Submerged camera

Abstract

The invention discloses a submerged camera. The submerged camera comprises a camera body and a sphere. The upper half part of the sphere is a solid upper hemisphere, and the lower half part is a hollow glass cover. The upper hemisphere is integrated with the glass cover. The camera body is fixed on a connecting rod. The connecting rod is fixed on the lower end of a mandrel, and the cable of the camera body successively runs upward and out of the connecting rod and the mandrel. The lower end of the mandrel is embedded into the upper hemisphere. The submerged camera further comprises two sets of gland parts. The gland parts are nested from outside to inside with a threaded steel sleeve, an elastic bushing and an elastic rubber sleeve in order. The outer wall of the threaded steel sleeve is provided with a tapered thread. The large end face of the threaded steel sleeve is provided with two grooves. The elastic bushing is a conical tube, and the outer wall closely fits the inner conical wall of the elastic bushing. The mandrel and the cable are clamped by two sets of gland parts respectively. The submerged camera provided by the invention has the advantages of good sealing and flexible adjustment of the pressure seal.

Description

technical field [0001] The invention belongs to the technical field of cameras, in particular to an underwater camera. Background technique [0002] When the camera is used in water, it must not only be sealed and waterproof, but also have a certain pressure-bearing capacity. Because the deeper the submerged water, the greater the pressure, the higher the sealing requirements, and the current camera not only does not have the pressure-bearing sealing performance The adjustment ability, and its own sealing and water resistance are unstable, easy to leak, especially the connection method with screw thread on the glass parts, not only the sealing is poor, but also the strength is low, and the thread teeth are easy to crack. Contents of the invention [0003] The object of the present invention is to provide a submerged camera head, which not only has good sealing performance, but also can freely adjust its pressure-bearing sealing ability according to different submerged dept...

Because the deeper the submerged water, the greater the pressure, the higher the sealing requirements, and the current camera not only does not have the pressure-bearing sealing performance The adjustment ability, and its own sealing and water resistance are unstable and easy to leak, especially the connection method of setting threads on the glass parts, which not only has poor sealing performance, but also has low strength, and the silk teeth are easy to crack
