DETAILED DESCRIPTION

[0027] In order to better understand and implement, the technical scheme in the embodiment of the utility model will be clearly and completely described below by combining the drawings in the embodiment of the utility model.

[0028] In the description of the utility model, it is necessary to explain that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the position or location relationship based on the position or location relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the utility model.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0030] The utility model will be described in further detail below in combination with the drawings.

[0031] Please refer to Figures 1 to 7 The embodiment discloses a lock structure for drift door and window, it includes first handle 1, second handle 2, first transmission member 3, lock cylinder 4 and second transmission member 5;First handle 1 is used to set in door and window fan 6, first handle 1 can follow door and window fan 6 synchronous movement;Second handle 2 is used to set in door and window frame 7, when door and window fan 6 relative to door and window frame 7 moves, first handle 1 can be relative to second handle 2 and moves between relatively close position and relatively far position;First transmission member 3 is connected to first handle 1;Lock cylinder 4 is connected to first transmission member 3, under the drive of first handle 1, first transmission member 3 can drive lock cylinder 4 and moves between unlocking position and locking position;Second transmission member 5 is movably arranged in second handle 2, and second transmission member 5 can be relative to second handle 2 and moves between initial position and terminal position;Wherein, when second transmission member 5 is in initial position, second transmission member 5 and first transmission member 3 are separated;When first handle 1 is in relatively close position and second transmission member 5 is in terminal position, second transmission member 5 and first transmission member 3 are transmission connection, under the drive of second handle 2, second transmission member 5 can drive first transmission member 3 to move.

[0032] Specifically, in the embodiment, when first handle 1 is relative to second handle 2 and is in relatively close position, door and window fan 6 is in the state of moving into door and window frame 7;When first handle 1 is relative to second handle 2 and is in relatively far position, door and window fan 6 is in the state of moving out of door and window frame 7.

[0033] The lock structure for the sliding door and window disclosed in the embodiment allows the first handle 1 to be arranged on the inner side of the door and window leaf 6, so as to facilitate the user to perform the normal unlocking or locking operation from the indoor side; and the second handle 2 is arranged on the door and window frame 7 and located on the outer side of the door and window leaf 6. On the one hand, the design of the second handle 2 and the second transmission member 5 realizes the function of unlocking or locking from the outer side of the door and window leaf 6. The user only needs to simply operate the second handle 2 to realize the transmission connection between the second transmission member 5 and the first transmission member 3, and then control the unlocking or locking of the lock cylinder 4. The operation is simple and reliable, greatly improves the convenience and safety of the door and window, and on the other hand, the separation and transmission connection design of the first transmission member 3 and the second transmission member 5 in the lock structure ensures that they are in a separated state when no outdoor operation is performed, so as not to interfere with the normal translation opening and closing of the door and window leaf 6. When the outdoor unlocking or locking is needed, the transmission connection of the two can be realized through simple operation, which is simple and reliable to operate.

[0034] As shown in Figure 4 and Figure 5 , preferably, in the embodiment, the first transmission member 3 is a lock rod, which can rotate around its own axis under the drive of the first handle 1; the second transmission member 5 is a connecting rod, which can move along its own axis between an initial position and an end position; the connecting rod is separated from the lock rod when it is in the initial position; the connecting rod is connected with the lock rod when the first handle 1 is in the relatively close position and the connecting rod is in the end position, and the connecting rod can rotate around its own axis to drive the lock rod to rotate synchronously under the drive of the second handle 2. In this way, on the one hand, the lock rod as the first transmission member 3 can rotate around its own axis under the drive of the first handle 1. This design makes the unlocking and locking operation of the lock cylinder 4 more direct and efficient. At the same time, when the first handle 1 is in the relatively close position and the connecting rod is pushed to the end position, the connecting rod is connected with the lock rod. At this time, the connecting rod can be driven to rotate around its own axis by the second handle 2, thereby driving the lock rod to rotate synchronously, realizing the accurate control of the lock cylinder 4 from the outdoor side. This design ensures the synchronization and consistency of indoor and outdoor operations. On the other hand, the use of the lock rod and the connecting rod as transmission members not only simplifies the complexity of the lock structure, but also improves its reliability and durability. The rotation and movement of the lock rod and the connecting rod are based on simple mechanical principles, reducing the possibility of failure and facilitating subsequent maintenance and repair. On the other hand, the connecting rod is separated from the lock rod when it is in the initial position, ensuring that the door and window leaf 6 will not be interfered during translation. When the door and window leaf 6 is moved to the position and outdoor operation is needed, the connecting rod is pushed to the end position and connected with the lock rod. This design not only ensures the free movement of the door and window leaf 6, but also provides flexibility for outdoor operation.

[0035] It should be noted that in some other embodiments, the first transmission member 3 and the second transmission member 5 can be, but are not limited to, a gear and rack transmission structure or a cam transmission mechanism, etc., which can be selected according to actual needs, and is not limited herein.

In this way, on the one hand, the design of the button member 22 enables the user to achieve the movement of the connecting rod from the initial position to the end position through a simple pressing action, and then connect with the lock rod. This operation method is intuitive and easy to master, which improves the user experience; on the other hand, the introduction of the resilient member 23 ensures that the button member 22 can be automatically reset when it is not pressed, driving the connecting rod back to the initial position, preparing for the next operation. This automatic reset mechanism reduces the user's operation steps and improves the convenience of operation, and only when the user explicitly presses the button member 22, the connecting rod will move to the end position, preventing the lock from being misused due to misoperation or external force interference, ensuring the stability and safety of the lock; on the other hand, the integration of the button member 22 and the resilient member 23 inside the handle body 21 makes the entire lock structure more compact, reducing the occupied space, which is particularly important for door and window design, helping to maintain the aesthetics and functionality of the door and window.
