Concealed deformed stairs of loft-style building

Abstract

The invention discloses concealed deformed stairs of a loft-style building. The stairs include a loft entrance. A fixing shaft is sleeved in the inner walls of the loft entrance. The fixing shaft is connected to a cover plate in a sleeving manner. Guide rails are mounted on the cover plate. A ladder is clamped to the guide rails. A baffle plate is mounted on one end, being away from the guide rails, of the ladder. A counterweight is mounted on the outer wall of the baffle plate. A block is mounted on the top of the loft entrance. The top of the block is clamped to the baffle plate. A connecting plate is mounted on one end, being close to the fixing shaft, of the cover plate. A telescopic mechanism is mounted between the connecting plate and the fixing shaft. A scissor type telescopic chainis mounted between the connecting plate and the ladder. When the concealed deformed stairs are in use, the cover plate is pulled down, the cover plate rotates around the fixing shaft, the telescopicmechanism is linked to extend and pushes the scissor type telescopic chain, the scissor type telescopic chain extends and pushes the ladder, and the ladder gradually slides down through the guide rails and presses on the floor of a house. When the concealed deformed stairs are not in use, the cover plate is pushed up, the telescopic mechanism communicatedly contracts to pull the scissor type telescopic chain, and so the scissor type telescopic chain contracts and pulls the ladder and the ladder gradually rises into a loft, thereby storing the ladder in a concealed way.

Description

technical field [0001] The invention relates to the technical field of building stairs, in particular to a concealed deformed staircase for a loft-style building. Background technique [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 bearing capacity is low, and the strength requirements for the cross-hinged connecting rods are very high, which is not safe and reliable enough, and requires an electric control system to remotely cont...

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
