[0022] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0023] This utility model provides, for example Figures 1-5 The illustrated vehicle quick-release bracket includes a connecting bracket 11. The connecting bracket 11 is threadedly connected to a lower connecting block 2 via a lower connecting bolt 10. A locking assembly is rotatably connected to the bottom end of the connecting bracket 11. An upper connecting block 1 is slidably mounted on the top end of the lower connecting block 2. The upper connecting block 1 has a limiting groove 103. A limiting bolt 4 extending into the limiting groove 103 is threadedly connected to one side of the lower connecting block 2. A quick-release wrench 5 is detachably mounted on the outside of the limiting bolt 4 to rotate it. When the limiting bolt 4 separates from the limiting groove 103, the upper connecting block 1 and the lower connecting block 2 form a sliding connection. The limiting bolt 4 has multiple latches that mate with the quick-release wrench 5. The limiting bolt 4 and the quick-release wrench 5 can be non-standard parts to increase the difficulty of theft after the product is sold.

[0024] The upper connecting block 1 has a slider 101 at its bottom end, and a limiting groove 103 is formed on the side wall of the slider 101. The lower connecting block 2 has a sliding groove 201 at its top end that matches the slider 101, and one end of the limiting bolt 4 extends into the inner side of the sliding groove 201. When the limiting bolt 4 is loosened, the end face of the limiting bolt 4 can move away from the outside of the slider 101, ensuring that the slider 101 will not interfere with the limiting bolt 4 during rotation.

[0025] The bottom end of the slider 101 is provided with multiple guide blocks 102, and the top end of the slide groove 201 is provided with a guide groove 203 for the guide blocks 102 to slide. The guide groove 203 can be a through groove or a one-way groove. When the guide groove 203 is a one-way groove, when one end of the guide block 102 is in contact with the side wall of the guide groove 203, the position of the limiting groove 103 corresponds to the position of the limiting bolt 4, reducing the difficulty of aligning the upper connecting block 1 and the lower connecting block 2.

[0026] The bottom end of the slider 101 has a countersunk hole 104, and an upper connecting bolt 3 is installed inside the countersunk hole 104. The threaded end of the upper connecting bolt 3 extends to the outside of the upper connecting block 1. The upper connecting bolt 3 is used to connect with the external structure, which facilitates the overall installation of the device and reduces the difficulty of installation. The extreme position of the top of the lower connecting bolt 10 is located at the bottom end of the guide groove 203 to avoid interference with the sliding of the upper connecting block 1.

[0027] The lower connecting block 2 has a pin hole 202 at its top. One end of the pin hole 202 communicates with the bolt hole of the limiting bolt 4. The end of the limiting bolt 4 near the pin hole 202 is provided with a light shaft. A limiting pin 13 is slidably disposed inside the pin hole 202 to prevent the limiting bolt 4 from loosening. When the limiting bolt 4 moves to the preset position, the side wall of the limiting pin 13 will move from the light shaft to the threaded end, and the limiting pin 13 will press against the thread of the limiting bolt 4, thereby stopping the limiting bolt 4 from rotating and achieving the purpose of preventing the limiting bolt 4 from loosening.

[0028] The locking assembly includes a rotating connecting block 9, an upper locking block 6, and a lower locking block 7. The rotating connecting block 9 is rotatably connected to the connecting bracket 11 via a rotating shaft 12. The upper locking block 6 is rotatably connected to the bottom end of the rotating connecting block 9. The upper locking block 6 and the lower locking block 7 are hinged together. One end of the upper locking block 6 and the lower locking block 7 is threadedly connected to the locking bolt 8. The rotating connecting block 9 has a hole inside for receiving the locking bolt 8, allowing the locking bolt 8 to have a longer length, expanding the adjustment range of the locking force, and helping to prevent the locking bolt 8 from loosening. The hinge between the upper locking block 6 and the lower locking block 7 is eccentrically set, which can reduce the overall width of the device. The rotating shaft 12 is composed of a bolt and nut. By locking the rotating shaft 12, the rotation angle of the locking assembly can be fixed, improving the range of motion of the bracket.

[0029] The upper locking block 6 and the lower locking block 7 are fitted with open bushings on their inner sides. There may be one or more open bushings, which are used to increase the friction on the connecting shaft. The setting of open bushings can control the locking force on the connecting shaft through the locking bolt 8, reducing the difficulty of installing and disassembling the connecting shaft. Setting multiple open bushings can accommodate connecting shafts of different diameters, thus improving the adaptability.

[0030] This invention achieves the locking of the upper connecting block 1 and the lower connecting block 2 by extending the limiting bolt 4 into the limiting groove 103. The two are locked together to prevent separation. The slider 101 and the sliding groove 201 restrict the degree of freedom of the upper connecting block 1. By rotating the quick-release wrench 5, the limiting bolt 4 is moved away from the limiting groove 103, and the upper connecting block 1 can slide along the guide groove 203 to separate the two, thereby achieving quick disassembly and reducing the difficulty of disassembly and assembly. The setting of the limiting pin 13 and the optical axis of the limiting bolt 4 can prevent the limiting bolt 4 from falling off as it rotates outward, ensuring the reliability of the connection and avoiding locking failure due to the loosening of the limiting bolt 4.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
