The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.

Example 1:

the lock body of the convenient door lock provided by the embodiment, as shown in fig. 1-3, comprises a lock housing 1, and a bolt assembly 2, a locking dial 6, a locking slider 8 and two bolt dials 5 arranged in the lock housing 1. Two spring bolt dials peach 5 symmetries and leans on in the inside and outside both sides of locking dial peach 6 and rotate relatively and connect, and spring bolt dial peach 5 cooperatees with spring bolt assembly 2 and is connected, and spring bolt dial peach 5 clockwise rotation can drive spring bolt assembly 2 and slide to the right side of lock casing 1, and 5 anticlockwise rotations of inboard spring bolt dial peach can drive locking dial peach 6 anticlockwise rotations. The locking shifting peach 6 is matched and connected with the bolt component 2, and the bolt component 2 slides towards the right side of the lock shell 1 to push the locking shifting peach 6 to rotate clockwise. Locking shift peach 6 and locking slider 8 are connected in coordination, and 6 anticlockwise rotations of locking shift peach can drive locking slider 8 and slide and make locking slider 8 restrict the spring bolt shift peach 5 clockwise rotation in the outside to reach the locked state, and 6 clockwise rotations of locking shift peach can drive locking slider 8 and remove the restriction to the spring bolt shift peach 5 in the outside, in order to reach the unlocked state.

As shown in fig. 3, the lock body of the door lock of the embodiment is connected with the bolt assembly 2 in a matching way by making the bolt dial 5, the bolt dial 5 rotates clockwise to drive the bolt assembly 2 to slide to the right side of the lock shell 1, and the two bolt dial 5 on the inner side and the outer side are respectively connected with the inner handle and the outer handle of the door, so that when the door lock is in an unlocking state, the bolt assembly 2 can be retracted into the lock shell 1 when the inner handle or the outer handle of the door drive the bolt dial 5 to rotate clockwise, and the door can be opened.

Because 5 anticlockwise rotations of inboard spring bolt thumb peach can drive 6 anticlockwise rotations of locking thumb peach, 6 anticlockwise rotations of locking thumb peach can drive locking slider 8 and slide, make locking slider 8 restrict 5 clockwise rotations of spring bolt thumb peach in the outside to reach the locked state. As shown in figure 3, the inner bolt shifting peach 5 is connected with an inner handle of the door, and the locking shifting peach 6 can be controlled by a key to rotate the locking shifting peach 6 outside the door. When the door needs to be locked, a person can rotate the locking picks 6 anticlockwise through a key outside the door to lock, and a person on the inner side of the door can also rotate the handle anticlockwise to lock.

Because spring bolt dial peach 5 clockwise rotation can drive spring bolt subassembly 2 and slide to the right side of lock casing 1, spring bolt subassembly 2 to the right side of lock casing 1 slides and can promotes locking dial peach 6 clockwise rotations, and locking dial peach 6 clockwise rotations can drive locking slider 8 and remove the restriction to the spring bolt dial peach 5 in the outside to reach the unblock state. Therefore, when the door needs to be unlocked, a person on the inner side of the door can unlock the door by clockwise rotation of the door inner handle, and a person on the outer side of the door can unlock the door by clockwise rotation of the key. In addition, when the door is closed after the door is unintentionally locked in the open state, the bolt assembly 2 can slide to the right side of the lock housing 1 under pressure, so that the door lock can be unlocked by the action of closing the door.

In summary, when the lock body of the door lock is used, the door can be locked by rotating the door inside counterclockwise and unlocked or opened by rotating the door inside clockwise; the door can be locked by the counterclockwise rotation of a key on the outer side of the door and unlocked by the clockwise rotation of the key, and the door can be opened by the door handle on the outer side of the door in an unlocked state; in addition, in the door open state, the door can be unlocked directly by the door closing operation when the door is locked. The lock convenient to use of this embodiment can unblock fast in the door inside, is convenient for in time flee under the dangerous condition, and in the door inside to the back of locking, the people in the door also can open the door through the key under the inconvenient situation of unblanking, avoids the emergence of dangerous situation.
