Description

Technical Field

[0001] This utility model relates to the technical field of lens barrel components, specifically a detachable camera calibration auxiliary lens barrel component. Background Technology

[0002] The detachable camera calibration auxiliary lens barrel assembly is a modular mechanical device used to assist in adjusting optical parameters and improving calibration accuracy during camera calibration. Its core function is to achieve flexible adaptation and stable optical path control through standardized interfaces and replaceable structures.

[0003] In existing lens barrel assemblies, a lens barrel cap is typically screwed to the front end of the lens barrel. To prevent the cap from being lost after being opened, a strap is usually used to connect the cap to the camera body. However, during camera use, the suspended cap is prone to shaking and impacting the user, and an excessively long strap can pull on the camera, resulting in a poor user experience and inconvenience. Therefore, we propose a detachable camera calibration auxiliary lens barrel assembly. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a detachable camera calibration auxiliary lens barrel assembly. This solves the problem that when using a lens barrel assembly, a lens barrel cap is usually screwed to the front end of the lens barrel. To prevent the lens barrel cap from being lost after being opened, a rope is usually used to connect the lens barrel cap and the camera body. However, when the camera is in use, the lens barrel cap is prone to shaking and hitting the user when it is suspended. In addition, if the rope is too long, it can easily pull and move the camera, resulting in a poor user experience.

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

[0006] A detachable camera calibration auxiliary lens barrel assembly includes a lens barrel body. A connecting ring is fixedly connected to one end of the lens barrel body, and the outer side of the connecting ring has an external thread. A fixing seat is symmetrically fixedly connected to one side of the lens barrel body. A rotating shaft is rotatably connected between the two fixing seats. A connecting seat is fixedly connected to the outer side of the rotating shaft. A lens barrel cover is fixedly connected to one side of the connecting seat. A sliding block is slidably connected to the inner wall of one of the fixing seats. A return spring is provided between the sliding block and the fixing seat. A limiting rod is fixedly connected to one side of the sliding block. A limiting ring is fixedly connected to the outer side of the rotating shaft. The limiting ring has equidistant limiting slots inside, which cooperate with the limiting rod. The sliding block drives the limiting rod to move into the limiting slot, thereby locking the position of the limiting ring and preventing the lens barrel cover from shaking during camera use.

[0007] Preferably, a limiting rod is fixedly connected to the inner wall of one of the fixed seats, and a limiting block is fixedly connected to one end of the limiting rod. The sliding block is slidably connected to the limiting rod. The movement of the sliding block can be limited by the setting of the limiting rod and the limiting block to prevent the sliding block from deviating when moving.

[0008] Preferably, a connecting rod is fixedly connected to one side of the sliding block at equal intervals. The connecting rod is slidably connected to the fixed seat, and the sliding block is moved by the connecting rod.

[0009] Preferably, a push block is fixedly connected to the end of the connecting rod away from the sliding block, and the push block drives the connecting rod to move.

[0010] Preferably, the outer side of the push block is fixedly connected with an anti-slip protrusion. The anti-slip protrusion can increase the friction and facilitate pushing the push block.

[0011] Preferably, there are six anti-slip protrusions, which are symmetrically distributed. The multiple sets of symmetrically arranged anti-slip protrusions can increase the friction, making it easier to push the push block to move.

[0012] This utility model provides a detachable camera calibration auxiliary lens barrel assembly. Compared with the prior art, it has the following advantages: This detachable camera calibration auxiliary lens barrel assembly, through the setting of a fixed base, push block, connecting rod, sliding block, return spring, limit rod, limit ring, limit slot, rotating shaft and connecting base, realizes the function of adjusting and locking the angle of the lens barrel cover during use. During the use of the camera, the lens barrel cover is not easy to shake, which will not affect the user, improve the camera user experience and facilitate use. Attached Figure Description

[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. 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.

[0021] Please see Figures 1 to 6 This utility model provides a technical solution:

[0022] A detachable camera calibration auxiliary lens barrel assembly includes a lens barrel body 1. A connecting ring 4 is fixedly connected to one end of the lens barrel body 1. The connecting ring 4 has external threads on its outer side. Fixing seats 3 are symmetrically fixedly connected to one side of the lens barrel body 1. A rotating shaft 6 is rotatably connected between the two fixing seats 3. A connecting seat 5 is fixedly connected to the outer side of the rotating shaft 6. A lens barrel cover 2 is fixedly connected to one side of the connecting seat 5. A sliding block 9 is slidably connected to the inner wall of one of the fixing seats 3. A return spring 10 is provided between the sliding block 9 and the fixing seat 3. A limit rod 14 is fixedly connected to one side of the sliding block 9. A limit rod 14 is fixedly connected to the outer side of the rotating shaft 6. The limiting ring 8 has equidistant limiting slots 13 inside, which cooperate with the limiting rod 14. The lens barrel body 1 can be quickly installed through the external thread on the outside of the connecting ring 4. The setting of the reset spring 10 can drive the sliding block 9 to move and reset. The sliding block 9 drives the limiting rod 14 to move into the limiting slot 13, thereby locking the position of the limiting ring 8 and preventing the rotating shaft 6 from rotating. This locks the position of the lens barrel cover 2, making it less likely for the lens barrel cover 2 to shake during camera use, which will not affect the user and improve the camera's user experience.

[0023] Furthermore, a limiting rod 11 is fixedly connected to the inner wall of one of the fixed seats 3, and a limiting block 12 is fixedly connected to one end of the limiting rod 11. The sliding block 9 is slidably connected to the limiting rod 11. The movement of the sliding block 9 can be limited by the setting of the limiting rod 11 and the limiting block 12 to prevent the sliding block 9 from deviating when moving.

[0024] Furthermore, a connecting rod 16 is fixedly connected at equal intervals to one side of the sliding block 9. The connecting rod 16 is slidably connected to the fixed base 3, and the sliding block 9 is moved by the connecting rod 16.

[0025] Furthermore, a push block 7 is fixedly connected to the end of the connecting rod 16 away from the sliding block 9, and the connecting rod 16 is moved by the push block 7.

[0026] Furthermore, an anti-slip protrusion 15 is fixedly connected to the outer side of the push block 7. The anti-slip protrusion 15 can increase the friction force, making it easier to push the push block 7.

[0027] Furthermore, there are six anti-slip protrusions 15 in total, which are symmetrically distributed. The multiple sets of symmetrically arranged anti-slip protrusions 15 can increase the friction, making it easier to push the push block 7 to move.

[0028] Working principle:

[0029] In use, the lens barrel body 1 can be quickly installed through the external thread on the outside of the connecting ring 4. When the lens barrel cover 2 needs to be opened for use, push the push block 7. The push block 7 drives the sliding block 9 to move through the connecting rod 16. The return spring 10 is compressed. The movement of the sliding block 9 can be limited by the setting of the limit rod 11 and the limit block 12. The sliding block 9 drives the limit insertion rod 14 to move and disengage from the limit slot 13, so that the lens barrel cover 2 can be rotated, causing the lens barrel cover 2 to rotate around the rotating shaft 6. After the lens barrel cover 2 is turned open, release the push block 7. The return spring 10 drives the sliding block 9 to move and reset due to the elasticity. The sliding block 9 drives the limit insertion rod 14 to move into the corresponding limit slot 13, thereby locking the position of the limit ring 8 and preventing the rotating shaft 6 from rotating. This locks the position of the lens barrel cover 2. During the use of the camera, the lens barrel cover 2 is not easy to shake, which will not affect the user and improve the user experience of the camera, making it easy to use.
