Abstract

The invention discloses a tensile ball hinge structure. The structure comprises a ball-shaped hinge joint, wherein a bulb of the ball-shaped hinge joint is contained in a split type ball socket matched with the appearance of the bulb; lock nuts or a sleeve is fixed outside the split type ball socket; a hinge bar of the ball-shaped hinge joint extends out of the lock nuts or the sleeve; the opening aperture D1 of the split type ball socket is smaller than the bulb diameter D2 of the ball-shaped hinge joint. The structure has the advantages that the structure is simple and compact, the process of reducing by rolling during traditional ball hinged structure manufacturing is omitted, the capacity of the ball hinge structure in bearing tensile force is effectively improved, and the pull-out resistance capacity and the reliability are higher; when applied to ball hinge mechanisms such as compressors, stop dogs and the like, the ball hinge structure can effectively prevent pull out between the bulb and the ball socket and is especially suitable for the service environments in which the ball hinge structure bears higher tensile force and impact force and the reliability requirement is higher.

Description

Tensile type ball-joint structure

Technical field

The present invention relates to be applied to the ball-joint structure of the mechanisms such as compressor, stopper, especially relate 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 object of the invention is to provide a kind of tensile type ball-joint structure.

For achieving the above object, the present invention takes following technical proposals:

Tensile type ball-joint structure of the present invention, 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 invention has the advantages that simple and compact for structurely, the rolling beading technique when having saved traditional ball-joint structure and manufacturing, 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.
