Expansion pulling handle rod of baby carriage

Abstract

The invention relates to a stretching push rod of a baby stroller, which comprises a lower push rod provided with a lower pipe cavity, and an upper push rod; the upper push rod is provided with a locking pin in a slidable mode; the lower pipe body is fixedly provided with a plastic lining piece with a cavity; the upper push rod is inserted in the cavity in a slidable mode; the plastic lining piece is provided with at least two locking holes; the locking pin is provided with a locking operating position and a unlocking operating position, when the locking pin is atthe locking operating position, the locking pin is inserted in a locking hole, when the locking pin is at the unlocking operating position, the locking pin separates from all the locking holes. When the position of the upper push rod is regulated relative to the lower push rod, the upper push rod slides in the cavity of the plastic lining piece, the friction coefficient between the upper push rod and the plastic lining piece is rather small; therefore, the users saves labor in regulation.

Description

technical field [0001] The invention relates to a child's stroller, in particular to a telescopic push handle rod of the child's stroller. Background technique [0002] The telescopic push handle rod of the children's stroller in the prior art includes a lower push rod and an upper push rod with a lower lumen, the upper push rod is slidably provided with a locking pin, and the upper push rod directly slides Inserted into the lower lumen, the lower push rod has a plurality of locking holes, when locked, the locking pin on the upper push rod is directly inserted into a locking hole on the lower push rod, when When it is necessary to adjust the position of the upper push rod relative to the lower push rod, the upper push rod slides in the lower lumen of the lower push rod. The lower push rod is usually made of metal material, and the coefficient of friction between the two is relatively large during the sliding process, and the user is laborious to adjust it.
