Abstract

The utility model provides a dual drive ratchet mechanism comprising a swing rod, a first ratchet pawl and a second ratchet pawl that are disposed on the swing rod, and a ratchet wheel under the two ratchet pawls. The two ratchet pawls drive in the same direction. The dual drive ratchet mechanism, reasonable in design, firm in structure, reliable in work and high in work efficiency, is convenient to operate and safe to use, and allows safety hidden troubles to be reduced.

Description

Dual Drive ratchet mechanism

Technical field

The utility model relates to mechanical engineering, especially Dual Drive 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, and ratchet stops operating, and current ratchet mechanism is nonreversible in order to ensure ratchet, conventionally all can on fixed component, install non-return ratchet additional, although can effectively prevent like this ratchet reversion, be provided with the rotational velocity that non-return ratchet tend limits ratchet, reduce the working efficiency of ratchet, in ratchet rotation process, conventionally all can there is the phenomenon that ratchet pauses, ratchet can not continuous operation, reduces working efficiency, uses inconvenient.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of easy to use, Dual Drive ratchet mechanism of increasing work efficiency.

For solving above-mentioned existing technical problem, the utility model adopts following scheme: Dual Drive ratchet mechanism, comprise fork, be located at the first ratchet, the second ratchet on fork and be located at the ratchet below two ratchets, described the first ratchet and the second ratchet are done in the same way and are driven.

As preferably, described the first ratchet and the second ratchet are fixed by screw and fork, and ratchet is fixed on fork, convenient ratchet are driven.

Beneficial effect:

The utility model has adopted technique scheme that Dual Drive 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 Drive ratchet mechanism, comprise fork 1, be located at the first ratchet 2, the second ratchet 3 on fork 1 and be located at the ratchet 4 below two ratchets, described the first ratchet 2 and the second ratchet 3 are done in the same way and are driven, and described the first ratchet 2 and the second ratchet 3 are fixed by screw 5 and fork 1.

During real work, fork 1 is provided with the first ratchet 2 and the second ratchet 3, the first ratchet 2 and the second ratchet 3 are all fixed by screw 5 and fork 1, make structure more firm, below fork 1, be provided with ratchet 4, fork 1 carries out orderly moving up and down, in fork 1 movement process, the first ratchet 2 also can move along with the motion of fork 1, fork 1 often moves up and down one time, the first ratchet 2 just drives once ratchet 4, when the first ratchet 2 is driven into bottom, in the time of need to doing return movement, being located at the first ratchet 2 the second ratchet 3 below also can be followed by ratchet 4 is driven, not only can prevent that ratchet 4 from reversal phenomenon occurring, and can guarantee that ratchet 4 can all rotate all the time, the first ratchet 2 and the second ratchet 3 cooperatively interact, without any confusion, increased greatly the working efficiency of ratchet 4, 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.

Claims
