Foldable stroller with cooperating joint locking structure

[technical field]

The utility model belongs to perambulator technical field, more particularly to the foldable stroller with cooperating joint locking structure.

[background technique]

Stroller is baby's " vehicles ", and someone is needed to assist to push or haul the car that can just walk.It is auxiliary Parent is helped to carry the necessary vehicles that baby goes into the street, takes a walk.

As perambulator is widely used, perambulator is designed as the mode folded due to needing convenient transportation and use mostly, But volume is still very big after existing Pram folding, and structure is complicated for folding, and folding process is cumbersome, is not easy to quickly receive It closes.

[summary of the invention]

To solve the problems, such as that structure is complicated, folding process is cumbersome and inconvenient in use, this reality for Pram folding in the prior art The foldable stroller with cooperating joint locking structure is provided with novel.

The utility model is achieved through the following technical solutions:

Foldable stroller with cooperating joint locking structure, including front frame, be connected on rear side of the front frame after Vehicle frame, the front frame include that upper front frame and the lower front frame hinged with the upper front frame, the Rear frame are connected to The hinged place of the upper front frame and lower front frame, and hinged place is additionally provided with the upper front frame and lower front frame can be made along hinged The rotation retracting structure and limit the upper front frame and lower front frame along hinged place turn that place is rotated to the Rear frame direction Dynamic cooperating joint locking structure.

As above have a foldable stroller of cooperating joint locking structure, the rotation retracting structure including can relatively rotate and Sequentially connected first link block, the second link block and third link block, first link block and the upper fore-stock connect It connects, second link block is connect with the lower fore-stock, and the third link block is connect with the Rear frame, and the linkage Joint locking structure is set between first link block and the second link block.

As above the foldable stroller of cooperating joint locking structure is had, the cooperating joint locking structure includes；Unlock is pressed Button；Set on the third link block outside and stretch in third cavity, and be additionally provided with Flexible Reset in the unblock button Part；First locating part is located in third cavity and connect with the unblock button；Second locating part is located in third cavity；Linkage Unlock piece is set in the second cavity and between first locating part and the second locating part；

Mouth is led equipped with the first arc in second cavity and the second arc leads mouth, is equipped with third in first cavity Arc leads mouth and the 4th arc leads mouth, and first arc leads mouth, the second arc leads mouth, third arc leads mouth, the 4th arc It leads and is all provided with the limit indexing that oriented radial direction extends on the both ends of mouth, the limit indexing includes the indexing of unfolded state limit and folds shape State limit indexing, the unfolded state limit indexing that first arc leads the unfolded state limit indexing of mouth and third arc leads mouth is opposite, The unfolded state limit indexing that second arc leads the unfolded state limit indexing of mouth and the 4th arc leads mouth is opposite；First limit Position part, which from first arc leads mouth and stretches to third arc, leads in mouth, and second locating part is equipped with from the second arc and leads mouth It stretches to the 4th arc and leads the second limiting section in mouth；

When first locating part is located at the indexing of unfolded state limit or collapse state limit indexing, first connection can be limited Block and the second link block are rotated relative to the third link block, and pressing the unblock button makes it drive first locating part to moving up It is dynamic to be detached from the unfolded state limit indexing that the first arc leads mouth and third arc leads mouth, and the second limiting section is acted in linkage of unlocking part Under move down and be detached from that the second arc leads mouth and the 4th arc leads the unfolded state limit indexing of mouth, first link block and second Link block can be rotated relative to the third link block.

As above have cooperating joint locking structure foldable stroller, the linkage of unlocking part include be stacked with setting and Middle part is hinged on the first STATEMENT OF FEDERALLY SPONSORED and the second STATEMENT OF FEDERALLY SPONSORED in the second cavity, and first STATEMENT OF FEDERALLY SPONSORED is equipped with for described the One locating part protrudes into and leads mouth to the first of the extension of upper left side arc, and second STATEMENT OF FEDERALLY SPONSORED, which is equipped with, supplies first locating part It protrudes into and second to the extension of upper right side arc leads mouth, the lower end of first STATEMENT OF FEDERALLY SPONSORED is additionally provided with the first guiding notch, described The lower end of second STATEMENT OF FEDERALLY SPONSORED is equipped with the second guiding notch；Pressing the unblock button makes it that the first locating part be driven to move up, First STATEMENT OF FEDERALLY SPONSORED and the second STATEMENT OF FEDERALLY SPONSORED rotate under the action of first leads mouth and second leads mouth along middle part hinged place, and the second limit Position part moves down under the action of the first guiding notch and the second guiding notch.

As above have cooperating joint locking structure foldable stroller, it is described first guiding notch include the first bayonet position, Guiding positioned at the second bayonet position of first bayonet position lower right and between the first bayonet position and the second bayonet position Segmental arc, second locating part further include stretch to it is described first guiding notch and second guiding notch in guiding it is convex It rises；

When first locating part moves up, the first STATEMENT OF FEDERALLY SPONSORED first lead mouth effect lower edge in the middle part of hinged place it is counterclockwise The guide protrusions of rotation, the second locating part move down under guiding segmental arc effect.

Compared with prior art, the utility model has the following advantages:

1, the utility model provides the foldable stroller with cooperating joint locking structure, is realized by simple structure Folding or be unfolded to vehicle frame, and operation when cooperating joint locking structure not only contributes to facilitate unlock, pass through a step solution The rotation of vehicle frame can be realized in lock, and it is conducive to rotate more smooth, stabilization when vehicle frame relative rotation folds or is unfolded.

2, foldable stroller of the utility model with cooperating joint locking structure is relative to traditional pram folding mechanism Only with single locating part, it can find to have some setbacks during rotating vehicle frame in use, often get stuck, and this Scheme can increase the stability of the steady of rotation process and unlock using double limiting sections, and real by linkage of unlocking part Another locating part is unlocked while unlocking single locating part now, realizes linkage of unlocking, so that structure is more simple, operation is more It is easy.
