[0032] The card hole 22 is opened at the root position of the extended portion 21, the elastic buckle 11 is clamped in the card hole 22, and the extended portion 21 abuts against the root position of the elastic buckle 11.

[0033] From the above description, it can be seen that the beneficial effects of the present utility model are as follows:

[0034] Quick fastening mechanism: By means of the elastic buckle 11 provided at the top of the shielding frame 1, the quick fastening of the cover plate 2 is achieved, and the assembly can be completed without using tools, significantly improving the assembly efficiency and convenience.

[0035] Enhanced structural stability: The card holes 22 on the cover plate 2 cooperate with the elastic buckles 11 on the shielding frame 1 to form a mechanical locking mechanism, ensuring that the cover plate 2 is more stably fixed on the shielding frame 1, reducing the problem of structural instability caused by loose or damaged fasteners; and the extension part 21 abuts against the root position of the elastic buckle 11, which can enhance the structural strength of the elastic buckle 11 and reduce the risk of fracture of the elastic buckle 11.

[0036] Simplified maintenance process: Since the installation and disassembly of the cover plate 2 no longer depend on screws or other fasteners, maintenance personnel can replace or inspect the cover plate 2 more quickly, reducing the maintenance cost and time.

[0037] Improved durability and reliability: The design of the elastic buckle 11 reduces the dependence on traditional fasteners, avoiding maintenance problems caused by loose or corroded fasteners, thereby improving the durability and reliability of the shielding cover.

[0038] Optimized production efficiency: The simplified fastening structure is easy to realize automated assembly, which helps to improve the automation level of the production line, reduce manual intervention, and improve production efficiency.

[0039] Enhanced user experience: Users can easily install and disassemble the cover plate 2 without professional tools, improving the use convenience and enhancing the user experience.

[0040] Improved product aesthetics: Since the use of traditional fasteners is omitted, the surface of the cover plate 2 is cleaner, enhancing the overall aesthetics of the product, especially suitable for application scenarios with high requirements for appearance design.

[0041] Wide adaptability: The design of this fastening structure allows adjustment according to different shielding cover sizes and shapes, with good adaptability and versatility, suitable for various specifications of shielding covers.

[0042] Reduced assembly errors: The simplified assembly process reduces possible errors in the assembly process, such as missing fasteners and inconsistent tightening torques, improving the consistency and accuracy of assembly.

[0043] Furthermore, the extension part 21 is provided with a contact part 23 extending outward, and the contact part 23 abuts against the root of the elastic buckle 11.

[0044] As can be seen from the above description, the outer contact part 23 of the extension part 21 increases the contact area between the cover plate 2 and the elastic buckle 11, improving the fastening stability.

[0045] Further, a forming hole 24 is also formed in the cover plate 2, and the extending portion 21 is located in the forming hole 24.

[0046] As can be seen from the above description, the design of the forming hole 24 facilitates the processing and forming of the extending portion 21 and is also beneficial to heat dissipation.

[0047] Further, the number of the elastic buckles 11 is multiple.

[0048] As can be seen from the above description, the use of multiple elastic buckles 11 improves the connection strength between the cover plate 2 and the shielding frame 1, making the overall structure more firm.

[0049] Further, the multiple elastic buckles 11 are symmetrically distributed about the center on the shielding frame 1.

[0050] As can be seen from the above description, the central symmetric distribution of the elastic buckles 11 helps to evenly distribute the force received by the cover plate 2, avoid local stress concentration, and thus improve the stability of the structure.

[0051] Further, an identification layer is provided at the root position of the extending portion 21. When the elastic buckle 11 is clamped in the clamping hole 22, the elastic buckle 11 covers the identification layer.

[0052] As can be seen from the above description, the setting of the identification layer provides a visual or tactile hint to help the user correctly align the clamping hole 22 and the elastic buckle 11, simplifying the installation process.

[0053] Further, the material of the identification layer is a reflective material.

[0054] As can be seen from the above description, the identification layer of the reflective material is more conspicuous under light irradiation, improving the recognition degree under different lighting conditions and facilitating quick positioning and installation.

[0055] Further, a bent and formed edge guard 25 is also provided at the edge of the cover plate 2, and the edge guard 25 is located outside the extending portion 21.

[0056] As can be seen from the above description, the design of the edge guard 25 provides additional edge protection for the cover plate 2, preventing deformation or damage caused by external forces and enhancing the durability of the cover plate 2.

[0057] Further, the edge guard 25 abuts against the top of the shielding frame 1.

[0058] As can be seen from the above description, the abutment of the edge guard 25 against the top of the shielding frame 1 provides an additional support point, further improving the stability of the cover plate 2 and also helping to prevent the cover plate 2 from sliding or shifting on the shielding frame 1.

More specifically, the extended portion 21 is provided with a contact portion 23 extending outward therefrom, and the contact portion 23 abuts against the root of the elastic buckle 11.
