(54) Sealing structure for inflation nozzle for inflation pump


(57) An inflation nozzle (20) for an inflation pump includes a housing (21), a plug seat (10), a plug (31; 32; 33), and a cap (22). The inflation nozzle (20) can be engaged with a valve (A; A'; B; C) of a tire to be inflated. The plug seat (10) includes a head (13) and a gas tube (12). A groove (101) is formed on an outer periphery of the gas tube (12). A seal ring (30) is received in the groove (101) and slightly protrudes out of the groove (101). The plug (31; 32; 33) is mounted in the head (13) and is in scaling contact with the valve (A; A'; B; C) during inflation. The inner periphery (214) of the housing (21) abuts against the seal ring (30) received in the groove (101) to provide sealing therebetween.
