Description

Technical Field

[0001] This utility model belongs to the field of lens technology, specifically relating to a high-safety large-diameter lens clamping mechanism. Background Technology

[0002] Large-aperture lenses have important applications in optical processing, testing, astronomical observation, and other fields. The stability and safety of their processing, assembly, and debugging are of paramount importance.

[0003] Currently, the industry commonly uses V-block supports or slings for the temporary storage, posture adjustment, and transportation of large lenses. V-blocks have a simple structure, but their support stability is limited. Lenses are prone to slipping or tipping over during pitch or sway adjustments, posing a safety hazard. While slings facilitate lifting, they are difficult to position precisely when adjusting angles, and the slings are prone to swaying, causing lenses to collide with surrounding equipment, resulting in lens damage or personal injury.

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-4 As shown, a high-safety large-diameter lens clamping mechanism includes a clamping unit and an adjusting bracket. The clamping unit is mounted on the adjusting bracket and includes two baffles 5 and a flexible support part installed between the two baffles 5. The two baffles 5 are fixedly connected. When the lens is placed on the flexible support part between the two baffles 5, the front and rear sides of the lens can be protected by the two baffles 5, effectively reducing the phenomenon of accidental tipping and accidental impact of the lens.

[0028] In some embodiments, an observation hole 10 may be provided on the baffle 5, and a transparent protective window is fixedly connected inside the observation hole 10 to facilitate the user to observe the lens between the two baffles 5.

[0029] Among them, such as Figures 1-3 As shown, the flexible support part includes a flexible support belt 9 located between two baffles 5. The two ends of the flexible support belt 9 are installed on the upper part between the two baffles 5. At this time, the lens can be placed inside the flexible support belt 9, which can quickly limit the lens, improve the stability of the lens, and improve the efficiency of fixing the lens.

[0030] Specifically, a connecting post 7 is rotatably connected to the upper part between the two baffles 5. A first fine threaded rod 8 is threaded onto the connecting post 7. One end of the first fine threaded rod 8 is rotatably connected to the end of the flexible support belt 9. The position of the end of the flexible support belt 9 can be adjusted by rotating the first fine threaded rod 8.

[0031] At the same time, such as Figures 1-3 As shown, multiple rotating shafts 6 are rotatably connected between the two baffles 5. The rotating shafts 6 are located on the outside of the flexible support belt 9 and are used to limit the flexible support belt 9.

[0032] like Figures 1-3As shown, a connecting hole plate 18 is also fixedly connected to the upper part between the two baffles 5. The connecting hole plate 18 can be used to easily connect the lifting device and lift the lens. The connecting hole plate 18 can be connected by welding, screw connection or snap-fit.

[0033] like Figures 1-2 As shown, the adjustment bracket includes a lower bracket 1, an upper bracket 2 is rotatably connected to the upper side of the lower bracket 1, and side brackets 3 are fixedly connected to both sides of the upper bracket 2. Rotary connectors 4 are fixedly connected to both sides of the two baffle 5 assemblies. The rotating connectors 4 and the side brackets 3 are rotatably connected. At this time, the torsional angle of the lens can be adjusted by rotating the upper bracket 2, and the tilt angle of the lens can be adjusted by rotating the baffle 5. The tilt and torsional adjustment angles are preferably ±20°.

[0034] Meanwhile, connecting brackets 15 are fixedly connected to both the front and rear sides of the upper bracket 2. The connecting brackets 15 are threaded with a second fine thread rod 16 that matches the baffle 5. By rotating the second fine thread rod 16, the baffle 5 can be rotated to adjust the pitch angle of the baffle 5. The fine thread rod adjustment is more precise and the accuracy is stable over long-term use. All of them are equipped with a self-locking function, which can effectively lock and maintain stability after adjustment.

[0035] Connecting brackets 15 are also fixedly connected to the front and rear sides of the lower bracket 1. The connecting brackets 15 are threaded with a second fine thread rod 16 that is compatible with the upper bracket 2. By rotating the second fine thread rod 16, the upper bracket 2 can be rotated to adjust the torsion angle of the upper bracket 2. The fine thread rod adjustment is more precise and the accuracy is stable over long-term use. Both are equipped with a self-locking function, which can effectively lock and maintain stability after adjustment. The setting of two sets of second fine thread rods 16 makes it relatively easy to adjust the lens angle.

[0036] One end of the second fine threaded rod 16 is fixedly connected to a hemisphere 17 to reduce the contact between the edges of the second fine threaded rod 16 and the baffle 5 or the upper bracket 2.

[0037] At the same time, such as Figure 4 As shown, support plates 11 are fixedly connected to both sides of the lower bracket 1, and rotatable casters 14 are installed on the support plates 11. The casters 14 facilitate the movement of the clamping unit on the ground.

[0038] In some embodiments, an electric telescopic rod 12 is fixedly connected to the lower side of the support plate 11, and a Z-shaped connecting plate 13 is fixedly connected to the piston rod of the electric telescopic rod 12. The moving wheel 14 is mounted on the Z-shaped connecting plate 13. The height of the moving wheel 14 can be adjusted by starting the electric telescopic rod 12. When the moving wheel 14 is separated from the ground, the lower support 1 can directly contact the ground, thereby improving the placement stability.

[0039] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
