Abstract

The utility model discloses a door-handle with an alarm device. The door-handle comprises a door-handle and a base which is fixed on a door and connected with the door-handle, wherein the tail end of the door-handle is provided with a tail cover, the inside of the tail cover is provided with batteries and an alarm horn, the batteries and alarm horn are electrically connected with a gate controlled switch, the gate controlled switch comprises a reed switch and a permanent magnet, the reed switch is arranged in the base of the door-handle, and the permanent magnet matched with the reed switch is arranged on the door-handle side of the doorframe. The door-handle with the alarm device is not easy to find, and when the thief twists the door-handle to open the door, the alarm device is triggered to give an alarm, thus the utility model is convenient and practical.

Description

A kind of catch with warning device

Technical field

The utility model relates to a kind of warning device, refers to a kind of catch with warning device especially.

Background technology

Though our living standard is improving constantly, people's overall qualities also are all to advance with day, but it is unearned still to exist some people to wish in the life, this part crowd is exactly the thief, they steal by the family that enters others stealthily, safety how to strengthen family's property is the target of security expert effort always, more complicated in addition in the room around camera is installed, constantly monitor, obviously such mode is not suitable for the ordinary people, we just wish to force open the door the thief, the sled window can send alarm when wanting to enter the room, remind the household to note, frighten away and deter the thief in other words, therefore, develop a simple in structure, lower-cost alarm is the target of everybody effort always, but general alarm is often disguised less, experienced thief is very easy to find and will forces open the door into after its dismounting again, and developing a disguise warning device better and that can combine closely with surrounding enviroment is the main purpose of this patent.

The utility model content

Technical problem to be solved in the utility model provides a kind of catch with warning device, the catch of this band warning device designs the permanent magnet in the gate controlled switch on the doorframe on catch next door, and the tongue tube in the gate controlled switch is designed in the pedestal of catch, other components and parts designs are in the tail-hood of catch afterbody, thereby be not easy to be found, it is, convenient and practical as long as thereby the thief turns and just triggered warning device when catch opens the door and send alarm sound.

In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:

A kind of catch with warning device, comprise a catch, one is fixed on the pedestal of the connection catch on the door, described catch tail end also is provided with a tail-hood, the tail-hood content is provided with battery and alarming horn, and battery and alarming horn are electrically connected with gate controlled switch, and described gate controlled switch comprises a tongue tube and a permanent magnet, described tongue tube is arranged in the pedestal of catch, and the described permanent magnet that cooperates with tongue tube is arranged on the doorframe of catch one side.

In the pedestal that the utility model is separately positioned on catch by tongue tube and magnet with gate controlled switch and on the doorframe of catch one side, during concrete the use, magnet can be fixedly installed on the doorframe of catch one side, then tongue tube is arranged in the pedestal of catch, so just formed a very hidden warning device, whoever can not expect that this catch is exactly a warning device in fact.When the thief spurs catch, will make the tongue tube in the gate controlled switch leave magnet, send alarm thereby touch gate controlled switch, reach the purpose of warning.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is elaborated:

Fig. 1 is the circuit diagram of gate controlled switch of the present utility model;

Fig. 2 is a circuit theory schematic diagram of the present utility model;

Fig. 3 is the utility model apparatus structure schematic diagram.

Among the figure:

1, permanent magnet 2, tongue tube 3, resistance 4, Schmidt's NAND gate

5, gate controlled switch 6, alarming horn 7, pedestal 8, catch

9, tail-hood 10, battery

The specific embodiment

As Fig. 2, shown in Figure 3, a kind of catch with warning device, comprise a catch 8, one is fixed on the pedestal 7 of the connection catch 8 on the door, catch 8 tail ends also are provided with a tail-hood 9, and tail-hood 9 contents are provided with battery 10 and alarming horn 6, and battery 10 and alarming horn 6 are electrically connected with gate controlled switch 5, the tongue tube 2 of gate controlled switch 5 is arranged in the pedestal 7 of catch 8, and the permanent magnet 1 that cooperates with tongue tube 2 is arranged on the doorframe of catch 8 one sides.

As shown in Figure 1, gate controlled switch 5 comprises a tongue tube 2 and a permanent magnet 1, resistance 3, Schmidt's NAND gate 4, tongue tube 2 is arranged on the door and window, permanent magnet 1 is arranged on the door window frame, its control principle is: when door is closing, magnet makes its junction closure, Schmidt's NAND gate 4 output low levels near tongue tube 2; When door was opened, magnet has left tongue tube 2 disconnected its contact, Schmidt's NAND gate 4 output high level, thus realize switch control.

During concrete the use, magnet 1 can be fixedly installed on the doorframe of catch 8 one sides, tongue tube 2 is arranged in the pedestal 7 of catch 8 then, has so just formed a very hidden warning device, whoever can not expect that this catch is exactly a warning device in fact.When the thief spurs catch, will make the tongue tube 2 in the gate controlled switch 5 leave magnet 2, send alarm thereby touch gate controlled switch 5,

Those skilled in the art will recognize that, the above-mentioned specific embodiment is exemplary, be in order better to make those skilled in the art can understand this patent, can not be interpreted as it is the restriction that this patent is comprised scope, so long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.

Claims

1. catch with warning device, comprise a catch, one is fixed on the pedestal of the connection catch on the door, it is characterized in that: described catch tail end also is provided with a tail-hood, the tail-hood content is provided with battery and alarming horn, and battery and alarming horn are electrically connected with gate controlled switch, and described gate controlled switch comprises a tongue tube and a permanent magnet, described tongue tube is arranged in the pedestal of catch, and the described permanent magnet that cooperates with tongue tube is arranged on the doorframe of catch one side.
