Description

Technical Field

[0001] This utility model belongs to the field of air supply ceiling technology, specifically relating to a clean air supply ceiling with adjustable air direction. Background Technology

[0002] In industries with extremely high requirements for environmental cleanliness, such as modern medical care, pharmaceuticals, electronics manufacturing, and precision machining, the design and construction of cleanrooms are crucial for ensuring product quality and production safety.

[0003] However, in existing cleanroom air supply ceilings, the air supply direction is mostly vertically downward or fixed at a preset angle, which cannot be dynamically adjusted according to the actual needs of different areas in the cleanroom, resulting in poor applicability. Furthermore, the perforated plates are often fixed to the air supply ceiling by bolts or welding, requiring the disassembly of a large number of surrounding structures when replacing them, making it inconvenient to replace the perforated plates on the ceiling. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable airflow cleanroom ceiling to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable airflow cleanroom ceiling includes an airflow ceiling body, a base plate fixed to the lower side of the airflow ceiling body, a plurality of mounting seats provided in the middle of the base plate, a perforated plate installed on the inner side of the mounting seats, a fixed frame hinged to the lower side of the base plate, two sets of vertically distributed airflow adjustment mechanisms installed on the upper side of the fixed frame, a rotating rod vertically rotatably mounted on the front side of the fixed frame, a fixing lug fixed on the upper side of the rotating rod, a fixing hole matching the fixing lug opened on the upper side of the base plate, and a control handle fixed on the lower side of the rotating rod;

[0007] The wind direction adjustment mechanism includes multiple evenly spaced wind guide plates that are hinged to the fixed frame. The sides of the wind guide plates in the same group are connected to a synchronous rod. The side of the fixed frame is fixed with a wind direction adjustment component that is connected to one of the wind guide plates.

[0008] The rotating rods are numerous and evenly distributed on the upper side of the fixed frame. Except for the rotating rods on the rear side, each rotating rod has a fixed lug on its upper side. The fixed frame is a hollow structure. A synchronous pulley is fixed in the middle of each rotating rod. A synchronous belt is connected to the outer side of the multiple synchronous pulleys for transmission. Multiple abutment blocks that match the synchronous pulleys and the synchronous belt are fixed inside the fixed frame.

[0009] The wind direction adjustment mechanism includes a housing fixed by the fixed frame, a worm gear rotatably mounted on the inner side of the housing and driven by the wind guide plate, a worm gear meshing with the worm gear rotatably mounted on the side of the worm gear, and a motor driven by the worm gear mounted on the side of the housing.

[0010] The mounting base is a metal mounting base, and a magnet ring is fixed to the outside of the perforated plate.

[0011] A rubber pad that matches the magnet ring is fixed inside the mounting base.

[0012] This air supply ceiling system utilizes two sets of vertically distributed airflow adjustment mechanisms. These mechanisms, through multiple air guide plates, synchronous rods, and airflow adjustment components, allow the air guide plates to rotate synchronously in the same direction, enabling independent or coordinated adjustment of the airflow direction. This design enhances its applicability to different areas within the cleanroom. The perforated plate is installed inside the mounting base and above the fixed frame, which is secured by fixing ears and holes. This design allows for easy unlocking by simply rotating the control handle, which drives the fixing ears to rotate. The fixed frame can then be opened downwards for quick replacement of the perforated plate, significantly reducing downtime and improving the ease of use of the air supply ceiling system. The synchronous pulleys and belts allow the control handle to simultaneously control the synchronous rotation of multiple rotating rods, and can be used with multiple... The fixed ears ensure a more stable fixation of the frame, while the abutment block prevents the timing pulley and belt from slipping or skipping, guaranteeing reliability. The worm gear features one-way self-locking and torque amplification, reducing motor load. This design makes the airflow adjustment mechanism simple and reliable, while also reducing overall size and improving the aesthetics and integrity of the air supply ceiling. The magnetic ring and metal mounting base allow the perforated plate to automatically adhere to the underside of the mounting base during installation, improving ease of installation. The rubber pad increases the gap between the perforated plate and the air supply ceiling body, enhancing the overall sealing performance of the air supply ceiling and helping to prevent vibration noise, thus improving its quietness.

Detailed Implementation

[0023] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] like Figure 1-8 As shown, a cleanroom ceiling with adjustable airflow direction includes an air supply ceiling body 1, a base plate 2 fixed to the lower side of the air supply ceiling body 1, a plurality of mounting seats 3 provided in the middle of the base plate 2, a perforated plate 4 installed inside the mounting seats 3, a fixed frame 5 hinged to the lower side of the base plate 2, two sets of vertically distributed airflow adjustment mechanisms installed on the upper side of the fixed frame 5, a rotating rod 6 vertically rotatably mounted on the front side of the fixed frame 5, a fixed ear 7 fixed on the upper side of the rotating rod 6, a fixed hole 8 matching the fixed ear 7 opened on the upper side of the base plate 2, and a control handle 9 fixed on the lower side of the rotating rod 6.

[0025] The wind direction adjustment mechanism includes multiple wind guide plates 10 that are evenly spaced and hinged to the fixed frame 5. The sides of the wind guide plates 10 in the same group are connected to a synchronous rod 11. The side of the fixed frame 5 is fixed with a wind direction adjustment component that is connected to one of the wind guide plates 10.

[0026] The air supply ceiling uses two sets of vertically distributed airflow adjustment mechanisms. These mechanisms, along with multiple air guide plates 10, a synchronizing rod 11, and an airflow adjustment assembly, allow the air guide plates 10 to rotate synchronously in the same direction. This enables independent or coordinated adjustment of the airflow direction, improving its applicability to different areas within the cleanroom. The perforated plate 4 is installed inside the mounting base 3 and located on the upper side of the fixed frame 5. The fixed frame 5 is fixed to the fixed holes 8 via fixed ears 7. This design allows the fixed ears 7 to be rotated simply by turning the control handle 9 to unlock the system. The fixed frame 5 can then be opened downwards for quick replacement of the perforated plate 4, significantly reducing downtime and improving the ease of use of the air supply ceiling.

[0027] There are multiple rotating rods 6 evenly distributed on the upper side of the fixed frame 5. Except for the rotating rods 6 on the rear side, each rotating rod 6 has a fixed lug 7 fixed on its upper side. The fixed frame 5 is a hollow structure. Each rotating rod 6 has a synchronous pulley 12 fixed in the middle. The outer sides of the multiple synchronous pulleys are connected to a synchronous belt 13 for transmission. The inner side of the fixed frame 5 has multiple abutment blocks 14 that match the synchronous pulleys and the synchronous belt 13.

[0028] The cooperation between the synchronous pulley and the synchronous belt 13 allows the control handle 9 to control multiple rotating rods 6 to rotate synchronously at the same time. The combination of multiple fixing ears 7 makes the fixing frame 5 more stable. The abutment block 14 can prevent the synchronous pulley and the synchronous belt 13 from skipping teeth and slipping, thus ensuring its reliability.

[0029] The wind direction adjustment mechanism includes a housing 15 fixed by a fixed frame 5, a worm gear 16 rotatably mounted inside the housing 15 and connected to the wind guide plate 10, a worm 17 meshing with the worm gear 16 rotatably mounted on the side of the worm gear 16, and a motor 18 connected to the worm 17 rotatably mounted on the side of the housing 15.

[0030] The worm gear 16 and worm 17 have one-way self-locking characteristics and torque amplification characteristics, which can reduce the burden on the motor 18. This setting makes the air direction adjustment mechanism simple and reliable, while also helping to reduce the overall size and improve the aesthetics and integrity of the air supply ceiling.

[0031] Mounting base 3 is a metal mounting base 3, and a magnet ring 19 is fixed on the outside of the perforated plate 4.

[0032] A rubber pad 20 matching the magnet ring 19 is fixed inside the mounting base 3.

[0033] The magnetic ring 19 cooperates with the metal mounting base 3 so that the perforated plate 4 can be automatically adsorbed on the underside of the mounting base 3 during installation, which improves the convenience of installation of the perforated plate 4. The rubber pad 20 can increase the gap between the perforated plate 4 and the air supply ceiling body 1, improve the overall sealing performance of the air supply ceiling, and also help to avoid vibration noise and improve the sound insulation performance of the air supply ceiling.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
