DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] Example 1

[0018] See also Figure 1 and Figure 2 , which is the first embodiment of the utility model, and this embodiment provides a technical solution: a building scaffolding connection and fastening structure, comprising

[0019] A connecting sleeve 1, a scaffolding tube body 2 inserted into the inner side of the connecting sleeve 1, a bolt 3 penetrating the connecting sleeve 1 and the scaffolding tube body 2 at the same time, and a fastening nut 4 sleeved on the bottom end surface of the bolt 3;

[0020] The anti-slipping insurance structure includes a T-shaped shaft rod 51 welded and fixed on the top surface of the connecting sleeve 1, a rotating base cylinder 52 rotatably sleeved on the surface of the T-shaped shaft rod 51, two anti-slipping blocks 53 welded and fixed on the surface of the rotating base cylinder 52, and a limiting structure arranged between the T-shaped shaft rod 51 and the rotating base cylinder 52. The anti-slipping block 53 fits with the top surface of the bolt 3 and can effectively block and limit the bolt 3. The limiting structure includes an inner groove 54 opened inside one side of the T-shaped shaft rod 51, a spring 55 and a telescopic card bead 56 installed inside the inner groove 54, and a circular card groove 57 opened on the inner wall of the rotating base cylinder 52. The telescopic card bead 56 is movably installed in the inner groove 54 by the spring 55, and the end of the telescopic card bead 56 pops out into the circular card groove 57, which can be used in daily use. When in use, the rotating base cylinder 52 is engaged and limited to ensure that the anti-slip block 53 can be stably located on the top of the bolt 3 for blocking and limiting. Even if the fastening nut 4 is loosened or falls off in the later stage, the bolt 3 will not be displaced in the vertical direction under the blocking of the anti-slip block 53, which plays an anti-slip and insurance role, ensuring the tightness of the connection between the connecting sleeve 1 and the scaffold tube body 2. If the bolt 3 is to be removed in the later stage, it is only necessary to push the anti-slip block 53 with force to make the rotating base cylinder 52 rotate, so that the end of the telescopic card bead 56 is squeezed into the inner groove 54, and the rotating base cylinder 52 can be smoothly rotated, causing the anti-slip block 53 to be rotated and removed from the top of the bolt 3. Without the blocking effect of the anti-slip block 53, the bolt 3 and the fastening nut 4 can be disassembled and assembled normally.

[0021] One end of the spring 55 is fixed to the inner wall of the inner groove 54 , and the other end of the spring 55 is fixed to the telescopic bead 56 to ensure the installation stability of the spring 55 .

[0022] The surfaces of the connecting sleeve 1 and the scaffolding tube body 2 are both penetrated with bolt holes, and the positions of the bolt holes therebetween correspond to each other, so that the bolts 3 can pass through smoothly.

[0023] Example 2

[0024] See also Figures 1 to 3 , which is the second embodiment of the utility model, is based on the previous embodiment, and the difference is that the protective structure can be set to effectively wrap and protect the bottom end threads of the fastening nut 4 and the bolt 3.

[0025] Specifically, it also includes a protective structure, which is arranged at the bottom of the connecting sleeve 1. The protective structure includes a rubber substrate 62 installed on the bottom surface of the connecting sleeve 1, and two rubber protective sleeves 63 arranged on both sides of the rubber substrate 62. The rubber protective sleeve 63 covers the bottom ends of the fastening nut 4 and the bolt 3 on the inside, which can effectively wrap and protect the bottom threads of the fastening nut 4 and the bolt 3, prevent external rainwater from contacting the bottom ends of the fastening nut 4 and the bolt 3, and avoid rusting of the bottom ends of the fastening nut 4 and the bolt 3 due to the infiltration of rainwater, thereby ensuring the normal disassembly and assembly of the subsequent fastening nut 4 and the bolt 3. The protective structure also includes a welding A T-shaped clamping seat 61 fixed at the bottom center of the connecting sleeve 1 and a clamping hole opened at the center of the rubber base plate 62 are connected. The bottom end of the T-shaped clamping seat 61 passes through the clamping hole to the bottom of the rubber base plate 62, so that the rubber base plate 62 and the rubber protective sleeve 63 can be stably limited. If the fastening nut 4 and the bolt 3 are to be removed later, the rubber base plate 62 only needs to be pressed down with force so that the rubber base plate 62 is elastically deformed by the squeezing of the T-shaped clamping seat 61 and is pulled down from the bottom of the T-shaped clamping seat 61. The rubber base plate 62 and the rubber protective sleeve 63 can be directly removed, which is convenient for operators to disassemble and assemble the fastening nut 4 and the bolt 3.

[0026] The rubber substrate 62 and the rubber protective sleeve 63 are an integrated structure, both of which are made of rubber material and will undergo elastic deformation when squeezed.
