[0002] A camera is a video input device, a type of closed-circuit television, and is widely used in video conferencing, telemedicine, and real-time monitoring. Cameras generally have basic functions such as video recording, transmission, and still image capture. They capture images through a lens, and then the image is processed by the photosensitive components, circuitry, and control components inside the camera and converted into digital signals that can be recognized by a computer. The signals are then input into a computer via a parallel port or USB connection, and the software then reconstructs the image to form a picture.

[0003] Existing cameras can rotate and adjust their angles, but friction occurs in the rotating parts of the camera. This friction can cause the camera to age, thus reducing its lifespan. Utility Model Content

[0004] This utility model proposes a lubrication mechanism and a camera to overcome the shortcomings of existing technologies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a lubrication mechanism, comprising a bracket, the bracket being detachably mounted on a wall by means of bolts and providing overall support; a first turntable being rotatably connected inside the bracket; a first rotating shaft being fixedly connected to the top of the first turntable; a first motor being installed inside the bracket, wherein the first motor can drive the first turntable to rotate by means of a reducer; a second rotating shaft being fixedly connected to one end of the first rotating shaft; two second turntables being fixedly connected to both ends of the second rotating shaft; a U-shaped plate being disposed on the top of the bracket, wherein the two second turntables rotate inside the two arms of the U-shaped plate respectively; a second motor being installed on one side of the U-shaped plate, wherein the second motor can drive the second turntable to rotate by means of a reducer; and a lubrication device being disposed inside the U-shaped plate, wherein the lubrication device can lubricate the first and second turntables.

[0006] The effect achieved by the above components is as follows: when the camera rotates, the first motor inside the bracket is activated. The first motor drives the first turntable and the first shaft to rotate left and right with the help of the reducer. The second motor of the U-shaped plate is activated. The second motor drives the second turntable and the second shaft to rotate up and down with the help of the reducer, thereby completing the up, down and left and right rotation of the camera. At this time, the lubrication device lubricates the first turntable and the second turntable to avoid camera aging as much as possible.

[0007] Preferably, the lubrication device includes two cavities, which are respectively opened inside the two arms of the U-shaped plate. Oil inlets are opened at the corresponding cavities on the two arms of the U-shaped plate, and the oil inlets are interconnected with the interior of the cavities. Ball bearings are arranged inside the U-shaped plate, with one side of the ball bearings fitting against the second turntable and the other side located inside the cavity. A plurality of circular holes are opened on the arc surface of the second turntable, with the circular holes located above the second turntable. The reserved hole is opened inside the first turntable. The channel is opened inside the second turntable and the second rotating shaft, and the channel connects the reserved hole of the first turntable and the circular hole of the second turntable.

[0008] The effect achieved by the above components is as follows: Before the camera operates, the operator first sends lubricating oil into the cavity of the U-shaped plate through the oil inlet. When the second turntable rotates, it rotates relative to the ball bearings. The lubricating oil in the cavity enters the surface of the second turntable through the gaps in the ball bearings, lubricating the second turntable. Some of the lubricating oil enters the interior of the channel through the round hole of the second turntable. The lubricating oil in the channel flows into the reserved hole of the first turntable. Finally, the lubricating oil in the reserved hole flows to the arc surface of the first turntable. When the first turntable rotates, the lubricating oil on the arc surface of the first turntable achieves the effect of lubricating the first turntable. The lubrication device achieves the effect of lubricating both the first and second turntables simultaneously, minimizing friction between the first and second turntables and other components, thus preventing the first and second turntables from aging rapidly.

[0009] Preferably, a rubber plug is provided at the oil inlet of the U-shaped plate, wherein the size of the rubber plug is adapted to the size of the oil inlet.

[0010] The effect achieved by the above-mentioned components is that by blocking the oil inlet with a rubber plug, the lubricating oil in the cavity is protected, preventing the lubricating oil from flowing out of the oil inlet.

[0011] Preferably, a pull rope is fixedly connected to one side of the rubber plug, wherein one end of the pull rope is fixedly connected to the U-shaped plate.

[0012] The effect achieved by the above components is that by setting the pull rope, the maximum displacement of the rubber stopper is limited, thus preventing the rubber stopper from falling off when not in use.

[0013] Preferably, the cross-section of the channel is Y-shaped.

[0014] The effect achieved by the above components is that by setting up a "Y"-shaped channel, lubricating oil can easily enter the interior of the first turntable under its own gravity, thus facilitating the lubricating oil to lubricate the first turntable.

[0017] Preferably, the arc surface of the first turntable is provided with an annular groove, wherein the annular groove is inclined toward the inward direction of the first rotating shaft.

[0018] The effect achieved by the above components is that the circular grooves allow for the storage of lubricating oil, facilitating the lubrication of the first turntable.

[0019] A camera employing the aforementioned lubrication mechanism.

[0020] In summary, the beneficial effects of this utility model are as follows:

[0021] Before the camera operates, the staff first introduces lubricating oil into the cavity of the U-shaped plate through the oil inlet. When the second turntable rotates, it rotates relative to the ball bearings. The lubricating oil in the cavity enters the surface of the second turntable through the gaps in the ball bearings, lubricating the second turntable. Some of the lubricating oil enters the channel through the round hole of the second turntable, flowing into the reserved hole of the first turntable. Finally, the lubricating oil in the reserved hole flows onto the arc surface of the first turntable. When the first turntable rotates, the lubricating oil on the arc surface of the first turntable achieves the effect of lubricating the first turntable. The lubrication device achieves the effect of simultaneously lubricating the first and second turntables, minimizing friction between the first and second turntables and other components, thus preventing the first and second turntables from aging rapidly.

At this time, the lubrication device 9 lubricates the first turntable 2 and the second turntable 5 to avoid camera aging as much as possible.

[0030] Reference Figure 1-6As shown, the lubrication device 9 includes two cavities 91, which are respectively opened inside the two arms of the U-shaped plate 6. The two arms of the U-shaped plate 6 are provided with oil inlets 96 corresponding to the cavities 91, and the oil inlets 96 are connected to the interior of the cavities 91. The interior of the U-shaped plate 6 is provided with ball bearings 92, one side of which is in contact with the second turntable 5 and the other side is located inside the cavity 91. A number of circular holes 93 are opened on the arc surface of the second turntable 5, and the circular holes 93 are located above the second turntable 5. A reserved hole 95 is opened inside the first turntable 2. A channel 94 is opened inside the second turntable 5 and the second rotating shaft 4, and the channel 94 connects the reserved hole 95 of the first turntable 2 and the circular hole 93 of the second turntable 5. Before the camera operates, the staff first introduces lubricating oil into the cavity 91 of the U-shaped plate 6 through the oil inlet 96. When the second turntable 5 rotates, it rotates relative to the ball bearings 92. The lubricating oil in the cavity 91 enters the surface of the second turntable 5 through the gaps in the ball bearings 92, lubricating the second turntable 5. Some of the lubricating oil enters the interior of the channel 94 through the round hole 93 of the second turntable 5.
