Description

Technical Field

[0001] This utility model belongs to the field of lighting conduit wiring technology, specifically relating to a lighting conduit threading device. Background Technology

[0002] During the installation of lighting fixtures, the power supply or signal transmission wiring harnesses need to be run into conduits to achieve line protection and organization.

[0003] Traditional wire pulling operations rely heavily on manual labor. When manually pushing wire harnesses, uneven force can easily cause the harnesses to jam or bend, which is especially inefficient when dealing with longer conduits. The conduits lack a stable fixing structure, making them prone to shifting during the pulling process, causing misalignment between the wire harness and the conduit port, increasing the difficulty of pulling. Different specifications of wire harnesses, such as wires of different diameters and signal cables, require different pushing structures. Traditional tools have poor versatility, requiring frequent tool changes, further reducing construction efficiency.

[0004] Therefore, we propose a device for threading lamp conduits. Summary of the Invention

[0005] The purpose of this utility model is to provide a device for threading lighting conduits, in order to solve the problems mentioned in the background art, which are that traditional threading operations rely heavily on manual operation. When manually pushing the wire harness, uneven force can easily cause the wire harness to get stuck or bend, which is especially inefficient for longer conduits. The conduit lacks a stable fixing structure, and the conduit is prone to displacement during the threading process, causing misalignment between the wire harness and the conduit port, increasing the difficulty of threading. Different specifications of wire harnesses, such as wires of different diameters and signal lines, require different pushing structures. Traditional tools have poor versatility and require frequent tool changes, further reducing construction efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a lamp conduit threading device, comprising a frame, wherein a wire harness feeding mechanism and a conduit placement mechanism are provided on the frame; The wire harness feeding mechanism includes a fixed frame fixed to the surface of the frame. A fixed frame is movably arranged inside the fixed frame. A locking rod is fixedly installed on the side of the fixed frame. A strip-shaped hole for the locking rod to pass through is opened on the side of the fixed frame opposite to the locking rod. The surface of the locking rod has a threaded part, and a locking nut is threadedly installed at the threaded part. A wire threading tube is fixedly installed on the side of the fixed frame. A bidirectional screw is rotatably installed inside the fixed frame. One end of the bidirectional screw extends out of the fixed frame and is fixedly installed with a knob. Thread seats are threaded on the outer surfaces of both threads of the bidirectional screw. A mounting seat is fixedly installed on the upper surface of the thread seat. A motor is fixedly installed on the surface of the mounting seat. A wire threading drive wheel is fixedly installed on the output shaft of the motor. A through hole is opened on the wire threading tube opposite to the wire threading drive wheel. The two wire threading drive wheels are arranged opposite each other. The conduit placement mechanism includes a lower placement seat fixed to the surface of the frame and an upper placement seat detachably mounted on the surface of the lower placement seat. A clamping screw is threaded onto the upper placement seat, and a clamping head is fixedly mounted on the bottom end of the clamping screw.

[0007] The above solution utilizes a wire harness feeding mechanism in conjunction with a wire tube placement mechanism. A motor drives the wire feeding drive wheel to rotate, with the two wheels rotating relative to each other to feed the wire. Compared to manual feeding, this improves threading efficiency and avoids the risk of wire harness jamming or bending due to inaccurate manual force control. The bidirectional screw allows for adjustment of the distance between the two wire feeding drive wheels, accommodating wire harnesses of different thicknesses. A locking rod, locking nut, and fixing frame allow for vertical sliding, enabling height adjustment of the wire tube according to its thickness, ensuring the tube remains coaxial and guaranteeing threading accuracy. Upper and lower placement seats, along with clamping screws and clamping heads, securely hold wire tubes of varying thicknesses, further ensuring threading stability. The detachable design of the upper and lower placement seats facilitates easy assembly and disassembly of the wire tubes.

[0008] In a preferred embodiment, an anti-slip pad is attached to the side of the fixing bracket opposite the strip hole, and an anti-slip washer is attached to the side of the locking nut, with the anti-slip washer and the anti-slip pad attached to each other.

[0009] Using the above solution, both the anti-slip pad and the anti-slip washer are made of rubber. When the two are attached together, the friction between the locking nut and the fixing frame can be greatly increased. When the locking nut is tightened to lock the fixing frame, it can effectively prevent the locking nut from loosening due to device vibration and ensure the stability of the fixing frame during wire feeding.

[0010] In a preferred embodiment, a plurality of guide rods are fixedly mounted on the surface of the fixed frame, and the guide rods are slidably mounted on the upper surface of the fixed frame.

[0011] Using the above scheme, the sliding cooperation between the guide rod and the fixed frame provides guidance for the movement of the fixed frame, preventing the fixed frame from shifting left or right or tilting when sliding along the strip hole. This ensures that the fixed frame drives the wire-feeding drive wheel to always move in a direction parallel to the wire-feeding cylinder, ensuring the alignment of the drive wheel with the wire-feeding cylinder through hole and improving the stability of wire feeding.

[0012] In a preferred embodiment, the inner wall of the fixed frame is fixed with a plurality of guide bars, and the surface of the threaded seat is provided with guide grooves for sliding cooperation with the guide bars.

[0013] Using the above scheme, the sliding fit between the guide bar and the guide groove can restrict the movement direction of the threaded seat. When the bidirectional screw rotates, the threaded seat will not rotate synchronously with the screw, but can only move along the axial direction of the guide bar, ensuring that the two wire-threading drive wheels always maintain a relative arrangement state, avoiding misalignment of the drive wheels due to the rotation of the threaded seat, which would prevent the wire harness from being clamped.

[0014] In a preferred embodiment, the inner wall of the lower placement seat is covered with an anti-slip rubber pad, and the outer surface of the clamping head is covered with an anti-slip rubber sleeve.

[0015] Using the above solution, the anti-slip pad is attached to the inner wall of the lower placement seat, and the anti-slip sleeve is fitted over the clamping head. Both can increase the friction with the surface of the conduit, preventing the conduit from sliding inside the placement seat during the threading process. The rubber anti-slip pad and anti-slip sleeve can prevent the metal lower placement seat and clamping head from directly contacting the conduit, preventing the surface of the conduit from being scratched and protecting the integrity of the conduit.

[0016] In a preferred embodiment, insert plates are fixedly installed at both ends of the upper placement seat. The side of the insert plate has a groove, and a card plate is movably disposed in the groove. Both ends of the lower placement seat have slots for inserting the insert plates and slots for card plates to be engaged, and the slots and slots are interconnected.

[0017] Using the above method, during installation, insert the upper placement plate into the slot of the lower placement plate until the clip on the plate is engaged in the slot, thus fixing the upper placement plate. During disassembly, press the clip to disengage it from the slot, and then remove the upper placement plate upwards. This facilitates the quick insertion and removal of conduits, improving operational convenience.

[0018] In a preferred embodiment, the insert plate has several limiting rods and several springs fixed inside. A limiting plate is slidably installed on the outer surface of the limiting rods. The limiting plate is fixedly connected to the spring and fixed to the side of the plate.

[0019] Using the above solution, the limiting rod provides a sliding guide for the limiting plate, ensuring that the card plate can only move in a direction perpendicular to the insert plate. When the spring is in its natural state, it will push the card plate outward through the groove of the insert plate via the limiting plate, so that the card plate can automatically lock into the slot of the lower placement seat, ensuring a stable connection between the upper and lower placement seats. When disassembly is required, pressing the card plate will compress the spring, causing the card plate to retract into the groove. At this time, the insert plate can be easily pulled out, achieving quick disassembly and assembly without tools.

[0020] Compared with the prior art, the beneficial effects of this utility model are: This lamp conduit threading device uses a wire feeding mechanism in conjunction with a conduit placement mechanism. A motor drives the threading drive wheel to rotate, and the relative rotation of the two threading drive wheels on both sides achieves wire feeding. Compared with manual wire feeding, it can improve threading efficiency and avoid wire jamming and bending caused by the difficulty in accurately controlling the force of manual operation. At the same time, the rotation of the bidirectional screw can adjust the distance between the two threading drive wheels to adapt to the wire feeding effect of different specifications and thicknesses. The lighting conduit threading device uses a locking rod in conjunction with a locking nut and a fixing frame. The fixing frame can slide up and down, allowing the position and height of the threading spool to be adjusted according to the thickness of the conduit, ensuring that the threading spool is always coaxial with the conduit and thus ensuring good threading accuracy. This lighting conduit threading device uses an upper and lower mounting base with clamping screws and clamping heads to clamp and fix conduits of different thicknesses, further ensuring good threading stability. The upper and lower mounting bases are detachable, making it convenient to install and remove the conduits. Attached Figure Description

[0023] Please see Figure 1-7This utility model provides a lamp conduit threading device, including a frame 1, on which a wire harness feeding mechanism 2 and a conduit placement mechanism 3 are provided; The wire harness feeding mechanism 2 includes a fixed frame 4 fixed to the surface of the frame 1. A fixed frame 5 is movably arranged inside the fixed frame 4. Several guide rods 20 are fixedly installed on the surface of the fixed frame 5. The guide rods 20 are slidably installed on the upper surface of the fixed frame 4. The sliding cooperation between the guide rods 20 and the fixed frame 4 provides guidance for the movement of the fixed frame 5, preventing the fixed frame 5 from shifting left or right or tilting when sliding along the strip hole. This ensures that the fixed frame 5 drives the wire threading drive wheel 13 to always move in a direction parallel to the wire threading cylinder 8, ensuring the alignment of the drive wheel with the through hole of the wire threading cylinder 8 and improving the stability of wire feeding. A locking rod 6 is fixedly installed on the side of the fixed frame 5. A strip hole for the locking rod 6 to pass through is opened on the side of the fixed bracket 4 opposite to the locking rod 6. The surface of the locking rod 6 has a threaded part, and a locking nut 7 is threadedly installed at the threaded part. An anti-slip pad 18 is pasted on the side of the fixed bracket 4 opposite to the strip hole. An anti-slip washer 19 is pasted on the side of the locking nut 7. The anti-slip washer 19 and the anti-slip pad 18 are pasted together. Both the anti-slip pad 18 and the anti-slip washer 19 are made of rubber. After they are pasted together, the friction between the locking nut 7 and the fixed bracket 4 can be greatly increased. When the locking nut 7 is tightened to lock the position of the fixed frame 5, it can effectively prevent the locking nut 7 from loosening due to device vibration and ensure the stability of the fixed frame 5 during the wire feeding process. A threading tube 8 is fixedly installed on the side of the fixing frame 4. A bidirectional screw 9 is rotatably installed inside the fixing frame 4. One end of the bidirectional screw 9 extends out of the fixing frame 5 and is fixedly installed with a knob. Thread seats 10 are threaded on the outer surfaces of the two threads of the bidirectional screw 9. Several guide bars 21 are fixed on the inner wall of the fixing frame 5. The surface of the thread seat 10 is provided with a guide groove for sliding cooperation with the guide bar 21. The sliding cooperation between the guide bar 21 and the guide groove can limit the movement direction of the thread seat 10. When the bidirectional screw 9 rotates, the thread seat 10 will not rotate synchronously with the screw, but can only move along the axial direction of the guide bar 21, ensuring that the two threading drive wheels 13 always maintain a relative arrangement state, and avoiding misalignment of the drive wheels due to the rotation of the thread seat 10, which would prevent the wire harness from being clamped. A mounting base 11 is fixedly installed on the upper surface of the threaded seat 10. A motor 12 is fixedly installed on the surface of the mounting base 11. A wire-threading drive wheel 13 is fixedly installed on the output shaft of the motor 12. A through hole is opened on the wire-threading tube 8 facing the wire-threading drive wheel 13. The two wire-threading drive wheels 13 are arranged opposite each other. The conduit placement mechanism 3 includes a lower placement seat 14 fixed to the surface of the frame 1 and an upper placement seat 15 detachably mounted on the surface of the lower placement seat 14. Both ends of the upper placement seat 15 are fixedly mounted with insert plates 24. The side of the insert plate 24 is provided with a groove, and a locking plate 25 is movably disposed in the groove. Both ends of the lower placement seat 14 are provided with slots for inserting the insert plate 24 and slots for locking the locking plate 25. The slots and slots are interconnected. During installation, the insert plate 24 of the upper placement seat 15 is inserted into the slot of the lower placement seat 14 until the locking plate 25 on the insert plate 24 is locked into the slot, thus fixing the upper placement seat 15. During disassembly, the locking plate 25 is pressed to disengage from the slot, and the upper placement seat 15 can be taken out upwards, which facilitates the quick insertion and removal of conduits and improves the ease of operation. The insert plate 24 has several limiting rods 27 and several springs 28 fixed inside. The outer surface of the limiting rods 27 is slidably mounted with a limiting plate 26. The limiting plate 26 is fixedly connected to the springs 28 and is fixed to the side of the clamping plate 25. The limiting rods 27 provide sliding guidance for the limiting plate 26, ensuring that the clamping plate 25 can only move in a direction perpendicular to the insert plate 24. When the springs 28 are in their natural state, they will push the clamping plate 25 outward through the limiting plate 26 to extend outward from the groove of the insert plate 24, so that the clamping plate 25 can automatically engage with the slot of the lower placement seat 14, ensuring a stable connection between the upper placement seat 15 and the lower placement seat 14. When disassembly is required, pressing the clamping plate 25 will compress the springs 28, causing the clamping plate 25 to retract into the groove. At this time, the insert plate 24 can be easily pulled out, achieving quick disassembly and assembly without tools. A clamping screw 16 is threaded onto the upper placement seat 15, and a clamping head 17 is fixedly installed at the bottom end of the clamping screw 16. An anti-slip rubber pad 22 is pasted on the inner wall of the lower placement seat 14, and an anti-slip rubber sleeve 23 is fitted on the outer surface of the clamping head 17. The anti-slip rubber pad 22 is attached to the inner wall of the lower placement seat 14, and the anti-slip rubber sleeve 23 is fitted on the outside of the clamping head 17. Both can increase the friction with the surface of the conduit, preventing the conduit from sliding in the placement seat during the threading process. The rubber anti-slip rubber pad 22 and anti-slip rubber sleeve 23 can prevent the metal lower placement seat 14 and clamping head 17 from directly contacting the conduit, preventing the surface of the conduit from being scratched and protecting the integrity of the conduit.

[0024] When using Conduit fixing: Press the clamping plate 25 so that the clamping plate 25 drives the limiting plate 26 to slide on the surface of the limiting rod 27. When the limiting plate 26 moves, it compresses the spring 28 to deform. When the clamping plate 25 is disengaged from the slot, the upper placement seat 15 is pulled upward, and then the upper placement seat 15 is disassembled. The lamp conduit to be threaded is placed into the lower placement seat 14. The upper placement seat 15 is inserted into the slot again through the insert plate 24. Similarly, press the clamping plate 25 so that the clamping plate 25 is retracted into the groove. When the insert plate 24 is fully inserted into the slot, the elastic force of the spring 28 will drive the clamping plate 25 to move and insert into the slot, completing the installation and locking of the upper placement seat 15. Then rotate the clamping screw 16. When the clamping screw 16 rotates, it will drive the clamping head 17 to move downward. The clamping head 17 achieves clamping and fixing of the conduit through the anti-slip rubber sleeve 23. Harness adaptation adjustment: Adjust the height of the threading spool 8 according to the diameter of the conduit: unscrew the locking nut 7 and remove the anti-slip washer 19. At this time, the fixing frame 5 is unlocked. Then, hold the fixing frame 5 and move it up and down. After adjusting it to the point where the threading spool 8 is coaxial with the conduit, stop moving. Then, put the anti-slip washer 19 on the locking rod 6 and screw on the locking nut 7. Use the turning of the locking nut 7 to make the anti-slip washer 19 and the anti-slip pad 18 contact each other to achieve the position compression and locking of the fixing frame 5. The distance between the two threading drive wheels 13 is adjusted according to the thickness of the wire harness to be threaded. When adjusting, the knob is turned, which drives the bidirectional screw 9 to rotate, thereby driving the two threaded seats 10 to move the mounting seats 11 on both sides relative to each other, thereby adjusting the distance between the two threading drive wheels 13. The two threading drive wheels 13 stop rotating when they can fit snugly against both sides of the wire harness. Threading: After the wire harness passes through the threading tube 8, the motor 12 is started. The motors 12 on both sides control the two threading drive wheels 13 to rotate relative to each other, so that the wire harness is accelerated and transmitted into the wire tube, thus achieving threading.
