Description

Technical Field

[0001] The utility model specifically relates to the technical field of intelligent locks, in particular to an upward-lifting and anti-locking intelligent door handle. Background Art

[0002] Smart locks (foreign name Intelligent Lock) refer to locks that are different from traditional mechanical locks and are more intelligent in terms of user identification, security, and management. Smart locks are the executive components of door locks in access control systems. Electronic locks cannot be called smart locks. The sign of smart locks is whether they can be remotely controlled by mobile phones and linked with smart homes.

[0003] Existing smart locks all have the function of lifting up to lock, but because the residents are divided into east and west households, the opening directions of the entrance doors are inconsistent. For example, when the door is opened on the left, it can be locked by lifting up, but when the door is opened on the right, the direction of the door handle needs to be changed. After the direction is changed, the door handle cannot realize the function of lifting up to lock, which is very inconvenient to use. It is necessary to determine whether it is left or right before purchasing. If you buy the wrong one, you need to replace it, which brings great inconvenience to users. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] See also Figure 1-11 In an embodiment of the utility model, a lift-up anti-lock smart door handle comprises an outer door handle 1 and an inner door handle 3; the outer door handle 1 and the inner door handle 3 are respectively mounted on the two ends of a square shaft 2; the outer door handle 1 comprises a driving block 16 bolted to the top of a fixed plug block 11, the middle position of the driving block 16 has a circular hole with a diameter larger than the square shaft 2, and is sleeved on the square shaft 2, a shifting block 17 is arranged above the driving block 16, a torsion spring 24 is arranged above the shifting block 17, and the torsion spring 24 is embedded below the top block 18; a fixing plate 19 is arranged above the top block 18;

[0031] A circular hole is provided in the middle of the fixing plate 19, and holes are provided on both sides of the circular hole for fixing the bolts to the door body, and one of the holes is provided with a hole A and a hole B; a groove a and a groove b corresponding to the hole A and the hole B are provided at one end of the driving block 16; a toggle shaft is provided in the hole A or the hole B.

[0032] By adopting the above technical solution, if the door is left-opening, the toggle shaft or bolt is passed through hole A, so that the end of the toggle shaft is clamped in groove a. When the left-opening door is lifted and locked, it is rotated clockwise. During the rotation process, the toggle shaft presses down the protruding block at one end of the toggle block 17, and the middle of the pressing block 17 is provided with a square hole, which cooperates with the square shaft 2, so that the square shaft 2 can be driven to rotate, so that the door lock can be lifted and locked;

[0033] If the door opens to the right, the installation direction of the outer door handle 1 and the inner door handle 3 needs to be rotated 180 degrees. At this time, the installation method of the toggle shaft needs to be adjusted as follows: pass through hole B so that the end of the toggle shaft is clamped in groove b. When the right-opening door is lifted up and locked, it is rotated counterclockwise. During the rotation, the toggle shaft presses down the raised block at one end of the toggle block 17, so that the door lock can be lifted up and locked.

[0034] Through the arrangement of the above scheme, the left-opening door and the right-opening door can be switched and the condition of lifting and locking can be met, which is very convenient to use.

[0035] In this embodiment, circular holes are provided on both sides of the fixed block 11 for facilitating the installation of the lock core 13 and the motor 20; the lock core 13 is fixed in the fixed block 11, the lower end of the lock core 13 cooperates with the key socket on the handle housing 10, and the upper end is connected with a first protrusion 14; the first protrusion 14 is fitted with a first sliding shaft 15; the first sliding shaft 15 is slidably connected in the hole on one side of the driving block 16.

[0036] By adopting the above technical solution, when using the key to unlock the door, the key is first inserted into the keyhole on the handle housing 10, and then the key enters the lock core 13. Then the key is twisted, and the lock core 13 drives the first protrusion 14 to rotate. The rotating first protrusion 14 inserts the first sliding shaft 15 into the hole on the shift block 17. At this time, the handle is turned again, and the door lock can be twisted through the square shaft 2, thereby realizing the opening of the door lock.

[0037] In this embodiment, a second protrusion 21 is mounted on the output shaft of the motor 20 , and a second sliding shaft 22 is fitted and connected to the second protrusion 21 ; the second sliding shaft 22 is slidably connected to the hole on the other side of the driving block 16 .

[0038] More specifically, the motor 20 is electrically connected to the circuit board 12 , and the circuit board 12 is fixed to one side of the driving block 16 by screws; a fingerprint module 25 is also embedded on the outer end surface of the handle housing 10 ; the fingerprint module 25 is also electrically connected to the circuit board 12 .

[0039] By adopting the above technical solution, when using fingerprint recognition, the fingerprint is recognized by the fingerprint module 25. When the match is formed, the circuit board 12 sends a command to the motor 20, and the motor 20 drives the second protrusion 21 to rotate and pushes the second sliding shaft 22 into the hole on the dial block 17. At this time, by turning the handle, the door lock can be twisted through the square shaft 2, thereby realizing the opening of the door lock.

[0040] In this embodiment, a battery box is provided in the inner door handle 3 , and the wires in the battery box are electrically connected to the circuit board 12 and the motor 20 .

[0041] The working principle of the utility model is: if the door is left-opening, the toggle shaft or bolt is selected to pass through the A hole so that the end of the toggle shaft is clamped in the groove a. When the left-opening door is lifted and locked, it is rotated clockwise. During the rotation process, the toggle shaft presses down the protruding block at one end of the toggle block 17, and the middle of the pressing block 17 is provided with a square hole, which cooperates with the square shaft 2, so that the square shaft 2 can be driven to rotate, so that the door lock can be lifted and locked;

[0042] If the door opens to the right, the installation direction of the outer door handle 1 and the inner door handle 3 needs to be rotated 180 degrees. At this time, the installation method of the toggle shaft needs to be adjusted as follows: pass through hole B so that the end of the toggle shaft is clamped in groove b. When the right-opening door is lifted up and locked, it is rotated counterclockwise. During the rotation, the toggle shaft presses down the raised block at one end of the toggle block 17, so that the door lock can be lifted up and locked.

[0043] When using the key to unlock the door, first insert the key into the keyhole on the handle housing 10, then the key enters the lock core 13, and then the key is twisted. The lock core 13 drives the first protrusion 14 to rotate. The rotating first protrusion 14 inserts the first sliding shaft 15 into the hole on the shift block 17. At this time, turn the handle again to twist the door lock through the square shaft 2, thereby realizing the opening of the door lock.

[0044] When using fingerprint recognition, the fingerprint is recognized by the fingerprint module 25. After the match is formed, the circuit board 12 sends a command to the motor 20. The motor 20 drives the second protrusion 21 to rotate and pushes the second sliding shaft 22 into the hole on the dial block 17. At this time, by turning the handle, the door lock can be twisted through the square shaft 2, thereby realizing the opening of the door lock.
