Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a scaffold fastener of fast assembly during high altitude construction, including first cardboard 1 and second cardboard 2, the one end of first cardboard 1 is rotated and is connected with second cardboard 2, and the bottom of second cardboard 2 is provided with third cardboard 3 and fourth cardboard 4, and rotate between third cardboard 3 and the fourth cardboard 4 and connect, the bottom intermediate position department of second cardboard 2 rotates through pivot 10 and third cardboard 3 and is connected, the one end of keeping away from the rotation end of second cardboard 2 and fourth cardboard 4 all is provided with two buckles 5, and the orientation of two buckles 5 is opposite, and the vertical end of two buckles 5 is located same water flat line, buckle 5's horizontal end length is less than 11 widths in U-shaped groove.

Specifically, as shown in fig. 1 and 2, first cardboard 1, second cardboard 2, the intermediate position department of third cardboard 3 and fourth cardboard 4 all is to a lateral bend, a connection for the steel pipe, vertical central line symmetry is provided with two joint boards 7 at the top of first cardboard 1, and the longitudinal section of joint board 7 is L shape structure, the interval equals with cardboard thickness between two joint boards 7, the rotation link of first cardboard 1 and second cardboard 2 is pegged graft and is had round pin axle 6, the rotation link of third cardboard 3 and fourth cardboard 4 is pegged graft and is had round pin axle 6.

Specifically, as shown in fig. 1-3, the longitudinal section of two buckles 5 is the J-shaped structure, and the vertical end of two buckles 5 all rotates through torsional spring pivot 8 and second cardboard 2 and fourth cardboard 4 to be connected, and second cardboard 2 and fourth cardboard 4 are kept away from rotation end one end and are all seted up movable groove 9, and the inside of movable groove 9 inlays and is equipped with torsional spring pivot 8, and first cardboard 1 and third cardboard 3 are kept away from rotation end one end and are all seted up U-shaped groove 11.

The working principle is as follows: when the fastener is used, when the fastener is required to be assembled, the first clamping plate 1 is rotated towards one side of the second clamping plate 2 around the pin shaft 6, the first clamping plate 1 pushes the tops of the two buckles 5 away from the U-shaped groove 11 at one side of the pin shaft 6, so that the two buckles 5 rotate towards the inner side, after the two buckles 5 rotate at a proper angle, the top ends of the buckles 5 penetrate out of the top ends of the U-shaped groove 11, the two buckles 5 rotate towards the opposite side under the action of the torsion spring rotating shaft 8, the bottom groove of the buckle 5 limits the position of the first clamping plate 1 to prevent the first clamping plate 1 from turning upwards, as the buckle 5 cannot move in the direction vertical to the pin shaft 6, the buckle 5 cannot tilt towards the outer side, the loss of clamping connection of the first clamping plate 1 is avoided, accidents are prevented, the third clamping plate 3 and the fourth clamping plate 4 at the bottom are clamped by using the same method, and as the aid is not, the fastener is convenient to mount quickly, and the working efficiency is improved; when the fastener is demolishd in needs, press two buckles 5 to the inboard, when the top horizontal position of two buckles 5 is coincided, upwards overturn first cardboard 1, U-shaped groove 11 passes behind buckle 5's the top, continue the upset, 270 backs in the upset, joint board 7 on the first cardboard 1 carries out the joint with the edge of fourth cardboard 4 for the whole shrink of fastener reduces its area occupied, portable and deposit, it is convenient for the installation provides.

The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
