At this time, the anti-skid pad under the top sheet is in close contact with the bottom wall of the groove. When the car generates vibration while running and the plug column is subjected to a deflection force in the circumferential direction, the anti-skid pad and the bottom wall of the groove generate friction, thereby preventing the plug column from being deflected. At the same time, the groove on the top sheet is aligned with the through hole, and the locking block is turned. The locking block rotates eccentrically around the fixed axis. After the locking block rotates, it extends into the groove through the through hole, thereby radially locking the top sheet. When the car generates vibration while running and the plug column is subjected to an upward thrust, the plug column is prevented from moving upward, thereby achieving a firm connection under the vibration of the car running for a long time.

[0007] With the above technical solution, when the locking block extends into the groove, the magnetic block can be firmly adsorbed by the magnet, so that the locking block is circumferentially locked, thereby enhancing the firmness of the automobile buckle connection.

[0008] As a further optimization of the present invention, a plurality of anti-slip strips are provided at the bottom of the anti-slip pad, and the plurality of anti-slip strips extend along the radial direction of the top sheet and are equidistantly distributed along the circumferential direction of the top sheet.

[0009] As a further optimization of the present invention, at least two connecting grooves are provided and are equidistantly distributed along the circumference of the baffle.

[0010] By adopting the above technical solution, a plurality of locking blocks are evenly distributed along the circumferential direction, so that the top plate can be firmly locked in all directions, thereby enhancing the firmness of the automobile buckle connection.

[0011] As a further optimization of the present invention, a plurality of anti-slip grooves are provided at the end of the locking block along the circumferential direction.

[0012] By adopting the above technical solution, when the locking block is manually turned to rotate, the anti-skid groove can prevent slipping, thereby improving the convenience during installation and improving the installation efficiency.

[0013] The beneficial effects of the utility model are as follows: during installation, the plug post is rotated, and the socket moves downward through the thread and extends into the inclined groove, so that the expansion sheet is squeezed to become tilted and expand. At this time, the anti-skid pad under the top sheet is in close contact with the bottom wall of the groove. When the car generates vibration while running and causes the plug post to be subjected to a deflection force in the circumferential direction, the anti-skid pad and the bottom wall of the groove generate friction, thereby preventing the plug post from being deflected. At the same time, the groove on the top sheet is aligned with the through hole, and the locking block is turned. The locking block rotates eccentrically around the fixed axis, and after the locking block rotates, it extends into the groove through the through hole, thereby radially locking the top sheet. When the car generates vibration while running and causes the plug post to be subjected to an upward thrust, the plug post is prevented from moving upward, thereby achieving a firm connection under the vibration of the car running for a long time.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0023] See attached Figure 3-7The embodiment disclosed in the utility model is further provided with: a firmly connected automobile buckle, comprising a baffle 1 and a plug post 2, a screw hole 12 is provided at the center of the baffle 1, a plurality of expansion sheets 11 are provided below the baffle 1, an inclined groove 111 connected to the bottom of the screw hole 12 is provided on the inner side of each expansion sheet 11, a top sheet 21 is provided on the top of the plug post 2, the plug post 2 is provided with an external thread and is threadedly connected to the screw hole 12, and a groove 13 for accommodating the top sheet 21 is provided on the top of the baffle 1;

[0024] The bottom of the top sheet 21 is provided with an anti-skid pad 211. Specifically, the bottom of the anti-skid pad 211 is provided with a plurality of anti-skid strips 2111. The plurality of anti-skid strips 2111 extend along the radial direction of the top sheet 21 and are equidistantly distributed along the circumferential direction of the top sheet 21.

[0025] An annular groove 3 is circumferentially provided at the end of the top sheet 21, and at least two connecting grooves 4 are equidistantly provided at the end of the baffle 1 along the circumferential direction; it also includes a through hole 5 connecting the connecting groove 4 with the annular groove 3, each connecting groove 4 is provided with a vertical fixed shaft, and the fixed shaft is provided with a locking block 6 that can be rotated in a biased direction, and the locking block 6 can pass through the through hole 5 and extend into the annular groove 3 by rotating to achieve radial locking of the top sheet 21.

[0026] Furthermore, a magnet 31 is provided on the inner wall of the annular groove 3 , and a magnetic block 62 is provided on one end of the locking block 6 away from the fixed axis. Specifically, the magnetic block 62 is embedded in the upper surface and the lower surface of the locking block 6 .

[0027] The principle of the utility model is: when installing, the plug post 2 is rotated, and the socket moves downward through the thread and extends into the inclined groove 111, so that the expansion piece 11 is squeezed to tilt and expand;

[0028] At this time, the anti-skid pad 211 under the top sheet 21 is in close contact with the bottom wall of the groove 13. When the car generates vibrations while driving and the plug post 2 is subjected to a deflection force in the circumferential direction, the anti-skid pad 211 and the bottom wall of the groove 13 generate friction, thereby preventing the plug post 2 from being deflected.

[0029] At the same time, the groove 13 on the top sheet 21 is aligned with the through hole 5, and the locking block 6 is manually turned. The anti-skid groove 61 can prevent the hand from slipping against the locking block 6. Then the locking block 6 rotates eccentrically around the fixed axis. After the locking block 6 rotates, it extends into the groove 13 through the through hole 5, thereby radially locking the top sheet 21. When the locking block 6 extends into the groove 13, the magnetic block 62 can be firmly adsorbed with the magnet 31, so that the locking block 6 is circumferentially locked, thereby enhancing the firmness of the car buckle connection. When the car vibrates while driving and the plug post 2 is subjected to an upward thrust, the plug post 2 is prevented from moving upward, thereby achieving a firm connection under the vibration of the car running for a long time.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications of the above assumptions should also be regarded as the protection scope of the present invention.
