This structure not only maintains the neat arrangement of cables but also ensures their orderly spatial layout, thereby optimizing cable management and improving cable safety and ease of maintenance.

[0003] With the increasing global awareness of environmental protection, higher requirements have been placed on the environmental performance of cable trays. Composite environmentally friendly cable trays reduce environmental pollution by using environmentally friendly materials and production processes, which is in line with the current trend of green development. Composite environmentally friendly cable trays are made by combining the advantages of metal frames and environmentally friendly materials. Composite environmentally friendly cable trays perform well in corrosive environments and long-span environments.

[0004] When installing composite environmentally friendly cable trays in warehouse corridors, bolts are usually used to secure the installation. However, due to the frequent movement of goods in and out of warehouse corridors, some tall objects will inevitably hit the bottom of the cable trays during movement. Such impacts can easily cause deformation or misalignment of the bottom of the cable trays, which can easily damage the internal cables. Therefore, a composite environmentally friendly cable tray is proposed to address the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a composite environmentally friendly cable tray to solve the problem that when the bottom of the cable tray is hit by an object, it is easy for the bottom of the cable tray to deform or misalign, which in turn can easily damage the internal cables.

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

[0007] A composite environmentally friendly cable tray includes a cable tray shell, a fixing frame on the outer side of the cable tray shell, a protective component fixedly connected to the bottom of the fixing frame, and connecting components fixedly installed at the corners of the cable tray shell.

The protective component includes a support block, a support base fixedly connected to the bottom end of the support block, positioning plates fixedly connected to both sides of the support base, a connecting cavity inside the support base, a shock absorber fixedly connected to the bottom end of the inner wall of the fixing frame, a support plate fixedly connected to the top end of the shock absorber, a connecting column fixedly connected to the top end of the support plate, the outer side of the connecting column fitting against the inner side of the connecting cavity, guide rods fixedly connected to both sides of the bottom end of the support plate, and a positioning bolt threadedly connected to the top of the cable tray shell. The connecting component includes a connecting block, a screw fixedly connected to one end of the connecting block, a movable plate sleeved on the outer side of the screw, a movable groove formed in the middle of the movable plate, and a limit nut threadedly connected to one side of the screw.

[0008] As a further optimization of this utility model, the number of fixing brackets is set to two, and the two fixing brackets are respectively located on both sides of the cable tray housing. The top of each fixing bracket has a corresponding wide slot on both sides, and the top of the fixing bracket is fixedly connected to a fixing seat.

[0009] As a further optimization of this utility model, the number of positioning bolts corresponds one-to-one with the number of wide slots, the positioning bolts are located inside the wide slots, and there is a sliding fit between the positioning bolts and the wide slots.

[0010] As a further optimization of this utility model, the following features are provided: two support blocks are provided, with the two support blocks located on opposite sides of the bottom of the cable tray housing. The positions of the support blocks and the support seats are located on the same central axis. The outer shape of the support seats is arc-shaped. The number of support seats corresponds one-to-one with the number of support blocks. The positioning plate is an inclined structure.

[0011] As a further optimization of this utility model, the position of the support base corresponds vertically to the position of the connecting column, the upper surface of the connecting column is in contact with the inner side of the connecting cavity, and the outer side of the connecting column slides vertically with the bottom of the inner side of the fixing frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, the protective components provide upward movement space for the bottom of the cable tray when it is impacted from the bottom. This helps to mitigate the impact. Even if the cable tray is impacted from one side of the bottom, the positioning bolts will not jam or wear due to gravity imbalance. The cooperation between the positioning plate and the connecting column allows the position of the cable tray to be corrected and automatically restored to its original position, maintaining the correct installation position and avoiding additional stress caused by misalignment. The shock absorber absorbs and mitigates the vibration, thereby reducing damage to the cable tray and internal cables. The connecting components also provide protection for adjacent cable trays, reducing the impact damage to them. Attached Figure Description

[0022] 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.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] Please see Figure 1-5 This utility model provides a technical solution:

[0025] A composite environmentally friendly cable tray includes a cable tray shell 1, a fixing frame 2 on the outer side of the cable tray shell 1, a protective component 3 fixedly connected to the bottom of the fixing frame 2, and connecting components 4 fixedly installed at the corners of the cable tray shell 1. The connecting components 4 protect adjacent cable trays and reduce impact damage. The surface of the cable tray shell 1 is coated with a protective layer 5, which is made of composite epoxy resin material to improve the corrosion resistance of the surface of the cable tray shell 1. The protective component 3 includes two support blocks 31, which are located on both sides of the bottom end of the cable tray shell 1. The positions of the support blocks 31 and the support seats 32 are on the same central axis. The outer side of the support seats 32 is arc-shaped. The number of support seats 32 corresponds one-to-one with the number of support blocks 31. The bottom end of the support block 31 is fixedly connected to the support seat 32. Positioning plates 33 are fixedly connected to both sides of the support seat 32. The positioning plates 33 have an inclined structure. The inside of the support seat 32 is provided with a connecting cavity 34. A shock absorber 35 is fixedly connected to the bottom of the inner wall of the fixed frame 2. Several shock absorbers 35 are arranged equidistantly on the inner wall of the corresponding fixed frame 2. A support plate 36 is fixedly connected to the top of the shock absorber 35. A connecting column 37 is fixedly connected to the top of the support plate 36. The outer side of the connecting column 37 fits against the inner side of the connecting cavity 34. Guide rods 38 are fixedly connected to both sides of the bottom end of the support plate 36. A positioning bolt 39 is threadedly connected to the top of the cable tray housing 1. The connecting assembly 4 includes a connecting block 41. A screw 42 is fixedly connected to one end of the connecting block 41. A movable plate 43 is sleeved on the outer side of the screw 42. A movable groove 44 is opened in the middle of the movable plate 43. A limit nut 45 is threadedly connected to one side of the screw 42. The limit nut 45 is installed on one side of the screw 42. This setting prevents the movable plate 43 from accidentally detaching from the surface of the screw 42. At the same time, the movable plate 43 does not abut against the limit nut 45 and will not hinder the rotation of the movable plate 43.

[0026] As a further implementation of this solution, two fixing brackets 2 are provided. The two fixing brackets 2 are located on both sides of the cable tray housing 1. The top of the fixing bracket 2 has corresponding wide slots 201 on both sides. The inner width of the wide slots 201 is greater than the outer diameter of the positioning bolts 39. The top of the fixing bracket 2 is fixedly connected to a fixing seat 202. This arrangement facilitates the installation and fixing of the fixing bracket 2.

[0027] As a further implementation of this scheme, the number of positioning bolts 39 corresponds one-to-one with the number of wide slots 201. The positioning bolts 39 are located inside the wide slots 201, and there is a sliding fit between the positioning bolts 39 and the wide slots 201. This setting of the wide slots 201 plays a good role in limiting the movement of the positioning bolts 39.

[0028] As a further implementation of this solution, the position of the support base 32 corresponds vertically to the position of the connecting column 37. The upper surface of the connecting column 37 is in contact with the inner side of the connecting cavity 34, and the outer side of the connecting column 37 slides vertically with the bottom of the inner side of the fixing frame 2. In this way, the connecting column 37 supports the connecting cavity 34 without hindering the vertical movement of the connecting column 37 inside the fixing frame 2.

[0029] As a further implementation of this solution, guide holes 203 matching the guide rod 38 are provided on both sides of the bottom end of the inner wall of the fixing frame 2. The surface of the guide rod 38 is slidably connected to the inner side of the guide hole 203, and the bottom end of the guide rod 38 extends to the bottom of the guide hole 203. This provides guidance for the up and down movement of the support plate 36.

[0030] Workflow: The fixing seat 202 at the top of the fixing bracket 2 corresponds to the position of the wall top installation. The cable tray housing 1 is placed between the inner sides of the two fixing brackets 2. The inner side of the fixing bracket 2 provides space for the cable tray housing 1 to move upward when the bottom end is impacted. The fixing bracket 2 is installed by the cooperation of the fixing seat 202 and the bolt and nut. Then, the positioning bolt 39 passes through the wide groove 201 and is threaded to the top of the cable tray housing 1. In the natural state, the positioning bolt 39 is located at the bottom of the wide groove 201. When the cable tray housing 1 is accidentally impacted from the bottom, it can move upward along the wide groove 201 through the positioning bolt 39. Since the inner width of the wide groove 201 is greater than the outer diameter of the positioning bolt 39, this design ensures that even if the cable tray housing 1 is impacted from the bottom side, the positioning bolt 39 will not be jammed or worn due to gravity imbalance.

[0031] In addition, the cable tray housing 1 can move slightly left and right. When the positioning plate 33 first contacts the connecting column 37, the connecting column 37 can slide into the upper connecting cavity 34 along the inclined surface of the positioning plate 33 due to the inclined structure of the positioning plate 33. This corrects the position of the cable tray housing 1 and avoids additional stress caused by misalignment. The impact force generated by the free fall of the cable tray housing 1 can be transmitted to the lower connecting column 37 through the connecting cavity 34, and then transmitted to the shock absorber 35 by the support plate 36 for absorption and mitigation. This can reduce the damage to the inside of the cable tray housing 1 during the fall. The cooperation between the guide rod 38 and the guide hole 203 provides guidance for the movement of the support plate 36.

[0032] To reduce the impact of impacts on adjacent cable trays, screws 42 are installed at the corners of the cable tray housing 1 via connecting blocks 41. During installation, movable plates 43 are fitted onto the screws 42. The other side of the movable plate 43 is fitted onto the screws 42 of the adjacent cable tray via a movable groove 44 in the middle. The distance between the movable plates 43 and the distance between the two corresponding screws 42 is greater than the distance between them, which provides sufficient space for the movement of the screws 42. When the cable tray housing 1 moves upward, the screws 42 at the corners of the adjacent fixed brackets 2 can slide along the inner wall of the movable plate 43, thereby reducing damage and impact on the adjacent cable trays and providing good protection.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
