Problems solved by technology

In the production process of the telescopic door, the supporting frame of the telescopic door is connected by different profiles. There are many ways to connect, and welding is usually used. This method is not only difficult to control the quality of the welding process, but also has low welding efficiency. Moreover, the welding part is not beautiful. For the bottom frame of the support frame, sometimes the segmented bottom frame must not be welded in sections with other profiles forming the support frame. This undoubtedly increases the processing procedure, increases the processing cost, and reduces the efficiency; The connection method of the support frame directly affects the firmness of the telescopic door as a whole. Since the support frame is generally not made of solid profiles, the frames that are simply welded together have poor compressive and torsional performance.

Abstract

The invention discloses a telescopic door adopting mortises for connection, which comprises support frames, a folding telescopic component and an electric driving device, wherein the folding telescopic component connects a plurality of support frames into a whole body, the support frames comprise bottom frames and edge frames, mortises are arranged on all connecting parts of the edge frames and the bottom frames, the bottom frames are inserted into the mortises of the edge frames and mutually connect different edge frames on the same support frame, and fastening screws are also arranged in the positions of the mortises. The telescopic door in the invention has the advantages of high manufacture efficiency, low manufacture cost and stable and artistic whole body.

Description

technical field [0001] The invention relates to the technical field of building doors and windows, in particular to a retractable door that adopts a mortise and tenon connection. Background technique [0002] At present, the gates of industrial and mining enterprises, government agencies, schools and other units have adopted electric-driven telescopic doors. In the production process of the telescopic door, the supporting frame of the telescopic door is connected by different profiles. There are many ways to connect, and welding is usually used. This method is not only difficult to control the quality of the welding process, but also has low welding efficiency. Moreover, the welding part is not beautiful. For the bottom frame of the support frame, sometimes the segmented bottom frame must not be welded in sections with other profiles forming the support frame. This undoubtedly increases the processing procedure, increases the processing cost, and reduces the efficiency; The...
