DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1As shown, a threaded steel joint connecting sleeve comprises a structural shell 1, wherein two structural shells 1 are symmetrically distributed on the left and right, the inner sides of the two structural shells 1 are rotatably connected with a fixing mechanism 2, the inner sides of the two structural shells 1 are fixedly sleeved with rubber rings 3 at positions away from each other, the sides of the structural shells 1 close to each other are fixedly connected with a rotating mechanism 4, and the outer sides of the two structural shells 1 are provided with a plurality of evenly distributed friction grooves 5.

[0027] It should be noted that the friction groove 5 is used to enhance the friction between the outside and the structural shell 1, so as to facilitate the fixing of the structural shell 1 and prevent the structural shell 1 from moving randomly when fixing the threaded steel bar.

[0028] like Figure 2 , Figure 3 As shown, the fixing mechanism 2 includes a worm 21, the front and rear ends of which are rotatably connected to the front and rear sides of the inner side of a wall of the structural housing 1 close to the rotating mechanism 4, the inner side of the wall of the structural housing 1 close to the rotating mechanism 4 is rotatably connected to a worm wheel 22, the upper side of the worm wheel 22 is meshed and connected with the lower side of the worm 21, a lead screw 23 is fixedly connected to the axis of the side of the worm wheel 22 away from the rotating mechanism 4, and a movable plate 24 is threadedly connected to the outer wall of the lead screw 23.

[0029] It should be noted that, when the worm 21 is rotated, the worm 21 drives the worm wheel 22 to rotate, and when the worm wheel 22 rotates, it drives the lead screw 23 to rotate, and when the lead screw 23 rotates, the movable plate 24 moves laterally. There is a self-locking effect between the worm 21 and the worm wheel 22. The worm 21 can drive the lead screw 23 to rotate, but the lead screw 23 cannot drive the worm 21 to rotate in the reverse direction.

[0030] like Figure 2 , Figure 4 As shown, a plurality of annular limiting grooves 25 are provided on the inner side of the structural housing 1 near the rotating mechanism 4 , and the protrusions on the outer wall of the moving plate 24 are slidably connected to the inner side of the limiting grooves 25 .

[0031] It should be noted that the limiting groove 25 is used to limit the state of the movable plate 24 to prevent the movable plate 24 from rotating along with the screw rod 23 when the screw rod 23 rotates.

[0032] like Figure 2 , Figure 3 As shown, a plurality of annularly distributed sliders 27 are slidably connected to the inner side of the side wall of the structural shell 1, and a clamping plate 26 is fixedly connected to the side where the plurality of sliders 27 are close to each other. A plurality of annularly distributed fixed blocks 28 are fixedly connected to the edge of the side of the movable plate 24 away from the rotating mechanism 4. The slider 27 is in the shape of a right-angled trapezoid, and the inclined surface of the slider 27 faces the side close to the outer surface of the structural shell 1. The fixed block 28 is in the shape of a right-angled trapezoid, and the inclined surface of the fixed block 28 faces the side away from the outer surface of the structural shell 1, and the inclined surface of the fixed block 28 overlaps the inclined surface of the slider 27.

[0033] It should be noted that when the movable plate 24 moves, it drives the fixed block 28 to move. When the fixed block 28 moves to the side away from the rotating mechanism 4, the fixed block 28 pushes the slider 27 to cause the clamping plate 26 to move to the side close to each other, so that the clamping plate 26 clamps the threaded steel bar.

[0034] like Figure 2 , Figure 4 As shown, a partition plate 29 is fixedly sleeved in the middle of the inner wall of the structural shell 1 , and a ceramic sheet 210 is embedded in the axis of the partition plate 29 away from the rotating mechanism 4 .

[0035] It should be noted that the partition 29 is used to isolate the inner side of the structural shell 1 into two spaces to prevent the threaded steel and the screw 23 from contacting and causing damage to the screw 23. The ceramic sheet 210 has a high hardness, which reduces the wear of the threaded steel on the partition 29.

[0036] like Figure 1 , Figure 5 As shown, the rotating mechanism 4 includes a fixed shell 41, which is semi-cylindrical in shape. Two fixed shells 41 are symmetrically distributed up and down, and the two fixed shells 41 are fixedly connected together by screws. The inner side of the fixed shell 41 is rotatably connected to two rotating blocks 42 symmetrically distributed on the left and right, and one end of the rotating blocks 42 away from each other is fixedly connected to the axis of one side of the structural shell 1 close to the fixed shell 41.

[0037] It should be noted that the rotating block 42 can rotate inside the fixed shell 41 , and the two fixed shells 41 are fixed together by screws to prevent the rotating block 42 from falling off from the inside of the fixed shell 41 .

[0038] like Figure 4 As shown, four rubber pads 43 symmetrically distributed on the left and right are fixedly sleeved on the inner sides of the two fixed shells 41 , and the left and right rubber pads 43 on the same side are located on the left and right sides of the rotating block 42 .

[0039] It should be noted that the rotating block 42 is in a T-shape, and the rubber pad 43 is used to protect both sides of the rotating block 42 to reduce the noise generated by direct collision between the rotating block 42 and the fixed shell 41 when the threaded steel bars on both sides move in opposite directions.

[0040] like Figure 5 As shown, the outer sides of the two rotating blocks 42 are rotatably connected to a plurality of evenly distributed balls 44 .

[0041] It should be noted that the balls 44 are used to reduce the friction between the rotating block 42 and the fixed shell 41 , thereby extending the service life of the rotating block 42 and the fixed shell 41 .

[0042] The working principle of the utility model is as follows: first, the rotating block 42 can rotate on the inner side of the fixed shell 41, and the two fixed shells 41 are fixed together by screws to prevent the rotating block 42 from falling off from the inner side of the fixed shell 41. The rotating block 42 is in a T-shape, and the rubber pad 43 is used to protect the two sides of the rotating block 42, and reduce the noise generated by the direct collision between the rotating block 42 and the fixed shell 41 when the threaded steel bars on both sides move in the opposite direction. The ball 44 is used to reduce the friction between the rotating block 42 and the fixed shell 41, and extend the service life of the rotating block 42 and the fixed shell 41. After the threaded steel bars are fixed by the fixing mechanism 2, the threaded steel bars and the structural shell 1 are relatively stationary. When the threaded steel bars on both sides rotate relatively, the rotating block 42 will be driven to rotate by the structural shell 1, so that the threaded steel bars on both sides cannot cause torsion to the fixed shell 41, reducing the possibility of loosening between the fixed shells 41 and avoiding disconnection between the two threaded steel bars. Finally, the worm 21 is rotated, so that the worm 21 drives the worm wheel 22 to rotate, and the worm wheel 22 rotates When the screw 23 rotates, the movable plate 24 moves laterally. There is a self-locking effect between the worm 21 and the worm wheel 22. The worm 21 can drive the screw 23 to rotate, and the screw 23 cannot drive the worm 21 to rotate in the reverse direction. The limiting groove 25 is used to limit the state of the movable plate 24 to prevent the movable plate 24 from rotating with the screw 23 when the screw 23 rotates. When the movable plate 24 moves, it drives the fixed block 28 to move. When the fixed block 28 moves to the side away from the rotating mechanism 4, the fixed block 28 moves to the side away from the rotating mechanism 4. 8 Pushing the slider 27 causes the clamping plates 26 to move toward the side where they are close to each other, so that the clamping plates 26 clamp the threaded steel bars. By rotating the worm 21, all the clamping plates 26 are close to each other, so that the clamping plates 26 squeeze the threaded steel bars and fix the threaded steel joint to the inner side of the structural shell 1. The worm 21 and the worm wheel 22 are used in the form of a self-locking effect between the worm 21 and the worm wheel 22, which reduces the possibility of the clamping plates 26 loosening the threaded steel bars and prevents the threaded steel bars from falling off from the inner side of the structural shell 1.
