Description

Technical Field

[0001] This utility model relates to the field of optical mirror structure technology, specifically an optical mirror structure for television engineering. Background Technology

[0002] The Broadcasting and Television Engineering major is guided by the development needs of the modern information technology industry and emphasizes the cross-integration with related majors such as computer science, automation control, and electronic information.

[0003] Currently, common optical lens structures used in television engineering occupy a large space, making them inconvenient to carry, and are also quite troublesome to assemble and position with camera lenses. For example, an optical lens structure for broadcast television engineering disclosed in publication number CN216351717U includes a first clamping plate with an adjusting bolt threaded to its side. One end of the adjusting bolt passes through the first clamping plate and is connected to a second clamping plate for clamping via a bearing. A connecting frame for connection is fixedly connected to the top of the second clamping plate. A rotatable movable cylinder is sleeved on one end of the connecting frame. An extension plate for extension is fixedly connected to the side of the movable cylinder.

[0004] As can be seen from the above-disclosed scheme, the optical lens structure clamps the first and second clamping plates at the lens by adjusting the bolts, and then switches the lens barrel screw for positioning, which reduces the ease of use of the optical lens structure. Moreover, the cross-shaped extension plate not only has a small number of lenses installed, but also occupies a large space, making it inconvenient to carry the optical lens structure. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a light mirror structure for television engineering, which solves the problems of large space occupation and inconvenience in carrying existing light mirror structures, as well as the inconvenience in assembling the light mirror structure with the camera lens.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lens structure for television engineering, comprising a lens structure body, the lens structure body including a positioning component, a storage component, and a lens switching component, the positioning component and the storage component being fixedly connected, the lens switching component and the storage component being slidably connected, the positioning component including a positioning sleeve, one end of the positioning sleeve having a sleeve hole, the inner wall of the sleeve hole being fixedly connected to a ring of equally spaced clamping blocks, and one end of the positioning sleeve being fixedly connected to a ring of equally spaced elastic telescopic rods. Through the clamping blocks, elastic plate, and elastic telescopic rods, not only is it convenient for the positioning sleeve to be fixed to the camera lens by elastic force, but the replacement lens body can also be fixed to one end of the camera lens by elastic force, improving ease of use. Furthermore, through the support plate, first anti-detachment plate, second anti-detachment plate, and anti-detachment groove, compared with existing lens structures, the space occupied is greatly reduced, and the number of lens bodies that can be stored is increased, improving portability.

[0007] Preferably, the storage component includes a support plate, the surface of which is fixedly connected to one end of an elastic telescopic rod, and the other surface of which is fixedly connected to a first anti-detachment plate and a second anti-detachment plate. An anti-detachment groove is formed between the support plate, the first anti-detachment plate, and the second anti-detachment plate. The anti-detachment groove can store multiple lens switching components, and the multiple lens switching components can be moved and adjusted in position.

[0008] Preferably, the lens switching assembly includes a fixing sleeve, on the inner wall of which a lens body is fixedly connected. An upper anti-detachment ring is fixedly connected to one end of the fixing sleeve, and a lower anti-detachment ring is fixedly connected to the other end of the fixing sleeve. The fixing sleeve is used to install the lens body, and different fixing sleeves can install different lens bodies for easy switching.

[0009] Preferably, the clamping block is made of elastic wear-resistant rubber, and an elastic plate is fixedly laminated inside the clamping block. The elastic plate is made of arc-shaped elastic steel sheet. After the clamping block is pressed against the lens surface, it generates compressive elastic force. The clamping block is fixed in position on the lens surface by the elastic clamping force.

[0010] Preferably, a limiting groove is formed between the upper anti-detachment ring, the lower anti-detachment ring and the fixing sleeve, and the surface of the lower anti-detachment ring is slidably connected to the inner wall of the anti-detachment groove. The limiting groove can limit the position of the fixing sleeve and prevent it from detaching from the anti-detachment groove.

[0011] Preferably, the support plate has a central hole at its center, one end of which is connected to the anti-detachment groove. The inner diameter of the central hole is larger than the outer diameter of the lower anti-detachment ring, so that the lower anti-detachment ring can contact and press against one end of the lens, thereby fixing the lens body to one end of the lens through elasticity.

[0012] Preferably, both ends of the clamping block are provided with guide surfaces, which are inclined surfaces to facilitate the lens fitting into the sleeve hole.

[0013] Compared with the prior art, this utility model provides a light mirror structure for television engineering, which has the following beneficial effects: By incorporating clamping blocks, elastic plates, and elastic telescopic rods, the positioning sleeve can be easily fixed to the camera lens using elastic force. At the same time, the replacement lens body can be fixed to one end of the camera lens using elastic force, improving ease of use.

[0016] 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.

[0017] This utility model provides a technical solution: a lens structure for television engineering, comprising a lens structure body 1, which includes a positioning component 2, a storage component 3, and a lens switching component 4. The positioning component 2 is used to engage with a camera lens, thereby mounting the lens structure body 1 onto the camera lens and facilitating manual assembly and disassembly. The storage component 3 houses multiple lens switching components 4, each with different lens bodies 42, allowing for easy switching between lenses during shooting. Compared to other components, the storage component 3 occupies less space while housing more lens bodies 42. The lens switching components 4 fix the lens bodies 42 and allow them to slide freely on the storage component 3, thus improving the ease of switching between lens bodies 42. The positioning component 2 and the storage component 4... The lens switching assembly 4 and the storage assembly 3 are fixedly connected. The positioning assembly 2 includes a positioning sleeve 21. The positioning sleeve 21 is fixed in position by the compression elastic force of the lens and the clamping block 24. The installation is simple and quick. One end of the positioning sleeve 21 has a sleeve hole 22. The inner wall of the sleeve hole 22 is fixedly connected to a ring of equally spaced clamping blocks 24. One end of the positioning sleeve 21 is fixedly connected to an ring of equally spaced elastic telescopic rods 23. After the positioning sleeve 21 is clamped and fixed to the lens, one end of the elastic telescopic rod 23 is in a state of tension elasticity. The elasticity is less than the elastic clamping force of the clamping block 24, so the positioning sleeve 21 will not move at will. At the same time, the elasticity of the elastic telescopic rod 23 causes one end of the lens switching assembly 4 in the central hole 35 to contact and compress with one end of the lens. The position of the switched lens body 42 is positioned by the elasticity.

[0018] The storage component 3 includes a support plate 31. The surface of the support plate 31 is fixedly connected to one end of the elastic telescopic rod 23. The other surface of the support plate 31 is fixedly connected to a first anti-detachment plate 32 and a second anti-detachment plate 33. The second anti-detachment plate 33 is provided with a U-shaped opening. The width of the U-shaped opening is larger than the outer diameter of the lens body 42, so it will not block it. The support plate 31, the first anti-detachment plate 32 and the second anti-detachment plate 33 form an anti-detachment groove 34. The anti-detachment groove 34 can store multiple lens switching components 4. At the same time, the multiple lens switching components 4 can be moved and adjusted. The clamping block 24 is made of elastic wear-resistant rubber. An elastic plate 26 is fixedly composited inside the clamping block 24. The elastic plate 26 is made of arc-shaped elastic steel sheet. After the clamping block 24 is pressed against the lens surface, it generates a compressive elastic force. The clamping block 24 fixes the positioning sleeve 21 to the position on the lens surface through the elastic clamping force.

[0019] The lens switching assembly 4 includes a fixing sleeve 41, on the inner wall of which a lens body 42 is fixedly connected. An upper anti-detachment ring 44 is fixedly connected to one end of the fixing sleeve 41, and a lower anti-detachment ring 43 is fixedly connected to the other end of the fixing sleeve 41. The fixing sleeve 41 is used to install the lens body 42, and different fixing sleeves 41 can install different lens bodies 42 for easy switching. A limiting groove 45 is formed between the upper anti-detachment ring 44, the lower anti-detachment ring 43 and the fixing sleeve 41. The surface of the lower anti-detachment ring 43 is slidably connected to the inner wall of the anti-detachment groove 34. The limiting groove 45 can limit the position of the fixing sleeve 41 to prevent it from detaching from the anti-detachment groove 34.

[0020] The support plate 31 has a central hole 35 at its center. The central hole 35 is coaxial with the sleeve hole 22, which facilitates the switching of the lens body 42 and the lens. One end of the central hole 35 is connected to the anti-detachment groove 34. The inner diameter of the central hole 35 is larger than the outer diameter of the lower anti-detachment ring 43, and also larger than the outer diameter of one end of the lens, so that the lower anti-detachment ring 43 can contact and squeeze with one end of the lens, thereby fixing the lens body 42 to one end of the lens through elasticity. Both ends of the clamping block 24 are provided with guide surfaces 25. The guide surfaces 25 are inclined surfaces, which facilitates the lens to be inserted into the sleeve hole 22.

[0021] The working principle of this device is as follows: In use, the positioning sleeve 21 is first inserted into the sleeve hole 22 from one end of the camera lens, so that the surface of the lens is pressed against the clamping block 24, causing the clamping block 24 and the elastic plate 26 to deform and generate elastic force. The positioning sleeve 21 is fixed in place by the elastic force. Then, the support plate 31 is manually pulled towards the lens end, so that the elastic telescopic rod 23 generates tensile force. Then, the required lens body 42 is moved to the lens end. First, the lens body 42 in the anti-detachment groove 34 is located. Then, the lens switching assembly 4 with the lens body 42 is manually moved along the anti-detachment groove 34 to the position of the center hole 35. At this time, the support plate 31 is released, so that the elastic telescopic rod 23 releases its elastic force. Under the action of the elastic force, the support plate 31 moves towards the lens end, so that the lower anti-detachment ring 43 set on the lens switching assembly 4 at one end of the center hole 35 abuts against the lens end, thereby fixing the use position of the lens body 42 by the elastic force.
