[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] Please see Figures 1 to 2 This utility model provides a technical solution: a low-voltage security device with protective components, including an identification host 1, a camera 2 installed at the top of the identification host 1, two support plates 3 fixedly connected to the top of the identification host 1, an adjustment plate 9 rotatably connected to the surface of the support plate 3, a first protective plate 4 fixedly connected to the surface of the adjustment plate 9, second protective plates 5 fixedly connected to the two sides of the first protective plate 4, a central rod 10 fixedly connected to the surface of the adjustment plate 9, a limiting plate 12 slidably connected to the surface of the central rod 10, and the limiting plate 12 is embedded in the surface of the support plate 3;

[0024] A first protective plate 4 is set at the top of the identification host 1, and a retractable second protective plate 5 is set on both sides of the first protective plate 4. The protection range can be flexibly expanded as needed to improve the adaptability of the protective components. An adjustment plate 9 and a support plate 3 are set on the surface of the first protective plate 4. The limiting plate 12 on the surface of the central rod 10 and the limiting groove 15 on the surface of the fixed plate 11 are interlocked to realize the adjustment of the angle of the protective plate. In this way, the angle of the protective plate can be adjusted according to different angles of sunlight and rain tilt to improve the sunshade and rain protection effect.

[0025] Example 2

[0026] Please see Figures 1 to 3Based on Embodiment 1, in order to adjust the angle of the protective plate, the support plate 3 has a square plate structure. The surface of the support plate 3 has a perforation, and the surface of the perforation has an annular groove. The diameter of the annular groove is larger than the diameter of the perforation. The rotating ring 17 is limited in the annular groove. Two fixing plates 11 are fixed at the ends of the two support plates 3 that are far apart from each other. The fixing plates 11 have an annular plate structure. The surface of the fixing plates 11 has a plurality of limiting grooves 15 arranged in a circular array. The limiting grooves 15 at different positions correspond to different protection angles. When it is necessary to adjust the angle of the protective plate, the limiting plate 12 can be embedded into the corresponding limiting groove 15 according to the actual needs, thereby fixing the angle of the protective plate.

[0027] The center rod 10 has a cylindrical structure, and a rotating ring 17 is fixedly connected to the surface of the center rod 10. The rotating ring 17 is rotatably connected in the through hole. A rubber groove 16 is opened on the surface of the center rod 10. The rubber groove 16 is a cross-shaped groove, which provides a movement track for the sliding of the movable block 13. The movable block 13 is slidably connected to the surface of the rubber groove 16. The movable block 13 has a cross-shaped block structure, which ensures that the movable block 13 can move stably along the design direction when subjected to force, without shaking or deviation, and ensures the stability of the connection with the limiting plate 12 and the rubber column 14. The surface of the movable block 13 is fixedly connected to the rubber column 14, and the other end of the rubber column 14 is fixedly connected to the surface of the rubber groove 16. The limiting plate 12 is fixedly connected to the surface of the movable block 13. After the angle adjustment is completed, the rubber column 14 uses its own elastic restoring force to push the movable block 13, so that the limiting plate 12 automatically embeds into the limiting groove 15, thereby realizing the automatic locking of the angle of the center rod 10.

[0028] Example 3

[0029] Please see Figures 1 to 4 Based on Embodiment 2, in order to enable the protective plate to be telescopic and retractable, the outer ring surface of the limiting plate 12 is serrated. The serrated design greatly increases the friction and biting force between the limiting plate 12 and the limiting groove 15, making the limiting effect more solid and reliable. The outer ring surface of the limiting plate 12 is embedded in the limiting groove 15 to limit the center rod 10.

[0030] The first protective plate 4 has an arc-shaped structure. The arc shape can fit the outline of the recognition host 1 and camera 2, and can better cover and protect the equipment. The two ends of the first protective plate 4 have storage slots 6. The storage slots 6 are arc-shaped. The storage slots 6 can accommodate the second protective plate 5 when it is not necessary to expand the protection range, making the overall structure more compact and reducing the space occupied.

[0031] The first protective plate 4 has two sets of sliding grooves 7 on both sides, and each set of sliding grooves 7 is connected to the storage groove 6. The second protective plate 5 is slidably connected in the storage groove 6. The two ends of the second protective plate 5 are respectively fixedly connected with screws 8, which are slidably connected in the sliding grooves 7. Nuts are threaded onto the surface of the screws 8.

[0032] In actual use, when it is necessary to adjust the protection range of the protective plate, first tighten the nut on the surface of the screw 8 to pull the second protective plate 5 out of the storage slot 6. Adjust the extension length of the second protective plate 5 by sliding the screw 8 in the sliding slot 7. Then tighten the nut to fix the second protective plate 5 in the desired position, thereby increasing the protection range of the identification host 1. When a larger protection range is not required, the second protective plate 5 can be pushed back into the storage slot 6 for storage.

[0033] When the protective angle needs to be adjusted, first pull the two limiting plates 12 to the opposite ends. The limiting plates 12 drive the movable block 13 to slide along the inner wall of the rubber groove 16. The movable block 13 squeezes the rubber column 14 from its original state to a compressed state until the limiting plates 12 separate from the limiting grooves 15 on the surface of the fixed plate 11. Then rotate the limiting plates 12 to a suitable angle. The limiting plates 12 drive the center rod 10 and the adjusting plate 9 to rotate. After the adjusting plate 9 drives the first protective plate 4 to a suitable position, the two limiting plates 12 are then re-embedded into the limiting grooves 15 on the surface of the fixed plate 11.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
