Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-8 , an embodiment provided by the present invention:

[0029] A high-frequency signal shielding reinforcement device includes a shell 1, two groups of slots 11 are opened on the surface of the shell 1, two groups of shielding plates 12 are fixedly connected to the side of the shell 1 near the slot 11, two groups of slots 13 are opened at the bottom of the shell 1, two groups of shielding plates 14 are fixedly connected to the bottom of the shell 1, a slide groove 15 is opened on both sides of the shell 1, a circular groove 16 is opened on the inner side of the slide groove 15, an installation cavity 17 is opened inside the shell 1, and blocks 18 are fixedly connected to both sides of the inner wall of the installation cavity 17, a protective structure 2 is provided on the outside of the shell 1, the protective structure 2 includes a protective shell 21, a protective cavity 22 is opened inside the protective shell 21, fixed blocks 23 are fixedly connected to both sides of the protective shell 21, and the surface of the fixed block 23 is fixedly connected to the connecting plate 2 4. The surface of the connecting plate 24 is provided with a second slide groove 25, and the interior of the second slide groove 25 is slidably connected to a connecting rod 26. The surface of the connecting rod 26 is fixedly connected to a limit block 27. The surface of the connecting rod 26 is fixedly connected to a slider 28. The interior of the slider 28 is slidably connected to a fixed rod 29. The outer side of the fixed rod 29 is sleeved with a spring 210. The surface of the protective shell 21 is symmetrically fixedly connected to a magnetic plug 211. The interior of the shell 1 is provided with an anti-interference structure 3, and the anti-interference structure 3 includes an interface 31. One end of the interface 31 is fixedly connected to a circuit board 32. One end of the circuit board 32 is fixedly connected to a power cord 33. The outer side of the circuit board 32 is sleeved with a shielding cover 34. The surface of the shielding cover 34 is fixedly connected to a connecting portion 35. The surface of the connecting portion 35 is fixedly connected There is a shielding ring 36, and a snap-in groove 37 is opened on both sides of the shielding cover 34. An anti-interference structure 3 is set. By sleeved on the outside of the circuit board 32 and the power line 33, the shielding cover 34 and the shielding ring 36 are formed around the circuit board 32 and the power line 33 in the installation cavity 17. A circle of tight shielding layer is formed, which effectively shields the interference of external signal radiation. At the same time, it also shields the signal radiated by the circuit board 32 when transmitting data to prevent interference with other devices. The shielding cover 34 is snapped into the installation cavity 17 through the snap-in groove 37 and the card block 18. It is more convenient to install, improves production efficiency, optimizes production costs, and avoids interference in signal transmission caused by copper foil damage. Shielding plates 12 and 2, 14 are provided on the outside of slot 13. Shielding plates 12 and 2, 14 separate slot 11, slot 2, and mounting cavity 17 from each other, reducing the possibility that the magnetic plug-in block 211 and the magnetic materials in slot 11 and slot 2, 13 may affect the internal components of mounting cavity 17. A protective structure 2 is provided. By rotating and adjusting the position of the protective shell 21, the interface 31 is plugged into the protective cavity 22 inside the protective shell 21, so that the surface of the interface 31 can be protected when not in use, preventing it from being exposed to the outside for a long time and being corroded by dust and water vapor in the air, thereby reducing the service life of the interface 31. Through the cooperation of the spring 210, the magnetic plug-in block 211 and slot 11,The protective shell 21 can be fixed to one side of the housing 1 to prevent it from slipping off. When the interface 31 needs to be used, the protective shell 21 can be rotated and adjusted to the bottom of the housing 1 to avoid blocking the interface 31. The protective shell 21 can be fixed to the bottom of the housing 1 through the cooperation of the slot 2 13 and the magnetic plug 211. At this time, the housing 1 can also be placed more conveniently, making it more convenient to use.

[0030] Furthermore, the size of the magnetic plug-in block 211 matches the slot one 11 and the slot two 13, and the interior of the slot one 11 and the slot two 13 is provided with magnetic materials that cooperate with the magnetic plug-in block 211. By inserting the magnetic plug-in block 211 into the slot one 11 and the slot two 13, and cooperating with the magnetic materials inside the two, the protective shell 21 can be fixed to the outside of the interface 31 or the bottom of the shell 1, thereby meeting different usage requirements.

[0031] Furthermore, shielding plate 1 12 and shielding plate 2 14 are both L-shaped, and shielding plate 1 12 and shielding plate 2 14 are respectively arranged on the outside of slot 1 11 and slot 2 13. Shielding plate 1 12 and shielding plate 2 14 separate slot 1 11, slot 2 13 and mounting cavity 17 from each other, thereby reducing the possibility of the magnetic plug 211 and the magnetic materials in slot 1 11 and slot 2 13 affecting the internal components of the mounting cavity 17.

[0032] Furthermore, the two ends of the fixed rod 29 are fixedly connected to the inner wall of the slide groove 15 and the inner wall of the circular groove 16 respectively, and the slider 28 is slidably connected in the slide groove 15. By pulling the protective shell 21, the connecting plate 24 can be pulled through the fixed block 23. When the connecting plate 24 moves, the edge of the slide groove 25 on its surface contacts the connecting rod 26, and then the slider 28 is driven by the connecting rod 26 to move in the slide groove 15 on the fixed rod 29, thereby compressing the spring 210. The connecting plate 24 is a rotatable structure on the connecting rod 26, so that the protective shell 21 can be rotated and adjusted around the connecting rod 26.

[0033] Furthermore, the cross section of the circular groove 16 is an inscribed circle of the cross section of the slide groove 15 . The circular groove 16 limits the slider 28 so that the slider 28 can only slide in the slide groove 15 and cannot slide into the circular groove 16 .

[0034] Furthermore, the two ends of the spring 210 are fixedly connected to the surface of the slider 28 and the inner wall of the circular groove 16 respectively. When there is no external force, the elastic force of the spring 210 will cause the slider 28 on the fixed rod 29 to have a tendency to move toward the side of the slide groove 15 away from the spring 210. When the spring 210 is deformed, the inner surface of the spring 210 and the outer surface of the fixed rod 29 will not interfere with each other.

[0035] Furthermore, the radius of the limit block 27 is greater than the radius of the connecting rod 26, and the connecting rod 26 is movably connected in the second slide groove 25, which limits the movement of the connecting plate 24, so that the connecting plate 24 can only slide and rotate on the surface of the connecting rod 26 through the second slide groove 25, and will not fall off the surface of the connecting rod 26.

[0036] Furthermore, one end of the interface 31 passes through the installation cavity 17 and is inserted into the protective cavity 22, the power cord 33 passes through the other end of the installation cavity 17, the power cord 33 is fixedly connected to the outer shell 1, the interface 31 and the power cord 33 are respectively fixedly connected to the two ends of the outer shell 1, and the shielding cover 34 and the shielding ring 36 are sleeved on the outside of the circuit board 32 and the power cord 33.

[0037] Furthermore, the shielding ring 36 is sleeved on the surface of the power cord 33, and the surface of the shielding ring 36 is in contact with the inner wall surface of the installation cavity 17 away from the interface 31. By sleeved on the outside of the circuit board 32 and the power cord 33, the shielding cover 34 and the shielding ring 36 are formed around the circuit board 32 and the power cord 33 in the installation cavity 17. A tight shielding layer is formed around the circuit board 32 and the power cord 33 in the installation cavity 17, which effectively shields the interference of external signal radiation, and also shields the signal radiated by the circuit board 32 when transmitting data to prevent interference to other devices.

[0038] Furthermore, the surface of the clamping block 18 is arc-shaped, and the clamping block 18 is clamped in the inside of the clamping groove 37. The shielding cover 34 is clamped in the installation cavity 17 through the cooperation between the clamping groove 37 and the clamping block 18, which is more convenient during installation.

[0039] Working principle: When the interface 31 is needed, the protective shell 21 is pulled, and the connecting plate 24 can be pulled through the fixed block 23. When the connecting plate 24 moves, the edge of the slide groove 25 on its surface contacts the connecting rod 26, and then the slider 28 is driven by the connecting rod 26 to move in the slide groove 15 on the fixed rod 29, thereby compressing the spring 210. The connecting plate 24 is a rotatable structure on the connecting rod 26, and the protective shell 21 can be rotated and adjusted around the connecting rod 26. The protective shell 21 is rotated and adjusted to the bottom of the shell 1, and the protective shell can be adjusted by cooperating with the slot 2 13 and the magnetic plug 211. The protective shell 21 is fixed to the bottom of the shell 1, which can also facilitate the placement of the shell 1. When the interface 31 is not needed, the position of the protective shell 21 is rotated and adjusted so that the interface 31 is plugged into the protective cavity 22 inside the protective shell 21. Therefore, when not in use, the surface of the interface 31 can be protected to prevent it from being exposed to the outside for a long time, and dust and water vapor in the air from eroding the surface of the interface 31, thereby reducing the service life of the interface 31. When there is no external force, the elastic force of the spring 210 will cause the slider 28 on the fixed rod 29 to move away from the slide groove 15. The tendency of one side of the spring 210 to move is such that the protective shell 21 can be fixed to one side of the housing 1 through the cooperation of the spring 210, the magnetic plug 211 and the slot 11 to prevent the protective shell 21 from slipping off. The shielding cover 34 and the shielding ring 36 that are sleeved on the outside of the circuit board 32 and the power line 33 form a tight shielding layer around the circuit board 32 and the power line 33 in the installation cavity 17, effectively shielding the external signal radiation interference, and also shielding the signal radiated by the circuit board 32 when transmitting data, preventing interference to other devices. The shield 34 is engaged in the mounting cavity 17 through the engagement groove 37 and the clamping block 18, which is convenient for installation, improves production efficiency, optimizes production costs, and avoids interference in signal transmission caused by damage to the copper foil. By arranging the shielding plate 12 and the shielding plate 2 14 on the outside of the slot 1 11 and the slot 2 13, the shielding plate 1 12 and the shielding plate 2 14 separate the slot 1 11, the slot 2 13 and the mounting cavity 17 from each other, reducing the possibility of the magnetic plug 211 and the magnetic materials in the slot 1 11 and the slot 2 13 affecting the internal components of the mounting cavity 17.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
