Abstract
The utility model relates to enclosed cycle pedals, comprising a pedal axis, an axis bowl, a steel ball, a plate and a screw bolt. The utility model is characterized in that a similar ball bearing structure is formed by the pedal axis, the axis bowl and the steel ball. The enclosed cycle pedals are clipped in the upper and lower plates and fixed by bolts and the utility model has the advantages of less components, compact structure, good closeness, long service life, etc.
Description
The utility model relates to a kind of closed bicycle pedal, is parts of bicycle.
Existing bicycle pedal, by pedal axle, axle bumper, axle internal key card, axle cap, axle bowl, interior catch, outer catch, central siphon, string skin rod, step on skin, steel ball etc. and form, its weak point is that not only constituent elements is many, cost is high, set-up cost man-hour, the maintenance trouble, and leak tightness is poor, and the silt and the water capacity easily enter in the axle bowl, corrosion and wearing and tearing steel ball, axle bowl, easy break-down, service life is short.
The purpose of this utility model is to provide a kind of compact conformation, constituent elements few, and cost is low, installs and uses closed bicycle pedal easy to maintenance.
The purpose of this utility model reaches by following technical measures: leave twice are recessed into arc surface along its circumference ball conduit on the face of cylinder of pedal axle, axle bowl of each suit on the ball conduit, steel ball is contained in the structure that forms similar bearing between ball conduit and the axle bowl, step tread is formed by two clamping plates butt joint up and down, last, the face of joint place of lower plate has the recessed mother of axle of the semi-cylindrical that the pedal axle is installed and the recessed mother of axle bowl of dress axle bowl respectively, pedal axle and axle bowl are installed between the lower plate, in the axle bowl 2 recessed mothers of axle bowl that are inlaid on the lower plate, the pedal axle places in the axis hole that is synthesized by the recessed mother of semicylinder oblique crank Z on the last lower plate, and last lower plate connects with bolt.
The utility model only is made up of several parts such as pedal axle, axle bowl, ball, last lower plate and bolts, and pedal axle, axle bowl and steel ball are installed in encapsulation between the lower plate, so it is few that the utility model not only has a constituent elements, compact conformation, cost is low, assemble simple advantage and because good airproof performance, ball, axle bowl etc. is avoided the infringement of silt and water, and is not easy to wear.In addition, the stressing conditions of rotatable parts such as ball is identical with ball bearing of main shaft, and strained condition is reasonable, rotates freely, and is not fragile, long service life, and installation and maintenance are all very easy.
Following accompanying drawing has been described embodiment of the present utility model.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is monnolithic case figure of the present utility model.
1 is the pedal axle among the figure, on the face of cylinder of pedal axle 1, process twice and be recessed into the ball conduit 4 of arc surface along its circumference, and axle bowl 2 of each suit on ball conduit 4, axle bowl 2 can form with the iron plate punching stretch forming or with the machinework of pachydermia iron pipe.Between ball conduit 4 and the axle bowl 12 steel balls 3 are housed, make it to become similar ball bearing structure, step tread 12 is by train wheel bridge 5 and lower plate 6 butt joints and with bolt 9 fastening forming, and last lower plate is with solid rubber or rubber-plastics material is hot-forming makes.When hot-forming, at the interface place of last lower plate in order to semicylinder oblique crank Z recessed female 7 that pedal axle 1 is installed and recessed female 8, also one-shot forming simultaneously in order to the axle bowl of installation shaft bowl 2.Pedal axle 1 and axle bowl 2 are installed between the lower plate, and its assembly method is: spread glycerine in axle bowl 2.The steel ball arrangement is bonded on the axle bowl inwall ball orbit, again it is sleeved on the ball conduit 4 of pedal axle 1, the rim of a bowl of two axle bowls is installed relatively.Then above-mentioned two axle bowls are inlaid in the axle bowl recessed female 8 of lower plate 6, pedal axle 1 places them in recessed female 7,, with bolt 9 last lower plate is fixedly connected into bicycle pedal with train wheel bridge 5 make-ups in the above again, and 10 is bolt hole among the figure.For further improving the seal degree of pedal.In the present embodiment, added a circle sand prevention projection 13 near pedal axle outer end, sand prevention groove 14 is arranged on last lower plate correspondingly, convex-concave is combined in the gap that forms bending between axle and clamping plate and better stops silt, and protection axle bowl plays sealing function.
