DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings.

[0021] The touch display screen of the utility model which is convenient for maintenance, such as Figures 1 to 5 As shown, it includes a touch display panel assembly 1 and a middle frame 3, as shown Figure 7 As shown, the middle frame 3 is formed with a groove 301 which is open to the front. Figure 3 to Figure 4 As shown, the groove 301 is located at the periphery of the touch display panel assembly 1. In other words, the groove 301 is formed on the middle frame 3 all around. Figure 4 and Figure 6 As shown, the LED display belt 4 is arranged in the groove 301, and the front side of the LED display belt 4 is provided with LED lamp beads, so that the LED display belt 4 emits light forward; Figures 1 to 5 As shown, the touch display screen of the utility model which is easy to maintain also includes a protective cover plate 2 and a light-transmitting connecting strip 5. The protective cover plate 2 is arranged on the front side of the touch display panel assembly 1. The protective cover plate 2 is used to protect the touch display panel assembly 1. Figure 4 As shown, the light-transmitting connecting strip 5 is fixedly connected to the rear side of the protective cover plate 2. Specifically, the protective cover plate 2 may be a glass plate. The light-transmitting connecting strip 5 may be bonded to the protective cover plate 2. The light-transmitting connecting strip 5 is arranged on the corresponding front side of the LED display strip 4. The light-transmitting connecting strip 5 is detachably fixedly connected to the middle frame 3. The light-transmitting connecting strip 5 may be made of light-transmitting plastic. For example, the light-transmitting connecting strip 5 may be connected to the middle frame 3 by fasteners or by a buckle structure.

[0022] like Figure 4 As shown, the LED display strip 4 emits light forward. Since the light-transmitting connecting strip 5 is arranged at the corresponding front side of the LED display strip 4, the light passes through the light-transmitting connecting strip 5, and then passes through the edge of the protective cover plate 2 and emits forward, so that the user in front of the touch screen can see the corresponding part of the LED display strip 4 glowing. Among them, the edge of the protective cover plate 2 can be set as a scattered light area to scatter the light emitted forward by the LED display strip 4. Since the light-transmitting connecting strip 5 is detachably fixedly connected to the middle frame 3, as shown in FIG. Figure 4As shown, when the LED display strip 4 needs to be replaced, the light-transmitting connecting strip 5 and the middle frame 3 can be relatively disassembled, and the light-transmitting connecting strip 5 and the protective cover plate 2 can be separated from the middle frame 3, and then the LED display strip 4 located in the groove 301 can be taken out and replaced, and then the light-transmitting connecting strip 5 and the protective cover plate 2 are covered back into the middle frame 3, and the light-transmitting connecting strip 5 and the middle frame 3 are restored to be fixedly installed. It can be seen that by providing the light-transmitting connecting strip 5, the protective cover plate 2 and the middle frame 3 are prevented from being bonded and fixed, which is conducive to convenient replacement of the LED display strip 4, that is, the touch display screen of the utility model is easy to maintain. Since the light-transmitting connecting strip 5 can be made of existing translucent plastic, such as polyvinyl chloride, the light-transmitting connecting strip 5 can have the effect of diverging light.

[0023] Furthermore, if Figure 7 As shown, the middle frame 3 includes a rear plate portion 31, and the rear plate portion 31 is formed with a mounting hole 302, as shown in FIG. Figure 4 As shown, the light-transmitting connecting strip 5 is formed with a first screw hole 501, the light-transmitting connecting strip 5 is close to the front side of the rear plate 31, and a connecting strip fixing screw 7 is provided in the mounting hole 302, and the connecting strip fixing screw 7 is screwed with the first screw hole 501. The mounting structure of the middle frame 3 and the light-transmitting connecting strip 5 is simple, and the mounting and dismounting of the connecting strip fixing screw 7 is simple and convenient, which is also conducive to the reliable fixing of the light-transmitting connecting strip 5 and the middle frame 3. Figure 7 As shown, the middle frame 3 includes a side plate portion 32, and the rear end of the side plate portion 32 is connected to the outer end of the rear plate portion 31 as a whole. Figure 4 As shown, the side plate portion 32 surrounds the outer sides of the light-transmitting connecting strip 5 and the protective cover plate 2 , so the side plate portion 32 plays a role in protecting the light-transmitting connecting strip 5 and the protective cover plate 2 .

[0024] Furthermore, if Figure 7 As shown, the rear plate portion 31 is formed with a second screw hole 303. Figure 2 and Figure 5 As shown, a back shell 6 is provided on the rear side of the touch display panel assembly 1, that is, the back shell 6 covers the back side of the touch display panel assembly 1. Figure 4 As shown, the back shell 6 is attached to the rear side of the rear plate 31, and a back shell fixing screw 8 is installed in the second screw hole 303. The back shell fixing screw 8 is adapted to pass through the back shell 6. The back shell fixing screw 8 can be a cross-slot countersunk screw. Since the back shell 6 is attached to the rear side of the rear plate 31, it is necessary to remove the back shell 6 first before removing the connecting strip fixing screw 7. However, the back shell 6 can cover the mounting hole 302, which is beneficial to the beauty of the touch display screen.

[0025] Furthermore, if Figure 7 As shown, the mounting hole 302 is configured as a countersunk hole. Figure 4 As shown, the head of the connecting bar fixing screw 7 can be hidden in the middle frame 3 to avoid interference between the connecting bar fixing screw 7 and the back shell 6.

[0026] Furthermore, if Figure 5 As shown, the four light-transmitting connecting strips 5 are integrally arranged in a frame shape, which is beneficial to improving the installation stability of the middle frame 3 and the protective cover plate 2, and is beneficial for each installation hole 302 to be easily aligned with the first screw hole 501, so as to facilitate the assembly of the touch display screen.

[0027] Furthermore, the light-transmitting connecting strip 5 is configured as an acrylic light-transmitting strip, which has good light transmittance and good mechanical strength.
