Abstract

The utility model relates to a novel sensor for an anti-prizing alarm of a rolling door. The back-mounting plate of the sensor is pasted above the side door of the rolling door. An elastic sleeve which can generate elastic deformation displacement under exogenic action and can be rebounded and reset is arranged in a cylindrical hole of the sensor. A one-way triggering switch is fixed in the elastic sleeve. The axial line of the downward elastic sleeve forms a tilt angle of about 20 DEG with the horizontal line so as to ensure that the one-way displacement triggering switch lies in the normally open state. When the rolling door is prized up, an up spacing baffle plate jacks up the elastic sleeve, so that the elastic sleeve upward generates elastic deformation rotation to switch on the one-way triggering switch to output alarm electric signals. When the up spacing baffle plate continues moving up till disengage from the elastic sleeve, the elastic sleeve is reset by self elasticity and causes the one-way triggering switch to lie in the normally open state waiting for the next triggering.

Description

The novel sensor of rolling screen door Pickproof alarm device

One, affiliated technical field

The utility model belongs to a kind of ohject displacement sensor, especially relates to a kind ofly rolling screen door to be prized generation novel sensor from horizontal reset after top offset is transformed into electrical signal transfer to give warning device.

Two, background technology

1. existing rolling screen door alarm lock device is to adopt the lock control mode of contacting to earth mostly.Its structure is mounted on the rolling screen door lock, the feeler lever that can move up and down is installed in the below of rolling screen door, when rolling screen door is in closed condition, the acting force that feeler lever makes progress with being subjected to backs down and is contained in the microswitch of locking, when rolling screen door is levered up by the thief, feeler lever moves down, and the closed energising of microswitch is reported to the police warning device.In lock core when rotation, cut off the microswitch circuit when owner opens rolling screen door lock with key, even therefore feeler lever moves down also and can not produce warning.

The type sensor has following deadly defect but this lock control is contacted to earth:

(1) rolling screen door lock is easily destroyed or opened by skeleton key, opens the back alarm and can't work.

(2) when forcing open the door, the thief can lift feeler lever or withstand with finger or iron plate, and it can't be moved down, and microswitch carries on as before and headed on and can't cut out by feeler lever, and circuit connects obstructed, and does not report to the police.

(3) connect together because of sensor and lock, installed rolling screen door lock, dismantle original lock earlier just can set up, and the position adjustment is very difficult, very time-consuming when installing.

(4) client who has is unwilling to change own original rolling screen door lock, and this device can't be used.

2. existing rolling screen door warning device also has the employing magnetic induction way, and its structure is laid the inductor that tongue tube (tube of magnetic induction) is housed below door, adorn a powerful magnet on the door body.When rolling screen door was in closed condition, powerful magnet was near inductor, and magnetic field holds the tongue tube in the magnetic inductor, make its disconnection (not reporting to the police), when the thief forced open the door, powerful magnet left inductor, inductor loses magnetic field, and the tongue tube closure is reported to the police warning device.

But this magnetic induction sensing device also has following deadly defect:

(1) because the making precision of rolling screen door is not high, free clearance is very big between door and frame and the ground, makes this device (as wind, child's promotion etc.) under the condition of external force cause false alarm easily or not report to the police.

(2) this device is installed complexity, needs preheating embedding line, thereby can destroy the integrality on original ground, (also not attractive in appearance).

(3) this sensor easily is cracked, and only needs to insert a very little magnet from the gap of door when forcing open the door, and is attached on the sensor, and its tongue tube is disconnected, and just can force open the door easily.

3. existing rolling screen door warning device also has shock sensor, but problem is to have the people to collide a little or the strong wind thunder and lightning all can cause wrong report.Because above-mentioned various sensor all has the defective that is difficult to avoid, and does not have practical value.Therefore reliable and practical rolling screen door alarm still belongs to blank.

Three, summary of the invention

The utility model easily is disengaged at existing rolling screen door alarm sensor function or causes wrong report, install inconvenient, adjust the deficiency of difficulty, a kind of novel sensor is provided, when being prized, rolling screen door can not only send alerting signal reliably, and the thief can't remove and stop the transmission of signal, thereby can not cause and do not report or report by mistake, only needs a few minutes just can install and economical and practical and this alarm is installed.

The technical scheme that the utility model technical solution problem adopts is: the back installation material displacement body sensor in the left side or the offside door side of rolling screen door.In the cylindrical hole of this sensor body, cooperate a spring-backed quill that can take place under external force can accurately reset after elastic deformation displacement and the external force elimination has been installed.The monodisplacement trigger switch element (comprising unidirectional mercury cut-off, optoelectronic switch, travel switch, microswitch) of in spring-backed quill, packing into, its sensing principle is: when rolling screen door is levered up, be located at rolling screen door bottom up postive stop baffle (have minority rolling screen door bottom do not weld up postive stop baffle then on this position with the bonding plate of epoxy resin for it) when moving up, spring-backed quill is lifted angle of rotation, make displacement switch connect and connect the warning circuit power supply and report to the police.Trigger switch rebounds along with sleeve pipe and resets, is in normally open when baffle plate continues up disengaging sleeve pipe.If then with telepilot the head that closes of the normal device of remote control relay in the warning circuit is opened earlier when owner will open rolling screen door, then can not reported to the police.Owner then places normally off with telepilot with the banked relay contact at closing time, allows warning circuit be in the warning waiting status.

The utility model beneficial effect is:

1. this sensor adaptive faculty is strong, can be installed in the door side on a various rolling screen door left side or right side, reports to the police too even the thief turns the key in the lock.

2. install simple, reliable, with low cost, install easy to adjustly, a few minutes are good and sound.

4. be positioned on an interior rear side owing to sensor, and the position is higher, the thief can't remove sensor or destroy it.

5. can not cause wrong report because of the vibrations of the careless collision of people or strong wind, Da Lei.
