[0002] In existing door systems, the handle of a traditional door lock is usually located on the back of the lock. Since doors have two different opening methods, left-opening and right-opening, the handle is usually disassembled during installation. The reversing structure is adjusted to adapt to the specific opening direction of the door, and then it is fixed after installation.
[0003] With the development of technology and the improvement of people's aesthetic needs, modern fingerprint locks have designed door handles as small rectangular structures that exceed the range of traditional door lock bodies in order to achieve a more beautiful design effect. However, while this innovative design brings aesthetic advantages, it also raises new problems. Because the distance between the door handle and the door frame is relatively smaller, users face a higher risk of their fingers being pinched during the closing process, which undoubtedly brings obvious safety hazards to the user experience.

[0026] The present invention will be further described in detail below with reference to embodiments:
[0027] like Figure 1-7 As shown, this utility model provides a fingerprint lock handle reversing structure, including a handle connecting block 2 for connecting to a lock plate 1. The end of the handle connecting block 2 away from the lock plate 1 is connected to a handle 3. The surface of the handle 3 has a back groove 4 and a front groove 5 that communicate with each other. The end of the handle connecting block 2 located in the back groove 4 of the handle 3 is provided with multiple locking holes 6. The surface of the handle 3 is provided with an adjustment groove 7 that communicates with the back groove 4. The inner wall of the adjustment groove 7 is provided with a spring 8. One end of the spring 8 is provided with a reversing latching piece 9 located in the adjustment groove 7. One end of the reversing latching piece 9 is adapted to the locking hole 6 on the handle connecting block 2. A rotation limiting piece 10 for limiting the up and down movement of the reversing latching piece 9 is fixedly installed in the adjustment groove 7. When one end of the reversing latching piece 9 is disengaged from the locking hole 6, it is used for reversing adjustment of the handle 3.
[0028] like Figure 2 As shown, further, one end of the handle connecting block 2 is provided with an arc-shaped area 11, and the inner wall of the arc-shaped area 11 is connected with a plurality of irregular blocks 12, and a locking port 6 is formed between every two irregular blocks 12. There are three locking ports 6, two of which are correspondingly arranged, and the included angle between the center lines of every two adjacent locking ports 6 is a positive angle.
[0029] The design of three locking lugs 6 allows the reversing latch 9 to disengage from the locking lugs 6, enabling the handle 3 to make a 90-degree adjustment in either the forward or reverse direction (e.g., ...). Figure 6 As shown), the repositioning of handle 3 can increase the distance between the door lock and the hand, avoiding the problem of pinching the hand. Furthermore, after the handle 3 is repositioned from left to right, the force of spring 8 enables the handle 3 to be positioned, providing a certain degree of stability.
[0030] It is worth noting that although this article aims to provide left, top, center, and right repositioning of the handle 3, it is not limited to this kind of right angle repositioning. Acute angles can also be set during production according to actual usage to meet different scenario requirements.
[0031] Furthermore, such as Figure 2 , Figure 3 and Figure 4 As shown, the adjustment groove 7 includes an active area 71 and a positioning area 72. The reversing fastener 9 is movably disposed in the active area 71, and the rotation limiter 10 is fixedly installed in the positioning area 72. Two symmetrically arranged anti-collision areas 13 are opened at one end of the active area 71 near the back groove 4. The reversing fastener 9 includes a locking piece 91, an arc-shaped block 92 connected to both sides of the locking piece 91, and a lever 93 connected to the surface of the locking piece 91. The two arc-shaped blocks 92 are respectively adapted to the corresponding anti-collision areas 13, and the inner ring wall of the arc-shaped block 92 is attached to the outer ring wall of the irregular block 12.
[0032] Specifically, the design of two anti-collision zones 13 allows the reversing latch 9 to move, thereby causing one end of the reversing latch 9 to disengage from the inside of the locking port 6, thus realizing the repositioning adjustment of the handle 3. This ensures that the repositioned handle 3 not only ensures safety but also conforms to ergonomics and has a certain degree of practicality.
[0033] As a further step, the inner wall of the active area 71 is provided with a first groove 15, and the surface of the rotating limiting piece 10 is provided with a second groove 16, and the second groove 16 is correspondingly provided with the first groove 15. The cooperation of the first groove 15 and the second groove 16 allows the outer ring of the spring 8 to be located in the corresponding groove, thereby avoiding the problem that the spring 8 cannot be used due to the narrow space.
[0034] The top of the locking piece 91 is provided with a limiting protrusion, and one end of the spring 8 is located on both sides of the limiting protrusion. The design of the limiting protrusion helps to stabilize the spring 8 and prevent the spring 8 from shifting, thereby ensuring the stability of the reversing latch piece 9.
[0035] Combination Figure 4 and Figure 5As shown, a strip-shaped opening 14 is provided through the surface of the rotating limiting piece 10, and the push post 93 is located inside the strip-shaped opening 14. The arc-shaped opening at the bottom of the rotating limiting piece 10 is adapted to the outer ring wall of the irregular block 12.
[0036] One end of the lever 93 extends through the strip opening 14 to one side of the rotating limiting plate 10, so that the protruding lever 93 can be manually moved to facilitate the reversing latch plate 9, thereby facilitating the repositioning adjustment of the handle 3; and the arc-shaped opening at the bottom of the rotating limiting plate 10 always fits against the outer ring wall of the irregular block 12 when the handle 3 is repositioned, thereby ensuring the stability of the handle 3 during repositioning and avoiding misalignment.
[0037] Combination Figure 5 As shown, a fixing piece 18 is provided in the front groove 5. A through hole is provided on the surface of the fixing piece 18, and a mounting hole 19 is provided at one end of the handle connecting block 2. The mounting hole 19 corresponds to the through hole. The design of the through hole and the mounting hole 19 facilitates the fixing of the handle 3 by the fixing piece 18. A decorative groove is provided on the side of the handle 3 away from the handle connecting block 2. A handle decorative piece 17 is provided in the decorative groove. The opening of the decorative groove facilitates the positioning of the handle decorative piece 17 to prevent shaking. It also ensures the aesthetics of the surface of the handle 3. The handle decorative piece 17 is located on one side of the fixing piece 18.
[0038] The working principle of this fingerprint lock handle reversing structure will be explained in detail below.
[0039] like Figure 1-7 As shown, when the user needs to change the direction of the handle 3, the shift pin 93 is manually moved, causing the shift pin 93 to move the locking piece 91 within the moving area 71, thereby causing one end of the locking piece 91 to disengage from the inside of the locking port 6. Based on this, the user can simultaneously rotate the handle 3 to the left or right. After the rotation direction is determined, the rotation limit piece 10 can be used to stop the rotation at the bottom plane of the arc area 11. Then, the user can release the shift pin 93, causing the locking piece 91 to reset with the help of the spring 8, so that the locking piece 91 can enter the changed locking port 6, thereby completing the change of the handle 3.
[0040] It should be noted that when the handle 3 is being adjusted for reversing, one method is for the user to directly rotate the handle 3 after the reversing latch 9 disengages from the locking lug 6. Another method is to loosen or remove the fixing plate 18 and then rotate the handle 3 after the reversing latch 9 disengages from the locking lug 6. The specific method can be used according to the actual situation.
[0041] It should be noted that, in the description of this disclosure, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joint" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.
[0042] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
