[0021] Example 1

[0022] In this embodiment, as Figures 1 to 3 As shown, a cable winding and unwinding device 10 is provided, including a mounting base 100, a winding structure 200, and a fixing seat 300. The winding structure 200 and the fixing seat 300 are mounted on the mounting base 100. The winding structure 200 is used to wind and unwind the cable, and the fixing seat 300 is used to fix the beginning of the cable to prevent the cable from becoming loose due to its own weight when not in use.

[0023] In one of the embodiments, the mounting base 100 comprises a first side plate 101 and a second side plate 102 arranged along a height direction, and a bottom plate 103 connecting the first side plate 101 and the second side plate 102 transversely, and the fixing seat 300 is mounted on the bottom plate 102.

[0024] In one of the embodiments, the bottom of the bottom plate 103 is further provided with a roller, which facilitates the movement of the cable winding and unwinding device 10.

[0025] Specifically, referring to Figure 3 As shown in the drawings, the fixing seat 300 is fixedly arranged on the mounting base 100, the fixing seat 300 is provided with a positioning hole 301 along a first direction, and the positioning hole 302 is used for arranging the cable, the side wall of the positioning hole 301 is provided with a limiting hole 302, the limiting hole 302 is movably arranged with a limiting block 303 along the opening direction of the limiting hole 302, the limiting block 303 is provided with a through hole 304 along the first direction, the limiting block 303 is used for arranging the initial end of the cable to pass through the through hole 304 when the through hole 304 is aligned with the positioning hole 301, and the cable in the through hole 304 is bent along the movement direction of the limiting block 303 when the through hole 304 is misaligned with the positioning hole 301, so that the initial end of the cable is fixed between the through hole 304 and the positioning hole 301.

[0026] In the embodiment, the fixing seat 300 is arranged to fix the initial end of the cable, the misalignment of the through hole 304 and the positioning hole 301 is driven by the movement of the limiting block 303, the cable in the through hole 304 is bent along the movement direction of the limiting block 303, the initial end of the cable in the through hole 304 and the positioning hole 301 on both sides of the through hole 304 is bent into an S shape, and the fixation of the initial end of the cable is realized, so that the initial end of the cable is prevented from moving to cause the cable to be loose when not in use, and the technical problem of the loose cable caused by the rotation of the cable due to its own weight after the winding of the existing winding and unwinding device is solved.

[0027] In one of the embodiments, the first direction is the length direction of the fixing seat 300, the positioning hole 301 penetrates the length direction of the fixing seat 300, the cable is arranged in the positioning hole 301 along the length direction of the fixing seat 300, and the limiting hole 302 is arranged on the side wall of the positioning hole 301, that is, the opening direction of the limiting hole 302 and the length direction of the fixing seat 300 form a certain angle.

[0028] In one of the embodiments, the limiting hole 302 is arranged in the second direction perpendicular to the first direction of the fixing seat 300, and the limiting hole 302 is arranged in the middle of the positioning hole 301. When the first direction is the length direction of the fixing seat 300, the arrangement direction (the second direction) of the limiting hole 302 is the width direction of the fixing seat 300. When the positioning hole 301 is aligned with the through hole 304, the cable can be arranged in the positioning hole 301 and the through hole 304 along the length direction of the fixing seat 300. When the positioning hole 301 is misaligned with the through hole 304, the cable in the through hole 304 is bent along the width direction of the fixing seat 300, and the cable on both sides of the through hole 302 is always in the positioning hole 301. Finally, the beginning of the cable is bent into an S shape, and then the beginning of the cable is fixed in the fixing seat 300.

[0029] In one of the embodiments, the limiting hole 302 is further provided with an elastic member 305. One end of the elastic member 305 is fixed in the limiting hole 302, and the other end of the elastic member 305 is connected with the limiting block 303. The limiting block 303 moves relative to the limiting hole 302 under the action of the elastic member 305, so as to align or misalign the through hole 304 with the positioning hole 301.

[0030] Specifically, when the elastic member 305 is in the initial state, the limiting hole 302 is aligned with the positioning hole 301. When the elastic member 305 is compressed or stretched under the force, the limiting hole 302 is misaligned with the positioning hole 301. In this way, by operating the elastic member 305, the movement of the limiting block 303 relative to the limiting hole 302 can be realized, and then the alignment of the limiting hole 302 with the positioning hole 301 can be realized. The structure is simple, and the operation is convenient.

[0031] In one of the embodiments, the limiting block 303 is further connected with an operating rod 306. The operating rod 306 at least partially protrudes from the fixing seat 300. The operating rod 306 is used to drive the limiting block 303 to move relative to the limiting hole 302.

[0032] In the embodiment, the operating rod 306 is further arranged to facilitate the movement of the limiting block 303. By pulling the operating rod 306 along the arrangement direction of the limiting hole 302, the movement of the limiting block 303 can be realized. When the force on the operating rod 306 is removed, the limiting block 302 returns to the initial state under the action of the elastic member 305, that is, the through hole 304 is aligned with the positioning hole 301 again, and the beginning of the cable is facilitated to be inserted.

[0033] In one embodiment, the limiting hole 302 is further provided with a limiting rod 307, one end of the limiting rod 307 is connected with the limiting block 303 away from the end of the operating rod 306, and the other end of the limiting rod 307 is movably arranged in the mounting hole of the fixing seat 300.

[0034] In this embodiment, the movement of the limiting block 303 is realized by the cooperation of the limiting rod 307, the elastic member 305 and the operating rod 306, and when the limiting block 303 moves to the position where the through hole 304 is misaligned with the positioning hole 301, the limiting rod 307 plays a good abutting role, preventing the reverse movement of the limiting block 303, and ensuring that the starting end of the cable is fixed between the positioning hole 301 and the through hole 304.

[0035] In one embodiment, the winding structure 200 includes a rotating rod 201 and a winding reel 202, both ends of the rotating rod 201 are movably connected to the first side plate 101 and the second side plate 102 respectively, and the winding reel 202 is installed on the rotating rod 201. The rotating rod 201 is used to drive the winding reel 202 to rotate to wind and unwind the cable. In this way, different sizes of cables can be replaced by replacing different winding reels 202 on the rotating rod 201, which is convenient for actual use. In addition, the rotating rod 201 is arranged between the first side plate 101 and the second side plate 102, and the first side plate 101 and the second side plate 102 play a good supporting role to ensure the stability of the structure. The fixing seat 300 is located on the bottom plate 103 of the mounting base 100, which is convenient for fixing the starting end of the cable on the fixing seat 300, and the operation is simple and convenient.

[0038] In this embodiment, in order to prevent the cable from loosening due to unnecessary rotation caused by its own weight, a limiting structure is further arranged on the first side plate 101, that is, the first gear 203 and the second gear 204 are engaged with each other. The second gear 204 is engaged with the first gear 203, and then the rotation of the rotating rod 201 is limited, avoiding the problem of rotation due to its own weight. In subsequent normal use, the second gear 204 only needs to be disengaged from the first gear 203.

[0039] In one of the embodiments, the first side plate 101 is provided with a mounting groove 104, the first gear 203 is located in the mounting groove 104, the mounting groove 104 is fixedly provided with a support rod 105 along the axial direction of the rotating rod 201, and the second gear 204 is movably mounted on the support rod 105 and slides relative to the support rod 105.

[0040] In the embodiment, in order to facilitate the relative movement of the second gear 204 and avoid the damage of the assembly caused by the exposure of the first gear 203 and the second gear 204, the first side plate 101 is provided with a mounting groove 104, the first gear 203 and the second gear 204 are hidden in the mounting groove 104, and the support plate 105 is arranged to facilitate the smooth movement of the second gear 204.

[0041] In one of the embodiments, the second gear 204 is further fixedly connected with an adjusting rod 205, and the adjusting rod 205 at least partially protrudes from the side of the first side plate 101 away from the rotating rod 201. In the embodiment, the adjusting rod 205 is operated to facilitate the relative movement of the second gear 204.

[0043] In the embodiment, the handle and the gear transmission assembly (i.e. the driving gear 207 and the driven gear 208) are arranged to transmit power to the rotating rod 201 to drive the rotating rod 201 to rotate, and the structure is simple and the operation is convenient.
