[0020] In order to further understand the inventive content, features and effects of the present utility model, the following embodiments are hereby exemplified and described in detail in conjunction with the accompanying drawings.
[0021] The following will describe the structure of the present utility model in detail with reference to the accompanying drawings.
[0022] As Figures 1 to 4 shown, the electronic device drop test device provided by the embodiment of the present utility model includes a main body 1, a protection plate 2, a connection block 3 and a connection structure 4. The main body 1 includes a base 101. A drop slot 102 is opened at the top of the base 101. A support arm 103 is fixedly connected to the top of the base 101. A clamping arm 104 is arranged on the front surface of the support arm 103. The left and right sides of the top of the base 101 are respectively rotatably connected to the protection plate 2 through a rotating shaft. A connection slot 201 is opened on the left side of the front surface of the right protection plate 2. A connection block 3 is fixedly connected to the front surface of the left protection plate 2. A connection structure 4 is arranged inside the connection block 3.
[0023] Referring to Figure 3 and Figure 4 , the connection block 3 is fixedly connected to the front surface of the left protection plate 2. A moving sleeve 5 is fixedly connected to the front surface of the connection block 3. Moving rods 6 are fixedly connected to the upper and lower sides of the inner wall of the connection block 3. A moving slot 7 is opened on the right side of the connection block 3.
[0024] With the above solution: By setting the connection block 3, the connection block 3 and the connection structure 4 can cooperate to dock and fix the two protection plates 2 through the connection slot 201, preventing parts from flying everywhere during the test.
[0025] Referring to Figure 3 and Figure 4 , the connection structure 4 includes a linkage rod 8. The linkage rod 8 is arranged on the front surface of the connection block 3. The rear side of the linkage rod 8 extends and penetrates through the inner wall of the connection block 3. The outer surface of the linkage rod 8 is slidably connected to the inner wall of the moving sleeve 5. A linkage block 9 is fixedly connected to the rear side of the linkage rod 8.
[0026] With the above solution: By setting the linkage rod 8, when the linkage rod 8 is pulled, the linkage rod 8 can slide on the inner wall of the moving sleeve 5, thereby driving the movement of the linkage block 9.
[0027] Referring to Figure 4 , the linkage block 9 is fixedly connected to the rear side of the linkage rod 8. Positioning rods 10 are respectively fixedly connected to the upper and lower sides of the back surface of the linkage block 9. Linkage arms 11 are respectively arranged on the sides of the two positioning rods 10 away from each other.
[0028] With the above solution: By setting the linkage block 9, when the linkage block 9 moves, it can drive the two positioning rods 10 to move simultaneously, thereby driving the rotation of the two linkage arms 11 respectively.
[0029] Referring to Figure 4, in the middle of the two linkage arms 11 are rotatably connected to the inner wall of the connecting block 3 through a rotating shaft. The surfaces of the two sides of the two linkage arms 11 close to each other are respectively attached to the surfaces of the two sides of the two positioning rods 10 far from each other. Linkage grooves 12 are respectively formed on the right sides of the two linkage arms 11, and sliding rods 13 are respectively sleeved on the inner walls of the two linkage grooves 12.
[0030] Adopting the above scheme: By arranging the linkage arms 11, when the two positioning rods 10 move, they respectively squeeze the surfaces of the two linkage arms 11 to drive the linkage arms 11 to rotate. In this way, during the rotation of the two linkage arms 11, they can squeeze the two sliding rods 13 to move through the linkage grooves 12.
[0031] Reference Figure 4 , the outer surfaces of the two sliding rods 13 are respectively attached to the inner walls of the two linkage grooves 12. Slide blocks 14 are respectively fixedly connected to the rear sides of the two sliding rods 13. The inner walls of the two slide blocks 14 are respectively slidably connected to the surfaces of the sliding rods 13. Fixed springs 15 are fixedly connected to the sides of the two slide blocks 14 close to each other. The fixed springs 15 are sleeved on the surface of the moving rod 6. Fixed arms 16 are respectively fixedly connected to the right sides of the two slide blocks 14.
[0032] Adopting the above scheme: By arranging the sliding rods 13 and the slide blocks 14, when the two sliding rods 13 move, they drive the slide blocks 14 to slide close to each other on the surface of the moving rod 6, and at the same time squeeze the fixed springs 15 to compress, thereby driving the two fixed arms 16 to move close to each other.
[0033] Reference Figure 4 , the outer surfaces of the two fixed arms 16 are respectively slidably connected to the inner walls of the moving grooves 7, and the two fixed arms 16 are respectively inserted into the inner walls of the connecting grooves 201.
[0034] Adopting the above scheme: By arranging the fixed arms 16, the two fixed arms 16 can slide close to each other on the surface of the moving groove 7, so that they can be separated from the connecting groove 201 and release the fixed limit on the right protective plate 2.
[0035] The working principle of the present utility model:
[0036] During use, rotate and then erect the two protective plates 2 respectively, and then pull the linkage rod 8 to make it slide inside the inner wall of the moving sleeve 5. The linkage rod 8 drives the linkage block 9 to move leftward, so that the linkage block 9 drives the two positioning rods 10 to move simultaneously. During the movement of the two positioning rods 10, they respectively squeeze the surfaces of the two linkage arms 11, driving the rotation of the two linkage arms 11. The two linkage arms 11 respectively squeeze the two sliding rods 13 through the linkage grooves 12 to make them move. The two sliding rods 13 drive the two sliding blocks 14 to slide on the surface of the moving rod 6 simultaneously, and at the same time squeeze the compression of the fixed spring 15. The two sliding blocks 14 then drive the two fixed arms 16 to slide close on the surface of the moving groove 7 respectively. Subsequently, dock the right protective plate 2 with the left protective plate 2, so that the two fixed arms 16 are inserted into the connection groove 201. Then release the linkage rod 8 to reset the fixed spring 15 and push the two sliding blocks 14 to move away, and drive the movement of the two fixed arms 16 away, so that the fixed arms 16 are tightly attached to the inner wall of the connection groove 201, completing the docking and fixing of the two protective plates 2. Then, clamp and fix the electronic device to be tested through the clamping arm 104 and conduct a drop test.
[0037] In summary, for this electronic device drop test device, through the cooperative work of the main body 1, the protective plate 2, the connection block 3 and the connection structure 4, it solves the problem that when the test device conducts a drop test, due to the large impact force generated when dropping from a high place, this impact force may cause parts in the electronic device to break, fall off or pop out, and the parts flying out may cause damage to other devices or personnel.
