Abstract
The utility model provides a double-pawl ratchet mechanism. The double-pawl ratchet mechanism comprises a ratchet, a plurality of ratchet teeth arranged on the ratchet, a pawl matched with the ratchet for operation, and a non-return pawl, wherein the ratchet teeth are respectively provided with a clamping groove. The double-pawl ratchet mechanism is reasonable in design, solid in structure, reliable in operation, high in operating efficiency, convenient to operate, safe to use, and capable of reducing potential safety hazards.
Description
Technical field
The utility model relates to mechanical engineering, especially dual pawl ratchet mechanism.
Background technique
Ratchet mechanism, a kind of one-way intermittent motion mechanism being formed by ratchet and pawl, ratchet mechanism is commonly used in the transposition of various lathes and the feeding of automaton discontinuous or rotary table, is also commonly used on jack.In bicycle, ratchet mechanism is for unidirectional drive, and in hand-operated winch, ratchet mechanism is conventional in case non-return turning.On ratchet, all can be provided with the ratchet gear teeth, the ratchet gear teeth are used unidirectional tooth conventionally, and ratchet is articulated with on rocking bar, when rocking bar counterclockwise swings, drive ratchet just to insert hook tooth to promote ratchet rotating in same direction, when rocking bar clockwise direction swings, ratchet slips on ratchet, ratchet stops operating, nonreversible in order to ensure ratchet, be everlasting on fixed component and install non-return ratchet additional, the reciprocally swinging of rocking bar can be by crankrocker mechanism, the realization such as gear mechanism and oscillating oil cylinder, when transmitting very low-power, also useful electromagnet directly drives ratchet, ratchet on current ratchet mechanism and the surface of contact of ratchet are all smooth, in ratchet operation, can skid at the right and left of ratchet unavoidably, ratchet just can not well be worked, reduce working efficiency, bring unnecessary impact, use inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of dual pawl ratchet mechanism easy to use, well-set.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: dual pawl ratchet mechanism, and comprise ratchet, be located at some ratchet gear teeth on ratchet, carry out the ratchet of auxiliary work, non-return ratchet with ratchet, the described ratchet gear teeth are provided with draw-in groove.
As preferably, described ratchet and non-return ratchet bottom are provided with fork, and described fork is connected and fixed by bolt and ratchet, non-return ratchet, makes integral body more firm, convenient work.
As preferably, described fork is provided with bearing, and ratchet is played to a fixing effect, makes integral body more firm.
Beneficial effect:
The utility model has adopted technique scheme that dual pawl ratchet mechanism is provided, and has made up the deficiencies in the prior art, reasonable in design, sound construction, and reliable operation, working efficiency is high, easy to operate, reduces potential safety hazard, uses safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, dual pawl ratchet mechanism, the ratchet 3, the non-return ratchet 4 that comprise ratchet 1, be located at some ratchet gear teeth 2 on ratchet 1, carry out auxiliary work with ratchet 1, the described ratchet gear teeth 2 are provided with draw-in groove 5, described ratchet 3 is provided with fork 6 with non-return ratchet 4 bottoms, described fork 6 is connected and fixed by bolt 7 and ratchet 3, non-return ratchet 4, and described fork 6 is provided with bearing 8.
During real work, in the middle of fork 6, be provided with bearing 8, can be fixed fork 6, on fork 6, by bolt 7, be fixed with ratchet 3 and non-return ratchet 4, make structure more firm, the bottom that is positioned at fork 6 is provided with ratchet 1, on ratchet 1, be provided with some ratchet gear teeth 2, ratchet 3 drives 2 rotations of the ratchet gear teeth, on each ratchet gear teeth 2, be provided with draw-in groove 5, ratchet 3 can be connected in the ratchet gear teeth 2 by draw-in groove 5, ratchet 3 is fixed, can avoid to the full extent ratchet 3 to slide on ratchet 1, increase soundness, what on fork 6, be positioned at ratchet 3 is also provided with below non-return ratchet 4, by non-return ratchet 4, can prevent that ratchet 1 from rotating backward, ratchet 3 is often stirred time ratchet gear teeth 2, non-return ratchet 4 will be fixed the ratchet gear teeth 2 of stirring at ratchet 3 accordingly below, avoid ratchet 1 reversion, increase working efficiency, reduce extra work labour force, easy to use.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
