Description

Technical Field

[0001] The present invention relates to a lock structure, and more particularly to an intelligent lock structure. Background Art

[0002] As people's security awareness increases, smart locks are increasingly widely used. It is usually more complicated to open a door from the outside with a smart lock, requiring a mechanical key or electronic identification such as an access card, password, or fingerprint recognition to open the door from behind, while from the inside the door, you can usually just press down on the handle to quickly open the door. With this type of lock, criminals can open the door by destroying the structure of the cat's eye on the door or reaching into the door through the gap at the bottom of the door with a thin tool such as a wire to hook and pull the handle inside the door to rotate it, thus stealing without damaging it.

[0003] Therefore, in the prior art, there is a patent with patent number 2016109566979 that discloses a device for quickly switching the door handle on and off. By arranging a rotatable handle, a clutch assembly and a connecting assembly in combination, when someone wants to open the door by pulling the handle through the cat's eye hook to rotate it, the connecting assembly separates the handle from the clutch assembly to achieve the function of preventing the cat's eye from unlocking. The overall action of the connecting assembly is mainly achieved through the knob, that is, the switch is achieved by pressing the knob. However, since the knob is small in size and is arranged on the side of the handle facing away from the panel, people need to press the knob when they want to open and close the door. This will cause the problem of the knob irritating the fingers and causing discomfort to the fingers on the one hand, and on the other hand, it will be difficult to press the knob when opening the door. Summary of the invention

The core shaft 4 and the square rod rotating sleeve 3 are linked through the linkage component 5. The linkage component 5 includes a cat's eye button 51, a cat's eye connecting shaft 52 and a movable bolt 53. The cat's eye connecting shaft 52 is slidably arranged on the installation panel 2 and is arranged opposite to the end of the square rod rotating sleeve 3 so that it can be embedded in the square rod rotating sleeve 3 or removed from the square rod rotating sleeve 3. The cat's eye button 51 is arranged on the side of the handle 1 facing the installation panel 2 and is linked with the movable bolt 53. The cat's eye connecting shaft 52 is linked with the movable bolt 53 to be driven by the movable bolt 53 to be embedded in the square rod rotating sleeve 3 or to be removed from the square rod rotating sleeve 3. Compared with the method of pressing the knob in the prior art, the structure of this embodiment sets the starting cat's eye button 51 on the side of the handle 1 facing the mounting panel. In this way, when people hold the handle 1 and prepare to open the door, their fingers will press the cat's eye button 51. Therefore, compared with the method of pressing the knob with the thumb in the prior art, on the one hand, the thumb will not be annoyed, and on the other hand, there will be no problem of difficulty in pressing the knob. In addition, the combination of the movable bolt 53 and the cat's eye connecting shaft 52 can realize the connection or separation of the handle 1 and the square rod rotating sleeve 3.

[0016] As an improved specific implementation, an anti-cat's eye connecting rod 13 is provided in the handle 1, and the midpoint of the anti-cat's eye connecting rod 13 is rotatably fixed to the handle 1 through a connecting pin. One end of the anti-cat's eye connecting rod 13 is hinged to one end of a movable bolt 53 facing away from the cat's eye connecting shaft 52, and the other end is arranged in the handle 1 at a position close to the cat's eye button 51 so as to be rotated by the cat's eye button 51. A cat's eye spring 54 is coaxially sleeved on the movable bolt 53, and the cat's eye spring 54 is in a compressed state. The anti-cat's eye connecting rod 13 is used to link the movable bolt 53 and the cat's eye button 51, so as to better fit the situation of insufficient space in the handle 1.

[0017] As an improved specific implementation, the handle 1 includes a cat's eye handle 11 and a cat's eye handle cover 12, one end of the cat's eye handle 11 is provided with a connecting cylinder, the end of the connecting cylinder facing away from the cat's eye handle 11 is rotatably mounted on the mounting panel 2, the movable bolt 53 is slidably fixed to the connecting cylinder by a hexagon socket screw, a groove is provided on the side of the cat's eye handle 11 facing away from the mounting panel 2, the anti-cat's eye connecting rod 13 is mounted on the groove wall of the groove, the cat's eye button 51 is mounted on the groove bottom of the groove and extends to the outside, and the cat's eye handle cover 12 covers the notch of the groove, so that a space for accommodating the anti-cat's eye connecting rod 13 can be simply and effectively realized.

[0018] As an improved specific implementation method, a handle mounting hole is opened on the mounting panel 2, and the connecting cylinder is installed in the handle mounting hole through a bearing. A bearing sleeve 21 is provided on the bearing, and the bearing sleeve 21 is fixedly connected to the hole wall of the handle mounting hole. In this way, the connecting cylinder can be rotatably mounted on the mounting panel 2 by using the bearing.

[0019] As a specific embodiment of the improvement, the core shaft 4 includes a core disk 41 and a stopper 42 evenly distributed on the circumference of the core disk 41. The mounting panel 2 is provided with a reversing slide pin 22 that can slide up and down relative to the position below the core shaft 4. The reversing slide pin 22 slides upward and abuts against the stopper 42, thereby positioning the core shaft 4. The stopper 42 includes a rotating stopper 421 and two reversing stops 422. The rotating stopper 421 and the two reversing stops 422 are arranged on the circumference of the core disk 41 in the form of a reversing stopper 422-rotating stopper 421-reversing stopper. 422 are distributed, and the angle between them is 90 degrees, and the two reversing blocks 422 are connected by a semicircular arc to form a semicircular structure of the core disk 41, and the two reversing blocks 422 and the rotating block 421 are hollowed out. Through the combination of the reversing slide pin 22 and the rotating block 421 on the core shaft 4 and the reversing block 422, the effect of the changeable direction of the handle 1 can be simply and effectively achieved, and after the direction of the handle 1 is changed, the handle 1 itself still has a certain degree of rotation, which greatly facilitates people's use of the smart door lock.

[0020] As an improved specific implementation method, four threaded columns are provided at the position of the mounting panel 2 relative to the reversing sliding pin 22, two threaded columns form a group, and a track for the reversing sliding pin 22 to slide is formed between the two groups of threaded columns. The ends of the four threaded columns facing away from the mounting panel 2 are fixedly connected to the sliding pin pressure plate 23 by screws, and a waist-shaped hole is opened in the middle of the sliding pin pressure plate 23. A sliding pin compression spring 24 is sleeved on the reversing sliding pin 22, and an adjusting screw is threadedly connected on the side facing the sliding pin pressure plate 23. The body of the adjusting screw passes through the waist-shaped hole and is threadedly connected to the reversing sliding pin 22, and the head diameter of the adjusting screw is larger than the aperture of the waist-shaped hole. Through the arrangement of the above structure, the reversing sliding pin 22 can be simply and effectively positioned, and the reversing sliding pin 22 can also be driven to slide by a screwdriver embedded in the adjusting screw, thereby realizing the conversion of the direction of the handle 1.

[0021] To sum up, the smart lock structure of this embodiment can avoid the pressing knob method used in the prior art by configuring the linkage component 5 to be a cat's eye button 51, a cat's eye connecting shaft 52 and a movable bolt 53, and configuring the cat's eye button 51 on the side of the handle 1 facing the mounting panel 2. On the one hand, there is no need to press with the thumb, which increases the comfort of pressing. On the other hand, when a person holds the handle 1, the fingers will automatically press on the cat's eye button 51, avoiding the problem of difficulty in pressing.
