Preferably, the lock cylinder is connected with the annular clamping jaw through a steel ball and a spring, the head of the steel ball abuts against the notch in the annular clamping jaw, two ends of the notch are provided with guide inclined planes, the tail of the steel ball is connected with the spring, and the spring is embedded in a counter bore in the lock cylinder.

Through the elastic force of spring, the tight butt of steel ball is on the breach of annular jack catch to realized being connected of annular jack catch and lock core, and when the solenoid valve did not receive signal or when the push rod of solenoid valve did not normally retract, if there is great power to act on rotatory handle this moment, the steel ball can be withdrawed in the inside counter bore of lock core, and annular jack catch breaks away from with the lock core this moment, can prevent through this structure that the inner structure of rotatory handle and lock body is destroyed.

Preferably, the lock tongue is connected with the lock body through a limiting slide rail.

Preferably, the outer surface of the annular clamping jaw is provided with a clamping groove, and the rotating handle is provided with a buckle matched with the clamping groove.

Preferably, the upper surface of the lock body is provided with a character mark.

Preferably, the text is identified as TURN OPEN.

Has the advantages that:

when the rotary handle is rotated, the rotary handle drives the annular clamping jaw, the annular clamping jaw drives the lock cylinder, the two limiting columns on the lower surface of the lock cylinder rotate, and the lock tongue moves inwards in the horizontal direction due to the limiting effect of the L-shaped groove on the upper surface of the lock tongue while rotating, when the lock tongue moves to a designated position, the lock body is opened, and oil can be injected into an oil tank of the motorcycle through the oil injection port.

Detailed Description

In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

As shown in fig. 1-8, a rotary keyless lock protection device for a motorcycle oil filling port comprises a lock body 2, wherein a rotary handle 1, an annular claw 6, a lock cylinder 5, a lock tongue 3 and an electromagnetic valve 4 are arranged inside the lock body 2; rotatory handle 1 be located the top of lock body 2, the bottom of rotatory handle 1 links to each other with annular jack catch 6, the 6 surfaces of annular jack catch are equipped with the draw-in groove, rotatory handle 1 on be equipped with the buckle that matches with the draw-in groove.

The middle part of the annular clamping jaw 6 is connected with a lock cylinder 5, the electromagnetic valve 4 is connected with a wireless key through a controller, a push rod of the electromagnetic valve 4 extends into a counter bore at the head part of the lock tongue 3, and the lock tongue 3 is connected with the lock body 2 through a limiting slide rail.

The upper surface of spring bolt 3 is equipped with L grooves, and the lower surface of lock core 5 even has two spacing posts that are parallel to each other, and two spacing posts all insert in L grooves, and the diameter of spacing post matches with the width in L grooves, and when the lock core rotated, spacing post can drive spring bolt 3 along the horizontal direction inward movement.

As shown in fig. 1, the main body of the latch bolt 3 is disposed in the lock body 2, the head of the latch bolt 3 is engaged with the left structure (motorcycle main frame) of the lock body 2, when the latch bolt 3 is located at the position shown in fig. 1, the oil injection port cannot be opened, and when the latch bolt 3 retracts, the entire oil injection port can be turned to the right side, thereby opening the oil injection port.

The lock core 5 is connected with the annular clamping jaw 6 through a steel ball 7 and a spring 8, the head of the steel ball 7 abuts against the notch in the annular clamping jaw 6, the tail of the steel ball 7 is connected with the spring 8, and the spring 8 is embedded in a counter bore in the lock core 5.
