Description

Technical Field

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

[0002] Disc-lock scaffolding, also known as "socket-type disc-lock steel pipe scaffolding," is a type of scaffolding connected by sockets and disc locks. Its core feature is that connecting discs are welded to the uprights, and locking joints are welded to both ends of the horizontal and diagonal members. By inserting the locking joints into the connecting discs and tightening them with wedge-shaped pins, a stable, geometrically invariant system is formed.

[0003] In existing disc-lock scaffolding, the disc lock heads on the horizontal bars are welded to the horizontal bars. When the disc lock heads are damaged, cutting the horizontal bars to replace them will shorten the horizontal bars, which does not meet the construction requirements. Therefore, most of the time, the horizontal bars and disc lock heads are scrapped as a whole, resulting in a waste of resources. Based on this, a scaffolding connector is provided. Utility Model Content

The locking pin 402 is vertically and movably installed on the inner side of the two horizontal parts at the front end of the concave lock head seat 401. The convex hole groove 406 is opened in the middle of the rear circular seat part of the concave lock head seat 401 and completely penetrates the front and rear ends of the rear circular seat part of the concave lock head seat 401. The concave lock head seat 401 has a round seat portion that fits against the end face of the crossbar 1 and the nut seat 2. The connecting bolt 408 passes through the convex hole groove 406 and is threadedly connected to the nut seat 2 to achieve a detachable connection between the concave lock head seat 401 and the crossbar 1. Lock assembly 4 also includes a reinforcing sleeve 403, an annular groove 404, and a sealing ring 405; The reinforcing sleeve 403 is fixed to the rear end of the circular seat of the concave lock head seat 401, and the reinforcing sleeve 403 is sleeved on the outside of the crossbar 1. The annular groove 404 is integrally formed on the inner side of the rear end of the reinforcing sleeve 403. The sealing ring 405 is installed on the inner side of the reinforcing sleeve 403. The sealing ring 405 is tightly fitted with the outer wall of the crossbar 1 to achieve the sealing operation between the reinforcing sleeve 403 and the crossbar 1.

[0015] In this embodiment: when the lock assembly 4 is connected to the crossbar 1, its operation method is as follows: First, the sealing ring 405 is installed inside the annular groove 404. Then, the reinforcing sleeve 403 is aligned with the end of the crossbar 1 and inserted. Finally, the reinforcing sleeve 403 and the sealing ring 405 are fitted onto the outside of the crossbar 1, and the sealing ring 405 is tightly fitted with the crossbar 1 to ensure the seal between the reinforcing sleeve 403 and the crossbar 1.
