[0007] A locking component, comprising an elastic element and a movable element, wherein one end of the elastic element is connected to the first mesh cover and the other end is connected to the movable element;

[0008] The elastic element has a compressed state and a natural state. The movable element can compress the elastic element under the action of an external force so that the elastic element is in the compressed state. In the compressed state, the second mesh cover can rotate relative to the first mesh cover so that the protrusion enters or leaves the receiving groove.

[0009] When the elastic element is in its natural state, the movable element can restrict the rotation of the second mesh cover.

[0010] Furthermore, the movable part is located at the entrance of the receiving slot, and the movable part can close or open the entrance of the receiving slot under the action of external force.

[0011] Furthermore, the protrusion can abut against the movable member to open the entrance of the receiving slot.

[0012] Furthermore, the first mesh cover is provided with a connecting groove, and the movable part is provided with a slot, the slot being exposed to the outside through the connecting groove.

[0013] Furthermore, the first mesh cover is provided with a connecting groove, and the movable part is provided with a lever portion, which is exposed to the outside through the connecting groove.

[0014] Furthermore, the second mesh cover is provided with positioning holes, and controlling the movement of the paddle part can drive the movable part into or out of the positioning holes.

[0015] Furthermore, the locking assembly also includes a mounting base connected to the first mesh cover, one end of the elastic member being connected to the mounting base and the other end being connected to the movable member.

[0016] Furthermore, the mounting base is provided with a limiting groove, and the movable part is provided with a limiting block. The limiting block is located in the limiting groove, and the limiting block can move along the limiting groove.

[0036] Existing fan grilles generally include a detachable front grille and a rear grille. After the front and rear grilles are fixed in place, they are typically secured with screws or clips to prevent loosening. However, these methods are inconvenient when the front grille needs to be removed for cleaning, as screws may be lost or clips may be accidentally broken during disassembly, making it difficult to re-secure the front grille. This application addresses these problems by providing a fan grille that solves the inconvenience of assembling and disassembling existing fan grilles.

[0037] In some embodiments, such as Figures 1-10 As shown, a fan guard is provided, comprising:

[0038] A first mesh cover 1, the first mesh cover 1 being provided with a receiving groove 11;

[0039] The second mesh cover 2 is connected to the first mesh cover 1 and the second mesh cover 2, and the second mesh cover 2 is provided with a protrusion 21;

[0040] Locking component 3, the locking component 3 includes an elastic element 31 and a movable element 32, one end of the elastic element 31 is connected to the first mesh cover 1, and the other end is connected to the movable element 32;

[0041] The elastic element 31 has a compressed state and a natural state. The movable element 32 can compress the elastic element 31 under the action of external force so that the elastic element 31 is in the compressed state. In the compressed state, the second mesh cover 2 can rotate relative to the first mesh cover 1 so that the protrusion 21 enters or leaves the receiving groove 11.

[0042] When the elastic member 31 is in the natural state, the movable member 32 can restrict the rotation of the second mesh cover 2.

[0043] The fan guard of this application connects the first guard 1 and the second guard 2 through the cooperation of the protrusion 21 with the receiving groove 11, restricting the displacement of the first guard 1 and the second guard 2 in the front-back direction; the second guard 2 can be controlled to move or lock through the elastic member 31 and the movable member 32. When an external force is applied to the movable member 32 to compress the elastic member 31, the second guard 2 can rotate freely, allowing the protrusion 21 to enter or leave the receiving groove 11. When the protrusion 21 leaves the receiving groove 11, the first guard 1 and the second guard 2 can be separated; when the protrusion 21 enters... After the first mesh cover 1 is inserted into the receiving groove 11, the external force applied to the movable part 32 is stopped, and the elastic part 31 returns to its natural state, so that the movable part 32 restricts the rotation of the second mesh cover 2. At this point, the installation of the first mesh cover 1 and the second mesh cover 2 is completed. When it is necessary to separate the first mesh cover 1 and the second mesh cover 2, the external force is applied to the movable part 32 to release the lock on the second mesh cover 2. The second mesh cover 2 rotates so that the protrusion 21 disengages from the receiving groove 11, thereby separating the second mesh cover 2 from the first mesh cover 1. The disassembly process of the first mesh cover 1 and the second mesh cover 2 does not require the use of screws or clips, which is simple and convenient and improves the efficiency of disassembly and assembly.

[0044] In some embodiments, such as Figure 9 and Figure 10 As shown, the movable part 32 is located at the entrance of the receiving slot 11, and the movable part 32 can close or open the entrance of the receiving slot 11 under the action of external force.

[0045] The movable part 32 is located at the entrance of the receiving groove 11. When no external force is applied to the movable part 32, it blocks the entrance of the receiving groove 11, preventing the protrusion 21 from entering. When an external force is applied to the movable part 32, the elastic member 31 is compressed from its natural state to a compressed state, and the movement of the movable part 32 opens the entrance of the receiving groove 11. At this time, rotating the second mesh cover 2 allows the protrusion 21 to enter the receiving groove 11. After the protrusion 21 enters the receiving groove 11, the application of external force to the movable part 32 is stopped. The elastic element 31 returns from the compressed state to its natural state, causing the movable element 32 to reset and close the entrance of the receiving groove 11, preventing the protrusion 21 from leaving the receiving groove 11, which is equivalent to restricting the movement of the second mesh cover 2. By setting the movable element 32 at the entrance of the receiving groove 11, the movable element 32 can not only restrict the movement of the protrusion 21 to limit the displacement of the first mesh cover 1 and the second mesh cover 2 in the front-back direction, but also restrict the rotation of the second mesh cover 2, simplifying the assembly and disassembly of the first mesh cover 1 and the second mesh cover 2.

[0046] In some embodiments, such as Figure 9 and Figure 10As shown, the protrusion 21 abuts against the movable member 32, allowing the movable member 32 to open the entrance of the receiving groove 11. When the second mesh cover 2 is assembled with the first mesh cover 1, the protrusion 21 abuts against the movable member 32, applying a force to the movable member 32, causing the movable member 32 to move and open the entrance of the receiving groove 11. At this time, rotating the second mesh cover 2 allows the protrusion 21 to enter the receiving groove 11. After the protrusion 21 enters the receiving groove 11, the elastic member 31 returns to its natural state, driving the movable member 32 to reset, continuing to close the entrance of the receiving groove 11 and restricting the rotation of the second mesh cover 2. By providing external force through the protrusion 21 abutting against the movable member 32, the opening or closing of the receiving groove 11 can be completed during the assembly process of the second mesh cover 2 and the first mesh cover 1, simplifying the assembly process.

[0047] In some embodiments, such as Figures 4-8 As shown, the first mesh cover 1 is provided with a connecting groove 12, and the movable part 32 is provided with a slot 321, which is exposed to the outside through the connecting groove 12.

[0048] By setting the slot 321 and the connecting groove 12, the user can insert the tool into the slot 321 through the connecting groove 12, and then apply force to the movable part 32 through the tool to make the movable part 32 move. This operation method can prevent children from accidentally disassembling the first mesh cover 1 and the second mesh cover 2, ensuring safe use.

[0049] In some embodiments, the slot 321 of the movable part 32 is square, and the user can insert a flathead screwdriver into the slot 321 to control the movement of the movable part 32.

[0050] In some embodiments, such as Figure 11 and Figure 12 As shown, the first mesh cover 1 has a communicating groove 12, and the movable member 32 has a lever portion 322, which is exposed to the outside through the communicating groove 12. By setting the lever portion 322, the user can control the movement of the movable member by manipulating the lever portion 322 without the need for tools, making the operation simple and convenient.

[0051] In some embodiments, the second mesh cover 2 is provided with a positioning hole (not shown). Controlling the movement of the paddle part 322 can drive the movable member 32 into or out of the positioning hole. When the movable member 32 enters the positioning hole, the movable member 32 restricts the rotation of the second mesh cover 2. After operating the paddle part 322 to disengage the movable member 32 from the positioning hole, the second mesh cover 2 can rotate. In this way, the user can determine whether the first mesh cover 1 and the second mesh cover 2 are properly assembled by observing whether the movable member 32 is located in the positioning hole.

[0052] In some embodiments, such as Figures 4-8As shown, the locking assembly 3 also includes a mounting base 33, which is connected to the first mesh cover 1. One end of the elastic member 31 is connected to the mounting base 33, and the other end is connected to the movable member 32. By connecting the mounting base 33 to the first mesh cover 1, the installation of the movable member 32 and the elastic member 31 is facilitated.

[0053] In some embodiments, the elastic element 31 is a spring, the mounting base 33 and the movable element 32 are respectively provided with a sleeve shaft, and the two ends of the spring are respectively sleeved on the sleeve shaft of the mounting base 33 and the movable element 32. The mounting base 33 is fixed to the first mesh cover 1 by screws. The structure is simple and the installation is convenient.

[0054] In some embodiments, such as Figures 4-8 As shown, the mounting base 33 is provided with a limiting groove 331, and the movable component 32 is provided with a limiting block 323. The limiting block 323 is located within the limiting groove 331 and can move along the limiting groove 331. By setting the limiting groove 331 and the limiting block 323, the movement trajectory of the movable component 32 is limited, preventing the movable component 32 from tilting and ensuring that the locking component 3 remains effective.

[0055] In some embodiments, such as Figures 4-10 As shown, the first mesh cover 1 is provided with a guide part 13, which is used to guide the protrusion 21 to move to the entrance of the receiving groove 11. By providing the guide part 13, when the second mesh cover 2 is assembled with the first mesh cover 1, the guide part 13 can guide the protrusion 21 to move to the receiving groove 11, thereby improving assembly efficiency and assembly accuracy.

[0056] In some embodiments, the guide portion 13 is an inclined guide plate that is inclined toward the entrance of the receiving groove 11.

[0057] In some embodiments, the first mesh cover 1 is provided with a locking mark and an unlocking mark, and the second mesh cover 2 is provided with an indicator mark that can be aligned with the locking mark or the unlocking mark.

[0058] When the second mesh cover 2 is assembled with the first mesh cover 1, first align the indicator mark with the unlock mark. At this time, the second mesh cover 2 can rotate, causing the protrusion 21 to enter the receiving groove 11. After the protrusion 21 is fully in the receiving groove 11, the indicator mark aligns with the locking mark. At this time, the movable part 32 restricts the rotation of the second mesh cover 2, completing the assembly of the second mesh cover 2 and the first mesh cover 1. When the second mesh cover 2 is separated from the first mesh cover 1, apply an external force to the movable part 32 to move the movable part 32 and release the rotation restriction on the second mesh cover 2. At this time, rotate the second mesh cover 2. When the indicator mark aligns with the unlock mark, the second mesh cover 2 and the first mesh cover 1 can be disassembled and separated. By setting the indicator mark, locking mark and unlock mark, it is convenient for the user to know the connection status of the first mesh cover 1 and the second mesh cover 2.

[0059] It should be noted that while the preferred embodiments of this utility model are provided in the specification and accompanying drawings, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are not intended to impose additional limitations on the content of this utility model; their purpose is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Furthermore, the above-described technical features can be combined with each other to form various embodiments not listed above, all of which are considered to be within the scope of this utility model specification.
