Abstract

The utility model relates to a coupling device for a bicycle stand. The utility model is composed of a bracket, a handle, a driving member, and a pressing block, wherein, the bracket is arranged at the position where a vertical pipe and a vertical fork are crossed and connected, and the handle is connected with the bracket. The utility model is characterized in that the handle operates the driving member which drives the pressing block, and the pressing block is detachably connected with the radial end surface of a front beam which passes through the bracket. The utility model has the advantages that the center distance between a front pipe and a vertical tube which are connected to the front end of the front beam is adjustable; the utility model is suitable for riders in different stature; the occupation area of the utility model can be reduced.

Description

The cycle frame connecting device

The utility model relates to the main component of the land of rider driving with wheeled car.Specifically, the utility model is a kind of mechanical device that relates to the bicycle skeleton, a kind of cycle frame connecting device of absolving use.

At present the front-axle beam of cycle frame and standpipe, upright pitch to connect what generally adopt be the version of fixing, pipe is the typing unmodified with the middle receipts distance of standpipe before it, this how appropriate for different stature riders is relatively limited to, and for depositing, carries also inconvenience that have more.

The purpose of this utility model is a limitation and inconvenience of avoiding existing bicycle frame structure form to reflect, a kind of novel cycle frame connecting device that connects between front-axle beam and standpipe, the upright fork that constitutes is provided, and pipe was regulated change with the width between centers of standpipe before it can make.

The purpose of this utility model can be achieved by following technical proposals: intersect point of attachment at standpipe and upright fork, if with axial two ends is the support that straight line connects, with the handle that is connected in support, driving member and briquetting, handle, driving member, briquetting connect and transmission in proper order, briquetting with the perpendicular radial orientation of support axis on form displacement, passing the axial of this support is the two-tube front-axle beam of straight line parallel, its front end connects with preceding pipe, the rear end is that involution connects silently, and its radial end face contacts with this support and constitutes connecting of can absolving with briquetting.

Driving member described in the utility model can be the disk cam member, is connected in proper order and transmission by handle, cam, camshaft guide rod, briquetting.Also can be spiral component, be connected in proper order and transmission by handle, bolt, nut guide rod, briquetting, can also be the ramp member of other suitable forms.

Saddle places the top of described support, and the saddle member can be connected in support, also can be connected in standpipe, can also be to be connected in upright fork.

Compared with prior art the utility model has the advantages that: the preceding pipe of vehicle frame and the adjustable center distance of standpipe joint change, and can adapt to the rider of different statures, can reduce floor area again.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is first embodiment cross section structure scheme drawing of the present utility model.

Fig. 2 is second embodiment cross section structure scheme drawing of the present utility model.

Among the figure: 1, support 2, standpipe 3, upright fork 4, saddle pipe 5, front-axle beam

6, pivoted housing 7, briquetting 8, briquetting mandrel 9, setting nut

10, spring 11, handle 12, cam 13, camshaft guide rod

14, hasp 15, bolt 16, nut guide rod

Among Fig. 1, Fig. 2 embodiment, axially two ends are that the support 1 that straight line connects vertically is arranged at standpipe 2 upright fork 3 crossing connecting portions, saddle pipe 4 members of top are connected in support 1, front end front connecting tube rear end is established involution and is connected the two-tube front-axle beam 5 of axial straight line parallel silently through support 1, it is the pivoted housing 6 of dead axle with the thru-bolt that front portion that support 1 is axial and rear portion all are provided with one group, with briquetting 7, the briquetting mandrel 8 that laterally runs through support 1 mandrel hole, the one end is provided with setting nut 9, the centre is provided with spring 10, and its other end connects with driving member.

In embodiment illustrated in fig. 1, driving member of the present utility model is the cam 12 that is configured to camshaft guide rod 13, camshaft guide rod 13 axial two ends connect with briquetting mandrel 8 respectively, handle 11 operation of cam 12, be transmitted in briquetting 7, briquetting 7 is at the radial orientation top offset of support 1, constitute with front-axle beam 5 absolve connect, handle 11 is located with the hasp 14 of activity operations.

In embodiment illustrated in fig. 2, driving member of the present utility model is the bolt 15 that is configured to nut guide rod 16, nut guide rod 16 axial two ends connect respectively with at briquetting mandrel 8, handle 11 operating screws 15, be transmitted in briquetting 7, briquetting 7 is at the radial orientation top offset of support 1, constitute with front-axle beam 5 absolve connect.

In the foregoing description, contact with the front-axle beam 5 radial end faces position that connects of support 1, pivoted housing 6, briquetting 7 also can be set up to alleviate the gasket material with the friction of front-axle beam 5 finish coats.

Certainly, application setting of the present utility model can also be other suitable versions.

Claims
