Description
The utility model relates to a kind of bicycle lock.
The bicycle rear axle lock of Chu Xianing mostly is by locking the purpose that a retainer of captiveing joint with rear axle reaches the locking rear axle in the market, and its structure is comparatively complicated.
It is a kind of simple in structure that the purpose of this utility model is to provide, and it is comparatively convenient that production is installed, and locking bolt can insert the band brake type bicycle automatic lock of slot automatically.
The purpose of this utility model is achieved in that the utility model comprises lockset head, locking bolt and retainer etc., its constructional feature is that retainer is the band-type brake hub that periphery is provided with slot, cam constitutes crank four jointed gear units by connecting rod, rocking arm and locking bolt, the lockset head internal cylinder is captiveed joint with cam, lock core rotates, and drives locking bolt and moves up and down by cam, connecting rod, rocking arm, and locking bolt moves down, can insert in the slot on the band-type brake hub locking band-type brake hub.
The utility model adds the precompressed stage clip between connecting rod and rocking arm, adopting between connecting rod and the rocking arm lives connects, one end of connecting rod is sleeved in the hole on the rocking arm; the rocking arm cam that rotates around the axis is provided with the corresponding elastic pressuring plate that is arranged on the lock housing with it of boss and is provided with scrobicular ring; add stage clip between locking bolt and the guide plate; cam rotation, in the scrobicular ring of boss turnover elastic pressuring plate, connecting rod drives locking bolt by rocking arm and moves up and down.
The rotating shaft of the utility model rocking arm is the brake facing rocker shaft.
The utility model is because retainer adopts the band-type brake hub that has slot, and the rotating shaft of rocking arm and brake facing rocking arm adopt same rotating shaft, and whole like this lock structure is simple, and it is comparatively convenient that production is installed.The utility model is because under opening, the boss on the cam is pressed in the scrobicular ring of elastic pressuring plate, and locking bolt presses down stage clip, and opening is stable.When lock core drive cam clockwise rotates, lock core is by the reach of cam driven connecting rod, because adopting to live with rocking arm, connecting rod is connected, connecting rod presses down the precompressed stage clip, and the precompressed stage clip promotes rocking arm, and rocking arm rotates along rotating shaft and presses down locking bolt, the band-type brake hub rotates, locking bolt enters in the slot under pressure automatically, finishes locking process, and is easy to use.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model running condition scheme drawing.
Accompanying drawing 3 is the utility model External view.
Accompanying drawing 4 is the utility model connecting rod and rocking arm connection diagram.
In the accompanying drawings, 1 contracting brake box, 2 band-type brake hubs, 3 slots, 4 scrobicular rings, 5 elastic pressuring plates, 6 boss, 7 cams, 8 connecting rods, 9 precompressed stage clips, 10 rocking arms, 11 rotating shafts, 12 adapter plates, 13 locking bolts, 14 stage clips, 15 guide pieces, 16 brake holding shoe plates, 17 brake facing rocking arms, 18 holes, 19 lockset heads.
Below in conjunction with accompanying drawing the utility model is described in detail:
Be the utility model opening scheme drawing as shown in Figure 1, the utility model is fixed on the car body by adapter plate 12 at contracting brake box 1, be provided with lockset head 19 in it, constitute one four jointed gear unit by cam 7, connecting rod 8, rocking arm 10 and locking bolt 13, its cam 7 and connecting rod 8 are hinged, and connecting rod 8 adopts to live with rocking arm 10 and is connected, and rocking arm 10 11 rotates around the shaft; rocking arm 10 and locking bolt 13 are hinged, and cam 7 is captiveed joint with the lock core in the lockset head 19.As shown in Figure 1, cam 7 rotates counterclockwise, and the boss 6 on the cam 7 enters in the scrobicular ring 4 on the elastic pressuring plate 5, drives locking bolt 13 by four jointed gear units and presses down stage clip 14, and lockset is opened.Shown in accompanying drawing 2,4, cam 7 clockwise rotates connecting rod 8 and moves along the hole on the rocking arm 10 18, press down precompressed stage clip 9; rocking arm 10 11 rotates around the shaft, press down locking bolt 13, locking bolt 13 can enter slot 3; if locking bolt 13 withstands on the outer edge of band-type brake hub 2; as long as promote bicycle, and locking bolt 13 is under the effect of precompressed stage clip 9, and meeting is inserted in the slot 3 automatically bicycle rear axle is locked.
