Specific embodiments

[0027] To make the above objects, features, and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings of the specification.

[0028] Example 1, refer to Figures 1 to 5, which is the first embodiment of the present invention. This embodiment provides a multi-functional fixing device for the outdoor unit of a heating, ventilation, and air conditioning (HVAC) system, which can achieve the effect of directly disassembling the outdoor unit of the air conditioner indoors. It includes a support component 100, which includes two vertical first brackets 101, two second brackets 102 arranged on the two first brackets 101, an outdoor unit body 103 arranged on the second brackets 102, an installation cavity 104 arranged on the second brackets 102, a round opening 105 arranged on the installation cavity 104, a strip-shaped opening 106 arranged on the round opening 105, a cylinder 107 arranged on the outdoor unit body 103, and two pairs of rollers 108 arranged on the cylinder 107; a limiting component 200, which includes a guiding 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 guiding component 201, and a transmission component 204 arranged on the pushing component 203; a fall prevention component 300, which includes a one-way component 301 arranged on the guiding component 201, an unlocking component 302 arranged on the guiding 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. There is a gap between the outdoor unit body 103 and the first bracket 101. The diameter of the round opening 105 is larger than the diameter of the roller 108, and the width of the strip-shaped opening 106 is smaller than the diameter of the roller 108. Thus, when the roller 108 is aligned with the round opening 105, the outdoor unit body 103 can be removed.

[0030] Furthermore, the guiding component 201 includes a T-shaped groove 201a arranged on the first bracket 101. A T-shaped block 201b is slidably connected in the T-shaped groove 201a, and the T-shaped block 201b is fixedly connected to the second bracket 102. The blocking component 202 includes baffles 202a arranged on the two second brackets 102. Multiple first threaded holes 202b are provided on the baffles 202a. Second threaded holes are provided on both second brackets 102. First bolts 202c passing through the first threaded holes 202b and the second threaded holes are provided on the baffles 202a. The rear side wall of the baffle 202a abuts against the front side wall of the outdoor unit body 103. A horizontal opening 202d is provided on the inner wall of the installation cavity 104. A plug 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 plug block 202e.

[0031] Among them, the T-shaped groove 201a cooperates with the T-shaped block 201b to prevent the T-shaped block 201b from detaching from the T-shaped groove 201a. The setting of the baffle 202a can prevent the air conditioner outdoor unit body 103 from sliding outwards. At the same time, the setting of multiple first threaded holes 202b enables the distance between the two first brackets 101 to be adjusted, so as to be applicable to air conditioner outdoor unit bodies 103 of different sizes. The setting of the arc edge 202f prevents the phenomenon of jamming between the roller 108 and the insertion block 202e.

[0032] Preferably, the pushing component 203 includes a support groove 203a arranged in the second bracket 102. A sliding plate 203b is slidably connected in the support groove 203a. The sliding plate 203b is elastically connected to the inner wall of the support groove 203a through a first spring 203c. A guiding port 203d communicating with the installation cavity 104 is arranged in the support groove 203a. A guiding block 203e is slidably connected in the guiding port 203d. A pushing block 203f is fixedly connected to the guiding block 203e. An extension groove 203g is arranged on the insertion block 202e. Transmission shafts 203h are fixedly connected to both the extension groove 203g and the pushing block 203f. A transmission plate 203i is rotatably connected to the rear-end transmission shaft 203h. The transmission plate 203i is rotatably connected to the front-end transmission shaft 203h; the transmission component 204 includes a first installation groove 204a arranged in the T-shaped block 201b. The first installation groove 204a communicates with the support groove 203a. A first top block 204b is fixedly connected to the sliding plate 203b. A second top block 204c is slidably connected in the first installation groove 204a. Inclined surfaces are arranged on both the first top block 204b and the second top block 204c. An abutting block 204d is fixedly connected to the second top block 204c. A communication port for the abutting block 204d to pass through is arranged on the T-shaped block 201b. The second top block 204c is elastically connected to the inner wall of the first installation groove 204a through a second spring 204e.

[0033] It should be noted that the width of the guiding port 203d is smaller than the width of the extension groove 203g. The width of the extension groove 203g is sufficient, so that the phenomenon of jamming with the extension groove 203g will not occur during the movement of the transmission plate 203i. The setting of the inclined surface prevents the phenomenon of jamming between the first top block 204b and the second top block 204c.

[0034] When in use, first, when the outdoor unit of the air conditioner is at the lower end of the window, fix the first bracket first, then tie the outdoor unit of the air conditioner with a rope and hoist it to the upper side of the second bracket 102. Then align the roller 108 on the air conditioner with 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 to quickly align the roller 108 on the outdoor unit body 103 with the circular opening 105). Then slowly lower the outdoor unit body 103, and the roller 108 can enter the circular opening 105. Then push the outdoor unit body 103 so that the roller 108 slides in the installation cavity 104. The setting of the roller 108 here makes it easier to push the outdoor unit body 103. When the outer side wall of the outdoor unit body 103 abuts against the inner side wall of the baffle 202a, stop pushing the outdoor unit body 103. During the pushing process, since the width of the strip-shaped 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, thus preventing the outdoor unit body 103 from tipping over. During the process that the outer side wall of the outdoor unit body 103 moves to abut against the inner side wall of the baffle 202a, the roller 108 will first fit with the arc edge 202f of the insertion block 202e. At this time, the roller 108 will push the insertion block 202e to move outward, making the transmission plate 203i move forward, the push block 203f move forward, thus the guiding block 203e move forward, the sliding plate 203b move forward, and the first spring 203c is compressed. When the roller 108 passes over the insertion block 202e, under the action of the first spring 203c, the insertion block 202e is reset through transmission. At this time, the non-arc edge 202f of the insertion block 202e abuts against the roller 108, preventing the roller 108 from resetting. At this time, the front-back, up-down, and left-right directions of the roller 108 are all limited, thus realizing the fixation of the position of the roller 108, the fixation of the cylinder 107, and the fixation of the outdoor unit body 103. When the outdoor unit body 103 needs to be disassembled, just put the rope on the outdoor unit body 103 and then pull the outdoor unit body 103 upward. During this process, the roller 108 abuts against the inner top of the installation cavity 104, driving the second bracket 102 to move upward, so that the T-shaped block 201b moves upward for guiding. When the outdoor unit body 103 moves to a position not far below the window, the T-shaped block 201b abuts against the inner top of the T-shaped groove 201a, making the abutting block 204d move towards the support groove 203a, and the second top block 204c move downward to push the first top block 204b towards the sliding plate 203b, and the second spring 204e elongates. When the first top block 204b moves, it can drive the sliding plate 203b to slide, drive the guiding block 203e to move, thus the push block 203f moves towards the insertion block 202e, and through the transmission plate 203i, the insertion block 202e moves towards the outer end, so that the insertion block 202e does not abut against the roller 108. At this time, the outdoor unit body 103 can be pulled so that the roller 108 is aligned with the circular opening 105.Then, pulling the air conditioner outdoor unit body 103 upward can disassemble the air conditioner outdoor unit body 103, so that when performing subsequent maintenance on the air conditioner, workers do not need to climb with safety ropes to disassemble the air conditioner outdoor unit.

[0035] In summary, by setting the limiting component 200, the round opening 105, the strip-shaped opening 106, the roller 108 and the cylinder 107, after the first bracket 101 and the second bracket 102 are installed, when installing or disassembling the air conditioner outdoor unit body, workers do not need to climb with safety ropes to disassemble or install the air conditioner outdoor unit, thus protecting the safety of workers and reducing the occurrence of safety accidents.

[0036] Embodiment 2, referring to Figures 1 to 7 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an anti-falling component 300 for the multifunctional HVAC outdoor unit fixing device, which solves the problem of how to prevent the air conditioner outdoor unit body 103 from falling midway when pulling the air conditioner outdoor unit body 103 upward. It includes a one-way component 301, including an extension slot 301a provided on the inner wall of the T-shaped slot 201a. A plurality of first ratchet teeth 301b are fixedly connected in the extension slot 301a. A second installation slot 301c is provided on the T-shaped block 201b. A rotating shaft 301d is fixedly connected in the second installation slot 301c. A second ratchet tooth 301e that cooperates with the first ratchet tooth 301b is rotatably connected to the rotating shaft 301d. A torsion spring 301f is provided on the rotating shaft 301d. The unlocking component 302 includes a communication slot 302a provided on the first installation slot 204a. A double-headed threaded rod 302b is rotatably connected in the communication slot 302a. The middle part of the double-headed threaded rod 302b is not provided with threads, and the thread directions at both ends of the double-headed threaded rod 302b are opposite. A gear 302c is fixedly connected to the middle part of the double-headed threaded rod 302b. A U-shaped tooth plate 302d is slidably connected in the first installation slot 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-headed threaded rod 302b. The stop block 302f is slidably connected to the communication slot 302a; the upper side wall of the second ratchet tooth 301e abuts against the lower side wall of the stop block 302f. Both the upper and lower side walls of the second ratchet tooth 301e are arc-shaped. The height of the stop block 302f is greater than the arc length of the upper side wall of the second ratchet tooth 301e; the reset component 303 includes a through hole 303a that penetrates the support slot 203a. A top rod 303b that cooperates with the through hole 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 is misaligned with the second pawl 301e, there is enough space for the second pawl 301e to deflect upward to accommodate the second pawl 301e. The threaded setting of the double-headed threaded rod 302b has a self-locking function, which can prevent the phenomenon of the stop block 302f sliding when it abuts against the second pawl 301e. The thread directions at both ends of the double-headed threaded rod 302b are opposite, so that the two stop blocks 302f can move inward or outward simultaneously. There is no thread in the middle of the double-headed threaded rod 302b, and the unthreaded part extends into the communication groove 302a, so that when the double-headed threaded rod 302b rotates, the phenomenon of self-sliding of the double-headed threaded rod 302b will not occur. At the same time, holes communicating with the first installation groove 204a are provided on the side wall of the communication groove 302a, so that the unthreaded part of the double-headed threaded rod 302b is rotationally connected to the inner wall of the hole.

[0038] During 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 obtains elasticity. When the second pawl 301e passes over the first pawl 301b, under the action of the torsion spring 301f, the second pawl 301e resets and cooperates with the first pawl 301b. When the air conditioner outdoor unit body 103 is pulled and the rope slips out of the hand, since the first pawl 301b is abutted by the stop block 302f and cannot deflect upward, at this time the first pawl 301b abuts against the second pawl 301e, and the first pawl 301b cannot move downward, so that the T-shaped block 201b cannot move downward, the second bracket 102 cannot move downward, and the air conditioner outdoor unit body 103 will not fall by itself, avoiding a large impulse impact on the first bracket 101 caused by the rapid descent of the air conditioner outdoor unit body 103 and preventing the first bracket 101 from loosening. When the T-shaped block 201b abuts against the inner top of the T-shaped groove 201a, the abutting block 204d drives the second top block 204c to move downward. At this time, the push rod 302e can be driven to move downward, causing the U-shaped tooth plate 302d to move downward and driving the gear 302c to rotate. At this time, the two stop blocks 302f move towards the middle and are misaligned with the first pawl 301b, so that the first pawl 301b can deflect upward and will not be blocked during the downward movement of the T-shaped block 201b, without affecting the downward movement of the T-shaped block 201b. It should be noted that after the stop block 302f is misaligned with the first pawl 301b, since the roller 108 is still in the installation cavity 104 at this time and the air conditioner outdoor unit body 103 is still in the pulled state, the second bracket 102 will not move directly downward, and it is always ensured that the second bracket 102 will automatically reset only after the air conditioner outdoor unit body 103 is removed. When the T-shaped block 201b resets, it can push the ejector rod 303b to move upward. At this time, the U-shaped tooth plate 302d moves upward, driving the gear 302c to rotate, causing the double-headed threaded rod 302b to rotate, and the stop block 302f to return to the upper side of the second pawl 301e for the next use.

[0039] In summary, by setting the anti-falling component 300, during the process of pulling the air conditioner body, even if the rope slips out of the hand, the air conditioner outdoor unit body 103 will not rapidly descend, avoiding the rapid descent of the air conditioner outdoor unit body 103 and the large impact force that may cause the first bracket 101 to be loosened due to a large impulse.

[0040] Example 3, refer to 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 the multi-functional HVAC outdoor unit fixing device, which solves the problem of how to pull the outdoor unit body 103 on one side of the window to the lower end of the window. It includes an extension component 304, which includes a third bracket 304a fixedly connected to the first bracket 101. The third bracket 304a is provided with an anti-detachment groove 304b communicating with the T-shaped groove 201a. The anti-detachment groove 304b cooperates with the T-shaped block 201b. The inner wall of the anti-detachment groove 304b is provided with an outward expansion groove 304c for cooperating with the ejector rod 303b. Fixed blocks 304d are provided on both the third bracket 304a and the first bracket 101, and a second bolt is threadedly connected to the fixed block 304d.

[0041] Specifically, the third bracket 304a and the first bracket 101 are perpendicular to each other, and the anti-detachment groove 304b on the third bracket 304a communicates with the T-shaped groove 201a. When the upper end surface of the T-shaped block 201b abuts against the inner top of the T-shaped groove 201a, the T-shaped block 201b just enters the anti-detachment groove 304b. The setting of the outward expansion groove 304c here can accommodate the ejector rod 303b and avoid the phenomenon that the ejector rod 303b gets stuck with the anti-detachment groove 304b.

[0042] During use, sometimes the outdoor unit body 103 is not set directly below the window, but on one side of the window. At this time, when the outdoor unit body 103 is pulled to a height close to the window, just pull the outdoor unit body 103 to the left or right to make the outdoor unit body 103 move directly below the window. A hook can be set on the outdoor unit body 103 to facilitate pulling the outdoor unit body 103. During this process, the T-shaped block 201b slides in the anti-detachment groove 304b for guiding. The inner top of the T-shaped groove 201a and the inner top of the anti-detachment groove 304b are at the same height. Therefore, when the T-shaped block 201b slides in the anti-detachment groove 304b, it will not cause the abutting block 204d to automatically reset.

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

Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
