[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0028] Example 1, reference Figure 1 to Figure 5, which is the first embodiment of the present invention, provides a multifunctional HVAC outdoor unit fixing device, which can achieve the effect of directly disassembling the air conditioner outdoor unit indoors, and includes a supporting component 100, including two vertical first brackets 101, two second brackets 102 arranged on the two first brackets 101, an air conditioner outdoor unit body 103 arranged on the second brackets 102, an installation cavity 104 arranged on the second bracket 102, a circular opening 105 arranged on the installation cavity 104, a strip opening 106 arranged on the circular opening 105, a column 107 arranged on the air conditioner outdoor unit body 103, and Two pairs of rollers 108 are arranged on the cylinder 107; the limiting component 200 includes a guide component 201 arranged on the first bracket 101, a blocking component 202 arranged on the second bracket 102, a pushing component 203 arranged on the guide component 201, and a transmission component 204 arranged on the pushing component 203; the anti-fall component 300 includes a one-way component 301 arranged on the guide component 201, an unlocking component 302 arranged on the guide component 201, a reset component 303 arranged on the unlocking component 302, and an extension component 304 arranged on the first bracket 101.

[0029] Specifically, the first bracket 101 and the second bracket 102 are perpendicular to each other, a gap is provided between the air conditioner outdoor unit body 103 and the first bracket 101, the diameter of the circular opening 105 is larger than the diameter of the roller 108, and the width of the strip opening 106 is smaller than the diameter of the roller 108, so that the air conditioner outdoor unit body 103 can be taken out only when the roller 108 is facing the circular opening 105.

[0030] Furthermore, the guide assembly 201 includes a T-slot 201a arranged on the first bracket 101, a T-block 201b is slidably connected in the T-slot 201a, and the T-block 201b is fixedly connected to the second bracket 102; the blocking assembly 202 includes a baffle 202a arranged on the two second brackets 102, a plurality of first threaded holes 202b are provided on the baffle 202a, and second threaded holes are provided on the two second brackets 102, and a first bolt 202c is provided on the baffle 202a that passes through the first threaded hole 202b and the second threaded hole, the rear side wall of the baffle 202a is abutted against the front side wall of the air conditioner outdoor unit body 103, a horizontal opening 202d is provided on the inner wall of the installation cavity 104, an insert block 202e that cooperates with the roller 108 is slidably connected in the horizontal opening 202d, and an arc edge 202f is provided on the insert block 202e.

[0031] Among them, the T-slot 201a cooperates with the T-block 201b to prevent the T-block 201b from being separated from the T-slot 201a. The setting of the baffle 202a can prevent the air-conditioning outdoor unit body 103 from sliding outward. At the same time, the setting of multiple first threaded holes 202b makes the distance between the two first brackets 101 adjustable, so as to adapt to air-conditioning outdoor unit bodies 103 of different sizes. The setting of the arc edge 202f can avoid the phenomenon of jamming between the roller 108 and the plug block 202e.

[0032] Preferably, the pushing assembly 203 includes a supporting groove 203a arranged in the second bracket 102, a slide plate 203b is slidably connected in the supporting groove 203a, the slide plate 203b is elastically connected to the inner wall of the supporting groove 203a through a first spring 203c, a guide opening 203d communicating with the mounting cavity 104 is provided in the supporting groove 203a, a guide block 203e is slidably connected in the guide opening 203d, a push block 203f is fixedly connected to the guide block 203e, an extension groove 203g is provided on the insert block 202e, a transmission shaft 203h is fixedly connected to the extension groove 203g and the push block 203f, and a transmission plate 203i is rotatably connected to the rear end transmission shaft 203h. The transmission plate 203i is rotationally connected to the front end transmission shaft 203h; the transmission assembly 204 includes a first mounting groove 204a arranged in the T-shaped block 201b, the first mounting groove 204a is connected to the supporting groove 203a, a first top block 204b is fixedly connected to the slide plate 203b, a second top block 204c is slidably connected in the first mounting groove 204a, the first top block 204b and the second top block 204c are both provided with inclined surfaces, a resist block 204d is fixedly connected to the second top block 204c, a connecting port is provided on the T-shaped block 201b for the resist block 204d to pass through, and the second top block 204c is elastically connected to the inner wall of the first mounting groove 204a through a second spring 204e.

[0033] It should be noted that the width of the guide opening 203d is smaller than the width of the extension groove 203g. The width of the extension groove 203g is sufficient. During the movement of the transmission plate 203i, there will be no jamming with the extension groove 203g. The setting of the inclined surface avoids jamming between the first top block 204b and the second top block 204c.

[0034] When in use, first, with the air-conditioning outdoor unit at the lower end of the window, fix the first bracket first, then tie the air-conditioning outdoor unit with a rope and hang it on the upper side of the second bracket 102, and then make the roller 108 on the air conditioner face the circular opening 105 on the second bracket 102 (here two reference lines can be drawn on the air conditioner and the first bracket 101 so that the roller 108 on the air-conditioning outdoor unit body 103 can quickly face the circular opening 105), and then slowly lower the air-conditioning outdoor unit body 103 to allow the roller 108 to enter the circular opening 105, and then push the air-conditioning outdoor unit body 103 to make the roller 108 slide in the installation cavity 104. The setting of the roller 108 here makes the air-conditioning outdoor unit body 103 easier to be pushed. When the wall of the air conditioner outdoor unit 103 abuts against the inner wall of the baffle 202a, the pushing of the air conditioner outdoor unit body 103 stops. During the pushing process, since the width of the strip opening 106 is smaller than the diameter of the roller 108, the upper end surface of the roller 108 abuts against the inner top of the installation cavity 104, thereby preventing the air conditioner outdoor unit body 103 from tipping over. In the process where the air conditioner outdoor unit body 103 moves to the point where the outer wall of the air conditioner outdoor unit body 103 abuts against the inner wall of the baffle 202a, the roller 108 will first fit with the arc edge 202f of the plug block 202e. At this time, the roller 108 will push the plug block 202e to move outward, causing the transmission plate 203i to move forward, the push block 203f to move forward, thereby the guide block 203e moves forward, the slide plate 203b moves forward, and the first spring 203c is compressed. When the roller 108 passes over the plug block 202e, the plug block 202e is reset through transmission under the action of the first spring 203c. At this time, the non-arc edge 202f of the plug block 202e abuts against the roller 108 to prevent the roller 108 from resetting. At this time, the front and back, up and down, left and right of the roller 108 are limited, thereby achieving the fixation of the position of the roller 108, the fixation of the cylinder 107, and the fixation of the air-conditioning outdoor unit body 103. When the air-conditioning outdoor unit body 103 needs to be disassembled, it is only necessary to put the rope on the air-conditioning outdoor unit body 103, and then pull the air-conditioning outdoor unit body 103 upward. In this process, the roller 108 abuts against the top of the installation cavity 104, driving the second bracket 102 to move upward, so that the T-shaped block 201b moves upward. When the air conditioner outer unit body 103 moves to a position not far from the lower side of the window, the T-shaped block 201b abuts against the inner top of the T-shaped slot 201a, so that the abutting block 204d moves toward the supporting slot 203a, and the second top block 204c moves downward to push the first top block 204b to move toward the slide plate 203b. The second spring 204e stretches, and when the first top block 204b moves, it can drive the slide plate 203b to slide, and drive the guide block 203e to move, so that the push block 203f moves toward the insertion block 202e, and the insertion block 202e moves toward the outer end through the transmission plate 203i, so that the insertion block 202e does not abut against the roller 108. At this time, the air conditioner outer unit body 103 can be pulled so that the roller 108 is directly opposite to the round mouth 105.Then the air conditioner outer unit body 103 can be disassembled by pulling the air conditioner outer unit body 103 upwards, so that when the air conditioner is subsequently repaired, workers do not need to climb up with a safety rope to disassemble the air conditioner outer unit.

[0035] In summary, by setting the limiting component 200, the circular opening 105, the strip opening 106, the roller 108 and the cylinder 107, it is only necessary to install the first bracket 101 and the second bracket 102. When installing or disassembling the air conditioner main body external unit, workers do not need to climb with a safety rope to disassemble or install the air conditioner external unit, thereby protecting the safety of workers and reducing the occurrence of safety accidents.

[0036] Example 2, reference Figure 1 to Figure 7 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an anti-falling component 300 of a multifunctional HVAC outdoor unit fixing device, which solves the problem of how to prevent the air conditioner outdoor unit body 103 from falling off midway when the air conditioner outdoor unit body 103 is pulled upward. It includes a one-way component 301, including an expansion slot 301a arranged on the inner wall of the T-shaped slot 201a, and a plurality of first pawls 301b are fixedly connected in the expansion slot 301a. The T-shaped block 201b is provided with a second mounting slot 301c, and a rotating shaft 301d is fixedly connected in the second mounting slot 301c. The rotating shaft 301d is rotatably connected with a second pawl 301e that cooperates with the first pawl 301b, and a torsion spring 301f is provided on the rotating shaft 301d. The unlocking component 302 includes a connecting slot 302a arranged on the first mounting slot 204a, and a double-headed thread is rotatably connected in the connecting slot 302a. Rod 302b, the middle part of the double-threaded rod 302b is not provided with threads, the threads at both ends of the double-threaded rod 302b are in opposite directions, the middle part of the double-threaded rod 302b is fixedly connected with a gear 302c, a U-shaped tooth plate 302d is slidably connected in the first mounting groove 204a, a push rod 302e that abuts against the U-shaped tooth plate 302d is fixedly connected to the push block 203f, a stop block 302f is threadedly connected to the double-threaded rod 302b, and the stop block 302c is fixedly connected to the stop block 303f. 02f is slidably connected to the connecting groove 302a; the upper side wall of the second pawl 301e is abutted against the lower side wall of the stop block 302f, the upper and lower side walls of the second pawl 301e are both arc-shaped, and the height of the stop block 302f is greater than the arc length of the upper side wall of the second pawl 301e; the reset component 303 includes a through opening 303a passing through the supporting groove 203a, and a top rod 303b matching the through opening 303a is fixedly connected to the U-shaped tooth plate 302d.

[0037] Specifically, the upper side wall of the second pawl 301e abuts against the lower side wall of the stop block 302f. When the stop block 302f extends to the upper side of the second pawl 301e, the second pawl 301e cannot deflect upward. At the same time, the height of the stop block 302f here is greater than the arc length of the upper side wall of the second pawl 301e. When the stop block 302f and the second pawl 301e are misaligned, there is enough space for the second pawl 301e to deflect upward. The threaded setting of the double-headed threaded rod 302b has a self-locking function, which can prevent the stop block 302f from abutting against the second pawl 301e. , the stop block 302f slides. The threads at both ends of the double-headed threaded rod 302b are in opposite directions, so that the two stop blocks 302f can move inward or outward at the same time. There is no thread in the middle of the double-headed threaded rod 302b, and the unthreaded part extends into the connecting groove 302a, so that when the double-headed threaded rod 302b rotates, the double-headed threaded rod 302b will not slide by itself. At the same time, a hole that communicates with the first mounting groove 204a is provided on the side wall of the connecting groove 302a, so that the unthreaded part of the double-headed threaded rod 302b can be rotatably connected to the inner wall of the hole.

[0038] When in use, when the T-shaped block 201b moves upward, the second pawl 301e abuts against the first pawl 301b, causing the second pawl 301e to deflect downward, and the torsion spring 301f gains elasticity. When the second pawl 301e passes over the first pawl 301b, under the action of the torsion spring 301f, the second pawl 301e returns to its original position and cooperates with the first pawl 301b. When the air conditioner outdoor unit 103 is pulled and the hand slips and the rope is loosened, the first pawl 301b is abutted by the stop block 302f and cannot move upward. When the first pawl 301b and the second pawl 301e are against each other, the first pawl 301b cannot move downward, so the T-shaped block 201b cannot move downward, so that the second bracket 102 cannot move downward, and the air conditioner outdoor unit body 103 will not fall by itself, so as to avoid the rapid drop of the air conditioner outdoor unit body 103 causing a large impulse to impact the first bracket 101, and prevent the first bracket 101 from loosening. When the T-shaped block 201b is against the top of the T-shaped slot 201a, the abutment block 204d drives the second top block 204 c moves downward, which can drive the push rod 302e to move downward, so that the U-shaped tooth plate 302d moves downward, driving the gear 302c to rotate. At this time, the two stop blocks 302f move toward the middle and are misaligned with the first pawl 301b, so that the first pawl 301b can deflect upward, and will not be hindered during the downward movement of the T-shaped block 201b, and will not affect the downward movement of the T-shaped block 201b. It is worth noting that after the stop block 302f is misaligned with the first pawl 301b, since the roller 108 is still In the installation cavity 104, the air conditioner outdoor unit body 103 is still in a pulled state, so that the second bracket 102 will not move downward directly, and the second bracket 102 will automatically reset only after the air conditioner outdoor unit body 103 is removed. When the T-block 201b is reset, it can push the top rod 303b to move upward. At this time, the U-shaped tooth plate 302d moves upward, driving the gear 302c to rotate, so that the double-headed threaded rod 302b rotates, and the stop block 302f returns to the upper side of the second pawl 301e for next use.

[0039] In summary, by setting the anti-fall component 300, during the process of pulling the air conditioner body, even if the hand slips and the rope loosens, it will not cause the air conditioner outdoor unit body 103 to drop rapidly, thereby preventing the air conditioner outdoor unit body 103 from dropping rapidly and preventing the first bracket 101 from being subjected to a large impact and loosening due to a large impulse.

[0040] Example 3, reference Figures 1 to 8, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an extension component 304 of a multifunctional HVAC outdoor unit fixing device, which solves the problem of how to pull the air-conditioning outdoor unit body 103 on one side of the window to the lower end of the window. It includes an extension component 304, including a third bracket 304a fixedly connected to the first bracket 101, the third bracket 304a is provided with an anti-slip groove 304b connected to the T-slot 201a, the anti-slip groove 304b cooperates with the T-block 201b, the inner wall of the anti-slip groove 304b is provided with an outer expansion groove 304c cooperating with the push rod 303b, the third bracket 304a and the first bracket 101 are both provided with a fixing block 304d, and the fixing block 304d is threadedly connected with a second bolt.

[0041] Specifically, the third bracket 304a is perpendicular to the first bracket 101, and the anti-slip groove 304b on the third bracket 304a is connected to the T-shaped groove 201a. When the upper end surface of the T-shaped block 201b is against the top of the T-shaped groove 201a, the T-shaped block 201b just enters the anti-slip groove 304b. The setting of the outward expansion groove 304c here can accommodate the push rod 303b, avoiding the phenomenon that the push rod 303b is stuck with the anti-slip groove 304b.

[0042] When in use, sometimes the air conditioner outdoor unit body 103 is not arranged directly below the window, but is arranged on one side of the window. At this time, when the air conditioner outdoor unit body 103 is pulled to a height close to the window, the air conditioner outdoor unit body 103 can be moved to the bottom of the window by simply pulling the air conditioner outdoor unit body 103 to the left or right. A hook can be provided on the air conditioner outdoor unit body 103 to pull the air conditioner outdoor unit body 103. During this process, the T-shaped block 201b slides in the anti-slip groove 304b for guidance. The inner top of the T-shaped groove 201a is at the same height as the inner top of the anti-slip groove 304b, so that when the T-shaped block 201b slides in the anti-slip groove 304b, the resistance block 204d will not be automatically reset.

[0043] In summary, by providing the extension component 304, the air conditioner outdoor unit body 103 can be installed not only directly below the window, but also on one side of the window, thereby increasing the installation range of the air conditioner outdoor unit body 103 and having a wider range of use.
