Description

Invisible anti-theft net convenient to install

Technical Field

The invention belongs to the technical field of security and protection facilities, and particularly relates to an invisible anti-theft net convenient to install.

Background

The invisible anti-theft net is used for protecting and preventing objects from falling and is not invisible, a 2MM thick steel wire is tensioned and wound between the profiles fixed at the outer end of the window, the spacing between the steel wires is fixed to be 5CM, the steel wire can bear the tension above 85-120KG, the situation that a thief cannot break can be guaranteed, and the spacing between the steel wires is 5CM, so that a person cannot drill into the invisible anti-theft net from a gap, and the anti-theft protection effect can be effectively achieved.

The invisible anti-theft net is specially designed with a steel wire shearing alarm function, when a thief shears a steel wire, an intelligent alarm connected with the steel wire sends out an alarm signal, and the alarm is carried out in two ways, namely, firstly, sound alarm is carried out, and when the alarm is given out, a 120-decibel sharp whistle is sent out, so that the thief can be effectively scared. Meanwhile, the alarm host can automatically start the dialing alarm function and can continuously dial 7 preset groups of numbers (such as property security, owner mobile phones, office phones and the like). After the alarm is switched on, the alarm content recorded by the owner in advance can be played. Therefore, the protection system can ensure the safety of the living room. The other purpose of the functional design is to meet the requirements of the fire department, and when a fire disaster happens in a house, the steel wire can be cut off automatically, and the window can be used for escaping rapidly.

An invisible anti-theft net with patent number 201420046672.1 comprises an upper bracket, a lower bracket, a single screw, a double screw and 2 steel wires, wherein the upper bracket and the lower bracket are arranged in parallel, the upper bracket and the lower bracket are both provided with the single screw and the double screw, the sequence of the upper bracket for the single screw and the double screw is that 1 group of the single screw follows 1 group of the double screw and then 1 group of the single screw reciprocates in turn, the sequence of the corresponding lower bracket for the single screw and the double screw is that 1 group of the double screw follows 1 group of the single screw and then 1 group of the double screw reciprocates in turn, 1 group of the single screw is 2 single screws, 1 group of the double screws is 2 double screws, the position of the upper bracket for the single screw is correspondingly arranged on the lower bracket as the double screw, the distances between the single screw and the double screw, the single screw and the double screw are kept consistent, the steel wire 1 winds the upper support and the lower support in sequence from one end of the upper support and keeps in a tight state, and the steel wire 1 winds the lower support and the upper support in sequence from one end of the lower support and keeps in a tight state.

Above technical scheme though can play the effect of theftproof, when the installation, need twine two steel wires on upper bracket and lower carriage in proper order, work load is big, and the installation is troublesome to in case two steel wires all break or relax, will lead to whole anti-theft net to lose effect, it is very troublesome to change the steel wire.
