Description

Technical Field

[0001] The present invention relates to the technical field of anti-theft doors, and in particular to an anti-theft door, a method for using an anti-theft door, and a production device for an anti-theft door. Background Art

[0002] An anti-theft door is a security door equipped with an anti-theft lock, which can resist abnormal opening under certain conditions within a certain period of time, and it has both anti-theft and security performance. With the advent of the intelligent era, in addition to unlocking with a mechanical key, the existing anti-theft doors also include intelligent unlocking methods such as fingerprint unlocking, face recognition unlocking, and sound wave unlocking. And the intelligent unlocking method must be realized through an electric control method. In order to be able to open the door even under power-off conditions, anti-theft doors are all equipped with a mechanical unlocking hole for mechanical unlocking when the power is off;

[0003] Due to the infrequent use of mechanical keys, they may be lost, and often go unnoticed when lost. Lawbreakers may use the mechanical key to commit theft or other illegal acts. Currently, as described in the Chinese patent CN217054910U, a storage compartment is added to the anti-theft door to place a spare key. However, the opening of the storage compartment is also through electric control, so the problem of opening the door under power-off conditions still cannot be solved. Therefore, adding a storage compartment to the anti-theft door cannot solve the problem of the loss of mechanical keys;

[0004] Therefore, there is a need for an anti-theft door that cannot be normally opened by lawbreakers even after they obtain the mechanical key after the mechanical key is lost. Summary of the Invention

[0005] The present invention aims at the deficiencies in the prior art and provides an anti-theft door, a method for using an anti-theft door, and a production device for an anti-theft door.

[0006] The existing anti-theft doors can be directly opened with a spare key, so lawbreakers can easily enter the user's home to commit illegal acts after obtaining the spare key. At the same time, the mechanical unlocking of the lock of the existing anti-theft door is integrated, and lawbreakers can directly imitate the spare key to open the anti-theft door through the unlocking operation.

[0007] To solve the above technical problems, the present invention is solved by the following technical solutions: An anti-theft door includes a door body, on which there is provided a spare key for locking an intelligent lock body and for unlocking. The intelligent lock body includes a first lock core and a second lock core. A blocking block that prevents the spare key from entering the second lock core is elastically and slidably arranged at the rear end of the first lock core. The blocking block is controlled by a pulling device to move away from or block the keyhole. The pulling device includes an electric control pulling unit. A signal transmitting unit and a video unit are arranged on the intelligent lock body. The spare key is inserted into the first lock core. The signal transmitting unit sends the confirmation unlocking information to the user's mobile terminal. At the same time, the video unit records a video of the unlocking person. After the user's mobile terminal confirms, the electric control pulling unit is activated, so that the spare key can be inserted into the second lock core to complete the unlocking.

[0008] The beneficial effects are as follows: When using the spare key to open the anti-theft door, when inserting the spare key, the intelligent lock body can automatically transmit the unlocking information and the information of the unlocker to the mobile terminal for the user to determine whether to unlock. At the same time, the first lock core cannot be used to open the anti-theft door, and the second lock core is blocked, thereby further improving the security of the anti-theft door.

[0009] In the above solution, preferably, the pulling device further includes a mechanical pulling unit. A plurality of decorative blocks are arranged on the door body, and at least one of the decorative blocks is elastically and slidably arranged on the main body in a limited way. Pressing the decorative block activates the mechanical pulling unit, so that the spare key can be inserted into the second lock core to complete the unlocking.

[0010] In the above solution, preferably, a locking block is arranged at the rear end of the decorative block. The locking block is controlled by the first lock core. Rotating the first lock core unlocks the locking block, and the decorative block can be pressed downwards.

[0011] In the above solution, preferably, the locking block includes a locking lock tongue that is elastically and slidably arranged at the rear end of the decorative block. One end of the locking lock tongue is connected to one end of a first pull rope, and the other end is connected to the first lock core. Rotating the first lock core winds the first pull rope to pull the locking lock tongue.

[0012] In the above solution, preferably, the first lock core rotates by at least 90 degrees to unlock the locking block. The decorative block for unlocking is randomly arranged among all the decorative blocks.

[0013] In the above solution, preferably, the mechanical pulling unit includes a pressing block that is elastically slidably arranged in the door body and a second pull rope with one end connected to the pressing block and the other end connected to the blocking block. The pressing block is located behind the decorative block.

[0014] A method for using an anti-theft door:

[0015] S1: Insert the spare key into the first lock cylinder. The signal transmitting unit sends a confirmation unlocking message to the user terminal, and the video unit records the physical characteristics of the person unlocking the lock.

[0016] S2: After the user terminal confirms, the electric control pulling unit in the intelligent lock body pulls the blocking block away from the keyhole, enabling the spare key to continue to be inserted into the second lock cylinder for unlocking.

[0017] In the above solution, preferably, a method for using an anti-theft door:

[0018] S1: Insert the spare key into the first lock cylinder;

[0019] S2: Rotate the spare key by a set number of turns, press the decorative block for unlocking known only to the user, and use the mechanical pulling unit to pull the blocking block away from the keyhole, enabling the spare key to continue to be inserted into the second lock cylinder for unlocking.

[0020] In the above solution, preferably, when the intelligent lock body is powered on, the mechanical pulling unit is used for unlocking, and the signal transmitting unit and the video unit operate simultaneously.

[0021] An anti-theft door production device includes a laser cutter. When batch cutting the plates used for processing the door body, according to the arrangement position of the decorative blocks, an installation hole at a different position is cut on each plate.

[0022] The beneficial effects of the present invention are as follows: The present invention provides an anti-theft door, a method for using an anti-theft door, and an anti-theft door production device. When using the spare key to open the anti-theft door, inserting the spare key causes the intelligent lock body to automatically transmit the unlocking information and the information of the person unlocking the lock to the mobile terminal. At the same time, the first lock cylinder cannot be used to open the anti-theft door, and the second lock cylinder is blocked. When the intelligent lock body is powered off or the user is disconnected, the entrance of the second lock cylinder is unlocked through a specific opening method, and then the spare key is used to open it, thereby further improving the security of the anti-theft door.

[0027] The present invention will be further described in detail below in conjunction with the drawings and the specific embodiments: Embodiment

[0028] Refer to Figures 1 - 4 , an anti-theft door, including a door body 1. A plurality of decorative blocks 11 are evenly arranged on the outer end face of the door body 1. One of the plurality of decorative blocks 11 is elastically guided and slidably arranged and can be pressed downward. And a locking block 12 is elastically guided and slidably arranged on the side of the sliding cavity of the elastically slidably arranged decorative block 11. The locking block 12 extends into the inner side wall of the sliding cavity and abuts against the rear end face of the decorative block 11, thereby locking the decorative block 11 so that it cannot be pressed backward. Therefore, when the locking block 12 is not removed, all the decorative blocks 11 are fixed and cannot move, so it is impossible for people to know in advance which decorative block 11 can be pressed.

[0029] The door body 1 is also provided with an intelligent lock body 2. The intelligent lock body 2 is provided with a fingerprint module, a video unit and a signal transmitting unit. The fingerprint module is used for fingerprint unlocking, the video unit is used for face recognition and video recording, and the signal transmitting unit is used for transmitting door opening and closing information to the user client and confirming unlocking when a spare key is inserted. After the door body 1 is installed in the user's home, the user sets the fingerprint and face information by himself. After the information recording is completed, the signal transmitting unit sends the specific position of the movable decorative block 11 to the user's mobile terminal, so that only the user knows the movable decorative block 11 of each door.

[0030] The intelligent lock body 2 includes a first lock core 21 and a second lock core 22. There is a blocking block 23 blocking between the first lock core 21 and the second lock core 22. The blocking block 23 is elastically guided and slidably arranged on the cross section of the lock hole. When the blocking block 23 extends out, it blocks the second lock core 22. When the user uses the spare key, the initial intelligent insertion is into the first lock core 21, and the first lock core 21 cannot be used to open the intelligent lock body 2. Only after the spare key is inserted into the second lock core 22 can the intelligent lock body 2 be opened. Due to the blocking of the blocking block 23, when an illegal element uses other tools to detect the lock hole information, only the information of the first lock hole can be detected, and the information of the second lock core 22 cannot be detected. And the blocking block 23 is controlled by a pulling device 24. The pulling device 24 includes an electric control pulling unit 241 and a mechanical pulling unit 242. The electric control pulling unit 241 includes a winding motor. One end of a third pulling rope is arranged on the winding motor, and the other end is connected to the rear end of the blocking block 23. When the winding motor starts, it can wind the third pulling rope, thereby pulling the blocking block 23 away from the lock hole position, so that the spare key can continue to be inserted into the second lock core 22.

[0031] A push switch is provided inside the first lock cylinder 21. After the user inserts the spare key into the first lock cylinder 21, the push switch is pressed, the video unit is activated to record the facial features of the person unlocking the door. At the same time, the signal transmitting unit sends the confirmation unlocking information and the photo or video of the person unlocking the door to the user's mobile terminal. After the user's mobile terminal confirms the unlocking information, the electric control pulling unit 241 pulls the blocking block 23 upward, enabling the spare key to be inserted into the second lock cylinder 22. At this time, the spare key is rotated to perform the unlocking operation.

[0032] Its working principle or usage method is as follows:

[0033] Method for unlocking a theft-proof door using a spare key:

[0034] After the spare key is inserted into the first lock cylinder 21, the signal transmitting unit sends the unlocking information and the facial features of the person unlocking the door recorded by the video unit to the user's mobile terminal. The user confirms unlocking or remotely locks it based on the information. After confirming unlocking, the electric control pulling unit 241 pulls the blocking block 23 away from the keyhole, enabling the spare key to be inserted into the second lock cylinder 22, and then rotated to unlock. Remote anti-locking is to control the intelligent lock body 2 to lock, and the spare key cannot be used to unlock again. It can only be opened after the user's mobile terminal is unlocked. Embodiment

[0035] Based on Embodiment 1, Embodiment 2 has further improvements, specifically:

[0036] See Figures 1 - 4 , a plurality of decorative blocks 11 are provided on the door body 1. When the plate of the door body 1 is cut by a laser cutting machine, according to the arrangement order of the decorative blocks 11, an installation hole is cut on each door body 1. An elastically guided and limitedly slidable decorative block 11 that can be pressed down is arranged on the installation hole, and it is fixed to the decorative block 11 in terms of position. A locking block 12 is provided at the rear end of the decorative block 11 that can be pressed and slid to block the downward sliding of the decorative block 11. The locking block 12 includes a locking tongue 121 and a first pull rope 122. A guiding sliding hole is opened on the side wall of the installation hole, and the locking tongue 121 is elastically guided and slidably arranged in the guiding sliding hole. A wire reel is provided on the first lock cylinder 21. One end of the first pull rope 122 is connected to the rear end of the locking tongue 121, and the other end is connected to the wire reel of the first lock cylinder 21. When the first lock cylinder 21 rotates, the first pull rope 122 is wound around the wire reel, thereby pulling the locking tongue 121 into the guiding sliding hole, eliminating the block at the rear end of the pressable decorative block 11. The mechanical pulling unit 242 includes a pressing block 2421 and a second pull rope 2422. The pressing block 2421 is elastically guided and slidably arranged on the bottom plate of the installation hole, and one end of the second pull rope 2422 is connected to the pressing block 2421, and the other end is connected to the blocking block 23.

[0037] After the user inserts the spare key into the first lock cylinder 21, the signal transmitting unit and the video unit are activated at this time. When the unlocking instruction is not obtained due to the user being busy or not paying attention, the electric control pulling unit 241 cannot move the blocking block 23 away. At this time, the mechanical pulling unit 242 can still be activated. At this time, turn the spare key half a turn or a multiple of half a turn, wind the first pulling rope 122 around the winding disc, so as to pull the locking lock tongue 121 away from below the decorative block 11, making the pressable decorative block 11 in the unlocked state. At this time, press the decorative block 11 to make it press against the pressing block 2421, and mechanically pull the pressing block 2421 away from the keyhole through the second pulling rope 2422. Setting the spare key to turn half a turn or a multiple of half a turn is to align the keyholes of the first lock cylinder 21 and the second lock cylinder 22 after using the spare key to turn the first lock cylinder 21 to unlock the decorative block 11, so that the spare key can be directly inserted into the second lock cylinder 22, and then turn the second lock cylinder 22 to unlock the door.

[0038] And how many turns the spare key needs to be turned after being inserted into the first lock cylinder 21 to move the locking lock tongue 121 away is only known to the user. At the same time, only the user knows the position of the movable decorative block 11. Therefore, under the uncertainty of these two, even if criminals get the spare key, they cannot open the anti-theft door, further ensuring the safety of the anti-theft door.

[0039] The production device for producing anti-theft doors includes a laser cutting machine. After the laser cutting machine cuts the steel plate for the anti-theft door at the conventional position, according to the cutting sequence number of the steel plate being cut and in accordance with the loading position of the decorative block 11, a mounting hole is cut on each steel plate. In this way, in the production of one batch, the number of mounting holes at the same position is small. Therefore, each decorative block 11 on the produced door body 1 may be pressable, further improving the safety of the anti-theft door.

[0040] Its working principle or usage method is as follows:

[0041] Method for opening the anti-theft door with a spare key:

[0042] After inserting the spare key into the first lock cylinder 21, the signal transmitting unit sends the unlocking information and the facial features of the unlocker recorded by the video unit to the user's mobile terminal at the same time. At this time, if the user does not confirm the operation in time due to problems, the unlocker can turn the spare key by the set number of turns, so that the locking lock tongue 121 behind the movable decorative block 11 is removed. The unlocker presses the movable decorative block 11, and through the mechanical pulling unit 242, pulls the blocking block 23 away from the keyhole, so that the spare key can be inserted into the second lock cylinder 22, and then rotated to unlock the door.

[0043] This method can also be used for emergency door opening when the intelligent lock body 2 is completely powered off.

[0044] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
