Description

Technical Field

[0001] The utility model belongs to the technical field of pressure testing devices, in particular to a quick-jointing pressure testing device for automobile hoses. Background Art

[0002] Hydraulic hoses, also known as hydraulic oil hoses, hydraulic hoses, high-pressure hoses, hydraulic pipes, steel wire high-pressure hoses, wire braided hoses, and wire-wound hoses, are generally divided into wire braided hydraulic hoses and wire-wound hydraulic hoses. Existing devices for hose pressure testing, when in use, generally provide sealing joints at the connection ends to maintain a stable connection between the hose and the test interface for auxiliary connection and fixation. However, due to problems with the production process or equipment, the produced automotive hoses may have low pressure resistance during testing, causing the hoses to rupture during pressure testing, resulting in splashing of hydraulic oil and posing a safety hazard to operators around the equipment, resulting in low safety.

[0003] After searching, for example (authorization announcement number CN212989050U) a pressure test device for a hydraulic hose, the fixture includes a clamp body, a sealing joint, and a water inlet joint. The clamp body is cylindrical, and a cylindrical channel is provided through the center of the clamp body. One end of the cylindrical channel is connected to a joint body, and the joint body includes a joint pipe and a lock pipe nut. The joint pipe is rotatably plugged into the through hole. The joint pipe is hollow and has a protrusion on the outer wall that is interference-engaged with the hose. The lock pipe nut is a through-hollow cylinder with the same inner diameter as the clamp body. A plurality of circular holes are provided on one bottom surface of the lock pipe nut. A retractable fixing rod is also provided on the surface of the lock pipe nut. The two ends of the fixing rod are interference-engaged with the circular holes, and the fixing rod is provided with external threads on the side facing the lock pipe nut. This device solves the problem of unstable connection when the existing equipment is used. However, this device cannot be used for pressure resistance testing of automobile hoses and cannot be used to seal the test equipment. When the hose ruptures, hydraulic oil splashes and the hose flies, affecting the staff around the equipment and reducing the safety of the device. Utility Model Content
