Description

Technical Field

[0001] The utility model discloses a roller device for assisting indoor threading, belonging to the technical field of auxiliary devices for threading wire boxes. Background Art

[0002] In the current electrical wiring construction, the indoor wire tube is usually pulled manually. Before the wire is pulled, the wire that has been inserted into the wire tube is fixed to the wire. One person feeds the wire at the incoming end, and another person pulls the wire at the outgoing end. Since the wire tube has many bends, is long, and has greater friction, it is easy to cause certain damage to the wire box and the wire skin at the incoming end of the wire tube when pulling the wire. The construction requires two people to cooperate to complete it, which is time-consuming and labor-intensive, resulting in problems such as slow construction progress and low work efficiency. Utility Model Content

[0003] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a roller device for assisting indoor threading, which can protect the incoming wire box and the wire skin and improve work efficiency.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a roller device for assisting indoor threading, comprising a first bracket, a second bracket, a roller and an angle steel, wherein the first bracket comprises a first support rod and a second support rod, the front ends of the first support rod and the second support rod are connected together in a V shape, the second bracket comprises a third support rod and a fourth support rod, the front ends of the third support rod and the fourth support rod are also connected together in a V shape, the first bracket and the second bracket have the same opening direction and are arranged in parallel, the two rollers are arranged closely up and down, a threading space is formed in the middle, the two rollers are connected between the first bracket and the second bracket through a roller frame, the two ends of one outer side surface of the angle steel are respectively fixed to the rear ends of the first support rod and the third support rod, and the other outer side surface of the angle steel is parallel to the second support rod and the fourth support rod;

[0005] The connection method of the first support rod and the second support rod is: a through hole is opened at the horizontal elbow at the front end of the first support rod and the front end of the second support rod, the pin shaft passes through the through hole, and the pin shaft and the through hole are clearance-fitted, and a compression spring is arranged between the second support rod and the fourth support rod.

[0006] Preferably, the roller is a U-shaped roller or a V-shaped roller with a groove in the middle.

[0007] Preferably, the angle between the first support rod and the second support rod is 20°-60°.

[0008] Preferably, the angle between the first support rod and the second support rod is 40°.

[0009] Preferably, the roller is connected to the front ends of the first bracket and the second bracket.

[0010] Preferably, the front ends of the third support rod and the fourth support rod in the second bracket are fixedly connected together, or are connected in the same manner as the first support rod and the second support rod.

[0011] Compared with the prior art, the utility model has the following beneficial effects.

[0012] 1. The utility model is installed at the wire box at the wire inlet end of the wire tube. The wires at the wire inlet end are supported on the rollers or in the threading space between two rollers, avoiding direct contact between the wires and the wire box. The rollers convert the sliding friction between the wires and the wire box into rolling friction, reducing the damage to the wire box and the wire skin.

[0013] 2. After using the utility model, there is no need for personnel to deliver wires at the incoming line end, and only one construction worker is needed at the outgoing line end to complete the wire threading work, thereby improving work efficiency.

[0014] 3. The second support rod, the fourth support rod and the angle steel in the utility model are inserted into the wire box for positioning, so that the utility model is not easy to fall, and the compression spring makes the installation more stable. BRIEF DESCRIPTION OF THE DRAWINGS
