Description

Technical Field

[0001] The utility model relates to the technical field of wire threading devices for conveying devices, in particular to a wire threading device for building electrical construction. Background Art

[0002] In building electrical construction, various wire diameters are used, and the diameter size is selected according to specific project requirements and electrical loads. Generally, in building electrical construction, wire conduits need to be laid, and insulating wires are inserted into the conduits for laying, which is called wire threading in the conduit. This wiring method is relatively safe and reliable.

[0003] During the wire threading process, if the wire conduit is too long or has too many bends, making wire threading difficult, a traction rope with high strength and good flexibility (such as a nylon rope) is first passed through the wire conduit, and then the cable is connected to the traction rope. By pulling the traction rope, the cable is driven through the wire conduit. However, most traditional traction ropes are connected to the cable by bending and winding, which is relatively troublesome, time-consuming and laborious. Therefore, a wire threading device with convenient connection is needed. Summary of the Utility Model

[0004] The utility model discloses a wire threading device for building electrical construction, aiming to solve the technical problem that most traction ropes are connected to the cable by bending and winding, which is relatively troublesome, time-consuming and laborious.

[0005] In order to achieve the above object, the utility model adopts the following technical scheme:

[0006] A wire threading device for building electrical construction includes a cable, a first sleeve block and a second sleeve block, and further includes:

[0007] An auxiliary mechanism for improving the passing performance of the cable;

[0008] One side outer wall of the first sleeve block is connected with a threaded cylinder, and several equally spaced annularly distributed clamping blocks are installed on one side outer wall of the threaded cylinder. One side outer wall of the second sleeve block is connected with a wire hoop, and a threaded groove is opened inside the second sleeve block. One side outer wall of the clamping block far from the cable and one side inner wall of the second sleeve block are both arranged as inclined structures, and the second sleeve block is threadedly connected with the threaded cylinder through the threaded groove.

[0009] In this solution, the traction rope is connected through the wire hoop and does not need to be disassembled each time. The second sleeve block is aligned with the threaded cylinder, and the first sleeve block is rotated for screwing. During the screwing process, the second sleeve block is used to squeeze the clamping blocks, causing several clamping blocks to deform and the inclination angle to increase, finally achieving the effect of clamping the cable by several clamping blocks. At the same time, the second sleeve block is connected with the threaded cylinder, which is convenient for connection, fast in speed, and time-consuming and laborious.

[0010] In a preferred embodiment, the auxiliary mechanism includes a plurality of equally spaced annularly distributed square grooves formed at the edge of the outer wall on one side of the second sleeve block. Rollers are installed on the inner walls of the square grooves, and the circumferential outer wall of the second sleeve block near the wire hoop is provided with an arc-shaped structure.

[0011] To improve the passing performance of the second sleeve block and the like in the wire pipe, a plurality of rollers are added to the second sleeve block, thereby reducing the situation where the second sleeve block and the like are stuck at an uneven position in the pipeline, and improving the passing performance of the entire device in the pipeline.

[0012] As can be seen from the above, a wire threading device for building electrical construction includes a cable, a first sleeve block, and a second sleeve block, and further includes:

[0013] An auxiliary mechanism for improving the passing performance of the cable;

[0014] A threaded cylinder is connected to the outer wall on one side of the first sleeve block, and a plurality of equally spaced annularly distributed clamping blocks are installed on the outer wall on one side of the threaded cylinder. A wire hoop is connected to the outer wall on one side of the second sleeve block. A threaded groove is formed inside the second sleeve block. The outer wall on the side of the clamping block away from the cable and the inner wall on one side of the second sleeve block are both provided with inclined structures. The second sleeve block is threadedly connected to the threaded cylinder through the threaded groove. The wire threading device for building electrical construction provided by the present invention has the technical effect of convenient connection. Description of the Drawings

[0019] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative efforts belong to the scope of protection of the present application.

[0020] A wire threading device for building electrical construction disclosed by the present utility model is mainly applied to the scenario where most traditional traction ropes are connected to the cable by bending and winding, which is relatively troublesome, time-consuming and laborious.

[0021] Referring to Figure 1 and Figure 2 , a wire threading device for building electrical construction includes a cable 1, a first sleeve block 2 and a second sleeve block 3, and further includes:

[0022] An auxiliary mechanism for improving the passing performance of the cable 1;

[0023] One side outer wall of the first sleeve block 2 is fixedly connected with a threaded cylinder 5, and a plurality of equally spaced annularly distributed clamping blocks 6 are fixedly installed on one side outer wall of the threaded cylinder 5. One side outer wall of the second sleeve block 3 is fixedly connected with a wire hoop 7. A threaded groove is opened inside the second sleeve block 3, and the second sleeve block 3 is threadedly connected with the threaded cylinder 5 through the threaded groove. The outer diameter of the first sleeve block 2 is the same as the outer diameter of the second sleeve block 3, and the clamping blocks 6, the second sleeve block 3 and the threaded cylinder 5 are used in cooperation.

[0024] Wherein, one side outer wall of the clamping block 6 far from the cable 1 and one side of the inner wall of the second sleeve block 3 are both set as inclined structures, and the slope of the second sleeve block 3 is greater than that of the clamping block 6, so that the second sleeve block 3 can be used to squeeze the clamping block 6 to fix the cable 1.

[0025] Furthermore, the wire hoop 7 is connected to the traction rope and does not need to be disassembled every time.

[0026] In the specific use process, the first sleeve block 2, the threaded cylinder 5 and a plurality of clamping blocks 6 are first sleeved on the cable 1, and then the second sleeve block 3 is sleeved on. The second sleeve block 3 is aligned with the threaded cylinder 5, and then the first sleeve block 2 is rotated for screwing connection. During the screwing connection process, the second sleeve block 3 is used to squeeze the clamping block 6, so that a plurality of clamping blocks 6 are deformed. Finally, the second sleeve block 3 is connected with the threaded cylinder 5, and a plurality of clamping blocks 6 fix the cable 1, and then wire threading can be carried out.

[0027] Referring to Figure 1 and Figure 3, in a preferred embodiment, the auxiliary mechanism includes a plurality of equally spaced annularly distributed square grooves 8 formed at the edge of the outer wall on one side of the second sleeve block 3, and rollers 9 are installed on the inner walls of the square grooves 8.

[0028] Wherein, the circumferential outer wall of the second sleeve block 3 on the side close to the wire clamp 7 is arranged as an arc structure to improve the passing performance in the wire conduit.

[0029] Specifically, there are some small protrusions or depressions inside some wire conduits. When the second sleeve block 3 passes through these small protrusions and depressions, it may get stuck at the protrusions or depressions. The arc-shaped outer wall can improve the passing performance of the second sleeve block 3 in the wire conduit. By installing the rollers 9, the front end of the second sleeve block 3 can slide inside the wire conduit using the rollers 9, which can further improve its passing performance.

[0030] Working principle: During use, first put the first sleeve block 2, the threaded barrel 5 and several clamping blocks 6 on the cable 1, then put on the second sleeve block 3. Align the second sleeve block 3 with the threaded barrel 5, and then rotate the first sleeve block 2 for screwing. During the screwing process, use the second sleeve block 3 to squeeze the clamping blocks 6, causing the several clamping blocks 6 to deform. Finally, the second sleeve block 3 is connected to the threaded barrel 5, and the several clamping blocks 6 fix the cable 1. Then the threading can be carried out. When threading, the rollers 9 sliding inside the wire conduit can improve the passing performance of the device.

[0031] As described above, only the preferred specific embodiments of the present invention are provided, but the protection scope of the present invention is not limited thereto. The substitution may be the substitution of part of the structure, device, method steps, or a complete technical solution. Any equivalent substitution or change made according to the technical solution of the present invention and its inventive concept should be covered within the protection scope of the present invention.
