Shielding electric fan-shaped door

Abstract

The invention discloses a shielding electric fan-shaped door. The shielding electric fan-shaped door comprises a door frame and a door body, wherein the right side of the door body is hinged to the door frame, the left side of the door body is rotationally connected with a rotating shaft, and the two ends of the rotating shaft extend out of the door body and are connected with an outer handle and an inner handle correspondingly. According to the shielding electric fan-shaped door, a spur gear and double spur racks are adopted for reciprocating linear conduction, a needle bearing and a linear bearing which are high in machining precision and stable in performance are matched for guiding, mechanical friction is reduced, hard contact is reduced, all the adopted mechanisms are externally installed, when power is suddenly cut or a motor breaks down, the shielding door can be directly opened through manual operation after an emergency stop button is pressed down, the safety of a user is guaranteed, the structure that a conical knife and a L-shaped knife are matched with a beryllium copper reed is adopted, the conical knife can solve the precision problem in the production and machining process, the L-shaped knife plays a re-shielding effect, errors generated in the production and machining process can be compensated through the conical knife inserting structure on the door, the production and machining errors are reduced, and therefore the shielding performance is stable and superior.

Description

technical field [0001] The invention relates to the technical field of shielding doors for shielding rooms, in particular to a shielding electric fan-shaped door. Background technique [0002] The main function of the shielding room is to isolate the electromagnetic interference from the outside world and ensure the normal operation of indoor electronic and electrical equipment. Especially in the measurement and testing of electronic components and electrical equipment, using an electromagnetic shielding room or darkroom to simulate an ideal electromagnetic environment can improve The accuracy of the test results. The shielding room blocks the diffusion of electromagnetic radiation in the room to the outside. The source of strong electromagnetic radiation should be shielded and isolated to prevent interference with the normal operation of other electronic and electrical equipment and even damage the health of the staff. The shielding room can also prevent electronic communica...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing shielding doors for shielding rooms have a single structure, which is prone to structural instability after long-term use, and most of the existing shielding doors have mechanical structures installed inside the door body, resulting in mechanical or motor failures. The shielding door needs to be demolished to be repaired and it is not convenient to open the shielding door by manual operation. The safety is low. In addition, the shielding performance of the existing shielding door is also unstable, which has a certain impact on the normal use of the shielding room. Therefore, The invention proposes a shielded electric fan-shaped door to solve the problems existing in the prior art
