Description

Technical Field

[0001] The utility model relates to the field of camera lens maintenance, in particular to a camera lens maintenance device. Background Art

[0002] The camera lens is the most important part of the camera, because its quality directly affects the quality of the image taken. At the same time, the lens is also one of the most important criteria for classifying camera types and grades. Generally speaking, cameras can be divided into three grades according to the lens: professional cameras, semi-professional cameras and ordinary cameras. Both traditional film cameras and digital cameras can be applied to this classification. Lenses can be divided into two categories: zoom and fixed focus.

[0003] After searching, a utility model patent with announcement number CN217846843U specifically discloses a camera lens protection device, including a camera lens housing, a lens is fixedly installed inside the camera lens housing, a lens protection cover is arranged on the outside of the camera lens housing, an external thread is arranged on the outside of the camera lens housing, an internal thread is arranged on the inside of the lens protection cover, and the external thread is matched with the internal thread, a rotating motor is fixedly installed inside the lens protection cover, a threaded rod is welded to the output shaft of the rotating motor, a first movable seat is threadedly connected to the surface of the threaded rod, a movable plate is fixedly installed on the side of the first movable seat, and a cleaning brush is fixedly installed on the bottom of the movable plate. As long as the protection device is installed on the outside of the camera lens, the lens can be cleaned at any time, and the outer surface of the lens protection cover is provided with a plastic base layer, the plastic base layer is made of ABS plastic, and the outer surface of the plastic base layer is provided with a nano coating, which greatly improves the protection effect of the protection device.

[0004] In the above patent, the lens surface is cleaned only by rotating the motor to drive the threaded rod to rotate and drive the cleaning brush. However, this left and right movement cannot ensure that the dust above the lens is effectively cleaned. The dust after cleaning still remains inside the protective cover, so that the dust is still likely to return to the lens surface. Once dust enters the inside of the lens, the above patent cannot fully solve the cleaning and maintenance of the lens. In addition, the size of the lens protective cover of the above patent is fixed and can only be installed for lenses of one size. If the lens sizes are large, devices of multiple sizes need to be prepared, which greatly increases the cost of use.

[0005] Therefore, it is necessary to invent a camera lens maintenance device to solve the above problems. Utility Model Content

By turning the knob 9, the screw 7 is driven to rotate and the internal threaded tube 6 is driven to drive the connecting block 5 to move up and down.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a control box 10 is installed on the side of the connecting block 5 away from the internal threaded tube 6, and an electric telescopic rod 11 is installed below the control box 10. A cleaning cotton disc 12 is rotatably connected below the electric telescopic rod 11, and a driving mechanism 13 is installed on the side of the electric telescopic rod 11. The driving mechanism 13 includes: two sets of gears and a set of motors. One set of gears is connected to the output end of the motor, and one set of gears is connected to the cleaning cotton disc 12 below. The two sets of gears are meshed. The motor is installed on the side of the electric telescopic rod 11. The motor drives the gears to rotate and drives the gears on the cleaning cotton disc 12 to rotate, thereby driving the cleaning cotton disc 12 to rotate as a whole. The cleaning cotton disc 12 is driven by the driving mechanism 13. The driving mechanism 13 can drive the cleaning cotton disc 12 to rotate, and the electric telescopic rod 11 can push the cleaning cotton disc 12 to move downward.

[0027] like Figure 1 , Figure 3 and Figure 5 As shown, a fixed cylinder 14 is installed above the dust box 1, and a lever 15 is connected to the inner wall of the fixed cylinder 14 through which a spring 16 is fitted and connected to the inner wall of the fixed cylinder 14. The spring 16 is sleeved with the lever 15, and a fixed plate 17 is fitted and connected to the spring 16 on the side away from the inner wall of the fixed cylinder 14. The fixed plate 17 is fixedly connected to the lever 15, and the lever 15 can drive the fixed plate 17 to move and squeeze the spring 16.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a protective cover 18 is fitted and connected to the side of the fixing plate 17, a cotton gasket 19 is fixedly connected to the inner wall of the protective cover 18, and a sealing gasket 20 is fitted and connected to the bottom of the protective cover 18. The cotton gasket 19 and the sealing gasket 20 can ensure the sealing between the bottom of the lens and the dust suction port 21.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a dust suction port 21 is installed above the dust suction box 1, the dust suction port 21 is connected with the dust suction box 1, the dust suction port 21 is sleeved with the sealing gasket 20, and the dust suction port 21 is sleeved inside the protective cover 18. The dust inside the lens can be cleaned through the dust suction port 21 and the dust suction box 1.

[0030] The working principle of the utility model is as follows: the lens is placed with the mirror surface facing upward inside the protective cover 18, and the driving mechanism 13 is turned on at this time, and the driving mechanism 13 drives the cleaning cotton disc 12 to rotate, and the surface of the cleaning cotton disc 12 is sprayed with a lens-specific cleaning agent, and the electric telescopic rod 11 drives the cleaning cotton disc 12 to move downward, so that the cleaning cotton disc 12 contacts the mirror surface of the lens to clean the surface dust, and at the same time, the dust collection box 1 below is started, and the dust inside the lens is sucked through the dust collection port 21 to extract the dust inside, and the cotton gasket 19 on the inner wall of the protective cover 18 is attached to the surrounding of the lens, and the sealing gasket 20 below ensures the sealing of the protective cover 18, so that the dust collection The port 21 forms a small negative pressure with the area below the lens, so that dust can be sucked out smoothly. When it is necessary to clean lenses of different sizes, the lever 15 can be pulled to drive the fixing plate 17 to squeeze the spring 16, so that the protective cover 18 can be taken out. At this time, a new protective cover 18 of suitable size is replaced, and the fixing plate 17 is re-fixed to the side of the new protective cover 18 by the spring 16. The knob 9 can be turned according to the length of the new lens to drive the screw 7 to rotate, so that the screw 7 drives the internal threaded barrel 6 to move, and the electric connecting block 5 of the internal threaded barrel 6 slides along the guide rod 4 inside the through groove 3 to raise the overall height of the control box 10, thereby ensuring that the new lens can be installed smoothly.

[0031] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
