[0027] See also Figure 1-8As shown, a positioning and debugging device for a central air conditioner comprises a support plate 1, a support plate 2, a bottom plate 10 and an air-conditioning outdoor unit 17. Support frames 18 are bolted to both sides of the bottom of the air-conditioning outdoor unit 17. The support frames 18 can provide support for the air-conditioning outdoor unit 17 to keep it away from the ground. The top of the support plate 1 is provided with anti-slip patterns to enhance the friction when in contact with the air-conditioning outdoor unit 17. Horizontal rails 3 are bolted to both sides of the bottom of the support plate 1. The support plate 2 is located between the support plate 1 and the bottom plate 10. Vertical rails 4 are bolted to both sides of the top of the support plate 2. The two horizontal rails 3 and the two vertical rails 4 are arranged in an interlaced manner. Sliding blocks 5 are arranged at the intersections of the two horizontal rails 3 and the two vertical rails 4. The top of the sliding block 5 is slidably connected to the horizontal rail 3, and the bottom of the sliding block 5 is slidably connected to the vertical rail 4. Since there are two horizontal rails 3 and two vertical rails 4 respectively, there are four sliding blocks 5 and they are symmetrically distributed. The four sliding blocks 5 can provide uniform and stable support for the bottom of the support plate 1. The first support rods 11 are hinged at two locations on one side of the bottom of the support plate 2 through a support, and the second support rods 12 are hinged at two locations on one side of the top of the bottom plate 10 through a support. The first support rods 11 and the second support rods 12 are staggered with each other, and a connecting bolt 13 is arranged between the first support rod 11 and the second support rod 12. The two ends of the connecting bolt 13 respectively penetrate the outside of the first support rod 11 and the second support rod 12, and the connecting bolt 13 and their penetration points are fixed to each other through bearings. The other ends of the first support rod 11 and the second support rod 12 are both installed with rollers 14 Due to the staggered arrangement of the second support rod 12 and the first support rod 11, the surface of the roller 14 located at one end of the first support rod 11 contacts the top of the bottom plate 10, while the roller 14 located at one end of the second support rod 12 contacts the surface of the support plate 2. A support mechanism 9 is provided on the top of the bottom plate 10. The support mechanism 9 is used in conjunction with the first support rod 11 to allow the first support rod 11 and the second support rod 12 to rotate synchronously with the connection point of the connecting bolt 13 as the center of the circle, so that the first support rod 11, the second support rod 12 and the roller 14 can provide a lifting support force for the bottom of the support plate 2, thereby allowing the support plate 2 to drive other components arranged above it to be raised and lowered in height. Universal wheels 16 are installed at the four corners of the bottom of the bottom plate 10, and the universal wheels 16 have built-in brakes The structure can be moved on the ground and can also stop its own wheels to prevent movement when necessary. When in use, the device is moved to the bottom of the air-conditioning outdoor unit 17 by the universal wheel 16, and then the position of the universal wheel 16 is locked to limit the position of the device. Then, the height of the support plate 1 is raised by the supporting mechanism 9 to fit the bottom of the air-conditioning outdoor unit 17, and then it continues to rise until it supports the bottom of the air-conditioning outdoor unit 17, so that the support frame 18 remains suspended. A vertical groove 6 is provided on one side of the top of the support plate 1, and a horizontal groove 7 is provided on the other side of the top of the support plate 1. Both the vertical groove 6 and the horizontal groove 7 pass through the bottom of the support plate 1. Adjustment mechanisms 8 are provided on both sides of the top of the support plate 2. The adjustment mechanism 8 on one side is used in conjunction with the vertical groove 6.The support plate 1 can drive the horizontal rail 3 to move horizontally on the sliding block 5, and the adjustment mechanism 8 on the other side cooperates with the horizontal groove 7 to enable the support plate 1 to drive the sliding block 5 to move forward and backward along the surface of the vertical rail 4 through the horizontal rail 3. Based on this, the position of the support plate 1 can be adjusted forward and backward or left and right, so that the staff can conveniently position and debug the position of the air conditioner outdoor unit 17 when installing the air conditioner.

[0028] The supporting mechanism 9 includes a screw rod 91, which is located on one side of the top of the base plate 10. Two support plates 92 are bolted to the top of the base plate 10. One end of the screw rod 91 is rotatably connected to the surface of the support plate 92 on one side through a bearing seat. The other end of the bidirectional screw rod 91 passes through the outer side of the support plate 92 on the other side and is fixed to each other through a bearing at the penetration point. The support plate 92 can provide a stable support effect for the screw rod 91. The other end of the screw rod 91 is fixedly connected to a rotating handle, and the screw rod 91 can be rotated by rotating the handle. The surface of the screw rod 91 is threadedly connected to a slider seat 93, and the bottom of the slider seat 93 is slidably connected to the top of the base plate 10. , both sides of the slider seat 93 are bolted with connecting rods 94, and the other ends of the connecting rods 94 on both sides are bolted to the surfaces of the first struts 11 on both sides respectively. When the screw rod 91 is driven to rotate by the handle, due to the sliding connection between the slider seat 93 and the bottom plate 10, the slider seat 93 can move along the surface of the screw rod 91, and the threaded connection between the screw rod 91 and the slider seat 93 has self-locking properties, so that the connecting rod 94 can push the bottom of the first struts 11 on both sides, so that the two first struts 11 rotate around the connecting bolt 13 as the center. At this time, the rollers 14 at the bottom ends of the two first struts 11 will roll and slide with the top of the bottom plate 10, so that the two first struts The hinge at the top of 11 props up one side of the support plate 2. During this process, the second support rod 12 hinged to both sides of the top of the bottom plate 10 will also rotate synchronously with the connecting bolt 13 as the center, so that the roller 14 at the top of the second support rod 12 can synchronously slide and support the bottom of the support plate 2, thereby providing a relatively balanced lifting support force for the bottom of the support plate 2, and the support plate 2 can drive the support plate 1 to move up and down in height through the connection of the vertical rail 4, the sliding block 5 and the horizontal rail 3. When the support plate 1 is raised and contacts the bottom of the air conditioner outdoor unit 17, it can provide a supporting effect to its bottom, so that the support frame 18 is off the ground and remains suspended. , so that the staff can adjust the position of the air-conditioning outdoor unit 17 through the adjustment mechanism 8, and when the height of the support plate 1 drops and releases the contact with the bottom of the air-conditioning outdoor unit 17, the device can be taken out from under the air-conditioning outdoor unit 17 through the universal wheel 16, so that the staff can continue to use it next time. Slide grooves 15 are provided at two locations at the bottom of the support plate 2 and two locations at the top of the bottom plate 10. The slide grooves 15 correspond to the positions of the rollers 14. The rollers 14 are slidably connected to the inner walls of the slide grooves 15. When the rollers 14 slide and move, the stability of the rollers 14 sliding against the surface of the support plate 2 or the bottom plate 10 can be improved under the restriction of the slide grooves 15.

[0029] The adjusting mechanism 8 includes a rotating column 81, the bottom of which is rotatably connected to the top of the supporting plate 2 through a bearing seat, a bevel gear disc 82 is bolted to the top of the rotating column 81, and a side bevel gear 84 is meshed and connected to one side of the rack below the bevel gear disc 82, and the size of the side bevel gear 84 is smaller than that of the bevel gear disc 82, and a cylindrical shell 85 is bolted to one side of the side bevel gear 84, and a connecting plate 86 is bolted to the bottom of the supporting plate 1, and one end of the cylindrical shell 85 penetrates through two connecting plates 86 and is fixed to each other through a bearing at the penetration point, and the connecting plate 86 can provide a reliable support effect for the cylindrical shell 85, and when the cylindrical shell 85 rotates, it can drive the side bevel gear 84 to the bevel gear disc 82 The side cone gear 84 is smaller than the bevel gear disc 82, so it is easier to drive the bevel gear disc 82 in meshing mode. The inner cavity of the cylindrical shell 85 is provided with an auxiliary component 87, which can not only facilitate the staff to rotate the cylindrical shell 85, but also limit the rotation of the cylindrical shell 85. A clamping column 83 is bolted to the edge of the top of the bevel gear disc 82. Since the two adjustment mechanisms 8 are distributed on both sides of the top of the support plate 2, the clamping column 83 on one side is slidably connected to the inner wall of the vertical groove 6, and the clamping column 83 on the other side is slidably connected to the inner wall of the horizontal groove 7. When the outdoor unit 17 is to be adjusted in the horizontal position, the auxiliary component 87 located on one side of the vertical slot 6 is first operated to drive the cylindrical shell 85 and the side bevel gear 84 to rotate, so that the side bevel gear 84 engages with the bevel gear plate 82 to drive the clamping column 83 to rotate, so that the rotating clamping column 83 can push the inner wall of the vertical slot 6 to the left and right, and due to the sliding connection between the horizontal rail 3 and the top of the sliding block 5, the clamping column 83 can push the support plate 1 and the horizontal rail 3 to move horizontally along the top of the sliding block 5 through the vertical slot 6. When the longitudinal position of the outdoor unit 17 of the air conditioner needs to be adjusted, the auxiliary component 87 located on one side of the horizontal slot 7 is first operated to drive the cylindrical shell 85 and The side bevel teeth 84 rotate, allowing the side bevel teeth 84 to engage the bevel gear disk 82 to drive the clamping column 83 to rotate, so that the clamping column 83 can push the inner wall of the horizontal groove 7. Due to the sliding connection between the vertical rail 4 and the bottom of the sliding block 5, the clamping column 83 can push the support plate 1, the horizontal rail 3 and the sliding block 5 to move forward and backward along the top of the vertical rail 4 through the horizontal groove 7. Based on this, the two sets of adjustment mechanisms 8 can conveniently and quickly make the support plate 1 adjust the horizontal or vertical position of the air-conditioning outdoor unit 17. Compared with the traditional method of multiple people cooperating to move the air-conditioning outdoor unit 17 for position adjustment, it can save labor and improve the efficiency of installation.

[0030] The auxiliary component 87 includes a square rod 871, which is slidably connected to the inner cavity of the cylindrical shell 85. A limiting plate 873 is bolted to one side of the support plate 1. A through hole corresponding to the position and size of the square rod 871 is provided in the center of the limiting plate 873. One end of the square rod 871 extends to its outside through the through hole of the limiting plate 873. The inner wall of the through hole of the limiting plate 873 does not contact the surface of the square rod 871. A handle 872 is bolted to one end of the square rod 871. The staff can rotate the square rod 871 to drive the cylindrical shell 85 to rotate by rotating the handle 872. The square rod 871 is partially pulled out of the inner wall of the cylindrical shell 85 by the handle 872, which can extend the rotation operation distance and make it more convenient for the staff to rotate the handle 872. A plurality of positioning holes 874 are provided on the surface of the limiting plate 873, and a positioning column 874 is bolted to one side of the handle 872. 75, there are two positioning posts 875 and they are symmetrically distributed, the positions and sizes of the positioning posts 875 and the positioning holes 874 correspond, when it is necessary to limit the rotation of the cylindrical shell 85, the handle 872 can be pushed to insert the positioning posts 875 into the corresponding positioning holes 874, and the handle 872 can be limited, so that the cylindrical shell 85 will not rotate accidentally, thereby improving the stability of the position adjustment of the air-conditioning outdoor unit 17, the limiting plate 873 is made of neodymium iron boron magnet, and the positioning post 875 is made of nickel-iron alloy, when the positioning post 875 contacts the positioning hole 874 of the limiting plate 873, magnetic attraction will be generated between them, so that the positioning post 875 will not accidentally detach from the positioning hole 874, thereby further improving the limiting effect between the positioning post 875 and the positioning hole 874.

[0031] It is worth noting that the universal wheel 16 proposed in this technical solution is a prior art, and the universal wheel 16 has a brake structure that can stop itself, and the working principle and beneficial effects when used are not described in detail here.

[0032] Working principle: First, the air conditioner outdoor unit 17 is lifted and bolted to the support frame 18 by the lifting equipment, and then the device is pushed under the air conditioner outdoor unit 17 by the universal wheel 16, and then the position of the universal wheel 16 is locked. Next, the handle of the screw rod 91 is rotated to make the slider seat 93 drive the connecting rod 94 to move, so that the two connecting rods 94 can push the two first support rods 11 to rotate around the connecting bolt 13 as the center, and at this time, the second support rod 12 will synchronously rotate around the connecting bolt 13 as the center, so that the first The support rod 11, the second support rod 12 and the roller 14 provide lifting support for the bottom of the support plate 2, and through the connection between the support plate 2, the vertical rail 4, the sliding block 5 and the horizontal rail 3, the support plate 1 can be driven to rise and contact the bottom of the air conditioner outdoor unit 17 for lifting, so that the support frame 18 can be left off the ground and kept suspended, which can facilitate the position adjustment of the air conditioner outdoor unit 17. When it is necessary to fine-tune the position of the air conditioner outdoor unit 17 horizontally, first rotate the handle 872 located on one side of the vertical slot 6 to make the square rod 871 drive the cylindrical The shell 85 and the side bevel gear 84 rotate to engage and rotate the bevel gear disc 82, so that the clamping column 83 can push the support plate 1 and the cross rail 3 to move left and right along the top of the sliding block 5 through the vertical slot 6, thereby the position of the air-conditioning outdoor unit 17 can be moved left and right. After adjustment, the handle 872 is pushed to insert the positioning column 875 into the corresponding positioning hole 874, which can achieve the effect of limiting the cylindrical shell 85, so that the stability of the position after adjustment is guaranteed. When it is necessary to fine-tune the position of the air-conditioning outdoor unit 17 longitudinally, the adjusting mechanism 8 located on one side of the cross slot 7 is first operated to make the clamping column 83 push the support plate 1 through the cross slot 7, so that it moves back and forth along the vertical rail 4 through the cross rail 3 and the sliding block 5. Accordingly, the position of the air-conditioning outdoor unit 17 can be conveniently fine-tuned horizontally or longitudinally through the setting of the two sets of adjusting mechanisms 8. When the position of the air-conditioning outdoor unit 17 is adjusted, the height of the support plate 1 can be lowered by the supporting mechanism 9, and the device can be taken out from under the air-conditioning outdoor unit 17 for continued use next time.
