Description

Technical Field

[0001] The utility model relates to the field of display screens, in particular to a test frame which is convenient for replacing various test screens. Background Art

[0002] Display comparison testing equipment requires the ability to accommodate various screen models. Currently, there's no suitable solution. Traditionally, the entire housing has been replaced to accommodate each screen model. This approach results in high replacement costs and inflexible operation, creating significant inconvenience for users.

[0003] Therefore, we propose a test framework that can easily replace various test screens to solve the above problems. Summary of the Invention

[0004] In order to solve the above technical problems, the utility model provides a test framework that can easily replace various test screens.

[0005] The utility model provides a test frame for conveniently replacing various test screens, including a large outer frame shell and a small fixed frame for adapting to a mobile phone screen module. The top of the large outer frame shell is provided with a mounting groove for accommodating the small fixed frame, and the inner side of the small fixed frame is provided with a accommodating groove adapted to the mobile phone screen module. A first magnet is symmetrically fixed in the large outer frame shell, and a second magnet that is symmetrically fixed in the small fixed frame and is attracted and matched with the first magnet. A cable avoidance hole is provided at the center of the small fixed frame.

[0006] Preferably, an edge groove is provided at the top edge of the installation groove, and a blocking protrusion that cooperates with the edge groove is provided at the edge of the small fixing frame.

[0007] Preferably, the edge of the edge groove is provided with a chamfer.

[0008] Preferably, the small fixing frame is provided with an avoidance hole for avoiding the metal frame of the mobile phone screen module.

[0009] Preferably, a limiting groove is provided at the top edge of the accommodating groove.

[0010] Preferably, the large outer frame shell is provided with a notch for facilitating the removal of the small fixing frame.

[0011] Compared with the related art, the present invention has the following beneficial effects:

[0012] Reduce replacement costs:

[0013] The traditional method requires replacing the entire casing to match different screen models, which is costly.

[0014] The new solution only requires replacing the small fixed frame, significantly reducing replacement costs.

[0015] Improve operational flexibility:

[0016] The traditional replacement method is cumbersome and inconvenient for users to quickly replace the screen.

[0017] The new solution adopts the method of a large outer frame shell with a small fixed frame, which is easy and quick to operate and improves the user's operational flexibility.

[0018] Adapt to diverse needs:

[0019] The shape of the small fixing frame, the size of the receiving slot, and the position of the avoidance hole can all be customized according to the specific screen model.

[0020] This design enables the test framework to perfectly adapt to various models of mobile phone screen modules to meet the diverse needs of users.

[0021] Enhanced stability:

[0022] The small fixing frame is fixed by magnetic attraction to ensure that it will not move or fall off during testing.

[0023] The cooperation between the edge groove and the blocking protrusion further enhances the stability. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0030] Please refer to Figures 1 to 4A test frame that allows for easy replacement of various test screens consists of a large outer frame 1 and a small fixed frame 2 adapted to accommodate a mobile phone screen module. The top of the large outer frame 1 features a mounting slot 3 specifically designed to accommodate the small fixed frame 2. Inside the small fixed frame 2 is a receiving slot 4 that fully accommodates the mobile phone screen module.

[0031] To more securely hold the small fixed frame 2, first magnets 5 are symmetrically fixed within the large outer shell 1, while second magnets 6, which engage and attract the first magnets 5, are symmetrically fixed within the small fixed frame 2. This ensures that the small fixed frame 2 is securely mounted within the large outer shell 1 through the magnetic attraction. A cable clearance hole 7 is also located in the center of the small fixed frame 2 to ensure smooth connection of the phone's cable.

[0032] The shape of the small fixed frame 2 is adaptively adjusted according to different models of mobile phone screen modules. The size of its receiving slot 4 and the position of the avoidance hole 11 are customized according to the specific screen model. This ensures that the small fixed frame 2 can perfectly adapt to various models of mobile phone screen modules.

[0033] In addition, a test mainboard is provided in the large outer frame housing 1, and a connector for connecting to the mobile phone cable is provided on the test mainboard. This enables the test frame to conveniently transmit and communicate data with the mobile phone screen module.

[0034] At the top edge of the mounting slot 3, we have an edge groove 8, and at the edge of the small fixed frame 2, we have a blocking protrusion 9 that cooperates with the edge groove 8. The blocking protrusion 9 can be installed in the edge groove 8, thereby further fixing the position of the small fixed frame 2. At the same time, the edge of the edge groove 8 is also provided with a chamfer 10, which facilitates the user to guide the installation of the small fixed frame 2 and ensures that it enters the mounting slot 3 more smoothly.

[0035] In order to meet the installation requirements of different types of mobile phone screen modules, the small fixed frame 2 is also provided with a clearance hole 11 for avoiding the metal frame of the mobile phone screen module. Like this, even if the mobile phone screen module has a metal frame, it can also be installed in the small fixed frame 2 smoothly.

[0036] A limiting groove 12 is further provided at the top edge of the accommodating groove 4. The limiting groove 12 can accommodate the edge of the mobile phone screen module, thereby further fixing the position of the screen module to prevent it from moving or falling off during the test process.

[0037] In order to facilitate the user to take out the small fixing frame 2 for replacement, a notch 13 is further provided on the large outer frame shell 1. In this way, the user can easily remove the small fixing frame 2 from the installation slot 3 through the notch 13 and then replace it.

[0038] In summary, this solution utilizes a large outer shell housing encased in a small fixed frame, enabling lightweight replacement. Users simply replace the corresponding small fixed frame when replacing different screen models. This approach not only reduces replacement costs but also increases operational flexibility, providing significant user convenience. Furthermore, through precise design and adjustment, we ensure that the test framework perfectly adapts to various mobile phone screen module models, meeting diverse user needs.
