Problems solved by technology

However, the steel wire rope is prone to breakage and wear, and there is a safety hazard that the screen door will fall rapidly after the wire rope breaks when the screen door rises or hovers
In addition, when the motor fails or the power is cut off, the screen door in the lifting state cannot be lowered, which affects the follow-up work.

Embodiment Construction

[0021] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on specific embodiments and in conjunction with the accompanying drawings.

[0022] like figure 1 As shown, a lift-type electromagnetic shielded door with a safety self-locking device includes a door frame assembly 1, a door leaf assembly 2, a longitudinal feed mechanism 3, and a lifting mechanism 4. The door frame assembly 1 and the door leaf assembly 2 cooperate with each other to realize the door leaf assembly 2. Locking and opening, the door leaf assembly 2 is installed on the longitudinal feed mechanism 3, and the door leaf assembly 2 is driven by the longitudinal feed mechanism 3 to perform translational movement. The slider assembly 10, on which the longitudinal feed mechanism 3 is mounted, is driven by the slider assembly 10 to lift the longitudinal feed mechanism 3 and the door leaf assembly 2.

Abstract

The invention discloses a lifting-type electromagnetic shielding door with a safe self-locking device. The lifting-type electromagnetic shielding door with the safe self-locking device comprises a doorframe assembly, a door leaf assembly, a longitudinal feed mechanism, and a lifting mechanism; the doorframe assembly is mutually matched with the door leaf assembly to realize the locking and unlocking of the door leaf assembly; the door leaf assembly is installed on the longitudinal feed mechanism and is subjected to a translational movement driven by the longitudinal feed mechanism; the liftingmechanism comprises a stand column assembly and a sliding body assembly capable of sliding up and down relative to the stand column assembly; the longitudinal feed mechanism is installed on the sliding body assembly, and the sliding body assembly drives the longitudinal feed mechanism and the door leaf assembly to perform a lifting movement. The lifting-type electromagnetic shielding door with the safe self-locking device abandons the structure of controlling lifting by steel wire ropes, the lifting mechanism with the coordination of the stand column assembly and the sliding body assembly isadopted, the safe self-locking device is installed on the stand column assembly, and a mechanical lock is formed during power failure to prevent the shielding door from falling.

Description

technical field [0001] The invention relates to a lift-type electromagnetic shielding door with a safety self-locking device, belonging to the technical field of electromagnetic shielding. Background technique [0002] In recent years, with the implementation of mandatory EMC standards for electronic information and electrical industry products, darkroom and simulation technologies have been widely used. The size of the measured object required by this type of system is getting larger and larger, ranging from computers to aerospace vehicles. Therefore, the door required by the shielding project must also be large, and because the inside of the door needs to be pasted with wave-absorbing materials, it is required that the door needs to move more when it is translated. A longitudinal feed movement. In order to meet the above requirements, a guide rail suspension type translation screen door has appeared. However, due to the limitation of plane space, some users cannot achiev...
