Description

The automatic takeup of go-cart ceiling

The utility model relates to a kind of ceiling of doll carriage.

In the prior art, generally be provided with ceiling on the vehicle frame of doll carriage, the bottom of this ceiling bar and vehicle frame pivotal joint, ceiling can rotate with respect to the vehicle frame fore-and-aft direction, and ceiling also can folding or opened, and is provided with positioning teeth between ceiling bar and the vehicle frame, make ceiling be located in a certain position, but in the rotation process of ceiling bar, positioning teeth can send the sound of " clatter, clatter ", agitation child's sleep.

The purpose of this utility model is to provide a kind of automatic takeup that makes ceiling bar go-cart ceiling of auto-tensioning ceiling in certain zone.

The technical solution of the utility model is: a kind of automatic takeup of go-cart ceiling, comprise vehicle frame, be arranged at the fluffy inserted link on the described vehicle frame, at least the fluffy bar of fluffy bar and back before being provided with on the described fluffy inserted link, fluffy bar or back fluffy bar and described fluffy inserted link pivotal joint before described, described preceding fluffy bar afterwards is connected with ceiling cloth between the fluffy bar with described; The top of described fluffy inserted link is provided with outside race, the preceding fluffy bar turning block of captiveing joint with preceding fluffy bar is inserted in the described outside race and pivotal joint between the two, have the tensioning guiding breach of radial depressions before described on the fluffy bar turning block, being provided with in the described fluffy inserted link inner chamber to be pressed with on sliding shoe and the sliding shoe makes sliding shoe have spring towards preceding fluffy bar turning block mobile trend, the top of this sliding shoe has the guiding surface of sliding shoe, and the guiding surface of described sliding shoe inserts in the described tensioning guiding breach and with one of them breach inwall and contacts.

The utility model compared with prior art has following advantage:

Because the guiding surface of sliding shoe contacts with a inwall in the tensioning guiding breach, so sliding shoe gives anti-clockwise power of preceding fluffy bar turning block, the trend that this power makes preceding fluffy bar have to rotate counterclockwise and tensioning ceiling always.When breaking away from tensioning guiding breach at the top of sliding shoe, preceding fluffy bar can stop in arbitrary position, can stably fold and steadily noiseless.Because ceiling can always be in tensioned state when opening, thereby the outward appearance of having beautified car load.

The utility model will be further described below in conjunction with drawings and Examples:

Working state figure when accompanying drawing 1 is not tensioned for fluffy bar before of the present utility model;

Accompanying drawing 2 is the preceding working state figure of fluffy bar in the tensioning process of the present utility model;

Accompanying drawing 3 is the working state figure after the last tensioning of preceding fluffy bar quilt of the present utility model;

Working state figure when accompanying drawing 4 is positioned under folding state for fluffy bar before of the present utility model;

Accompanying drawing 5 is the scheme drawing of ceiling of the present utility model under various states; Wherein:
