AI Technical Summary

Technical Problem

Existing connectors used for grooved pipe installation are usually designed for specific sizes and cannot meet the connection needs of pipes of different sizes, resulting in high procurement costs and complex inventory management.

Method used

A connecting piece is designed, which includes two pipe bodies, each of which is provided with a card slot, an L-shaped slide groove and a limit rod. The connection of grooved pipe fittings with different diameters is achieved through the cooperation of the rotating wheel and the limit rod, and the stability and sealing are enhanced through the fixing mechanism of the slide rod and the splint.

Benefits of technology

It achieves reliable connection of grooved pipe fittings with different diameters, reduces procurement costs, simplifies inventory management, and improves connection stability and sealing.

Abstract

The utility model discloses a connecting piece for groove pipe fitting installation, which comprises two pipe bodies, clamping grooves are arranged on the outer surfaces of one sides of the two pipe bodies close to each other, and an upper arc-shaped plate a and a lower arc-shaped plate b which are symmetrically arranged are arranged on the upper portion and the lower portion of the joint of the two pipe bodies. L-shaped sliding grooves which are symmetrically formed are formed in the two sides of the inner wall of the upper arc-shaped plate a and the two sides of the inner wall of the lower arc-shaped plate b correspondingly, two clamping grooves are formed in the positions, corresponding to the four L-shaped sliding grooves, of the outer surfaces of the two pipe bodies correspondingly, and first fixing mechanisms are arranged in the four L-shaped sliding grooves and the two clamping grooves; the first fixing mechanism comprises four L-shaped limiting rods symmetrically installed in the four L-shaped sliding grooves and the two clamping grooves in a sliding mode, clamping teeth are arranged on the outer sides of the four L-shaped limiting rods, and four rotating wheels meshed with the clamping teeth on the four L-shaped limiting rods are arranged on the upper arc-shaped plate a correspondingly. According to the connecting piece, the first fixing mechanism is arranged, so that the connecting piece can conveniently connect pipe bodies with different sizes.
