[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a seat back cable adjustment device, comprising a fixed shell 1, a conflict block 2 is fixedly connected to the inner wall of the fixed shell 1, a sleeve 3 is slidably connected inside the fixed shell 1, a conflict block 2 is fixedly connected to the lower surface of the sleeve 3, a reset assembly is arranged on the upper surface of the conflict block 24, a connecting column 6 is fixedly connected to the lower surface of the conflict block 24, a turntable 7 is fixedly connected to the lower surface of the connecting column 6, an adjustment shell 8 is rotatably connected to the outer wall of the turntable 7, the adjustment shell 8 is threadedly connected to the outer wall of the fixed shell 1, a shell 10 is fixedly connected to the upper surface of the fixed shell 1, and an adjustment bolt 9 is arranged on the outer wall of the shell 10; the reset assembly comprises a spring 5, one end of the spring 5 is fixedly connected to the upper surface of the conflict block 24, the other end of the spring 5 is fixedly connected to the lower surface of the conflict block 2, and the spring 5 is sleeved on the outer wall of the sleeve 3;

[0023] Specifically, first, the adjusting shell 8 plays a role in controlling the entire mechanism. By rotating the adjusting shell 8, the effect of driving the connecting column 6 on the upper surface of the rotating disk 7 to move can be achieved. This design makes the connecting column 6 a bridge between the rotating disk 7 and the abutment block 24, and further achieves the effect of facilitating the contraction of the spring 15. The abutment block 24 is connected to the connecting column 6, and when the connecting column 6 rises, the abutment block 24 will also rise. In this way, when the spring 15 contracts, the abutment block 24 will more easily push the spring 15, thereby achieving the effect of facilitating the contraction of the spring 15. After understanding the role of the abutment block 24, let's take a look at the role of the fixed shell 1. The fixed shell 1 tightly wraps the spring 15, and when the spring 15 contracts, the fixed shell 1 will also contract. In this way, the contraction of the fixed shell 1 drives the sleeve 3 to slide, and the sleeve 3 is realized. Smooth movement. Finally, the setting of the spring 15 solves the problem of excessive cable pressure during shaking. When the entire mechanism is shaken by external force, the spring 15 will undergo elastic deformation, thereby slowing down the shaking amplitude and reducing the pressure of the cable. In this way, the cable can remain relatively stable even in the case of severe shaking, thereby improving the durability of the entire mechanism.

[0024] Reference Figure 1 , Figure 2 and Figure 3, a sleeve 11 is fixedly connected to the lower surface of the turntable 7, and a fixing ring 13 is fixedly connected to the lower surface of the sleeve 11; a sliding ring 12 is slidably connected to the outer wall of the sleeve 11, and a plurality of connecting blocks 14 are fixedly connected to one side of the outer wall of the sliding ring 12; a telescopic rod 15 is fixedly connected to the lower surface of the connecting block 14, and the lower end of the telescopic rod 15 is fixedly connected to the upper surface of the fixing ring 13; a spring 2 16 is sleeved on the outer wall of the telescopic rod 15, and the upper end of the spring 2 16 is fixedly connected to the lower surface of the connecting block 14, and the lower end of the spring 2 16 is fixedly connected to the upper surface of the fixing ring 13; a plurality of connecting blocks 2 17 are fixedly connected to the outer wall of the sliding ring 12, and a mounting rod 18 is fixedly connected to the lower surface of the connecting block 2 17, and the mounting rod 18 is slidably connected to the inside of the fixing ring 13; a spring 3 19 is slidably connected to the inside of the mounting rod 18, and both ends of the spring 3 19 are fixedly connected to blocks 20, and the block 20 is slidably connected to the inside of the mounting rod 18;

[0025] Specifically, when the mounting rod 18 is inserted into the mounting area, the block 20 will be pushed by the spring three 19 and shrink. This design allows the block 20 to be quickly reset, thereby improving the efficiency of the operation. The spring three 19 and the spring two 16 are the power sources for driving the entire design movement. During the rapid reset of the block 20, the spring three 19 will be subjected to a reaction force, thereby pushing the connecting block one 14 to slide. This design allows the connecting block 14 to drive the sliding ring 12 to slide. The sliding ring 12 is another important component of the entire design. It realizes the sliding control of the mounting rod 18 by connecting with the mounting rod 18. When the connecting block 14 drives the sliding ring 12 to slide, the mounting rod 18 will also slide accordingly. Finally, when the mounting rod 18 moves to a suitable position, the block 20 will be stuck on the installed board, thereby achieving a fixing effect. This process benefits from the reaction force of the spring two 16, which enables the block 20 to be firmly fixed on the board.

[0026] Working principle: When the seat back cable is needed, the installation rod 18 is inserted into the installation area, and the spring three 19 is pushed to contract through the clamping block 20, so as to achieve the effect of driving the clamping block 20 to quickly reset. At this time, the reaction force of the spring two 16 pushes the connecting block 14 to slide, so as to achieve the effect of driving the sliding ring 12 to slide. At this time, the sliding ring 12 will drive the installation rod 18 to slide, so as to achieve the effect of driving the clamping block 20 to engage with the installation plate and achieve the fixation;

[0027] Secondly, when the tightness of the cable needs to be adjusted, the adjusting shell 8 is rotated to drive the connecting column 6 on the upper surface of the turntable 7 to move, and the connecting column 6 drives the resistance block 2 4, so as to facilitate the contraction of the spring 1 5. At this time, the contraction of the fixed shell 1 can drive the sleeve 3 to slide. The setting of the spring 1 5 can facilitate the reduction of excessive pressure on the cable caused by shaking.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
