Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution:

a swing arm of an automobile with enhanced pull-out force comprises a first support 1 and a lining 2, the right end of the first support 1 is fixedly connected with the lining 2, the inner side of the first support 1 is fixedly connected with a second support 3 through a first thread 11, the top end and the bottom end of the left lining 2 are fixedly connected with a first connecting block 5, the left end of the first support 1 is fixedly connected with a second connecting block 6, the inner sides of the first connecting block 5 and the second connecting block 6 are both slidably connected with a second thread 7, the other outer side of the second thread 7 is in threaded connection with a nut 13, the inner side of the second connecting block 6 is provided with a buffer block 8, the outer side of the first connecting block 5 is fixedly connected with a guide block 9, the pull-out force of the swing arm can be improved through the arrangement, thereby preventing the swing arm from being broken, the service life of the swing arm is prolonged, the left end of the second support 3 is fixedly connected with the lining 2, the inner side of the left lining 2 is fixedly connected with a ball head 4, the buffer block 8 is sleeved on the outer side of the second support 3, and the buffer block 8 is fixedly connected with a second rubber cushion 12, the buffer block can be quickly connected with the buffer rubber sleeve through a second thread 12, the buffer block 12, the buffer rubber sleeve 12 and the buffer rubber cushion rubber sleeve can be quickly connected with the buffer sleeve when the swing arm, the buffer rubber sleeve is connected with the second support through the buffer rubber sleeve 12, can be to making the swing arm when receiving stronger pulling force or extrusion through this kind of setting, play the effect of buffering to first screw thread 11, the number of first screw thread 11 is 4, and the number of second screw thread 7 and reset spring 10 is two, through this kind of setting, can improve the stability of whole swing arm.
