The invention discloses a positioning mechanism and a supporting device, and relates to the technical field of jack positioning pins, the positioning mechanism comprises a gear ring arranged on the outer side of a rack pipe in a sleeving mode, and the gear ring is provided with a through hole in the axis direction of the gear ring; the positioning pin is arranged in the through hole in a sliding manner; and the positioning pin adjusting assembly is connected with the gear ring and the other end of the positioning pin, and is used for driving the positioning pin to axially move in the through hole, so that the positioning pin is clamped at the lower part of the supporting cylinder to lock the relative position of the gear ring and the supporting cylinder, or is separated from the lower part of the supporting cylinder to unlock the relative position of the gear ring and the supporting cylinder. The positioning pin is driven by the positioning pin adjusting assembly to axially move in the through hole so as to be clamped to the lower portion of the supporting cylinder, the relative position of the locking gear ring and the supporting cylinder or separated from the lower portion of the supporting cylinder, the relative position of the unlocking gear ring and the supporting cylinder, the locking and unlocking functions are achieved, operation is easy, the adjusting efficiency can be improved, and the adjusting cost is reduced. The problems that in the prior art, the positioning pin inserting and pulling process is troublesome, and the adjusting efficiency is affected can be solved.

    本发明公开了一种定位机构及支撑装置,涉及千斤顶定位销技术领域,包括套设在齿条管外侧的齿环,齿环上设有沿齿环轴线方向的通孔;定位销,其可滑动地设置在通孔内;定位销调整组件,其与齿环连接,并与定位销另一端连接,用于驱动定位销在通孔内轴向移动,以卡接在支撑筒下部,锁定齿环和支撑筒的相对位置,或脱离支撑筒下部,解锁齿环和支撑筒的相对位置。通过定位销调整组件驱动定位销在通孔内轴向移动,以卡接在支撑筒下部,锁定齿环和支撑筒的相对位置,或脱离支撑筒下部,解锁齿环和支撑筒的相对位置,实现锁定和解锁的功能,操作简单,可以提高调节效率,能够解决现有技术中存在定位销插拔过程麻烦,影响调节效率的问题。
