Description

The automatic buckling and locking device of folding bicycle

Technical field

The utility model relates to a kind of automatic buckling and locking device that is used for folding bicycle.

Background technology

Latching structure on the existing Collapsible bicycle adopts bolt-type, when folding and opening bicycle, need manually extract or insert latch, wastes time and energy; Long-term use causes galling, and stability reduces, thereby is not easy to popularize.

The utility model content

The utility model purpose is to provide a kind of automatic buckling and locking device for the deficiency that solves above-mentioned technology, makes folding bicycle convenient to use.

In order to achieve the above object, technical scheme provided by the utility model is: the automatic buckling and locking device of a kind of folding bicycle, automatically buckling and locking device is installed on the cycle rack, it comprises handle, axle, bayonet lock, spring, armed lever, first clamp and second clamp, a sidewall of second clamp is fixed on the after poppet, one end of another sidewall and bale handle is hinged, its bottom has draw-in groove, and the other end of bale handle is hinged on the first clamp top, and the outer wall and the central sill of described first clamp are affixed, the bottom of first clamp is packed on the back rest, its inwall bottom is provided with draw-in groove, is coated with one on the back rest, and armed lever is installed on the axle, the one end is equipped with handle, the other end is equipped with bayonet lock, and spring one end is connected on the bayonet lock, and the other end is connected on the inner bottom surface of first clamp.

Further, armed lever installs the two ends at axle respectively.

Further, armed lever is L shaped.

The utlity model has following advantage: the utility model simple structure, easy to use, make folding bicycle folding and convenient and swift when opening; After the bicycle locking, it is reliable and stable that car load is connected, and guarantees riding safety; Avoid bicycle because of the loosening phenomenon of long-term use fixed position, good stability, safe.

Description of drawings

Fig. 1 the utility model is installed in the structural representation on the bicycle rack;

Fig. 2 the utility model partial enlarged drawing;

Fig. 3 folding bicycle frame uses structural representation of the present utility model;

Wherein: 1 handle, 2,3 bayonet locks, 4 springs, 5 armed levers, 6 first clamps, 7 second clamps, 8 draw-in grooves, 9 central sills, 10 bale handles, 11 back rest, 12 after poppets.

The specific embodiment

Below in conjunction with the description of drawings specific embodiment of the present utility model.

As Fig. 1, Fig. 2 and shown in Figure 3, the automatic buckling and locking device of a kind of folding bicycle, automatically buckling and locking device is installed on the cycle rack, it comprises handle 1, axle 2, bayonet lock 3, spring 4, armed lever 5, the first clamps 6 and second clamp 7 is characterized in that: a sidewall of second clamp 7 is fixed on the after poppet 12, one end of another sidewall and bale handle 10 is hinged, its bottom has draw-in groove 8, and the other end of bale handle 10 is hinged on first clamp, 6 tops, and the outer wall of first clamp 6 and central sill 9 are affixed, the bottom of first clamp 6 is packed on the back rest 11, its inwall bottom is provided with draw-in groove 8, is coated with one 2 on the back rest 11, and armed lever 5 is installed on the axle 2, the one end is equipped with handle 1, the other end is equipped with bayonet lock 3, and spring 4 one ends are connected on the bayonet lock 3, and the other end is connected on the inner bottom surface of first clamp 6.

Armed lever 5 installs the two ends at axle 2 respectively.

Armed lever 5 is L shaped.

The utility model in use, bicycle opens, bayonet lock 3 is stuck in the draw-in groove 8 of first clamp 6, during bicycle folding, pull handle 1, bayonet lock 3 is broken away from from the draw-in groove 8 of first clamp 6, upwards mention the d joint on the bicycle back rest 11, drive the bicycle back rest 11 and move up, drive bicycle central sill 9 simultaneously and bale handle 10 moves up, after poppet 12 is moved forward, under the effect of spring 4, bayonet lock 3 snaps in the draw-in groove 8 of second clamp 7 automatically, with the bicycle locking, and can not open easily; When bicycle opens, pull handle 1, bayonet lock 3 leaves the draw-in groove 8 of second clamp 7, promote bicycle after poppet 12 it is moved backward, when hand leaves handle, automatic pop into position, bicycle central sill 9 and bale handle 10 move down, simultaneously, the bicycle back rest 11 moves down, under the effect of frame frame self gravitation and spring 4, bayonet lock 3 snaps in the draw-in groove 8 of first clamp 6 automatically, with the bicycle locking, bayonet lock 3 can not break away from draw-in groove 8, guarantees riding safety.

Fixing when the utility model is applied to folding bicycle and launches and turn up, the fixed form that the folded bicycle that breaks traditions is loaded down with trivial details, actv. has played that the customer is convenient when using folded bicycle, safety and quick-folding, fixing performance, and practicality is extremely strong.
