Description

Technical Field

[0001] This invention relates to the field of vibration isolation platform technology, specifically to a vibration isolation platform for precision instruments. Background Technology

[0002] Precision instruments are extremely sensitive to vibration; even minor mechanical vibrations can lead to measurement errors or a decline in equipment performance. Traditional vibration isolation platforms typically use threaded connections to fix the feet, which are the main supports for filtering ground vibrations.

[0003] In the existing technology, the vibration isolation platform uses adjustable feet. However, in order to make the vibration isolation platform match the frequency of the vibration isolator, it is necessary to adjust according to the weight of the instrument on the platform. Therefore, the feet need to be replaced according to the type of instrument. However, when replacing the existing feet, one corner of the platform needs to be lifted to a space where the threaded rod can be completely disassembled. This foot replacement is too cumbersome and inconvenient. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a vibration isolation platform for precision instruments, which solves the problem of convenient replacement of the platform's feet. The quick-release adjustment components and fixing mechanism enable rapid maintenance and replacement of the feet, and facilitate the movement and placement of the platform itself.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a precision instrument vibration isolation platform, comprising a platform body and a lower support, wherein the lower end of the lower support is provided with a foot, and the upper end of the foot is connected to a quick-release adjustment component; a placement groove is provided on the outer side of the lower end of the lower support, and a locking groove is connected to the upper end of the placement groove; the quick-release adjustment component is located in the placement groove and its upper end is matched and engaged with the locking groove; a fixing mechanism is provided on the outer side of the lower end of the lower support, and the fixing mechanism is matched and correspondingly arranged with the quick-release adjustment component. The quick-release adjustment component facilitates the replacement and movement of the lower foot of the lower support, and makes it convenient to adjust the foot according to the platform body.

[0006] Furthermore: the quick-release adjustment assembly includes a retaining plate, a threaded rod, and a movable cylinder. The retaining plate is matched with a retaining groove. The threaded rod is fixed to the lower end of the retaining plate, and a rotatable caster is fixed to the lower end of the threaded rod. The caster is located inside the foot pad. The movable cylinder is fixed to the upper end of the foot pad. An adjustment knob is threadedly connected to the threaded rod between the movable cylinder and the retaining plate. The rotation of the adjustment knob controls the raising and lowering of the movable cylinder, thereby adjusting the movement and fixed placement of the platform body and the lower support as a whole.

[0007] Furthermore, the quick-release adjustment assembly also includes a spring located inside the movable cylinder, with its upper end abutting against the inner wall of the movable cylinder and its lower end fixed to the lower end of the threaded rod. When the adjustment knob is moved upward, the spring pushes the movable cylinder upward, causing the caster wheel to support the overall platform.

[0008] Furthermore: the fixing mechanism includes a cover plate and a fixing button. The cover plate covers the upper part of the slot and the placement slot, and a fixing hole is provided on the cover plate. The fixing button cooperates with the fixing hole to limit and fix the position.

[0009] Furthermore, a limiting plate is fixed to the inner side of the cover plate, and the limiting plate is matched with the threaded rod to improve the stability of the threaded rod.

[0010] Furthermore, the outer wall of the adjustment knob is fixed with multiple protrusions, and the protrusions are equally spaced.

[0011] This invention provides a vibration isolation platform for precision instruments. Compared with existing technologies, it has the following advantages:

[0012] This precision instrument vibration isolation platform features a movable cylinder that can be raised and lowered via an adjustment knob, allowing for quick switching between casters and feet for easy movement and fixation. The clamping plate and threaded rod utilize a slotted fixing mechanism for quick disassembly and assembly, facilitating maintenance or replacement of different support components. Suitable for various ground environments, it allows for flexible switching between casters and feet in either moving or fixed modes, enhancing its versatility. The overall design is simple, with tightly integrated components ensuring long-term stability and durability. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figure 1-6 This invention provides a technical solution: a vibration isolation platform for precision instruments; specifically, it consists of a platform body 1 and a lower support 2. A foot 3 is provided at the lower end of the lower support 2, and a quick-release adjustment assembly is provided at the upper end of the foot 3. A placement groove 4 is provided on the outer side of the lower end of the lower support 2, and a slot 5 is provided at the upper end of the placement groove 4. The placement groove 4 and the slot 5 are connected. The quick-release adjustment assembly includes a locking plate 8, a threaded rod 7, and a moving cylinder 6. An adjustment knob 9 is threadedly connected between the locking plate 8 and the moving cylinder 6. The position of the moving cylinder 6 is controlled by the position of the adjustment knob 9. A rotatable universal wheel 10 is fixed at the lower end of the threaded rod 7. The universal wheel 10 is located inside the foot 3. The locking plate 8 is matched with the slot 5. A fixing mechanism is provided on the outer side of the lower end of the lower support 2. The fixing mechanism is matched with the quick-release adjustment assembly. After the fixing mechanism is disassembled outward, the locking plate 8 and the threaded rod 7 can be directly removed from the slot 5 and the placement groove 4 for replacement, which facilitates the adjustment of the corresponding support.

[0022] The quick-release adjustment assembly also includes a spring 11, which is located inside the movable cylinder 6. The lower end of the spring 11 is fixedly connected to the lower end of the threaded rod 7, and the upper end of the spring 11 is set against the upper end of the interior of the movable cylinder 6. When the adjustment knob 9 moves upward, the spring 11 pushes the movable cylinder 6 upward. At this time, it is supported by the caster wheel 10, which makes it easy to move the whole assembly.

[0023] The fixing mechanism includes a fixing button 15 and a cover plate 12 that are threadedly rotated on the outer side wall of the lower end of the lower bracket 2. When the card plate 8 is placed in the card slot 5, the cover plate 12 can cover the card slot 5 and the upper part of the placement slot 4. A fixing hole 14 is provided on the cover plate 12, which matches and corresponds to the fixing button 15. A limit plate 13 is fixed to the inner end of the cover plate 12. The limit plate 13 is matched and set with the threaded rod 7. After the fixing button 15 passes through the fixing hole 14, it rotates upward. The fixing button 15 can be limited and fixed by misaligning with the fixing hole 14. The cover plate 12 prevents the card plate 8 and the threaded rod 7 from moving.
