[0029] Embodiment 1:

[0030] refer to Figures 1 to 3 As shown in the figure, a scaffold is shown. The scaffold comprises: square buckles 100 and steel pipes to be fixed.

[0031] Preferably, the square buckle 100 comprises a base 101 and a locking portion 102, wherein each locking portion 102 is fixed on the base 101. Each steel pipe 200 is locked on the base 101 via the locking portion 102.

[0032] Preferably, the base 101 is a cubic structure, the interior of the base 101 is a hollow structure, and the internal space of the base 101 is used to accommodate or pass the steel pipe 200.

[0033] Furthermore, each surface of the base 101 is provided with a locking portion 102. That is, the six side surfaces of the base (101) of the scaffold are provided with locking portions (102).

[0034] Furthermore, the locking portion 102 is arranged at the center of each surface of the base 101, so as to allow a steel pipe (200) to pass through the base (101).

[0035] Preferably, the locking part 102 includes a sleeve 103 and a nut 108. The side wall of the sleeve 103 is provided with a groove 106 along the axial direction, the outer surface of the sleeve 103 is provided with a wedge-shaped threaded part 104, and the nut 108 is sleeved on the sleeve 103 through the threaded part 104; the steel pipe 200 to be fixed is sleeved inside the sleeve 103.

[0036] Because the sleeve 103 is provided with a groove 106, the sleeve 103 has a deformation space. Therefore, by screwing the nut 108, the sleeve contracts inwards under the action of the wedge-shaped threaded portion 104, and the pipe diameter becomes smaller, thereby completing the fastening and locking of the steel pipe 200.

[0037] Preferably, a plurality of protrusion units 105 are provided on the inner wall of the sleeve 103. The protrusion units 105 provide a greater friction force between the sleeve 103 and the steel pipe 200, so that the multiple steel pipes 200 can be better joined.

[0038] Preferably, a limiting retaining ring 107 is further provided at the end of the sleeve 103. The retaining ring 107 can limit the nut 108 from falling off during transportation, thereby improving the installation efficiency of the device.

[0039] Furthermore, a trumpet-shaped groove is provided inside the limit retaining ring 107. That is, the diameter of the mouth at the end of the sleeve 103 is enlarged by the groove, which greatly facilitates the insertion of the steel pipe 200 and improves the installation efficiency of the steel pipe.

[0040] Preferably, the sleeve 103 of the locking portion 102 and the base 101 may be an integrally formed structure. Alternatively, the sleeve 103 of the locking portion 102 and the base 101 may be connected by welding.

[0041] Preferably, the square buckle 100 and the locking portion 102 are steel structures.

[0042] The scaffolding of the present invention is fastened by a wedge-shaped threaded part and a bolt, and a convex unit is arranged on the inner wall of the sleeve to increase the anti-slip force and the gripping force with the steel pipe. A retaining ring is arranged at the end of the sleeve to prevent the nut from falling off, and a flared groove is arranged at the inner mouth of the retaining ring to facilitate the insertion of the steel pipe. After the steel pipe is inserted, it is locked by a hexagonal nut and a wedge-shaped thread to complete the node connection.

[0043] The structural setting of the scaffold makes the construction of the scaffold more convenient, and enhances the connection firmness of the steel pipe, greatly increasing the stability of the scaffold, and realizing the convergence connection of the through nodes of the six faces.

[0044] The above basic examples of the present invention and their further optional examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed for protection by the present invention. In the scheme of the present invention, each optional example can be arbitrarily combined with any other basic examples and optional examples.

[0045] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
