Description

Technical Field

[0001] The utility model belongs to the technical field of basketball quantitative inflation, and particularly relates to a quantitative inflation device for basketball production. Background Technique

[0002] In the prior art, through retrieval, it is found that the Chinese patent discloses a "quantitative inflation device for basketball production", and its application number is "CN202222320915.3". The main body of this patent is the main body and the box body. The beneficial effects of the utility model are as follows: By arranging an air extraction channel inside the upper module, the expansion of the basketball inner bladder applies pressure to the moving plate, causing the moving plate to drive the blocking shaft to slide in the air delivery channel. The air extraction channel is blocked by the blocking block, so that the air extraction pipe cannot deliver gas to the air column, resulting in the air delivery pipe being unable to deliver gas to the inflation pipe, thereby stopping the inflation of the inner bladder, making the air volume in the inner bladder uniform, and the elasticity of the inner bladder after inflation is basically the same, greatly reducing the rejection rate of subsequent production; By arranging a fixed shaft inside the first and second air valves, and using the movement of the baffle on the fixed shaft, the gas in the inner bladder cannot flow into the air delivery pipe through the inflation pipe. When the air extraction channel is blocked by the blocking shaft, the external gas cannot flow into the air column through the air delivery channel, thereby inflating the inner bladder quantitatively.

[0003] However, after the inflation process is completed, there is a significant design defect in the above device. The basketball cannot be automatically disconnected from the inflation pipe. The operator must manually intervene to disconnect the connection of the inflation pipe by opening the upper module and take out the fully inflated basketball. This additional step not only consumes more time but also greatly reduces the overall working efficiency. Summary of the Utility Model
