Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, and more specifically to electric power fire protection equipment for electric power construction. Background Art

[0002] In the distribution box, in order to avoid the fire inside the distribution box caused by short circuit, an electrical fire-proof current-limiting protector will be installed for circuit protection. Announcement No. CN218351801U proposes a multifunctional electric power construction fire protection device. When there is no wiring work, the wiring port is prone to dust and other tiny debris, which can easily cause blockage of the wiring port. In the subsequent wiring process, poor contact will occur. Through the slide groove, slider, support plate, hinge, baffle, slide rail, pulley, support bar, fixed ring, movable groove and The relationship between the movable rods is that when the electric fire protection equipment is not being wired, the support plate can be pulled first. Under the interaction of the slide groove and the slider, the position of the support plate can be adjusted, and then the position of the baffle can be adjusted. The baffle can be pulled again to make the hinge drive the baffle to rotate, which can facilitate the shielding and protection of the wiring port under the electric fire protector. The support bar is then pulled, and under the interaction of the slide rail and the pulley, the baffle can be supported and fixed to avoid dust and other foreign matter from entering the wiring port, causing poor contact during subsequent wiring.

[0003] The above setting facilitates the installation of the protector in the cabinet by providing a quick-installation mechanism. For distribution cabinets that have a budget for installing the protector in advance, the protector installation position can be given at this time and the installation can be carried out. However, when a cabinet where a protector needs to be installed temporarily does not necessarily have space for the installation of the protector, it is usually installed on the inner wall of the cabinet by bolts. At this time, the quick-installation mechanism cannot be installed, so it cannot be flexibly changed during installation. Utility Model Content
