Corner connecting structure for shade-shed

Abstract

The invention relates to a corner connecting structure for a shade-shed. The structure comprises leg tubes, beam tubes, leg tube cross joints and oblique connecting tubes. Each leg tube cross joint comprises an insertion body, wherein a hollow pillar is arranged on the upper end face of the insertion body. Stepped surfaces are arranged at the positions of two opposite corners of the upper end face of each leg tube cross joint respectively, wherein grooves are formed in the inner sides of the two stepped surfaces respectively, and the two grooves are perpendicular to each other. A stud is further arranged at the upper end of each stepped surface. A U-shaped fastener is welded to one end of each beam tube, wherein a through hole allowing the corresponding stud to pass through is formed in the bottom of the U-shaped fastener, and one end of the beam tube is buckled in the corresponding groove of the corresponding leg tube cross joint through the U-shaped fastener to enable the corresponding stud to penetrate through the through hole in the bottom of the U-shaped fastener and be fixed through a butterfly nut. The insertion body of each leg tube cross joint is inserted into the upper end of the corresponding leg tube, and a clamping shaft of each oblique connecting tube is inserted in the hollow pillar of the corresponding leg tube cross joint. According to the structure, insertion, buckling and threaded locking are matched to achieve connection, the requirement for high strength is met, and assembly difficulty is not increased.

Description

technical field [0001] The invention relates to a pergola, in particular to a corner connection structure of the pergola. Background technique [0002] At present, pergolas in outdoor products are generally large in size and inconvenient to carry. Although detachable and assembled pergola structures have appeared in recent years, the corner connection strength of this type of pergola is not high, and assembly and disassembly require professional Tools consume a lot of manpower, material resources and time, and are not very convenient to use. The disassembled parts still occupy a large space and are not easy to store. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the object of the present invention is to provide a corner connection structure of a pergola with simple and firm structure, convenient assembly and convenient packing. [0004] In order to achieve the above object, the present invention adopts the following technical...
