Description

Technical Field

[0001] This utility model relates to the field of lens interface technology, and in particular to a lens interface device for quick replacement. Background Technology

[0002] In the field of optical equipment, the connection performance between the lens and the main body of the device directly affects image quality and user experience. As a core component of optical equipment (such as cameras, microscopes, and industrial cameras), the lens's quick and stable installation and removal are crucial for equipment maintenance, function switching, and multi-scenario applications. Frequent lens replacements can meet different shooting needs, equipment upgrades, or fault repairs, thus requiring efficient and reliable lens interface devices.

[0003] Currently, existing lens interface devices often present challenges in installation and disassembly due to difficulties in precise thread alignment and the lack of auxiliary positioning structures, resulting in complex and time-consuming operations. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art, such as the difficulty in accurately aligning the threads during installation and disassembly, the lack of auxiliary positioning structures, which leads to complicated and time-consuming operations, and poor sealing which can affect the clarity of the device. The invention proposes a lens interface device for quick replacement.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A quick-change lens interface device includes a lens body with a lens barrel spirally connected to it. The lens body has a T-shaped groove inside and a spring groove at its bottom, where a spring is installed. The spring applies a force to the lens body during disassembly and installation. A threaded groove is formed on the outer wall of the bottom of the lens body. An annular buckle is installed inside the lens body, its plane abutting against the spring. A T-shaped buckle is fixedly connected to the annular buckle, matching the T-shaped groove. A trapezoidal buckle is fixedly connected to the inner wall of the annular buckle. An adapter ring is installed on the annular buckle, with a trapezoidal groove at its upper end matching the trapezoidal buckle.

[0007] To ensure a more stable connection, preferably, a threaded groove is provided on the outer wall of the bottom of the lens body, and a threaded groove is provided inside the lens barrel, with the threaded groove being threadedly connected to the threaded groove.

[0008] To prevent dust and moisture from entering after installation, a sealing ring is preferably fitted onto the threaded top of the lens body.

[0009] To make rotation smoother and less strenuous during use, the lens body is preferably fixedly connected with an anti-slip key.

[0010] To make the structure more stable, preferably when the lens body is first installed in the lens barrel, the annular buckle and the adapter ring are used in conjunction with the lens body.

[0011] Compared with the prior art, this utility model provides a quick-change lens interface device with the following advantages: it enables quick engagement and disengagement, reduces installation steps, provides spring release force to assist separation during disassembly, ensures smooth operation, has a simple and stable structure, is easy to use, and prevents some dust and moisture from entering and damaging the equipment.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-7 A quick-change lens interface device includes a lens body 1, to which a lens barrel 2 is spirally connected. The lens body 1 is characterized by having a T-shaped groove 101 inside, a spring groove 102 at its bottom, a spring 103 installed within the spring groove 102, and the spring 103 applying a corresponding force to the lens body 1 during disassembly and installation. A threaded groove 104 is formed on the outer wall of the bottom of the lens body 1. An annular latch 4 is installed inside the lens body 1, its plane abutting against the spring 103. A T-shaped latch 401 is fixedly connected to the annular latch 4. T-shaped buckle 401 matches T-shaped groove 101. Trapezoidal buckle 402 is fixedly connected to the inner wall of ring buckle 4. Adapter ring 3 is installed on ring buckle 4. Trapezoidal groove 301 is opened at the upper end of adapter ring 3. Trapezoidal groove 301 matches trapezoidal buckle 402. Threaded groove 201 is opened inside lens barrel 2. Threaded groove 201 is threadedly connected to threaded groove 104. Sealing ring 5 is fitted on the top of thread of lens body 1. Anti-slip key 105 is fixedly connected to lens body 1. When lens body 1 is first installed in lens barrel 2, ring buckle 4 and adapter ring 3 are used in conjunction with lens body 1.

[0022] In this utility model, the mounting ring 3 is connected to the annular buckle 4 during use. When in use, the trapezoidal buckle 402 on the annular buckle 4 is first placed into the trapezoidal groove 301, and then rotated to lock it in the trapezoidal groove 301. Then, the T-shaped buckle 4 is aligned with the T-shaped groove 101 of the lens body 1 for installation, thus completing the connection between the mounting ring 3 and the lens body 1. The trapezoidal buckle 402, the trapezoidal groove 301, the T-shaped buckle 401 and the T-shaped groove 101 form a multi-level limiting system. First, the trapezoidal structure of the adapter ring 3 and the annular buckle 4 is used for quick pre-positioning, and then the displacement of the annular buckle 4 is limited by the T-shaped structure to ensure the connection accuracy.

[0023] Align the threaded groove 104 of the lens body 1 with the threaded groove 201 of the lens barrel 2, and then screw the lens body 1 together. Tighten the screw, and the threaded groove 104 and threaded groove 201 will screw together the lens body 1 and the lens barrel 2. The structure is simple and stable. During the process, the spring 103 is compressed, which effectively prevents thread misalignment. The spring 103 is installed in the spring groove 102 at the bottom of the lens body 1. When the lens body 1 and the lens barrel 2 are screwed together, as they rotate closer to each other, the spring 103 will be gradually compressed. During the compression process, the spring 103 will generate a spring force in the direction of the lens barrel 2. This spring force acts on the lens body 1, causing the lens body 1 to move towards the side of the lens barrel 2, allowing the lens to... During the initial rotational connection, the threaded groove 104 on the head body 1 and the threaded groove 201 on the lens barrel 2 align more quickly and accurately, assisting in the positioning process of the spiral connection between the two, making subsequent tightening and installation easier, and avoiding problems such as misalignment and inability to focus due to inaccurate thread alignment. During disassembly, rotating the lens body 1 in the opposite direction releases the spring 103 to assist in loosening the threaded connection. During installation, the spring is compressed and stored, and the spring force is used to assist the lens body 1 and lens barrel 2 to quickly align. During disassembly, the spring force is released to reduce the resistance to loosening the threads, making separation easier. The anti-slip key 105 installed on the lens body 1 allows the operator to hold it stably, achieving an anti-slip and labor-saving effect. The installed sealing ring 5 can maintain the sealing of the equipment during use.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
