Description

Technical Field

[0001] This utility model relates to the field of lens protection technology, and more specifically, to a lens protection device for photographic equipment. Background Technology

[0002] In the field of photography, especially with the use of camera lenses, lenses are susceptible to damage from impacts, dust, and oil, affecting image quality and equipment lifespan. With the popularization of photography and the increasing sophistication of equipment, protective devices have become crucial components for ensuring shooting quality and equipment safety. Traditional lens protection devices for photographic equipment are simple and practical to use, but lack versatility. For example, lens caps simply snap onto the front of the lens, secured by clips or rotation, which can block dust, fingerprints, and accidental impacts, but cannot prevent the lens from being dropped and falling to the ground due to a loss of balance, causing irreversible damage.

[0003] With the widespread use of lens protection devices, higher requirements have been placed on these devices. When using photographic equipment, more professional lenses are often replaced. These lenses are generally expensive and therefore require extra protection. In this case, a lens protection device can be installed on the outside of the lens to provide all-round protection for the lens, preventing damage from impacts, dust, etc., which could affect image quality and equipment lifespan. At the same time, the buffer device reduces potential energy and minimizes damage to the lens when it is dropped. Due to the all-round protection, lenses of certain shapes and styles need to have easy installation characteristics to achieve quick installation. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a lens protection device for photographic equipment, which further solves the problem of lens protection against lens damage.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A lens protection device for a photographic equipment includes a connecting ring. The surface of the connecting ring has multiple first mounting slots, each containing an expanding member. A protective shell is located on the top of each expanding member. A second mounting slot is located on the inner side of one end of the protective shell, and the expanding member is fixedly connected to the second mounting slot. Multiple third mounting slots are located at both ends of the protective shell, each containing a connecting rod. A drop-proof member is located on the outer side of each connecting rod. Two focusing holes are located between the aforementioned third mounting slots at both ends, and these focusing holes are positioned on the surface of the protective shell. A threaded ring is fixedly located at one end of the connecting ring, and a dust cover member is threadedly connected to the outer side of the threaded ring.

[0007] Preferably, the expansion member includes a first connector, which is fixedly connected to the first mounting groove.

[0008] Preferably, one end of the first connector is rotatably connected to the connecting plate, and the other end of the connecting plate is rotatably connected to the second connector, and the second connector is fixedly connected to the second mounting groove.

[0009] Preferably, the anti-fall component includes two telescopic slide rods, one end of each of the two telescopic slide rods is fixedly connected to a connecting rod, and a spring telescopic rod is provided between the telescopic slide rods.

[0010] Preferably, one end of the spring telescopic rod is fixedly connected to the connecting rod and is located in the middle of the connecting rod, and the other end of the telescopic slide rod is slidably connected to an anti-fall plate, which is fixedly connected to the other end of the spring telescopic rod.

[0011] Preferably, the dust cover component includes a dust cover ring, one end of which is fixedly provided with dustproof glass, and the other end of which is provided with a screw ring on its inner side.

[0012] This utility model has the following beneficial effects:

[0013] 1. Reduce lens drop damage: When designing lens protection devices for photographic equipment, the damage to the lens after it falls to the ground should be considered. Therefore, cushioning and shock absorption methods can be used to reduce lens drop damage. This can be achieved by converting gravitational potential energy into heat energy and using friction to reduce the instantaneous damage of gravitational potential energy to the lens. The shock-absorbing plate first contacts the ground, and then a spring telescopic rod is used for cushioning. At the same time, two telescopic sliding rods rotate and slide alternately to both sides, forming a triangular structure with the shock-absorbing plate. Because triangles have stability, the effect can be fully realized.

[0014] II. Comprehensive lens protection and quick installation: For comprehensive lens protection, the lens can be completely encased using four protective shells to prevent bumps or fingerprints. For specific lens models and shapes, the protective shells can be opened outwards. When the protective device is placed on the lens, the protective shells can be returned to their original positions and secured for quick installation.

[0015] 3. Dust prevention and reduced lens blur: By setting a dust cover, the lens glass can be prevented from being bumped, protecting the lens from cracks when taking pictures. It can also prevent dust, fingerprints, etc. from getting on the internal lens. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] As attached Figures 1 to 6 As shown, a lens protection device for a photographic equipment includes a connecting ring 1. The surface of the connecting ring 1 has multiple first mounting grooves 2. Each of the multiple first mounting grooves 2 has an expanding member 3 inside. The top of the expanding member 3 has a protective shell 4. A second mounting groove 5 is opened on the inner side of one end of the protective shell 4. The expanding member 3 is fixedly connected to the second mounting groove 5. Both ends of the protective shell 4 have multiple third mounting grooves 6. Each of the multiple third mounting grooves 6 has a connecting rod 7 fixedly installed inside. The outside of the connecting rod 7 has a drop-proof member 8. Two focusing holes 9 are provided between the aforementioned third mounting grooves 6 at both ends, and the focusing holes 9 are located on the surface of the protective shell 4. A threaded ring 10 is fixedly installed at one end of the connecting ring 1. A dust cover member 11 is threadedly connected to the outside of the threaded ring 10.

[0025] The connecting ring 1 is circular to accommodate the lens and facilitate installation. The connecting ring 1 also provides installation space, support, and a basic frame for the entire expansion component 3 and the shockproof component 8.

[0026] The connecting ring 1 is circular, and a threaded ring 10 is installed on one side of the connecting ring 1 to facilitate the installation of the dust cover component 11.

[0027] The design of the expansion component 3 is to allow the lens protection device to be installed on the lens conveniently, quickly and correctly. The first connector 31 and the second connector 33 in the expansion component 3 are basically the same size. The long rod of the first connector 31 for rotating the connecting plate 32 is opposite to the long rod of the second connector 33 for rotating the connecting plate 32, which allows the connecting plate 32 to rotate smoothly up and down, facilitating the expansion of the protective shell 4. The connecting plate 32 also fits perfectly into the reserved space inside the first connector 31 and the second connector 33, providing good space for closing and fixing the protective shell 4.

[0028] A protective shell 4 is added to the outer expansion component 3. The protective shell 4 is shaped with higher sides and a lower middle section. The higher sides allow it to contact the ground first, which is particularly important for the protective shell 4. The lower middle section serves two purposes: firstly, to hold the lens in place and secure the installation of the protective shell 4. By holding the lens in place while the protective shell 4 contacts the ground first, the lens position is stabilized. Secondly, the focusing hole 9 located at the lower part of the protective shell 4 facilitates lens focusing and also makes the protective shell 4 more securely attached.

[0029] The design of the protective shell 4 also provides space and a stable foundation for the installation of the anti-drop component 8. Due to the high sides and low middle of the protective shell 4, the anti-drop component 8 can be installed on the protective shell 4 to achieve the effect more effectively.

[0030] The two telescopic sliding rods 81, one spring telescopic rod 82, and the anti-drop plate 83 in the anti-drop component 8 form an anti-drop unit. Multiple anti-drop units form an octagonal structure, which can protect the lens 360°. The bottom ends of the two telescopic sliding rods 81 are rotatably connected to the connecting rod 7, while the top ends are fixed with sliders. At the same time, the initial position of the two telescopic rods should form a triangle with the anti-drop plate 83. Because the triangle is stable and has a certain angle, the slider at the top of the telescopic sliding rod 81 can slide smoothly on the anti-drop plate 83, generating friction to neutralize the gravitational potential energy during the fall and reduce lens damage.

[0031] The spring telescopic rod 82 is mainly a spring, with a telescopic rod fixedly sleeved on the outside. The two parts of the telescopic rod are also connected by a slider, which will also generate friction. Combined with the elasticity of the spring, it further neutralizes the gravitational potential energy of the fall and gives full play to the role of the anti-fall component 8.

[0032] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
