Description

Technical Field

[0001] This utility model relates to the field of electrical wire accessories technology, specifically to a plug for electrical wire conduit. Background Technology

[0002] Cable conduit, also known as cable sleeve or wire protection pipe, is a conduit system used to protect wires and cables from physical damage and environmental factors. Cable conduit plugs are usually a type of sealing device used at the end of cable conduit to prevent moisture, dust, and other foreign objects from entering the inside of the cable conduit, thus protecting the wires or cables from damage. To ensure the sealing effect of the cable conduit plug, it is equipped with sealing rubber that contacts the inner wall of the cable conduit.

[0003] In the current installation process of electrical conduit plugs, most plugs and sealing rubber are directly inserted into the inner wall of the electrical conduit. If a sealing rubber larger than the inner wall of the electrical conduit is used, although the sealing effect of the plug can be basically guaranteed, the sealing rubber will rub against the inner wall of the electrical conduit during installation, creating resistance and making it inconvenient to install the plug. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a plug for wire conduit, which can overcome the shortcomings of the existing technology in that it is inconvenient to install the plug for wire conduit.

[0005] The technical solution adopted in this utility model is as follows:

[0006] This utility model provides a plug for wire conduit, including a mating cover (200) and a clamping member (300); the mating cover (200) is fitted onto the end of the wire conduit (100); the clamping member (300) is movably installed at the center of the mating cover (200) along the axial direction of the wire conduit (100);

[0007] The clamping member (300) includes a guide post (301), a pressing plate (302), and a rubber ring (303). One end of the guide post (301) is located outside the mating cover (200), and the other end passes through the center of the mating cover (200) and extends into the interior of the wire sleeve (100). The guide post (301) can move along the axial direction of the wire sleeve (100), and the pressing plate (302) is installed at the end that extends into the wire sleeve (100). The rubber ring (303) is sleeved on the outer periphery of the guide post (301) between the pressing plate (302) and the mating cover (200). The rubber ring (303) can seal the wire sleeve (100) under the mutual pressing action of the pressing plate (302) and the mating cover (200).

[0008] Preferably, the rubber ring (303) includes an inner annular wall and an outer annular wall, and an annular cavity (3031) is formed between the inner annular wall and the outer annular wall; the outer diameter of the outer annular wall gradually increases from both ends to the middle, and the cross-section of the annular cavity (3031) is trapezoidal.

[0009] Preferably, an anti-detachment groove (3032) is provided in the middle of the outer wall of the rubber ring (303), and a clamping ring (3033) for abutting against the inner wall of the wire sleeve (100) is installed in the anti-detachment groove (3032).

[0010] Preferably, the extrusion plate (302) and the guide post (301) are detachably connected.

[0015] Preferably, the clamping member (300) further includes a handle (304) fixedly connected at the guide post (301) to the opposite end of the pressing plate (302).

[0016] The plug for wire conduit provided by this utility model has the following advantages:

[0017] First, the rubber ring is placed inside the conduit, and then it is squeezed by the extrusion plate and the matching cover.

Detailed Implementation

[0024] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0025] like Figures 1-4 As shown, this utility model provides a plug for wire conduit, including a mating cover 200 and a clamping member 300; the mating cover 200 is fitted onto the end of the wire conduit 100; the clamping member 300 is movably installed at the center of the mating cover 200 along the axial direction of the wire conduit 100.

[0026] The clamping member 300 includes a guide post 301, a compression plate 302, and a rubber ring 303. One end of the guide post 301 is located outside the mating cover 200, and the other end passes through the center of the mating cover 200 and extends into the interior of the wire sleeve 100. The guide post 301 can move along the axial direction of the wire sleeve 100, and the compression plate 302 is installed at the end that extends into the wire sleeve 100. The rubber ring 303 is sleeved on the outer periphery of the guide post 301 between the compression plate 302 and the mating cover 200. The rubber ring 303 can seal the wire sleeve 100 under the mutual compression action of the compression plate 302 and the mating cover 200.

[0027] With the above structure, the operator inserts the clamping member 300 and the rubber ring 303 into the inner wall of the wire sleeve 100 while simultaneously installing the mating cover 200 on the outer end of the wire sleeve 100. By holding the mating cover 200 and rotating the clamping member 300, the extrusion plate 302 moves towards the mating cover 200 on the inner wall of the wire sleeve 100 via the guide post 301, thereby extruding the rubber ring 303. The rubber ring 303 is limited and extruded by the extrusion plate 302 and the mating cover 200, causing the diameter of the rubber ring 303 to change and expand towards the inner wall of the wire sleeve 100. This allows the rubber ring 303 to fit tightly against the inner wall of the wire sleeve 100. Compared with the prior art, this method first inserts the rubber ring 303 into the inner wall of the wire sleeve 100 and then extrudes it through the extrusion plate 302 and the mating cover 200. The structure is simple, the installation is convenient, and the sealing effect of the device on the wire sleeve 100 is guaranteed.

[0028] At the same time, the friction between the rubber ring 303 and the inner wall of the wire sleeve 100 is increased after the rubber ring 303 is squeezed, which increases the friction between the device and the wire sleeve 100, making the device firmly installed and not easy to fall off.

[0029] Combination Figures 2-4 As shown in the embodiment of this utility model, the rubber ring 303 includes an annular inner wall and an annular outer wall, and an annular cavity 3031 is formed between the annular inner wall and the annular outer wall; the outer diameter of the annular outer wall gradually increases from both ends to the middle, and the cross-section of the annular cavity 3031 is trapezoidal. An anti-detachment groove 3032 is provided in the middle of the outer wall of the rubber ring 303, and a clamping ring 3033 for abutting against the inner wall of the wire sleeve 100 is installed in the anti-detachment groove 3032. The extrusion plate 302 and the guide post 301 are detachably connected.

[0030] With the above structure, the rubber ring 303 has a trapezoidal cross-section. During the extrusion process, the annular cavity 3031 of the rubber ring 303 is squeezed, causing the rubber ring 303 to shrink towards the center, and the diameter of the rubber ring 303 changes, making it fit against the inner wall of the pipe. At the same time, after the rubber ring 303 is squeezed, it will squeeze the clamping ring 3033 in the anti-detachment groove 3032 to contact the inner wall of the wire sleeve 100, further improving the sealing effect of the rubber ring 303. The extrusion plate 302 and the guide post 301 are threadedly connected, and the rubber ring 303 can be quickly assembled by disassembling the extrusion plate 302.

[0031] Combination Figures 2-3 As shown in the embodiment of this utility model, a plurality of friction blocks 201 are provided at equal intervals on the outer wall of the mating cover 200. A plurality of rubber strips 202 are provided on the inner wall of the mating cover 200 to contact the outer wall of the wire sleeve 100.

[0032] With the above structure, when the operator holds and installs the mating cover 200, the surface roughness of the mating cover 200 is increased, reducing the slippage of the mating cover 200 during the installation process; at the same time, when the mating cover 200 is installed at the end of the wire sleeve 100, the rubber strip 202 will contact the end of the wire sleeve 100, increasing the friction between the mating cover 200 and the outer wall of the wire sleeve 100, further reducing the slippage of the mating cover 200 during the installation process.

[0033] Combination Figures 2-4 As shown in the embodiment of this utility model, the mating cover 200 has a contact surface 203 that contacts the end of the wire sleeve 100, and a positioning part 204 that mates with the end of the wire sleeve 100 is provided at the contact surface 203. A threaded hole 205 is provided through the outer wall of the mating cover 200 for the guide post 301 to move threadedly. The clamping member 300 also includes a handle 304 fixedly connected to the guide post 301 at the opposite end of the pressing plate 302.

[0034] With the above structure, when the cover 200 is placed on the end of the wire sleeve 100, the side of the wire sleeve 100 will be inserted into the positioning part 204 to initially position the cover 200, thus facilitating subsequent gripping of the cover 200; when the operator needs to move the extrusion plate 302, the handle 304 is turned and the guide post 301 will drive the extrusion plate 302 through the threaded hole 205, thus facilitating quick adjustment of the position of the extrusion plate 302.

[0035] The plug for wire conduit provided by this utility model has the following features:

[0036] (1) First, the rubber ring is placed inside the inner wall of the wire sleeve, and then it is squeezed by the extrusion plate and the matching cover. The structure is simple and easy to install, ensuring the sealing effect of the device on the wire sleeve. At the same time, the friction between the rubber ring and the inner wall of the wire sleeve is increased after the rubber ring is squeezed, which increases the friction between the device and the wire sleeve, making the device firmly installed and not easy to fall off.

[0037] (2) The rubber ring includes an inner ring wall and an outer ring wall. An annular cavity is formed between the inner ring wall and the outer ring wall. The outer diameter of the outer ring wall gradually increases from both ends to the middle. The cross-section of the annular cavity is trapezoidal.

[0038] In this invention, the annular cavity of the rubber ring is squeezed during the extrusion process, causing the rubber ring to shrink towards the center and the diameter of the rubber ring to change, so that it fits against the inner wall of the pipe.

[0039] Furthermore, an anti-detachment groove is provided in the middle of the outer wall of the rubber ring, and a clamping ring for abutting against the inner wall of the wire conduit is installed in the anti-detachment groove.

[0040] In this invention, after the rubber ring is squeezed, it will compress the anti-detachment groove and the inner wall of the wire sleeve to make contact, thereby further improving the sealing effect of the rubber ring.

[0041] (3) The extrusion plate and the guide column are detachably connected.

[0042] For example, the extrusion plate and the guide post are threaded together, and the rubber ring can be quickly assembled by disassembling the extrusion plate.

[0043] (4) Multiple friction blocks are provided at equal intervals on the outer wall of the cover.

[0044] In this invention, the surface roughness of the mating cover is increased by setting friction blocks, thereby reducing the phenomenon of slippage of the mating cover during installation.

[0045] (5) Multiple rubber strips are provided on the inner wall of the cover to contact the wire conduit.

[0046] In this invention, the rubber strip contacts the end of the wire sleeve, increasing the friction between the mating cover and the outer wall of the wire sleeve, and further reducing slippage during the installation of the mating cover.

[0047] (6) The mating cover has a contact surface that contacts the end of the wire sleeve, and a positioning part that mates with the end of the wire sleeve is provided at the contact surface.

[0048] In this invention, the side of the wire sleeve will be inserted into the positioning part to initially position the mating cover, thereby facilitating the subsequent gripping of the mating cover.

[0049] (7) The outer wall of the cover is provided with a threaded hole for the guide post to move through, and the clamping part also includes a handle fixedly connected to the guide post at the opposite end of the extrusion plate.

[0050] In this invention, rotating the handle causes the guide post to drive the extrusion plate through the threaded hole, thus facilitating quick adjustment of the extrusion plate position.

[0051] Compared with existing technologies, the friction rubber ring is first placed inside the inner wall of the wire conduit, and then squeezed by the extrusion plate and the matching cover. The structure is simple, the installation is convenient, and the sealing effect of the device on the wire conduit is guaranteed. At the same time, the friction between the friction rubber ring and the inner wall of the wire conduit is increased after the friction rubber ring is squeezed, which increases the friction between the device and the wire conduit, making the device firmly installed and not easy to fall off.

[0052] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.

[0053] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
