groove 4 is an arc-shaped groove.

[0025] The working principle of this utility model is:

[0026] As Example 1, the cable is wound on the reel 2 so that the free end of the cable passes through the opening 3 on the guide platform 82. When the cable is not needed, the pressure plate 84 is pressed on the lower end of the cable to prevent the cable from becoming loose. When the cable needs to be taken, the free end of the cable is pulled downward. Since the free end of the cable passes through the opening 3 on the guide platform 82 and can limit the free end, and a spring 83 is provided between the guide platform 82 and the linkage seat 81, the guide platform 82 will move downward to squeeze the spring 83, and the pressure plate 84 is connected to the guide platform 82, so it will drive the pressure plate 84 to move downward, and the staff can pull the cable out to a certain length. Due to different installation scenarios, when the position of the wiring to be wired changes, the relative position between the guide platform 82 and the mounting seat 1 needs to be changed. This part is the main design concept of this application, so this part will be described in detail:

[0027] When the free end of the cable is pulled toward the designated position, the guide platform 82, the linkage seat 81, the spring 83, and the pressure plate 84 will move synchronously. The lower end of the linkage seat 81 extends into the movable groove 4 and realizes rolling cooperation with the steel ball 5. Figure 2 It can be seen that when the lower end of the linkage seat 81 moves in the movable groove 4, the presence of the steel ball 5 enables the lower end of the linkage seat 81 to achieve rolling cooperation with the movable groove 4. The linkage seat 81 is connected to the lower end of the guide platform 82, and connecting pieces are respectively provided on both sides of the guide platform 82, so that the connecting pieces will be driven to move synchronously in the limit groove 6. Compared with the sliding friction between the sliding block and the movable groove 4 in the prior art, the present application achieves rolling cooperation between the linkage seat 81 and the movable groove 4 through the steel ball 5, which reduces the wear on the movable groove 4 and avoids the phenomenon of jamming during movement. In order to prevent the linkage seat 81 from shaking during movement, the present application also provides connecting pieces on both sides of the guide platform 82. When the guide platform 82 moves, the setting of the connecting pieces has a balancing effect on the movement of the guide platform 82, preventing the guide platform 82 from shaking during movement. The connecting member can be configured as an L-shaped rod 71, one end of which passes through the limiting groove 6 and is connected to the limiting block 72. The setting of the limiting block 72 can prevent the L-shaped material from falling out of the limiting groove 6 during movement. The steel ball 5 mentioned above can be provided with multiple mounting holes on the side wall of the movable groove 4, each mounting hole is provided with a fixing column, and the steel ball 5 is rotatably mounted on the fixing column. There are many ways to set the steel ball 5, as long as it can ensure that the linkage seat 81 can achieve rolling cooperation with the steel ball 5 when moving in the movable groove 4.

[0028] In the above technical solution, if Figure 1 As shown in Example 2, the movable groove 4 takes an arc groove as an example, and the linkage seat 81 and the connecting member and other structures are as shown in FIG. Figure 1As shown in the assembly, when the cable is pulled, the linkage seat 81 provided at the lower end of the guide platform 82 can move along the arc groove, and the connecting piece also moves along with the limit groove 6, and the structure of the limit groove 6 here also needs to be set to an arc structure; compared with the movement of the universal wheel in the arc groove in the prior art, the prior art will have a jamming phenomenon; the connecting pieces provided on both sides of the guide platform 82 in the present application have a directional effect on the moving trajectory of the guide platform 82, and the linkage seat 81 is achieved by the steel ball 5 to achieve rolling cooperation with the arc groove, so the guide platform 82 can move smoothly and will not get stuck.

[0029] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the present invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to illustrate rather than limit the present invention, which shall be defined by the claims.
