Improved bridge device

Abstract

The invention discloses an improved bridge device, which comprises an opening and closing groove arranged on the upper surface of a box body, and a winding and unwinding groove arranged on the right side of the box body and aligned and communicated with the opening and closing groove. An opening and closing plate is arranged in the winding and unwinding groove, and the opening and closing plate iscapable of sliding left and right. The bottom end surface of the opening and closing groove is provided with two electrical connection concave holes arranged equivalently left and right and used forthe access of an electrical contact of electrical equipment. A first sliding groove is arranged inside the box body. The right side of the box body is provided with a third sliding groove communicatedwith the first sliding groove. The top of the third sliding groove is communicated with the left side of the winding and unwinding groove and a second sliding groove is arranged between the third sliding groove and the first sliding groove. The above electrical connection device is simple in overall structure, convenient to use and operate, safe and stable in electrical connection. The occurrenceof electric shock accidents in the real life is greatly reduced, and the life safety of people is effectively guaranteed. Therefore, the device is suitable for popularization and use.

Description

technical field [0001] The invention relates to the field of bridges, in particular to an improved bridge device. Background technique [0002] In order to adapt to the modern high-speed development of the transportation industry, the structure of the bridge has become more and more complex, so it is particularly important for the maintenance of the bridge. The daily maintenance of the bridge requires electrical equipment, and the electrical equipment often needs to be connected temporarily when using electricity. The electrical box of the existing electric box is often directly exposed to the outside, which is easy to enter dust, water, etc., affecting its service life, and the electrical connection concave hole is already charged when the plug is not connected, so It is easy to cause electric shock accidents when plugging in. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved bridge equipment, which c...
