[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1-5As shown, this embodiment provides a convenient cable laying device for building electromechanical installation, including a bracket 2, a fixed pulley 3, and a wire 4, as well as a locking device 5 and a cable management wheel 7. The fixed pulley 3 is rotatably mounted on the upper part of the front end face of the bracket 2. A vertically arranged groove 6 is provided on the front end face of the bracket 2 below the fixed pulley 3. A slider 75 is fixedly mounted on the rear end of the cable management wheel 7, and the slider 75 is slidably mounted in the groove 6. A locking device 5 is installed on the edge of the bracket 2 on one side of the fixed pulley 3. One end of the wire 4 passes through the fixed pulley 3 and then through the locking device 5, where the locking device 5 clamps the wire 4. The other end of the wire 4 passes through the cable management wheel 7, which is provided with a tightening device for clamping the wire 4. This embodiment achieves the organization and adjustment of the wire 4 through the fixed pulley 3 and the cable management wheel 7. By setting the locking device 5 and the tightening device, both ends of the wire 4 can be clamped to prevent slippage, avoiding the problem of sagging at overhead locations, improving the laying efficiency, and facilitating subsequent processing.

[0025] The bracket 2 is fixed with bracket fixing plates 1 at both its upper and lower ends. During use, the bracket 2 is fixed in the set position by the bracket fixing plates 1. The upper and lower ends of the locking device 5 are respectively fixed with fixing ribs 50. The fixing ribs 50 are fixed to the side end face of the bracket 2 by internal hex screws 51, which facilitates disassembly and maintenance.

[0026] To elaborate on the above embodiments, such as... Figure 3 As shown, the locking device 5 includes a pressing cavity 52 and a wire channel. The wire channel communicates with the pressing cavity 52, and a pair of rollers 55 are installed inside the pressing cavity 52. ​​The wire 4 passes between the pair of rollers 55, and the pair of rollers 55 are connected to a drive mechanism for clamping the wire 4. The wire 4 passes around the fixed pulley 3 and enters from one end of the wire channel, passes through the pressing cavity 52, and exits from the other end of the wire channel. The drive mechanism drives the pair of rollers 55 to move closer together, thereby clamping the wire 4 between the rollers 55.

[0027] In one embodiment, the driving mechanism includes an adjusting disc 56 and two opposing rotating plates 54. An adjusting groove 53 is provided on the outer ring of the locking device 5 on one side of the pressing cavity 52. ​​The adjusting disc 56 is fitted into the adjusting groove 53, and the adjusting disc 56 is threadedly connected to the adjusting groove 53. The middle portion of each rotating plate 54 is rotatably mounted on the inner wall between the adjusting groove 53 and the pressing cavity 52. ​​One end of each rotating plate 54 is located inside the pressing cavity 52 and rotatably connected to a roller 55, while the other end is located inside the adjusting groove 53. The opposite sides of the two rotating plates 54 respectively contact the outer edge of the adjusting disc 56. Optimally, the contact position between the adjusting disc 56 and the rotating plates 54 is an inclined surface structure. Rotate the adjustment disc 56 to move it toward the pressing cavity 52. ​​Since the outer edge of the adjustment disc 56 contacts the opposite sides of the two rotating plates 54, the adjustment disc 56 will push the two rotating plates 54 to unfold in the adjustment groove 53 and clamp them in the pressing cavity 52, thereby bringing a pair of rollers 55 closer together to clamp the wire 4.

[0028] In an optimized embodiment, the locking device 5 is further provided with an auxiliary clamping mechanism to clamp the end of the wire 4 within the locking device 5, facilitating the insertion and installation of the wire 4 and adjusting its tightness to prevent slippage. Further, the auxiliary clamping mechanism includes a screw 57 and a bending spring 58. The screw 57 is threaded onto the lower end of the locking device 5, with its inner end located in the wire channel. A bending spring 58 is provided within the wire channel at a position corresponding to the inner end of the screw to clamp the wire 4. Figure 3 As shown, the wire channel at the end of the wire 4 is slightly wider. By rotating the screw 57, the bending spring 58 is driven upward to clamp the wire 4, providing a secondary clamping effect and effectively preventing the wire 4 from slipping. In this embodiment, the bending spring 58 is made of a spring-loaded metal material to ensure effective adjustment of the bending spring 58.

[0029] To elaborate on the above embodiments, such as... Figure 4As shown, the tightening device includes a threaded post 70, a rotating plate 72, a sliding sleeve 73, a hinge rod 74, and several pairs of clamping plates 71. The threaded post 70 is located at the axis of the thread-guiding wheel 7, and one end of the threaded post 70 is rotatably connected to the inner side of the thread-guiding wheel 7, while the other end is connected to the inner end face of the rotating plate 72. The rotating plate 72 is rotatably mounted on the outer end face of the thread-guiding wheel 7. The sliding sleeve 73 is sleeved on the threaded post 70, and the two are threadedly connected. Several pairs of clamping plates 71 are evenly arranged along the outer ring of the thread-guiding wheel 7. The outer end of each pair of clamping plates 71 is located outside the thread-guiding wheel 7, and the inner end is located inside the thread-guiding wheel 7. The annular surface of the thread-guiding wheel 7 is provided with holes for the clamping plates 71 to pass through. The inner end of each clamping plate 71 is hinged to one end of a hinge rod 74, and the other end of the hinge rod 74 is hinged to the outer end of the sliding sleeve 73. Rotate the rotating plate 72 to make the sliding sleeve 73 move slowly inward. The sliding sleeve 73 drives the hinge rod 74 to deflect, thereby causing the clamping plate 71 to retract and clamp the wire 4 between the clamping plates 71. Rotate the rotating plate 72 in the opposite direction to make the sliding sleeve 73 move slowly outward. The sliding sleeve 73 drives the hinge rod 74 to deflect, thereby causing the clamping plate 71 to release the wire 4 between the clamping plates 71.

[0030] Ideally, the diameter of the inner end face of the rotating plate 72 is larger than the diameter of the threaded column 70, which can limit the sliding of the sliding sleeve 73; the diameter of the outer end of the rotating plate 72 is larger than the diameter of the inner end of the rotating plate 72, so as to facilitate the rotation of the rotating plate 72.

[0031] Furthermore, in this embodiment, a fixing frame 8 is fixedly installed on the outer end face of the cable management wheel 7, and an adjustment mechanism for driving the fixing frame 8 to move vertically is provided on the side end face of the bracket 2. Preferably, the adjustment mechanism includes an adjustment bolt 9 and two mounting plates 10. The two mounting plates 10 are fixedly fixed to the side end faces of the bracket 2 above and below the fixing frame 8 at intervals. The middle of the adjustment bolt 9 passes through the fixing frame 8 and the passing part is provided with an external thread, which is threaded to the internal thread in the through hole of the fixing frame 8. The two ends of the adjustment bolt 9 pass through the two mounting plates 10 respectively, and the passing parts are rotatably connected to the mounting plates 10. By rotating the adjustment bolt 9, the fixing frame 8 can be driven to move up and down, thereby driving the cable management wheel 7 to move up and down along the slide groove 6, adjusting the height of the wire 4, effectively organizing the wire 4, and clamping and fixing the wire 4 through the locking device 5 and the tightening device, making it difficult to fall off and avoiding danger.

[0032] The working principle of this invention is as follows:

[0033] After the wire 4 passes around the fixed pulley 3, it passes through the inside of the locking device 5. By rotating the adjusting plate 56, the adjusting plate 56 moves and pushes the rotating plate 54 in the adjusting groove 53 to unfold. At this time, the rotating plate 54 in the pressing cavity 52 closes and drives a pair of rollers 55 to clamp the wire 4. Then, the screw 57 is tightened to squeeze the internal curved spring 58, so that it clamps the wire 4 a second time. The other end of the wire 4 passes around the outer ring of the wire guide wheel 7. By rotating the rotating plate 72, the sliding sleeve 73 inside the wire guide wheel 7 moves inward, causing the hinge rod 74 to shift and drive the clamping plate 71 to retract and clamp the wire 4 between the clamping plates 71. When the height of the wire 4 needs to be adjusted, simply rotate the adjusting bolt 9 so that the fixed bracket 8 connected to it threadedly rises and falls on the adjusting bolt 9, so that the fixed bracket 8 drives the wire guide wheel 7 to rise and fall.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. 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.
