The two arc-shaped elastic plates 424 are arranged around the lock shaft 421 and are staggered in an upper and lower manner. The elliptical rotating plate 40 is rotatably mounted on the lock shaft 421 through a rotating shaft 428, that is, the rotating shaft 428 passes through a central through hole at the center of the lock shaft 421, so that the rotating shaft 428 can rotate. The inner walls of both ends of the elliptical rotating plate 40 are respectively provided with rollers 401, and each roller 401 respectively contacts the inner wall of the outer end of the two arc-shaped elastic plates 424. The inner walls of the inner ends of the two arc-shaped elastic plates 424 are mounted on the lock shaft 421 through a spring return mechanism 423. A locking groove 4281 is provided at the end of the rotating shaft 428. A rod body 422 is provided on the inner wall of the annular lock body 43.

The lock core 42 is in a closed state before being locked. The upper and lower heights of the lock core 42 in the closed state are smaller than the height of the locking opening 100 formed by the first locking opening 417 and the second locking opening 431 .

[0033] The electric telescopic push rod 46, motor 47 and infrared sensor are respectively connected to and controlled by the central processing unit. The face recognition module, fingerprint recognition module and password input module are composed of software programs and implanted in the central processing unit. The face recognition module and fingerprint recognition module need to cooperate with the camera and fingerprint input device for operation and recognition.

[0034] When the lock is locked, the telescopic rod of the electric telescopic push rod 46 is extended to push the lock core 42 toward the lock plate 41, so that the lock core 42 enters the locking channel 414 after passing the first lock hole 417 and the second lock hole 431, and the end of the rotating shaft 428 of the lock core 42 is clamped into the clamping ring 429 through the opening, and the clamping protrusion 4291 is clamped into the clamping groove 4281, and the locking portion 426 is blocked in the locking hole 100 composed of the first lock hole 417 and the second lock hole 431.

When the extension length reaches the preset position, the arc channel 427 just corresponds to the position of the arc limit part of the annular lock body 43, and then the motor 47 works, so that the driving gear 44 drives the two to rotate in the same direction at the same time to drive the annular lock ring to rotate, so that the arc limit part of the annular lock body 43 is inserted into the arc In the channel 427, the front inner wall, rear inner wall, left inner wall and right inner wall of the arc channel 427 are used to limit and lock the arc limit part of the annular lock body 43, and the arc limit part is generally inserted from the upper end of the arc channel 427, so an infrared sensor is provided at the lower end of the arc channel 427. When the infrared sensor senses that the arc limit part has been reached, the motor is controlled to stop rotating. The motor adopts a brake servo motor, which can realize the brake after the motor is powered off without rotating under external force, so that the arc limit part is locked reliably. At the same time, the rod body 422 also rotates to drive the rotating shaft 428 to rotate, prompting the elliptical rotating plate 40 to rotate and causing the roller 401 to move along the arc inner wall of the arc elastic plate 424, so that the roller 401 moves from the lower end of the arc inner wall of the arc elastic plate 424 to its upper end, so as to synchronously lift the two arc elastic plates 424, so that the outer walls of the two arc elastic plates 424 are close to the inner wall of the lock groove.

[0035] When unlocking, the rotating shaft of the motor 47 rotates in the opposite direction, causing the driving gear 44 to drive the two to rotate in the same direction at the same time, so as to drive the annular lock ring to rotate, so that the arc-shaped limiting portion of the annular lock body 43 withdraws from the arc channel 427, and the elliptical rotating plate 40 rotates in the opposite direction, causing the roller 401 to move from the inner end of the arc-shaped elastic plate 424 to the outer end, thereby achieving the retraction of the two arc-shaped elastic plates 424. At this time, the two arc-shaped elastic plates 424 are in a closed state, and the upper and lower heights of the lock core 42 in the closed state are less than the upper and lower heights of the locking port 100 composed of the first lock port 417 and the second lock port 431. Then the telescopic rod of the electric telescopic push rod 46 retracts to separate the lock core 42 from the lock plate 41, thereby completing the unlocking, and the cabinet door 2 can be opened at this time.

[0037] In this embodiment, two limiting protrusions 413 are formed on the inner wall of the locking channel 414 and are relatively arranged. The two limiting protrusions 413 correspond to the positions of the second stop block 4242 at the inner end of the arc-shaped elastic plate 424 respectively. The two limiting protrusions 413 and the annular track plate 416 are combined with each other as an integral whole. The second stop block 4242 can cooperate with the limiting protrusion 413. When the two arc-shaped elastic plates 424 are unfolded, the second stop block 4242 contacts the limiting protrusion 413 to form a limit; a limiting protrusion 4241 is respectively provided at both ends of each arc-shaped elastic plate 424, and the two limiting protrusions 4241 and the arc-shaped elastic plate 424 are also combined with each other as an integral structure to improve the structural strength of the limiting structure.

[0038] In this embodiment, the spring return mechanism 423 includes a groove 4231 provided on the outer wall of the lock shaft 421, and a pressure spring 4232 and a L-shaped rod 4233 located in the groove 4231. A fixing ring is fixed at the notch of the groove 4231, and the pressure spring 4232 is sleeved on the longitudinal part of the L-shaped rod 4233. The upper end of the longitudinal part of the L-shaped rod 4233 passes through the inner hole of the fixing ring and is connected to the inner end of the arc spring plate. After the elliptical rotating plate 40 rotates in the opposite direction, the force exerted by the roller 401 on the arc elastic plate 424 disappears, and the L-shaped rod 4233 can be pushed downward under the action of the pressure spring 4232, prompting the arc elastic plate 424 to reset and making the two arc elastic plates 424 in a retracted state, so that the upper and lower heights of the lock core 42 are less than the upper and lower heights of the locking port 100.

[0039] In this embodiment, a cover plate 50 is fixed to a side surface of the lock plate 41 having the mounting groove to protect the gears.
