[0001] This utility model relates to the field of lens barrel structure technology, and in particular to a lens barrel structure with a detachable function. Background Technology
[0002] In industrial production, real-time monitoring of the production process is required, which necessitates the use of industrial cameras. The front end of an industrial camera typically needs to be equipped with a lens barrel structure to assist in imaging and enable its normal operation.
[0003] In practical applications, the existing lens barrel structure is relatively complete in structure and function, and can basically meet the needs of daily use. However, the following problems still exist:
[0004] In actual use, industrial production processes may result in the splashing of debris, which can land on the outer surface of the lens barrel, causing scratches and, in severe cases, cracking and damage to the outer surface, which is very inconvenient.
[0005] Therefore, this utility model provides a lens barrel structure with a detachable function. Utility Model Content

[0008] In a preferred embodiment, the frame is cubic in shape, and circular insert frames are fixedly connected to all four sides of the frame. One end of the circular insert rod is inserted into the inner wall of the circular insert frame, and a threaded clamp rod is fixedly connected to one end of the outer surface of the circular insert rod. A fixing nut is threadedly connected to one end of the outer surface of the threaded clamp rod. The outer diameter of the threaded clamp rod is smaller than the inner diameter of the circular insert frame, and the outer diameter of the fixing nut is larger than the inner diameter of the circular insert frame. Four rectangular connecting blocks are fixedly connected to the outer surface of the lens barrel and are arranged circumferentially along the direction of the lens barrel. A semi-circular support frame is fixedly connected to the top of the outer surface of the rectangular connecting blocks, and the outer surface of the circular insert rod overlaps with the semi-circular support frame.
[0009] The technical effect of adopting the above-mentioned further solution is that, under the action of the threaded clamp and the fixing nut, the round insert rod and the round insert frame can be auxiliaryly fixed, thereby enabling the protective net to be auxiliaryly fixed and enabling the protective net to provide auxiliary protection for the lens barrel.
[0010] In a preferred embodiment, an annular block is fixedly connected to the inner wall of the lens barrel, an N-pole magnet is fixedly connected to the inner wall of the annular block, an auxiliary ring plate is fixedly connected to one side of the outer surface of the funnel frame, and an S-pole magnet is fixedly connected to the inner wall of one side of the auxiliary ring plate.
[0011] The technical effect of adopting the above-mentioned further solution is that, under the action of the N-pole magnet and the S-pole magnet, the funnel frame can be fixed in an auxiliary manner, thereby providing auxiliary protection for the lens barrel without affecting its use.
[0012] In a preferred embodiment, a snap-fit ring frame is fixedly connected to one side of the outer surface of the funnel frame.
[0013] The technical effect of adopting the above-mentioned further solution is that the snap-fit ring frame can provide auxiliary dust protection at the connection between the funnel frame and the lens barrel.
[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0015] By setting up a detachable protective structure, the protective net can be disassembled and assembled, thereby providing auxiliary protection for the outer surface of the lens barrel. The elastic protective net can effectively intercept flying debris, and the holes in the protective net can prevent the protective net from affecting the heat dissipation of the lens barrel. This allows the lens barrel to have a protective function while preventing its heat dissipation function from being affected. Moreover, the protective net can be removed, so it can be used for auxiliary protection after it is damaged. By setting up a detachable dustproof structure, the funnel frame can be disassembled and assembled with the help of the N pole magnet and S pole magnet, thereby providing auxiliary protection for the lens of the lens barrel. At the same time, the connection between the lens barrel and the funnel frame can be provided with auxiliary dust prevention with the help of the snap ring frame. Attached Figure Description

[0026] 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.
[0027] like Figures 1-5As shown, this embodiment provides a technical solution: a lens barrel structure with a detachable function, including a frame 1, a lens barrel body 2 disposed on one side of the frame 1, and a lens 5 disposed on one side of the lens barrel body 2; a disassembly and assembly protective structure 3 is provided on the outer surface of the lens barrel body 2, the disassembly and assembly protective structure 3 includes four circular inserts 34, and a protective net 35 is fixedly connected between two adjacent circular inserts 34. The protective net 35 is a perforated elastic net; the holes of the protective net 35 are extremely fine holes. A disassembly and assembly dustproof structure 4 is provided on one side of the lens barrel body 2, the disassembly and assembly dustproof structure 4 also includes a funnel frame 45, the bottom of the funnel frame 45 is transparent. By setting the disassembly and assembly protective structure 3, the protective net 35 can be disassembled and assembled, thereby allowing the lens barrel to be disassembled and assembled. The outer surface of the lens barrel 2 is provided with auxiliary protection. The elastic protective net 35 can effectively intercept the splashing of debris. At the same time, the protective net 35 can prevent the protective net 35 from affecting the heat dissipation of the lens barrel 2. This allows the lens barrel 2 to have a protective function while avoiding the heat dissipation function being affected. The protective net 35 is detachable, so it can be used for auxiliary protection after the protective net 35 is damaged. By setting up the disassembly and dustproof structure 4, the funnel frame 45 can be disassembled and assembled with the help of the N pole magnet 42 and the S pole magnet 43, thereby providing auxiliary protection for the lens 5 of the lens barrel 2. At the same time, the connection between the lens barrel 2 and the funnel frame 45 can be provided with auxiliary dust prevention with the help of the snap ring frame 46.
[0028] Going a step further, such as Figure 2 and Figure 5 As shown: The frame 1 is cubic in shape. Circular insert frames 31 are fixedly connected to all four sides of the frame 1. One end of a circular insert rod 34 is inserted into the inner wall of the circular insert frame 31. A threaded clamp rod 36 is fixedly connected to one end of the outer surface of the circular insert rod 34. A fixing nut 37 is threadedly connected to one end of the outer surface of the threaded clamp rod 36. The outer diameter of the threaded clamp rod 36 is smaller than the inner diameter of the circular insert frame 31, while the outer diameter of the fixing nut 37 is larger than the inner diameter of the circular insert frame 31. Four rectangular connecting blocks 32 are fixedly connected to the outer surface of the lens barrel 2, arranged circumferentially along the direction of the lens barrel 2. A semi-circular support frame 33 is fixedly connected to the top of the outer surface of the rectangular connecting blocks 32. The outer surface of the circular insert rod 34 overlaps with the semi-circular support frame 33. Under the action of the threaded clamp rod 36 and the fixing nut 37, the circular insert rod 34 and the circular insert frame 31 can be auxiliaryly fixed, thereby auxiliaryly fixing the protective net 35, allowing the protective net 35 to provide auxiliary protection for the lens barrel 2.
[0029] The above solution also has the problem of dust accumulation at the lens 5 inside the lens barrel 2, such as... Figure 2 and Figure 3As shown: In this solution, an annular block 41 is fixedly connected to the inner wall of the lens barrel 2, and an N-pole magnet 42 is fixedly connected to the inner wall of the annular block 41. An auxiliary ring plate 44 is fixedly connected to one side of the outer surface of the funnel frame 45, and an S-pole magnet 43 is fixedly connected to the inner wall of one side of the auxiliary ring plate 44. Under the action of the N-pole magnet 42 and the S-pole magnet 43, the funnel frame 45 can be assistedly fixed, thereby providing auxiliary protection for the lens barrel 2 without affecting its use.
[0030] The above solutions also have the problem of dust accumulation at the connection between the funnel frame 45 and the lens barrel 2, such as... Figure 3 and Figure 4 As shown, a snap ring frame 46 is fixedly connected to one side of the outer surface of the funnel frame 45. The snap ring frame 46 can provide auxiliary dust protection at the connection between the funnel frame 45 and the lens barrel 2.
[0031] Working principle:
[0032] like Figure 1-5 As shown:
[0033] When in use: insert the round insert rod 34 into the inner wall of the round insert frame 31. At this time, the round insert rod 34 connected to the protective net 35 overlaps with the semi-circular support frame 33. The threaded clamp rod 36 will pass through the inside of the round insert frame 31, thereby fixing the fixing nut 37 to the threaded clamp rod 36.
[0034] At this time, the protective net 35 can be fixed to the outer surface of the lens barrel 2, thereby providing auxiliary protection against debris splashed onto the outer surface of the lens barrel 2 and preventing scratches or other damage to the outer surface of the lens barrel 2.
[0035] The N-pole magnet 42 and the S-pole magnet 43 are magnetically attracted and fixed, thereby allowing the funnel frame 45 to be installed. At this time, the funnel frame 45 can provide auxiliary protection for the inner frame of the lens barrel 2, and under the action of the snap ring frame 46, it can also provide auxiliary protection for the outer surface of the funnel frame 45 and the lens barrel 2.
[0036] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
