Specific embodiment
The present invention will be further described for explanation and specific embodiment with reference to the accompanying drawing.
As shown in Figures 1 to 4, a kind of novel ratchet device comprising substrate 1 is rotatably equipped in 1 side of substrate
Self-locking plate 2, the self-locking plate 2 are equipped with L shape self-locking grooves 21, and driving self-locking plate 2 is additionally provided on the self-locking plate 2 and rotates self-locking spine
Take turns mechanism 3.
Specifically, as shown in Figures 1 to 4, the ratchet mechanism 3 includes ratchet 31, wind spring 32, latch mechanism 33, described
Ratchet 31 is fixedly installed in 2 top of self-locking plate and concentric with the shaft of self-locking plate 2, and the wind spring 32 is installed in ratchet 31, uses
It is rotated in driving pawl 31, the latch mechanism 33 is installed on 1 side of substrate, for lockking or unclamping ratchet 31.
Specifically, as shown in Figures 1 to 4, the latch mechanism 33 includes movable latch 331, friction lever 332, plate washer
333, the first spring 334, movable friction component 335, the plate washer 333, which is placed in above ratchet 31, is fixedly installed in 1 side of substrate,
It is described activity latch 331 be fixedly installed under movable friction component 335,334 elasticity of the first spring press on plate washer 333 with
Between movable friction component 335, the activity friction component 335 is equipped with friction pulley 3351, and the friction lever 332 is loosened across shelves
The friction pulley 3351 of plate 333 and movable friction component 335 forms friction pair and loosens protrudes substrate 1 across movable latch 331 again
Bottom a distance.
Specifically, as shown in Figures 1 to 4, the movable friction component 335 includes friction pulley 3351, sliding seat 3352, pressure
Plate 3353, second spring 3354, pushing block 3355, the vertical middle part of the sliding seat 3352 are equipped with vertical through slot, the sliding seat
3352 upper transverse portions are equipped with block, and 3352 transverse lower portion of sliding seat is equipped with convex, and the pushing block 3355 is fixedly installed in work
The convex of dynamic 3352 two sides of seat, described 3353 one end of pressing plate and sliding seat 3352 is rotatablely connected, and 3353 other end of pressing plate is set
