Description
Technical field
The utility model relates to child's bicycle field, particularly a kind of jockey pulley bar for child's bicycle.
Background technology
Children for learning generally needs by bike by other people's auxiliary balance, and in this case, auxiliary people is very arduous, and in the process of begining to learn riding bicycle, it is very common thing that wrestling is fallen, and particularly for children, has certain potential safety hazard.For this reason, market has occurred some auxiliary devices, modal is be installed on the less auxiliary wheel of two of child's bicycle trailing wheel both sides by jockey pulley bar, and when riding bicycle, auxiliary wheel can support to ground, avoids falling.But problem is, although this auxiliary wheel can be avoided falling, if road surface is not too smooth or when turning more anxious, auxiliary wheel can occur to tilt or tiltedly askewly to support on ground.The jockey pulley bar of prior art generally only adds simple reinforced rib on jockey pulley bar, as the reinforced rib of the both sides reinforced rib at jockey pulley bar or the side added with triangle at jockey pulley bar, and the impulsive force of jockey pulley bar faced by ground is very large when turning greatly, jockey pulley bar is easy to deform, the simple reinforcing rib structure of prior art can not meet the bending strength requirement of jockey pulley bar, after jockey pulley bar deforms, there is certain potential safety hazard, easily the accidents such as overturning occur.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of bending strength of all directions all fine, and easy to make, the safe and reliable jockey pulley bar for child's bicycle.
The technical scheme in the invention for solving the above technical problem is: a kind of jockey pulley bar for child's bicycle, comprise the jockey pulley bar body of integral type bending forming, described jockey pulley bar body comprises mobile jib, one end of described mobile jib is upwards bent to form the first connecting portion be connected with vehicle frame, the other end of described mobile jib is bent to form the second connecting portion for being connected with jockey pulley downwards, one side of described mobile jib is bent to form the first flange downwards, and the first described flange extends upwardly to the end of the first connecting portion along the side of the first connecting portion, the opposite side of the first described connecting portion is provided with the second flange of bending downwards, another side of described mobile jib is upwards bent to form the first floor, and the limit, upper end of the first described floor and the first described connecting portion are welded and fixed, the second described connecting portion forms the second floor near the side forward fold of the first floor, and the limit, upper end of the second described floor and described mobile jib are welded and fixed.
Compared with prior art, the utility model has the advantage of: this jockey pulley bar is integral type bending forming, and one end of mobile jib is upwards bent to form the first connecting portion be connected with vehicle frame, the other end of mobile jib is bent to form the second connecting portion for being connected with jockey pulley downwards, one side of mobile jib is bent to form the first flange downwards, and the first flange extends upwardly to the end of the first connecting portion along the side of the first connecting portion, the opposite side of the first connecting portion is provided with the second flange of bending downwards; First flange and the second flange not only can strengthen the intensity of the first connecting portion, and can form the draw-in groove for matching to the relevant installation position of vehicle frame between the first flange and the second flange, more convenient to install, location.Another side of mobile jib is upwards bent to form the first floor, and the limit, upper end of the first floor and the first connecting portion are welded and fixed, and the second connecting portion forms the second floor near the side forward fold of the first floor, and the limit, upper end of the second floor and mobile jib are welded and fixed.Like this, utilize the setting of the first floor and the second floor, further enhance the intensity of side, prevent obstacle or turn time in the face of jockey pulley bar impact and produce jockey pulley bar distortion, and after bending, the limit, upper end of the first floor and the first connecting portion are welded and fixed, the limit, upper end of the second floor and mobile jib are welded and fixed, easy to make, cost is low, and the use of jockey pulley bar is more safe and reliable.
As preferably, the limit, upper end of the first described floor is a hypotenuse, and hypotenuse reduces downwards gradually from limit, upper end.The first described floor is vertical with described mobile jib to be arranged, and is provided with the first breach near the first connecting portion place between the first described floor and mobile jib.Like this, the structure of the first floor is more reasonable, good looking appearance, and keypoint part obtains actv. emphasis and strengthens, and the first breach of setting can effectively be avoided interfering during welding.
As preferably, the limit, lower end of the second described floor is a hypotenuse, and hypotenuse upwards reduces gradually from the second connecting portion.The second breach is provided with near the second connecting portion place between the second described floor and described mobile jib.Like this, the structure of the second floor is more reasonable, good looking appearance, and keypoint part obtains actv. emphasis and strengthens, and the second breach of setting can effectively be avoided interfering during welding.
As preferably, the first described connecting portion is provided with waist shaped hole.Like this, convenient adjustment.
As preferably, the second described connecting portion place is provided with two circular holes be connected.Like this, convenient adjustment.
