The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0020] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0021] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a computer anti-static protection circuit board of the utility model comprises a computer circuit board 1 and a plurality of shielding covers, guide rails are installed on both sides of the computer circuit board 1, the guide rails are composed of two L-shaped plates 6, and the L-shaped plates 6 are combined to form positioning grooves 7, and the shielding covers are arranged on the surface of the computer circuit board 1, and the shielding covers are composed of a top plate 2, a plurality of side plates 3 and a fixed plate 4, the side plates 3 are installed on both sides of the length direction of the top plate 2 through hinges, and the fixed plates 4 are installed on both ends of the width direction of the top plate 2, and one end of the fixed plates 4 extends to the outside of the guide rails and is bent inward to form a positioning portion 5, and the positioning portion 5 is slidably arranged in the positioning groove 7;

[0023] Wherein, the hinged part is a torsion spring hinge, and the side panel can be automatically closed by twisting the torsion spring hinge.

[0024] In this embodiment, gaps are formed between the relative end faces of the L-shaped plate 6 for the L-shaped plate 6 to move inward, and multiple positioning columns 9 are installed on the end face of the lower L-shaped plate 6. Positioning holes are provided on the end face of the upper L-shaped plate 6 opposite to the positioning columns 9, and the other ends of the positioning columns 9 are inserted into the positioning holes, so that the L-shaped plates can only open outward or move inward along the positioning columns.

[0025] In this embodiment, through holes 8 are provided on the outer wall surface of the L-shaped plate 6 facing the fixing holes of the computer circuit board 1 .

[0026] In this embodiment, one end face of the side panel 3 away from the top panel 2 is arranged in contact with the upper surface of the computer circuit board 1. The length of the side panel 3 and the top panel 2 matches the width of the computer circuit board 1. The side panel can increase the support effect of the top panel and avoid bending in the middle of the top panel.

[0027] In this embodiment, the top plate 2, multiple side plates 3 and the fixed plate 4 are all made of nickel silver. The nickel silver shielding cover is mainly used to solve the external interference problems of high frequency, electromagnetic, static electricity, etc. on the product, and also provides internal protection and motherboard protection.

[0028] In this embodiment, the width of the positioning portion 5 matches the width of the positioning groove, so that the positioning portion can be smoothly inserted into the positioning groove 7 .

[0029] In this embodiment, the guide rail is made of insulating plastic material, which avoids electrical conduction with the computer circuit board and increases safety.

[0030] During installation, the positioning part on the shielding cover can be slidably arranged in the positioning groove and move along the axial direction of the positioning groove, thereby changing the installation position of the shielding cover. In the process of moving the shielding cover, the side plate can be lifted upward with the hinge as the center, so that the side plate is flush with the top plate. The opened side plate avoids collision with the electronic components on the computer circuit board during the movement, thereby increasing safety. After moving to the specified position, the side plate can be released, so that the side plate is closed downward with the hinge as the center, thereby forming a shielding cover covering the electronic components.

[0031] When the computer circuit board is fixed, the screws can pass through the fixing holes and the through holes to lock and fix the computer circuit board in the chassis. During the locking process, the computer circuit board can press down the upper L-shaped plate, and the positioning part can be clamped and fixed by the two L-shaped plates moving inward, and the shielding cover can be fixed synchronously.

[0032] On the contrary, after the screw is removed from the through hole, the positioning portion can be moved along the positioning groove again until it is removed from the computer circuit board, which greatly facilitates disassembly and assembly.

[0033] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
