[0045] In the embodiment of the present application, the first connecting structure 2 comprises the connecting seat 21, the fixing piece 22 and the locking piece 23, wherein the connecting seat 21 is used for connecting with one of the front cover body 11 and the rear cover body 12, in the connecting state of the first connecting structure 2, the first connecting hole 22a of the fixing piece 22 is penetrated by the locking piece 23, and then the fixing piece 22 and the other one of the front cover body 11 and the rear cover body 12 are cooperatively locked, since the fixing seat is also detachably connected with the connecting seat 21, the cooperative installation between the front cover body 11 and the rear cover body 12 is realized, and the locking piece 23 can be detachably installed at the fixing piece 22 and the cover body 1, by installing and detaching the locking piece 23, the cooperation and detachment between the front cover body 11 and the rear cover body 12 can be further realized, the quick assembly and disassembly effect can be realized while the connection reliability is maintained, thereby effectively solving the inconvenient maintenance problem caused by the rotating shaft structure in the prior art, and the assembly efficiency of the mesh cover 100 and the convenience of the later maintenance are improved.

[0046] In the connecting state, the connecting seat 21 connects one of the front cover body 11 and the rear cover body 12, and the fixing piece 22 connects the other one of the front cover body 11 and the rear cover body 12, so that the connection between the front cover body 11 and the rear cover body 12 can be realized.

[0047] For example, in the connecting state, the connecting seat 21 connects the front cover body 11, and the fixing piece 22 connects the rear cover body 12; or, in the connecting state, the connecting seat 21 connects the rear cover body 12, and the fixing piece 22 connects the front cover body 11, both connection modes can be used, which is not limited in the present application.

[0048] In the embodiment of the present application, the front cover body 11 and the rear cover body 12 are cooperatively installed through the first connecting structure 2, the peripheries of the front cover body 11 and the rear cover body 12 are attached to each other to form the cover body 1, the cover body 1 is hollowly arranged, and the internal space is used for accommodating a fan blade and the like.

[0049] Specifically, since the connecting seat 21 and the fixing member 22 are provided in a split mode, and the fixing member 22 is connected with the locking member 23, the material of the fixing member 22 includes polycarbonate (PC) material, ABS material, etc., which is not limited in the present application, and the material of the fixing member 22 needs to have the characteristics of high hardness and high strength, so as to facilitate the cooperation and fixation with the locking member 23.

[0050] In the embodiment of the present application, the locking member 23 includes a threaded connecting member, such as a screw, a screw rod, etc., and also includes a bolt, a rivet, etc., which is not limited in the present application, and can achieve the fixing effect.

[0051] In addition, the fixing member 22 is used for cooperating with the locking member 23 for installation, and the repeated disassembly of the locking member 23 can cause wear of the fixing member 22. The connecting seat 21 and the fixing member 22 are provided in a detachable mode, and in the actual application process, the stability of the installation function of the locking member 23 can be achieved by replacing the fixing member 22, and the durability of the mesh cover 100 is further improved.

[0052] Further, please refer to Figures 3 to 10 The connecting seat 21 is provided with a mounting groove 212a, and in the connected state, part of the fixing member 22 passes through the opening of the mounting groove 212a and is placed in the mounting groove 212a, and the fixing member 22 is connected with the connecting seat 21 in a clamping manner. In some embodiments, the connecting seat 21 is provided with the mounting groove 212a, so that part of the fixing member 22 is placed in the mounting groove 212a and connected by clamping. On the one hand, the mounting groove 212a has a certain guiding effect, which can accurately position the relative position of the fixing member 22 and the connecting seat 21, and reduce the difficulty of alignment in the assembly process. On the other hand, the clamping connection of the fixing member 22 and the connecting seat 21 can reduce the sliding deviation during installation, improve the assembly stability, and further optimize the assembly efficiency and structural reliability.

[0053] In some embodiments, please refer to Figures 3 to 6 The mounting groove 212a extends along the extension direction of the first connecting hole 22a, and the first connecting hole 22a is located in the mounting groove 212a. The connecting seat 21 is also provided with a second connecting hole 212b which is in communication with the mounting groove 212a. In the connected state, the locking member 23 passes through the first connecting hole 22a and the second connecting hole 212b, and connects the fixing member 22 with the other one of the front cover body 11 and the rear cover body 12. It can be understood that the second connecting hole 212b is coaxially arranged with the first connecting hole 22a, so that in the connected state, the locking member 23 can pass through the connecting seat 21 and the fixing member 22 at the same time, and realize the installation and positioning effect of the connecting seat 21 and the fixing member 22. In addition, the second connecting hole 212b of the connecting seat 21 also cooperates with the locking member 23 for installation, which can enhance the shear resistance between the locking member 23 and the connecting seat 21, and the locking stress between the fixing member 22 and the locking member 23 can also be correspondingly dispersed, thereby reducing the risk of deformation at the connection.

[0054] In some of the above embodiments, the hardness of the fixing member 22 is stronger than the hardness of the connecting seat 21. When the locking member 23 is sequentially arranged through the second connecting hole 212b of the connecting seat 21 and the first connecting hole 22a of the fixing member 22, the fixing member 22 can provide certain support and strengthening effect for the connecting seat 21, reduce the wear of the connecting seat 21 and the fixing member 22 by the locking member 23 during the multiple disassembly and assembly processes, and further improve the durability of the mesh cover 100 during the multiple disassembly and assembly processes.

[0055] Specifically, referring to Figure 4 or Figure 6 , two first buckles 213 are arranged in the mounting groove 212a in an interval. In the connected state, the two first buckles 213 clamp the fixing member 22. The two first buckles 213 are arranged in an interval to form a mounting space, so that the fixing member 22 can be clamped between the two first buckles 213 through the interval between the two first buckles 213, and a multi-point clamping layout is formed, thereby uniformly distributing the stress between the two buckles and the fixing member 22 itself. In the actual installation process, the fixing member 22 is inserted into the mounting groove 212a through the gap between the two first buckles 213, and the two first buckles 213 lock the fixing member 22. In the state without external force, the fixing member 22 is prevented from being pulled out of the mounting groove 212a, and the cooperation stability of the fixing member 22 and the mounting groove 212a is improved.

[0056] In some embodiments, the number of first buckles 213 can be one or more. One first buckle 213 cooperates with the groove wall of the mounting groove 212a to limit the fixing member 22; and multiple first buckles 213 can limit the fixing member 22 from multiple directions. The present application does not limit this, and the detachable effect between the fixing member 22 and the connecting seat 21 can be achieved.

[0057] In addition, in the connected state, the slot of the mounting groove 212a faces the inside of the cover body 1, so as to arrange the mounting groove 212a and the fixing member 22 mounted in the mounting groove 212a towards the inside of the cover body 1. When the outside contacts the cover body 1, it cannot directly contact the mounting groove 212a and the fixing member 22, so as to ensure that the fixing member 22 can be stably installed and will not be easily pulled out, and the flatness of the side of the first connecting structure 2 facing the outside in appearance is ensured.

[0058] Please refer to Figures 4 to 6The first clamping hook 214 is arranged on the connecting base 21 and clamps the other one of the front cover body 11 and the rear cover body 12 in the connected state. The first clamping hook 214 can realize the connection between the connecting base 21 and the other one of the front cover body 11 and the rear cover body 12. In the actual installation process of the above embodiment, the fixing member 22 is first installed in the installation groove 212a, then the connecting base 21 is moved to clamp and connect the first clamping hook and the other one of the front cover body 11 and the rear cover body 12, and then the locking member 23 is installed in the connecting base 21, the fixing member 22 and the other one of the front cover body 11 and the rear cover body 12, thereby realizing the assembly and installation between the front cover body 11 and the rear cover body 12. In the above installation process, the first clamping hook 214 can realize the pre-fixing between the connecting base 21 and the other one of the front cover body 11 and the rear cover body 12, facilitate the subsequent installation and cooperation of the locking member 23, and simplify the operation of the user.

[0059] Specifically, the connecting base 21 is provided with the first clamping hook 214, and the other one of the front cover body 11 and the rear cover body 12 connected with the connecting base 21 is provided with a corresponding matching hole 14. The user can operate the connecting base 21 to approach one of the front cover body 11 and the rear cover body 12 connected with the connecting base 21, and make the first clamping hook 214 inserted into the matching hole 14, and the clamping hook part of the first clamping hook 214 can be attached to the hole wall of the matching hole 14, thereby realizing the limiting cooperation of the first clamping hook 214, fixing and installing the connecting base 21 on one of the front cover body 11 and the rear cover body 12, and realizing the fixing effect between the front cover body 11 and the rear cover body 12.

[0060] In other embodiments, the clamping connection between the connecting base 21 and the other one of the front cover body 11 and the rear cover body 12 can also be realized by buckles, matching members and the like, which are not limited in the present application.

[0061] In other embodiments, please refer to Figures 7 to 11 The installation groove 212a extends in a direction at an angle with the extension direction of the first connecting hole 22a, and the first connecting hole 22a is located outside the installation groove 212a. In the embodiment of the present application, the fixing member 22 is detachably connected with the installation groove 212a, and the fixing member 22 is used to connect with the other one of the front cover body 11 and the rear cover body 12, thereby realizing the detachable connection between the front cover body 11 and the rear cover body 12.

[0062] Specifically, please refer to Figure 11The fixing member 22 is spaced apart from the two second buckles 221, and in the connected state, the two second buckles 221 are located in the mounting groove 212a and clamped on the connecting seat 21. In some embodiments, the number of mounting grooves 212a is two, corresponding to the two second buckles 221 respectively, and the two second buckles 221 are clamped in the two mounting grooves 212a respectively, so that the fixing member 22 and the connecting seat 21 can be detachably connected. It can be understood that the clamping hook parts of the two second buckles 221 are protrudingly arranged in directions away from each other, and the two second buckles 221 respectively extend into the two mounting grooves 212a and are clamped with the groove walls of the two mounting grooves 212a, so as to realize the symmetrical clamping arrangement between the fixing member 22 and the connecting seat 21. When the fixing member 22 is subjected to a pulling force, the two second buckles 221 on both sides can evenly share the load, thereby effectively avoiding the disengagement between the fixing member 22 and the connecting seat 21, and ensuring the stability of the connection between them.

[0063] In other embodiments, the second buckle 221 has elasticity, so that in the installation and disassembly process, the second buckle 221 deforms under stress, facilitating the installation or disassembly of the second buckle 221 relative to the mounting groove 212a.

[0064] In some other embodiments, the two mounting grooves 212a of the connecting seat 21 respectively penetrate the side wall of the connecting seat 21 along the direction of spacing therebetween, so that at least part of the clamping hook parts of the two second buckles 221 can be exposed through the opening of the mounting groove 212a on the side wall of the connecting seat 21. When it is necessary to separate the fixing member 22 and the connecting seat 21, the second buckle 221 can be pressed through the opening, so that the second buckle 221 deforms and comes out, thereby realizing the quick separation between the fixing member 22 and the connecting seat 21, and simplifying the disassembly operation.

[0065] In addition, the fixing member 22 further comprises a positioning column 222, which is arranged between the two second buckles 221, and the connecting seat 21 comprises a mounting hole 215 located between the two mounting grooves 212a, and the positioning column 222 is inserted into the mounting hole 215. It can be understood that the positioning column 222 can serve as a positioning reference, on the one hand, it can guide the two second buckles 221 to be aligned with the two mounting grooves 212a during the initial installation of the fixing member 22 and the connecting seat 21, thereby reducing the number of repeated adjustments and realizing the quick assembly of the fixing member 22 and the connecting seat 21, on the other hand, when the fixing member 22 and the connecting seat 21 are assembled, the positioning column 222 can share part of the structural stress and improve the overall connection reliability, so as to ensure that the connection between the fixing member 22 and the connecting seat 21 has the ability to resist vibration or accidental impact, and improve the connection stability between the fixing member 22 and the connecting seat 21.

[0066] In addition, the fixing member 22 is further provided with a second hook 223, which hooks the other one of the front cover body 11 and the rear cover body 12 in the connected state, and the second hook 223 can realize the connection between the fixing member 22 and the other one of the front cover body 11 and the rear cover body 12. In the actual installation process of the above embodiment, first, the fixing member 22 is installed in the installation groove 212a, then the fixing member 22 is moved to make the second hook 223 and the other one of the front cover body 11 and the rear cover body 12 be connected, and then the locking member 23 is installed in the fixing member 22 and the other one of the front cover body 11 and the rear cover body 12, so as to realize the assembly and installation between the front cover body 11 and the rear cover body 12. In the above installation process, the second hook 223 can play a role in pre-fixing between the fixing member 22 and the other one of the front cover body 11 and the rear cover body 12, which can facilitate the subsequent installation and cooperation of the locking member 23, and simplify the operation of the user.

[0067] Specifically, the fixing member 22 is provided with a second hook 223, and the other one of the front cover body 11 and the rear cover body 12 connected with the fixing member 22 is provided with a corresponding matching hole 14. The user can operate the fixing member 22 to approach one of the front cover body 11 and the rear cover body 12 connected with the fixing member 22, and make the second hook 223 be inserted into the matching hole 14, and the hooking part of the second hook 223 can be attached to the hole wall of the matching hole 14, so as to realize the limiting cooperation of the second hook 223, fix and install the fixing member 22 on one of the front cover body 11 and the rear cover body 12 connected with the fixing member 22, and realize the fixing effect between the front cover body 11 and the rear cover body 12.

[0068] Please refer to Figures 7 to 10 The other one of the front cover body 11 and the rear cover body 12 is provided with a third connecting hole 13, and in the connected state, the locking member 23 passes through the first connecting hole 22a and the third connecting hole 13 to connect the fixing member 22 with the other one of the front cover body 11 and the rear cover body 12. In the above embodiment, the third connecting hole 13 and the first connecting hole 22a are coaxially and alignedly arranged, so that the locking member 23 forms a through hole through the fixing member 22 and one of the front cover body 11 and the rear cover body 12 connected with the fixing member 22, thereby prolonging the effective contact length of the locking member 23 with one of the front cover body 11 and the rear cover body 12 connected with the fixing member 22, and strengthening the fastening effect.

[0069] Further, the front cover body 11 and the rear cover body 12 are rigidly connected through the locking member 23, so as to effectively reduce the probability of connection loosening caused by vibration or external factors, and the locking member 23 simultaneously acts on the fixing member 22 and the cover body 1, so as to uniformly distribute the locking pressure and avoid deformation or fracture caused by local stress concentration.

[0070] Please refer to Figures 3 to 10The first connecting structure 2 further has a release state, in which the locking member 23 moves in the first connecting hole 22a to release the connection between the fixing member 22 and the other of the front cover body 11 and the rear cover body 12.

[0071] It can be understood that the locking member 23 moves in the first connecting hole 22a to break the connection between the locking member 23 and the cover body 1. In this state, the locking member 23 is at least partially connected with the fixing member 22 in the first connecting hole 22a, or the locking member 23 is completely separated from the fixing member 22. The above-mentioned state can achieve the disassembly of the front cover body 11 and the rear cover body 12, which is not limited in the present application.

[0072] In addition, in the connection state, the deformation part 211 is used to connect one of the front cover body 11 and the rear cover body 12, and the deformation part 211 is further detachably connected with the fixing member 22, and the fixing member 22 is connected with the other of the front cover body 11 and the rear cover body 12, so as to achieve the connection of the front cover body 11 and the rear cover body 12. In the release state, the deformation part 211 is connected with one of the front cover body 11 and the rear cover body 12, and the locking member 23 moves in the first connecting hole 22a to release the connection between the fixing member 22 and the other of the front cover body 11 and the rear cover body 12, so as to achieve the disassembly of the front cover body 11 and the rear cover body 12.

[0073] For example, in the connection state, the deformation part 211 is connected with the front cover body 11, and the fixing member 22 is connected with the rear cover body 12; in the release state, the deformation part 211 is connected with the front cover body 11, and the fixing member 22 is released from the connection with the rear cover body 12. Alternatively, in the connection state, the deformation part 211 is connected with the rear cover body 12, and the fixing member 22 is connected with the front cover body 11; in the release state, the deformation part 211 is connected with the rear cover body 12, and the fixing member 22 is released from the connection with the front cover body 11.

[0074] The above-mentioned design that the deformation part 211 can be deformed under the action of external force can allow the position of the fixing member 22 to change, and thus can achieve the connection or release of the fixing member 22 with the corresponding front cover body 11 or rear cover body 12. In some embodiments, when it is required to release the connection between the fixing member 22 and the corresponding front cover body 11 or rear cover body 12, an external force can be applied to the fixing member 22, so that the deformation part 211 is deformed, and the position of the fixing member 22 can move relative to the corresponding front cover body 11 or rear cover body 12, and thus the connection between the fixing member 22 and the corresponding front cover body 11 or rear cover body 12 is released. Conversely, the connection between the fixing member 22 and the corresponding front cover body 11 or rear cover body 12 can be achieved.

[0075] The deformation part 211 can deform, that is, the fixing part 22 can be connected or disconnected with the corresponding front cover body 11 or rear cover body 12. Compared with the related art of designing a rotating shaft, the design is beneficial to the structural simplification and installation mode simplification of the mesh cover 100, and is convenient for subsequent maintenance.

[0076] In some embodiments, the deformation part 211 does not need to additionally increase other movable parts (such as springs, sliding blocks or rotating shafts), and only through the resetting and deformation of a single structure, the first connecting structure 2 can realize the switching between the connected state and the released state, which simplifies the assembly process, reduces the hidden troubles caused by complex mechanisms, improves the disassembly and assembly convenience, and maintains the reliability of the overall structure of the mesh cover 100.

[0077] Specifically, the deformation of the deformation part 211 can be compression, elongation, bending or rotation, and the present application is not limited herein, as long as the connection effect between the fixing part 22 and the other one of the front cover body 11 and the rear cover body 12 can be met.

[0078] In some embodiments, the connecting seat 21 is connected with one of the front cover body 11 and the rear cover body 12 through the deformation part 211, and the deformation part 211 and the connected one of the front cover body 11 and the rear cover body 12 are an integral molding structure. That is, in the production and manufacturing process of the front cover body 11 or the rear cover body 12, according to the material selection of the front cover body 11, the rear cover body 12 and the deformation part 211, the deformation part 211 and the front cover body 11 or the rear cover body 12 can be integrally molded by injection molding, stamping or other methods. Specifically, when the deformation part 211 and the front cover body 11 or the rear cover body 12 are plastic materials, they can be integrally molded by injection molding, and when the deformation part 211 and the front cover body 11 or the rear cover body 12 are metal materials, they can be integrally molded by stamping, and the present application is not limited herein. It can be understood that the deformation part 211 does not need to be subsequently assembled with the front cover body 11 or the rear cover body 12, thereby reducing the production steps and improving the assembly efficiency. In addition, the integral molding structure of the deformation part 211 and the front cover body 11 or the rear cover body 12 can also reduce the number of corresponding parts, and further improve the production efficiency.

[0079] And, since the deformation portion 211 needs to be deformed by force, the connection stability between the deformation portion 211 and the front cover body 11 or the rear cover body 12 is particularly important. The one-piece structure of the deformation portion 211 and the front cover body 11 or the rear cover body 12 ensures the continuity and stability of the structure. Since there is no fixed point of the split structure between the deformation portion 211 and the front cover body 11 or the rear cover body 12, potential weak links are effectively reduced. For example, when the deformation portion 211 is integrally formed with the front cover body 11 or the rear cover body 12, the connection area between the deformation portion 211 and the front cover body 11 or the rear cover body 12 is continuously and uniformly distributed. When the deformation portion 211 is deformed by pressure, the stress at the end of the deformation portion 211 is uniformly dispersed to the local area of the front cover body 11 or the rear cover body 12 through the material itself ductility, thereby uniformly dispersing the stress, further significantly improving the fatigue resistance, and ensuring the stability and reliability of the overall structure.

[0080] Please refer to Figure 10 In some embodiments, the deformation portion 211 includes a spring sheet 211a, and the thickness of the spring sheet 211a is H, where 0.5mm≤H≤2mm. In the embodiments of the present application, the deformation portion 211 includes a spring sheet 211a, which has a relatively thin thickness, is arranged in a sheet shape, and has a certain degree of elasticity. Therefore, the spring sheet 211a can be deformed, such as bending, under the driving of external force. One end of the spring sheet 211a is used to connect one of the front cover body 11 and the rear cover body 12, and the other end of the spring sheet 211a is connected with the fixing member 22. The spring sheet 211a is deformed by force to change the spatial position state of the fixing member 22, thereby achieving the assembly between the fixing member 22 and the cover body 1. In some embodiments, the spring sheet 211a can restore to the original state without the driving of external force. When the assembly between the fixing member 22 and the cover body 1 is released, the spring sheet 211a has a certain self-resetting function.

[0081] In the embodiments of the present application, the material of the spring sheet 211a includes any one of metal, polypropylene (PP), nylon (PA66), and the like. The present application is not limited herein, as long as the spring sheet 211a has a certain elasticity and does not break under the action of external force.

[0082] Please continue to refer to Figures 3 to 10 The spring sheet 211a in the embodiments of the present application is in an arc transition. When the spring sheet 211a is stressed, the stress at the connection thereof can be uniformly diffused through the arc transition, thereby further reducing the risk of breaking of the spring sheet 211a under stress.

[0083] Further, the thickness of the elastic sheet 211a in the embodiment of the present application is set as H, 0.5mm≤H≤2mm, that is, the thickness of the elastic sheet 211a ranges from 0.5mm to 2mm. By setting the thickness H of the elastic sheet 211a within the above range, the elastic sheet 211a can provide good flexibility while maintaining sufficient strength, and can smoothly deform under pressure when it is necessary to install the fixing member 22 in cooperation with the other of the front cover body 11 and the rear cover body 12, thereby achieving cooperation between the fixing member 22 and the other of the front cover body 11 and the rear cover body 12, and when the cooperation between the fixing member 22 and the other of the front cover body 11 and the rear cover body 12 is released, the elastic sheet 211a can restore to a certain extent, so as to facilitate subsequent operation.

[0084] In addition, the elastic sheet 211a with a thickness ranging from 0.5mm to 2mm has high durability, can reduce the risk of failure due to material fatigue, and can maintain the original performance even after being disassembled and assembled multiple times, thereby ensuring long-term reliable connection between the front cover body 11 and the rear cover body 12.

[0085] Similarly, the elastic sheet 211a within the above thickness range is neither too hard to be inconvenient to operate nor too soft to lose its original elasticity, thereby facilitating the user to manually operate the first connecting structure 2 to disassemble and assemble the front cover body 11 and the rear cover body 12.

[0086] In some embodiments, the connecting seat 21 further comprises a connecting portion 212 connected to the deformation portion 211, and the connecting portion 212 is detachably connected to the fixing member 22 in the connected state. It can be understood that the connecting portion 212 is used for detachable assembly with the fixing member 22, and the deformation portion 211 and the connecting portion 212 can be integrally formed, so that the connecting portion 212 has a certain elasticity, thereby making the detachable assembly of the connecting portion 212 and the fixing member 22 more flexible, and achieving repeated disassembly and assembly without being easily damaged, thereby having good durability.

[0087] Please refer to Figure 12 , the mesh cover 100 further comprises a self-locking structure 3 connected to one of the front cover body 11 and the rear cover body 12 protruding from the connecting seat 21, and the connecting seat 21 comprises two deformation portions 211 arranged at intervals; in the connected state, the self-locking structure 3 is located between the two deformation portions 211 and abuts against the connecting portion 212 in the first direction X, and the first direction X is arranged at an angle with the extension direction of the first connecting hole 22a.

[0088] Specifically, the self-locking structure 3 is connected to one of the front cover body 11 and the rear cover body 12 connected by the first connecting structure 2, so that when the fixing part 22 of the first connecting structure 2 is connected to the other one of the front cover body 11 and the rear cover body 12, the self-locking structure 3 can abut along the first direction X and the connecting part 212 at the gap between the two deformation parts 211, achieving the limiting effect on the connecting seat 21. On the one hand, the self-locking structure 3 can block the connecting part 212, so that the connecting part 212 rotates by a proper angle to drive the fixing part 22 to rotate by a proper angle, thereby realizing the connection state with the other one of the front cover body 11 and the rear cover body 12, and similarly, the subsequent operation of separating the fixing part 22 and the other one of the front cover body 11 and the rear cover body 12 can also be facilitated. On the other hand, the self-locking structure 3 can limit the connecting part 212, reduce the influence of the restoring force of the deformation part 211 after deformation, and pre-position the connecting part 212 and the other one of the front cover body 11 and the rear cover body 12, thereby ensuring the smooth connection between the connecting part 212 and the other one of the front cover body 11 and the rear cover body 12.

[0089] It can be understood that the angle between the first direction X and the extension direction of the first connecting hole 22a can be 90°, or other acute angles, which are not limited in the present application, and can achieve the blocking and limiting effects.

[0090] In some other embodiments, the number of deformation parts 211 is one, and the self-locking structure 3 and the connecting part 212 abut in the first direction X in the connected state. The first direction X forms an angle with the extension direction of the first connecting hole 22a. The self-locking structure 3 abuts against the top surface of the connecting part 212, giving the connecting part 212 a pressure in the first direction X. Since the deformation part 211 is connected to the connecting part 212, the deformation part 211 can also be subjected to this pressure in the first direction X, which can partially offset the elastic force of the deformation part 211, thereby preventing the fixing part 22 from being pulled out in the opposite direction.

[0091] Please refer to Figures 3 to 10 In the connected state, the end of the first connecting structure 2 away from the deformation part 211 is tilted away from the cover body 1. It can be understood that the tilted part can provide a part for the user to easily grasp and apply force, especially during the disassembly of the mesh cover 100. The user can hold the tilted part to release the locking between the fixing part 22 and the cover body 1, thereby facilitating the user to directly disassemble the front cover body 11 and the rear cover body 12 by manual operation, and facilitating the daily maintenance of the mesh cover 100.

[0092] In the embodiments of the present application, the first connecting structure 2 is arranged at the outer periphery of the cover body 1. The first connecting structure 2 is connected to the outside of the cover body 1 along the periphery of the cover body 1. When the user operates the first connecting structure 2, there is no obstruction and blockage of any other structure, and the user can directly operate the connecting seat 21, the fixing member 22 and the locking member 23 of the first connecting structure from the outside, thereby improving the convenience of operation, for example, the connecting seat 21 and the fixing member 22 can be directly operated; the fixing member 22 is pressed from the outside to be close to the cover body 1; the locking member 23, the fixing member 22 and the cover body 1 are directly connected from the outside, and the like.

[0093] In some embodiments, the number of the first connecting structure 2 is multiple, and the multiple first connecting structures 2 are spaced and uniformly distributed along the periphery of the cover body 1, which simplifies the installation process of the front cover body 11 and the rear cover body 12, and facilitates the stable assembly between the front cover body 11 and the rear cover body 12.

[0094] In some embodiments, referring to Figures 3 to 10 , the mesh cover 100 further comprises a second connecting structure 4, the second connecting structure 4 is arranged at the outer periphery of the cover body 1 and is arranged opposite to the first connecting structure 2 along the radial direction of the cover body 1, and the second connecting structure 4 connects the front cover body 11 and the rear cover body 12. By increasing the second connecting structure 4, multiple point fixing between the front cover body 11 and the rear cover body 12 is formed, which can effectively disperse the fixing stress between the first connecting structure 2 and the front cover body 11 and the rear cover body 12, and ensure the connection stability of the front cover body 11 and the rear cover body 12. Moreover, the second connecting structure 4 and the first connecting structure 2 are arranged opposite along the radial direction of the cover body 1, so that the cover body 1 can share the stress through the first connecting structure 2 and the second connecting structure 4 when subjected to external force, and the effect of two-point positioning is achieved, which improves the connection stability and reduces the misalignment phenomenon between the front cover body 11 and the rear cover body 12.

[0095] In some embodiments, the second connecting structure 4 and the first connecting structure 2 are consistent in structure. Further, the number of the first connecting structure 2 and the second connecting structure 4 is multiple, and they are uniformly distributed along the periphery of the cover body 1, thereby achieving the effect of multiple-point positioning between the front cover body 11 and the rear cover body 12.

[0096] In addition, in some other embodiments of the present application, the first connecting structure 2 and the second connecting structure 4 are simultaneously connected with the front cover body 11, or the first connecting structure 2 and the second connecting structure 4 are simultaneously connected with the rear cover body 12, or the first connecting structure 2 and the second connecting structure 4 are respectively connected with the front cover body 11 and the rear cover body 12. It can be understood that the first connecting structure 2 is integrally connected with the front cover body 11 or the rear cover body 12, and the second connecting structure 4 is clamped connected with the front cover body 11 or the rear cover body 12.

[0097] In the actual installation process, the second connecting structure 4 comprises a buckle and a buckle position, wherein the buckle and the buckle position are arranged at the front cover body 11 and the rear cover body 12 respectively, in the process of installing the cover body 1, the buckle is inserted into the buckle position, thereby realizing the preliminary positioning effect of the front cover body 11 and the rear cover body 12, ensuring the alignment of the corresponding parts of the first connecting structure 2 and the cover body 1, then the first connecting structure 2 is operated, the deformed part 211 is deformed, the fixing part 22 is close to the cover body 1 and is installed in cooperation with the cover body 1, so as to realize the cooperation and locking between the front cover body 11 and the rear cover body 12, while ensuring the alignment and installation of the front cover body 11 and the rear cover body 12, the operation difficulty of the user is reduced, and the stability and anti-interference capability of the cover body 1 are improved.
