Description

Technical Field

[0001] This utility model relates to the field of wiring devices, and in particular to an electrical wiring device. Background Technology

[0002] When installing electrical wiring, it is necessary to thread the wires into the pre-buried conduits, and electrical wiring devices are required for this process.

[0003] A search revealed that patent document CN219498762U discloses an electrical conduit threading device, comprising a negative pressure generator, a negative pressure main pipe, a conduit negative pressure adsorption pipe, and an adsorption rope. The negative pressure main pipe is a unidirectional negative pressure power pipe, with one end fixedly connected to the negative pressure generator and powered by it, and the other end fixedly fitted with the conduit negative pressure adsorption pipe. One end of the conduit negative pressure adsorption pipe has a connector port, and the other end has a conduit plug. The conduit negative pressure adsorption pipe is sealed and connected to the negative pressure main pipe through the connector port. The adsorption rope is a flexible rope that runs along the conduit. The advantages are that using a lightweight, flexible traction rope in conjunction with negative pressure adsorption for threading significantly reduces construction difficulty. The equipment is simple to manufacture and easy to operate, not only improving threading efficiency and shortening the construction cycle, but also saving labor, reducing the use and waste of steel wire rope, and thus lowering construction costs.

[0004] The aforementioned patent only uses negative pressure suction to thread the wires, lacking a mechanism for pulling the cables. When constructing long pipelines, it is difficult to thread the wires using only negative pressure. Therefore, we propose an electrical conduit threading device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of relying solely on negative pressure to achieve the wiring of long pipelines during construction, and to propose an electrical pipeline wiring device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An electrical conduit wiring device, comprising:

[0008] Base;

[0009] Mounting bracket, fixedly installed on the top of the base;

[0010] The first drag roller is rotatably mounted on one side of the mounting base;

[0011] A rectangular hole is provided on the mounting base;

[0012] A rectangular block is slidably installed in a rectangular hole, and a second drag roller is rotatably installed on one side of the rectangular block;

[0013] The motor is fixedly mounted on the mounting base, and the output shaft of the motor is fixedly connected to one end of the first drag roller.

[0014] An adjustment mechanism, located on the mounting base, is used to adjust the height of the rectangular block, thereby adjusting the distance between the first and second drag rollers.

[0015] Preferably, the adjustment mechanism includes a screw rotatably mounted in a rectangular hole, and the screw is threadedly connected to the rectangular block.

[0016] Preferably, the top end of the screw extends above the mounting base and is fixedly mounted with a rotating block, the top of which has a regular polygonal groove.

[0017] Preferably, the sidewall of the rectangular hole is provided with a connecting groove, and a connecting block is fixedly installed on the outer side of the rectangular block, with the outer side of the connecting block slidingly contacting the inner wall of the connecting groove.

[0018] Preferably, the top of the mounting base is provided with a reset groove, a reset plate is slidably installed in the reset groove, and a spring is fixedly installed at the bottom of the reset plate, with the bottom end of the spring fixedly connected to the bottom inner wall of the reset groove.

[0019] Preferably, a connecting plate is fixedly installed on one side of the reset plate, and a regular polygonal block is fixedly installed on the bottom of the connecting plate, with the regular polygonal block engaging with the regular polygonal slot.

[0020] Preferably, two support plates are fixedly installed on the top of the base, and a rotating block is rotatably installed on each of the two support plates. The same winding shaft is fixedly installed at one end of each of the two rotating blocks.

[0021] Preferably, a circular plate is fixedly installed at the other end of the rotating block, and a handle is fixedly installed on the circular plate.

[0022] Compared with the prior art, the advantages of this utility model are:

[0023] One end of the wire is passed between the first and second drag rollers, and then connected to the suction cord. The motor drives the first drag roller to rotate, and the first and second drag rollers drag the wire, causing it to move towards the conduit. This pulls the connecting plate upward, causing the reset plate to move upward, stretching the spring. At the same time, the connecting plate causes the regular polygonal block to move upward and disengage from the regular polygonal slot, releasing the fixing of the rotating block. Then, the rotating block is rotated, causing the screw to rotate, making the rectangular block move vertically. The rectangular block causes the second drag roller to move vertically. The distance between the first and second drag rollers is adjusted to accommodate wires of different sizes. After adjustment, the regular polygonal block is inserted into the regular polygonal slot, locking the rotating block to prevent accidental rotation.

[0024] This invention facilitates the dragging of wires, making the wire threading process easier. The distance between the first and second dragging rollers can be adjusted to accommodate wires of different sizes, making it widely applicable. Attached Figure Description
