Abstract
The utility model relates to a door-opening device, in particular to a device which can be used by a user for opening a door in a civilized mode. The door-opening device comprises a handle, an inductive switch, a power supply, a metal bar, a coil, a metal plug pin and a spring, wherein the inductive switch, the power supply, the metal bar, the coil, the metal plug pin and the spring are mounted on the inner side of the handle. The metal bar is connected with the center of the coil in a sleeved mode. The metal bar is connected with the metal plug pin through the spring. When the inductive switch is closed, the power supply provides voltage for the coil. By means of the technical scheme, the user can form a good habit of opening the door in the civilized mode, and the service life of the door and the service life of a door lock are prolonged.
Description
Technical field
The utility model relates to door opener, is specifically related to a kind of device that people's civilization is opened the door.
Background technology
In the life, the door of the external lock of a lot of the sort of usefulness is all easily by artificial damage, some public arenas such as this situation of school is even more serious particularly, and students' union is because naughtyly open the door energetically, overexerts etc. former when causing opening the door thereby reduces application life of door.
So, a kind of door opener need be provided, in time after door lock is opened, also must use correct, civilized mode just can open door.
Summary of the invention
According to the deficiencies in the prior art, the utility model provides a kind of door opener, can allow the people use the mode of civilization to open door lock.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of door opener comprises handle, also comprises the inductive switch, power supply, metal bar, coil, metal bolt and the spring that are installed in the handle inboard, described metal bar socket hub of a spool, metal bar is connected with metal bolt by spring, described inductive switch closure, and power supply provides voltage for coil.
As preferably, metal bar and coil constitute electromagnetic relay.
Adopt technique scheme, make the people form the enlightened good custom of civilization, and prolonged the application life of door and door lock.
Description of drawings
Fig. 1 is a kind of door opener embodiment of the utility model schematic diagram.
Fig. 2 is a kind of door opener example structure of the utility model schematic diagram.
Fig. 3 is a kind of door opener example structure of the utility model explosion views.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Fig. 1 shows the schematic diagram of a kind of door opener embodiment of the utility model, break-make by inductive switch 5 control circuits, inductive switch 5 also is in series with a coil 2, be socketed with metal bar 3 in the coil 2, coil 2 and metal bar 3 constitute an electromagnetic relay, power supply 4 provides voltage for coil 2, also be provided with metal bolt 1 on the metal bar 3, this metal bolt 1 is connected with metal bolt 1 by spring 7, when inductive switch 5 closures, electromagnetic relay produces magnetic force, metal bolt 1 is to metal bar 3 motions, and when inductive switch 5 disconnected, the magnetic force of electromagnetic relay disappeared, metal bolt 1 is moved away from the direction of metal bar 3 by the elastic force of spring 7, gets back to original position.
As shown in Figures 2 and 3, power supply 4 provides voltage for coil 2, and inductive switch 5 is installed in the inboard of handle 6, and when inductive switch 5 was not closed, metal bolt 1 fastened door-plate away from metal bar 3.When door lock is opened, but do not use the civilized mode of opening the door, do not have closed inductive switch 5, metal bolt 1 fastens door-plate away from metal bar 3, and door still can not be opened.Open the door when the mode of using civilization, will touch inductive switch 5, then the electromagnetic relay of metal bar 3 and coil 2 formations produces magnetic force, makes metal bolt 1 can not fasten door-plate.
In a word, the above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim change and modify, and all should belong to the covering scope of the utility model patent.
