The present invention relates to a kind of entertainment product, and in particular, to a feet-swinging-type roller skate of concave plastic panel utilizing front and rear two feet cross swinging toward both sides to make it forward.
Although the existing feet-swinging-type roller skate has an ingenious structure and strong entertaining, there is also a room for improvement in appearance and manufacturing technique, which mainly has drawbacks such as the structure is more complex and the manufacturing is difficult etc.
The object of the present invention is to provide a feet-swinging-type roller skate of concave plastic panel, which structure is more simple, which manufacturing technique is more simple and convenient, which appearance is more perfect.
In order to solve the aforementioned technical problems, the technical solutions provided by the present invention are:
A feet-swinging-type roller skate of concave plastic panel, comprising a concave plastic panel and universal wheels, said concave plastic panel is in the shape of a concave-shaped top, the universal wheels are respectively mounted at the lower ends of the concave front top and rear top of the concave plastic panel, two feet-swinging-type roller skates of concave plastic panel are matched in pairs to use.
Further, the concave front top and rear top of said concave plastic panel each has one perforation for up and down, a downward protrusion of pot bottom shape is disposed below the perforation of the concave plastic panel, a connecting bolt of the top of said universal wheel passes through the perforation, a nut coordinated with said connecting bolt screws the bolt.
Further, a counterbore is disposed on the upper portion of said perforation, said nut falls into the counterbore after screwing.
Further, the feet-swinging-type roller skate of concave plastic panel futher comprising a cover, said cover places on said counterbore.
Further, said cover is a plastic cover.
Further, said concave plastic panel is injection molded.
Further, the concave front top and rear top of said concave plastic panel tilt slightly toward the front down.
Further, said concave plastic panel is an injection piece that the side thereof is concave shape and the overlook shape of the panel surface is olive shape, longitudinal and transverse reinforcing ribs are distributed on the whole bottom of said concave plastic panel.
Further, a bearing is inlaid into the top of the wheel fork of said universal wheel, one bolt is cup jointed inside the bearing bore, a PU wheel is connected to the wheel fork, one said universal wheel is connected with the perforation carrying a counterbore of the concave front top of said concave plastic panel via a nut, one said universal wheel is connected with the perforation carrying a counterbore of the concave rear top of said concave plastic panel via a nut, two said universal wheels form the same forward tilt angle with said concave plastic panel after connecting.
Further, said plastic cover is a plastic cover of dome shape, one said plastic cover is inlaid in the counterbore of the concave front top of the said concave plastic panel, the other one said plastic cover is inlaid in the counterbore of the concave rear top of said concave plastic panel.
The beneficial effects of the present invention are: the side of the concave plastic panel of the feet-swinging-type roller skate of concave plastic panel is a concave shape design, the overlook shape of the panel surface of the concave plastic panel is olive shape, such that the appearance of the feet-swinging-type roller skate of concave plastic panel is unique and beautiful and has modern feeling, and the production process is simple. The foothold of the feet-swinging-type roller skate of concave plastic panel is low off the ground, therefore which safety is good, which is easy to learn, and which has very strong interesting when playing.
In the drawings: 1-concave plastic panel, 2-universal wheel, 3-plastic cover.
The present invention will be illustrated below in more details in combination with embodiments and appended drawings for the purpose of making objects, technical solutions and advantages of the present invention more clear and obvious. It should be understood that specific embodiments illustrated herein are simply used to explain the present invention but not used to define the present invention.
The object of the present invention is achieved the followings: a feet-swinging-type roller skate of concave plastic panel comprises a concave plastic panel, universal wheels and plastic covers, two feet-swinging-type roller skates of concave plastic panel are front and rear matched in pairs to use, the concave plastic panel of the feet-swinging-type roller skate of concave plastic panel is in the shape of a concave-shaped top which is plastic injection molded, the concave front top and rear top of the concave plastic panel all tilt slightly toward the front down, the concave front top and rear top of the concave plastic panel each has one perforation carrying a counterbore, the concave front top and rear top of the concave plastic panel have downward protrusions of pot bottom shape at the bottom of the positions of perforations carrying counterbores, perforations carrying counterbores of the concave front top and rear top of the concave plastic panel each connects one universal wheel, two universal wheels are screwed into perforations carrying counterbores of the concave front top and rear top of the concave plastic panel by the connecting bolts of the tops of the universal wheels coordinating with nuts, and making the screwing places between nuts and the connecting bolts of the tops of the universal wheels locate in the counterbores of the concave front top and rear top of the concave plastic panel, and inlaying two plastic covers in the two counterbores.
The present invention will be more specifically illustrated below with reference to the appended drawings. As shown in
Said concave plastic panel 1 is an injection piece that the side thereof is concave shape and the overlook shape of the panel surface is olive shape, the concave front top and rear top of said concave plastic panel 1 all tilt slightly toward the front down, the concave front top and rear top of said concave plastic panel 1 each has one perforation carrying a counterbore, the concave front top and rear top of said concave plastic panel 1 have downward protrusions of pot bottom shape at the bottom of the positions of perforations carrying counterbores, longitudinal and transverse reinforcing ribs are distributed on the whole bottom of said concave plastic panel 1, perforations carrying counterbores of the concave front top and rear top of said concave plastic panel 1 are used to connect universal wheels.
Said universal wheel 2 is a universal wheel that a bearing is inlaid into the top of the wheel fork, one bolt is cup jointed inside the bearing bore, a PU wheel is connected to the wheel fork, one said universal wheel 2 is connected with the perforation carrying a counterbore of the concave front top of said concave plastic panel 1 via a nut, one said universal wheel 2 is connected with the perforation carrying a counterbore of the concave rear top of said concave plastic panel 1 via a nut, two said universal wheels 2 form the same forward tilt angle with said concave plastic panel 1 after connecting.
Said plastic cover 3 is a plastic cover of dome shape, one said plastic cover 3 is inlaid in the counterbore of the concave front top of said concave plastic panel 1, one said plastic cover 3 is inlaid in the counterbore of the concave rear top of said concave plastic panel 1.
