The rotation of the driven gear 46 drives the fixedly connected driven shaft 47 to rotate, so that the two groups of first transmission wheels 49 fixedly connected to the driven shaft 47 rotate synchronously. When the first transmission wheel 49 rotates, the second transmission wheel 52 drives the synchronous rotation through the first transmission belt 51.

[0048] Further, the single-control component includes a first fixed seat 63 and a control structure, the bottom end of the first fixed seat 63 is fixedly connected to the inner wall of the second transmission chamber 48 near the front end, and the first fixed seat 63 is sleeved on the outer side of the shaft sleeve 42, the control structure is arranged at the front end of the base body 1, the front end of the first fixed seat 63 is fixedly connected to the rear end of the first spring 64, the front end of the first spring 64 abuts against the inner wall of the first extrusion seat 65, the first extrusion seat 65 is fixedly connected to the outer side of the shaft sleeve 42, and the second fixed seat 75 is fixedly connected to the inner wall of the second transmission chamber 48 near the rear end, the second fixed seat 75 is sleeved on the outer side of the active shaft 39, and the rear end of the second fixed seat 75 is fixedly connected to the front end of the fourth spring 76, the rear end of the fourth spring 76 abuts against the second extrusion seat 77, and the second extrusion seat 77 is fixedly connected to the outer side of the active shaft 39; the control structure includes a top block 66, the top block 66 is arranged at the center position of the front end of the base body 1, and the top block 66 The top of the top block 66 is provided with an inclined surface, and a U-shaped groove is provided at the center position of the top block 66. The bottom end of the rear side of the top block 66 is fixedly connected with a movable block 67. The movable block 67 is sleeved on the outer side of the second guide rod 68. The second guide rod 68 is fixedly connected to the inside of the movable groove 69, and a second spring 70 is wound around the outer side of the second guide rod 68. The movable groove 69 is provided at the center position of the front end of the base body 1. A clamping groove 71 is provided on the rear side of the movable block 67. The clamping groove 71 is engaged with the clamping block 72. The clamping block 72 is sleeved on the outer side of the third guide rod 73. The third guide rod 73 is fixedly connected to the top end of the inner wall of the movable groove 69. The outer side of the third guide rod 73 is also wound with a third spring 74; the top end of the second spring 70 is fixedly connected to the top end of the inner wall of the movable groove 69, the bottom end of the second spring 70 is fixedly connected to the top end of the movable block 67, the front end of the third spring 74 is fixedly connected to the clamping block 72, and the rear end of the third spring 74 is fixedly connected to the inner wall of the movable groove 69;

[0049] During operation, when only the lateral position of the touch panel 2 is to be adjusted, the top block 66 is first pushed upward so that the inclined surface on the top block 66 squeezes the shaft sleeve 42. When the top block 66 moves upward, the U-shaped groove in the middle thereof matches the diameter of the driving shaft 39, so that no interference occurs between the driving shaft 39 and the shaft sleeve 42 is only squeezed. In the process of the top block 66 moving upward, the movable block 67 fixedly connected thereto is driven to move synchronously inside the movable groove 69, and the second The spring 70 is squeezed to make the second spring 70 produce elastic deformation. When the top block 66 moves upward to the limit, the movable block 67 also moves to the limit inside the movable groove 69 synchronously. In the process of the movable block 67 moving upward to the limit, the slot 71 opened on the movable block 67 squeezes the bottom of the block 72. The block 72 moves backward when squeezed under the action of the inclined surface opened at the bottom thereof, and at the same time squeezes the third spring 74 to make the third spring 74 produce elastic deformation. After the movable block 67 moves upward to the limit, the slot 71 opens. The squeezing force of the card block 71 on the card block 72 disappears. At this time, the card block 72 automatically moves to its original position under the action of the restoring force of the third spring 74 and engages with the movable block 67 to fix the position of the top block 66. At the same time, the top block 66 also completely squeezes the part of the sleeve 42 protruding from the base body 1 into the interior of the base body 1 and maintains this state. In the process of the sleeve 42 moving toward the interior of the base body 1, the second slide groove 44 fixedly connected to the sleeve 42 moves synchronously to release the state of meshing with the active gear 45. At this time, when the knob 40 and the anti-slip sleeve 41 are rotated, the passive gear 46 will not be driven to rotate, and thus the touch panel 2 cannot be moved longitudinally. When the sleeve 42 moves, the second slider 43 fixedly connected to the sleeve 42 slides synchronously in the second slide groove 44. When the sleeve 42 moves, the first extrusion seat 65 fixedly connected to the sleeve 42 also moves synchronously with the movement of the sleeve 42, and at the same time, the first spring 64 is squeezed by the cooperation with the first fixed seat 63, so that the first spring 64 is elastically deformed.

[0050] Furthermore, a method for installing a heating, ventilation and air conditioning system comprises the following steps:

[0051] S1: Measure the dimensions of the bottom of the HVAC outdoor unit;

[0052] S2: Adjust the positions of the four sets of contact panels 2 by turning the knobs 40 and the anti-slip sleeves 41 according to the sizes, and adjust the contact panels 2 so that the inner wall is 3 cm away from the outer side of the bottom of the HVAC;

At the same time, the construction assistant pulls the HVAC outdoor unit to fine-tune the position to match the touch panel 2 to avoid collision between the bottom of the HVAC outdoor unit and the touch panel 2.

[0056] S6: After the outdoor unit of the HVAC is stably placed on the top surface of the touch panel 2, a structural adhesive is filled in the joint between the touch panel 2 and the outdoor unit of the HVAC;

[0073] S5: Turn the knob 40 and the anti-slip sleeve 41 again to adjust the position of the touch panel 2 so that the inner wall of the touch panel 2 is 1.5 cm away from the outer side of the bottom of the HVAC. At the same time, the construction assistant pulls the HVAC outdoor unit to fine-tune the position to match the touch panel 2 to avoid collision between the bottom of the HVAC outdoor unit and the touch panel 2.

[0074] S6: After the outdoor unit of the HVAC is stably placed on the top surface of the touch panel 2, a structural adhesive is filled in the joint between the touch panel 2 and the outdoor unit of the HVAC;

[0076] Working principle: When the longitudinal and lateral positions of the four groups of contact panels 2 are to be adjusted simultaneously, the anti-slip sleeve 41 and the knob 40 are first rotated to drive the fixedly connected active shaft 39 to rotate, the active shaft 39 rotates to drive the fixedly connected second bevel gear 38 to rotate, the second bevel gear 38 drives the meshing first bevel gear 37 to rotate, the first bevel gear 37 drives the first screw rod 35 to rotate, and the cooperation between the first screw rod 35 and the first screw sleeve 34 drives the two groups of contact panels 2 to move laterally, and when the first screw rod 35 rotates, the cooperation of the first pulley 57, the second transmission belt 58 and the second pulley 59 drives the third screw rod 60 to rotate synchronously, so that the third screw sleeve 61 threadedly connected to the outside of the third screw rod 60 drives the other two groups of contact panels 2 to move synchronously For lateral movement, the driving shaft 39 drives the sleeve 42 to rotate synchronously through the second slider 43 and the second slide groove 44 when rotating. The rotation of the sleeve 42 drives the driving gear 45 fixedly connected to its outer side to rotate. The driving gear 45 drives the meshing driven gear 46 to rotate. The rotation of the driven gear 46 drives the fixedly connected driven shaft 47 to rotate, so that the two groups of first transmission wheels 49 fixedly connected to the driven shaft 47 rotate synchronously. When the first transmission wheel 49 rotates, the second transmission wheel 52 drives the synchronous rotation through the first transmission belt 51. The rotation of the second transmission wheel 52 drives the fixedly connected second screw 50 to rotate, so that the second screw sleeve 53 threadedly connected to the second screw 50 moves, thereby driving the four groups of contact panels 2 to move longitudinally while moving horizontally.

[0077] When the touch panel 2 moves laterally, the third slider 54 fixedly connected to the top of the second screw sleeve 53 slides inside the third slide groove 56 to match the lateral movement of the touch panel 2. When the touch panel 2 moves longitudinally, the first slider 33 fixedly connected to the top of the first screw sleeve 34 slides inside the first slide groove 31 to match the longitudinal movement of the touch panel 2.

[0078] When only the longitudinal position of the touch panel 2 is to be adjusted, the knob 40 and the anti-slip sleeve 41 are first pulled away from the front end of the base body 1. Under the action of the pulling force, the knob 40 and the anti-slip sleeve 41 drive the active shaft 39 and the second bevel gear 38 to move synchronously. At this time, the second bevel gear 38 is released from the meshing state with the first bevel gear 37. When the active shaft 39 moves forward, it drives the second extrusion seat 77 fixedly connected to its outer side to move synchronously, so that the second extrusion seat 77 cooperates with the second fixed seat 75 to squeeze the fourth spring 76, thereby causing the fourth spring 76 to produce elastic deformation. At the same time, when the active shaft 39 moves forward, the second slider 43 also slides synchronously inside the second slide groove 44. Through the combined action of the second slider 43 and the second slide groove 44 The moving distance of the active shaft 39 is limited. When the knob 40 and the anti-slip sleeve 41 are pulled forward to the limit, the knob 40 and the anti-slip sleeve 41 are rotated to drive the shaft sleeve 42 to rotate through the second slider 43 and the second slide groove 44. The active gear 45 still rotates with the rotation of the shaft sleeve 42 and drives the meshing passive gear 46 to rotate synchronously, thereby achieving the effect of adjusting the longitudinal position of the touch panel 2; when it is necessary to restore the synchronous adjustment of the longitudinal and lateral movement of the touch panel 2, the knob 40 and the anti-slip sleeve 41 can be released. At this time, the active shaft 39 will automatically move to the original position under the action of the restoring force of the fourth spring 76, thereby restoring the meshing state between the second bevel gear 38 and the first bevel gear 37, and the longitudinal and lateral positions of the touch panel 2 can be adjusted at the same time.

[0079] When only the lateral position of the touch panel 2 is to be adjusted, the top block 66 is first pushed upward so that the inclined surface on the top block 66 squeezes the shaft sleeve 42. When the top block 66 moves upward, the U-shaped groove in the middle thereof matches the diameter of the driving shaft 39, so there is no interference with the driving shaft 39, and only the shaft sleeve 42 is squeezed. In the process of the top block 66 moving upward, the movable block 67 fixedly connected thereto is driven to move synchronously inside the movable groove 69, and squeezes the second spring 70 to cause the second spring 70 to produce elastic deformation. When the top block 66 moves upward to the limit, the movable block 67 is also synchronously in the movable groove 69 The inner part of the movable block 67 moves to the limit. In the process of the movable block 67 moving upward to the limit, the slot 71 provided on the movable block 67 squeezes the bottom of the block 72. The block 72 moves backward under the action of the inclined surface provided at the bottom thereof when squeezed, and at the same time squeezes the third spring 74 to cause the third spring 74 to produce elastic deformation. After the movable block 67 moves upward to the limit, the squeezing force of the slot 71 on the block 72 disappears. At this time, the block 72 automatically moves to its original position under the action of the restoring force of the third spring 74 and engages with the movable block 67 to fix the position of the top block 66. At the same time, the top block 66 also completely squeezes the part of the sleeve 42 protruding from the base body 1 into To the inside of the base body 1 and maintain this state. In the process of the shaft sleeve 42 moving toward the inside of the base body 1, the second sliding groove 44 fixedly connected to the shaft sleeve 42 moves synchronously to release the meshing state with the active gear 45. At this time, when the knob 40 and the anti-slip sleeve 41 are rotated, the passive gear 46 will not be driven to rotate, and thus the touch panel 2 cannot be moved longitudinally. When the shaft sleeve 42 moves, the second sliding block 43 fixedly connected to the shaft sleeve 42 slides synchronously in the second sliding groove 44. When the shaft sleeve 42 moves, the first extrusion seat 65 fixedly connected to the shaft sleeve 42 also moves synchronously with the movement of the shaft sleeve 42. At the same time, The first spring 64 is squeezed by the cooperation with the first fixed seat 63, so that the first spring 64 is elastically deformed; when it is necessary to restore the synchronous adjustment of the longitudinal and lateral movements of the touch panel 2, the card block 72 is pressed toward the base body 1 so that the card block 72 moves to release the engagement with the card slot 71. At this time, the movable block 67 automatically returns to its original position under the action of the restoring force of the second spring 70, and drives the top block 66 to return to its original position synchronously. At this time, the top block 66 releases the effect of squeezing the shaft sleeve 42, and the shaft sleeve 42 also returns to its original position under the action of the restoring force of the first spring 64. At this time, the longitudinal position and lateral position of the touch panel 2 can be adjusted synchronously.
