Description

Technical Field

[0001] This utility model relates to the field of optical engineering technology, and in particular to an optical platform support device inside a vacuum container. Background Technology

[0002] A vacuum container is a sealed container with an internal pressure lower than the external atmospheric pressure. The optical platform support device inside the vacuum container is used to support the optical platform in the vacuum environment and ensure that the optical platform remains stable.

[0003] Existing vacuum container optical platform support devices utilize rubber vibration damping pads placed between the optical platform and the support device, and between the platform and the vacuum container. When vibrations are transmitted, the rubber damping pads undergo elastic deformation, absorbing and dissipating vibration energy, thus buffering and reducing shock. However, under heavy loads, the rubber damping pads deform significantly and cannot fully return to their original shape after unloading. This causes changes in the height of the optical platform, affecting its levelness and stability, and consequently the accuracy of optical experiments. Existing technologies improve the load-bearing capacity of the rubber damping pads by adding specific reinforcing agents to natural rubber and using high-strength neoprene rubber varieties, reducing deformation under heavy loads. However, neoprene rubber gradually ages when exposed to external environments such as high temperature, high humidity, and strong ultraviolet radiation over a long period. Aged neoprene rubber exhibits surface cracking, hardening, and loss of elasticity, thus affecting the normal use of the damping pads. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides an optical platform support device inside a vacuum container, which aims to improve the problem that neoprene rubber will gradually age when exposed to the external environment for a long time. The aged neoprene rubber will exhibit surface cracking, hardening, and loss of elasticity, thereby affecting the cushioning performance of the vibration isolation pad.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an optical platform support device inside a vacuum container, comprising a table body, hollow cylinders fixedly connected to the top of the table body near the four corners, support columns fixedly connected to the bottom wall inside the hollow cylinders, multiple sliding grooves equidistantly formed around the inner wall of the support columns, multiple serrated blocks fixedly connected equidistantly to the right side of the inner wall of the sliding grooves, an elongated external toothed groove plate slidably connected inside the sliding grooves, a fixing spring fixedly connected to the left side of the inner wall of the sliding grooves, a spring frame fixedly connected to the top of the elongated external toothed groove plate, a hollow placement plate fixedly connected to the top of the spring frame, and a clamping mechanism installed at the bottom of the table body for clamping vacuum containers of different sizes.

[0006] As a further description of the above technical solution:

[0007] The clamping mechanism includes a motor mounted on the bottom of the table. A gear is fixedly connected to the output end of the motor. Slide rails are fixedly connected to the front and rear sides of the inner wall of the hollow placement plate. Sliding blocks are slidably connected to the outer wall of the slide rails. A rack is fixedly connected to an adjacent side of the outer wall of the sliding block. The rack meshes with the gear. A fixing plate is fixedly connected to the top of the rack. An anti-slip plate is fixedly connected to the top of the right fixing plate. A hollow block is fixedly connected to the top of the left fixing plate. A threaded rod is threaded inside the hollow block. A semi-circular block is slidably connected to the right end of the outer wall of the threaded rod. An internally threaded rotating block is rotatably connected inside the hollow block.

[0008] As a further description of the above technical solution:

[0009] A screw is threadedly connected to the front side of the outer wall of the hollow placement plate, and a warning sign is threadedly connected to the outer wall of the screw.

[0010] As a further description of the above technical solution:

[0011] A screw is threadedly connected to the right side of the outer wall of the semi-circular block, and an anti-slip pad is threadedly connected to the outer wall of the screw.

[0012] As a further description of the above technical solution:

[0013] The outer left side of the hollow placement plate is threaded with screw three, and the outer wall of screw three is threaded with hook.

[0014] As a further description of the above technical solution:

[0015] A hollow box is fixedly connected to the bottom of the table, and a drawer is slidably connected inside the hollow box.

[0016] As a further description of the above technical solution:

[0017] A handle is fixedly connected to the front side of the outer wall of the drawer, and a protective sleeve is fixedly connected to the outer wall of the handle.

[0018] As a further description of the above technical solution:

[0019] The bottom of the table is fixedly connected with multiple short posts at equal intervals, and the bottom of each short post is fixedly connected with a foot pad.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, when an external force is applied to the hollow placement plate, the force is transmitted to the spring frame, causing it to move downward and push the elongated outer toothed plate to slide in the groove. The toothed groove engages with the sawtooth block, generating resistance and providing initial buffering force. As the elongated outer toothed plate continues to slide, it compresses the fixed spring, achieving secondary buffering and providing stable support for the optical platform. This avoids the problem that neoprene rubber will gradually age due to long-term exposure to the external environment, and the aged neoprene rubber will exhibit surface cracking, hardening, and loss of elasticity, thus affecting the buffering performance of the vibration isolation pad.

[0022] 2. In this utility model, after the motor is started, it drives the gear to rotate and meshes with the rack, causing the rack to move along the slide rail. The fixed short plate at the top of the rack moves accordingly, and the anti-slip plate fits against the outer wall of the vacuum container to fix the container. At the same time, rotating the threaded rod can further adjust the semi-circular block to adapt to the clamping of vacuum containers of different sizes and shapes, thereby enabling more precise adjustment of the clamping force on the vacuum container and ensuring that the vacuum container is stably clamped between the anti-slip plate and the semi-circular block for fixation.

[0030] 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.

[0031] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of an optical platform support device inside a vacuum container, comprising a table body 1. Hollow cylinders 4 are fixedly connected to the top of the table body 1 near its four corners. Support columns 21 are fixedly connected to the bottom wall inside the hollow cylinders 4. Multiple sliding grooves 22 are equidistantly formed on the inner wall of the support columns 21. Multiple serrated blocks 19 are equidistantly fixed to the right side of the inner wall of the sliding grooves 22. An elongated external toothed plate 18 is slidably connected inside the sliding grooves 22. A fixing spring 20 is fixedly connected to the left side of the inner wall of the sliding grooves 22, serving as a secondary buffer for force dissipation. A spring is fixedly connected to the top of the elongated external toothed plate 18. A hollow placement plate 3 is fixedly connected to the top of the spring frame 17. A clamping mechanism 2 is installed at the bottom of the table body 1. The clamping mechanism 2 is used to clamp vacuum containers of different sizes. A screw 5 is threadedly connected to the front side of the outer wall of the hollow placement plate 3. A warning sign 6 is threadedly connected to the outer wall of the screw 5. The warning sign 6 can remind the staff of routine precautions during work to reduce the probability of accidents. A screw 7 is threadedly connected to the right side of the outer wall of the semi-circular block 207. An anti-slip pad 8 is threadedly connected to the outer wall of the screw 7. The anti-slip pad 8 can increase the contact area between the anti-slip pad 8 and the clamped vacuum container to prevent slippage.

[0032] Specifically, when an external force is applied to the hollow placement plate 3, the hollow placement plate 3 transmits the force to the spring frame 17 connected to it at the bottom. The spring frame 17, under this force, moves downwards and transmits the force to the elongated external toothed plate 18. As the elongated external toothed plate 18 slides within the groove 22 on the inner wall of the support column 21, the teeth on the elongated external toothed plate 18 engage with the serrated block 19 on the right side of the inner wall of the groove 22, causing them to fall sequentially. This engagement generates resistance, hindering the rapid sliding of the elongated external toothed plate 18, thus providing initial buffering against the force applied to the hollow placement plate 3. As the elongated external toothed plate 18 continues to slide within the groove 22, when the engagement of the serrated block 19 with the elongated external toothed plate 18 further compresses the fixed spring 20 on the left side of the inner wall of the groove 22... It will act as a secondary buffer. The fixed spring 20 is elastic. When it is squeezed, it will deform and store elastic potential energy. It will generate an elastic force opposite to the movement direction of the elongated outer toothed plate 18. This elastic force will offset part of the impact force that continues to be transmitted, further consume energy, and achieve a second buffer against the impact force, so as to provide a more stable support environment for the optical platform. The outer wall of the hollow placement plate 3 is threaded with screw 5. The outer wall of screw 5 is threaded with a warning sign 6. The warning sign 6 can remind the staff of the routine precautions during work to reduce the probability of accidents. The outer wall of the semi-circular block 207 is threaded with screw 7. The outer wall of screw 7 is threaded with an anti-slip pad 8. The anti-slip pad 8 can enhance the contact area between the anti-slip pad 8 and the clamping vacuum container to prevent slippage.

[0033] Reference Figure 1 , Figure 2 and Figure 5The clamping mechanism 2 includes a motor 201, which is installed at the bottom of the table body 1. A gear 202 is fixedly connected to the output end of the motor 201. Slide rails 203 are fixedly connected to the front and rear sides of the inner wall of the hollow placement plate 3. Sliding blocks 206 are slidably connected to the outer wall of the slide rails 203. A rack 211 is fixedly connected to each adjacent side of the outer wall of the sliding blocks 206. The rack 211 meshes with the gear 202. Turning on the motor 201 drives the gear 202 at the output end to rotate. When the gear 202 rotates, it meshes with the racks 211 on both sides, thereby driving the racks 211 to move. A fixing plate 204 is fixedly connected to the top of each rack 211. An anti-slip plate 205 is fixedly connected to the top of the right fixing plate 204, and a fixing plate 205 is fixedly connected to the top of the left fixing plate 204. A hollow block 208 is fixedly connected to the top of the fixed short plate 204. A threaded rod 210 is threadedly connected inside the hollow block 208. A semi-circular block 207 is slidably connected to the right end of the outer wall of the threaded rod 210. The distance of the semi-circular block 207 can be adjusted by rotating the threaded rod 210. An internally threaded rotating block 209 is rotatably connected inside the hollow block 208. A screw 15 is threadedly connected to the left side of the outer wall of the hollow placement plate 3. A hook 16 is threadedly connected to the outer wall of the screw 15. The hook 16 can be used to hang tools for daily use and cleaning for future use. A hollow box 12 is fixedly connected to the bottom of the table body 1. A drawer 11 is slidably connected inside the hollow box 12. The drawer 11 can be used to store tools for daily use and maintenance for future use.

[0034] Specifically, by turning on the motor 201, the output gear 202 is driven to rotate. Since the gear 202 is meshed with the rack 211, and the rack 211 is slidably connected to the slide rail 203 on the inner wall of the hollow placement plate 3 through the sliding block 206, the rotation of the gear 202 will cause the rack 211 to move along the slide rail 203, thereby driving the fixed short plate 204 to move. The anti-slip plate 205 on the top of the right fixed short plate 204 can fit and fix against one side of the outer wall of the clamped vacuum container. Then, the threaded rod 210 is rotated. The semi-circular block 207, which is slidably connected to the right end of the outer wall, can be further adjusted to clamp vacuum containers of different sizes and shapes. The outer left side of the hollow placement plate 3 is threaded with screw 15, and the outer wall of screw 15 is threaded with hook 16. Hook 16 can be used to hang tools for daily use and cleaning for future use. The bottom of the table body 1 is fixedly connected with a hollow box 12, and a drawer 11 is slidably connected inside the hollow box 12. Drawer 11 can be used to store tools for daily use and maintenance for future use.

[0035] Reference Figure 1 and Figure 2A handle 9 is fixedly connected to the front side of the outer wall of the drawer 11. The handle 9 facilitates the opening and closing of the drawer 11 by the staff. A protective cover 10 is fixedly connected to the outer wall of the handle 9. Multiple fixed short posts 14 are fixedly connected at equal intervals to the bottom of the table body 1. Foot pads 13 are fixedly connected to the bottom of the fixed short posts 14. The foot pads 13 can absorb the vibration force during the operation of the equipment and achieve a further cushioning effect.

[0036] Specifically, a handle 9 is fixedly connected to the front side of the outer wall of the drawer 11. The handle 9 facilitates the opening and closing of the drawer 11 by the staff. A protective cover 10 is fixedly connected to the outer wall of the handle 9. Multiple fixed short posts 14 are fixedly connected at equal intervals to the bottom of the table body 1. Foot pads 13 are fixedly connected to the bottom of the fixed short posts 14. The foot pads 13 can absorb the vibration force during the operation of the equipment and achieve a further cushioning effect.

[0037] Working principle: When an external force is applied to the hollow placement plate 3, the hollow placement plate 3 will transfer the force to the spring frame 17 connected to it at the bottom. After being subjected to force, the spring frame 17 will move downward and transfer the force to the elongated external toothed plate 18. During the sliding process of the elongated external toothed plate 18 in the slide groove 22 on the inner wall of the support column 21, the teeth on the elongated external toothed plate 18 and the sawtooth block 19 on the right side of the inner wall of the slide groove 22 will engage with each other and fall off in sequence. This engagement will generate a certain resistance, hindering the rapid sliding of the elongated external toothed plate 18, thereby providing the initial buffer for the force applied to the hollow placement plate 3. As the elongated external toothed plate 18 continues to slide in the slide groove 22, when the sawtooth block 19 and the elongated external toothed plate engage with each other, the teeth on the elongated external toothed plate 18 will engage with each other and fall off in sequence. This engagement will generate a certain resistance, hindering the rapid sliding of the elongated external toothed plate 18, thereby providing the initial buffer for the force applied to the hollow placement plate 3. As the elongated external toothed plate 18 continues to slide in the slide groove 22, when the sawtooth block 19 engages with the elongated external toothed plate 18, the teeth on the elongated external toothed plate 18 will engage with each other and fall off in sequence. The cooperation of plate 18 allows the elongated external toothed plate 18 to further compress the fixed spring 20 on the left side of the inner wall of the slide groove 22, which will play a secondary buffering role. The fixed spring 20 is elastic and will deform and store elastic potential energy when compressed. It will generate an elastic force opposite to the movement direction of the elongated external toothed plate 18. This elastic force will offset part of the impact force that continues to be transmitted, further consume energy, and achieve a second buffering of the impact force, thereby providing a more stable support environment for the optical platform. This avoids the problem that chloroprene rubber will gradually age due to long-term exposure to the external environment. After aging, chloroprene rubber will have surface cracks, harden, and lose elasticity, which will affect the buffering performance of the vibration isolation pad.

[0038] By turning on the motor 201, the output gear 202 is driven to rotate. Since the gear 202 is meshed with the rack 211 and the rack 211 is slidably connected to the slide rail 203 on the inner wall of the hollow placement plate 3 through the sliding short block 206, the rotation of the gear 202 will cause the rack 211 to move along the slide rail 203, thereby driving the fixed short plate 204 to move. The anti-slip plate 205 on the top of the right fixed short plate 204 can fit and fix with one side of the outer wall of the clamped vacuum container. Then, by rotating the threaded rod 210, the semi-circular block 207 slidably connected to the right end of the outer wall can be further adjusted to clamp vacuum containers of different sizes and shapes, so as to more finely adjust the clamping force of the vacuum container and ensure that the vacuum container is stably clamped between the anti-slip plate 205 and the semi-circular block 207 for fixation.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
