Description

Technical Field

[0001] This utility model relates to the field of conduit processing technology, specifically to a conduit processing auxiliary device. Background Technology

[0002] Metal conduit, a key component in electrical installation engineering used to protect wires and cables, is typically made of galvanized steel pipe, stainless steel pipe, or other metal materials. It features high strength, corrosion resistance, and excellent fire resistance. The conduit body is a hollow cylinder, and both ends can be machined into threaded or smooth ports according to connection requirements. It is widely used in the laying of wires and cables in buildings, industrial plants, rail transportation, and other locations, effectively preventing wires and cables from external mechanical damage, humid environments, and high temperatures, ensuring the safe and stable operation of electrical systems.

[0003] During on-site construction, conduit comes with a standardized length from the factory, but electrical installations require cutting it to fit the specific site conditions. Currently, handheld devices such as angle grinders are commonly used for cutting on-site. However, the high-speed rotating grinding wheel of an angle grinder generates intense friction with the metal conduit, easily creating numerous irregular burrs at the cut, posing a safety hazard. Furthermore, the instability of handheld operation results in poor cut smoothness, often leading to misaligned ends and conduit deformation, affecting the connection accuracy and sealing between conduits.

[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. 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.

[0023] Please see Figures 1-5A processing auxiliary device for threading conduits includes a housing 1. A side plate 2 is screwed to the inner wall of the housing 1. A first roller 3 and a second roller 4 are rotatably connected inside the side plate 2. A gear 5 is fixedly connected to the shaft end of the first roller 3, and a gear 6 is fixedly connected to the shaft end of the second roller 4. A transmission gear 7 meshes between gears 5 and 6. A bevel gear 8 is fixedly connected to the center of the end face of gear 5, and a bevel gear 9 meshes with gear 8. A handle 1 is fixedly connected to the bottom of the housing 1. 0. A motor 11 is embedded inside the handle 10. A connecting plate 12 is fixedly connected to the inner wall of the housing 1. A transmission rod 13 is rotatably connected inside the connecting plate 12. An L-shaped plate 14 is fixedly connected to the outer wall of the housing 1. An adjusting rod 15 is threadedly connected to the top of the L-shaped plate 14. A sleeve 16 is rotatably connected to the bottom end of the adjusting rod 15. A cutter bracket 17 is fixedly connected to the bottom end of the sleeve 16. A circular cutter 18 is rotatably connected to the inner side of the cutter bracket 17. A guide rod 19 is slidably connected inside the cutter bracket 17.

[0024] Specifically, a knob 20 is fixedly connected to the top of the adjusting rod 15, and a screw hole is opened at the center of the top surface of the L-shaped plate 14, with the adjusting rod 15 connected to the screw hole by an internal thread.

[0025] Specifically, the top of the cutter holder 17 has two round holes, into which guide rods 19 are inserted, and the top of the guide rods 19 is fixedly connected to the L-shaped plate 14.

[0026] The advantage is that by placing the metal conduit to be cut between the first roller 3 and the second roller 4, both rollers are tangent to the outer surface of the metal conduit. Then, by rotating the knob 20, the adjusting rod 15 is rotated. The adjusting rod 15 is fed into the screw hole at the top of the L-shaped plate 14. This allows the adjusting rod 15 to move the sleeve 16 downward, which in turn moves the cutter support 17 downward. The cutter support 17 is limited by two guide rods 19. Conversely, it rotates with the adjusting rod 15, and the cutter support 17 moves the circular cutter 18 downward to contact the outer surface of the metal conduit. This prepares the metal conduit for subsequent cutting.

[0027] Specifically, a synchronous pulley 21 is fixedly connected to the shaft end of bevel gear 29, a synchronous belt 22 is driven by the synchronous pulley 21, a synchronous pulley 23 is driven by the synchronous belt 22, and a transmission rod 13 is fixedly connected to the center of the bottom surface of the synchronous pulley 23.

[0028] Specifically, the bottom end of the transmission rod 13 is connected to the output shaft of the motor 11 via a coupling, and annular grooves are provided on the outer walls of the first roller 3 and the second roller 4. The top of the housing 1 is connected to the top cover 24 by screws.

[0029] The advantages are that after starting the motor 11, the transmission rod 13 is driven to rotate, the transmission rod 13 drives the synchronous pulley 23, the synchronous pulley 23, in conjunction with the synchronous belt 22, drives the synchronous pulley 21 to rotate, the synchronous pulley 21 drives the bevel gear 9 to rotate, the bevel gear 9 drives the bevel gear 8, the bevel gear 8 drives the gear 5 to rotate, the gear 5 drives the transmission gear 7 to rotate, and the transmission gear 7 drives the gear 6 to rotate. In this way, the first roller 3 and the second roller 4 rotate synchronously. Since the first roller 3 and the second roller 4 are in close contact with the threaded tube to be cut, when the first roller 3 and the second roller 4 rotate, they can drive the threaded tube to rotate. Since the outer surface of the threaded tube is in close contact with the circular cutter 18, it can be cut by the circular cutter 18 as the threaded tube rotates, and the flatness of the cut can be guaranteed after cutting. At the same time, the rotational cutting method of the circular cutter 18, compared with the friction cutting of the grinding wheel, can significantly reduce the irregular burrs generated at the cut of the threaded tube, and reduce safety hazards.

[0030] Specifically, a battery 25 is installed inside the handle 10, and the battery 25 is connected to the motor 11 via wires. A charging port 26 is provided at the bottom of the handle 10.

[0031] The advantages are that a control switch is installed on the outer surface of the handle 10 to start the motor 11, and the battery 25 installed inside the handle 10 can provide independent power support for the motor 11, freeing it from the constraints of an external power cord. The entire device is small in size and can be easily carried to the construction site. The charging port 26 can be conveniently connected to an external power source to charge the battery 25 when the battery 25 is low, ensuring that the battery 25 can continuously supply power to the motor 11.

[0032] In use, firstly, the metal conduit to be cut is placed between roller 3 and roller 4, so that both rollers are tangent to the outer surface of the metal conduit. Then, the knob 20 is turned, causing the adjusting rod 15 to rotate. The adjusting rod 15 feeds into the screw hole at the top of the L-shaped plate 14, causing the sleeve 16 and the cutter support 17 to move downwards, thereby causing the circular cutter 18 to move downwards and contact the outer surface of the metal conduit, completing the preparation before cutting. Then, the control switch on the outer surface of the operating handle 10 starts the motor 11. The output shaft of the motor 11 drives the transmission rod 13 to rotate through the coupling, and the transmission rod 13 drives... Synchronous pulley 23, in conjunction with synchronous belt 22, drives synchronous pulley 21 to rotate. Synchronous pulley 21 drives bevel gear 9 to rotate, bevel gear 9 drives bevel gear 8 to rotate, bevel gear 8 drives gear 5 to rotate, gear 5 drives transmission gear 7 to rotate, and transmission gear 7 drives gear 6 to rotate. This causes roller 3 and roller 4 to rotate synchronously, driving the metal conduit to rotate. As the metal conduit rotates, the circular cutter 18, which is in close contact with its outer surface, cuts it. After cutting, the motor 11 is turned off, and the knob 20 is rotated in the opposite direction to move the circular cutter 18 upward. The cut conduit can then be removed.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
