Description

Technical Field

[0001] This utility model relates to the field of lens barrel linkage ring technology, and in particular to a floating lens barrel linkage ring assembly. Background Technology

[0002] The lens barrel linkage ring, also known as the adapter ring, was developed for some older camera models to connect to later-produced lens barrels and overcome interface incompatibility issues. This adapter ring structure allows photography enthusiasts to experience the use of different lenses more extensively and saves photography costs to some extent.

[0003] However, the traditional floating lens barrel linkage ring assembly has a simple snap-fit ​​installation structure. With repeated use, the connection between the linkage ring and the lens / camera can easily become loose, affecting the focusing process of the lens and causing a deterioration in shooting results.

[0004] For example, some traditional cameras use EF mount lenses, which cannot be used with many RF mount lenses. A connecting ring is designed to adapt the mount, allowing RF mount lenses to be mounted on EF mount cameras. However, when replacing different lenses, the adapter tube needs to be frequently disassembled and reassembled, which can easily cause wear and fatigue at the mount. The originally tight connection can easily become loose, resulting in a deterioration in lens image quality. Utility Model Content

[0005] This utility model discloses a floating lens barrel linkage ring assembly, which aims to solve the technical problem that traditional floating lens barrel linkage ring assemblies have a simple snap-fit ​​installation structure, but with repeated use, the connection between the linkage ring and the lens / camera is prone to loosening, affecting the focusing process of the lens and causing a deterioration in shooting effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A floating lens barrel linkage ring assembly includes a housing and a first mounting base and a second mounting base mounted at both ends of the housing. The side closer to the first mounting base is an EF interface end, and the side closer to the second mounting base is an RF interface end. Both the EF interface end and the RF interface end are provided with auxiliary limiting mechanisms. The auxiliary limiting mechanisms include a first buckle and a second buckle disposed on the first mounting base and the second mounting base. The inner opening of the first buckle is provided with a plurality of anti-slip protrusions distributed at equal intervals. The outer wall of one side of the second mounting base is provided with support pads distributed at equal intervals. The support pads are staggered with the second buckle.

[0008] By adopting the above technical solution, the anti-slip protrusions on the first buckle ensure that the EF interface end is anti-slip and supported when connected to the camera. Even with frequent and long-term disassembly and assembly, it can extend the service life to the maximum extent and ensure connection stability. The support pads that are alternately set with the second buckle can provide a buffer support effect after the RF interface end is connected to the lens, avoiding direct hard contact between the lens end and the RF interface end, reducing wear. At the same time, the support pads can also provide a reverse support effect, improving installation stability and ensuring that the lens can still produce clear images after being installed through the linkage ring.

[0009] As a further embodiment of this utility model: both ends of the outer shell are provided with ring gaskets, and the ring gaskets are located on the outside of the first mounting base and the second mounting base.

[0010] By adopting the above technical solution, the ring gasket can be tightly pressed against the connection between the linkage ring and the camera and lens, preventing external dust and moisture from entering and affecting the stable use of the lens.

[0011] In summary, this application includes at least one of the following beneficial technical effects:

[0012] 1. The connection process is tight. Unlike traditional snap-fit ​​structures, the first and second snap-fits in this solution are equipped with anti-slip protrusions and support pads, respectively, to ensure a tight connection between the linkage ring and the camera itself as well as with the lens, while reducing wear and tear during disassembly and assembly, and ensuring normal use.

[0013] 2. Excellent protection: The ring gaskets provide auxiliary support when the linkage ring is installed with the camera and lens, which not only improves the tightness of the connection, but also seals the connection to prevent external dust and water mist from interfering with the use of the lens.

[0014] Other features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0021] 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.

[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A floating lens barrel linkage ring assembly includes a housing 1 and a first mounting seat 4 and a second mounting seat 9 installed at both ends of the housing 1. The side closer to the first mounting seat 4 is the EF interface end 3, and the side closer to the second mounting seat 9 is the RF interface end 8. Both the EF interface end 3 and the RF interface end 8 are provided with auxiliary limiting mechanisms.

[0023] The auxiliary limiting mechanism includes a first buckle 5 and a second buckle 10 disposed on the first mounting base 4 and the second mounting base 9. The inner opening of the first buckle 5 is provided with a number of anti-slip protrusions 12 distributed at equal intervals. The outer wall of one side of the second mounting base 9 is provided with support pads 13 distributed at equal intervals. The support pads 13 and the second buckle 10 are staggered.

[0024] Specifically, the anti-slip protrusions 12 on the first clip 5 ensure that the EF interface end 3 is anti-slip and supported when connected to the camera. Even with frequent and long-term disassembly and assembly, the service life can be extended to the maximum extent and the connection can be guaranteed to be stable. The support pads 13, which are alternately arranged with the second clip 10, can play a buffer support role after the RF interface end 8 is connected to the lens, avoiding direct hard contact between the lens end and the RF interface end 8, reducing wear. At the same time, the support pads 13 can also play a reverse support role, improving the installation stability and ensuring that the lens can also form clear images after being installed through the linkage ring.

[0025] The thickness of each first buckle 5 varies in a gradient, and several anti-slip protrusions 12 are distributed on the thicker side of the first buckle 5. The anti-slip protrusions 12 are made of rubber. With the support of the rubber material, they can provide elastic cushioning and protect the camera connection end with their softness.

[0026] It should be noted that the support pad 13 is made of high-density sponge, which provides support while also offering elastic cushioning, making it convenient to use with the second clip 10 to connect the lens.

[0027] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, the first mounting base 4 is further provided with a plurality of first contacts 6, and the second mounting base 9 is further provided with a plurality of second contacts 11.

[0028] By setting the first contact 6 and the second contact 11, it can be ensured that after the switch is made, the camera on one side of the linkage ring can still control the lens.

[0029] It should be noted that a control ring 2 is provided on the outer wall of the outer shell 1. The control ring 2 can be used to control the parameters used by the camera. Specifically, the function assignment can be customized to adapt to the needs of different shooting scenarios.

[0030] Reference Figure 1 and Figure 2 In a preferred embodiment, both ends of the housing 1 are provided with ring gaskets 7, which are located outside the first mounting base 4 and the second mounting base 9.

[0031] The ring pad 7 is made of the same material as the support pad 13, and both the ring pad 7 and the support pad 13 are detachable structures.

[0032] It should be noted that the detachable structure of the support pad 13 and the ring pad 7 is specifically connected by adhesive. When the support pad 13 and the ring pad 7 are severely worn, they can be replaced to ensure that the linkage ring can continue to be used stably.

[0033] Specifically, the ring pad 7 ensures that the linkage ring is tightly pressed against the connection point of the camera and lens, preventing external dust and moisture from entering and affecting the stable use of the lens.

[0034] Working principle: When in use, first install the EF interface end 3 on one side of the linkage ring onto the camera. During the installation process, the first clip 5 will rotate and connect with the interface on the camera. After rotation, the anti-slip protrusion 12 on the first clip 5 will press and lock tightly against the interface on the camera to ensure a tight connection. Then start installing the lens. When connecting the second clip 10 to one end of the lens, the support pad 13 will cooperate to support and press tightly, and at the same time, the ring pad 7 will seal the connection to prevent external dust from penetrating.

[0035] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
