Description

The core-inset type electric control door lock that the access door function is arranged

The utility model relates to a kind of lockset, particularly a kind of core-inset type electric control door lock that the access door function is arranged.

The electric control door lock of Xiao Shouing mainly is made up of handle, motor and wind tongue in the market, the input control signal of telecommunication when opening the door, and the mechanical part that the motor drives transmission mechanism will link to each other with handle is opened.The rotation handle, the wind tongue produces retraction, and door is opened.Its defective is: must make motor operation or open tapered end with mechanical key by input electrical signal when entering, door could be opened at every turn.When the door that is installed in frequent discrepancy is gone up, make troubles to use.

The purpose of this utility model is that a kind of core-inset type electric control door lock that the access door function is arranged will be provided, and it can make door be in normal on off state, can make door be in normal locking states again.

The utility model is achieved in that on the handle axle and is with ratchet, wind tongue arm-tie, the moving plate of wind lingual ribbon and the moving plate shifting block of wind lingual ribbon are housed between ratchet and wind tongue, worm gear, worm screw, swing arm and electronic ratchet are housed between ratchet and motor, between ratchet and access door knob connector, manual ratchet and anti-ratchet are housed.Motor pawl and manual ratchet are contained on the control panel simultaneously, and control panel and the moving plate shifting block of wind lingual ribbon are fixed together.When using as access door lock, rotating channel door knob connector, anti-ratchet and manual ratchet rotate simultaneously, manually pawl-and-gearing engagement.When rotating handle by hand, the handle axle drives ratchet, manually the moving plate shifting block of ratchet, control panel and wind lingual ribbon rotates together, the moving plate shifting block of wind lingual ribbon is stirred the moving plate of wind lingual ribbon, the moving wind tongue arm-tie of the moving strip of wind lingual ribbon, the spring that the compression of wind tongue arm-tie is contained in its rear portion moves backward, dead bolt is withdrawn in the lock body, and door is unlocked.When unclamping hand, in lock body, eject at the effect leeward tongue of spring force.At closing time, the wind tongue bumps and produce retraction on doorframe, after putting in place, ejects again under the effect of spring force, shuts the door, and lock just is in the access door state.Opposite spin access door knob connector, manually ratchet separates with ratchet, and lock just is in locking states.When the input of the control signal of telecommunication, motor makes electronic ratchet and ratchet engaged by the worm and gear transmission, rotate handle by hand, the handle axle drives the moving plate shifting block of ratchet, electronic ratchet, control panel and wind lingual ribbon and rotates together, the moving plate shifting block of wind lingual ribbon is stirred the moving plate of wind lingual ribbon, the moving wind tongue arm-tie of the moving strip of the wind lingual ribbon tongue of keeping watch is withdrawn in the lock body, and door is unlocked.Electronic ratchet makes the swing arm that is contained on the worm gear put an angle simultaneously, when unclamping hand, along with the control panel opposite spin, electronic ratchet turns over an angle in the other direction again under the effect of swing arm separates with ratchet, the wind tongue ejects in lock body again, when rotating handle by hand once more, and ratchet idle running, lock is opened, and promptly lock is in locking states.

The utility model brings convenience to use owing to adopt ratchet and the electronic ratchet engagement different with manual ratchet to realize locking, unlatching and the normal switching function of door.

Accompanying drawing is the longitudinal sectional view of the utility model embodiment.

With reference to accompanying drawing, in lock housing (25), be with ratchet (21) on the handle axle (20), wind tongue arm-tie (6), the moving plate (10) of wind lingual ribbon and the moving plate shifting block (23) of wind lingual ribbon are housed between ratchet (21) and wind tongue (8), worm gear (3), worm screw (2), swing arm (4) and electronic ratchet (9) are housed between ratchet (21) and motor (1), manual ratchet (19) and anti-ratchet (17) are housed between ratchet (21) and access door knob connector (15).Electronic ratchet (9), manual ratchet (19) and anti-ratchet (17) are contained on the control panel (12) by axle (22), (18) and (16) respectively, and control panel (12) is fixed together with the moving plate shifting block (23) of wind lingual ribbon.When using as access door lock, rotating channel door knob connector (15), anti-ratchet (17) rotates around axle (18) simultaneously around axle (16) and manual ratchet (19), manually ratchet (19) and ratchet (21) engagement.When with hand operation handle (not drawing among the figure), handle axle (20) drives ratchet (21), manually the moving plate shifting block (23) of ratchet (19), control panel (12) and wind lingual ribbon rotates together.The moving plate shifting block (23) of wind lingual ribbon is stirred the moving plate (10) of wind lingual ribbon, the wind lingual ribbon moves plate (10) and drives the wind tongue arm-tie (6) be contained in below it by a rivet (5), the spring (14) that wind tongue arm-tie (6) compression is contained in its rear portion moves horizontally, the tongue (8) of keeping watch is withdrawn in the side panel (11) of lock body, and door is unlocked.Unclamp handle, under the effect of spring (14) elastic force, wind tongue (8) is released from the side panel (11) of lock body by wind tongue arm-tie (6).At closing time, wind tongue (8) bumps and compress spring (7) generation retraction on doorframe.After door closes and to put in place, eject in lock body again at the effect leeward tongue (8) of spring (7) elastic force, door is shut.This moment, door just was in the access door state.Opposite spin access door knob connector (15), releasing is to the supporting role of anti-ratchet (17), at this moment anti-ratchet (17) produces counter-rotation around axle (16) under the effect of spring (13) makes manual ratchet (19) separate with ratchet (21), and lock just is in locking states.When the input of the control signal of telecommunication, motor (1) makes electronic ratchet (9) and ratchet (21) engagement by the transmission of worm gear (3) and worm screw (2).Rotate handle by hand, handle axle (20) drives ratchet (21), ratchet (21) passes to the moving plate shifting block (23) of wind lingual ribbon by electronic ratchet (9), axle (22) and control panel (12) with rotation, the moving plate shifting block (23) of wind lingual ribbon promotes the moving plate (10) of wind lingual ribbon, the wind lingual ribbon moves plate (10) and drives wind tongue arm-tie (6) tongue (8) of keeping watch and be withdrawn in the lock body side panel (11), and door is unlocked.Simultaneously, the frictional force that the gap portions of electronic ratchet (9) forces the swing arm (4) that is contained on the worm gear (3) to overcome between axle (24) and the worm gear (3) was put an angle, when unclamping handle, along with control panel (12) opposite spin, electronic ratchet (9) also turns over an angle in the other direction again under the effect of swing arm (4) separates with ratchet (21), and wind tongue (8) ejects in lock body again.When using the hand operation handle once more, ratchet (21) idle running can't make lock open, and promptly lock is in locking states.

Claims (1)

1, a kind of lock of forming by handle axle (20), ratchet (21), motor (1), wind tongue (8) and access door knob connector (15), it is characterized in that being with on the handle axle (20) ratchet (21), wind tongue arm-tie (6), the moving plate (10) of wind lingual ribbon and wind are housed between ratchet (21) and the wind tongue (8) drive plate shifting block (23), worm gear (3), worm screw (2), swing arm (4) and electronic ratchet (9) are housed between ratchet (21) and the motor (1), manual ratchet (19) and anti-ratchet (17) are housed between ratchet (21) and the access door knob connector (15).
