The winding wheel 4 rotates, thereby tightly winding the rope 5, thereby moving the sphere 26 upward, whereby the ball 29 and the lock rod 18 move upward, and the arc groove 11 and the arc chamber 13 In the process of moving the two lock rods 18 upward, the ends that are in contact with each other are separated and then contacted again, whereby the two lock rods 18 automatically penetrate and lock the wheels.

It exercised two trapezoidal block 22 to the sides when the downward rod 15 is lowered, after the downward rod 15 is in contact with the position limiting plate 9, downward rod 15 is lowered interlocked position limiting plate 9, the receiving groove 17 push rod When positioned in the same straight line as 8, the push rod 8 enters the storage groove 17 under the action of the push spring 37, restricts the return of the lower push rod 15, and at this time, the electromagnet 35 repels each other with the slide rod 42. As a result, the elevating rod 24 meshes with the rotary gear 25.

When taking out the bicycle, the QR code (registered trademark) 30 is scanned to control the control block 45 to change the magnetism of the electromagnet 35, whereby the electromagnet 35 attracts the slide rod 42 and the elevating rod 24 moves backward. Then, it is separated from the rotary gear, and the sphere 26 is returned under the action of the telescopic spring 28, whereby the lock rod 18 is returned, whereby the wheel is unlocked, and at the same time, the rope 5 and the rope winding wheel 4 are released. At this time, the movement of the elevating rod 24 causes the driven rod 34 to move backward, thereby pulling the chain 20, thereby separating the pushing rod 8 from the storage groove 17, thereby moving the lower pushing rod 15 and the fixing plate. 16 and 16 return, the elevating rod 24 moves upward under the action of the connecting spring 44, and after taking out the bicycle, the control block 45 controls the electromagnet 35 to return, whereby the lock mechanism 51 of the spring It returns under action and the device returns.

The beneficial effect of the present invention is: The device is simple to configure and convenient to operate, the device automatically locks the bicycle after parking, no need to lock by hand, human lock It saves time, saves time, and can be unlocked automatically by scanning the QR code, giving great convenience for people to park their bicycles or lock their bicycles.

The above is merely a specific embodiment of the invention, the scope of protection of the invention is not limited to this, and any changes or replacements that can be conceived without the passage of creative labor are within the scope of protection of the invention. Including inside. Therefore, the scope of protection of the invention should be based on the scope of protection limited to the claims.
