Description

一种带锁定装置的气弹簧
技术领域
本发明涉及一种带锁定装置的气弹簧,可以使气弹簧力不变而气弹簧长度伸长。
背景技术
现有气弹簧只有一个气腔,随着活塞杆伸出或缩回,气弹簧的力也会相应地减小或增大;当面临一种使用工况,例如某雷达罩在举升过程中需要气弹簧长度伸长而力不变时,则现有气弹簧不能满足要求。
发明内容
提供了一种带锁定装置的气弹簧,该型气弹簧包括弹簧1、锁定外壳2、转动销轴3、活塞杆I4、活塞杆II5、气腔间隔8、轴承端9以及缸筒10;
气腔间隔8将缸筒10分为气腔A6和气腔B7,所述的活塞杆I4设置在气腔A中,所述的活塞杆II5设置在气腔B中,所述的活塞杆I4与轴承端9连接,轴承端9和锁定外壳2通过转动销轴3可相对转动地连接为一体,转动销轴3、锁定外壳2、轴承端形成一个杠杆结构,弹簧1的一端固定连接在轴承端9上,锁定外壳的一端压在弹簧1的另一端上,锁定外壳的另一端设有卡止部,能够卡止在缸筒10的端部;
当气弹簧完全压缩时,由于弹簧1的弹力作用,锁定外壳的另一端向下压卡住缸筒端部,由此处于锁定状态,如图4中的压缩位置,且不能伸出;在锁定状态下拉动气弹簧,则只有活塞杆II5向外伸出;
当向下压锁定外壳的一端时,在杠杆作用下卡止部会向上扬起,由此气弹簧实现解锁,此时活塞杆I4能够伸出。
有益效果
改进现有气弹簧,将一个气腔分为两个气腔,变一个活塞杆为两个活塞杆,两端皆可伸展与压缩;结构简单可靠,制造工艺性较好。
附图说明
图1为本发明的结构示意图;
图2为本发明解锁后一端伸出的示意图;
图3为锁止后一端伸出的示意图;
图4为本发明两端完全伸出的示意图;
其中:1-弹簧、2-锁定外壳、3-转动销轴、4-活塞杆I、5-活塞杆II、6-气腔A、7-气腔B、8-气腔间隔、9-轴承端、10-缸筒。
具体实施方式
提供了一种带锁定装置的气弹簧,该型气弹簧包括弹簧1、锁定外壳2、转动销轴3、活塞杆I4、活塞杆II5、气腔间隔8、轴承端9以及缸筒10;
气腔间隔8将缸筒10分为气腔A6和气腔B7,所述的活塞杆I4设置在气腔A中,所述的活塞杆II5设置在气腔B中,所述的活塞杆I4与轴承端9连接,轴承端9和锁定外壳2通过转动销轴3可相对转动地连接为一体,转动销轴3、锁定外壳2、轴承端形成一个杠杆结构,弹簧1的一端固定连接在轴承端9上,锁定外壳的一端压在弹簧1的另一端上,锁定外壳的另一端设有卡止部,能够卡止在缸筒10的端部;
当气弹簧完全压缩时,由于弹簧1的弹力作用,锁定外壳的另一端向下压卡住缸筒端部,由此处于锁定状态,如图4中的压缩位置,且不能伸出;在锁定状态下拉动气弹簧,则只有活塞杆II5向外伸出;
当向下压锁定外壳的一端时,在杠杆作用下卡止部会向上扬起,由此气弹簧实现解锁,此时活塞杆I4能够伸出。
