DETAILED DESCRIPTION

[0035] The technical solution of the present invention will be further described in detail below in conjunction with specific implementation methods.

[0036] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0037] like Figure 1 and Figure 2 As shown, the high-resolution anti-interference capacitive touch screen provided in this embodiment includes a mounting shell 2 for mounting a capacitive touch screen body 1, and a protective film 11 is provided on the outer surface of the capacitive touch screen body 1. The provision of the protective film 11 can protect the outer surface of the capacitive touch screen body 1 from scratches, dirt and other damage, thereby extending the service life of the touch screen. It should be noted that the protective film 11 has high transparency to reduce the impact on the display effect of the capacitive touch screen. The protective film 11 with good light transmittance can ensure that the high-resolution image of the capacitive touch screen is clearly displayed, and will not be blurred or distorted in color due to the presence of the protective film 11. The protective film 11 has good electrostatic dissipation capabilities and can effectively reduce the impact of electrostatic interference on the capacitive touch screen. Electrostatic interference may cause the touch screen to be accidentally touched or the sensitivity to decrease, and the protective film 11 with good electrostatic dissipation capabilities can effectively avoid this problem, thereby improving the anti-interference performance of the touch screen. In addition, by adopting a denser sensor layout, the number of identifiable touch points on the touch screen can be increased, thereby improving the resolution. This layout also helps improve the touchscreen's anti-interference capabilities, as more sensors can more accurately detect touch locations and reduce the possibility of false touches. By increasing the number of filters and adjusting the filter parameters, sensitivity to interference can be reduced, thereby improving the touchscreen's resolution and anti-interference capabilities.

[0038] like Figure 1 and Figure 2 As shown, the mounting housing 2 is provided with a disassembly and assembly mechanism for securing the capacitive touch screen body 1. The capacitive touch screen body 1 is equipped with a docking structure for use with the disassembly and assembly mechanism. The docking structure comprises a pad 12 secured to the lower surface of the capacitive touch screen body 1 and four positioning rods 13 secured to the lower surface of the pad 12. The four positioning rods 13 are arranged in a rectangular shape. By providing the disassembly and assembly mechanism and the docking structure, such as the pad 12 and positioning rods 13, the installation and removal of the capacitive touch screen body 1 within the mounting housing 2 is simplified and faster. This design reduces the time and labor required to install or replace the touch screen, improving maintenance efficiency.

[0039] like Figure 1-Figure 7 As shown, the disassembly and assembly mechanism includes a first piston structure 4, a second piston structure 5 and a pushing structure 6, and a positioning member is arranged between the second piston structure 5 and the pushing structure 6, wherein the positioning member is composed of a first insertion rod 7 and a second insertion rod 8, and the first insertion rod 7 and the second insertion rod 8 are arranged opposite to each other; specifically, the first piston structure 4 and the second piston structure 5 are connected, and a linkage structure 9 is arranged between the second piston structure 5 and the pushing structure 6; the first piston structure 4 consists of a piston cylinder 401, a first piston block 402 sliding inside the piston cylinder 401, and a piston rod 403 fixed on the upper surface of the first piston block 402 and extending to the outside of the mounting shell 2, and a positioning sleeve 3 for positioning the first piston structure 4 is arranged above the mounting shell 2. The interior of the mounting shell 2 is hollow, and an access panel 21 is bolted to its top side. An opening 22 for the capacitive touch screen body 1 is provided within the access panel 21. A mounting slot 23 is provided on the bottom wall of the mounting shell 2. The spacer 12 extends into the slot 23 and engages with the interior of the slot 23 via the positioning rod 13, thereby providing preliminary fixation for the capacitive touch screen body 1. The pushing structure 6 is located within the slot 23, and the piston cylinder 401 is secured within the mounting shell 2. Both the positioning sleeve 3 and the piston rod 403 have positioning holes 404, and a positioning shaft for securing the piston rod 403 is inserted into the positioning hole 404. When the first piston block 402 moves downward, the positioning shaft is inserted into the positioning hole 404 to secure the first piston block 402, thereby achieving positioning of the capacitive touch screen body 1.

[0040] like Figure 1 、 Figure 3-Figure 5 As shown, the second piston structure 5 includes a piston tube 501 disposed within the mounting housing 2 and located above the mounting groove 23, a reset structure disposed within the piston tube 501, and a second piston block 505. The two sides of the second piston block 505 are respectively connected and fixed to the reset structure and the second insertion rod 8. It should be noted that the interiors of the piston cylinder 401 and the piston tube 501 are both hollow. The end of the piston tube 501 away from the second insertion rod 8 is fixed to the outer surface of the piston cylinder 401. The interior of the piston cylinder 401 is provided with a through hole 405 that communicates with the piston tube 501. The reset structure includes a mounting bracket 502 fixed to the inner wall of the piston tube 501, a connecting rod 503 that movably extends through the interior of the mounting bracket 502, a connecting block 504 welded to one end of the connecting rod 503, and a first reset spring 506 fixed between the connecting block 504 and the mounting bracket 502. The connecting block 504 is fixed to the outer surface of the second piston block 505 by bolts. The first reset spring 506 surrounds the exterior of the connecting rod 503. After the first piston structure 4 releases the pressure, the second piston block 505 and the slide 601 of the pushing structure 6 are reset by the elastic force of the first reset spring 506. This automatic reset mechanism improves the reliability and stability of the device.

[0041] To cooperate with the first piston structure 4 and the second piston structure 5, as shown in FIG. Figure 3-Figure 7 As shown, the pushing structure 6 includes a slide 601 slidably disposed within the mounting groove 23, an adjustment block 602 welded to the right side of the slide 601, a connector disposed within the adjustment block 602 and connected to the first insertion rod 7, and a guide structure fixed to the outer surface of the slide 601 and connected to the inner bottom wall of the mounting groove 23. The connector includes a first connecting rod 604 fixed to the side of the first insertion rod 7 near the slide 601, a shaft 605 fixed to the other end of the first connecting rod 604, and a first roller 603 mounted on the other end of the shaft 605 via a bearing. A first rolling groove 606 adapted to the first roller 603 is defined within the adjustment block 602, and the first roller 603 and the first rolling groove 606 are in rolling engagement. The first roller 603 and the first rolling groove 606 reduce frictional resistance, making the pushing structure 6 move more smoothly and improving operational efficiency.

[0042] It's worth noting that the linkage between the push structure 6 and the second piston structure 5 is achieved through the connection between the internal connecting components of the adjustment block 602, including the first connecting rod 604, the shaft 605, and the first roller 603, and the first insertion rod 7. When the piston rod 403 of the first piston structure 4 moves, it pushes the second piston block 505 through the through-hole 405 in the piston cylinder 401 and the piston tube 501, which in turn cooperates with the linkage structure 9 to drive the slide 601 of the push structure 6 to slide. This design ensures a smooth and accurate pushing process.

[0043] To ensure the stable lifting of the slide 601, specifically, Figure 6 As shown, the guide structure includes a stopper 607 fixed to the outer surface of the slide 601, a guide rod 608 fixed to the inner bottom wall of the mounting groove 23, and a second return spring 609. The top side of the second return spring 609 is fixed to the bottom surface of the stopper 607, and the top end of the guide rod 608 extends through the interior of the stopper 607. The installation of the stopper 607, guide rod 608, and second return spring 609 ensures the stability of the slide 601 during movement and prevents it from deviating from the track. Furthermore, the second return spring 609 provides additional assistance when the slide 601 returns to its original position, further enhancing operational convenience.

[0044] like Figure 3-Figure 7As shown, the linkage structure 9 includes a second connecting rod 901 fixed to the lower surface of the second insertion rod 8, a third connecting rod 902 fixed to the end of the second connecting rod 901 away from the second insertion rod 8, and a second roller 903 rotatably mounted on the end of the third connecting rod 902 near the slide 601. The slide 601 has a second rolling groove 904 formed within it, which rolls with the second roller 903. The combination of the second connecting rod 901, the third connecting rod 902, and the second roller 903 forms a stable linkage mechanism. When the second insertion rod 8 moves, the second roller 903 rolls within the second rolling groove 904 through the transmission of the second and third connecting rods 901, 902, thereby driving the slide 601 to move. This design ensures the smoothness and accuracy of the linkage process, reducing the shaking or deviation caused by loose components or friction. A stop seat 905 is fixed to the inner bottom wall of the mounting slot 23 to limit the position of the first connecting rod 604 and the second connecting rod 901. The first connecting rod 604 and the second connecting rod 901 slide through the interior of the limit seat 905. During use, the limit seat 905 serves as a limit for the first connecting rod 604 and the second connecting rod 901, preventing them from moving beyond a predetermined range. This design protects the linkage structure 9 from damage caused by excessive stretching or compression, thereby extending the service life of the device.

[0045] Furthermore, because the linkage structure 9 has a certain degree of flexibility and adjustability (e.g., by adjusting the length of the second link 901 and the third link 902 or the position of the second roller 903), it can be adapted to different installation environments and requirements. This design ensures that the device maintains good performance and stability in a variety of scenarios.

[0046] like Figure 1-Figure 7 As shown, the principle of the high-resolution anti-interference capacitive touch screen provided by this embodiment is as follows:

[0047] First, the capacitive touch screen body 1 is preliminarily plugged and fixed to the mounting groove 23 in the mounting shell 2 through the pad 12 and four positioning rods 13 on its lower surface. The piston tube 501 of the second piston structure 5 is connected to the piston cylinder 401 through the through hole 405.

[0048] Then, when the piston rod 403 is pushed downward, the first piston block 402 slides in the piston cylinder 401, compressing the internal air and transmitting it to the piston tube 501 through the through hole 405. This causes the second piston block 505 to move in the piston tube 501 in a direction away from the piston cylinder 401, and then pushes the pushing structure 6 through the second insertion rod 8 and the linkage structure 9. The movement of the second insertion rod 8 drives the second roller 903 to roll in the second rolling groove 904 of the slide 601 through the second connecting rod 901 and the third connecting rod 902.

[0049] The slide 601 slides up and down in the mounting groove 23, and the first roller 603 rolls in the first rolling groove 606, so that the first insertion rod 7 also moves accordingly. As the slide 601 slides, the first insertion rod 7 and the second insertion rod 8 reach their final positions respectively, thereby firmly fixing the capacitive touch screen body 1.

[0050] For example, certain words are used in the specification and claims to refer to specific components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of the components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term and should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.
