Abstract

The utility model relates to a particular durable bicycle pedal. The utility model has the advantages that the outer walls of the big end and the small end of a pedal shaft are respectively sheathed with a big and a small needle bearings; the outer walls of the two needle bearings are equally sheathed in corresponding sized bearing bowls; a sleeve barrel is abutted between the two bearing bowls; the outer walls of the big end mouth and the small end mouth of the pedal shaft are equally provided with screw threads; the outer end of the small needle bearing is locked by the screw threads on the outer wall of the small end of the pedal shaft, and corresponding pad sheets and screw caps; the two needle bearings and the outer ends of the bearing bowls are respectively provided with a baffle plate, and the two baffle plates are connected by corresponding supporting blocks and small locking screw rods, and are locked and fixed. Compared with similar products on the market, the cost of the utility model is increased about one thirds, and the service life can be prolonged more than eight times.

Description

Durable especially bicycle pedals

The utility model relates to bicycle pedals, a kind of especially durable especially bicycle pedals.

Existing bicycle pedals durability is bad, service life is not long.In mankind today to its living environment growing interest, limit gradually many countries and regions has the self-propelled vehicle of pollution to use to environment, makes people tend to use this environment-friendly type short range walking-replacing tool---bicycle more.If it is foot-operated that the bicycle user will frequently change, will bring many inconveniences to them, can produce the product design of bicycle unavoidably and query, so that the brand image of bicycle is caused some negative effects.

The purpose of this utility model is to design and a kind ofly increases cost about 1/3 on existing like product basis, and can prolong more than 8 times service life.

Technical solution of the present utility model is a kind of durable especially bicycle pedals, it is big by pedal spindle, put one on the outer wall at little two ends respectively greatly, little needle bearing, the outer wall of two needle bearings all is inserted in the cup of a corresponding size, withstand by a sleeve between the two bearings bowl, pedal spindle big, port, little two ends outer wall is equipped with screw thread, the outer end of little needle bearing is by screw thread on the small end outer wall of pedal spindle and the locking of corresponding pad nut, a baffle plate is respectively adorned in the outer end of two needle bearings and cup, and two baffle plates are by corresponding back-up block, the locking small screw connects and is locked.

The utility model further specifies as follows in conjunction with specific embodiments referring to accompanying drawing:

A kind of durable especially bicycle pedals, its structure are referring to accompanying drawing 1, and it is that the small end (14) of big needle bearing (4) from pedal spindle (3) put to stage casing (13), and allow it near big end of pedal spindle (3).In big needle bearing (4) outer wall cover National People's Congress's cup (6), in the end port of the portlet (20) of big cup (6) cover people's sleeve (9), be inserted in the portlet (21) of little cup (10) in the other end port of sleeve (9).Small end (14) to pedal spindle (3) puts little needle bearing (12) to little cup (10).Be the gradient design between the small end of pedal spindle, stage casing, the big end, move axially to the big end of pedal spindle to prevent two needle bearings.To the screw thread (16) of groove (15) and pad (18), the little needle bearing of two nuts (19) axial locking (12) and the axle bowl (10) thereof of corresponding inner wall belt salient angle (17), the transmission by sleeve (9) is big needle bearing of axial locking (4) and cup (6) thereof simultaneously by the tape spool of small end (14) port of pedal spindle.Putting a bottom centre from the big end of pedal spindle (3) has the Internal baffle (5) of annular distance (28) and annular groove (27) and allows the large port of big needle bearing bowl (6) and the annular groove (27) of Internal baffle (5) coincide.Put the outer baffle (11) that there are annular groove (30) in a bottom centre to small end (14) the port lock screw of pedal spindle (3), little needle bearing and cup thereof, and allow the annular groove (30) and the large port of little needle bearing bowl (10) coincide.Passed two holes (26) of two holes (29), two back-up blocks (7) centre holes (22), Internal baffle (5) of outer baffle (11) respectively with small screw (8) by two lockings after, each personal spring shim (24), nut (25) are tightened mutually with the screw thread (23) on the small screw (8).

Establish a symmetrical bayonet socket (2) on the big end outer wall of pedal spindle so as to install, dismounting, the big end port of pedal spindle is established screw thread (1) so that tighten mutually with the nut type screw thread of connecting rod one end that links with bicycle middle shaft.

Pedal spindle of the present utility model (3) has another kind of structure as shown in Figure 7, the big end of pedal spindle with in the intersegmental block card (31) of establishing to prevent that from the big end of pedal spindle needle bearing moves to the stage casing of pedal spindle on axle during the big needle bearing of suit.

The utility model has the advantage of: the basis at existing like product increases cost about 1/3, And can prolong more than 8 times service life.
