Description

Basement hidden door with high stability Technical Field The utility model relates to the technical field of building doors and windows, in particular to a basement hidden door with high stability. Background In the field of building protection facilities, the basement hidden door is used as an important component for guaranteeing the hidden performance and the safety of a basement space, the rationality of the structural design of the basement hidden door directly influences the use effect, on the one hand, the traditional basement hidden door has obvious defects in the aspects of door plate motion control and locking mechanisms, part of hidden doors lack of effective buffering and limiting structures, the door plate is easy to generate larger impact force due to lack of a buffering device in the opening and closing processes, the door plate shakes and even collides with a door frame, noise is generated, the abrasion of the door plate and the door frame is accelerated, the service life of the hidden door is shortened, meanwhile, no reliable limiting measures exist, the door plate can excessively rotate, the hidden door structure is damaged, the normal use and the safety performance of the hidden door are affected, on the other hand, the locking structure of the traditional hidden door is mostly simple bolts or catches are difficult to provide enough resistance capacity, the safety of the basement cannot be effectively guaranteed when the basement is impacted or pried by external force, and therefore the basement hidden door with high stability needs to be redesigned according to the problems. Disclosure of utility model The utility model aims to solve the defects in the prior art, and provides a basement hidden door with high stability. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a basement hidden door with high stability, includes the door frame, door frame diapire fixed mounting has two supporting legs and two backup pads, door frame inside rotation installs the door plant, two backup pad up end all has electronic hydraulic stem through coupling mechanism fixed mounting, door plant inner wall fixed mounting has two fixed plates and two fixed lugs, two electronic hydraulic stem telescopic end has all seted up connecting opening, two the fixed plate respectively with the inside swivelling joint of connecting opening of homonymy, two the equal fixed mounting of backup pad up end has the spring, two spring tip respectively with the fixed lug elastic connection of homonymy, the movable groove has been seted up to the door plant inner wall, the movable groove is inside to be connected with first linking frame through telescopic machanism fixed connection, movable groove inside fixed mounting has the slide bar, the slide bar outer wall has two sliders through the equal fixed mounting of slider inner wall has the second linking frame, first linking frame inside is connected with two second linking inside swivelling joint through linking mechanism, two slider outer wall fixed mounting has the door plant outer wall and the fixed mounting of homonymy with the fixed ear elastic connection of homonymy, door plant inner wall and both sides are all equipped with the fixed mounting of both sides of door plant inner wall.
