Description

Technical Field

[0001] This utility model relates to the field of building electrical engineering technology, specifically to a wiring construction device for building electrical engineering. Background Technology

[0002] Electrical wiring harnesses are devices specifically designed for the installation of wires or cables in building electrical engineering projects. These harnesses aim to improve wiring efficiency, reduce the complexity and difficulty of manual operations, and ensure the safety and integrity of wires or cables during the wiring process.

[0003] In modern building electrical engineering, most cable pulling devices use a motor-driven turntable to extend the cable on its own. This type of cable pulling device is only suitable for use when the cable is heavy enough to remain straight in the pipe. However, when the cable is light and the pipe opening is narrow, pushing the cable with the turntable will cause the cable to pile up in the pipe, resulting in pipe blockage and making it impossible to pull the cable through. At the same time, because the cable is light, the thrust it receives as the turntable rotates is also small, which makes it difficult to push the cable through the pipe effectively.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Please see Figures 1 to 5This utility model provides a technical solution: a wiring device for building electrical engineering, comprising a gun barrel 1, one end of which is detachably connected to an air pump connector 4, and one end of the air pump connector 4 is fixedly connected to an air pump 3. A wire inlet 101 is opened at the bottom of the middle end of the gun barrel 1, and a coil wheel 7 is fixedly connected below the wire inlet 101. A rotating shaft 9 is fixedly connected inside the coil wheel 7, and a wire reel 8 is rotatably connected to the outer surface of the rotating shaft 9. A handle 2 is fixedly connected to the bottom of one end of the gun barrel 1, and an air pump switch 5 is installed on one side of the handle 2. The circuit connection between the air pump switch 5 and the air pump 3 is not shown in the diagram. A fixing block 17 is fixedly connected to one side of the coil wheel 7. Several fixing blocks 17 are distributed on one side of the coil wheel 7 and one side of the coil wheel cover 6, and the sizes of the fixing blocks 17 are adapted to each other. This wiring device for building electrical engineering, through the setting of the guide rod 10, enables the cable 11 to be smoothly led out of the nozzle under the guidance of the guide rod 10. Through the cooperation of the main wind baffle 13 and the auxiliary wind baffle 14, during use, the main wind baffle 13 and the auxiliary wind baffle 14 can be rotated through the main wind baffle connecting block 131 and the auxiliary wind baffle connecting block 141, so that pipes of different diameters can be threaded under the thrust of the gas pumped in by the air pump 3. This improves the application range of the device, while also having a simple structure, achieving the purpose of convenient and quick threading of lightweight cables 11, and threading pipes of different diameters, thus improving the practicality of the device.

[0025] First, remove the coil wheel cover 6 using the screws at the fixing block 17. Lead out a section of the cable 11 from the outer surface of the coil spool 8, and thread the cable 11 through the front of the coil wheel 7 to the inlet 101, and then through the guide rod 10. Lead it out from the muzzle end. After leading it out, install the coil wheel cover 6 onto the coil wheel 7 using the fixing block 17. Then, thread the fixing cylinder 15 through one end of the cable and fix the fixing cylinder 15 to the end of the cable using the cable tie 16. This ensures that the larger diameter end of the cone formed by the main wind deflector 13 and the secondary wind deflector 14 is close to the barrel 1, and the smaller diameter end is close to the end of the cable. After fixing, insert the cable end through the pipe opening. After insertion, ensure that the nozzle 12 fits against the pipe opening. Hold the handle 2 with one hand and the nozzle 12 with the other hand to ensure a tight connection between the barrel 1 and the pipe. After fitting, start the air pump 3.

[0026] Example 2

[0027] Please see Figures 1 to 5This utility model provides a technical solution: a wiring device for building electrical engineering, wherein a cable is movably connected to the outer surface of a coil spool 8, a coil wheel cover 6 is detachably connected to the front of a coil wheel 7, a nozzle connector 121 is detachably connected to the other end of a gun barrel 1, a nozzle 12 is fixedly connected to one side of the nozzle connector 121, one end of a cable passes through a guide rod 10, and a cable tie 16 is detachably connected to one end of the cable. A fixing cylinder 15 is fixedly connected to one side of the cable tie 16, and a main wind deflector connecting block 131 is fixedly connected to one side of the fixing cylinder 15. There are several main wind deflector connecting blocks 131, which are symmetrically and evenly distributed at the upper and lower ends of one side of the fixing cylinder 15. A main wind deflector 13 is rotatably connected to the outer surface of the main wind deflector connecting block 131. A secondary wind deflector connecting block 141 is fixedly connected to one side of the fixing cylinder 15, and there are several secondary wind deflector connecting blocks 141, which are symmetrically and evenly distributed on the fixing cylinder 15. On one side of the 5, the outer surface of the auxiliary wind deflector connecting block 141 is rotatably connected to the auxiliary wind deflector 14. The auxiliary wind deflector 14 is located inside the main wind deflector 13, and the enclosed space formed by the auxiliary wind deflector 14 and the main wind deflector 13 is a cone. The top of the cone is close to the end of the cable, and the bottom of the cone is close to the nozzle 12. This wiring construction device for building electrical engineering, through the setting of the nozzle 12, enables the wiring construction device for building electrical engineering to seal the pipe openings of pipes of different diameters, so that the main wind deflector 13 and the auxiliary wind deflector 14 can better advance along the pipe by wind traction. Through the cooperation of the fixing cylinder 15 and the cable tie 16, during use, the fixing cylinder 15 can be fixed to the outer surface of the cable 11 by the contraction of the cable tie 16, thereby ensuring that the main wind deflector 13 and the auxiliary wind deflector 14 are stably installed on the outer surface of the cable 11, thus achieving the purpose of ensuring the wiring efficiency and stability of the device.

[0028] When the air pump 3 is started, the main baffle 13 and the auxiliary baffle 14 will unfold outward under the action of thrust, so that the main baffle 13 and the auxiliary baffle 14 will contact the pipe wall to form a sealed space. At the same time, the main baffle 13 and the auxiliary baffle 14 will move along the pipe to the other end due to the thrust. When they encounter a small diameter part of the pipe or a blockage by foreign objects, the rotation center of the main baffle 13 and the auxiliary baffle 14 is at the fixed cylinder 15, so that they will retract with the main baffle connecting block 131 and the auxiliary baffle connecting block 141 as the rotation center. After passing through, they will unfold again under the action of thrust until they pass through the other end of the pipe. After passing through, you only need to remove the fixed cylinder 15 from one end of the cable 11 to complete the cable threading work.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
