Description

Technical Field

[0001] The utility model relates to the technical field of air-conditioning installation, in particular to a heating, ventilation and air-conditioning installation structure. Background Art

[0002] Heating, ventilation, and air conditioning (HVAC) systems are an integral part of modern buildings, ensuring a comfortable indoor environment. The core functions of this system include heating, ventilation, and air conditioning, or HVAC for short. Heating, typically achieved through boilers, heat pumps, or electric heaters, ensures a comfortable indoor temperature during cold weather. Ventilation systems are designed to provide fresh air, remove pollutants, and maintain indoor air quality. Air conditioning, primarily through refrigeration equipment such as air conditioning units, reduces indoor temperatures and creates a cool environment.

[0003] Heating, ventilation, and air conditioning (HVAC) systems are used in a wide range of applications, from residential and office buildings to shopping malls and industrial facilities. Furthermore, modern HVAC systems emphasize energy conservation and environmental protection, using advanced control technologies and energy-efficient equipment to reduce energy consumption and environmental impact.

[0004] At present, HVAC fans are generally installed using screws. The specific method is to fix the expansion bolts to the ceiling, then install the screws on the expansion bolts, and then install the air conditioner on the screws through nuts. There are two nuts on each bolt, and the mounting plate on the air conditioner fan is clamped by the nuts.

[0005] This installation method has some drawbacks. First, current air conditioners generally use four screws for suspension. During installation, eight nuts need to be tightened, which is inconvenient. Second, when tightening, the nuts need to be screwed into a preset position. The nuts need to be rotated to install on the screws, which affects installation efficiency. Therefore, this application proposes a HVAC installation structure. Utility Model Content

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0036] Figures 1 to 3 As shown, an embodiment of the present invention provides a HVAC installation structure, the installation structure comprising:

[0037] The outer shell 10 is cylindrical with openings at both ends, and an inner retaining ring is provided at one end of the outer shell 10;

[0038] A limiting tube 20, the limiting tube 20 is fixedly connected to the end of the housing 10 away from the inner retaining ring, and the inner side of the end of the limiting tube 20 disposed in the housing 10 is provided with a conical bell mouth;

[0039] A conical nut 30, wherein the outer side of the conical nut 30 is a conical surface, a threaded hole is provided at the center of the conical nut 30, and the conical nut 30 is divided into two parts along its axis to form a first half nut 31 and a second half nut 32. The conical nut 30 is located in the flare, and the mouths of both ends of the conical nut 30 are conical openings;

[0040] A bottom support 40 is provided in the housing 10 and is located between the conical nut 30 and the inner retaining ring, with an end of the bottom support 40 located at the conical opening;

[0041] A compression spring 50 is sleeved on the bottom support 40 , with both ends of the compression spring 50 respectively abutting against the end of the conical nut 30 and the end of the bottom support 40 , and the compression spring 50 applies a thrust to the conical nut 30 away from the bottom support 40 ;

[0042] The top pressure tube 60 is located on the side of the conical nut 30 away from the bottom support 40, and the end of the top pressure tube 60 is located in the conical opening. The inner diameter of the bottom support 40 and the top pressure tube 60 is larger than the aperture of the inner threaded hole of the conical nut 30.

[0043] In this embodiment, the mounting structure is fixed to the air conditioner. When installing the air conditioner, the screw for suspension is still fixed to the ceiling in the traditional way, and the position of the top pressure tube 60 is adjusted so that the top pressure tube 60 presses the conical nut 30. Since the supporting conical end 41 cooperates with the conical opening in the conical nut 30, the supporting conical end 41 fixes the conical nut 30, so that the first half nut 31 and the second half nut 32 move away from each other, and the inner diameter of the conical nut 30 is expanded. At this time, the air conditioner is lifted and the screw is inserted into the conical nut 30. After adjusting the position of the air conditioner, the top is adjusted again. The position of the pressing tube 60 causes the top pressing tube 60 to disengage from the conical nut 30. The conical nut 30 moves toward the inner side of the limiting tube 20 under the thrust of the compression spring 50. The bell mouth in the limiting tube 20 squeezes the outer side of the conical nut 30, so that the two first half nuts 31 are close to each other. The first half nut 31 and the second half nut 32 are pressed onto the screw. After the air conditioner is loosened, the screw applies axial tension to the conical nut 30, so that the first half nut 31 and the second half nut 32 are tightened in the bell mouth. The first half nut 31 and the second half nut 32 clamp the screw, thereby fixing the air conditioner to the screw.

[0044] The HVAC installation structure disclosed in the embodiment of the present invention clamps the screw through the first half nut 31 and the second half nut 32 which can move away from and approach each other when installing the air conditioner, and converts the pulling force of the screw into an extrusion force that moves the first half nut 31 and the second half nut 32 closer to each other through the limiting tube 20. At the same time, the threads on the inner sides of the first half nut 31 and the second half nut 32 cooperate with the threads of the screw, so that the first half nut 31 and the second half nut 32 can provide sufficient force to fix the air conditioner. Compared with the traditional structure, the present invention has the advantages of easy and quick installation.

[0045] Specifically, in this embodiment, Figures 1 to 3 As shown, the outer shell 10 is cylindrical with openings at both ends, the inner retaining ring of the outer shell 10 is an integral structure with the outer shell 10, and a mounting end 11 is provided on the outer side of the outer shell 10. The mounting end 11 can be installed according to the structure of the air conditioner. In this embodiment, the mounting end 11 is an ear-shaped mounting plate. In some other structures, the mounting end 11 can also be a flange structure. For air-conditioning fans with heavier weight, a flange structure can be used to improve the reliability of the mounting structure.

[0046] As a preferred implementation of this embodiment, the shell 10 and the limiting tube 20 are connected by threads, the inner side of the shell 10 is provided with an internal thread, the outer side of the limiting tube 20 is provided with an external thread, and thread glue is also provided between the shell 10 and the limiting tube 20, so that the shell 10 and the limiting tube 20 cannot rotate relative to each other after installation.

[0047] Preferably, a limiting structure is provided between the bell mouth of the limiting tube 20 and the outer side of the conical nut 30 to prevent the conical nut 30 from rotating in the limiting tube 20;

[0048] Preferably, the flared mouth of the limiting tube 20 forms a hexagonal frustum-shaped cavity, the outer side of the tapered nut 30 forms a hexagonal frustum-shaped cavity, the dividing line between the first half nut 31 and the second half nut 32 is the opposite edge of the hexagonal frustum, and the hexagonal frustum-shaped structure refers to a frustum-shaped structure, both end faces of which are regular hexagons, so that the tapered nut 30 will not rotate in the limiting tube 20;

[0049] It should be noted that although there is friction between the conical nut 30 and the bell mouth, and the squeezing force between the first half nut 31 and the second half nut 32 also generates a self-locking force of the threaded structure, vibration will still occur between the conical nut 30 and the screw when the air conditioner is in operation. To improve the reliability of the installation structure, the inner wall of the bell mouth is processed into a hexagonal frustum-shaped cavity and the outer side of the conical nut 30 is formed into a hexagonal frustum-shaped cavity, thereby preventing the conical nut 30 from rotating.

[0050] In this embodiment, the limiting structure may also be in other forms, such as the bell mouth and the outer side of the conical nut 30 being configured as friction surfaces, or a structure of a limiting block and a fiber groove.

[0051] Preferably, Figure 4 、 Figure 5 and Figure 6 As shown, the first half nut 31 is further fixedly connected to a limiting rod 33, and the second half nut 32 is provided with a limiting hole 34, and the limiting rod 33 is slidably connected in the limiting hole 34;

[0052] In this embodiment, a fixing hole is provided on the first half nut 31, and the limiting rod 33 is fixed to the fixing hole by an interference connection. The limiting rod 33 and the fixing hole are clearance-fitted. The limiting rod 33 is provided on a side of the first half nut 31 that is attached to the second half nut 32, and the limiting hole 34 is provided on a side of the second half nut 32 that is attached to the first half nut 31.

[0053] As a preferred implementation in this embodiment, the end of the top pressing tube 60 is provided with a pressing tube conical end 61. When the top pressing tube 60 presses the conical nut 30, the pressing tube conical end 61 cooperates with the opening of the bottom support 40 to support the conical nut 30, so that both ends of the conical nut 30 have a supporting force, which can prevent the conical nut 30 from being supported at only one end.

[0054] like Figure 7 As shown, the bottom support 40 includes a supporting conical end 41, a limiting plate 42 and a connecting section 43. The limiting plate 42 is annular. The connecting section 43 is located between the supporting conical end 41 and the limiting plate 42. The supporting conical end 41, the limiting plate 42 and the connecting section 43 are an integrated structure. The supporting conical end 41, the limiting plate 42 and the connecting section 43 are concentrically arranged. The outer contour of the supporting conical end 41 is a frustum. The limiting plate 42 is a stepped ring. The compression spring 50 is sleeved on the limiting plate 42. The end of the compression spring 50 away from the limiting plate 42 abuts against the end of the conical nut 30.

[0055] In this embodiment, the connection relationship between the top pressure tube 60 and the limiting tube 20 can be various, such as a damping sliding connection between the top pressure tube 60 and the limiting tube 20, so that the top pressure tube 60 can slide along its axis in the limiting tube 20, such as a sliding connection between the top pressure tube 60 and the limiting tube 20, and the top pressure tube 60 needs to be pressed before installation;

[0056] Another example Figure 3 and Figure 8 As shown, the top pressing tube 60 and the limiting tube 20 are connected by threads. The outer side of the top pressing tube 60 is provided with a limiting thread 62, and the limiting tube 20 is provided with an internal thread. When the conical nut 30 is pressed, the top pressing tube 60 is rotated;

[0057] Preferably, when the top pressure tube 60 and the limiting tube 20 are connected by threads, the end of the top pressure tube 60 away from the conical nut 30 is provided with a hexagonal end 63, and the hexagonal end 63 facilitates the use of tools such as a wrench to rotate the top pressure tube 60.
