[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.
[0022] Reference Figures 1-4 A fixed connection structure for a car front grille trim strip includes a front grille body 1 and a mounting bracket 2. The mounting bracket 2 has a mounting groove 3 on its top, and the mounting bracket 2 is located within the mounting groove 3. Two first sliding grooves 6 are formed on both sides of the mounting bracket 2. A lever 7 is slidably connected within the two first sliding grooves 6. The first sliding grooves 6 guide the lever 7 and limit the distance the lever 7 moves, thus enabling the lever 7 to move stably. A wedge block 15 is fixed to the bottom end of the lever 7 by bolts, and the wedge block 15 is slidably connected to the first sliding groove 6. A first spring 16 is welded to one end of the wedge block 15 and is fixed to the mounting bracket 2. Two second slots 14 are formed on both sides of the front grille body 1, and the second slots 14 engage with the wedge block 15. Two second sliding grooves 8 are formed on both sides of the mounting bracket 2. A bracket 17 is slidably connected in the groove 8, and the bracket 17 is in contact with the lever 7. A second spring 18 is welded to one side of the bracket 17, and the second spring 18 is fixed to the mounting bracket 2. Two blocking components that restrict the movement of the bracket 17 are provided on both sides of the mounting bracket 2. When the bracket 17 is pushed, it moves along the second groove 8, and the second spring 18 retracts. The blocking components keep the position of the moved bracket 17 fixed. At the same time, the bracket 17 moves and separates from the lever 7. At this time, the lever 7 is no longer restricted. The operator pushes the lever 7, so that the wedge block 15 moves out of the second slot 14, and the first spring 16 retracts. When the horizontal position of the lever 7 passes the bracket 17, it separates the blocking components from the bracket 17. At this time, the second spring 18 rebounds and extends, so that the bracket 17 resets and blocks the lever 7. Then the operator can directly separate the front grille body 1 from the mounting bracket 2.
[0023] In this invention, it should be noted that the blocking assembly includes a cylinder 10, which is rotatably connected to one side of the mounting bracket 2. A connecting rod 12 is rotatably connected to the outer side of the cylinder 10. A protrusion 13 is welded to one end of the connecting rod 12, and the protrusion 13 contacts the bracket 17. A torsion spring 11 is sleeved on one end of the cylinder 10. When the bracket 17 moves and the second spring 18 contracts, the bottom of the bracket 17 compresses the arc surface of the protrusion 13, causing the connecting rod 12 to rotate and the torsion spring 11 to deform until the top of the bracket 17 contacts the protrusion 13. At this time, the torsion spring 11 rebounds and resets, and the protrusion 13 locks the bracket 17, thereby keeping the position of the moved bracket 17 fixed. The two ends of the torsion spring 11 are respectively fixed to the cylinder 10 and the connecting rod 12. The blocking component restricts the position of the card holder 17, facilitating subsequent operations. Two first slots 5 are provided at both ends of the front grille body 1. Limiting blocks 4 are fixed to both ends of the mounting bracket 2 with bolts. The first slots 5 engage with the corresponding limiting blocks 4. The cooperation between the limiting blocks 4 and the first slots 5 facilitates the positioning and installation of the front grille body 1 and the mounting bracket 2, avoiding time-consuming and laborious repeated adjustments to the connection position. Fixing blocks 9 are fixed to the top of both sides of the mounting bracket 2 with bolts, and the fixing blocks 9 are in contact with the connecting rod 12. The fixing blocks 9 can limit the rotation distance of the connecting rod 12 to prevent excessive movement of the connecting rod 12. The contact surface between the protrusion 13 and the card holder 17 is an arc surface.
[0024] The working principle of this utility model is as follows: When the device needs to be disassembled, first push the bracket 17 to move it along the second slide groove 8, and the second spring 18 retracts. At this time, the bottom of the bracket 17 squeezes the protrusion 13, causing the connecting rod 12 to rotate and the torsion spring 11 to deform until the top of the bracket 17 contacts the protrusion 13. At this time, the torsion spring 11 rebounds and resets, thus fixing the position of the moved bracket 17. At the same time, the bracket 17 moves and separates from the lever 7. At this time, the lever 7 is no longer restricted. The operator pushes the lever 7 to move it along the first slide groove 6 until the wedge block 15 moves out of the second slot 14 and the first spring 16 retracts. When the horizontal position of the lever 7 passes the bracket 17, rotate the connecting rod 12 to separate the protrusion 13 from the bracket 17. At this time, the second spring 18 rebounds and extends, causing the bracket 17 to reset and block the lever 7. Then the operator can directly separate the front grille body 1 from the mounting bracket 2.
