[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Specific examples are given below.

[0026] See also Figure 1-Figure 5 The utility model provides a wiring device for building electrical installation, comprising a base plate 1: a fixing box 3 is fixed to the top of the base plate 1; a top frame 2 is provided at the upper position of the base plate 1; a telescopic rod 4 is fixed to the top of the base plate 1 and at a position corresponding to the end corner of the top frame 2; the telescopic end of the telescopic rod 4 is fixedly connected to the top frame 2; fixing grooves are provided on both sides of the top frame 2; a fixing assembly is provided on the inner side of the fixing groove; the fixing assembly includes two arc-shaped clamping plates 5; a driving assembly is provided on the inner side of the top frame 2 and at a position corresponding to the arc-shaped clamping plates 5; a lifting assembly is provided on the inner side of the fixing box 3 and at a position corresponding to the top frame 2. During operation, the cables to be docked are first placed in the fixed grooves, and then the driving assembly drives the two arc-shaped clamping plates 5 to move in a direction close to each other, so that the cables are clamped and fixed by the arc-shaped clamping plates 5, and then the staff interface docks the two cables at the middle position of the top frame 2. This step is designed by the coordinated structure of the driving assembly and the arc-shaped clamping plates 5, so that the driving assembly can drive the two arc-shaped clamping plates 5 to move, so that the cables are clamped and fixed by the movement of the two arc-shaped clamping plates 5, which effectively ensures the stability of the cables when docking them, while reducing the labor intensity of the workers and improving the working efficiency of cable docking.

[0027] Further, such as Figure 2 and Figure 3 As shown, the drive assembly includes a transmission rod 6; the transmission rod 6 is arranged on the inner side of the top frame 2 and at a position corresponding to the arc-shaped clamping plate 5; the transmission rod 6 is rotatably connected to the top frame 2; the two arc-shaped clamping plates 5 are fixed with an internal threaded rod 9 on the side away from each other; the inner side of the internal threaded rod 9 away from the arc-shaped clamping plate 5 is threadedly connected with a driving screw 8; the transmission rod 6 and the driving screw 8 are connected to each other through a transmission chain 7. During operation, when the transmission rod 6 rotates, the driving screw 8 can be driven to rotate through the transmission chain 7, and when the driving screw 8 rotates, the arc-shaped clamping plate 5 can be moved through the internal threaded rod 9 threadedly connected thereto, so that the cable can be clamped and fixed by the movement of the arc-shaped clamping plate 5. This step is achieved through the coordinated structural design of the transmission chain 7, the driving screw 8 and the internal threaded rod 9, so that when the transmission rod 6 rotates, the arc-shaped clamping plate 5 can be driven to move, so that the cable can be clamped and fixed by the arc-shaped clamping plate 5.

[0028] Further, such as Figure 2 and Figure 3As shown, a driving worm wheel 12 is fixed at the middle position of the transmission rod 6; a driving worm 11 is provided on the inner side of the lower end of the top frame 2; the driving worm 11 is meshedly connected with the driving worm wheel 12; the lower end of the driving worm 11 extends to the outer side of the lower end of the top frame 2; a knob 13 is fixed to the end of the driving worm 11 located on the outer side of the top frame 2. During operation, when it is necessary to clamp the cable, the knob 13 is turned to rotate the driving worm 11. When the driving worm 11 rotates, the driving worm 11 meshed with the driving worm 11 drives the transmission rod 6 fixed to the driving worm 11 to rotate. This step is due to the structural design of the driving worm 11 and the driving worm wheel 12, so that when the knob 13 is turned, the driving worm 11 and the driving worm wheel 12 can drive the transmission rod 6 to rotate.

[0029] like Figure 2 and Figure 3 As shown, both sides of the end of the internal threaded rod 9 close to the driving screw 8 are fixed with limit blocks 10; the limit blocks 10 are slidably connected to the top frame 2. During operation, when the driving screw 8 rotates, the limit blocks 10 limit the rotation of the internal threaded rod 9, allowing the internal threaded rod 9 to move along the axial direction of the driving screw 8. When the internal threaded rod 9 moves, the limit blocks 10 are moved at the same time. In this step, the limit blocks 10 can limit the rotation of the internal threaded rod 9, thereby preventing the internal threaded rod 9 from rotating with the driving screw 8, allowing the internal threaded rod 9 to move along the axial direction of the driving screw 8 when the driving screw 8 rotates.

[0030] like Figure 4 As shown, the lifting assembly includes two lifting frames 14, which are vertically arranged at the inner sides of the fixed box 3 at both ends. The lifting frames 14 are slidably connected to the fixed box 3. The top ends of the lifting frames 14 are fixedly connected to the top frame 2. A lifting rack 15 is fixed to one side of the inner side of the lifting frames 14. A transmission assembly is provided inside the fixed box 3 at a position corresponding to the lifting rack 15. During operation, after the cables are fixed, the operator can easily connect the cables in all directions. The transmission assembly can drive the lifting frames 14 to move vertically, thereby adjusting the height of the top frame 2. This step is achieved through the coordinated structural design of the transmission assembly, the lifting rack 15, and the lifting frames 14. When the lifting frames 14 are driven by the transmission assembly and the lifting rack 15, the top frame 2 fixed to the lifting frames 14 can also be moved simultaneously, thereby adjusting the height of the top frame 2. This effectively improves the operator's convenience in connecting cables, improves the efficiency of the connection, and enhances the practicality of the device.

[0031] like Figure 4 and Figure 5As shown, the transmission assembly includes a transmission shaft 18; the transmission shaft 18 is arranged on the inner side of the fixed box 3; the transmission shaft 18 is rotatably connected to the fixed box 3; both ends of the transmission shaft 18 are fixed with lifting gears 16; the lifting gear 16 is meshed and connected with the lifting rack 15; one end of the transmission shaft 18 is fixed with an adjustment handle 19; a limit assembly is provided at one end of the transmission shaft 18 close to the adjustment handle 19 and at a position inside the fixed box 3. This step can be achieved through the structural design of the lifting gear 16 and the transmission shaft 18, so that when the transmission shaft 18 rotates, the lifting gear 16 fixed thereto is driven to rotate at the same time, so that when the lifting gear 16 rotates, the lifting rack 15 engaged with it drives the lifting frame 14 fixed to the lifting rack 15 to be raised and lowered, thereby adjusting the height of the top frame 2. After the adjustment is completed, the transmission shaft 18 is limited by the limiting assembly, so that the transmission shaft 18 cannot rotate, so that the lifting frame 14 can be limited and fixed. This step can be achieved through the structural design of the lifting gear 16 and the transmission shaft 18, so that when the transmission shaft 18 rotates, the lifting frame 14 can be driven to be raised and lowered through the lifting gear 16 and the lifting rack 15, thereby adjusting the height of the top frame 2, thereby improving the convenience of operation.

[0032] like Figure 5 As shown, the limit assembly includes a limit gear 17; the limit gear 17 is fixedly connected to the transmission shaft 18; a limit rack 20 is slidably connected to the inner side of the fixed box 3 and at a position corresponding to the limit gear 17; the limit rack 20 is meshed with the limit gear 17; a connecting rod 22 is fixed on the side of the limit rack 20 away from the limit gear 17; the connecting rod 22 is slidably connected to the fixed box 3; one end of the connecting rod 22 away from the limit rack 20 extends to the outside of the fixed box 3; a lifting handle 23 is fixed to the end of the connecting rod 22 located on the outside of the fixed box 3; a spring 21 is sleeved on the outside of the end of the connecting rod 22 close to the limit rack 20; one end of the spring 21 is fixedly connected to the limit rack 20; the other end of the spring 21 is fixedly connected to the fixed box 3. During operation, when it is necessary to cancel the limit on the transmission shaft 18, first pull the lifting handle 23 so that the lifting handle 23 drives the limit rack 20 to move through the connecting rod 22. When the limit rack 20 moves until it disengages from the limit gear 17, the limit rack 20 cancels the limit on the limit gear 17, thereby allowing the transmission shaft 18 fixed to the limit gear 17 to rotate. When the adjustment is completed, release the lifting handle 23. At this time, under the elastic action of the spring 21, the limit rack 20 is pushed to engage with the limit gear 17, thereby completing the rotation limit of the transmission shaft 18 through the limit gear 17. This step enables the transmission shaft 18 to be rotationally limited through the structural design of the limit gear 17 and the limit rack 20, thereby preventing the transmission shaft 18 from rotating due to external force, effectively improving the stability of the transmission shaft 18.

[0033] Working principle: When working, first place the cables to be docked in the fixed groove, then drive the two arc-shaped clamping plates 5 to move in the direction of approaching each other through the driving assembly, so that the cables are clamped and fixed by the arc-shaped clamping plates 5, and then the staff interface docks the two cables at the middle position of the top frame 2; when the cables need to be clamped, the knob 13 is turned so that the knob 13 drives the driving worm 11 to rotate, and when the driving worm 11 rotates, the driving worm 11 engaged with it drives the transmission rod 6 fixed to the driving worm 11 to rotate; when the transmission rod 6 rotates, it can be connected to the transmission chain 7 The driving screw 8 is driven to rotate. When the driving screw 8 rotates, the arc-shaped clamping plate 5 is driven to move by the built-in threaded rod 9 threadedly connected thereto, so that the cable can be clamped and fixed by the movement of the arc-shaped clamping plate 5; when the driving screw 8 rotates, the rotation of the built-in threaded rod 9 is limited by the limit block 10, so that the built-in threaded rod 9 can move along the axial direction of the driving screw 8, and the built-in threaded rod 9 moves, which drives the limit block 10 to move at the same time; when the cable is fixed, it is convenient for the operator to dock the cable in all directions, and the lifting frame 14 can be driven to move vertically by the transmission component, so that the cable can be clamped and fixed by the movement of the lifting frame 14 The top frame 2 is height-adjusted; when the lifting frame 14 needs to be moved, the limit on the transmission shaft 18 is first canceled by the limit assembly, and then the adjusting handle 19 is rotated to make the adjusting handle 19 drive the transmission shaft 18 to rotate. When the transmission shaft 18 rotates, the lifting gear 16 fixed thereto is driven to rotate at the same time, so that when the lifting gear 16 rotates, the lifting frame 14 fixed to the lifting rack 15 is driven to be raised and lowered through the lifting rack 15 meshing with it, thereby adjusting the height of the top frame 2. After the adjustment is completed, the transmission shaft 18 is limited by the limit assembly so that the transmission shaft 18 cannot rotate, thereby being able to adjust the height of the top frame 2. The lifting frame 14 is limited and fixed; when it is necessary to cancel the limit on the transmission shaft 18, first pull the lifting handle 23 so that the lifting handle 23 drives the limit rack 20 to move through the connecting rod 22. When the limit rack 20 moves until it disengages from the limit gear 17, the limit rack 20 cancels the limit on the limit gear 17, so that the transmission shaft 18 fixed to the limit gear 17 can rotate. When the adjustment is completed, release the lifting handle 23. At this time, under the elastic action of the spring 21, the limit rack 20 is pushed to engage with the limit gear 17, thereby completing the rotation limit of the transmission shaft 18 through the limit gear 17.
