In the figure: the lock comprises a lock shell 1, a lock liner 2, a lifting groove 201, a supporting portion 202, a fixing groove 203, a blade assembly 3, a locking piece 4, an object placing groove 401, an extending portion 402, a locking bead 5, a return spring 6 and a key 7.
Detailed Description
The following description of the embodiments refers to the accompanying drawings for illustrating the specific embodiments in which the invention may be practiced. Directional phrases used herein, such as, for example, upper, lower, front, rear, left, right, inner, outer, lateral, and the like, refer only to the accompanying drawings. Accordingly, the directional terms used are used for explanation and understanding of the present invention, and are not used for limiting the present invention. In the drawings, elements having similar structures are denoted by the same reference numerals.
The technical solution and the advantages of the present invention will be more clear and clear by further describing the embodiments of the present invention with reference to the accompanying drawings.
Referring to the drawings 1 to 4, the utility model discloses a lock shell 1 and lock courage 2 mutually support are equipped with blade subassembly 3 and locking plate 4, its characterized in that in the lock courage 2: a cylindrical locking bead 5 is arranged above the locking sheet 4, and the locking bead 5 is used for instantly pressing the locking sheet 4 inwards along with the change of the inner cavity wall of the lock shell 1 when the lock cylinder 2 rotates;
the diameter of the locking bead 5 is larger than or equal to the thickness of the locking piece 4;
the highest point of the locking bead 5 is larger than the highest point of the locking flap 4.
Further, the length of the locking bead 5 is smaller than that of the locking piece 4, an article placing groove 401 for placing the locking bead 5 is arranged on the locking piece 4, and the article placing groove 401 is located in the center of the top of the locking piece 4.
Further, the length of the locking bead 5 is less than or equal to the length of the locking flap 4.
Furthermore, the ends of the left and right ends of the locking plate 4 are provided with extending portions 402, and the height of the extending portions 402 is smaller than the height of the middle of the locking plate 4.
