[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example:

[0024] Reference Figure 1-5 The present invention discloses a pre-tightened automotive connecting nut plate, including an automotive nut plate body 1 and a threaded post 2 fixedly connected to its upper end. A connecting nut 3 is threadedly connected to the circumferential side of the threaded post 2. The lower end of the threaded post 2 is open. An anti-detachment block 11 is provided inside the automotive nut plate body 1. Both sides of the anti-detachment block 11 are provided with snap-fit ​​parts.

[0025] The snap-fit ​​component includes a rectangular groove 12 and a snap-fit ​​spring 13. The rectangular groove 12 is opened on one side of the anti-detachment block 11. The snap-fit ​​spring 13 is fixedly connected to one side wall of the rectangular groove 12. A circular snap-fit ​​block 15 is fixedly connected to the other side of the snap-fit ​​spring 13, and the circular snap-fit ​​block 15 moves through one side of the connecting nut 3.

[0026] In this embodiment, the connecting nut 3 is threaded onto the surface of the threaded post 2. When the connecting nut 3 cannot rotate, the circular locking block 15 is contracted into the rectangular groove 12 by the force of the threaded post 2, and pushes the anti-disengagement block 11 downward. When the locking spring 13 reaches the groove of the connecting nut 3, the locking spring 13 recovers due to its own elasticity, and pushes the circular locking block 15 into the connecting nut 3, thereby realizing the insertion of the circular locking block 15 into the connecting nut 3, preventing the connecting nut 3 from sliding after long-term use, which affects the tightness of the connection. Preferably, the connecting nut 3 can be fixed to the external connecting parts, thereby realizing the fixing of the connecting parts to the car nut plate body 1. The car nut plate body 1 can be welded to the car body or threaded through the threaded groove (7).

[0027] For further details, please refer to Figure 4 The upper end of the main body 1 of the car nut plate has two moving grooves 5. The side walls of the moving grooves 5 are slidably connected to the mounting sliders 6, and the upper end of the mounting sliders 6 has a threaded groove 7. An adjustment mechanism 9 is provided between the mounting sliders 6 and the moving grooves 5 for adjusting the position of the mounting sliders 6.

[0028] In this embodiment, the mounting slider 6 can be adjusted within the movable groove 5, thereby adjusting the position of the threaded groove 7. The position of the threaded groove 7 can be adjusted according to the installation position.

[0029] For further details, please refer to Figure 5 The adjusting mechanism 9 includes an adjusting groove 901 and a lead screw 902. The adjusting groove 901 is opened on one side wall of the moving groove 5. The lead screw 902 is rotatably connected between the side walls of the adjusting groove 901. The mounting slider 6 is threadedly connected to the circumferential side of the lead screw 902 through the lead screw nut 903.

[0030] In this embodiment, the mounting slider 6 can slide between the side walls of the moving groove 5. When the lead screw 902 is rotated, the lead screw nut 903 moves on the circumferential side of the lead screw 902. The mounting slider 6 slides with the lead screw nut 903. The mounting slider 6 can adjust its position within the moving groove 5, thereby adjusting the position of the threaded groove 7. The position of the threaded groove 7 can be adjusted according to the installation position. Preferably, an anti-slip rotating block 904 is fixedly connected to the circumferential side of the lead screw 902. A rotating groove 905 is opened on the inner top wall of the adjusting groove 901. The rotating groove 905 rotates within the anti-slip rotating block 904.

[0031] For further details, please refer to Figure 4 Two limiting rods 906 are fixedly connected between the side walls of the adjusting groove 901, and the screw nut 903 is slidably connected to the circumferential side of the two limiting rods 906.

[0032] In this embodiment, the lead screw nut 903 moves continuously on the surface of the limiting rod 906, which can improve the movement stability of the lead screw nut 903, thereby improving the movement stability of the mounting slider 6.

[0033] For further details, please refer to Figure 1 Two slide rods 8 are fixedly connected between the side walls of the mounting slider 6, and the mounting slider 6 is slidably connected to the circumferential side of the two slide rods 8.

[0034] In this embodiment, the mounting slider 6 slides on the circumferential side of the slide bar 8, which can improve the movement stability of the mounting slider 6.

[0035] For further details, please refer to Figure 2 A T-shaped pull rod 10 is provided above the threaded column 2, and the lower end of the T-shaped pull rod 10 moves through the inner top wall of the threaded column 2 and is fixed to the anti-detachment block 11.

[0036] In this embodiment, the T-shaped pull rod 10 can pull the anti-detachment block 11 upward and press the circular locking block 15, so that the circular locking block 15 is collected in the rectangular groove 12. Pulling the T-shaped pull rod 10 upward can disengage the circular locking block 15 from the connecting nut 3, thereby separating the connecting nut 3 from the threaded post 2.

[0037] The implementation principle of the above embodiment is as follows: the connecting nut 3 is threaded onto the surface of the threaded post 2. When the connecting nut 3 cannot be rotated, the circular locking block 15 is contracted into the rectangular groove 12 by the force of the threaded post 2, pushing the anti-disengagement block 11 downward. When the locking spring 13 reaches the groove of the connecting nut 3, the locking spring 13 recovers due to its own elasticity, and pushes the circular locking block 15 into the connecting nut 3, thereby realizing the insertion of the circular locking block 15 into the connecting nut 3, preventing the connecting nut 3 from slipping after long-term use, which would affect the tightness of the connection.
