The protective shell is then fitted onto the surface of the dome lens body. The transmission gear rotates in the opposite direction, causing the first and second racks to reset, moving the mounting block out of the mounting base and into the mounting hole. The retraction and removal of the mounting block from the mounting base facilitates quick assembly and disassembly of the protective shell from the dome lens body, improving the convenience of the protective shell.

Description

Technical Field

[0001] This utility model relates to the field of camera technology, and in particular to a double-layer sealed protective structure for a waterproof fog dome camera. Background Technology

[0002] A dome camera is a surveillance device with a hemispherical shape that integrates the lens and mounting bracket into one compact and aesthetically pleasing design. It can be seamlessly integrated into various scenarios. It typically uses a wide-angle lens to achieve wide-area monitoring and reduce blind spots. Its hemispherical shell not only has protective functions, being dustproof, waterproof, and vandal-proof, but can also conceal the direction of the lens to a certain extent, enhancing its concealment.

[0003] When using dome cameras, there is a problem with the lack of a protective housing for the lens. This significantly reduces the lens's protective effect, making it susceptible to dust, debris, and accidental impacts, affecting the quality of the monitoring image and the lifespan of the equipment. To solve this problem, a protective housing needs to be added to the lens. At the same time, considering the needs of daily maintenance, the protective housing should have a quick-replacement function. In this way, when the lens has a problem or needs cleaning and maintenance, the staff can quickly remove and install the protective housing to efficiently complete the maintenance work. This not only improves the lens's protective performance but also enhances the convenience of equipment maintenance, ensuring the stable operation of the dome camera.

[0004] Therefore, to address the above problems, a new double-layer sealed protective structure for a waterproof fog-proof dome camera is proposed. Utility Model Content

[0005] To overcome the problems existing in related technologies, this utility model provides a double-layer sealed protective structure for a waterproof fog dome camera. It can install a protective shell with a snap-fit ​​structure on the lens part, which is convenient for quick disassembly and assembly, and improves the convenience of lens maintenance. With the help of a sealing gasket, the lens part is provided with double-layer protection.

[0006] To achieve the above objectives, the first aspect of this utility model provides a double-layer sealed protective structure for a waterproof fog dome camera, comprising:

[0007] Support base body, dome lens body, protective shell, mounting base, mounting hole and mounting block;

[0008] The support body is rotatably connected to a hemispherical lens body. A protective shell is fitted onto the hemispherical lens body. A snap-fit ​​seat is symmetrically fixedly connected to the protective shell. Snap-fit ​​holes are symmetrically opened on the surface of the hemispherical lens body. Snap-fit ​​blocks that slidably engage with the snap-fit ​​holes are slidably installed inside the snap-fit ​​seats. A first rubber ring is fixedly connected to the inner wall of the protective shell. A second rubber ring is fixedly connected to the surface of the hemispherical lens body near the protective shell. Rectangular holes are symmetrically opened on the first rubber ring. Rectangular blocks that symmetrically engage with the rectangular holes are fixedly connected to the second rubber ring.

[0009] Furthermore, a drive block connected to the snap-fit ​​seat is provided on the side of the snap-fit ​​block away from the protective shell. A first rack is fixedly connected to the snap-fit ​​block, and a second rack is fixedly connected to the drive block. Both the first rack and the second rack are slidably connected to the inside of the snap-fit ​​seat. A transmission gear is rotatably connected inside the snap-fit ​​seat, and both the first rack and the second rack are meshed with the transmission gear.

[0010] Furthermore, guide blocks that are slidably connected to the inner wall of the snap-fit ​​seat are symmetrically fixed to the surfaces of both the snap-fit ​​block and the drive block, and springs that are fixedly connected to the inner wall of the snap-fit ​​seat are fixed to the guide blocks.

[0011] Furthermore, the snap-fit ​​block has a first anti-pressure hole that slides through the second rack, and the drive block has a second anti-pressure hole that slides through the first rack.

[0012] Furthermore, a first rubber ring is fixedly connected to the inner wall of the protective shell, and a second rubber ring is fixedly connected to the surface of the hemispherical lens body near the protective shell. Rectangular holes are symmetrically opened on the first rubber ring, and rectangular blocks that pass through the rectangular holes are symmetrically fixedly connected to the second rubber ring.

[0013] Furthermore, a sealing cover is bolted to the top of the support body, and a protective pad is provided between the support body and the sealing cover. The top of the support body and the bottom of the sealing cover are in contact with the surface of the protective pad. A first annular groove is provided at the top of the support body, and a second annular groove is provided at the bottom of the sealing cover. Annular blocks are fixedly connected to the upper and lower surfaces of the protective pad, and the annular blocks slide through the first and second annular grooves.

[0014] Furthermore, a conical ring is fixedly connected to one side of the protective pad. The conical ring is in contact with the surface of the support body and the sealing cover. The cross-section of the conical ring is triangular.

[0015] Furthermore, a partition strip is fixedly connected to the other side surface of the protective pad. The partition strip is in contact with the main body of the support base and the inner wall of the sealing cover. The partition strip is symmetrically provided with raised grooves.

[0016] The technical solution provided by this utility model can include the following beneficial effects:

[0017] In this example, by installing the mounting bracket, mounting hole, and mounting block, the protective shell is brought close to the dome lens body. Pressing the drive block causes the drive block to drive the second rack to contact the transmission gear. The transmission gear rotates, causing the first rack to move closer to the drive block, thus retracting the mounting block into the mounting bracket. The protective shell is then fitted onto the surface of the dome lens body. The transmission gear rotates in the opposite direction, causing the first and second racks to reset, thus removing the mounting block from the mounting bracket. The mounting block is then inserted into the mounting hole. By retracting and removing the mounting block from the mounting bracket, the protective shell can be quickly attached and detached from the dome lens body, improving the convenience of the protective shell.

[0018] In this example, by installing the first rubber ring and the second rubber ring, the protective shell is installed on the hemispherical lens body for initial protection. The first rubber ring is close to the second rubber ring, and the rectangular block enters the rectangular hole to quickly position the protective shell and the hemispherical lens body. The first rubber ring and the second rubber ring prevent impurities from entering from the gap between the protective shell and the hemispherical lens body, thus providing double protection for the hemispherical lens body.

[0019] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit the present invention. Attached Figure Description
