They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0020] The specific embodiment of this utility model: The glass cover impact testing device includes a bracket, which is formed by a fixed plate 5 and a base plate 1 arranged in parallel and connected by a support column 12. The base plate 1 has a test groove for loading a glass cover plate on its upper surface, and an impact rod 3 that moves vertically is arranged above the test groove. The impact rod 3 passes through the fixed plate 5. The end of the impact rod 3 is provided with a power structure for driving the impact rod 3 to move vertically.

[0021] The power structure includes a sleeve 7 fitted around the outside of the impact rod 3 and fixed to the fixing plate 5. A spring 8 and a stop bar 9 are provided between the sleeve 7 and the impact rod 3. The side wall of the sleeve 7 has a slot 6 that is slidably connected to the stop bar 9.

[0022] An adjusting nut 13 is fitted on the outside of the impact rod 3 located below the fixed plate 5 to adjust the degree of compression of the impact rod 3 on the spring 8. A hook structure for locking and releasing the adjusting nut 13 is provided on the outside of the adjusting nut 13.

[0023] Furthermore, the hook structure includes an elastic hook 4, which is L-shaped to support and hook the adjusting nut 13, and the lower end face of the elastic hook 4 is provided with a wedge-shaped surface that changes the opening angle of the elastic hook 4 by being squeezed by the adjusting nut 13.

[0024] Furthermore, the adjusting nut 13 is threadedly connected to the impact rod 3.

[0025] Furthermore, the hook structure also includes a release component for changing the opening angle of the elastic hook 4.

[0026] Furthermore, the release assembly includes a pressure plate 11, the middle of which is hinged to the fixed plate 5, and the other end is connected to a traction rope 10, which is connected to the elastic hook 4 via a steering wheel.

[0027] Furthermore, a protective shell 2 is also provided on the outside of the test tank.

[0028] Furthermore, a scale is provided on the outer side of the impact rod 3.

[0029] It should be noted that this utility model is a glass cover impact testing device. In specific operation,

[0030] 1. The operator presses the pressure plate 11 of the release component with both hands at the same time. The pressure plate 11 is hinged to the fixed plate 5 in the middle. Pulling the traction rope 10 will pull the elastic hook 4, causing deformation and changing the opening angle of the elastic hook 4. At this time, the impact rod 3 is released under the action of the spring 8. The resulting impact force acts on the glass cover plate to test the impact resistance of the glass cover plate.

[0031] As a supplement, the side wall of the sleeve 7 is provided with a slot 6 that is slidably connected to the stop bar 9. The stop bar 9 is slidably connected to the slot 6, and the slot 6 can realize the functions of guiding and limiting, so as to prevent the impact bar 3 from falling off.

[0032] 2. After the test, the tester pushes the impact rod 3 upward. The lower end face of the elastic hook 4 is provided with a wedge-shaped surface that changes the opening angle of the elastic hook 4 by pressing with the adjusting nut 13. The adjusting nut 13 of the impact rod 3 causes the elastic hook 4 to deform, and finally the adjusting nut 13 is supported and hooked by the elastic hook 4.

[0033] 3. By rotating the adjusting nut 13, the impact rod 3 can move upward or downward under the limiting action of the thread and the stop rod 9, thereby changing the compression of the spring. Marks are made on the scale of the impact rod 3 to achieve testing of different impact forces.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
