Abstract
A kind of lockout mechanism of go-cart comprises strut bar, the bottom supporting rod that is connected with strut bar, and strut bar is provided with sliding sleeve, and bottom supporting rod can be inserted in the sliding sleeve axially slidably.Sliding sleeve is provided with guiding projection, has the guide groove that extends vertically on the bottom supporting rod, and guiding projection is stuck in the guide groove.Sliding sleeve is provided with lock dog, has at least one locating notch on the bottom supporting rod, and when the lockout mechanism of go-cart was in the lock state, lock dog was stuck in the locating notch.After lock dog withdrawed from from locating notch, bottom supporting rod can be free to slide in sliding sleeve, can carry out the folding of go-cart vehicle frame.
Description
Technical field
The utility model relates to a kind of lockout mechanism that is arranged on the doll carriage.
Background technology
In the prior art, be generally between the front-wheel support of doll carriage and the rear wheel support rotationally and be provided with, so that can be folding relatively between two supports, the locking between these two supports relies on lockout mechanism such as hook grade.For the folding volume go-cart becomes littler, need front-wheel support and rear wheel support slide relative ground be set, but not have lockout mechanism between this slide relative part at present.
Summary of the invention
The utility model purpose provides a kind of lockout mechanism of go-cart, it can be between bottom supporting rod that makes go-cart after the release and sliding sleeve slide relative, make after the locking that the position is relative between bottom supporting rod and the sliding sleeve locks.
For achieving the above object, the technical solution adopted in the utility model is: a kind of lockout mechanism of go-cart, comprise strut bar, the bottom supporting rod that is connected with described strut bar, described strut bar is provided with sliding sleeve, described bottom supporting rod can be inserted in the described sliding sleeve axially slidably, described sliding sleeve is provided with guiding projection, have the guide groove that extends vertically on the described bottom supporting rod, described guiding projection is inserted in the described guide groove, described sliding sleeve is provided with lock dog, have at least one locating notch on the described bottom supporting rod, when the lockout mechanism of described go-cart was in the lock state, described lock dog was stuck in the described locating notch.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
By the setting of guiding projection and guide groove, make and can only slide to axial between sliding sleeve and the end strut bar and can not relatively rotate, help the rigidity of car load.And lock dog can not slide between sliding sleeve and the bottom supporting rod when being inserted in the locating notch to axial, therefore can be so that locked by relative between sliding sleeve and the end strut bar, and then car load can be in stable open mode.
