[0019] Example 1. Please refer to Figure 1-2The present invention provides a technical solution: an electric power fitting for preventing a cable from loosening, comprising a protective sleeve 1 and a positioning component 2.

[0020] Wherein, the positioning component 2 includes: The cushion block 201 is fixedly connected to the middle part of the protective sleeve 1 , a positioning spring 202 is fixedly connected to the side of the cushion block 201 away from the protective sleeve 1 , and a clamping arc plate 203 is fixedly connected to the end of the positioning spring 202 away from the cushion block 201 , and the positioning spring 202 can support the clamping arc plate 203 .

[0022] By setting the positioning spring 202 and the clamping arc plate 203, the cable can be clamped and positioned to prevent the cable from being misplaced during subsequent clamping. At the same time, under the action of the positioning spring 202, the thickness of the cable can be adapted. At the same time, by setting the clamping arc plate 203, the clamping arc plate 203 can fit the shape of the cable. When used in conjunction with the positioning spring 202, stable positioning of the cable can be achieved.

[0024] The driving cylinder 301 is fixedly connected to the outside of the protective sleeve 1, the ball nut pair 302 is fixedly connected to the inner wall of the driving cylinder 301 and is located on the side away from the protective sleeve 1, the adsorption magnetic block 303 is fixedly connected to the side of the driving cylinder 301 away from the protective sleeve 1, the movable screw 304 is threadedly connected to the middle part of the ball nut pair 302, the movable push plate 305 is rotatably connected to the end of the movable screw 304 away from the protective sleeve 1, the movable extrusion block 306 is rotatably connected to the other end of the movable push plate 305, the extrusion frame 307 is fixedly connected to the top and bottom of the movable extrusion block 306, and the movable screw 304 can move in the ball nut pair 302.

[0025] It also includes an anti-loosening component 4, which consists of a connecting push plate 401, an extrusion frame 402, a rotating connecting plate 403, a clamping arc plate 404, a fixed clamping hemisphere 405, a rotating frame 406 and a driven connecting plate 407.

[0026] The connecting push plate 401 is rotatably connected to the middle part of the extrusion frame 307, the extrusion frame 402 is rotatably connected to the side of the connecting push plate 401 away from the extrusion frame 307, the rotating connecting plate 403 is fixedly connected to the other side of the extrusion frame 402, the clamping arc plate 404 is fixedly connected to the side of the rotating connecting plate 403 away from the connecting push plate 401, the fixed clamping hemisphere 405 is fixedly connected to the inner side of the clamping arc plate 404, the rotating frame 406 is fixedly connected to the outer side of the pad 201, the driven connecting plate 407 is rotatably connected to the middle part of the rotating frame 406, and the connecting push plate 401 can rotate and push the extrusion frame 402, the rotating connecting plate 403 and the clamping arc plate 404.

[0027] A circular groove is provided in the middle of the adsorption magnetic block 303 to accommodate the rotation of the movable screw 304. The end of the movable screw 304 away from the protective sleeve 1 passes through the drive cylinder 301, the ball nut pair 302 and the adsorption magnetic block 303 and extends to the outside of the adsorption magnetic block 303 to be rotatably connected to the movable push plate 305. A handle is provided on the outside of the movable push plate 305. The handle can push the movable push plate 305, the movable screw 304, the movable extrusion block 306 and the extrusion frame 307 to move.

[0028] A rectangular groove 1 for accommodating the rotation of the connecting push plate 401 is provided on the top and bottom of the driving cylinder 301 , and a rectangular groove 2 for accommodating the rotation of the connecting push plate 401 is provided on the outer side of the protective sleeve 1 , which can ensure the normal rotation of the connecting push plate 401 .

[0029] The driven connecting plate 407 is fixedly connected to the rotating connecting plate 403 at one side away from the rotating frame 406 . The rotating connecting plate 403 is rotatably connected to the middle part of the rotating frame 406 through the driven connecting plate 407 . The rotating connecting plate 403 can rotate in the middle part of the rotating frame 406 .

[0030] By pushing the movable push plate 305, the clamping arc plate 404 can clamp and position the outer wall of the cable. By setting the fixed clamping hemisphere 405 in the clamping arc plate 404, the friction between the clamping arc plate 404 and the cable can be increased. At the same time, the cable can be squeezed to clamp and position the cable, which can prevent the cable from loosening.

[0031] By pushing and pulling the movable push plate 305, the cable can be quickly positioned and clamped. After clamping, the movable push plate 305 can be pulled to loosen the clamping arc plate 404 and the fixed clamping hemisphere 405 from the outside of the cable, so that the cable can be quickly installed and removed, which is convenient to operate.

[0032] When the cable needs to be clamped, the cable is squeezed into the protective cover 1 through the opening on the protective cover 1. At this time, the cable contacts the clamping arc plate 203, which can squeeze the clamping arc plate 203 to compress the positioning spring 202. At the same time, the positioning spring 202 and the clamping arc plate 203 can clamp and position the outside of the cable.

[0033] By pushing the movable push plate 305, the movable push plate 305 pushes the movable lead screw 304. At this time, the movable lead screw 304 rotates in the ball nut pair 302 inside the drive cylinder 301, and at the same time, the movable lead screw 304 moves inside the drive cylinder 301, so that the movable lead screw 304 pushes the movable extrusion block 306 to move, making the movable push plate 305 contact the adsorption magnet block 303. At this time, the adsorption magnet block 303 adsorbs and fixes the movable push plate 305. When the movable extrusion block 306 and the first extrusion frame 307 move, they can squeeze the connecting push plate 401, causing the second extrusion frame 402 on the other side of the connecting push plate 401 to be stressed, and at the same time pushing the rotating connecting plate 403, so that the driven connecting plate 407 on the rotating connecting plate 403 rotates inside the rotating frame 406, enabling the clamping arc plate 404 on the rotating connecting plate 403 to contact the outer wall of the cable and clamp and squeeze the outer wall of the cable, which can prevent the cable from loosening.

[0034] When it is necessary to remove the cable, just pull the handle on the movable push plate 305 outward, which can separate the movable push plate 305 from the adsorption magnet block 303. At the same time, the movable lead screw 304 moves inside the ball nut pair 302, causing the movable lead screw 304, the movable extrusion block 306 and the first extrusion frame 307 to move simultaneously. At this time, the first extrusion frame 307 pulls the connecting push plate 401, and the connecting push plate 401 pulls the second extrusion frame 402 and the rotating connecting plate 403, enabling the rotating connecting plate 403 to be separated from the outer wall of the cable, and the cable can be quickly pulled out from the opening on the protective sleeve 1.
