Description

Technical Field

[0001] The utility model belongs to the technical field of a supporting device, and more specifically, particularly relates to a supporting device for a fireproof cable tray. Background Art

[0002] A cable tray is a bracket for supporting and laying cables. In the cable tray project in Shanghai by Gequan, cables need to be laid using a cable tray. As a supporting project for the wiring project, there is currently no special specification for guidance, and the specifications and forms of various manufacturers lack universality. Therefore, during the design and selection process, the applicable cable tray should be reasonably selected according to the cable types and quantities of each electrical system.

[0003] Based on the above, the inventor found the following problems: The overall structure of the traditional fireproof cable tray is relatively fixed. When different widths and sizes of fireproof cable trays need to be laid on the supporting device, the traditional supporting device cannot be used in an assembled manner. At the same time, only a single specification of fireproof cable tray can be laid on the traditional fireproof cable tray. When there are more lines to be laid, the adaptability of a single fireproof cable tray is poor.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a supporting device for a fireproof cable tray is provided, in order to achieve the purpose of having more practical value. Summary of the Utility Model

[0005] The purpose and effect of a supporting device for a fireproof cable tray of the utility model are achieved by the following specific technical means:

[0006] A supporting device for a fireproof cable tray includes a mounting base. The mounting base is assembled and installed with the roof through expansion bolts. A threaded rod is installed at the bottom end face of the mounting base through a hinge seat. The threaded rod is threadedly connected with a support frame. A telescopic truss is hingedly installed at the bottom end face of the support frame. A sliding groove is formed in the side wall of the support frame, and a clamping seat is slidably clamped between the sliding grooves. A plurality of telescopic plates are installed between the clamping seats.

[0007] Further, the outer surface of the threaded rod is provided with threads. Threads are provided at the penetration part of the support frame and the threaded rod. The threads provided on the outer wall of the threaded rod are engaged with the threads provided at the penetration part. And a limit block is installed at the end of the threaded rod.

[0008] Further, the telescopic truss is composed of a rectangular frame and an adjusting frame. A chamber is provided inside the adjusting frame. A T-shaped block is installed in the chamber through a limiting groove. And a spring is installed between the T-shaped blocks.

[0009] Further, through holes one are respectively provided on both outer walls of the rectangular frame, and the aperture size of the through holes one is adapted to the diameter size of the T-shaped block.

[0010] Furthermore, a through hole two is provided through the side wall of the support frame, the internal structure of the engaging seat is exactly the same as the internal structure of the telescopic truss, and the engaging seat is snap-fitted and installed between the through holes two through the same structure.

[0011] Furthermore, both the support frame and the telescopic truss are made of metal materials, and galvanized layers are provided on the surfaces of the support frame and the telescopic truss.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By using the through hole one 7 in cooperation with the T-shaped block 1 and the spring, when pressing the T-shaped block, the distance between the telescopic trusses can be adjusted. By changing the distance, fireproof cable trays with different widths can be laid on the telescopic trusses. At the same time, the design of multiple telescopic plates enables multiple layers of fireproof cable trays to be laid on the support device, improving the overall use efficiency of the support device;

[0014] 2. By using the through hole two in cooperation with the engaging seat, different lengths of telescopic plates can be installed between the support frames. Different widths of fireproof cable trays can be erected through the telescopic plates with different lengths, thereby improving the overall assembly effect. BRIEF DESCRIPTION OF THE DRAWINGS
