Description

Prop stand of bicycle

The utility model is a kind of Prop stand of bicycle, belongs to a kind of vehicle braked and bearing set.

The braking of bicycle at present is two cover independent device with supporting, and desire stops bicycle and makes it keep stabilized conditions, and the user at first must brake, after getting off the car support is propped up on ground.This operating process need be passed through several steps, and is comparatively loaded down with trivial details, and when running into emergency situation and need stop, may cause the accident because of there isn't enough time.

The purpose of this utility model is: design a kind of Prop stand of bicycle, it can be fallen support in a control by hand, make bicycle in stabilized conditions, and needn't get off.

The utility model comprises a support, there is an axis to be fixed on the below of support, sleeve that axis is outer and crossbeam hinge joint, this crossbeam one end embeds the below of support, the other end is connected to a control line, and the other end of control line has a rim brake, the bottom of sleeve have one with its radially angled slotted hole, the support that is embedded sleeve by the below is supported the pin that is connected and is linked to each other with sleeve by passing this Kong Bingyu, and support is bending.In use, support of the present utility model is fixed on the back lower place of cycle frame, pinching rim brake under motoring condition, the control line upward movement that then is attached thereto, further driving crossbeam is support motion with the support.Because the middle part of crossbeam and sleeve hinge joint, so sleeve is simultaneously along the axis upward movement.The slotted hole of lower cartridge be fixed under the mutual action of the pin in the support, the support of bending is rotated, and its underpart is promoted or falls, thereby makes bicycle be in motion or stabilized conditions.When the mode of operation of conversion bicycle, sleeve need be set back, therefore designed an inner protuberant ring in the sleeve of the present utility model, a projection is also arranged on the axis surface, a spring is arranged between inner protuberant ring and projection.Said projection can be a pin that is fixed on the axis.Support of the present utility model preferably includes support link and supporter, and both at angle; The top of support link is arranged in sleeve, and lower end and its hinge joint of support link passed in the upper end of supporter, between this end of supporter and the support link spring arranged, and has on the another side of support link and the cooresponding fan groove in supporter position.When snowing or rainy day, the road surface was more sliding, be difficult for falling down for making bicycle keep stable in the process of moving, support of the present utility model can be fallen, and when Uneven road, because the effect of spring, the support meeting has a rotation in the scope of fan groove, thereby can not influence the normal operation of bicycle.Rim brake of the present utility model comprises a shell, the quadrntnt that has the handle of a disk and be positioned at the one side respectively by its circle centre position hinge joint in the inside of shell, and handle is exposed to the outside of shell; One spring and a line segment are arranged in the shell, and they have an end to be fixed on the quadrntnt respectively, and the other end and the shell of spring are connected, and the other end of line segment passes shell, and a moment is arranged between line segment and the spring.Rim brake is fixed in the bicycle handle bar, line segment is exposed to the outer end of shell links to each other with the brake handle of bicycle, and this structure can make the utility model control the lifting and the whereabouts of support respectively by handle and brake.Said control line is divided into two-way in the middle, each road control line drive respectively one group by support, crossbeam, axis, sleeve, and support the structure of forming.In use, with these two groups of both sides that are installed in bicycle rear respectively, guarantee its stability under halted state.

Below in conjunction with accompanying drawing the utility model is elaborated.
