[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] Please see Figures 1-4 The system includes a base 1, which is made of cast iron to ensure overall structural stability. A top plate 4 is fixedly mounted on top of the base 1 via four support columns 3. The support columns 3 are made of high-strength alloy steel to enhance the structural load-bearing capacity. A hydraulic cylinder 5 is bolted to the upper surface of the top plate 4. The extended end of the hydraulic cylinder 5 penetrates the top plate 4 and is fixedly mounted with a lifting plate 7 via a flange. A pressure detection head 9 is connected to the lower surface of the lifting plate 7. The pressure detection head 9 has a built-in pressure sensor that can provide real-time pressure feedback.

[0023] A clamping mechanism 2 is mounted on the upper surface of the base 1 for fixing the glass cover of the mobile phone to be tested. The clamping mechanism 2 includes a lateral adjustment component 22 that is slidably disposed on the base 1, and two double-sided clamping components 23 are symmetrically disposed above the lateral adjustment component 22.

[0024] The lateral adjustment assembly 22 includes a lower plate 221. A bidirectional screw 223 is rotatably connected to the middle of the lower plate 221 via a bearing. The two ends of the bidirectional screw 223 have opposite thread directions, and an adjustment handwheel is provided at one end extending outside the lower plate 221. The double-sided clamping assembly 23 includes two movable plates 231. The two movable plates 231 are slidably connected to both sides of the lower plate 221 via sliders, and both are threadedly engaged with the bidirectional screw 223. Rotating the bidirectional screw 223 can drive the two movable plates 231 to move relative to or away from each other along the lower plate 221, thereby achieving lateral spacing adjustment.

[0025] The upper end face of the movable plate 231 is rotatably connected to a double-acting screw 232 via a bearing. The two outer ends of the double-acting screw 232 have opposite thread directions and are each sleeved with a clamping seat 233 that is slidably connected to the upper end face of the movable plate 231. Rotating the double-acting screw 232 can drive the two clamping seats 233 to move relative to each other, thereby achieving longitudinal clamping of the glass cover.

[0026] The clamping mechanism 2 also includes two slide rails 21, which are fixed to the upper end face of the base 1 by bolts. The lower end face of the lower plate 221 is slidably connected to the slide rails 21 by a slider. A pull rod 222 is welded to the middle of the lower end face of the lower plate 221. By pulling the pull rod 222, the horizontal adjustment component 22 can be moved back and forth along the slide rail 21, which facilitates the picking and putting of the glass cover.

[0027] A magnetic block 25 is fixed to the rear side of the lower end face of the lower plate 221 by screws. The magnetic block 25 and the magnetic block 1 24 fixed to the rear side of the upper end face of the base 1 are magnetically attracted to each other. When the horizontal adjustment component 22 moves to the test position, the magnetic block 1 24 and the magnetic block 25 are attracted and fixed to each other to prevent displacement during the test.

[0028] The upper surface of each of the multiple clamping bases 233 is provided with a groove, and a silicone pad is pasted in the groove to prevent scratching the surface of the glass cover during clamping. The groove size is also compatible with common mobile phone glass covers, improving placement stability.

[0029] A protective plate 8 is detachably installed on the lower side of the lower end face of the lifting plate 7 by screws. The protective plate 8 is made of transparent acrylic sheet, which can not affect the observation of the test process, and can effectively block the flying fragments when the glass breaks.

[0030] Telescopic sleeves 6 are fixedly fitted at the four corners of the lifting plate 7. The telescopic sleeves 6 include an inner tube and an outer tube that are slidably fitted. The top end of the outer tube is welded and fixed to the lifting plate 7, and the bottom end of the inner tube is bolted to the base 1. The telescopic sleeves 6 guide the lifting movement of the lifting plate 7 to ensure that the pressure detection head 9 applies vertical pressure to the center of the glass cover.

[0031] The working principle and usage process of this utility model are as follows: According to the size of the glass cover of the mobile phone to be tested, rotate the adjusting handwheel of the bidirectional screw 223 to match the distance between the two movable plates 231 with the length of the cover; rotate the bidirectional lead screw 232 to adjust the distance between the two clamping seats 233 on the same movable plate 231 to match the width of the cover; pull the horizontal adjustment component 22 along the slide rail 21 to the front end through the pull rod 222 to facilitate the placement of the cover.

[0032] Place the mobile phone glass cover plate stably in the groove of the clamping seat 233, and finely adjust the bidirectional lead screw 232 again so that the clamping seat 233 gently clamps the cover plate; push the pull rod 222 to push the lateral adjustment component 22 to the test position so that the magnetic block 1 24 and the magnetic block 2 25 are attracted and fixed; fasten the protective plate 8, start the hydraulic cylinder 5, control the lifting plate 7 to slowly descend, the pressure detection head 9 contacts the cover plate and gradually applies pressure, observe the reading of the pressure detection head 9 in real time until the cover plate cracks, and record the maximum pressure value.
