Detailed Implementation

[0022] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0023] like Figs. 1-3 As shown: A high-sealing lock structure includes a mounting plate 1, a faceplate 2, a lock cylinder mechanism 3, and a sealing mechanism 4. The lock cylinder mechanism 3 and the sealing mechanism 4 are disposed on the mounting plate 1, and the faceplate 2 covers the mounting plate 1.

[0024] The lock cylinder mechanism 3 includes a drive mechanism 31 and a latch 32. The latch 32 is connected to the drive mechanism 31. The side of the mask 2 is located in the lock groove 21, and the latch 32 is slidably located in the lock groove 21. The sealing mechanism 4 includes a drive assembly 41 and a sealing plate 42. The sealing plate 42 is slidably located in the side wall of the mask 2 and is connected to the drive assembly 41. The sealing plate 42 can close the lock groove 21.

[0025] When the latch 32 extends, the sealing plate 42 retracts into the side wall of the faceplate 2. When the latch 32 retracts, the sealing plate 42 extends to completely seal the lock groove 21, preventing external moisture and dust from entering.

[0026] The lock groove 21 is equipped with a sealing ring, and the side of the faceplate 2 has a cavity, in which the sealing plate 42 is located. The sealing ring fills the gap between the bolt 32 and the lock groove 21, preventing external dust and moisture from entering the interior of the lock when the bolt 32 moves back and forth.

[0027] Specifically, the driving mechanism 31 comprises a DC motor 311, a worm 312, a turbine 313 and a toothed plate 314. The DC motor 311 is arranged on the mounting plate 1. The worm 312 is connected with the output shaft of the DC motor 311. The turbine 313 is rotatably arranged on the mounting plate 1 and connected with the worm 312. The toothed plate 314 is connected with the turbine 313. The locking tongue 32 is connected with the toothed plate 314. The turbine 313 is coaxially provided with a gear. The toothed plate 314 is engaged with the gear. The upper side of the face shield 2 is provided with a set of mounting blocks. The toothed plate 314 is slidingly arranged on the mounting blocks. The DC motor 311 drives the worm 312 to rotate. The turbine 313 connected with the worm 312 rotates. The gear on the turbine 313 can drive the toothed plate 314 to reciprocate, so as to realize the extension or retraction of the locking tongue 32.

[0028] As shown in Fig. 2 , the mounting blocks are provided with contact sensors 22. The toothed plate 314 is provided with a sensing column 315. The sensing column 315 is limited between two mounting blocks. When the sensing column 315 contacts with the left contact sensor 22, it indicates that the locking tongue 32 has been retracted into the lock. When the sensing column 315 contacts with the right contact sensor 22, it indicates that the locking tongue 32 has been completely extended to the locking position.

[0029] The driving assembly 41 comprises a driving motor 411, a gear set 412 and a rack 413. The driving motor 411 and the gear set 412 are arranged on the mounting plate 1. The rack 413 is connected with the lower part of the sealing plate 42. The driving motor 411 is connected with the rack 413 through the gear set 412.

[0030] In addition, one side of the mounting plate 1 is further provided with a control box 11. The control box 11 is provided with a battery and a controller. The battery is connected with the DC motor 311 and the driving motor 411. The controller is electrically connected with the DC motor 311, the driving motor 411 and the contact sensor 22. The battery provides power source for the entire lock. The controller controls the state of the driving motor 411 and the DC motor 311. When the locking tongue 32 is retracted in place, the controller 22 receives the signal of the contact sensor 22. Then the controller drives the driving motor 411 to act, so as to drive the sealing plate 42 to rise and seal the lock groove 21. When the locking tongue 32 needs to be extended, the sealing plate 42 will be retracted first.

[0031] As shown in Fig. 3 , the control box 11 is further provided with a USB interface 12. The USB interface can be used as a charging interface of the battery. When the battery is insufficient, the USB interface can be used as an interface of an external power supply.

[0032] The above merely is the preferred embodiment of the present application, it should be pointed out that, for ordinary skilled person in the art, without departing from the principles of the present application, can make a number of improvements, these improvements also should be considered as the protection scope of the present application.
