Problems solved by technology

[0002] The ambient temperature for normal use of existing cameras is mostly -30°C to 60°C, mainly because in a limited space, the waterproof structure of the camera is guaranteed by glue sealing, so the nominal use temperature of the glue determines the use environment of the camera , and then limit the camera can only meet the daily use conditions, but can not meet the use of complex and harsh environments

Embodiment 1

[0038] The video camera includes a barrel body composed of a front barrel assembly and a rear barrel assembly connected to provide a sealed machine cavity. The top of the fuselage is fixedly provided with a sunshield 13, which is not only waterproof and sun-proof, but also makes the overall appearance of the camera more attractive. Wherein: the front cylinder assembly includes the front cylinder 2 and the infrared transparent cover 9, the transparent cover assembly and the supplementary light element 7 arranged in the front cylinder 2 and axially from front to back, and the rear cylinder assembly includes the rear cylinder 10 and the rear cylinder 10. The lens assembly 6 in the barrel 10 , the lens assembly 6 includes a lens 61 . The lens assembly 6 and the supplementary light element 7 are arranged downstream of the transparent cover assembly.

[0039] In the present invention, "front" and "back" are determined according to the direction of the light, usually the light is fr...

Embodiment 2

[0058] Figure 8 The schematic camera includes a barrel body formed by connecting a front barrel assembly and a rear barrel assembly to provide a sealed machine cavity. The top of the fuselage is fixedly provided with a sunshade 13', which not only can prevent water and sun exposure, but also makes the overall appearance of the camera more attractive. Among them: the front tube assembly includes the front tube 2' and the infrared transparent cover 9' located in the middle 2' of the front tube 2' and axially from front to back, a transparent cover component and a supplementary light element, and the rear tube component includes the rear tube 10' and a lens assembly 6' disposed in the rear tube 10', the lens assembly 6' includes a lens. The lens assembly 6' and the supplementary light element 7' are arranged downstream of the transparent cover assembly.

Abstract

The invention discloses a camera. The camera comprises a front cylinder, a window body, and a lens body, wherein the installation surface of the front cylinder is provided with a second window through hole and a second light supplementing through hole; the window body is mounted in the second window through hole through a first sealing ring; and the lens body is mounted in the second light supplementing through hole through a second sealing ring. In the camera, a transparent cover assembly is installed on the installation face of the front cylinder in a sealed mode through the sealing ring, so that front end sealing can be provided for sealing of optical devices and electric devices on the downstream portion of the transparent cover assembly in the cylinder body; and as a sealing ring sealing mode is adopted, the waterproof performance of the camera can be guaranteed, and under the condition that the appearance size of the camera is not changed, the structural layout is compact, and space is saved, and meanwhile the risk of equipment water leakage caused by glue failure is reduced. As the front-end assembly of the whole camera is free of glue dispensing, and the whole sealing system adopts the sealing ring for sealing, and the lens is heated in the equipment, so that the camera can be suitable for various severe use environments.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video camera. Background technique [0002] The ambient temperature for normal use of existing cameras is mostly -30°C to 60°C, mainly because in a limited space, the waterproof structure of the camera is guaranteed by glue sealing, so the nominal use temperature of the glue determines the use environment of the camera , And then limit the camera can only meet the daily use conditions, but can not meet the use of complex and harsh environments. [0003] Therefore, a technical solution is desired to overcome or at least alleviate at least one of the above-mentioned disadvantages of the prior art. Contents of the invention [0004] It is an object of the present invention to provide a video camera that overcomes or at least alleviates at least one of the above-mentioned disadvantages of the prior art. [0005] To achieve the above object, the present invention provid...
