Description

Technical Field

[0001] This utility model relates to the field of mechanical scaffolding connection technology, specifically to an adjustable-height scaffolding connector for construction engineering. Background Technology

[0002] Scaffolding connectors are key components in scaffolding systems used to connect and fix various members (such as uprights, horizontal bars, and diagonal braces) or parts to form a stable overall structure. They play a central role in the assembly, stabilization, and safety performance of scaffolding, directly affecting its load-bearing capacity and overall stability. With the rapid development of high-rise and multi-story buildings, scaffolding is widely used due to its simple structure, convenient assembly and disassembly, and reasonable force transmission. The safety and reliability of scaffolding are paramount, and connectors are crucial components ensuring its stability. Many steel pipe scaffolding collapses both domestically and internationally over the years have been caused by improper installation of connectors or failure to promptly remedy the situation after their removal. Therefore, higher requirements are placed on the performance and safety of scaffolding connectors.

[0003] In existing technologies, scaffold connectors are simple in construction and internal structure. Under load, they are not only prone to deformation, but also prone to loosening of internal nodes and the entire device. At the same time, the inner wall of the metal rod connecting sleeve is not smooth enough, which increases the instability of the entire scaffold connector device and also increases the risk factor for workers using scaffolds, bringing certain safety hazards. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable-height scaffold connector for construction engineering. It not only solves the problem that the connector of adjustable-height scaffolds in the prior art has a simple structure, which leads to loosening of internal nodes and the entire device, but also that the simple internal mechanical structure results in poor stability of the scaffold and easy safety hazards.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable height scaffolding connector for construction engineering, including a limiting mechanism and mounting holes, wherein device components are respectively provided on the right side and below the limiting mechanism.

[0008] The device components include a metal shell, a threaded metal rod extending through the left side, a displacement block at one right end of the threaded metal rod, and the two being movably connected by a rotating shaft. A first spring is located to the right of the displacement block and is fixedly connected to the right side of the displacement block. A limit groove is located to the right of the first spring, and the first spring connects to the recess of the limit groove. A piston is located to the right of the limit groove, and a limit device is located to the right of the piston. A second spring is located to the right of the limit device and is fixedly connected to the left end of the second spring. A pulley is located below the limit device, and a pulley groove is located below the pulley. A third spring is located below the pulley groove.

[0009] The limiting device includes a button, a metal rod connected below the button, the metal rod being embedded in a movable groove, a limiting block being fixedly connected below the movable groove, and a limiting pin being provided on the upper left of the limiting block, the limiting pin being fixedly connected to the metal shell.

[0010] Preferably, a displacement block is connected to the right side of the metal threaded rod. By rotating the threaded rod, the displacement block moves to the left, thereby adjusting the height.

[0011] Preferably, the limiting device is squeezed by the buffer device and moves to the left, squeezing the second spring. When it reaches the movable groove, it is subjected to the upward force of the third spring, so that the limiting device is fixed at the movable groove.

[0012] Preferably, the limiting block is provided with a groove for engaging with the limiting pin, and the metal rod can move up and down relative to the movable groove during use.

[0013] (III) Beneficial Effects

[0014] This utility model provides an adjustable-height scaffold connector for construction engineering. It offers the following advantages: This adjustable-height scaffold connector for construction engineering, through improvements to the internal limiting and buffering mechanisms, and the coordinated use of the limiting devices, employs a metal threaded rod that moves a rotating shaft to move a displacement block to the left, compressing a spring and causing the piston-driven limiting device to move into the movable groove, thus achieving height adjustment. Simultaneously, the coordinated movement of various components within the mechanical setup effectively prevents instability, significantly reduces safety risks for users, and lowers costs associated with damage due to the simple internal structure of the device.

[0023] In use, mounting hole 2 is installed on the scaffolding.
