[0002] Tempered glass is a kind of glass with compressive stress on the surface. It is a safety glass. When it is subjected to external force, it first offsets the surface stress, thereby improving the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc. It has good thermal stability and can withstand a temperature difference that is three times that of ordinary glass. It is widely used in various doors and windows, automobiles, curtain walls, and window furniture. Since tempered glass is mostly used in occasions with certain safety requirements, its strength needs to be tested after processing to ensure quality.

[0003] When conducting strength testing on existing tempered glass, state simulation is required. During the simulation, the impact force and direction of the tempered glass need to be considered. However, most strength detection devices in the prior art can only detect the feedback from the tempered glass when pressed, and cannot meet multiple detection states, resulting in incomplete detection parameters and poor safety.

[0006] Preferably, the two fixed side frames are both arranged in a horizontally placed "U" shape, and adjustment grooves are symmetrically opened on the top surface of the detection table at the bottom of the fixed side frame. A movable screw is symmetrically slidably connected inside each of the adjustment grooves, and a fixed clamp is threadedly sleeved on one end of the movable screw extending to the lower part of the adjustment groove.

[0007] Preferably, an air inlet window flush with the top surface of the testing platform is embedded in the top surface of the testing platform between the two fixed side frames, and an inner panel is fixed inside the testing platform below the air inlet window, a fan is arranged inside the inner panel, and an air outlet window is opened on the bottom surface of the testing platform below the inner panel.

[0008] Preferably, the support arm is configured as an inverted "L" shape that cooperates with the detection platform, and a movable groove that cooperates with the support arm is provided on the top surface of the detection platform.

[0009] Preferably, air-permeable filters are fixed inside the air inlet window and the air outlet window, the height of the inner enclosure is greater than the height of the fan, and the upper and lower ends of the inner enclosure are respectively fixed on the upper and lower inner walls of the detection platform.

[0010] Preferably, the length of each of the fixed clamping block and the fixed side frame is greater than the length of the adjustment slot, and each of the movable screw rods is configured as an inverted "T" shape.

[0011] Compared with the prior art, the advantages and positive effects of the utility model are:

[0012] 1.

[0013] 2. In the utility model, tempered glass of different lengths can be fixed and tested through adjustable fixed side frames, which improves the application range of the detection device. In addition, the internal negative pressure component forms a negative pressure on the surface of the air inlet window when the fan is running during the detection, so that the tempered glass can be adsorbed on the surface of the air inlet window after being broken, avoiding splashing after the tempered glass breaks, and can simulate wind force.
