[0011] In a preferred embodiment of this invention, the fastener includes an extended buckle, which is disposed on the mounting ring; the extended buckle is disposed near the fixing groove to fix the mounting portion of the exhaust pipe within the fixing groove.

[0012] In a preferred embodiment of this invention, a reinforcing rib is connected to the side of the outer extension buckle away from the fixing groove. The reinforcing rib is used to increase the fixing effect of the outer extension buckle on the exhaust pipe.

[0013] In a preferred embodiment of this invention, the outer circumferential side of the mounting ring is provided with a plurality of assembly notches, which are used to provide the force points required to grip the grille body.

[0014] An outer cover includes an outer cover body, the outer cover body having an assembly opening, an annular protrusion being provided inside the assembly opening, the annular protrusion having M first snap-fit ​​holes and N second snap-fit ​​holes circumferentially arranged, the first snap-fit ​​holes being adapted to the rotating snap-fit ​​of the grille, and the second snap-fit ​​holes being adapted to the anti-reverse snap-fit ​​of the grille.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model provides a grille, including a grille body. M rotating buckles and N anti-reverse buckles are circumferentially arranged on the first side of the grille body. The rotating buckles guide the forward rotation of the grille body, and the anti-reverse buckles restrict the reverse rotation of the grille body. A fixing member is provided on the second side of the grille body for fixing an external exhaust pipe. Wherein, M ≥ 1, N ≥ 1. Forward rotation is exemplified by clockwise rotation, and reverse rotation by counterclockwise rotation. The grille body is elastic and capable of elastic deformation. The first side of the grille body is provided with rotating buckles and anti-reverse buckles; one or more rotating buckles and one or more anti-reverse buckles can be provided. During grille installation, the rotating clips guide the grille body's forward rotation. As the grille body rotates clockwise, the rotating clips turn towards their predetermined positions. Simultaneously, the anti-reverse clips, under pressure, cause the grille body to elastically deform. Once the grille body is fully rotated, both the rotating clips and the anti-reverse clips reach their predetermined positions, at which point the grille body returns to its original shape. After the anti-reverse clips reach their predetermined positions, they resist the grille body's reverse rotation, preventing it from rotating counter-clockwise once installed, thus effectively securing the grille body. Without affecting the grille body's appearance and performance, a fixing component is added to the second side of the grille body. This addition not only facilitates the installation of the exhaust duct but also enhances the duct's fixation. Attached Figure Description

[0027] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0028] Example 1

[0029] like Figures 1-7 As shown, this embodiment provides a grille, including a grille body 1. The first side of the grille body 1 is circumferentially provided with M rotating buckles 2 and N anti-reverse buckles 3. The rotating buckles 2 are used to guide the forward rotation of the grille body 1, and the anti-reverse buckles 3 are used to restrict the reverse rotation of the grille body 1. The second side of the grille body 1 is provided with a fixing member, which is used to fix an external exhaust pipe. Wherein, M≥1, N≥1.

[0030] The rotating latch 2 features a chamfered design. The chamfer provides guidance for the insertion and assembly of the rotating latch 2, reducing alignment difficulties during assembly and making it easier for the rotating latch 2 to reach the intended position, thereby improving assembly efficiency. One or more rotating latches 2 can be provided; this is not limited here.

[0031] The anti-reverse clip 3 is inverted triangular in shape, providing better anti-reverse effect under force. The pointed end of the anti-reverse clip 3 can better embed into the predetermined position, thereby effectively preventing the grille body 1 from rotating in the opposite direction or loosening during installation. One or more anti-reverse clips 3 can be provided, which is not limited here.

[0032] The grating body 1 is an injection-molded part, possessing elasticity and capable of elastic deformation. Preferably, the grating body 1 has a disc-shaped structure, making it easier to rotate. The grating body 1 can rotate clockwise or counterclockwise. This embodiment uses clockwise rotation as an example and counterclockwise rotation as a reference. When installing the grating body 1, it is first placed in the assembly position, and then rotated clockwise. During rotation, the rotating latch 2 guides the rotation of the grating body 1, causing it to rotate in the predetermined direction. Simultaneously, the anti-reverse latch 3, under pressure, causes the grating body 1 to undergo elastic deformation until it reaches its predetermined position. Once the grating body 1 reaches its predetermined position, both the anti-reverse latch 3 and the rotating latch 2 reach their predetermined positions. When the anti-reverse latch 3 reaches its predetermined position, it generates counterclockwise resistance against the grating body 1, preventing it from rotating counterclockwise and thus fixing the grating body 1 in the installation position, effectively securing it.

[0033] The design incorporates fasteners that allow the exhaust duct to be directly mounted on the grille body 1, thereby assisting the outdoor unit in exhausting air or utilizing wind power within confined spaces. Adding fasteners not only strengthens the installation of the exhaust duct but also does not compromise the structural strength and performance of the grille body 1.

[0034] This embodiment provides a grille, including a grille body 1. M rotating latches 2 and N anti-reverse latches 3 are circumferentially arranged on the first side of the grille body 1. The rotating latches 2 guide the forward rotation of the grille body 1, and the anti-reverse latches 3 restrict the reverse rotation of the grille body 1. A fixing member is provided on the second side of the grille body 1 for fixing an external exhaust pipe; wherein M≥1 and N≥1. In this embodiment, forward rotation is exemplified by clockwise rotation, and reverse rotation by counterclockwise rotation. The grille body 1 is elastic and capable of elastic deformation. The first side of the grille body 1 is provided with rotating latches 2 and anti-reverse latches 3. One or more rotating latches 2 and one or more anti-reverse latches 3 can be provided. During the installation of the grille, the rotating clip 2 guides the forward rotation of the grille body 1. When the grille body 1 rotates forward, for example clockwise, the rotating clip 2 rotates towards the predetermined position. Simultaneously, the anti-reverse clip 3, under pressure, causes the grille body 1 to undergo elastic deformation until it reaches its correct position. At this point, both the rotating clip 2 and the anti-reverse clip 3 reach their predetermined positions, and the grille body 1 returns to its original deformation. After the anti-reverse clip 3 reaches its predetermined position, it resists the reverse rotation of the grille body 1, i.e., it resists the counter-clockwise rotation of the grille body 1, preventing it from rotating counter-clockwise after installation, thus effectively fixing the grille body 1. Without affecting the appearance and performance of the grille body 1, a fixing component is added to the second side of the grille body 1. This addition not only facilitates the installation of the exhaust duct but also enhances the fixing effect of the exhaust duct.

[0035] Example 2

[0036] like Figures 1-7 As shown, this embodiment provides a grille, including a grille body 1. The first side of the grille body 1 is circumferentially provided with M rotating buckles 2 and N anti-reverse buckles 3. The rotating buckles 2 are used to guide the forward rotation of the grille body 1, and the anti-reverse buckles 3 are used to restrict the reverse rotation of the grille body 1. The second side of the grille body 1 is provided with a fixing member, which is used to fix an external exhaust pipe. Wherein, M≥1, N≥1.

[0037] The grille body 1 has a disc-shaped structure and includes a mounting ring 4. M rotating buckles 2 are arranged circumferentially on the inner ring side of the mounting ring 4, and the rotating buckles 2 extend circumferentially along the grille body 1.

[0038] M≥2, M of the rotating buckles 2 are spaced apart, and a backstop buckle 3 is provided between adjacent rotating buckles 2.

[0039] The grille body 1 includes multiple spokes 5 and multiple annular structures 6, which are staggered and located on the inner ring side of the mounting ring 4.

[0040] The grille body 1 is disc-shaped, giving it excellent symmetry and stability, making it easier to rotate and install in the installation space, and allowing for good compatibility with exhaust ducts. The mounting ring 4 is located on the outer edge of the grille body 1, while multiple spokes 5 and multiple annular structures 6 are located on the inner edge of the mounting ring 4. The staggered spokes 5 and annular structures 6 form a stable and efficient mechanical support system. The spokes 5 extend radially along the grille body 1, and the annular structures 6 extend circumferentially. This staggered structure not only distributes stress but also improves the overall strength and stability of the grille, giving it good resistance to deformation under external forces. Simultaneously, this staggered structure provides symmetry and aesthetics, increasing visual width and layering, achieving a unity of high strength, high stability, and high aesthetics in the grille body 1.

[0041] This embodiment uses an example where six rotating clips 2 are circumferentially arranged on the inner ring side of the mounting ring 4. The six rotating clips 2 are evenly distributed circumferentially on the inner ring side of the mounting ring 4, which not only gives the grille body 1 a certain aesthetic appeal but also ensures that the grille body 1 receives uniform fixing force in all directions after installation, avoiding damage or loosening caused by single-point force. The six rotating clips 2 effectively disperse the force on the grille body 1, improving its stability and reliability.

[0042] This embodiment uses an example where a check buckle 3 is provided between two adjacent rotating buckles 2. The check buckle 3 is provided to prevent the grille body 1 from rotating in the reverse direction during installation or use, thereby ensuring that the grille body 1 remains in the correct position after installation, achieving effective fixation of the grille body 1. For example, in a ventilation system, the impact of airflow may generate a certain rotational force on the grille body 1, and the check buckle 3 can prevent this rotation, ensuring that the grille body 1 always remains in a fixed position. By providing one check buckle 3, the product structure design can be simplified, manufacturing costs can be reduced, and the assembly difficulty of the grille body 1 can be reduced.

[0043] The outer circumferential side of the mounting ring 4 is provided with a plurality of assembly notches 10, which are used to provide the force points required to grip the grille body 1.

[0044] The assembly notch 10 provides a gripping point for the grille installation process, allowing operators to more easily grasp and rotate the grille body 1, thus enabling rapid assembly. The design of the assembly notch 10 reduces reliance on assembly tools and improves assembly efficiency.

[0045] The grille body 1 in this embodiment has a disc-shaped structure. The grille body 1 includes a mounting ring 4. M rotating buckles 2 are circumferentially arranged on the inner ring side of the mounting ring 4, extending circumferentially along the grille body 1. M ≥ 2, and the M rotating buckles 2 are spaced apart. A backstop buckle 3 is provided between adjacent rotating buckles 2. The grille body 1 includes multiple spokes 5 and multiple annular structures 6, which are staggered and located on the inner ring side of the mounting ring 4. Several assembly notches 10 are circumferentially arranged on the outer ring side of the mounting ring 4. These notches provide the necessary force points for gripping the grille body 1. Six rotating buckles 2 are circumferentially arranged on the inner ring side of the mounting ring 4. These six rotating buckles 2 not only provide guidance for the rotational installation of the grille body 1 but also ensure that the grille body 1 receives uniform fixing force in all directions after installation, avoiding damage or loosening due to single-point force. A check buckle 3 is provided between two adjacent rotating buckles 2. After the grille body 1 is installed in place by rotating it in the forward direction, the check buckle 3 can prevent the grille body 1 from rotating in the reverse direction. The check buckle 3 not only simplifies the structural design of the grille body 1 and reduces the assembly difficulty, but also enables the grille body 1 to be effectively fixed after installation.

[0046] Example 3

[0047] like Figures 1-7 As shown, this embodiment provides a grille, including a grille body 1. The first side of the grille body 1 is circumferentially provided with M rotating buckles 2 and N anti-reverse buckles 3. The rotating buckles 2 are used to guide the forward rotation of the grille body 1, and the anti-reverse buckles 3 are used to restrict the reverse rotation of the grille body 1. The second side of the grille body 1 is provided with a fixing member, which is used to fix an external exhaust pipe. Wherein, M≥1, N≥1.

[0048] The grille body 1 has a disc-shaped structure and includes a mounting ring 4. M rotating buckles 2 are arranged circumferentially on the inner ring side of the mounting ring 4, and the rotating buckles 2 extend circumferentially along the grille body 1.

[0049] The outer ring of the mounting ring 4 has a fixing groove 7, which is used to install the exhaust pipe.

[0050] The fixing groove 7 is formed on the outer side of the mounting ring 4. The fixing groove 7 extends both radially and circumferentially along the mounting ring 4. The size of the fixing groove 7 is adapted to the outer diameter of the exhaust pipe, thus providing a precise and stable installation position for the exhaust pipe. After the exhaust pipe is embedded in the fixing groove 7, the fixing groove 7 can accurately position and initially fix the exhaust pipe, ensuring that it will not shift or shake during the installation process.

[0051] The fastener includes an extended buckle 8, which is disposed on the mounting ring 4; the extended buckle 8 is disposed near the fixing groove 7 to fix the mounting part of the exhaust pipe in the fixing groove 7.

[0052] When the exhaust pipe is placed in the fixing groove 7, the outer buckle 8 can fit tightly against the outer wall of the exhaust pipe, apply a certain pressure to the outer wall of the exhaust pipe, thereby firmly fixing the exhaust pipe in the fixing groove 7 and preventing the exhaust pipe from loosening or falling off due to vibration or other external forces during operation.

[0053] The outer extension buckle 8 is connected to a reinforcing rib 9 on the side away from the fixing groove 7. The reinforcing rib 9 is used to support the outer extension buckle 8, so that the outer extension buckle 8 can better fix the exhaust pipe.

[0054] The reinforcing rib 9 provides additional support for the extended clip 8, making it more stable when fixing the exhaust pipe and preventing the exhaust pipe from vibrating or falling off due to loosening of the extended clip 8. When the extended clip 8 fixes the exhaust pipe in the fixing groove 7 of the mounting ring 4, the exhaust pipe may be subjected to forces from different directions during operation, such as vibration, airflow impact, or accidental collisions during installation. These forces may adversely affect the fixing effect of the extended clip 8. By connecting the reinforcing rib 9 to the outside of the clip, the deformation resistance of the extended clip 8 can be significantly enhanced, and the service life of the extended clip 8 can be extended.

[0055] In this embodiment, the outer ring of the mounting ring 4 has a fixing groove 7 for installing the exhaust pipe. The fixing member includes an extended clip 8, which is disposed on the mounting ring 4. The extended clip 8 is positioned close to the fixing groove 7 to secure the installation portion of the exhaust pipe within the fixing groove 7. A reinforcing rib 9 is connected to the side of the mounting ring 4 away from the fixing groove 7. The reinforcing rib 9 supports the extended clip 8, allowing it to better secure the exhaust pipe. The shape of the fixing groove 7 is adapted to the exhaust pipe, and the size of the fixing groove 7 is less than or equal to the outer diameter of the exhaust pipe. If the exhaust pipe is made of a deformable material, the size of the fixing groove 7 is smaller than the outer diameter of the exhaust pipe, creating an interference fit between the exhaust pipe and the fixing groove 7. This allows the exhaust pipe to be securely installed within the fixing groove 7, achieving initial positioning of the exhaust pipe. Once the exhaust duct is installed in the fixing groove 7, the extended clip 8 can stably fix the exhaust duct in the fixing groove 7, preventing the exhaust duct from loosening or falling off due to vibration or other external forces during operation. At the same time, the reinforcing rib 9 provides additional support for the extended clip 8, making the extended clip 8 more stable when fixing the exhaust duct.

[0056] Example 4

[0057] like Figures 1-7 As shown, this embodiment provides an outer cover, including an outer cover body 11. The outer cover body 11 has an assembly opening 12. An annular protrusion 13 is provided in the assembly opening 12. The annular protrusion 13 has M first snap-fit ​​holes 14 and N second snap-fit ​​holes 15 circumferentially arranged. The first snap-fit ​​holes 14 are adapted to the rotating snap-fit ​​2 of the grille in Embodiment 1, Embodiment 2 or Embodiment 3. The second snap-fit ​​holes 15 are adapted to the anti-reverse snap-fit ​​3 of the grille in Embodiment 1, Embodiment 2 or Embodiment 3.

[0058] The second buckle hole 15 includes a mounting groove 16 and a guide groove 17, the guide groove 17 being connected to the mounting groove 16; the guide groove 17 gradually decreases in size from one end near the mounting groove 16 to the other end away from the mounting groove 16, and a baffle 18 is provided in the mounting groove 16, the baffle 18 being used to increase the contact area of ​​the anti-reverse buckle 3.

[0059] The outer cover body 11 has an assembly opening 12, the size and shape of which are adapted to the mounting ring 4 of the grille body 1. An annular protrusion 13 is provided inside the assembly opening 12, and M first snap-fit ​​holes 14 are circumferentially arranged on the annular protrusion 13. In this embodiment, six first snap-fit ​​holes 14 are circumferentially arranged on the annular protrusion 13. The six snap-fit ​​holes are evenly distributed on the annular protrusion 13 and are aligned with the positions of the rotating snap-fit ​​2 of the grille body 1. The first snap-fit ​​hole 14 includes a head region and a tail region, with the head region being wider and the tail region narrower, and the head region and tail region being connected. The first snap-fit ​​hole 14 is adapted to the rotating snap-fit ​​2 of the grille body 1, facilitating the rotational installation of the grille. During the rotational installation of the grille, the rotating snap-fit ​​2 first enters the head region of the first snap-fit ​​hole 14. After the grille is rotated into position, the rotating snap-fit ​​2 engages with the tail region of the first snap-fit ​​hole 14, thus completing the installation of the grille. The dimensional change of the first buckle hole 14 from the head area to the tail area can reduce the resistance during assembly and prevent the rotating buckle 2 from getting stuck or damaged due to size mismatch.

[0060] The annular protrusion 13 is also provided with N second snap-fit ​​holes 15. In this embodiment, one second snap-fit ​​hole 15 is provided on the annular protrusion 13 as an example. The second snap-fit ​​hole 15 is located between two of the first snap-fit ​​holes 14. The second snap-fit ​​hole 15 is used to fit the anti-reverse snap 3 of the grille body 1, and plays a role in fixing the grille body 1 and preventing the grille body 1 from reversing. The second snap-fit ​​hole 15 includes a mounting groove 16 and a guide groove 17, and the guide groove 17 is connected to the mounting groove 16. The guide groove 17 gradually decreases in size from the end near the mounting groove 16 to the end away from the mounting groove 16. This structure of the guide groove 17 helps to guide the anti-reverse snap 3 smoothly into the mounting groove 16. A baffle 18 is provided in the mounting groove 16. The function of the baffle 18 is to increase the contact area of ​​the anti-reverse snap 3. The larger contact area provides stronger friction, further enhancing the anti-reverse effect of the anti-reverse snap 3, thereby improving the stability and reliability of the grille after installation.

[0061] An air conditioner outdoor unit 19 includes a grille as described in Embodiment 1, Embodiment 2 or Embodiment 3, and an outer cover.

[0062] The outdoor unit 19 is an important component of the air conditioning system, primarily responsible for the compression and condensation of refrigerant and the release of heat. The outer casing is the outer shell of the outdoor unit 19, mainly serving a protective and decorative function. The grille is a component installed inside or outside the casing, primarily used to protect the fan and condenser, and also has a decorative purpose. The grille is secured to the casing by rotating clips 2 and anti-reverse clips 3. Rotating clips 2 guide the grille to rotate forward during installation, while anti-reverse clips 3 prevent the grille from rotating backward after it is in place, thus ensuring the grille is stably fixed to the casing and preventing it from loosening or falling off under external force.

[0063] This embodiment provides an outer cover, including an outer cover body 11. The outer cover body 11 has an assembly opening 12, and an annular protrusion 13 is provided in the assembly opening 12. The annular protrusion 13 has M first snap-fit ​​holes 14 and N second snap-fit ​​holes 15 circumferentially arranged. The first snap-fit ​​holes 14 are adapted to the rotating snap-fit ​​2 of the grille in Embodiment 1, Embodiment 2, or Embodiment 3. The second snap-fit ​​holes 15 are adapted to the anti-reverse snap-fit ​​3 of the grille in Embodiment 1, Embodiment 2, or Embodiment 3. The second snap-fit ​​hole 15 includes a mounting groove 16 and a guide groove 17. The guide groove 17 communicates with the mounting groove 16. The guide groove 17 gradually decreases in size from one end near the mounting groove 16 to the end away from the mounting groove 16. A baffle 18 is provided in the mounting groove 16, and the baffle 18 is used to increase the contact area of ​​the anti-reverse snap-fit ​​3. An air conditioner outdoor unit 19 includes the grille in Embodiment 1, Embodiment 2, or Embodiment 3, and an outer cover. When the grille is rotated, the rotating buckle 2 first enters the head area of ​​the first buckle hole 14, and the anti-reverse buckle 3 presses against the contact surface of the outer cover, causing elastic deformation of both the grille body 1 and the contact surface of the outer cover in the area of ​​the anti-reverse buckle 3. Once the grille is rotated into position, the rotating buckle 2 fully enters the tail area of ​​the first buckle hole 14. Simultaneously, the anti-reverse buckle 3 enters the mounting groove 16 of the second buckle hole 15 along the guide groove 17. The contact surfaces of the grille body 1 and the outer cover then regain their elastic deformation, thus completing the assembly and fixation of the grille and the outer cover. The first buckle hole 14 is used to adapt to the rotating buckle 2 of the grille body 1, facilitating the rotational installation of the grille. The second buckle hole 15 adapts to the anti-reverse buckle 3 of the grille body 1, serving to fix the grille body 1 and prevent its reverse rotation. Through the cooperation of the rotating buckle 2 and the anti-reverse buckle 3, rapid assembly and secure fixation of the grille and the outer cover are achieved, significantly improving assembly efficiency.
