[0015] This utility model has the following beneficial effects:

[0016] This utility model features two detachable symmetrical folding functional panel frames and functional panels. In use, the folding functional panel frames are opened to the horizontal and pushed inward to merge the two functional panel frames. Each functional panel is rotated to the desired side via a pivot. Pushing the two functional panels causes the pivot to slide within the sliding key to the appropriate position, allowing the two functional panels to merge into a single functional panel via the convex keys and shallow grooves on the sides. Rotating the bolts on both sides of the functional panel frame causes the bolts to drive the push plate to rotate inward. The push plate pushes the plate, which is fixed in place by a spring component, inward, so that the surface of the plate contacts the surface of the functional panel, causing the functional panel to press inward and tightly fit together, thus fixing the functional panel in the horizontal direction.

[0017] This invention cleans the functional board by creating a threaded groove on the top of the functional board frame and installing a threaded rod. A motor is installed on the outer surface of the functional board frame and connected to the threaded rod. The motor drives the threaded rod to rotate, and the rotation of the threaded rod with the threaded groove on the inner wall of the boss causes the support platform connected to the boss to slide horizontally on the top of the functional board frame. The support platform is connected to a pressure block via a connecting rod, which causes the board cleaning strip, which is engaged with the pressure block, to slide horizontally on the surface of the functional board under the action of the pressure block and the long strip, thereby achieving the effect of cleaning the functional board.

[0018] This invention features a fixed connecting block on the outer surface of the support frame base plate, allowing the rotatable bracket connected by a long shaft to rotate vertically. When the rotatable bracket rotates to the bottom, a connecting rod on the inner surface of the rotatable bracket drives the trapezoidal frustum into the cylindrical groove, causing the spring catch to engage with the lower surface of the trapezoidal frustum, thus fixing the rotatable bracket vertically. When the rotatable bracket needs to be flipped upwards, it is pushed inwards, causing the connecting rod to slide the slidable inverted trapezoidal frustum upwards. This causes the spring catch to slide from the upper surface of the inverted trapezoidal frustum to the lower surface, merging the inverted trapezoidal frustum with the trapezoidal frustum. The spring catch then slides from the lower surface of the inverted trapezoidal frustum to the upper surface of the trapezoidal frustum, pulling the rotatable bracket outwards to finally disengage.

[0019] This invention features two sets of rotating brackets with fixed boss feet and fixed groove feet at their bottoms. When not in use, the buckles on the bottom of the fixed boss feet are released by pressing the buckles on both sides inward, allowing the buckles to return to their original positions. The rotating bracket is then flipped above the functional board frame, causing the buckles on the fixed boss feet to press against the pressing slider on the fixed groove feet. The pressing slider slides downward, pushing the parallel slider to the left, which in turn pushes the vertical slider upward. The vertical slider then pushes the limit slider to the right, restricting the up-and-down movement of the buckles. In use, pressing the buckles tightens them, and the buckles no longer press against the pressing slider. Under the action of the helical spring, the limit slider is pulled back, pushing the vertical slider downward. The vertical slider then pushes the parallel slider to the right, and the parallel slider pushes the pressing slider upward, completing the reset.

[0044] In use, two detachable symmetrical folding functional panel frames 1 and functional panel 2 are configured. When in use, the folding functional panel frame 1 is opened to a horizontal position and pushed inwards to merge the two functional panel frames 1. Each functional panel 2 is rotated to the desired side via the pivot 12. Pushing the two functional panels 2 causes the pivot 12 to slide within the keyway 13 to the appropriate position, allowing the two functional panels 2 to merge into a single functional panel via the side protrusions 15 and shallow grooves 14. Rotating the bolts 11 on both sides of the functional panel frame 1 causes the push plate 18 to rotate inwards. The push plate 18 pushes the plate 16, which is fixed by a spring component 19, inwards, causing the surface of plate 16 to contact the surface of functional panel 2, thus pressing functional panel 2 inwards and tightly fitting the two functional panels 2 together. The functional plate 2 is fixed horizontally. A threaded rod 21 is installed by opening a threaded groove 17 on the top of the functional plate frame 1. A motor 22 is installed on the outer surface of the functional plate frame 1 and connected to the threaded rod 21. The motor 22 drives the threaded rod 21 to rotate. The threaded rod 21 rotates with the threaded groove 29 on the inner wall of the boss 28, causing the support platform 23 connected to the boss 28 to slide horizontally on the top of the functional plate frame 1. The support platform 23 is connected to the pressure block 26 through the connecting rod 25. Under the action of the pressure block 26 and the long strip 30, the plate cleaning strip 24, which is engaged with the pressure block 26, slides horizontally on the surface of the functional plate 2 to achieve the effect of cleaning the functional plate. The support frame base plate 31 is fixed on the outer surface. The connecting block 32 allows the rotatable bracket 49, connected by the long shaft 33, to rotate vertically. When the rotatable bracket 49 rotates to the lower position, the connecting rod 36 on the inner surface of the rotatable bracket 49 drives the trapezoidal frustum 41 into the cylindrical groove 37, causing the spring catch 38 to engage with the lower surface of the trapezoidal frustum 41, thus fixing the rotatable bracket 49 vertically. When the rotatable bracket 49 needs to be flipped upwards, pushing the rotatable bracket 49 inwards causes the connecting rod 36 to drive the slidable inverted trapezoidal frustum 39 upwards, causing the spring catch 38 to slide from the upper surface to the lower surface of the inverted trapezoidal frustum 39, merging the inverted trapezoidal frustum 39 with the trapezoidal frustum 41, and causing the spring catch 38 to slide from the lower surface of the inverted trapezoidal frustum 39 to the upper surface of the trapezoidal frustum 41. Pull the flip bracket 49 outward to finally disengage. By setting fixed boss feet 50 and fixed groove feet 70 at the bottom of the two sets of flip brackets 49 respectively, when not in use, the buckle 55 at the bottom of the buckle plate 54 on the fixed boss feet 50 is released by squeezing the buckle plates 54 on both sides inward to release the buckle 55, so that the buckle plate 54 returns to its original position. Flip the flip bracket 49 to the top of the functional board frame 1, so that the buckle plate 54 of the fixed boss feet 50 squeezes the pressing slider 60 on the fixed groove feet 70. The pressing slider 60 slides down, pushing the parallel slider 56 to move to the left. The parallel slider 56 pushes the vertical slider 57 to move upward. The vertical slider 57 pushes the limiting slider 58 to move to the right, restricting the up and down movement of the buckle plate 54.In use, squeezing the buckle plate 54 causes the buckle 55 to lock in place. The buckle plate 54 no longer squeezes the pressing slider 60. Under the action of the spiral spring 62, the limiting slider 58 is pulled back, pushing the vertical slider 57 downward. The vertical slider 57 pushes the parallel slider 56 to move to the right. The parallel slider 56 pushes the pressing slider 60 upward, completing the reset.
