Problems solved by technology

[0002] At present, the pneumatic screen door is used, which has many advantages, but also has the following disadvantages: high manufacturing cost, long production cycle, many fault points, complex structure, unstable performance, and difficult maintenance. In view of these problems, in order to reduce the factors that cause faults, It is an optional technical solution to improve the performance of the door, simplify the production process of the door, shorten the production cycle, reduce the manufacturing cost, and facilitate construction.
However, because the screen door has high requirements on the sealing of the door and the timeliness of locking the door lock, the existing mechanical lock cannot achieve high sealing performance and cannot realize instant locking when entering and exiting

Embodiment 1

[0027] Such as figure 1 As shown, a new type of electromagnetic shielded door includes a door frame 1 and a door leaf 2, which are hinged on one side. The core of the design is a mechanical door lock, which uses an original cam and ratchet combination 8, and is installed on the lock cylinder sheet metal part 6. On the door leaf 2, use the cam concave-convex stroke to control the extension and fall of the push rod 10 (that is, the extension and retraction of the dead bolt 5), so as to realize the closing and opening of the door.

[0028] Such as image 3 As shown, the cam surface of the cam ratchet assembly 8 is in the form of an arrangement of concave and convex intervals, and there is a small groove at the top of the protruding teeth on the cam surface, which is used to fix the push rod bearing 14 that blocks the tail end of the push rod 10 . In order to control the movement angle of the door lock handle 7, a limit piece 12 is set between the door lock handle 7 and the cam r...

Embodiment 2

[0034] Such as figure 1 , 2 As shown, the new electromagnetic shielded door is equipped with a shielding protection device, which is guaranteed to include the shielding strip 9 arranged on the inside of the door frame 1, the shielding sheet metal folding surface 11 on the front side around the door leaf, and the shielding pressure strip 16 on the lower side of the door leaf, and the shielding strip 9 1. The folded surface 11 of the shielding sheet metal part and the shielding bead 16 are made of conductive metal materials (such as copper foil).

[0035] The shielding strip 16 presses the shielding strip 9 as the push rod 10 is pushed out, so that the airtightness between the door frame 1 and the door leaf 2 is better. At the same time, the frame of the door leaf 2 is also provided with a shielding strip shrapnel 17, which is tightly pressed against the shielding strip 9 when the door is closed. Tangentially, the door frame pops up when the door is opened, that is, the shieldi...

Abstract

The invention discloses a novel electromagnetic shielding door, and belongs to the technical field of shielding doors. The novel electromagnetic shielding door comprises a door frame and a door leaf;one side of the door frame is connected to one side of the door leaf through a hinge; a shielding protective device is arranged on the door frame; a mechanical door lock and a pushing rod pressing mechanism connected with the door lock are arranged on the door leaf; a door lock handle is arranged to connect the mechanical door lock; the mechanical door lock is connected with the pushing rod pressing mechanism and controls the pushing rod pressing mechanism; and the pushing rod pressing mechanism resets or respectively generates locking force to the periphery to jack into the door frame. The novel electromagnetic shielding door adopts a purely mechanical door lock, is simple in structure, higher in assembling precision compared with that of a pneumatic door, stable in performance, easy to maintain, short in production period and low in cost, and has certain advantage in the market; shielding pressing strips and shielding strip elastic pieces are in linkage with the overall mechanical structure; effective shielding of the periphery of the door is realized by extruding shielding strips of the door frame; and the operation of the handle is the same as the using method of a common household door lock through fool-proofing measures, which meets the living habits of people, so that human failure is prevented.

Description

technical field [0001] The invention designs a protective door, and more specifically relates to a novel electromagnetic shielding door. Background technique [0002] At present, the pneumatic screen door is used, which has many advantages, but also has the following disadvantages: high manufacturing cost, long production cycle, many fault points, complex structure, unstable performance, and difficult maintenance. In view of these problems, in order to reduce the factors that cause faults, It is an optional technical solution to improve the performance of the door, simplify the production process of the door, shorten the production cycle, reduce the manufacturing cost, facilitate construction, and realize the opening and closing of the screen door by means of a mechanical lock. However, because the screen door has high requirements on the sealing of the door and the timeliness of locking the door lock, the existing mechanical lock cannot achieve high sealing performance and ...
