Description

Technical Field

[0001] This utility model relates to the field of HVAC outdoor unit technology, and in particular to a protective component for HVAC outdoor unit. Background Technology

[0002] In modern building environments, HVAC outdoor units, as key equipment for regulating indoor temperature and humidity, are constantly exposed to the complex outdoor environment, making them susceptible to factors such as wind, rain, dust, ultraviolet radiation, and external impacts, leading to decreased operating efficiency and shortened lifespan. To ensure stable operation of these units, various protective components have emerged. Their main function is to provide a physical barrier for the outdoor units, reducing the corrosive effects of the external environment and preventing damage from human or accidental factors. Currently, there are many types of protective components for HVAC outdoor units on the market, but their structural design and installation methods directly affect the protective effect and ease of use. Therefore, the optimized design of protective components has always been a key research focus in the industry.

[0003] In existing technologies, protective components for HVAC outdoor units typically employ a frame structure, consisting of a protective plate made of metal or high-strength plastic combined with a mounting bracket. The technical principle generally involves rigidly fixing the protective plate to the bracket using bolts, nuts, and other connectors. Some components have multiple pre-drilled mounting holes on the bracket to accommodate the mounting requirements of units of different sizes. Furthermore, some protective components incorporate a perforated design on the surface of the protective plate, ensuring protective effectiveness while minimizing impact on the unit's heat dissipation function. The stability of the mechanical connection achieves long-term protection for the outdoor unit.

[0004] However, the existing technology presents significant inconveniences in the assembly and disassembly of protective panels. Since the protective panels are mostly fixed to the brackets using rigid connectors such as bolts, disassembly or relocation requires the use of multiple tools, such as wrenches and screwdrivers, to tighten each connector individually, making the process cumbersome and time-consuming. This is especially problematic in outdoor environments where carrying tools is difficult, further increasing the difficulty of assembly and disassembly, resulting in inefficient movement and reinstallation of the protective panels and causing considerable inconvenience to users. Therefore, a protective component for HVAC outdoor units is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a protective component for HVAC outdoor units, which aims to improve the problem that the existing technology requires multiple tools to disassemble and reassemble the protective plate, making it difficult to disassemble conveniently.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A protective component for an outdoor unit of a heating, ventilation and air conditioning system includes a base, a plurality of columns fixedly connected to the top of the base, a protective plate between two columns, a limit component inside the columns, a top plate on the top of the columns, and a splicing component inside the columns. The limiting component includes a limiting plate, the outer wall of which is disposed on the outer wall of the column. A groove is formed inside the column, and the outer wall of the protective plate is slidably connected to the groove. A slot is formed inside the column. A limiting post is fixedly connected to the bottom of the limiting plate, and the outer wall of the limiting post is slidably connected to the slot. A connecting post is fixedly connected to the bottom of the limiting plate, and the outer wall of the connecting post is slidably connected to the inside of the column. A limiting disc is rotatably connected to the bottom of the connecting post, and a reset component is sleeved on the outer wall of the connecting post.

[0007] As a further description of the above technical solution: The reset assembly includes a spring, which is sleeved inside the outer wall of the connecting column. The top end of the spring is fixedly connected to the inner wall of the column, and the bottom end of the spring is fixedly connected to the top of the limiting disc.

[0008] As a further description of the above technical solution: The splicing component includes a locking block, the outer wall of which is slidably connected to the inside of the column.

[0009] As a further description of the above technical solution: A fixed column is fixedly connected to the bottom of the top plate, and a fixed cone is fixedly connected to the bottom end of the fixed column.

[0010] As a further description of the above technical solution: The fixed cone fits into the card block, and a limit plate is fixedly connected to the bottom of the card block.

[0011] As a further description of the above technical solution: The column has a limiting groove inside, and the outer wall of the limiting plate is slidably connected to the limiting groove.

[0012] As a further description of the above technical solution: A second spring is installed inside the column. One end of the second spring is fixedly connected to the outer wall of the limiting plate, and the other end of the second spring is fixedly connected to the inner wall of the limiting groove.

[0013] As a further description of the above technical solution: A pull rod is fixedly connected to the outer wall of the limiting plate, and a limiting disc is fixedly connected to the outer wall of the pull rod. The limiting disc is in contact with the outer wall of the column, and a pull ring is rotatably connected to the outer wall of the pull rod.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the limiting plate achieves its lifting function by pulling. When the limiting plate is pulled, the limiting plate drives the connecting column and the limiting disc, and in conjunction with the spring, the limiting column slides inside the slot, thereby facilitating the limiting assembly of the protective plate and making it easy to fix and move. This solves the problem that multiple tools are needed to disassemble the protective plate, which makes it difficult to disassemble. It also improves the convenience of placing the protective plate.

[0015] 2. In this utility model, the locking block achieves its movement function by pulling the pull ring. When the pull ring is pulled, the pull ring drives the pull rod and the limiting plate, and in conjunction with the second spring, the locking block slides inside the column, thereby facilitating the splicing and placement of the top plate and making it convenient to connect different devices. This solves the problem of not being able to easily splice multiple protective components and improves the flexibility of the device. Attached Figure Description

[0019] Reference Figures 1-3 This utility model provides an embodiment of a protective component for an outdoor unit of a heating, ventilation, and air conditioning system. The component includes a base 1, which is a rectangular welded steel plate structure with anti-slip feet welded to the four corners at the bottom. Rubber pads are attached to the bottom of the feet to increase friction with the ground and prevent displacement of the protective component due to vibrations during unit operation, thereby enhancing overall installation stability. Multiple uprights 2 are fixedly connected to the top of the base 1. The uprights 2 are hollow square tube structures made of Q235 low-carbon steel, possessing high strength and toughness, capable of withstanding the weight of the protective plate 4 and the top plate 3, as well as external impact forces. This is common knowledge and will not be elaborated further here. Between two uprights 2... A protective plate 4 is provided, which consists of an outer galvanized steel plate and an inner sound insulation cotton. The galvanized steel plate is 1.2mm thick and has good rust resistance. The sound insulation cotton is made of polyester fiber and is used to reduce the noise generated during the operation of the unit and achieve noise reduction. This will not be elaborated on here. The column 2 is equipped with a limit component inside. The top of the column 2 is equipped with a top plate 3, which is a trapezoidal structure and made of transparent polycarbonate sheet. It has UV resistance and impact resistance and is used to block rainwater, fallen leaves and other debris from falling into the unit, while not affecting sunlight. This is common knowledge and will not be elaborated on here. The column 2 is equipped with splicing components inside. The limiting assembly includes a limiting plate 5, which is formed by stamping steel plate with rounded edges to prevent hand injuries during operation. The outer wall of the limiting plate 5 is set on the outer wall of the column 2. A groove 11 is formed inside the column 2. The outer wall of the protective plate 4 is slidably connected to the groove 11. A slot 10 is formed inside the column 2. A limiting post 9 is fixedly connected to the bottom of the limiting plate 5. The limiting post 9 has a stepped shaft structure with a diameter matching the inner diameter of the slot 10. The outer wall of the limiting post 9 is slidably connected to the slot 10. When the limiting post 9 is inserted into the slot 10, it is used to... To prevent the protective plate 4 from sliding within the slide groove 11, thereby locking the protective plate 4, the outer wall of the limiting post 9 is slidably connected to the inside of the slot 10, the bottom of the limiting plate 5 is fixedly connected to the connecting post 8, the outer wall of the connecting post 8 is slidably connected to the inside of the column 2, the bottom of the connecting post 8 is rotatably connected to the limiting disc 6, the outer wall of the connecting post 8 is fitted with a reset assembly, the reset assembly includes a spring 7, the spring 7 is fitted inside the outer wall of the connecting post 8, the top end of the spring 7 is fixedly connected to the inner wall of the column 2, and the bottom end of the spring 7 is fixedly connected to the top of the limiting disc 6.

[0020] Reference Figure 1 , Figure 4 and Figure 5The splicing assembly includes a locking block 16, which is a wedge-shaped structure made of 45# steel and hardened. It engages with a fixed cone 17 to restrict its movement, preventing the top plate 3 or protective device from loosening after splicing and ensuring connection stability. The outer wall of the locking block 16 is slidably connected to the inside of the column 2. A fixed column 13 is fixedly connected to the bottom of the top plate 3, and a fixed cone 17 is fixedly connected to the bottom end of the fixed column 13. The fixed cone 17 fits against the locking block 16. A limit plate 18 is fixedly connected to the bottom of the locking block 16. A limit groove 19 is formed inside the column 2 to limit the sliding direction of the limit plate 18 and prevent it from moving. The positioning plate 18 shifts during movement to ensure the accuracy of the movement of the locking block 16. The outer wall of the positioning plate 18 is slidably connected to the inside of the positioning groove 19. A second spring 15 is installed inside the column 2. One end of the second spring 15 is fixedly connected to the outer wall of the positioning plate 18, and the other end of the second spring 15 is fixedly connected to the inner wall of the positioning groove 19. A pull rod 20 is fixedly connected to the outer wall of the positioning plate 18. The pull rod 20 is a round rod structure made of high-strength alloy material with good tensile strength. It is used to drive the positioning plate 18 to move. A positioning disc 14 is fixedly connected to the outer wall of the pull rod 20. The positioning disc 14 fits against the outer wall of the column 2. A pull ring 12 is rotatably connected to the outer wall of the pull rod 20.

[0021] Working principle: When installing the protective plate 4, the limiting plate 5 must be manually pulled first. At this time, the limiting plate 5 will simultaneously drive the connecting column 8 to rise and fall vertically. The limiting disc 6 fixed at the other end of the connecting column 8 will slide within the cavity, thereby compressing the spring 7 sleeved on the outside of the connecting column 8, causing the spring 7 to be in an energy storage state. As the limiting disc 6 moves, the limiting post 9 connected to the limiting plate 5 gradually slides out from inside the slot 10, releasing the lock on the installation path of the protective plate 4.

[0022] Then, rotate the limiting plate 5 to the preset angle to fully expose the previously obscured slide 11. At this point, the protective plate 4 can be inserted horizontally into the slide 11, ensuring that the edge of the protective plate 4 fits tightly against the inner wall of the slide 11. After insertion, rotate the limiting plate 5 back to its initial position and slowly release it. The compressed spring 7 releases its elastic potential energy, pushing the limiting disc 6 and connecting post 8 to reset, thus returning the limiting plate 5 to its original position. The limiting post 9 then re-engages into the slot 10, firmly fixing the protective plate 4 through the mechanical locking structure. This forms a stable barrier around the device, providing all-around protection for the HVAC outdoor unit.

[0023] When splicing the top plate 3 or multiple protective devices, the operation process is equally convenient. Pulling the pull ring 12 causes the limit plate 18 to slide horizontally within the limit groove 19 via the rigidly connected pull rod 20. During the movement of the limit plate 18, the spring 15 is compressed, causing it to contract and store energy. At this time, the fixed cone 17 is released from the lock of the latch 16 and slides into the reserved space inside the column 2. After the fixed cone 17 is aligned with the docking component, the pull ring 12 is released, and the spring 15 quickly rebounds, pushing the limit plate 18 and pull rod 20 to reset. The latch 16 then returns to its initial position and precisely engages with the groove on the surface of the fixed cone 17. The continuous pressure generated by the elastic reset maintains the connection stability, quickly completing the splicing and assembly of multiple components.

[0024] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
