Description

Technical Field

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

[0002] Conduit is primarily used to protect electrical wires and cables. It prevents wires and cables from being directly exposed to the elements, protecting them from mechanical damage, moisture erosion, and chemical corrosion, thus extending their lifespan. At the same time, conduit facilitates the laying and maintenance of electrical wires and cables, making wiring neater and more organized, and allowing maintenance personnel to quickly locate and troubleshoot line faults.

[0003] As disclosed in the patent announcement CN217334910U, a PE conduit for easy wire threading includes a conduit body, a sliding sleeve horizontally connected within the conduit body, a cable tray fixedly connected within the sliding sleeve, and a wire insertion hole within the cable tray. Limiting rings and limiting fixing rings are respectively inserted into the two ends of the conduit body. This invention allows multiple wires to be sequentially inserted into the wire insertion hole within the cable tray, separating and distinguishing them to avoid tangling. Pushing the wire to the left moves the cable tray and sliding sleeve to the left, contacting the limiting fixing ring. The wire can then be pulled out from the left end of the conduit body for easy threading. The limiting ring and limiting fixing ring are clamped within the conduit body by an inserted fastening rod, preventing the cable tray from detaching from the conduit body and facilitating the cable tray's guidance of the wires within the conduit body for threading. Simultaneously, the cable tray clamps and secures the wires within the conduit body.

[0004] While the above-mentioned solution achieves convenient cable threading and fixing through the separation area of ​​the threading hole, the limiting ring, and the limiting fixing ring, the utility model requires the limiting ring and the limiting fixing ring to be inserted into the fastening rod and clamped inside the threading tube to achieve the cable fixing effect, which is inconvenient. Furthermore, it lacks protective measures for cable entry and exit, which can easily lead to damage to the cable sheath due to friction with the hole during threading, affecting the cable's service life. Therefore, we propose an easy-to-thread threading tube that solves the protection problem for cable entry and exit in the utility model, as well as the inconvenience of the cable anti-derailment measures, improving the convenience and practicality of the utility model and extending the cable's service life. Utility Model Content

[0005] The purpose of this invention is to provide a conduit for easy threading, in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wire threading conduit includes a clamping tube, one end of which is threaded to a wire tube. The clamping tube has a clamping hole inside, and a clamping assembly is provided on the inner wall of the clamping hole. The wire tube has a wire hole inside, and an annular rubber protrusion is fixedly provided on the edge of the wire hole away from the end of the clamping tube. A ball bearing is embedded in the inner wall of the wire hole.

[0008] Furthermore, the clamping assembly includes a mounting groove, a U-shaped fixing block is fixedly disposed on the inner wall of the mounting groove, a clamping rod is hinged to the U-shaped fixing block, a rubber anti-slip layer is fixedly disposed on the surface of the clamping rod away from the U-shaped fixing block, and a return spring is connected between the side of the clamping rod near the U-shaped fixing block and the inner wall of the mounting groove.

[0009] Furthermore, the inner diameter of the wire hole is the same as the inner diameter of the clamping hole, the wire hole and the clamping hole correspond one-to-one, and there are five wire holes, which are symmetrical about the axis of the wire tube.

[0010] Furthermore, an annular groove is formed on the outer surface of the clamping tube and the wire tube, and a fixing component is movably installed inside the annular groove. The fixing component includes an annular retaining ring, and a mounting base is fixedly provided on the outer side of the annular retaining ring. The mounting base has a mounting through hole.

[0011] Furthermore, a first indicator arrow is fixedly provided on the outer surface of the clamping tube near the end of the wire tube, and a second indicator arrow is fixedly provided on the outer surface of the wire tube near the end of the clamping tube. The center lines of the first indicator arrow and the second indicator arrow are parallel to the central axis of the clamping tube and the wire tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This easy-to-thread conduit features an annular rubber protrusion at the edge of the wire hole away from the clamping tube, and several ball bearings embedded in the inner wall of the wire hole. The annular rubber protrusion not only provides guidance and positioning for the wire harness when entering the hole, but also prevents the wire harness from being scratched by the edge of the hole when it is inserted or withdrawn, thus avoiding damage to the outer sheath of the wire harness. The ball bearings reduce the frictional resistance of the inner wall of the wire hole, making wire harness threading smoother and faster, while also reducing the risk of friction damage to the wire harness and extending the service life of the cable.

[0014] 2. This easy-to-thread conduit, through a clamping component set inside the clamping hole, when the wire harness enters the clamping hole, the squeezing force generated on the clamping rod causes the return spring to contract. When the wire harness moves in the opposite direction of threading, the return spring drives the clamping rod to have a certain clamping force on the surface of the wire harness. Furthermore, the surface of the clamping rod is provided with a rubber anti-slip layer, which generates a large sliding resistance between the clamping rod and the surface of the wire harness, thereby achieving an automatic clamping effect on the wire harness. This avoids the problem of the wire harness slipping out of the slot and eliminates the inconvenience of workers having to take additional measures to limit and fix the wire harness.

[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] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0022] A wire threading conduit includes a clamping tube 1, with a wire tube 2 threaded to one end of the clamping tube 1. The clamping tube 1 has a clamping hole 11 inside, and a clamping component 12 is provided on the inner wall of the clamping hole 11. The wire tube 2 has a wire hole 21 inside, and an annular rubber protrusion 22 is fixedly provided on the edge of the wire hole 21 away from the clamping tube 1. A ball bearing 23 is embedded in the inner wall of the wire hole 21.

[0023] With the above solution, when the wire harness is inserted into the wire hole 21, the annular rubber protrusion 22 not only provides guidance and positioning for the wire harness to enter the hole, but also prevents the wire harness from being scratched by the edge of the hole when it is inserted or pulled out, avoids damage to the outer sheath of the wire harness, and extends the service life of the cable. The setting of the ball 23 reduces the frictional resistance of the inner wall of the wire hole 21, thereby making the wire harness insertion smoother and faster, and at the same time, reducing the risk of friction damage to the wire harness.

[0024] Specifically, the clamping assembly 12 includes a mounting groove 121, a U-shaped fixing block 122 is fixedly provided on the inner wall of the mounting groove 121, a clamping rod 123 is hinged to the U-shaped fixing block 122, a rubber anti-slip layer 124 is fixedly provided on the surface of the clamping rod 123 away from the U-shaped fixing block 122, and a return spring 125 is connected between the side of the clamping rod 123 near the U-shaped fixing block 122 and the inner wall of the mounting groove 121.

[0025] With the above solution: when the wire harness enters the clamping hole 11, the squeezing force generated on the clamping rod 123 causes the return spring 125 to contract. When the wire harness moves in the opposite direction to the wire threading direction, the return spring 125 drives the clamping rod 123 to have a certain clamping force on the surface of the wire harness. Furthermore, the surface of the clamping rod 123 is provided with a rubber anti-slip layer 124, which generates a large sliding resistance between the clamping rod 123 and the surface of the wire harness, thereby achieving the automatic clamping effect of the wire harness.

[0026] Specifically, the inner diameter of the wire hole 21 is the same as the inner diameter of the clamping hole 11, the wire hole 21 and the clamping hole 11 correspond one-to-one, and there are five wire holes 21, which are symmetrical about the axis of the wire tube 2.

[0027] Specifically, the outer surfaces of the clamping tube 1 and the wire tube 2 are provided with an annular groove 3, and a fixing component 4 is movably installed inside the annular groove 3. The fixing component 4 includes an annular retaining ring 41, and a mounting base 42 is fixedly provided on the outer side of the annular retaining ring 41. The mounting base 42 is provided with a mounting through hole 43.

[0028] The above solution involves rotating the annular retaining ring 41 to make the mounting base 42 fit against the wall or ground, thus securing the conduit.

[0029] Specifically, a first indicator arrow 5 is fixedly provided on the outer surface of the clamping tube 1 near the end of the wire tube 2, and a second indicator arrow 6 is fixedly provided on the outer surface of the wire tube 2 near the end of the clamping tube 1. The center lines of the first indicator arrow 5 and the second indicator arrow 6 are parallel to the central axes of the clamping tube 1 and the wire tube 2.

[0030] The above scheme provides installation guidance for workers by setting the first indicator arrow 5 and the second indicator arrow 6. When the first indicator arrow 5 and the second indicator arrow 6 are aligned, the wire hole 21 and the clamping hole 11 are also aligned with each other, thereby improving ease of use.

[0031] In this embodiment, the easy-threading conduit is first used by threading the clamping tube 1 and the wire tube 2 together, aligning the arrowheads of the first indicator arrow 5 and the second indicator arrow 6. The first indicator arrow 5 and the second indicator arrow 6 are mainly designed to guide the installation process. When the first indicator arrow 5 and the second indicator arrow 6 are aligned, the wire hole 21 and the clamping hole 11 are also aligned. Then, one end of the wire harness is inserted into the wire hole 21 inside the wire tube 2. The edge of the wire hole 21 away from the clamping tube 1 is provided with an annular rubber protrusion 22, and several balls 23 are embedded in the inner wall of the wire hole 21. The annular rubber protrusion 22 not only provides guidance and positioning for the wire harness when it enters the hole, but also prevents the wire harness from being scratched by the edge of the hole when it is inserted or withdrawn, avoiding damage to the outer sheath of the wire harness and extending the service life of the cable. The balls 23 reduce the frictional resistance of the inner wall of the wire hole 21, making the wire harness threading smoother and faster, and also reducing the risk of friction damage to the wire harness. After the wire harness passes through the wire hole 21, it enters the clamping hole 11 until it exits from the other end of the clamping hole 11. When the wire harness enters the clamping hole 11, the squeezing force exerted on the clamping rod 123 causes the return spring 125 to contract. When the wire harness moves in the opposite direction to the wire insertion, the return spring 125 drives the clamping rod 123 to exert a certain clamping force on the surface of the wire harness. Furthermore, the surface of the clamping rod 123 is provided with a rubber anti-slip layer 124, which generates significant sliding resistance between the clamping rod 123 and the surface of the wire harness, achieving an automatic clamping effect. This prevents the wire harness from slipping out of the slot and eliminates the inconvenience of requiring additional measures to limit and fix the wire harness. Finally, by rotating the annular retaining ring 41, the mounting base 42 is brought into contact with the wall or ground to secure the conduit.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
