Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically an electrical construction wiring device. Background Technology

[0002] Wiring devices in electrical construction typically refer to equipment used for threading wires, cables, optical fibers, and other cables. These devices are widely used in industries such as electrical engineering, communication network construction, and building construction.

[0003] Existing technology CN117458348A discloses a wiring device for building electrical construction, used for threading wires through conduits during building construction. It includes a base, a wire-laying assembly, a wire-cutting assembly, and a wire-leading assembly. The wire-laying assembly is located at one end of the base, and a lifting hydraulic cylinder is located at the end of the base furthest from the wire-laying assembly. The wire-cutting assembly is located in the middle of the base. The wire-laying assembly includes a mounting box, a spring spool, and a wire reel. The mounting box has multiple receiving slots, and the spring spool is inserted into the bottom of the receiving slots and rotatably connected to the mounting box. The wire reel is sleeved on the outside of the spring spool. The wire-leading assembly includes a mounting plate, a transmission part, a winding part, and a guide head. The mounting plate is fixedly mounted on the piston rod end of the lifting hydraulic cylinder. The wire end passes through the transmission part and the winding part in sequence and is then fixedly connected to the guide head. In this invention, the wire-leading assembly combined with the wire-laying assembly enables automatic wire threading, avoiding the need for workers to hold the wire continuously, thus saving manpower.

[0004] The aforementioned device has certain shortcomings in electrical wiring operations. It cannot perform wiring operations when changing wires. During wire replacement, the wire is prone to falling out, causing it to break inside the conduit, thus reducing the stability of the wiring operation. Secondly, during the installation of electrical conduits, the angle of the conduit can cause the wire to get stuck at corners, making it impossible to complete the wiring operation and increasing the difficulty of wiring. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] An electrical wiring device includes a first collar, a tension spring, and a second collar. The first collar is fixedly installed on the outer surface of one end of the tension spring, and the second collar is fixedly installed on the outer surface of the other end of the tension spring. A wire-threading cap for fixing the wire is spliced ​​to the ends of both the first and second collars. The first collar and the wire-threading cap, as well as the second collar and the wire-threading cap, are fixed together by a threaded structure. The end of the wire-threading cap is provided with a first buckle and a second buckle. The first and second buckles are symmetrically arranged, and one side of each of the first and second buckles is inclined. Three sets of inclined tapers are fixedly installed on the other side of each of the first and second buckles.

[0007] As a further technical solution of this utility model, the three sets of inclined cones are arranged side by side at an angle. The lower ends of the first buckle and the second buckle are provided with arc-shaped grooves. Because one side of the first buckle and the second buckle adopts an inclined structure, when the first buckle and the second buckle are inserted into the first collar and the second collar, the first buckle and the second buckle bend to one side under the action of the arc-shaped grooves. The first buckle and the second buckle are made of plastic, so that the first buckle and the second buckle can make appropriate deformation under the action of external force. The user inserts one end of the wire into the wire guide cap, so that one end of the wire is placed between the first buckle and the second buckle. After the wire guide cap is connected with the first collar and the second collar, the inclined cones of the first buckle and the second buckle are locked on the wire sheath, completing the fixing operation of the wire end, so that the two wires are respectively fixed at both ends of the tension spring.

[0008] As a further technical solution of this utility model, the outer surface of the threading cap is provided with a threaded ring, and the inner sides of the first and second rings are provided with threaded grooves for use with the threaded ring. The threaded ring and the threaded groove are used to fix the installation of the threading cap.

[0009] As a further technical solution of this utility model, a safety rope is provided inside the tension spring. The two ends of the safety rope and the tension spring are fixed to each other. The length of the safety rope is greater than the initial length of the tension spring. The safety rope protects the tension spring and prevents the tension spring from being over-tensioned during the threading operation.

[0010] As a further technical solution of this utility model, a washer is provided at one end of the first collar and the second collar, and a fixing sleeve is provided at the other end of the first collar and the second collar. The fixing sleeve plays a role in connecting and fixing the two ends of the tension spring.

[0011] As a further technical solution of this utility model, the outer surfaces of the first and second rings are provided with a number of sets of rollers, which are arranged in a ring. By using the rollers, the resistance of the threading device can be reduced when the threading device passes through the corner of the pipe, so that the rollers and the corner can make active contact.

[0012] The beneficial effects of this utility model are:

[0013] This utility model, by incorporating a wire-passing cap and a tension spring, allows for the quick and easy fixing of the original wire and the replacement wire to both ends of the tension spring during electrical construction wiring. The tension spring creates an elastic connection between the two wires. By pulling the original wire, the replacement wire can be pulled out of the conduit, thus quickly completing the wire replacement and wiring operation and preventing the wire from coming loose. During operation, because both the first and second clips have a beveled structure on one side, when the first and second clips are inserted into the first and second collars, the first clip... The first and second clips bend to one side under the action of the arc groove. The first and second clips are made of plastic, so that the first and second clips can make appropriate deformation under the action of external force. The user inserts one end of the wire into the wire cap, so that one end of the wire is placed between the first and second clips. After the wire cap, the first collar and the second collar are connected, the beveled cones of the first and second clips are locked on the wire sheath to complete the fixing operation of the wire end. The two wires are fixed to the two ends of the tension spring respectively. Pull one end of the original cable to pull the new cable out of the conduit.

[0014] By setting the first and second sets of rings, and in conjunction with the rollers, the electrical wiring device can improve its passability at pipe corners. The rollers reduce the resistance of the wiring device when it passes pipe corners, allowing for contact between the rollers and the corner. Furthermore, the safety rope is longer than the initial length of the tension spring, protecting the tension spring and preventing over-tensioning during wiring. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1-3 As shown, an electrical construction wiring device includes a first ring 2, a tension spring 3, and a second ring 4. The first ring 2 is fixedly installed on the outer surface of one end of the tension spring 3, and the second ring 4 is fixedly installed on the outer surface of the other end of the tension spring 3. Both ends of the first ring 2 and the second ring 4 are spliced ​​with wire-threading caps 1 for fixing wires. The first ring 2 and the wire-threading cap 1, as well as the second ring 4 and the wire-threading cap 1, are fixed together by threaded structure. The end of the wire-threading cap 1 is provided with a first buckle 6 and a second buckle 8. The first buckle 6 and the second buckle 8 are symmetrically arranged, and one side of the first buckle 6 and the second buckle 8 is inclined. Three sets of inclined tapers 7 are fixedly installed on the other side of the first buckle 6 and the second buckle 8.

[0022] The three sets of inclined cones 7 are arranged side by side at an angle. The lower ends of the first buckle 6 and the second buckle 8 are provided with arc-shaped grooves 5. Because one side of the first buckle 6 and the second buckle 8 is an inclined structure, when the first buckle 6 and the second buckle 8 are inserted into the first collar 2 and the second collar 4, the first buckle 6 and the second buckle 8 bend to one side under the action of the arc-shaped grooves 5. The first buckle 6 and the second buckle 8 are made of plastic, so that the first buckle 6 and the second buckle 8 can make appropriate deformation under the action of external force. The user inserts one end of the wire into the wire cap 1, so that one end of the wire is placed between the first buckle 6 and the second buckle 8. After the wire cap 1 is connected with the first collar 2 and the second collar 4, the inclined cones 7 of the first buckle 6 and the second buckle 8 are locked on the wire sheath, completing the fixing operation of the wire end, so that the two wires are respectively fixed to the two ends of the tension spring 3.

[0023] The outer surface of the threaded cap 1 is provided with a threaded ring 9, and the inner sides of the first ring 2 and the second ring 4 are provided with threaded grooves 10 that cooperate with the threaded ring 9. The threaded ring 9 and the threaded grooves 10 are used to fix the installation of the threaded cap 1.

[0024] The tension spring 3 is equipped with a safety rope 14 inside. The two ends of the safety rope 14 and the tension spring 3 are fixed to each other. The length of the safety rope 14 is greater than the initial length of the tension spring 3. The safety rope 14 protects the tension spring 3 and prevents the tension spring 3 from being over-tensioned during the threading operation.

[0025] One end of the first ring 2 and the second ring 4 is provided with a washer 13, and the other end of the first ring 2 and the second ring 4 is provided with a fixing sleeve 12. The fixing sleeve 12 serves to fix the two ends of the tension spring 3.

[0026] The outer surfaces of the first ring 2 and the second ring 4 are provided with several sets of rollers 11. The sets of rollers 11 are arranged in a ring. By using the arrangement of rollers 11, the resistance of the threading device can be reduced when the threading device passes through the corner of the pipe, so that the rollers 11 and the corner can make contact.

[0027] An electrical construction wiring device, by setting a wiring cap 1 and a tension spring 3, allows the wiring cap 1 to quickly fix the original wire and the wire to be replaced to the tension spring 3. The tension spring 3 forms an elastic connection structure between the two wires. By pulling the original wire, the wire to be replaced can be pulled out of the conduit, thus quickly completing the wire replacement and wiring operation and preventing the wire from falling off. During operation, because one side of the first clip 6 and the second clip 8 are both designed with a beveled structure, when the first clip 6 and the second clip 8 are inserted into the first collar 2 and the second collar 4, the first clip 6... The first and second buckles 8 bend to one side under the action of the arc groove 5. The first and second buckles 6 and 8 are made of plastic, so that the first and second buckles 6 and 8 can deform appropriately under the action of external force. The user inserts one end of the wire into the wire cap 1, so that one end of the wire is placed between the first and second buckles 6 and 8. After the wire cap 1, the first collar 2 and the second collar 4 are connected, the inclined cone 7 of the first and second buckles 6 and 8 is locked on the wire sheath to complete the fixing operation of the wire end. The two wires are fixed at both ends of the tension spring 3 respectively. Pull one end of the original cable to pull the new cable out of the conduit.

[0028] By setting the first set of rings 2 and the second set of rings 4, the electrical construction wiring device, in conjunction with the setting of roller 11, can improve the passability of the wiring device at the corner position of the conduit. The setting of roller 11 can reduce the resistance of the wiring device when passing through the corner position of the conduit, so that the roller 11 and the corner can make contact. Secondly, the length of the safety rope 14 is greater than the initial length of the tension spring 3. The safety rope 14 plays a protective role for the tension spring 3, preventing the tension spring 3 from being over-tensioned during the wiring operation.

[0029] The above description is merely an example and illustration of the structure of this utility model.
