[0002] Sliding doors and windows are widely used in daily life. As an essential decorative element in modern home décor, their sliding mechanism significantly improves the utilization of interior space compared to ordinary rotating doors and windows. However, since most sliding doors and windows cannot be fully opened, limiting passageway space, people desire a combination of sliding and casement / rotating doors and windows, enabling both partially open sliding and fully open casement / rotating doors and windows. To achieve a fully open sliding and casement / rotating door and window, the sliding track consists of two parts: a fixed track fixed to the upper part of the door / window frame and a movable track fixed to the top of the fixed door / window frame. The sliding door / window must slide from the fixed track to the movable track to overlap with the fixed door / window and rotate. This necessitates a special locking mechanism designed on both the fixed and movable tracks to ensure smooth sliding from the fixed track to the movable track.

[0003] A lock body fixed to the end of a fixed track is a fixed lock body, and a lock body fixed to the end of a movable track is a movable lock body. During use, due to manufacturing errors and the weight of the door or window, vibrations and abnormal noises often occur when the sliding rollers installed on the top of the sliding door leaf pass over the connection between the fixed and movable tracks. This significantly affects the user experience and reduces the lifespan of the sliding rollers, tracks, and lock bodies.

[0018] To explain in detail the technical content, structural features, objectives, and effects of the technical solution, the following description is provided in conjunction with specific embodiments and accompanying drawings.

[0019] like Figures 1 to 4 As shown, this embodiment provides a lock body for sliding doors and windows, including: a movable lock body 1 and an adjusting support wheel 108; The movable lock body 1 is fixed on the moving track 201. One end is tightly connected to the moving track 201, and the other end is engaged with the fixed lock body 205. The movable lock body 1 is provided with a sliding lock tongue 101 and a slide rail. The telescopic end of the sliding lock tongue 101 can extend telescopically into the hanging wheel slide rail 102. The movable lock body 1 on one side of the hanging wheel slide 102 is provided with a mounting groove 103. An adjusting block 104 is provided in the mounting groove 103. An adjusting hole 107 is provided on the movable lock body 1 above and / or below the adjusting block 104. An adjusting bolt is provided in the adjusting hole 107. The adjusting bolt is connected to the adjusting block 104. The adjusting support wheel 108 is rotatably connected to the adjusting block 104.

[0020] In this embodiment, the movable lock body 1 is provided with a sliding latch 101 groove. The sliding latch 101 is spring-loaded into the sliding latch 101 groove. When the movable lock body 1 is engaged with the fixed lock body 205, the sliding latch 101 is compressed, opening the roller slide 102 of the movable lock body 1. At this time, the movable door leaf 207 can slide and pull within the roller slide 102. When the movable lock body 1 and the fixed lock body 205 are separated, the sliding latch 101 is released under the elastic force of the spring, blocking the roller slide 102, thereby preventing the movable door leaf 207 from sliding out of the moving track 201.

[0021] like Figure 2 and Figure 3As shown, adjustment holes 107 are provided on both the upper and lower movable lock bodies 1 of the adjustment block 104. By setting adjustment bolts in the adjustment holes 107 and abutting against the top and bottom surfaces of the adjustment block 104, the height of the adjustment block 104 can be adjusted, thereby adjusting the height of the adjustment support wheel 108 rotatably connected to the adjustment block 104. This allows the adjustment support wheel 108 to lift the sliding hanger 208 when it passes the junction of the movable lock body 1 and the fixed lock body 205, thus avoiding vibration and abnormal noise.

[0022] like Figure 2 As shown, in order to facilitate the installation of the adjustable support wheel 108 and to extend the adjustable support wheel 108 into the hanging wheel slide 102, in this embodiment, the adjusting block 104 is provided with an extension 105, and the adjustable support wheel 108 is rotatably connected to the extension 105.

[0023] like Figure 2 and Figure 3 As shown, in some embodiments, to limit the adjusting block 104 in the lateral direction, a slot 106 is provided on the adjusting block 104, and the plane where the slot 106 is located is on the same plane as the plane where the movable lock body 1 and the door frame of the movable door leaf 207 are connected. This allows the door frame of the movable door to fit precisely into the slot 106 when the movable lock body 1 is engaged with the door frame of the movable door leaf 207, thereby limiting the adjusting block 104 in the lateral direction within the mounting groove 103. This prevents the adjusting block 104 from shifting laterally, which would cause the adjusting support wheel 108 to tilt and fail to support and slide properly.

[0024] Furthermore, in some embodiments, to ensure that the movable lock body 1 and the fixed lock body 205 can be locked simultaneously in both horizontal and vertical directions after mating, thereby further improving the compatibility of the movable lock body 1 and the fixed lock body 205 and reducing abnormal noise and vibration when the sliding roller 208 passes by, the movable lock body is also provided with a positioning rod groove 109, and a positioning slider 110 is provided in the positioning rod groove 109. The top and / or the top of the positioning rod groove 109 is provided with a positioning slider groove 111, and the positioning slider 110 is provided in the positioning slider groove 111 by a spring.

[0025] like Figures 5 to 13 As shown, this embodiment also provides a sliding door and window, including: a door leaf, a moving track 201, a fixed track 203 and a fixed lock body 205, and also includes the lock body for sliding doors and windows as described in any of the above embodiments; The movable lock body 1 is fixedly installed at the end of the moving track 201, and the fixed lock body 205 is fixedly installed at the end of the fixed track 203. The movable lock body 1 and the fixed lock body 205 are adapted to be connected. like Figure 12 and Figure 13As shown, the movable track 201 is provided with a first track 202, and the fixed track 203 is provided with a second track 204. The first track 202 is connected to the second track 204 through the track provided in the roller slide 102 of the movable lock body 1 and the fixed lock body 205. A movable door 207 is also suspended inside the movable track 201. A sliding hanger 208 and a third track are fixedly installed on the top of the movable door 207. The sliding hanger 208 is slidably connected to the first track 202 and the second track 204. The slide opening of the third track is downward, and the adjusting support wheel 108 is slidably connected to the third track.

[0026] In this embodiment, the door leaf is located within the moving track 201. Both the moving track 201 and the fixed track 203 are located within the door frame 211. The fixed track 203 is fixedly connected to the top door frame. The moving track 201 can be rotated open within the door frame. One end of the movable lock body 1 is tightly connected to the moving track 201, and the other end is engaged with the fixed lock body 205. One end of the fixed lock body 205 is tightly connected to the fixed track 203, and the other end is engaged with the movable lock body 1. When the movable lock body 1 and the fixed lock body 205 are engaged, the first track 202 and the second track 204 are connected through the tracks provided in the roller slide 102 of the movable lock body 1 and the fixed lock body 205 to form a complete sliding track. At this time, the movable door leaf 207 suspended in the movable track 201 can be pushed and pulled on the first track 202 and the second track 204. In this embodiment, to avoid vibration and abnormal noise when the sliding roller 208 provided on the top of the movable door leaf 207 passes through the engagement point of the first track 202 and the second track 204, such as... Figure 8 As shown, a third guide rail 209 with a downward-facing slide opening is provided on the top of the movable door leaf 207, and an adjusting support wheel 108 is provided on the movable lock body 1. By adjusting the support wheel 108 to support the third guide rail 209, the sliding hanging wheel 208 is lifted after passing the joint of the first track 202 and the second track 204, thereby avoiding abnormal noise caused by the sliding hanging wheel 208 passing directly through the joint.

[0027] In the above embodiments, such as Figure 7 As shown, the top two ends of the movable door leaf 207 are respectively provided with mounting bases 210, and the sliding caster 208 and the third track are respectively connected to the mounting bases 210.

[0028] In some embodiments, to ensure smoother movement of the movable door lock and maintain the balance of the entire door panel, the adjusting support wheel 108 is positioned below the third track, with its top contacting the slide rail of the third track. The sliding hanging wheel 208 is positioned on the side of the third track away from the adjusting support wheel 108. Alternatively, the first track 202 and the second track 204 can be configured as a single track, with both tracks on the same side of the hanging wheel slide rail 102, effectively reducing the cost and difficulty of setting up a dual track.

[0029] In some embodiments, to ensure that the movable lock body 1 and the fixed lock body 205 can be locked simultaneously in both horizontal and vertical directions after mating, further improving the compatibility of the movable lock body 1 and the fixed lock body 205, and reducing abnormal noise and vibration when the sliding roller 208 passes by, such as... Figure 9 and Figure 10 As shown, the fixed lock body 205 is provided with a positioning rod 206, which is adapted to the positioning rod groove 109 provided on the movable lock body 1 and the positioning slider provided in the positioning rod groove 109. The positioning rod 206 of the fixed lock body can be limited by the positioning rod groove 109 and the positioning slider, so that the movable lock body 1 and the fixed lock body 205 can be locked simultaneously in both horizontal and vertical directions.
