Air breathing apparatus is widely used in fire fighting, chemical industry, shipping, petroleum, smelting, warehouse, laboratory, mining and other departments. After the air breathing apparatus is produced, it needs to be tested.

[0003] Although the existing device can realize the sealing test and the tensile test, its structural property is poor and it is not possible to realize the tensile test of the air supply pipe on the air respirator while realizing the sealing test. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides an air respirator comprehensive performance tester to solve the problem that although the existing device can realize sealing test and tensile test, its structure is poor and it is impossible to realize the tensile test of the air supply pipe on the air respirator while realizing the sealing test.

[0005] The purpose and function of the air respirator comprehensive performance tester of the utility model are achieved by the following specific technical means:

[0006] The air respirator comprehensive performance tester comprises a mounting seat, which is a rectangular block structure, a seat body is fixed on the front end surface of the mounting seat, an air bottle is plugged on the seat body, and an air supply pipe is connected to the air bottle.

[0007] Furthermore, the seat body is a concave structure, a circular hole is provided on the top surface of the seat body, the diameter of the circular hole is equal to the outer diameter of the cylindrical part of the air bottle, and a limiting hole is provided at the bottom of the seat body for limiting the downward movement of the air bottle.

[0008] Furthermore, a detection part is fixed on the mounting seat, and the detection part consists of a mounting block, an electric cylinder, a water storage box, a switch and an auxiliary arm. The mounting block is fixed to the front end surface of the mounting seat. The mounting block is a rectangular block structure. Two electric cylinders are welded to the top surface of the mounting block, and the upper ends of the two electric cylinders are fixed to the bottom end surface of the water storage box.

[0009] Furthermore, the water storage box is a rectangular box-shaped structure, the water storage box is made of transparent glass, and water is contained in the water storage box.

[0010] Furthermore, the water storage box is located directly below the air bottle. When the two electric cylinders are extended, the connection position of the air bottle with the air supply pipe is in contact with the water in the water storage box.

[0011] Furthermore, an iron auxiliary arm is fixed to the top surface of the water storage box. The auxiliary arm is an L-shaped structure and is provided with a slot matching the upper joint of the air supply pipe.

[0012] Furthermore, a switch for controlling two electric cylinders is fixed on the right end surface of the mounting seat, and the switch is electrically connected to an external power supply.

[0013] Furthermore, two first connection blocks are welded to the bottom end surface of the seat body, two rollers are rotated on the two first connection blocks, and both rollers are in contact with the air supply pipe.

[0014] Furthermore, a scale is provided on the front end surface of the mounting seat, and the scale contacts the rear end surface of the water storage box.

[0015] Furthermore, a supporting part is fixed on the mounting seat, and the supporting part is composed of a second connecting block, a threaded rod and a supporting block.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] Through the setting of the detection part, a switch is used to control the extension of the two electric cylinders. When the two electric cylinders are extended, the water storage box can be pushed to move upward. After the water storage box moves upward, the moisture in the water storage box contacts the connection between the air bottle and the air supply pipe. At this time, a sealing test of the contact between the connection between the air bottle and the air supply pipe is realized, and the air supply pipe is stretched at this time, and a stretching test of the air supply pipe can also be realized. During the stretching test, the stretching data can be read by cooperating with the top edge of the water storage box and the scale. Compared with the existing device, the present device can realize sealing test and stretching test.

[0018] By setting the supporting part, when the placement position is not flat enough, horizontal adjustment can be achieved by rotating the threaded rod, thereby ensuring the stability of the device.

[0019] By providing the first connecting block and the two rollers, under the guidance of the two rollers, it is possible to avoid blockage caused by excessive bending angle of the air supply pipe during testing. BRIEF DESCRIPTION OF THE DRAWINGS
