The utility model provides a motorcycle fuel tank cap installs the fuel filler department at motorcycle fuel tank. As shown in fig. 1 to 3, in a preferred embodiment of the present invention, the tank cap includes a stationary barrel 20 fixedly coupled to the tank 10 and having both ends opened, a rotary barrel 30 threadedly coupled to the stationary barrel 20 and having both ends opened, and a shutter 40 rotatably coupled to the stationary barrel 20 and opening or closing the oil filler hole 11. In the present embodiment, the fixed cylinder 20 and the rotary cylinder 30 are made of plastic, the lower end of the fixed cylinder 20 extends radially outward to form a mounting seat 21, for example, the mounting seat 21 is formed by integral injection molding, and a mounting hole (not shown) for connecting with the fuel tank 10 is formed in the mounting seat 21, that is, the mounting seat 21 is in a flange structure. The upper end surface of the baffle 40 is rotatably connected with a pull rod 50 through a pin shaft or a hinge, the upper end of the pull rod 50 is rotatably connected with the inner wall of the rotary cylinder 30, and the pull rod 50 can circumferentially rotate on the inner wall of the rotary cylinder 30, for example, the pull rod 50 is connected with the left side of the inner wall of the rotary cylinder 30.

When in use, the fixing cylinder 20 is fixedly connected with the motorcycle oil tank 10 through the mounting hole of the mounting seat 21 by a bolt, so that the oil tank cover is arranged at the oil filling port 11 of the motorcycle oil tank 10. As shown in fig. 2, the flapper 40 covers the filler port 11 in a normal state, and closes the filler port 11. As can be seen from fig. 3, when oil needs to be added, people rotate the rotary cylinder 30, the rotary cylinder 30 moves upwards spirally, and the pull rod 50 can rotate circumferentially on the inner wall of the rotary cylinder 30, so that the upper end of the pull rod 50 moves upwards and rotates when the rotary cylinder 30 moves upwards spirally, and the upper end of the pull rod is still located on the left side; the movement of the lever 50 rotates the flapper 40 counterclockwise (i.e., upward as viewed in fig. 2) to open the filler port 11, and oil can be supplied to the oil tank 10 after the filler port 11 is opened. After refueling, one rotates the rotary cylinder 30 in the reverse direction to rotate the flapper 40 clockwise (i.e., downward as viewed in fig. 3) until the fuel filler port 11 is completely closed. It should be noted that, during the opening of the oil filler 11, the rotary cylinder 30 is spirally moved upward on the fixed cylinder 20 without being separated from the fixed cylinder 20.

By adopting the technical scheme, in the refueling process, people can open the refueling port 11 without taking down any part in the fuel tank cover, so that the fuel tank cover cannot be lost in the refueling process. When the oil filling port 11 is opened or closed, only the rotary cylinder 30 needs to be rotated, so that the operation is simple and the use is convenient; and the rotating cylinder 30 is in threaded connection with the fixed cylinder 20, so that the self-locking effect is good.

As shown in fig. 1, the specific connection manner of the pull rod 50 and the rotary cylinder 30 is as follows: the inner wall of the lower part of the rotary cylinder 30 is provided with a circumferential annular groove 31, the upper end of the pull rod 50 is rotatably connected with a slide block 61 through a pin shaft, the slide block 61 is provided with a slide head 61 matched with the annular groove 31, and the slide head 61 is clamped in the annular groove 31 and can slide in the annular groove 31 in the circumferential direction. In the process that the rotating cylinder 30 is rotated to make the rotating cylinder 30 move upwards or downwards in a spiral manner, the sliding head 61 of the sliding block 61 slides in the annular groove 31 of the rotating cylinder 30, so that the sliding block 61 cannot move along the circumferential direction of the rotating cylinder 30, and the upper end of the pull rod 50 is always positioned on the left side in fig. 1-3.

As shown in fig. 3, after the oil filling opening 11 of the oil tank 10 is opened, the baffle 40 abuts against the slider 61, so that one cannot rotate the rotary cylinder 30 any more, and the rotary cylinder 30 is prevented from being separated from the fixed cylinder 20, i.e., the slider 61 can also serve as a stopper for the stop position of the baffle 40. It should be noted that when the length of the flapper 40 is longer and the oil filler 11 is opened, the flapper 40 may also abut against the inner wall of the spin basket 30 so that one cannot continue to rotate the spin basket 30.

In another preferred embodiment of the present invention, in a normal state, the middle lower portion of the rotary cylinder 30 is located in the fixed cylinder 20, and the upper end of the rotary cylinder 30 extends radially outward to form a complete circle of the rotary portion 32 located above the fixed cylinder 20, such as an integral injection molding, and the rotary portion 32 has an anti-slip groove. The specific thread connection mode of the rotary cylinder 30 and the fixed cylinder 20 is as follows: the inner wall of the fixed cylinder 20 is provided with an internal thread, and the outer wall of the middle lower part of the rotary cylinder 30 is provided with an external thread matched with the internal thread.

As shown in fig. 1 to 3, in another preferred embodiment of the present invention, a sealing ring 41 capable of sealing the oil filling opening 11 is fixed to the lower end surface of the baffle plate 40, the sealing ring 41 may be a flat gasket or an O-ring, such as a rubber ring, and the sealing ring 41 is clamped or bonded to the lower end surface of the baffle plate 40.

As shown in fig. 1, in another preferred embodiment of the present invention, the left side of the lower end of the fixed cylinder 20 has a connecting portion 22 extending radially inward, such as an integral injection molding, and the left end of the baffle 40 is rotatably connected to the connecting portion 22 of the fixed cylinder 20 by a pin. When the oil filling port 11 of the oil tank 10 is in a closed state, the distance from the connection point a of the connection portion 22 and the baffle 40 to the inner wall of the fixed cylinder 20 is greater than the distance from the connection point B of the pull rod 50 and the rotary cylinder 30 to the inner wall of the fixed cylinder 20. Thus, as shown in fig. 3, in the process of opening the fuel filler 11, the flapper 40 rotates by an angle greater than 90 °, so that the fuel filler 11 can be completely opened, facilitating the refueling.

In the description herein, reference to the description of the terms "preferred embodiment," "one embodiment," "some embodiments," "an example," "a specific example" or "some examples" or the like means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the invention.
