Description

Technical Field

[0001] This invention relates to the field of electrical wire threading technology, specifically to an automatic electrical wire threading device for building decoration. Background Technology

[0002] Automated tools used in building electrical wiring installations assist in threading electrical wires through pre-buried conduits. These tools replace traditional manual wiring with mechanical power, solving problems such as low efficiency, high labor intensity, and difficulty in working at conduit bends. Most mainstream equipment uses either a "wire traction" or "motor-driven push" principle. For example, some models use a special steel wire rope to first pass through the conduit, bind the wire, and then a motor pulls the wire back to complete the threading. Other models use a micro-motor to drive components in reciprocating motion, enabling continuous wire threading and unloading. Some also include guide heads to reduce friction between the wire and the conduit wall.

[0003] In the prior art, patent document CN219106922U discloses a wire threading device, relating to the technical field of wire threading equipment. The technical solution includes a base plate, a support, a winding shaft, a pair of traction rollers and a pair of guide rollers, a power device for driving the traction rollers to rotate, and a straightening device. A gap is provided between the pair of traction rollers, the width of which is less than or equal to the wire diameter. The straightening device includes an upper support and a lower support. Multiple upper pressure rollers are rotatably connected to the side of the upper support facing the lower support, and multiple lower pressure rollers corresponding to the upper pressure rollers are rotatably connected to the side of the lower support facing the upper support. The upper or lower support is also equipped with a telescopic device for driving the upper and lower pressure rollers to move towards each other. This invention utilizes the friction between the traction rollers and the wire to pull the wire from the winding drum and feed it into the wire tube, achieving automatic threading. The straightening device straightens bent wires, ensuring that straight wires do not get stuck in the wire tube, thus improving work efficiency and reducing labor intensity. However, there is no auxiliary guide structure at the end of the wire. When the wire is inserted into the pipe, the pipe is arranged in a curved and irregular shape. When the drive structure at the front end causes the wire to be automatically threaded, the wire is affected by the curved and irregular shape of the pipe, which will cause the wire to bend and block inside the pipe. In addition, there are many protruding particles on the inner wall of the pipe. When the wire passes through the pipe, it will cause wear on the side wall of the wire and reduce the service life of the wire.

[0004] Based on this, the present invention provides an automatic wiring device for electrical wires used in building decoration to solve the problems mentioned in the background art. Summary of the Invention

[0005] This invention addresses the technical problems existing in the prior art by providing an automatic wiring device for electrical wires in building decoration.

[0006] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an automatic wire threading device for building decoration, comprising a pole body, a positioning sleeve fixedly sleeved on the outer ring of the pole body, annular grooves opened at the top and bottom of the positioning sleeve, an embedded telescopic plate embedded in the inner side of the positioning sleeve, a clamp fixedly connected to the side wall of the embedded telescopic plate, a spring telescopic rod fixedly connected to the side wall of the positioning sleeve, and a guide mechanism provided on the inner side of the clamp and the side wall of the spring telescopic rod; The outer ring of the rod is provided with a grinding mechanism; A wire harness mechanism is provided at the bottom of the rod; A buffer mechanism is provided at the top of the rod.

[0007] The beneficial effects of adopting the above-mentioned further solution are as follows: Positioning sleeve one and positioning sleeve two are fixedly fitted on the outer ring of pole body 1; a wire-binding mechanism is installed at the bottom; and a buffer mechanism is installed at the top, providing an installation reference for all functional components; the length of pole body 1 can be designed according to the pipe length to ensure coverage of wiring needs in different decoration scenarios; positioning sleeve one is fixedly fitted on the outer ring of the pole body; annular slots are opened at the top and bottom to assist in fixing other components; an embedded telescopic plate is embedded on the inner side, which can adjust the extension length according to the pipe diameter to adapt to pipes of different sizes; and a spring telescopic rod is fixed to the side wall to guide... The guide wheel provides elastic support, ensuring that the guide wheel always fits against the inner wall of the pipe. Annular grooves are located at the top and bottom of the positioning sleeve. It can cooperate with other components to lock the positioning sleeve on the rod, preventing it from sliding during operation and ensuring stable operation of the guiding mechanism. The embedded telescopic plate is an adjustable component of the guiding mechanism, embedded inside the positioning sleeve, with a fixed clamp on the side wall. It can extend and retract radially along the positioning sleeve, adjusting the distance between the clamp and the rod to accommodate pipes of different diameters. After extension and retraction, the position can be locked with bolts to ensure it does not loosen during operation.

[0008] The beneficial effects of this invention are: 1) This invention features a guide mechanism located on the upper part of the outer wall of the rod. This guide mechanism can automatically thread the wire according to the size of the inner wall of the pipe. The guide mechanism adopts a four-guide wheel structure, which can improve the threading efficiency during automatic wire threading and minimize the occurrence of bending and blockage during the threading process. The guide mechanism uses an embedded telescopic plate and a clamp to adjust the guide wheel connector, which facilitates effective adjustment of the inner diameter of the pipe. The spring telescopic rod can reduce the pressure of the guide wheel on the inner wall of the pipe, and its buffering effect can reduce wear on the inner wall of the pipe and improve its service life. At the same time, the guide mechanism is fixed with a nut and a threaded edge after adjustment, making the operation more convenient.

[0009] 2) This invention utilizes a grinding mechanism located on the outer wall of the rod and at the bottom of the guide wheel. This mechanism adjusts with the expansion of the guide wheel. The expansion distance is further adjusted via a groove and slider at the bottom of the rotating seat, allowing the pre-designed mounting strip and abrasive plate to fit into multiple limiting mounting slots. The grinding mechanism is adjusted and fixed via a rotatable telescopic rod, which extends the distance of the arc-shaped frame and secures it with bolts. During adjustment, a rotatable arc-shaped rotating plate limits the mounting strip, preventing it from wobbling or falling off. The abrasive plate always protrudes beyond the arc-shaped rotating plate and remains at the same horizontal plane as the guide wheel, enabling effective grinding while the wire is being threaded, thus improving the wire's lifespan.

[0010] 3) This invention utilizes a wire-binding mechanism at the bottom of the rod body. This mechanism can position and fix the wires, employing a highly elastic and tough elastic clamping sleeve to hold and fix the wires. The pre-designed elastic clamping sleeve is adapted to the wire diameter, effectively and stably clamping the wires and preventing them from easily falling off. At the same time, the wire-binding mechanism uses a magnetic structure to fix the elastic clamping sleeve and the positioning cylinder. The deep magnetic ring groove design prevents the magnetic ring plate from falling off when it moves at high speed inside. After the wire is threaded, the positioning cylinder can be pulled out by the handle and the wire can be removed, making it more portable.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the guiding mechanism includes an extended arc-shaped plate located inside the jacket and on the side wall of the spring telescopic rod. A rotating seat is fixedly provided on the side wall of the extended arc-shaped plate, and a guide wheel is rotatably connected to the inner side of the rotating seat.

[0013] Furthermore, the outer ring of the rod body is provided with a threaded edge, and a nut is threadedly fitted onto the outer ring of the threaded edge. An annular retaining plate is welded to the bottom of the nut.

[0014] The beneficial effects of adopting the above-mentioned further solution are as follows: the jacket serves as the clamping and fixing structure for the top and bottom of the extended arc plate, and is the main fixing connection structure for the extended arc plate. The jacket is adjusted by the embedded telescopic plate, so that the four extended arc plates always maintain an annular structure that allows the installation strip to be installed after adjustment. The spring telescopic rod is the main buffer connecting component of the extended arc plate. During wire threading, the guide wheel continuously adheres to the inner wall of the pipe, and the extrusion force it experiences can be effectively buffered by the spring telescopic rod, reducing the extrusion force on the inside of the pipe and improving the service life of the pipe. The rotating seat is used to assist the guide wheel in operation, and there are four of them. The threaded edge is designed at two points on the outer wall of the rod, located at the upper and lower points of the positioning sleeve. The nuts are threaded onto the outer ring of the threaded edge. After adjustment by the embedded telescopic plate, the annular clamping plate is moved down into the annular groove by rotating the nuts to keep the threads pressed and fixed.

[0015] Furthermore, the grinding mechanism includes a positioning sleeve two fixedly sleeved on the outer ring of the rod, a rotating seat two fixedly connected to the side wall of the positioning sleeve two, a telescopic rod rotatably connected to the inner side of the rotating seat two, and a bolt threadedly connected to the side wall of the telescopic rod.

[0016] Furthermore, the polishing mechanism also includes a groove formed at the bottom of the rotating seat, a slider is slidably connected to the inner side of the groove, and an arc-shaped frame is fixedly connected to the bottom of the slider.

[0017] Furthermore, a limiting installation groove is provided on the inner side of the arc-shaped frame, a connecting seat is welded to the bottom of the arc-shaped frame, a rotating shaft is fixedly connected to the bottom of the connecting seat, rotating plates are rotatably connected to both ends of the rotating shaft, a receiving plate is fused between the rotating plates, a lifting seat is fixedly connected to the top of the receiving plate, an arc-shaped rotating plate is fixedly connected to the top of the lifting seat, an installation strip is provided on the inner side of the limiting installation groove, and a frosted sheet is connected to the side wall of the installation strip.

[0018] Furthermore, a rotating seat three is fixedly connected to the bottom of the arc-shaped frame, and the inner side of the rotating seat three is rotatably connected to the telescopic rod.

[0019] The beneficial effects of adopting the above-mentioned further solution are as follows: the second positioning sleeve is located below the first positioning sleeve, providing installation space and cooperating with the installation of the second rotating seat. The second rotating seat has four positions for rotating the telescopic rod, thereby cooperating with the third rotating seat to adjust the telescopic distance of the telescopic rod. Its bolts are used for threaded tightening and fixing after the telescopic rod is adjusted; the slide groove is opened at the bottom of the first rotating seat, which is used to cooperate with the slider to allow the arc frame to cooperate with the guide wheel for equal distance adjustment, always keeping the guide wheel and the installed grinding disc at the same level, so as to achieve effective grinding effect while being able to guide; the limiting installation groove is the main embedding of the installation strip. The mounting strip and abrasive disc can be designed according to the pre-designed inner diameter of the pipe, so that they can be installed precisely on the inner wall of the limiting mounting groove. The connecting seat is used to increase the installation distance, so that the installed rotating shaft can be adjusted in conjunction with the rotating plate, avoiding structural interference. The receiving plate and lifting seat are used to cooperate with the installation of the arc-shaped rotating plate, so that the arc-shaped rotating plate can be attached to the outer wall of the mounting strip during rotation adjustment. The arc-shaped rotating plate is adjusted by rotating the telescopic rod. After adjustment, it is fixed with bolts. The rotating seat three is used to cooperate with the rotating seat two to adjust the telescopic rod, so that the telescopic rod can be effectively adjusted.

[0020] Furthermore, the wire harness mechanism includes a groove formed at the bottom of the rod body, a positioning cylinder embedded in the inner side of the groove, a fixing ring fixedly sleeved on the outer ring of the positioning cylinder, a magnetic ring plate fixedly installed at the bottom of the fixing ring, an elastic clamping sleeve fixedly laid on the inner side of the positioning cylinder, and a handle fixedly connected to the bottom of the fixing ring.

[0021] Furthermore, the wire harness mechanism also includes a magnetic ring groove formed at the bottom of the rod, wherein the magnetic ring groove and the magnetic ring plate attract each other without repelling each other.

[0022] The beneficial effects of adopting the above-mentioned further solution are that the groove is the main installation position of the wire harness mechanism, the positioning cylinder and the elastic clamping sleeve are the main clamping positions of the wire, and the elastic clamping sleeve is made of a highly elastic and tough material, which can clamp the wire with high strength. The fixing ring is used to expand the installation space of the positioning cylinder, so that the magnetic ring plate can be adjusted up and down in conjunction with the fixing ring and the elastic clamping sleeve, thereby magnetically attracting the magnetic ring plate inside the magnetic ring groove and keeping it fixed in the groove, which can prevent the wire from falling off during high-speed wire threading. The handle is used to pull out the positioning cylinder, thereby facilitating the subsequent removal of the wire.

[0023] Furthermore, the buffer mechanism includes a counterweight head fixedly mounted on the top of the rod, and a rubber pad is fixedly connected to the top of the counterweight head.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the counterweight head is designed at the top of the pole to increase the weight at the top of the pole. After the entire pole passes through the pipe, when the distance at the exit point is relatively high, the counterweight head at the top of the pole will fall first due to the influence of gravity. At the same time, the rubber pad is used for auxiliary cushioning, thereby reducing the force on the entire equipment to hit the ground and improving the service life of the equipment.

The positioning sleeve 4 and positioning sleeve 5 are fixedly fitted around the outer ring of the pole 1. A wire-binding mechanism is provided at the bottom, and a buffer mechanism is installed at the top, providing an installation reference for all functional components. The length of the pole 1 can be designed according to the pipe length to ensure coverage of wiring needs in different decoration scenarios. The positioning sleeve 4 is fixedly fitted around the outer ring of the pole 1, with annular grooves 44 at its top and bottom for... The inner side is fitted with an embedded telescopic plate 45, which can be adjusted according to the pipe diameter to adapt to pipes of different sizes. A spring telescopic rod 412 is fixed on the side wall to provide elastic support for the guide wheel 43, ensuring that the guide wheel 43 is always in contact with the inner wall of the pipe. An annular groove 44 is opened at the top and bottom of the positioning sleeve 4; it can cooperate with other components to lock the position of the positioning sleeve 4 on the rod 1, preventing the positioning sleeve 4 from sliding during equipment operation and ensuring the stable operation of the guiding mechanism. The embedded telescopic plate 45 is an adjustable component of the guiding mechanism, embedded in the inner side of the positioning sleeve 4. A clamp 46 is fixed on the side wall; it can extend and retract radially along the positioning sleeve 4 to adjust the distance between the clamp 46 and the rod 1, thereby adapting to pipes of different diameters and ensuring that it does not loosen during operation.

[0029] A guide mechanism is provided on the inner side of the sleeve 46 and the side wall of the spring telescopic rod 412. The guide mechanism includes an extended arc-shaped plate 41 located on the inner side of the sleeve 46 and the side wall of the spring telescopic rod 412. A rotating seat 42 is fixedly provided on the side wall of the extended arc-shaped plate 41. A guide wheel 43 is rotatably connected to the inner side of the rotating seat 42. A threaded edge 49 is provided on the outer ring of the rod body 1. A nut 410 is threaded on the outer ring of the threaded edge 49. An annular clamping plate 411 is welded to the bottom of the nut 410. The sleeve 46 is the clamping and fixing structure for the top and bottom of the extended arc-shaped plate 41 and is the main fixing connection structure for the extended arc-shaped plate 41. The sleeve 46 is adjusted by the embedded telescopic plate 45 so that the four extended arc-shaped plates 41 are always kept in place after adjustment. The ring structure for mounting the installation strip 512 is provided. The spring telescopic rod 412 is the main buffer connector for extending the arc plate 41. During the wire threading process, the guide wheel 43 continuously adheres to the inner wall of the pipe for wire threading. The pressure it experiences can be effectively buffered by the spring telescopic rod 412, reducing the pressure on the inside of the pipe and improving the service life of the pipe. The rotating seat 42 is used to assist the guide wheel 43 in operation and has four locations. The threaded edge 49 is designed at two locations on the outer wall of the rod body 1, located at the upper and lower locations of the positioning sleeve 4. The nuts 410 are threaded onto the outer ring of the threaded edge 49. After the embedded telescopic plate 45 is adjusted, the annular retaining plate 411 is moved down into the annular retaining groove 44 by rotating the nut 410 to keep the threads pressed and fixed.

[0030] The outer ring of the rod body 1 is equipped with a grinding mechanism, which includes a positioning sleeve 2 5 fixedly sleeved on the outer ring of the rod body 1. A rotating seat 2 510 is fixedly connected to the side wall of the positioning sleeve 2 5. A telescopic rod 51 is rotatably connected to the inner side of the rotating seat 2 510. A bolt 52 is threadedly connected to the side wall of the telescopic rod 51. The grinding mechanism also includes a sliding groove 47 opened at the bottom of the rotating seat 1 42. A slider 48 is slidably connected to the inner side of the sliding groove 47. An arc frame 53 is fixedly connected to the bottom of the slider 48. A limit mounting groove 514 is opened on the inner side of the arc frame 53. A connecting seat 54 is welded to the bottom of the arc frame 53.

A receiving plate 57 is welded between the rotating plates 56. A lifting seat 58 is fixedly connected to the top of the receiving plate 57. An arc-shaped rotating plate 59 is fixedly connected to the top of the lifting seat 58. An installation strip 512 is provided inside the limiting installation groove 514. A frosted sheet 513 is connected to the side wall of the installation strip 512. A rotating seat 511 is fixedly connected to the bottom of the arc-shaped frame 53. The inner side of the rotating seat 511 is rotatably connected to the telescopic rod 51. Positioning sleeve 510 is located below positioning sleeve 4 to provide installation space for the installation of rotating seat 510. There are four rotating seats 510 in total. The telescopic rod 51 is rotated and installed, thereby cooperating with the rotating seat 3 511 to adjust the telescopic distance of the telescopic rod 51. The bolt 52 is used to tighten the thread after the telescopic rod 51 is adjusted. The slide groove 47 is opened at the bottom of the rotating seat 1 42, which is used to cooperate with the slider 48 to enable the arc frame 53 to cooperate with the guide wheel 43 to adjust the distance at the same time, always keeping the guide wheel 43 and the installed abrasive plate 513 at the same level, so as to achieve effective grinding effect while guiding. The limiting installation groove 514 is the main embedding position of the installation strip 512. The installation strip 512 and the abrasive plate 513 can be designed according to the pre-designed inner diameter of the pipe. This allows it to be installed precisely on the inner wall of the limiting installation groove 514. The connecting seat 54 is used to increase the installation distance, so that the installed rotating shaft 55 can be adjusted in conjunction with the rotating plate 56, avoiding structural interference. The receiving plate 57 and the lifting seat 58 are used to cooperate with the installation of the arc-shaped rotating plate 59, so that the arc-shaped rotating plate 59 can be attached to the outer wall of the mounting strip 512 during rotation adjustment. The arc-shaped rotating plate 59 is adjusted by rotating the telescopic rod 51. After adjustment, it is fixed by bolts 52. The rotating seat 3 511 is used to cooperate with the rotating seat 2 510 to adjust the telescopic rod 51, so that the telescopic rod 51 can be effectively adjusted.

[0031] A wire-binding mechanism is provided at the bottom of the rod body 1. The wire-binding mechanism includes a groove 6 at the bottom of the rod body 1, a positioning cylinder 62 embedded in the inner side of the groove 6, a fixing ring 61 fixedly sleeved on the outer ring of the positioning cylinder 62, a magnetic ring plate 63 fixedly installed at the bottom of the fixing ring 61, an elastic clamping sleeve 65 fixedly laid on the inner side of the positioning cylinder 62, and a handle 66 fixedly connected to the bottom of the fixing ring 61. The wire-binding mechanism also includes a magnetic ring groove 64 at the bottom of the rod body 1. The magnetic ring groove 64 and the magnetic ring plate 63 attract each other but do not repel each other. The groove 6 is the main installation position of the wire-binding mechanism. The positioning cylinder 62 and the elastic clamping sleeve 65 are the main clamping positions for the wire. The elastic clamping sleeve 65 is made of a highly elastic and tough material, which can clamp the wire with high strength. The fixing ring 61 is used to expand the installation space of the positioning cylinder 62, so that the magnetic ring plate 63 can be adjusted up and down in conjunction with the fixing ring 61 and the elastic clamping sleeve 65, thereby magnetically attracting the magnetic ring plate 63 inside the magnetic ring groove 64 and keeping it fixed in the groove 6. This can prevent the wire from falling off during high-speed threading. The handle 66 is used to pull out the positioning cylinder 62, which makes it convenient to remove the wire later.

[0032] A buffer mechanism is provided at the top of the rod 1. The buffer mechanism includes a counterweight head 2 fixedly installed at the top of the rod 1. A rubber pad 3 is fixedly connected to the top of the counterweight head 2. The counterweight head 2 is designed at the top of the rod 1 to increase the weight at the top of the rod 1. After the entire rod 1 passes through the pipe, when the distance at the exit point is relatively high, the counterweight head 2 at the top of the rod 1 will fall first due to the influence of gravity. At the same time, the rubber pad 3 is used for auxiliary buffering, thereby reducing the force on the entire equipment when it hits the ground and improving the service life of the equipment.

[0033] The working principle of this invention is as follows: When using this device, first pull the handle 66 to pull out the fixing ring 61, positioning cylinder 62, elastic clamping sleeve 65 and magnetic ring plate 63. Then insert the wire into the elastic clamping sleeve 65. Due to the high elasticity and toughness, the wire is clamped and fixed. Then insert the fixing ring 61, positioning cylinder 62, elastic clamping sleeve 65 and magnetic ring plate 63 into the groove 6 and magnetic ring groove 64 to maintain adsorption and fixation. During the threading operation, the guide wheel 43 and the arc frame 53 are expanded and adjusted according to the diameter of the pipe. During this process, the four rotating seats 42 are pulled to expand, so that the rotating seats 42 are adjusted in distance under the action of the embedded telescopic plate 45. The guide wheel 43 stops after it can be attached to the inner wall of the pipe. Then, the nut 410 is manually turned so that it starts to adjust the thread under the action of the threaded edge 49, so that the annular plates 411 at the top and bottom are engaged with the bottom of the annular groove 44 and pressed against the embedded telescopic plate 45 located at the movable end inside the annular groove 44. When adjusting the grinding distance, pull the arc frame 53. Under the action of the slide groove 47, slider 48, rotating seat 2 510, rotating seat 3 511 and telescopic rod 51, the arc frame 53 expands and adjusts. After adjusting to the appropriate distance, the mounting strip 512 is embedded in the four limiting mounting grooves 514. Then, rotate the receiving plate 57 and the lifting seat 58 so that the arc rotating plate 59 is attached to the mounting strip 512 and pressed and fixed under the action of the rotating shaft 55. Then tighten the bolt 52 to tighten it. During the threading process, the drive device at the front end pushes the wire through the conduit. After the threading is completed, the rubber pad 3 will be affected by the weight of the counterweight head 2. When there is a height difference, the rubber pad 3 will land first, reducing its downward pressure and improving its service life.
