Concealed deformed stairs of a loft-style building

Abstract

The invention discloses a concealed deformation staircase for a loft-style building, which comprises a loft opening, a fixed shaft is sleeved between the inner walls of the loft opening, the fixed shaft is sleeved with a cover plate, a guide rail is installed on the cover plate, a ladder is clamped on the guide rail, and the ladder is far away from the guide rail A baffle is installed at one end of the baffle, a counterweight is installed on the outer wall of the baffle, a stopper is installed on the top of the attic opening, the top of the stopper is clipped to the baffle, a connecting plate is installed at the end of the cover near the fixed shaft, and a telescopic Scissor-type telescopic chains are installed between the mechanism, the connecting plate and the ladder. When in use, pull down the cover plate, and the cover plate rotates around the fixed shaft, and the telescopic mechanism will extend and push the scissor-type telescopic chain. When the cover is pushed up, the telescopic mechanism will contract and pull the scissor-type telescopic chain, so that the scissor-type telescopic chain will shrink and pull the ladder, and then the ladder will gradually rise into the attic for concealed storage.

Description

Technical field [0001] The present invention relates to the technical field of construction staircase, in particular a hidden staircase of attic building building. Background technique [0002] With the continuous development of the construction industry, the building is more common, and the attic is often used to store some unopened items. People are using the attic to the way to move the ladder and then go to the attic, not only inconvenient, and usually the ladder Placed in the room to occupy the storage space, and some attic will be installed with electric telescopic stairs. This telescopic staircase is hinged by a plurality of connectors to telescopic (such as patented documents CN204940724), but so ladder The overall carrying capacity is low, and the intensity of the cross-hinged link strength is very high, not safe and reliable, and requires the electric control system remote control ladder to telescopide, the cost is high, and we propose a loft building building concealed...

Problems solved by technology

[0002] With the continuous development of the construction industry, attics in buildings are becoming more and more common. The attic is often used to store some items that are not commonly used. When people use the attic, they use the method of moving the ladder and then go to the attic. Putting it in the room takes up storage space, and some attics will install electric telescopic stairs. This kind of telescopic stairs is stretched and retracted by cross-hinging on the side of the pedal through multiple connecting rods (such as patent document CN204940724). However, such a ladder The overall load-carrying capacity is low, and the strength requirements for the connecting rods of the cross hinge are very high, which is not safe and reliable enough, and the electric control system is required to remotely control the expansion and contraction of the ladder, and the cost is relatively high. Therefore, we propose a concealed deformation staircase for attic buildings solve the above problems
