Description

Door lock Internal handle antitheft structure
Technical field
The utility model relates to the structure of safe-guard door lock, especially the Internal handle antitheft structure of door lock.
Background technology
The Mechanical theft-proof door lock the most generally used is at present after taking slow-witted tongue (theft-proof bolt) out of outdoors by key turns, people in door wants to go out and unblanks also must to rotate indentation with key and stay tongue and could open the door, and such door lock can not realize in case of emergency opening rapidly.In order to ensure in emergency circumstances opening rapidly, safety exit, on household security door, particularly electronic safety lock, all adopts band escaping function theftproof lock substantially, and this theftproof lock can realize locking soon and opening soon.Fast lock is exactly upwards carrying outer handle outdoors after resident family gos out, and lock body just can be made to stay tongue and stretch out and lock, and does not need same common lock equally to want counter-clockwise screw key to lock; Meanwhile, door Internal handle also can on put on lock.Open soon be exactly user in door, press down handle, just can simultaneously indentation (unlatchings) latch bolt, stay tongue and safety tongue, open security door fast, realize the function of safety exit, lock body mechanical lock core in door with this function is locked.But the rear handle of safe-guard door lock can press down the feature of directly opening the door and there is huge potential safety hazard.Existing a kind of means stealing enabling, first disclose the opal on door inwards, then stretch into flexible connecting rod from opal, press down after pushing up Internal handle, can open the door; If without opal on door, also can stretch into connecting rod from the crack between a door and its frame below door, drop-downly after being with Internal handle can to open the door.
For solving above-mentioned potential safety hazard, current some electronic anti-theft door locks on the market, circuit is then utilized to solve this problem, general way is: on the rear board of lock, fill an electronic key, after pressing this key, the control circuit driving clutch action of lock body inside makes handle and the occlusion of square core, then handle hand just can be unblanked, otherwise clutch can not action, handle dallies.This method has two shortcomings: the first uses inconvenient, and user opens the door will do two actions, pushes button before this, swing handle again, bothers than traditional door-opening mode; It two is there is larger potential safety hazard, open the door away indoor and will rely on control circui clutch operating, and once fire occurs or other reason causes fault, then people can be caused from opening the door away within doors, easily cause serious security incident, this is quite serious design defect.
Summary of the invention
The purpose of this utility model improves significant deficiency of the prior art, provides a kind of door lock Internal handle antitheft structure, can strengthen anti-theft feature while guaranteeing to open rapidly.
The technical solution adopted in the utility model is, handle cover after being provided with, square core return spring, square core rotatable lamella, push pipe, Fang Xin, two handle pins, handle button after handle and after; Rear handle cover central authorities establish side's core via hole that Fang Xin is extended there through, and rear handle cover rear end is provided with handle cover build-in block, handle cover capel, handle cover slot, return spring locating hole A, is provided with handle cover pin hole in the middle part of rear handle cover; The side's core rotatable lamella center side of being provided with core embedding Kong Yufang core build-in, square core rotatable lamella front end is provided with rotatable lamella engaging tenon and can engages with handle cover slot, and be also provided with return spring locating hole B, square core rotatable lamella rear end is provided with rotatable lamella reset tenon; Core return spring two ends, side are provided with reference column and insert in return spring locating hole A and return spring locating hole B respectively; Rear handle one end is provided with the first handle chamber and the second handle chamber, is provided with handle cover embedded slot, handle pin hole and reset baffle block in the first handle chamber, and be provided with button spacing ring and guiding rib in the second handle chamber, guiding rib end is provided with the first guiding surface; Rear handle button one end is provided with button latch stop ring and gathering sill, and gathering sill one end is provided with the second guiding surface; Rear handle button and item pipe embed in the second handle chamber, and rear handle cover and square core rotatable lamella embed in the first handle chamber; Handle cover build-in block embeds in handle cover embedded slot, and handle pin is each passed through handle pin hole and handle cover pin hole.
When pressing rear handle button, under the effect of guiding rib and gathering sill, button latch stop ring compresses push pipe and moves down, after the elastic force of the side's of overcoming core return spring, snapped in handle cover slot by the rotatable lamella of square core rotatable lamella engaging tenon, make rear handle cover and square core rotatable lamella be in fastening state, after now rotating, handle can drive Fang Xin to rotate, thus realize opening door lock, it is quite convenient to open.Not according to rear handle button, rear handle cover and square core rotatable lamella separate by side's core return spring, rear handle cover and square core rotatable lamella is made to be in released state, rear handle is in anti-theft modes, after now rotating, handle can not drive Fang Xin to rotate, namely after, handle idle running, cannot unblank, the anti-theft feature of handle after realizing.
Press rear handle button or dextrorotation knob 90 ゜ left, guiding rib and gathering sill is made to form dislocation, guiding rib presses on locking button latch stop ring realized to handle button, rear handle cover and square core rotatable lamella are in fastening state all the time, as long as press down rear handle just can unblank, this state is rear handle button locking pattern.Want the locking mode untiing rear handle button, only need pin rear handle button reversely rotates 90 ゜, and rear handle button can be made to eject, the anti-theft feature of handle after recovering.
The beneficial effects of the utility model are, pass through such scheme, when after achieving pressing, handle button opens the door, completely according to the physilogical characteristics of human body and the custom of action, staff after holding while handle thumb just in time press after handle button, press down rear handle gently, door opening action accomplish without any letup, rear handle is put on lock without the need to pressing rear handle button, with daily habits without indisposed sense.After completing enabling, rear handle button automatic spring, effectively enhances the theftproof performance of door lock; Rear handle button can also carry out locking or unlocking according to user's request, enhances the ease for use of door lock.
