Abstract

The utility model relates to a door lock, mainly comprising a lock body bottom shell 10, a lock body face cap 1, a shifting rod 2, a locking block 4, a locking block support 6, a rotation tongue 7, a lock body door catch shell 9, and a coil 15. The utility model is characterized in that the locking block support 6 of the rearward of the locking block 4 is provided with a jack; a gear shifting block 11 is arranged in the jack; the gear shifting block 11 is provided with three different gearshifts; the coil 15 adopts the single coil, which forms the closed magnetic coil and increases the attractive force on the shifting rod.

Description

Door lock
Technical field
The utility model relates to a kind of door lock, particularly a kind of commentaries on classics flapper lock of transferring the files.
Background technology
The granted patent that State Intellectual Property Office of the People's Republic of China announces number is that 02272696.9 utility model door lock has adopted and changes tongue and substitute traditional telescopic tongue, and simple in structure, the noise that opens the door is less.Yet if having the people to grasp key is easy to from the external opening door lock, seems that in some occasion the safety confidentiality is not enough, adjustability is not enough.The automatically controlled unlocking apparatus of existing door lock is by being provided with two magnetic coils arranged side by side, and behind the connection power supply, the magnetic coil energising produces magnetic attraction connection poke rod lock is opened.Often after connecting power supply, can hear the sound that institute's poke rod sends, and door is not opened really in the practice.It mainly is to adopt magnetic coil arranged side by side, its magnetic force partial offset, and attraction is not enough.
Summary of the invention
For addressing the above problem, it is a kind of simple in structure that the utility model provides, and has many grades of adjustable safety door latchs.When using unicoil in addition instead and strengthening automatically controlled opening the door to stirring the gravitation of memory bar, thereby guarantee reliablely and stablely lock to be opened.
This door lock mainly comprises following assembly: lock body drain pan, lock body cover, poke rod, clamping block, clamping block support, commentaries on classics tongue, lock body door holder casing, coil.It is characterized in that: the clamping block support at clamping block rear is provided with jack, and the piece of transferring the files is housed in the jack.The described piece of transferring the files is provided with three different gears.Three gears realize one respectively. change tongue and regain the noiseless of closing the door; Two. change tongue and stretch out and need turn the key in the lock or inside touches the coil electricity poke rod to open the door; Three. change tongue and stretch out the inside and outside key three kinds of different-effects that all can't open the door.
Wherein said coil adopts single magnetic coil.The magnetic line of force that single magnetic coil sends when connecting power supply forms the magnetic coil of a closure, thereby strengthens the attraction to poke rod, improves the reliability of opening the door.
The mode of unblanking, as shown in the figure, the outside makes and opens the lock with the key when the lock adjustment piece is in 21 positions of the piece of transferring the files, and innerly uses key, makes coil electricity or the use pull bar of transferring the files make the lock adjustment piece reach 20 positions to unblank.Both can use key or mechanical cipher to unblank; Also can use contact or untouchable IC, ID, TM card, fingerprint and touch information button and unblank.
The utility model advantage
This door lock adopts changes tongue, and simple in structure, noise is low; Be provided with three positions on the gear shift piece, can realize different effects, safe and reliable; Adopt unicoil to substitute twin coil, increase attraction, can stablize and realize the no key operated of inside poke rod, convenient succinct, be fit to common metal structure or wooden structures door and install and use.
Description of drawings
Fig. 1 is the utility model door shrinking structure schematic diagram.
Fig. 2 is that the utility model piece of transferring the files is partly located structural representation.
Fig. 3 is the utility model piece place schematic diagram of transferring the files of transferring the files.
Among Fig. 1,1-lock body cover, 2-poke rod, the rotating shaft of 3-poke rod, the 4-clamping block, the rotating shaft of 5-clamping block, 6-clamping block support, 7-changes tongue, 8-changes tongue rotating shaft, 9-lock body door holder casing, 10-lock body drain pan, the 11-piece of transferring the files, the 12-pull bar of transferring the files, 13-lock adjustment block reset spring, 14-clamping block adjusting rod, 15-coil, 16-coil brace, the 17-ball, the vertical rod of 18-cylindricality, 19-spring.
Among Fig. 3,20-gear one, 21-gear two, 22-gear three.
The specific embodiment
The utility model is with reference to as Fig. 1 structural representation each parts being assembled into door lock.Each parts metal material processing among the embodiment.Changeing tongue 2 fastens at lock body drain pan 10 right-hand by changeing tongue rotating shaft 8; Clamping block 4 is positioned at the left of commentaries on classics tongue 2 and fastens on clamping block support 6 by clamping block rotating shaft 5, twist-lock piece 4 makes the one end be stuck in the draw-in groove that rotates tongue, and connect lock adjustment block reset spring 13 by lock adjustment piece 14, the lock adjustment block reset spring other end is fixed in lock body drain pan 10.Poke rod 2 fastens at lock body drain pan 10 by poke rod rotating shaft 3.
Mobilizable piece 11 of transferring the files is set on the clamping block support 6 at clamping block 4 rears.The piece 11 of transferring the files is provided with three different gears (as shown in Figure 3).When clamping block adjusting rod 14 is positioned at gear 1, changes tongue and regain the noiseless of closing the door; When clamping block adjusting rod 14 is positioned at gear 2 21, changes tongue and stretch out and to turn the key in the lock or inside touches the coil electricity poke rod to open the door; When clamping block adjusting rod 14 is positioned at gear 3 22, change tongue and stretch out the inside and outside key three kinds of different-effects that all can't open the door, have only by the pulling pull bar 12 of transferring the files and to realize opening the door or closing the door.
The above-mentioned piece base of transferring the files is provided with sawtooth, and frame bottom is provided with cylindricality vertical rod 18, and the interior sky of cylindricality vertical rod also is equipped with spring 19, and card has ball 17 above the spring, and the piece sawtooth card of transferring the files is pressed on the ball, and structure as shown in Figure 2.This structure is exchanged link stopper and is played support and make things convenient for the slip effect.
Coil 15 adopts single coil, and coil is vertical mutually with poke rod.Compare with two coil configuration arranged side by side, the magnetic force that the energising back is produced is stronger, and is big to the attraction of poke rod, improves the reliability of opening the door.Coil 15 fastens on lock body drain pan 10 by coil brace 16.Work as coil switch power, attract poke rod, poke rod touches clamping block, and making changes the tongue withdrawal, realizes the unlatching of door lock.
Lock body door holder casing 9 is also made P shape shell with metal material, and when the shell limit had notch and 10 assemblings of lock body drain pan, the commentaries on classics tongue can be stretched and forward in the lock body door holder casing 9, so that with the safe and reliable locking of door.
