Summary of the invention
At the shortcoming that prior art exists, the purpose of this utility model is to provide a kind of opening and closing structure of rotation lock, makes internal cylinder can arbitrarily rotate after key is extracted out and lock and can not open.
The technical solution of the utility model is: a kind of opening and closing structure of rotation lock, it comprises housing, be arranged at cylindrical shape outer lock core and cylindrical internal cylinder in the described housing rotationally, described internal cylinder is nested in the inside of described outer lock core, described internal cylinder is made up of inner bag core and inner bag cover, between described inner bag core and inner bag cover, be provided with the keyhole parallel with axis direction, above this keyhole, described inner bag in-core is provided with the pellet shot from a slingshot hole of the two line misregistrations arrangement that is communicated with this keyhole along axis direction, one side of described inner bag core also is provided with first groove that connects with two row pellet shot from a slingshot holes, described inner bag is arranged with second groove that connects with first groove, described outer lock core is provided with the 3rd groove that connects with second groove, described inner walls is provided with the 4th groove that connects with the 3rd groove, pellet shot from a slingshot in the described pellet shot from a slingshot hole is provided with breach in a side of corresponding first groove, first groove, second groove, be placed with the profile of tooth locking plate successively in the 3rd groove and the formed space of the 4th groove, circle bar shaped needle roller.
Described inner bag core and inner bag cover are fixed together by staple.
Described pellet shot from a slingshot below is circular, and the top is a flat, and described breach is square.
Head and afterbody at described inner bag core also are respectively equipped with the pellet shot from a slingshot hole that is connected with first groove, and the pellet shot from a slingshot head in this pellet shot from a slingshot hole is conflicted on described profile of tooth locking plate.
The 4th groove is semicircle groove.
Compared with prior art,, therefore extract the back internal cylinder out and can arbitrarily rotate and lock and to open, eliminated certain potential safety hazard at key because there is above-mentioned structure in the utility model.
