Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figs. 1-3 This utility model provides a technical solution: a notebook shell strength testing device, including a base plate 1, a frame 5 vertically installed on the top of the base plate 1, a lifting plate 7 arranged inside the frame 5, a lifting component arranged on the top of the lifting plate 7, a testing component arranged on the bottom of the lifting plate 7, and an adsorption fixing component arranged on the base plate 1.

[0028] The adsorption and fixation assembly includes an oral cavity 2, an adsorption plate 3, a negative pressure unit 4, and an air inlet 12. The oral cavity 2 is opened in the base plate 1, and multiple adsorption plates 3 are connected to the top of the oral cavity 2. The negative pressure unit 4 is installed at the bottom of the base plate 1, and the air inlet 12 is installed at the bottom of the oral cavity 2. The air inlet 12 is connected to the negative pressure unit 4 through a pipe.

[0029] Specifically, after placing the workpiece on top of the adsorption plate 3, the negative pressure machine 4 is started to draw air from the air inlet 12. The air inlet 12 is drawn away from the oral cavity 2, and the negative pressure generated in the oral cavity 2 can generate negative pressure on the adsorption plate 3, thereby adsorbing and fixing the workpiece.

[0030] Furthermore, multiple support blocks 13 are installed on the top of the base plate 1, and the support blocks 13 and the suction cup 3 are arranged alternately in sequence;

[0031] Specifically, the support block 13 can support the bottom of the workpiece, preventing the workpiece from shaking under pressure.

[0032] Furthermore, the lifting assembly includes an electric push rod 6, which is vertically installed at the top of the base plate 1, and the output end of the electric push rod 6 is connected to the top of the lifting plate 7.

[0033] Specifically, the electric push rod 6 drives the lifting plate 7 to move up and down, and the lifting plate 7 can drive the hardness tester 9 to move up and down, which can ensure the inspection of the workpiece.

[0034] Furthermore, the testing component includes an electric slide bar 8 and a hardness tester 9. The electric slide bar 8 is horizontally installed inside the lifting plate 7, and the hardness tester 9 is installed at the output end of the electric slide bar 8.

[0035] Specifically, when multiple tests are required on the top of the workpiece, the electric slide bar 8 is activated to drive the hardness tester 9 to move laterally. The lateral movement of the hardness tester 9 enables multiple tests to be performed on the top of the workpiece.

[0036] Furthermore, guide grooves 10 are provided on both sides of the frame 5, and guide blocks 11 are slidably installed in the guide grooves 10. The guide blocks 11 are all connected to the outside of the lifting plate 7.

[0038] Furthermore, a display 14 is installed on the inner wall of frame 5;

[0039] Specifically, the detected data can be displayed on the monitor 14.

[0040] Working principle: When using this notebook casing strength testing device, after placing the workpiece on top of the adsorption plate 3, the negative pressure machine 4 is activated to draw air from the suction port 12. The air in the oral cavity 2 is drawn away through the suction port 12, and the negative pressure generated in the oral cavity 2 creates negative pressure on the adsorption plate 3. The adsorption plate 3 then adsorbs and fixes the workpiece. The electric push rod 6 drives the lifting plate 7 to move up and down, which in turn drives the hardness tester 9 to move up and down. The electric slide rod 8 is activated to move the hardness tester 9 laterally. The lateral movement of the hardness tester 9 allows for multiple tests on the top of the workpiece.
