Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an integrated air outlet blade fixing frame structure. Background Technology
[0002] In various air conditioning and ventilation systems involving air circulation regulation, the air outlet is a crucial component, directly affecting the direction, range, and uniformity of air output. The air outlet blade fixing frame structure serves as an important component for supporting and securing the air outlet blades.
[0003] Currently, most air outlet blade fixing frames on the market adopt a split assembly structure, or use fasteners such as bolts and screws to connect and fix the outer frame and the inner frame. This type of structure is cumbersome to install and disassemble, requiring the use of special tools such as screwdrivers and wrenches. This not only increases the labor cost of the initial assembly of the equipment, but also brings great inconvenience to the maintenance, cleaning or replacement of the air outlet blades in the later stage, seriously affecting the operating efficiency.
[0004] Therefore, an integrated air outlet blade fixing frame structure was designed. Utility Model Content
[0005] This utility model addresses the shortcomings of existing technologies by providing an integrated air outlet blade fixing frame structure. This solves the problem that most air outlet blade fixing frames on the market are split or connected by bolts and screws, requiring tools such as screwdrivers and wrenches for installation and disassembly. This increases the initial assembly time and cost of the equipment and makes it inconvenient for later blade maintenance, cleaning or replacement, seriously affecting operational efficiency.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: An integrated air outlet blade fixing frame structure includes an outer frame and an inner mounting frame. The inner mounting frame has snap-fit components on both sides. The outer frame and the inner mounting frame are snapped together by the snap-fit components. The outer frame is used to adapt and connect with the air outlet frame of an external device, and the inner mounting frame is used to install and fix the air outlet blades.
[0007] Preferably, each side of the outer frame is provided with a mounting groove, which extends along the height of the outer frame. Limiting blocks are fixedly installed on the inner walls of both sides of the outer frame, and the limiting blocks are located below the mounting groove and perpendicular to the inner wall of the outer frame.
[0008] Preferably, the inner wall of the outer frame is adapted to the outer wall of the mounting inner frame, and both have a rectangular cross-sectional shape. When the mounting inner frame is snapped onto the inner wall of the outer frame by the snap-fit component, the outer wall of the mounting inner frame is in contact with two limiting blocks, and the limiting blocks axially limit the bottom of the mounting inner frame.
[0009] Preferably, the buckle component includes a stop plate fixedly installed on the outer wall of the mounting inner frame. The stop plate is designed in an inclined shape, and the angle between the stop plate and the outer wall of the mounting inner frame is an acute angle. The stop plate has elastic deformation capability.
[0010] Preferably, the abutment plate and the mounting inner frame are integrally molded and made of the same plastic material. The free end of the abutment plate abuts against the mounting groove, and in the abutment state, the outer wall of the abutment plate is completely fitted with the inner wall of the mounting groove.
[0011] Preferably, the buckle component further includes a second mounting groove formed on the outer wall of the mounting inner frame. The second mounting groove is located inside the abutment plate, and a slider is slidably mounted inside the second mounting groove. The slider is hinged to the abutment plate, and the sliding direction of the slider is adapted to the tilting direction of the abutment plate.
[0012] Preferably, limiting strips are fixedly installed on the inner walls of both sides of the second mounting groove. The limiting strips extend along the length of the second mounting groove. Grooves are respectively provided on the outer walls of both sides of the slider. The grooves are adapted to and slidably connected with the limiting strips. The height of the limiting strips is equal to the depth of the grooves.
[0013] Preferably, the bottom of the second mounting groove and the limiting strip are both arc-shaped, the arc curvature of the bottom of the second mounting groove is consistent with the arc curvature of the limiting strip, and the bottom shape of the slider is adapted to the bottom shape of the second mounting groove to ensure the smoothness of the slider when sliding.
[0014] Compared with the prior art, the present invention has the following beneficial effects: After installation, the snap-fit component is flush with the outer frame and the outer wall of the inner frame, effectively preventing scratches. During installation, simply align the inner frame precisely with the inner wall of the outer frame, ensuring the snap-fit component corresponds to the first mounting groove, and press firmly. The process is quick and easy, requiring no complex tools or tedious operations. For disassembly, push the slider to deform the abutment plate, releasing the snap-fit and allowing separation. This convenient installation and disassembly method saves time, improves work efficiency, and is beneficial for initial equipment installation and subsequent maintenance and blade replacement. In terms of structural design, the outer frame and the inner frame are fitted with a rectangular cross-section, and a limiting block provides axial restraint at the bottom of the inner frame, enhancing stability. The snap-fit component's abutment plate is inclined and elastic, generating significant friction and clamping force to maintain a stable clamping state. The limiting strip in the second mounting groove matches the slider groove, ensuring stable slider sliding and effectively preventing offset and jamming. Attached Figure Description

[0021] It is understood that the term "a" should be understood as "at least one" or "one or more," that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.
[0022] Example 1: Please see Figure 1-6 An integrated air outlet blade fixing frame structure includes an outer frame 1 and an inner mounting frame 2. The inner mounting frame 2 has snap-fit components 3 on both sides. The outer frame 1 and the inner mounting frame 2 are snapped together by the snap-fit components 3. The outer frame 1 is used to adapt and connect with the air outlet frame of external equipment, and the inner mounting frame 2 is used to install and fix the air outlet blades.
[0023] The outer frame 1 has mounting grooves 11 on both sides, which extend along the height of the outer frame 1. Limiting blocks 12 are fixedly installed on the inner walls of both sides of the outer frame 1. The limiting blocks 12 are located below the mounting grooves 11 and are perpendicular to the inner walls of the outer frame 1.
[0024] The inner wall of the outer frame 1 is adapted to the outer wall of the inner frame 2. Both of them have a rectangular cross-sectional shape. When the inner frame 2 is snapped onto the inner wall of the outer frame 1 by the snap-fit component 3, the outer wall of the inner frame 2 is in contact with the two limiting blocks 12. The limiting blocks 12 form an axial limit on the bottom of the inner frame 2.
[0025] The buckle component 3 includes a stop plate 32 fixedly installed on the outer wall of the mounting inner frame 2. The stop plate 32 is designed in an inclined shape, and the angle between the stop plate 32 and the outer wall of the mounting inner frame 2 is an acute angle. The stop plate 32 has elastic deformation capability.
[0026] The abutment plate 32 and the mounting inner frame 2 are integrally molded and made of the same plastic material. The free end of the abutment plate 32 abuts against the mounting groove 11. In the abutting state, the outer wall of the abutment plate 32 is completely fitted with the inner wall of the mounting groove 11.
[0027] The snap-fit component 3 also includes a second mounting groove 30 formed on the outer wall of the inner mounting frame 2. The second mounting groove 30 is located inside the abutment plate 32. A slider 31 is slidably mounted inside the second mounting groove 30. The slider 31 is hinged to the abutment plate 32. The sliding direction of the slider 31 is adapted to the tilting direction of the abutment plate 32.
[0028] Limiting strips 301 are fixedly installed on the inner walls of both sides of the mounting groove 30. The limiting strips 301 extend along the length of the mounting groove 30. Grooves 311 are respectively opened on the outer walls of both sides of the slider 31. The grooves 311 are adapted to and slidably connected with the limiting strips 301. The height of the limiting strips 301 is equal to the depth of the grooves 311.
[0029] The bottom of the mounting groove 30 and the limiting strip 301 are both arc-shaped. The arc curvature of the bottom of the mounting groove 30 is consistent with the arc curvature of the limiting strip 301. The bottom shape of the slider 31 is adapted to the bottom shape of the mounting groove 30 to ensure the smoothness of the slider 31 when sliding.
[0030] During installation, first remove the inner frame 2 and align it precisely with the inner wall of the outer frame 1, ensuring that the snap-fit components 3 on both sides of the inner frame 2 correspond to the mounting grooves 11 on both sides of the outer frame 1. Then, press the inner frame 2 firmly and smoothly along the axial direction of the outer frame 1. During this process, the two inclined abutments 32 on the outer wall of the inner frame 2 will undergo elastic deformation due to the pressure from the inner wall of the outer frame 1, gradually sliding towards the corresponding mounting grooves 11 and finally abutting tightly against the inner wall of the mounting grooves 11. Continue pressing until the bottom of the inner frame 2 is completely fitted with the limiting block 12 on the inner wall of the outer frame 1. At this point, the inner frame 2 can no longer penetrate deeper into the outer frame 1, indicating that the correct installation position has been reached. The abutments 32 and the mounting grooves 11 abut against each other, thus fixing the inner frame 2 to the outer frame 1, and the installation process is complete.
[0031] During disassembly, use your fingers or a suitable simple component to push the slider 31 within the mounting groove 30 on the outer wall of the inner frame 2. Guided by the limiting strips 301 on both sides of the inner wall of the mounting groove 30 and the grooves 311 on both sides of the slider 31, the slider 31 will slide smoothly along the arc-shaped bottom of the mounting groove 30. This will cause the abutment 32, which is hinged to it, to undergo elastic deformation, gradually disengaging its free end from the abutment against the inner wall of the mounting groove 11, thus releasing the clamping fixation. After the abutment 32 has completely disengaged from the mounting groove 11, simply pull the inner frame 2 outwards to completely separate it from the outer frame 1, completing the disassembly.
[0032] After installation, the buckle component 3 is flush with the outer wall of the outer frame 1 and the inner frame 2. The flat outer wall can effectively avoid the scratching problem that may be caused by the buckle component 3 protruding. During installation, simply align the inner frame 2 precisely with the inner wall of the outer frame 1, ensuring that the snap-fit parts 3 on both sides correspond to the mounting grooves 11 on both sides of the outer frame 1. Then, press the inner frame 2 firmly and smoothly along the axial direction of the outer frame 1. During this process, the inclined abutment 32 on the outer wall of the inner frame 2 will undergo elastic deformation due to the pressure from the inner wall of the outer frame 1, gradually sliding towards the corresponding mounting groove 11 and finally abutting tightly against the inner wall of the mounting groove 11. Continue pressing until the bottom of the inner frame 2 is completely fitted with the limiting block 12 on the inner wall of the outer frame 1, indicating that the correct installation position has been reached. The entire installation process is easy and quick, requiring no complicated tools or tedious operating steps. When disassembly is required, simply push the slider 31 in the mounting groove 2 30 on the outer wall of the inner frame 2 with your fingers or a suitable simple component. Under the matching guidance of the limiting strips 301 on both sides of the inner wall of the mounting groove 2 30 and the grooves 311 on both sides of the slider 31, the slider 31 will slide smoothly along the arc-shaped bottom of the mounting groove 2 30, thereby causing the abutment plate 32 hinged to it to undergo elastic deformation, so that the free end of the abutment plate 32 gradually separates from the abutment state with the inner wall of the mounting groove 11, releasing the clamping fixation between the two. After the abutment plate 32 is completely separated from the mounting groove 11, simply pull the inner frame 2 outward to completely separate it from the outer frame 1. This convenient installation and disassembly method can greatly save time and effort and improve work efficiency, whether for the initial installation of the equipment or for later maintenance, replacement of air outlet blades, etc. The inner wall of the outer frame 1 is adapted to the outer wall of the inner frame 2, and both of them have rectangular cross-sectional shapes. This design provides a basis for the stable installation of the inner frame 2 inside the outer frame 1. When the inner frame 2 is snapped onto the inner wall of the outer frame 1 by the snap-fit component 3, the outer wall of the inner frame 2 is in contact with the two limiting blocks 12. The limiting blocks 12 form an axial limit on the bottom of the inner frame 2, which effectively prevents the inner frame 2 from moving axially inside the outer frame 1. Meanwhile, the design of the buckle component 3 further enhances the stability of the structure. The inclined design of the abutment plate 32 and the acute angle between it and the outer wall of the inner frame 2 allow the abutment plate 32 to generate greater friction and clamping force when it comes into contact with the mounting groove 11, ensuring that the inner frame 2 will not easily fall off the outer frame 1. Moreover, the abutment plate 32 has elastic deformation capability, which can deform to a certain extent when subjected to external force, and can return to its original shape when the external force disappears, thereby maintaining a stable clamping state. Limiting strips 301 are fixedly installed on the inner walls of both sides of the mounting groove 30. The limiting strips 301 extend along the length of the mounting groove 30. Grooves 311 that are adapted to and slidably connected to the limiting strips 301 are respectively opened on the outer walls of both sides of the slider 31. The height of the limiting strips 301 is equal to the depth of the grooves 311. This design ensures the stability of the slider 31 when sliding in the mounting groove 30, effectively avoiding the slider 31 from deviating or getting stuck during the sliding process. This allows the slider 31 to be pushed more smoothly during disassembly, causing the abutment plate 32 to undergo elastic deformation, thus achieving quick disassembly. In addition, the bottom of the mounting groove 2 30 and the limiting strip 301 are both arc-shaped, and the arc curvature of the bottom of the mounting groove 2 30 is consistent with the arc curvature of the limiting strip 301. The bottom shape of the slider 31 is adapted to the bottom shape of the mounting groove 2 30. The arc design further improves the smoothness of the slider 31 when sliding, making the operation easier and less strenuous.
[0033] like Figure 4 and Figure 5 As shown, the side of the mounting groove 11 that contacts the abutment 32 is bent inward, so that when the abutment 32 comes into contact with the mounting groove 11, the inward bending part can limit the abutment 32, effectively preventing the abutment 32 from detaching from the mounting groove due to vibration or other factors.
[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
