[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1 and Figure 2 The utility model provides an embodiment: an assembled building embedded electrical pipeline device, including a wall 1, a groove 2 is opened inside the wall 1, a embedded pipe 3 is fixedly connected inside the groove 2, a handle 4 is arranged at the top of the embedded pipe 3, a traction rope 5 is fixedly connected to the middle of the bottom end of the handle 4, the end of the traction rope 5 passes through the embedded pipe 3 and is fixedly connected to a semi-workpiece 6, a fixed block 7 is fixedly connected to the front end of the semi-workpiece 6, the upper, lower, left and right ends of the fixed block 7 are all fixedly connected to support assemblies, a rotating assembly is arranged at the rear end of the fixed block 7, and slide grooves 18 are opened on both sides of the upper and lower ends of the front end of the fixed block 7, the two slide grooves 18 are slidably connected to the clamping plate assemblies, and the two clamping plate assemblies are meshed and connected with the outer ends of the support assemblies.

[0023] The staff member holds the handle 4 and puts the traction rope 5 from the top of the embedded tube 3 into the interior of the embedded tube 3. The four supporting components allow the device to enter smoothly and pass through the bends smoothly; the wires are clamped at the axial core of 3 by the rotating component and the two clamping plate components. When the clamping plate component drives the wires to pass through the embedded tube 3, the four supporting components enable the staff member to pull the traction rope 5 in whichever direction to ensure that the wires are located in the middle of the embedded tube 3, thereby reducing the friction between the wires and the embedded tube, preventing the wires from being damaged due to excessive friction, and increasing the service life of the wires. While expanding the scope of application, it reduces the difficulty of operation for the staff.

[0024] Reference Figure 2 and 3 The left support assembly includes a connecting block 8 and a spring 14. The right end of the connecting block 8 is rotatably connected to the left end of the fixed block 7. A movable groove 9 is provided inside the connecting block 8. A movable plate 10 is provided inside the movable groove 9. The four corners of the left end of the movable plate 10 are fixedly connected to one end of the spring 14. The other end of the spring 14 is fixedly connected to the left end of the movable groove 9. A connecting shaft 11 is fixedly connected to the middle of the left end of the movable plate 10. The left end of the connecting shaft 11 passes through the left end of the connecting block 8 and is fixedly connected to a fixing member 12. The left end of the fixing member 12 is rotatably connected to a roller 13. The outer side of the movable plate 10 is in contact with the inner wall of the connecting block 8, and the outer ends of the four rollers 13 are in contact with the inner wall of the embedded pipe 3.

[0025] When the roller 13 is squeezed, it will move toward the connecting block 8. When the connecting block 8 moves, the connecting shaft 11 drives the movable plate 10 to move inside the movable groove 9, so that the spring 14 is stretched. When the movable groove 9 moves to the outside of the embedded pipe 3, the spring 14 causes the movable plate 10, the connecting shaft 11, the fixing part 12 and the roller 13 to reset synchronously, which can be applicable to embedded pipes of different radii.

[0026] Reference Figure 4 The rotating assembly includes a knob 15, the front end of the knob 15 is fixedly connected to the rear end of the fixed block 7, the middle part of the front end of the knob 15 is fixedly connected to a rotating shaft 16, the end of the rotating shaft 16 passes through the rear end of the fixed block 7 and is fixedly connected to a gear 17, the clamp assembly includes a clamp 1 22, the clamp 1 22 is located at the front end of the fixed block 7, the rear end of the clamp 1 22 is fixedly connected to a slider 19, the rear end of the slider 19 is fixedly connected to a bending plate 20, the rear end of the bending plate 20 is fixedly connected to a rack 21, the opposite ends of the two racks 21 are meshed with the outer end of the gear 17, the two sliders 19 are located in the same side slide groove 18, the slider 19 is slidably connected to the same side slide groove 18, and the bending plate 20 is composed of two vertical plates and one horizontal plate.

[0027] Rotate the knob 15 to make the shaft 16 drive the gear 17 to rotate. Since the two racks 21 are meshed with the outer side of the gear 17, the two racks 21 move in opposite directions, and the slider 19 moves in opposite directions in the same side slide groove 18, driving the clamping plate 22 to move in the opposite direction so that the clamping plate 22 clamps the wire and cooperates with the four rollers 13 to fit the inner wall of the embedded tube 3, so that the contact part of the wire and the clamping plate 22 is always located at the axial core part of the embedded tube 3.

[0028] Working principle: the staff holds the handle 4 and puts the traction rope 5 from the top of the embedded tube 3 into the interior of the embedded tube 3, and the four rollers 13 are squeezed inward synchronously, so that the outer side of the roller 13 fits with the inside of the embedded tube 3 and rolls to drive the fixed block 7 to move as a whole. When moving to a curve, the roller 13 on one side continues to roll, and the other rollers 13 cooperate to make the fixed block 7 pass the curve quickly until it moves to the outside of the other end of the embedded tube 3 and stops. By rotating the knob 15, the gear 17 rotates, driving the two racks 21 and the clamping plate 22 to move relative to each other, so that the clamping plate 22 clamps the wire at the axial core part of the embedded tube 3. When the clamping plate 22 clamps the wire and passes through the embedded tube 3, the four rollers 13 open the contact position of the wire. No matter in which direction the staff pulls the traction rope 5, it can ensure that the wire is located in the middle of the embedded tube 3, expanding the scope of use while reducing the difficulty of operation.
