DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figure 1 to Figure 5 In an embodiment of the utility model, a central air conditioner installation auxiliary device includes a workbench 1, and support legs 2 are fixedly connected at the four corners of the bottom end of the workbench 1. Two support legs 2 coaxially arranged along the width direction of the workbench 1 are connected by a cross bar 3, and a through hole is opened at the center of the workbench 1;

[0032] Two winding units are symmetrically arranged on both sides of the top of the workbench 1 through a support seat 9, and the winding units are connected to a connecting handle 7 through a winding belt 16;

[0033] A synchronization unit is installed at one end of the two support seats 9, and the synchronization unit is connected to the workbench 1 through the support seats 9;

[0034] A crank 10 is installed at one end of a winding unit, and a one-way unit is distributed on the crank 10 and a support seat 9 supporting the winding disc 8;

[0035] The one-way unit is used to limit the rotation direction of the winding unit.

[0036] In this embodiment: when driving the indoor unit of the suspended central air conditioner to move upward, by rotating the crank 10, the crank 10 drives a winding unit to rotate, and the winding unit drives another winding unit to rotate synchronously in the opposite direction through the synchronization unit, and the two winding units drive the indoor unit of the suspended central air conditioner to move upward;

[0037] At the same time, when the ratchet 18 of the one-way mechanism of the winding unit rotates, the one-way mechanism does not limit the rotation of the winding unit during the winding process. When the rotation of the winding unit is stopped, the one-way mechanism limits the reverse rotation of the winding unit to avoid the unwinding action of the winding unit.

[0038] Please refer to Figure 1 and Figure 2 The winding unit includes two winding reels 8 mounted on the workbench 1 through a support seat 9, and a concentric shaft 17 is fixedly connected to the center of the winding reels 8, and the concentric shaft 17 is rotatably connected to the support seat 9;

[0039] The winding unit further includes two vertical rails 4 symmetrically fixedly connected to the inner side of the through hole, the top of the vertical rail 4 is rotatably connected to a fixed pulley 5 through a bracket, and the bottom of the connecting handle 7 is connected to a lifting platform 6;

[0040] The outer wall of the winding drum 8 is connected with a winding belt 16 which contacts the outer wall of the fixed pulley 5 and extends downward to be connected to the connecting handle 7 .

[0041] In this embodiment: by turning the crank 10, the crank 10 drives a winding reel 8 to rotate, and the winding reel 8 drives another winding reel 8 to rotate simultaneously and in the opposite direction through a synchronization unit. The winding reel 8 reels the winding belt 16, and the two winding belts 16 drive the lifting platform 6 to rise through the connecting handle 7, and the lifting platform 6 drives the indoor unit of the suspended central air conditioner placed on the top of it to move upward until the height of the suspended central air conditioner is adjusted to a preset height.

[0042] Please refer to Figure 1 and Figure 2 The synchronization unit includes a first synchronization wheel 11, a second synchronization wheel 13 and a gear 15 arranged along the length direction of the workbench 1, and the outer walls of the first synchronization wheel 11, the second synchronization wheel 13 and the gear 15 are rotatably connected to a support seat 9 connected to the top of the workbench 1;

[0043] The first synchronous wheel 11 is connected to the second synchronous wheel 13 through a synchronous belt 12. A tooth block 14 is formed on the outer wall edge of the second synchronous wheel 13. The tooth block 14 is meshed with a gear 15. The first synchronous wheel 11 and the gear 15 are respectively connected to one end of two concentric shafts 17.

[0044] In this embodiment, when one winding drum 8 is rotating, the winding drum 8 drives the coaxial shaft 17 connected thereto to rotate, and the coaxial shaft 17 drives the No. 1 synchronous wheel 11 to rotate, and the No. 1 synchronous wheel 11 drives the synchronous belt 12 to drive the No. 2 synchronous wheel 13 to rotate, and the No. 2 synchronous wheel 13 drives the gear 15 to rotate through the tooth blocks 14 formed equidistantly and circumferentially on its outer wall, and the gear 15 drives the other winding drum 8 to rotate through the coaxial shaft 17 connected thereto, so that the two winding drums 8 rotate synchronously and in opposite directions.

[0045] Please refer to Figure 1 , the crank 10 is connected to one end of a concentric shaft 17;

[0046] The one-way unit includes a ratchet 18 mounted on the outer wall of the crank 10 and a ratchet 19 rotatably connected to the end of the support seat 9;

[0047] A center hole 20 is formed at the inner center of the support seat 9, and a rotating shaft 23 is integrally formed with the ratchet 19. The rotating shaft 23 is rotatably connected to one end of the inner wall of the center hole 20, and a torsion spring 21 is engaged between one end of the inner wall of the center hole 20 and one end of the ratchet 19;

[0048] An arc groove 22 is formed at one end of the support seat 9 below the central hole 20 , and a movable column 24 is integrally formed at one end of the ratchet 19 .

[0049] In this embodiment, when the crank 10 rotates, the crank 10 drives the ratchet 18 to rotate. When the ratchet 18 rotates, the side of the ratchet 19 close to the ratchet 18 is squeezed. The ratchet 19 rotates around the rotating shaft 23. The ratchet 19 drives the torsion spring 21 to twist. At the same time, the ratchet 19 drives the movable column 24 to rotate along the arc groove 22, so as not to interfere with the rotation of the ratchet 18.

[0050] When the crank 10 stops turning, the gravity of the indoor unit of the suspended central air conditioner acts on the winding drum 8 through the winding belt 16. At this time, the winding drum 8 has a reverse drive, and the ratchet 19 cannot reverse, forming a limiting force on the ratchet 18, thereby ensuring that the winding drum 8 remains stable.

[0051] Please refer to Figure 4 The movable column 24 is movably connected to the inner cavity of the arc groove 22, and the center of the arc groove 22 coincides with the center of the rotating shaft 23.

[0052] In this embodiment: the ratchet 19 can only rotate in one direction (eg: Figure 5 shown).

[0053] Please refer to the figure in particular. Both ends of the lifting platform 6 are integrally formed with sliders, and the sliders are connected to the inner cavity of the vertical rail 4 for sliding up and down.

[0054] In this embodiment, the lifting platform 6 is driven by force to move the slider up and down in the vertical rail 4, and the moving direction of the lifting platform 6 is limited.

[0055] Please refer to the figure in particular, one end of the lifting platform 6 is formed with a downwardly inclined slope.

[0056] In this embodiment, it is convenient to carry the indoor unit of the suspended central air conditioner to the top of the lifting platform 6 via the inclined surface.

[0057] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
