Large-size lens buffering device

Abstract

The utility model provides a buffer device for a large-size lens. The buffer device comprises a bracket and an elastic sheet, mounting tables are convexly arranged on the surfaces of the two ends of the bracket. The two ends of the elastic piece are installed on the installation tables respectively, so that a deformation gap is reserved between the elastic piece and the support. When the large-size lens buffer device is used, a plurality of lens buffer devices are distributed in the circumferential direction of a lens, and the elastic pieces of the lens buffer devices abut against the edge of the lens. Meanwhile, the plurality of brackets are attached to the glasses frame, so that the lenses are connected to the interior of the glasses frame through the buffer devices. As the elastic sheet is jacked up by the mounting tables at the two ends, a deformation gap is formed between the elastic sheet and the bracket. When the equipment vibrates, the lens pushes the elastic sheet. And due to the existence of the deformation gap, the elastic sheet can generate certain deformation, so that the lens is buffered. Therefore, the lenses and the glasses frame are not in rigid connection any more, and the anti-vibration performance of the lenses is higher.

Description

Technical Field

[0001] The utility model relates to the technical field of lens brackets, in particular to a large-size lens buffer device. Background Art

[0002] Lenses are important parts of optical instruments. For small lenses, since the lenses themselves are small and light, the impact force generated by shaking during use is small. Therefore, it will not cause a big impact on itself. However, for lenses with a diameter of about 500mm, their weight and size are both large. If shaking occurs, a large force will be generated. However, the frames of the prior art are hard frames, which cannot be buffered when shaking occurs, and the huge force will damage the lenses. Utility Model Content

[0003] The utility model aims to provide a large-size lens buffer device, which can buffer the lens and thus protect the lens.

[0005] A large-size lens buffer device comprises a bracket and an elastic sheet; mounting platforms are protruding from the surfaces of both ends of the bracket; both ends of the elastic sheet are respectively mounted on one of the mounting platforms, so that a deformation gap is reserved between the elastic sheet and the bracket.

[0006] Furthermore, both ends of the elastic sheet and the mounting platform are provided with through holes for the screw to pass through; the spacing between the through holes at both ends of the elastic sheet is smaller than the spacing between the mounting holes of the two mounting platforms and the distance difference between the two is 1-2 mm.

[0007] Furthermore, each of the mounting platforms and the end of the elastic sheet are cooperatively provided with three mounting holes; a gasket is also provided between the elastic sheet and the nut; and one mounting hole is provided on the gasket corresponding to each mounting hole.

[0008] Furthermore, the upper part of the mounting hole of the mounting platform is a large diameter section; a bolt is passed through the mounting hole to connect the elastic sheet to the mounting platform; an elastic ring is sleeved between the bolt and the hole wall of the mounting hole; the elastic ring extends from the mounting hole of the gasket to the inside of the large diameter section.

[0009] Furthermore, the inner diameter of the large diameter section is larger than the inner diameter of the mounting holes of the gasket and the elastic sheet.

[0010] Furthermore, the diameter of the mounting hole of the gasket is smaller than the outer diameter of the nut.

[0012] Furthermore, a positioning hole for fixing the positioning member is provided in the middle of the elastic sheet; and an operating hole is provided in the bracket corresponding to the positioning hole.

[0013] The technical solution of the embodiment of the utility model has at least the following advantages and beneficial effects:

[0014] When the large-size lens buffer device of the utility model is used, a plurality of lens buffer devices are distributed along the circumference of the lens, and the elastic sheet thereof is pressed against the edge of the lens. At the same time, a plurality of brackets are fitted to the frame for installation, so that the lens is connected to the inside of the frame through the buffer device.

[0023] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0024] Example:

[0025] like Figure 1-6 As shown, the utility model provides a buffer device for a large-size lens 12, comprising a bracket 1 and an elastic sheet 2. Mounting platforms 3 are protruding from the surfaces of both ends of the bracket 1. Both ends of the elastic sheet 2 are mounted on a mounting platform 3, so that a deformation gap 4 is reserved between the elastic sheet 2 and the bracket 1. Specifically, the elastic sheet 2 can be connected to the mounting platform 3 by screws or welding.

[0026] When the large-size lens 12 buffer device of the utility model is used, a plurality of lens 12 buffer devices are distributed along the circumference of the lens 12, and the elastic sheet 2 is pressed against the edge of the lens 12. At the same time, a plurality of brackets 1 are installed in a close fit to the frame, so that the lens 12 is connected to the inside of the frame through the buffer device. Since the elastic sheet 2 is lifted up by the mounting platforms 3 at both ends, a deformation gap 4 is formed between it and the bracket 1. When the equipment vibrates, the lens 12 pushes the elastic sheet 2. Due to the existence of the deformation gap 4, the elastic sheet 2 can produce a certain deformation, thereby buffering the lens 12. This means that the lens 12 and the frame are no longer rigidly connected, making the lens 12 more resistant to vibration. In order to better generate elastic force, the elastic sheet 2 is made of spring steel.

[0027] In this embodiment, both ends of the elastic sheet 2 and the mounting platform 3 are provided with mounting holes 5 for the screw to pass through. When the elastic sheet 2 is placed on the mounting platform 3, the mounting holes 5 of the elastic sheet 2 correspond to the mounting holes 5 of the mounting platform 3, which is convenient for inserting the screw. The spacing between the mounting holes 5 at both ends of the elastic sheet 2 is smaller than the spacing between the mounting holes 5 of the two mounting platforms 3, and the distance difference between the two is 1-2mm. This makes the mounting holes 5 of the elastic sheet 2 and the mounting holes 5 of the mounting platform 3 staggered a little bit.

[0028] Since the diameter of the mounting hole 5 is slightly larger than the outer diameter of the bolt, the bolt can shake to a certain extent in the mounting hole 5. This also means that when the bolt connects the elastic sheet 2 to the mounting platform 3, the elastic sheet 2 can still shake slightly, and it is not tightened. This will affect the elastic effect of the elastic sheet 2 to a certain extent. The spacing between the mounting holes 5 at both ends of the elastic sheet 2 is smaller than the spacing between the mounting holes 5 of the two mounting platforms 3, and the distance difference between the two is 1-2mm, so that the elastic sheet 2 is in a tightened state, thereby enabling the elastic sheet 2 to provide better elastic force, thereby enabling the elastic sheet 2 to better buffer the lens 12.

[0029] In this embodiment, each mounting platform 3 and the end of the elastic sheet 2 are matched to be provided with three mounting holes 5. A gasket 6 is also provided between the elastic sheet 2 and the nut. The gasket 6 is provided with a mounting hole 5 corresponding to each mounting hole 5. The gasket 6 presses down the part of the elastic sheet 2 at the three mounting holes 5 to make the integrity better.

[0030] In this embodiment, the upper part of the mounting hole 5 of the mounting platform 3 is a large diameter section 7, which has a larger inner diameter. Bolts are inserted into the mounting hole 5 to connect the elastic sheet 2 to the mounting platform 3. An elastic ring 8 is sleeved between the bolt and the hole wall of the mounting hole 5. The elastic ring 8 can be made of rubber. The elastic ring 8 extends from the mounting hole 5 of the gasket 6 to the inside of the large diameter section 7. This means that the elastic ring 8 is also padded between the elastic sheet 2 and the bolt. When the elastic sheet 2 is deformed by the thrust of the lens 12, the elastic sheet 2 squeezes the elastic ring 8. Since the elastic ring 8 is elastic and relatively soft, the elastic sheet 2 is softer and more effectively protects the lens 12. In addition, the elastic ring 8 extends from the mounting hole 5 of the gasket 6 to the inside of the large diameter section 7, so that the elastic ring 8 has margins above and below the elastic sheet 2, thereby preventing the elastic sheet 2 from slipping off the elastic ring 8.

[0031] In this embodiment, the inner diameter of the large diameter section 7 is larger than the inner diameter of the gasket 6 and the mounting hole 5 of the elastic sheet 2. In the process of the bolt gradually locking the gasket 6, the elastic sheet 2 and the mounting platform 3, the elastic ring 8 is gradually squeezed and deformed and bulges. Then the elastic sheet 2 is tightened. At the same time, the inner diameter of the large diameter section 7 is larger than the inner diameter of the gasket 6 and the mounting hole 5 of the elastic sheet 2, so that there is still a gap inside the large diameter section 7 to accommodate the elastic ring 8. Then the elastic ring 8 is squeezed into the gap without being squeezed too tightly and losing its elasticity. At the same time, the elastic state of the elastic ring 8 can also be adjusted by adjusting the locking condition of the bolt, so that the elasticity of the elastic sheet 2 to the lens 12 can be adjusted. Specifically, the greater the degree of bolt locking, the tighter the elastic ring 8 is squeezed, and the worse the elastic effect.

[0032] In this embodiment, the diameter of the mounting hole 5 of the gasket 6 is smaller than the outer diameter of the nut, so that the elastic ring 8 can be effectively compressed when the nut is compressed against the gasket 6 .

[0033] In this embodiment, a positioning member 9 connected to the elastic sheet 2 is further included. One side of the positioning member 9 is fixed to the elastic sheet 2 by screws, and the other side is provided with a groove for accommodating the edge of the lens 12. During installation, the edge of the lens 12 is clamped in the groove to effectively connect the lens 12 to the elastic sheet 2.

[0034] In this embodiment, a positioning hole 10 for fixing the positioning member 9 is provided in the middle of the elastic sheet 2. An operating hole 11 is provided in the bracket 1 corresponding to the positioning hole 10. The operating hole 11 makes it more convenient to insert the bolt into the positioning hole 10 and screw it.

[0035] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
