Description

Threading formula hinge structure for safety cabinet

Technical Field

The utility model relates to a door hinge especially relates to a threading formula hinge structure for safety cabinet.

Background

The door of the safety cabinet needs to be connected with the door frame through a hinge, so that the door can be hinged on the door frame to be opened or closed.

For example, the similar hinge structures are disclosed in the Chinese utility model patent No. ZL96211963.6 (No. CN 2299922Y), the Chinese utility model patent No. ZL02205657.2 (No. CN 2526432Y), the spring door hinge, and the Chinese utility model patent No. ZL03268199.2 (No. CN 2632252Y), the folding door hinge.

The electronic parts in the conventional safety cabinet are generally arranged on a cabinet door, the interior of the cabinet body is also independently supplied with power although lamps are also arranged in the cabinet body, and electrical elements in the cabinet door are not related to the electrical elements in the cabinet body, so that wires do not need to be led into the cabinet body from the interior of the cabinet door. Therefore, the existing hinge for the safety cabinet does not have the threading function.

With the progress of technology, in order to expand the use of the safety cabinet, an intelligent safety cabinet is developed, which may need to associate the control element in the cabinet door with the electronic element in the cabinet body, so that a hinge with a reasonable structure and a wire passing function needs to be developed by a technician.

SUMMERY OF THE UTILITY MODEL
