The invention discloses a quick release type locking structure which comprises a hoop, and the hoop is provided with a locking seam I, a spring positioning pin used for limiting a telescopic pipe arranged in the hoop in a penetrating mode and a locking piece used for being matched with the locking seam I to lock the telescopic pipe arranged in the hoop in a penetrating mode. The second spring positioning pin is arranged on the inner wall of the main pipe in a protruding mode, the anti-disengagement groove is formed in the end of the telescopic pipe, and after the telescopic pipe and the main pipe are installed in the hoop in the two opposite directions respectively, the second spring positioning pin is clamped into the anti-disengagement groove. According to the electric drive cart adopting the quick-release locking structure, the locking piece is matched with the locking seam I, so that the inner wall face of the hoop is tightly attached to the outer wall face of the telescopic pipe, the stress contact area of the hoop and the outer wall face of the telescopic pipe is increased, the phenomenon that the telescopic pipe shakes is avoided, when the electric drive cart is used, the stress borne by the telescopic pipe is not concentrated on a certain point any more, and the service life of the telescopic pipe is prolonged. The phenomenon that the telescopic pipe is easy to wear is avoided; the spring positioning pin abuts against the outer wall of the telescopic pipe, and the telescopic rod reaching the needed position is rapidly and accurately limited.

    本发明公开一种快拆式锁紧结构,包括抱箍,抱箍上设有锁紧缝Ⅰ、用于对抱箍内穿设的伸缩管进行限位的弹簧定位销、用于和锁紧缝Ⅰ配合以对抱箍内穿设的伸缩管进行锁死的锁紧件;还包括凸设于主管内壁上的第二弹簧定位销、设置于伸缩管端部的防脱槽,当伸缩管、主管从相对的两个方向分别装入抱箍内后,第二弹簧定位销卡入防脱槽内。采用前述快拆式锁紧结构的电驱推车通过锁紧件和锁紧缝Ⅰ的配合,使抱箍的内壁面紧贴伸缩管的外壁面,增大二者的受力接触面积,避免了伸缩管晃动的现象,而且在使用电驱推车时,伸缩管所受的力不再集中于某个点上,避免伸缩管易磨损的现象;通过弹簧定位销抵接伸缩管的外壁,对到达所需位置的伸缩杆快速进行准确限位。
