[0002] A resistive touch screen is a sensor that is basically a film plus glass structure. The adjacent surfaces of the film and the glass are coated with ITO (nano indium tin oxide) coating. ITO has good conductivity and transparency. When a touch operation is performed, the ITO on the lower layer of the film will contact the ITO on the upper layer of the glass, and the corresponding electrical signal will be transmitted through the sensor, sent to the processor through the conversion circuit, and converted into X and Y values ​​on the screen through calculation, thereby completing the click action and presenting it on the screen.

[0003] Manual assembly of the resistive touch screen and the display screen requires tooling, and then assembly to the protective housing is time-consuming and laborious. Utility Model Content

[0007] When the display screen is fixed, the position of the display screen can be restricted by passing the fixing bolts through the through holes on the display screen and connecting to the threaded holes on the protective housing body.

[0008] Preferably, the fixing bolts are passed through the back plate of the shell, and when the fixing bolts are connected to the threaded holes on the protective shell body, the position between the back plate of the shell and the protective shell body can be limited.

[0013] 2. There is no need to separately package the resistive touch screen and display screen. While optimizing the assembly process, it can also improve installation efficiency and achieve better actual application effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction to the technical solution of the utility model.

[0020] like Figure 1-2 As shown, as a protective shell of a tooling-integrated resistive touch display screen of the utility model, it includes a protective shell body 1, the protective shell body 1 is arranged as a frame structure, a step groove 6 is arranged on one side of the protective shell body 1, a resistive touch screen 2 is arranged at the position of the step groove 6 in the protective shell body 1, a display screen 3 bonded to the resistive touch screen 2 is arranged in the protective shell body 1, and the back of the protective shell body 1 is covered with a shell back plate 4.

[0021] Specifically, the protective shell body 1 is placed horizontally on a plane, the resistive touch screen 2 is placed horizontally in the stepped groove 6, and then the display screen 3 is placed on the protective shell body 1 and fits with the resistive touch screen 2. Finally, the shell back plate 4 is fixedly connected to the protective shell body 1 to complete the installation of the integrated resistive touch display screen. This installation process does not require separate fixed connection of the resistive touch screen 2 and the display screen 3, which can make the overall equipment installation efficiency higher, the installation more convenient, and the actual application effect better.

[0022] like Figure 2-3 As shown, threaded holes 7 are formed around the protective housing body 1, and through holes 8 are formed on the display screen 3 at positions corresponding to the threaded holes 7;

[0023] When the display screen 3 is fixed, the fixing bolts 5 pass through the through holes 8 on the display screen 3 and are connected to the threaded holes 7 on the protective housing body 1 , thereby limiting the position of the display screen 3 .

[0024] Through this structural setting, the protective shell body 1, the resistive touch screen 2, the display screen 3 and the shell back plate 4 can be connected into a whole, and the structural stability of the integrated resistive touch display screen finally formed is higher. At the same time, it is convenient to connect and limit the protective shell body 1, the resistive touch screen 2, the display screen 3 and the shell back plate 4, thereby improving the installation efficiency.

[0025] like Figure 1 As shown, the fixing bolts 5 are passed through the housing back plate 4 , and when the fixing bolts 5 are connected to the threaded holes 7 on the protective housing body 1 , the position between the housing back plate 4 and the protective housing body 1 can be limited.

[0026] like Figure 1 As shown, the plane area of ​​the display screen 3 is larger than the plane area of ​​the resistive touch screen 2 , and the resistive touch screen 2 can be completely covered, so that the display screen 3 has a better limiting effect on the resistive touch screen 2 .

[0027] like Figure 2 As shown, an arc chamfered structure is provided at the corner of the step groove 6 in the protective shell body 1, which can avoid bumping at the corners when installing the resistive touch screen 2, thereby avoiding damage to the resistive touch screen 2 during the installation process. In addition, through this structural setting, the resistive touch screen 2 can also be guided, so that the installation efficiency of the resistive touch screen 2 is higher and the actual application effect is better.

[0028] The technical scope of the present invention is not limited to the contents described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical concept of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
