[0002] A touch screen all-in-one machine is a touch screen all-in-one device designed for easy maintenance and disassembly. It usually adopts a snap-on or screw-fixed design, making it easy to assemble and disassemble. It is commonly found in self-service terminals, digital signage, and information query systems.

[0003] A search revealed that CN203909756U discloses a front-detachable touchscreen all-in-one machine. The touchscreen is mounted in a mounting slot within the casing via a fixing frame. Several grooves are provided along the horizontal and vertical directions on the outer edge of the casing. Several hooks, which mate with the grooves, are provided on the inner edge of the fixing frame that engages with the casing. The grooves on the casing and the hooks on the fixing frame are pressed together, and the hooks on the fixing frame are made of plastic and can be elastically pressed into the grooves. An arc-shaped slit is provided on the lower edge of the fixing frame to facilitate disassembly from the casing, allowing for easy removal of the touchscreen for inspection of the internal wiring. Several arc-shaped ventilation holes are provided horizontally on the lower surface of the casing near the fixing plate to improve the heat dissipation of the all-in-one machine.

[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] This application discloses a front-detachable touchscreen all-in-one machine. (Refer to...) Figures 1 to 6 The front-detachable touch screen all-in-one machine includes a touch screen 1, a body cover 2, a fixing frame 3, an insert knob 4, a rotation positioning component 5, and a snap-fit ​​component 6. The touch screen 1 is snapped onto the outside of the body cover 2. The surface of the fixing frame 3 is tightly fitted to the side of the body cover 2 away from the touch screen 1. The insert knob 4 is inserted into the outside of the body cover 2. The rotation positioning component 5 is installed on the inside of the body cover 2. The snap-fit ​​component 6 is installed on the inside of the fixing frame 3. Touch screen 1 is used for finger touch voltage, body cover 2 is used to connect touch screen 1 and fixed frame 3, fixed frame 3 is used to connect snap-fit ​​component 6, insert knob 4 works with rotation positioning component 5 to connect and disconnect snap-fit ​​component 6 by flexibly rotating inside body cover 2, snap-fit ​​component 6 is used to directly connect to fixed frame 3 and can control the on / off of fixed frame 3 and body cover 2.

[0027] Push the touchscreen 1 and the housing 2 assembly back along the guide rail. A "click" sound indicates that the ball 63 has entered the pre-positioned circular groove 7. Rotate the insertion knob 4 counterclockwise to the initial position. The square locking block 55 pushes the connecting plate 62 with the inner groove to generate a clamping force, so that the sealing gasket 9 after docking is compressed to the specified thickness.

[0028] The rotary positioning assembly 5 includes a push shaft 51, a circular sleeve 52, a hollow positioning ring 53, a limiting strip with a raised edge 54, and a square locking block 55. The push shaft 51 is fixedly connected to the outside of the insert-type knob 4. The circular sleeve 52 is fixedly connected to the inner side of the body cover 2. The hollow positioning ring 53 is rotatably connected to the inner side of the circular sleeve 52. The limiting strip with a raised edge 54 is fixedly connected to the outside of the hollow positioning ring 53. One end surface of the square locking block 55 is fixedly connected to the outside of the push shaft 51.

[0029] The circular sleeve 52 ensures axial concentricity, the square groove 8 of the hollow positioning ring 53 constrains the movement trajectory of the square locking block 55, and the convex edge limiting strip 54 limits the rotation angle range, so that the convex edge limiting strip 54 can stably dock with the protrusions 61 at both ends of the inner groove connecting plate 62.

[0030] The snap-fit ​​assembly 6 includes a protrusion 61, a connecting plate 62 with an inner groove, a snap ball 63, and a compression spring 64. The protrusion 61 is fixedly connected to both sides of the connecting plate 62 with an inner groove and is used to abut against the limiting strip 54 with a protruding edge. The inner side of the groove of the connecting plate 62 with an inner groove is slidably connected to the surface of the square snap block 55. The snap ball 63 is movably connected to the inner side of the connecting plate 62 with an inner groove and is used to abut against the square snap block 55. The two sides of the compression spring 64 are fixedly connected to the surface of the snap ball 63 and the connecting plate 62 with an inner groove, respectively.

[0031] The retaining ball 63 generates positive pressure under the action of the compression spring 64, and the chamfered design of the circular groove 7 achieves self-centering. Stability is maintained in a vibration environment through the three-point contact of the retaining ball 63 and the two sets of protrusions 61.

[0032] The inside of the square card block 55 has a circular groove 7 that matches the size of the card ball 63.

[0033] The hollow positioning ring 53 also has a square groove 8 in the middle, which is the same size as the square card block 55. When not fully unlocked, the convex edge limiting strip 54 will prevent the module from separating.

[0034] A sealing gasket 9 is also adhesively connected to the connection between the touch screen 1 and the body cover 2, forming an IP54 protection rating.

[0035] The usage process of the front-detachable touchscreen all-in-one machine according to this application embodiment is roughly as follows: During the opening process, the maintenance personnel hold the insert knob 4 from the outside of the casing 2 and rotate it 90° clockwise. The rotational torque is transmitted to the square locking block 55 through the push shaft 51, and the square locking block 55 makes linear displacement within the square groove 8. The retraction of the square locking block 55 causes the connecting plate 62 with the inner groove to move, and the locking ball 63 disengages from the circular groove 7 under the action of the compression spring 64, and the protrusion 61 separates from the limiting strip 54 with the protruding edge. At this time, the touch screen 1 and the casing 2 can be moved forward and removed as a whole module. The sealing gasket 9 generates initial separation resistance and provides a seal between the casing 2 and the fixing frame 3 during docking.

[0036] The beneficial technical effects of the front-detachable touchscreen all-in-one machine according to the embodiments of this application are roughly as follows: The rotary positioning component 5 and the snap-fit ​​component 6 of this device form a mechanical interlock. The push shaft 51 is pushed and rotated by the insert knob 4. With the torque conversion of the square snap-fit ​​block 55, the precise conversion from rotary motion to linear motion is achieved. The circular sleeve 52 provides axial positioning, the hollow positioning ring 53 ensures radial accuracy, and the convex edge limit strip realizes the angle. The snap-fit ​​ball 63 and the compression spring 64 elastically connect the square snap-fit ​​block 55 to achieve a flexible on / off effect. This allows the device to be opened and closed by simply operating the insert knob 4 on the front panel. Maintenance personnel do not need special tools.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
