Detailed Description

Referring to fig. 1 to 3, the detailed structure of the preferred embodiment of the present invention is shown, which includes a lock barrel 10, a rotating shaft 20, a dust cover 30, a positioning assembly 40 and a spring 50.

With further reference to fig. 3-5, the barrel 10 includes an insertion face 11, a key hole 12, a positioning slot 13, and a shaft slot 14; the key hole 12, the positioning groove 13 and the shaft groove 14 are formed on the insertion surface 11, preferably, the key hole 12, the positioning groove 13 and the shaft groove 14 are connected in a straight line, and the positioning groove 13 and the shaft groove 14 are respectively located on two sides of the key hole 12, but the positions and the relative relationship of the three are not limited to the above. In addition, the positioning slot 13 is used in cooperation with the positioning component 40 to limit the rotation of the dust cover 30, but it may not have the positioning slot 13, and the invention is not limited thereto. Further, the shaft groove 14 is provided with a spring 50 to stabilize the rotating shaft 20, but it may be provided without the shaft groove 14.

The spindle 20 is disposed on the key seat 10 and protrudes from the insertion surface 11, and the spindle 20 is perpendicular to the insertion surface 11. Preferably, the rotating shaft 20 is disposed in the shaft groove 14, and the rotating shaft 20 has a ring protrusion 21, and the ring protrusion 21 is convenient for the spring 50 to abut against to stabilize the rotating shaft 20, but it may have no ring protrusion 21, and is not limited thereto.

The dust cap 30 is connected to the spindle 20, and the dust cap 30 can be rotated relative to the barrel 10 by the spindle 20, thereby selectively covering the key hole 12. Preferably, the dust cap 30 can rotate 360 degrees relative to the barrel 10, but the angle at which the dust cap 30 can rotate relative to the barrel 10 is not limited thereto.

The positioning assembly 40 is disposed on the dust cap 30 and can limit the dust cap 30 from rotating relative to the barrel 10. Specifically, the positioning assembly 40 includes two magnets 41, the two magnets 41 are respectively disposed on the dust cap 30 and the barrel 10, and the two magnets 41 can attract each other to thereby limit the rotation of the dust cap 30 relative to the barrel 10. However, the specific structure of the positioning assembly 40 is not limited to two magnets 41, for example, the positioning assembly 40 may be a magnet disposed on one of the dust cover 30 or the barrel 10 and an iron block disposed on the other of the dust cover 30 or the barrel 10, so that the magnet attracts the iron block to thereby limit the rotation of the dust cover 30 relative to the barrel 10.
