Square tube buckle

Abstract

The invention belongs to the technical field of aluminum formwork system accessories, and discloses a square tube buckle. The square tube buckle comprises a main seat, a pin assembly and an insertingpiece. The main seat comprises a seat stand plate in a rectangular shape as a whole, a first seat flat-plate and a second seat flat-plate, wherein the first seat flat-plate and the second seat flat-plate are arranged on two opposite side faces of the seat stand plate respectively. The seat stand plate is provided with a pin hole penetrating through the seat stand plate, and the pin assembly is inserted into the pin hole. A first inserting piece hole is formed in the end, away from the pin assembly, of the first seat flat-plate in a penetrating mode. A second inserting piece hole penetrating through the second seat flat-plate is formed in the position, facing the first inserting piece hole, of the second seat flat-plate. The inserting piece penetrate through the first inserting piece hole and the second inserting piece hole at the same time. A pin piece comprises a supporting plate and a clamping plate connected with each other. Compared with correlated technologies, the main seat of the square tube buckle is provided with an avoiding notch, and thus the square tube buckle can adapt to aluminum formworks with different edge rib structures, meanwhile, the moving track of the inserting piece is changed, so that the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of welding equipment, and specifically discloses a square button. Background technique [0002] In the pull-tab system of the aluminum formwork, the wall formwork needs to be kept flat by means of a square pass, and the square pass buckle is used to connect and fix the square pass to the wall formwork. In the related art, Chinese patent application number 201610281936.5 discloses a square button, including: a main board; The upper part of the hole is provided with a pin cover, and the pin cover is fixedly connected with the pin plate; the upper right part of the main body plate extends upwards with a connecting nail plate, and the connecting nail plate is fixed with connecting nails; the right side of the pin plate is connected with the left side of the connecting nail plate and The upper side of the main board together forms a square through groove; the lower side of the main board is provided with a protr...

Problems solved by technology

The disadvantage of the related technology is that the through buckle in the related art can only be used on the aluminum formwork with flat side ribs. When connecting the aluminum formwork with the back hook structure, the square through buckle cannot be connected and needs to be polished; and in the related art The movement trajectory of the insert piece when locking and loosening is a curved surface, which is easy to wear, and it cannot be used after wear, and the service life is short
