Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution:

the traditional anti-theft door basically depends on a cylindrical lock tongue after safety protection on the anti-theft function, and is basically provided with a safety-reinforced lock tongue structure, but under the normal condition, the concept of safety protection after door closing is not deep into the mind, so that thieves can take the anti-theft door with the lock tongue structure, steel plate materials like some anti-theft doors are thin, a prying bar is adopted to easily pry steel plates at the door lock 2 or the door frame 3, and the lock tongue is pried from the door groove 4, therefore, the integral anti-prying performance of the anti-theft door can be improved aiming at the safety plate arranged at the lock tongue, when other people forcibly open the door by adopting the prying bar, the area for prying the anti-theft door is increased, time and labor are wasted, and reinforcing bars are arranged on the door frame 3 and the anti-theft door, and the anti-prying performance of the anti-theft door is further improved;

when the cylindrical bolt is not opened, the door body 1 is closed, at this time, as shown in fig. 2, when the inclined bolt 6 on the door lock 2 contacts with the anti-theft mechanism 5 in the door frame 3, the inclined bolt 6 abuts against the touch switch 505 on the housing 501, so that the motor 502 located in the housing 501 starts to operate, it is emphasized that the inclined bolt 6 is freely telescopic, in order to prevent the inclined bolt 6 from colliding with the parts in the housing 501 to cause the anti-theft door to be unable to be closed, only the touch switch 505 is installed in the housing 501, and at the same time, the touch switch 505 does not affect the normal telescopic of the inclined bolt 6, when the inclined bolt 6 contacts with the touch switch 505, the motor 502 starts to operate, the baffle 503 in the housing 501 is rotated out, the baffle 503 abuts against the inclined bolt 6 on the door lock 2 to block both sides of the inclined bolt 6, when a thief starts to pick the lock, the baffle 503 blocks the inclined bolt 6 to cause the thief to directly to abut against the inclined bolt 6, meanwhile, the power supply of the motor 502 is provided by a battery arranged on the inner side of the door frame 3, and the battery is arranged in the power supply box 13, so that in order to prevent the problem of the power supply of the motor 502, when the power supply is short of electricity, an alarm is actively started to remind a resident of replacing the battery, and the situation that the antitheft door is locked and cannot work normally due to the fact that the battery is not electrified is avoided;

when the baffle 503 is normally abutted to the inclined bolt 6, the baffle 503 moving forward pulls the connecting rope 8 on the pulley 7 of the door frame 3, so that the rotating rod 9 at the other end of the connecting rope 8 moves towards the door frame 3, the rotating rod 9 rotates and simultaneously sends the clamping rod 11 into the clamping groove 12 on the door body 1, the clamping rod 11 is made of medium carbon quenched and tempered steel, the hardness is high, the abrasion resistance is strong, when the clamping rod 11 is blocked above the door lock 2, and the anti-theft door is forcibly pried, the area of the pried door frame 3 is increased, and the clamping rod 11 needs to be cut off, so that the safety performance of the anti-theft door is further improved;

when the bolt is moved out of the casing 501, the touch switch 505 drives the motor 502 to rotate reversely to transfer the baffle 503 back from the through groove 504, the spring 10 pulls the rotating rod 9 to pull the clamping rod 11 out of the clamping groove 12, the door body 1 is opened from the door frame 3, the operations are repeated, the forward and reverse rotation of the motor 502 is regulated by the touch switch 505, meanwhile, a touch signal of the touch switch 505 is processed by a simple single chip microcomputer and then fed back to the motor 502, and the forward and reverse rotation of the motor 502 is controlled by simply controlling the electrodes of the power supply.

The utility model discloses a working process:

when the door begins to be closed, the cylindrical bolt on the door lock 2 is not opened, when the door body 1 is closed, the inclined bolt 6 on the door lock 2 abuts against the shell 501 in the door slot 4, the inclined bolt 6 triggers the touch switch 505 in the shell 501, so that the motor 502 in the shell 501 starts to work, the motor 502 rotates to rotate the whole baffle 503 out of the through slot 504, so that the baffle 503 abuts against the inclined bolt 6, when the baffle 503 normally abuts against the inclined bolt 6, the forward moving baffle 503 pulls the connecting rope 8 on the pulley 7 of the door frame 3, so that the rotating rod 9 at the other end of the connecting rope 8 moves towards the door frame 3, and the clamping rod 11 is sent into the clamping slot 12 on the door body 1 while the rotating rod 9 rotates;

when the door body 1 is opened and the latch bolt is moved out of the shell 501, the touch switch 505 drives the motor 502 to rotate reversely to transfer the baffle 503 from the through groove 504, and the spring 10 pulls the rotating rod 9 to pull the clamping rod 11 out of the clamping groove 12;

additionally, in order to prevent the motor 502 from being unable to be normally opened due to the power source, the resident needs to pay attention to the power source alarm signal on the security door and timely replace the power source.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
