Description

Technical Field

[0001] This utility model relates to the field of lens bracket technology, and in particular to a lens auxiliary locking bracket and device. Background Technology

[0002] Currently, most zoom lenses do not come with a lens mount. When shooting, a base plate needs to be mounted on the camera body, and then fixed to a tripod head. While this reduces camera shake and assists shooting, it is cumbersome and takes up considerable space. Secondly, although some telephoto lenses do provide lens mounts, these mounts are often of fixed size with only one locking knob. They can only be used with a specific lens or different lens models with identical mounting structures, failing to meet the needs of various lenses and limiting their versatility.

[0003] By setting two different knobs on the lens mount ring, the small space between the lens and the camera body is fully utilized, which not only solves the problem of stability during shooting but also expands its applicability. One knob is used to tighten or loosen the mount ring, while the other knob changes the force point between the tripod ring support and the lens by pushing or pulling an adjustment block embedded in the inner wall of the ring, thus helping to lock or loosen the lens.

[0038] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0039] Please refer to Figures 1-8 This utility model proposes a lens-assisted locking bracket and device, including a ring body 1, a first adjusting member 2, and a second adjusting member 3; the first adjusting member 2 and the second adjusting member 3 are respectively disposed on the ring body 1; the ring body 1 is provided with an extension 13, the extension 13 including a first extension 131 and a second extension 132; the first adjusting member 2 is disposed on the extension 13 and is movably connected to the first extension 131 and the second extension 132 respectively; an adjusting gap 4 is provided between the first extension 131 and the second extension 132, the adjusting gap 4 being used to adjust the tightness of the ring body 1; the ring body 1 is also provided with a first through hole 11 and a placement groove 12, the first through hole 11 being used to fix the second adjusting member 3, and the placement groove 12 being used to place the second adjusting member 3.

[0040] In this embodiment, the ring 1 is provided with an extension 13, which includes a first extension 131 and a second extension 132. An adjustment gap 4 is provided between the first extension 131 and the second extension 132 (i.e., the ring 1 is a non-closed ring 1). The adjustment gap 4 is used to adjust the tightness of the ring 1. Specifically, a first adjusting member 2 is provided on the extension 13 and is movably connected to the first extension 131 and the second extension 132 respectively. The size of the adjustment gap 4 is adjusted by the first adjusting member 2 to tighten or loosen the ring 1. The ring body 1 is also provided with a first through hole 11 and a placement groove 12. The first through hole 11 is used to fix the second adjusting member 3, and the placement groove 12 is used to place the second adjusting member 3. The placement groove 12 is located on the inner side of the ring body 1. The second adjusting member 3 moves through the first through hole 11, with one end of the second adjusting member 3 located on the outer side of the ring body 1 and the other end located in the placement groove 12. By adjusting the second adjusting member 3 (i.e., the small knob 31) located on the outer side of the ring body 1, the second adjusting member 3 (i.e., the adjusting block 33) located in the placement groove 12 on the inner side of the ring body 1 can be pushed or pulled, thereby changing the force point between the ring body 1 and the lens, and realizing the auxiliary locking or loosening of the lens.

[0041] More specifically, the first adjusting member 2 and the second adjusting member 3 are diagonally arranged on the ring body 1. The first adjusting member 2 and the second adjusting member 3 are positioned at different locations to apply force, forming a more stable structure. This ensures that the lens is evenly stressed in different directions, thereby achieving a more secure fixation and reducing the possibility of loosening. When the first adjusting member 2 is tightened, the force points of the ring body 1 and the lens can be adjusted using the second adjusting member 3 to avoid uneven force distribution between the ring body 1 and the lens, which could lead to lens tilting or bracket deformation.

[0042] Please refer to Figure 1 , Figure 3 and Figure 5 The placement groove 12 is located on the inner side of the ring body 1. The second adjusting member 3 is movably connected to the first through hole 11 and passes through the first through hole 11, so that one end of the second adjusting member 3 is located on the outer side of the ring body 1 and the other end is located in the placement groove 12.

[0043] In specific implementation: the placement groove 12 is located on the inner side of the ring body 1. The second adjusting member 3 includes a small knob 31 and an adjusting block 33. The second adjusting member 3 is located within the placement groove 12. Specifically, the adjusting block 33 is located within the placement groove 12. The small knob 31 passes through the first through hole 11 on the ring body 1 and connects with the adjusting block 33 within the placement groove 12. This results in one end of the second adjusting member 3 being located on the outer side of the ring body 1 (i.e., the small knob 31 is located on the outer side of the ring body 1), and the other end of the second adjusting member 3 being located on the inner side of the ring body 1 (i.e., the adjusting block 33 is located in the placement groove 12 on the inner side of the ring body 1), so as to adjust the force point between the ring body 1 and the lens. The arc surface of the adjusting block 33 located on the inner side of the ring body 1 is consistent with the arc surface of the inner side of the ring body 1, allowing for a closer fit to the lens surface, thus providing better support and fixation. This ensures that the adjusting block 33 helps to distribute the pressure on the lens, reducing pressure and wear on the lens, while also improving the user experience and product versatility.

[0044] Please refer to Figure 1 , Figure 3 and Figure 5 The first adjusting component 2 includes a large knob 21 and a large screw 22; the first extension 131 is provided with an adjusting groove 1311, the second extension 132 is provided with a second through hole 1321, and the second through hole 1321 is correspondingly provided with the adjusting groove 1311; the large screw 22 passes through the second through hole 1321 and is movably connected with the adjusting groove 1311.

[0045] In specific implementation: the first adjusting component 2 includes a large knob 21 and a large screw 22, wherein the large screw 22 is threaded, the second extension 132 of the ring body 1 is provided with a second through hole 1321, the first extension 131 is provided with an adjusting groove 1311, and the second through hole 1321 corresponds to the opening of the adjusting groove 1311. The large knob 21 is connected to the ring body 1 through the large screw 22. During assembly, the large screw 22 passes through the second through hole 1321 and abuts against the adjustment groove 1311. The gap between the first extension 131 and the second extension 132 is adjusted by rotating the large knob 21. When the large knob 21 is rotated clockwise, it moves horizontally toward the first extension 131 and causes the second extension 132 to move closer to the first extension 131 (i.e., the adjustment gap 4 between the first extension 131 and the second extension 132 becomes smaller), thereby tightening the ring body 1 to fix the lens. When the large knob 21 is rotated counterclockwise, it moves horizontally away from the first extension 131. The ring body 1 can recover its deformation according to the material properties of the body or adjust the size of the gap according to the actual size of the object (i.e., the adjustment gap 4 between the first extension 131 and the second extension 132 becomes larger), and causes the second extension 132 to move away from the first extension 131, thereby loosening the ring body 1 to release the lens.

[0046] Please refer to the attached document. Figure 1 and Figures 5-7 The second adjusting component 3 includes a small knob 31, an adjusting block 33, and a pin 34. The small knob 31 is located on the outside of the ring body 1, the adjusting block 33 is located in the placement groove 12, and the small knob 31 is provided with a small screw 32. The small screw 32 movably passes through the first through hole 11 and is movably connected to the adjusting block 33.

[0047] In specific implementation: the ring body 1 is provided with a first through hole 11, and the second adjusting member 3 movably passes through the first through hole 11 and is fixed to the ring body 1. The second adjusting member 3 includes a small knob 31, an adjusting block 33, and a pin 34; wherein, the small knob 31 is provided with a small screw 32, and the end of the small screw 32 away from the small knob 31 is provided with an annular groove 321. The small screw 32 located between the small knob 31 and the annular groove 321 is provided with a thread, and the first through hole 11 is also provided with a thread. The thread of the small screw 32 engages with the thread on the first through hole 11, thereby allowing the small screw 32 to pass through the first through hole 11 and be movably connected to the adjusting block 33; by rotating the small knob 31, the small screw 32 moves in the axial direction, thereby pushing or pulling the adjusting block 33 located in the placement groove 12 inside the ring body 1.

[0048] Please refer to the attached document. Figure 1 , Figure 7 and Figure 8 The adjusting block 33 is provided with a fixing groove 331 and a pin groove 332. The fixing groove 331 is located on the side of the adjusting block 33 near the ring body 1 and is corresponding to the first through hole 11. The pin groove 332 is connected to the fixing groove 331 and is perpendicular to the fixing groove 331.

[0049] In specific implementation: the second adjusting component 3 includes a small knob 31, an adjusting block 33, and a pin 34; the adjusting block 33 is provided with a fixing groove 331 and a pin groove 332, and the end of the small screw 32 away from the small knob 31 abuts against the fixing groove 331 and is fixed by the pin 34. Specifically, the fixing groove 331 is provided on the side of the adjusting block 33 near the ring body 1, and the fixing groove 331 is vertically provided on the side near the ring body 1. The opening of the fixing groove 331 is corresponding to the first through hole 11. The pin groove 332 is perpendicular to the fixing groove 331 and communicates with the fixing groove 331. The pin 34 corresponds to the pin groove 332 to ensure that the pin 34 can be smoothly inserted and fixed.

[0050] More specifically, the pin groove 332 is located on the side of the adjusting block 33 near the side wall of the ring body 1 (that is, the two sides of the adjusting block 33 abut against the two sides of the placement groove 12 respectively, one side is used to set the fixing groove 331, and the other side is used to set the pin groove 332). The opening of the pin groove 332 is set opposite to the side of the placement groove 12 to prevent the pin 34 from loosening and falling off.

[0051] In one specific embodiment, a steel needle is used as the pin 34. The steel needle has high strength, can withstand large forces without deformation, and is durable, maintaining its performance during frequent use.

[0052] Please refer to the attached document. Figures 6-8 The end of the small screw 32 away from the small knob 31 is provided with an annular groove 321. The small screw 32 moves through the first through hole 11 and the annular groove 321 is located in the fixed groove 331.

[0053] In specific implementation: The end of the small screw 32 away from the small knob 31 is provided with an annular groove 321. During assembly, the thread of the small screw 32 engages with the thread on the first through hole 11, and passes through the first through hole 11 to abut against the fixing groove 331 on the adjusting block 33, so that the annular groove 321 corresponds to the pin groove 332. Then, the pin 34 is inserted into the pin groove 332. The pin 34 passes through the annular groove 321 until it abuts against the bottom of the pin groove 332. The pin 34 limits and fixes the small screw 32, so that the small screw 32 can be firmly connected to the adjusting block 33. Thus, when the small knob 31 is rotated, the adjusting block 33 is pushed or pulled to change the inner diameter of the ring body 1, so as to be suitable for more lenses with similar but not completely the same structure and similar but not completely the same size.

[0054] Please refer to the attached document. Figure 1 and Figures 6-8 The pin 34 engages with the pin groove 332 and abuts against the annular groove 321 to fix the small screw 32.

[0055] In specific implementation: the pin 34 is set correspondingly to the pin groove 332. After the small screw 32 of the second adjusting member 3 moves through the first through hole 11 of the ring body 1 and abuts against the fixing groove 331 of the adjusting block 33, the pin 34 is inserted into the pin groove 332. The position of the annular groove 321 corresponds to the pin groove 332. When the pin 34 is assembled into the pin groove 332, the pin 34 will pass through the annular groove 321 and provide support and fixation to the annular groove 321. After assembly, the annular groove 321 is engaged with the pin 34 to ensure that the small screw 32 does not easily disengage from the fixing groove 331 of the adjusting block 33.

[0056] Please refer to the attached document. Figure 1 The adjusting block 33 corresponds to the placement groove 12, and the arc surface of the adjusting block 33 on the side away from the fixed groove 331 is consistent with the arc surface of the inner side of the ring 1.

[0057] In practical implementation: the placement groove 12 corresponds to the adjusting block 33. When the adjusting block 33 is located in the placement groove 12, the arc surface of the adjusting block 33 away from the placement groove 12 (i.e., the side that contacts the lens) is consistent with the arc surface of the inner side of the ring 1, ensuring that the lens can fit tightly with the adjusting block 33 when fixed, so as to provide better support and fixation. The material of the adjusting block 33 includes, but is not limited to, plastic, alloy, and rubber.

[0058] In one specific embodiment, the adjustment block 33 is made of plastic. Plastic has a low density, and compared with metal materials, the plastic adjustment block 33 can significantly reduce the weight of the overall ring 1, making it easier to carry and operate. The raw material cost of plastic is relatively low, and the molding process is relatively mature. It can be processed by injection molding and other methods to manufacture complex shapes and fine structures to meet the design requirements of the adjustment block 33. In addition, plastic is not easy to rust, making it suitable for use in humid or dusty environments, thereby extending the service life of the adjustment block 33. Furthermore, plastic also has good cushioning and shock absorption properties, which can effectively reduce the vibration of the lens during movement or collision, protecting the lens from damage.

[0059] Please refer to the attached document. Figures 1-3 The inner arc surface of the ring 1 and the arc surface of the adjusting block 33 are respectively provided with anti-slip parts 5 to increase friction.

[0060] In practical implementation: the anti-slip component 5 increases friction, ensuring that the lens and other equipment do not slip due to external forces during adjustment, providing a more stable fixation; the anti-slip component 5 also effectively protects the lens surface, preventing scratches or wear caused by direct contact with the metal or hard material ring 1. The anti-slip component 5 is typically made of soft or elastic materials and has certain cushioning and shock absorption properties, reducing the impact of vibration on the ring 1 during use and improving stability. The materials of the anti-slip component 5 include, but are not limited to, rubber and silicone.

[0061] Please refer to the attached document. Figure 1 The ring body 1 is provided with a fixing plate 6, which is located below the first extension 131 and is fixedly connected to the first extension 131.

[0062] In practical implementation: A fixing plate 6 is installed below the extension 13 of the ring body 1. The fixing plate 6 provides a stable connection point with other equipment, ensuring that the ring body 1 will not loosen or fall off due to external forces during use, thus improving the overall structural stability. The fixing plate 6 effectively reduces the shaking of the ring body 1 bracket caused by equipment vibration or external forces during use, ensuring shooting stability. The fixing plate 6 is typically designed with a universal interface, adaptable to different types of tripods, pedestals, or slide rails, increasing the compatibility and applicability of the ring body 1. The fixing plate 6 is designed with quick-installation and disassembly mechanisms, such as quick-release screws, clips, or slide rails, allowing users to quickly connect and disconnect equipment, improving operational efficiency. The fixing plate 6 is typically made of high-strength materials, including but not limited to stainless steel and aluminum alloy, to ensure sufficient durability and load-bearing capacity, extending the product's lifespan.
