[0022] The present utility model will be further described below with reference to the drawings and embodiments:

[0023] An anti-seismic and anti-loosening bolt for a vehicle chassis, see Figures 1 to 4 , including a vehicle chassis bolt body 1, a limiting component 2 is arranged inside the vehicle chassis bolt body 1, and an adjusting mechanism 3 is arranged at the bottom end of the limiting component 2;

[0024] The adjusting mechanism 3 includes an adjusting frame 301. The adjusting frame 301 is sleeved on the outer side of the bottom of the limiting component 2. A number of clamping frames 302 are evenly distributed in a ring on the outside of the adjusting frame 301. An activity plate 303 is hinged inside the clamping frame 302. One end of the activity plate 303 away from the clamping frame 302 is hinged with an adjusting rod 304. Among them, both ends of the activity plate 303 can rotate along the inner sides of the clamping frame 302 and the adjusting rod 304 respectively. The clamping frame 302 is fixedly connected to the adjusting frame 301. Further, a slot for the movement of the adjusting rod 304 is provided on the surface of the automotive chassis bolt body 1. The adjusting rod 304 is fitted and engaged inside the slot. A convex thorn 305 is fixedly connected to one end of the adjusting rod 304 away from the activity plate 303. In the utility model, the upward movement of the limiting component 2 effectively drives the upward movement of the adjusting frame 301, thereby adjusting the angle of the activity plate 303, so that the activity plate 303 pushes the adjusting rod 304 to move outwards, facilitating the convex thorn 305 at the end of the adjusting rod 304 to move out and engage into the automotive chassis component, increasing the bolt fastening property and reducing the possibility of the bolt loosening due to vibration.

[0025] It should be noted that the limiting component 2 includes a threaded groove 201. The threaded groove 201 is opened on the inner side of the top of the automotive chassis bolt body 1. A threaded plate 202 is screwed inside the threaded groove 201. A vertical rod 203 is fixedly connected to the bottom end of the threaded plate 202. A clamping plate 204 is fixedly connected to the bottom of the vertical rod 203. Among them, the clamping plate 204 is engaged inside the adjusting frame 301. The vertical rod 203 and the adjusting frame 301 form a clamping and rotating structure through the clamping plate 204. Further, when the top of the threaded plate 202 is flush with the top of the automotive chassis bolt body 1, the threaded plate 202 drives the vertical rod 203, the clamping plate 204 and the adjusting frame 301 to move upward and the activity plate 303 is in a horizontal state. A limiting ring plate 205 is fixedly sleeved on the surface of the vertical rod 203. In the utility model, a cross tool is inserted into the inner side of the top of the threaded plate 202, and at the same time, the threaded plate 202 is rotated to move it up and down in the threaded groove 201, facilitating driving the clamping plate 204 and the adjusting frame 301 to move up and down, adjusting the height of the adjusting frame 301, thereby adjusting the inclination angle of the activity plate 303, and further controlling the horizontal movement state of the adjusting rod 304.

[0026] Working principle: Insert the cross tool into the inner side of the top of the threaded plate 202, and at the same time, screw the threaded plate 202 so that it is at the bottom of the threaded groove 201. At this time, the barbs 305 are not exposed. Then, install the automotive chassis bolt body 1 into the automotive chassis component. After installation, insert the cross tool into the inner side of the top of the threaded plate 202, and at the same time, screw the threaded plate 202 so that it is at the top of the threaded groove 201. The upward movement of the threaded plate 202 drives the clamping plate 204 and the adjusting frame 301 to move upward, adjusts the height of the adjusting frame 301, and thus adjusts the inclination angle of the movable plate 303, so that the movable plate 303 pushes the adjusting rod 304 to move outward. At this time, the barbs 305 at the end of the adjusting rod 304 move out and are stuck into the automotive chassis component, increasing the bolt fastening property and reducing the possibility of the bolt loosening due to vibration.

[0027] The embodiments disclosed in the present utility model are the preferred embodiments, but not limited thereto. Those of ordinary skill in the art can easily understand the spirit of the present utility model according to the above embodiments and make different extensions and changes. However, as long as they do not depart from the spirit of the present utility model, they are within the protection scope of the present utility model.
