Abstract
The utility model relates to a new structure of a middle axle of a bicycle pedal, which is fastened by the screw threads between an outer sleeve barrel and a locating sleeve. A middle axle is fixedly locked in the outer sleeve barrel and the locating sleeve, and balls are positioned in a ball seat and a ball groove. The middle axle can be clamped into a jogged groove between the outer sleeve barrel and the locating sleeve by a clamping tenon of an inserting and fixing ring. Thereby, the middle axle of a pedal can not loosen in the shake and rotation of a long time. The utility model has the effects of safe fastening and convenient assemble.
Description
The utility model is the improvement of axle construction in a kind of bicycle pedal.
Used bicycle pedal axis (shown in figure one) is locked in ball 5A between axis 1A and the outer sleeve 2A by inner sleeve 4A, utilizes jam nut 3 with its packing locking again.The shortcoming that this kind structure exists is to be screwed between jam nut and the screw thread in the shake rotation over a long time to become flexible gradually; And when the adjusting play, need utilize two instruments to carry out interlocking,, make adjusting work feel more difficulty owing to limited by space-constrained; As be docked in new product, then very uneconomical.
The utility model is exactly that shortcoming at above-mentioned existence proposes a kind of bicycle pedal axis new construction, and the pedal axis is fastened securely, and anti-loosing effect is good, and easy to operate.
The purpose of this utility model is to realize institute like this.A kind of bicycle pedal axis new construction by axis, outer sleeve, locating bush, and the build-in ring constitute, it is characterized in that being provided with two ball-bearing housings at the axis two ends; Outer sleeve is a ducted body, is sheathed on the axis by left end, and one end end endoporus is provided with ball grooves, and its middle part is provided with negative thread and other end peritreme is provided with at least eight five equilibrium emboss pits, has the long embeded slot of a pair of symmetric arrangement in this groove at least; Locating bush also is a ducted body, and is provided with the outside thread that the negative thread with outer sleeve is screwed in its terminal periphery, and its front end cylindrical is provided with and the corresponding concavo-convex groove of the emboss pit of outer sleeve, and its front top is a hexagon nut; Build-in is equipped with at least two five equilibriums and symmetrical trip, sees from the side, is the JiongZi Xing shape; When outer sleeve negative thread and locating bush external thread spiro fastening, ball is positioned in two pairs of ball bases, the groove, and the trip of Jiong type build-in ring snaps in outer sleeve and the locating bush embeded slot at certain position, combine closely with formation, make it unlikely loosening in shake rotation over a long time.
Below again with accompanying drawing to embodiment further as with explanation.
Description of drawings:
The bicycle pedal axis constructional drawing that Fig. 1 is traditional.
Fig. 2 three-dimensional system diagram of the present utility model.
Fig. 3 three-dimensional assembly diagram of the present utility model.
Fig. 4 cutaway view of the present utility model.
As shown in Figure 2, axis 1 two ends are provided with two ball bases 11, be inserted in an outer sleeve 2 that is ducted body by left end, bore edges is established ball grooves 21 in the tail end of outer sleeve 2, the middle part is provided with negative thread 22, the front aperture periphery is established the emboss pit 23 that is no less than eight five equilibriums, and the long embeded slot 24 of the symmetric arrangement that is no less than two is wherein arranged; Locating bush 3 also is ducted body, is inserted in by axis 1 right-hand member, and bore edges is provided with ball grooves 31 in the locating bush 3, and the tail end periphery is provided with outside thread 32, and the front end periphery also is provided with the embeded slot 33 of many eight five equilibriums, and the top is a hexagon nut 34; Build-in ring 4 is the hollow JiongZi Xing, and the trip 41 that is no less than 2 symmetric arrangement is arranged.Shown in Fig. 3,4, when outer sleeve 2 and locating bush 3 both screw threads screw togather, axis 1 is locked in it, ball 5 also is positioned between ball base 11 and the ball grooves 21,31, again the trip of build-in ring 4 is snapped among the embeded slot 24,33, can reach the locking effect that is fastened securely.
In sum, structure of the present utility model truly has simple and convenient assembly, the locking effect of safety, and assembly all can be made into integration, and need not unnecessaryly process, and is suitable for stock production, thereby saves man-hour and manufacturing cost, has good and economic.
