Detailed Description

The following detailed description of the utility model is provided in connection with the accompanying drawings to facilitate understanding and grasping of the technical scheme of the utility model.

Referring to fig. 1 and 3, a rod end joint movable bearing comprises a joint bearing body 1, wherein a round head 2 is arranged at the end part of the joint bearing body 1, the round head 2 is in a flat round shape, a rotating shaft 4 is arranged below the round head 2, a ball head 41 is arranged at the end part of the rotating shaft 4, the ball head 41 is in a round ball shape, a round head groove 44 is formed in the center of the ball head 41, the round head 2 is inserted into the round head groove 44, the joint bearing body 1 rotates in the round head groove 44 along the center of the round head 2 as a rotation axis to adjust an included angle between the bearing body and an end rod, and in this example: the first through hole 42 that the level set up has been seted up on the platform 411, the second through hole 21 of looks adaptation has been seted up at the center of button head 2, wear to be equipped with fastening bolt 3 between first through hole 42 and the second through hole 21, for convenient installation of fastening bolt 3, be provided with platform 411 respectively in the both sides of bulb 41, reduce the width of button head groove 44 through screwing fastening bolt 3, button head groove 44 inner wall and button head 2 surface contact, fastening bolt 3 screws up the pressure that the contact surface that tightens button head groove 44 and button head 2 surface received more, the frictional force that the contact surface received is bigger simultaneously, thereby reach the rotation of restriction whole joint bearing body 1. After the round head 2 and the ball head 41 are matched and rotate, a certain gap is reserved between the upper end of the ball head 41 and the contact surface of the end part of the joint bearing body 1, and a certain gap is reserved between the lower end of the round head 2 and the contact part of the round head groove 44, so that interference between the round head and the ball head during rotation is prevented.
