[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figures 1-3 The image shows a rocker arm structure for automatic locks on trucks.

[0019] Example 1: Includes a rocker arm 1, a connecting plate 3, an annular plate 4, and a connecting mechanism 5. The rocker arm 1 provides support for the rocker arm ring 2, the connecting plate 3 provides support for the rocker arm ring 2, and the annular plate 4 provides support for the connecting plate 3. The rocker arm ring 2 is located above the rocker arm 1. The connecting plate 3 is fixedly connected to the bottom of the rocker arm ring 2, and the annular plate 4 is fixedly connected to the bottom of the connecting plate 3. The connecting mechanism 5 is located between the rocker arm 1 and the annular plate 4. The connecting mechanism 5 is used to separate the rocker arm 1 from the rocker arm ring 2 for replacement of the rocker arm ring 2.

[0020] Furthermore, the connecting mechanism 5 includes a docking plate 51, an assembly plate 52, a mounting groove, and a locking assembly. The docking plate 51 facilitates the connection between the rocker arm 1 and the annular plate 4 to support the installation of the rocker arm 1. The assembly plate 52 facilitates the connection between the annular plate 4 and the docking plate 51 to position the installation of the annular plate 4. The docking plate 51 is fixedly connected to the top of the rocker arm 1 and is located at the bottom of the annular plate 4. The assembly plate 52 is fixedly connected to the bottom of the annular plate 4. The mounting groove is opened at the top of the docking plate 51, and the assembly plate 52 is slidably inserted into the inner cavity of the mounting groove. The locking assembly is located on the docking plate 51 and is used to fix the assembly plate 52 to the docking plate 51.

[0021] Furthermore, the connecting mechanism 5 also includes a reinforcing plate 58 and a sliding groove. The reinforcing plate 58 is beneficial for reinforcing the installation of the annular plate 4 and the docking plate 51.

The top of the docking plate 51 is provided with a first sliding groove that cooperates with the reinforcing plate 58. The sliding grooves are symmetrically opened on the top of the docking plate 51.

[0022] Specifically, the locking assembly includes a movable plate 53 and a locking pin 54. The movable plate 53 facilitates the movement of the locking pin 54, making it easy to pull the locking pin 54. The locking pin 54 helps to limit the relative position of the assembly plate 52 and the docking plate 51, thereby facilitating the installation or disassembly of the docking plate 51 and the annular plate 4 to connect or separate the rocker arm ring 2, making it easy to replace the rocker arm ring 2 as needed. The movable plate 53 is slidably inserted into the inner cavity of the sliding groove. The locking pin 54 is fixedly connected to the side of the movable plate 53. A second sliding groove is provided on the side of the inner wall of the mounting groove. The locking pin 54 is slidably inserted into the inner cavity of the second sliding groove. A positioning groove that cooperates with the locking pin 54 is provided on the side of the assembly plate 52.

[0023] More specifically, the locking assembly also includes a drive member and a guide plate 57. The guide plate 57 facilitates the horizontal guidance of the sliding of the moving plate 53. The drive member is located on the docking plate 51. The guide plate 57 is fixedly embedded in the sliding groove. The side of the moving plate 53 has a through groove that cooperates with the guide plate 57.

[0024] Example 2: Based on Example 1, the driving component includes a connecting seat 55 and a driving column 56. The connecting seat 55 facilitates the movement of the movable plate 53, making it easy to drive the movable plate 53. The driving column 56 facilitates the movement of the movable plate 53, so that the movable plate 53 drives the locking column 54 to connect or separate from the assembly plate 52. The connecting seat 55 is fixedly connected to the side of the movable plate 53. The end of the driving column 56 is rotatably connected to the inside of the connecting seat 55. A T-shaped groove is opened on the side of the inner wall of the sliding groove. The driving column 56 is threadedly inserted into the inner cavity of the T-shaped groove.
