A flameproof camera with damping installation

Abstract

The invention discloses a flame-proof camera with damping installation, which comprises a glass dome in the shape of a hemispherical shell, an inner installation tube, and a circular tube-shaped outer installation tube; the inner installation tube includes a cylinder and a flange plate; the camera body is fixed On the inner wall of the cylinder; there is a flameproof gasket between the flange plate and the extension; the other end of the cylinder is screwed into the outer installation cylinder, and the cable of the camera body passes through the screw plug. The clamping tube is fixed at the end of the connecting rod, and one end of the clamping tube is fixed on the connecting rod. The support connected to the camera body is a T-shaped steel structure. The camera body is fixed on the stud of the horizontal steel plate of the support through a threaded sleeve; the mandrel The two ends of the shaft are respectively provided with threads, the first shaft section is screwed into the threaded hole of the clamping pipe, the threaded part of the second shaft section is screwed with an adjusting nut, and the mandrel between the adjusting nut and the pressure plate is sleeved with a compressed spring. The explosion-proof camera with damping installation is simple and reliable in structure, has good explosion-proof effect, and can keep stable without shaking when the position is adjusted.

Description

technical field [0001] The invention belongs to the technical field of cameras, in particular to an explosion-proof barrier camera. Background technique [0002] In the monitoring of flammable and explosive environments such as coal mines and flour mills, explosion-proof cameras are usually used. However, the current explosion-proof cameras either have complex structures, or are installed directly on the glass parts of the camera, such as hemispherical or spherical glass. Screw thread, because the glass itself is fragile, even tempered glass, the strength will be reduced after tapping, and the bigger defect is that it is difficult for the screw thread on the glass to have a good flameproof effect. On the other hand, in order to facilitate the flexible adjustment of the camera angle, the current camera is often installed with a universal flexible shaft connection, and the universal flexible shaft connection supports the camera has a limitation, that is, the flexibility of the...

[0002] In the monitoring of flammable and explosive environments such as coal mines and flour mills, explosion-proof cameras are usually used. However, the current explosion-proof cameras either have complex structures, or are installed directly on the glass parts of the camera, such as hemispherical or spherical glass. Screw thread, because the glass itself is fragile, even tempered glass, the strength will be reduced after tapping, and the bigger defect is that it is difficult for the screw thread on the glass to have a good explosion-proof effect

On the other hand, in order to facilitate the flexible adjustment of the camera angle, the current camera is often installed with a universal flexible shaft connection, and the universal flexible shaft connection supports the camera has a limitation, that is, the flexibility of the flexible shaft is certain. If it is soft, it is easy to shake the camera, causing the shooting picture to be shaken and unclear; for the hard flexible shaft, it needs to be twisted and adjusted manually, and it is difficult to adjust it quickly when the force is large, and some cameras For example, cameras in some factories are usually installed on the equipment casing or on the wall. In view of the use environment, flexible shafts with different softness are often replaced to meet the needs of cameras with different weights and different installation stability. At present, there is no camera that can flexibly and stably adjust the installation position
