Structure on end part of linkage curved bar

Abstract

The invention discloses a structure on the end part of a linkage curved bar. The structure is characterized in that: an upper edge of an upper linkage sheet is parallel to and higher than an upper edge of a lower linkage sheet; a lower edge of the upper linkage sheet is parallel to and higher than a lower edge of the lower linkage sheet; an upper arc surface is formed at the connection position of the upper edges of the upper linkage sheet and the lower linkage sheet; a lower arc surface is formed at the connection position of the lower edges of the upper linkage sheet and the lower linkage sheet; both sides of the end part of the upper linkage sheet are provided with an assembly platform; and linkage posts are arranged on the surfaces of the assembly platforms. The integral structure of a product is simple; and the structure can be subjected to rear deflection linkage control only by matching a curved linkage bar, is connected with the linkage curved bar by a sleeve and difficultly separated from the linkage curved bar, has a stable working condition, is convenient to operate smoothly, requires low torsion force during deflection, can be operated by a single hand, has extremely high practicability, and has outstanding substantial characteristics and remarkable progress compared with the prior art.

Description

technical field [0001] The invention relates to the technical field of baby carriage accessories, in particular to an end structure of a linkage curved rod, and in particular to its mechanical connection structure. Background technique [0002] Reference document, patent number: ZL200720059625.0, application date: 2007.11.16, publication (announcement) number: CN201169347, this case discloses a "positioning and steering device for baby carriages", including the body, steering wheel, wheels, guide columns, and the bottom of the steering wheel There is a bar-shaped block, and the upper end of the guide column is provided with a card slot that matches the block. There are fixed shafts formed on both sides near the lower end. The shaft is rotationally connected to the wheel. [0003] It is not difficult to see from the above comparative documents that the structure of the existing child carriage rear control steering device is relatively complicated, and there are many accessor...
