[0002] The ball joint realizes the transmission of power between different axes through the ball connection, provides multilateral rotation, can make the steering mechanism turn flat, and achieve vibration reduction and flat turning. The car ball joint is a kind of car part, also known as the universal joint, which refers to the mechanical structure that uses the ball to transmit power to different axes.

[0003] Nowadays, ball heads have different models depending on the environment. When the length model does not match, it cannot be used and needs to be replaced with the corresponding model, making it less versatile. Moreover, when the ball head is disassembled after being used for a long time, the ball head will stick to the ball head seat due to lubricating oil and other reasons. At this time, the ball head rod needs to be hammered to the ball head seat, which can easily cause damage to both. Utility Model Content

[0018] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0019] As shown in Figures 1-3, a telescopic ball head includes a ball head 10 and a mounting seat 11, wherein the ball head 10 is divided into a sphere and a column, wherein a telescopic rod 12 and a limit block are sleeved on the column, and a hammer assembly is provided in the ball head 10;

[0020] The telescopic assembly includes a striker 15 sliding in the ball head 10, the striker 15 is fixed to the inner wall of the telescopic rod 12 by a connecting rod 19, a striker block 14 is installed in the sphere of the ball head 10 by a tension spring, a force storage spring 18 is fixed between the end face of the striker 15 on one side close to the telescopic rod 12 and the inner wall of the ball head 10, a slide groove is provided on the top of the sphere of the ball head 10, the striker block 14 is located in the slide groove, the end face of the striker 14 on the side away from the striker 15 is a spherical surface, the radius of the spherical surface is consistent with the sphere of the ball head 10, the material of the striker block 14 can be one of resin and rubber, and the striker block 14 can effectively protect the mounting seat 11 and the ball head 10 from damage during disassembly.

[0021] A force storage chamber 17 is provided inside the column of the ball head 10, a through hole 16 is provided on the outer peripheral side of the column of the ball head 10, a connecting rod 19 is slidably installed in the through hole 16, a force storage spring 18 is located in the force storage chamber 17, an external thread is provided on the outer peripheral side of the column of the ball head 10, wherein the limiting block is a locking nut 13, the locking nut 13 is threadedly connected to the outer thread of the column of the ball head 10, two auxiliary fasteners 21 are fixed to the end face of the locking nut 13 on one side close to the telescopic rod 12, and two main fasteners 20 are fixed to the end face of the telescopic rod 12 on one side close to the locking nut 13, the main fastener 20 and the auxiliary fastener 21 are clamped with each other to limit the telescopic rod 12, and there is a large friction between the main fastener 20 and the auxiliary fastener 21, so that the two will not be easily separated.

[0022] During use, if the distance when the ball head is installed is not enough, it is necessary to pull the telescopic rod 12 through the connecting rod 19 to drive the firing pin 15 to compress the force storage spring 18 to extend the overall length of the ball head. When the installation distance is just enough, it is necessary to rotate the locking nut 13 until the secondary fastener 21 on the locking nut 13 is locked on the main fastener 20, so that the telescopic rod 12 stops sliding. At this time, the ball head can be installed, so that the ball head can continue to be used without replacing other types of ball heads, which greatly increases the versatility of the ball head.

[0023] When the ball head needs to be removed, the ball head is installed tightly and cannot be easily removed. At this time, the retaining nut 13 can be rotated to the bottom end close to the mounting seat 11, and then the telescopic rod 12 can be pulled away from the mounting seat 11 to compress the force storage spring 18 to the limit, and then the telescopic rod 12 is loosened. At this time, the telescopic rod 12 drives the striker 15 to directly hammer the impact block 14, so that the ball head 10 and the mounting seat 11 directly produce a large vibration. The tightly installed mounting seat 11 and the ball head 10 are gradually separated through the vibration, and then the disassembly can be easily completed. At the same time, it also effectively avoids the ball head from being damaged when the ball head is hammered with a tool.

[0024] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
