Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the ladder in the bicycle of length that can regulate that the utility model provides is described in detail.
As shown in Fig. 1-Fig. 4, what the utility model provided can regulate a ladder in the bicycle of length to comprise 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 medial surface 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 inner circumference face, 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 front 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 corrugated in the middle part of the both sides of the edge of described strip shape lock hole 6.
The middle part of described supporting leg 1 is formed with bending part outstanding forward.
The terraced using method in the bicycle of length that can regulate now provided by the utility model 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.
