Description

Technical Field

[0001] This utility model belongs to the field of wire puller technology, and specifically relates to an electrical construction wire puller. Background Technology

[0002] Electrical cable pullers are tools specifically designed for cable pulling, commonly used in the construction, electrical, and communications industries. Their main function is to help quickly and easily move cables or wires from one location to another, reducing the time and labor intensity of manual cable pulling. Cable pullers play an important role in electrical installation and maintenance, solving problems such as complex wiring routes and narrow conduits, making cable or wire pulling more convenient and efficient.

[0003] In existing electrical construction wiring devices, the coiled wire inside the device is fixed in position by a support frame, and the outer side of the coiled wire is limited by a reinforcing rod welded to the outer ring. However, there is no limiting structure on the inner side of the coiled wire. As a result, during use, the ends of the coiled wire are not properly positioned, causing the wire ends to be placed arbitrarily and resulting in confusion. To address this issue, this utility model proposes an electrical construction wiring device. Utility Model Content

[0004] The purpose of this utility model is to provide an electrical construction wiring device to solve the problem mentioned in the background art, where the wires are installed inside the wiring device and there is insufficient protection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrical construction wiring device, comprising a reinforcing bracket and a support frame disposed inside the reinforcing bracket. The support frame consists of an inner ring, multiple reinforcing rods, and an outer ring. The multiple reinforcing rods are disposed inside the outer ring, and both ends of the reinforcing rods are welded to the inner side of the outer ring. The inner ring is disposed inside the multiple reinforcing rods. The inner ring consists of a ring frame A, a ring frame B, and symmetrically arranged inner protective mechanisms. The ring frame A is disposed on the side of the ring frame B. The symmetrically arranged inner protective mechanisms are all disposed between the ring frame A and the ring frame B. The inner protective mechanism consists of a spring-loaded component, a support plate, and a first fixed seat. The spring-loaded component is disposed on the surface of the ring frame A, the first fixed seat is disposed on the surface of the ring frame B, and the support plate is disposed between the spring-loaded component and the first fixed seat.

[0006] Preferably, the rebound assembly consists of a symmetrically arranged second fixing seat, a collar, and a torsion spring. The collar is fitted onto the surface of the ring frame A. The symmetrically arranged second fixing seats are all fixed to the surface of the ring frame A, and the symmetrically arranged second fixing seats are respectively engaged with the two ends of the collar. The torsion spring is fitted onto the surface of the ring frame A and located inside the collar. The two ends of the torsion spring are respectively fixed to the two sides of the inner wall of the collar.

[0007] Preferably, the first fixing seat is fitted onto the surface of the ring frame B, and the surface of the first fixing seat is provided with a slot, and a locking block is provided on the inner side of the slot.

[0008] Preferably, one end of the support plate is fixed to the side of the locking block, and the other end of the support plate is fixed to the side of the collar.

[0009] Preferably, the bottom end of the reinforcing bracket is provided with reinforcing wheels, and the top end of the reinforcing bracket is provided with a thickened handrail.

[0010] Preferably, a shaft passes through between the plurality of reinforcing rods and the reinforcing bracket.

[0011] Preferably, a guide wheel is welded and fixed on the reinforcing bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By designing an internal protective mechanism, the problem of the original electrical wiring harness being unable to provide adequate protection for the inside of the coiled wire after it is placed inside the harness is improved. This resulted in the wire end moving arbitrarily as the harness moved, causing the wire to become tangled. By installing an internal protective mechanism inside the harness, the coiled wire is restricted, limiting the range of motion of the wire end and ensuring the normal use of the wire.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1 to 3This utility model provides a technical solution: an electrical construction wiring device, including a reinforcing bracket 1 and a support frame 2 disposed inside the reinforcing bracket 1. The support frame 2 consists of an inner ring 22, multiple reinforcing rods 21, and an outer ring 23. The multiple reinforcing rods 21 are disposed inside the outer ring 23, and both ends of the reinforcing rods 21 are welded to the inner side of the outer ring 23. The inner ring 22 is disposed inside the multiple reinforcing rods 21 and consists of a ring frame A221, a ring frame B222, and symmetrically arranged inner protective mechanisms 223. The ring frame A221 is disposed on the side of the ring frame B222, and the symmetrically arranged inner protective mechanisms 223 are all disposed between the ring frame A221 and the ring frame B222. The protective mechanism 223 consists of a spring-loaded component 2231, a support plate 2232, and a first fixed seat 2233. The inner protective mechanism 223 provides internal and external protection for the wire inside the cable puller, preventing displacement of the wire due to movement of the cable puller and ensuring proper cable pulling. The spring-loaded component 2231 is located on the surface of the coil frame A221, the first fixed seat 2233 is located on the surface of the coil frame B222, and the support plate 2232 is located between the spring-loaded component 2231 and the first fixed seat 2233. This inner protective mechanism 223 improves upon the previous method where, when the wire was placed inside the cable puller, the coiled wire lacked a protective structure on its inner side, causing... The lack of a limit on the end position of the wire leads to arbitrary movement as the wire puller moves, causing the wire to become tangled. To address this, an inner protective mechanism 223 is installed inside the wire puller to limit the movement of the coiled wire end, ensuring its proper use. The spring-loaded assembly 2231 consists of symmetrically arranged second fixing seats 2231A, collars 2231B, and torsion springs 2231C. The collars 2231B are fitted onto the surface of the coil frame A221, and the symmetrically arranged second fixing seats 2231A are all fixed to the surface of the coil frame A221. Furthermore, the symmetrically arranged second fixing seats 2231A are engaged with both ends of the collars 2231B. In the closed state, the torsion spring 2231C is sleeved on the surface of the ring frame A221 and located inside the collar 2231B. The two ends of the torsion spring 2231C are fixed to the two sides of the inner wall of the collar 2231B respectively. The first fixing seat 2233 is sleeved on the surface of the ring frame B222. The surface of the first fixing seat 2233 has a slot 2233B, and the inner side of the slot 2233B is provided with a locking block 2233A. One end of the support plate 2232 is fixed to the side of the locking block 2233A, and the other end of the support plate 2232 is fixed to the side of the collar 2231B. The bottom end of the reinforcing bracket 1 is provided with a reinforcing wheel, and the top end of the reinforcing bracket 1 is provided with a thickened handrail 4. The reinforcing wheel facilitates the movement of the threader.

[0020] In this embodiment, preferably, a shaft passes through the multiple reinforcing rods 21 and the reinforcing bracket 1, and a guide wheel 3 is welded and fixed on the reinforcing bracket 1.

[0021] The working principle and usage process of this utility model are as follows: During the use of this electrical construction wiring device, the wire is placed inside the support frame 2 of the electrical construction wiring device. The outer side of the coiled wire is limited by the welded reinforcing rod 21 and the outer ring 23, and the inner side of the coiled wire is limited by the inner protective mechanism 223, ensuring that the range of motion of the wire end is limited during use. When it is not necessary to protect the inner side of the coiled wire, by lifting one end of the support plate 2232 upward, the locking block 2233A fixed at one end of the support plate 2232 is separated from the locking groove 2233B. The collar 2231B at the other end of the inner protective mechanism 223 rotates, and at the same time, the torsion spring 2231C deforms, causing the support plate 2232 to open and the coiled wire to lose its limitation.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
