Abstract

The utility model relates to a gap device of foot pedals for a bicycle. The head end of a vertical post core on a column torsion spring is clamped in a flat groove of a convex post of a tail wing plate, and the tail end is clamped in a side groove of a tail end sleeve tube on a foot pedal main body. A wear-resistant bushing is sheathed on a tail end sleeve end tube, and a flange of the bushing is pressed between the tail wing plate and the tail end sleeve tube. The utility model avoids the problems that an angle needs prepressing and both ends of the torsion spring penetrate through small holes at both ends when both ends of the existing torsion spring and a shaft center are arranged in a parallel linear mode. The utility model overcomes the defects that the assembly is complicated, components are numerous and especially the torsion spring is easy to spring and fall off.

Description

The inter space device of bicycle pedal

A kind of inter space device of bicycle pedal, it relates to the running clearance pedal of bicycle pedal.

The topmost key of bicycle of match usefulness is how to improve power resources, and key was that its foot and pedal contact stabilization just can be won the victory when just the entrant rode.Therefore, they all are willing to select for use and have a skidproof buckle-type pedal.This pedal is at the crank shaft core tail end cylindricality torsion spring assembly to be housed, it can make the pedal main body that steering gap is arranged, and make the rider feel comfortable, but this pedal structure is, hold 131 by the termination of cylindricality torsion spring 13 is parallel with the center always, be inserted in adapter sleeve on the pedal main body 1 tail end sleeve pipe 10 in the aperture 121 at 12 the end, adapter sleeve utilizes two ears, 122 decks in short slot 101, axle bush 11 of cover on the cylindrical, cylindricality torsion spring another and center, parallel straight end 132 is inserted in the interior dark hole 141 of empennage clothing 14, the structure shown in attached Fig. 1 and 2, its assembly is many, assembling is complicated, particularly torsion spring two holes of inserting are on a line of centers, and are provided with and give the pressure angle, cause except that being difficult for the mating holes position, the defective that bullet takes off also easily takes place, and causes the weak point that expends man-hour.

The purpose of this utility model is the inter space device that discloses a kind of bicycle pedal, and it is with the cylindricality torsion spring of pedal, and does not make and the line of centers vertical configuration Ka termination, and tail end is stuck in the tail plate side channel, and head end is stuck in the pedal main body tail end sleeve pipe side side-groove hole.The defective that reduces assembly parts and make assembling become and avoid the torsion spring bullet to take off easily.

The utility model is realized by following measure, the head end that the cylinder torsion spring is vertical with axial line is not stuck in the flat groove of the middle projection of tail plate, torsion spring and central vertical tail end, be not stuck on the side channel on the pedal main body tail end sleeve pipe, tail end cover external diameter of pipe upper sleeve through has a wear-resisting axle bush, and the flange of axle bush is crushed between the flange and tail end sleeve pipe of tail plate.

The utlity model has advantage is:

1, simple and convenient assembly, easily needs when having avoided assembling torsion spring given and turns round an angle insert embedding, time-consuming operation, and the defective that can not cause the torsion spring bullet to take off again in adapter sleeve bottom face aperture.

2, save the adapter sleeve part, reduced productive costs, improved production efficiency.

Accompanying drawing 1, existing bicycle pedal running clearance device axonometric exploded view

Accompanying drawing 2, existing bicycle pedal running clearance device cutaway view

Accompanying drawing 3, the utility model axonometric exploded view

Accompanying drawing 4, the utility model assembling view

In conjunction with the accompanying drawings the inter space device of the utility model bicycle pedal is described further below by embodiment:

In accompanying drawing 3, be shaped on a side channel 2101 for the treatment of card people cylinder torsion spring on the tail end 210 of pedal crank shaft core 20; The bottom has the wear-resisting axle bush 24 of flange 241; Cylinder torsion spring 22 is made cylindric, the not card end 221 at torsion spring two; 222 are bent into respectively and the axial line vertical direction; There is cylindricality ladder projection 231 in the centre of tail plate 23, has flat groove 2310 and the flange that is inserted in main shaft 20 tail ends 210 on the top.

In accompanying drawing 4, cylinder torsion spring 22 is set on the cylindricality ladder projection 231 of tail plate 23 front ends, its head end and axial line vertical component are stuck in the tail ends vertical with axial line in the flat groove 2310 on the projection 231, are not stuck in the side channel 2101 on main shaft 20 tail ends 210.Tail end sleeve pipe 210 external diameter upper sleeve throughs have a wear-resisting axle bush 24, and the flange 241 of axle bush is crushed on and constitutes the bicycle pedal inter space device between tail plate 23 and the tail end sleeve pipe 210.

Claims

A kind of inter space device of bicycle pedal, it is made up of tail plate, torsion spring, anti-wearing liner, it is characterized in that: the head end (222) that cylinder torsion spring (22) is vertical with axial line is not stuck in the flat groove (2310) of the middle projection of tail plate (23) (231), the tail end that torsion spring is vertical with line of centers is not stuck on the side channel (2101) on pedal main body (21) the tail end sleeve pipe (210), and tail end sleeve pipe (210) external diameter upper sleeve through has its flange of a wear-resisting axle bush (24) (241) to be crushed between the flange and tail end sleeve pipe (210) of tail plate.
