The utility model provides a two-way ratchet mechanism with rotary ratchets, which includes a ratchet, the ratchet is arranged on a pin shaft and can rotate around the pin shaft, the ratchet is covered with a protective shell, and the top of the protective shell is provided with a cylindrical opening. The cylindrical opening is provided with a rotary ratchet for turning the ratchet wheel. The design is reasonable, the structure is simple, the manufacture is convenient, the action is accurate, and the work is stable.
Description
Technical field
The utility model relates to intermittent movement field, is specifically related to turn round ratchet bidirectional 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 unidirectional pawl structures, and this ratchet mechanism operation precision is not high, and it is reasonable not to design, there is certain narrow limitation, because the shortcoming of above-mentioned instrument, it does not reach perfection inventor's thoughts, then exhausts the concentrated research of its intelligence and overcomes, with it, be engaged in this industry working experience for many years, and then develop revolution ratchet bidirectional ratchet mechanism, and utilize simply 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 revolution ratchet bidirectional ratchet mechanism, and reasonable in design, simple in structure, easily manufactured, action is accurate, working stability.
For solving above-mentioned existing technical problem; the utility model adopts following scheme: revolution ratchet bidirectional ratchet mechanism; comprise ratchet; described ratchet is located on bearing pin and can rotates around bearing pin; described ratchet overcoat has containment vessel; the top of described containment vessel is provided with cylindrical openings, and described cylindrical openings place is provided with stirs the revolution ratchet that ratchet rotates.
As preferably, described revolution ratchet upper end is fixed with turning axle, and on described turning axle, cover has returning spring.By adopting this set, reasonable in design, can realize the reset operation to turning axle.
As preferably, the upper end of described turning axle is fixed with the handle of easy-to-operat.By adopting this set, can easy-to-operat in work, easy to use, simple to operate.
As preferably, the both sides that are positioned at turning axle on described handle are fixed with two position-limited levers.By adopting this set, can carry out turning axle well spacingly, avoided turning axle to move in the process meta offset of rotating.
Beneficial effect:
The utility model adopts technique scheme that revolution ratchet bidirectional ratchet mechanism is provided, and has made up the deficiencies in the prior art, has improved economic benefit, and reasonable in design, simple in structure, easily manufactured, action is accurate, working stability.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, revolution ratchet bidirectional ratchet mechanism, comprises ratchet 1; described ratchet 1 is located on bearing pin 3 and can rotates around bearing pin 3; described ratchet 1 overcoat has containment vessel 4, and the top of described containment vessel 4 is provided with cylindrical openings 5, and described cylindrical openings 5 places are provided with stirs the revolution ratchet 2 that ratchet 1 rotates.Described revolution ratchet 2 upper ends are fixed with turning axle 6, and on described turning axle 6, cover has returning spring 7.The upper end of described turning axle 6 is fixed with the handle 8 of easy-to-operat.The both sides that are positioned at turning axle 6 on described handle 8 are fixed with two position-limited levers 9.
During real work, when stretching in the ratchet that inserts ratchet 1 and promote ratchet 1 from the cylindrical openings 5 of containment vessel 4, revolution ratchet 2 moves to a direction, while being compressed to certain state in the process that returning spring 7 rotates with revolution ratchet 2 and turning axle 6, being subject to restoring force to affect returning spring 7 upsprings, turning axle 6 rotates the direction that changes revolution sour jujube 2, in the ratchet of revolution ratchet 2 insertion ratchets 1, promoting ratchet 1 moves in the opposite direction, the upper end of turning axle 6 is provided with the handle 8 of easy-to-operat, the both sides that are positioned at turning axle 6 on handle 8 are fixed with carries out spacing position-limited lever 9 to turning axle 6, the deficiencies in the prior art have been made up, improved economic benefit, reasonable in design, simple in structure, easily manufactured, action accurately, 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.
