Abstract
A baby carriage contains a frame which can be folded and unfolded, front-wheel and rear components at the bottom of the frame. The frame contains a front-wheel bracket, a linking end on the front-wheel bracket which can glide along its length direction and a push rod with a rotary lower end on the linking end. The extending direction of rotating axis line of the push rod is consistent with the gliding direction of the linking end. Set a lock on the linking end and a lockhole on the front-wheel bracket. When the frame transfers from unfolding state to folding state, the push rod is firstly pushed to make the vibratory roller driving the lock to make it deviate from the lockhole. Then, push the push rod downward to fold the frame. When it transfers from folding state to unfolding state, the lock locates into the lockhole under the spring elasticity to lock the frame. The operation is very convenient.
Description
Technical field
The present invention relates to a kind of perambulator.
Background technology
In the prior art, perambulator generally includes vehicle frame, be arranged on the front component of the following front portion on the vehicle frame, be arranged on the following rear portion of described go-cart vehicle frame wheel assembly, be used to lock the lockout mechanism of vehicle frame, common described lockout mechanism comprises lockhole, lock dog that is arranged on the vehicle frame and the button that is used for release, described lockout mechanism has release and two states of locking, must make described lock dog between lock-out state and released state, change by pressing described button, operate comparatively loaded down with trivial details.
Summary of the invention
The purpose of this invention is to provide the easy perambulator of a kind of vehicle frame lock mechanism operative.
To achieve the above object, technical scheme of the present invention is: a kind of perambulator, it comprises the vehicle frame with deployed condition and folded state, be arranged on the front component of the front portion, the end of described vehicle frame, be arranged on the wheel assembly at the rear portion, the end of described vehicle frame, described vehicle frame has front-wheel support, can be slidingly arranged in the connection termination on the front-wheel support along the length direction of described front-wheel support, the bottom is arranged on the push rod on the described connection termination rotationally, the bearing of trend of the rotational axis line of described push rod is consistent with the direction of slip of described connection termination, described connection is provided with tapered end on the termination slidably, have lockhole on the described front-wheel support, described tapered end has locking and two states of release, when described tapered end was in the lock state, described tapered end was inserted in the described lockhole; When described tapered end is in released state, described tapered end breaks away from described lockhole, the bottom of described push rod is fixed with eccentric shifting block, when described vehicle frame from deployed condition to the process of folded state conversion, described eccentric shifting block is used to stir described tapered end.
Described tapered end is slidingly arranged on the described connection termination along the direction of axis line perpendicular to front-wheel support.
Described tapered end is provided with spring with described the connection between the termination, described spring makes described tapered end have the trend that stably is in the lock state.
Described front-wheel support is provided with described push rod with paralleling.
The last top of described front-wheel support is set with upper connector, and described upper connector has pilot hole, and described push rod can be inserted in the described pilot hole axially slidably.
Offer the deep-slotted chip breaker that matches with described eccentric shifting block on the described tapered end, described eccentric shifting block is inserted in the described deep-slotted chip breaker rotationally.
Advantage of the present invention is: because the bottom of push rod of the present invention has eccentric shifting block, when vehicle frame from deployed condition when folded state is changed, at first rotating push-rod makes eccentric shifting block stir tapered end, makes tapered end break away from lockhole, promotes the vehicle frame that push rod is a foldable stroller then downwards.When vehicle frame from folded state when deployed condition is changed, only need upwards promote push rod, when the tapered end in the connection termination of push rod lower end was aimed at lockhole, because the elastic force of spring makes tapered end be positioned at the vehicle frame that lockhole promptly locks perambulator, it was comparatively convenient to operate.

The specific embodiment
As accompanying drawing 1 to a kind of perambulator shown in the accompanying drawing 8, it comprises the vehicle frame 3 with deployed condition and folded state, be arranged on the front component 11 of the front portion, the end of described vehicle frame 3, be arranged on the wheel assembly 12 at the rear portion, the end of described vehicle frame 3, described vehicle frame 3 has front-wheel support 4, can be slidingly arranged in the connection termination 6 on the front-wheel support 4 along the length direction of described front-wheel support 4, the bottom is arranged on the push rod 1 on the described connection termination 6 rotationally, the bearing of trend of the rotational axis line of described push rod 1 is consistent with the direction of slip of described connection termination 6, be provided with tapered end 8 slidably on the described connection termination 6, have lockhole 10 on the described front-wheel support 4, described tapered end 8 has locking and two states of release, when described tapered end 8 was in the lock state, described tapered end 8 was inserted in the described lockhole 10; When described tapered end 8 is in released state, described tapered end 8 breaks away from described lockhole 10, the bottom of described push rod 1 is fixed with eccentric shifting block 7, when described vehicle frame 3 from deployed condition to the process of folded state conversion, described eccentric shifting block 7 is used to stir described tapered end 8.
Described tapered end 8 is slidingly arranged on the described connection termination 6 along the direction of axis line perpendicular to front-wheel support 4.
Described tapered end 8 is provided with spring 9 with described the connection between the termination 6, described spring 9 makes described tapered end 8 have the trend that stably is in the lock state.
Described front-wheel support 4 is provided with described push rod 1 with paralleling.
The last top of described front-wheel support 4 is set with upper connector 2, and described upper connector 2 has pilot hole, and described push rod 1 can be inserted in the described pilot hole axially slidably.
Offer the deep-slotted chip breaker 5 that matches with described eccentric shifting block 7 on the described tapered end 8, described eccentric shifting block 7 is inserted in the described deep-slotted chip breaker 5 rotationally.
When perambulator by deployed condition when folded state is changed, at first rotating push-rod 1, the eccentric shifting block 7 that is fixed on described push rod 1 bottom also rotates thereupon, eccentric shifting block 7 pushes against on tapered end 8 when rotating, stir tapered end 8 and break away from lockhole 10, even lockout mechanism release, promote push rod 1 this moment downwards, the connection termination 6 that drives push rod 1 end moves down, owing to connect between termination 6 and the rear wheel support 13 and be connected with connecting rod 14, connecting rod 14 makes front-wheel support 4 folding with rear wheel support 13 along with connecting moving down of termination 6, and this moment, perambulator was positioned at folded state.
When perambulator by folded state when deployed condition is changed, at first upwards spur push rod 1, make push rod 1 end connect termination 6 along with moving up, owing to connect between termination 6 and the rear wheel support 13 and be connected with connecting rod 14, make front-wheel support 4 and rear wheel support 13 relative expansion,, insert in the lockholes 10 because the elastic force of spring 9 promotes tapered end 8 when the tapered end 8 in the connection termination 6 of push rod 1 end slides into when aiming at lockhole 10, be the lockout mechanism locking, this moment, perambulator was positioned at deployed condition.
