Abstract

The utility model discloses a separate type roller skating base, which comprises a bracket and a plurality of wheel holes arranged at the bottom of the bracket, wherein the bracket comprises a rear fixed bracket used for being connected with a shoe body and a front movable bracket hinged with the rear fixed bracket; because the bottom of the front movable support is provided with three wheels, the rear fixed support hinged with the front movable support is provided with one wheel, when the roller skate is started up with higher speed, the rear fixed support rotates around the front movable support to drive the fourth wheel to be separated from the ground, at the moment, the three wheels work to increase the pedaling distance and increase the speed, when the roller skate slides at high speed, the rear fixed support returns, and the fourth wheel and the three wheels on the front movable support slide on the ground together, thereby ensuring ideal balance.

Description

Separate type skidding base

Technical field

The utility model relates to a kind of skidding base of roller skate.

Background technology

Roller skate mainly is made up of skidding base and the footwear body that is connected on the skidding base, and skidding base bottom is fixed with a plurality of holes of taking turns that form a line, and wheel is equipped with wheel by wheel shaft in the hole, and the quantity of wheel is generally three or four.Because the people is when quickening roller skate, tiptoe will down be exerted oneself, and heel is liftoff, forms an action of pedaling pin, farthest pedals straight shank.When the wheel quantum count is three, more favourable when roller skate is quickened to start, can strengthen the distance of pedaling pin, and the sense of equilibrium is not good when sliding at a high speed; And the wheel quantum count has the preferable sense of equilibrium when being four when sliding at a high speed, but effect is undesirable when quickening to start.

The utility model content

The purpose of this utility model is to provide a kind of separate type skidding base that possesses the desirable speed and the sense of equilibrium.

The technical scheme that its technical problem that solves the utility model adopts is: separate type skidding base, the a plurality of holes of taking turns that comprise support and be installed on frame bottom, described support comprises the preceding travel(l)ing rest that is used for the back fixed support that is connected with the footwear body and is articulated and connected with the back fixed support, be provided with return spring between preceding travel(l)ing rest and the back fixed support, before the travel(l)ing rest bottom level be arranged with the first round, second and take turns and third round, back fixed support is provided with four-wheel.

Wherein, described four-wheel is installed on fixed support rear end, back, and the front end of back fixed support front end and preceding travel(l)ing rest is hinged, and the two ends of return spring are separately fixed at the middle part of back fixed support and preceding travel(l)ing rest.

In addition, between the center vertical line between the pin joint on the described preceding travel(l)ing rest was taken turns in the first round and second, second before an end of return spring is fixed on the travel(l)ing rest taken turns the place.

The beneficial effects of the utility model are: three wheels are arranged at preceding travel(l)ing rest bottom, the back fixed support hinged with preceding travel(l)ing rest is provided with a wheel, when roller skate was quickened to start, back fixed support rotated around preceding travel(l)ing rest and drives four-wheel disengaging ground, and this moment, three wheels were in work, can strengthen the distance of pedaling pin, raising speed, when sliding at a high speed, back fixed support return, sliding in the ground that coexists of three wheels on four-wheel and the preceding travel(l)ing rest, guarantees the desirable sense of equilibrium.

Description of drawings

Fig. 1 is the structural representation of the utility model when quickening to start;

Fig. 2 is the structural representation of the utility model when sliding at a high speed.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in further detail.

With reference to Fig. 1, shown in Figure 2, separate type skidding base, the a plurality of wheels that comprise support and be installed on frame bottom, described support comprises the preceding travel(l)ing rest 11 that is used for the back fixed support 12 that is connected with footwear body 3 and is articulated and connected with back fixed support 12, be provided with return spring 5 between preceding travel(l)ing rest 11 and the back fixed support 12, wherein, preceding travel(l)ing rest 11 bottom levels are arranged with the first round 41, second takes turns 42 and third round 43, back fixed support 12 is provided with four-wheel 44, described four-wheel 44 is installed on fixed support 12 rear ends, back, the front end of back fixed support 12 front ends and preceding travel(l)ing rest 11 is hinged, pin joint is taken turns in the first round 41 and second between 42 the center vertical line, i.e. optional position between the vertical line at two centers, one end of return spring 5 is fixed on the middle part of back fixed support 12, and second before the other end is fixed on the travel(l)ing rest 11 taken turns 42 places.

When roller skate is quickened to start, back fixed support 12 rotates and then drives four-wheel 44 around preceding travel(l)ing rest 11 and breaks away from ground, have only three wheels in ground taxi this moment, can strengthen the distance of pedaling pin, raising speed, when sliding at a high speed, back fixed support 12 return under the effect of return spring 5, sliding in four-wheel 44 and three wheels on the preceding travel(l)ing rest 11 ground that coexists, guarantees the desirable sense of equilibrium.

The foregoing description is the principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used to limit the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
