DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] The utility model provides Figure 1-3 The knob central control screen shown includes a power base box 1 and a panel 2 arranged on the front of the power base box 1, a display component 3 is arranged on the front of the power base box 1, and a fixing component 4 for fixing the position of the panel 2 is arranged at the connection between the power base box 1 and the panel 2; the fixing component 4 includes a card slot 401 opened at the top of the panel 2, a limiting block 402 is clamped inside the card slot 401, and an elastic block 403 is fixedly connected to the bottom end of the limiting block 402, a fixing slot 404 for accommodating the limiting block 402 and the elastic block 403 is opened at the top of the power base box 1, a limiting member for limiting the moving direction of the limiting block 402 is arranged in the middle of the limiting block 402, a pressing slot 405 is opened at the top of the limiting block 402, and a sliding slot 406 is opened on the inner wall of the back of the card slot 401.

[0020] It should be noted that a power module is arranged inside the power base box 1, and power is supplied to the display component through the power module, and the panel 2 is made of plastic; holes for bolts to pass through are provided on both sides of the power base box 1, and when the power base box 1 needs to be installed, the power base box 1 is first inserted into the 86 power box, and then the bolts are passed through the holes on the power base box 1, and the power base box 1 is fixed in the 86 power box; a circular hole for the display component 3 to pass through is provided in the middle of the panel 2; the cross-sections of the limiting block 402, the card slot 401 and the fixed slot 404 are all set to be square, so that the limiting block 402 cannot rotate inside the fixed slot 404 while sliding inside the fixed slot 404; the pressing slot 405 provided at the top of the limiting block 402 is used for the card pin , toothpicks or other objects are inserted into the pressing groove 405. When in use, the limiting block 402 is pushed downward by a sharp object, so that the limiting block 402 is moved into the interior of the fixing groove 404. When moving the panel 2, the sharp object passes through the sliding groove 406 on one side of the card slot 401 to avoid the situation where the panel 2 is blocked by objects and cannot move; the elastic block 403 is set to be made of rubber material, and the rubber material has the characteristic of deformation. When the limiting block 402 moves to one side of the elastic block 403, the elastic block 403 is squeezed and deformed. When the limiting block 402 loses the squeezing force, it will restore the deformation and push the limiting block 402 to the side away from the elastic block 403. The set elastic block 403 is fixed to the inner wall of the bottom end of the fixing groove 404 by bonding.

[0021] Specifically, the limiting member includes a through hole 407 opened in the middle of the limiting block 402, and a limiting rod 408 is inserted and connected inside the through hole 407. The two sides of the limiting rod 408 are respectively inserted and connected to the inner walls on both sides of the fixing groove 404, and the limiting rod 408 is fixedly connected to the back of the panel 2.

[0022] It should be noted that a through hole is provided on the inner wall of one side of the fixing groove 404, and a limiting groove is provided on the inner wall of the other side. When the panel 2 is moved to one side of the power base box 1 and fixed, the limiting rod 408 is driven by the panel 2 to move to one side of the power base box 1, and the limiting rod 408 is driven by the panel 2 to pass through the through hole, the perforation 407 and the limiting groove in sequence, so that both sides of the limiting rod 408 are restricted by the panel 2, the through hole and the limiting groove, so that it cannot move upward. During use, after the panel 2 moves to the desired position, the downward pressing of the limiting block 402 is released, and the limiting block 408 is moved downward. 02 is driven by the elastic block 403 to recover its deformation and move upward. When the limiting block 402 moves to the point where the inner wall of the bottom end of the through hole 407 opened in the middle thereof fits with the bottom end of the limiting rod 408, the limiting rod 408 will limit the limiting block 402 and prevent it from continuing to move upward, thereby fixing the position of the limiting block 402. The fit between the bottom of the limiting rod 408 and the inner wall of the bottom end of the through hole 407 can avoid the situation where the elastic block 403 drives the limiting block 402 to directly move out of the fixing groove 404 after the separation between the elastic block 403 and the fixing groove 404, thereby strengthening the fixation of the position of the panel 2.

[0023] Specifically, a magnetic fixing iron plate 5 is provided on the front of the power base box 1, a circuit board mounting plate 6 is provided on the front of the magnetic fixing iron plate 5, the magnetic fixing iron plate 5 and the circuit board mounting plate 6 are both inserted and connected on the back of the panel 2, a plastic ejector positioning piece 11 is provided on the front of the magnetic fixing iron plate 5, and the display component 3 includes a light-transmitting ring 301 arranged on the front of the circuit board mounting plate 6, a knob mechanism connecting piece 302 is provided on the front of the light-transmitting ring 301, a bracket 303 is provided on the front of the knob mechanism connecting piece 302, a display screen 304 is provided on the front of the bracket 303, the outer wall of the display screen 304 is sleeved with a knob sheet metal part 305, a flexible card block 7 is symmetrically provided on the outer wall of the knob mechanism connecting piece 302, a positioning groove 8 is symmetrically opened on the inner wall of the knob sheet metal part 305, and the flexible card block 7 is clamped inside the positioning groove 8.

[0024] It should be noted that the knob sheet metal part 305 is used to adjust the display screen 304 clockwise or counterclockwise, the display screen 304 is a TFT screen display, and the plastic ejector positioning part 11 is used to fix the power supply ejector to prevent short circuit; a magnet is provided on the back of the circuit board mounting plate 6, which is fixed to the front side of the magnetic fixing iron plate 5 by magnetic attraction, and the position of the circuit board mounting plate 6 is adjusted by magnetic attraction.

[0025] Furthermore, when assembling it, first fix the magnetic fixing iron plate 5 to the front of the power base box 1 by bolts, then fix the circuit board mounting plate 6 to the magnetic fixing iron plate 5 by magnetic attraction, fix the light-transmitting ring 301 to the front of the circuit board mounting plate 6 by bonding, insert the knob mechanism connector 302 into the front of the light-transmitting ring 301, then place the display screen 304 on the front of the bracket 303, and insert the bracket 303 together with the display screen 304 into the knob sheet metal part 30 5, and finally move the knob sheet metal 305 toward the knob mechanism connecting part 302, so that the knob sheet metal 305 is sleeved on the front side of the knob mechanism connecting part 302, and the flexible clamp block 7 is squeezed and deformed by the extrusion of the knob sheet metal 305. When the positioning groove 8 on the knob sheet metal 305 is aligned with the flexible clamp block 7, the flexible clamp block 7 recovers its deformation and moves into the positioning groove 8, and the knob sheet metal 305 is fixed to the front side of the knob mechanism connecting part 302 by the flexible clamp block 7.
