Description

Technical Field

[0001] This utility model relates to the field of engineering technology such as communication, and in particular to a cable fixing bracket for cable trays in cable ducts. Background Technology

[0002] Cable trays and cable fixing frames are indispensable key components in power, communication and other engineering fields. They are mainly used to securely lay various cables on the cable trays. Their core function is to prevent cables from shifting, shaking or even falling off due to their own weight, vibration, wind and other external forces, thereby ensuring the stable operation of cables in complex environments. At the same time, a reasonable fixing method can also optimize the heat dissipation of cables, extend their service life, and facilitate subsequent maintenance and repair work. They are the basic facilities to ensure the safe and reliable operation of cable network systems.

[0003] Currently, although there are various cable holders on the market, most products have obvious limitations in design and function. One prominent problem is that existing cable holders can usually only fix the cable once. This single-fixation method has many drawbacks. It is difficult to adapt to the dynamic changes of cables in different environments. For example, when cables expand and contract due to temperature changes, single-fixation cable holders cannot provide the corresponding adjustment space, which will lead to uneven stress on the cable and even damage to the cable insulation layer. Utility Model Content

[0004] The technical problem to be solved by this utility model is that existing cable fixing brackets can usually only be fixed once. This single fixing method has many drawbacks. It is difficult to adapt to the dynamic changes of cables in different environments. For example, when cables expand and contract due to temperature changes, the single fixing cable fixing bracket cannot provide the corresponding adjustment space, which will lead to uneven force on the cable and even damage to the cable insulation layer.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a cable tray fixing bracket for cable network, comprising a cable tray body, a first fixing component disposed inside the cable tray body, and a second fixing component disposed on the first fixing component. The first fixing component includes a mounting plate, which is fixedly disposed inside the cable tray body. Placement seats are symmetrically disposed at both ends of the mounting plate, and bidirectional screws are symmetrically disposed in the middle of the mounting plate via bearings. An adjustment seat is threaded onto the upper part of the bidirectional screws. The second fixing component includes a first telescopic rod, which is embedded in the inner walls of the placement seat and the adjustment seat at equal intervals.

[0006] One end of the bidirectional screw extends from the inside of the cable tray body to the outside of the cable tray body and is equipped with an adjusting nut. One end of the adjusting seat is symmetrically equipped with multiple second telescopic rods, and one end of the second telescopic rod is fixedly mounted on the mounting plate.

[0007] Furthermore, a limit rod is fixedly installed at equal intervals at one end of the placement seat, and multiple limit ports are opened at equal intervals on the placement seat. Multiple storage holes are opened inside the limit ports, and a first adjusting spring is installed inside the storage holes.

[0008] Furthermore, a limiting protrusion is provided at one end of the first adjusting spring, and limiting grooves are provided at equal intervals on the limiting rod, with the limiting protrusion and the limiting grooves being compatible.

[0009] Furthermore, a limit plate is provided at the moving end of the first telescopic rod, and a second adjusting spring is provided between the limit plate and the first telescopic rod.

[0010] Furthermore, the inner wall of the limiting plate is embedded with multiple ball bearings, and the limiting plate has multiple mounting slots, with conductive heat dissipation fins installed inside the mounting slots.

[0011] Furthermore, heat dissipation vents are provided at equal intervals on both sides of the cable tray body, and filters are installed inside the heat dissipation vents.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This application, by setting up a first fixing component and a second fixing component, enables flexible fixing of cables at multiple points and in multiple directions. This effectively solves the problems of uneven cable stress and easy damage to the insulation layer caused by the single fixing of existing cable fixing brackets. When the cable expands and contracts due to temperature changes, the first telescopic rod and the second telescopic rod, together with the adjusting seat, the bidirectional screw and the adjusting nut, can realize flexible adjustment of the cable fixing position, providing adjustment space for the dynamic changes of the cable, avoiding the impact on cable performance due to excessive tightness or looseness, and significantly improving the stability and service life of the cable in complex environments.

[0014] 2. By incorporating ball bearings, this application assists in the transport of the cable even when it is not secured, thereby preventing scratches on the cable surface. Furthermore, by incorporating conductive heat sinks and funnel-shaped heat dissipation vents, heat dissipation is achieved for the secured cable, thus better ensuring the cable's performance and lifespan.

[0030] The names of the messages or information exchanged between the multiple devices in this embodiment of the invention are for illustrative purposes only and are not intended to limit the scope of these messages or information. Example 1

[0031] like Figure 1-8 As shown, a cable tray fixing bracket for cable network is disclosed, including a cable tray body 1, a first fixing component 2 is provided inside the cable tray body 1, a second fixing component 3 is provided on the first fixing component 2, and heat dissipation vents 5 with funnel-shaped cross-sections are opened at equal intervals on both sides of the cable tray body 1, and a filter screen 6 is provided inside the heat dissipation vents 5.

[0032] The first fixing component 2 includes a mounting plate 201, which is fixedly installed inside the cable tray body 1. Placement seats 202 are symmetrically arranged at both ends of the mounting plate 201. A bidirectional screw 203 is symmetrically arranged in the middle of the mounting plate 201 via a bearing. An adjusting seat 204 is threaded onto the upper part of the bidirectional screw 203. An adjusting nut 205 is provided at one end of the bidirectional screw 203 extending from the inside of the cable tray body 1 to the outside of the cable tray body 1. Multiple second telescopic rods 206 are symmetrically arranged at one end of the adjusting seat 204. Furthermore, one end of the second telescopic rod 206 is fixedly mounted on the mounting plate 201, and one end of the placement seat 202 is fixedly mounted with limit rods 207 at equal intervals. Multiple limit openings 4 are opened at equal intervals on the placement seat 202, and multiple storage holes are opened inside the limit openings 4. A first adjusting spring 208 is installed inside the storage holes, and a limit protrusion 209 is provided at one end of the first adjusting spring 208. Limit grooves 210 are opened at equal intervals on the limit rods 207, and the limit protrusions 209 and the limit grooves 210 are adapted to each other. Example 2

[0033] like Figure 1-8As shown, this embodiment is obtained by describing the technical features of the second fixing component 3 in detail based on the first embodiment. The remaining technical features are the same as those in the first embodiment, and the similarities will not be repeated here. The difference from the first embodiment is that the second fixing component 3 includes a first telescopic rod 301. The first telescopic rod 301 is embedded in the inner wall of the placement seat 202 and the adjustment seat 204 at equal intervals. The moving end of the first telescopic rod 301 is provided with a limit plate 302. A second adjusting spring 303 is provided between the limit plate 302 and the first telescopic rod 301. A plurality of balls 304 are embedded in the inner wall of the limit plate 302 for assisting in the transmission of the cable. A plurality of mounting slots are opened on the limit plate 302. Conductive heat dissipation fins 305 are provided inside the mounting slots, and the conductive heat dissipation fins 305 are adapted to the limit plate 302. The conductive heat dissipation fins 305 are made of a metal material with good conductivity.

[0034] The overall technical solution formed by the above embodiments is used as follows: When cables need to be laid on the cable tray body 1, the cables to be fixed are threaded through the placement seat 202. Then, by operating the adjusting nut 205, rotating the adjusting nut 205 drives the bidirectional screw 203 to rotate. The rotation of the bidirectional screw 203 causes the adjusting seat 204 to move along the thread direction of the bidirectional screw 203. The movement of the adjusting seat 204, through the extension and retraction of the second telescopic rod 206, finely adjusts the position of the mounting plate 201, thereby adjusting the spacing between the placement seats 202. To accommodate cables of different diameters, the limiting rod 207 is inserted into the limiting port 4, the first adjusting spring 208 is compressed, and the limiting protrusion 209 is engaged in the limiting groove 210, forming a preliminary fixation. At the same time, during the preliminary fixation process, the second telescopic rod 206 extends and retracts in coordination with the first fixing component 2 to adjust the position of the mounting plate 201. The bidirectional screw 203 and the adjusting seat 204 cooperate with the first telescopic rod 301 to make the limiting plate 302 move with the extension and retraction of the cable. The second adjusting spring 303 is compressed or rebounds to provide elastic support for the cable and prevent the fixation from being too tight or too loose, which would affect the performance of the cable.

[0035] The limiting plate 302 has embedded ball bearings 304, which assist in cable transportation and reduce scratches on the cable surface. The heat sink 305 works with the funnel-shaped heat dissipation port 5 to dissipate heat from the fixed cable. The filter screen 6 prevents impurities from entering the cable tray body 1.

[0036] Note that the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the scope of protection of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments.
