[0002] With the rapid development of science and technology, the technology beauty industry has emerged as a new industry, and the popularity of smart phones has driven the development of the fashion IT industry. In response to the increase in mobile phone brands and functions, mobile phone protective cases are diversified. According to the texture, there are PC cases, leather, silicone, cloth, hard plastic, leather cases, metal tempered glass cases, soft plastic, velvet, silk and other categories. Mobile phone protective cases not only make your mobile phone a landscape as a decoration, but also protect the mobile phone from falling, scratching, waterproof and shockproof! The wear resistance of mobile phone cases is an important indicator for testing the quality of mobile phone cases. Therefore, mobile phone cases need to be tested for wear resistance before leaving the factory. The usual testing method is that workers use sandpaper to polish the mobile phone cases, which is very inefficient. Usually, the number of samples taken is large, and relying on manual methods will significantly increase the labor intensity.

[0003] A Chinese patent discloses a mobile phone case wear resistance detection device (authorization announcement number CN206990378U).

[0026] Reference Figure 1-Figure 3As shown, the utility model provides a technical solution: a mobile phone shell wear resistance detection device, including a base 1, a first support block 2 is installed at the front end of the top of the base 1, an extension block 3 is installed at the rear end of the first support block 2, a mounting groove 4 is opened at the rear end of the extension block 3, a mounting block 5 is slidably connected inside the mounting groove 4, a positioning frame 6 is fixedly connected to the rear end of the mounting block 5, second support blocks 7 are installed on both sides of the top of the base 1, a rotating wheel 8 is rotatably connected to the opposite surface of the second support block 7, a friction belt 9 is installed on the surface of the rotating wheel 8, a shell 10 is fixedly connected to both sides of the extension block 3, a fixing block 11 is fixedly connected to both sides of the mounting block 5, and the fixing block 11 The top and bottom of the housing 10 are provided with fixing grooves 12, and a clamping block 13 is inserted into the fixing groove 12. The sides of the clamping blocks 13 that are away from each other are fixedly connected to the connecting blocks 14, and the facing surfaces of the connecting blocks 14 are fixedly connected to the first trapezoidal blocks 15. The first trapezoidal blocks 15 are located at the front end of the connecting blocks 14. A second trapezoidal block 16 is arranged inside the housing 10, and a control rod 17 is fixedly connected to the front end of the second trapezoidal block 16. The top and bottom of the inner cavity of the housing 10 are fixedly connected to the limiting spring 18, and the end of the limiting spring 18 close to the connecting block 14 is fixedly connected to the connecting block 14, and the second trapezoidal block 16 is driven to the first trapezoidal block by pushing the control rod 17 backward. 15 is squeezed, so that the first trapezoidal block 15 drives the connecting block 14 to move to the side away from the second trapezoidal block 16, so that the connecting block 14 drives the clamping block 13 to disengage from the inner diameter of the fixing groove 12, and the limit of the fixing block 11 is released, so that the user can take out the positioning frame 6 at the rear end of the extension block 3 and replace the positioning frame 6. After selecting the positioning frame 6 of the appropriate size, by inserting the mounting block 5 into the mounting groove 4 at the rear end of the extension block 3, the fixing block 11 is inserted into the interior of the housing 10. When the fixing block 11 is inserted into the interior of the housing 10, the rear end of the fixing block 11 squeezes the clamping block 13, so that the clamping blocks 13 move away from each other. The limit spring 18 is moved to one side and the limit spring 18 is charged. When the positioning frame 6 completely enters the interior of the installation groove 4, the clamping block 13 is aligned with the fixing groove 12 on the surface of the fixing block 11. The rebound force released by the limit spring 18 drives the connecting block 14 to insert the clamping block 13 into the interior of the fixing groove 12, thereby fixing the fixing block 11 and preventing the positioning frame 6 from being separated from the rear end of the extension block 3. Through the arrangement of the above structure, the user can quickly replace the positioning frame 6 according to the specifications of the mobile phone case, thereby improving the overall detection range of the equipment, and selecting the specifications that match the mobile phone case can effectively prevent the mobile phone case from falling off during the test.

[0027] Reference Figure 3As shown, in this embodiment: a tension spring 19 is sleeved on the surface of the control rod 17, and the rear end of the tension spring 19 is fixedly connected to the front end of the second trapezoidal block 16, and the rear end of the tension spring 19 is fixedly connected to the front end of the inner cavity of the shell 10. When the clamping block 13 is inserted into the inner diameter of the fixing groove 12, the tension force generated by the tension spring 19 causes the second trapezoidal block 16 to move away from the first trapezoidal block 15, preventing the second trapezoidal block 16 from squeezing the first trapezoidal block 15, causing the clamping block 13 to detach from the inner diameter of the fixing groove 12.

[0028] Reference Figure 3 As shown, in this embodiment: a slide rod 20 is fixedly connected to the inside of the shell 10, and a through hole 21 is opened on the surface of the connecting block 14 for use with the slide rod 20. Through the sliding connection between the slide rod 20 and the through hole 21, an auxiliary guiding effect is played on the movement of the connecting block 14, preventing the connecting block 14 from tilting up when the second trapezoidal block 16 squeezes the first trapezoidal block 15.

[0029] Reference Figure 3 As shown, in this embodiment: both sides of the second trapezoidal block 16 are fixedly connected with the first slider 22, and both sides of the inner cavity of the shell 10 are provided with a first slide groove 23 used in conjunction with the first slider 22. When the second trapezoidal block 16 is moving, the sliding connection between the first slider 22 and the first slide groove 23 plays an auxiliary limiting role in the movement of the second trapezoidal block 16, thereby preventing the second trapezoidal block 16 from being offset when moving.

[0030] Reference Figure 4 and Figure 5 As shown, in this embodiment: the top and bottom of the mounting groove 4 are fixedly connected with the second slider 24, and the top and bottom of the mounting block 5 are provided with a second slide groove 25 used in conjunction with the second slider 24. When the mounting block 5 is inserted into the interior of the mounting groove 4, the second slider 24 is slidably connected to the inner diameter of the second slide groove 25, which guides and limits the mounting block 5. When the mounting block 5 completely enters the interior of the mounting groove 4, it limits the mounting block 5 to prevent the mounting block 5 from being offset.

[0031] Reference Figure 6 and Figure 7As shown, in the present embodiment: the facing surfaces of the second support block 7 are fixedly connected with a scraper 26, a dust box 27 is arranged at the bottom of the friction belt 9, a handle 28 is fixedly connected to the rear end of the dust box 27, the facing surfaces of the second support block 7 are fixedly connected with a first guide block 29, and the two sides of the dust box 27 are fixedly connected with a second guide block 30, and a sliding groove 37 used in conjunction with the first guide block 29 is provided on the side of the second guide block 30 close to the first guide block 29. When the friction belt 9 rubs the mobile phone case, there are fine particles attached to the surface of the friction belt 9. The scraper 26 is provided to scrape off the fine particles on the surface of the friction belt 9, and the sliding groove 37 used in conjunction with the first guide block 29 is provided on the surface of the second guide block 30 to facilitate the user to install the dust box 27.

[0032] Reference Figure 7 As shown, in this embodiment: a spring groove 31 is provided on the top of the first guide block 29, an insert block 32 is slidably connected inside the spring groove 31, and a fixing spring 33 is fixedly connected to the bottom of the insert block 32; a socket 34 used in conjunction with the insert block 32 is provided on the top of the second guide block 30; when the dust box 27 is installed to a suitable position through the sliding connection with the first guide block 29 through the sliding groove 37, the elastic force generated by the fixing spring 33 drives the insert block 32 to move upward, so that the insert block 32 is inserted into the inner diameter of the socket 34, so that the position of the dust box 27 is fixed, and displacement of the dust box 27 is prevented.

[0033] Reference Figure 7 As shown, in this embodiment: the front end and the rear end of the plug block 32 are fixedly connected with the third slider 35, and the front end and the rear end of the inner cavity of the spring groove 31 are provided with a third slide groove 36 used in conjunction with the third slider 35. When the fixed spring 33 drives the plug block 32 to move upward, the third slider 35 and the third slide groove 36 are used in conjunction to limit the movement of the plug block 32, thereby preventing the plug block 32 from disengaging from the inner diameter of the spring groove 31.

[0034] The utility model works as follows: the user pushes the control rod 17 backward to drive the second trapezoidal block 16 to squeeze the first trapezoidal block 15, so that the first trapezoidal block 15 drives the connecting block 14 to move to the side away from the second trapezoidal block 16, so that the connecting block 14 drives the clamping block 13 to disengage from the inner diameter of the fixing groove 12, and releases the limit of the fixing block 11, so that the user can take out the positioning frame 6 at the rear end of the extension block 3 and replace the positioning frame 6. After selecting the positioning frame 6 of the appropriate size, by inserting the mounting block 5 into the mounting groove 4 at the rear end of the extension block 3, the fixing block 11 is inserted into the interior of the shell 10. When the fixing block 11 is inserted into the interior of the shell 10, the rear end of the fixing block 11 squeezes the clamping block 13, so that the clamping block 13 moves to the side away from each other, and the limit spring 18 accumulates force. When the positioning frame 6 completely enters the interior of the mounting groove 4, the clamping block 13 is aligned with the fixing groove 12 on the surface of the fixing block 11. The rebound force released by the limit spring 18 drives the connecting block 14 to insert the clamping block 13 into the interior of the fixing groove 12, thereby fixing the fixing block 11 and preventing the positioning frame 6 from being separated from the rear end of the extension block 3. The sliding connection between the slide rod 20 and the through hole 21 plays an auxiliary guiding role in the movement of the connecting block 14, preventing the second trapezoidal block 16 from tilting when the first trapezoidal block 15 is squeezed. When the clamping block 13 is inserted into the inner diameter of the fixing groove 12, the tension generated by the tension spring 19 causes the second trapezoidal block 16 to move away from the first trapezoidal block 15, preventing the second trapezoidal block 16 from squeezing the first trapezoidal block 15, causing the clamping block 13 to be separated from the inner diameter of the fixing groove 12. Through the arrangement of the above structure, the user can quickly replace the positioning frame 6 according to the specifications of the mobile phone case, thereby improving the overall detection range of the equipment, and selecting the specifications that match the mobile phone case can effectively prevent the mobile phone case from falling off during the test.
