Description

旋转小门
技术领域
本实用新型属于一种工程机械零部件,具体地说,尤其涉及一种旋转小门。 
背景技术
目前工程机械的加油窗口或观察窗口的可打开小门多采用铰链作为旋转轴,结构相对复杂且外观稍差。 
发明内容
本实用新型目的是提供一种旋转小门,以克服现有技术中工程机械的加油窗口或观察窗口结构相对复杂且外观较差的缺陷。 
为解决上述问题,本实用新型采用以下技术方案:旋转小门包括窗口边框、门体和转轴,所述转轴上套有压缩弹簧,所述压缩弹簧上端顶住边框上部,压缩弹簧下端顶住门体,门体通过门锁固定,压缩弹簧有一定的压缩量,从而限制了小门的轴向自由度。 
所述门体下部与边框之间连接处设有垫圈,以保证门体旋转的顺畅。 
与现有技术相比,本实用新型的有益效果是:本实用新型是一种结构简单、外观美观的旋转小门结构。 
附图说明
图1是本实用新型的主视图; 
图2是本实用新型的右视图。 
图中:1、窗口边框;2、门体;3、压缩弹簧;4、转轴;5、垫圈;6、门锁。 
具体实施方式
下面结合附图对本实用新型作进一步描述: 
如图1、图2所示,一种旋转小门,包括窗口边框1、门体2和转轴4,转轴4上套有压缩弹簧3,压缩弹簧3上端顶住窗口边框1上部,压缩弹簧3下端顶住门体2,门体2通过门锁6固定。窗口边框1上设有两个固定转轴的同轴圆孔,门体2上也设有两个同轴圆孔。首先将转轴4和压缩弹簧3安装在门体2上,然后通过压缩弹簧3将转轴4、门体2、垫圈5和压缩弹簧3固定在窗口边框1上,装配好后,压缩弹簧3上端顶住窗口边框1上部,压缩弹簧3下端顶住门体2,压缩弹簧3有一定的压缩量,从而限制了门体2的轴向自由度,门体2 下部与窗口边框1下部之间设有垫圈5以保证旋转顺畅,门体2关闭后使用门锁6固定。
