Description

A kind of bicycle folder

Technical field

The utility model relates to a kind of folder, particularly a kind of bicycle folder.

Background technology

At present, folding bicycle is because of little, the easy to carry favor that is subjected to people day by day of parking space.Fig. 1 is the scheme drawing of known bicycle folder.This folder includes a pedestal 102 and an articulation piece 103, the affixed first vehicle frame bar 104 of these Connection Block 102 1 ends, the affixed second vehicle frame bar 105 of these articulation piece 103 1 ends, this articulation piece 103 is that hinge connects with these Connection Block 102 1 ends, the other end Fast detachable unit 106 that on articulation piece 103, is hinged, these Connection Block 102 suitable places establish a fluting 107, make this articulation piece 103 be incorporated into this Connection Block 102, this first bar 104 is linked to each other with this second bar 105 be a straight line, pull this Fast detachable unit 106, articulation piece 103 is limited to this Connection Block 102.

Though above-mentioned known folder can provide folding effect, has following shortcoming, when rainwater or dust infiltration folder, folder is dirty easily, even gets rusty, and makes folder not attractive in appearance, and will reduce the producer's industrial competitiveness.Known design is not a perfect design, does not quite meet the industry utilization, so necessity of the improvement of being researched and developed is arranged.

The utility model content

The utility model aims to provide a kind of bicycle folder, and its folding operation is quick, and degree of safety is higher, can prevent that rainwater and dust from entering, and simple in structure, practical, is easy to processing and manufacturing.

The technical scheme that its technical matters that solves the utility model adopts is: include box and inner box outside a side pivotally attached, described outer box and inner box are individually fixed in the body front and rear sections, described outer box and inner box all are provided with recess at hinged heteropleural end, crossbeam is sheathed on the described indent on two articulation pieces simultaneously, and inner box and outer box are fixed.

In the described inner box inner chamber pedestal is set, described pedestal has centre hole, screw bolt passes spring, centre hole, crossbeam, and the bolt front end is connected in loam cake.

Described crossbeam is arranged between loam cake and the pedestal, and described spring is arranged between bolt and the pedestal.

Described body is cycle frame or standpipe of bicycle.

The utility model bicycle folder is provided with groove and is stuck in this groove by cross bar on inner box and outer box, inner box and outer box closely are fixed together the degree of safety height; This folder inner box, outer box own simple in structure is easy to processing and manufacturing; Be provided with loam cake in inner box, outer box upper end, not only make rainwater and dust be difficult for entering folder inside and cause erosion, and spur and upward to be somebody's turn to do, the inner box of folder, outer box are separated, realize the very practicality of function of fast folding.

The specific embodiment

Below in conjunction with accompanying drawing the utility model bicycle folder is described in further details.

Folder is a kind of folder that is used in bicycle in the technical program, and the vehicle frame of folding bicycle constitutes by two sections, comprises between

first vehicle frame

4,5, two sections vehicle frames of second vehicle frame folder is installed.

Inner box 2, the first vehicle frames 4 one ends that are installed with folder as Fig. 2-5, the second vehicle frame 5 one ends are installed with the outer box 1 of folder, and the inner box 2 of folder is provided with axis hole 24, and the outer box 1 of folder is provided with through hole 13, and axis hole 24 is worn with axis hole 13 usefulness axostylus axostyles 6 and is hinged; Loam cake 3, crossbeam 10, spring 9, bolt 8 coaxial series connection connect together.In inner box 2 inner chambers pedestal 21 is set, this pedestal 21 has centre hole 211, and above-mentioned bolt 8 passes this centre hole 211 and is connected in loam cake 3, and for example bolt 8 is used thread connection with loam cake 3.This crossbeam 10 is arranged between loam cake 3 and the pedestal 21, and this spring 9 is arranged between bolt 8 and the pedestal 21.Described inner box 2 upper ends are provided with inner box recess 22, and described outer box 1 upper end also is provided with outer box recess 11, and when outer box 1 and inner box 2 closed up, outer box recess 11 cooperatively interacted with the position of inner box recessed 22, and this recess is arc, V-type, U type or trapezoidally all can.

Axostylus axostyle 6 is as hinge, and its locking can have multiple mode, and for example, axostylus axostyle 6 front ends have outside thread, and axostylus axostyle 6 pins its front end by nut after passing outer box and inner box; Perhaps, as Fig. 4, axostylus axostyle 6 front ends have negative thread, after axostylus axostyle 6 passes outer box and inner box, pass through 7 lockings of lock bolt at the other end.

Described inner box 2 outer wall both sides are inner box plane 25, and the opposite position madial wall that outer box 1 fastens the inner box plane 25 of inner box 2 is outer box plane 16, its objective is folder is opened or when closing up, reduce friction, more smooth and easy, in addition, after making that folder fastens, can circumferentially not rotate.Described recess 22 is arranged at this 25 upper ends, inner box plane, and this axis hole 24 is arranged at this inner box plane 25 lower position.

Crossbeam 10 is done the motion of axostylus axostyle 6 in opposite directions under the effect of spring 9, be absorbed in outer box recess 11 and the inner box recess 22 fastening inner box 2 and outer box 1 simultaneously.When bicycle need fold, the power that imposes was given loam cake 3, make its prolong axis do with respect to axostylus axostyle 6 away from motion, to remove the tightening force of inner box 2, outer box 1, just can open folder, realize the folder function of bicycle.

Among another embodiment, this folder can be used for the standpipe of bicycle position, and the structure of folder itself is with above-mentioned embodiment, and its difference is, the inner box 2 and the outer box 1 of folder is individually fixed on upper and lower section of vertical tube.

The inner box 2 of folder can be replaced with the relative position of outer box 1 in the various embodiments described above.
