A high-protection, self-resetting, controlled industrial electronic lock

Abstract

The present invention relates to a high-security, self-reset, controlled industrial electronic lock. This lock addresses the technical issues of existing similar products, which suffer from poor controllable and waterproof structural designs and a lack of a linkage structure between the base lock tongue, handle lock tongue, and valve core of a solenoid valve. The key features of this industrial electronic lock are that the handle lock tongue is locked to a lock core groove in the base via a solenoid valve. One end of the solenoid valve core in the base extends into the base lock core groove to limit its position and abut against the handle lock tongue of the handle. Simultaneously, the valve core is inserted into a lock hole in the handle lock tongue of the handle. One end of the base lock tongue in the base below the valve core abuts against the extended end of the handle lock tongue. The handle lock tongue presses against the base lock tongue and moves axially with the valve core. The other end of the base lock tongue, driven by the handle lock tongue, moves to align below a microswitch. When the solenoid valve is energized and controlled, this end of the base lock tongue triggers the microswitch. A spring is provided within the base lock tongue for resetting, and the solenoid valve core and base lock tongue push the handle lock tongue back to its original position, maintaining the locked state.

Description

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 primarily used in smart self-service terminals, personal computers, vehicles, storage equipment, and power transmission and distribution. They are categorized as keypad locks, fingerprint locks, RFID locks, and Bluetooth locks. The mechanical lock cylinders of existing traditional industrial electronic locks are generally universal, meaning any lock cylinder can be opened without any other lock cylinder, resulting in poor security and theft prevention. Existing optical delivery box smart locks for mobile communication devices, such as application number 201910043189.5, disclosed in Chinese patent literature, with a grant date of April 9, 2021, and the utility model title "Universal Optical Delivery Box Smart Lock," and existing industrial smart locks, such as application number 201920624729.4, disclosed in Chinese patent literature, with a grant date of April 7, 2020, and the utility model title "Industrial Anti-theft Smart Lock," suffer from poor linkage control between the handle lock tongue and the solenoid valve core, and lack the structural design and integration of the base lock tongue. For this reason, as disclosed in the Chinese patent literature, application number 201811472799.9, application publication date 2019.03.01, and invention name "Lock cylinder 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] To overcome the aforementioned shortcomings, the present invention aims to provide a highly secure, self-resetting, controlled industrial electronic lock. This lock addresses the technical issues of existing similar products, such as the suboptimal control and waterproof design, the lack of a linkage design between the base and handle lock tongues and the solenoid valve core, and the lack of glue potting and module design. This objective is achieved through the following technical solutions.

[0004] A high-protection self-reset controlled industrial electronic lock, which has a handle in the handle groove at the base, a hinged shaft at one end of the handle extending out of the bottom of the base to connect to the 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 provided 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, The valve core is inserted into the lock hole of the handle lock tongue of the handle, and 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 presses the base lock tongue and moves axially with the valve core. 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 energized 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 microswitch, the solenoid valve unlocks and the valve core is immediately released, thereby preventing the mechanical key from unlocking the lock and achieving control of the lock core. Only when the solenoid valve core is free from the handle lock tongue limit and exits the handle lock hole can it be completely separated from the handle and the handle can be ejected from the base for use. When the key is inserted and the lock core rotates, 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 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 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 handle lock tongue's axial hole is inserted into the eccentric positioning shaft at the bottom of the lock core, and a torsion spring is provided at the hinged connection between the handle and the rotating shaft. When the solenoid valve is powered off and the lock core rotates 180°, the solenoid valve's valve core moves to the engaged position. The lock core is released, the handle is pressed, and the solenoid valve's valve core disengages from the lock hole and the handle lock tongue. At the same time, the base lock tongue drives the handle lock tongue back to its original position via the spring, and the handle pops out of the base. With the eccentric lock core described above, when the lock core rotates 180°, the handle lock tongue pushes the base lock tongue forward, compressing the spring at the base lock tongue. When the key is released and the lock core is rotated, the lock core is immediately reset under the action of the spring force. That is, the lock core and handle lock tongue are reset through the base lock tongue and the spring. The lock core rotates to the unlocked position. At this point, pressing the handle causes the handle to pop out of the base under the action of the torsion spring, completing the unlocking operation. The above is a mechanical key unlocking method, and it is preferable 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 groove in 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 raised on the module shell 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 is potted and encapsulated in the base partition at the handle groove of the base below the handle. The above structure is not limited to the base partition method of encapsulating the potted PCBA circuit board. The base partition can also be omitted. The PCBA circuit board is installed and potted 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 wire outlet hole on one side of the base or module housing through a wire sleeve. Thus, the lead wire adopts an X-shaped anti-pullout design, and the lead wire is fixed to the wire outlet hole of the base or module housing through the wire sleeve to prevent it from being pulled out.

[0014] The present invention has a reasonable structural design, convenient production and assembly, low production cost, good stability, good waterproof effect, high waterproof level, long service life, and is convenient for remote monitoring, management and control; it is suitable for use as a high-protection self-resetting controlled industrial electronic lock, as well as a structural improvement of similar products.

[0026] Now, the structure of the present invention will be further described in conjunction with the accompanying drawings. Figures 1-10As shown, a high-protection self-reset controlled industrial electronic lock is provided. A handle 10 is provided in a handle groove at a base 9 of the industrial electronic lock. A rotating shaft hinged at one end of the handle extends out of the bottom of the base and is connected to the actuator. A torsion spring is provided at the hinged joint between the handle and the rotating shaft. A handle lock tongue 1 at the bottom of the lock core 11 at the other end of the handle is locked to the lock core groove of the base. A solenoid valve 2, a PCBA circuit board 4 and a base lock tongue 7 are provided in the base; the handle lock tongue is locked to the lock core groove of the base through the solenoid valve 2, and one end of the valve core 201 of the solenoid valve in the base extends into the lock core groove of the base to limit and resist the handle of the handle. At the same time as the handle lock tongue, 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 abuts against the protruding end of the handle lock tongue. The handle lock tongue presses against the base lock tongue and moves axially with the valve core. The other end of the base lock tongue in the base is driven by the handle lock tongue to align below the micro switch 3. When the solenoid valve is energized and controlled, this end of the base lock tongue triggers the micro switch. A spring 8 for resetting is provided in the base lock tongue. The valve core of the solenoid valve and the base lock tongue push the handle lock tongue to reset and maintain the locked state. The solenoid valve is a self-holding solenoid valve. When the solenoid valve is energized, the solenoid valve is triggered by the handle pressing the solenoid valve core to attract. 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 handle lock tongue's axial hole is inserted into an eccentric positioning shaft at the bottom of the lock core, and a torsion spring is installed at the hinged connection between the handle and the rotating shaft. When the solenoid valve is de-energized and the lock core rotates 180°, the solenoid valve's valve core moves to the engaged position. The lock core is released, and the handle is pressed. Simultaneously, the solenoid valve's valve core disengages from the lock hole and handle lock tongue. The base lock tongue, driven by the spring, resets the handle lock tongue, and the handle pops out of the base. The spring is located in a spring groove in the center of the base lock tongue. One end of the spring abuts against the inner wall of the spring groove, while the other end abuts against a protrusion on the module housing 12 or a spring column 1201 protruding from the base. The base lock tongue is tilted at both ends to form a "[" shape. The tilted side of the base lock tongue and the spring are located in a slide groove at the bottom of the module housing. The solenoid valve is located in the module housing below the slide groove, and one end of the solenoid valve's valve core protrudes from one side of the module housing.

[0028] The switch hole 1202 and wire outlet hole 1203 of the module housing, as well as the connection between the module housing and the bottom side of the PCBA circuit board, are encapsulated by glue to form a waterproof mechanism module. Specifically, a microswitch is installed on the PCBA circuit board at the switch hole of the module housing. The microswitch on the PCBA circuit board is sealed with glue, and the reed of the microswitch extends out of the switch hole of the module housing. The other side of the top of the PCBA circuit board is encapsulated by glue within the base partition in the handle groove of the base below the handle. The lead wire 6 extending from the base at the bottom or one side of the PCBA circuit board is sealed with glue. The lead wire is fixed to the base through a wire sleeve 601 and extends out of the wire outlet hole of the module housing. In the embodiment of the above-mentioned actuator, the actuator adopts a connecting rod assembly. The rotating shaft extending from the bottom of the base engages with the teeth of the connecting rods on both sides of the connecting rod assembly through a gear. The bottom of the base is provided with a pressure plate and a wire clip.

[0029] The specific working process of the three major functions of the industrial electronic lock is described as follows:

[0030] Function 1 (mechanical key unlocking): When the industrial electronic lock is powered off, use the mechanical key to rotate the lock cylinder on the handle clockwise. At this time, the handle lock tongue presses against the base lock tongue and moves axially with the valve core. When the lock cylinder rotates 180° and reaches the position where the self-holding solenoid valve is attracted, release the key and press the handle. The lock cylinder automatically resets and the handle automatically pops up. When the handle pops up, the base lock tongue pushes the valve core back to the closed position under the action of the spring force.

[0031] Function 2 (DO unlock): When the DO unlock command is received, the self-holding solenoid valve is activated and energized. When the handle is pressed, the valve core of the self-holding solenoid valve is attracted. When the handle is released, the handle automatically pops up. When the handle pops up, the base lock tongue pushes the valve core of the self-holding solenoid valve back to the closed lock position under the action of the spring force.

[0032] 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 preventing the mechanical key from unlocking.

[0033] To summarize, the industrial electronic lock involves a lock mechanism with a controlled lock cylinder. It is a high-protection, self-reset unlocking, and lock cylinder-controlled industrial electronic lock. In order to ensure the operation and management of equipment and facilities as well as the safety of people and property, it is designed according to the need for mechanical lock cylinder control. It is a lock that controls the lock cylinder when power is on.
