DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0024] Embodiment: please refer to Figures 1-5 The utility model provides a technical scheme: a flexible control structure of touch switch, including shell, both sides of the shell are fixedly connected with wrist strap, the top of the shell is connected with cover plate, the inboard of the cover plate is fixedly connected with touch screen, the bottom of the touch screen is inserted with wire, the inboard of the shell is movably installed with circuit board, one end of the wire away from the touch screen is inserted with the outside of circuit board, the periphery of the circuit board is slidably connected with the outside of limiting mechanism through mounting hole, the limiting mechanism has four, and is located at the four corners of the shell respectively, this structure is mainly applied to wearable equipment, and is worn on the wrist through wrist strap. User operates through touch screen, and touch screen transmits signal to circuit board for processing through wire. Limiting mechanism is used for limiting and fixing circuit board, guarantees its stable work in shell, and cover plate is connected in the top of shell, plays the role of protecting internal structure.

[0025] It also includes: a limiting mechanism, the bottom of which is fixedly connected to the inner side of the outer shell. The limiting mechanism includes a hollow guide post, a threaded rod rotatably connected to the inner side of the hollow guide post, a limiting slide plate threadedly connected to the outer wall of the threaded rod, a pressing block slidably connected to the bottom of the limiting slide plate, a movable rod rotatably connected to the bottom of the pressing block, a sliding rod rotatably connected to the bottom end of the movable rod, a tension spring fixedly connected to the outer side of the sliding rod, the bottom of the hollow guide post fixedly connected to the inner side of the outer shell, the outer wall of the hollow guide post slidably connected to the inner wall of the circuit board through mounting holes, the side wall of the limiting slide plate slidably connected to the inner wall of the hollow guide post, the inner wall of the limiting slide plate slidably connected to the outer wall of the sliding rod, a support bolt threadedly connected to the bottom of the sliding rod, a guide rod slidably connected to the top of the sliding rod, the bottom of the guide rod fixedly connected to the top of the limiting slide plate, and the top of the limiting slide plate fixedly connected to the bottom end of the tension spring. When installing the circuit board, the cover plate is removed from the outer shell, and then the four mounting holes of the circuit board are... Align the hollow guide post with the four limiting mechanisms. Rotate the threaded rod to allow the limiting slide plate to slide downwards along the inner side of the hollow guide post. When the support bolt reaches its lower stop, the sliding rod slides relative to the limiting slide plate as the limiting slide plate continues to move. This causes the pressing block to be pushed outwards via the movable rod, stretching the tension spring. During this process, the guide rod guides the sliding rod's movement, while the pressing block, pushed outwards, gradually presses against the circuit board surface as the hollow guide post moves, thus fixing the circuit board and ensuring it won't easily shift or loosen, guaranteeing the stability and reliability of the equipment. The support bolt, when rotated, allows it to slide up and down along the central axis of the sliding rod, adjusting its initial height and thus changing the initial state of the limiting mechanism. When installing circuit boards of different thicknesses, rotating the support bolt allows the sliding rod's position to be adjusted in advance, enabling the limiting mechanism to better fit the circuit board and ensuring the pressing block accurately presses against the circuit board surface for a secure fixation.

[0026] In use, this structure is primarily applied to wearable devices, worn on the wrist via wristband 2. Users operate the device through touchscreen 4, which transmits signals to circuit board 6 for processing via ribbon cable 7. A limiting mechanism 5 is used to limit and fix circuit board 6, ensuring its stable operation within the housing 1. Cover plate 3 is snapped onto the top of housing 1, protecting the internal structure.

[0027] When installing the circuit board 6, the cover plate 3 is detached from the shell 1, and then the four mounting holes of the circuit board 6 are placed against the hollow guide columns 51 in the four limiting mechanisms 5, at this time the threaded rods 52 are rotated, so that the limiting sliding plates 53 slide downwards along the inner sides of the hollow guide columns 51, when the supporting bolts 57 run to the lower limit points, with the continuous displacement of the limiting sliding plates 53, at this time the sliding rods 56 slide relative to the limiting sliding plates 53, and the movable rods 55 push the pressing blocks 54 outwards, at this time the tension springs 59 are stretched under force;

[0028] In this process, the guide rods 58 guide the sliding of the sliding rods 56, and the pressing blocks 54 pushed outwards are gradually pressed against the surface of the circuit board 6 with the movement of the hollow guide columns 51, so that the circuit board 6 can be fixed, and the stability and reliability of the equipment are ensured.

[0029] Among them, by setting the supporting bolt 57, when rotating the supporting bolt 57, the supporting bolt 57 can slide up and down along the central axis of the sliding rod 56, and then the initial height of the bottom part, so as to change the initial state of the limiting mechanism 5, when installing circuit boards 6 of different thicknesses, by rotating the supporting bolt 57 to adjust the position of the sliding rod 56 in advance, the limiting mechanism 5 can better adapt to the circuit board 6, and ensure that the pressing block 54 can be accurately pressed against the surface of the circuit board 6, and stable fixation is realized.
