Abstract

一种应用于自行车、摩托车、拖拉机,微型汽车轮胎充气用的脚踏式双缸打气筒,其特征在于在初压筒上设置一增压筒,增压筒上端接压力杆,下端接有气垫、胶板,气垫上设有通气孔,增压筒沿初压筒内壁可上下工作,随着增压筒上下移动,即完成增压给轮胎充气。本实用新型运用了杠杆及增压筒设置原理,增压筒同时也是气垫推杆,充分利用了空间,其具有结构简单,便于携带,打气时省力等优点。

Description

脚踏式双缸打气筒
本实用新型涉及一种自行车、摩托车、拖拉机,微型汽车轮胎充气用的脚踏式双缸打气筒。
现有脚踏式充气筒都是单缸的,未设增压筒。市场上销售的带增压筒打气筒、体积长,不便于携带,其使用时是利用手和身体所产生重力进行工作,故打气时存在着费力,打气筒不稳等缺点。
本发明目的是提供一种脚踏式双缸打气筒,利用杠杆和增压筒设置原理,解决利用手和身体作为重力以及打气时费力等问题,其在使用时省力,稳定性强。
本发明是通过如下方式完成的,即其包括压力杆(1)、增压筒(2)、胶板(3)、气垫(4)、初压筒(5)、支架(6)、弹簧(7)、气绳(8),支架(6)与初压筒(5)底端套接,压力杆(1)与增压筒(2)上端套接,压力杆(1)与支架(6)为活销接,在接端处设有弹簧(7),其特征在于增压筒(2)上端设有气绳(8),增压筒(2)下端设有一孔,上覆盖胶板(3),胶板(3)一端固定在增压筒(2)下端孔上,另一端可上下运动,增压筒(2)底端固定有一气垫(4),气垫(4)上设有通气孔,增压筒(2)可沿初压筒(5)内壁带动气垫(4)上下运动。
附图及实施例:
附图为脚踏式双缸打气筒结构示意图
1是压力杆,2是增压筒,3是胶板,4是气垫,5是初压筒,6是支架,7是弹簧,8是气绳。
下面结合附图进一步说明:
在使用时,将气筒向上置于地面,用脚踏压力杆(1)向下推动增压筒(2),胶板(4)由于压力张开,气体通过气垫(4)通气孔、胶板(4)、增压筒(2)下端孔进入增压筒增压,胶板(4)阻挡增压后的气体跑出,当脚抬起时,在弹簧(7)的作用下,压力杆(1)返回原位,将增压筒(2)和气垫(4)拉回原位,连续踏动压力杆(1),即可将增压后气体通过气绳(8)向轮胎充气。
本发明具有结构简单,便于携带,使用时省力,稳定性强等优点。
