Description

Technical Field

[0001] This utility model relates to the field of fixtures, and in particular to a fixture for testing the aging of a display screen. Background Technology

[0002] Display screen aging test fixtures are tools used during display screen aging tests to help control the position or movement of the display screen during installation and positioning. They are widely used in display screen production and testing.

[0003] However, existing fixtures usually cannot simulate the actual usage of the display screen in different installation environments. The single test angle leads to the disconnect between aging data and actual application scenarios, and cannot fully expose potential defects. At the same time, most equipment uses bolt fastening or rigid buckles, which is not easy to adapt to display screens of different sizes and thicknesses, and lacks the ability to fine-tune the tilt angle. During installation, the screen is prone to uneven stress, and displacement and loosening may occur during the test, affecting the accuracy of the data. In addition, traditional solutions require manual handling of heavy frames and repeated disassembly and assembly of fixtures. During batch testing, operators need to adjust the position of each screen one by one, which is a cumbersome and time-consuming process. Utility Model Content

[0004] The main purpose of this utility model is to provide a display screen aging test fixture, which can effectively solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A display screen aging test fixture includes a support frame, a support base rod, and movable wheels. The support base rod is welded to the lower end of the support frame. A plurality of movable wheels are fixedly installed at both ends of the support base rod. A central mounting plate is fixedly installed on the top of the support frame. A transmission box is fixedly installed at the rear end of the central mounting plate. A rotating mounting plate is movably installed at the front end of the central mounting plate. A frame rod is fixedly installed at the front end of the rotating mounting plate. Display screen mounting structures are fixedly installed on both sides of the front end of the frame rod.

[0007] As a further embodiment of this utility model, a rotating handle is movably mounted on the outside of the transmission box, and the shaft of the transmission box passes forward through the central mounting plate and is fixedly connected to the rotating mounting plate.

[0008] As a further embodiment of this utility model, a positioning pin is fixedly installed at the upper end of the support frame, and the end of the positioning pin is inserted into the slot on the outside of the rotating mounting plate.

[0009] As a further embodiment of this utility model, the frame rod is located in front of the support frame, and the rotating mounting plate rotates around the front of the central mounting plate.

[0010] As a further embodiment of this utility model, the display screen mounting structure includes a rotating mounting base, a locking knob, a rotating mounting rod, a clamping clamp, and a display screen placement frame. The rotating mounting base is fixedly mounted on the front end of the frame rod, the locking knob is fixedly mounted on the outside of the rotating shaft of the rotating mounting base, the rotating mounting rod is fixedly mounted on the front end of the rotating shaft of the rotating mounting base, and multiple clamping clamps and the display screen placement frame are fixedly mounted on the outside of the rotating mounting rod.

[0011] As a further embodiment of this utility model, the clamping base is located above the display screen mounting bracket, the rotating mounting rod rotates around the rotating axis of the rotating mounting base, and the clamping bases and the display screen mounting bracket on both sides are symmetrically arranged and installed.

[0012] Compared with the prior art, the present invention has the following advantages: Through the linkage design of the transmission box and the rotating handle, the user can easily rotate the handle to drive the shaft in the transmission box, thereby driving the rotating mounting plate to rotate around the front of the central mounting plate, so that the frame rod and the display screen mounting structure can be adjusted as a whole, which is convenient for simulating the aging of the display screen in different installation environments, such as vertical or tilted placement tests. This not only expands the coverage of test scenarios, but also simplifies the operation process and improves test efficiency.

[0013] With the designed display mounting structure, the rotating mounting rod can rotate around the pivot of the rotating mounting base and be precisely positioned by the locking knob, allowing the display mounting bracket and clamping bracket to adjust their tilt angle. The clamping bracket is located above the display mounting bracket and is used to clamp and fix the display, ensuring that the display will not shift or loosen during the test. It can fine-tune a single display to accommodate screens of different sizes and types. At the same time, the symmetrically arranged clamping brackets and display mounting brackets support the simultaneous testing of multiple displays, improving the efficiency of batch testing.

[0014] Meanwhile, the welded and fixed design of the support frame and the central mounting plate provides a high-strength support foundation, while the front-mounted layout of the rotating mounting plate and frame rods ensures that the test area is spacious and easily accessible. Combined with the portability of the moving wheels and the locking function of the positioning pins, the entire fixture remains stable during the test, reducing vibration interference and thus improving the accuracy of aging test data. Furthermore, the modular design, such as the fixed installation of the clamping clamp and the display screen mounting bracket, simplifies the installation and disassembly process of the display screen and reduces operational complexity.
