The invention discloses a mobile terminal and an unlocking method thereof. The mobile terminal sets an unlocking expression, and the unlocking expression comprises at least one variable. The unlocking method includes steps that extracting all the variables in the unlocking expression when the mobile terminal is located at a locked state and receives an unlocking command; randomly assigning each variable; displaying the value of each variable and a password entry box; after the password entry box receives an input value as a password, calculating the correct result value of the unlocking expression according to the value of each variable, judging whether the input value is equal to the correct result value, if so, unlocking the mobile terminal; otherwise, enabling the mobile terminal to continue to randomly assign each variable. The unlocking method unlocks the mobile terminal through setting the unlocking expression, the unlocking difficulty is increased, the other people are difficult to decode the unlocking mode of the mobile terminal, and the universality of the mobile terminal unlocking mode is reinforced.

The invention discloses a method and system for achieving mobile terminal screen unlocking through matching of retina information. The method includes the steps that first retina information used for screen unlocking is stored in a mobile terminal; communication connection is built between retina reading equipment and the mobile terminal; the retina reading equipment reads second retina information and transmits the second retina information to the mobile terminal; the mobile terminal receives the second retina information and enables the second retina information and the first retina information to be matched; after matching is successfully carried out, a screen unlocking instruction is generated and a mobile terminal screen is unlocked. Unlocking difficulty of the mobile terminal is increased, personal information is safer, connection can be built as long as the retina reading equipment and the mobile terminal are within a set range, and accordingly unlocking can be achieved after a user puts the mobile terminal in front of himself, the method and system are easy and convenient to use, and only the user himself can unlock in the way.

The invention discloses a transformer with an anti-theft alarm function, and the transformer is fixedly arranged at the bottom of a containing cavity; a lock cylinder is rotationally connected into a lock hole, one end of the lock cylinder extends into a control cavity and is fixedly connected with a first rotating gear, a first push rod is slidably arranged in a first push rod cavity, and a second push rod is slidably arranged in a second push rod cavity. The electromagnet is embedded above the first push rod cavity, the positioning rod is slidably arranged in the positioning hole, the closing mechanism is fixedly arranged in the transmission cavity, the baffle is slidably arranged in the baffle cavity and fixedly connected with the closing mechanism, the Bluetooth module is embedded in the inner side of the door plate, the pressure switch is fixedly arranged on the top wall of the transmission cavity, and the alarm mechanism is fixedly arranged on the top of the anti-theft shell. The second push rod is completely sucked into the second push rod cavity through the electromagnet, so a thief cannot unlock the lock by shifting the push rod, the anti-theft effect is achieved, and when the thief pries the baffle plate forcibly, the pressure switch is triggered, the alarm mechanism is started, and the aim of frightening the thief is achieved.

A tubular lock has a casing, a key pin seat, a driving pin seat, at least one positioning assembly, a side pin seat, at least one side positioning assembly and a fastening assembly. The positioning assembly is mounted axially in the key pin seat and is mounted through the driving pin seat. The side positioning assembly is mounted transversely through the casing and the side pin seat. With the installation of the side positioning assembly, the tubular lock can increase the permutation combinations of all the positioning assemblies. With the positioning assembly and the side positioning assembly operating in perpendicular directions to each other, the tubular lock can increase the difficulty of unlocking. With the both features, the tubular lock can enhance safety.

The invention discloses a safety cabinet which cannot be carried away or prized up but can send an alarm. The safety cabinet consists of a cabinet body (1) and a cabinet door (2), wherein the cabinet door (2) is provided with a latch structure for realizing opening and closing with the cabinet body (1) and a coded lock for controlling opening of the latch; a bottom plate (9) of the cabinet body (1) is provided with a ground screw hole (10); a rear box plate (7) of the cabinet body (1) is provided with a wall screw hole (8); and the cabinet body (1) is fixed with the ground and the wall through the ground screw hole (10) and the wall screw hole (8) by using a ground screw (11) and a wall screw (12). The safety cabinet is a real safety cabinet which cannot be carried away, prized up or opened without password.

The invention relates to a disassembly-prevention exhaust lock valve comprising a needle type exhaust valve and a composite lock. The disassembly-prevention exhaust lock valve is characterized in that the composite lock is composed of a disassembly-prevention cover, an anti-theft lock arranged in the upper portion of the disassembly-prevention cover, a key matched with the anti-theft lock, and a seal sheet; a transverse insertion cavity corresponding to a lateral opening of the needle type exhaust valve is formed in the lower portion of the disassembly-prevention cover; a longitudinal through hole communicating with the upper portion of the disassembly-prevention cover is formed in the top of the transverse insertion cavity; a lock pin moving along the longitudinal through hole is arranged on the bottom face of a lock cylinder of the anti-theft lock; an inclined arc U-shaped groove is formed in the peripheral face of the lock cylinder; a positioning pin and a positioning spring which correspond to the inclined arc U-shaped groove are arranged on the inner circumferential face of a lock body of the anti-theft lock; an annular lock groove is formed in the front end of a valve body of the needle type exhaust valve; and after the needle type exhaust valve is inserted in the transverse cavity, the tail end of the lock pin is clamped in the annular lock groove of the needle type exhaust valve. By means of the disassembly-prevention exhaust lock valve, hot water in a pipe network is prevented from being lost; and compared with an existing combined exhaust lock valve, the unlocking difficulty is increased, the size is reduced, and the application range is wide.

The embodiment of the invention discloses a seal opening method and system. The seal can be provided with a lock module, and the lock module can be used for locking the seal. The seal opening method can comprise the steps: scanning and recognizing an identification code of a product with a to-be-opened seal through a terminal; after the identification code is successfully identified, sending an identification effective instruction is sent through a near field communication (NFC) function in the terminal; and obtaining the identification effective instruction through an NFC module arranged on the product, and controlling the lock module to perform unlocking according to the identification effective instruction so as to open the seal. According to the scheme of the embodiment, the identification code of the product and the NFC module arranged on the product are combined, and the lock module at the seal is jointly unlocked, so that the unlocking difficulty is improved, the imitation cost of the product where the seal is located is correspondingly improved, the anti-counterfeiting effect of the product is enhanced, and the protection strength of the product is improved.
