一种打草机操作手柄拆卸装置,涉及打草机技术领域,其包括上管(1)、与上管(1)滑动连接的下管(2)以及用于锁紧上管(1)与下管(2)的锁紧机构,该拆卸装置还包括与锁紧机构通过转轴(3)转动连接的按钮(4),所述上管(1)上设有上管定位孔(5),下管(2)上设有下管定位孔(6),所述按钮(4)上转轴(3)的一侧设有用于嵌入上管定位孔(5)以及下管定位孔(6)进而防止下管(2)脱离上管(1)的定位块(7),所述按钮(4)上转轴(3)的另一侧设有用于给定位块(7)提供向下嵌入的压力的复位弹簧(8)。这种操作手柄拆卸装置能将下管完全与上管脱离、从而减小包装体积、降低包装和运输成本。
Description
本实用新型涉及打草机技术领域,尤其涉及一种打草机操作手柄拆卸装置。
打草机是用于切割草坪、花园、牧场等地方的杂草的手持式工具。打草机的操作手柄一般包括下管和上管,上管套在下管上,通过上管与下管的相对滑动,从而调节打草机操作手柄的长度。虽然操作手柄能根据需要来调节长度,但是现有技术的打草机操作手柄的上管与下管始终不能完全脱离,这样因为下管并不能完全伸入到上管中,所以两者不能完全脱离会导致包装体积的增加,进而导致包装成本和运输成本的增加。
发明内容:
本实用新型所要解决的技术问题是:提供一种能将下管完全与上管脱离、从而减小包装体积、降低包装和运输成本的打草机操作手柄拆卸装置。
本实用新型所采用的技术方案是:一种打草机操作手柄拆卸装置,包括上管、与上管滑动连接的下管以及用于锁紧上管与下管的锁紧机构,该拆卸装置还包括与锁紧机构通过转轴转动连接的按钮,上管上设有上管定位孔,下管上设有下管定位孔,按钮上转轴的一侧设有用于嵌入上管定位孔以及下管定位孔进而防止下管脱离上管的定位块,按钮上转轴的另一侧设有用于给定位块提供向下嵌入的压力的复位弹簧。
采用以上结构与现有技术相比,本实用新型具有以下优点:设置一个按钮,并且通过按钮上的定位块来限定上管与下管之间是否能够脱离,这样当用户往下按按钮的另一端,此时定位块会随着按钮转动进而脱离下管定位孔,即此时上管与下管之间并没有限定装置,即下管可以从上管中脱离,这样当需要包装运输时可以将下管从上管上脱离,使得包装体积较小,进而使得包装成本和运输成本降低。
作为优选,锁紧机构包括套设在上管外且与上管固定连接的上管固定套以及套设在上管固定套外且与上管固定套螺纹连接用于挤压上管固定套进而调节上下管之间松紧度的锁紧套,上管固定套上设有安装孔,按钮设置在安装孔内且通过转轴与上管固定套转动连接。采用上管固定套与锁紧套之间的配合来调节上管与下管的松紧度,调节起来比较方便,并且将按钮设置在上管固定套上,这样就安装比较方便,且结构简单。
作为优选,按钮上转轴另一侧设有定位凸起,上管固定套上设有定位槽,复位弹簧套设
在定位凸起上且伸入定位槽内。将复位弹簧设置在定位凸起与定位槽之间,这样复位弹簧不会脱落,使得整个按钮可靠性较高。
作为优选,定位块用于嵌入上管定位孔以及下管定位孔的一端为圆弧形。这样定位块嵌入上管定位孔以及下管定位孔时不容易磨损,使得整个拆卸装置使用寿命较高。
作为优选,上管固定套内壁设有导向凸筋,下管上设有与导向凸筋配合的导向凹槽。这样设置将下管安装到上管上时不会错位,进而使得安装孔、上管定位孔以及下管定位孔的位置能相匹配,进而使得上管与下管在适当的位置时定位块能嵌入到这三者内。
作为优选,该拆卸装置还设有用于防止上下管脱开后割破电线的护线套管,护线套管与下管紧配合,护线套管为塑料材料制成,且护线套管上设有与下管导向凹槽相匹配的导向槽,并且护线套管上还设有与下管定位孔位置相配且供定位块嵌入的开口槽。当上管与下管完全脱离后,上管与下管内的电线还在,并且上管与下管通常是采用金属材料制成的,而上管上设有塑料的上管固定套,所以在下管上也设置一个塑料的护线管套,能有效的保护好下管内的电线,并且还设有了导向槽以及开口槽,这样就不会影响拆卸装置的正常使用。

以下结合附图与具体实施方式对本实用新型做进一步描述,但是本实用新型不仅限于以下具体实施方式。
如图1以及图2所示:一种打草机操作手柄拆卸装置,包括上管1、与上管1滑动连接的
下管2以及用于锁紧上管1与下管2的锁紧机构,其特征在于:该拆卸装置还包括与锁紧机构通过转轴3转动连接的按钮4,上管1上设有上管定位孔5,下管2上设有下管定位孔6,按钮4上转轴3的一侧设有用于嵌入上管定位孔5以及下管定位孔6进而防止下管2脱离上管1的定位块7,按钮4上转轴3的另一侧设有用于给定位块7提供向下嵌入的压力的复位弹簧8。
锁紧机构包括套设在上管1外且与上管1固定连接的上管固定套9以及套设在上管固定套9外且与上管固定套9螺纹连接用于挤压上管固定套9进而调节上下管之间松紧度的锁紧套10,上管固定套9上设有安装孔11,按钮4设置在安装孔11内且通过转轴3与上管固定套9转动连接。上管固定套9一部分是套设在上管1外,还有一部分是具有弹性且与下管2接触,这样当锁紧套10旋转锁紧时,上管固定套9具有弹性那一部分会压紧下管2,使得上管1与下管2之间不能任意滑动,而当锁紧套10旋转松开时,上管固定套9具有弹性那一部分会与下管2松开,此时上管1与下管2之间可以任意滑动。
如图2以及图3所示:按钮4上转轴3另一侧设有定位凸起12,上管固定套9上设有定位槽13,复位弹簧8套设在定位凸起12上且伸入定位槽13内。
如图3所示:定位块7用于嵌入上管定位孔5以及下管定位孔6的一端为圆弧形。
如图4与图5所示:上管固定套9内壁设有导向凸筋14,下管2上设有与导向凸筋14配合的导向凹槽15。
如图6所示:该拆卸装置还设有用于防止上下管脱开后割破电线的护线套管16,护线套管16与下管2紧配合,护线套管16为塑料材料制成,且护线套管16上设有与下管2导向凹槽15相匹配的导向槽17,并且护线套管16上还设有与下管定位孔6位置相配且供定位块7嵌入的开口槽18。
本申请的工作原理是:当按钮4处于正常状态时,如图7所示:下管2往左拉到极限时,按钮4上的定位块7会依次嵌入到上管定位孔5、下管定位孔6以及开口槽18内,使得下管2不能再继续被往左拉动,此时相当于下管2是不能从上管1上脱离的;当按钮4处于被压下状态时:如图8所示:此时按钮4右端有压力,使得定位块7从开口槽18以及下管定位孔中6脱离,此时下管2可以继续往左移动,进而脱离上管1。
