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.

[0019] 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.

[0020] 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.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a wireless network signal interference shielding device of the utility model comprises a signal shielding cover, which is divided into two parts and consists of a first half shell 1 and a second half shell 2. Grooves 9 are provided on opposite ends of the first half shell 1 and the second half shell 2. Fixing plates 3 are provided in the grooves 9. Adjusting grooves 5 are provided on the fixing plates 3. Adjusting plates 4 are slidably installed in the adjusting grooves 5. The adjusting plates 4 and the first half shell 1 or the adjusting plates 4 and the second half shell 2 are fixedly connected by hinges. Screw holes are provided on the bottom surfaces of the adjusting grooves 5. Screws 6 for fixing the fixing plates 3 and positioning the adjusting plates 4 are threadedly connected in the screw holes. The hinges are torsion spring hinges, so the first half shell and the second half shell are automatically opened upward.

[0022] In this embodiment, positioning grooves are provided on both sides of the adjustment groove 5, and the two side surfaces of the adjustment plate 4 are protruded opposite to the positioning grooves to form positioning parts, and the positioning parts are slidably set in the positioning grooves. A compression spring 7 is installed at one end of the positioning part, and the other end of the compression spring 7 is installed on the inner wall surface of the positioning groove, and the compression spring 7 is in a stretched state.

[0023] In this embodiment, the nut heads on the screws 6 enter the interior of the adjustment slots 5 and are arranged to abut against the end faces of the adjustment plate 4. The fixing plate and the signal shielding cover can be fixed to the main board through the screws. The screws can play a dual role, which can lock the fixing plate and limit the adjustment plate.

[0024] In this embodiment, a plurality of slots 8 are provided on the open end surface of the first half shell 1 , and the open end surface of the second half shell 2 protrudes opposite the slots 8 to form inserting portions 10 , which are inserted into the slots 8 .

[0025] In this embodiment, the height and width of the groove 9 match the height and width of the groove 9, so that the groove can be completely blocked by the fixing plate.

[0026] In this embodiment, one end surface of the fixing plate 3 is flush with the inner side surface of the signal shielding cover, thereby avoiding protrusion and occupying the space inside the signal shielding cover.

[0027] When disassembling, prepare a screwdriver. The head of the screwdriver can be inserted into the cross slot of the screw. After rotating the screwdriver, the screw can be driven to move upward along the screw hole. There is no need to unscrew the screw. As long as the nut head on the screw is removed from the adjustment slot, there is a moving space between the outer end surface of the adjustment plate and the screw, so that the adjustment plate can be pulled outward by the rebound of the compression spring. The movement of the adjustment plate drives the first half shell and the second half shell, so that the plug-in part on the second half shell is pulled out from the slot on the first half shell. After being pulled out, the first half shell and the second half shell can be automatically opened upward by the torsion of the torsion spring hinge, so that the internal wireless transceiver module is exposed, which is convenient for its maintenance or replacement.

[0028] Among them, after the wireless transceiver module is replaced, the first half shell and the second half shell are closed inwardly, and the first half shell and the second half shell are pushed inwardly along the adjustment groove, so that the plug on the second half shell can be inserted into the slot, so that the first half shell and the second half shell are in conflict and cannot be opened upward. At this time, the screw can be rotated again so that the nut head of the screw can enter the adjustment groove and conflict with the adjustment plate, so that the first half shell and the second half shell can always be in a conflicting state and cover the wireless transceiver module to avoid external signal interference.

[0029] 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.
