One end of the ball pin protective cover 3 is fixed to the ball pin seat 1 through a first retaining ring 4, and the other end is fixed to the rod of the ball pin 2 through a second retaining ring 5.

[0024] In order to achieve a swing angle that cannot be achieved by the ball hinge in the prior art, the T-shaped ball hinge in this embodiment also includes two rotating bearings 6, and connecting arms 7 are respectively provided on the two rotating bearings 6; two mounting shafts 8 are symmetrically arranged on the ball head pin seat 1, and the two rotating bearings 6 are respectively arranged on the corresponding mounting shafts 8.

[0025] In order to enhance the connection strength between the ball pin seat 1 and the two mounting shafts 8 , in this embodiment, the two mounting shafts 8 are preferably provided integrally with the ball pin seat 1 .

[0026] The rotary bearing 6 in this embodiment includes a housing, a tapered hole ring 63 , a ball pin head 64 and a locking member 65 .

[0027] Among them, the shell is provided with a accommodating cavity (not shown in the figure) adapted to the ball pin head 64, and the opposite sides of the shell are respectively provided with a ball pin head entrance (not shown in the figure) and an installation port (not shown in the figure) connected to the accommodating cavity. The radial dimension of the ball pin head entrance is larger than the ball diameter of the ball pin head 64, and the radial dimension of the installation port is smaller than the ball diameter of the ball pin head 64. The shell is rotatably sleeved on the ball pin head 64 through the ball pin head entrance; the tapered hole ring 63 is arranged at the ball pin head entrance to prevent the shell from detaching from the ball pin head 64; the locking piece 65 passes through the installation port to fix the ball pin head 64 on the installation shaft 8.

[0028] In order to enhance the connection strength between the ball pin head 64 and the mounting shaft 8, in this embodiment, a mounting groove (not shown in the figure) is coaxially arranged on the ball pin head 64, and a through hole (not shown in the figure) is coaxially arranged in the mounting groove, and a threaded hole 81 is coaxially arranged at the end of the mounting shaft 8; the mounting shaft 8 passes through the tapered hole ring 63 and is inserted into the mounting groove, and the locking piece 65 passes through the mounting port and the through hole in sequence and is threadedly connected to the threaded hole 81.

[0029] In order to solve the problem of loosening of threads due to vibration in the prior art, in this embodiment, the mounting groove is preferably a frustum-shaped groove, and the end of the mounting shaft 8 adopts a frustum-shaped shape that matches the mounting groove.

[0030] The locking member 65 in this embodiment is a bolt. In actual applications, a screw may also be used, which is not limited in this embodiment.

[0031] To facilitate processing, the shell in this embodiment adopts a split structure, including an inner shell 61 and an outer shell 62 fixedly mounted from the inside to the outside, the accommodating cavity, the ball pin head entrance and the installation port are all arranged on the inner shell 61, and the connecting arm 7 is arranged on the outer shell 62.
