Description

TECHNICAL FIELD

[0001] The application relates to the technical field of power line threading, and particularly relates to a power line hidden line installation threading device for buildings. BACKGROUND

[0002] When installing a power line in a building, hidden line installation is a commonly used method. From the safety aspect, if an accident occurs to the open line, the risk of direct contact with the human body will be significantly increased, and the degree of damage is also more serious. In comparison, the hidden line installation can slow down the aging speed of the line.

[0003] The conventional process of hidden line installation is to first embed an installation pipe, and then thread a steel wire through the installation pipe. After this step is completed, one end of the line is tied to the steel wire, and the steel wire is pulled back to drive the line to pass through the installation pipe. In order to facilitate the threading of the steel wire in the pipe and better bundle the line, the end of the steel wire connected to the line is generally wound into a loop.

[0004] However, there are certain problems in the application of this technology. When the installation pipe has many turning points, the swinging range of the steel wire and the line during threading will increase, and the steel wire and the line are prone to disengagement. The current connecting device has a complex structure and is inconvenient to install. SUMMARY

[0005] The application aims to solve the problem that the steel wire and the line are prone to disengagement during threading.

[0006] The technical scheme adopted by the application to solve the above problem is as follows: a power line hidden line installation threading device for buildings, comprising a mounting seat, a clamping block rotatably connected in the mounting seat, the outer wall of the clamping block and the inner wall of the mounting seat are coaxially arranged, and there is a clamping gap between them, the thickness of the clamping gap is less than the diameter of the line or the steel wire, a plug-in hole and at least two threading holes for installing the line or the steel wire are formed in the side wall of the clamping block, when the clamping block is rotated to a first position, the two ends of the threading hole in the side wall of the mounting seat are provided with a wire passing hole for connecting the line or the steel wire into the threading hole, when the clamping block is rotated to a second position, the clamping block pulls the steel wire or the line inserted in the threading hole to extend into the clamping gap, the plug-in hole corresponds to a circumferential limiting hole in the side wall of the mounting seat, a circumferential limiting screw is screw-connected in the circumferential limiting hole, and the circumferential limiting screw is inserted into the plug-in hole to limit the rotation of the clamping block.

[0007] Compared with the prior art, the clamping gap between the clamping block and the mounting seat in the building power line hidden line installation threading device is smaller than the diameter of the wire or steel wire. After the steel wire and the wire pass through the threading hole respectively, the steel wire and the wire are pulled towards the clamping gap by rotating the clamping block. Since the gap is smaller than the diameter of the steel wire and the wire, the steel wire and the wire are gradually clamped in this process. This clamping action can effectively prevent the steel wire and the wire from coming off during swinging, and the structure is simple, the production cost is low, and it is convenient to install. Only need to insert the steel wire and the wire into the threading hole through the threading hole when the clamping block is in the first position, and then rotate the clamping block to realize fast clamping. The wire and the steel wire are fixed in the device, and the rotation of the clamping block is limited by inserting the circumferential limiting screw into the insertion hole. Once the clamping block clamps the steel wire and the wire in the clamping gap, the rotation of the clamping block can be prevented by the fixation of the circumferential limiting screw, thereby avoiding the loosening or disengagement of the steel wire and the wire due to the rotation of the clamping block.

[0008] Further, the mounting seat further comprises a rubber soft pad sleeved on the inner wall, and the inner wall of the rubber soft pad is used to abut against the wire or the steel wire when the clamping block is in the second position. The rubber material itself has a certain friction. This friction can further enhance the fixing effect of the steel wire and the wire. The rubber soft pad can absorb part of the vibration energy, reduce the influence of vibration on the fixed state of the steel wire and the wire, prevent the steel wire and the wire from coming off due to vibration, and avoid the direct hard contact of the mounting seat and the clamping block made of metal material with the wire or the steel wire. This can prevent the outer skin of the wire and the steel wire from being scratched or worn by the clamping force.

[0009] Further, the connection between the two ends of the threading hole and the clamping block is transitioned by a circular arc surface. When the connection is a circular arc surface transition, the contact between the steel wire and the wire and the edge of the threading hole is smoother compared with a right angle or a sharp edge. This can greatly reduce the wear on the surface of the steel wire and the wire during threading.

[0010] Further, the upper end of the clamping block is recessed downward to form two grooves, which are used to facilitate the application of circumferential force to the clamping block by fingers. The grooves provide a stable force point for fingers, making it easier for workers to rotate the clamping block more accurately and easily, complete the threading and clamping operation of the steel wire and the wire, and improve work efficiency.

[0011] Further, the side of the clamping block facing the mounting seat is axially protruded to form a rotating shaft, and the center of the mounting seat is provided with a mounting hole, and the rotating shaft is inserted into the mounting hole.

[0012] Further, the limiting screw comprises a screw cap and a rod body, the connection between the rod body and the screw cap is provided with a thread for screwing with the circumferential limiting hole, and the lower part of the rod body is a smooth surface for being inserted into the insertion hole. The upper end of the screw cap is provided with a lever groove along the radial direction. Attached Figure Description

[0025] Specifically, the process of connecting electric wire 5 and steel wire 6 is as follows:

[0026] Firstly, ensure that the threading device is in the initial state, i.e., clamping block 2 is located at the first position.

[0027] Insert one end of steel wire 6 from one of the through holes 1.2 on one side of the side wall of installation seat 1, make it pass through the corresponding cutting hole 2.1 on clamping block 2, and then pass out from the other through hole 1.2 on the other side of the side wall of installation seat 1, and extend a certain distance.
