They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Example 1

[0021] Please see Figure 1 This utility model provides a technical solution: an installation mechanism for scaffolding in a confined space, comprising: a buckle assembly 1, the buckle assembly 1 including a connecting plate 2 and connecting blocks 3, two connecting blocks 3 respectively fixedly installed on two surfaces of the connecting plate 2, the connecting plate 2 for connecting horizontal bars and vertical bars, the connecting blocks 3 for connecting support rods 101, each connecting block 3 having a cylindrical groove 4 at one end, the cylindrical groove 4 above the connecting plate 2 being opened on the upper surface of the connecting block 3, the cylindrical groove 4 below the connecting plate 2 being opened on the lower surface of the connecting block 3, the support rod 101 being snapped into the cylindrical groove 4, the support rod 101... The upper surface can still be connected to the buckle assembly 1. The buckle assembly 1 has multiple trapezoidal through holes 5. There are four trapezoidal through holes 5, so each pair is set at a right angle. The trapezoidal through holes 5 are used to connect with the connecting rod assembly 7. Each trapezoidal through hole 5 is evenly arranged with the center of the connecting block 3 as the center. There are two first through holes 6 between each pair of adjacent trapezoidal through holes 5. The two first through holes 6 are used to install and connect other connecting rods 8 or other installation elements. The connecting plate 2 is provided with multiple connecting rod assemblies 7. In fact, connecting rod assemblies 7 can be set on all four sides of the connecting plate 2, as needed.

[0022] In actual use, the connecting rod assembly 7 can be connected to the four directions of the connecting plate 2 as needed. Each pair of adjacent directions is separated by a right angle. The upper and lower surfaces of the connecting plate 2 are set by the connecting block 3, which can connect the upper and lower support rods 101. Other through holes on the connecting plate 2 can be used to install stabilizer bars, stabilizer devices, etc.

[0023] Example 2

[0024] Please see Figure 1 - Figure 4 Based on Embodiment 1, the connecting rod assembly 7 includes a connecting rod 8, a telescopic mechanism 10, and a locking block assembly 9. The telescopic mechanism 10 is used to adjust the distance between adjacent parallel connecting rod assemblies 7 to ensure that the floor space of the scaffold can be adjusted within a limited space. One end of each of the two connecting rods 8 is respectively set on the upper surface of the two connecting plates 2. The telescopic mechanism 10 is set in the middle of the other end of the two connecting rods 8. The length of the connecting rods 8 can be adjusted by telescoping the two connecting rods 8, thereby adjusting the length and width of the connecting rods 8. The locking block assembly 9 is set below one end of the connecting rod 8 and is adapted to the trapezoidal through hole 5.

[0025] The locking block assembly 9 includes a fixing block 16 and a toggle block 24. The fixing block 16 is fixedly connected to the lower surface of the connecting rod 8. The fixing block 16 has a larger lower part and a smaller upper part. Each fixing block 16 has a trapezoidal cavity 15 on one side. The toggle block 24 is installed in the trapezoidal cavity 15 and can move up and down under the action of the trapezoidal cavity. The fixing block 16 has a first inclined surface 17 on one side. The setting of the first inclined surface 17 is the key to making the fixing block 16 smaller at the top and larger at the bottom.

[0026] A sliding latch 18 is fixedly connected to the upper surface of the actuating block 24. The sliding latch 18 prevents it from detaching from the connecting rod 8. The sliding latch 18 extends into the trapezoidal cavity 15 and slides therewith. The actuating block 24 is divided into a thin-walled end 19 and a heavy end 20. The thin-walled end 19 is located on the upper side, and the heavy end 20 is located on the lower side. One side of the thin-walled end 19 is set as a first contact surface 21. After the first contact surface 21 is engaged, it will fit against the first inclined surface 17. One side of the heavy end 20 is set with a second contact surface 22. The second contact surface 22 will fit against the first inclined surface 17 during the engagement process. The first contact surface 21 and the second contact surface 22 are smoothly connected. A certain angle is set between the first contact surface 21 and the second contact surface 22. This angle needs to be designed according to the size of the rectangular through hole.

[0027] In actual use, when the connecting rod assembly 7 is snapped onto the connecting plate 2, the heavy end 20 will be pushed up by contacting the upper surface of the connecting plate 2 during the snapping process. Only the fixing block 16 will first extend into the trapezoidal through hole 5. As the fixing block 16 extends in, the space above it becomes smaller. Under the combined action of the trapezoidal cavity 15 and the gravity of the heavy end 20, the heavy end 20 will extend into the trapezoidal through hole 5 along with the first inclined surface 17. Under the action of gravity, it will continue to sink and extend in until the first contact surface 21 and the first inclined surface 17 are completely in contact. Then the locking block assembly 9 will snap into the trapezoidal through hole 5. This process is automatic and does not require manual operation. When it is necessary to remove it, when the connecting rod assembly 7 is lifted up, it will be stuck by the action of the first inclined surface 17 and the heavy end 20. At this time, it is necessary to lift the moving block 24 up by hand first, then lift one end of the connecting rod 8, and then operate the other end in the same way. Finally, the connecting rod assembly 7 can be removed directly.

[0028] Example 3

[0029] Please see Figure 2 Based on Embodiment 2, the telescopic mechanism 10 includes a limiting block 12, a telescopic rod 11, and a screw 14. Each connecting rod 8 has a groove 13 for telescopic sliding. The two ends of each telescopic rod 11 pass through the side walls of the two grooves 13 and are slidably connected to them. The telescopic rod 11 extends evenly into the two connecting rods 8. The two limiting blocks 12 are fixedly connected to the two ends of the telescopic rod 11. The limiting blocks 12 are used to prevent the telescopic rod 11 from separating from the connecting rod 8, and play a certain limiting role. Each limiting block 12 is slidably connected to its corresponding groove 13. The screw 14 is set on the top wall of the groove 13. The rotation of the screw 14 can fix the telescopic rod 11 and the connecting rod 8, so that they will not easily slide after the length is determined. Each screw 14 passes through the top wall of its corresponding groove 13 and is threadedly connected to it.

[0030] In actual use, the connecting rod assembly 7 can be connected to the four directions of the connecting plate 2 as needed, with each pair of adjacent directions differing by a right angle. The upper and lower surfaces of the connecting plate 2 are both set by connecting blocks 3, which can connect the upper and lower support rods 101. When the connecting rod assembly 7 is snapped onto the connecting plate 2, during the snapping process, the heavy end 20 will contact the upper surface of the connecting plate 2 and be lifted up. Only the fixing block 16 will first extend into the trapezoidal through hole 5. As the fixing block 16 extends in, the space above it becomes smaller. Under the combined action of the trapezoidal cavity 15 and the gravity of the heavy end 20, the heavy end 20 will extend into the trapezoidal through hole 5 along with the first inclined surface 17. Under the action, it will continue to sink and extend until the first contact surface 21 and the first inclined surface 17 are completely in contact. Then, the locking block component 9 will be locked into the trapezoidal through hole 5. This process is automatic and does not require manual operation. When it needs to be removed, when the connecting rod component 7 is lifted upward, it will be locked by the action of the first inclined surface 17 and the heavy end 20. At this time, you need to lift the moving block 24 upward by hand first, then lift one end of the connecting rod 8, and then do the same for the other end. Finally, you can directly remove the connecting rod component 7. When it is necessary to adjust the length of the connecting rod component 7, you only need to loosen the screw 14 and then pull the connecting rod 8 to a certain length before tightening the screw 14.
