Abstract

本实用新型涉及一种打气筒,特别是一种结构简 单,漏气少的手动微型打气筒。它包括有套筒6、端 盖1、尾盖3以及活塞10、手柄4。其主要特征是:在 端盖上接有气嘴2,在活塞上有一气体单向阀。由于 设计了气嘴和单向阀,减少了在打气过程中的漏气现 象,因而具有结构简单、使用方便、效率高、寿命长等 优点,尤其适合自行车外出时随车携带使用。

Description

本实用新型涉及打气筒,特别是携带方便,能对自行车轮胎打气的手动微型打气筒。
长期以来,自行车轮胎充气均需在修理部找打气筒打气,使用不方便,特别是自行车行至路途中需加气时更感打气不方便,传统打气筒及近几年市场上有的手动微型打气筒,因其顶部钢焊易损,不便修复,且其气嘴压气垫容易脱落不易修复,再则还存在皮碗活塞容易漏气,容易损坏、效率低。
本实用新型的目的就是设计一种结构简单、易制造、使用方便寿命长的手动微型打气筒。
本实用新型的目的是通过以下结构实现的:手动微型打气筒包括有套筒、端盖、尾盖以及活塞、手柄等,其主要特征是:在端盖上接有一气嘴,在活塞上设有一气体单向阀;使用时通过活塞上的单向阀对气筒充气压缩,并经气嘴将筒体内的气体压入轮胎内。
本实用新型与现有技术相比具有结构简单,体积小,使用方便,寿命较长,易制造等优点;尤其适合自行车外出时随车携带使用。
本实用新型的附图说明如下:
图1为本实用新型的结构示意图;
图2为气嘴结构示意图;
图3为活塞结构示意图。
图中:1端盖,2气嘴,3尾盖,4手柄,5手柄连接件,6套筒,7气嘴筒体,8密封垫,9气嘴进气管,10活塞,11气道,12密封圈凹槽,13密封圈。
下面结合附图和实施例对本实用新型作进一步描述:
如图1所示,本实用新型包括有套筒6、端盖1,尾盖3以及活塞10,手柄4,在端盖上接有气嘴2,在活塞上有一气体单向阀,气嘴是由气嘴进气管9和气嘴筒体7构成,在气嘴筒体内壁卡有一有气孔的密封垫,以适应微型打气筒不能漏气的要求,如图2所示;气体单向阀是由活塞体上的密封圈凹槽12和通在凹槽后壁的气道11,以及密封圈13构成,当活塞在手柄作用下推进时,密封圈在凹槽内后移封住气道,筒体内气体受压入气嘴,反之当活塞在手柄作用下拉退时,密封圈在凹槽内前移,打开气道,气体进入筒体内,如此反复实现打气的目的,如图3所示。由于采用单向阀的活塞使用更方便,漏气少,打气效率高,尤其是微型打气筒使用效果更好。
