The ball-joint seatTechnical field
The present invention relates to mechanical field, relate in particular to a kind of ball-joint seat.
Background technique
In life, many times need ball-joint, so that make the object that is installed on the ball-joint realize freely swinging of a plurality of directions, but can realize that at present the main devices of this function is a universal joint.The shortcoming of universal joint is that axial dimension is bigger, and cost is higher.
Summary of the invention
The object of the invention is exactly bigger in order to solve existing technology universal joint axial dimension, and the cost problem of higher; A kind of ball-joint seat is provided; Have compact structure, manipulate laborsaving, the advantage of good reliability.
For realizing above-mentioned purpose, the present invention adopts following technical proposals:
A kind of ball-joint seat comprises pedestal, spheroid, and carriage, the spherical inner chamber of pedestal cooperates with outer surface of spheroid is movable, and pedestal is connected with carriage, and spheroid is provided with fixedly column casing.
The annular pass is established in the carriage centre, is provided with passage in the annular pass in the middle of pedestal and the carriage to be ball movingly.
Fixedly column casing is provided with tapped hole, establishes fixing bolt on the tapped hole.In the fixedly column casing of spheroid, install mast during application, tight a bolt, can realize the motion of ball-joint.
Beneficial effect of the present invention: compact structure, manipulate laborsaving, the advantage of good reliability.
Description of drawings
Fig. 1 is the structural principle schematic representation of ball-joint seat of the present invention;
Fig. 2 is the plan view of Fig. 1.
Wherein, 1 bolt, 2 fixing column casings, 3 spheroids, 4 carriages, 5 balls, 6 pedestals.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
A kind of ball-joint seat, as shown in Figure 1, comprisepedestal 6;Spheroid 3,carriage 4, the spherical inner chamber ofpedestal 6 cooperates withspheroid 3 outer surfaces are movable;Pedestal 6 is connected withcarriage 4, it is characterized in that,spheroid 3 is provided with fixedlycolumn casing 2; Annular passs are established incarriage 4 centres, are provided with passage in the annular pass in the middle ofpedestal 6 and thecarriage 4 to beball 5 movingly.Fixedlycolumn casing 2 is provided with tapped hole, establishes fixingbolt 1 on the tapped hole.When using, only need in the fixedlycolumn casing 2 ofspheroid 3, to install a mast, tight abolt 1, can realize the motion of ball-joint.
Though the above-mentioned accompanying drawing that combines is described the embodiment of invention; But be not restriction to protection domain of the present invention; One of ordinary skill in the art should be understood that; On the basis of technological scheme of the present invention, those skilled in the art need not pay various modifications that creative work can make or distortion still in protection scope of the present invention.
