Description

Lock improved structure

The utility model relates to an improved structure of a lock, which is provided with a plurality of second bead tips in the bead seat above the lock, and two kinds of unlocking manners are provided by using the pushing portions protruding from the outer edges of the second bead tips, and the second bead tips are provided. The length of the pusher to the same side end of the second bead is the same, and a third unlocking mode is provided to achieve the effect of layer management.

Press, generally in the handling of public affairs storage box, usually will be installed with locks, and the storage box is for multi-person use, so each lock will be set to a different lock body configuration, corresponding to the exclusive key of each lock box lock, Do not allow non-users to accidentally open the compartments belonging to others; however, such compartments must be managed by the administrator, so when the user mistakenly loses or carries the keys, the compartment needs to be updated due to the lock being unusable. Or during maintenance, the administrator can use the spare key to open the compartment, then change the lock or make a new key. Therefore, the manager needs to spare the key corresponding to each lock and carry a large number of spare keys, so the creation of this creation The author proposes a "lock structure" and proposes a new patent application and the announcement is listed as No. M428984. This "lock structure" is a first push that is provided with one end of the second bead to be used to push against the first bead. Abutting surface, and a second pushing surface is disposed on the other end surface away from the first pushing surface, and a pushing portion is protruded from the outer edge of the second bead tip, so that the key can be pushed The second pushing surface or the pushing portion causes the second bead to push the first bead to unlock the lock, so as to unlock the two keys.

However, when a large number of storage boxes are managed by different managers, the keys of each manager cannot unlock the locks of the lock boxes managed by other managers, and also make the general manager It is necessary to reserve a key corresponding to each manager of each lock, and thus carrying a large number of keys of each manager, the same is inconvenient.

Therefore, how to solve the deficiencies and shortcomings of the prior art is the subject of research and development for those involved in this industry.

The main purpose of this creation is to provide two unlocking methods by using the second bead of the lock, and to provide the second bead and the bead seat on the second bead to provide another unlocking manner by positioning. A lock that unlocks the way to provide layered management.

In order to achieve the above purpose, the lock of the present invention mainly comprises a lock case, and a lower bead seat and an upper bead seat are arranged in the lock case, and a lock core is arranged in the lower bead seat and the upper bead seat, and a plurality of locks are arranged in the lower bead seat. a first bead tip, the upper bead seat has a body and a plurality of second bead tips, the surface of the body adjacent to the lower bead seat is provided with an unlocking surface, and the other side surface away from the lower bead seat is provided with an abutting surface, and the body is provided with a plurality of second bead slots extending through the abutting surface and the abutting surface, and the second bead ends are respectively provided with a first pushing surface and a second pushing surface, and protruding on the outer edge of the second bead An abutting portion is formed between the first pushing surface of the second bead and the pushing portion, and an actuating portion is formed between the second pushing surface and the pushing portion, and the unlocking portion of the plurality of second bead ends is The abutting surface side of the body penetrates into the second bead tip groove respectively, and the outer diameter of the pushing portion is larger than the inner diameter of the second bead tip groove, and the lengths of the unlocking portions of the plurality of second bead tips are the same, the plurality of The length of the action portion of the second bead is different, and the length of the unlocking portion of the second bead is the same as the length of the second bead groove of the body.
