Description

Door lock

[technical field]

The utility model relates to a kind of door lock, relates to a kind of door lock with memory function specifically.

[background technology]

Existing gate, the community residential building road lock that installs an iron door to guard further against burglars is in case external personnel arbitrarily pass in and out.Existing door lock all adopts Electronic Control to produce certain delay in case door lock is opened again door lock not to be lived when passing in and out as yet the user.During Electronic Control because power supply must be arranged, just this kind door lock can't be controlled when situation such as outage takes place.I once designed a kind of rote memory door lock, was 02272696.9 utility model patent referring to State Intellectual Property Office's patent No., and this rote memory door lock is by the shell fragment control of clamping block top, by shell fragment with block clamping block and reach memory function.Shell fragment is long-time to be used or because of vibration deformation easily causes breaking down or controls insensitively, therefore needs improve this.

[summary of the invention]

[technical problem that will solve]

The purpose of this utility model provides a kind of door lock of rote memory delay feature, at dead bolt link stopper side or back elastic device is set, and controls clamping block by elastic device and realize the memory and delay function respectively under the state of Push And Release.

[technical scheme]

The utility model is realized by the following technical solutions: door lock mainly comprises with lower member: cover, drain pan, door holder casing, commentaries on classics tongue, clamping block, slide block and magnetic inductor; Cover and drain pan are rectangle, and cover and drain pan lump together dress and live whole lock body; Change tongue and be fixed on the commentaries on classics tongue support, be equipped with reduction torsion spring in commentaries on classics tongue support one side by rotating shaft; Clamping block is installed in by rotating shaft on the clamping block support that changes the tongue rear end, and clamping block is corresponding with the draw-in groove position of changeing tongue, and the piece on the slide block is enclosed within on the pillar and with magnetic inductor and forms the magnetic lever system; It is characterized in that: a side or rear end at clamping block are provided with memory storage, and described memory storage has following several implementation,

It is 1), wherein a kind of in the clamping block rotating shaft of original clamping block support one side, being provided with " 7 " shape piece; " 7 " the shape piece can rotate around the clamping block rotating shaft; " 7 " one side the shape piece be provided with outstanding link stopper; " 7 " shape piece bottom is connected with extension spring; slide block integral body is shape, and the end of slide block is located at " 7 " the link stopper place of shape piece top.

2), another kind of scheme is that the end of slide block is established upwards and the sideways fixture block of stirring, the drain pan of clamping block one side is provided with vertical shaft, be with two sliding pieces on the vertical shaft, top sliding piece is stuck between slide block and the clamping block rear end, sliding piece is provided with draw-in groove, and the fixture block that slide block makes progress is arranged in the draw-in groove; Following sliding piece vertical view is V-shaped, and its inboard is provided with the torsion spring that is enclosed within on the vertical shaft, and V-arrangement sliding piece dorsal part touches with changeing whip graft, and the end of opposite side is provided with stepped latch, and latch contacts with slide block side fixture block.When lock is in closed condition and need opens the door, stir slide block with key or button, the fixture block of stirring that the slide block end makes progress slides along sliding piece, force and stir fixture block to the sinciput clamping block, clamping block sways, the clamping block front end leaves changes the tongue draw-in groove, and the commentaries on classics tongue rotates then to lock under action of reset spring and opens; This moment is not if door is open, the V-arrangement sliding piece is under action of reset spring, the ladder latch blocks the fixture block of slide block side just at this moment well, and then whole lock is in the rote memory state, changes tongue and rotate and force the vertical V-arrangement sliding piece cancellation remember condition that resets after door is open.

3), on the support shaft of clamping block, be connected with the casing that can seesaw, be provided with T shape bar in the middle of the casing, be with spring on the T shape bar, a side at casing rear portion is provided with hole clipping, casing is limited and can only seesaw by iron plate or iron case, and its T shape bar one end inserts in the fixing hole of iron plate or the setting of iron case.Casing can only seesaw under the qualification of iron plate and support shaft and under the effect of T shape bar upper spring.Spiral shell has movable switch block on the drain pan, and movable switch block one side is established stepped latch, and this latch is corresponding with the screens that the slide block lower end is provided with, and movable switch block opposite side is provided with grab, and grab hooks hole clipping.Stir the phase bar and rotate when unblanking, movable switch block skids off from screens, and before the effect lower box of spring was pushed to, clamping block rotates around the axis to leave changeed the tongue draw-in groove.If door is not open, casing ejects forward and withstands the commentaries on classics tongue, and can be in remember condition this moment always, changes the tongue rotation and force casing to retreat when door is open, grab in the casing hole clipping is and then retreated and around screw turns, the screens of the stepped latch rechuck of movable switch block slide block.

[beneficial effect]

Adopt its stable performance of the utility model, not fragile, memory function is strong, and it is simple in structure, makes easy for installationly, has overcome the defective that can't realize memory function of existing electronic lock when cutting off the power supply.
