Description

一种扩张通道管的管架
技术领域
本发明涉及的是一种医疗手术用器械,尤其是一种扩张通道管的管架。
背景技术
在现有技术中,公知的技术是在用的通道管管架,目前使用的管架也可以用移动支腿移动来实现移动扩张,用转动支腿的转动来实现转动扩张,但其转动支腿的转动结构存在结构比较复杂和使用不便的缺陷,这是现有技术所存在的不足之处。
发明内容
本发明的目的,就是针对现有技术所存在的不足,而提供一种扩张通道管的管架技术方案,该方案采用螺栓推顶的方式来转动转动支腿,故其结构简单也易于操作。
本方案是通过如下技术措施来实现的:包括有带齿条的固定梁,在固定梁上装有可沿固定梁移动的移动支腿,在该移动支腿上有带棘轮的移动转柄,在固定梁的一端则固定有固定支腿,在所述的移动支腿和固定支腿的顶端各装有带通道管固定螺栓并可单向转动的转动支腿,本方案的特点是在所述的移动支腿和固定支腿上各有一个固定凸台,在所述的两转动支腿上对应固定凸台有转动凸台,在两转动凸台上有螺孔,螺孔上则装有转动螺栓。本方案具体的特点还有,所述的移动支腿上的固定凸台与移动支腿是一体结构。所述的固定支腿上的固定凸台与固定支腿是一体结构。所述的两转动支腿上的转动凸台与转动支腿是一体结构。
本方案的有益效果可根据对上述方案的叙述得知,由于该方案中在移动支腿和固定支腿上各有一个固定凸台,在两在支腿上对应固定凸台有转动凸台,在两转动凸台上有螺孔,螺孔上则装有转动螺栓。这一结构,转动转动凸台上的转动螺栓可控制转动凸台与固定凸台的张合,从而控制转动支腿与对应的移动支腿或固定支腿之间的转角,实现了通道管的转动扩张。由此可见,本发明与现有技术相比结构简单也易于操作,故具有实质性特点和进步,其实施的有益效果也是显而易见的。
附图说明
图1为本发明具体实施方式的部分剖视结构示意图。
图2为图1的A-A剖视结构示意图。
图中,1为通道管固定螺栓,2为转动凸台,3为转动螺栓,4为固定凸台,5为移动转柄,6为固定架,7为移动支腿,8为转动支腿,9为固定支腿。
具体实施方式
为能清楚说明本方案的技术特点,下面通过一个具体实施方式,并结合其附图,对本方案进行阐述。
通过附图可以看出,本方案的扩张通道管的管架有带齿条的固定梁,在固定梁上装有可沿固定梁移动的移动支腿,在该移动支腿上有带棘轮的移动转柄,在固定梁的一端则固定有固定支腿,在所述的移动支腿和固定支腿的顶端各装有带通道管固定螺栓并可单向转动的转动支腿,本方案所述的转动支腿的单向转动结构,是在所述的移动支腿和固定支腿上各有一个固定凸台,在所述的两转动支腿上对应固定凸台有转动凸台,在两转动凸台上有螺孔,螺孔上则装有转动螺栓,这样在转动转动凸台上的转动螺栓时,可控制转动凸台与固定凸台的张合,从而控制转动支腿与对应的移动支腿或固定支腿之间的转角,实现了通道管的转动扩张。为了保证强度,所述的移动支腿上的固定凸台与移动支腿是一体结构;所述的固定支腿上的固定凸台与固定支腿是一体结构;所述的两转动支腿上的转动凸台与转动支腿是一体结构。
