DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , a tooling for solenoid valve performance testing, including a tooling base 1. On both sides of the outer surface of the tooling base 1, side columns 2 are fixedly installed. Inner grooves 21 are opened inside the two side columns 2, and a fixing structure 3 is arranged inside the two inner grooves 21; the fixing structure 3 includes two first springs 31, two threaded columns 32, and two sliders 36. A clamping upper cover 33 is sleeved on the outer surface of the two threaded columns 32. The bottom of the clamping upper cover 33 is fixedly connected to one end of the top of the first spring 31. Fastening nuts 34 are threadedly installed on the outer surface of the two threaded columns 32. On both sides of the bottom of the clamping upper cover 33, downward wedges 35 are fixedly installed. On the top of the two sliders 36, a transverse wedge 38 is fixedly installed. On one side of the two transverse wedges 38, a sealing gasket 39 is fixedly installed. On one side of the two sliders 36, a second spring 37 is fixedly installed.

[0021] Please refer to Figures 2-4 , the hypotenuses of the two transverse wedges 38 are in contact with the hypotenuses of the two downward wedges 35. On both sides of the top of the tooling base 1, chutes 4 are opened, and the two chutes 4 are slidably connected to the sliders 36. One end of the two second springs 37 is fixedly connected to the inner wall of the two chutes 4. On both sides of the top of the tooling base 1, limit plates 6 are fixedly installed, and the two limit plates 6 are in contact with the two sealing gaskets 39.

[0022] When the downward wedges 35 on both sides below the clamping upper cover 33 move downward, since the hypotenuse of the downward wedge 35 is in contact with the hypotenuse of the transverse wedge 38, when the downward wedge 35 moves downward, the two transverse wedges 38 drive the sliders 36 to move towards the solenoid valve, so that the sealing gasket 39 can cover the bottom of the solenoid valve.

[0023] Please refer to Figures 1-4 , a test hole 5 is opened on the top of the tooling base 1, and the test hole 5 can be connected to the solenoid valve. A threaded hole 7 is opened on one side of the outer surface of the tooling base 1, and an air pipe 8 is threadedly installed inside the threaded hole 7.

[0024] The test hole 5 is communicated with the threaded hole 7. After the solenoid valve is connected to the test hole 5, the air pipe 8 is connected to the threaded hole 7. After the threaded hole 7 is ventilated, the solenoid valve can be tested.

[0025] Working principle: When a tooling for solenoid valve performance testing is in use, first connect the solenoid valve to the test hole 5, and then turn the fastening nuts 34 on both sides downward so that they move downward on the threaded posts 32. Thereby, the clamping upper cover 33 can press the first spring 31 and press the solenoid valve. At the same time, the downward wedge blocks 35 on both sides below the clamping upper cover 33 move downward. Since the inclined sides of the downward wedge blocks 35 are in contact with the inclined sides of the transverse wedge blocks 38, when the downward wedge blocks 35 move downward, the two transverse wedge blocks 38 drive the slider 36 to move towards the solenoid valve, thereby enabling the gasket 39 to cover the bottom of the solenoid valve. Finally, connect the air pipe 8 to the threaded hole 7, and after the threaded hole 7 is ventilated, the solenoid valve can be tested.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
