Description

Technical Field

[0001] The utility model relates to a camera device, in particular to a camera device used inside a hyperbaric oxygen chamber, belonging to the technical field of oxygen chamber structures. Background Art

[0002] In order to effectively monitor the situation inside the cabin in real time, the current hyperbaric oxygen chamber is generally equipped with a camera device. Because the interior of the oxygen chamber is a sealed pressure environment when in use, all facilities and components entering the cabin are required to have a certain pressure-bearing capacity, and the camera device is no exception. In order to meet the pressure resistance, the existing installation method of the camera device in the cabin is to encapsulate the camera and its connecting parts in a pressure-resistant container, and then directly fix the entire pressure-resistant container on the inner wall of the cabin. The problem with this camera device and its installation structure is that the entire device is large in size, occupies a large space inside the cabin, and is inconvenient to install and construct. At the same time, because the angle of the camera cannot be adjusted after the overall encapsulation, the monitoring angle of the camera device is limited. If you want to monitor and cover more cabin angles, you can only solve this problem by adding more camera devices, which not only increases costs, but also causes congestion in the cabin space.

[0003] In view of the above, there is an urgent need to provide a camera device that has a pressure-bearing effect, occupies a small space, and is easy to adjust the angle. Summary of the invention

[0004] The utility model aims to solve the above-mentioned technical problems and further provides an in-cabin camera device.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is:

[0006] An in-cabin camera device is arranged inside a hyperbaric oxygen chamber, comprising a through-cabin connection component and a camera main body structure, and its special features are:

[0007] The through-cabin connection assembly is used to fix the camera device on the cabin body and provide a through-cabin passage for the lines outside the cabin. Its structure includes an extension tube that penetrates and is sealedly connected to the through-cabin hole of the cabin body, a rotary joint connected to the extension tube, and a threaded joint connected below the rotary joint. The outer end of the extension tube is located outside the cabin, and the inner end is connected to the rotary joint inside the cabin. The through-cabin connection assembly is connected to the camera body structure via the threaded joint.

[0008] The camera main body structure is installed at the end of the cabin penetration connection component to provide a accommodating and packaging space for the camera. Its structure includes a camera tube seat, a camera placed in the camera tube seat, and a camera fixing cap threadedly screwed on the end of the camera tube seat to seal it. The end face of the camera fixing cap is designed as a plexiglass ball cover.

[0009] Furthermore, a fixing plate is welded on the outer periphery of the extension tube, and the fixing plate is fixed to the inner wall of the cabin by screws.

[0010] Furthermore, the rotary joint is assembled from a ball head and a ball seat that are adapted to each other. The top of the ball seat is fixedly connected to the extension tube via a threaded connection section, and the bottom of the ball seat is adapted and rotatably connected to the ball head via a ball groove. The ball groove and the ball head are rotated and sealed by rotating sealing connection surfaces that are pressed against each other.

[0011] Furthermore, the lower end of the ball head is connected to the upper thread section of the thread joint via an internal thread, and the lower thread section of the thread joint passes through the camera tube seat via a screw hole provided in the camera tube seat and is sealed therewith.

[0012] Furthermore, the fixing plate is welded to the outer periphery of the extension tube, and the fixing plate is fixed to the inner wall of the cabin via screws.

[0013] Furthermore, a sealing gasket is provided at the connection between the organic glass ball cover and the camera fixing cap.

[0014] Furthermore, a camera fixing plate is provided inside the camera tube holder, and the camera is mounted on the camera fixing plate.

[0015] Furthermore, a hard sealing gasket is provided between the camera fixing cap and the camera tube seat.

[0016] The utility model discloses an in-cabin camera device, which is assembled from two parts: a through-cabin connection component and a camera main body structure. Compared with the traditional structure in which the camera is directly packaged on the cabin wall, the utility model has a smaller size and a more practical structure. Not only can the through-cabin connection component be used to provide a pipeline channel for the camera main body structure, but the design of the rotary joint can also flexibly adjust the shooting angle of the camera main body structure. The camera is packaged through a pressure-resistant camera tube socket, and is combined with a plexiglass ball cover and its corresponding sealing structure to effectively improve the pressure-resistant protection performance of the camera.
