Abstract
A door lock device with an automatic unlocking function is disclosed, comprising an electromagnetic device, a fuse, and switches, wherein an electromagnetic coil, an iron core, an iron block, and a current-limiting resistor are embedded inside the electromagnetic device, a spring is placed between the iron block and an inner wall of the device, the iron block is connected with an outer metal block through a thin metal rod, and the metal block is provided with a hook. When the lock device is used, the number of leading-out wires can be set based on use requirements, and the switches can be arranged at a place (such as a bedside or a desk) that is convenient for users to reach. Automatic unlocking of a door lock can be realized by pressing any switch, and the door lock can be back to the original state by pressing the switch again. Convenience of opening a door in a school dormitory is realized and trouble of opening the door is reduced.
Description
Technical field:
The utility model relates to a kind of device of the lock that is used for opening the door automatically, belongs to the small electric apparatus technical field.
Background technology:
Known, it is shared that the bedroom is generally many people in the campus, and when the people knocked at the door, bed went to open the door from the closer classmate of door often, and this meeting causes certain burden to the classmate that bed is in this position.In addition, evening, if there is the people to knock at the door, often very unwilling the leaving the bed of classmates opened the door when everyone is in bed the time in the bedroom.
Summary of the invention:
To the problem that exists in above-mentioned, the utility model proposes the way of solution, and its technical scheme is following.
A kind of locking device that opens the door automatically, it comprises calutron, fuse, switch.Calutron inside is embedded with electromagnetic coil, iron core and iron block; Electromagnetic coil is around on the iron core and is connected to current-limiting resistance; Be provided with spring between iron block and the device inwall, and link to each other with the metal backup of outside through thin metal bar through-going device wall, metal backup is provided with hook.Coil is drawn through lead, through overcurrent fuse and switch, finally is connected on the power supply.
The beneficial effect of the utility model is:
The utility model is convenient and practical, and price is more cheap, has reduced the trouble of bedroom, campus inward, is adapted at promoting in the bedroom, campus installing.
Description of drawings:
Below in conjunction with accompanying drawing and embodiment further to the utility model explanation.
Fig. 1 is a kind of structural representation of the locking device that opens the door automatically.
Among Fig. 1: the 1-door lock, the 2-hook, 3-metal backup, 4-spring, 5-iron block, 6-metal be rod carefully, 7-electromagnetic coil, 8-iron core, 9 (1), 9 (2)-fuses, 10 (1), 10 (2)-switches, 11-power supply, 12-current-limiting resistance, 13-calutron shell.
The specific embodiment:
As shown in Figure 1, a kind of locking device that opens the door automatically.Electromagnetic coil 7 is around on the iron core 8, and is connected to current-limiting resistance 12, and whole electromagnet is in stationary state.Be provided with iron block 5 with iron core 8 relative positions.The opposite side of iron block 5 is embedded with the thin rod 6 of metal, and passes calutron shell 13 and link to each other with metal backup 3.There is spring 4 to link to each other between the inwall of iron block 5 and calutron shell 13.The opposite side of metal backup 3 is embedded with hook 2.Hook 2 directly links to each other with the handle of door lock.Electromagnetic coil 7 is drawn through lead, and wherein a lead can be divided into multiple conducting wires, and is connected on the switch 10 through fuse 9 respectively.The outlet of switch 10 is connected on power supply 11 live wires, and another root lead is connected on power supply 11 zero lines.During use, can the lead-out wire number be set, and be located at the more convenient place's (on bed side or desk) that touches of personnel to switch 10 according to user demand.Press switch 10, electromagnetic coil 7 gets the electrician and does, and electromagnetic actuation iron block 5 also drives metal backups 3 and hook 2 motions through metal thin excellent 6, thereby has realized opening of door lock 1.Press switch 10 once more, this moment electromagnetic coil 7 dead electricity, electromagnet does not have suction, iron block 5 is the reinstatement attitude under the effect of spring 4, this moment, door lock 1 restored to the original state.
The basic principle and the principal character of the utility model have more than been described.The utility model is not restricted to the described embodiments; The foregoing description has just been explained the principle of the utility model; Under the prerequisite that does not break away from the utility model spirit and scope; The utility model also has various changes and modifications, and these variations and improvement all will fall in the utility model scope that requires protection.
