【技术实现步骤摘要】
具有锁位和卸压结构的膨胀箱盖
本技术属于汽车配件
,具体涉及一种具有锁位和卸压结构的膨胀箱盖。
技术介绍
汽车中的冷却系统压力需要膨胀箱,当循环冷却系统中的冷却液减少时,膨胀箱里的冷却液流向循环冷却系统,使循环冷却系统中的冷却液得于补充,为了保证膨胀箱的使用稳定性,在膨胀箱上需要使用膨胀箱盖,传统技术的膨胀箱盖是螺纹连接在所述膨胀箱上,其虽然可以实现盖合,但是在实际使用过程中,膨胀箱内会存在一定的压力,从而容易造成膨胀箱盖从膨胀箱上脱离,同时由于膨胀箱盖为密封式结构,故而在打开时由于膨胀内压力较高,也容易产生危险,故而适用性和实用性受到限制。
技术实现思路
本技术的目的是提供一种结构设置合理且适用性强的具有锁位和卸压结构的膨胀箱盖。实现本技术目的的技术方案是一种具有锁位和卸压结构的膨胀箱盖,包括盖体,在所述盖体的内壁上固定有内螺纹,在所述盖体的外侧设置有外盖,所述外盖与所述盖体的顶面之间设置有间隙,所述外盖的底端与所述盖体的外壁之间固定有横向连接圆环,在所述盖体的侧壁下部设置有锁位插槽,所述内螺纹处于所述锁位插槽的上方,在所述外盖的底部设置有抵压翘杆,所述抵压翘杆的中部通过旋转轴连接在所述外盖上,在所述抵压翘杆的底端固定有锁位卡块,在所述抵压翘杆与所述横向连接圆环之间固定有受力拉簧,所述抵压翘杆在所述受力拉簧的作用下使锁位卡块卡入锁位插槽内并抵压在膨胀箱的外壁上,在所述横向连接圆环上固定的卸压通孔,所述卸压通孔与抵压翘杆位置错开设置。在所述盖体的顶面均匀固定有W形凹槽,在所述盖体的顶壁中心固定有通孔,在所述外盖的顶壁底面固定有向外侧倾斜的阻滞板。在所述盖 ...
