DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-Figure 4 This application is described in further detail.

[0022] The present application discloses a bus duct that is vibration-proof and loose-proof. Figure 1 , Figure 2 As shown, it includes a groove body 1 and a groove body 2. The groove body 1 is provided with a protrusion 3, and the groove body 2 is provided with a groove 4 at a corresponding position. The groove body 1 and the groove body 2 are provided with the same number of protrusions 3 and grooves 4 on both sides, and the protrusions 3 and grooves 4 on both sides are symmetrically arranged, so that the groove body 1 and the groove body 2 are kept evenly stressed when they are fixedly connected, thereby improving the stability of the connection between the groove body 1 and the groove body 2.

[0023] See also Figure 2 , Figure 4 The protrusion 3 is provided with a clamping plate 1 5 and a clamping plate 2 6. Both the clamping plate 1 5 and the clamping plate 2 6 are arranged in an "L" shape, and the length of the clamping plate 2 6 is greater than the length of the clamping plate 1 5. A fixing block 7 is arranged on the inner side of the groove 4. A connecting piece is arranged between the clamping plate 2 6 and the clamping plate 1 5. The connecting piece includes a connecting rod 8. One end of the connecting rod 8 is installed on the clamping plate 2 6. A guide groove 9 is arranged on the clamping plate 1 5. The connecting rod 8 and the guide groove 9 are slidingly arranged.

[0024] See also Figure 2 , Figure 4 By driving the clamping plate 2 6 to move downward, the clamping plate 2 6 moves and the clamping plate 1 5 is driven to move along through the connecting rod 8. The connecting rod 8 slides in the guide groove 9, thereby realizing the synchronous movement between the clamping plate 2 6 and the clamping plate 1 5 and changing the distance between the clamping plate 2 6 and the clamping plate 1 5.

[0025] See also Figure 2 , Figure 4 A fixed column 10 is provided at the lower end of the clamping plate 6, and a slide groove 11 is provided at the lower end of the protrusion 3. The slide groove 11 is arranged in a long strip, and the fixed column 10 and the slide groove 11 are arranged to slide. When the fixed column 10 moves downward, the fixed column 10 drives the clamping plate 6 to follow the movement. At the same time, the clamping plate 6 slides obliquely in the protrusion 3. At this time, the clamping plate 6 drives the fixed column 10 to move in the slide groove 11, and the slide groove 11 limits the position of the fixed column 10.

[0026] See also Figure 2 , Figure 4 A fixing part is arranged between the fixing column 10 and the trough body 2, and the fixing part includes a fixing screw 12. The fixing screw 12 is arranged at one end of the fixing column 10, and a threaded barrel 13 is arranged on the fixing screw 12. A driving rod 14 is installed on the threaded barrel 13. The driving rod 14 is controlled to rotate by the staff, and the driving rod 14 drives the threaded barrel 13 to rotate on the fixing screw 12. At the same time, the threaded barrel 13 drives the fixing screw 12 to move, thereby changing the height position of the fixing screw 12.

[0027] See also Figure 2 , Figure 3 , Figure 4 An adjusting piece is arranged between the fixed column 10 and the fixed screw 12, and the adjusting piece includes an adjusting screw 15, and the adjusting screw 15 is rotatably installed on the inner side of the fixed screw 12. A gear ring 16 is installed on the lower end of the fixed column 10, and the fixed screw 12 is threadedly connected with the gear ring 16. A gear groove 17 is arranged on the inner side of the fixed screw 12, and the gear ring 16 and the gear groove 17 are slidably arranged. When the adjusting screw 15 is driven to rotate by the staff, the adjusting screw 15 drives the gear ring 16 to move, and the gear ring 16 drives the fixed column 10 to follow and move, thereby changing the overall height between the fixed screw 12 and the clamping plate 6.

[0028] The implementation principle of a bus duct that prevents vibration and loosening in the embodiment of the present application is as follows: when fixing, first place the trough body 1 and the trough body 2 relative to each other, and insert the protrusion 3 into the corresponding groove 4, so as to achieve the positioning effect. At this time, the fixed block 7 is between the clamping plate 2 6 and the clamping plate 1 5, and then the staff controls the driving rod 14 to rotate, and the driving rod 14 drives the threaded barrel 13 to rotate accordingly. The threaded barrel 13 rotates on the fixing screw 12, and the threaded barrel 13 squeezes the protrusion 3 while rotating, and drives the fixing screw 12 to descend. When the fixing screw 12 descends, it drives the clamping plate 2 6 to move accordingly. The clamping plate 2 6 drives the clamping plate 1 5 to move accordingly through the connecting rod 8. The clamping plate 2 6 and the clamping plate 1 5 descend and approach each other, so that the fixed block 7 in the middle is clamped and fixed, and the trough body 1 and the trough body 2 are quickly fixedly connected. The staff controls the driving rod 14 to rotate in the opposite direction, so as to release the fixation of the fixed block 7.

[0029] When a gap appears between the clamping plate 2 6 and the clamping plate 1 5 and the fixed block 7, the adjusting screw 15 is driven to rotate, the adjusting screw 15 drives the fixed column 10 to move, and the fixed column 10 drives the clamping plate 2 6 and the clamping plate 1 5 to follow the movement, thereby realizing the adjustment of the overall height between the clamping plate 2 6 and the fixed screw 12, avoiding the occurrence of gaps that affect the fixing effect.

[0030] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
