Abstract
The utility model provides a multi-pawl ratchet wheel mechanism. The multi-pawl ratchet wheel mechanism comprises a rotating shaft, a ratchet wheel and a plurality of ratchets, wherein the ratchet wheel is arranged on the rotating shaft, the ratchets are arranged on the outer surface of the ratchet wheel, a swing plate is arranged on the rotating shaft, a plurality of pawls matched with the ratchets are ranked on the swing plate, and the pawls are rotationally arranged on the swing plate through hinge pins and can rotate around the hinge pins. The multi-pawl ratchet wheel mechanism is reasonable in design, simple in structure, easy to manufacture, convenient to use, accurate in motion and stable in working.
Description
Technical field
The utility model relates to intermittent movement field, is specifically related to multijaw ratchet mechanism.
Background technique
Ratchet mechanism is a kind of simple intermittent motion mechanism, and it will rotate continuously or to-and-fro motion converts unidirectional step motion to.What existing ratchet mechanism adopted mostly is single pawl structures, this ratchet mechanism operation precision is not high, and it is reasonable not to design, because the shortcoming of above-mentioned instrument, it does not reach perfection inventor's thoughts, then exhaust the concentrated research of its intelligence and overcome, with it, be engaged in this industry working experience for many years, and then develop multijaw ratchet mechanism, utilize simple design, can make the utility model reach easy to operate, operate steadily, safe and reliable effect.
Summary of the invention
Technical problem to be solved in the utility model is to provide grabs ratchet mechanism more, reasonable in design, simple in structure, easy to manufacture, easy to use, and action is accurate, working stability.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: multijaw ratchet mechanism, comprise rotating shaft, be arranged on ratchet in rotating shaft, be arranged on the some ratchets on ratchet outer surface, in described rotating shaft, be also provided with pendulum plate, on described pendulum plate, row is provided with some ratchets that coordinate with ratchet, and described ratchet is turned and is located on pendulum plate and can rotates around bearing pin by bearing pin.
As preferably, described ratchet adopts three, is followed successively by from left to right the first ratchet, the second ratchet and the 3rd ratchet.By adopting this set, reasonable in design, compact structure, action is accurate, working stability, mechanical efficiency is high.
As preferably, described pendulum plate adopts sector.By adopting this set, easy to manufacture, working effect is obvious.
As preferably, between described rotating shaft and ratchet, be arranged with bearing.By adopting this set, can reduce the wearing and tearing between rotating shaft and ratchet, extend the working life of rotating shaft and ratchet, reduce consuming cost, increase economic efficiency.
Beneficial effect:
The utility model adopts technique scheme that multijaw ratchet mechanism is provided, and has made up the deficiencies in the prior art, has improved economic benefit, reasonable in design, simple in structure, easy to manufacture, easy to use, and action is accurate, working stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, multijaw ratchet mechanism, comprise rotating shaft 1, be arranged on ratchet 2 in rotating shaft 1, be arranged on the some ratchets 3 on ratchet 2 outer surfaces, in described rotating shaft 1, be also provided with pendulum plate 4, on described pendulum plate 4, row is provided with some ratchets that coordinate with ratchet 3, and described ratchet is turned and is located on pendulum plate 4 and can rotates around bearing pin 5 by bearing pin 5.Described ratchet adopts three, is followed successively by from left to right the first ratchet 6, the second ratchet 7 and the 3rd ratchet 8.Described pendulum plate 4 adopts sector.Between described rotating shaft 1 and ratchet 2, be arranged with bearing 9.
During real work, ratchet 2 and pendulum plate 4 are arranged in rotating shaft 1, on pendulum plate 4, by bearing pin 5, turn and be provided with ratchet, when pendulum plate 4 swings according to counter clockwise direction, drive ratchet to insert ratchet 3 and promote ratchet 2 rotating in same directions, when pendulum plate 4 swings according to clockwise direction, ratchet slips on ratchet 2, ratchet 2 stops operating, and in order to improve the degree of regulation of mechanism, adopts the ratchet mechanism of three ratchets, the deficiencies in the prior art have been made up, improved economic benefit, reasonable in design, simple in structure, easy to manufacture, easy to use, action is accurate, working stability.
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.
