Abstract

The utility model provides a safe roller skate, wherein the lower part of a skate frame is connected with a pulley, and the pulley is a non-return wheel. The instable gravity centre during the retreating of the roller skate provided by the utility model is solved by virtue of the non-return wheel, and the return of a beginner during skating is prevented by virtue of a non-return principle, thus effectively improving the safety of skating. The safe roller skate is convenient and practical.

Description

Safe roller skate

Technical field

The utility model relates to a kind of roller skate, is specifically related to a kind of safe roller skate.

Background technology

Along with development of times, roller skating becomes one of leisure mode loved by all in people's daily life gradually, especially for the teenager, is not only a forms of motion that improves the health, and also becomes a kind of trend of fashion.But present common roller skate, pulley can be according to clockwise or motion counterclockwise, namely can realize the purpose of advancing or retreating by foot-operated roller skate.But for the beginner, very easily cause the underfooting to skid when retreating, can cause falling down of back backstroke during crank, have certain potential safety hazard, also directly caused the part teenager to abandon this motion.

The utility model content

At above problems of the prior art, the utility model provides a kind of security good, easy and simple to handle safe roller skate.

The utility model is achieved through the following technical solutions:

Safe roller skate, the shoe rack bottom connects pulley, the anterior pulley that connects of described shoe rack is non-return the wheel, described non-return the wheel comprises interior wheel and foreign steamer, foreign steamer is internally wheel motion mutually, wheel is provided with non-return seat in described, and the foreign steamer inner ring is provided with check sheet, and described check sheet is inclined to the obtuse angle form in the direction of the clock and arranges;

Or non-return the wheel be unidirectional tooth ratch, and the gear teeth are inclined to the acute angle form in the direction of the clock and arrange.

The beneficial effects of the utility model are: the crank when adopting non-return mode of taking turns to use roller skate to retreat, and utilize non-return principle to prevent that the beginner from driving in the wrong direction when sliding, improved the security of sliding effectively, convenient and practical.

Description of drawings

Fig. 1 is overall structure schematic diagram of the present utility model;

Fig. 2 is the non-return structural representation of taking turns;

Fig. 3 is the non-return structural representation of taking turns two.

Among the figure: 1 is shoe rack; 2 is pulley; 3 is interior wheel; 4 is foreign steamer; 5 is non-return seat; 6 is check sheet; 7 are non-return the wheel.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further details.

The utility model provides a kind of safe roller skate, shoe rack 1 bottom connects pulley 2, the safety problem that crank causes when preventing from retreating, the utility model employing is non-return takes turns 7 as pulley 2 uses, in general, the front-wheel of roller skate is driving wheel, and the pulley 2 that therefore will have non-return function is located at the shoe rack front portion.

Specifically, the non-return wheel can adopt multiple mode to realize non-return function.The utility model is described below two kinds:

As shown in Figure 2, pulley 2(is driving wheel especially) directly adopt unidirectional tooth ratch, the gear teeth are inclined to the acute angle form in the direction of the clock and arrange.The acute angle of the gear teeth can not influence the function that it is advanced when moving ahead, if but want to retreat, then the acutangulate gear teeth carry out counter motion, and its wedge angle can produce greatly friction with ground, and to reduce astern speed, directly causing at last advances backward stops.

Can also adopt structure as shown in Figure 3, non-return take turns 7 comprise in wheel 3 and foreign steamer 4, foreign steamer 4 is internally taken turns 3 motions mutually, interior wheel 3 is provided with non-return seat 5, foreign steamer 4 inner rings are provided with check sheet 6, and check sheet 6 is to be inclined to the obtuse angle form in the direction of the clock to arrange.Like this, check sheet 6 can not produce non-return effect with non-return seat 5 effects when advancing.If but want to retreat activity, then non-return seat 5 is relative with the direction of motion of check sheet 6, and check sheet 6 has been produced non-return effect, thus the speed that reduction pulley 2 retreats, directly causing at last advances backward stops.

Crank when the utility model adopts non-return 7 the mode of taking turns to use roller skate to retreat utilizes non-return principle to prevent that the beginner from driving in the wrong direction when sliding, and has improved the security of sliding effectively, and is convenient and practical.

Claims (1)

1. safe roller skate, the shoe rack bottom connects pulley, it is characterized in that the anterior pulley that connects of described shoe rack is non-return the wheel, described non-return the wheel comprises interior wheel and foreign steamer, foreign steamer is internally wheel motion mutually, wheel is provided with non-return seat in described, and the foreign steamer inner ring is provided with check sheet, and described check sheet is inclined to the obtuse angle form in the direction of the clock and arranges;

Or non-return the wheel be unidirectional tooth ratch, and the gear teeth are inclined to the acute angle form in the direction of the clock and arrange.
