Description
Technical field
The utility model relates to the engaging and disengaging gear field, is specifically related to a kind of claw type engaging and disengaging gear, is applicable to torque transmission and other torque transmission occasion of push rod in the stop valve.
Background technique
At present, in the situation that the spool of stop valve advances, when the rotary drive bar advances spool, and reach spool and in valve body, during the stroke top, if continue the rotary drive bar, then can run into larger rotational resistance, easily damage simultaneously drive link and spool, if but drive link is not pressed on spool on the valve body, may cause the not thorough of valve body internal channel shutoff, cause the leakage between the valve body internal channel.
The model utility content
The purpose of this utility model is the problems referred to above that are for the prior art existence, and a kind of claw type engaging and disengaging gear is provided, and can conveniently advance the spool in the stop valve, reduces simultaneously the infringement to drive link and spool.
Above-mentioned purpose of the present utility model is achieved through the following technical solutions:
A kind of claw type engaging and disengaging gear, comprise push rod, also comprise handwheel, cylinder base, attachment post, the first dog-clutch, the second dog-clutch and elastic component, the cylinder base top is connected with handwheel, the cylinder base bottom end opening, the first dog-clutch is for annular and be fixed on the cylinder base bottom, attachment post one end passes the first dog-clutch and extend in the cylinder base and be provided with block, the second dog-clutch is for annular and be set in the attachment post the other end, push rod is connected with attachment post, elastic component be set on the attachment post and two ends respectively with block be connected dog-clutch and be connected, the first dog-clutch bottom surface is provided with the first claw type tooth, and the end face of the second dog-clutch is provided with the second claw type tooth adaptive with the first claw type tooth.
Aforesaid elastic component is the butterfly reed.
Aforesaid the first claw type tooth and the second claw type tooth are the right-angled trapezium tooth.
The utility model compared with prior art has the following advantages:
1, simple in structure, easy to use;
2, can realize that torsion advances, and reduces simultaneously to being pushed into the infringement of thing and drive link.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the view of the first dog-clutch of the present utility model and the second dog-clutch cooperating;
Fig. 3 is another view of the first dog-clutch of the present utility model and the second dog-clutch cooperating.
Among the figure: the 1-handwheel; The 2-cylinder base; The 3-attachment post; 4-the first dog-clutch; 5-the second dog-clutch; The 6-block; The 7-elastic component; The 8-push rod; 401-the first claw type tooth; 402-the first trapezoidal chamfer surface; 501-the second claw type tooth; 502-the second trapezoidal chamfer surface.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described in further detail.
Such as Fig. 1～shown in Figure 3, a kind of claw type engaging and disengaging gear, comprise push rod 8, also comprise handwheel 1, cylinder base 2, attachment post 3, the first dog-clutch 4, the second dog-clutch 5 and elastic component 7, cylinder base 2 tops are connected with handwheel 1, cylinder base 2 bottom end openings, the first dog-clutch 4 is for annular and be fixed on cylinder base 2 bottoms, attachment post 3 one ends pass the first dog-clutch 4 and extend in the cylinder base 2 and be provided with block 6, the second dog-clutch 5 is for annular and be set in attachment post 3 the other ends, push rod 8 is connected with attachment post 3, elastic component 7 be set on the attachment post 3 and two ends respectively with block 6 be connected dog-clutch 4 and be connected, the end face that the first dog-clutch 4 bottom surfaces are provided with the first claw type tooth 401, the second dog-clutches 5 is provided with the second claw type tooth 501 adaptive with the first claw type tooth 401.Elastic component 7 is the butterfly reed.The first claw type tooth 401 and the second claw type tooth 501 are the right-angled trapezium tooth.Handwheel 1, cylinder base 2, attachment post 3, the first dog-clutch 4, the second dog-clutch 5 and push rod 8 are all coaxial.
Before use, the second claw type tooth 501 on the first claw type tooth 401 on the first dog-clutch 4 and the second dog-clutch 5 is fitted.In use, rotation hand wheel 1, handwheel 1 drive cylinder base 2 rotations and drive simultaneously 4 rotations of the first dog-clutch.The first trapezoidal chamfer surface 402 on the first claw type tooth 401 acts on the second trapezoidal chamfer surface 502 on the second claw type tooth 501, produces circumferential spin, drives 5 rotations of the second dog-clutch, and the second dog-clutch 5 drives push rod 8 and is rotated.When the rotational resistance of push rod 8 during greater than certain limit value, the first trapezoidal chamfer surface 402 and the second trapezoidal chamfer surface 502 can slide in dislocation, prevent push rod 8 and are pushed into the infringement of thing.
Specific embodiment described herein only is 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 replenishes 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.
