Abstract

The invention provides an acousto-optic multifunctional lock, which relates to a lock and accessories, wherein a transmission part 7 with a fixed supporting point or a straight spring 5 presses and closes a baffle plate 2 and a switch 6; a front hole and a rear hole of a support 1 of a lock hole baffle plate which can be smoothly pushed away by a flat-headed key of which the front end does not comprise a chamfer angle or a rounded angle are not concentric; a guide surface 3 of the support forms an eccentric hole on the front side; a rear hole and a lock core hole are correspondingly concentric; a working surface 4 is formed between an eccentric front hole and a rear hole; the guide surface 3 and the working surface 4 are arranged on the baffle plate; the spring 5 does not contact a manual baffle plate when the manual baffle plate is closed, and contacts the baffle plate when the baffle plate starts to move so as to switch on a circuit or switch off a switch provided with a normally closed contact by pressing when the baffle plate is closed; when the baffle plate starts to move, the switch is switched on; the spring 5 for improving the adaptability of the switch is arranged at the rear end of a switch 6; and an acoustic generator 10 is arranged on a manual bearing 8 to ensure that sound is given out from a keyhole. By the acousto-optic multifunctional lock, when a door is opened by force or is not closed well, an alarm is given out; and an alarm signal is output after time delay is set at the back of the switch which is connected with a movable lug.

Description

The acousto-optic multi-functional lock

Technical field: the present invention relates to multifunctional lock, particularly with the alarming lock of preventing universal key, pick-proof.

Background technology: need use methods such as chamfering, angle, garden in order to push the sideboard that moves on the plane open usually, make the tiny baffle plate that inserts closure of key front end; In order to finish Pickproof alarm, need to work in coordination and finish with slow-witted ligule attitude switch and movable lug status switch or other displacement body switch.

Summary of the invention: invention is " acousto-optic multi-functional lock " patent further to be improved perfect, makes front end not have the tack key at chamfering or angle, garden also can push the Back plate for lock hole that move on the plane smoothly open; Sound hole manual Back plate for lock hole that can not be closed and the warning function that increase is forced open the door and Men Wei shuts are provided, can also point out owner not leave behind key and lock door.

Baffle plate that this tack key that can make front end not have chamfering or angle, garden also can be pushed open smoothly is mainly by 1, support; 2, baffle plate; 5, spring; 7, driving member constitutes.Accompanying drawing: 1,2,3,4,5,6,7 is schematic diagram, it is characterized in that: T type driving member 7 or straight spring 5 pressing baffle plates 2 and switch 6 closures of doing circular motion with the band fixed support; Support 1 front aperture and back face decentraction, at the preceding eccentric orfice that forms, back face side is corresponding with lock core hole concentric by support spigot surface 3, forms work plane 4 between preceding hole of off-centre and metapore, and spigot surface 3 work planes 4 are also arranged on the baffle plate.After the vision lockhole insertion that key is formed by spigot surface, contact the work plane of support and baffle plate again, by the support work plane key guiding lock core hole center while key is also promoted the baffle plate translation, the thrust that it and key produce on the baffle plate work plane promotes baffle plate jointly.Keyhole is less than or equal to the width of baffle plate 2 on the rack plate, can prevent moving behind the baffle plate.

Accompanying drawing 13,14, be housing, lock core locating hole 16 and the installation position 14 of support installing hole 17 driving member installation positions 18 and switch 6 and the installation position 15 of switch spring are arranged on housing 13; Accompanying drawing 15 has in switch 6 rear ends and improves spring 5 its Strong degree Dayu switch 6 contained springs that switch adapts to the different size displacements of baffle plate, and at first pull switch moves thereafter that switch moves with baffle plate when object promotes baffle plate.

Manually Back plate for lock hole is mainly by manual baffle plate supporting 8, manual baffle plate 9, spring 5, switch 6, acoustical generator 10, lock panel 11, lock core 12 is formed, accompanying

drawing

9,10,11,12 is schematic diagram, alternate manner and baffle plate insulation are made or are adopted in supporting by insulation materials, it is characterized in that: spring 5 its contact of when flapper closure, getting along well, baffle plate begins to open when mobile and contacts with baffle plate, connect circuit or when flapper closure the switch of compression band normally closed contact disconnect, and baffle plate begins to open the promptly closed connection of mobile switch, spring can also make the baffle plate location when baffle plate is opened, prevent to fall after rise, on near the manual supporting 8 of lock core hole, acoustical generator 10 is installed or between acoustical generator 10 and keyhole, is used transaudient passage, resonant cavity links to each other, and chimes of doom spreads out of from the keyhole of panel 11.

Force open the door and Men Wei shuts warning and mainly is made up of movable lug shift switching, time-delay electricity, also can behind switch, add spring with embodiment 7 is the same, to adapt to the mobile of movable lug and the sensitivity of raising switch; With switch that movable lug links to each other after increase a delay circuit after output alarm signal again, like this when the normal switch door, time of switch connection or disconnection is short can not to start warning, and Men Wei shuts and force open the door its time that is switched on or switched off to be surpassed set promptly to start and report to the police.Usually in little vapour Trucks, all there is one and detects the device whether the Trucks door has shut, its switch can be connected indicator lamp when door is opened or do not shut, we can be placed in this device on other common door leaf and the doorframe or be placed on the side panel of lock body, different is to close its switch of back at door leaf promptly to connect or trigger playback circuit, play cuing owner does not leave behind key and locks door or the careful voice of driving several times of fastening seat belts, and detectable people different situations inside and outside chamber or Trucks are selected to play.
