AI Technical Summary
When the mechanical lock core is violently drilled through, it is easily opened by objects such as screwdrivers or small iron rods. The anti-theft performance is insufficient and there is a great potential risk.
A rotating handle with anti-theft function is designed, and an anti-theft mechanism is used to electrically connect it to the battery, including a clutch, drive assembly, slider and mechanical lock core. The mechanical lock core is driven by a motor drive slider to push the lock, thereby enabling the opening and closing of the lock and preventing illegal damage.
When the mechanical lock core is violently drilled through, it is still possible to prevent the door lock from being opened with objects such as screwdrivers or small iron rods, which significantly improves the anti-theft performance of the electric hand lock and reduces potential risks.

[0025] As Figure 1-2 It is a schematic structural diagram of a rotary handle with anti-theft function according to a preferred embodiment of the present utility model. In this embodiment, a rotary handle with anti-theft function includes a rear handle 1 and a front handle 2. The rear handle 1 and the front handle 2 are connected by a square rotating column 3. A battery installation cavity 11 is provided in the rear handle 1, and a plurality of groups of batteries 12 are arranged in the battery installation cavity 11. An anti-theft installation cavity 21 is provided in the front handle 2, and an anti-theft mechanism 8 is arranged in the anti-theft installation cavity 21. The anti-theft mechanism 8 is electrically connected to the battery 12. A lock port 26 is provided on one side of the outer wall of the front handle 2, and the lock port 26 is communicated with the inside of the anti-theft installation cavity 21.
[0026] In this embodiment, the anti-theft mechanism 8 includes a clutch 7, a driving assembly 4, a slider B5, and a mechanical lock core 6. A clutch 7 is movably connected to one end of the driving assembly 4 in the anti-theft installation cavity 21. A mechanical lock core 6 is movably connected to the other end of the driving assembly 4 in the anti-theft installation cavity 21. A slider B5 is slidably connected behind the driving assembly 4 in the anti-theft installation cavity 21, and one end of the slider B5 is in contact with the driving assembly 4, and the other end of the slider B5 is in contact with the mechanical lock core 6.
[0027] In this embodiment, the driving component 4 includes a motor 41, a slider A 42, a push rod 43, a push rod spring 45, and a motor spring 44. The output end of the motor 41 is fixedly connected to the slider A 42. One side of the slider A 42 away from the motor 41 is fixedly connected to the push rod 43. A connection cavity 422 is formed in the slider A 42. The motor spring 44 is assembled in the connection cavity 422, and the motor spring 44 is sleeved on the surface of the output end of the motor 41. The push rod spring 45 is sleeved on the surface of the push rod 43.
[0028] In this embodiment, in the anti-theft installation cavity 21, a first installation position 22, a second installation position 23, a third installation position 24, and a fourth installation position 25 are sequentially formed from left to right. A clutch 7 is rotatably connected in the first installation position 22, the push rod spring 45 is assembled in the second installation position 23, the slider A 42 is slidably connected in the third installation position 24, and the motor 41 is fixedly installed in the fourth installation position 25. With this structural arrangement, installation spaces are provided for the clutch 7, the push rod spring 45, the slider A 42, and the motor 41, preventing the phenomenon of position disorder during use.
[0029] In this embodiment, a fixed block 421 is fixedly connected to the rear surface of the slider A 42, and a convex hull 61 is fixedly connected to one side of the mechanical lock core 6 close to the motor 41.
[0030] In this embodiment, both ends of the slider B 5 are in contact with the fixed block 421 and the convex hull 61 respectively.
[0031] In this embodiment, a connection groove 71 is formed on the surface of the clutch 7, and the push rod 43 is movably connected in the connection groove 71.
[0032] Working principle
[0033] Specifically, when the motor 41 receives a correct instruction (correct fingerprint, password, etc.), the output end starts to rotate. As a result, the motor spring 44 and the motor 41 generate relative displacement to push the slider A 42 towards the push rod 43, pushing the push rod 43, compressing the push rod spring 45, and entering the connection groove 71 of the clutch 7.
[0034] In this state, if an external force causes the front handle 2 to rotate, then the clutch 7 will rotate together with the front handle 2, thereby driving the square rotating column 3 and the lock body to achieve the door opening state.
[0035] If the motor does not receive the correct instructions (correct fingerprint, password, etc.) or does not receive any instructions and is in a non-powered state, then the ejector rod 43 will be ejected from the connection slot 71 of the clutch 7 by the ejector spring 45. In this state, if an external force causes the front handle 2 to rotate, the clutch 7 will not rotate with the front handle 2, nor will it drive the square rotating column 3 and the lock body to achieve the door opening state. Thus, it plays a role in anti-theft.
[0036] When it is necessary to use the mechanical lock core 6 to unlock (when the door lock has no power and there is no backup power supply), insert the correct key from the keyhole 26. The key drives the mechanical lock core 6 to rotate together. At this time, the convex bump 61 at the upper end of the mechanical lock core 6 pushes the slider B5 to move, driving the slider A42 to move and push the ejector rod 43, so that it compresses the ejector rod spring 45 and enters the connection slot 71 of the clutch 7.
[0037] In this state, if an external force causes the front handle 2 to rotate, the clutch 7 will rotate with the front handle 2, thereby driving the square rotating column 3 and the lock body to achieve the door opening state.
[0038] The above content further elaborates on the present invention in combination with specific embodiments. It cannot be determined that the specific implementation of the present invention is only limited to these descriptions. For those of ordinary skill in the technical field to which the present invention pertains, without departing from the concept of the present invention, several simple deductions or substitutions can still be made, which should all be regarded as falling within the protection scope determined by the claims submitted for the present invention.
