Description

Technical Field

[0001] This utility model relates to the field of touch screen technology, specifically to a large touch screen structure. Background Technology

[0002] A touchscreen, also known as a touch panel or touch screen, is a sensor-type liquid crystal display device that can receive input signals from touch. When a graphic button on the screen is touched, the tactile feedback system on the screen can drive various connected devices according to a pre-programmed program. It can replace mechanical button panels and create vivid audio-visual effects through the liquid crystal display. A touchscreen is an input device that enables human-computer interaction by directly touching the screen surface with a finger or stylus. It is widely used in electronic devices such as smartphones, tablets, and ATMs. When a large touchscreen is required, multiple touchscreen modules are often mounted on a support frame to form a large, integrated touchscreen.

[0003] However, existing touchscreen modules are tightly packed on the support frame, making installation and removal of the touchscreen modules inconvenient. This solution addresses this technical problem. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a large touchscreen structure. The touchscreen module is attracted and fixed to the support plate by the magnetic force of magnets one and two, making touchscreen installation convenient and quick. Positioning grooves are used to position the positioning platform, ensuring more precise installation of the touchscreen display within the support frame. Rotating the operating knob allows pin one to be inserted into the spiral groove to further lock magnet one, thus making the touchscreen module more securely fixed. Installation of the touchscreen module can be achieved without manually pressing the touchscreen display, ensuring safe and reliable installation.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a large touch screen structure, including a support frame, and a plurality of touch screen modules arrayed on the support frame. A base plate and a support plate are respectively provided on the inner side of the support frame. Locking components corresponding to the touch screen modules are arrayed on the base plate. The touch screen module includes an isolation plate, a locking hole provided on one side of the isolation plate, and a touch display screen provided on the other side of the isolation plate. A plurality of positioning platforms are provided on the other side of the isolation plate. A positioning groove for accommodating the positioning platforms is provided on the support plate. The locking components pass through the support plate and are detachably connected to the locking hole.

[0006] A magnet is provided on one side of the isolation plate, and a magnet is provided on the locking assembly. The magnet and the magnet can be detachably attracted together.

[0007] The inner side of the locking hole is provided with a spiral groove. The locking assembly includes a connecting rod movably disposed on the base plate and a pin at one end of the connecting rod. The pin is detachably connected to the spiral groove. The other end of the connecting rod is provided with an operating knob.

[0008] The locking hole is located inside the first magnet, and the second magnet is movably sleeved on the outside of the connecting rod. An arc-shaped groove is provided on the inner side of the second magnet, and a second pin is provided on the side of the connecting rod to drive the second magnet to rotate. The second pin is oscillating within the arc-shaped groove. The second pin drives the second magnet to rotate 180°, causing the magnetic poles to reverse.

[0009] The base plate is provided with a positioning post, and the two ends of the magnet are provided with protrusions, and the two protrusions are respectively separably abutted against the positioning post.

[0010] The positioning platform is a truncated quadrangular shape, the positioning groove has the same shape as the positioning platform, the cross-section of the positioning platform is rectangular, and both magnet one and magnet two are rectangular.

[0011] Several connecting columns are provided to support the base plate and the support plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The touch screen module is attracted and fixed to the tray by the magnetic force of magnet one and magnet two. The installation of the touch screen is convenient and quick. The positioning slot is used to position the positioning platform, so that the touch screen is installed more accurately in the carrier frame. By rotating the operation knob, the pin one is inserted into the spiral groove to further lock magnet one, so that the touch screen module is more firmly fixed. The installation of the touch screen module can be achieved without manually pressing the touch screen. The installation of the touch screen module is safe and reliable.

[0014] (2) By rotating the control knob in the opposite direction, the connecting rod is driven to rotate, thereby separating the pin rod one from the spiral groove. Further rotating the connecting rod, the pin rod two drives the magnet two to rotate to the opposite pole, generating a repulsive force with the magnet one, thereby pushing the touch screen module on the isolation plate out and separating it from the tray. The disassembly of the touch screen module is convenient and quick.

[0015] (3) By setting both the positioning platform and the positioning slot asymmetrically, the design can prevent errors in the installation direction of the touch screen module. Attached Figure Description

[0025] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0026] See Figures 1-8 A large touch screen structure includes a support frame 1 and a plurality of touch screen modules 2 arrayed on the support frame 1. A base plate 3 and a support plate 4 are respectively provided on the inner side of the support frame 1. Locking components 5 corresponding to the touch screen modules 2 are arrayed on the base plate 3. The touch screen module 2 includes an isolation plate 21, a locking hole 22 provided on one side of the isolation plate 21, and a touch display screen 23 provided on the other side of the isolation plate 21. A plurality of positioning stages 24 are provided on the other side of the isolation plate 21. The support plate 4 is provided with a positioning groove 41 for accommodating the positioning stages 24. The locking components 5 pass through the support plate 4 and are detachably connected to the locking hole 22.

[0027] A magnet 25 is provided on one side of the isolation plate 21, and a magnet 54 is provided on the locking component 5. The magnet 25 and the magnet 54 can be detachably attracted together. The isolation plate 21 is made of magnetic shielding material. By setting the isolation plate 21, the touch screen 23 is supported and the magnetic fields of the magnet 25 and the magnet 54 are isolated to avoid interference from the magnetic field to the touch screen.

[0028] The inner side of the locking hole 22 is provided with a spiral groove 221. The locking assembly 5 includes a connecting rod 52 movably disposed on the base plate 3 and a pin 521 disposed at one end of the connecting rod 52. The pin 521 is detachably connected to the spiral groove 221. The other end of the connecting rod 52 is provided with an operating knob 522.

[0029] The locking hole 22 is located inside the first magnet 25. The second magnet 54 is movably sleeved on the outside of the connecting rod 52. The inner side of the second magnet 54 is provided with an arc-shaped groove 541. The side of the connecting rod 52 is provided with a pin 523 for driving the second magnet 54 to rotate. The pin 523 is oscillatingly located in the arc-shaped groove 541. The pin 523 drives the second magnet 54 to rotate 180° to reverse the magnetic poles.

[0030] The base plate 3 is provided with a positioning post 31, and the two ends of the magnet 54 are provided with protrusions 542, which are detachably abutted against the positioning post 31.

[0031] The positioning platform 24 is a truncated quadrangular shape, and the positioning groove 41 has the same shape as the positioning platform 24. The cross-section of the positioning platform 24 is rectangular. Magnet 1 25 and Magnet 2 54 are both rectangular. The positioning platform 24 and the positioning groove 41 are asymmetrically arranged, which has the effect of foolproof design and avoids the phenomenon of incorrect installation direction of the touch screen module 2.

[0032] Several connecting columns 6 are provided between the base plate 3 and the support plate 4.

[0033] The base plate 3 is provided with a reset mark 32, a lock mark 33 and an unlock mark 34 near the operation knob 522.

[0034] The specific working process of this utility model:

[0035] When the touch screen module 2 needs to be installed, turn the operation knob 522 to the reset mark 32, align the positioning platform 24 of the isolation plate 21 with and insert it into the positioning groove 41 of the tray 4. At this time, the magnet 25 on the isolation plate 21 and the magnet 54 of the locking assembly 5 attract each other, further attracting and fixing the touch screen module 2 into the positioning groove 41. At this time, the pin 521 is inserted into the spiral groove 221. Rotate the operation knob 522 to the locking mark 33, and the pin 523 moves in the arc groove 541 of the magnet 54. Finally, the pin 521 is inserted into the spiral groove 221. The bottom of the base plate 4 is then used to further lock the magnet 25 to the pin 521 of the locking assembly 5, thus completing the installation of the touch screen module 2. The touch screen module 2 is provided with elastic pins, and the base plate 3 is provided with contacts. When the touch screen module 2 is installed on the support plate 4, the elastic pins on the touch screen module 2 contact the contacts on the base plate 3. The base plate 3 is provided with a controller, and several contacts are electrically connected to the controller, thereby realizing the controller's control of the touch display screen 23 on multiple touch screen modules 2. The connection between the touch screen and the controller is achieved using existing technology, which will not be described in detail here.

[0036] When it is necessary to disassemble the touch screen module 2, rotate the operation knob 522 in the opposite direction. When the pin 523 of the operation knob 522 swings in the arc groove 541 of the magnet 54 to the reset mark 32, the pin 521 disengages from the spiral groove 221 of the locking hole 22. Continue to rotate the operation knob 522. The pin 523 drives the magnet 54 to rotate along the connecting rod 52. When the operation knob 522 is rotated to the unlock mark 34, the boss 542 at the other end of the magnet 54 contacts the positioning post 31. The two poles of the magnet 54 reverse 180 degrees. At this time, the magnet 54 and the magnet 25 generate a repulsive force. The repulsive force repels the touch screen module 2 to detach from the support frame 1, thereby completing the disassembly of the touch screen module 2.

[0037] The touch screen module 2 is attracted and fixed to the support plate 4 by the magnetic force of magnet 25 and magnet 54. The installation of the touch screen is convenient and quick. The positioning groove 41 positions the positioning platform 24, so that the touch screen display 23 is installed more accurately in the support frame 1. By rotating the operation knob 522, the pin 521 is inserted into the spiral groove 221 to further lock the magnet 25, so that the touch screen module 2 is fixed more firmly. The installation of the touch screen module 2 can be achieved without manually pressing the touch screen display 23. The installation of the touch screen module 2 is safe and reliable.

[0038] By rotating the control knob 522 in the opposite direction, the connecting rod 52 is driven to rotate, thereby separating the pin 521 from the spiral groove 221. Further rotating the connecting rod 52, the pin 523 drives the magnet 54 to rotate to the opposite pole, generating a repulsive force with the magnet 25, thereby pushing the touch screen module 2 on the isolation plate 21 out and separating it from the tray 4. The disassembly of the touch screen module 2 is convenient and quick.

[0039] By setting both the positioning platform 24 and the positioning slot 41 asymmetrically, a foolproof design is implemented, which avoids incorrect installation orientation of the touch screen module 2.

[0040] Technical features not described in detail in this solution are based on conventional operations and general understanding of those skilled in the art, and are therefore not elaborated upon here. Technical features not described in this utility model can be implemented using existing technology, and will not be repeated here. Of course, the above description is not intended to limit this utility model, nor is it limited to the examples given above. Any changes, modifications, additions, or substitutions made by those skilled in the art within the scope of this utility model should also fall within the protection scope of this utility model.
