Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0029] like Figures 1-6 As shown, a double-leaf door handle lock assembly includes a first lock body 100 and a second lock body 200, and a connecting rod 300 for connecting the first lock body 100 and the second lock body 200. Both the first lock body 100 and the second lock body 200 are provided with lock sleeves for engaging door handles. At least one lock sleeve is composed of a fixed member 102 and a movable member 103, and the movable member 103 can rotate and open relative to the fixed member 102. The first lock body 100 is provided with a locking mechanism 400 for locking the movable member 103.

[0030] like Figure 1 and Figure 2 As shown, in this embodiment, the lock sleeve includes a first lock sleeve 101 and a second lock sleeve 201 respectively disposed on the first lock body 100 and the second lock body 200. The first lock sleeve 101 and the second lock sleeve 201 are columnar hollow structures. The columnar hollow structures can match the door handles and are compatible with most door handles on the market, thus improving the universality and practicality of the lock.

[0031] like Figure 1 and Figure 2 As shown, in this embodiment, the first lock sleeve 101 is disposed on the first lock body 100 and is composed of a fixed member 102 and a movable member 103; wherein, the fixed member 102 is fixedly connected to the first lock body 100, and the movable member 103 is hinged to the other end of the fixed member 102. The movable member 103 and the fixed member 102 are hinged together by a hinge. The movable member 103 can rotate relative to the fixed member 102 within a certain angle through the hinge to realize the opening and closing of the first lock sleeve 101.

[0032] In other embodiments (not shown in the figures), the fixed member 102 and the movable member 103 can also be connected by other means such as bearing connection and gear mechanism connection.

[0033] like Figure 1, Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, the locking mechanism 400 includes a rotary combination lock 401 installed within the first lock body 100, and a bolt 406 slidably installed within the first lock body 100. The user inputs a predetermined password by rotating the dial of the rotary combination lock 401, and the lock unlocks by decoding. This combination lock design offers high security; password combinations prevent unauthorized personnel from opening the lock. Furthermore, the rotary combination lock 401 has a simple and reliable mechanical structure, capable of withstanding prolonged use without easily being damaged. The movable component 103 has a latch groove 104 at one end facing the first lock body 100. One end of the latch 406 extends through the first lock body 100 and can be inserted into the latch groove 104. A return spring 405 is installed at the other end of the latch 406. The latch 406 is connected to a transmission block 403 located inside the first lock body 100. A locking rod 402 is provided on the axis of the rotary combination lock 401 and is connected to the transmission block 403. The locking rod 402 is locked by the rotary combination lock 401 to achieve the locking function. The transmission block 403 is also fixedly connected to a sliding button 404. The sliding button 404 extends through the first lock body 100 and is slidably connected to the first lock body 100. The design of the sliding button 404 allows the user to directly operate the sliding button 404 to achieve the sliding and locking functions of the latch 406. The exposed part of the sliding button 404 is easy for the user to access, and through sliding operation, the user can easily and intuitively perform unlocking and locking operations. The sliding connection of the slider 404 ensures smooth operation and avoids jamming or difficulty in operation.

[0034] In the locked state, the rotary combination lock 401 locks the locking bar 402, and the return spring 405 pushes the bolt 406 to be tightly inserted into the bolt groove 104, ensuring that the moving part 103 is tightly engaged with the first lock body 100. The supporting force of the return spring 405 prevents the bolt 406 from accidentally sliding out under improper external force or in the event of incorrect unlocking, thereby improving the security and reliability of the lock. When the rotary combination lock 401 is unlocked, the rotary combination lock 401 releases the restriction on the locking bar 402, and slides the sliding button 404 toward the rotary combination lock 401. The sliding button 404 drives the locking bar 402 and the bolt 406 to slide through the transmission block 403. The lock slides out from the bolt groove 104 and compresses the return spring 405. At this time, the movable part 103 can rotate relative to the fixed part 102, opening the first lock sleeve 101, so that the door lock can be removed from the door handle. When the sliding button 404 loses external force, the return spring 405 pushes the bolt 406 to return to its original position. At the same time, the bolt 406 drives the locking bar 402 and the sliding button 404 to return to their original position through the transmission block 403.

[0035] In other embodiments (not shown in the figure), the reset spring 405 can also be replaced by other elastic components, such as elastic telescopic rods, spring sheets, rubber pads, and magnetic rebound to achieve the reset function. The appropriate elastic component can be selected to achieve the reset function according to the specific application scenario and requirements.

[0036] like Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, the side of the latch 406 near the latch groove 104 and the outer side of the latch groove 104 are both designed with guide surfaces. The guide surfaces reduce hard friction between components by optimizing the contact angle, so that the moving part 103 can smoothly push the latch 406 to slide and insert into the latch groove 104, effectively reducing frictional resistance and jamming, and improving the reliability and durability of the components.

[0037] In other embodiments (not shown in the figures), the rotary combination lock 401 can also be replaced with a fingerprint lock, a traditional key lock cylinder, or a hybrid unlocking method (fingerprint + key lock cylinder), providing multiple unlocking options to meet the needs of different users. Fingerprint locks offer a more secure and convenient unlocking method through high-tech means, while traditional key lock cylinders provide a more familiar and simple solution. These alternatives not only enhance the adaptability of the lock but also improve the user experience, better meeting the needs of diverse locations such as homes and offices. In future implementations, users can choose different unlocking methods according to their actual needs, making the lock more diversified in terms of security, convenience, and applicability.

[0038] like Figure 1 and Figure 5 As shown, in this embodiment, an adjustment mechanism is provided between the second lock body 200 and the connecting rod 300. The design of the adjustment mechanism allows the distance between the first lock body 100 and the second lock body 200 to be flexibly adjusted according to actual usage requirements, thereby meeting the size requirements of various door panels and further improving the applicability and ease of installation of the lock.

[0039] The adjustment mechanism includes an external thread on the connecting rod 300 and a threaded hole in the second lock body 200. Specifically, the unthreaded end of the connecting rod 300 is fixedly connected to the first lock body 100, while the threaded end is inserted into the threaded hole in the second lock body 200. The spacing is adjusted via this threaded connection. The user adjusts the spacing between the first and second lock bodies 100 by rotating the second lock body 200. The threaded connection between the external thread and the threaded hole ensures stability and accuracy during adjustment, preventing loosening or instability. The connecting rod 300 is made of high-strength, corrosion-resistant alloy materials, such as stainless steel or aluminum alloy, to ensure sufficient mechanical strength and durability during long-term use. The use of high-strength materials effectively enhances the load-bearing capacity of the connecting rod 300, allowing it to maintain stable performance even under significant external forces, preventing lock failure due to mechanical fatigue or deformation.

[0040] Furthermore, the use of threaded connections allows for more precise adjustments, preventing instability or malfunctions caused by inaccurate spacing. After adjustment, the tightness between the connecting rod 300 and the threaded hole ensures the lock body's stability during use, further enhancing its security and stability. The installation and adjustment of the lock become more flexible, convenient, and adaptable.

[0041] In another embodiment (not shown in the figure), the first lock body 100 and the second lock body 200 are equivalent and interchangeable. For example, the locking mechanism 400 and the first lock sleeve 101 are disposed in the second lock body 200, and the adjustment structure is disposed in the first lock body 100.

[0042] In summary, as can be seen from the above description, this utility model achieves the following technical effects: by designing one of the lock sleeves to consist of a fixed part 102 and a movable part 103, the movable part 103 can rotate and open relative to the fixed part. This rotatable structure increases the operational flexibility of the lock and makes installation simpler and more convenient. It also has an adjustment mechanism that can be flexibly adjusted according to actual needs to adapt to door panels of different widths. At the same time, the locking mechanism 400, through the cooperation of the rotary combination lock 401 and the bolt 406, provides a highly secure locking method that can be unlocked without carrying a key, making it more convenient.

[0043] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0044] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0045] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
