[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0026] The utility model provides Figure 1-4 The anti-loosening mechanical connector shown includes an upper fastening sleeve 1, which is symmetrically installed with a lower fastening sleeve 2, and a movable cavity 3 is opened inside the lower fastening sleeve 2, and also includes:

[0027] The twisting clamping assembly 4, the movable cavity 3 is rotatably connected with a rotating rod 401, and one end of the rotating rod 401 is fixedly connected with a hexagonal nut 402, the outer ring of the rotating rod 401 is provided with a thread 403, and the outer ring of the thread 403 is threadedly connected with a clamping plate 404, and the clamping plate 404 moves inside the movable groove 405, the movable groove 405 is connected with the movable cavity 3, the clamping plate 404 matches with the clamping notch 406, and the clamping notch 406 is located on both sides of the upper fastening ferrule 1, to ensure the matching installation of the upper and lower fastening ferrules;

[0028] The closing component 5, the side wall of the locking plate 404 is fixedly connected with a closing block 501, and the closing block 501 moves inside the movable groove 502 set inside the lower fastening sleeve 2, ensuring that the top of the movable groove 405 is in a closed state, preventing impurities from entering the movable cavity 3 and affecting the rotation of the rotating rod 401.

[0029] The threads 403 are symmetrically arranged at two locations on the outer circle of the rotating rod 401 , and the threads 403 at the two locations have opposite thread directions. The outer circles of the two threads 403 are both threadedly connected with a clamping plate 404 , and when the hexagonal nut 402 is rotated, the two sets of clamping plates 404 can be driven to move towards or away from each other.

[0030] One side of the locking plate 404 is in the shape of a "7", and the two locking plates 404 located on the outer circle of the rotating rod 401 are symmetrically arranged, and the upper end parts of the "7" shape of the two locking plates 404 are respectively provided with an inclined surface 4041 on one side. When the two locking plates 404 move apart, the upper and lower fastening sleeves are matched and installed. When the two locking plates 404 move apart, the inclined surface 4041 just abuts against one side of the locking groove 406. While the locking plate 404 continues to move, the inclined surface 4041 abuts against the edge of one side of the locking groove 406 and thereby synchronously drives the downward movement of the upper fastening sleeve 1, so that the upper and lower fastening sleeves are connected more tightly, ensuring that the connection between the upper and lower fastening sleeves is not loose.

[0031] The upper end of the "7"-shaped snap plate 404 is snapped with the snap slot 406, and the lateral length of the snap slot 406 is longer than the lateral length of the upper end of the "7"-shaped snap plate 404, so that the upper fastening sleeve 1 can be directly pulled out from the outside of the snap plate 404 after the snap plate 404 is moved.

[0032] The top of the movable groove 405 is open, and the lower end of the movable groove 405 is connected to the movable cavity 3, and the inner wall of the movable groove 405 is in contact with and slidably connected to the outer wall of the vertical block of the locking plate 404, ensuring that the locking plate 404 moves linearly under the limiting action of the movable groove 405.

[0033] The closing block 501 is in a horizontal "T" shape, and the outer wall of the "T"-shaped end of the closing block 501 is in contact with and slidably connected to the inner wall of the movable groove 502. The movable groove 502 is connected to the movable groove 405. In the initial state, the closing block 501 blocks the notch of the movable groove 405 to ensure that the movable groove 405 and the movable cavity 3 are in a closed state, ensuring that the use of the rotating rod 401 is not affected. The movement of the locking plate 404 immediately drives the closing block 501 to move toward the inside of the movable groove 502, and also does not affect the movement of the locking plate 404.

[0034] Working principle: When using an anti-loosening mechanical connector, first, when the upper fastening sleeve 1 and the lower fastening sleeve 2 are plugged together (that is, when the engaging notch 406 provided inside the upper fastening sleeve 1 is sleeved on the upper end of the engaging plate 404), the rotation of the rotating rod 401 fixedly connected to the hexagonal nut 402 is adjusted by twisting the hexagonal nut 402, and the two engaging plates 404 that are threadedly connected by the threads 403 at two locations symmetrical to the outer ring of the rotating rod 401 are separated and moved inside the corresponding engaging notches 406. The two engaging plates 404 move in a phase separation manner to ensure that the upper end of the "7" shape in the engaging plate 404 is engaged with the edge of the engaging slot 406. At the same time, an inclined surface 4041 is provided at the upper end of the "7" shape in the engaging plate 404. When the engaging plate 404 moves toward the edge of the engaging slot 406, the inclined surface 4041 moves and exerts a downward pressure on the body outside the engaging slot 406 in the upper fastening sleeve 1, that is, exerts a downward pressure on the entire upper fastening sleeve 1, thereby making the upper and lower fastening sleeves more tightly installed.

[0035] After the upper fastening sleeve 1 and the lower fastening sleeve 2 are installed, the closing block 501 blocks the top of the movable groove 405, thereby preventing some impurities from entering the movable cavity 3 and affecting the rotation of the rotating rod 401 and the movement of the locking plate 404, ensuring the smooth connection of the upper and lower fastening sleeves. When the upper fastening sleeve 1 and the lower fastening sleeve 2 need to be disassembled later, the hexagonal nut 402 is rotated in the reverse direction to mobilize the rotating rod 401 to rotate in the reverse direction. At this time, the two groups of locking plates 404 move towards each other, and the upper end of the locking plate 404 moves to the inside of the locking slot 406, which makes it convenient to remove the upper fastening sleeve 1 and the lower fastening sleeve 2.

[0036] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
