Description

Technical Field

[0001] This utility model relates to the field of wire guide technology, specifically a wire guide for building conduit. Background Technology

[0002] During building construction, the installation of building conduits is a crucial step in ensuring the normal operation of electrical and communication systems. However, existing methods for installing building conduits have many shortcomings. Traditional methods mostly rely on manual operation, requiring operators to painstakingly insert one end of the lead wire into the conduit. Due to potential bends, obstacles, or excessive length within the conduit, the lead wire is difficult to pass smoothly, which is not only time-consuming and labor-intensive but also inefficient. Some methods use wire threading machines, but existing machines mainly use multiple pairs of rollers to clamp the lead wire and then drive the rollers to rotate, using friction to achieve the wire threading operation. However, after long-term use, both the rollers and the lead wire will wear down, leading to slippage and affecting the threading efficiency.

[0003] Therefore, we have designed a building conduit wiring guide to solve the above problems. Utility Model Content

[0020] 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.

[0021] Example 1: Please refer to Figures 1-5A building conduit wiring guide includes a housing 1 with a handle 15 on its side for easy handling. A rotating shaft 2, vertically penetrating the housing 1, is rotatably mounted on the housing 1. A worm gear 3 and a circular plate 4 are mounted on the shaft 2. The circular plate 4 is located at the top of the housing 1, and two circular pieces 5 are fixed to its side. Each circular piece 5 has multiple notches arranged in a circular array along its edge. An arc-shaped plate 6 and a guide tube 7 are located at the top of the housing 1. The arc-shaped plate 6 is fixed to the housing 1 and located next to the two circular pieces 5. The guide tube 7 is horizontally penetrating and fixed to the arc-shaped plate 6. An opening is provided on the side of the guide tube 7 so that when the rotating shaft 2 rotates the circular plate 4 and the two circular pieces 5, the notches on the edges of the two circular pieces 5 can pass through the inside of the opening. A winding box 8 is mounted on the top of the housing 1 via a bracket. A winding reel is rotatably mounted inside the wire box 8, and the lead wire 9 is wound on the winding reel. An outlet is provided at the bottom of the wire box 8 and connected to the rear end of the guide tube 7. Multiple evenly spaced beads 10 are fixed on the lead wire 9. One end of the lead wire 9 passes through the guide tube 7. When it passes through the opening of the guide tube 7, it can pass between two discs 5. The evenly spaced beads 10 can be caught at the notches on the edges of the two discs 5 when passing through the opening. When the discs 5 rotate, they can cooperate with the evenly spaced beads 10 through the notches arranged in a ring array, driving the lead wire 9 to pass through the guide tube 7, thereby realizing the output and pull-back functions of the lead wire 9. A wiping structure is provided at the front end of the guide tube 7. This wiping structure includes a cylinder 11, a sponge 12, an externally threaded tube 18, and an inner... A threaded tube 19 and an externally threaded tube 18 are fixedly connected to the front end of the guide tube 7, while an internally threaded tube 19 is fixedly connected to the rear end of the cylinder 11. The cylinder 11 is connected to the front end of the guide tube 7 through the mating of the internally threaded tube 19 and the externally threaded tube 18. A sponge 12 is fixed inside the cylinder 11 with glue, and a through hole is provided in the middle for the lead wire 9 and the ball 10 to pass through. The sponge 12 is in close contact with the lead wire 9 and the ball 10. When the lead wire 9 is pulled back, the sponge 12 can clean the large particles of sand, dust, and other impurities attached to the lead wire 9 and the ball 10, preventing these large particles of impurities from getting stuck between the notch of the disc 5 and the ball 10 and affecting the rotation of the disc 5. If it is necessary to clean or replace the sponge 12, the two threaded tubes can be separated by rotating the cylinder 11, thereby removing the cylinder 11 from the guide tube. The front end of tube 7 is detached to facilitate cleaning or replacement of sponge 12 by the operator. A drive structure is installed on the housing 1, comprising a worm gear 13 and a threading machine body 14. The worm gear 13 is rotatably mounted inside the housing 1 and engages with a worm wheel 3 on the rotating shaft 2. The housing 1 is mounted on the threading machine body 14. The output shaft of the threading machine body 14 is connected to the worm gear 13. A control button on the threading machine body 14 controls the worm gear 13 to rotate forward or backward. Through the engagement of the worm wheel 3 and the worm gear 13, the rotating shaft 2 is controlled to drive the circular plate 4 and the circular disc 5 to rotate forward or backward, thereby achieving the output or pullback of the lead wire 9. A coil 17 is installed at one end of the lead wire 9 that extends from the front end of the guide tube 7. The end of the cable can be tied to the coil 17 to facilitate cable pulling when the lead wire 9 is pulled back.This allows for the threading of building conduits. To prevent dust from falling onto the circular plate 5 and affecting the transmission, a protective shell 16 is installed on the outside of the circular plate 4 and the circular plate 5. The protective shell 16 is fixed to the arc-shaped plate 6 with screws.

[0022] Operating Procedure: When using this building conduit threading and guiding device, the operator holds the handle and grip 15 of the main body 14 of the threading machine with both hands, aligns the front end of the guide tube 7 with the starting point of the building conduit, and then starts the main body 14 of the threading machine. Its output shaft drives the worm gear 13 to rotate. The worm gear 13, through its cooperation with the worm wheel 3, drives the rotating shaft 2 to rotate, which in turn causes the circular plate 4 and the circular disc 5 to rotate. The rotating disc 5, through its notch, cooperates with the ball 10 on the lead wire 9, controlling the output of the lead wire 9, allowing the lead wire 9 to pass through the building conduit until the end of the lead wire 9 with the coil 17 exits from the building conduit. The cable is passed through the end of the conduit. Then, the end of the cable to be threaded is tied to the coil 17. The main body 14 of the threading machine is started, and the worm gear 13 is controlled to rotate in the opposite direction, thereby controlling the lead wire 9 to pull back, so that the cable enters from the end of the conduit and exits from the beginning of the conduit. During this process, when the lead wire 9 is retracted, it will pass through the cylinder 11 at the front end of the guide tube 7. The sponge 12 inside the cylinder 11 will wipe away the large particles of impurities attached to the lead wire 9, so as to prevent impurities from getting stuck between the notch of the disc 5 and the bead 10. After the threading is completed, the end of the cable can be untied from the coil 17.
