The specific embodiment
As depicted in figs. 1 and 2, lockable mechanism of the present utility model comprises a core 1, release wheel 2, set collar 4, jam plate 5, spring 7, miniature gears 6, shell 3 and roller 8, jam plate 5 is installed in the set collar 4 and but relative fixed ring 4 rotates, the two ends of each spring 7 connect a roller 8 respectively and constitute a spring roller member, a plurality of spring roller member are placed between jam plate 5 and the set collar 4, all have friction between each roller 8 and jam plate 5, the set collar 4.As shown in Figure 4, the outside of jam plate 5 has plane 50, and the spring roller member is placed between the circular arc inwall 41 of the plane 50 in the outside of jam plate 5 and set collar 4.
Miniature gears 6 has a junction 60, has spline on the connecting portion 60, and jam plate 5 centre holes are splined hole, miniature gears 6 with go back punch riveting after jam plate 5 keys are connected and fix.
As shown in Figure 4, these a plurality of spring roller member have this jam plate 5 of locking between jam plate 5 and set collar 4 and the latched position of set collar 4.This moment, roller 8 was under the effect of spring 7, be in end position, jam plate 5 is under the situation of moment of torsion less than predetermined value, the component of this predetermined torque on the spring direction can't overcome spring 7 elastic force and roller 8 and set collar 4, the summation of the friction force between roller 8 and the jam plate 5, jam plate 5 on cw and anticlockwise direction with respect to set collar 4 lockings.
Shown in Fig. 6-9, the non-circular hole 2-1 of the non-circular step 1-1 of axle core 1 and release wheel 2 is fixed towards rivet clasp.The end face of release wheel 2 stretches out a plurality of shift fork 2-2, and shift fork 2-2 is inserted into the gap between set collar 4 and the jam plate 5.As shown in Figure 5, there are two outsides of a spring roller member and two shift fork 2-2 that the radially extended projection 5-1 of jam plate 5 is arranged respectively between the two shift fork 2-2.
Closely cooperate and to relatively rotate between shell 3 and the set collar 4.A plurality of unguiculuses on the shell 3 are used for fixing lockable mechanism.Provide a plurality of position-limited troughs 40 on the circumference of set collar 4, and shell 3 inboards provide a plurality of spacing preiections 30, this spacing preiection 30 and these position-limited trough 40 joggles, thus shell 3 and set collar 4 can not relatively rotate.
In release, at first rotating shaft core 1, because taking turns 2 with release, axle core 1 rivets together, so, axle core 1 drives release wheel 2 and rotates together, the shift fork 2-1 of release wheel 2 meets the 8-1 in the roller 8 in rotation process, and the 8-1 in the driven roller 8 leaves end position, and release wheel 2 is rotated further, the 2-2 shift fork of release wheel 2 touches jam plate, and promoting jam plate 5 rotations, jam plate 5 drives miniature gearss 6 and rotates, and regulates and realizes.The same principle of reversing sense.
