Abstract
The utility model discloses a pair of one-way-rolling skeelers. The utility model is characterized in that a one-way needle bearing is fixed in an axle hole of a rolling wheel, an axle penetrates through the one-way needle bearing, and a bearing or a circular steel sheet are respectively installed on two lateral axles of the one-way needle bearing. The advantages of a pair of skeelers using one-way rolling wheels lie in that a phenomenon that the skeelers roll backwards when the skeelers move can not be generated, and thus, the stability of movement and forward motive force are raised on the basis of an original structure.
Description
Technical field:
The utility model relates to the technical field of daily living article, specifically a kind of single roll roller skate.
Background technology: traditional roller skate can be divided into double rolling roller skate and single roller roller skate according to row's side of rolling, these two kinds of rolling roller skates mainly are to rely on both feet that the side force that it applies both sides is moved when motion, and main positive force can't play effect.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved roller skate, and it can utilize positive force to make it become the major impetus that produces motion.
To achieve these goals, the technical solution of the utility model is: a kind of single roll roller skate, it mainly comprises the footwear body, be contained in the axle and the roller at shoe bottom place, it is characterized in that: in the axis hole of roller, fix a unidirectional needle bearing, axle passes unidirectional needle bearing, respectively adorns a bearing or circular steel disc on two side shafts of unidirectional needle bearing.
Use the good effect of the roller skate of single roll roller to be can not produce the phenomenon of rolling backward, thereby on original basis, improved the stability of motion and the power that advances, and can utilize positive force to be used as producing the major impetus of motion.
Description of drawings:
Fig. 1 is the stereogram of the utility model one embodiment
Fig. 2 is the schematic diagram of roller among Fig. 1
Fig. 3 is the circular steel disc schematic diagram among Fig. 1
The specific embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises the footwear body, be contained in the axle and the roller 1 at shoe bottom place, it is characterized in that: in the axis hole of roller 1, fix a unidirectional needle bearing 2, axle 6 passes unidirectional needle bearing 2, respectively adorn a bearing or circular steel disc 3 on two side shafts of unidirectional needle bearing 2, the internal diameter of bearing or steel disc is identical with the diameter of axle.In circular steel disc, be provided with slot rolling, some steel balls 5 are housed in slot rolling, be provided with disk 4, in disk 4, be provided with the slot rolling that can hold steel ball in a side of circular steel disc.Be provided with screw thread on the surface of part axle in the enforcement, be provided with nut at the screw thread place of axle, the end of axle 6 is provided with axle cap; Axle 6 is diameter axles identical with the internal diameter of unidirectional needle bearing 2, unidirectional needle bearing 2 is enclosed within on the axle 6, axle 6 is by the axis hole of roller 1, the part that passes roller 1 at axle 6 is equipped with nut 7, nut 7 is fixed on roller 1 on the axle 6, and the roller skate that has is provided with support at the sole place, and this support is connected with axle, play the effect of fixed axis better, partly or entirely adopt unidirectional needle bearing in the roller of single roll roller skate.
Dynamic process of the present utility model is: when pin is stepped on roller skate backward, because axle is fixed with support and footwear, this moment, roller 1 had the trend of rolling backward, but because the characteristic of single-phase needle bearing 2 is to make one-directional rotation, be that forward can roll on axle and oppositely will twine extremely with axle, can make roller 1 and axle 6 keep static, thereby produce positive force, make that the roller on another pin travels forward; Otherwise scroll wheel can be made positive movement under effect of inertia.
Claims (3)
1, a kind of single roll roller skate, it mainly comprises the footwear body, is contained in the axle and the roller at shoe bottom place, it is characterized in that: fix a unidirectional needle bearing in the axis hole of roller, axle passes unidirectional needle bearing, respectively adorns a bearing or circular steel disc on two side shafts of unidirectional needle bearing.
2, by the described a kind of single roll roller skate of claim 1, it is characterized in that: in circular steel disc, be provided with slot rolling, some steel balls are housed in slot rolling, be provided with disk, in disk, be provided with the slot rolling that can hold steel ball in a side of circular steel disc.
3, by claim 1 or 2 described a kind of single roll roller skates, it is characterized in that: the surface at part axle is provided with screw thread, is provided with nut at the screw thread place of axle, and the end of axle is provided with axle cap.
