Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide in a kind of bicycle of adjustable-length props up ladder.
In order to achieve the above object, in the bicycle of adjustable-length that provides of the utility model, a ladder comprises supporting leg, hoof pin, button, spring; Wherein the upper end thereof of supporting leg is on the permanent seat be connected between axis and trailing wheel and with vehicle frame, its underpart is hollow tubular structure and outer circumference face is formed with vertically a strip shape lock hole, and the both sides of the edge of strip shape lock hole are corrugated; The upper end of hoof pin is enclosed within outside, supporting leg bottom, on its upper outside periphery, being outwardly formed with an annular button arranges seat, and the both sides circle wall that button arranges seat is formed with an elongated hole arranged along its length respectively, hoof pin is positioned at the position that button arranges base rear end simultaneously and is formed with a through hole; Button is the nail shape structure be made up of discoid button head and button spindle, and the mode outside being positioned at button head is arranged on button and arranges seat, and wherein the both sides of button head are respectively equipped with an outside bending and are positioned at the hook that button arranges elongated hole on seat; Button spindle is made up of with the outer end be positioned at outside root the root near button head, and wherein root is flat rod, and outer end is discoid; Spring housing is outside at root, and button spindle can through the through hole on hoof pin and the strip shape lock hole on supporting leg.
On described strip shape lock hole, two relative peak-to-peak distances of ripple are greater than the width of root on button spindle and are less than the diameter of outer end.
Distance on described strip shape lock hole between two relative troughs is greater than the diameter of outer end on button spindle.
In the bicycle of the adjustable-length that the utility model provides, a ladder can utilize and regulate the method for relative position between its upper supporting leg and hoof pin to regulate its total length, therefore can support the use with the vehicle frame of different size, so significantly can reduce investment, and reduce productive costs.In addition, in this bicycle, ladder also has reasonable in design, the advantage such as easy to use, both artistic and practical.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, a ladder in the bicycle of the adjustable-length that the utility model provides is described in detail.
As shown in Fig. 1-Fig. 3, in the bicycle of the adjustable-length that the utility model provides, a ladder comprises supporting leg 1, hoof pin 2, button 3, spring 4; Wherein the upper end thereof of supporting leg 1 is on the permanent seat 5 be connected between axis and trailing wheel and with vehicle frame, its underpart is hollow tubular structure and outer circumference face is formed with vertically a strip shape lock hole 6, and the both sides of the edge of strip shape lock hole 6 are corrugated; The upper end of hoof pin 2 is enclosed within outside, supporting leg 1 bottom, on its upper outside periphery, being outwardly formed with an annular button arranges seat 7, and the both sides circle wall that button arranges seat 7 is formed with an elongated hole arranged along its length 8 respectively, hoof pin 2 is positioned at the position that button arranges seat 7 rear end simultaneously and is formed with a through hole 9; Button 3 is the nail shape structure be made up of discoid button head 10 and button spindle 11, mode outside being positioned at button head 10 is arranged on button and arranges seat 7, and wherein the both sides of button head 10 are respectively equipped with an outside bending and are positioned at the hook 12 that button arranges elongated hole 8 on seat 7; Button spindle 11 is made up of with the outer end 14 be positioned at outside root 13 root 13 near button head 10, and wherein root 13 is flat rod, and outer end 14 is discoid; It is outside that spring 4 is enclosed within root 13, and button spindle 11 can through the through hole 9 on hoof pin 2 and the strip shape lock hole 6 on supporting leg 1.
On described strip shape lock hole 6, two relative peak-to-peak distances of ripple are greater than the width of root 13 on button spindle 11 and are less than the diameter of outer end 14.
Distance on described strip shape lock hole 6 between two relative troughs is greater than the diameter of outer end 14 on button spindle 11.
In the bicycle of the adjustable-length now provided by the utility model, a terraced using method is described below: when needs regulate length, first inwardly 3 are pressed the button by user with hand, the outer end 14 of button spindle 11 on it and root 13 outside left is made to be entered into the inside of supporting leg 1 successively by space between the opposed valleys of strip shape lock hole 6 on through hole 9 on hoof pin 2 and supporting leg 1, Compress Spring 4 simultaneously, because the width of root 13 on button spindle 11 to be less than on strip shape lock hole 6 two relative peak-to-peak distances of ripple, therefore hoof pin 2 can be moved up and down in this case, until be adjusted to required length, release button 3 afterwards, at this moment on button spindle 11, to arrange seat 7 inner by being retracted to button under the resilient force of spring 4 successively by the through hole 9 on space between the opposed valleys of strip shape lock hole 6 on supporting leg 1 and hoof pin 2 root outside left and outer end 14, thus utilize spring 4 to be fixed the position between supporting leg 1 and hoof pin 2.Because button head 10 both sides are provided with hook 12, and hook 12 is positioned at button and arranges elongated hole 8 on seat 7, and therefore in use button 3 can not arrange in seat 7 from button by the constraint of elongated hole 8.
