Detailed description of the invention
As Figure 1-3, a kind of Lever Blocks quickly regulates chain device, including cylinder block set 1, ratchet 2, ratchet 3, spine
Latch spring 4 and detent pin 5；Described cylinder block set 1 includes for the clamping part 101 of fixed pawl spring one end and is available for inserting institute
State the installing hole 102 of detent pin 5；Described ratchet 2 is arranged on the jack shaft 7 of cylinder block set 1, can not send out with described jack shaft 7
Life relatively rotates, the jack shaft of Lever Blocks is also arranged with brake disc and friction plate, because friction plate, ratchet, jack shaft
All locked by brake disc, so brake disc, friction plate, ratchet, jack shaft can see all-in-one-piece, pin ratchet and make it not
Rotate, then other part can not rotate.
As Figure 4-Figure 6, described ratchet 3 includes location division 301, connecting portion 302 and lever portion 303；Described connecting portion 302
Including manhole, it is used for being fixed on described installing hole 102 through described detent pin 5；Described location division 301 is bending,
Insert on the tooth of described ratchet 2, make ratchet by the resistance of location division, it is impossible to rotate；When described location division 301 and described ratchet
2 contact time, described lever portion 303 away from described ratchet 2, location division under the effect of ratchet spring normality for being stuck on ratchet,
Making ratchet to turn clockwise, but can not rotate counterclockwise, lever portion is as the spanner of ratchet, and shifting lever portion can be complete
Location division is become to depart from ratchet.
Described detent pin 5 sequentially passes through described connecting portion 302 and ratchet spring 4, enters described installing hole 102；Described spine
One end of latch spring 4 is inserted in described clamping part 101, and the other end acts in described lever portion 303, and lever portion can have
One groove, is used for accommodating the ratchet spring other end；Drive described location division 301 by lever portion 303, make location division 301 to leaning on
Move in nearly described ratchet 2 direction, it is ensured that the normality of location division is to contact with ratchet, the teeth directional of ratchet counterclockwise deflection, fixed
After position portion and tooth contact, the detent pin counter clockwise direction in location division, to one, location division support force, makes the ratchet can not be to the inverse time
Move in pin direction.
One of them specific embodiment, as it is shown in figure 1, opposition is arranged with two structural walls in parallel on described cylinder block set 1
6, form clamping part 101 between two described structural walls 6, one end of ratchet spring is inserted and between two structural walls, limits it certainly
By rotating, the one end completing ratchet spring is fixed.After installation, described location division 301 and described lever portion 303 lay respectively at described
Ratchet 2 cross-section center and the both sides of described installing hole 102 cross-section center line.Institute is inserted in one end of described ratchet spring 4
Stating in clamping part 101, the other end acts in described lever portion 303, makes lever portion 303 move to away from described ratchet 2 direction,
Move near described ratchet 2 direction in described location division 301.As Fig. 2 be ratchet by ratchet locking state figure, shown in Fig. 3, move
Lever portion makes ratchet turn clockwise, and ratchet is unclamped by ratchet so that it is be freely rotatable.
Specifically, described location division 301, connecting portion 302 and lever portion 303 are one-body molded.The thickness of described connecting portion 302
Less than described location division 301 and the thickness of described lever portion 303, facilitate the fixing of ratchet spring in the vertical direction so that it is no
Arbitrarily skew.
Embodiment described above is only to be described optimal way of the present utility model, not to of the present utility model
Scope is defined, and on the premise of without departing from this utility model design spirit, those of ordinary skill in the art are new to this practicality
Various deformation that the technical scheme of type is made and improvement, all should fall into the protection domain that this utility model claims determine
In.
