[0014] In another aspect, the present invention provides an air switch life tester, comprising:

[0015] Machine;

[0016] A clamping assembly, arranged on the machine platform, and used for clamping the bottom of the air switch;

[0017] A lifting frame, arranged on the machine platform;

[0018] The detection device is arranged on the machine platform, and the detection device is the air switch detection device mentioned above.

[0019] Preferably, the first driving component and the second driving component are both arranged at an output end of the lifting frame, so that the heights of the first driving component and the second driving component can be adjusted through the lifting frame.

[0020] Preferably, the lifting frame comprises:

[0021] A gantry frame is fixed on the machine platform;

[0022] A lifting screw rod is vertically threadedly connected to the gantry;

[0023] A connecting plate, the bottom end of the lifting screw is rotatably connected to the connecting plate, and the first driving component and the second driving component are fixed to the connecting plate.

The elastic member is driven by the first driving member, and the first push plate is driven by the elastic member. Then, the first push plate pushes the air switch to move upward in an arc, so that the air switch is in a closed state. Since the elastic member has elastic forces in the first direction and the second direction, the first push plate will not get stuck on the arc surface of the air switch, and will push the air switch upward along the arc surface, so that the air switch rotates upward along the arc surface to be in a closed state. The detection device will record the on-off performance of the air switch. Then, the second driving member drives the second flicking member to push the air switch, and the air switch rotates downward along the arc surface under the action of its internal spring, so that the air switch is in an open state. The detection device records the on-off performance of the air switch again to complete a complete test, and then repeats the test in a cycle. The air switch detection device and the air switch life tester provided by the present invention are simpler and more stable than the existing ones, and the manufacturing cost is low. During the test, the test efficiency is improved by the driving of the first driving member and the second driving member. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] Embodiment 1

[0050] As is known to all, the closing and opening switches of the air switch 100 are arc-shaped. Usually, the air switch 100 is closed when it is moved upward in an arc shape, and is opened when it is moved downward in an arc shape. When it is moved upward in an arc shape, a large force is required, and when it is moved downward, only a light push is required, and the air switch 100 will be easily opened under the action of the spring inside the air switch 100.

[0051] like Figure 1 As shown, the present invention provides an air switch detection device, comprising:

[0052] A first driving component 200;

[0053] A first toggle component 1, disposed at an output end of the first driving component 200, and used to toggle the air switch 100;

[0054] A second driving component 300;

[0055] The second toggle component 3 is disposed at the output end of the second driving component 300 and is used to toggle the air switch 100 ; preferably, the second toggle component 3 is a push plate.

[0056] The detection device 400 is connected to the air switch 100 and is used to detect the on-off performance of the air switch 100 in a closed or open state;

[0057] The first shifting component 1 includes an elastic component 12 and a first push plate 11 , the output end of the first driving component 200 is connected to the elastic component 12 , the elastic component 12 is connected to the first push plate 11 , and the elastic component 12 has elastic force along the first direction X and the second direction Y.

[0058] Specifically, the working principle of the embodiment of the present invention is to place the air switch 100 between the first toggle component 1 and the second toggle component 3, drive the elastic component 12 through the first driving component 200, and the elastic component 12 drives the first push plate 11, and then the first push plate 11 pushes the air switch 100 to move upward in an arc so that the air switch 100 is in a closed state. The elastic force of the first push plate 11 will not be stuck on the arc surface of the air switch 100, and the air switch 100 will be pushed upward along the arc surface, so that the air switch 100 rotates upward along the arc surface and is in a closed state. The arc movement problem of the first push plate can be solved by using an elastic component, and the cost is low. The detection device 400 will record the on-off performance of the air switch 100, and then the second driving component 300 drives the second toggle component 3 to push the air switch 100. The air switch 100 rotates downward along the arc surface under the action of its internal spring, so that the air switch 100 is in a disconnected state. The detection device 400 records the on-off performance of the air switch 100 again, completing a complete test, and then repeating the test in a cycle; compared with the existing structure, the air switch 100 detection device provided by the present invention is simple and stable, and has a low cost. During the test, the test efficiency is improved by driving the first driving component 200 and the second driving component 300.

It should be noted that the elastic component 12 can be a spring piece of other shapes, as long as it can have elastic force along the first direction X and the second direction Y. When the elastic component 12 has elastic force along the first direction X and the second direction Y, the elastic component 12 can prevent the end of the connected first push plate 11 close to the air switch 100 from being stuck on the arc surface of the air switch 100.

[0060] As a preferred embodiment of the present invention, in order to make the air switch 100 close more smoothly when the first push plate 11 pushes it to close, one end of the first push plate 11 away from the elastic member 12 is a circular arc surface, and the circular arc surface faces the air switch 100. Specifically, both the air switch 100 and the first push plate 11 are arc surfaces, and the arc surfaces are in point contact with the minimum friction force.
