Summary of the invention
The utility model object is: provide a kind of Back of perambulator stepless regulation structure, it can realize the angular adjustment of back rest by the distance between adjustment accommodation zone fixed end and electrodeless regulating control, and structure is simple, easy to operate, cost is also lower, and can realize the adjustment of multi-angle position.
The technical solution of the utility model is: a kind of Back of perambulator stepless regulation structure, comprise vehicle frame, the back rest that cushion frame and lower end are connected with cushion frame rear end thereof, be provided with accommodation zone to the bilateral symmetry of described vehicle frame, one end and the vehicle frame of accommodation zone are connected and fixed, the other end that back rest is provided with for accommodation zone wears, stretch out and stepless regulator for locking accommodation zone, described stepless regulator comprises the pedestal be arranged on back rest, described pedestal has the through slot worn for accommodation zone and the guide groove communicated with this through slot, the roller pin that can roll along it is provided with in described guide groove, in the through slot that described accommodation zone is located in pedestal and accommodation zone at least partly can with roller pin interference fit, stepless regulator realizes locking the clamping of accommodation zone by the interference fit of roller pin and accommodation zone, and then realize the angular adjustment of back rest.
Further, described through slot is triplet type, it has the first groove portion and the second groove portion that stretch into for both sides accommodation zones respectively and closes up rear the 3rd groove portion simultaneously worn for both sides accommodation zone, described through slot only the 3rd groove portion is communicated with guide groove, and in the axial direction of guide groove internal trolley pin and the 3rd groove portion, the bearing of trend of accommodation zone is arranged vertically.Wherein, the outer peripheral face that described roller pin coordinates with accommodation zone has annular knurl.
Further, described back rest is in anti-card division that 135 degree of-155 accommodation zone part being positioned at pedestal the 3rd groove portion when spending is thinner thickness, that cannot be established by roller pin card, and the remainder of accommodation zone except anti-card division is the clamping part that thickness is thicker, can be clamped by roller pin.
The utility model has the advantages that:
1, the angular adjustment of the utility model by regulating the distance between accommodation zone fixed end and electrodeless regulating control can realize back rest, structure is simple, and easy to operate, cost is also lower, and can realize the adjustment of multi-angle position.
2, in the utility model, the accommodation zone of both sides is clamped by same stepless regulator, is convenient to backrest angle adjustment operation, avoids both sides when clamping respectively, causes back rest unstable, improve simple operation and stability because of the inconsistent of adjustment.
3, the outer peripheral face that in the utility model, roller pin coordinates with accommodation zone has annular knurl, and the setting of annular knurl can increase friction force when itself and accommodation zone interference fit, avoids both automatically to loosen because of skidding.
4, in the utility model, when back rest regulates at 135 degree ~ 155 degree, the anti-sticking portion of accommodation zone is positioned at the 3rd groove portion, now roller pin cannot block accommodation zone, avoid this interval to the least favorable state of turning over stability after car load, and the remainder of accommodation zone is the clamping part can established for roller pin card, therefore the angle of back rest beyond 135 degree ~ 155 degree can realize any angle locking, and then the multi-angle realizing back rest regulates.
