[0001] The utility model relates to the technical field of a touch display screen, in particular to a high-intensity and low-reflection touch display screen. Background Art

[0002] With the popularity of smart devices (smart phones, tablet computers, car navigation systems, etc.), touch screens are increasingly widely used, especially high-strength, low-reflectivity touch screens, which are installed in household appliances such as refrigerators and washing machines. Touch screens allow users to operate the host by simply touching the icons or text on the computer screen with their fingers, thus getting rid of keyboard and mouse operations and making human-computer interaction more straightforward. They are mainly used in information inquiries in public halls, leadership offices, electronic games, song and food ordering, multimedia teaching, and pre-sale of air tickets and train tickets. The products are mainly divided into three categories: capacitive touch screens, resistive touch screens, and surface acoustic wave touch screens.

[0003] In the prior art, a high-strength, low-reflection touch display screen includes a touch display module and a fixed plate. The touch display module is installed on the fixed plate to be assembled into an integral part and installed together on the home appliance. When the existing touch display module is installed on the fixed plate, the touch display module is embedded in the mounting groove of the fixed plate, and the side wall of the touch display module is fixed to the groove wall of the mounting groove by double-sided adhesive, so that the touch display module is fixed to the fixed plate. However, when the touch display module with this installation structure needs to be repaired, the touch display module needs to be torn off the fixed plate from the adhesive, which can easily cause damage to the touch display module and cannot be completely removed from the fixed plate, making it inconvenient to disassemble and repair. In addition, the four sides of the touch display module are adhered to the groove wall of the mounting groove, and the installation stability is also poor. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a high-strength and low-reflection touch display screen.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: it includes a display screen shell, a fixed block is provided on the peripheral wall of the display screen shell, the fixed block includes a fixed knob, the fixed block includes a fixed base, a limited tooth is fixed inside the display screen shell, a connecting column is fixed at the bottom of the fixing knob, an expanded tooth is fixed at the bottom of the connecting column, a connecting key is fixed at the upper end of the fixed base, a latch tooth is fixed on the upper end surface of the connecting key, a supporting spring is fixed on the outer wall of the fixed base, and the upper end surface of the supporting spring contacts the bottom of the display screen shell. In the prior art, a high-strength and low-reflection touch display screen includes a touch display module and a fixed plate, the touch display module is installed on the fixed plate to be assembled into an integral part, and is installed together on the household appliance. When the existing touch display module is installed on the fixed plate, the touch display module is embedded in the mounting groove of the fixed plate, and the side wall of the touch display module is fixed to the groove wall of the mounting groove by double-sided adhesive, so that the touch display module is fixed on the fixed plate. However, when the touch display module of this installation structure needs to be repaired, the touch display module needs to be torn off the fixed plate from the adhesive, which is easy to cause damage to the touch display module, and it cannot be completely removed from the fixed plate, which is inconvenient to disassemble and repair. In addition, the four sides of the touch display module are adhered to the groove wall of the installation groove, and the installation stability is also poor. By using a fixed block for installation, when the user needs to install a high-strength low-reflection touch display screen, the fixed base is installed in the corresponding square groove, and then the display screen is pressed into the fixed base. When the card teeth at the upper end of the fixed base are raised beyond the position of the limit teeth, the fixed knob is pressed into the circular groove in the display screen housing. When the expanded teeth enter the inside of the card teeth, due to extrusion, the card teeth are expanded to the surroundings. At this time, the support spring of the outer wall of the fixed base is squeezed and stretched, which indirectly fixes the card teeth more on the limit teeth to achieve fixation. When the display screen needs to be repaired and disassembled, the fixed knob is pulled out to disassemble the display screen, thereby making the display screen installation and subsequent maintenance easier.

[0006] Preferably, a fixing bolt is fixed inside the display screen shell, a fixing plate is fixed inside the display screen shell by the fixing bolt, an air gathering ring is fixed to the side wall of the fixing plate, a cooling fan is rotatably connected inside the air gathering ring, a fixing bolt is fixed to the side wall of the display screen shell, and a cooling plate is fixed to the display screen shell by the fixing bolt. In the prior art, the existing touch screen has poor heat dissipation, which reduces the durability of the touch screen and also causes extremely high heat to be generated during operation. The heat accumulation will cause the touch screen to burn due to high temperature. The utility model enhances the airflow exchange by means of a cooling fan to dissipate the heat, thereby preventing the display screen from self-destructing due to high temperature.

[0007] Preferably, a latch assembly is provided on the side wall of the display screen housing, and the latch assembly includes a plug plate. A display groove is provided on the upper end surface of the display screen housing, and fixing teeth are fixed on the inner wall of the display groove. Tooth grooves are provided at both ends of the plug plate, and a luminous strip is fixed on the upper end surface of the plug plate. In the prior art, when a user needs to use the display screen at night, indoor fluorescent lamps and other light sources are often turned off in order to save electricity. At this time, since the touch screen is automatically turned off, the user often cannot find the placement of the touch screen, and sometimes accidentally squeezes or touches the touch screen, which is extremely inconvenient to use. By providing display grooves at both ends of the display screen, installing latches in the grooves, and emitting light with the help of the luminous strip fixed on the upper end of the latch, it is possible to find the display screen more quickly in dark conditions such as at night.

[0008] Preferably, the expanded tooth has a frustum-shaped appearance, and the frustum-shaped oblique cross-section makes it more convenient to press and fix the knob.

[0009] Preferably, the upper and lower ends of the cross section of the limiting teeth have curvatures, and the transition of the curvatures enables smoother installation of the display housing.

[0010] Preferably, a rubber sleeve is fixed to the peripheral wall of the fixed knob, and the high friction of the rubber sleeve can reduce slipping when pressing the fixed knob and prevent it from falling off the display screen housing.

[0011] Preferably, there is a gap between the latch assembly and the display screen housing, so that plugging and unplugging the plug board is easier.

[0012] Beneficial Effects

[0013] 1. In the prior art, the high-intensity, low-reflection touch display screen includes a touch display module and a fixing plate. The touch display module is installed on the fixing plate to be assembled into an integral part and installed together on the home appliance. When the existing touch display module is installed on the fixing plate, the touch display module is embedded in the installation groove of the fixing plate, and the side wall of the touch display module is fixed to the groove wall of the installation groove by double-sided adhesive, so that the touch display module is fixed to the fixing plate. However, when the touch display module with this installation structure needs to be repaired, the touch display module needs to be torn off the fixing plate from the adhesive, which is easy to damage the touch display module and cannot be completely removed from the fixing plate, making it inconvenient to disassemble and repair. In addition, the touch display module is adhered to the groove wall of the installation groove on all sides, and the installation stability is also poor. By using a fixed block for installation, when the user needs to install a high-strength and low-reflection touch display screen, the fixed base is installed in the corresponding square groove, and then the display screen is pressed into the fixed base. When the latching teeth at the upper end of the fixed base are raised above the position of the limit teeth, the fixed knob is pressed into the circular groove in the display screen shell. When the expanded teeth enter the inside of the latching teeth, the latching teeth are expanded to the surroundings due to extrusion. At this time, the supporting spring of the outer wall of the fixed base is squeezed and stretched, which indirectly fixes the latching teeth more on the limit teeth to achieve fixation. When the display screen needs to be repaired and disassembled, the fixing knob is pulled out to disassemble the display screen, thereby making the installation and subsequent maintenance of the display screen easier.

[0014] 2. In the prior art, the existing touch screen has poor heat dissipation, which reduces the durability of the touch screen and also generates extremely high heat during operation. The heat accumulation will cause the touch screen to burn due to high temperature. The utility model uses a cooling fan to enhance airflow exchange and send out heat, thereby preventing the display screen from self-destructing due to high temperature.

[0015] 3. In the prior art, when users need to use the display screen at night, they often turn off indoor fluorescent lights and other light sources in order to save electricity. At this time, since the touch screen is automatically turned off, the user often cannot find the placement of the touch screen, and sometimes accidentally squeezes or touches the touch screen, which is extremely inconvenient to use. By opening display slots at both ends of the display screen, installing latches in the slots, and emitting light with the help of a light-emitting strip fixed at the upper end of the latch, it is possible to find the display screen more quickly in dark conditions such as at night.
