Description

Technical Field

[0001] This utility model relates to the field of cable tray technology, specifically a snap-on anti-fall-off cable tray. Background Technology

[0002] Cable trays are classified into various structures such as trough type, tray type, ladder type, and mesh type, and consist of supports, brackets, and installation accessories. Cable trays inside buildings can be installed independently or laid on various building (structure) supports and pipe rack supports. They should be characterized by simple structure, beautiful appearance, flexible configuration, and convenient maintenance. All parts must be galvanized. Cable trays installed outdoors are also permitted.

[0003] In situations with high safety requirements, such as public places or densely populated areas, a cover plate is installed on the top of the bottom channel to prevent cables from being exposed, reduce the possibility of cable damage, and avoid accidents. In addition, the cover plate can also shield electromagnetic interference and ensure the normal operation of the cables. Currently, in order to prevent the cover plate from falling off due to external forces, it needs to be fixed to the bottom channel.

[0004] Currently, torsion spring clips are generally installed on the side plates of the bottom channel to fix the cover plate. However, the applicant found that it is necessary to overcome the elastic force of the torsion spring when disassembling and assembling, which inevitably leads to a high labor intensity when disassembling and assembling one by one. Therefore, we propose a clip-on anti-fall-off cable tray. Utility Model Content

[0005] The purpose of this utility model is to provide a snap-on anti-fall-off cable tray to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a snap-on anti-fall-off cable tray, comprising a bottom groove, wherein a cover plate is hinged to the bottom groove via a hinge;

[0007] U-shaped mounting clips are evenly arranged on the right side of the cover plate;

[0008] The mounting clip is fitted with a U-shaped buckle, the top inner wall of the buckle is in contact with the bottom inner wall of the mounting clip, the buckle is provided with a rotating shaft, the rotating shaft is connected to the support base through a bearing, and the support base is connected to the lifting assembly.

[0009] As a preferred embodiment of the snap-on anti-fall-off cable tray of this utility model, the lifting assembly includes a fixed box, the bottom inner wall of the fixed box is connected to a fixed shaft through a bearing, the top of the fixed shaft is provided with a screw, the outside of the screw is screwed with a fixed rod, and the front and rear sides of the top of the fixed rod are provided with vertical rods penetrating the top of the fixed box, and the top of the vertical rods are connected to a support base.

[0010] As a preferred embodiment of the snap-on anti-fall-off cable tray of this utility model, a driven bevel gear is provided on the fixed shaft, and a driving bevel gear is meshed with the top right side of the driven bevel gear, and the driving bevel gear is provided on the support shaft.

[0011] In a preferred embodiment of the snap-on anti-fall-off cable tray described in this utility model, the support shaft is connected to the right side of the fixing box via a bearing.

[0012] As a preferred embodiment of the snap-on anti-fall-off cable tray described in this utility model, a knob is provided at the right end of the support shaft.

[0013] As a preferred embodiment of the snap-on anti-fall-off cable tray of this utility model, the fixing box has a fixing plate integrally formed on both the front and rear sides.

[0014] As a preferred embodiment of the snap-on anti-fall-off cable tray of this utility model, the fixing plate is provided with screws that connect to the right side of the bottom groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The lifting component moves the support base downward, causing the buckle to press down on the mounting clip, thus fixing the cover plate. When disassembly is required, the lifting component moves the support base upward, causing the buckle to move upward as well. Then, by rotating the buckle through the pivot, the fixing of the mounting clip can be quickly released. Therefore, compared with the torsion spring buckle, it is easier to disassemble and assemble.

[0017] 2. By setting the driven bevel gear, the driving bevel gear and the support shaft, the knob can be rotated on the right side of the bottom groove when adjusting the height of the buckle. Compared with rotating the knob at the bottom of the fixing box, it is more convenient to rotate, and thus easier to disassemble and assemble. Attached Figure Description

[0023] 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.

[0024] As mentioned in the background section, the existing technology of disassembling and assembling torsion spring clips one by one is too laborious. This utility model proposes a clip-on anti-fall-off cable tray. Example 1

[0025] Reference Figures 1 to 4 A snap-on anti-fall-off cable tray includes a bottom groove 1, and a cover plate 2 is hinged to the bottom groove 1 via a hinge.

[0026] U-shaped mounting clips 3 are evenly arranged on the right side of the cover plate 2;

[0027] The mounting clip 3 is fitted with a U-shaped buckle 4. The top inner wall of the buckle 4 contacts the bottom inner wall of the mounting clip 3. The buckle 4 is equipped with a rotating shaft 5, which is connected to the support base 6 through a bearing, allowing the buckle 4 to rotate and thus quickly detach from the mounting clip 3. The support base 6 is connected to the lifting assembly.

[0028] The lifting assembly includes a fixed box 7. The bottom inner wall of the fixed box 7 is connected to a fixed shaft 8 via a bearing. A screw 9 is provided at the top of the fixed shaft 8. A fixed rod 10 is screwed to the outside of the screw 9. Vertical rods 11 are provided on the front and rear sides of the top of the fixed rod 10, penetrating the top of the fixed box 7. The top of each vertical rod 11 is connected to a support seat 6. When the fixed shaft 8 rotates, the screw 9 drives the fixed rod 10 to rise and fall, thereby driving the support seat 6 on the vertical rod 11 to rise and fall.

[0029] To facilitate the rotation of the fixed shaft 8, a driven bevel gear 12 is provided on the fixed shaft 8. The top right side of the driven bevel gear 12 is meshed with a driving bevel gear 13. The driving bevel gear 13 is provided on the support shaft 14. The support shaft 14 is connected to the right side of the fixed box 7 through a bearing. A knob 15 is provided at the right end of the support shaft 14, making it more convenient to rotate the knob 15 on the right side. Example 2

[0030] Reference Figures 1 to 2 The front and rear sides of the fixing box 7 are integrally formed with fixing plates 16. The fixing plates 16 are provided with screws 17 that connect to the right side of the bottom groove 1, which can fix the fixing box 7.

[0031] The rest of the structure is the same as in Example 1.

[0032] Rotating knob 15 causes support shaft 14 and drive bevel gear 13 to rotate, which in turn drives driven bevel gear 12, fixed shaft 8, and screw 9 to rotate. This allows support base 6 to move buckle 4 downward to fix mounting clip 3. When it is necessary to lift cover 2, support base 6 moves buckle 4 upward until it is no longer obstructed by mounting clip 3 during rotation. Then, buckle 4 is rotated to the right via shaft 5 to disengage from mounting clip 3, thus releasing the fixation of cover 2. The entire process only requires rotating knob 15 and buckle 4, without having to exert force to overcome the spring force of torsion springs. Therefore, compared to disassembling and assembling multiple torsion spring buckles, it is much less strenuous to disassemble and assemble multiple buckles 4.

[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.
