Air cushion adjusting device

Abstract

An air cushion adjusting device comprises a valve body which can be mounted at a sole, a pushing member and an adjusting member, wherein one end of the valve body is provided with an air delivery part; one side of the valve body is provided with an air input part and an air output part; the air input part is connected with an air inflation device, and the air output part is connected with a one-way valve communicated with the external; the pushing member is mounted in the valve body, and two ends of an elastic member are elastically butted with the pushing member and the adjusting member respectively; when the air pressure in an air cushion is higher, the air pressure pushes against the pushing member to resist the elastic member to make the air current flow out from the air output part to the external; when the air pressure of the air cushion is normal, the elastic member pushes the pushing member to isolate the air delivery part relative to the air output part to make the air input part only deliver the air to the air cushion from the air delivery part.

Description

technical field [0001] The invention relates to an air cushion regulating device, in particular to an air cushion regulating device capable of fine-tuning the air transmission state between the air cushion and the inflatable device. Background technique [0002] Generally, air cushions are installed in modern running shoes or sports shoes. Using the elastic force provided by the air cushions, the human feet can feel comfortable when stepping on the insoles, and will not feel pain due to impact with the hard ground. It has the functions of protecting the muscles of the feet and relieving fatigue, so many related companies have developed and improved insole technology. [0003] Moreover, the existing air cushions are often too hard due to high inflation saturation, which is not conducive to comfortable stepping, or the air cushions are designed with air holes to cooperate with the inflator to discharge excess gas, but it is prone to air holes due to long-term use. The shortco...

Problems solved by technology

[0005] However, although this kind of existing inflation adjustment structure can provide the effect of adjusting the gas flow, it does not have the function of fine adjustment, especially there is no mutual basis between the inflation device and the air cushion, when the adjustment device is set at When the air volume is fixed, even if the air cushion is full, the inflator can continue to deliver air to the air cushion, which will cause the air cushion to be too full, or cause the air holes to expand due to the continuous outflow of gas, which will affect the pedaling comfort And the normal size of the air hole, so its practicability is quite limited, it is necessary to develop an air cushion adjustment device that can fine-tune the air transmission state between the air cushion and the inflatable device
