Description

Technical Field

[0001] This utility model relates to the field of swivel fasteners, and more particularly to a swivel fastener used on double uprights. Background Technology

[0002] In construction engineering, the use of a double-upper structure during scaffolding erection is an important technical measure to enhance the overall load-bearing capacity and lateral stability of the scaffolding. The traditional method of connecting double-upper structures is as follows: First, conventional swivel couplers are used to connect two parallel uprights laterally to achieve self-fixation of the double uprights. Then, when installing the horizontal bar, due to the gap between the two uprights, the horizontal bar cannot effectively contact both uprights simultaneously. Therefore, during construction, it is usually necessary to connect the horizontal bar to one of the uprights at a single point using a right-angle coupler.

[0003] However, this connection method requires first connecting the uprights and then separately connecting the horizontal bars, which is cumbersome, inefficient, and the dense use of multiple independent fasteners greatly increases construction time and reduces work efficiency. Furthermore, the core concept of the double-upright design is to enable the two uprights to work together and share the load of the horizontal bars. However, the existing connection method means that the force borne by the horizontal bar can only be transferred to the upright it is connected to. The other upright cannot effectively participate in sharing the load transferred by the horizontal bar, and the force of the horizontal bar cannot be effectively distributed to the double-upright system. This may lead to overload failure of a single upright and its connecting fasteners, posing a certain safety hazard. Utility Model Content

Then, the horizontal locking nut 214 is screwed into the horizontal locking screw 213 to lock and fix the horizontal bar, realizing a stable connection between the two uprights and the horizontal bar. At the same time, it can transfer the force on the horizontal bar to the two uprights, improving stability and safety.

[0015] The vertical mounting assembly 11 further includes a first vertical hinge block 114 and a first vertical hinge rod 115; the first vertical hinge block 114 is located at the left end of the front side of the vertical mounting base 111; the first vertical hinge rod 115 is vertically mounted on the first vertical hinge block 114, with both ends extending upward and downward; the first vertical clamp assembly 12 includes an integrally formed first vertical hinge member 121, a first vertical arc member 122, and a first vertical locking member 123; the first vertical hinge member 121 is hinged to the first vertical hinge rod 115; the left end of the first vertical arc member 122 is connected to the first vertical hinge rod 115, and its arc surface faces the first vertical arc groove 1111; the first vertical locking member 123 is vertically mounted at the right end of the first vertical arc member 122, and its front and rear sides are provided with first vertical locking grooves 1231, which are connected to the vertical locking screw 112. The first vertical arc-shaped member 122 of the first vertical clamp assembly 12 can rotate based on the first vertical hinge rod 115 through the first vertical hinge member 121, thereby opening or closing the first vertical arc-shaped groove 1111. When the first vertical arc-shaped member 122 opens the first vertical arc-shaped groove 1111, one of the two uprights can be placed in the first vertical arc-shaped groove 1111. When the first vertical arc-shaped groove 1111 is closed, the arc surface of the first vertical arc-shaped member 122 and the arc surface of the first vertical arc-shaped groove 1111 lock the upright. At the same time, the first vertical locking groove 1231 is fitted onto the vertical locking screw 112 to lock the upright.

[0016] The vertical mounting assembly 11 further includes a second vertical hinge block 116 and a second vertical hinge rod 117; the second vertical hinge block 116 is located at the right end of the front side of the vertical mounting base 111; the second vertical hinge rod 117 is vertically mounted on the second vertical hinge block 116, with both ends extending upward and downward; the second vertical clamp assembly 13 includes an integrally formed second vertical hinge member 131, a second vertical arc member 132, and a second vertical locking member 133; the second vertical hinge member 131 is hinged to the second vertical hinge rod 117; the right end of the second vertical arc member 132 is connected to the second vertical hinge rod 117, with its arc surface facing the second vertical arc groove 1112; the second vertical locking member 133 is vertically mounted at the left end of the second vertical arc member 132, with second vertical locking grooves 1331 opened on its front and rear sides, and connected to the vertical locking screw 112 through the second vertical locking grooves 1331. The second vertical arc-shaped member 132 of the second vertical clamp assembly 13 can rotate based on the second vertical hinge rod 117 via the second vertical hinge member 131, thereby opening or closing the second vertical arc-shaped groove 1112. When the second vertical arc-shaped member 132 opens the second vertical arc-shaped groove 1112, the other upright of the double uprights can be placed in the second vertical arc-shaped groove 1112. When the second vertical arc-shaped groove 1112 is closed, the arc surface of the second vertical arc-shaped member 132 and the arc surface of the second vertical arc-shaped groove 1112 lock the upright, and at the same time, the second vertical locking groove 1331 is fitted onto the vertical locking screw 112 to lock the upright.

[0017] The second vertical locking member 133 has a locking block 134 on its rear right side. Since the second vertical locking member 133 is located outside the first vertical locking member 123 when locking the two uprights, it is farther from the vertical mounting base 111. This causes a larger opening between the second clamp assembly and the second arc-shaped groove, reducing locking stability. Therefore, by providing the locking block 134, the distance between the second vertical locking member 133 and the vertical mounting base 111 can be reduced, decreasing the opening and improving locking stability.

The horizontal arc-shaped component 222 can rotate based on the horizontal hinge rod 216 via the horizontal hinge component 221, thereby opening or closing the horizontal arc-shaped groove 2121. When the horizontal arc-shaped groove 2121 is opened, the horizontal rod can be locked inside the horizontal arc-shaped groove 2121. When the horizontal arc-shaped groove 2121 is closed, the arc surface of the horizontal arc-shaped component 222 and the horizontal arc-shaped groove 2121 lock the horizontal rod. At the same time, the horizontal locking groove 2231 of the horizontal locking component 223 is fitted onto the horizontal locking screw 213. Finally, the horizontal rod can be locked and fixed by screwing the horizontal locking nut 214 into the horizontal locking screw 213.

[0019] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
