Abstract

The invention discloses a shielding cabinet applying a labor-saving technology, which comprises a cabinet body and a cabinet door, wherein the cabinet body is provided with a containing cavity and a cabinet opening, and the cabinet door is hinged on the cabinet body and has a to-be-closed position and a fully-closed position based on rotation of the cabinet door. The cabinet body is provided with an elastic conductive structure at the position surrounding the cabinet opening or at the position corresponding to the periphery of the cabinet opening. The door lock mechanism is arranged on the cabinet door, and the design is exquisite. When the cabinet door is rotated to the position to be closed, the rotation and locking operation of the cabinet door to the fully closed position can be continuously completed only by rotating the operation piece, so that the cabinet door is simple and convenient, and is stable and controllable. On the other hand, the door lock mechanism transmits the reaction force of the elastic conductive structure acting on the cabinet door to the operating member and converts it into a force that hinders the rotation of the operating member. Compared with the method that the front thrust is directly applied to overcome the reaction force of the elastic conductive structure, the rotary resistance is overcome by rotating the operation piece, so that labor is saved, and the force applied by a user for closing the cabinet door is effectively reduced.

Description

Shielding cabinet applying labor-saving technology Technical Field The invention relates to the technical field of electromagnetic shielding, in particular to a shielding cabinet applying a labor-saving technology. Background The mobile phone shielding cabinet is professional equipment for blocking wireless signals by adopting a physical shielding technology, and the core principle is that electromagnetic waves are attenuated and absorbed through a shielding space formed by metal materials, so that a mobile phone in the cabinet cannot establish communication with a base station. In order to reduce the negative influence of the gap between the cabinet door and the cabinet body on the shielding cabinet, the edge of the cabinet opening of the cabinet body or the corresponding position of the cabinet door is generally surrounded by an elastic conductive structure, such as a copper sheet, a conductive sponge strip and the like. When the cabinet door is completely closed, the elastic conductive structure is extruded by the cabinet door and the cabinet body and is in conductive connection with the cabinet door and the cabinet body, so that signals are effectively restrained from entering and exiting the shielding cabinet. Since the elastic conductive structure is compressed, the greater the force that needs to be applied as the compressed portion increases. Therefore, in the closing process of the cabinet door, when the elastic conductive structure starts to be extruded by the cabinet door and the cabinet body, the user can rotate the cabinet door to the fully closed position only by gradually increasing the force applied to the cabinet door along with the rotation of the cabinet door. In this regard, most existing shielding cabinets have magnets mounted on the cabinet body and/or the cabinet door that use magnetic attraction to oppose the reaction force of the elastic conductive structure to reduce the force required to close the cabinet door. However, the structure has two difficult problems that firstly, when the cabinet door is opened, additional force is needed to overcome the magnetic attraction force of the magnet, so that the operation is inconvenient and the user experience is affected. Secondly, be difficult to control dynamics when closing the cabinet door, under the magnetic attraction effect, the cabinet door can accelerate the striking cabinet body suddenly near closed position, produces huge sound and vibrations, brings bad use experience for the user. Thus, improvements are needed in the art described above. Disclosure of Invention The invention aims to provide a shielding cabinet applying a labor-saving technology, which ensures shielding effect, simultaneously enables a cabinet door to be more convenient and labor-saving, and improves user experience. In order to achieve the above purpose, one of the technical schemes adopted by the invention is as follows: The utility model provides an use shielding cabinet of laborsaving technique, its includes the cabinet body and cabinet door, the cabinet body be equipped with hold the chamber and with its cabinet mouth that is linked together, the cabinet door articulated in on the cabinet body, and have to wait closed position and complete closed position based on self rotation. And an elastic conductive structure is arranged on the cabinet body at a position surrounding the cabinet opening or at a position corresponding to the periphery of the cabinet opening. The cabinet door is provided with a door lock mechanism which comprises a lock piece and an operating piece. The locking piece can rotate around a first axis parallel to the plane of the cabinet door and comprises a first swing arm taking the first axis as a swing center. The operating piece is arranged on the front surface of the cabinet door and can rotate around a second axis perpendicular to the plane of the cabinet door. The locking piece is in transmission connection with the operating piece, and the locking piece can rotate along with the rotation of the operating piece. The door lock mechanism thus has an unlocked state and a locked state. The cabinet body comprises a matching part corresponding to the first swing arm, and the matching mode of the door lock mechanism and the matching part is as follows: When the cabinet door rotates to the to-be-closed position, the free end of the first swing arm of the door lock mechanism in the unlocking state is more backward than the matching part, the first swing arm swings from back to front and presses against the matching part in the process of switching the door lock mechanism from the unlocking state to the locking state, the matching part exerts acting force for helping the cabinet door to rotate to the fully-closed position, and the cabinet door reaches the fully-closed position until the door lock mechanism is switched to the locking state, and at the moment, the elastic conductive structure is compressed by the cabinet door and the cabinet body
