However, these small cameras have relatively simple configurations, with only internal or external threads on the front of the lens for attaching filters or lens hoods, and the threaded connection makes operation cumbersome and time-consuming. Utility Model Content

[0003] To address the aforementioned problems in the existing technology, this utility model provides a small camera filter light-blocking system.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention discloses a small camera filter light-blocking system, comprising a connecting ring, a light-blocking cover, and a protective cover; wherein, the connecting ring contains a first filter lens, and one end of the connecting ring is used to connect to the front end of the lens of the small camera, and the other end is magnetically connected to the light-blocking cover and the protective cover in sequence.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0017] The present invention discloses a small camera filter light-blocking system, comprising a connecting ring 100, a light-blocking cover 200, and a protective cover 300; wherein, the connecting ring 100 has a first filter lens 101 inside, and one end of the connecting ring 100 is used to connect to the front end of the lens of the small camera, and the other end is magnetically connected to the light-blocking cover 200 and the protective cover 300 in sequence.

[0018] like Figure 1-3 As shown, the small camera filter light-blocking system of this utility model embodiment includes a connecting ring 100, which is used to connect to the front end of the lens of a small camera. Specifically, one end (rear end) of the connecting ring 100 is provided with a lens connecting part 104. The lens connecting part 104 can be an internal thread part or an external thread part that matches and connects to the front end of the lens, or it can be a clamping ring fitted on the front end of the lens. A first filter lens 101 is assembled inside the connecting ring 100. The first filter lens 101 is a UV filter, which not only filters ultraviolet rays but also protects the lens.

[0019] like Figure 1-5 As shown in the figure, the small camera filter light-blocking system of this utility model embodiment also includes a light-blocking cover 200, which is magnetically connected to the other end (front end) of the connecting ring 100. Specifically, the magnetic end (front end) of the connecting ring 100 is provided with a first magnetic member 102, and the magnetic end (rear end) of the light-blocking cover 200 is provided with a second magnetic member 201. Both the first magnetic member 102 and the second magnetic member 201 can be magnetic blocks. When the light-blocking cover 200 is aligned with the front end of the connecting ring 100, the first magnetic member 102 and the second magnetic member 201 are magnetically attracted to each other, so that the connecting ring 100 and the light-blocking cover 200 are magnetically fixed. The assembly is simple, convenient and quick.

[0020] Furthermore, both the first magnetic attractor 102 and the second magnetic attractor 201 are arranged in a ring. Specifically, there are two or more of each of the first magnetic attractor 102 and the second magnetic attractor 201, respectively embedded on the mutually magnetic end surfaces of the connecting ring 100 and the light shield 200. For example, there are five first magnetic attractors 102 and four second magnetic attractors 201, all of which are arc-shaped and arranged in a ring array. When the connecting ring 100 and the light shield 200 are magnetically attracted to their initial state (e.g., Figure 1When the lens hood 200 is magnetically connected to the connecting ring 100 (its top surface is horizontal), the first magnetic member 102 and the second magnetic member 201 form a circle. During use, the user can rotate and adjust the lens hood 200 according to shooting needs, so that the connecting ring 100 and the lens hood 200 rotate relative to each other. This process is flexible and convenient. Each first magnetic member 102 is magnetically connected to at least one second magnetic member 201, and each second magnetic member 201 is magnetically connected to at least one first magnetic member 102. While satisfying the need for rotational adjustment, the stability and reliability of the magnetic attraction between the connecting ring 100 and the lens hood 200 are ensured. This solves the problem that existing small cameras can only adjust the shading angle by rotating the camera after installing the lens hood (including inconvenience in operation and changes to the original composition).

[0021] Preferably, the lens hood 200 is a square lens hood with a lateral width greater than its longitudinal height, having a light-transmitting hole 203 in the middle and a rearwardly extending annular connecting portion 204, the end surface of which is embedded with a second magnetic member 201. After quickly assembling this square lens hood onto the lens of a small camera, it not only meets the light-blocking requirements but also significantly enhances the overall retro effect and perceived quality of the camera, making it more appealing to a wider range of consumers (especially young consumers such as students).

[0022] like Figure 1 , 5 As shown in Figure 6, the small camera filter light-blocking system of this embodiment also includes a protective cover 300. The light-blocking cover 200 and the protective cover 300 are magnetically connected to the other end (front end) of the connecting ring 100 in sequence. Specifically, the magnetically attracted ends of the light-blocking cover 200 and the protective cover 300 are respectively provided with a third magnetic member 202 and a fourth magnetic member 301. When the protective cover 300 is assembled onto the light-blocking cover 200, the third magnetic member 202 and the fourth magnetic member 301 are magnetically connected. For example, when the light shield 200 is a square light shield, a third magnetic member 202 is embedded in the inner circumferential surface of its front end. Correspondingly, the protective cover 300 is a square cover, and a fourth magnetic member 301 is embedded in its inner circumferential surface. When the protective cover 300 covers the front end of the light shield 200, the third magnetic member 202 and the fourth magnetic member 301 are magnetically attracted to each other, so that the protective cover 300 is magnetically fixed to the front end of the light shield 200.

[0023] For example Figure 1-3As shown in the figure, the front end of the connecting ring 100 of the small camera filter shading system of this utility model embodiment is provided with a filter connecting part 103. The user can assemble a filter with a second filter element into the front end of the connecting ring 100 and connect it to the filter connecting part 103 according to shooting needs. The filter connecting part 103 can be an internally threaded part, and the second filter element can be one of a star filter, polarizing filter, soft focus filter, or neutral density filter. This further enhances the functionality of the small camera filter shading system, meets more diverse shooting needs, and makes it more convenient to use.

[0024] Of course, the small camera filter light-blocking system of the present invention may also include a filter, which is detachably mounted in the front end of the connecting ring 100 and has the aforementioned second filter lens.

[0025] Furthermore, the miniature camera filter light-blocking system described in this invention can also be applied to photographic equipment and directly installed on the front of the lens of the photographic equipment.

[0026] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
