Abstract
The invention discloses an auxiliary wheel structure, and belongs to the technical field of bicycle auxiliary devices. The auxiliary wheel structure comprises pivot arms and adjusting components. Screw holes are formed in the pivot arms. The pivot arms are connected with a bicycle in a pivot mode. Each adjusting component mainly consists of screw teeth, a control element, a connecting rod and a rigid adjusting element. One end of each adjusting component penetrates through a screw hole through the screw teeth and is movably connected with each pivot arm in a sleeved mode, and the other end of each adjusting component is provided with an auxiliary wheel. The auxiliary wheel structure has the advantages of enabling a user to adjust in a gradual mode, and reducing dependence on the auxiliary wheel when the user is in a process of learning how to ride the bicycle.
Description
Technical field
The present invention relates to a kind of auxiliary wheel structure, on especially applicable bicycle, belong to bicycle auxiliary device technical field.
Background technology
Children are at the awheel initial stage of study, often can because can't balance falling injuredly, can significantly lower children to learning awheel interest.Present on the market kiddie car auxiliary wheel, it mainly designs is for the assisting child Fast Learning, avoids that to cause children to fall down injured because car body rocks.The design of the auxiliary wheels of tradition is often only simply loaded onto the auxiliary wheel carrier with auxiliary wheel in car body trailing wheel two sides, keeps driving balance with assisting child.Yet should the tradition auxiliary wheel carrier design, have following disappearance: 1. use for a long time, the distortion that easily gets loose of supplemental support wheel carrier and car body spiral shell knot place makes the auxiliary wheel at all can't close proximity to ground and do not bring into play effect; 2. children are in learning process, and each period is different to the demand of auxiliary wheel, and traditional fixed auxiliary wheel can't be with the required angle of inclination of adjusting of user; 3. this kind auxiliary wheel rigidity is strong, therefore when bicycle is turned fast, often fall down because the bicycle crank causes to overturn; 4. after in a single day learning, must pull down auxiliary wheel, its product value added is extremely low.
Summary of the invention
For above-mentioned existing technical matters, the invention provides a kind of auxiliary wheel structure, in the process of learning riding bicycle, allow the user adjust in progressive mode, reduce the dependence to auxiliary wheel.
The present invention is achieved through the following technical solutions for achieving the above object: a kind of auxiliary wheel structure comprises driving arm and adjusts member; Driving arm has screw, and is articulated on bicycle; Adjust member and mainly be made of thread, control element, connecting rod and rigidity adjustment element, the one end passes the screw pivot bush unit in driving arm by thread, and the other end is provided with auxiliary wheel.
Further, rigidity adjustment element is spring or cylinder.
The invention has the beneficial effects as follows: can adjust by adjusting member, avoid crossing the distortion that gets loose of spiral shell knot of a specified duration place because of the auxiliary wheel period of service.Can solve and adjust arbitrarily the angle of inclination because children's demand is different.Adjusting the rigidity adjustment unit of member can avoid falling down because the bicycle crank overturns children.But the driving arm that mat is connected with car body improves the value added of product to adjust the location of auxiliary wheel.
Description of drawings
Fig. 1 is structural representation of the present invention
In figure: 1, driving arm, 11, screw, 2, adjust member, 21, thread, 22, control element, 23, connecting rod, 24, rigidity adjusts element, 3, bicycle, 4, auxiliary wheel.
The specific embodiment
The invention will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, the present invention includes driving arm 1 and adjustment member 2; Driving arm 1 has screw 11, and is articulated on bicycle 3; Adjust member 2 and mainly be made of thread 21, control element 22, connecting rod 23 and rigidity adjustment element 24, the one end passes screw 11 pivot bush units in driving arm 1 by thread 21, and the other end is provided with auxiliary wheel 5; Control element 22 is adjusted rigidity by the screw thread on thread 21 and is adjusted element 24 or connecting rod 23, and for the activity nargin of adjusting member 2 or change relative position, rigidity is adjusted element 24 and generally is preferably spring or cylinder etc.
Wherein, adjust member 2 and more can comprise a nut block, can prevent that rigidity adjustment element 24 from getting loose, and non-return effect is arranged.Control element 22 is adjusted the nargin of element 24 in order to adjust rigidity, so that the activity nargin of bicycle 3 and auxiliary wheel 4 to be provided, and the thread 21 of control element 22 in order to adjust connecting rod 23, change the position for adjusting member 2.
