Abstract

The invention provides a sliding electromagnetic shielding door having low cost, difficult deformation of a door leaf and good sealing property. The shielding door comprises a door frame, a sliding door, an airbag seat, an airbag, an airbag air pressure control device and a suspension bracket component, wherein the top of the sliding door is connected with the suspension bracket component. The shielding door is characterized in that: only one door frame is arranged; the airbag is arranged at the periphery of one side of the door frame facing the sliding door; a horizontal track is arranged on the ground of one side of the door frame facing the sliding door; the airbag is arranged at the bottom of the sliding door; and the bottom of the sliding door in a closed state is hermetically connected with the track through the airbag.

Description

A kind of sliding electromagnetic shielding door

(1) technical field

The present invention relates to electromagnetic shielding chamber the technical field of accessory is installed, be specially a kind of sliding electromagnetic shielding door.

(2) background technology

Existing glide formula electromagnetic shield door, slide slides between two formed gaps of doorframe, and two doorframes all are equipped with air bag towards a side of slide, and its shortcoming is: the cost of making, install two doorframes is high; Two doorframes are prone to cause the door leaf distortion towards the air bag of a side of slide produces power each other to slide effect, influence the sealing of shield door.

(3) summary of the invention

To the problems referred to above, the invention provides a kind of sliding electromagnetic shielding door, its cost is low, door leaf is not yielding, good airproof performance.

Its technical scheme is such: it comprises doorframe, slide, air bag seat, air bag, air bag Pneumatic controller, hanging holder set; Said slide top connects said hanging holder set; It is characterized in that: said doorframe has only one; Said doorframe is equipped with said air bag towards the periphery of a side of slide; Said doorframe is equipped with the track of level on the ground of slide one side, said slide bottom is equipped with said air bag, and the said slide bottom under the closed condition is tightly connected through said air bag and said track;

It is further characterized in that: said track is pre-buried in ground; Said track specifically comprises round steel member, channel-section steel, copper coin; Pre-buried behind the said round steel member of said channel-section steel inner surface spot welding in ground; Said copper coin is anchored in the upper surface of said channel-section steel, the upper surface of said copper coin and surface water plane flush;

Said doorframe is equipped with the doorframe air bag seat towards the periphery of a side of slide, and said slide bottom is equipped with the slide air bag seat, in said doorframe air bag seat, the slide air bag seat said air bag is installed, and said air bag is communicated with said air bag Pneumatic controller;

The opening part of said doorframe air bag seat, slide air bag seat is equipped with the copper sheet elastic contact chip; The corresponding position of the copper sheet elastic contact chip of said slide and said doorframe air bag seat copper coin is installed; Guide rail is equipped with in said slide bottom, and said doorframe and slide the right and left are separately installed with the locking positioning device that cooperatively interacts and install;

The location pulley is loaded on the ground of slide open side of the extended line of said track, and the said slide two bottom sides under the opening is spacing through the biside plate of said location pulley.

After adopting said structure of the present invention, because said doorframe has only one, its cost of making, installing is low; Because said doorframe has only one, said doorframe is equipped with said air bag towards the periphery of a side of slide, and under the said slide closed condition, its horizontal direction only receives the power that the air bag of a side applies, and said slide is not yielding; Because said doorframe is equipped with the track of level on the ground of slide one side, said slide bottom is equipped with said air bag again, and the said slide bottom under the closed condition is tightly connected through said air bag and said track, so its good airproof performance.
