[0004] As we all know, mobile phones face different environments in daily use. For example, the phone is placed on a table made of different materials or in a pocket, which causes friction in the phone case in different environments. The existing technology uses a single grinding block to test the phone case to determine the wear resistance of the phone case, which often cannot meet the diversity of the phone's usage environment. Whether the wear resistance of the phone case is qualified should be based on different usage environments. Therefore, we specifically designed a detection device that simulates the wear resistance of the phone case in different environments. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

A silicone sheet 3021 is fixed to the top of the side where the holding blocks 302 are close to each other. The silicone sheet 3021 can improve the stability of the mobile phone shell body 17 after being clamped, and at the same time avoid wear of the mobile phone shell body 17 when being clamped. A positioning seat 303 is also fixed to the center position of the top of the support platform 1; a servo motor 4 is also installed on the front of the bottom of the support platform 1. The power output shaft of the servo motor 4 movably penetrates the support platform 1 and is fixed with an eccentric wheel 5. The position of the eccentric wheel 5 corresponds to the center position of the front of the movable seat 301. When the eccentric wheel 5 rotates, it can cyclically contact the movable seat 301, thereby pushing the movable seat 301 to slide back and forth on the fixed seat 2, and utilizing the movement of the movable seat 301 to drive the mobile phone shell body 17 on the movable seat 301 to perform friction detection with multiple grinding blocks.

[0026] In this embodiment, three fixed frames 13 are arranged at the bottom of the push plate 9, and a locking rod 14 is threadedly connected to the front of each fixed frame 13, one end of the locking rod 14 passes through the interior of the fixed frame 13 and is rotatably connected to the extrusion plate 15, and a rubber gasket 16 is fixedly connected to the other side of the inner wall of the fixed frame 13. Grinding blocks are installed inside the three fixed frames 13, and the grinding blocks are respectively a paint plate, a solid wood plate and a plastic block, and the plastic block is covered with a pure cotton cloth cover.

[0027] Specifically, a locking rod 14 is provided on the side of the fixed frame 13. When the locking rod 14 is turned, the grinding block inside the fixed frame 13 can be squeezed and fixed or unlocked and removed, which can facilitate the replacement of the grinding block. The rubber gasket 16 inside the fixed frame 13 can increase the friction of the grinding block in the fixed frame 13, thereby improving the stability of the grinding block. Grinding blocks of different materials are installed in the three fixed frames 13 respectively, which can simulate the wear of the mobile phone shell body 17 when used in different environments. One detection can realize simulated detection of various situations, with higher detection efficiency and saving time and effort.

[0028] In this embodiment, a guide slider 3022 is fixedly connected to the bottom of the clamping block 302 and is slidably connected to the guide slot 304. Limit sliders 3023 are fixed on the front and rear sides of the guide slider 3022. Limit slots 3011 are provided on both sides of the inner wall of the guide slot 304, and the limit slider 3023 is slidably connected to the limit slot 3011; a double-threaded rod 10 is threadedly connected between the two guide sliders 3022, and the threads at both ends of the double-threaded rod 10 are opposite, and each section of the thread passes through a guide slider 3022, the double-threaded rod 10 is placed in the guide slot 304, and one end of the double-threaded rod 10 is rotatably connected to the inner wall of the guide slot 304, and the other end movably passes through the movable seat 301 and is fixed with a screw block.

[0029] Specifically, when the double-threaded rod 10 rotates, it can synchronously drive the two guide sliders 3022 to move towards or away from each other, thereby adjusting the distance between the two clamping blocks 302, which can facilitate the clamping and fixation of the mobile phone shell body 17. The limiting slider 3023 on the guide slider 3022 slides in the limiting groove 3011, which improves the stability of the guide slider 3022 when it moves in the guide groove 304, and ensures the stability of the clamping block 302 when it moves.

[0030] In this embodiment, the front of the movable seat 301 is designed to be an arc structure, and limiting slide bars 12 are fixed on both sides of the back of the movable seat 301. A reset spring 1201 is sleeved on the rod body of the limiting slide bar 12, and the end of the limiting slide bar 12 away from the movable seat 301 is movable and passes through the support plate 6, and one end of the reset spring 1201 is fixed on the movable seat 301, and the other end is fixed on the support plate 6; a limiting slide plate 11 is fixed to the bottom of the movable seat 301, and a guide groove is opened on the top of the fixed seat 2, the movable seat 301 is attached to the top of the fixed seat 2 and the limiting slide plate 11 is slidably connected in the guide groove.

[0031] Specifically, the front of the movable seat 301 is designed to be an arc structure, which can cooperate with the push of the eccentric wheel 5 to better perform sliding movements, and a limiting slide bar 12 is set on the back of the movable seat 301, which cooperates with the limiting slide plate 11 at the bottom of the movable seat 301 to limit and stabilize the movement trajectory of the movable seat 301, and can further ensure the stability of the movable seat 301 during movement. The setting of the reset spring 1201 can push the movable seat 301 back to the initial position through the rebound effect.

[0032] In this embodiment, a mobile phone housing body 17 is also included. The mobile phone housing body 17 is placed on the top of the positioning seat 303 and is located below the three fixing frames 13. The mobile phone housing body 17 is clamped by two clamping blocks 302. The height of the positioning seat 303 is higher than the height of the clamping blocks 302.

[0033] Specifically, the positioning seat 303 supports and positions the mobile phone shell body 17, and is convenient for cooperating with the two clamping blocks 302 to clamp and fix the mobile phone shell body 17. The positioning seat 303 is higher than the clamping block 302, which lifts the mobile phone shell body 17 and makes it higher than the clamping block 302, making it convenient for the top of the mobile phone shell body 17 to be exposed and friction tested with the grinding block.

[0034] When in use: the staff first places the mobile phone shell body 17 to be tested on the positioning seat 303, and then twists the double-threaded rod 10. When the double-threaded rod 10 rotates, it drives the guide slider 3022 to move, thereby driving the two clamping blocks 302 to move toward the side close to each other, so that the silicone sheets 3021 set on the two clamping blocks 302 can clamp and stabilize the two sides of the mobile phone shell body 17;

[0035] Start the cylinder 8, and the power output shaft of the cylinder 8 pushes the push plate 9 downward, thereby pushing the fixed frame 13 below the push plate 9 downward and gradually approaching the top of the mobile phone housing body 17 until the grinding block installed in the fixed frame 13 fits on the top of the mobile phone housing body 17;

[0036] Start the servo motor 4, and the power output shaft of the servo motor 4 rotates, thereby driving the eccentric wheel 5 to rotate. When the eccentric wheel 5 rotates, it will contact the movable seat 301, and push the movable seat 301 to move toward the side close to the support plate 6, and squeeze the reset spring 1201. When the eccentric wheel 5 does not contact the movable seat 301, the reset spring 1201 loses the squeezing force, thereby generating a rebound force, and pushes the movable seat 301 to move toward the side away from the support plate 6. As the eccentric wheel 5 continues to rotate and cyclically contacts the movable seat 301, the movable seat 301 can be reciprocated on the fixed seat 2. When the movable seat 301 reciprocates, it will drive the clamped mobile phone shell body 17 to rub against the three grinding blocks installed in the three fixed frames 13, thereby simulating the state of the mobile phone shell body 17 after being rubbed, and judging whether it is qualified;

[0037] Since the three fixing frames 13 are not equipped with grinding blocks, and the three grinding blocks are respectively a paint plate, a solid wood plate, and a plastic block with a pure cotton cloth cover, the paint plate and the solid wood plate can simulate the wear and tear of a user placing a mobile phone on a desktop (desks, computer tables, or office desks are mostly made of paint plates and solid wood plates), and the plastic block with a pure cotton cloth cover can simulate the wear and tear of a user placing a mobile phone in a pocket (in daily life, people mostly put their mobile phones in the pockets of clothes or pants, and the pockets are often made of pure cotton materials);

[0038] The grinding block is fixed in the fixed frame 13 by the locking rod 14 and the extrusion plate 15, and can be easily disassembled later. It is convenient for the staff to install grinding blocks of more materials in the fixed frame 13, thereby simulating the wear of the mobile phone shell body 17 when used in more environments, which can greatly increase the practicality of the present application.

[0039] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
