Air pressure type pipeline connector

Abstract

The invention discloses an air pressure type pipeline connector. The air pressure type pipeline connector comprises an outer ring, a middle ring, a movable block, a sliding block and a soft rubber inner ring installed on an external pipeline in a sealing and sleeving mode, wherein the outer ring, the middle ring and the soft rubber inner ring are coaxially arranged, the inner diameter of the outer ring, the inner diameter of the middle ring and the inner diameter of the soft rubber inner ring become smaller in sequence, and the outer ring and the middle ring are fixedly connected through a sliding groove; the movable block is arranged in the sliding groove and is in sliding fit with the sliding groove in a sealing mode, the inner end of the movable block is in elastic connection with the inner wall of the outer ring, and a groove allowing the outer end of the movable block to be inserted therein is formed in the soft rubber inner ring; a first air inlet channel is formed in the wall of the sliding groove, a first one-way air valve allowing air to be introduced into the sliding groove in one direction is arranged in the first air inlet channel, the inner end of the first air inlet channel is communicated with the sliding groove and located between the inner end of the movable block and the inner wall of the outer ring, and the outer end of the first air inlet channel is communicated with an air chamber. By the adoption of the air pressure type pipeline connector, on the basis that convenient detachment is guaranteed, high airtight performance and high watertight performance can be maintained in a vibration environment.

Description

Technical field [0001] The invention relates to a pipe connection device, in particular to a pneumatic pipe connection piece. Background technique [0002] The pipe connector is a device that splices two pipes together. In order to ensure the airtight and watertight connection of the pipe, it is often necessary to increase the pressing force of the pipe connector on the two pipes. At present, the commonly used structure is generally a screw connection structure or elastic Although the buckle structure and the screw connection structure have shock resistance and relatively stable air-tightness and water-tightness, when they are used in occasions that require frequent assembly and disassembly, they are prone to slippage and damage, reducing air-tightness and water trapping; for elasticity Although the buckle structure has better assembly and disassembly convenience, it is often misaligned after encountering strong vibrations, resulting in gaps, which greatly reduces air tightness a...

[0002] The pipe connector is a device for splicing two pipes together. In order to ensure the airtight and watertight connection of the pipeline, it is often necessary to increase the compression force of the pipe connector on the two pipes. At present, the commonly used structures are generally screwed structures or elastic joints. Although the buckle structure and the screw structure have shock resistance and relatively stable air and water tightness, when they are used in occasions that require frequent assembly and disassembly, they are prone to slipping and damage, which reduces air-tightness and water loss; for elasticity The buckle structure, although it has good assembly and disassembly convenience, often displaces and creates gaps after encountering strong vibrations, which greatly reduces air-tightness and water-tightness
