Description

Technical Field

[0001] The present application relates to the technical field of camera lens production, and in particular to a lens focusing tool. Background Art

[0002] In the camera lens production process, it is an important step to test the focus of the camera lens that has just been produced and not assembled into a complete product. Focus testing usually requires the use of special focus test patterns or test tools, which help users accurately evaluate the focus accuracy of the camera lens.

[0003] The user needs to set the focus test card in the shooting direction of the camera lens. The focus test card is a card or board printed with patterns with high-contrast lines or marks, which is used to evaluate the focus accuracy of the camera lens. By shooting these patterns and observing which parts of the image are clear, you can judge whether the camera is focused correctly. After completing the focus test card setting, connect the camera lens through the test motherboard, use the camera control software or third-party software, which allows the user to remotely control the camera through a computer or mobile device, shoot focus test images, and evaluate the focus results on the computer screen.

[0004] When conducting the test, the user needs to hold the focus test card steadily with one hand and use the other hand to adjust the focal length of the camera lens so that the camera lens can focus and clearly capture the pattern on the focus test card. Therefore, the actual operation is not convenient enough and can easily lead to inaccurate test results.

[0005] Therefore, based on the above problems, the prior art needs to be improved. Utility Model Content

[0006] The purpose of this application is to improve the convenience and accuracy of camera lens focus testing.

[0007] The above technical purpose of the present application is achieved through the following technical solutions: a lens focusing tool, including a fitting, a hollow arrangement of the fitting to form an avoidance channel, a clamping part is provided on the inner wall of the avoidance channel for clamping the focus ring assembly of the camera lens, a cover body is provided on the fitting, the cover body is surrounded to form an accommodating cavity, the accommodating cavity and the avoidance channel are connected, an identification part is provided in the accommodating cavity, and the identification part is arranged corresponding to the avoidance channel.

[0008] By adopting the above technical solution, through the setting of the fitting, the tool can be adapted to the camera lens to ensure a stable connection. The avoidance channel formed by the hollow setting of the fitting can be connected by the clamping piece, so that the focus ring assembly of the camera lens can rotate freely, thereby adjusting the position of the lens in the camera lens, so that the camera lens can clearly capture the content on the identification piece in the cover body, which is convenient for users to test and observe the focus shooting effect of the lens. The fitting and the identification piece are integrated together through the cover body, and the user can complete the focus adjustment of the camera lens by rotating the cover body with one hand, and the lens can clearly capture the content on the identification piece, effectively improving the efficiency and accuracy of the focusing operation.

[0009] Optionally, there are multiple clamping parts.

[0010] By adopting the above technical solution, since there are multiple clamping parts, more contact points can be provided, and the contact area with the camera lens is increased, thereby enhancing the stability between the tool and the lens. This helps to ensure that the tool can be firmly fixed on the lens and is not easy to slide or loosen during the focusing operation. The stable connection can ensure that the relative position between the focusing tool and the lens remains stable without offset or shaking. This helps to maintain the accurate position of the focus ring assembly, thereby improving the accuracy and precision of the focusing operation. The stable connection can reduce vibration and shaking caused by looseness or instability between the tool and the lens. This makes the operation smoother during the focusing operation, and the focus can be adjusted more finely, reducing the possibility of misoperation.

[0011] Optionally, a plurality of the clamping members are evenly spaced apart.

[0012] By adopting the above technical solution, by setting the clamping parts at even intervals, it is possible to ensure that the contact force with the camera lens is evenly distributed. This helps to reduce excessive pressure on a single contact point and avoid local deformation or damage during the focusing process. The clamping parts set at even intervals can provide more stable support during connection, ensuring a more secure connection between the lens focusing tool and the camera lens. This helps to reduce looseness or displacement during use and improves the stability and reliability of the tool. The stable connection and evenly distributed force help to ensure that the relative position between the focusing tool and the camera lens remains stable. This can improve the accuracy of the focusing operation, allowing the user to adjust the focus more accurately and obtain a clearer image.

[0013] Optionally, the cover body is made of a light-transmitting material.

[0014] By adopting the above technical solution, the cover body made of translucent material can allow light to pass through, so that the pattern on the focus test card can still be observed when performing a focus test. This ensures that the propagation of light will not be affected during the test, thereby obtaining more accurate test results. The cover body serves as an external protective cover for the focusing tool, which can effectively protect the lens and identification parts from external contamination, scratches or damage during the test. The translucent material not only provides a protective function, but also ensures that the test is not affected while protecting the lens box identification parts.

[0015] Optionally, the engaging member and the cover body are detachably connected.

[0016] By adopting the above technical solution, since the fitting and the cover are detachably connected, users can easily separate them for easy cleaning and maintenance. This helps to keep the focusing tool clean and can promptly remove any dirt or impurities that may affect the focus test. The design of detachable connection enhances the flexibility of the focusing tool, and users can choose different models of fittings according to actual needs to adapt to test lenses of different specifications.

[0017] Optionally, a first mounting member is provided on the engaging member, the first mounting member is hollow to form an installation channel, the installation channel and the avoidance channel are connected, a second mounting member is extended to form on the cover body, the second mounting member is provided with an internal thread, and an external thread is provided on the inner wall of the installation channel, and the engaging member can be installed or removed from the cover body through the cooperation of the first mounting member and the second mounting member.

[0018] By adopting the above technical solution, through the threaded fit between the first mounting member and the second mounting member, the user can quickly install or remove the fitting and the cover, making the assembly and disassembly process of the entire focusing tool more convenient and efficient. The threaded fit can provide a stable and reliable connection, ensuring that the connection between the fitting and the cover is tight and firm without looseness or swinging, thereby improving the stability and reliability of the focusing tool. Since the installation and disassembly process is simple and quick, the user can easily perform maintenance and cleaning. This helps to keep the focusing tool clean and extend its service life. The threaded connection method has high durability and can withstand large torque and repeated use, so it can ensure the long-term and stable operation of the focusing tool.

[0019] Optionally, a marking piece is provided on the first mounting piece.

[0020] By adopting the above technical solution, the marking piece can help the user quickly and accurately locate the position of the first mounting piece. During the installation process, the user can easily find the correct installation point according to the position of the marking piece, thereby improving the efficiency and accuracy of the installation. At the same time, the marking piece can mark the corresponding size specifications of the embedded piece, which is convenient for the user to adapt the embedded piece and the camera lens for installation.

[0021] Optionally, the presence of the ridges can provide more gripping points, increasing the user's grip during installation. This allows the user to hold the first mounting piece more firmly, thereby performing the installation operation more stably. The design of the ridges can help the user accurately locate the position of the first mounting piece. By touching the ridges, the user can feel the edge and angle of the mounting piece, thereby more accurately controlling the position and direction of the installation and reducing installation deviations. The design of the ridges increases the roughness of the surface of the mounting piece, increases the friction between it and the user's hand, and thereby enhances the anti-slip property. This allows the user to control the mounting piece more stably and reduce operational errors caused by hand slippage.

[0022] In summary, this application has at least the following beneficial effects:

[0023] 1. Through the setting of the fitting, the tool can be adapted to the camera lens to ensure a stable connection. The avoidance channel formed by the hollow setting of the fitting can be connected through the clamping piece, so that the focus ring assembly of the camera lens can rotate freely, thereby adjusting the position of the lens in the camera lens, so that the camera lens can clearly capture the content on the identification piece in the cover, which is convenient for users to test and observe the focus shooting effect of the lens. The fitting and the identification piece are integrated together through the cover body, and the user can complete the focus adjustment of the camera lens by rotating the cover body with one hand, and the lens can clearly capture the content on the identification piece, effectively improving the efficiency and accuracy of the focusing operation.

[0024] 2. The cover made of transparent material allows light to pass through, so that the pattern on the focus test card can still be observed during the focus test. This ensures that the propagation of light will not be affected during the test, thereby obtaining more accurate test results. As an external protective cover for the focus tool, the cover can effectively protect the lens and identification parts from external contamination, scratches or damage during the test. The transparent material not only provides a protective function, but also ensures that the test is not affected while protecting the lens box identification parts.

[0025] 3. Through the threaded fit between the first mounting member and the second mounting member, the user can quickly install or remove the fitting and the cover, making the assembly and disassembly process of the entire focusing tool more convenient and efficient.
