Description

Technical Field

[0001] The utility model relates to the technical field of floating joints, and particularly relates to a floating joint. Background Art

[0002] A floating joint is a commonly used accessory for cylinders. When the direction of the driving force of the cylinder and the force application point are not on the same straight line, the shaft rod is prone to deformation. The floating joint can be used to absorb or correct the offset, achieve flexible connection, protect the relevant components and equipment to operate smoothly, and extend the service life of the equipment. However, different cylinders often need to be equipped with corresponding types of floating joints. For example, when the connection end of the cylinder is a flange, an FLCF (flange connection type) floating joint is often used. When the connection end of the cylinder is a threaded rod, an FLCM (bolt connection type) floating joint is often used. Users often need to purchase multiple types of joints to meet the needs of different cylinders.

[0003] Vibrations and the like occurring during the use of the products in the prior art can cause the connections of nuts or bolts to become loose, and the hinge seat and the hinge seat bolt cannot rotate during use. Summary of the Utility Model

The other end of the bearing body is rotatably installed with a rotating shaft center through a third installation component.

[0007] Preferably, the first installation component includes two hinge seats and hinge seat bolts. The two hinge seats are movably arranged on the outer periphery of the connecting head. The hinge seat bolts are threadedly connected to one side of the connecting head, and one side of the hinge seat bolts is movably abutted against the housing.

[0008] Preferably, the bearing body includes a bearing and a bearing housing. The bearing is rotatably arranged inside the bearing housing.
