Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides an embodiment: the utility model provides a antifriction bearing is bearing steel pipe for lasso, including frame 1, the inside of frame 1 evenly is equipped with multiunit spring 4, the outside of spring 4 is equipped with inner loop bar 5, the bottom in the 5 outsides of inner loop bar is equipped with outer tube 3, the bottom of outer tube 3 is equipped with splint 6, can play the effect of centre gripping to the bearing, the bilateral symmetry at splint 6 top articulates there is hinge bar 7, improve the stability of connecting, the inside of frame 1 evenly is equipped with multiunit spout 2, hinge bar 7 is located the inside of spout 2.

Further, the top of hinge rod 7 is equipped with the stopper, and the stopper is located the inside of spout 2, and the convenience is spacing to hinge rod 7's position, prevents that hinge rod 7 from dropping from the inside of spout 2.

Further, the clamping plate 6 is made of an arc-shaped structure, and is convenient to be matched with a bearing.

Furthermore, the outside of frame 1 is equipped with the protection line, and the bilateral symmetry at frame 1 top is equipped with the connecting hole, improves the joint strength after frame 1 installs.

Further, splint 6's inboard evenly is equipped with the multiunit recess, and the recess is the arc structure for splint 6 can effectively connect the inside ball of bearing.
