Abstract

The utility model discloses a tensile type ball hinged structure. The tensile type ball hinged structure comprises a ball type hinged joint, wherein a ball head of the ball type hinged joint is contained in a split type ball socket adaptive to the appearance of the ball head; a locking nut or sleeve is fixedly arranged at the outer side of the split type ball socket, a hinged bar of the ball type hinged joint extends out of the locking nut or sleeve; the aperture D1 of an opening of the split type ball socket is less than the diameter D2 of the ball head of the ball type hinged head. The tensile type ball hinge structure has the advantages of being simple and compact in structure, omitting the rolling and closing-in technique when the traditional ball hinged structure is manufactured, effectively improving the tensile capability of the ball hinged structure, and having higher tensile capability and reliability. The tensile type ball hinged structure is applied to ball hinged mechanisms of a compressor, a stop dog and the like for effectively preventing the pulling-out of the ball head and the ball socket, and is especially suitable for use environment in which the ball hinged structure can bear larger tensile and impact and higher reliability requirement.

Description

Tensile type ball-joint structure

Technical field

The utility model relates to the ball-joint structure of mechanisms such as being applied to compressor, stopper, especially relates to tensile type ball-joint structure.

Background technique

At present, the combination of the bulb of traditional ball-joint structure and ball-and-socket is to have closed up by the plastic deformation of ball-and-socket oral area material.The deficiency of its existence is: one,, due to the restriction of rolling beading technique, ball-and-socket closing in position part thickness is thinner, and the further attenuation of the wall thickness of part after rolling beading, has further weakened the load ability; Two, there is resiliently deformable in rolling beading part material inside, and this part distortion can slowly discharge, and the distortion of release will affect the reliability of Assembly of the parts; Three, outside, rolling beading position, without support member or structure, greatly reduces the extruding force of bearing.

Summary of the invention

The utility model purpose is to provide a kind of tensile type ball-joint structure.

For achieving the above object, the utility model is taked following technical proposals:

Tensile type ball-joint structure described in the utility model, comprise the globular hinge head, and the bulb of described globular hinge head is contained in the split type ball-and-socket adapted with its profile; The described split type ball-and-socket outside is fixed with locking nut or sleeve, and the hinge bar of globular hinge head extends outside described locking nut or sleeve; The hatch bore diameter D1 of split type ball-and-socket is less than the bulb diameter D2 of globular hinge head.

The utility model advantage is simple and compact for structure, and the rolling beading technique when having saved traditional ball-joint structure and manufacturing has effectively improved the ability of ball-joint structure bearing tension, has the de-ability of higher tension and reliability.Be applied to the ball-joint mechanisms such as compressor, stopper and can effectively prevent pulling of bulb and ball-and-socket, especially be suitable for the ball-joint structure and bear larger pulling force, impact force, Environmental Conditions that reliability requirement is higher.
