Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a scaffolding connecting piece. Background Art

[0002] Scaffolding connectors are an indispensable and important part in building construction. Their main function is to connect the various parts of the scaffolding, such as vertical poles, horizontal poles, diagonal poles, etc., tightly and firmly together to form a complete scaffolding structure that can withstand various loads.

[0003] For example, the Chinese utility model patent disclosed in the publication number CN212715878U: a convenient scaffolding connector, the application connects the left clamp and the right clamp in a hinged manner. When in use, the left clamp and the right clamp can be directly connected to the outside of the support rod, and the support rod does not need to be put on from one end of the support rod, which is convenient for the use of the first connector. First of all, the existing scaffolding connectors are mostly snap-on structures, which can be directly fixed at any position on the scaffolding rod body. Therefore, the structure in the application needs to be installed twice separately, making the operation process and It is not easy. Secondly, the left-side clip and the right-side clip are connected by fixed bolts. When the scaffolding is in use, it is often affected by various vibrations, such as vibration of construction machinery, blowing of wind, etc. These vibrations will cause lateral movement of the bolt joints. Although only a small amount of movement occurs, over a long period of accumulation, these movements will gradually overcome the friction between the threads, causing the bolts to loosen by themselves, which will cause the connecting fasteners and the scaffolding rods to loosen, resulting in unstable connections between the scaffolding rods, which can easily lead to production safety accidents.

[0021] like Figure 2-Figure 3 As shown, a washer groove 9 is provided at one end of the bowl buckle 4, a slot 10 is provided at the bottom of the washer groove 9, and a plurality of tooth grooves 11 are provided at the bottom of the washer groove 9 located at the outer periphery of the slot 10. A limit block 12 is fixedly installed at one end of the connecting screw 5, and one end of the connecting screw 5 is inserted and installed in the pill hole 2 through the limit block 12, and the other end of the connecting screw 5 is inserted and installed in the slot 10. With the arrangement of the connecting screw 5 and the nut 6, the bowl buckle 4 can be closed and connected with one end of the base 1, so that the base 1 and the bowl buckle 4 are clamped and fixed on the steel pipe;

[0022] like Figure 2-Figure 4As shown, the nut 6 is threadedly connected to the connecting screw 5, and a fixing ring 13 is fixedly installed on the outside of the nut 6. The fixing ring 13 is arranged on the outside of the nut 6, so that the limiting ring 8 can be movably installed on the outside of the nut 6. A sleeve 16 is fixedly installed on the upper end of the limiting ring 8. Both the limiting ring 8 and the sleeve 16 are provided with a through groove with a regular hexagonal cross section, and the longitudinal section of the sleeve 16 is an inverted L shape. A plurality of second limiting teeth 15 are fixedly installed on the lower end of the limiting ring 8. The limiting ring 8 is inserted and installed on the outside of the nut 6 through the sleeve 16. The nut located between the fixing ring 13 and the limiting ring 8 6 is set with a compression spring 17, and a plurality of first limiting teeth 14 are fixedly installed on the top and bottom of the limiting washer 7.
