Abstract
The utility model provides a bidirectional ratchet wheel mechanism. The bidirectional ratchet wheel mechanism comprises a support, a pawl arranged on the support, a ratchet wheel arranged at the bottom of the support and matched with the pawl, and a bearing, wherein the bearing is arranged in the middle of the ratchet wheel in a sleeved mode; the pawl is fixedly arranged on the support. The bidirectional ratchet wheel mechanism is reasonable in design, firm in structure, reliable in work, high in working 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, for easy to use, a lot of local meetings adopt bidirectional ratchet, present bidirectional ratchet mechanism all needs to be provided with two mutual alternations of ratchet substantially in order to stir ratchet, make its rotation, but being provided with two ratchets can make whole ratchet seem to seem heavier, and can relatively waste resource, cause unnecessary waste, affect workmanship, use inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of bidirectional ratchet mechanism easy to use, well-set.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: bidirectional ratchet mechanism, comprise support, be located at ratchet on support, be located at the ratchet that frame bottom and ratchet cooperatively interact and be enclosed within the bearing in the middle of ratchet, on described support, be fixed with a ratchet.
As preferably, described ratchet driving pawl left-right rotation, can bi-directional drive ratchet by ratchet, easy to use.
As preferably, described ratchet and support are fixed by screw, and ratchet is fixed on support, can more effectively work.
As preferably, described ratchet pressed on ring is arranged with some draw-in grooves that cooperatively interact with ratchet, and ratchet can promote ratchet by the draw-in groove on ratchet.
Beneficial effect:
The utility model has adopted technique scheme that bidirectional 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, bidirectional ratchet mechanism, comprise support 1, be located at ratchet 2 on support 1, be located at the ratchet 3 that support 1 bottom and ratchet 2 cooperatively interact and be enclosed within the bearing 4 in the middle of ratchet 3, on described support 1, be fixed with a ratchet 2, described ratchet 2 driving pawl 3 left-right rotation, described ratchet 2 is fixed by screw 5 with support 1, and described ratchet 3 pressed on rings are arranged with some draw-in grooves 6 that cooperatively interact with ratchet 2.
During real work, on support 1, by screw 5, be fixed with ratchet 2, bottom at support 1 is worn and is inserted with ratchet 3 by bearing 4, ratchet 3 is provided with some draw-in grooves 6, the ratchet 2 being located on support 1 can rotate by draw-in groove 6 driving pawls 3, when needs carry out bi-directional drive to ratchet 3, take support 1 as cutting lines, ratchet 2 can be rotated around support 1 by screw 5, can drive the ratchet 3 of support 1 both sides, as long as be provided with a ratchet 2, just can realize bi-directional drive, increase working efficiency, 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.
