High-pressure airtightness detection device for automobile brake hose

Abstract

The invention provides a high-pressure airtightness detection device for an automobile brake hose. The high-pressure airtightness detection device comprises a device body, wherein a limiting fixing box in the left-right direction is arranged at the bottom part of the device body, and a positive and negative threaded rod in the left-right direction is fixedly installed in the middle of the bottom part in the limiting fixing box through a bearing; the ends of the left side and the right side of the right-and-left threaded rod are sleeved in a limiting mode and locked with adjusting rotating wheels through bolts, and limiting adjusting plates in the front-and-back direction are fixedly installed on the left side and the right side of the right-and-left threaded rod; and four brake hose pieces which are arranged front and back in the left-right direction are inserted between the limiting adjusting plates from top to bottom in a limiting mode. Through the arrangement of the limiting fixing box, positive and negative threaded rods can be fixedly installed in the limiting fixing box through bearings conveniently to fixedly install limiting adjusting plates, an external water supply pipeline can be fixedly installed through threads conveniently to enable internal water to submerge the brake hose piece, and whether bubbles emerge from the brake hose piece or not and whether the airtightness problem exists or not can be directly observed conveniently.

Description

technical field [0001] The invention belongs to the technical field of automobile brake hoses, in particular to a high-pressure airtightness detection device for automobile brake hoses. Background technique [0002] Automobile brake hose is a component in the automobile braking system. Its main function is to transmit the braking medium in the automobile braking to ensure that the braking force is transmitted to the automobile brake shoe or brake caliper to generate braking force, so that the brake Active at any time. There is a permanent connection between the brake hose and the brake hose joint, which is achieved by crimping or cold extrusion deformation of the joint part relative to the hose. [0003] Based on the above, the inventors found that the existing high-pressure airtightness detection device for automobile brake hoses is inconvenient to adjust the limit fixing block according to the length of the automobile brake hose, and it is inconvenient to quickly dock and...
