[0002] Currently, touch screens are widely used, and are particularly suitable for applications such as public information inquiry, industrial control, video games, song and food ordering, multimedia teaching, and real estate pre-sales.

[0003] Touchscreens are an important information kiosks in subway stations, and regular maintenance is necessary to ensure their stable operation. However, due to aesthetic considerations, touchscreens are becoming increasingly larger, which complicates repair. Therefore, there is an urgent need to develop a touchscreen maintenance door mechanism suitable for large sizes (55 inches), offering high maintenance safety and preventing door deformation. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a touch screen maintenance door mechanism. The hinge between the door frame and the maintenance door is stable and reliable, which increases the number of times the maintenance door can be opened and closed and extends the service life of the equipment. At the same time, the slide rod and the limit slide rod bracket work together to lock the opening degree of the maintenance door in the maintenance state, which facilitates the installation and maintenance of the touch screen components.

[0005] The purpose of this utility model is achieved as follows:

[0006] A touchscreen maintenance door mechanism includes a door frame and a maintenance door with an embedded touchscreen component. The door frame and the maintenance door are hinged together by multiple hinge assemblies. A slide rod is provided between the bottom of the door frame and the maintenance door. One end of the slide rod is hinged to the door frame, and the other end is connected to a limiting slide rod bracket via a limiting shaft. The limiting slide rod bracket is fixed to the bottom of the maintenance door. The limiting slide rod bracket has a sliding groove corresponding to the limiting shaft. One end of the sliding groove has a limiting groove that communicates with the sliding groove. The limiting groove is close to the hinge assembly. The bottom of the door frame is provided with a sloped limiting support. The maintenance door is provided with a roller corresponding to the limiting support. The roller is fixed to the bottom of the maintenance door by a roller bracket.

[0007] Preferably, the hinge assembly includes a U-shaped hinge fixing plate, an outer hinge fixing plate, and a hinge shaft. One end of the U-shaped hinge fixing plate is fixed to the inside of the maintenance door, and the other end passes through the door frame and is connected to the outer hinge fixing plate through the hinge shaft. The outer hinge fixing plate is fixed to the outside of the door frame by a hinge plate welding fixing plate.

[0008] Preferably, the roller is positioned on the side of the maintenance door away from the hinge assembly to avoid the position of the limiting slide rod bracket.

[0009] Preferably, when the touch screen assembly is opened with the maintenance door, the limiting shaft at the end of the slide rod slides along the slide groove of the limiting slide rod bracket into the limiting groove, the limiting slide rod bracket is locked, and the opening degree of the maintenance door is locked.

[0010] Preferably, the touch screen assembly includes a 55-inch display, a display bezel, and a display mounting bracket, wherein the 55-inch display is positioned between the display bezel and the display mounting bracket.

[0011] The beneficial effects of this utility model are:

[0012] By setting up special hinge components, it is easy to disassemble and assemble the door frame and the maintenance door, ensuring that the hinge joint between the door frame and the maintenance door is stable and reliable, and there is no situation where the hinge shaft cannot be replaced due to damage later.

[0013] When the touch screen assembly is opened with the maintenance door, the limiting shaft at the end of the slide rod slides along the slide groove of the limiting slide rod bracket into the limiting groove, the limiting slide rod bracket is locked, and the opening degree of the maintenance door is locked, which facilitates the installation and maintenance of the touch screen assembly and greatly improves the safety of maintenance.

[0014] Since the maintenance door is in a closed state for a long time, rollers are installed at the bottom of the maintenance door to prevent it from sagging due to gravity and mechanical fatigue. When the door is closed, the rollers move with the maintenance door and reach the top along the slope of the limit support, which plays a supporting role for the door, reduces the load on the hinges, greatly increases the number of times the maintenance door can be opened and closed, and extends the service life of the equipment.

Detailed Implementation

[0021] See Figure 1-5 This utility model relates to a touch screen maintenance door mechanism, including a door frame 1 and a maintenance door 3 with an embedded touch screen assembly 2. The touch screen assembly 2 includes a 55-inch display 2.1, a display bezel 2.2, and a display mounting bracket 2.3. The 55-inch display 2.1 is positioned between the display bezel 2.2 and the display mounting bracket 2.3, providing positional protection for the 55-inch limiter 2.1. To prevent the maintenance door 3 from sagging due to excessive weight, the door frame 1 and the maintenance door 3 are hinged by multiple hinge assemblies 4. Next, the hinge assembly 4 includes a U-shaped hinge fixing plate 4.1, an outer hinge fixing plate 4.2, and a hinge shaft. One end of the U-shaped hinge fixing plate 4.1 is fixed to the inside of the maintenance door 3, and the other end passes through the door frame 1 and is connected to the outer hinge fixing plate 4.2 through the hinge shaft. The outer hinge fixing plate 4.2 is fixed to the outside of the door frame 1 by a hinge plate welding fixing plate 4.3, which facilitates the disassembly and assembly of the door frame 1 and the maintenance door 3, and ensures that the hinge joint between the door frame 1 and the maintenance door 3 is stable and reliable, and there is no situation where the hinge shaft cannot be replaced due to damage later.

[0022] A sliding rod 5 is provided between the bottom of the door frame 1 and the maintenance door 3. One end of the sliding rod 5 is hinged to the door frame 1, and the other end is connected to a limiting sliding rod bracket 7 via a limiting shaft 6. The limiting sliding rod bracket 7 is fixed to the bottom of the maintenance door 3. The limiting sliding rod bracket 7 has a sliding groove 7.1 corresponding to the limiting shaft 6. One end of the sliding groove 7.1 has a limiting groove 7.2, which communicates with the sliding groove 7.1 and is close to the hinge assembly 4. When the touch screen assembly 2 is opened with the maintenance door 3, the limiting shaft 6 at the end of the sliding rod 5 slides along the sliding groove 7.1 of the limiting sliding rod bracket 7 into the limiting groove 7.2, locking the opening of the maintenance door 3 and facilitating the installation and maintenance of the touch screen assembly 2.

[0023] The bottom of the door frame 1 is provided with a sloped limiting support 8, and the maintenance door 3 is provided with a roller 9 corresponding to the limiting support 8. The roller 9 is fixed to the bottom of the maintenance door 3 by a roller bracket 10.

[0024] The roller 9 is positioned on the side of the maintenance door away from the hinge assembly, allowing it to avoid contact with the limiting slide rod bracket 7. During equipment use, the maintenance door 3 is in a closed state for extended periods. To prevent the maintenance door from sagging due to gravity and mechanical fatigue, the roller 9 is installed below the maintenance door 3. When the door closes, the roller 9 moves with the maintenance door 3, reaching its apex along the slope of the limiting support 8, thus supporting the door, reducing the hinge load, significantly increasing the number of opening and closing cycles of the maintenance door, and extending the equipment's service life.

[0025] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
