Description

Technical Field

[0001] This utility model relates to the field of return air louver technology, and in particular to a door hinge type return air louver. Background Technology

[0002] Return air louvers are terminal devices used in air conditioning or ventilation systems. They are mainly used to adjust the airflow direction, control the air volume, and facilitate the cleaning and replacement of filters. They are commonly found in cleanrooms, dust-free workshops, and other places. Return air louvers are a type of air outlet used for return air in ventilation systems. They are usually composed of adjustable blades that can control the airflow direction and air volume.

[0003] However, most current return air louvers are integral structures, and the air blows directly through the guide of the louver. Therefore, when dust particles are mixed in with the blown air, it is impossible to process the dust particles. To address this issue, we propose a hinged return air louver. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a hinged return air louver.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A hinged return air louver includes a main frame, a purification mechanism is placed inside the main frame, the purification mechanism includes a fixed frame, a filter pad is provided inside the fixed frame, a plug-in frame is fixedly connected to the back of the fixed frame, a connecting frame is fixedly connected to the inner wall of the main frame, a hinged louver frame is hingedly installed on the outer side of the main frame, and a limit mechanism is installed at the end of the hinged louver frame away from the hinge.

[0006] Preferably, both the plug-in frame and the connecting frame have rectangular cross-sections, and the connecting frame has a groove that matches the plug-in frame.

[0007] Preferably, a first magnetic strip is glued to the end of the plug frame, and a second magnetic strip is glued to the inner wall of the groove.

[0008] Preferably, the limiting mechanism includes mounting bolts, and a U-shaped plate is mounted on the surface of the hinged louver frame by the mounting bolts. The inner wall of the U-shaped plate is welded to one end of the return spring, and the other end of the return spring is welded to the surface of the fixing block. The fixing block is sleeved on the surface of the plug rod.

[0009] Preferably, the plug rod is cylindrical, the inner side of the main frame has a slot adapted to the plug rod, and the U-shaped plate has a circular hole adapted to the plug rod.

[0010] Preferably, a limiting block is fixedly connected to the end of the plug rod, and the surface diameter of the limiting block is larger than the surface diameter of the plug rod.

[0011] Preferably, a pull rod is fixedly connected to the surface of the fixing block, and a strip-shaped through groove adapted to the pull rod is opened in both the U-shaped plate and the hinged louver frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device filters and purifies the air flowing within the main frame by placing the fixed frame and filter pad inside the main frame. The fixed frame drives the insertion frame to be inserted into the connecting frame, which facilitates the attraction between the first and second magnetic strips. This effectively limits the function of the fixed frame and prevents it from falling off during the opening of the hinged louver frame.

[0013] 2. By pulling the pull rod, the device can easily move the fixed block along the U-shaped plate to open the hinged louver frame. The spring force of the return spring can reset the plug rod and insert it into the inner side of the main frame, which can limit the position between the main frame and the hinged louver frame. At the same time, the mounting bolts pass through the U-shaped plate and connect to the surface of the hinged louver frame, which can facilitate the assembly and disassembly of the U-shaped plate.

The fixed frame 31 and the filter pad 32 can easily filter and purify the air blown out of the main frame 1. A plug-in frame 33 is fixedly connected to the back of the fixed frame 31, a connecting frame 35 is fixedly connected to the inner wall of the main frame 1, and a hinged louver frame 2 is hingedly installed on the outer side of the main frame 1. A limit mechanism 4 is installed at the end of the hinged louver frame 2 away from the hinge.

[0018] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the cross-section of both the plug frame 33 and the connecting frame 35 is set as a rectangular frame. The connecting frame 35 has a groove that matches the plug frame 33. Through the groove in the connecting frame 35, the fixing frame 31 can easily drive the plug frame 33 into the groove, which facilitates the positioning and installation of the fixing frame 31.

[0019] Furthermore, refer to Figure 1 and Figure 2 It can be seen that the end of the plug frame 33 is glued with a first magnetic strip 34, and the inner wall of the groove is glued with a second magnetic strip 36. The first magnetic strip 34 and the second magnetic strip 36 attract each other, which can facilitate the function of limiting the installation of the fixing frame 31.

[0020] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the limiting mechanism 4 includes mounting bolts 41. A U-shaped plate 42 is mounted on the surface of the hinged louver frame 2 by mounting bolts 41. The inner wall of the U-shaped plate 42 is welded to one end of the return spring 43, and the other end of the return spring 43 is welded to the surface of the fixing block 44. Through the elastic force of the return spring 43 itself, the fixing block 44 and the plug rod 45 can be easily pushed. The fixing block 44 is sleeved on the surface of the plug rod 45.

[0021] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the plug rod 45 is cylindrical, and the inner side of the main frame 1 is provided with a slot that matches the plug rod 45. By inserting the plug rod 45 into the slot, the function of limiting the hinged louver frame 2 can be conveniently defined. The U-shaped plate 42 is provided with a round hole that matches the plug rod 45. By the round hole in the U-shaped plate 42, the plug rod 45 can be conveniently moved along the round hole.

[0022] Furthermore, refer to Figure 3 and Figure 4 It can be seen that the end of the plug rod 45 is fixedly connected to the limiting block 46, and the surface diameter of the limiting block 46 is larger than the surface diameter of the plug rod 45. The limiting block 46 can conveniently limit the function of the plug rod 45.

Pulling the pull rod 47 can cause the fixing block 44 to drive the plug-in rod 45 to retract into the U-shaped plate 42, and compress the return spring 43. At this time, the hinged louver frame 2 is inserted into the main frame 1, and the pull rod 47 is released. At this time, the fixing block 44 can push the plug-in rod 45 to return to its original position through the elastic force of the return spring 43, which facilitates the insertion of the plug-in rod 45 into the slot opened in the inner wall of the main frame 1, which facilitates the function of limiting the installation of the hinged louver frame 2. Thus, the air flowing in the main frame 1 can be filtered through the fixing frame 31 and the filter pad 32. The above is the complete working principle of this utility model.
