[0001] The utility model mainly relates to the technical field of air pipes of air pumps, in particular to an air pipe pressure valve of an air pump which can rotate arbitrarily. Background Art

[0002] The air pump, also known as an air pump, works by running the motor. When the motor is running, the valve of the connecting vessel is opened by the atmospheric pressure, and the gas enters the air cylinder. When air is inflated into the tire, the valve is closed by the air pressure in the air cylinder, and the gas enters the tire.

[0003] At present, small air pumps are widely used because they are easy to carry and have a wide range of applications, such as inflating automobile tires, non-motor vehicle tires, balls, inflatable toys and other products.

The joint assembly currently used at one end of the flexible connecting tube includes a valve core, a valve nut connected to the inflated item, one end of the valve core is inserted into the end of the connecting tube, and the valve nut is sleeved on the outside of the part of the valve core that is located outside the connecting tube. However, during the use of the air pump, since the air nozzle on the tire is in a random direction, the air nozzle on the air pump is fixedly connected to the air pipe of the air pump. After the air nozzle of the air pump matches the air nozzle on the tire, the air pump needs to be twisted according to the direction of the tire air nozzle for use, and the actual use experience is poor.
