Position be mutually perpendicular to, be drilled with circular hole at the medial surface top of lower universal base, lower rotational pin is the most mounted within the bore,
Forming revolute pair with lower universal base, be drilled with circular hole bottom the medial surface of upper universal base, upper rotational pin is i.e. arranged on
In this hole, form revolute pair with upper universal base.
The gap width of described lower universal base is more than the width of upper universal base, under the gap width of upper universal base is more than
The width of universal base.
The bottom of described expansion link arranges spring.
Owing to have employed above technical scheme, present invention have the advantage that
Use sleeve, mandrel, thrust pin, expansion link, lower universal base, cuboid, upper universal base, lower rotation
The extension type universal coupling that pin, upper rotational pin, spring combine designed, milling on the periphery of sleeve
Having elongated slot, be possible to prevent expansion link to skid off sleeve, the upper and lower side of this groove is milled into semicircle so that thrust pin with
The contact surface of groove top or bottom land is big, and stress is relatively small, and thrust pin and groove end face are all less likely to occur to damage, long
Lower rotational pin and upper rotational pin in cube are mutually perpendicular to, and lower rotational pin and lower universal base form revolute pair, up to ten thousand
Form revolute pair to seat with upper universal base, turning of any direction between upper universal base and lower universal base, can be realized
Dynamic, cannot will not work, at the bottom of expansion link owing to producing interference each other between lower universal base and upper universal base
The elastic force of the spring that portion is arranged can realize universal joint easily along axial the elongating or shortening of expansion link.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect,
Below in conjunction with being specifically illustrating, the present invention is expanded on further.
A kind of extension type universal coupling, including sleeve 1, mandrel 2, thrust pin 3, expansion link 4, down ten thousand
To seat 5, cuboid 6, upper universal base 7, lower rotational pin 8, upper rotational pin 9, spring 10, sleeve 1 is empty
Core structure, its bottom lock, in the soleplate between position secure mandrel 2, the outside of mandrel 2 is cased with spring 10,
Expansion link 4 is also hollow structure, is enclosed within the outside of mandrel 2, and the bottom of expansion link 4 contacts also with spring 10
Extrusion spring 10, is provided with a thrust pin 3 bottom the outer round surface of expansion link 4, and lower universal base 5 is fixed
At the top of expansion link 4, being connected by lower rotational pin 8 with cuboid 6, cuboid 6 leads to upper universal base 7
Cross rotational pin 9 to connect.
On the periphery of sleeve 1, milling has elongated slot, and this groove runs through the periphery of sleeve 1, and thrust pin 3 is i.e. set in
In this groove, can move up and down along groove, when expansion link 4 moves to top, keep off at this thrust pin 3
The top of groove, prevents expansion link 4 from skidding off sleeve 1.
The upper and lower side of the elongated slot on sleeve 1 periphery is milled into semicircle, owing to thrust pin 3 is cylindrical, because of
This contact surface when thrust pin 3 moves to groove top or bottom land is big, and stress is relatively small, thrust pin 3 and groove end face
All it is less likely to occur to damage.
Cuboid 6 left and right side and front and back sides are respectively provided with lower rotational pin 8 and upper rotational pin 9, and two rotate
The position of pin is mutually perpendicular to, and is drilled with circular hole at the medial surface top of lower universal base 5, and lower rotational pin 8 is i.e. arranged on
In this hole, form revolute pair with lower universal base 5, bottom the medial surface of upper universal base 7, be drilled with circular hole, upper turn
Untie-sell 9 is that is mounted within the bore, forms revolute pair with upper universal base 7, then go up universal base 7 and lower universal base 5
Between can realize the rotation of any direction.
The gap width of lower universal base 5 is more than the width of upper universal base 7, and the gap width of upper universal base 7 is more than
The width of lower universal base 5, will not be dry owing to producing between upper and lower universal base when producing relative motion between them
Disturb and cannot work.
The bottom of expansion link 4 arranges spring 10, when need universal joint expansion link 10 axially need elongation or
During shortening, can be realized easily by the elastic force of spring 10.
Extension type universal coupling disclosed in this invention, on the periphery of sleeve 1, milling has elongated slot, permissible
Preventing expansion link 4 from skidding off sleeve 1, the upper and lower side of this groove is milled into semicircle so that thrust pin 3 and groove top or
The contact surface of bottom land is big, and stress is relatively small, and thrust pin 3 and groove end face are all less likely to occur to damage, cuboid
Lower rotational pin 8 and upper rotational pin 9 on 6 are mutually perpendicular to, and lower rotational pin 8 forms revolute pair with lower universal base 5,
Upper universal base 7 forms revolute pair with upper universal base 7, can realize appointing between upper universal base 7 and lower universal base 5
Meaning direction rotation, between lower universal base 5 and upper universal base 7 will not due to produce each other interference and cannot
Work, the elastic force of the spring 10 arranged bottom expansion link 4 can realize universal joint easily along expansion link 4
Axial elongates or shortens.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The industry
Skilled person will appreciate that, the present invention is not restricted to the described embodiments, described in above-described embodiment and description
The principle that the present invention is simply described, the present invention also has respectively without departing from the spirit and scope of the present invention
Planting changes and improvements, these changes and improvements both fall within scope of the claimed invention.Application claims is protected
