Description
The utility model relates to a kind of bicycle lock.
Shaft type bicycle lock kind in back is more at present, and its theftproof performance is good, but all there is complex structure in it, opens and the unsettled shortcoming of lock-out state.
The purpose of this utility model be to provide a kind of simple in structure, pick-proof is effective, unlatching and the stable back shaft type bicycle safe lock of lock-out state.
The purpose of this utility model is achieved in that the utility model comprises lockset head, locking bolt and the retainer of captiveing joint with bicycle rear shaft etc., its constructional feature is that retainer is a fluted disc that evenly is provided with slot along periphery, eccentric cam and locking bolt constitute piston crank mechanism, the lockset head internal cylinder is captiveed joint by bearing pin with cam, lock core rotates, move up and down by the cam driven locking bolt, locking bolt moves down the slot that can insert on the retainer, the locking retainer.
The upper end of the utility model locking bolt is sleeved in the grooved ring on the eccentric cam semicircle limit, and the locking bolt top is provided with locating dowel pin, and the lower end of locking bolt is sleeved on the guide piece, adds stage clip between locking bolt and guide piece.
Be provided with a boss in the grooved ring of the utility model on the cam limit, cam rotation, the locating dowel pin that is arranged on the locking bolt upper end is stuck in a side of boss.
The upper end of the utility model locking bolt is long flat column.
The utility model is owing to the upper end of locking bolt is sleeved in the semicircle grooved ring, add stage clip between the lower end of locking bolt and the spacer, the lock core Rotate 180 ° is finished and to be opened and locking, when unlatching and lock-out state, locking bolt is in apart from the lock core bearing pin and is respectively recently and the farthest, though adopt eccentric cam like this, opening under the effect of stage clip, in also can avoiding advancing because the possible of all standing appears in the overweight unexpected return of locking bolt that causes of severe jolt or key chain.Stage clip presses locking bolt downwards, and unlatching and lock-out state are stable like this, and pick-proof is effective.
Accompanying drawing 1 is the utility model cutaway view.
Accompanying drawing 2 is the utility model opening scheme drawing.
Accompanying drawing 3 is the utility model lateral plan.
Accompanying drawing 4 is the utility model External view.
Accompanying drawing 5,6 is the utility model cam and bolt structure scheme drawing.
Accompanying drawing 7 is the utility model locking bolt shape scheme drawing.
Below in conjunction with accompanying drawing the utility model is described in detail:
Shown in accompanying drawing 1,5, the utility model is in the lock state, promptly as shown in the figure, retainer 1 is captiveed joint with bicycle rear shaft 3, and lock core drives cam 7 and rotates, locking bolt 4 is in the effect of stage clip 5 is pushed down into slot 2 on the retainer 1, finish locking, can guarantee like this to lock when destroyed, locking bolt 4 still can not upspring, play the effect of pick-proof, increased integraty.Retainer 1 is captiveed joint with bicycle rear axle by bearing pin 3, and lockset head 14, bowl-shape eccentric cam 7, locking bolt 4, guide piece 6 etc. all are arranged on the base plate 8, are fixed on the car body by lock housing fixed connecting plate 9, and structure is comparatively simple.
Under state shown in the accompanying drawing 1, clockwise rotate 180 ° of lock cores, eccentric cam 7 is upwards mentioned locking bolt 4 like this, as shown in Figure 6, press down stage clip 5, slide in semicircle grooved ring 13 in locking bolt 4 upper ends, locating dowel pin 12 is stuck in a side of boss 10, at first because lock core rotates 180 °, locking bolt 4 moves to apart from lock core bearing pin 11 the most nearby by being in lock core bearing pin 11 farthest like this, even there is the downward pulling force of stage clip 5, locking bolt 4 can not move down yet, and opening is stable like this, secondly, because boss 10 is stuck in a side with the locating dowel pin on the locking bolt 4 12, plays better stabilization like this, can be because of causing locking bolt 4 unexpected returns the danger of all standing to occur owing to jolting in the driving process.
The utility model locking bolt 4 upper ends are flat column, can avoid locking bolt 4 that axial rotation takes place in grooved ring 13 like this.
