Abstract
The utility model discloses an alarm switch for an anti-burglar door, composed of two horizontal L-shaped shifting levers and two switches. The two shifting levers are both provided with rotating shafts, banking screws and reset springs, which are totally fixed to base plates of the shifting levers. The base plates of the shifting levers are connected with a moving lever of a lock bolt into integration. Each shifting lever corresponds to a switch which is fixed to a door panel of the burglar-proof door. When the moving lever of the lock bolt moves up and down, the shifting levers can push the corresponding switches to start or close the alarm device for automatic setting and release. The device has the advantages of simple structure, firm and durable structure, and strong reliability.
Description
The utility model relates to the alarm switch of a kind of alarm switch, particularly security door alarm device.In more regular security door device, mostly dispose alarm switch, these alarm switches generally all manually start and cut out when coming in and going out by the user, because human negligence, forget the unlatching warning device and feed robber person with opportunity, thereby the warning device of more senior security door all adopts the mode that triggers automatically with releasing that is provided with, the moving bar interlock of mechanical type starting switch and door lock or lock bolt, stir the warning starting switch when utilizing the moving bar of unlatching lock or lock bolt to move up and down, moving bar adopts rigid structures, when opening and remove starting switch is to stir firmly, time has been grown starting switch and has been easy to damage, and makes troubles to the user.Also have a kind of electron type starting switch in addition, utilize circuit to finish the startup and the releasing of warning device, this switch motion sensitivity, volume are small and exquisite, but because of household electrical appliance in the resident family at present roll up, are easy to generate the interference signal of telecommunication, cause that action is malfunctioning.Therefore the starting switch of security door alarm device is that mechanical type or electron type all have poor reliability, flimsy shortcoming at present.
The purpose of this utility model provides a kind of switch that can start and remove warning device automatically easy to use, not fragile, robust.
The purpose of this utility model is achieved in that
A kind of security door alarm switch, it comprises switch and driving lever, its basic improvements are: driving lever 4 has two, be horizontal L type, there is turning cylinder at place, top, right angle at each driving lever, there are stop screw and back-moving spring in the vertical straight arm of angle outside at driving lever, turning cylinder, stop screw and back-moving spring all are fixed on the driving lever substrate, the moving bar of the latter and lock bolt is connected as a single entity, switch is two, each switch is corresponding with the straight horizontal arm of angle of a driving lever respectively, and switch is fixed on the honorable plate of door of security door.
Above-mentioned alarm switch, the work plane that is used for toggle switch on the described driving lever 4 straight horizontal arms of angle is the inclined-plane.
After adopting this switch, use to rotate the moving lever lock door of lock bolt or when opening the door, corresponding driving lever will finish the operation that starts or cut out warning device respectively by pull switch, because being used for the work plane of toggle switch on the driving lever straight horizontal arm of angle is the inclined-plane, so can rigid impact switch, avoid damage, prolonged the application life of components and parts.And reverse when mobile at the moving bar of lock bolt, driving lever then can rotate around it axle and turn an angle, can touch switch, cause misoperation.This switch structure is simple, and is sturdy and durable, good reliability.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the B-B sectional view of Fig. 1;
Fig. 3 is that the utility model is at the installation site of door body schematic diagram;
Concrete structure of the present utility model as we can see from the figure and mode of occupation: the driving lever that shows two switches and two correspondences among the figure, wherein, the switch of top is a starting switch 2, lower switch is a cancel switch 3, when the user locked a door, the moving bar 9 of lock bolt was moved upward, and drives driving lever substrate 8 and moves upward together, be positioned at top driving lever 4 on the driving lever substrate 8 when moving up, the straight horizontal arm of angle of driving lever touches mutually with the button of starting switch 2.Because stop screw 6 is spacing, driving lever 4 can not rotate counterclockwise, and the straight horizontal arm of angle work plane of last driving lever 4 is about to pressing switch to open of starting switch, and warning device is placed in starting state immediately; When the user opened door, the moving bar 9 of lock bolt moved downwards, and the button of cancel switch 3 was closed warning device below the below driving lever on the driving lever substrate 8 promoted with above-mentioned same action.When the moving bar of lock bolt is mobile downwards, last driving lever (4) also moves down, when driving lever straight horizontal arm of angle lower limb touches the button of top starting switch, last driving lever 4 moving axis 5 that can rotate clockwise rotates, stop screw 6 did not influence and clockwise rotated this moment, driving lever 4 can not promote the button of starting switch 2, by back-moving spring driving lever 4 is resetted then.In like manner, when below driving lever 4 moves up at the moving bar 9 of lock bolt, also can turn an angle, avoid pressing the button of below cancel switch.Can see also that on scheming on the moving bar of lock bolt, following have two extreme positions when mobile, the upper and lower driving lever 4 of Yi Donging also has two upper and lower extreme positions thereupon, just is fixed on its relevant position with each driving lever 4 corresponding starting switch 2 and releasing switch 3.
Claims (2)
1. security door alarm switch, it comprises switch and driving lever, it is characterized in that: it is made up of two horizontal L type driving levers and two switches, there is turning cylinder (5) at the place, top, right angle of described driving lever (4), there are stop screw (6) and back-moving spring (7) in the vertical straight arm of angle outside at driving lever (4), turning cylinder (5), stop screw (6) and back-moving spring (7) all are fixed on the driving lever substrate (8), and the latter and lock bolt move bar (9) and be connected as a single entity; Described switch is two, is respectively starting switch (2) and removes switch (3), and each switch is corresponding with the straight horizontal arm of angle of a driving lever (4) respectively, and switch is fixed on the honorable plate of door (1) of security door.
2. security door alarm switch according to claim 1 is characterized in that: the work plane that is used for toggle switch on described driving lever (4) the straight horizontal arm of angle is the inclined-plane.
