Abstract
The invention discloses a reversion stopper, which comprises a rocker, a driving pawl, a ratchet wheel, a stopping pawl and a frame, wherein the rocker is hollowly sleeved on an O shaft of the frame, the ratchet wheel is fixedly connected with the O shaft of the frame, and the driving pawl is connected with the rocker so as to form a rotary pair. The reversion stopper is capable of preventing reversion generated due to self gravity, simple in structure, flexible and convenient in operation and high in safety.
Description
Technical field
The present invention relates to a kind of contrary stopper.
Background technique
In daily life, the employed machine of people often occurs reversing because when operation, can't load self gravitation, causes the generation of peril.
Summary of the invention
Goal of the invention: the objective of the invention is in order to solve the deficiency of existing technology, a kind of contrary stopper is provided.
Technological scheme: in order to realize above purpose, a kind of contrary stopper of the present invention comprises rocking bar; Drive ratchet, ratchet, detent; Frame, described rocking bar sky are enclosed within on the O axle of frame, and described ratchet becomes to be fixedly connected with the O axle of frame; Drive ratchet and be connected, and form rotary pair with it with rocking bar.
Contact for described detent is remained with ratchet, described detent outside is provided with a reed.
More firm for rocking bar is connected with the driving ratchet, described rocking bar is connected with rivet with the driving ratchet.
Beneficial effect: a kind of contrary stopper, can prevent the reverse that machinery produces because of deadweight, simple in structure, flexible and convenient operation, safe.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Wherein: 1. rocking bar 2. drives ratchet, 3. ratchet, 4. stop gear, 5. frame, 6. reed.
Embodiment
Further illustrate the present invention below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of contrary stopper comprises rocking bar, drives ratchet; Ratchet, detent, frame; Described rocking bar sky is enclosed within on the O axle of frame, and described ratchet becomes to be fixedly connected with the O axle of frame, drives ratchet and is connected with rocking bar; And form rotary pair with it, and described detent outside is provided with a reed, and described rocking bar is connected with rivet with the driving ratchet.
A kind of contrary stopper that applies on the lift when rocking bar 1 is done the clockwise direction swing, drives ratchet 2 and inserts in ratchet 3 teeth groove; And drive ratchet 3 and turn over certain angle along clockwise direction, when rocking bar 1 when counterclockwise rotating, drive ratchet 2 and on the back of tooth of ratchet 3, slip over; The gear transfixion contacts for detent 4 is remained with ratchet 3, is provided with a reed 6 in detent 4 outsides;, detent 4 will stop ratchet 3 not driven ratchet 2 drives two generation turning anticlockwises motions, like this; When rocking bar 1 was made continuous reciprocally swinging, ratchet 3 just can only be done the rotation of unidirectional stepping, produces reverse and be unlikely to lift because of deadweight;, improved the safety in the machine running process.
The foregoing description only is explanation technical conceive of the present invention and characteristics, its objective is to let to be familiar with these those skilled in the art and can to understand content of the present invention and enforcement according to this, can not limit protection scope of the present invention with this.All equivalents that spirit has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
Claims (3)
