Description

Technical Field

[0001] The utility model belongs to the technical field of building electrical equipment, and in particular relates to a wire threader for building electrical equipment. Background Art

[0002] A wire threader for building electrical equipment is a tool that is usually used to pass wires through pipes, ducts, or other narrow spaces when installing electrical wiring in a building. It is usually made of metal or plastic, has an elongated shape, and one end is usually pointed to facilitate passing through obstacles. The function of the wire threader is to enable the wire to pass smoothly through pipes or other hard-to-reach places, thereby simplifying the installation process of electrical wiring. It can save installation time, improve work efficiency, and reduce damage or breakage that may occur during installation.

[0003] Before starting to install the electrical line, determine the pipes or spaces that need to be passed through and make sure they are free of obstacles or blockages. Choose a suitable threader according to the size and shape of the space that needs to be traversed. Usually, threaders of different lengths and shapes are available. Insert the threader into the pipe or space that needs to be traversed, making sure that the end of the threader can pass through easily. Once the threader reaches the destination, connect the wires that need to be guided to the end of the threader, and use the rigidity of the threader to guide the wires through the pipe or space. When the wires successfully pass through the pipe or space, slowly pull out the threader to ensure that the wires are completely pulled into the target position. By using the threader, installers can more easily guide the wires to the required positions, thereby saving time and labor, and ensuring that the wires safely pass through various obstacles inside the building. The problem with the above technology is that the threader needs to use its own threading end to connect and combine with the electrical cable during use. After the combination is completed, the electrical cable needs to be driven by the threading end to thread and move. However, in the process of pulling the electrical cable, there are components that cannot guide the electrical cable, so it is easy to cause the electrical cable to be entangled with surrounding foreign objects during movement, thereby reducing the use effect of the threader. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides a wire threader for building electrical equipment which can overcome the above problems or at least partially solve the above problems.

[0005] The utility model is implemented as follows: a wire threader for building electrical equipment comprises a wire threader, a winding mechanism, two guide mechanisms and two positioning mechanisms, wherein the winding mechanism is located at the top of the wire threader, the two guide mechanisms are respectively located at the front side and the rear side of the inner cavity of the wire threader, and the two positioning mechanisms are respectively located at the inner cavities of the two guide mechanisms; the winding mechanism is used for winding the electrical cable and the threading end; the guide mechanism is used for assisting the movement of the electrical cable; and the positioning mechanism is used for locating the position of the guide mechanism.

[0006] In order to improve the winding effect of the electrical cable and the threading end, preferably, the winding mechanism includes a support frame, a rotating motor and a threading roller, the threading roller is located in the inner cavity of the support frame and is rotatably connected to the inner cavity of the support frame, the rotating motor is located on the front side of the support frame, the output end on the rear side of the rotating motor is fixedly installed with the front side of the threading roller by bolts, and the rear side of the bottom of the rotating motor is fixedly installed with the front side of the support frame by bolts. By setting up the winding mechanism, the rotating motor can achieve the effect of quickly winding and resetting the electrical cable and the threading end through the mutual cooperation of the support frame and the threading roller, thereby avoiding the situation where winding cannot be performed after the threading is completed.

[0007] In order to improve the moving stability of the electrical cable, preferably, the guide mechanism includes a guide wheel, a moving block, a first spring and a pull rod. The guide wheel is located at the top of the threader and is movably connected to the top of the threader through a rotating shaft.

The front side of the first spring is fixedly connected to the inner wall of the threader. The pull rod is located on the right side of the moving block and is fixedly connected to the surface of the right side of the moving block. By setting up the guide mechanism, the moving blocks on both sides can guide and move the electrical cable through the guide wheels on both sides, thereby avoiding the situation where stable movement cannot be performed during the threading of the electrical cable.

By setting the positioning mechanism, the connecting plate can quickly position the guiding mechanism through the cooperation between the two positioning rods and the guiding mechanism, thereby avoiding the situation where the guiding mechanism cannot be positioned after being adjusted to a suitable position.

[0009] In order to improve the moving stability of the guide mechanism, preferably, the front and rear sides of the inner cavity of the threader are fixedly connected with a cylindrical rod, and the surface of the cylindrical rod is in contact with the inner cavity of the moving block. By setting the cylindrical rod, the cylindrical rod can cooperate with the moving block to achieve the function of assisting the moving block to drive the guide roller to move stably, thereby avoiding shaking of the moving block during movement.

After the positioning rod moves to the inner cavity that is out of the positioning groove, the pull rod is pulled to move, and the pull rod will drive the moving block to move during the movement, and the moving block will compress the first spring and drive the guide wheel to move during the movement. After the moving block moves to a suitable position, the threading end and the electrical cable are docked with the two guide wheels. After the docking is completed, the pull rod is released, and the elastic force of the first spring rebounds, which will quickly drive the moving block to move. The guide wheel is reset, and the moving block drives the guide wheel to fit the surface of the electrical cable during the reset process. After the fitting is completed, the connecting plate is released, and the elastic force of the second spring rebounds, which will quickly drive the positioning rod to insert into the inner cavity of the positioning groove through the connecting plate. After the positioning rod is inserted into the inner cavity of the positioning groove, the position of the guide mechanism can be quickly fixed. After the fixation is completed, the electrical cable can be driven to thread by pulling the threading end. After the threading installation is completed, the end of the electrical cable is wound around the surface of the threading roller, and then the rotating motor is started.
