Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, specifically to a scaffolding connection mechanism. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It can be classified according to its location as external scaffolding or internal scaffolding; according to its material as wooden scaffolding, bamboo scaffolding, or steel pipe scaffolding; and according to its structural form as pole-type scaffolding, bridge-type scaffolding, frame-type scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, or climbing scaffolding.

[0003] Traditional scaffolding connection methods, such as coupler connections, lack durability and long-term stability. They are prone to wear and loosening during use, increasing maintenance workload and affecting the overall safety of the scaffolding. Therefore, a new scaffolding connection mechanism is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a scaffolding connection mechanism to solve the problems existing in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scaffolding connection mechanism, comprising a scaffolding body and an upper fixing ring slidably connected to the surface of the upright of the scaffolding body, and further comprising:

[0006] A plurality of connecting posts are fixedly connected to the top of the upper fixing ring, and a connecting sleeve is fixedly connected to the top of the connecting posts;

[0007] The fixing components used to connect the scaffold body are located inside the connecting sleeve.

[0008] Preferably, the fixing component includes a base ring fixedly connected to the bottom of the inner cavity of the connecting sleeve, a plurality of arc-shaped plates fixedly connected to the top of the base ring, an arc-shaped block fixedly connected to the top of the arc-shaped plates, a clamping sleeve movably connected to the surface of the arc-shaped block, an external thread provided on the surface of the clamping sleeve, a threaded groove provided above the inner cavity of the connecting sleeve, the external thread cooperating with the threaded groove, and a handwheel ring fixedly connected to the top of the clamping sleeve.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4As shown, a scaffolding connection mechanism includes a scaffolding body 1 and an upper fixing ring 2 slidably connected to the surface of the upright of the scaffolding body 1. A lower fixing ring 8 is slidably connected to the surface of the upright of the scaffolding body 1. The top of the lower fixing ring 8 has several threaded holes 9. The surface of the upper fixing ring 2 is provided with several fixing bolts 10 that cooperate with the threaded holes 9. Both the upper fixing ring 2 and the lower fixing ring 8 have connecting grooves 11, which fit against the crossbars of the scaffolding body 1. The connecting grooves 11 ensure that the fixing rings are in close contact with the uprights of the scaffolding body 1, reducing gaps and preventing the fixing rings from wobbling on the uprights of the scaffolding body 1, thereby enhancing the overall stability of the connection. With this configuration, once the upper fixing ring is adjusted... After the upper fixed ring 2 and the lower fixed ring 8 are positioned, the operator can tighten the fixing bolt 10 so that it screws into the threaded hole 9, thereby locking the upper fixed ring 2 and the lower fixed ring 8 onto the upright of the scaffold body 1, thus achieving position fixation. Several connecting posts 3 are fixedly connected to the top of the fixed ring 2, and connecting sleeves 4 are fixedly connected to the top of the connecting posts 3. The connecting sleeve 4 is provided with a fixing component 5 for connecting the scaffold body 1. The fixing component 5 includes a base ring 51 fixedly connected to the bottom of the inner cavity of the connecting sleeve 4. Several arc-shaped plates 52 are fixedly connected to the top of the base ring 51, and arc-shaped blocks 53 are fixedly connected to the top of the arc-shaped plates 52. Several anti-slip protrusions 7 are provided inside the arc-shaped blocks 53, and they are evenly distributed.

[0022] The anti-slip ridges 7 increase the friction between the arc-shaped block 53 and the connected upright, preventing slippage due to vibration or force after connection and improving clamping stability and safety. A clamping sleeve 55 is movably connected to the surface of the arc-shaped block 53. An arc-shaped groove 6 is provided at the bottom of the inner cavity of the clamping sleeve 55, and the inner wall of the arc-shaped groove 6 fits against the surface of the arc-shaped block 53. The arc-shaped groove 6 provides space for the arc-shaped block 53 to contract or expand, while ensuring that the clamping sleeve 55 can stably contract or expand the arc-shaped block 53 during rotation. The surface of the clamping sleeve 55 is provided with external threads 56, and a [missing information - likely a thread type] is provided above the inner cavity of the connecting sleeve 4. The threaded groove 54 and the external thread 56 are used in conjunction with the threaded groove 54. The top of the clamping sleeve 55 is fixedly connected to the handwheel ring 57. Through the setting of the fixing component 5, when the operator connects multiple scaffold bodies 1, first slide the connecting sleeve 4 to the surface of the upright of the scaffold body 1 to be connected, and then rotate the handwheel ring 57. The handwheel ring 57 drives the clamping sleeve 55 to rotate. Through the transmission of the external thread 56 and the threaded groove 54, the rotational motion is converted into axial motion, so that the clamping sleeve 55 presses the surface of the arc block 53. The arc block 53 drives the arc plate 52 to contract inward, thereby gripping the upright of the scaffold body 1 to be connected.

[0023] Working principle: First, slide the upper fixing ring 2 to the upright where the horizontal bar needs to be connected. At this time, the upper fixing ring 2 is in contact with the steel frame of the scaffold body 1. Then, put the lower fixing ring 8 on the same steel frame and adjust it to the relative position with the upper fixing ring 2. After the positions of the upper fixing ring 2 and the lower fixing ring 8 are adjusted, tighten the fixing bolt 10 on the surface of the upper fixing ring 2 so that it passes through the upper fixing ring 2 and is screwed into the threaded hole 9 of the lower fixing ring 8, locking the two on the steel frame to prevent slippage. Then, insert the upright of the other scaffold component to be connected into the inside of the connecting sleeve 4 so that it contacts the arc plate 52 on the base ring 51. Then rotate the handwheel ring 57. Rotating the movable clamping sleeve 55 clockwise causes it to move downward along the threaded groove 54. The arc-shaped groove 6 at its bottom presses against the arc-shaped block 53, which contracts inward under the constraint of the arc-shaped groove 6. Simultaneously, the arc-shaped plate 52 clamps the upright, thus completing the installation. When the worker needs to dismantle, the handwheel ring 57 can be rotated counterclockwise to move the clamping sleeve 55 upward along the threaded groove 54. The arc-shaped block 53 and the arc-shaped plate 52 return to their original positions under their own elasticity, releasing the clamp on the upright. Then, the upright can be pulled out from the connecting sleeve 4. Finally, the fixing bolt 10 of the upper fixing ring 2 is loosened, allowing the upper fixing ring 2 and the lower fixing ring 8 to detach from the surface of the steel frame of the scaffold body 1, thus completing the dismantling.
