Abstract
The utility model provides a ball-joint and a connection unit composed of the ball-joint. Wherein, the ball-joint comprises a ball cup, a ball and a snap ring; the ball cup comprises a ball socket; the ball is rotatably fitted with the ball socket; and regularly distributed recesses and convexities matching with each other are formed on the ball socket inner surface and the ball external surface; a circular groove is formed on the ball cup external surface; the snap ring matches the groove to limit the ball into the ball socket; because the matched recesses and convexities are distributed regularly between the bulb and the ball socket, the ball can rotate rhythmically; and the fitting between the ball and the ball socket is uneasily skidded.
Description
Technical field
The utility model relates to a kind of turning joint, and particularly a kind of ball-joint, the utility model also relate to a kind of linkage unit of being made up of this ball-joint.
Background technique
Ball-joint is the mechanism's connected element that generally uses.Existing ball-joint generally comprises ball seat and spheroid of a dribbling nest, the rotating cooperation of spheroid and ball-and-socket.Yet the rotation of existing ball-joint does not have rhythm, can't accurate localization; The cooperation of spheroid and ball-and-socket is also skidded than being easier to.
In addition, the existing linkage unit of being made up of ball-joint just can not change length, thereby make troubles to use after in a single day making and finishing.
The model utility content
The utility model provides a kind of ball-joint, and its spheroid can rhythmically rotate, and the cooperation of spheroid and ball-and-socket is not easy to skid.
Described ball-joint comprises a ball seat, a spheroid and a snap ring.Ball seat comprises a ball-and-socket, and spheroid and ball-and-socket form rotating cooperation, is formed with the depression and the projection of the rule distribution that is fitted to each other on ball-and-socket internal surface and the outer surface of spheroid.Be formed with an annular groove on the ball seat outer surface, snap ring and annular groove cooperate, thereby spheroid is defined in the ball-and-socket.
Owing to the depression and the projection of the rule distribution that is fitted to each other are arranged between bulb and ball-and-socket, thereby spheroid can rhythmically rotate, and the cooperation between spheroid and ball-and-socket is not easy to skid.
The utility model also provides a kind of linkage unit, and it can change length easily.
Described linkage unit comprises a plurality of Couplings and a plurality of snap ring.Every suit fitting comprises a ball seat and a spheroid of connection fixed to one another, and ball seat comprises a ball-and-socket, is formed with depression and projection that corresponding each other rule distributes on ball-and-socket internal surface and the outer surface of spheroid, is formed with an annular groove on the ball seat outer surface.Wherein the ball-and-socket of the spheroid of a Coupling and another set of fitting forms rotating cooperation, and snap ring and annular groove cooperate, thereby spheroid is limited in the ball-and-socket.
Can change the number of Coupling as required, thereby change the length of Coupling.

Fig. 3 is the sectional view of Fig. 2.
The stereogram of the link that Fig. 4 is made up of a plurality of these ball-joints.
Embodiment
Please refer to Fig. 1, it has disclosed the ball-joint 10 of the utility model one preferred implementation.This ball-joint 10 comprises a ball seat 20, a spheroid 40 and a snap ring 30.
This ball seat 20 is incomplete spherical, comprises a ball-and-socket 21 and the annular groove 23 that is formed at the ball seat outer surface.Be formed with several rows equally distributed protruding 22 on ball-and-socket 21 internal surfaces.Annular groove 23 distributes along the diametric(al) of ball-and-socket 21, perhaps the opening of close ball-and-socket 21.
Be formed with on spheroid 40 outer surfaces and depressions 41 protruding 22 correspondences, equally distributed.
Please refer to Fig. 2, Fig. 3, when assembling, spheroid 40 is placed in the ball-and-socket 21, make projection 22 and depression 41 cooperate; Again snap ring 30 is placed in the annular groove 23, thereby spheroid 40 is defined in the ball-and-socket 21.
When spheroid 40 rotates in ball-and-socket 21, spheroid 40 and ball seat 20 elastically deformables, thus make projection 22 constantly from a depression 41, withdraw from, enter next depression 41 again, thereby realized rhythmical rotation.When rotation stopped, projection 22 was arranged in depression 41, thereby has realized accurate location.Because the cooperation of projection 22 and depression 41 has also prevented under the situation of not rotating, because spheroid 40 and ball-and-socket 21 cooperate the tight phenomenon such as skid that causes.
Please refer to Fig. 4, spheroid 40 and ball seat 20 can be fixed together, thereby form a Coupling 50, the socket each other of a plurality of Couplings 50, promptly wherein the ball-and-socket 20 of the spheroid 40 of a Coupling and another set of fitting forms rotating cooperation, snap ring 30 and annular groove 23 cooperate, thereby spheroid 40 is limited in the ball-and-socket 21.Thereby form a linkage unit 60.Can adjust the number of Coupling 50 according to actual needs, thereby obtain the linkage unit 60 of Len req easily.
It is disclosed that structure of the present utility model is not limited to present embodiment, and for example, projection 22 can be formed on the spheroid 40, corresponding, and depression 41 is formed on the internal surface of ball-and-socket 21.Spheroid 40 also can be connected other objects with ball seat 20.
