Description

Technical Field

[0001] The utility model relates to an additional device for an automobile, in particular to a ball head connecting clamp for a vehicle-mounted hanger. Background Art

[0002] The vehicle-mounted rack is a device installed at the rear of the car for transporting bicycles, motorcycles and other items to solve the problem that bicycles and other items are inconvenient to carry with the car due to their large size. The common way to fix the vehicle-mounted rack to the car is: the connecting device on the vehicle-mounted rack is fixed to the ball head connector at the rear of the car. The existing connecting devices are either integrated with the rear bicycle rack, with one vehicle-mounted rack equipped with one connecting device, which makes it impossible to disassemble and assemble, and the cost is high; or there are problems such as inconvenient operation, cumbersome connection process, complex structure and poor stability.

[0003] For example, the Chinese utility model patent "Ball head fixing clamp for vehicle-mounted bracket" with patent number ZL202221361828.6 (authorization notification number CN217969388U) discloses such a structure, including a first fixing seat and a second fixing seat. When the first fixing seat and the second fixing seat are closed, the accommodating grooves thereon are combined to form a mounting hole for fixing the automobile ball head connector, and also include a locking structure for locking the first fixing seat and the second fixing seat in the closed position; the locking structure includes a locking rod, the inner end of the locking rod has a threaded column portion, the outer end of the locking rod has a head, the inner end surface of the first fixing seat is provided with a threaded hole, and the second fixing seat is provided with a through hole for the locking rod to movably pass through. The locking rod is passed through the through hole and can rotate around its own axis. When the first fixing seat and the second fixing seat are closed, the threaded column portion of the locking rod passing through the through hole is threadedly connected to the threaded hole, and the head is pressed tightly against the side of the second fixing seat.

[0004] Since the first fixing seat and the second fixing seat are locked to each other by a locking rod after being closed, the locking rod with a thread passes through the through hole of the second fixing seat and is threadedly connected with the threaded hole of the first fixing seat to achieve fixation. In order to make the first fixing seat and the second fixing seat lock tighter, it is often necessary to use an auxiliary tool to drive the locking rod to rotate many circles before fixation can be achieved, and quick installation or quick disassembly cannot be achieved. If the auxiliary tool is lost, installation or disassembly cannot be performed, resulting in embarrassing situations.

[0005] Therefore, how to provide a fixing method for quickly fixing the connecting device of the vehicle-mounted hanger on the ball head without the aid of auxiliary tools is a problem that technical personnel in this field need to solve urgently. Utility Model Content
