Description

Technical Field

[0001] This utility model relates to the field of wire threading technology, specifically to a drive structure and a wire threading device for interior decoration. Background Technology

[0002] Electric cable threading machines are devices that replace manual labor and provide traction or pushing for cables when threading or pulling cables through walls.

[0003] For example, patent publication number CN210770145U discloses an electric threading machine, including a motor and a gearbox. The gearbox is equipped with traction wheels, and a traction channel for the thread to pass through is formed between the traction wheels. The gearbox is equipped with a planetary reduction mechanism and a bevel gear transmission mechanism. The output shaft of the motor is engaged with the input end of the planetary reduction mechanism. The output end of the planetary reduction mechanism transmits power to the vertically arranged output shaft through the bevel gear transmission mechanism. A driven gear is provided at the bottom of the traction wheel, and an output master gear is provided at the upper end of the output shaft. The output master gear meshes with the driven gear.

[0004] Although the above-mentioned device solves the problem of transmission efficiency, it still has the following drawbacks: the pull wheel used to drive the lead wire is composed of a rotating shaft and a rubber guide roller. After long-term use, the rubber guide rail wears out and needs to be replaced. The current replacement method is to unscrew the nuts on the rubber guide rollers with a wrench and replace them one by one. This method is cumbersome and inconvenient. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drive structure and a threader for interior decoration, making the replacement of the guide roller in the drive structure of the threader more convenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a driving structure, comprising two sets of base plates connected to the threader body, a rotating shaft connected to each base plate, and guide rollers sleeved on each rotating shaft. Each set of guide rollers is arranged opposite to each other, and a cover plate is connected to the top of each set of guide rollers. The cover plate is inserted into the top of the rotating shaft and fits against the top surface of the guide roller. A fixing plate is fixedly connected between the two cover plates at the top of each set of guide rollers. A threaded rod is threadedly connected to the fixing plate, and the threaded rod passes through the fixing plate and is threadedly connected to the housing of the threader body.

[0007] Furthermore, a plug rod is fixedly connected to the axis of the cover plate, and a slot corresponding to the plug rod is opened inside the rotating shaft.

[0008] Furthermore, the outer wall of the insertion rod is rotatably embedded with multiple sets of balls, which are rotatably connected to the inner wall of the slot.

[0009] Furthermore, an anti-slip screw is fixedly connected to the top end of the threaded rod.

[0010] Furthermore, the top surface of the anti-slip rotating block is provided with a sliding groove, and an anti-detachment component is slidably connected in the sliding groove. The anti-detachment component includes a T-shaped block and an L-shaped plate. The T-shaped block is slidably connected in the sliding groove, and the L-shaped plate is fixedly connected to the T-shaped block. One end of the L-shaped plate is inserted into a fixed plate, and an elastic protrusion is fixedly connected to one end of the fixed plate through the outer wall of the fixed plate.

[0011] Furthermore, two symmetrically arranged limiting blocks are fixedly connected to the top of the base plate, and the bottom surface of the guide roller is provided with a limiting groove corresponding to the guide roller.

[0012] A wiring harness for interior decoration includes a wiring harness body and the aforementioned drive structure.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figures 1 to 5 As shown, a driving structure includes two sets of base plates 8 connected to the threader body 1, a rotating shaft 9 connected to each base plate 8, and guide rollers 2 sleeved on each rotating shaft 9. Each set of guide rollers 2 is arranged opposite to each other, and a cover plate 3 is connected to the top of each set of guide rollers 2. The cover plate 3 is inserted into the top of the rotating shaft 9 and fits against the top surface of the guide roller 2. A fixing plate 4 is fixedly connected between the two cover plates 3 at the top of each set of guide rollers 2. A threaded rod 5 is threadedly connected to the fixing plate 4. The threaded rod 5 passes through the fixing plate 4 and is threadedly connected to the housing of the threader body 1.

[0023] like Figure 1 As shown, the drive structure and thread threader for interior decoration in this utility model are similar in structure to existing electric thread threaders, such as the electric thread threader disclosed in patent publication number CN210770145U. The main improvement of this utility model is that it makes the replacement of the guide roller in the drive structure of the thread threader more convenient. Figures 1 to 5 As shown, in the present invention, the drive structure and the cable threader for interior decoration are used such that the cable can be led out from the cable reel frame (shown in the figure) on the cable threader body 1 by two sets of guide rollers 2. When the guide rollers 2 are worn, they need to be replaced. When replacing them, simply rotate the threaded rod 5 to loosen the threaded rod 5 from the housing of the cable threader body 1. Then, lift the fixing plate 4 to move the cover plate 3 upward, so that the cover plate 3 is separated from the guide rollers 2 and the rotating shaft 9. With this setting, multiple guide rollers 2 in a set can be replaced at once. The axial position of the bottom surface of the cover plate 3 is inserted into the rotating shaft 9, which can ensure the stability of the guide rollers 2 when rotating.

[0024] like Figure 2 , Figure 3 and Figure 5 As shown, the cover plate 3 is fixedly connected to the shaft of the insert rod 12, and the rotating shaft 9 has a slot 15 corresponding to the insert rod 12.

[0025] Specifically, when the cover plate 3 is connected to the guide roller 2, the insertion rod 12 at the bottom of the cover plate 3 is inserted into the slot 15 inside the rotating shaft 9. When the guide roller 2 rotates, the rotating shaft 9 is driven to rotate by the motor inside the threader body 1 (not shown in the diagram). In the prior art, when the rotating shaft 9 rotates, it drives the base plate 8 to rotate. When the base plate 8 rotates, it drives the guide roller 2 to rotate. The cover plate 3 is restricted from rotating by the fixing plate 4. In this way, the stability of the fixing plate 4 is ensured, and the rotation of the guide roller 2 is not affected.

[0026] The stability of the cover plate 3 within the guide roller 2 and the rotating shaft 9 can be improved by inserting rod 12.

[0027] like Figure 3 As shown, multiple sets of balls 13 are rotatably embedded in the outer wall of the insertion rod 12, and the balls 13 are rotatably connected to the inner wall of the slot 15.

[0028] Specifically, when the shaft 9 rotates, the insertion rod 12 remains stationary. However, in order to make the shaft 9 rotate more smoothly, the ball bearing 13 can improve the smoothness of the rotation of the slot 15 and the insertion rod 12 within the shaft 9.

[0029] like Figure 2 , Figure 3 and Figure 4 As shown, an anti-slip rotating block 10 is fixedly connected to the top of the threaded rod 5. The anti-slip rotating block 10 makes the rotation of the threaded rod 5 more convenient.

[0030] like Figure 1 and Figure 2 As shown, the top surface of the anti-slip rotating block 10 is provided with a sliding groove 17, and an anti-detachment component is slidably connected in the sliding groove 17. The anti-detachment component includes a T-shaped block 16 and an L-shaped plate 11. The T-shaped block 16 is slidably connected in the sliding groove 17, and the L-shaped plate 11 is fixedly connected to the T-shaped block 16. One end of the L-shaped plate 11 is inserted into the fixing plate 4, and an elastic protrusion 6 is fixedly connected to one end of the L-shaped plate 11 through the outer wall of the fixing plate 4.

[0031] Specifically, when the anti-slip rotating block 10 rotates, the L-shaped plate 11 should be lifted so that the rotation of the anti-slip rotating block 10 does not obstruct the fixed plate 4. After the anti-slip rotating block 10 is rotated into place and fixed, the L-shaped plate 11 can be inserted into the fixed plate 4. This will prevent the anti-slip rotating block 10 from rotating and loosening due to the vibration of the threader body 1 during operation, which would cause the fixed plate 4 to loosen and the guide roller 2 to loosen.

[0032] When the L-shaped plate 11 slides, it drives the T-shaped block 16 to slide within the groove 17.

[0033] After the L-shaped plate 11 is inserted into the fixed plate 4, the elastic protrusion 6 plays a limiting role. The elastic protrusion 6 is set as an elastic block.

[0034] like Figure 2 and Figure 3 As shown, two symmetrically arranged limiting blocks 7 are fixedly connected to the top of the base plate 8, and the bottom surface of the guide roller 2 is provided with a limiting groove 14 corresponding to the guide roller 2.

[0035] Specifically, when the new guide roller 2 is installed with the rotating shaft 9, it is only necessary to fit the guide roller 2 and the rotating shaft 9 together so that the limiting groove 14 at the bottom of the guide roller 2 is engaged with the limiting block 7. After engagement, when the rotating shaft 9 drives the base plate 8 to rotate, it will drive the guide roller 2 to rotate.

[0036] A wiring harness for interior decoration includes a wiring harness body 1 and the aforementioned drive structure.

[0037] In the above structure, the threader body 1 is a mature existing technology, and the working principle of the threader body 1, and how to drive the rotating shaft 9 to rotate, can be found in the electric threading machine disclosed in the patent with publication number CN210770145U.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
