It can be seen that the first rotating shaft 2 plays a supporting and fixing role for the plurality of torsion springs 20, and when the flip cover assembly 3 is no longer limited, the torsion springs 20 play a role of resetting and springing the flip cover assembly 3, thereby reducing unnecessary operation steps and improving the test efficiency.

[0017] like Figure 4 As shown, in this embodiment, the pressing assembly 4 also includes a pressing block 41, a pair of guide columns 42, a pair of linear bearings 43, a driving block 44, a pressing block 45 and a plurality of test probes. The pressing block 41 is connected and matched with the driving block 44 through a pair of guide columns 42. The linear bearing 43 is arranged on the driving block 44. The guide column 42 and the linear bearing 43 are slidably matched. The upper and lower ends of the driving block 44 are floatingly matched with the flip cover assembly 3 and the pressing block 45 through a first floating assembly 46 and a second floating assembly 47 respectively. A plurality of the test probes are fixedly matched on the pressing block 45, and the test probes are matched with product components. It can be seen that the guide column 42 serves to connect the pressing block 41 and the driving block 44, the linear bearing 43 serves to guide and limit the guide column 42, the first floating component 46 serves to allow the driving block 44 to float and cooperate with the flip cover component 3, and the second floating component 47 serves to allow the pressing block 45 to float and cooperate with the driving block 44. The driving block 44 serves to press down the pressing block 45 so that the pressing block 45 pushes the test probe to contact and cooperate with the product component, and the pressing block 45 serves to support and fix several of the test probes.

[0018] like Figure 3As shown, in this embodiment, the downward-pressing linked self-locking component 5 includes a V-shaped block 50, a strip block 51, a first spring 52, a top column 53 and a cover plate 54.

The cover plate 54 is limited and matched on the flip cover component 3, and the cover plate 54 is limited and matched with the left end of the strip block 51. The first spring 52 is used to support and reset the strip block 51. At the same time, the first spring 52 can also absorb excessive pressure and buffer the pressure, thereby protecting the V-shaped block 50 and the strip block 51. The cover plate 54 protects the V-shaped block 50, the strip block 51, the first spring 52 and the cover plate 54. At the same time, the cover plate 54 also serves as a sliding limit for the strip block 51.

The second equal-height screw connects the drive block 44 and the downward pressure block 45, and also serves as an up and down floating guide for the second spring. The second spring allows the downward pressure block 45 to float and fit in the drive block 44. At the same time, the second spring can also absorb excessive downward pressure to prevent other components from being damaged due to excessive pressure.

[0021] like Figure 3 and Figure 5As shown, in this embodiment, the rotating ends of a pair of small buckles 40 are rotatably engaged with the pressing assembly 4 through the second rotating shaft 41, and the limiting ends of the small buckles 40 are limitedly engaged with the flip assembly 3. It can be seen that the second rotating shaft 41 plays a role of flipping support for the small buckles 40, and the small buckles 40 play a role of limiting the pressing assembly 4 with the flip assembly 3.

[0022] like Figure 3 As shown, in this embodiment, the middle part of the large buckle 30 is rotatably matched with the flip cover assembly 3 through the third rotating shaft 31, the limiting end of the large buckle 30 is linked with the flip cover assembly 3, the pressing end of the large buckle 30 is limited with the push block 60, and a third spring 32 is arranged between the pressing end of the large buckle 30 and the flip cover assembly 3, and the third spring 32 is respectively limited with the pressing end of the large buckle 30 and the flip cover base 1. It can be seen that the third rotating shaft 31 plays a role of flipping support for the large buckle 30, the large buckle 30 plays a role of limiting the flip cover assembly 3 with the flip cover base 1, the pressing end of the large buckle 30 cooperates with the push block 60, and when the pressing end of the large buckle 30 is pressed, the pressing end of the large buckle 30 plays a role of linkage cooperation with the push block 60, and the third spring 32 plays a role of supporting and resetting the pressing end of the large buckle 30.

[0023] In this embodiment, the working principle of the present invention is as follows: like Figures 1 to 5 As shown, in the normal state, the flip cover assembly 3 is as above Figure 2 At this time, the strip block 51 is pushed toward the direction close to the small buckle 40 by the action of the first spring 51, and the small buckles 40 on both sides are blocked by the strip block 51 and cannot be pressed down and buckled, thereby protecting the test probe of the flip base 1 and the test probe in the pressing component 4; After placing the product, the flip cover assembly 3 is closed. During the process of flip cover assembly 3, the V-shaped block 50 gradually touches the top column 53 on the flip cover base 1, and the V-shaped block 50 rotates clockwise and pushes the bar block 51 away from the small buckle 40. At the same time, the large buckle 30 is buckled with the flip cover base 1, and the pressing assembly 4 can be pressed down to prevent the flip cover assembly 3 from pressing down and damaging the probe before it is covered in place. After the test is completed, the pressing end of the large buckle 30 is pressed to make the large buckle 30 rotate counterclockwise, overcome the elastic force of the third spring 22 and drive the push block 40 to move toward the small buckle 40, and the unlocking protrusion on the push block 40 pushes the small buckles 40 on both sides to both sides, thereby releasing the small buckles 40 on both sides, and then realizing the linkage action. Then, the flip cover assembly 3 automatically pops open under the action of several torsion springs 20 to complete the test.

[0024] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
