Description
Technical Field
[0001] The utility model relates to the technical field of spectacle frames, in particular to a vibration-proof optical spectacle frame. Background Art
[0002] The function of the optomechanical frame is to support and fix optical components, such as lenses, mirrors, etc., to ensure the stability of their position and direction in the optical system. The optomechanical frame is usually made of metal or alloy materials, with a stable structure and highly precise processing to ensure the precise control of the position and angle of the optical components. The optomechanical frame can achieve fine-tuning and precise positioning of optical components by adjusting screws or other adjustment devices. In addition, the optomechanical frame can also provide protection and isolation for optical components to prevent interference and damage to the optical components by the external environment.
[0003] In actual applications, during transportation and use, the optical components held by the optical frame will change position due to the influence of vibration and thermal interference, and these interferences will also affect the relevant optical properties of the optical components, such as reflectivity and wavefront distortion. These changes will directly lead to changes in important parameters such as beam pointing, optical power and beam quality of the entire optical-mechanical system. In severe cases, it may even cause the system to fail to operate normally. If you want to reduce vibration, you need to perform shock absorption on the system. However, making overall changes to the entire system may cause some other adverse effects, but for some parts, making corresponding adjustments will not damage the entire system, so vibration treatment of the optical frame is necessary. Utility Model Content
[0004] The purpose of the utility model is to provide a vibration-proof optical frame to solve the problems raised in the above-mentioned background technology.
[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0006] A vibration-proof optical frame comprises a frame outer frame and a lens platform. The frame outer frame is provided with a shock-absorbing component and a connecting rod. The shock-absorbing component is fixedly connected to the frame outer frame, and the shock-absorbing component is used to reduce the vibration of the frame in the horizontal direction. A lens carrier block is provided on the lens platform, and a lens is spirally connected to the lens carrier block. A cooling component is provided on one side of the lens carrier block, and the cooling component is used to absorb the heat on the lens carrier platform. Shock-absorbing blocks are provided at the lower end and the upper end of the lens carrier block, and the shock-absorbing blocks are fixedly connected to the lens carrier block and the frame outer frame. The shock-absorbing blocks are used to reduce the vibration in the vertical direction.
[0007] The above technical solution is adopted, in which a shock-absorbing component and a shock-absorbing block are arranged on the outer frame of the frame. The shock-absorbing component mainly absorbs and reduces vibrations through the damping effect of the components in the shock-absorbing component. Damping refers to the process in which the system gradually weakens or disappears over time when it is subject to external interference or changes in initial conditions. In physics, damping refers to the process of slowing down the vibration or movement of an object. In engineering and control theory, damping refers to the process of reducing system oscillations or shocks. The damping effect slows down the vibration and plays a role in reducing shocks. In addition, the frame is also provided with a cooling component to cool the stage to ensure that the optical performance of the optical elements on the stage is not damaged and can be used normally.
[0008] A further improvement of the technical solution of the utility model is that the cooling assembly includes a heat conducting plate and a cooling box, the heat conducting plate is fixedly connected to the lens table, the cooling box is fixedly connected to the outer frame of the frame, and cooling material is introduced into the cooling box through an external device.
[0009] The above technical solution is adopted, in which the cooling component is provided with a heat conducting plate, and the heat conducting plate material has excellent heat absorption characteristics, which can absorb the heat from various places on the stage, and then the cooling material in the cooling box 12 absorbs the heat on the heat conducting plate, so that the heat absorption can be more uniform, and the uneven heat and cold phenomenon can be prevented from causing damage to the optical components.
[0010] A further improvement of the technical solution of the utility model is that the shock absorbing component includes a spring sheet, an elastic column, and the support column spring sheets are arranged in pairs, a spring is sleeved on the support column, and the spring and the support column are fixedly connected to the frame shell; the elastic column is columnar, one end of the elastic column is fixedly connected to the support column, and the other end is in tangential contact with the lens table.
[0011] The above technical solution is adopted, in which elastic columns and support columns are provided and connected with springs, spring sheets are provided on both sides of the springs, and vibration in the horizontal direction is reduced by providing the elastic columns and support columns.
[0012] A further improvement of the technical solution of the utility model is that the cooling material is a liquid cooling material.
[0013] The above technical solution is adopted, in which the cooling material is in liquid state. When the vibration is transmitted to the liquid, the water molecules in the liquid will vibrate and thus transmit the vibration. The movement between the liquid molecules will generate a force that causes the vibration to be dispersed and absorbed, thereby weakening the vibration. Therefore, when the vibration is transmitted to the shock absorber, it will be doubly weakened, thereby improving the shock absorption effect.
[0014] A further improvement of the technical solution of the utility model is that a cavity is provided inside the shock absorbing block, and the cavity is filled with liquid.
[0015] By adopting the above technical solution, in which the shock absorbing block is provided with a cavity and the cavity is filled with liquid, the damping effect of the entire shock absorber can be improved, thereby reducing the vibration during up and down vibration and improving the stability of the system.
[0016] A further improvement of the technical solution of the utility model is that the elastic column, the support column and the fixing block are all made of rubber.
[0017] The above technical solution is adopted. In this solution, the rubber material has certain characteristics in terms of damping effect. When the rubber material is subjected to external force, it will deform, thereby absorbing and dispersing energy and reducing the amplitude of vibration. This energy absorption and dispersion characteristic has a good shock absorption effect.
[0018] A further improvement of the technical solution of the utility model is that an adjustment mechanism is provided at the lower end of the outer frame of the frame, including a base, a worm gear, a worm, and a handle, the worm gear and the worm are fixedly connected to the base, the connecting rod is fixedly connected to the turbine shaft, the turbine is spirally connected to the worm, and the handle is fixedly connected to the worm.
[0019] By adopting the above technical solution, the rotation adjustment of the frame can be realized by setting a worm gear structure, which can facilitate our adjustment in different situations in actual use.
[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:
[0021] 1. The utility model provides a vibration-proof optical frame, which is provided with a vibration-absorbing block and a vibration-absorbing component. In this scheme, a vibration-absorbing component and a vibration-absorbing block are provided on the outer frame of the frame. The vibration-absorbing component mainly absorbs and reduces vibration through the damping effect of the components in the vibration-absorbing component. In addition, a cooling component is provided on the frame to cool the stage to ensure that the optical performance of the optical elements on the stage is not damaged and can be used normally. The vibration is reduced in both vertical and horizontal directions to improve the vibration-reducing effect.
[0022] 2. The utility model provides an anti-vibration optical frame, in which a cooling component is provided on one side of the lens stage. The cooling component is provided with a heat conducting plate, and the heat conducting plate material has good heat absorption characteristics. The heat from various places on the lens stage can be absorbed, and then the cooling material in the cooling box 12 absorbs the heat on the heat conducting plate. In this way, the heat absorption can be more uniform, and the uneven cold and heat phenomenon can be prevented from causing damage to the optical elements.

DETAILED DESCRIPTION
[0031] The present invention is further described in detail below in conjunction with the embodiments:
[0032] Example 1
[0033] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides an anti-vibration optical frame, including a frame outer frame 1, and a lens platform 2, characterized in that: a shock-absorbing component 3 and a connecting rod 19 are provided on the frame outer frame 1, the shock-absorbing component 3 is fixedly connected to the frame outer frame 1, and the shock-absorbing component 3 is used to reduce the vibration of the frame in the horizontal direction; a lens carrier block 4 is provided on the lens platform 2, and a lens is spirally connected to the lens carrier block 4; a cooling component 5 is provided on one side of the lens carrier block 4, and the cooling component 5 is used to absorb the heat on the lens carrier platform; shock-absorbing blocks 6 are provided at the lower end and the upper end of the lens carrier block 4, and the shock-absorbing blocks 6, the lens carrier block 4 and the frame outer frame 1 are all fixedly connected; the shock-absorbing blocks 6 are used to reduce the vibration in the vertical direction.
[0034] In this embodiment, a shock absorbing component 3 and a shock absorbing block 6 are provided on the frame 1 of the frame. The shock absorbing component 3 mainly absorbs and reduces vibrations through the damping effect of the components in the shock absorbing component 3. Damping refers to the process in which the system gradually weakens or disappears over time when it is subject to external interference or changes in initial conditions. In physics, damping refers to the process of slowing down the vibration or movement of an object. In engineering and control theory, damping refers to the process of reducing system oscillations or shocks. The damping effect is used to slow down the vibration and reduce the shock. In addition, a cooling component is provided on the frame to cool the stage to ensure that the optical performance of the optical elements on the stage is not damaged and can be used normally.
[0035] like Figure 1-5 As shown, in this embodiment, preferably, the shock absorbing component 3 includes a spring sheet 7, an elastic column 8, and a support column 9. The spring sheet 7 is arranged in pairs, and a spring 10 is sleeved on the support column 9. The spring 10 and the support column 9 are both fixedly connected to the frame housing; the elastic column 8 is columnar, and one end of the elastic column 8 is fixedly connected to the support column 9, and the other end is in tangential contact with the lens table 2.
[0036] In the shock-absorbing component 3, when the vibration amplitude is small, the elastic column 8 and the support column 9 often take effect. The elastic column 8 and the support column 9 contract to weaken the vibration through the damping effect. When the vibration amplitude is large, the spring 10 will contract and cooperate with the elastic column 8 and the support column 9 to weaken the vibration.
[0037] Example 2
[0038] like Figure 4 As shown, based on Example 1, the utility model provides a technical solution: preferably, a cavity 13 is provided inside the shock absorbing block 6, and the cavity 13 is filled with liquid.
[0039] In this embodiment, a cavity 13 is provided inside the shock absorbing block 6, and a liquid is provided in the cavity 13. The liquid also has damping. Liquid damping refers to the resistance of obstacles existing in the fluid to the movement of an object. When an object moves in a liquid, the liquid molecules will interact with the surface of the object to generate resistance, thereby slowing down the movement of the object. This resistance is called liquid damping. When the vibration is transmitted to the liquid, the water molecules in the liquid will vibrate and thus propagate the vibration. The movement between the liquid molecules will generate a force that causes the vibration to be dispersed and absorbed, thereby weakening the vibration. Therefore, when the vibration is transmitted to the shock absorber, it will be doubly weakened to improve the shock absorption effect.
[0040] Preferably, the elastic column 8, the supporting column 9 and the fixing block are all made of rubber.
[0041] Rubber material has certain characteristics in terms of damping effect. When rubber material is subjected to external force, it will be more likely to deform, and through deformation, the vibration will be converted into internal energy inside the rubber, thereby absorbing and dispersing energy and reducing the amplitude of vibration. This energy absorption and dispersion characteristic has a good shock absorption effect.
[0042] Example 3
[0043] like Figure 3 , Figure 4 As shown, based on Example 1, the utility model provides a technical solution: preferably, the cooling component 5 includes a heat conductive plate 11 and a cooling box 12, the heat conductive plate 11 is fixedly connected to the lens table 2, the cooling box 12 is fixedly connected to the frame 1, and a cooling material is introduced into the cooling box 12 through an external device.
[0044] In this embodiment, the cooling component is provided with a heat conducting plate. The heat conducting plate material has excellent heat absorption characteristics and can absorb heat from various places on the stage. Then the cooling material in the cooling box 12 absorbs the heat on the heat conducting plate. In this way, the heat absorption can be more uniform, and the uneven heat and cold phenomenon can be prevented from causing damage to the optical elements.
[0045] Preferably, the cooling substance is a liquid cooling substance.
[0046] Liquid cooling materials can not only achieve cooling, but because of the liquid, they can also play a certain shock-absorbing role like the liquid in a shock absorber, thereby improving practicality.
[0047] Example 4
[0048] like Figure 1 , Figure 5 As shown, based on Example 1, the utility model provides a technical solution: preferably, the adjustment mechanism 14 includes a base 15, a worm wheel 16, a worm 17, and a handle 18. The worm wheel 16 and the worm 17 are fixedly connected to the base 15, the connecting rod 19 is fixedly connected to the turbine shaft, the turbine and the worm 17 are spirally connected, and the handle 18 is fixedly connected to the worm 17.
[0049] In this embodiment, the turbine and the worm 17 are spirally connected, so when the worm 17 is rotated, the turbine will rotate, but the worm wheel 16 cannot drive the worm 17 to move, which can achieve the effect of self-locking. A connecting rod 19 is provided on the outer shell of the frame, and the connecting rod 19 is fixedly connected to the turbine, so when we turn the handle 18, we can drive the frame to rotate for direction adjustment.
[0050] The working principle of the anti-vibration optical frame is described in detail below.
[0051] like Figure 1 , Figure 3 , Figure 5 As shown, when the frame encounters vibration during transportation or use, in the horizontal direction, the vibration will be transmitted to the elastic ball and then to the elastic column 8, and then to the spring 10 to reduce the vibration in the horizontal direction. A shock-absorbing block 6 is provided in the vertical direction. The shock-absorbing block 6 is made of rubber, and the internal cavity 13 is filled with coolant. The coolant can increase the damping of the shock absorber on the one hand, and can also have a cooling effect on the other hand. Heat will be generated during the operation and shock absorption process. The heat of the lens stage will be first absorbed by the heat conductive sheet 11, and then the heat will be taken away by the coolant in the cooling box 12. When using, it may be necessary to adjust the direction of the lens. At this time, the handle 18 can be turned to rotate and adjust the outer frame 1 of the frame to adjust the direction of the lens.
[0052] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
