A junction box for cross transition of multi-row vertical and horizontal electrical bridges

Abstract

The present invention adopts a multi-row vertical and horizontal electrical bridge crossover junction box, including a junction box shell, a bridge fixing seat, a sealing plate and a liner adjustment mechanism, and the front sides of the left surface and the right end surface of the junction box shell are both opened. There are multiple connection holes, and multiple bridge fixing seats are connected to the connection holes provided on the junction box shell. There are four liner adjustment mechanisms, of which two of the liner adjustment mechanisms are arranged on the junction box shell The inner left end surface and the front side of the right end surface, and the other two lining plate adjustment mechanisms are arranged on the upper end surface and the rear end of the lower end surface inside the junction box shell; the present invention has the following beneficial effects: the bridge fixing seat can be adjusted according to the actual size of the bridge frame Adjustment can quickly connect the bridge frame and the junction box shell, and can adjust the liner 2 and liner 3 according to the actual distribution of strong cables and weak cables, so as to facilitate the isolation of strong cables and weak cables.

Description

technical field [0001] The invention belongs to the field of electrical technology, and in particular relates to a junction box for cross transition of multi-row vertical and horizontal electrical bridge frames. Background technique [0002] Due to the needs of intelligent buildings, the large or super-large buildings and buildings that have appeared in recent years have seen an unprecedented increase in the number of cable bridges. System cables such as lighting, power, fire protection, monitoring, television, telephone, broadband, and broadcasting are placed under the beam slab. In the large space, multiple rows of bridges installed vertically and horizontally are used for laying. All cross transitions in the bridge are carried out with bridge connection boxes, which can cancel various elbows. However, the existing connection boxes are used to isolate strong cables and weak cables. It is more troublesome, and the connection to the bridge is more complicated. There is an u...
