Description

Technical Field

[0001] The utility model relates to the technical field of lenses, in particular to a lens with a protective cover. 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 the most important criterion 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.

[0003] A Chinese patent application CN219016779U discloses a lens with a protective cover. The key points of its technical solution are: by setting a rotating handle, the rotating rod rotates and drives the main bevel gear to rotate, the secondary bevel gear rotates and drives the bidirectional screw to rotate, so that the two screw sleeves drive the connecting block to produce displacement, and the connecting block is connected to the mounting shell so that the mounting shell drives the mounting block, thereby driving the upper protective cover and the lower protective cover to produce displacement closer to or away from each other. When the lens body is covered, stop rotating the handle so that the upper protective cover and the lower protective cover are firmly covered with the lens body, so that it can adapt to lens bodies of different calibers, thereby improving the practicality of the protective cover.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: different types of lenses need to be installed when the camera is in use, and a protective cover is installed on the lens surface when shooting is not needed to protect the lens. Since the traditional protective cover has a single function, the lens will still have the problem of dust absorption during actual use; therefore, a lens with a protective cover is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art, at least one technical problem raised in the background technology is solved.

[0006] The technical solution adopted by the utility model to solve its technical problems is as follows: a lens with a protective cover described in the utility model comprises a lens body and a protective device, the surface of the lens body is provided with a protective device, the protective device comprises a protective cover, the protective cover is sleeved on the surface of the lens body, the inner wall of the protective cover is rotatably connected with a rotating column, the surface of the rotating column is fixedly connected with a top ring, the inner wall of the rotating column is slidably connected with a pressure ring, and the pressure ring is located on the surface of the top ring. When the lens body is not needed, a cleaning cloth is attached to the top ring, and then the pressure ring is pushed to make the pressure ring slide on the inner wall of the rotating column, the pressure ring squeezes the cleaning cloth on the surface of the top ring, and then the protective cover is pushed to make the protective cover sleeved on the surface of the lens body, the cleaning cloth is attached to the lens body, and then the rotating column is rotated to make the rotating column drive the top ring and the pressure ring to rotate, the top ring drives the cleaning cloth to rotate, and the cleaning cloth rotates on the surface of the lens body. By setting the protective cover, the lens body can be protected, and at the same time, the rotating column, the top ring and the pressure ring can facilitate the cleaning of the lens body.

[0007] Preferably, two limit columns are fixedly connected to the surface of the pressure ring, and the surface of the limit columns is slidably connected to the inner wall of the top ring. The limit columns slide on the inner wall of the top ring. By setting the limit columns, the position of the pressure ring can be limited to reduce the situation of the pressure ring moving around.

[0008] Preferably, the surface of the pressure ring and the inner surface of the top ring are fixedly connected with a plurality of springs. When the pressure ring is released, the springs will rebound, and the springs will drive the pressure ring to slide.

By arranging the anti-slip ring and the anti-slip strips, the situation where the shield moves randomly on the surface of the mirror body can be reduced.

[0012] Preferably, two soft plugs are fixedly connected to the upper and lower ends of the card block, and a storage block is fixedly connected to the surface of the shield near the soft plug. The soft plug is arranged on the inner wall of the storage block, and the soft plug is inserted into the inner wall of the storage block. The position of the card block can be limited by setting the soft plug and the storage block.

[0013] Preferably, a storage groove is provided on the surface of the storage block, and the soft plug is inserted into the inner wall of the storage groove of the storage block. When the soft plug moves, the soft plug is inserted into the inner wall of the storage groove of the storage block. The opening of the storage groove can facilitate the storage of the soft plug.

[0014] The utility model is beneficial in that:

[0015] 1. When the mirror body is not in use, the utility model pulls the sliding column to make the sliding column drive the pressure ring to slide, and the pressure ring slides on the inner wall of the rotating column. When the pressure ring slides, it will drive the limit column to slide and drive the spring to contract. After the pressure ring slides to a suitable position, the cleaning cloth is wrapped around the surface of the top ring, and then the sliding column spring is released to rebound. The spring drives the pressure ring to slide, and the pressure ring fixes the cleaning cloth on the surface of the top ring. Then the protective cover is put on the surface of the mirror body. When the mirror body needs to be used, the turning handle is turned to make the turning handle drive the rotating column to rotate. When the rotating column rotates, it will also drive the limit plate to rotate. The limit plate rotates on the surface of the protective cover, and the rotating column drives the cleaning cloth on the top ring to rotate. The cleaning cloth rotates on the surface of the mirror body. By providing the protective cover, the mirror body can be protected, and the top ring and the pressure ring can facilitate the fixing of the cleaning cloth, thereby facilitating the cleaning of the mirror body.

[0016] 2. When installing the shield, the utility model aligns the card block on the anti-skid ring with the appropriate position on the surface of the shield, and then pushes the anti-skid ring to allow the anti-skid ring to drive the anti-skid strip and the card block to slide. The card block is inserted into the inner wall of the shield. When the card block slides, it will drive the soft plug to move. The soft plug is inserted into the inner wall of the storage block.
