Abstract
The utility model relates to a baby carriage, in particular to an exchanging mechanism of wheels, which comprises a front fork, wheels and a wheel support, and is characterized in that the wheels are arranged on the wheel support through axles, through holes are arranged on the connecting portions of the front fork and the wheel support, fast-disassembling assemblies are respectively arranged on the through holes, the fast-disassembling assemblies are provided with a cam, the cam is provided with a rotation shaft, the rotation shaft is connected with a rod, and the rotation shaft is vertical to the rod, the rod is traversed through the through holes and is connected with a nut which is used as a fastening head in a matching mode, a connecting groove is arranged on the wheel support, a groove which is corresponding to the fast-disassembling assemblies is arranged on a connecting groove, and the groove adapts to the rod. When needing exchanging wheels, the cam is pulled, and the thinner surface of the cam turns to one side of the through holes, which enables the connecting groove to be loosened with the fast-disassembling assemblies, then needed wheels are exchanged, then the cam is pulled again, the thicker surface of the cam turns to one side of the through holes, which enables the connecting groove to be tightly clamped with the fast-disassembling assemblies, thereby completing the exchanging of the wheels. The whole operation is simple and convenient, and can be completed without other tools.
Description
Technical field
The utility model relates to a kind of perambulator, especially relates to a kind of interchange mechanism of pushchair.
Background technology
Perambulator is travelled outdoors for the head of a family looks after children, shopping etc. provides very big convenience, and a feasible child is with at one's side can be so not tired.But because people are in when trip, road conditions have nothing in common with each other, if only use with a kind of wheel, obviously can arrive the bigger damage of wheel, and some situation, its use also can be very effort.Simultaneously, when a wheel was impaired, people also needed it is changed.When traditional wheel will be changed, change the instrument that will make specialty, carry out comparatively complicated work and just can finish, and for some average families, this operation has very big difficulty.After having retrieved association area, this type of optimal design is found to have in the end.
Summary of the invention
The utility model mainly is the technical matters of complicated operation etc. when solving the existing in prior technology wheel and exchanging, and a kind of simple in structure, easy to operate wheel interchange mechanism is provided.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: a kind of wheel interchange mechanism, comprise front fork, wheel and vehicle wheel frame, it is characterized in that described wheel is located on the vehicle wheel frame by wheel, the connecting portion of front fork and vehicle wheel frame is provided with through hole, be respectively equipped with the quick detach assembly on the through hole, described quick detach assembly has a cam, cam is provided with a S. A., this S. A. links to each other with a rod member, both are vertical mutually, this rod member passes through hole and the nut as locking head is connected, described vehicle wheel frame is provided with link slot, link slot is provided with and quick detach assembly corresponding groove, and this groove and described rod member are suitable.When needs exchange wheel, pull cam, the one side that cam is thin turns to through hole one side, make link slot and quick detach assembly unclamp, change the wheel that needs, pull cam again, do thicker one side and turn to through hole one side protruding, make link slot and quick detach assembly clamp, just finished the exchange of wheel.Whole operation is simple and convenient, need be by other instrument.
As preferably, described cam is provided with a handle, and the pivot point far away of cam and the vertical line of rotating shaft are perpendicular to handle axis.This handle makes and more returns convenience, light when pulling cam.When vehicle wheel frame was clamped, the connecting portion of handle and front fork fitted, and when vehicle wheel frame was released, the connecting portion of back handle and front fork was separated, and made more attractive in appearance, the safety of structure.
As preferably, described connecting portion is the cross bar of being located on the wheel carrier, and described through hole is located at the both sides of this cross bar.
As preferably, described link slot bottom fits with cross bar, and the front fork of side and cross bar both sides fits.This method of designing that fits makes structure more firm, attractive in appearance, compact.
As preferably, the rod member between described cam and the link slot is provided with an elastic cushion block.This elastic cushion block can not be damaged it because of too much friction so that cam can directly not contact with link slot on the one hand; Make also that on the other hand structure is more fastening, reliable when connecting.
The beneficial effect that brings of the present utility model is, makes wheel to exchange easily, and simple in structure, safe and reliable.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is a kind of exploded views of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: accompanying drawing 1 is a kind of structural representation of the present utility model; Accompanying drawing 2 is a kind of exploded views of the present utility model.This wheel interchange mechanism, comprise front fork 3, wheel and vehicle wheel frame 1, wheel is located on the vehicle wheel frame by wheel, two through holes about connecting portion on front fork and the vehicle wheel frame cross bar is provided with, be respectively equipped with the quick detach assembly on the through hole, described quick detach assembly has a cam 4, cam is provided with a S. A., this S. A. links to each other with a rod member 6, both are vertical mutually, this rod member passes through hole and the nut 2 as locking head is connected, and cam is provided with a handle, and the pivot point far away of cam and the vertical line of rotating shaft are perpendicular to handle axis.Vehicle wheel frame is provided with link slot, and the both sides of link slot are equipped with and quick detach assembly corresponding groove, and this groove and described rod member are suitable.Link slot cooperates installation with the quick detach assembly after, the link slot bottom fits with cross bar, and the front fork of side and cross bar both sides fits.Rod member between cam and the link slot is provided with an elastic cushion block 5.
When needs exchange wheel, pull cam, the one side that cam is thin turns to through hole one side, make link slot and quick detach assembly unclamp, change the wheel that needs, pull cam again, do thicker one side and turn to through hole one side protruding, make link slot and quick detach assembly clamp, just finished the exchange of wheel.Whole operation is simple and convenient, need be by other instrument.Elastic cushion block has played the effect that comes off of preventing in the process of fastening use.
So the utility model has been realized the quick detach exchange of wheel, and simple in structure, easy to operate, safe, attractive in appearance, reliable
