Description
Technical field
The utility model relates to a kind of children trolley, particularly a kind of children trolley with turning joint.
Background technology
Modern society, when most of heads of a family go out the band infant, can use children trolley, and it can effectively reduce the time that need to embrace the child while going out, alleviates the head of a family's burden.Therefore, the range of use of children trolley is more and more extensive.
In order to meet the comfort level of baby in car and to carry out conveniently, carriage for children has certain volume and longer handle, but during storage, the space taken is larger.In city, people go on a journey and generally can drive, and living space is all comparatively precious, and this just needs children trolley when storage, and the space taken is the smaller the better.
In order to be convenient for carrying and to store, the vehicle body of existing children trolley and handle can be drawn in, can when storage, effectively reduce the space that go-cart takies.Therefore, there is the researcher that a kind of retracting structure is provided, the patent documentation that notification number is CN201520324U discloses a kind of baby-carrier folding joint, comprise: an articulation mechanism, there is a upper and lower vehicle frame joint be connected with upper and lower vehicle frame and trailing wheel vehicle frame respectively and trailing wheel vehicle frame joint, also respectively having one can be arranged into collinear breach in these outsides, vehicle frame joint, and inside is hidden and is provided with a gear cluster; And a control mechanism, there is the slide block of a scalable displacement,, make with the breach clip in each vehicle frame joint or separate, and can make vehicle frame launch or fold to drive the block of another scalable displacement by a linkage rod group.This utility model is by above combination, vehicle frame launched or while folding, action is synchronously coherent, and can automatically lock while launching so that easy and simple to handle fast.
Although above utility model provides the cart structure that can fold, but while launching location, only the cooperation by breach and clip positions, vehicle frame is after launching for a long time or folding, will certainly because of the wearing and tearing of clip, cause locating unstable, thereby cause the body structure reliability of children trolley to reduce.
The utility model content
The utility model provides a kind of children trolley with turning joint, to solve existing children trolley, only by the cooperation of breach and clip, position, the positioning element contact surface is little, make to locate unstable, and after long-time expansion or folding, clip can wear and tear and the stability of location is further descended, and even possibly can't realize the problem of location.
A kind of children trolley with turning joint, comprise the upper and lower vehicle frame joint be connected with upper and lower vehicle frame respectively, be provided with a spline between upper and lower vehicle frame joint, upper vehicle frame is provided with the first keyway in joint, lower vehicle frame is provided with the second keyway in joint, and described spline has the locking bit simultaneously engaged with the first keyway and the second keyway;
Also be provided with the driver train for promoting described spline separating lock location and the response agency that makes described spline.
The location that the utility model carries out upper and lower vehicle frame joint by spline structure coordinates, and coordinates stable and reliable.And be provided with driver train and response agency, driver train, by driving spline separating lock location, makes movable cooperation the between vehicle frame joint and lower vehicle frame joint, bent between the two, thereby complete, returns the vehicle to the garage and knock off; When launching vehicle frame, when upper vehicle frame joint and lower vehicle frame joint are stretched over position location, described response agency will promote spline and return to locking bit, thereby again realize going up the heavy keying fit between vehicle frame joint and lower vehicle frame joint.
Manufacture and install for convenient, preferred, described upper and lower vehicle frame joint all has the housing of cup-shaped, and mutually fastens and form container cavity, between upper and lower vehicle frame joint by the hinged cooperation of rotating shaft.
Preferably, described driver train comprises:
Be arranged in the vehicle frame joint for promoting the joint slide block of spline axial motion;
The bracing wire be connected with described joint slide block.
During use, by bracing wire driving joint slipper push spline, move axially, thereby realize spline separating lock location.
Preferably, be provided with the chute coordinated with described joint slide block in upper vehicle frame joint, in described chute, with the inclined-plane slideway, described joint slide block is provided with the inclined-plane matched with described inclined-plane slideway.By in upper vehicle frame joint, the inclined-plane slideway being set, and the inclined-plane coordinate with described inclined-plane slideway is set at the joint slide block, thus bracing wire at spline diameter when pulling the joint slide block to move, the joint slide block can move to the promotion spline at castellated shaft.
Preferably, described response agency is for being arranged on the IA retracing spring of lower vehicle frame, and this retracing spring and described joint slide block are resisted against respectively the axial two ends of spline.When driver train drives spline separating lock location, described spline compression reseting spring, upper vehicle frame joint can be descended the bending of vehicle frame joint relatively.When upper vehicle frame joint and lower vehicle frame joint are stretched over position location, make, retracing spring promotes spline and comes back to locking bit, thereby again realizes the heavy keying fit between upper vehicle frame joint and lower vehicle frame joint.
Install and manufacture for convenient, preferred, the middle part of described joint slide block has bar hole, and the joint slide block is enclosed within described rotating shaft by this bar hole.
Preferably, described spline and retracing spring all are enclosed within described rotating shaft.
For can be quick, adjust easily upper and lower vehicle frame joint to position location, preferred, described upper vehicle frame joint is provided with the first position block, corresponding, be provided with the second block matched with the first position block on lower vehicle frame joint.While being stretched over location in upper and lower vehicle frame joint, described the first position block and second block are inconsistent, while preventing that upper and lower vehicle frame joint from adjusting contraposition, cross position location.
In order to prevent that spline enters the vehicle frame joint when the bending of upper and lower vehicle frame joint does not put in place, described spline non-centrosymmetry, the facewidth of at least one key tooth is greater than all the other key teeth.
Be greater than all the other key teeth by the facewidth that a key tooth is set, thereby make described spline only when position location, retracing spring could push spline upper vehicle frame joint.
The beneficial effects of the utility model:
Children trolley with turning joint of the present utility model, the location of carrying out upper and lower vehicle frame joint by spline structure coordinates, and coordinates stable and reliable.And be provided with driver train and response agency, driver train, by driving spline separating lock location, makes movable cooperation the between vehicle frame joint and lower vehicle frame joint, bent between the two, thereby complete, returns the vehicle to the garage and knock off; When launching vehicle frame, when upper vehicle frame joint and lower vehicle frame joint are stretched over position location, described response agency will promote spline and return to locking bit, thereby again realize going up the heavy keying fit between vehicle frame joint and lower vehicle frame joint.
