Automatic air releasing device of vehicle inner tube

Abstract

The invention relates to an automatic air releasing device of a vehicle inner tube, which is characterized in that: the automatic air releasing device of the vehicle inner tube comprises a supporting stand and a transverse tubule which is fixed on the top end of the supporting stand, wherein a plurality of through holes which are arranged along the axial direction of a transverse tubule axis for penetrating the inflating valve of the inner tube are arranged on the tubule wall of the top of the transverse tubule at regular intervals, a plurality of thimbles which can be inserted into the inflating valve of the inner tube are arranged on the bottom of the inner wall of the transverse tubule at regular intervals, the thimbles are arranged along the axial direction of the transverse tubule, each through hole corresponds to one thimble, the center of the through hole is located on the same straight line with the axle center of the thimble, and the height between the top of the thimble and the through hole is 9mm. The invention can carry out the air release for a plurality of inner tubes at once and can ensure that the volume of the air in the inner tubes is 60 percent to 80 percent after releasing, the rejection rate in inner tube installation is greatly reduced, the working efficiency of the inner tube release is increased, and the production cost of the inner tube is simultaneously reduced.

Description

technical field [0001] The invention relates to a gas deflation device for an inner tube of a motor vehicle, in particular to an automatic deflation device for a motor vehicle inner tube with a straight gas nozzle. Background technique [0002] At present, the inner tubes of vehicles such as motorcycles, electric vehicles, and tricycles are assembled by automatic tire loading machines. According to the tire loading requirements of the automatic tire loading machine, before the inner tube is assembled, the inner tube needs to be filled with 60-80% of the gas volume of the inner tube, otherwise it will be difficult to assemble and even the inner tube will be broken. In order to make the gas volume in the inner tube 60-80%, the current method is to first fill the inner tube with gas to 120% to test the air tightness of the inner tube, and then put the gas in the inner tube to 60-80% after checking . Usually, a vacuum pump is used for deflation. But because the vacuum pump ca...

Problems solved by technology

And the cost of each vacuum pump (including pipeline configuration) is more than 15,000 yuan, the service life is 3 years, and the oil needs to be changed once a week, and the cost is 15 yuan

The accumulation of the above items makes the production cost of the inner tube high
