The opposite side of the arm of the several frame rods 20 is fixedly installed with a rotation spring 30, and one end of the rotation spring 30 is fixedly connected to the inner wall of the clamping cavity 2.

[0037] Among them, the operation panel body 1 is composed of a substrate 101, a transparent conductive layer 102, an insulating layer 103, and a display panel 104, and the arrangement order of the substrate 101, the transparent conductive layer 102, the insulating layer 103, and the display panel 104 from front to back is display panel 104, transparent conductive layer 102, substrate 101, insulating layer 103.

The material of the substrate 101 is glass, the material of the transparent conductive layer 102 is ITO, and the material of the insulating layer 103 is polyimide film.

[0038] Specifically, the surfaces of several push plates 5 are respectively slidably connected to the inner walls of the corresponding card-connecting cavities 2, the rear ends of several pressure cylinders 7 respectively penetrate the rear sides of the inner walls of the corresponding card-connecting cavities 2 and extend to the back of the operating panel body 1, one end of several connecting rods 14 penetrates the inner wall of the card-connecting cavity 2 and extends to the inside of the sliding cavity 15, the opposite ends of several rack rods 20 are respectively rotatably connected to the opposite side of the inner wall of the corresponding card-connecting cavity 2, the surfaces of several extrusion plates 24 are respectively rotatably connected to the inner walls of the card interfaces 3, the sealing barrier ring 8 is an arc-shaped frame structure made of conductive rubber material, the several wrapping pads 25 are all plate structures made of conductive rubber, and the thickness of the wrapping pads 25 is set to three millimeters, the material of the absorbing plate 31 is a ferrite absorbing plate, and the spacing between the diamond openings opened in the absorbing plate 31 is set to 1mm-5mm.

[0039] It should be noted that the setting positions of the several limit rings 12 can ensure that the distance between the second card table 11 and the first card table 10 is five millimeters. The first card table 10 and the second card table 11 are both frustum structures. The several T-shaped connecting rods 17 are all composed of two perpendicular rods fixedly formed, and the diameter of the rod body of the combined structure close to the push plate 5 is 1.5 times the diameter of the other rod body. The angle between the several second hole blocks 21 and the two corresponding first hole blocks 18 is θ, and 105°≤θ≤145°. The back of the several first card tables 10 is fixedly connected with a damper 26, and the back of the first card table 10 is fixedly connected with a push spring 27 around the damper 26. The damper 26 and the push spring 27 can make the first card table 10 and the second card table 11 have a certain distance, which is convenient for the trapezoidal block 13 to limit and resist the first card table 10. The size of the spring elastic potential energy in this device is, from large to small, the first spring 6, the second spring 28, and the push spring 27.

[0040] The working principle of the above embodiment is:

[0041] When the device is in use, the operation plate body 1 is directly pushed into the position to be installed. The installation position of this operation plate body 1 is a matching groove body. When installing, it is only necessary to press the operation plate body 1 to the installation position with a suction cup. When the operation plate body 1 contacts the installation position, the pressure cylinder 7 contacts the installation position first, and the pressure cylinder 7 pushes the push plate 5 to move forward. The push plate 5 drives the first card platform 10 to move toward the trapezoidal block 13 through the moving column 9. The inclined surface of the trapezoidal block 13 contacts the inclined surface of the first card platform 10, and when the trapezoidal block 13 slides to the rear side of the first card platform 10, under the elastic force of the second spring 28, the trapezoidal block 13 can contact the back of the first card platform 10, and under the elastic force of the first spring 6, it can ensure that the trapezoidal block 13 and the first card platform 10 are limited.

[0042] When the push plate 5 is pushed, the push plate 5 drives the first hole block 18 to move through the T-shaped connecting rod 17. During the movement of the first hole block 18, the second hole block 21 can be driven to rotate around the frame rod 20 through the connecting sleeve 19. Because of the fixed installation effect of the connecting sleeve 19 and the frame rod 20, the frame rod 20 and the connecting sleeve 19 rotate at the same time. When the second hole block 21 rotates around the connecting sleeve 19, it will push the extrusion plate 24 in the connecting shaft 22 in the second hole block 21 to rotate. When the extrusion plate 24 rotates around the card interface 3, the operating plate body 1 will be clamped in the installation position as a whole through the thrust of the extrusion plate 24 extending outward, that is, the clamping installation of the operating plate body 1 is completed;

[0043] When the operating plate body 1 needs to be removed, it is only necessary to continue pressing the operating plate body 1. Because the wrapping pad 25 provided on the surface of the extrusion plate 24 of the operating plate body 1 is flexible, it has the ability to move downward and deform. When the operating plate body 1 is pressed downward, the position of the trapezoidal block 13 does not move. In this way, as the push plate 5 continues to move, the second card table 11 will be pushed to the position of the trapezoidal block 13. The second card table 11 moves on the inclined position of the trapezoidal block 13. Because the second card table 11 is limited by the limit ring 12, it will not move under the thrust of the push plate 5. In this way, the trapezoidal block 13 will move to the periphery of the second card table 11 accordingly. The second card table 11 is movably connected to the movable column 9. When the operator presses it, the second card table 11 can be in contact with the surface of the trapezoidal block 13. After that, the operator releases his hand and pushes the trapezoidal block 13 under the elastic force of the first spring 6 to drive the second card table 11 to move to the position of the first card table 10. The inclined surfaces of the first card table 10 and the second card table 11 are arranged oppositely. In this way, the trapezoidal block 13 will slide to the inclined surface of the first card table 10 and slide out through the inclined surface of the first card table 10, away from the first card table 10.

[0044] When the trapezoidal block 13 moves away from the first clamping platform 10, the push plate 5 will move in the opposite direction of the above-mentioned structure, thereby enabling the extrusion plate 24 to rotate in the opposite direction and be recovered into the clamping interface 3, thereby releasing the problem of the operating plate body 1 being squeezed and limited on the installation position, thereby ensuring the disassembly of the operating plate body 1. When the device pushes out the operating plate body 1, under the joint push of the return spring 30 and the first spring 6, the pressing cylinder 7 can push in the opposite direction, thereby increasing the convenience of removing the operating plate body 1.

[0045] The sealing barrier ring 8 and the wrapping pad 25 of the present device are both made of conductive rubber, because conductive rubber is a composite material made by uniformly dispersing conductive particles such as silver powder, copper powder, carbon fiber, etc. in a rubber matrix. The rubber itself is insulating, but after adding conductive particles, the conductive particles contact each other or form a conductive channel, so that the rubber has a certain conductivity. This characteristic is the basis for its ability to prevent electromagnetic interference, because good conductivity can enable electromagnetic energy to be conducted in the conductive rubber instead of radiating or reflecting to the surrounding space, and the annular sealing and conductive effect of the sealing barrier ring 8 can avoid the influence of electromagnetic on the operation of the device, and the operation is safe. The absorbing plate 31 arranged on the back of the plate body 1 utilizes its magnetic loss to absorb high-frequency electromagnetic interference signals, thereby reducing the impact on the touch display module. The absorbing plate 31 is a mesh structure with a spacing of 1mm-5mm between its openings. In this way, the low-frequency bands emitted by the operation plate body 1 will collide and absorb each other, thereby suppressing interference leakage and crosstalk. In addition, the surface of the operation plate body 1 is affixed with a composite shielding film composed of alternating metal layers and dielectric layers. The metal layer on this film can reflect electromagnetic waves, and the dielectric layer can absorb and refract electromagnetic waves, thereby achieving effective blocking of electromagnetic interference, thereby ensuring the anti-interference performance of the device.

[0046] The installation method, connection method or setting method disclosed in this embodiment are all common mechanical connection methods, and can be implemented as long as they can achieve their beneficial effects. In addition, the electrical components appearing in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Technicians in this field can control the electrical components through simple programming, and the existing disclosed power connection technology is also common knowledge in this field, so the specific structural composition and working principle will not be described in detail in this embodiment.
