Abstract

An adjustable pedal comprises a working beam, a pedal body, a connecting lug, a fixing shaft, a gasket, a cotter pin, an adjusting screw and a spring. A stop piece is arranged under the tail end of the working beam. A screw through hole is formed in the stop piece. The adjusting screw penetrates the spring to be screwed in the screw through hole in the stop piece. The stop piece is arranged under the working beam and the adjusting screw is arranged on the stop piece, so that an operator can adjust angles of the pedal in the stationary state as required, the angle between the pedal and the working beam can be automatically adjusted, stability of a contact surface between the sole and the pedal can be sustained, and requirements on experience and ability of the operation can be reduced.

Description

A kind of adjustable foot pedal

Technical field

The present invention relates to the field that a kind of automobile, machinery etc. need to use stretcher, belong to stretcher optimization technique.

Background technology

The stretcher using at present, as braking automobile, clutch foot plate, most stretcher is all to adopt directly fixing mode with being connected of working beam, namely the angle between stretcher and working beam can not change.The particularly stretcher of suspension type, when work, along with the variation of pedal position, the angle of stretcher and operator's sole is also in continuous variation, if operator's sole is not adjusted angle, and the area of contact between stretcher will be fewer and feweri, very easily producing slides there is danger.If want to keep contact surface stable of stretcher and sole, just must the random contact angle of adjusting sole and stretcher with Adaptive change.And in fact, due to the characteristic of this suspension type structure, and the characteristic of Human Physiology structure, above-mentioned requirements cannot be accomplished.

A kind of self adaptation stretcher is disclosed in the patent document that is 201020193301.8 in my patent No., working beam is connected by U-shaped seat with stretcher, can automatically adjust the angle between stretcher and working beam, between maintenance sole and stretcher, contact surface is stable, deficiency is that U-shaped seat is fixed on pedal and is had difficulties, conventionally adopt the mode of welding, but U-shaped middle gap is less, welding difficulty.

Therefore, need to find a kind of novel stretcher, not only can automatically adjust the angle between stretcher and working beam, make contact surface between sole and stretcher keep stable, and structure more simply, easily realize.

Summary of the invention

The object of this invention is to provide a kind of adjustable foot pedal, can automatically make the contact surface between operator's sole and stretcher keep stable, reduce the requirement to operator's experience and ability.

Technical scheme of the present invention is: a kind of adjustable foot pedal, formed by working beam 1, stretcher 2, lug 3, anchor shaft 4, packing ring 5, spring cotter 6, governing screw 7, spring 8, stop block 11 is set below working beam 1, and governing screw 7 is set on stop block 11, make operator can adjust as required the angle of stretcher 2 in quiescence.

The end below of described working beam 1 is provided with a stop block 11; On described stop block 11, be provided with a screw through-hole, governing screw 7, through spring 8, is screwed in the screw through-hole on stop block 11; Described anchor shaft 4 is through the mounting hole on lug 3 and the mounting hole on working beam 1, then through packing ring 5, spring cotter 6 is inserted in the jack on anchor shaft 4, and working beam 1 and lug 3 are linked together.

The top of working beam 1 end is quadrntnt type, is provided with a mounting hole at home position, and described mounting hole center is less than mounting hole center on lug 3 distance to stretcher 2 to the distance of the terminal edge of working beam 1; Make stretcher according to mode of operation, automatically adjust the angle between stretcher and working beam, between maintenance sole and stretcher, contact surface is stable.

In the time of quiescence, the stop block 11 of working beam 1 props up stretcher 2, makes stretcher keep stable.

In operating process, while stepping on stretcher 2, working beam 1 can be subjected to displacement, stretcher 2 and lug 3 will rotate as axle center take anchor shaft 4, automatically adjust the angle between stretcher 2 and working beam 1, make the contact surface between sole and stretcher 2 keep maximum, can not produce slip, reduce the requirement to operator's experience and ability.

The invention has the beneficial effects as follows:

1, make stretcher according to mode of operation, automatically adjust the angle between stretcher and working beam, between maintenance sole and stretcher, contact surface is stable, reduces the requirement to operator's experience and ability;

2, stop block is set below working beam, and governing screw is set on stop block, make operator can adjust as required the angle of stretcher in quiescence.

Below in conjunction with drawings and Examples, the present invention is further described.

Fig. 2 is three-dimensional exploded view of the present invention;

Fig. 3 is static schematic diagram of the present invention;

Fig. 4 is dynamic schematic diagram of the present invention.

In figure 1, working beam, 11, stop block, 2, stretcher, 3, lug, 4, anchor shaft, 5, packing ring, 6, spring cotter, governing screw 7, spring 8.

The specific embodiment

As depicted in figs. 1 and 2, a kind of adjustable foot pedal, is made up of working beam 1, stretcher 2, lug 3, anchor shaft 4, packing ring 5, spring cotter 6, governing screw 7, spring 8, and the end below of described working beam 1 is provided with a stop block 11; On described stop block 11, be provided with a screw through-hole, governing screw 7, through spring 8, is screwed in the screw through-hole on stop block 11.Operator can, according to the requirement of self, by governing screw 7, adjust stretcher angle under static state, until be applicable to oneself operation.

Described lug 3 one end are fixed on stretcher 2, and it is semi-circular that the other end is, and are provided with a mounting hole at the home position of semi-circular one end of lug 3.The top of working beam 1 end is quadrntnt type, is provided with a mounting hole at home position, and described mounting hole center is less than mounting hole center on lug 3 distance to stretcher 2 to the distance of the terminal edge of working beam 1.

Described anchor shaft 4 is through the mounting hole on lug 3 and the mounting hole on working beam 1, then through packing ring 5, spring cotter 6 is inserted in the jack on anchor shaft 4, and working beam 1 and lug 3 are linked together.

As shown in Figure 3, in the time of quiescence, the stop block 11 of working beam 1 props up stretcher 2, makes stretcher keep stable.As shown in Figure 4, in operating process, while stepping on stretcher 2, working beam 1 can be subjected to displacement, and because stretcher 2 is fixedly connected with lug 3, stretcher 2 and lug 3 will rotate as axle center take anchor shaft 4, thereby automatically adjust the angle between stretcher 2 and working beam 1, make the contact surface between sole and stretcher 2 keep maximum, can not produce slip, reduce the requirement to operator's experience and ability.

Above-described embodiment is only for interpretation purposes of the present invention, and is not limitation of the present invention, and those skilled in the art, in essential scope of the present invention, make a variety of changes or substitute, and also should belong to protection category of the present invention.
