In conclusion problem of the existing technology is：Existing latch door flexibility is poor, it has not been convenient to operate；Safety
It is poor, it is easier to be forced to push open after locking a door, it will be cumbersome after knocker contract fully.
Invention content
In view of the problems of the existing technology, the utility model provides a kind of safety alarm device for latch door.
The utility model is realized in this way the safety alarm device for being used for latch door is provided with fixed plate, it is described solid
Fixed board surface is provided with multiple circular grooves, and being pressed in the circular groove of the top, which has ball to lock a door, buckles, the circular groove of lower end
Interior to be welded by the second connecting rod and electronic knocker, the second connecting rod end is clamped with link block, before link block and telescope motor
End clamping；
Internal side of shell interlocking has pressure sensor, pressure sensor to connect microcontroller by conducting wire, and microcontroller passes through conducting wire
Connect alarm and telescope motor.
The ball is locked a door to buckle and be welded with head rod, and connecting rod is socketed in by rear end spring in square groove, sliding
Block is arranged on the outside of square groove and is welded with connecting rod.The effective control buckled of locking a door to ball is realized by head rod,
Realize that effective cooperation clamping of sliding block and square groove is installed.
The fixed plate surrounding setting is fluted, and fixed plate is fixed on casing right end, telescope motor, pressure sensing by screw
Device, alarm, microcontroller are fixed by screws in casing.It realizes to telescope motor, pressure sensor, alarm, monolithic
Effectively being fixedly secured for machine, loosens after avoiding long-time use.
The advantages of the utility model and good effect are：The safety alarm device design that this is used for latch door is accurate, after touching
It can close the door, it is easy to operate simple；It is safe, electronic knocker can be directly popped up after strong pressure, to prevent from forcing entering the room；Together
When there is alarm, to remind householder, and frighten robber.Operation is simple, safe, has alarm function, highly practical,
With very big promotional value.

Specific implementation mode
For that can further appreciate that the invention, features and effects of the utility model, the following examples are hereby given, and coordinates
Detailed description are as follows for attached drawing.
The structure of the utility model is explained in detail below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, which is provided with fixed plate 1,1 table of the fixed plate
Face is provided with multiple circular grooves 3, in the circular groove 3 of the top pressing there is ball to lock a door to buckle 2, in the circular groove 3 of lower end
Welded by the second connecting rod 10 and electronic knocker 11,10 end of the second connecting rod is clamped with link block 9, link block 9 with it is flexible
6 front end of motor is clamped；
4 inside interlocking of casing has pressure sensor 12, pressure sensor 12 to connect microcontroller 14, microcontroller 14 by conducting wire
Alarm 13 and telescope motor 6 are connected by conducting wire.
The ball, which is locked a door, buckles 2 and the welding of head rod 7, and connecting rod is socketed in by rear end spring in square groove 5,
The setting of sliding block 8 is welded in 5 outside of square groove and with connecting rod.By head rod 7 realize lock a door to ball buckle 2 it is effective
Control realizes that sliding block 8 and effective cooperation clamping of square groove 5 are installed.
The setting of 1 surrounding of the fixed plate is fluted, and fixed plate 1 is fixed on 4 right end of casing, telescope motor 6, pressure by screw
Sensor 12, alarm 13, microcontroller 14 are fixed by screws in casing 4.It realizes to telescope motor 6, pressure sensor
12, alarm 13, the effective of microcontroller 14 are fixedly secured, and are loosened after avoiding long-time use.
The operation principle of the utility model：It is provided with ball in doorframe opposite position and locks a door and buckle 2 with electronic knocker 11
Groove, casing 4 is mounted on inside door side, and when moving door with hand push, ball, which is locked a door, buckles 2 front end balls rollings, coordinates rear end spring
To block the groove on doorframe, head rod 7 can be pulled to buckle 2 so as to pull ball to lock a door by sliding block 8, can opened
Door；After pressure sensor 12 (GML670) experiences pressure, microcontroller 14 (MSP430F149IPMRG4) is passed the signal to
Afterwards, start alarm 13 to alarm, simultaneous retractable motor 6 (XC758-A) works, and drives link block 9 to advance, Jin Ertong
The advance that the second connecting rod 10 drives electronic knocker 11 is crossed, and then electronic knocker 11 is clamped into the card slot of doorframe.
The above is only the preferred embodiment to the utility model, is not made in any form to the utility model
Limitation, it is every according to the technical essence of the utility model any simple modification made to the above embodiment, equivalent variations with
