Fig. 1 is the utility model structural representation.

Fig. 2 is the utility model front elevation.

Detailed description of the invention

As depicted in figs. 1 and 2, a kind of multi-functional rear wheel seat device, comprise rear foot tube 1, step rivet 2, bullet pin 3, rear wheel seat 4, rivet 5, damping spring 6, described rear wheel seat 4 upper ends are provided with anti-rotation bayonet socket 7, side is provided with and plays pin-and-hole 9 and rivet hole 8, and described rear foot tube 1 is provided with step rivet 2 and bullet pin 3, and step rivet 2 is positioned at bullet pin 3 tops, described rear foot tube 1 stretches into rear wheel seat 4, and rear foot tube 1 bottom is connected by damping spring 6 with rear wheel seat 4 inner side diapires.Described damping spring 6 tops are positioned at rear foot tube 1 inside, and damping spring 6 upper ends utilize rivet 5 to be fixed on rear foot tube 1 by rivet hole 8, and lower end and rear wheel seat 4 inner side diapires are fixed.Described step rivet 2 adapts with anti-rotation bayonet socket 7, and bullet pin 3 adapts with bullet pin-and-hole 9.Described anti-rotation bayonet socket 7 is " U " type shape, and anti-rotation bayonet socket 7 upper ends are opened wide, and screw and coordinate with step rivet 2.Rear foot tube 1 diameter that the utility model is preferably applied is 16mm.

Principle narration: rear foot tube 1, step rivet 2, bullet pin 3 are assembled into assembly, utilize step rivet 2 and the anti-rotation bayonet socket 7 of rear wheel seat 4 to assemble, realization prevents 360 degree rotations of rear wheel seat 4, simultaneously by elasticity and the perforation limit function of bullet pin 3, realizes the upper and lower spacing and removable function of rear wheel seat 4.Fill pin pipe 1, rear wheel seat 4, damping spring 6 by rivet 5 and be linked and packed, realize shock-absorbing function, realize the switching of removable and shock-absorbing function, thereby meet different functional requirements.

The utility model, by adding the spacing of step rivet of riveting 2 and wheel seat breach, is realized easily pipe 360 degree rotary stoppers in wheel seat, thereby has been reduced greatly cost of parts, has simplified assembly technology.In addition, this utility model newly removable, the large Function Integration Mechanism of damping two in one, realize more flexibly the selection of client and customer's difference in functionality.

Above content is only to the utility model structure example and explanation; affiliated those skilled in the art make various amendments to described specific embodiment or supplement or adopt similar mode to substitute; only otherwise depart from the structure of utility model or surmount this scope as defined in the claims, all should belong to protection domain of the present utility model.
