[0002] An air pump is a device that inflates the air by running a motor. Therefore, in order to ensure that the pressure value of the air pump when inflating is at a standard value, it is necessary to use a corresponding testing device to test the air pump.

[0003] After searching, the publication number is CN219366286U, which discloses a portable automatic testing device for an air pump, which is provided with a test box, a handle is fixed on the top of the test box, and a limit block is set on the top of the handle; an air inlet nozzle is fixed to the side of the test box, and an exhaust port is set at the top edge of the test box; it includes: a piston plate, which is movably arranged inside the test box, a limit plate is fixed on the test box on the side of the piston plate, and a rack is set on the side of the piston plate, and a gear is meshed on the top of the rack.

[0004] In the process of realizing the utility model, the inventors found that there are at least the following problems in the prior art that have not been solved: when gas is filled into the test box, the piston plate and the rack can be pushed to move, and then the movable shaft can be driven to rotate through the meshing transmission between the rack and the gear. In this way, the pressure value can be viewed more intuitively through the rotation of the pointer. The gears and racks are easily worn out by the transmission structure such as the gears and racks, which affects the detection. In addition, the cost is high and the weight is heavy, which is not suitable for widespread use.

[0017] See also Figure 1-Figure 2 The utility model provides a technical solution: a portable automatic testing device for an air pump, comprising a testing cylinder 1 and a piston 11, wherein the piston 11 is slidably connected to the inside of the piston 11, a connecting rod 12 is vertically fixedly installed in the middle of the upper surface of the piston 11, and a scale line 13 is vertically engraved on the outer side of the connecting rod 12, an inflation joint 14 is fixedly installed in the middle of the bottom side of the testing cylinder 1, and the air outlet end of the inflation joint 14 is connected to the bottom end of the inside of the testing cylinder 1, a guide groove 17 is penetrated in the middle of the inner wall of the top end of the testing cylinder 1, the connecting rod 12 is slidably connected to the guide groove 17, a sealing ring 18 is bonded to the outer side of the piston 11, and the sealing ring 18 is in contact with the inner wall of the testing cylinder 1.

[0018] In this technical solution, the air outlet pipe of the air pump to be tested can be connected to the test cylinder 1 through the inflation joint 14, so that the air discharged from the air pump can be introduced into the test cylinder 1. As the air volume in the test cylinder 1 increases, the piston 11 can be pushed to move upward in the test cylinder 1, and the connecting rod 12 can be further pushed upward. The scale line 13 on the front side of the connecting rod 12 allows the staff to detect the air volume of the air pump within a specified time. The structure is simple and convenient.
