Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Fig. 1 is a three-dimensional perspective structural view of an air shock absorber, which shows a structure that can help those skilled in the art to better understand the present invention. Referring to fig. 1, an embodiment of the present invention is an air damper for vertical damping, which includes an outer shell 1, wherein the outer shell 1 is cylindrical, and a lower portion of the outer shell is a closed cavity, which is called an air damping cavity, in use, in order to form the air damping cavity, a piston 2 is installed inside the outer shell 1, and when an edge of the piston 2 is in close contact with an inner wall of the outer shell 1, the air damping cavity is formed; moreover, in order to adjust the damping rigidity and damping of the damper, the bottom of the outer shell 1 needs to be designed with an air inlet 3 and an air outlet 6, the air inlet 3 and the air outlet are communicated with the air damping cavity, and in cooperation therewith, a closing rod 4 is further installed at the lower portion of the piston 2, and then a closing plug 5 is installed at the end of the closing rod 4, the position of the closing plug 5 is required to correspond to the position of the exhaust port 6, so that the closing plug 5 can be driven by the piston 2 through the closing rod 4 to move up and down, because the closing rod 4 has a certain length, the distance that the piston 2 drives the closing plug 5 to move downwards can only be equal to the length of the closing rod 4, at the moment, the exhaust port 6 is sealed by the closing plug 5, and the gas in the air vibration damping cavity can not be exhausted any more, so that the air compression vibration damping is realized, and based on the principle, the vibration damping rigidity and the damping of the vibration damper can be adjusted by adjusting the length of the closing rod 4; in cooperation with this, a one-way closing device 7 is installed on the air inlet 3 to prevent the air in the air damping chamber from being discharged from the air inlet 3 during the aforementioned process. Preferably, in order to facilitate the application of the shock absorber, the piston 2 is further provided with a piston rod 8, and the upper part of the piston rod 8 is used for directly or indirectly mounting the storage table. By facilitating the close contact of the piston 2 with the inner wall of the outer housing 1, it is preferable to design the cross section of the outer housing 1 and the outer contour of the piston 2 to be circular, i.e., a circular piston 2 and a cylindrical outer housing 1.
In the embodiment, a structure that the piston 3 is matched with the closed outer shell 1 is adopted, a closed air vibration reduction cavity can be formed in the outer shell 1, vertical vibration reduction is realized on an object on a table top by utilizing the compressibility of air, the vibration reduction rigidity and the damping of the vibration reducer can be adjusted by adjusting the air inflow and the air exhaust of the air vibration reduction cavity, the rigidity and the damping of the vibration reducer can be designed according to parameters such as the weight, the height-width ratio and the external load property of the object to be subjected to vibration reduction, the vibration reducer can be matched with a vibration reduction device in the horizontal direction, three-way vibration reduction on the object on the table top is realized, and the manufacturing cost of the air vibration reduction structure is lower compared with that of a rubber vibration reducer.
According to another embodiment of the present invention, the opening area of the air inlet 3 is designed to be larger than the opening area of the air outlet 6, so that when the platform surface moves upward and hangs, air is sucked into the air damping cavity through the large-area air inlet 3 by using the original pressure inside the outer shell 1 and the weight of the object on the platform surface; when the object on the table top and the upper part of the table top move downwards, the air inlet 3 is closed through the one-way closing device, air in the air vibration reduction cavity is exhausted from the small-area exhaust port 6, at the moment, the air cannot be exhausted quickly and completely and can only be exhausted slowly through the small hole, so that the object on the table top can play a role in buffering when moving downwards, until the exhaust port 6 is sealed by the closing plug 5, the closed air vibration reduction cavity is formed again, and vertical vibration reduction is continuously carried out on the object on the table top.
Further, the inventor also specifically designs the structure of the one-way closing device 7 in this embodiment, as shown in fig. 1, the one-way closing device 7 includes a top cover 71, then the top cover 71 is installed on the air inlet cylinder 72, and the air inlet cylinder 72 is placed on the air outlet 6, meanwhile, a plurality of closing blades 9 are also installed on the air outlet 6; the preferred structure of the closing blade 9 is that the air inlet 3 is designed into a regular hexagon, then the closing blade 9 is designed into six triangular blades, and the air inlet 3 is normally closed by the six triangular blades, and when the air flow enters the air damping cavity from the outside, the closing blade 9 is opened, so that the closing blade 9 can be made of flexible material.
Based on the above embodiments of the present invention, the damper utilizes the principle that gas has compressibility, and the volume of gas can be changed by external force. Under otherwise constant conditions, the volume of the pressurized gas becomes smaller and the volume of the depressurized gas becomes larger. This is due to the fact that the spacing between the molecules of the gas is larger than that of the liquid and solid. The spacing between gas molecules is due to the repulsive and attractive forces between the gas molecules. By utilizing the principle, the vibration damping effect can be realized. Namely, the air vibration damping cavity of the vibration damper can play a certain vibration damping role when being closed, and when an object with the function is suspended and falls to the ground, the vibration damper can play a better buffering role than when being closed.
As mentioned above, by adjusting the length of the closing rod 4 and the sizes of the air inlet 3 and the air outlet 6, parameters such as damping and rigidity of the shock absorber can be adjusted, and the application range is wider; meanwhile, the outer shell 1 of the shock absorber is of a cylindrical structure, and a spring structure can be sleeved outside the outer shell, so that the shock absorption capacity of the whole device is adjusted, and the shock absorption effect is better achieved.
