For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] Combine the following Figures 1 to 5 , describing a self-sealing door lock device according to an embodiment of the utility model.

[0036] A self-sealing door lock device comprises a housing 1, wherein a locking assembly 2, a transmission assembly 3 and an electric release assembly 4 are arranged in the housing 1; a lock hole is arranged at the top of the housing 1, and the lock head 5 is movably arranged in the lock hole through the housing 1;

[0037] The transmission assembly 3 is movably mounted on the housing 1, and the transmission assembly 3 includes a sealing plate 31, and the sealing plate 31 is used to seal the lock hole. The lock head 5 passes through the lock hole and abuts against the sealing plate 31, so that the sealing plate 31 moves downward, and the locking assembly 2 cooperates with the lock head 5 to achieve a locked state;

[0038] The electric release assembly 4 is installed at the bottom of the housing 1 and is connected to the bottom of the transmission assembly 3, so that the transmission assembly 3 moves upward, and the locking assembly 2 is separated from the lock head 5 to release the locking state.

[0039] In the present invention, a self-sealing door lock device is provided, wherein the lock head 5 penetrates into the housing 1 through the lock hole and presses downward against the sealing plate 31. The sealing plate 31 moves downward, so that the locking assembly 2 cooperates with the lock head 5 to ensure that the door lock device is in a locked state.

[0040] When releasing the locked state of the door lock, the electric release component 4 is started, and the electric release component 4 drives the sealing plate 31 to move upward, so that the locking component 2 is separated from the lock head 5, ensuring that the door lock device is in the unlocked state. Compared with the traditional door lock device, the electric release component 4 is used in this solution to realize the locking and unlocking of the door lock device. The electric release component 4 can be electrically connected to the controller to realize functions such as remote monitoring and intelligent control, improve the overall performance and intelligence level of the door lock system, and solve the problem that traditional door locks are difficult to achieve higher levels of security management and control.

[0041] The transmission assembly 3 includes a torsion spring 32 and a slider 33; one end of the torsion spring 32 is rotatably mounted on the housing 1, and the other end of the torsion spring 32 is rotatably connected to the slider 33. The moving direction of the slider 33 is the up and down direction. The top of the slider 33 is fixedly connected to the sealing plate 31. The electric release assembly 4 is connected to the slider 33, and the electric release assembly 4 is used to drive the slider 33 to move upward.

[0042] The electric release component 4 can drive the slider 33 to move upward in the shell 1. Since the slider 33 is fixedly connected to the sealing plate 31, the slider 33 can drive the sealing plate 31 to move upward together. At this time, the locking component 2 is separated from the lock head 5, and the lock head 5 leaves the shell 1 from the lock hole, so that the door lock device is unlocked.

[0043] In addition, the torsion spring 32 pushes the slider 33 upward, so that the sealing plate 31 seals the lock hole and restores the door lock device to the initial position or closed state. This automatic reset function can ensure that the lock hole remains closed without manual operation, effectively preventing foreign matter and dust from entering the door lock device.

[0044] The locking assembly 2 includes a locking body 21 and an elastic member 22, one end of the elastic member 22 is fixedly connected to the housing 1, and the other end of the elastic member 22 is fixedly connected to the locking body 21;

[0045] The locking body 21 is provided with a locking tongue 23, and the lock head 5 is provided with a hook 51, and the hook 51 cooperates with the locking tongue 23;

[0046] The sealing plate 31 movably contacts the locking body 21 to move the locking body 21 in the left-right direction.

[0047] It is worth noting that the elastic member 22 is a spring. When the sealing plate 31 moves upward, the sealing plate 31 abuts against the locking body 21 and pushes the locking body 21 to move to the left side of the housing 1, so that the locking tongue 23 on the locking body 21 and the hook 51 on the lock head 5 are disconnected. At this time, the lock head 5 can leave the housing 1 from the lock hole, and the door lock device is in an unlocked state.

[0048] When the lock head 5 penetrates into the housing 1 and presses the sealing plate 31 to move downward, the sealing plate 31 presses the locking body 21 to move left and right in the housing 1, so that the locking body 21 and the lock head 5 are close to each other, and the hook 51 cooperates with the lock tongue 23, and the door lock device is in a locked state.

[0049] The bottom of the locking body 21 is provided with a first inclined surface 24, and the first inclined surface 24 is inclined from bottom to top toward the right side of the housing 1;

[0050] A second inclined surface 25 is provided at the top of the locking tongue 23, and the second inclined surface 25 is inclined from bottom to top toward the left side of the shell 1. A third inclined surface 26 is provided at the bottom of the locking tongue 23, and the third inclined surface 26 is inclined from bottom to top toward the right side of the shell 1.

[0051] The sealing plate 31 moves upward under the action of external force, and the sealing plate 31 abuts against the first inclined surface 24, the third inclined surface 26 and the second inclined surface 25 in sequence, so that the locking body 21 moves to the left and right directions of the shell 1, and the lock tongue 23 is separated from the hook 51, and the door lock device is in an unlocked state.

[0052] When the sealing plate 31 moves downward under the action of external force, the sealing plate 31 first abuts against the second inclined surface 25, so that the locking body 21 moves to the left side of the housing 1 under the guidance of the second inclined surface 25, ensuring that the sealing plate 31 can continue to move downward. Then, the sealing plate 31 abuts against the third inclined surface 26 on the lock tongue 23, and the locking body 21 moves to the right side of the housing 1 under the guidance of the second inclined surface 25, so that the locking body 21 and the lock head 5 are close to each other, and the hook 51 cooperates with the lock tongue 23, so that the door lock device is in a locked state.

[0053] The electric release assembly 4 includes a power member 41, a worm 42, a reduction gear set 43 and a sliding member 44. The output end of the power member 41 is fixedly sleeved with the worm 42, and the worm 42 is meshed with the reduction gear set 43.

[0054] The sliding member 44 is located below the slider 33, and the sliding member 44 abuts against the slider 33. A rack 441 is provided on the side wall of the sliding member 44, and the rack 441 meshes with the reduction gear set 43. The length direction of the rack 441 and the sliding direction of the sliding member 44 are both in the up and down direction. The reduction gear set 43 is used to drive the sliding member 44 to move.

[0055] It is worth noting that the power member 41 is a small motor. When the power member 41 is started, it can drive the worm 42 to rotate, and the worm 42 drives the reduction gear set 43 to rotate, and the rotation of the reduction gear set 43 can drive the sliding member 44 to move up and down in the housing 1.

[0056] Among them, the reduction gear set 43 can convert the high-speed and low-torque rotational motion input by the worm 42 into a low-speed and high-torque rotational motion to adapt to the sliding speed of the sliding member 44, thereby improving the stability and reliability of the door lock device of this scheme.

[0057] The reduction gear set 43 includes a first reduction gear 431, a second reduction gear 432, a third reduction gear 433, a fourth reduction gear 434, a fifth reduction gear 435, a sixth reduction gear 436 and a seventh reduction gear 437;

[0058] The first reduction gear 431 is meshed with the worm 42, the first reduction gear 431 is coaxially arranged with the second reduction gear 432, the second reduction gear 432 is meshed with the third reduction gear 433, the third reduction gear 433 is coaxially arranged with the fourth reduction gear 434, the fourth reduction gear 434 is meshed with the fifth reduction gear 435, the fifth reduction gear 435 is coaxially arranged with the sixth reduction gear 436, the sixth reduction gear 436 is meshed with the seventh reduction gear 437, and the seventh reduction gear 437 is meshed with the rack 441.

[0059] It is worth noting that the second reduction gear 432, the fourth reduction gear 434 and the fifth reduction gear 435 are all small gears; the first reduction gear 431, the third reduction gear 433, the sixth reduction gear 436 and the sixth reduction gear 436 are all large gears. The worm 42 first meshes with the first reduction gear 431, the first reduction gear 431 is a large gear, and the second reduction gear 432 is a small gear, and the first reduction gear 431 and the second reduction gear 432 rotate coaxially, which effectively achieves a deceleration effect.

[0060] In addition, according to the mutual cooperation among the third reduction gear 433, the fourth reduction gear 434, the fifth reduction gear 435, the sixth reduction gear 436 and the seventh reduction gear 437, the deceleration effect can be further improved so that the sliding member 44 moves slowly on the housing 1.

[0061] The shell 1 is also provided with a push rod 6, the upper end of which is movably inserted into the shell 1, the upper end of which is slidably connected to the sliding member 44 and movably abuts against the slider 33, and the length direction of the push rod 6 is consistent with the moving direction of the sealing plate 31.

[0062] When the electric system is operating normally, the door lock can be opened quickly and conveniently by using the electric release method. When the power is off, the battery is exhausted, or the electric system fails, the user can manually push the push rod 6, which drives the slider 33 and the sealing plate 31 to move upward, thereby ensuring that the door lock is unlocked and the door is opened, thereby avoiding troubles or safety problems caused by failure to unlock, and increasing the reliability and safety of the door lock.

[0063] A limiting column is provided on one side of the locking body 21 close to the elastic member 22, and the other end of the elastic member 22 is sleeved on the limiting column; the housing 1 is provided with two limiting blocks 11 which are arranged opposite to each other, and the two limiting blocks 11 are respectively in contact with the top and bottom of the locking body 21.

[0064] The elastic member 22 is sleeved on the limiting column, which can effectively prevent the elastic member 22 from positional displacement during compression and stretching, and can also ensure that the elastic member 22 works stably and reliably within a specified range, thereby improving the overall performance and reliability of the door lock.

[0065] Moreover, the two limit blocks 11 on the shell 1 are not only arranged opposite to each other, but also respectively abut against the two sides of the locking body 21, further preventing the locking body 21 from being offset when the spring drives the locking body 21 to move, causing the locking body 21 to be unable to cooperate with the lock head 5.

[0066] A sealing strip is provided on the top of the sealing plate 31. The sealing strip in the sealing plate 31 can seal the lock hole to achieve waterproof and dustproof functions, further preventing foreign matter and dust from entering the door lock device.

[0067] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
