Description

Technical Field

[0001] This utility model belongs to the field of diving breathing apparatus technology, specifically relating to a differential pressure testing device for diving breathing apparatus. Background Technology

[0002] An air respirator is a self-contained open breathing apparatus that uses positive pressure compressed air. When a worker exhales, the air passes through a full-face mask and is released into the atmosphere via a breathing valve. When the worker exhales, an appropriate amount of fresh air is supplied through the gas storage cylinder, the pressure reducer, and the soft tube supply valve, and then through the full-face mask, drawing the air into the lungs, completing the entire breathing cycle. During this breathing cycle, because there are two inhalation valves and one exhalation valve inside the full-face mask, which open in one direction during breathing, the airflow always moves in one direction, constituting the entire breathing cycle.

[0003] When using existing technology, it is necessary to connect it to a diving breathing apparatus to conduct differential pressure tests. The breathing apparatus needs to be placed stably to avoid the need for manual support. When using the testing device, it is inconvenient to place the notebook for recording and the tools for maintenance. Utility Model Content

[0039] The structure and working principle of the test structure 3, which consists of a piston structure, a motor structure, a crank-connecting rod structure, a pressure sensor, a pressure gauge, a drive shaft, and a transmission column, have been disclosed in a diving respirator differential pressure testing device disclosed in Chinese patent application number 202121396238.2. Its working principle is that the motor drives the drive shaft to rotate, which in turn drives the first transmission rod to rotate. The first transmission rod, under the action of the second transmission rod, drives the transmission block to move up and down. The transmission block drives the transmission column to move up and down. The transmission column drives the piston plate to perform piston movement. The piston plate squeezes the gas in the air chamber out of the air exchange port 5 through the air pipe 6 or draws the air in the respirator into the air chamber. The pressure sensor detects the air pressure in the air chamber and transmits it to the pressure gauge for display.

The test structure 3 is activated to test the pressure difference of the diving device. The base 41 is installed on one side of the base plate 2. The diving device is placed inside the limiting cylinder 42. The telescopic structure 48 applies a pushing force to the clamping plate 43, so that the clamping plate 43 can clamp and fix the diving device, making it stable during testing. The moving rod 482 moves within the sleeve 481, and the compression spring 483 is compressed to generate a rebound force, thereby applying a pushing force to the clamping plate 43. When the clamping plate 43 moves, the limiting slide plate 47 is in the limiting position. The sliding groove 44 moves within the slot, which can limit and guide the clamping plate 43. The fixed threaded post 45 engages with the fixed threaded groove 46, which can easily disassemble and assemble the limiting cylinder 42. Notebooks and repair tools are placed inside different storage drawers 75, and then pushed to move in the storage slots 72 in the storage box 71 until the side plate 78 covers the storage slots 72, which can easily store items. The connecting magnetic sheet 77 and the fixed magnetic block 74 attract each other, which can easily fix the position of the side plate 78, making the storage more stable. The sponge pad 76 can provide soft protection, and the soft pad 73 can prevent items from being worn, providing good protection.
