The folder folds rapidly, has stable distance between two wheels and is convenient for pushing.

Description

A kind of folder

Technical field

The present invention relates to bicycle, Electrical Bicycle parts, particularly relate to a kind of folder.

Background technology

Bicycle, Electrical Bicycle are the desirable walking-replacing tools of people, and reality is used very universal.Folding bicycle, it is little, easy to carry to take up room after Electrical Bicycle is folding.Be placed on family after having the family of elevator to fold, play theft-proof effect, consider also can save the expense of parking from the angle of economy, charging is also convenient.

Bicycle, the common folder of Electrical Bicycle generally need be bent over, and the deals hand rotates fastener, fold after opening action such as insurance, and be very loaded down with trivial details;

Bicycle, the distance after Electrical Bicycle is folding between two-wheeled generally can not be fixed, and causes to carry out difficulty, advances after can only be portable, and user satisfaction is not high.

Summary of the invention

Technical matters to be solved by this invention is exactly to provide a kind of convenient, fast, stable folder for the defective that overcomes above-mentioned prior art existence.

Purpose of the present invention can be achieved through the following technical solutions: a kind of folder, it is characterized in that, comprise inner core, shell, described inner core comprises inner casing, two locating pin structures, two springs and a connection lead, described inner casing articulates by a bearing pin and shell, this inner casing is provided with first through wires hole and two spring registration arms that are parallel to each other, described two locating pin structures are arranged at the axial both sides of spring registration arm, these two locating pin structures include fixed plate, left side locating dowel pin and right locating dowel pin, described fixed plate is provided with through wires hole, described left locating dowel pin and right locating dowel pin are fixed in the two ends, the left and right sides in fixed plate front, described two springs are arranged in respectively in two spring registration arms, touch mutually with the two ends, the back side of two locating pin structure fixed plates respectively at the two ends of these two springs, described connection lead one end is fixed on the fixed plate, the other end passes the through wires hole of two fixed plates successively and the brake handle of first through wires hole and bicycle is fixed, and the both sides up and down of described shell are provided with first knock hole group and the second knock hole group suitable with locating dowel pin.

The both sides up and down of described shell also are provided with the 3rd knock hole group, when inner core launches the 3rd knock hole group and two right locating dowel pins suitable.

Angle α between described the 3rd knock hole group and the first knock hole group and the second knock hole group is 130 °～150 °.

Described angle α is 141 °.

Compared with prior art, the present invention is folding quick, the two-wheeled stable distance, and it is convenient to carry out.

Description of drawings

Fig. 1 is the structural representation of closure state of the present invention;

Fig. 2 is the structural representation of deployed condition of the present invention;

Fig. 3 is the plan structure scheme drawing of Fig. 2.

The specific embodiment

The invention will be further described below in conjunction with accompanying drawing.

Shown in Fig. 1～3, a kind of folder, comprise inner core 1, shell 2, described inner core 1 comprises inner casing 10, two locating pin structures, two springs 11 and a connection lead 12, described inner casing 10 articulates by a bearing pin 13 and shell 2, this inner casing 10 is provided with first through wires hole 14 and two spring registration arms 15 that are parallel to each other, described two locating pin structures are arranged at the axial both sides of spring registration arm 15, these two locating pin structures include fixed plate 16, left side locating dowel pin 17 and right locating dowel pin 18, described fixed plate is provided with through wires hole, described left locating dowel pin 17 and right locating dowel pin 18 are fixed in the two ends, the left and right sides in fixed plate 16 fronts, described two springs 11 are arranged in respectively in two spring registration arms 15, touch mutually with the two ends, the back side of two locating pin structure fixed plates 16 respectively at the two ends of these two springs 11, described connection lead 12 1 ends are fixed on the fixed plate 16, the other end passes the through wires hole and first through wires hole 14 of two fixed plates successively and fixes with the brake handle of bicycle, and the both sides up and down of described shell 2 are provided with first knock hole group 20 and the second knock hole group 21 suitable with locating dowel pin.

The both sides up and down of described shell 2 also are provided with the 3rd knock hole group 22, when inner core launches the 3rd knock hole group 22 and two right locating dowel pins 18 suitable; Angle α between described the 3rd knock hole group 22 and the first knock hole group 20 and the second knock hole group 21 is 130 °～150 °; Described angle α is 141 °.

The present invention installs a brake handle on handlebar, by totally four locating dowel pins (as Fig. 1) about in the connection lead pulling folded box, locating dowel pin is drawn close to the centre, the folded box shell is separated with inner core, reach folding effect, forward to (as Fig. 2,3) after the predetermined angle, wherein a pair of set pin self-orientation up and down is on the 3rd knock hole group of folded box shell, wherein the angle α between the 3rd knock hole group and the first knock hole group and the second knock hole group is preferably 141 °, make the two-wheeled of folding back car keep constant distance, can carry out bicycle.
