The utility model compared with prior art, has the following advantages that：

1st, the utility model exquisite composition, all actions are by handle swing handle drive gear, handle drive gear Drive the motion of miscellaneous part, whether key inserts in lock core the simply rotation of control lock core control shaft, avoids the occurrence of key and breaks Failure in lock core；

2nd, the transmission device includes drive block A and drive block B, and the drive block A is slidably connected on bottom plate, drive block A one end is stretched out from pull bar bottom, and what the axis that the end is provided with rotating shaft be located at vertical plane presses bearing, presses bearing and rack dragging Promotion inclined-plane on block is in contact；Drive block B is slidably connected on drive block A the other end, is set between drive block B and drive block A There is pulling spring, drive block B is provided with baffle plate, and unlocking slide plate is provided with driving projection, and driving is raised to move positioned at baffle plate to pull bar This side, when 90 ° of the non-rotate counterclockwise of middle part moving block presses clamping block so that unlocking slide plate separates with lower slide plate, clamping block During in initial position, unlocking slide plate and lower slide plate clamping, unlocking slide plate and lower slide plate synchronization action, and when lock core does not insert key （When not inserting key, lock core control gear can not rotate, and lower slide plate can not slide due to being engaged with lock core control gear）, unlock Slide plate can not slide simultaneously with lower slide plate, and the cylinder pushing block on unlocking slide plate will not press drag strut, so as to rack dragging block Can not pushing drawing rod motion, now, when rotating clockwise handle by force, handle drive gear band carry-over bar dragging block, rack drags Promotion slope driving on motion block presses bearing and drive block A is moved, and drive block A is moved and drive block B can not be moved, now Only compression pulls spring, the parts without destroying lock body, ensure that the life-span of lock body to a certain extent；

3rd, drag strut is connected with pull bar, the tractor hole set by rack dragging block is not extended on the top of drag strut In, rack dragging block can not drive pull bar movement that dead bolt is retracted into lock body；

4th, lock core device includes locked slide plate, and the locked stuck point of locked slide plate and end inserts in the locked neck set by pull bar Interior, pull bar can not drive dead bolt to move, and further ensure that the security of lock body；

5th, when key inserts in handle counterclockwise in lock core, lock push rod and press to lock and stir projection, it is clockwise to lock driver plate Rotate, promote slope driving to lock fixture block and move right so that the downside that stuck point inserts in locked stuck point is locked, locked stuck point is anti- Lock in the locked neck on pull bar, further ensure that the security of lock body；In addition, when being not inserted into key, i.e., lock core controls Axle and when locking driver plate and can not rotate, it is slidably connected to due to locking push rod and locks support, lock and stage clip is cased with push rod, lock The top of push rod is provided with protruding circular ring, between stage clip is located at protruding circular ring and locks support, now carries handle upwards, only presses Contractive pressure spring, door will not be locked by mistake, also will not destroy lock body due to carrying handle upwards by force, further ensure lock body Life-span；

6th, when user is in door, rotation middle part knob, 90 ° of middle part moving block rotate counterclockwise, presses clamping block and cause Unlocking slide plate separates with lower slide plate, and unlocking slide plate need not be synchronized with the movement with lower slide plate, now, rotates clockwise handle and causes handle Drive gear is rotated, handle drive gear band carry-over bar dragging block, and the promotion slope driving on rack dragging block, which presses bearing, to be made Drive block A motions are obtained, drive block A is by pulling spring drive block B to move, so as to drive unlocking slide plate to move upwards, circle Post pushing block presses drag strut, and the top surface of the top stretching pull bar of drag strut is located in tow tank, and slide plate of unlocking drives and opened Lock travelling gear to rotate, unlocking travelling gear drives locked slide plate to move downward so that locked stuck point exits locked on pull bar Neck（Meanwhile the spacing preiection in the middle part of locked slide plate promotes middle knob to reset）, now, rack dragging block is incited somebody to action to left movement Drive pull bar to left movement, unlocked so as to drive dead bolt motion to realize, avoid directly pushing handle unlocking, that is, avoid opal from opening Lock, improve the security of lock body；

7th, for user when outdoors, key inserts in lock core, rotates clockwise handle and handle drive gear is rotated, handle Drive gear band carry-over bar dragging block motion, the promotion slope driving that rack is dragged on block press bearing and drive block A are moved, Drive block A is by pulling spring drive block B to move, so as to drive unlocking slide plate to move upwards, because unlocking slide plate is with Slide plate is by clamping block clamping, unlocking slide plate and lower slide plate synchronization action, and the cylinder pushing block on unlocking slide plate presses drag strut, The top surface that pull bar is stretched out on the top of drag strut is located in tow tank, and lower slide plate drives lock core control pinion rotation, lock core control Gear processed, which drives, to be locked slide plate and moves downward, and is locked fixture block and is followed and lock slide plate and move downward, the slipper push in supporting plate is anti- The fixture block of locking of pintle hook lock block resets inclined-plane so that locking fixture block reset, locks stuck point and is retracted on the inside of locked stuck point, and releasing is locked, Unlocking slide plate drives unlocking travelling gear to rotate, and unlocking travelling gear drives locked slide plate to move downward so that locked stuck point moves back The locked neck gone out on pull bar, now, rack dragging block to left movement by drive pull bar to left movement, so as to drive dead bolt Motion, which is realized, to be unlocked, and while unlocking, dead bolt bottom plate presses clamping block pushing plate so that clamping block pushing plate promote clamping block to Left movement, unlocking slide plate need not be synchronized with the movement with the no longer clamping of lower slide plate, and now, lower slide plate makes because the pulling of spring resets Obtain key to automatically reset, be easy to user to extract key, user opens the lock with the key efficient and convenient outside；

8th, it is rotatably connected to positioned at the return projection set by locked slide plate in the supporting plate of this side of pull bar locked The rotation-limited block of slide plate, bottom knob is fixedly connected with the rotation-limited block, the bottom knob is push type knob；When Indoor pressing simultaneously rotates clockwise bottom knob so that rotation-limited block rotates clockwise 90 ° so that rotation-limited block, which props up, to be returned Projection is returned, locked slide plate can not move to the direction away from pull bar, i.e., locked stuck point can not exit locked neck, so that drawing Bar can not move, and lock door from internally, ensure the security of lock body；Bottom knob is pressing rotary type knob, is prevented Child does not lock oneself within doors；

9th, when handle rotates counterclockwise, pick-proof drive rod pulls pick-proof driving raised so that and pick-proof driving plate is slided, so as to It is vertical with dead bolt bottom that pick-proof driven by rotary disc pick-proof portion turns to pick-proof portion together, prevents that dead bolt from being prized back, increases the peace of lock body Quan Xing；

10th, at closing time, the touch pole on dead bolt is pressed by doorframe, and touch pole presses the vertical edge of dead bolt buckle so that fastening Raised B unclamps the raised A of fastening and causes dead bolt to eject the state that keeps Locked, i.e., the dead bolt on dead bolt bottom plate all ejects, and avoids making User forget to lock the occurrence of, whole dead bolts is locked in automatic spring at closing time, it is ensured that security.

The utility model is described further with reference to the accompanying drawings and examples.
