Description

Technical Field

[0001] This utility model relates to the field of anti-vibration base technology, specifically to an anti-vibration base without pressure blocks. Background Technology

[0002] Industrial equipment, such as machine tools, fans, compressors, and generator sets, generates significant vibrations during operation. Using a non-blocking anti-vibration base can reduce the impact of vibrations on the equipment itself and the surrounding environment.

[0003] In the prior art, for example, Chinese Patent No. CN210318299U discloses a steel plate type shockproof base for an integrated circuit cleanroom, including a support plate. The lower end of the support plate is connected to several evenly distributed control devices. The control devices include positioning posts, support posts, triangular bases, protective shells, positioning rings, deformation shapes, and pressure-resistant seats. The positioning posts are cylindrical in shape, and a columnar groove is opened in the middle of the bottom surface of one end of the cylinder. Three support posts are evenly arranged in the groove of the positioning posts.

[0004] The aforementioned device primarily uses deformable elastic elements to buffer the support plate. However, in daily use, the device lacks damping properties. This lack of damping means that after absorbing vibration energy, the device cannot effectively convert it into heat or other forms of energy dissipation. When the equipment experiences continuous vibration, the elastic elements will continuously compress and expand. Due to the lack of damping, this reciprocating motion may continue for a considerable period, significantly reducing the vibration reduction effect. The equipment's vibration may not be controlled in a timely and effective manner, and its impact on the equipment itself and the surrounding environment remains significant. Therefore, we propose a pressure-block-free vibration-damping base to address these issues. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] A non-blocking shockproof base includes a base body with multiple installation chambers at its bottom. Each installation chamber houses a support assembly, which includes multiple support seats. A receiving platform is fixedly connected to the top of each support seat. Multiple arc-shaped seats are fixedly connected around the support seats, each arc-shaped seat having an arc-shaped chamber inside. Multiple connecting cylinders are fixedly connected to both ends of the inner wall of each arc-shaped chamber. Each connecting cylinder contains a return spring, and an arc-shaped rod is sleeved inside the return spring. An oil chamber is formed between the arc-shaped seats and the support seats. Multiple first connecting holes are provided on the left and right sides of the support seats to facilitate oil flow, and multiple second connecting holes are provided on the front and rear sides of the support seats.

[0008] Preferably, the plurality of mounting chambers are evenly distributed on the base surface, and the plurality of support seats are respectively placed in the plurality of mounting chambers.

[0009] Preferably, a rubber pad is installed on the top of the receiving platform, and a buffer pad is fixedly connected to the top of the receiving platform.

[0010] Preferably, the plurality of arc-shaped seats are evenly distributed around the axis of the support seat, and the plurality of connecting cylinders are evenly distributed along the length direction of the arc-shaped seats.

[0011] Preferably, the two ends of the arc-shaped rod are fixedly connected to the bottom of the inner cavity of the two connecting cylinders, and the arc-shaped rod is composed of a plurality of connecting seat arrangement assemblies.

[0012] Preferably, rubber seats are fixedly connected to the end faces of the plurality of connecting seats that are close to each other, and the plurality of rubber seats are fixed to each other by a pull wire.

[0013] Preferably, the oil chamber is filled with hydraulic oil.

[0014] Preferably, the first connecting hole and the second connecting hole are evenly distributed along the edge of the support base, and the first connecting hole and the second connecting hole are staggered.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] In this invention, the base body has evenly distributed mounting chambers at its bottom, housing built-in support components. The support platform at the top is equipped with rubber pads and buffer pads to enhance the cushioning effect. The arc-shaped seats around the support body contain return springs and arc-shaped rods. The arc-shaped rods are composed of connecting seats, and the rubber seats at the ends of the connecting seats are fixed by pull wires. When the base body is subjected to force, the arc-shaped seats are compressed, and the springs and arc-shaped rods deform, providing basic cushioning and limiting excessive deformation.

[0017] The oil chamber between the arc-shaped seat and the support seat is filled with hydraulic oil, and the first and second connecting holes on both sides of the support seat are staggered. The deformation of the arc-shaped seat compresses the hydraulic oil, causing it to flow in the connecting holes and the chamber, generating a damping effect. The friction between the oil flow and the wall surface and between the oil flows increases with speed, applying a damping force to the base body, and the pressure change of the oil also prevents the arc-shaped seat from deforming.

[0018] This dual buffering mechanism allows the base to better absorb and disperse energy when subjected to external impacts. Oil damping force and pressure changes suppress deformation of the curved base, making the base more stable and reducing swaying and deformation. Evenly distributed support components allow the base to withstand forces in all directions, improving overall stability and reliability. Compared to bases protected only by elastic elements, this shock-absorbing base offers superior shock protection, adapting to complex environments and greater external impacts, providing more reliable shock protection for equipment.

[0026] 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.

[0027] Example: Figures 1-6As shown, this utility model provides a non-blocking shockproof base, including a base body 1. Multiple installation chambers 101 are formed at the bottom of the base body 1 and are evenly distributed on the base surface. Each installation chamber 101 contains a support assembly 2, which includes multiple support seats 201, each placed within one of the installation chambers 101. A receiving platform 202 is fixedly connected to the top of each support seat 201, with a rubber pad and a buffer pad 203 fixedly connected to the top of the receiving platform 202. Multiple arc-shaped seats 204 are fixedly connected around the support seat 201 and are evenly distributed around its axis. Each arc-shaped seat 204 has an arc-shaped chamber 205 inside, with multiple connecting cylinders 206 fixedly connected to both ends of the inner wall of the arc-shaped chamber 205. The connecting cylinders 206 are evenly distributed along the length of the arc-shaped seat 204. The base is evenly distributed. The connecting cylinder 206 contains a return spring 208. The return spring 208 is fitted with an arc-shaped rod 207. The two ends of the arc-shaped rod 207 are fixedly connected to the bottom of the inner cavity of the two connecting cylinders 206 respectively. The arc-shaped rod 207 is composed of multiple connecting seats 209. The end faces of the multiple connecting seats 209 that are close to each other are fixedly connected to rubber seats 210. The multiple rubber seats 210 are fixed to each other by a pull line 211. When the base body 1 moves under force, the base body 1 of the anti-vibration base without pressure block moves under force, first squeezing the arc-shaped seat 204. The return spring 208 inside the arc-shaped seat 204 and the arc-shaped rod 207 composed of multiple connecting seats 209 will deform. The connecting seats 209 will be misaligned. During this process, the multiple rubber seats 210 are fixed to each other by a pull line 211, which plays a certain role in buffering and limiting excessive deformation, and provides basic buffering force.

[0028] Furthermore, an oil chamber 212 is formed between the arc-shaped seat 204 and the support seat 201, and the oil chamber 212 is filled with hydraulic oil 213. Multiple first connecting holes 214 are provided on the left and right sides of the support seat 201 to facilitate the flow of hydraulic oil, and multiple second connecting holes 215 are provided on the front and rear sides of the support seat 201. The first connecting holes 214 and second connecting holes 215 are evenly distributed along the edge of the support seat 201, and are staggered. When the arc-shaped seat 204 deforms, it will squeeze the hydraulic oil 213 in the oil chamber 212, and the hydraulic oil 213 flows out through the first connecting holes 214. The hydraulic oil 213 moves to the other side within the second connecting hole 215 and flows within the cavity. This flow generates a damping effect. During the flow of the hydraulic oil 213 within the connecting hole and the cavity, the friction between the oil flow and the wall surface and between the oil flows generates a force that hinders the deformation of the arc-shaped seat 204. This friction increases with the increase of the oil flow velocity, thereby applying a damping force to the base body 1. During the flow of the hydraulic oil 213, the pressure change of the oil also helps prevent the arc-shaped seat 204 from deforming. Compared with the existing method of using only elastic elements for protection, its base has better shock absorption and protection capabilities and is more stable.

[0029] Working principle: When the base body 1 of the anti-vibration base without pressure block is moved under force, it first squeezes the arc-shaped seat 204. The return spring 208 inside the arc-shaped seat 204 and the arc-shaped rod 207 composed of multiple connecting seats 209 will deform. The connecting seats 209 will be misaligned. During this process, multiple rubber seats 210 are fixed to each other by the pull wire 211, which plays a certain role in buffering and limiting excessive deformation.

[0030] Simultaneously, the hydraulic oil 213 filling the oil chamber 212 between the arc-shaped seat 204 and the support seat 201 is compressed due to the deformation of the arc-shaped seat 204. The hydraulic oil 213 moves from multiple first connecting holes 214 on the left and right sides and multiple second connecting holes 215 on the front and rear sides of the support seat 201 to the other side. The flow of hydraulic oil 213 in the chamber generates a damping effect. Specifically, due to the friction between the oil flow and the wall surface and between the oil flows, a force is generated that hinders the deformation of the arc-shaped seat 204. This friction increases with the increase of the oil flow velocity, thereby applying a damping force to the base body 1. During the flow of hydraulic oil 213, the pressure change of the oil also helps to prevent the arc-shaped seat 204 from deforming.

[0031] This base not only has an elastic buffer structure composed of a return spring 208 and an arc-shaped rod 207, but also a damping buffer effect of hydraulic oil 213. This dual buffering mechanism allows the base to better absorb and disperse energy when subjected to external impacts, improving its shock absorption and protection capabilities. The damping force and pressure changes generated by the hydraulic oil 213 during its flow within the connecting holes and chambers effectively suppress the deformation of the arc-shaped seat 204, making the base more stable during operation and less prone to excessive shaking or deformation. The base body 1 has multiple evenly distributed mounting chambers 101 at its bottom, each containing a support component 2, enabling the base to evenly bear forces from all directions, improving overall stability and reliability. Compared to existing bases that only use elastic elements for protection, this shock-absorbing base without pressure blocks has better shock absorption and protection capabilities, and can adapt to more complex working environments and greater external impacts.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
