Description

Universal rolling wheel that can two-way use

Technical field

The utility model relates to a kind of universal rolling wheel, particularly a kind of universal rolling wheel that is used for the two-way use in front and back on the bodybuilding and entertainment product.

Background technology

As everyone knows, universal rolling wheel is used widely on a lot of bodybuilding and entertainment products owing to can rotate freely around central shaft; , after all requiring departing from initial position, the universal rolling wheel that uses on most of bodybuilding and entertainment products has the function of automatically replying; As the present fashionable world, can body-building again can amusement two skateboards be exactly wherein a kind of; But existing universal rolling wheel in use has the following disadvantages: the one, and after departing from, the universal rolling wheel generation often can not automatically revert to original initial position well, need effect by external force, will influence the result of use of product like this; The 2nd, after existing universal rolling wheel installed and fixed, it can only advance along a specific direction, cannot reversely use, and this also has influence on craftsmenship, interest and the excitant of product use; The deficiency of above-mentioned existence has become a difficult problem in the industry.For this reason, many manufacturers and knowledgeable people research and develop at the problems referred to above, but do not have better products to emerge so far as yet.

Summary of the invention

In order to overcome the above-mentioned disadvantage that existing universal rolling wheel exists, the purpose of this utility model provide a kind of simple and reasonable, processing is easy for installation, it is stable and reliable for performance to automatically reply, can change the direction of motion can two-way use universal rolling wheel.

The technical scheme that its technical problem that solves the utility model adopts, it comprises wheel seat, connecting axle, rolling wheel support, roller, one end of connecting axle is fixedlyed connected with rolling wheel support, roller rollably is arranged on the rolling wheel support, described wheel seat inboard is provided with bearing chamber, and the outside is provided with the elliptical horn mouth, and universal bearing is installed in the bearing chamber, the other end of connecting axle is fixedlyed connected with the universal bearing inner ring, and connecting axle can be along any direction and the angular turn of universal bearing movement locus.

Further preferred version of the present utility model, the centre of described connecting axle is provided with the directive wheel that is complementary with the elliptical horn mouth, and directive wheel can roll along the elliptical horn mouth spigot surface in the wheel seat outside; During original state, truck assembly of fixedlying connected with connecting axle and roller are in the potential energy minimum point place of elliptical horn mouth all the time, when producing deflection, roller drives connecting axle when universal bearing outer ring central shaft is swung, directive wheel rolls along about elliptical horn mouth spigot surface, thereby drive the wheel seat rippling, and generation motive force forward, left and right sides deflection angle is big more, and the restoring force that roller and rolling wheel support produce is also big more; When departing from the initial position angle under external force, roller and rolling wheel support surpass 90 degree, be after directive wheel is crossed elliptical horn mouth spigot surface potential energy peak, rolling wheel support and roller can rotate to and the opposed direction of initial position automatically, and roller just can be realized counter motion.

Further preferred version of the present utility model is provided with spacer between described connecting axle and the directive wheel, can reduce wear.

Further preferred version of the present utility model, described directive wheel is a needle bearing, it is more flexible that roller and rolling wheel support are turned to.

After adopting said structure, owing to adopted the elliptical horn mouth, connecting axle is fixedlyed connected with the universal bearing inner ring, directive wheel rolls along about elliptical horn mouth spigot surface, thereby make roller and rolling wheel support produce bigger restoring force, and can be according to the requirement of different product, moment changes the direction of advance of product, therefore the utility model can be widely used in slide plate, Rocking cycle, scooter, on the multiple body-building recreation products such as breast-stroke car, the product exercise performance is obviously improved, product has more challenge and recreational, increase user's temperament and interest and interest, especially the teenager is had more attraction, play out more style, show more using skill.

The specific embodiment

Fig. 1, Fig. 2 and shown in Figure 3, be a kind of universal rolling wheel specific embodiments that can two-way use provided by the utility model, it comprises wheel seat 6, connecting axle 3, rolling wheel support 2, roller 9, one end of connecting axle 3 is fixedlyed connected with rolling wheel support 2 by screw 1, roller 9 rollably is arranged on the rolling wheel support 2, described wheel seat 6 inboards are provided with bearing chamber 11, the outside is provided with elliptical horn mouth 10, be mounted with universal bearing 7 by jump ring 8 in the bearing chamber 11, the other end of connecting axle 3 is fixedlyed connected with universal bearing 7 inner rings by screw 1.The centre of described connecting axle 3 is provided with the directive wheel 4 that is complementary with elliptical horn mouth 10, is provided with spacer 5 between connecting axle 3 and the directive wheel 4, and directive wheel 4 is preferably selected needle bearing for use, and directive wheel 4 can roll along elliptical horn mouth 10 spigot surfaces in wheel seat 6 outsides.

Rolling wheel support 2 and roller 9 are in elliptical horn mouth 10 spigot surface potential energy minimum point places all the time during the utility model original state, when roller 9 generation deflections drive connecting axles 3 are swung around center, universal bearing 7 outer ring, directive wheel 4 rolls along about elliptical horn mouth 10 spigot surfaces, thereby make wheel seat 6 produce rippling, and generation motive force forward, left and right sides deflection angle is big more, and the restoring force that roller 9 and rolling wheel support 2 produce is also big more.After roller 9 and rolling wheel support 2 depart from the initial position angle under external force and surpass 90 degree, be after directive wheel 4 is crossed the potential energy peak of elliptical horn mouth 10 spigot surfaces, rolling wheel support 2 and roller 9 can rotate to the direction with the initial position opposition automatically, and roller 9 just can be realized counter motion.
