Description

Technical Field

[0001] The utility model relates to the technical field of life jacket accessory testing, and more specifically, to a tension and pressure load testing device. Background Art

[0002] A life jacket, also known as a life vest, is a life-saving garment with a similar design to a vest. It is made of nylon fabric or neoprene, buoyancy material or inflatable material, reflective material, etc. The general service life of a life jacket is 5-7 years. It has sufficient buoyancy when worn on the body so that the head of a person who falls into the water can be exposed to the water surface. The inflatable life jacket is made of high-strength waterproof material, similar to the principle of an inflatable life buoy or swimming ring. In order to ensure the reliability of the inflatable life jacket mouthpiece, the inflatable life jacket mouthpiece should be tested for its tensile and compressive load qualification during quality inspection. However, during the test, the life jacket mouthpiece needs to be clamped and fixed first, and then the clamped life jacket mouthpiece is tested for tensile and compressive load in turn. The test operation is relatively cumbersome, which affects the tensile and compressive load test efficiency of the life jacket mouthpiece. In view of this, we propose a tensile and compressive load test device. Utility Model Content

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The utility model places the elbow portion of the life jacket mouth blow pipe in the limiting groove of the elbow carrier, places the straight pipe portion of the life jacket mouth blow pipe on the straight pipe carrier, uses a longitudinal motor to drive the longitudinal stud to rotate forward, drives the transmission frame b and the straight pipe pressure seat to press down and contact the top side of the straight pipe portion of the life jacket mouth blow pipe, and uses the longitudinal spring to continuously contract to make the transmission frame b continue to press down until the pressure on the life jacket mouth blow pipe gradually increases to a maximum value. If the life jacket mouth blow pipe is broken, the test fails. If the life jacket mouth blow pipe is not broken, the pressure load test passes.
