Description

Technical Field

[0001] The utility model relates to the technical field of industrial buildings, in particular to a scaffolding buckle connector. Background Art

[0002] The disc-lock scaffold is a new type of scaffold, the connection method of the vertical poles with the horizontal poles and diagonal poles is to connect the pins at both ends of the horizontal poles and diagonal poles with the discs of the vertical poles. When installing, just align the plugs of the horizontal poles and diagonal poles with the discs, and then pass the pins through the pin holes on the upper part of the plugs, the disc sockets and the pin holes on the lower part of the plugs in sequence, and then use a hammer to hit the top of the pins, so that the concave arc surfaces on the pin holes of the horizontal poles and diagonal poles are tightly combined with the convex arc surfaces of the pins, and then fix the horizontal poles, diagonal poles and vertical poles.

[0003] When installing the buckle connector, since the outer side of the pin and the inner side of the pin hole are designed to be compatible with each other, before the pin is inserted until the convex arc surface of the pin and the concave arc surface of the pin hole are clamped, the pin and the pin hole are in interference, and the friction is large. It is necessary to repeatedly swing a hammer and continuously hit the top of the pin to fully insert the pin into the pin hole. The construction workers repeatedly swing the hammer, which results in a large workload and low installation efficiency. When disassembling the buckle connector, it is also relatively difficult to knock the pin out of the pin hole from the bottom with a hammer. Utility Model Content

[0005] The technical solution of the utility model to solve the above technical problems is as follows:

[0006] A scaffolding disc buckle connector comprises a disc, a plug and a latch, wherein a plurality of insertion holes are provided on the circumference of the disc, and a first latch hole and a second latch hole are provided on the upper and lower parts of the plug respectively; the latch comprises an outer pin, a pin column and a ball bearing, and the inner sides of the first latch hole and the second latch hole are provided with a first hemispherical limiting groove matched with the ball bearing, the outer pin passes through the first latch hole, the insertion hole and the second latch hole in sequence, the pin column is movably inserted in the vertical groove of the outer pin, and a through hole is correspondingly provided on one side of the vertical groove close to the first hemispherical limiting groove, and a ball bearing is movably arranged in the through hole; a limiting plate whose maximum outer diameter is greater than the maximum inner diameter of the first latch hole is provided on the pin body at the upper part of the outer pin; a pin cap whose maximum outer diameter is greater than the maximum inner diameter of the vertical groove is provided on the top of the pin column, and when the limiting plate abuts against the first latch hole, the through hole is opposite to the first hemispherical limiting groove, and when the pin cap abuts against the outer pin, the bottom of the pin column passes through the outside of the vertical groove.

[0007] The beneficial effects of the utility model are as follows: when installing the disk buckle connector, align the plug of the horizontal rod or the oblique rod with the plug hole on the disk on the column, then insert the outer pin into the first plug hole, the plug hole and the second plug hole in sequence, so that the limit plate and the first plug hole are butted, and then align the pin column with the vertical groove, the pin cap makes the pin column inserted into the vertical groove, the outer edge of the pin cap is butted against the outer pin, the bottom of the pin column extends out of the vertical groove, and when the pin column is inserted into the vertical groove, the ball is squeezed to the right from the through hole, so that the ball column is clamped with the first hemispherical limit groove on the plug, and then the disk and the plug are fixed by the plug; disassembly When removing the disc buckle connector, lift the pin from the bottom of the pin, hold the pin cap, and pull out the pin. At this time, the ball withdraws from the first hemispherical limiting groove due to the loss of pin limit, and then the outer pin is pulled out from the first pin hole, the plug hole, and the second pin hole. The disc buckle connector is provided with a pin, an outer pin and a ball, and the pin and the plug are fixed by clamping the ball with the first hemispherical limiting groove. There is no interference during the insertion and removal of the outer pin and the pin, which is more convenient during installation and removal. There is no need to use a hand hammer to knock repeatedly, which saves the physical strength of the construction workers and makes installation and removal more efficient.
