Description
Technical Field
[0001] The invention belongs to the technical field of construction engineering equipment, and in particular relates to a wire threading auxiliary device for building water and electricity construction. Background Art
[0002] To ensure circuit safety and facilitate subsequent maintenance during plumbing and electrical installation, electrical wiring must be routed through conduit pre-buried in the wall. This not only minimizes exposure to the wires, reducing the risk of damage and accidental collisions, but also avoids potential electrical safety hazards posed by exposed wiring. Because circuits must be flexibly arranged to meet specific needs, flexible wires are predominantly used in construction. However, during plumbing and electrical installation, flexible wires can become stuck inside the conduit, making it difficult to thread the wires through the conduit. This is especially challenging when the conduit has curves, leading to the need to segment the wiring into multiple, preferably straight, sections. Each section is then individually threaded and connected sequentially. However, segmenting the wiring into multiple sections increases the number of connections, increasing the risk of poor electrical connections.
[0003] At present, when carrying out water and electricity construction in buildings, steel wire leads or electric threading machines are often used to assist in threading. The steel wire lead is first passed through the wire tube manually or electrically. Since the steel wire lead itself has good strength and toughness, it can smoothly pass through the bend and out of the wire tube, and then the steel wire lead is used to pull the wire through the wire tube. The wires in the wire tube include the neutral wire, the live wire, the ground wire, and other wires added according to the circuit design. When using the steel wire lead to assist in threading, the construction workers will tie the ends of multiple wires together and then connect the multiple wires to the steel wire lead. However, during the threading construction process, multiple wires that are tied and fixed together often become tangled together after passing through the wire tube, causing the circuit to heat up severely during use.
[0004] After research, it was found that when the wires pass through the wire tube, they will rub against the inner wall of the wire tube, and the multiple wires tied together will interact with each other under the influence of friction and then get entangled together. In order to prevent the wires from getting entangled with each other after passing through the wire tube and affecting the safety of the circuit, a connecting ring is often set at the end of the wire lead, and the multiple wires are tied separately to the connecting ring one by one to avoid the interaction between the wires during threading and prevent the wires from getting entangled with each other. However, during the construction process, it was found that the friction between the wires near the inside of the bend and the connection between the wires and the wire lead was more intense than that between other wires and the wire tube, and the wires were all connected to the wire lead individually. The wires could not share the resistance caused by friction, resulting in the wires near the inside of the bend being prone to falling off from the wire lead. Once the wires fall off, all the wires need to be withdrawn from the wire tube and rethreaded, resulting in poor threading effect using wire leads or electric threading machines.

[0024] The present invention provides a wire threading auxiliary device for building water and electricity construction. Figures 1 to 7 The present invention is described with reference to a structural schematic diagram of FIG.
[0025] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solutions of the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present invention.
[0026] Water and electricity are essential infrastructures in modern buildings, playing a vital role in the functionality, comfort, safety, and sustainability of buildings. They support the daily operations of buildings and ensure the normal functioning of residential, working, and commercial environments.
[0027] After research, it was found that when the wires pass through the wire tube, they will rub against the inner wall of the wire tube, and the multiple wires tied together will interact with each other under the influence of friction and then get entangled together. In order to prevent the wires from getting entangled with each other after passing through the wire tube and affecting the safety of the circuit, a connecting ring is often set at the end of the wire lead, and the multiple wires are tied separately to the connecting ring one by one to avoid the interaction between the wires during threading and prevent the wires from getting entangled with each other. However, during the construction process, it was found that the friction between the wires near the inside of the bend and the connection between the wires and the wire lead was more intense than that between other wires and the wire tube, and the wires were all connected to the wire lead individually. The wires could not share the resistance caused by friction, resulting in the wires near the inside of the bend being prone to falling off from the wire lead. Once the wires fall off, all the wires need to be withdrawn from the wire tube and rethreaded, resulting in poor threading effect using wire leads or electric threading machines.
[0028] Based on the above problems, an embodiment of the present invention provides a wire threading auxiliary device for construction water and electricity construction. By cooperating with a fixing piece, a connecting piece, a clamping mechanism and a ball, multiple wires can be inserted into the wiring countersunk holes on the connecting piece respectively, and then the clamping mechanism is used to fix the wires, so that when the steel wire lead is pulled by the fixing piece to pass the connecting piece and the multiple wires through the wire tube, direct contact and friction between the connection between the connecting piece and the wire and the inner wall of the wire tube is avoided. At the same time, the fixing piece is used to enable the connecting piece and the multiple wires to deflect left and right around the center line of the steel wire lead. When the ball and When the ball abuts the inner wall of the wire tube, the connector can deflect around its circumference, thereby adjusting the positions of multiple wires, avoiding the wires close to the inner side of the wire tube bend always rubbing against the inner wall of the wire tube, thereby preventing the wires and the wire lead from falling off during threading, and when the ball does not abut against the inner wall of the wire tube, the connector can remain stable without deflecting, avoiding excessive deflection that causes the wires to be entangled, and improving the effect of using a wire lead or an electric threading machine to assist in threading. The threading auxiliary device of the present invention is easy to use, effective, and practical, and is worthy of promotion.
[0029] Reference Figure 1 , Figure 1 This is a front view of the threading auxiliary device of this embodiment, as shown Figure 1 As shown, a wire threading auxiliary device for building water and electricity construction is configured to be connected to a steel wire lead 10 and is used to connect the steel wire lead 10 with multiple wires 11 so that the steel wire lead 10 pulls the wires 11 through the wire tube, including a fixing member 1, which is fixed to the end of the steel wire lead 10, a connecting member 2 is provided at the end of the fixing member 1 away from the steel wire lead 10, the connecting member 2 is coaxial with the center line of the fixing member 1, one end of the connecting member 2 is rotatably connected to the fixing member 1, and the other end is equidistantly surrounded by a plurality of wiring countersunk holes 21, and the wiring countersunk holes 21 are arranged along the center line direction of the connecting member 2. Figure 2 , Figure 2 This is a right side view of the threading auxiliary device of this embodiment, as shown in FIG. Figure 2 As shown, the wires 11 are inserted into the wiring countersunk holes 21 one by one, thereby separating the multiple wires 11. Multiple clamping mechanisms are arranged in the wiring countersunk holes 21 one by one, for clamping and fixing the wires 11 inserted into the wiring countersunk holes 21. Multiple balls 3 are arranged on the outer wall of the connector 2 at equal intervals. The balls 3 correspond to the wiring countersunk holes 21 one by one and are respectively located on the outside thereof. The balls 3 are rotatably connected to the connector 2. When the balls 3 abut against the inner wall of the wire tube, the connector 2 deflects around its circumference to adjust the positions of the multiple wires 11.
[0030] The wire threading auxiliary device in this embodiment needs to be used in conjunction with the wire lead or the wire lead of an electric wire threading machine when in use. When the wire wrapped lead is passed through the wire tube manually or electrically, the fixing part 1 of the wire threading auxiliary device is connected to the end of the wire lead 10, and one end of the wire 11 to be passed through the wire tube is respectively inserted into the wiring countersunk hole 12. After the wire 11 inserted into the wiring countersunk hole 12 is fixed by the clamping mechanism, the wires 11 are driven into the wire tube by the wire lead 10 to thread the wires. Since the joint position of the wire 11 and the connector 2 is in the wiring countersunk hole 12, the joint position is avoided during the threading process. The connector 2 is placed in direct contact and friction with the inner wall of the wire tube. At the same time, when the auxiliary device approaches the bend of the wire tube during the threading process, a ball on the connector 2 will gradually abut against the inner wall of the wire tube near the inner side of the bend. Since there is only one ball abutting against the inner wall of the wire tube, the connector 2 itself is unstable due to the friction between the wire 11 and the inner wall of the wire tube, and will deflect to either side, thereby adjusting the position of the wire 11, avoiding that only one wire 11 is always in intense friction with the inner wall of the wire tube (the inner wall of the wire tube near the inner side of the bend) during the threading process, so that multiple wires 11 are taken turns to be in a position close to the inner side of the bend.
[0031] The threading auxiliary device in this embodiment utilizes the deflection property of the ball and the connector 2 (due to the friction between the wire 11 and the inner wall of the wire tube) to enable the connector 2 to adjust the position of the wire 11 to a certain extent. In particular, when the auxiliary device passes through a bend in the wire tube, when a ball 3 on the connector 2 abuts the inner wall inside the bend, the connector 2 becomes more unstable and deflects, thereby achieving the replacement of another wire 11 to a position close to the inner side of the bend after passing the bend, and when the connector 2 deflects to a certain position, the ball on the connector 2 leaves the position close to the inner side of the bend, so that the connector 2 abuts the inner wall of the wire tube, so that the connector 2 remains stable for a period of time, and the above process will be repeated when passing the next bend. At the same time, due to the previous deflection, the wire itself has an opposite torsional force, and the next time it will deflect in the opposite direction, so that multiple wires are replaced back and forth and rub against the inner wall of the wire tube near the inner side of the bend, thereby ensuring that the wire 11 can pass through the wire tube smoothly.
[0032] Reference Figure 6 , Figure 6 This is a CC cross-sectional view of the threading auxiliary device of this embodiment, as shown in FIG. Figure 6 As shown, the clamping mechanism in this embodiment includes a splint 4, a rotating shaft 5, a toothed disc 6, a cavity 20, and a rack 7. The splint 4 is arranged in the wiring countersunk hole 21 and is slidably connected to the connector 2 along the radial direction. A cavity 20 is opened inside the side of the connector 2 close to the wiring countersunk hole 21. The cavity 20 is located on the inner side of multiple wiring countersunk holes 21. The cavity 20 is coaxial with the center line of the connector 2. The connector 2 is located on the side where multiple wiring countersunk holes 21 are close to each other and is penetrated by a rack 7. The rack 7 is slidably connected to the connector 2 along the radial direction. One end of the rack 7 is fixedly connected to the splint 4, the rotating shaft 5 is arranged in the cavity 20 and is coaxial with it. The rotating shaft 5 is rotatably connected to the connector 2, the toothed disc 6 is fixed on the rotating shaft 5, one end of the rack 7 extends into the cavity 20, and the rack 7 engages with the toothed disc 6.
[0033] In this embodiment, the rotating shaft 5 in the cavity 20 can drive the toothed disc 6 to rotate, thereby driving the rack 7 to move back and forth along the radial direction of the connecting member 2, thereby driving the clamping plate 4 to move. When the clamping plate 4 moves toward the inner wall on the side close to the wire 11, the wire 11 can be gradually clamped and fixed.
[0034] The clamping mechanism in this embodiment can fix multiple wires 11 at the same time, avoiding repeated disassembly and installation of the wires, thereby improving ease of use.
[0035] In addition, in this embodiment, the cavity 20 is located on the side of the connecting member 2 away from the fixing member 1 and is set through. A cavity cover plate 201 is set at the through end. The cavity cover plate 201 is fixedly connected to the connecting member 2 by threaded fasteners. The outer side of the cavity cover plate 201 is flush with the connecting member 2. One end of the rotating shaft 5 passes through the cavity cover plate 201 and is rotatably connected to it. The end of the rotating shaft 5 located on the outer side of the cavity cover plate 201 is a bolt head, which is convenient for construction personnel to use tools to drive the rotating shaft 5 to rotate, further improving the convenience of threading operations.
[0036] As a further optimization scheme, in this embodiment, a plurality of slide grooves 22 are evenly spaced around one side of the connecting member 2 close to the fixing member 1. The slide grooves 22 are arranged along the radial direction of the connecting member 2. The slide grooves 22 correspond one to one with the wiring countersunk holes 21 and are perpendicular to each other. A slider 23 is provided in the slide groove 22 and is slidably connected thereto. The balls 3 are respectively arranged at one end of the slider 23 away from each other. The balls 3 are rotatably connected to the slider 23. A driving mechanism is provided on the connecting member 2, and the output end of the driving mechanism is connected to the slider 23 to drive the slider 23 to move along the slide groove 22.
[0037] In this embodiment, the groove 22, slider 23 and driving mechanism on the connecting member 2 are used in conjunction to change the position of the ball 3 in the radial direction of the connecting member 2. When the connecting member 2 is close to the bend of the wire tube, the driving mechanism is used to drive the slider 23 to move to the outside of the groove 22, so that the ball 3 actively abuts against the inner wall of the wire tube near the inner side of the bend, increasing the distance between the inner wall inside the bend and the connecting member 2, and increasing the probability of the connecting member 2 deflecting due to instability caused by friction between the wire 11 and the inner wall of the wire tube, thereby causing the connecting member 2 to deflect, increasing the number of times the connecting member 2 adjusts the position of the wire 11, preventing the wire and the wire lead from falling off during threading, and further improving the effect of using a wire lead or an electric threading machine to assist in threading.
[0038] In addition, in this embodiment, when the slider 23 and the ball 3 are used to increase the distance between the connector 2 and the inner wall of the wire tube, the friction resistance of the wire 11 close to the connector 2 can also be reduced, thereby preventing the wire and the wire lead from falling off during threading, and further improving the effect of using a wire lead or an electric threading machine to assist in threading.
[0039] Reference Figure 4 , Figure 4 FIG. 2 is a cross-sectional view of the threading auxiliary device according to the embodiment of the present invention. Figure 4 As shown, as a further optimization scheme, the driving mechanism in this embodiment includes a mounting countersunk hole 24 and an inclined surface. The mounting countersunk hole 24 is opened at the end of the connector 2 away from the wiring countersunk hole 21 and is coaxial with the center line of the connector 2. The end of the fixing member 1 away from the wire lead 10 extends into the mounting countersunk hole 24. The fixing member 1 is slidably connected to the connector 2 along the circumferential and axial directions. The slide groove 22 is connected to the mounting countersunk hole 24. The inclined surface is provided on the side of the slider 23 close to the fixing member 1. The width of the slider 23 gradually decreases from the end close to the ball 3 to the other end, and the fixing member 1 abuts against the inclined surface.
[0040] In this embodiment, the mounting countersunk hole 24 provided on the connector 2 allows the wire threading auxiliary device to slide into the mounting countersunk hole 24 when passing through a bend in the wire tube because the wire lead and the fixing member will tilt toward the inside of the bend. The friction between the fixing member 1 and the inside of the bend can be utilized to make the fixing member 1 slide into the mounting countersunk hole 24, and then the fixing member 1 cooperates with the inclined surface on the slider 23 to drive the slider 23 to move toward the outside of the slide groove 22, so that the slider 23 drives the ball 3 to actively move toward the inner wall of the wire tube, so that when passing through a bend in the wire tube, the connector 2 is deflected to adjust the position of the wire. In the straight stage of the wire tube, the fixing member 1 remains stationary, so that the ball is in its original position, which is beneficial to maintaining the stability of the connector 2 itself and avoiding excessive deflection that causes the wires to be entangled.
[0041] Reference Figure 5 , Figure 5BB is a cross-sectional view of the threading auxiliary device of this embodiment, as shown in FIG. Figure 5 As shown, as a further optimization solution, the driving mechanism in this embodiment also includes multiple first elastic members 25, and the multiple first elastic members 25 are radially arranged at the bottom thereof with the center line of the mounting countersunk hole 24 as the center. One end of the first elastic member 25 is connected to the connecting member 2, and the other end is connected to the slider 23.
[0042] In this embodiment, the first elastic member 25 is used to restore the slider 23 to its original position after the auxiliary threading device passes through a curve, and the fixing member 1 is restored to its original position by the pulling of the wire lead, so that the connecting member 2 can remain relatively stable in the straight stage.
[0043] In this embodiment, four guide grooves are radially opened at the bottom of the mounting countersunk hole 24, and a connecting rod is provided in the guide groove. One end of the connecting rod extends into the slide groove 22 and is fixedly connected to the slider 23, and the other end is fixed with a limit block. The first elastic member 25 is a spring, which is sleeved on the connecting rod located in the guide groove.
[0044] As a further optimization scheme, in this embodiment, a plurality of grooves 26 are provided around the end of the connecting member 2 away from the fixing member 1 at equal intervals. The grooves 26 are arranged one-to-one corresponding to the slide grooves 22. A limiting plate 27 is provided in the groove 26. The limiting plate 27 is slidably connected to the groove 26 along the length direction. A transmission mechanism is provided on the connecting member 2. The input end of the transmission mechanism is connected to the slider 23, and the output end thereof is connected to the limiting plate 27.
[0045] In this embodiment, the limit plate 27 in the groove 26 is used in conjunction with the transmission mechanism, so that when the auxiliary threading device passes through a curve, the slider 23 can be used to drive the limit plate 27 to extend out of the groove 26, and the wire 11 is wrapped near the side connected to the connector 2, thereby avoiding direct contact and severe friction between the side of the wire 11 near the connection with the connector 2 and the inner wall of the wire tube, preventing the wire and the wire lead from falling off during threading, and further improving the effect of using a wire lead or an electric threading machine to assist in threading.
[0046] As a further optimization solution, in this embodiment, the distance between the sink 26 and the center line of the connecting member 2 gradually decreases from one end close to the fixing member 1 to the other end.
[0047] Reference Figure 7 , Figure 7 This is a schematic diagram of the wire threading auxiliary device of this embodiment for collecting wires, as shown in FIG. Figure 7As shown, in this embodiment, an inclined groove 26 is used so that after the limit plate 27 extends out of the groove 26, the side of the wire 11 connected to the connector 2 can be gathered toward the middle, further avoiding direct contact and severe friction between the side of the wire 11 connected to the connector 2 and the inner wall of the wire tube.
[0048] As a further optimization solution, in this embodiment, the longitudinal section of the limiting plate 27 is arc-shaped, and the center line of the limiting plate 27 is located inside the limiting plate 27 .
[0049] In this embodiment, the longitudinal section of the limiting plate 27 is set to be arc-shaped, which improves the effect of the limiting plate 27 on gathering the wires 11 and prevents the wires 11 from slipping out during gathering.
[0050] As a further optimization scheme, the transmission mechanism in this embodiment includes a guide rod 28, a wedge block 29 and a second elastic member 30. The connecting member 2 is located on the side of the sink groove 26 close to the slider 23 and is provided with a through hole. The through hole and the sink groove 26 are parallel to each other, and the through hole is connected to the slide groove 22. The wedge block 29 is fixed on the side of the slider 23 close to the sink groove 26. The guide rod 28 is passed through the through hole and is slidably connected to it. One end of the guide rod 28 is fixedly connected to the limit plate 27, and the other end abuts against the wedge block 29. The second elastic member 30 is sleeved on the guide rod 28 and is located in the sink groove 26.
[0051] In this embodiment, when the slider 23 moves toward the outside of the slide groove 22, it simultaneously drives the wedge block 29 to move, and the wedge block 29 and the guide rod 28 of the transmission mechanism drive the limit plate 27 to move. After the slider 23 returns to its original position, the second elastic member 30 is used to restore the limit plate 27 to its original position.
[0052] Reference Figure 3 , Figure 3 This is a left side view of the threading auxiliary device of this embodiment, as shown in FIG. Figure 3 As shown, as a further optimization solution, in this embodiment, the longitudinal section of the fixing member 1 is circular, and the outer diameter of the fixing member 1 gradually decreases from one end close to the connecting member 2 to the other end.
[0053] In this embodiment, the longitudinal cross-section of the fixing member 1 is circular, and its outer diameter gradually increases from one end close to the wire lead to the other end, so as to facilitate the fixing member 1 to move into the mounting countersunk hole 24 in an inclined posture.
[0054] In this embodiment, a countersunk limit cover plate 204 is provided on the outer side of the mounting countersunk hole 24. The countersunk limit cover plate 204 is fixedly connected to the connector 2 by threaded fasteners. A limit ring is arranged at one end of the fixing part 1 close to the connector 2. The countersunk limit cover plate 204 cooperates with the limit ring to limit the fixing part 1, and the outer side of the limit ring is arc-shaped, so that when the fixing part 1 abuts against the inner side of the curve, the fixing part 1 moves into the mounting countersunk hole 24 in an inclined posture, thereby only driving the slider 23 close to the inner side of the curve to move, further enhancing the instability of the connector 2 passing through the curve, so that it can be deflected and the position of the wire can be adjusted.
[0055] As a further optimization solution, in this embodiment, the outer diameter of the connecting member 2 gradually decreases from one side away from the fixing member 1 to the other side.
[0056] In this embodiment, a conical connector 2 is used, and the wiring countersunk hole 21 is arranged on an inclined surface, so that the entire threading auxiliary device can smoothly pass through the bend of the wire tube and avoid jamming during the threading process.
