In the present disclosure, the four insertion holes 34 of the disk fastener 30 can be matched with the four connecting members 40 for the scaffold, so that the four crossbars 20 are erected around the upright 10 as a reference line.

The coupling assembly 40 for a scaffold includes a rail connector 41, a locking body 42, and a plug 43.

Fig. 5 is a perspective view of the cross bar connecting head 41 in the present embodiment, fig. 6 is a perspective view of the locking body 42 in the present embodiment, and fig. 7 is a perspective view of the plug pin 43 in the present embodiment.

In the present disclosure, the rail connector 41 is welded to the rail 20, and in other embodiments, the rail connector 41 may be connected to the rail 20 by other means, such as by bolts.

Referring to fig. 3 and 4, the rail connector 41 is inserted into the insertion hole 34 of the disc fastener 30, a cavity 410 is formed inside the rail connector 41, a through hole 411 is formed in the rail connector 41, and the through hole 411 penetrates through the top end and the bottom end of the rail connector 41 and is communicated with the cavity 410.

The locking body 42 is horizontally movably disposed in the chamber 410, the locking body 42 forms a sliding protrusion 420, a locking inclined plane 421 and a locking portion 422, the sliding protrusion 420 protrudes from the locking inclined plane 421, and the locking portion 422 penetrates through the through hole 411 and is used for locking the disc fastener 30.

The latch 43 is vertically movably disposed in the through hole 411, the latch 43 is formed with a first inclined surface 430 and a second inclined surface 431 which are connected to each other, the first inclined surface 430 and the second inclined surface 431 have an angle with the vertical direction, the first inclined surface 430 and the second inclined surface 431 are located on different planes, the first inclined surface 430 is slidably engaged with the sliding protrusion 420, and the second inclined surface 431 is slidably engaged with the locking inclined surface 421.

When the latch 43 moves vertically downward in the through hole 411, the first inclined surface 430 and the second inclined surface 431 push the sliding protrusion 420 and the locking inclined surface 421 respectively, so as to drive the locking body 42 to move in the cavity 410 along the first horizontal direction (in fig. 4, the first horizontal direction is a horizontal leftward direction), so that the locking portion 422 is locked to the disc fastener 30.

When the scaffold is assembled, the cross bar connectors 41 are inserted into the insertion holes 34 of the disc fasteners 30 to realize initial assembly, and then external force is applied to the inserted pins 43 by hammering or other methods, so that the inserted pins 43 move along the through holes 411; the sliding protrusion 420 and the clamping inclined plane 421 are pushed by the first inclined plane 430 and the second inclined plane 431 respectively, so that the clamping body 42 moves in the cavity 410, and finally the clamping portion 422 is clamped to the disc fastener 30, thereby completing the locking between the disc fastener 30 and the vertical rod 10, and further having a stable connection relationship between the cross rod 20 and the vertical rod 10, and solving the problem of potential safety hazard. It should be noted that, if the cross bar connector 41 and the disc fastener 30 need to be detached, the latch 43 is pushed, so that the latch 43 moves reversely, and the pushing force of the first inclined surface 430 and the second inclined surface 431 on the sliding protrusion 420 and the locking inclined surface 421 is cancelled, the locking body 42 has a retractable space, thereby satisfying the condition that the locking portion 422 is released from locking the disc fastener 30, and realizing easy detachment of the connecting assembly 40 for a scaffold from the disc fastener 30. Meanwhile, it should be noted that, because the first inclined surface 430 and the second inclined surface 431 have an included angle with the vertical direction, and the first inclined surface and the second inclined surface are respectively matched with the sliding protrusion 420 and the locking inclined surface 421, the situation that the bolt 43 falls off due to too large hammering force can be avoided.

The guide projection 414 is slidably engaged with the first inclined surface 430. In the implementation process, the top of the bolt 43 is hammered, so that the bolt 43 stably moves downwards in the through hole 411 in the vertical direction due to the guiding support of the guiding convex block 414, and the clamping body 42 is effectively pushed to realize the clamping connection of the disc fastener 30; meanwhile, when an upward pushing force is applied to the bottom of the latch 43, the latch 43 can smoothly and accurately move upward in the through hole 411 due to the guiding support of the guiding protrusion 414, so that the pushing force of the latch 43 on the locking body 42 can be quickly removed.

With reference to fig. 4 and 6, the locking body 42 is formed with a notch 423, the notch 423 deviates from the locking inclined plane 421, the notch 423 has a vertical plane 424 and a top surface located above the vertical plane 424, the locking portion 422 is formed on the vertical plane 424 and is far away from the top surface, the top surface is supported by the bottom wall of the chamber 410, the top surface is in sliding fit with the bottom wall of the chamber 410, and when the locking portion 422 is locked to the disc fastener 30, the vertical plane 424 abuts against the bottom wall of the chamber 410.

Referring to fig. 4, the coupling assembly 40 for scaffolding further includes a first magnetic member 50 and a second magnetic member 52.

The first magnetic material 50 is disposed on the locking body 42, the second magnetic material 52 is disposed in the chamber 410, and a repulsive force is formed between the first magnetic material 50 and the second magnetic material 52 such that the locking body 42 tends to move in the second horizontal direction, and the first horizontal direction is opposite to the second horizontal direction (in fig. 4, the locking body 42 tends to move horizontally to the right due to the repulsive force).

In the implementation process, the first magnetic part 50 and the second magnetic part 52 are arranged between the locking body 42 and the cross bar connector 41, so that the locking body 42 has a tendency of moving towards the second horizontal direction, when the bolt 43 is pushed, and the bolt 43 moves upwards, the repulsive force can quickly enable the locking body 42 to move towards the second horizontal direction, so as to quickly break away from the disc fastener 30, thereby improving the dismounting efficiency of the scaffold, and ensuring the use efficiency of the scaffold.

Referring to fig. 7, the latch 43 is formed with an arc-shaped concave surface 433, and the arc-shaped concave surface 433 is between the first inclined surface 430 and the second inclined surface 431.
