When in use, a user connects the support 2 with a corresponding object to be supported, such as a table (for convenience, the following description uses the table), and abuts against the bottom surface of the foot base 1.

Specifically, when the table is vibrated by collision, for example, a pressure is applied to the table, the pressure is transmitted to the support 2 and presses the support 2 to move downwards, in the process, since the air chamber 10 is isolated from the outside, the air mass in the air chamber 10 is not changed, but the space of the air chamber 10 is reduced due to the downward movement of the support 2, so that the volume of the air is reduced, and the air pressure in the air chamber 10 is increased, that is, the thrust (air pressure reaction force) generated by the air pressure in the air chamber 10 is equal to the pressure of the air pressure from the outside, the total acting force of the table on the support 2, the gravity of the table and the pressure applied to the table.

In the whole process, because the support 2 needs to move downwards to overcome the thrust generated by the indoor air pressure, namely, in the process that the support 2 moves downwards, the air pressure reaction force in the air chamber 10 can support the pressing block 20 of the support 2 to delay the downward movement speed of the support 2, and the downward movement speed of the support 2 is buffered, namely the action of buffering the pressure applied to the table; when the pressure applied to the table is removed, the reaction force of the air pressure in the air chamber 10 drives the support 2 to push the table to return to the original position, so that the vibration can be reduced.

To sum up, the air pressure foot pad consists of a foot base 1, a support 2 and a sealing ring 3, a pressing block 20 on the support 2 and an air chamber 10 on the foot base 1 form a closed air pressure cavity through the sealing ring 3, and by utilizing the principle of tightness, when the outside applies pressure to the support, equal air pressure reaction force can be generated in the air chamber to the support, so that the force applied to the support is balanced; for example, in the process of pushing the support 2 and returning to the original position by the pushing force (air pressure reaction force) generated by the downward movement of the extrusion support 2 and the air pressure in the air chamber 10, the air pressure cavity is gradually reduced or gradually increased, so that the downward movement of the support 2 and the upward movement of the support 2 are buffered, namely, the air pressure foot pad has the buffering and shock-absorbing effects; the air pressure foot pad realizes buffering and shock absorption by utilizing the strength of air pressure, and the thrust generated by destroying the air pressure of the air chamber 10 needs very large pressure, so that the impact resistance, namely the bearing capacity, of the air pressure foot pad is stronger compared with a spring; on the other hand, compared with a spring, the pneumatic foot pad is not easy to corrode and age, and has longer service life.

With reference to the formula: pV ═ nRT, the krebs equation, i.e., the equation of state for an ideal gas, where P is the gas pressure, V is the gas volume, n is the amount of material of the gas, T is the thermodynamic temperature of the system, and R is a proportionality constant, where n and R are constant quantities, so that the smaller V, the larger P, without taking T into account.

the design that the pressing block 20 is in transition fit connection with the air chamber 10 can ensure that when the support 2 is stressed, the stress can be uniformly transmitted to the side wall of the air chamber 10 of the foot base 1 through the pressing block 20, so that the pressing block 20 is not prone to shaking in the process of moving in the air chamber 10, and the stability of the air pressure foot pad is improved.

Referring to fig. 1-7, the deviation value between the outer diameter of the pressing block 20 and the inner diameter of the air chamber 10 is α, and the deviation value of α is 0.01 mm-0.05 mm, the α of the present invention is 0.01mm, and the deviation value can prevent the pressing block 20 from shaking while ensuring that the pressing block 20 can move in the air chamber 10.

Referring to fig. 5 to 7, the pressing block 20 is provided with a mounting groove 20a, and the sealing ring 3 is detachably mounted in the mounting groove 20 a; because the sealing ring 3 has a larger function and is an easily-worn part in the utility model, in order to ensure the tightness of the air chamber 10, the sealing ring 3 needs to be replaced after being used for a certain time; the design of the mounting groove 20a enables the sealing ring 3 to be detached from the pressing block 20 at any time, and brings convenience to maintenance work of a user.

specifically, because the stereo set can make a sound and produce the vibration at the during operation, box X can take place the luffing motion because of the vibration, and this in-process produces the noise easily, causes the pollution to tone quality.

Four air pressure foot pads are respectively arranged at four corners of the bottom X of the box body of the sound box to stably support the sound box; each air pressure foot pad makes the gravity center of the box body X always point to the center of the earth by utilizing the principle that gravity vertically faces downwards; so that the vibration force generated by the box body X can directly drive the support 2 to move downwards, thereby activating the buffer effect of the air pressure foot pad, and the generated vibration force can also be changed because the sound wave frequencies of the sound equipment are different, and when the vibration force is changed from big to small, the thrust generated by the air pressure in the air chamber 10 can drive the support 2 to move upwards; therefore, in the working process of the sound equipment, the air pressure foot pad is switched in each state along with the frequency of the sound wave so as to adapt to the sound equipment, and therefore the sound equipment can work stably.

On the other hand, because this inside air chamber 10 that is equipped with of atmospheric pressure callus on the sole possesses certain syllable-dividing effect, cuts off the sound that the stereo set produced, can avoid the sound that the stereo set produced to a certain extent to conduct to ground through the atmospheric pressure callus on the sole and form resonance, lets the more steady transmission sound wave of stereo set, and then improves tone quality.
