Sleeve-type mortise-and-tenon joint structure unit and application thereof

Abstract

Disclosed is a sleeve-type mortise-and-tenon joint structure unit, comprising: an externally wrapping pipe-type frame (1) and several internally supported pipe-type frames (2) disposed in the externally wrapping pipe-type frame. The externally wrapping pipe-type frame is provided with several openings (3). After some or all of the internally supported pipe-type frames are pulled out of an end part of the externally wrapping pipe-type frame, a vacant part (4) is formed in the externally wrapping pipe-type frame, and the openings and the vacant part form a mortise structure. Further disclosed are two applications of the sleeve-type mortise-and-tenon joint structure unit. The above-mentioned sleeve-type mortise-and-tenon joint structure unit has the advantages of requiring no nail or binder, a stable structure, rapid and convenient assembly and disassembly, durability, lightweightness, reusability, and environmental friendliness.
