Abstract
A rolling screen door magnet with function of preventing external magnetic field interference comprises a base whose inner is provided with tongue tubes, and a magnet, wherein four tongue tubes which are mutually crossed and a return circuit resistance R are installed in the base, two tongue tubes located on the left side and the right side are connected to an alarm host machine after being connected with each other in parallel, and one ends of the tongue tubes located in the middle are connected to the alarm host machine after being connected to the return circuit resistance R after being mutually connected in parallel. The door magnet has the advantages of strong functions, stable performance self protection, convenient installation, simple use and the like, and prevents strong magnetic interference.
Description
Technical field
The utility model relates to the separation of objects such as door, window and the monitoring device of closed condition, particularly has magnetic patch--the dry-reed safe antitheft monitoring device that anti-strong magnetic disturbance destroys function.
Background technology
Along with the development of society, the progress of science and technology, the raising of living standards of the people, people pay attention to cultural life more when paying attention to material life.The raising of security protection consciousness, higher to the performance requirement of security product, more perfect, this has promoted the development of security protection industry to a great extent.Be subjected to deeply to have obtained innovation and development on the basis of the also former common door magnetic of rolling door magnetic that businessman likes.
The base the inside of common rolling door magnetic has only a tongue tube, limited with the contact area of magnetic patch, magnetic patch is an integral body of fixing, can not shrink, there is not ductility, because the unreasonable and defective that self designs of installing causes effective distance that contacts of magnetic patch and base to diminish, and many times can produce the situation of wrong report.
This rolling door magnetic is on the basis of common rolling door magnetic, improves, innovation, design, a plurality of tongue tubes and a resistance, the tongue tube that staggers mutually in front and back are contained in the base the inside, can increase the width of contact, thereby the increase contact area, if one of them damages, other tongue tube can also work on, stablize the performance of door magnetic, prolonged service life.About the tongue tube of opposition can prevent the interference of high-intensity magnetic field, if having high-intensity magnetic field near and influence, circuit will be connected, and reports to the police.The shell of magnetic patch adopts telescopic material, when installing, generally all is that magnetic patch is installed on the door eaves of rolling door, because the door eaves is a metal, can eliminate part magnetic force, thereby weaken the coverage that magnetic patch contacts with base, the general coverage of door magnetic has 5～6cm, after installing, has only 2～3cm, what have has only 1～2cm, and in blowing, rolling door can be moved, the tongue tube that just may cause connection disconnects, and alarm host machine will false alarm.
The utility model content
The purpose of this utility model provides a kind of rolling door magnetic with anti-extraneous high-intensity magnetic field interference function of highly sensitive, good reliability.
This novel purpose is achieved in that a kind of rolling door magnetic with anti-extraneous high-intensity magnetic field interference function, comprises the base that tongue tube is installed in it, and magnetic patch has a plurality of tongue tubes that stagger mutually and install in the base.
4 tongue tubes and a loop resistance R are installed in the above-mentioned base: two tongue tubes back parallel with one another that is positioned at and arranged on left and right sides is used as behind the end serial connection loop resistance R after two tongue tube parallel connections in the middle of being positioned at and is connected to alarm host machine as being connected to alarm host machine.
The utility model is made up of the magnetic patch that is fixed on base on the ground and be installed on the rolling door, a plurality of tongue tubes are contained in base inside. and magnetic patch is made up of inner magnet and flexible shell. and it is realized by following design, the tongue tube of base is a kind of special key of magnetosensitive. its two contacts are made by special material, be encapsulated in the glass tube of vacuum. as long as use magnet near it, two nodes of tongue tube will be pulled together, making circuit turn-on. the tongue tube of base mainly is arranged as and is parallel to each other and staggers, effectively increased the contact area of base and magnetic patch, help improving the on-state rate of circuit, the use of convenient businessman. the tongue tube that opposes mutually about on the base, can prevent the interference of outside high-intensity magnetic field. when the tongue tube that plays a major role, be in closed conducting state, when having outside high-intensity magnetic field close, the tongue tube of both sides meeting conducting in addition, thereby can alarm. magnetic patch is installed on the rolling door, there is magnet magnetic patch inside, when closing the door, magnetic patch contacts with base, the tongue tube closure, circuit turn-on, if this magnetic is inserted alarm host machine, and be in the state of deploying troops on garrison duty, when the external world have high-intensity magnetic field near or door when being opened, alarm host machine will be sent alarm signal, alert will be known in user and the center of receiving a crime report, and in time handles.
Compare with existing rolling door magnetic, this magnetic has following superiority:
1, magnetic patch control gap distance is big
The tongue tube quantity of base increases, and in perfect order during function is distributed separately, and the tongue tube that plays a major role is parallel to each other and the placement of staggering, and the effective like this contact area that has increased base and magnetic patch can increase effectiveness.In addition, if one of them damage can also work on.Can prolong the application life of base.
2, anti-strong magnetic disturbance
The parallel tongue tube in the left and right sides can prevent the influence of extraneous high-intensity magnetic field to base.When extraneous high-intensity magnetic field is close, the reed switch conduction of the left and right sides, the alarm host machine of joining with it can be sent alarm signal, notice businessman and alarm center.General rolling door magnetic base, the inside has only a tongue tube, under the closure state, under the influence of external magnetic field, opens rolling door, and alarm host machine can't be reported to the police, and causes the robber to have an opportunity to take advantage of.
3, reliability height
The shell of magnetic patch adopts telescopic material to make, and prevents when installing, and causes the magnetic force loss, brings distance of reaction to reduce, thus the situation of false alarm.Scalable shell can extend the magnet segment of magnetic patch the door eaves of rolling door, can not lose distance of reaction.
4, simple in structure, easy for installation, easy to use.
