Description

Technical Field

[0001] This utility model relates to the field of fastener technology, specifically to a scratch-resistant steel fastener that is easy to disassemble. Background Technology

[0002] Scaffolding is frequently used in construction. The steel pipes of the scaffolding need to be connected and installed with fasteners. A search revealed a Chinese patent publication number CN107916777A that discloses an anti-slip steel fastener for construction. Although this fastener can prevent the loss of fasteners such as fasteners or nuts by rotating the first and second screws to the circular groove and using the first and second nuts for fixing, thus reducing losses, this fastener can only connect and fix steel pipes of a fixed diameter. When the diameter of the steel pipe is small, a gap will exist between the fastener and the outer wall of the steel pipe, making it impossible for the fastener to effectively fix the steel pipe. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an easily disassembled, scratch-resistant steel fastener, which solves the problem mentioned in the background art that existing fasteners can only connect and fix steel pipes of a fixed diameter.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a scratch-resistant steel fastener that is easy to disassemble, comprising a lower fastener, an upper fastener, a clamping block, and a connecting bolt. The upper fastener is positioned above the lower fastener, and the top two ends of the lower fastener are tightly fitted to the bottom two ends of the upper fastener. An adjusting bolt is positioned on the top of the upper fastener, and the outer wall of the adjusting bolt is threadedly connected to the inside of the upper fastener. One bottom end of the adjusting bolt is connected to the clamping block. Both ends of the upper and lower fasteners are provided with ear plates, and the ends of the ear plates are provided with slots. Connecting bolts are inserted into the slots at the ends of the ear plates, and one bottom end of the connecting bolt is threadedly connected to a nut.

[0005] Preferably, the upper fastener has a groove at its inner top, and the clamping block is embedded in the groove on the surface of the upper fastener. This facilitates adjustment according to steel pipes of different diameters. When the diameter of the steel pipe is small, the clamping block can move inward. By adjusting the bolt, the clamping block can be made to fit tightly against the surface of the steel pipe, thereby achieving effective clamping of smaller diameter steel pipes. This allows the fastener to adapt to steel pipes of various diameters, improving the versatility and applicability of the fastener.

[0006] Preferably, one end of the surface of the connecting bolt and the nut is a hemispherical smooth structure, and the end surfaces of the connecting bolt and the nut are provided with hexagonal grooves. The hemispherical smooth shape structure helps to achieve the effect of scratch prevention.

[0007] Preferably, there is a gap between the ear plates on one side of the upper fastener and the lower fastener, and the ear plates on the other side of the upper fastener and the lower fastener are tightly fitted together. Adjacent fasteners can be fixed by inserting the ear plates into the gap and then by connecting bolts and nuts, thereby realizing the series connection of multiple sets of fasteners. When building large scaffolding, multiple fasteners can be combined together in this connection method to form a longer connection section, thereby improving the overall stability and flexibility of the scaffolding.

[0008] Preferably, the bottom surface of the clamping block is provided with a rubber coating. The bottom surface of the clamping block has an arc-shaped structure. The rubber coating on the bottom surface of the clamping block can effectively prevent the clamping block from scratching or abrading the surface of the steel pipe when clamping it. The rubber coating has good flexibility and cushioning performance, which can reduce direct contact and friction with the surface of the steel pipe during the clamping process, thereby protecting the surface quality of the steel pipe.

[0009] Preferably, the nut has a split structure, consisting of a nut body and a cap. The bottom of the nut body has a protruding structure, and the outer wall of the protruding structure at the bottom of the nut body is threaded to the inner wall of the cap. Both the cap and the nut body are threaded to the connecting bolt. The nut body and the cap can be screwed together, and at the same time, they also serve as a protective sleeve.

[0010] This utility model provides an easily disassembled, scratch-resistant steel fastener. It has the following advantages:

[0011] (1) The easy-to-disassemble anti-scratch steel fastener, when used, is installed on the outside of the scaffold pole by the upper fastener and the lower fastener, and then the upper fastener and the lower fastener can be connected and fixed to each other by the connecting bolt and nut. When the diameter of the scaffold pole is small and the fastener is loose, the adjusting bolt is rotated so that the adjusting bolt can drive the clamping block to move, and then the clamping block can clamp and fix the scaffold pole between the upper fastener and the lower fastener inward. This makes the fastener suitable for fixing scaffold poles of various diameters, and thus improves the applicability of the fastener.

[0012] (2) The easy-to-disassemble anti-scratch steel fastener has a groove between the upper fastener and the lower fastener. By inserting the adjacent fastener ear plate into the groove between the upper fastener and the lower fastener, the two sets of fasteners can be connected by connecting bolts and nuts. In this way, multiple sets of fasteners can be connected to each other, which is beneficial to improving the practicality of the fastener.

[0013] This solves the problem that existing fasteners can only connect and fix steel pipes of a fixed diameter. Attached Figure Description
