Technical Field

[0001] The utility model relates to the field of exposed laying of cables, in particular to an adjustable fixing bracket for exposed laying of mineral cables. Background Art

[0002] Mineral cables are a type of fire-resistant cables that provide power transmission to ensure the normal operation of equipment in the fire escape system during a fire, and are widely used in fields such as building construction.

[0003] In building projects, cables are generally laid in the form of cable trays. According to the provisions of Article 3 of 8.7.1, 8.9.1, and 8.9.2 of the "Code for Electrical Design of Civil Buildings" GB51348-2019, mineral insulated cables with a non-combustible outer layer can be laid openly in the electrical shaft. At the same time, the 09D101-6 atlas of mineral insulated cable laying also has corresponding methods for open laying of mineral insulated cables.

[0004] The open laying construction of cables in the electrical shaft has a greater impact on the appearance, and it is necessary to keep the cables straight. However, in actual construction, there will always be deviations when the cables pass through the reserved holes in the floor slabs of the electrical shaft. Moreover, there are axis deviations in each layer of the wall in the electrical shaft, and the traditional cable fixing brackets cannot be adjusted, which results in the need to measure the dimensions of each layer before manufacturing the brackets for fixing the cables, resulting in high installation costs, time-consuming, and laborious problems.

[0005] Based on this, the present application provides an adjustable fixing bracket that can meet the installation requirements of cables in reserved holes with deviations and walls with axis deviations to ensure the straightness of the cables. Summary of the Utility Model

For this purpose, the utility model provides an adjustable fixing bracket for exposed laying of mineral cables, which can meet the installation requirements of cables in reserved holes with deviations and walls with axis deviations to ensure the straightness of the cables.

[0007] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0008] An adjustable fixing bracket for exposed laying of mineral cables is provided, including an installation frame and a cable clamp fixed on the installation frame. The cable clamp includes an upper clamp block, a lower clamp block, and a fastener; the installation frame includes a support leg, an adjustment plate, and a locking nut. Guide sleeves are provided at both ends of the adjustment plate. The support leg is composed of a screw rod and a mounting plate, and its screw rod is movably arranged in the guide sleeve. The bottom of the guide sleeve is provided with an external thread with the same thread as the screw rod. One end of the locking nut is screwed to the external thread of the guide sleeve, and the other end is screwed to the screw rod; the cable clamp is fixedly installed on the adjustment plate.

[0009] In a preferred embodiment of the present utility model, an adjustment groove is provided on the adjustment plate, and the fastener passes through the cable clamp and then passes through the adjustment groove and is screwed with a nut.

[0010] In a preferred embodiment of the present utility model, the fastener includes an internally threaded tube and a screw. The internally threaded tube is embedded in the lower clamp block, and its bottom is exposed from the bottom surface of the lower clamp block. The nut is threadedly connected to the external thread on the exposed end of the internally threaded tube, and the screw is threadedly connected to the internal thread of the internally threaded tube for fixing the upper clamp block on the lower clamp block.

[0011] In a preferred embodiment of the present utility model, the interference fit is provided between the internally threaded tube and the lower clamp block.

[0012] In a preferred embodiment of the present utility model, an annular limiting plate is provided at the top of the internally threaded tube, and the limiting plate is embedded in the lower clamp block.

[0016] 2. The adjustment groove provided on the adjustment plate can adjust the left and right positions of the cable clamp, solving the problem that the hole positions on the cable clamp deviate from the cable due to installation deviation of the fixed bracket and requiring reinstallation of the fixed bracket.

[0017] 3. The designed fastener uses a screw to lock the upper clamping plate on the lower clamping plate, and loosening the nut can move the cable clamp as a whole left and right, that is: the cable can be first clamped in the cable clamp and then the cable clamp can be fixed, and this installation effect is better.
