Abstract
The utility model discloses an inversion stopper, which comprises a swing rod, a driving pawl, a ratchet wheel, a stopping pawl and a stander, wherein the swing rod is sleeved on an O shaft of the stander; the ratchet wheel is fixedly connected with the O shaft of the stander; and the driving pawl is connected with the swing rod and forms a rotary pair with the swing rod. The inversion stopper can prevent inversion of machinery, which is caused by gravity, has a simple structure and is operated flexibly and conveniently and high in safety.
Description
Technical field
The utility model relates to a kind of contrary stopper.
Background technique
In daily life, the employed machine of people often should be in operation and the time can't load self gravitation and occur reversing, and causes the generation of peril.
The model utility content
The model utility purpose: the purpose of the utility model is in order to solve the deficiency of existing technology, the contrary stopper that provides.
Technological scheme: in order to realize above purpose, the described a kind of contrary stopper of the utility model 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 the structural representation of the utility model;
Wherein: 1. rocking bar 2. drives ratchet, 3. ratchet, 4. detent, 5. frame, 6. reed.
Embodiment
Further illustrate the utility model 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 machine that stops that applying 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 the technical conceive and the characteristics of explanation the utility model, its objective is to let to be familiar with the also enforcement according to this of content that these those skilled in the art can understand the utility model, can not limit the protection domain of the utility model with this.All equivalents or modifications of having done according to the utility model spirit all should be encompassed within the protection domain of the utility model.
Claims (3)
