DETAILED DESCRIPTION

[0026] 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.

[0027] Example 1, reference Figure 1 to Figure 5, which is the first embodiment of the present invention, provides a HVAC fixing device, which can achieve the effect that one person can install the indoor unit of the air conditioner, and includes a bearing component 100, including a U-shaped frame 101, four extension blocks 102 arranged on the U-shaped frame 101, three threaded holes 103 arranged on the extension blocks 102, a first slide plate 104 arranged on the U-shaped frame 101, and a hanging plate 105 arranged on the first slide plate 104; an extension component 200, including a sliding component arranged on the U-shaped frame 101 201, and a limiting component 202 arranged on the hanging plate 105; the anti-loosening component 300, including a one-way component 301 arranged on the sliding component 201, and an elastic component 302 arranged on the one-way component 301; the unlocking component 400, including a threaded component 401 arranged on the U-shaped frame 101, a pushing component 402 arranged on the threaded component 401, an extrusion component 403 arranged on the U-shaped frame 101 and the sliding component 201, and a connecting component 404 arranged on the extrusion component 403.

[0028] Specifically, the indoor unit of the air conditioner is placed on the hanging plate 105 during installation. The three threaded holes 103 can be replaced with one of the adjacent threads when a problem occurs in the mold opening of a single threaded hole 103. The thickness of the four extension blocks 102 is smaller than that of the U-shaped frame 101, so that the outer end of the bolt will not protrude from the U-shaped frame 101.

[0029] Furthermore, the sliding assembly 201 includes a second slide plate 201a arranged in the U-shaped frame 101, the second slide plate 201a is provided with an installation groove 201b, the installation groove 201b and the U-shaped frame 101 are both provided with a T-shaped groove 201c, and the first slide plate 104 and the second slide plate 201a are both fixedly connected with a T-shaped block 201d that cooperates with the T-shaped groove 201c; the limiting assembly 202 includes a hook fixedly connected to the hanging plate 105, a bearing frame 202b is fixedly connected between the two hooks, the hanging plate 105 is provided with a receiving groove 202c, the receiving groove 202c is provided with an elastic cloth 202d, the elastic cloth 202d is provided with a hook 202e whose thickness is greater than the width of the bearing frame 202b, the hook is fixedly connected with a fixing plate 202f, and the fixing plate 202f is fixedly connected with a mounting ring 202g that cooperates with the hook 202e.

[0030] It should be noted that the lengths of the second slide plate 201a and the first slide plate 104 are both shorter than the length of the U-shaped frame 101, and the T-shaped groove 201c does not completely penetrate the U-shaped frame 101, so that the second slide plate 201a will not be separated from the U-shaped frame 101 (the first slide plate 104 will not be separated from the second slide plate 201a similarly). The hook 202a here cooperates with the air conditioner to fix the air conditioner, and the thickness of the hook 202e is greater than the width of the supporting frame 202b, so as to avoid the buckle moving to the lower end of the supporting frame 202b, making it convenient for workers to pull out the hook 202e to limit the air conditioner.

[0031] When the air conditioner indoor unit is to be installed, the U-shaped frame 101 is first fixed to a designated position on the wall by means of expansion bolts, and then the first slide plate 104 is pulled and pushed to the left, so that the first slide plate 104 and the second slide plate 201a both slide to the left. A damping is provided between the T-shaped block 201d and the T-shaped slot 201c, so that the first slide plate 104 and the second slide plate 201a will not automatically reset. The outer side of the air conditioner duct is extended from the hole on the wall (generally on the wall) to the left. The air conditioner is placed on the hanging plate 105. A bayonet that cooperates with the hanging plate 105 is provided on the air conditioner, so that when the air conditioner is placed on the hanging plate 105, the position of the air conditioner can be automatically limited. This is the prior art and will not be described in detail. The supporting force of the U-shaped frame 101 and the second slide plate 201a is sufficient. When the air conditioner is placed on the hanging plate 105, the first slide plate 104 and the second slide plate 201a will not be caused. 201a, the U-shaped frame 101 is tilted (the expansion bolts driven into the wall here can provide sufficient supporting force and the U-shaped frame 101 will not fall), and then the hook 202e is pulled to make the elastic cloth 202d pass through the front side of the air-conditioning indoor unit, and then the hook 202e cooperates with the mounting ring 202g to limit the position of the air-conditioning outdoor unit, so that when pushing the air-conditioning pipe, even if the air-conditioning pipe is tilted and there is an upward thrust on the air-conditioning indoor unit, it will not push the air-conditioning indoor unit to move upward, causing the air-conditioning indoor unit to detach from the hanging plate 105. After the air-conditioning indoor unit is fixed, the worker moves the stepladder close to the hole, and then pulls the air-conditioning pipe outward by hand. During the process of the air-conditioning pipe moving outward, there is a pulling force on the air-conditioning indoor unit, thereby pulling the air-conditioning indoor unit toward the hole. There is no need for an extra worker to hold the air-conditioning indoor unit for cooperation, and the installation is more convenient. It is worth noting that since the air-conditioning pipe is a copper pipe inside and the copper pipe is fixed to the air-conditioning indoor unit, the air-conditioning pipe will not be separated from the air-conditioning indoor unit when pulling.

[0032] In summary, by setting the bearing component 100 and the extension component 200, when installing the air conditioner indoor unit, it is only necessary to place the air conditioner indoor unit on the hanging plate 105 and then pull the air conditioning pipe. Only one worker is needed to complete this process, which saves manpower and facilitates installation.

[0033] Example 2, reference Figure 1 to Figure 5 , which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides an anti-loosening component 300 of a HVAC fixing device, which solves the problem of how to prevent the first slide plate 104 and the second slide plate 201a from sliding automatically. It includes a one-way component 301, including an extension groove 301a arranged on the inner wall of the T-shaped groove 201c, a plurality of stop blocks 301b are arranged in the extension groove 301a, a clamping block 301c matched with the stop block 301b is provided on the T-shaped block 201d, and a cutting edge 301d is provided at the right end of the clamping block 301c and the left end of the stop block 301b. The elastic component 302 includes a slide groove 302a arranged on the T-shaped block 201d, a slider 302b is slidably connected in the slide groove 302a, the slider 302b is elastically connected to the inner wall of the slide groove 302a through a first spring 302c, and the slider 302b is fixedly connected to the clamping block 301c.

[0034] Specifically, the right end of the block 301c and the left end of the stop block 301b are both provided with a cutting edge 301d, so that the first slide 104 and the second slide 201a will not be blocked when moving to the right, and when moving to the left, since the left end of the block 301c contacts the right end of the stop block 301b, it is a non-cutting edge 301d at this time, so that the block 301c cannot move to the left, the first slide 104 and the second slide 201a will not automatically move to the left, so that the hanging plate 105 will not automatically move to the left, and the air conditioner indoor unit will not automatically move to the left.

[0035] When in use, when the air conditioner outdoor unit moves to the right, the cutting edge 301d on the block 301c first abuts against the cutting edge 301d on the stop block 301b, and at this time, the block 301c can be pushed to move in the direction of the slide groove 302a, so that the slider 302b moves and the first spring 302c is compressed. When the block 301c is completely misaligned with the stop block 301b, under the action of the first spring 302c, the block 301c is reset. At this time, the stop block 301b cooperates with the non-cutting edge 301d of the block 301c to prevent the block 301c from resetting, thereby avoiding the resetting of the first slide plate 104 or the second slide plate 201a. After the first slide plate 104 or the second slide plate 201a moves to the right, it will not automatically move to the left, avoiding Be careful when pushing the air conditioning pipe to avoid the problem of resetting the air conditioning indoor unit. It is worth noting that when the first slide plate 104 and the cutting edge 301d of the second slide plate 201a are against each other, they will also be subject to a certain resistance, thereby slowing down the speed of the air conditioning indoor unit moving to the right, and avoiding the air conditioning indoor unit moving to the rightmost end at a high speed, resulting in a large impulse and causing the U-shaped frame 101 to loosen. At the same time, when the second slide plate 201a and the first slide plate 104 both move to the rightmost end, the stop block 301b cooperates with the cutting edge 301d of the card block 301c, so that the first slide plate 104 and the second slide plate 201a cannot be reset, thereby achieving the fixation of the air conditioning indoor unit. After the air conditioning pipe is extended, the air conditioning indoor unit is automatically fixed, making the installation efficiency higher.

[0036] In summary, by providing the anti-loosening component 300, when the indoor unit of the air conditioner moves to the right, the blocking block 301c on the first slide plate 104 and the T-shaped block 201d on the second slide plate 201a cooperates with the stop block 301b to prevent the blocking block 301c from automatically resetting and the indoor unit of the air conditioner from automatically resetting. When reaching the rightmost end, the indoor unit of the air conditioner can be limited to prevent the indoor unit of the air conditioner from moving left and right.

[0037] Example 3, reference Figure 1 to Figure 7, which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides an unlocking component 400 of the HVAC fixing device, which solves the problem of how to unlock the block 301c and the stop block 301b to facilitate the disassembly of the air conditioner indoor unit. It includes a threaded component 401, including a mounting sleeve 401a fixedly connected to the U-shaped frame 101, a mounting cavity 401b is provided in the U-shaped frame 101, an opening is provided on the inner wall of the mounting cavity 401b, a rotating shaft 401c is rotatably connected in the opening, a threaded rod 401d is fixedly connected to the rotating shaft 401c, a regular hexagonal groove 401e is provided on the rotating shaft 401c, and the mounting sleeve 40 The inner wall of 1a is in contact with the outer wall of the rotating shaft 401c, and the lower end of the mounting sleeve 401a extends to the lower end of the hanging plate 105; the pushing assembly 402 includes a lifting ring 402a threadedly connected to the threaded rod 401d, and a moving ring 402b is provided on the lower side of multiple lifting rings 402a, and guide blocks 402c are provided on the lifting rings 402a and the moving rings 402b, and a guide groove 402d matching the guide block 402c is provided on the inner wall of the mounting cavity 401b, and a notch 402e is provided on the lifting ring 402a and the moving ring 402b, and a transmission shaft is fixedly connected in the notch 402e, and a transmission plate 402f is rotatably connected to the transmission shaft.

[0038] Specifically, the lower end of the mounting sleeve 401a here extends to the lower end of the hanging plate 105, so that the mounting sleeve 401a is easier to find, thereby facilitating the insertion of a screwdriver into the mounting sleeve 401a to rotate the rotating shaft 401c. The setting of the hexagonal groove here can prevent the screwdriver and the rotating shaft 401c from rotating relative to each other when the rotating shaft 401c rotates. At the same time, the mounting sleeve 401a will not extend to the lower side of the air conditioner indoor unit, so as to avoid affecting the overall aesthetics.

[0039] Furthermore, the extrusion assembly 403 includes an expansion slot 403a arranged on the extension slot 301a, a T-shaped supporting plate 403b is slidably connected in the expansion slot 403a, a plurality of stop blocks 301b are fixedly connected to the supporting plate 403b, and the supporting plate 403b is elastically connected to the inner wall of the expansion slot 403a through a second spring 403c; the adapter assembly 404 includes an adapter slot 404a arranged on the U-shaped frame 101 and connected to the expansion slot 403a, a long rod 404b is provided in the adapter slot 404a, three top rods 404c cooperating with the supporting plate 403b are fixedly connected to the long rod 404b, and a support rod 404d fixed to the long rod 404b is fixedly connected to the movable ring 402b.

[0040] It should be noted that the second spring 403c and the push rod 404c are arranged on both sides of the supporting plate 403b, so that there will be no problem of jamming between the second spring 403c and the push rod 404c. The three long rods 404b are respectively arranged at the leftmost end, the rightmost end and the middle position of the supporting plate 403b, so as to ensure that when the supporting plate 403b moves, the push rod 404c can always be against the supporting plate 403b.

[0041] When in use, the second spring 403c is first in a compressed state. When the indoor unit of the air conditioner needs to be disassembled, the fixation between the air conditioner pipe and the outdoor unit of the air conditioner is first released, and then a bolt driver (the screwdriver here refers to a screwdriver with a hexagonal screwdriver head, the same below) is inserted into the installation sleeve 401a. The lower end of the installation sleeve 401a here extends to the lower end of the hanging plate 105. Therefore, when searching, it is only necessary to move the screwdriver left and right to let the screwdriver collide with the installation sleeve 401a to accurately find the position of the installation sleeve 401a, and then insert the screwdriver into the hexagonal groove and rotate it to rotate the shaft 401c. When the shaft 401c rotates, it can drive the threaded rod to rotate, so that the lifting ring 402a moves downward. When the lowering ring 402a moves downward, the moving ring 402b is driven to move backward through the transmission plate 402f. When the moving ring 402b moves backward, it drives the support rod 404d to move backward, the long rod 404b moves backward, and then the top rod 404c moves backward. Under the action of the second spring 403c, the bearing plate 403b moves backward, so that the stop block 301b is disengaged from the clamping block 301c. At this time, the T-shaped block 201d can be moved at will, so that the first slide plate 104 and the second slide plate 201a can be moved, and then the air-conditioning indoor unit can be moved to the left, so that the air-conditioning pipe slowly enters the room from the hole, and then the air-conditioning indoor unit can be removed to pull out the air-conditioning pipe, and the disassembly is completed.

[0042] In summary, by setting the unlocking component 400, when it is necessary to disassemble the indoor unit of the air conditioner, it is only necessary to rotate the rotating shaft 401c with a screwdriver to separate the blocking block 301c from the stop block 301b through transmission. At this time, the indoor unit of the air conditioner can be moved so that there is enough space for the air-conditioning pipe to be delivered from the outside end to the indoor room, and then the indoor unit of the air conditioner can be removed to complete the disassembly process.

[0043] It needs to be explained that although two people are usually required to install the air conditioner because high-altitude work is required to install the outdoor unit, some outdoor units are in air-conditioning shafts with shutters and do not require high-altitude work. In this case, two people are not needed. At this time, the device of the present invention can play a greater role, and one person can complete the entire installation process.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
