Description

Technical Field

[0001] The utility model relates to the technical field of photographic equipment, and particularly relates to a light-shielding cover for an advertising shooting camera. Background Art

[0002] A light-shielding cover is a device installed at the front end of a photographic lens, a digital camera, and a video camera to block harmful light, and it is also one of the most commonly used photographic accessories. Therefore, an existing light-shielding cover for an advertising shooting camera has been continuously innovated and developed. It can be seen that the current light-shielding cover for an advertising shooting camera basically meets people's needs, but there are still some problems.

[0003] For example, the patent document with the publication number CN217113017U discloses a light-shielding cover for a mirrorless camera, which "comprises a light-shielding cover body and a filter. One end of the light-shielding cover body is provided with a bayonet for connecting with a lens, and the second end of the light-shielding cover body is provided with a magnetic attraction part. The filter is installed at the second end position of the light-shielding cover body through the magnetic attraction part. By adopting the above technical solution, since there is a magnetic attraction part at one end of the light-shielding cover, the filter can be adsorbed on the magnetic attraction part, realizing the quick and simple installation of the filter, and avoiding the problem of the lens being bulky caused by an overly complex installation structure, and it is applicable to various lenses. It is convenient to disassemble, and at the same time, the functions of light shielding and filtering are realized."

[0004] However, when the above device is actually used, the light-shielding cover body is connected to the lens for use. Since the light-shielding cover body is relatively thin and the device has a bayonet opening for it, when it is subjected to external force, the light-shielding cover body is easily damaged, and the fragments of the light-shielding cover body are easily rubbed against or impact the lens, causing damage to the lens and reducing the practicability of the device. Therefore, there is an urgent need for a light-shielding cover for an advertising shooting camera to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a light-shielding cover for an advertising shooting camera to solve the problem of being easily damaged by external force as mentioned in the above background art.

[0006] To achieve the above purpose, the utility model provides the following technical solution. An advertising shooting camera light-shielding cover is disclosed, which includes a light-shielding cover body. The outer surface of the light-shielding cover body is threadedly connected with a fixing frame, and a sliding groove is opened on the outer surface of the fixing frame;

[0007] A first magnetic plate, the first magnetic plate is slidably connected to the inner wall of the sliding groove. A connecting frame is fixedly installed on the outer surface of the first magnetic plate. A first magnetic block is fixedly installed on the inner wall of the connecting frame. A protection plate is rotatably connected to the inner wall of the connecting frame. A second magnetic plate is fixedly installed on the inner wall of the sliding groove.

[0008] Preferably, an extension plate is slidably connected to the inner wall of the connecting frame, and a magnetic ring is arranged on the inner wall of the fixing frame.

[0009] Preferably, a second magnetic block is fitted and connected to the inner wall of the fixed frame, and the second magnetic block abuts against one side of the magnetic ring.

[0010] Preferably, a support frame is arranged on the inner wall of the second magnetic block, and a filter is arranged on the inner wall of the support frame.

[0011] Preferably, a baffle is rotatably connected to one side of the upper one of the two protection plates, and a sponge pad is arranged on one side of the baffle.

[0012] Preferably, a connecting block is arranged on one side of the extension plate, and the connecting block is fixedly connected to the outer surface of the second magnetic plate.

[0013] Preferably, there are two extension plates, and the opening of the extension plate is larger than the opening of the light-shielding cover body.

[0014] Preferably, the connecting frame is in a ring shape, and the inner wall diameter of the connecting frame is larger than the inner wall diameter of the fixed frame.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By driving the connecting frame to move backward, the first magnetic plate is driven to move backward, and then by using the mutual attraction between the first magnetic plate and the second magnetic plate, it is closely attached to the second magnetic plate, thereby fixing the first magnetic plate, and further stabilizing the protection plate. Moreover, the protection plate is transformed into a horizontal state, and the protection plate is unfolded, which is convenient for shooting. At this time, the protection plate can be used as a light-shielding cover, and the connecting frame and the extension plate can protect the light-shielding cover body, prevent it from being damaged, and extend the service life of the light-shielding cover body. When the first magnetic block is closely attached to the second magnetic block, the protection plate is transformed into a vertical state, sealing the light-shielding cover body, thereby protecting the lens, reducing the possibility of lens damage, and extending the service life of the lens.

[0017] 2. By inserting the second magnetic block into the fixed frame, and the mutual attraction between the second magnetic block and the magnetic ring can fix the second magnetic block and the fixed frame together, and further fix the filter and the light-shielding cover body together. The shooting quality is improved through the filter, and the fixed frame itself can reinforce the light-shielding cover body, reduce the possibility of damage to the light-shielding cover body caused by external forces, and extend the service life of the light-shielding cover body.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figure 1 , Figure 4 and Figure 5 A kind of embodiment provided by the present utility model:

[0026] It includes a light-shielding cover body 1, the outer surface of the light-shielding cover body 1 is threadedly connected with a fixing frame 2, a sliding groove 3 is opened on the outer surface of the fixing frame 2, a first magnetic plate 4 is slidably connected to the inner wall of the sliding groove 3, a connecting frame 5 is fixedly installed on the outer surface of the first magnetic plate 4, a first magnetic block 6 is fixedly installed on the inner wall of the connecting frame 5, a protection plate 7 is rotatably connected to the inner wall of the connecting frame 5, a second magnetic plate 8 is fixedly installed on the inner wall of the sliding groove 3, an extension plate 9 is slidably connected to the inner wall of the connecting frame 5, a connecting block 16 is arranged on one side of the extension plate 9, and the connecting block 16 is fixedly connected to the outer surface of the second magnetic plate 8. There are two extension plates 9, and the opening of the extension plate 9 is larger than the opening of the light-shielding cover body 1. The connecting frame 5 is in a ring shape, and the inner wall diameter of the connecting frame 5 is larger than the inner wall diameter of the fixing frame 2;

[0027] When using the light shield body 1, the fixed frame 2 is driven to rotate and connected to the light shield body 1. Then, the fixed frame 2 connects the connecting frame 5 to the light shield body 1 through the sliding groove 3 and the first magnetic plate 4. At this time, the protection plate 7 is lapped on one side of the fixed frame 2, which can seal the light shield body 1. When the device is not in use, the lens can be protected by the protection plate 7. When using the camera, the operator drives the connecting frame 5 to move backward, and the extension plate 9 slides into the connecting frame 5. Then, the connecting frame 5 drives the first magnetic plate 4 to move backward along the inner wall of the sliding groove 3. The first magnetic plate 4 gradually approaches the second magnetic plate 8, and the first magnetic plate 4 and the second magnetic plate 8 attract each other and are closely attached. At this time, the connecting frame 5 contacts the connecting block 16, thereby stabilizing the first magnetic plate 4, and further stabilizing the protection plate 7 through the connecting frame 5. At this time, the protection plate 7 unfolds, and the protection plate 7 can be used as a light shield.

[0028] Please refer to Figure 2 、 Figure 3 and Figure 4 , an embodiment provided by the present utility model:

[0029] A magnetic ring 10 is provided on the inner wall of the fixed frame 2. A second magnetic block 11 is fitted and connected to the inner wall of the fixed frame 2, and the second magnetic block 11 is lapped on one side of the magnetic ring 10. A support frame 12 is provided on the inner wall of the second magnetic block 11, and a filter 13 is provided on the inner wall of the support frame 12;

[0030] By driving the second magnetic block 11 and inserting it into the fixed frame 2, the second magnetic block 11 is fixed in the fixed frame 2 by the mutual attraction between the second magnetic block 11 and the magnetic ring 10. Then, the filter 13 is fixed on one side of the fixed frame 2 through the support frame 12, so that it is on the same axis as the light shield body 1. The shooting is carried out through the filter 13, and the light shield body 1 can be thickened through the fixed frame 2. When the light shield body 1 is subjected to an external force, the possibility of damage is reduced. The first magnetic block 6 and the second magnetic block 11 attract each other, thereby stabilizing the connecting frame 5 and further stabilizing the protection plate 7, ensuring the sealing performance of the protection plate 7. When the first magnetic block 6 is far from the second magnetic block 11 through the connecting frame 5 and the first magnetic plate 4 and the second magnetic plate 8 are closely attached, the first magnetic block 6 and the second magnetic block 11 are not in the same magnetic field. At this time, the first magnetic block 6 plays a role in supporting the connecting frame 5.

[0031] Furthermore, a baffle 14 is rotatably connected to one side of the upper of the two protection plates 7, and a sponge pad 15 is provided on one side of the baffle 14;

[0032] By rotating the baffle 14, and then the baffle 14 drives the protection plate 7 away from the lower part, so as to facilitate separating the two protection plates 7 for shooting.

[0033] Working principle: When using the hood body 1, first rotate and connect the fixed frame 2 to the outer surface of the hood body 1. At this time, the connecting frame 5 is connected to the hood body 1 through the fixed frame 2, and the protection plate 7 seals the hood body 1, thereby sealing and protecting the lens. When using the camera, the operator drives the first magnetic plate 4 to move backward along the inner wall of the chute 3 through the connecting frame 5. The first magnetic plate 4 gradually approaches the second magnetic plate 8. By using the mutual attraction between the first magnetic plate 4 and the second magnetic plate 8, the first magnetic plate 4 and the second magnetic plate 8 are closely attached, thereby stabilizing the first magnetic plate 4 and further ensuring the stability of the protection plate 7. At this time, the protection plate 7 is transformed from a vertical state to a horizontal state, and the protection plate 7 unfolds. At this time, the protection plate 7 can be used as a hood. In addition, by inserting the second magnetic block 11 into the fixed frame 2, the second magnetic block 11 can be fixed by the mutual attraction between the second magnetic block 11 and the magnetic ring 10, thereby completing the installation of the filter 13. The filter 13 improves the shooting quality and the practicability of the device. Moreover, the hood body 1 can be thickened through the fixed frame 2, reducing the possibility of damage caused by stress.
