Detailed Description

The utility model will be further elucidated and described with reference to the embodiments and drawings of the specification:

referring to fig. 1 to 10, a lens cap assembly includes a lens holder assembly 10, a rear cap 20 and at least two lens stoppers 30, the rear cap 20 is mounted on the lens holder assembly 10, the lens stoppers 30 are located between the lens cap assembly 10 and the rear cap 20 and movably connected to the lens holder assembly 10, a view finding hole is formed in the lens holder assembly 10, a lens mounting hole 21 corresponding to the view finding hole is formed in the rear cap 20, the view finding hole and the lens mounting hole 21 are through holes, and a screw fixing hole 22 is formed in the rear cap 20.

The lens holder assembly 10 includes a lens holder 11 and an outer ring 12 sleeved on the lens holder 11, the view finding hole 111 is located at the center of the lens holder 11, the lens barrier 30 includes a connecting portion 31 and a shielding portion 32, and the connecting portion 31 is slidably connected with the lens holder 11; one side of the connecting part 31 far away from the shielding part and the inner side of the outer ring 12 are both in a sawtooth shape, the connecting part 31 is connected with the outer ring 12 through the two gears 40, the gears 40 are respectively meshed with the connecting part 31 and the outer ring 12, and the gears 40 are positioned between the lens holder 11 and the rear cover 20.

After the shooting is finished, the outer ring 12 can be rotated, the two connecting parts 31 are close to each other along the lens holder 1, when the shielding part 32 is aligned with the view finding hole 111, the view finding hole 111 is closed, the shielding part 32 of the lens baffle 30 plays a role in protecting the lens, when the shooting is needed, the outer ring 12 is rotated in the reverse direction, the two connecting parts 31 are far away from each other along the lens holder 11, and when the shielding part 32 of the lens baffle 30 is moved out of the view finding hole 111, the view finding hole 111 is opened; therefore, the user of the camera can open and close the view finding hole 111 only by rotating the outer ring 12 in the forward and reverse directions without taking down or covering the lens cover from the lens, thereby bringing convenience to the user of the camera.

Two strip-shaped protrusions 112 are arranged on the lens holder 11 in parallel side by side, the two protrusions 112 are symmetrically located on two sides of the viewing hole 111, a groove 311 corresponding to the protrusions is formed in one side of the connecting portion 31, and the two protrusions 112 are located in the two grooves 311 respectively. The outer ring 12 drives the connecting portion 31 to slide along the protrusion 112, and the connecting portion 31 slides along the protrusion 112 under the limiting action of the protrusion 112, so that the moving direction of the connecting portion 31 is not deviated.

When the outer ring 12 is rotated, the two connecting portions 31 are respectively driven by the two gears 40 to move along the protrusions 112 in a direction toward or away from each other.

The center of the gear 40 is provided with a mounting hole 41, one side of the lens holder 11 close to the lens barrier 30 is provided with a positioning column 113, and the gear 40 is sleeved on the positioning column 113 through the mounting hole 41. When the rotating outer ring 12 rotates, the gear 40 rotates around the positioning column 113, so that the positioning column 113 can enable the gear 40 to rotate more stably.

The lens holder 11 is provided with four connecting posts 114 on one side close to the lens barrier 30, the four connecting posts 114 are uniformly distributed around the viewing hole 111, and the rear cover 20 is located in the outer ring 12 and is connected with the four connecting posts 114 through the four screws 50. So that a mounting space for the lens barrier 30 is formed between the rear cover 20 and the lens holder 11.

Four connecting posts 114 are respectively located at both ends of the two protrusions 112 and connected to the protrusions 112. The protrusion 112 simultaneously plays a role of reinforcing ribs for the four connecting columns 114, and the four connecting columns 114 can also play a role of limiting the movement of the connecting part 31 on the protrusion 112, so that the connecting part 31 is prevented from moving over and interfering with the inner side of the outer ring 12.

The viewing hole 111 is circular, the two shielding portions 32 are semicircular, and the two shielding portions 32 are overlapped with the viewing hole 111 when being closed together.
