Description

Technical Field

[0001] This utility model relates to the field of power cable technology, and more specifically, to a double-insulated power cable support. Background Technology

[0002] Specialized devices used for fixing, supporting, and protecting power cable systems are widely used in power transmission, rail transit, building facilities, and other fields. Their core function is to provide a stable load-bearing structure for cables, ensuring that cables maintain a reasonable arrangement in overhead, underground, or complex environments, and avoiding the risk of deformation, wear, or short circuits caused by their own weight, external forces, or environmental factors. Cable supports are usually made of metal (such as galvanized steel or aluminum alloy) or composite materials, and have characteristics such as high strength, corrosion resistance, fire resistance, and insulation. Structurally, they are divided into various types such as bracket type, ladder type, and trough type, which can be flexibly selected according to the number of cables, their route, and the installation environment.

[0003] For example, a double-insulated, high-safety, and environmentally friendly power cable with publication (announcement) number CN222867271 U relates to the field of environmentally friendly power cable technology. It includes a tinned copper wire conductor, a filler layer, and an insulation layer body. The insulation layer body is located on the outside of the tinned copper wire conductor, and the insulation layer body is filled with a filler layer. This double-insulated, high-safety, and environmentally friendly power cable features an insulating sleeve that can separate the inner core and effectively support it. It provides good support and tensile strength while offering insulation. The pre-drilled groove on the outside of the insulating sleeve provides space for deformation during insertion. The protective layer works in conjunction with the insulating sleeve to enhance the durability and deformation resistance of the power cable. This double-insulated, high-safety, and environmentally friendly power cable solves the problem that the outer insulation layer of most cables uses a direct sleeve method to protect the internal conductors, resulting in poor compression resistance and inadequate insulation.

[0004] However, based on the working principle proposed in the aforementioned patent, the applicant believes that although the device can enhance the resistance to compression to a certain extent, in actual use, traditional cable brackets are difficult to adjust the height of the cable when it is placed, and the insulation effect is relatively poor, resulting in certain inconveniences and safety issues during use. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides a double-insulated power cable support, which has the advantages of convenient adjustment of cable placement height and better insulation effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a double-layer insulated power cable bracket, including a support screw, a control ring threaded on the surface of the support screw, a connecting plate fixedly installed at the top of the support screw, side support plates fixedly installed on both sides of the top of the connecting plate, a placement groove opened on the inner side of the top of the side support plate, a side support rod movably installed on the inner side of the placement groove, and a support block fixedly installed on the inner side of the side support rod, the support block being made of ceramic material.

[0007] As a preferred embodiment of this utility model, the inner side of the control ring is provided with a connecting thread, and a rotating rod is fixedly installed on the outer side of the control ring.

[0008] As a preferred embodiment of this utility model, a bearing ring is movably connected to the bottom of the control ring, and a tapered ring is fixedly connected to the bottom of the bearing ring.

[0009] As a preferred embodiment of this utility model, a contact ring plate is fixedly installed at the bottom of the conical ring, and a fixing hole is provided on the surface of the contact ring plate.

[0010] As a preferred embodiment of this utility model, the support screw is movably installed in the inner cavity of the conical ring, and a vertical groove is formed on the surface of the support screw.

[0011] As a preferred embodiment of this utility model, a threaded tube is fixedly installed on the outer side of the conical ring, and a control screw is installed on the inner thread of the threaded tube.

[0012] As a preferred embodiment of this utility model, a contact friction rod is fixedly installed at the bottom end of the control screw, and the other end of the contact friction rod is movably installed inside the vertical groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model achieves convenient adjustment of cable placement height through the threaded engagement structure of the support screw and control ring. Combined with the double-layer support system formed by the connecting plate and side support plate, it can stably support cables of different specifications. The placement groove on the inner side of the side support plate, combined with the movable side support rod, allows for flexible adjustment of the cable's lateral position according to actual needs. The specially designed ceramic support block directly contacts the cable surface, effectively improving the overall insulation performance and safety protection level of the bracket, solving the problems of limited adjustment and weak insulation in traditional brackets.

[0015] 2. This utility model achieves single-handed rotation adjustment by controlling the rotating rod on the outside of the control ring. The linkage structure between the bearing ring and the conical ring significantly reduces the frictional resistance during the adjustment process. The fixing holes distributed on the surface of the contact ring plate enhance the connection stability between the bracket and the mounting surface. The vertical groove on the surface of the support screw and the contact friction rod driven by the control screw inside the threaded tube form a multi-point positioning mechanism. After any height adjustment, a self-locking frictional force can be generated to prevent accidental displacement of the bracket when it is under load, ensuring the long-term stability and reliability of the height adjustment system.

Detailed Implementation

[0021] 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.

[0022] like Figures 1 to 4 As shown, this utility model provides a double-layer insulated power cable bracket, including a support screw 1, a control ring 2 threaded on the surface of the support screw 1, a connecting plate 3 fixedly installed at the top of the support screw 1, side support plates 4 fixedly installed on both sides of the top of the connecting plate 3, a placement groove 5 opened on the inner side of the top of the side support plate 4, a side support rod 6 movably installed on the inner side of the placement groove 5, and a support block 7 fixedly installed on the inner side of the side support rod 6. The support block 7 is made of ceramic material.

[0023] The threaded connection between the support screw 1 and the control ring 2 allows for convenient and precise adjustment of the cable bracket height. The double-layer support of the connecting plate 3 and the side support plate 4 provides stable support for cables of different sizes and distributes the stress. The groove 5 inside the side support plate 4 provides a flexible lateral sliding guide space for the side support rod 6. The combination of the side support rod 6 and the support block 7 allows for adjustment of the lateral lifting position according to the cable routing requirements. The ceramic support block 7 enhances the insulation and protection performance of the cable contact surface.

[0024] The control ring 2 has a connecting thread 8 on its inner side and a rotating rod 9 fixedly installed on its outer side.

[0025] By controlling the setting of the outer rotating rod 9 of the control ring 2, the height of the bracket can be adjusted by rotating it with one hand.

[0026] Among them, the bottom of the control ring 2 is movably connected to the bearing ring 10, and the bottom of the bearing ring 10 is fixedly connected to the tapered ring 11.

[0027] By linking the bearing ring 10 with the tapered ring 11, the frictional resistance of the screw rotation during the adjustment process can be reduced.

[0028] The bottom of the conical ring 11 is fixedly mounted with a contact ring plate 12, and the surface of the contact ring plate 12 is provided with a fixing hole 13.

[0029] The connection stability between the bracket and the mounting base can be enhanced by setting the fixing holes 13 on the surface of the contact ring plate 12.

[0030] The support screw 1 is movably installed in the inner cavity of the conical ring 11, and the surface of the support screw 1 is provided with a vertical groove 14.

[0031] By providing the vertical groove 14 on the surface of the support screw 1, a longitudinal positioning trajectory can be provided for the contact friction rod 17.

[0032] Among them, a threaded tube 15 is fixedly installed on the outer side of the tapered ring 11, and a control screw 16 is installed on the inner thread of the threaded tube 15.

[0033] By setting the control screw 16 inside the threaded tube 15, the contact friction rod 17 can be driven to produce lateral displacement.

[0034] The bottom end of the control screw 16 is fixedly installed with a contact friction rod 17, and the other end of the contact friction rod 17 is movably installed inside the vertical groove 14.

[0035] By engaging the friction rod 17 with the vertical groove 14, multi-point self-locking friction can be generated at any height to prevent slippage.

[0036] The working principle and usage process of this utility model are as follows: When using this device, the height adjustment function is achieved through the threaded engagement of the support screw 1 and the control ring 2. Rotating the rotating rod 9 on the outside of the control ring 2 can drive the support screw 1 to rise and fall. At this time, the linkage structure of the bearing ring 10 and the conical ring 11 effectively reduces frictional resistance, making the adjustment process smoother. After the height is determined, the control screw 16 in the threaded tube 15 pushes the contact friction rod 17 to embed into the vertical groove 14 on the surface of the support screw 1, forming a multi-point self-locking friction force to prevent the support from shifting after bearing the load. The lateral position of the cable is adjusted by sliding the side support rod 6 in the placement groove 5 of the side support plate 4. Finally, the cable is fixed by the ceramic support block 7, whose insulation characteristics can block the risk of current leakage. The double-layer structure of the connecting plate 3 and the side support plate 4 disperses the weight of the cable. The fixing hole 13 of the contact ring plate 12 is fastened to the mounting surface by bolts to ensure the stability and safety of the overall structure.
