Technical Field

[0001] The utility model relates to the technical field of cable trays, and particularly relates to a shock-proof cable tray. Background Art

[0002] A cable tray refers to a support component for centrally arranging cables in civil buildings or public buildings. It has various structures and can be divided into trough type, tray type, ladder type, grid type and other structures, and is composed of brackets, cantilever arms and installation accessories. The cable tray in a building can be erected independently or attached to various buildings (structures) and pipe gallery brackets.

[0003] After retrieval, the publication (announcement) number: CN217956594U discloses a heat dissipation device for a reinforced shock-proof cable tray, which relates to the field of cable trays. Aiming at the problem that the existing cable trays cannot provide heat dissipation protection and shock-proof protection for cables during use, resulting in easy damage to the cables during use, the following solution is proposed. It includes a cable tray body and cables. The cable tray body includes an upper cable tray and a lower cable tray, and the upper cable tray and the lower cable tray have the same structure and are symmetrically distributed. The cross-sections of the upper cable tray and the lower cable tray are both arranged in a U shape, and a plurality of upper heat dissipation plates arranged in a linear array and a plurality of lower heat dissipation plates arranged in a linear array are respectively installed in the U-shaped grooves of the upper cable tray and the lower cable tray. The utility model has a novel structure, and the cable tray can provide effective shock-proof protection and heat dissipation protection for the cables, which helps to improve the safety and service life of the cables during use, and can also manage the cables inside the cable tray, which helps to improve the subsequent maintenance efficiency.

[0004] Although the above solution can provide effective shock-proof protection and heat dissipation protection for the cables, when providing shock-proof for the cables, it can only provide shock-proof protection in the vertical direction, and the shock-proof protection effect in the horizontal direction is poor. For this reason, we propose a shock-proof cable tray. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a shock-proof cable tray, by setting a horizontal buffer unit and a shock-proof unit, to solve the problem that when providing shock-proof for the cables, it can only provide shock-proof protection in the vertical direction, and the shock-proof protection effect in the horizontal direction is poor.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A shock-proof cable tray includes a main body unit, and also includes a vertical buffer unit arranged in the main body unit, a horizontal buffer unit arranged outside the main body unit, and a shock-proof unit arranged above the horizontal buffer unit;

[0008] The transverse buffer unit includes a U-shaped seat wrapped around the outside of the main unit, a buffer member arranged in the U-shaped seat, and a connecting arm installed at the end of the buffer member;

[0011] Preferably, the connecting member includes an upper connecting plate installed on the side wall of the upper bridge frame, a lower connecting plate installed on the side wall of the lower bridge frame, and connecting bolts for fastening the upper connecting plate and the lower connecting plate.

[0012] Preferably, the vertical buffer unit comprises a telescopic member arranged on the inner wall of the main unit, a heat sink installed at the telescopic end of the telescopic member, and a rubber gasket installed on the inner side wall of the heat sink.

[0013] Preferably, the telescopic member includes a fixing cylinder installed on the inner wall of the main unit, a buffer spring installed on the inner bottom wall of the fixing cylinder, and a connecting column installed on the end of the buffer spring.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] In the utility model, through the provision of a transverse buffer unit and a shockproof unit, when the wind causes the bridge frame body to move in a transverse impulse, the bridge frame body pushes the movable column to move in the movable through hole through the clamping seat, and compresses the connecting spring, so that the buffer component forms a damping system, which can reduce the transverse vibration of the bridge frame body when the wind blows; and when the connecting seat connected to the building is vibrated, the shockproof spring can slow down the movement of the connecting block in the connecting box, thereby reducing the vibration of the connecting box when the connected building vibrates; the provision of the telescopic component can reduce the vertical vibration of the bridge frame body.
