Technical Field

[0001] The invention relates to an industrial electronic lock, in particular to a high-protection self-resetting controlled industrial electronic lock. Background Art

[0002] Industrial electronic locks refer to electronic locks used in industrial production and commercial applications. They are mainly used in smart self-service terminals, personal computers, transportation, storage equipment, power transmission and distribution, etc. They are divided into key locks, fingerprint locks, RFID locks, Bluetooth locks, etc. The mechanical lock cores of existing traditional industrial electronic locks are generally universal. As long as they are the same lock cores, they can be opened, and their security and anti-theft effects are poor. Existing optical delivery box smart locks for mobile communication devices, such as the application number 201910043189.5 disclosed in Chinese patent documents, the authorization announcement date is 2021.04.09, and the utility model name is "universal optical delivery box smart lock"; existing industrial smart locks, such as the application number 201920624729.4 disclosed in Chinese patent documents, the authorization announcement date is 2020.04.07, and the utility model name is "industrial anti-pry smart lock"; but the above products and similar products have poor linkage control between the handle lock tongue and the solenoid valve core, and lack the base lock tongue structure design and participation. To this end, as disclosed in the Chinese patent literature, application number 201811472799.9, application publication date 2019.03.01, invention name "Lock core controlled industrial smart lock"; however, the controlled structure design of the above-mentioned product and similar products is relatively complex, production and assembly are relatively inconvenient, and the production cost is relatively high; at the same time, its waterproofness generally only has ordinary IP65 waterproof and rust-proof functions, and it is difficult to meet high requirements for waterproofness, and its waterproof performance and waterproof structure need to be improved and perfected. Summary of the invention

[0003] In order to overcome the above shortcomings, the purpose of the present invention is to provide a high-protection self-reset controlled industrial electronic lock to the art, so as to solve the technical problems of the existing similar products, such as poor controlled and waterproof structure design, lack of linkage structure design between base lock tongue, handle lock tongue and valve core of solenoid valve, and glue filling and module structure design. The purpose is achieved through the following technical solutions.

[0004] A high-protection self-reset controlled industrial electronic lock, a handle is provided in a handle groove at the base of the industrial electronic lock, a rotating shaft hingedly arranged at one end of the handle extends out of the bottom of the base and is connected to an actuator, a handle lock tongue at the bottom of the lock core at the other end of the handle is locked in the lock core groove of the base, and a solenoid valve, a PCBA circuit board and a base lock tongue are arranged in the base; the key point of its structural design is that the handle lock tongue is locked in the lock core groove of the base through the solenoid valve, one end of the valve core of the solenoid valve in the base extends into the lock core groove of the base to limit and abut the handle lock tongue of the handle, and at the same time, the The valve core is inserted into the lock hole of the handle lock tongue of the handle, one end of the base lock tongue in the base below the valve core is against the protruding end of the handle lock tongue, the handle lock tongue supports the base lock tongue and moves axially with the valve core, and the other end of the base lock tongue in the base is driven by the handle lock tongue to align below the micro switch, and when the solenoid valve is powered on and controlled, this end of the base lock tongue triggers the micro switch, and a spring for resetting is provided in the base lock tongue. The valve core and the base lock tongue of the solenoid valve push the handle lock tongue to reset and maintain the locked state; the solenoid valve is a self-holding solenoid valve. Therefore, when the industrial electronic lock is powered on and a mechanical key is used to unlock it, the handle lock tongue presses against the base lock tongue and moves axially with the valve core. When the base lock tongue triggers the micro switch, the solenoid valve unlocks and the valve core is released immediately, so that the mechanical key cannot unlock the lock and the lock core is controlled. When the valve core of the solenoid valve is separated from the handle lock tongue limit and exits the lock hole of the handle, it can be completely separated from the handle, and the handle can be ejected from the base for use. When the key is inserted to drive the lock core to rotate, the lock core drives the handle lock tongue to press against the base lock tongue and move axially with the valve core. The limiting and abutting structure between the valve core and the handle lock tongue of the above-mentioned solenoid valve mainly adopts a side groove structure, that is, the valve core of the solenoid valve is limited and abuts against the side groove at one end of the handle lock tongue; the attraction and release of the above-mentioned solenoid valve are realized according to the positive and negative power supply.

[0005] When the solenoid valve is powered on, the solenoid valve is pressed by the handle to trigger the valve core of the solenoid valve to be attracted. A wake-up button for triggering the solenoid valve is provided on the handle or a trigger button is provided in the handle groove of the base.

[0006] The shaft hole of the handle lock tongue is inserted into the eccentric positioning shaft at the bottom of the lock core, and a torsion spring is provided at the hinge of the handle and the rotating shaft; when the solenoid valve is powered off and the lock core rotates 180°, the valve core of the solenoid valve moves to the suction position, the lock core is released, the handle is pressed, the valve core of the solenoid valve is separated from the lock hole and the handle lock tongue, and the base lock tongue drives the handle lock tongue to reset through the spring, and the handle pops out of the base. In the above-mentioned eccentric lock core, when the lock core rotates 180°, the handle lock tongue pushes the base lock tongue to move forward, the spring at the base lock tongue will be compressed, and the key that rotates the lock core is released. Under the action of the spring force, the lock core will be reset immediately, that is, the lock core and the handle lock tongue are reset through the base lock tongue and the spring, and the lock core rotates to the unlocking position. At this time, the handle is pressed, and the handle pops out of the base under the action of the torsion spring to complete the unlocking operation. The above-mentioned is a mechanical key unlocking method, and it is better to use the existing inclined surface form at the side groove of the handle lock tongue.

[0007] The spring is arranged in the middle spring slot in the base lock tongue, one end of the spring abuts against the inner wall of the spring slot, and the other end of the spring abuts against the spring column protruding from the module housing or the base.

[0008] The two ends of the base lock tongue are respectively tilted in a "[" shape, and the tilted side of the base lock tongue and the spring are arranged in the slide groove at the bottom of the module shell. The solenoid valve is arranged in the module shell below the slide groove, and one end of the valve core of the solenoid valve extends out of one side of the module shell.

[0009] The switch hole and the wire outlet hole of the module housing, and the connection between the module housing and one side of the bottom of the PCBA circuit board are encapsulated as a whole by glue potting to form a waterproof mechanism module.

[0010] The micro switch at the switch hole of the module housing is arranged on the PCBA circuit board, the micro switch at the PCBA circuit board is provided with a glue seal, and the reed of the micro switch extends out of the switch hole of the module housing.

[0011] The other side of the top of the PCBA circuit board is encapsulated in the base partition at the handle groove of the base below the handle by glue pouring. The above structure is not limited to the base partition method of encapsulating the glue-filled PCBA circuit board, and the base partition can also be omitted, and the PCBA circuit board is loaded and encapsulated through the bottom of the base.

[0012] A glue-filled seal is provided in the hole at the lead-out line extending out of the base at the bottom or one side of the PCBA circuit board.

[0013] The lead wire is fixed to the lead hole on one side of the base or module housing through a wire sleeve, so that the lead wire adopts a "X"-shaped anti-pullout design, and the lead wire is fixed to the lead hole of the base or module housing through the wire sleeve to prevent pullout.

When the solenoid valve is powered on, the solenoid valve is triggered by the handle to press the valve core of the solenoid valve, and a wake-up button for triggering the solenoid valve is provided on the handle or a trigger button is provided in the handle groove of the base.

[0027] The shaft hole of the handle lock tongue is inserted into the eccentric positioning shaft at the bottom of the lock core, and a torsion spring is provided at the hinge of the handle and the rotating shaft; when the solenoid valve is powered off and the lock core rotates 180°, the valve core of the solenoid valve moves to the suction position, the lock core is released, the handle is pressed, and the valve core of the solenoid valve is separated from the lock hole and the handle lock tongue. At the same time, the base lock tongue drives the handle lock tongue to reset through the spring, and the handle pops out of the base. The spring is arranged in the spring groove in the middle of the base lock tongue, one end of the spring is against the inner wall of the spring groove, and the other end of the spring is against the spring column 1201 protruding at the module shell 12 or protruding in the base.

When the handle is pressed, the valve core of the self-holding solenoid valve will be attracted. When the handle is released, the handle will pop up automatically. When the handle pops up, the base lock tongue will push the valve core of the self-holding solenoid valve back to the closed position under the action of the spring force.

[0031] Function three (mechanical lock core controlled): When the industrial electronic lock is powered on, use the mechanical key to unlock it, the handle lock tongue presses against the base lock tongue and moves axially with the valve core. When the base lock tongue triggers the micro switch, the self-holding solenoid valve unlocks and the valve core of the self-holding solenoid valve is immediately released. The valve core of the self-holding solenoid valve follows the handle lock tongue to return to the locked state, thereby achieving the purpose of the mechanical key being unable to unlock the lock.
