Description

Technical Field

[0001] The invention relates to the field of sliding doors and windows, and in particular to a lock body for sliding doors and windows and the sliding doors and windows. Background Art

[0002] In daily life, the use of sliding doors and windows has become very common. As a kind of decorative doors and windows that are essential for modern home decoration, sliding doors and windows can greatly improve the utilization rate of indoor space compared with ordinary rotating doors and windows because they are opened by sliding. However, since ordinary sliding doors and windows cannot be fully opened, the passage position is limited. People hope to combine sliding doors and windows with casement and rotating doors and windows, so that they can not only achieve sliding and half-opening doors and windows, but also achieve fully opening doors and windows after casement and rotation. When realizing doors and windows that can be pushed and pulled and can be fully opened by casement and rotation, the sliding track of the sliding doors and windows includes two parts: one part is a fixed track fixed to the upper part of the door and window frame, and the other part is a moving track fixed to the top of the fixed door and window frame. Since the sliding doors and windows must slide to the moving track with the help of the fixed track, they can overlap with the fixed doors and windows and rotate. This requires that a special lock body must be designed on the fixed track and the moving track to allow the sliding doors and windows to slide smoothly from the fixed track to the moving track.

[0003] Chinese patents CN110905300A, CN211144070U, and CN214996814U respectively disclose a lock body, which is a key component that can realize the pushing and pulling and rotating and opening of sliding doors and windows. Although this type of lock body is designed to limit the relative horizontal position of the movable body and the fixed body through the positioning rod and the positioning rod groove, in the actual production process, due to the limitation of the process level, the actual processed things have errors, resulting in the products produced are often not level, with an error of about 0.3 mm. Although this error does not affect the use of the product, there will be obvious vibration, setbacks and abnormal noise when the hanging wheel passes through the connection point, which will have a fatal impact on the damage to the hanging wheel and the durability of the product in the long run, and the consumer experience is also very poor.

[0019] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0020] Please also read Figures 1 to 8 As shown in the figure, this embodiment provides a lock body for sliding doors and windows, including: The fixed body 1 is fixed on the fixed track 10, one end of which is tightly combined with the fixed track 10, and the other end of which moves in coordination with the movable body 2; The movable body 2 is fixed on the movable track 11, one end of which is tightly combined with the movable track 11, and the other end of which moves in coordination with the fixed body 1; The track groove 301 of the fixed body 1 and / or the movable body 2 is provided with a track extension part 302, and the track groove of the movable body and / or the fixed body is provided with a track docking groove 303 adapted to the track extension part. In the implementation process of this embodiment, since the track extension part 302 and the track docking groove 303 adopt a connection position to extend a part of the track forward by a certain length, and at the same time require that the extended parts do not interfere with each other and complement each other, to form a new partial complete track, the problem of excessive smooth connection between the tracks is effectively solved. In this embodiment, the track extension part 302 and the track docking groove 303 on the fixed body and / or the movable body include only one end provided, so as to cooperate with each other, so that the hanging wheel can smoothly pass through the connection between the fixed body and the movable body.

[0021] like Figure 4 As shown, the upper surface of the track extension part 302 is provided with an inclined surface 304 extending downward; in this embodiment, the inclined surface 304 includes a straight surface inclined downward, and can also be an arc-shaped surface inclined downward. By setting the upper surface of the track extension part 302 as an inclined surface inclined downward, the part away from any main body will be relatively small, and since the track extension parts overlap, there will be Figure 2As shown, the hard transition position itself will be turned into a gentle slope. The hanging wheel will first go downhill at this position, and then go uphill slowly after encountering the opposite track, and then return to the normal track height. In this operation process, as long as the height difference of the slope is controlled to be greater than the production error, the abnormal noise caused by the hanging wheel passing can be greatly reduced or even eliminated. In this embodiment, the height difference between the front end of the track extension and the horizontal plane is h, and the range of h is 0.1mm≤h≤1mm; it can effectively solve the abnormal noise caused by processing errors during processing, especially the processing error is between 0.1mm and 1mm.

[0022] like Figure 5 As shown, the fixed body or the movable body is provided with a sliding lock tongue groove 401, which is connected to the hanging wheel slide 12 of the fixed body or the movable body. A sliding lock tongue 402 is provided in the sliding lock tongue groove 401, and the end of the sliding lock tongue 402 is telescopically extended to the hanging wheel slide 12. In this embodiment, the sliding lock tongue groove 401 is used to limit the movement direction and movement distance of the sliding lock tongue 402 on the fixed body or the movable body, so as to achieve the designed action of opening or closing the hanging rail slide. The hanging wheel slide 12 is used to hang or bear the load of the door leaf. It is a part of the fixed track and the movable track. When the fixed body and the movable body are tightly combined, the hanging wheel slide 12 is connected, otherwise they are separated and closed. Specifically, the closing and connection of the hanging wheel slide 12 is achieved by the sliding lock tongue 402. When the fixed body and the movable body are matched, the sliding lock tongue 402 is compressed into the sliding lock tongue groove. At this time, the hanging wheel slide 12 is connected. When the fixed body and the movable body are separated, since a reset spring 403 is arranged along the movement direction of the sliding lock tongue 402 in the sliding lock tongue groove 401, one end of the reset spring 403 is connected to the sliding lock tongue groove 401, and the other end is connected to the sliding lock tongue 402. Under the action of the reset spring 403, the sliding lock tongue 402 pops out to close the hanging wheel slide 12.

[0023] like Figure 5 and Figure 6 , Figure 7As shown, in some embodiments, a trigger rod 501 is provided on the movable body or the fixed body, and the trigger rod 501 cooperates with the sliding lock tongue 402. By providing the trigger rod 501 on the movable body or the fixed body, and cooperating with the sliding lock tongue provided on the fixed body or the movable body, the purpose of squeezing the sliding lock tongue is achieved; in different embodiments, when the sliding lock tongue cannot contact the trigger rod in the spatial position, the purpose of squeezing the sliding lock tongue can also be achieved by providing a triggered rod 404 on the sliding lock tongue, and the trigger rod 501 and the triggered rod 404 make cooperative movements. In this embodiment, the trigger rod 501 does not necessarily refer to a rod-shaped object, and it includes any structure for squeezing the sliding lock tongue. For example, in this embodiment, the positioning rod groove and its front end portion act as a trigger rod, and the effect of compressing the sliding lock tongue is achieved during the matching process of the fixed body and the movable body. Of course, in different embodiments, the positioning rod or the stop rod can also act as a trigger rod.

[0024] like Figure 5 and Figure 6 , Figure 7 As shown, in some embodiments, a positioning rod 601 is provided on the fixed body or the movable body, and a positioning rod groove 602 is provided on the movable body or the fixed body along the moving direction of the positioning rod. The positioning rod 601 is adapted to be connected with the positioning rod groove 602. One positioning rod can be provided, or two or more positioning rods can be provided as required, which are used to limit the relative horizontal position of the fixed body and the movable body after being matched. In some embodiments, a stop rod 701 or a positioning rod 601 is provided on the fixed body or the movable body, and a stop slider 702 adapted to the stop rod 701 or the positioning rod 601 is provided on the movable body or the fixed body. The stop rod 701 or the positioning rod 601 and the stop slider 702 are used to limit the relative vertical position of the fixed body and the movable body after being matched. In this embodiment, a stop slider groove 703 is provided at the setting position of the stop slider 702, and the stop slider 702 is arranged in the stop slider groove 703 through a reset spring, and the resilience of the reset spring here is greater than the resilience of the reset spring 403 of the sliding lock tongue 402. In various embodiments, the stop rod may be replaced by a positioning rod due to space requirements.

[0025] By limiting the relative horizontal and vertical positions of the fixed body and the movable body, the two bodies can be locked in the horizontal and vertical directions at the same time, making the connection tighter, reducing the gap between the bodies, avoiding shaking and noise. In this embodiment, the positioning rod or the stop rod can replace the trigger rod to squeeze the sliding lock tongue; like Fig. 9 and Fig.10 , Fig.11As shown, in some embodiments, a sliding door and window is further provided, comprising a lock body for sliding door and window as described in any one of the above embodiments, and also comprising a door frame 8 and a door leaf 9, the door leaf being suspended in the suspension wheel tracks of the fixed track 10 and the movable track 11 through a suspension wheel, the fixed track and the movable track being connected to the door frame, and a track docking groove 303 or a track extension 302 matching the track extension 302 or the track docking groove 303 is provided on the track groove 301 of the fixed track and / or the movable track. By providing a track docking groove or a track extension matching the track extension or track docking groove provided on the fixed body 1 or the movable body 2 on the fixed track and / or the movable track, it is effectively achieved that the suspension wheel can pass smoothly when passing through the connection between the fixed body 1 and the fixed track 10, and the connection between the movable body 2 and the movable track 11. Similarly, a downwardly inclined slope 304 can be provided on the upper surface of the track extension portion provided on the fixed track and / or the movable track. The slope 304 includes a straight surface or a curved surface. The slope here cooperates with the slope provided on the fixed body or the movable body, thereby further reducing or eliminating the noise caused by the passing of the hanging wheel, so that the hanging wheel can pass more smoothly.
