Abstract

A pedal unit is composed of crank, bearing, supporting holder, and foldable pedal or integral pedal. Said bearing is connected between one end of crank and supporting holder. Said foldable pedal is connected to said supporting holder. When said pedal is folded, the notch on pedal is matched with said crank, so locking it.

Description

New-type pedal

The present invention relates to a kind of new-type pedal.

Bicycle, battery-driven car as a kind of light, quick, be fit to the vehicle of popular daily life, work, body-building recreation flexibly, vigorous demand is arranged on market.Pedal is as the parts of an indispensability, and its output, consumption also foot are surprising.The manufacturing of pedal in recent decades all is to have in mind on the pedal axle basically: a class is that installation shaft is forwarded moving or slided on axle and rotate on the pedal axle, and this class pedal rapid wear needs to change pedal, causes waste of material.Another kind of is to install some members additional to make pedal collapsible on first kind basis, and its maintenance is constant, fragile.In order better to make things convenient for the car owner, need a kind of life-span long, change less, interchangeability realizes that more by force, easily pedal can fold, again can a kind of new-type pedal of single-piece, satisfy car owner's different demands.

Purpose of the present invention just foot solves the existing deficiency of pedal, and a kind of new-type pedal is provided, and its a kind of stretcher can fold, and another kind of stretcher can be a single-piece.

The solution of the present invention is: new-type pedal comprises crank, bearing, bearing, Folding pedal plate; Whole stretcher; Crank one end links to each other with car body by axis, and the crank other end and bearing are by thread connection, and axle links with bearing in the bearing, and bearing links to each other with folded stretcher by screw; Or axle links with whole stretcher in the bearing, and it is characterized in that: described bearing is combined into 4 angular contact ball bearings successively by axle, ball, bearing inner ring, nut in outside race, the bearing, and bearing and crank link; Axle one end and bearing link by screw thread in the bearing, the Folding pedal plate passes through screw, the screw cover, spring washer links to each other with bearing, with six sides cover that the gap between screw and the Folding pedal plate is stifled real simultaneously, making screw and Folding pedal plate structure is one, the Folding pedal plate is axle with the screw, when folding, screw unclamps gradually on one side, screw is tightened gradually on one side, when Folding pedal plate one side breach and crank interlock, screw is twisted the most tightly on one side, produces the self-lock force of certain force under the effect of spring washer, makes the Folding pedal plate not have can not arbitrarily rotate under certain external force effect, move, when in like manner Folding pedal plate development and bearing intersect, self-lock force that another screw and spring washer form and bearing spacing makes the Folding pedal plate not have can not fold under certain external force effect, and this has just formed the collapsible of new-type pedal; Or axle links with whole stretcher in the bearing, forms the integral type of new-type pedal.

Adopt the beneficial effect of above scheme: bearing can be relatively independent with stretcher, bearing life is longer, be difficult for changing, bearing becomes the common portion of Folding pedal plate and whole stretcher, the car owner has two kinds of different selections, the manufacturing of stretcher is more convenient, and stretcher is also more durable, cuts the waste on the whole.

Also in conjunction with the accompanying drawings the present invention is done further detailed description below by concrete enforcement.

Embodiment one: as shown in Figure 1, this routine new-type pedal is made up of crank 1, bearing (be divided into axle 3 in outside race 2, the bearing, ball 12, bearing inner ring 4, nut 5, by constituting 4 angular contact ball bearings successively), bearing 6, screw 11, screw cover 8, Folding pedal plate 7.Crank 1 one ends link to each other with axis, and the other end is by its negative thread, link with the outside thread of outside race 2; Axle 3 links by screw thread and bearing 6 in the bearing, Folding pedal plate 7 is by screw 11, screw cover 8, spring washer links to each other with bearing 6, with 6 sides cover 10 that the gap between screw 11 and the Folding pedal plate 7 is stifled real then, make screw 11 and Folding pedal plate 7 constitute one, Folding pedal plate 7 is an axle with screw 11, when folding, screw unclamps gradually on one side, screw is tightened gradually on one side, when one side of Folding pedal plate 7 breach and crank 1 interlock, screw 11 is tightened on one side, forms certain self-lock force under the spring washer effect, and Folding pedal plate 7 can not arbitrarily be rotated under the effect that does not have certain force, move; During work, unfolded stretcher 7, when itself and bearing 6 intersected downwards, the self-lock force of another screw 11 and spring washer can not fold Folding pedal plate 7 under the effect that does not have external force, Here it is new-type pedal collapsible.

Embodiment two: shown in Fig. 2, this routine new-type pedal is linked by the outside thread of axle 3 and the negative thread of whole stretcher 9 in the bearing, forms the integral type of new-type pedal.

It is as follows to meet corresponding part name among each figure: 1, crank; 2, bearing outer ring; 3, axle in the bearing; 4, bearing inner race; 5, nut; 6, bearing; 7, folding pedal plate; 8, screw cover; 9, whole foot-operated Plate; 10, six square sets; 11, screw; 12, ball.

Claims

1, new-type pedal, comprise crank (1), bearing, bearing (6), Folding pedal plate (7), whole stretcher (9), crank (1) one end links to each other with main body by axis, crank (1) one end and bearing link, bearing links to each other with bearing (6) by axle (3) in the bearing, and bearing (6) links to each other with Folding pedal plate (7); Bearing links with whole stretcher (9) by axle (3) in the bearing; It is characterized in that: crank (1) links with bearing; Bearing and bearing (6) link, bearing (6) is by screw (11), screw cover (8), spring washer links to each other with Folding pedal plate (7), six sides covers (10) are blocked the gap between screw (11) and the Folding pedal plate (7), screw (11) forms one with Folding pedal (7), with screw (11) is axle, breach on Folding pedal plate (7) limit and crank (1) interlock, the self-lock force of screw (11) and spring washer generation simultaneously, Folding pedal plate (7) can not arbitrarily be rotated, move, when Folding pedal plate development and bearing (6) intersect, another screw (11) produces self-lock force with spring, bearing (6) is spacing in addition, Folding pedal plate (7) can not arbitrarily be folded, and this just realizes new-type foot-operated collapsible; Axle (3) links with whole stretcher (9) in the bearing, and this just realizes the integral type of new-type pedal.
