Detailed ways

The embodiments of the present invention will be described in further detail below. Contents that are not described in detail in the embodiments of the present invention belong to the prior art known to those skilled in the art.

The preferred embodiment of the bicycle front wheel lifting device with trigger mechanism of the present invention is:

It includes a lifting frame body, the lifting frame body includes a column and a beam, the column is provided with a guide rail, the beam is installed on the guide rail, and a beam lifting spring is arranged between the beam and the column;

A trigger mechanism is provided between the front end of the bottom surface of the beam and the upright column, the rear end of the upper surface of the beam is provided with a front wheel bracket, the trigger mechanism is connected with the beam and forms a moving pair, the front wheel The bracket is connected with the beam through the connecting shaft of the front wheel bracket and forms a rotating pair;

The bottom of the front wheel bracket is provided with a crank, and the lower end of the crank passes through the beam and is connected with the trigger mechanism through a connecting rod, and the connecting rod is simultaneously connected to a stretching and rebounding device; the stretching When the rebound device is reset, the trigger mechanism is located at the front end and is stuck on the column; when the connecting rod pulls the trigger mechanism to the rear end position, the trigger mechanism is separated from the column;

The bottom surface of the beam is provided with a stop mechanism, the stop mechanism is connected with the beam through the stop mechanism connecting shaft and forms a rotating pair, and the upper end of the stop mechanism passes through the beam and is connected with the front beam. Matching hooks and grooves are arranged between the wheel brackets.

The triggering mechanism is connected with the mounting hole below the lifting device through an anti-loosening screw, and a sliding groove is formed at the bottom of the triggering mechanism to form a horizontal moving pair between the triggering mechanism and the anti-loosening screw.

A spherical pair is installed at the lower end of the stop mechanism.

In the bicycle front wheel lifting device with a trigger mechanism of the present invention, the trigger mechanism is connected with the lifting device through an anti-loosening screw to form a moving pair. The front wheel bracket is connected with the main body of the lifting frame through the connecting shaft of the front wheel bracket and forms a rotating pair with the main body of the lifting frame.
