Description

TECHNICAL FIELD

[0001] The utility model relates to shock absorbing support structure technical field, concretely is adaptive multidirectional adjustment shock absorbing support structure. BACKGROUND

[0002] A shock absorbing support structure is a device used to reduce the impact of vibrations and shocks. Its main purpose is to absorb and dissipate dynamic loads applied to the structure, reducing the impact of vibrations on the structure, thereby improving the safety and service life of equipment. Shock absorbing support structures are widely used in industrial machinery to cope with adverse effects caused by external factors such as earthquakes, wind, and mechanical vibrations. The structure is usually composed of multiple components, including shock absorbers, springs, and support rods, etc., through reasonable design and layout, to ensure that it can effectively reduce the shock in different directions and different types of vibration.

[0003] The patent with publication number CN219197992U discloses a shock absorbing structure for mechanical engineering support, including a box body, a lifting plate, and a buffer assembly. The lifting plate is set inside the box body and can be lifted along the box body. The buffer assembly includes a first guide rod and two symmetrically arranged buffers. The first guide rod is set inside the box body and is parallel to the bottom surface of the box body. The buffer includes a support plate, a sliding block, and a buffer spring. One end of the support plate is rotationally connected to the middle part of the lifting plate, and the other end is rotationally connected to the sliding block. The sliding block is sleeved on the first guide rod and can freely slide along the axial direction of the first guide rod. The buffer spring is sleeved on the first guide rod, with one end connected to the sliding block and the other end connected to the box body. The utility model can achieve shock absorption in both horizontal and vertical directions, greatly improving the buffering and shock absorbing effect.

[0004] The above-mentioned prior art in the specific use process, when the mechanical equipment produces the vertical direction's vibration, the up-down movement of the lifting plate will cause the sliding block to slide on the first guide rod, and then convert the vertical direction's vibration into the horizontal direction's vibration. The buffer spring corresponding to the sliding block plays an effective buffering role. When the mechanical equipment produces horizontal vibration, the lifting plate will also move horizontally accordingly, and drive the sliding block to move horizontally on the guide rod, thereby achieving shock absorption. However, the horizontal direction shock absorption of this technology has direction fixity, and can only play a shock absorbing effect when the lifting plate is subjected to a force along the axial direction of the first guide rod, which significantly limits its adaptability and overall shock absorbing performance. In view of the limitations of the above-mentioned prior art, we propose an adaptive multidirectional adjustment shock absorbing support structure. This structure aims to overcome the direction fixity problem of horizontal direction shock absorption in the prior art, and through a multidirectional adjustment mechanism, it can effectively adapt to various vibration conditions, thereby greatly improving the shock absorbing effect.
