[0002] Mobile phone, also known as mobile phone or wireless phone, is usually called mobile phone. It was originally just a communication tool. In the early days, it was also known as "big brother". It is a portable phone that can be used in a wide range.
[0003] The terminal was first developed from the battlefield mobile phone manufactured by Bell Labs in the United States in 1940. With the development of modern technology, smart phones have three major features: excellent operating system, free installation of various software, and full touch-screen operation. After the production of mobile phone displays, the mobile phone displays need to be tested for their anti-fall ability in order to test whether the mechanical properties of the mobile phone displays are qualified.
[0004] In real life, mobile phones may accidentally fall to the ground, but the materials of floors in different occasions are different, and the existing detection devices can generally only simulate the floor material of a single occasion for detection, resulting in large errors in the test results at the factory due to environmental factors, making the mechanical properties test results of the mobile phone display inaccurate.

The guide frame 2 is welded to the front side of the lower part of the first fixing frame 1, the second fixing frame 3 is connected to the inner side of the middle part of the first fixing frame 1 in a longitudinal sliding manner, the upper part of the second fixing frame 3 is interlaced and rotatably connected, the rear end of the rotating shaft 4 is welded with a knob 5, the end of the rotating shaft 4 away from the knob 5 is welded with a placement plate 6, and the second fixing frame 3 is connected to the inner side of the middle part of the second fixing frame 3. A U-shaped plate 7 is fixedly connected to the rear middle side of the fixed frame 3, and the U-shaped plate 7 is made of soft plastic material. A block 8 is welded on the rotating shaft 4, and the block 8 is located in the middle of the U-shaped plate 7. A clamping block 9 is rotatably connected to the right side of the rear of the second fixed frame 3. A plurality of clamping grooves for clamping the clamping block 9 are provided on one side of the first fixed frame 1. A first elastic member 10 is connected around the lower side of the clamping block 9 and the second fixed frame 3. The first elastic member 10 is a torsion spring, and a shifting block 11 is welded to the rear end of the clamping block 9. A simulation frame 12 is slidably connected to the inner side of the guide frame 2.
[0024] like Figure 1 , Figure 4 and Figure 5 As shown, it also includes a handle 13, a fixed block 14, a buckle 15 and a clamping block 16. The handle 13 is welded on the front side of the simulation frame 12, the fixed block 14 is welded on the front side of the guide frame 2, and the clamping block 16 is welded on the front side of the simulation frame 12. The clamping block 16 is adjacent to the fixed block 14. The fixed block 14 is rotatably connected with the buckle 15. The buckle 15 is made of plastic material and has a certain toughness. The buckle 15 can be rotated downward to clamp with the clamping block 16.
[0025] like Figure 6As shown, it also includes a clamping block 17, a clamping plate 18, a second elastic member 19 and a pull ring 20. The clamping plate 18 is slidably connected to the left side of the placement plate 6, and the clamping block 17 is welded to the right side of the placement plate 6. A second elastic member 19 is sleeved between the clamping plate 18 and the placement plate 6. The second elastic member 19 is a return spring. A pull ring 20 is fixedly connected to the left side of the clamping plate 18, and the clamping plate 18 can be pulled to one side to clamp the mobile phone together with the clamping block 17.
[0026] like Figure 1 and Figure 7 As shown, it also includes a protective cover 21, a guide rod 22, a movable plate 23 and a push rod 24. The protective cover 21 is clamped on the uppermost end of the guide frame 2, and the protective cover 21 is in the shape of a mouth with an opening facing upward. A guide rod 22 is provided on the front side of the lower part of the protective cover 21, and the guide rod 22 is parallel to the ground. Two symmetrical movable plates 23 are slidably connected to the guide rod 22, and the two symmetrical movable plates 23 can be moved to the left and right sides along the guide rod 22 to separate them, thereby facilitating the removal of the mobile phone. A push rod 24 is fixed to the movable plate 23.
[0027] When the inspector needs to test the anti-fall ability of the mobile phone display, the device can be used. First, place the device horizontally, turn the buckle 15 upward, so that the buckle 15 no longer jams the clamping block 16, and then pull the handle 13 to the front side to take out the simulation frame 12, and then put the material simulating the ground (such as sand and stone, etc.) into the simulation frame 12, and then reset the simulation frame 12, and jam the buckle 15 into the clamping block 16.
[0028] When the inspector needs to adjust the inspection height, he first rotates the shift block 11 counterclockwise to disengage the clamping block 9 from the clamping slot, adjusts the inspection height to be adjusted, and then re-inserts the clamping block 9 into the clamping slot to complete the height adjustment.
[0029] When the inspector needs to conduct an anti-fall test, he first pulls the pull ring 20 to the left, and the pull ring 20 drives the clamping plate 18 to move to the left together. At this time, the second elastic member 19 is compressed, and the range of the mobile phone clamped between the clamping plate 18 and the clamping block 17 is increased. Then, the mobile phone display is placed on the placement plate 6 with the front side facing up, and then the pull ring 20 is released. The second elastic member 19 drives the clamping plate 18 to reset and clamp the mobile phone, and then the knob 5 is turned 180° counterclockwise. The knob 5 drives the shaft 4, the block 8 and the placement plate 6 to rotate 180° counterclockwise. During the process, the U-shaped plate 7 undergoes elastic deformation, and then the U-shaped plate 7 is reset and clamps the block 8, so that the block 8 will not rotate easily. At this time, the mobile phone display is facing downward, and then the pull ring 20 is pulled to the right so that the clamping plate 18 no longer clamps the mobile phone, and the mobile phone falls into the simulation frame 12 below. Finally, the push rod 24 is pushed to the left and right sides, and the push rod 24 drives the two movable plates 23 to move to the left and right sides to separate them. The mobile phone display can be taken out to check the damage situation and degree, and the height of the mobile phone display being damaged is recorded, so as to complete the detection of the anti-fall performance of the mobile phone display.
