Description

Technical Field

[0001] The utility model relates to the field of cable supporting devices, in particular to an underground special cable provided with a supporting mechanism. Background Art

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer. They are wires that transmit electricity or information from one place to another. Since cables are used to transmit electricity or information, cables in windy environments, such as cables in underground garages, vents, tunnel entrances, etc., need to be installed and fixed with support frames and provide necessary protection measures to prevent the cables from shaking or multiple cables from entangled and rubbed against each other in windy environments, causing wear and cracking of the outer wall of the cables.

[0003] Existing bracket structures generally use multiple bolts, nuts or rivets to fix the protective frame and the mounting wall. The parts used for installation are too many and scattered, which causes workers to frequently bend down to pick up the parts of the bracket when installing the bracket at high places through scaffolding, etc., and they need to calibrate and adjust the position of the parts. As a result, the installation process of the bracket is more cumbersome. A single clamp can neither accommodate the cable nor ensure safe positioning in the double-threaded connector.

[0006] The mounting support assembly includes a plug handle fixedly mounted on one side surface of the U-shaped support plate, the interior of the plug handle is a hollow structure, the top of the upper surface of the plug handle is provided with a through hole, the inner arc surface of the plug handle is movably clamped with a connecting and tightening component, the top of the outer arc surface of the connecting and tightening component is provided with an elastic pressing portion, the elastic pressing portion is movably sleeved with the top of the inner arc surface of the plug handle, and a transition connector is movably sleeved between the bottom of the outer arc surface of the connecting and tightening component and the inner arc surface of the plug handle, the outer arc surface of the transition connector is provided with an external thread, and the outer arc surface of the wire clamp connected by the auxiliary connection will expand the connecting and tightening component again to increase the hollow interior, and the entire supporting structure can not only ensure fixation but also can be quickly installed and accurately positioned by relying on the rotating connection between the sealing stop ring and the positioning tenon ring, and the sealing stop ring and the positioning tenon ring are movably sleeved on the cable, and grooves and protrusions are provided between the two, so that during the connection process, it only needs to align with the connecting part between the two modules to ensure the determination of the cable position.

[0007] Compared with the prior art, the beneficial effects of the utility model are:

[0008] The utility model uses a conical clamping component to expand outward when the cable passes through it in an initial state, and the expansion at this time will squeeze the expansion part at the bottom of the outer arc surface of the connecting and clamping component, so that it presses against the inner arc surface of the base component, further improving the fixing effect in the supporting process. The outer arc surface of the auxiliary connected wire pressing clamp will expand the connecting and clamping component again, increasing the size of its hollow interior. By relying on the rotational connection between the sealing stop ring and the positioning tenon ring, the entire supporting structure can not only ensure fixation, but also can be quickly installed and accurately positioned, avoiding the situation where there are too many parts and the scattered installation process is cumbersome and requires calibration and adjustment of the positions of the parts.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] Example 1

A mounting support assembly 3 is fixedly installed on one side surface of the U-shaped supporting plate 1 through the fastening bolts 2. The mounting support assembly 3 includes a plug handle 301 fixedly installed on one side surface of the U-shaped supporting plate 1. The interior of the plug handle 301 is a hollow structure. A through hole is opened on the top of the upper surface of the plug handle 301. The inner arc surface of the plug handle 301 is movably connected with a connecting and tightening component 302. The connecting and tightening component An elastic pressing portion 303 is provided at the top of the outer arc surface of the component 302, and the elastic pressing portion 303 is movably connected with the top of the inner arc surface of the plug handle 301. A transition connecting piece 304 is movably connected between the bottom of the outer arc surface of the connecting and tightening component 302 and the inner arc surface of the plug handle 301. The outer arc surface of the transition connecting piece 304 is provided with an external thread, and the outer arc surface of the transition connecting piece 304 is movably connected to a base component 305 through the external thread. The inner arc surface of the base component 305 is provided with an internal thread, and the inner arc surface of the base component 305 is movably connected with a conical clamping component 306.

[0018] In this embodiment: wherein, the various components of the plug handle 301 are plugged into each other, and the elastic pressing portion 303 on one side of the pressing and connecting component 302 is pressed to deform under force and installed on the inner arc surface of the plug handle 301. Since the interior of the plug handle 301 is a hollow structure, its expansion space is limited, so the inserted elastic pressing portion 303 is expanded under the restriction of the internal cavity, and the surface is pressed against the inner arc surface of the plug handle 301, and an inner recess is provided in the middle section of the outer arc surface of the connecting and pressing component 302, and the inner recess is formed with the cavity between the plug handle 301, and the transition connector 304 that is movably sleeved on the inner recess is used to assist the rear end of the cable clamping component to achieve a positioning effect.

[0019] Secondly, in order to ensure that the supported cable will not be displaced, a sealing stop ring 308 and a positioning tenon ring 311 are movably sleeved on the cable respectively, and a groove 309 and a protrusion 310 are provided between the two, so that during the connection process, it is only necessary to align the connection part between the two modules to ensure the determination of the cable position.

[0020] Example 2

[0021] See also Figure 4 and Figure 5 , this embodiment further explains Example 1. In the figure, a clamping portion is provided on one side of the outer arc surface of the conical clamping component 306, and a through hole is opened on one side surface of the base component 305. The conical clamping component 306 is adapted to the through hole on one side of the base component 305. A wire pressing clamp 307 is movably sleeved on the outer arc surface of the conical clamping component 306. The outer arc surface of the wire pressing clamp 307 is movably sleeved on the inner arc surface of the base component 305. A compression clamping portion is provided on the inner side wall of the wire pressing clamp 307. A sealing stop ring 308 is movably sleeved on the inner arc surface of the transition connector 304. A groove 309 is provided on one side of the inner arc surface of the sealing stop ring 308. The number of the grooves 309 is two, and they are evenly distributed in the form of an annular array. A protrusion 310 is movably connected to the groove 309 on the inner arc surface of the sealing stop ring 308. A positioning tenon ring 311 is fixedly installed on the lower surface of the protrusion 310. The positioning tenon ring 311 is movably sleeved inside the transition connector 304.

[0022] In the present embodiment: wherein, the expanded portion at the bottom of the outer arc surface of the connecting clamping component 302 is placed in the base component 305, and the movably sleeved conical clamping component 306 in the connected base component 305 is used to support and fix the cable, and a single clamping clamp can neither accommodate the cable nor ensure safe positioning in the double-threaded connector, so the internal wire pressing clamp 307 plays an auxiliary role, because the conical clamping component 306 will expand outward when passing through the cable in the initial state, and the expansion at this time will squeeze the expanded portion at the bottom of the outer arc surface of the connecting clamping component 302, so that it presses against the inner arc surface of the base component 305, further improving the fixing effect during the support process.

[0023] Secondly, the outer arc surface of the auxiliary connecting wire clamp 307 will expand the connecting and tightening component 302 again, thereby increasing the size of its hollow interior. By relying on the rotational connection between the sealing stop ring 308 and the positioning tenon ring 311, the entire supporting structure can not only ensure fixation, but also be quickly and accurately positioned for installation.

[0024] Example 3

[0025] See also Figures 1 to 5 In this embodiment, the various components of the plug handle 301 are plugged into each other, and the elastic pressing part 303 on one side of the pressing and connecting part 302 is pressed to deform under force and installed on the inner arc surface of the plug handle 301. Because the interior of the plug handle 301 is a hollow structure, its expansion space is limited, so the inserted elastic pressing part 303 is expanded under the restriction of the internal cavity, and the surface is pressed against the inner arc surface of the plug handle 301, and the middle section of the outer arc surface of the connecting and pressing part 302 is provided with an inner concave part, and the inner concave part is formed with the cavity between the plug handle 301, and the transition connector 304 that is movably sleeved in the inner concave part is used to assist the rear end to clamp the cable part The parts have a positioning effect, the expanded part at the bottom of the outer arc surface of the connecting and tightening part 302 is placed in the base part 305, and the movably sleeved conical clamping part 306 in the connected base part 305 is used to support and fix the cable. A single clamping clamp can neither accommodate the cable nor ensure safe positioning in the double-threaded connector. Therefore, the internal wire pressing clamp 307 plays an auxiliary effect, because the conical clamping part 306 will expand outward when passing through the cable in the initial state, and the expansion at this time will squeeze the expanded part at the bottom of the outer arc surface of the connecting and tightening part 302, so that it is pressed against the inner arc surface of the base part 305, further improving the fixing effect during the support process.
