[0001] This utility model relates to the field of sliding door technology, and in particular to a sliding door leaf and a sliding door. Background Technology
[0002] Sliding doors are doors that open or close ventilation openings by pushing or pulling the door panels. Because of their sliding opening and closing mechanism, they do not take up extra interior space and do not require the space that needs to be reserved for opening and closing like revolving doors. Therefore, sliding doors are widely used in spaces with limited room. However, a common problem with sliding doors on the market is that the door frame obstructs the view too much, resulting in a less open field of vision. Utility Model Content

[0007] The second plug-in block extends along a second direction; a second mounting groove is opened at one end of the second frame bar near the third frame bar to cooperate with the second plug-in block, and the second plug-in block is inserted into the second mounting groove; a third mounting groove is opened at one end of the third frame bar near the second frame bar to cooperate with the third plug-in block, and the third plug-in block is inserted into the third mounting groove.
[0008] In one embodiment, the third frame bar has a first cut surface at one end near the first frame bar, and the first cut surface extends along a second direction so that the first cut surface can fit against the side wall of the first frame bar near the third frame bar;
[0009] And / or, the third frame strip has a first beveled surface at one end near the second frame strip, and the first beveled surface is inclined at a preset angle when projected along a third direction; the second frame strip has a second beveled surface at one end near the third frame strip, and the second beveled surface is inclined at a preset angle when projected along a third direction; the inclination angle of the first beveled surface is the same as the inclination angle of the second beveled surface, so that the first beveled surface and the second beveled surface can be fitted together.
[0010] In one embodiment, the width of the first frame strip is 40mm to 50mm.
[0011] In one embodiment, the sliding door leaf further includes a wind deflector strip, which is disposed on one side of the sliding door leaf along a third direction.
[0012] This utility model also proposes a sliding door, which includes: a door frame and sliding door panels; the sliding door panels are slidably disposed within the door frame, and the sliding door panels are any of the sliding door panels described above; two sliding door panels are arranged along a third direction, and the two sliding door panels are arranged opposite each other along a first direction, the third direction and the first direction intersect with the second direction; the two sliding door panels have an open position and a closed position in the door frame, and when the two sliding door panels are in the closed position, the two sliding door panels can cover the door frame, and the windproof strips on the two sliding door panels can abut against each other.
[0013] In one embodiment, the door frame includes two supporting frames arranged opposite each other along a first direction, and an upper frame and a lower frame spaced apart along a second direction.

[0032] This utility model proposes a sliding door leaf 100.
[0033] Please see Figures 1 to 8 In one embodiment of this utility model, the sliding door leaf 100 includes: glass 1, mounting frame 2, and first connector 3. The mounting frame 2 surrounds the outer periphery of the glass 1. The mounting frame 2 includes a first frame strip 21 and a second frame strip 22 disposed opposite to each other on both sides of the glass 1 along a first direction, and two third frame strips 23 disposed opposite to each other on both sides of the glass 1 along a second direction. The first frame strip 21 and the second frame strip 22 extend along the second direction, and the third frame strips 23 extend along the first direction. The first direction and the second direction intersect. One end of each third frame strip 23 is connected to the first frame strip 21, and the other end is connected to the second frame strip 22. The first frame strip 21 and the third frame strip 23 are connected by the first connector 3. The first connector 3 includes a mounting plate 31 and a first plug-in block 32 disposed on one side of the mounting plate 31. The mounting plate 31 is connected to the first frame strip 21, and the first plug-in block 32 is connected to the third frame strip 23.
[0034] In this embodiment, the glass 1 is installed inside the mounting frame 2 and can completely cover the ventilation opening of the mounting frame 2; the mounting frame 2 has a first frame strip 21, a second frame strip 22 and a third frame strip 23, wherein the first frame strip 21 and the second frame strip 22 extend along a second direction, which is a vertical direction, and the two third frame strips 23 are arranged along a first direction, which is a horizontal direction; such that the first frame strip 21 and the two third frame strips 23 are all arranged perpendicularly, and the second frame strip 22 and the two third frame strips 23 are all arranged perpendicularly, thereby forming a rectangular frame by the first frame strip 21, the second frame strip 22 and the two third frame strips 23, and the glass 1 has a shape that matches the rectangular frame, so as to facilitate installation in the rectangular frame.
[0035] Understandably, in existing technology, sliding door panels 100 typically only have door handles and other hardware on one side, preventing the frame strip at that location from being made narrower. Furthermore, because the handle and other hardware are installed there, the frame strip needs to bear significant weight, further limiting its narrowness. To ensure the installation strength of the frame strip with the door handle, the connecting parts also require higher-strength corner brackets, which occupy a larger volume. For ease of production, the four corner brackets used in the window sash usually have identical dimensions for mass production. This necessitates reserving a certain installation space for the frame strips connected to the corner brackets, making it difficult to narrow the frame and requiring a larger viewing area.
[0036] In this embodiment, hardware such as door handles are installed on the second frame strip 22. Therefore, the second frame strip 22 needs to have a certain width to support these hardware components. The connectors connected to the second frame strip 22 need to have a certain strength. The two third frame strips 23 connected to the second frame strip 22 also have the same width to match the connectors on the second frame strip 22. The first frame strip 21 does not need to install heavy hardware, so it can be set to be narrower. By using the first connector 3 to connect the first frame strip 21 and the third frame strip 23, the first connector 3 and the third frame strip 23 can be set to different widths. In order to facilitate the production of the frame strip and reduce the weight of the frame strip, the slot is usually a through groove opened along the extension direction of the frame strip. That is, the slots at both ends of the third frame strip 23 have the same size and shape. Therefore, the first connector 3 is set as a structure including a mounting plate 31 and a first plug-in block 32 provided on one side of the mounting plate 31. The first plug-in block 32 is used to match the shape and size of the through groove in the third frame strip 23. The first plug-in block 32 and the mounting plate 31 can be connected by welding or by fasteners. Since the thickness of the mounting plate 31 is much smaller than that of the plug-in block, the first frame strip 21 does not need to have a slot of a certain width to match the plug-in block. The mounting plate 31 can be connected to the side wall of the first frame strip 21, which allows the first frame strip 21 to be set narrower, reducing the light-gathering area occupied and making the sliding door 200 have a wider field of vision.
[0037] The technical solution of this utility model involves setting a glass 1, a mounting frame 2, and a first connecting member 3 in the sliding door leaf 100. The glass 1 is installed in the mounting frame 2, which has a first frame strip 21 and a second frame strip 22 arranged opposite to each other on both sides of the glass 1 along a first direction, and two third frame strips 23 arranged opposite to each other on both sides of the glass 1 along a second direction. The first frame strip 21 is connected to the two third frame strips 23 through the first connecting member 3. The first connecting member 3 includes a mounting plate 31 and a first plug-in block 32 located on one side of the mounting plate 31. The mounting plate 31 connects to the first frame strip 21, and the plug-in block connects to the third frame strip 23. By setting the mounting plate 31, which is relatively thin and relatively small in volume, to connect the first frame strip 21, the first frame strip 21 connected to the mounting plate 31 does not need to reserve too much space for the connecting member. The width of the first frame strip 21 can be set to be relatively narrow, thereby reducing the width of the first frame strip 21, expanding the light-receiving area of the sliding door leaf 100, and making the field of vision of the sliding door 200 wider.
[0038] See Figure 1 , 8 In one embodiment, the mounting plate 31 extends along a second direction, and the side of the mounting plate 31 facing away from the first plug-in block 32 is connected to the first frame strip 21 by fasteners. The first plug-in block 32 extends along a first direction, and the end of the third frame strip 23 near the first frame strip 21 has a first mounting groove that mates with the first plug-in block 32, into which the first plug-in block 32 is inserted. In this embodiment, the mounting plate 31 extends along a second direction, and the first plug-in block 32 extends along a first direction. One end of the first plug-in block 32 is connected to the middle of one side of the mounting plate 31, and the other end is inserted into the first mounting groove corresponding to the third frame strip 23. The side of the mounting plate 31 facing away from the first plug-in block 32 is fixed to one side wall of the first frame strip 21 and secured by fasteners. The fasteners are symmetrically arranged on both sides of the first plug-in block 32 to balance the force on the first connector 3 and increase its connection stability. The first mounting groove has a contour shape that matches the outer contour of the first plug-in block 32 to limit the position of the first plug-in block 32 in the first mounting groove.
[0039] See Figure 1 , 7In one embodiment, the sliding door leaf 100 further includes a second connector 4, through which the second frame strip 22 and the third frame strip 23 are connected; the second connector 4 includes a second plug-in block 41 and a third plug-in block 42 connected to each other, the second plug-in block 41 being connected to the second frame strip 22, and the third plug-in block 42 being connected to the third frame strip 23; the second plug-in block 41 extends along a second direction; a second mounting groove is formed at one end of the second frame strip 22 near the third frame strip 23, which mates with the second plug-in block 41, and the second plug-in block 41 is inserted into the second mounting groove; a third mounting groove is formed at one end of the third frame strip 23 near the second frame strip 22, which mates with the third plug-in block 42, and the third plug-in block 42 is inserted into the third mounting groove.
[0040] In this embodiment, the second connector 4 is used to connect the wider second frame strip 22 and the third frame strip 23. The second connector 4 includes a second plug-in block 41 and a third plug-in block 42 integrally formed or interconnected. The second plug-in block 41 and the third plug-in block 42 are symmetrically arranged and have the same cross-sectional shape and size. Since the third plug-in block 42 and the first plug-in block 32 are both located on the third frame strip 23, for ease of production, the third mounting groove and the first mounting groove on the third frame strip 23 are usually connected to form a through groove penetrating the third frame strip 23. Therefore, the cross-sectional shape of the third plug-in block 42 is set to the same size and shape as the cross-sectional shape of the first plug-in block 32 to match the openings with the same shape at both ends of the through groove. In this embodiment, to further facilitate production, the cross-sectional shapes of the first plug-in groove, the second plug-in groove, and the third plug-in groove are all set to rectangular shapes to more easily accommodate the plug-in blocks.
[0041] In one embodiment, the third frame strip 23 has a first cut surface at one end near the first frame strip 21, the first cut surface extending along a second direction, so that the first cut surface can fit against the side wall of the first frame strip 21 near the third frame strip 23; and / or, the third frame strip 23 has a first oblique cut surface at one end near the second frame strip 22, the first oblique cut surface being inclined at a preset angle when projected along a third direction; the second frame strip 22 has a second oblique cut surface at one end near the third frame strip 23, the second oblique cut surface being inclined at a preset angle when projected along a third direction; the inclination angle of the first oblique cut surface is the same as the inclination angle of the second oblique cut surface, so that the first oblique cut surface and the second oblique cut surface can fit together. The second frame strip 22 and the third frame strip 23 have the same width, and their beveled surfaces can fit together. Therefore, the beveled surface at the junction of the second frame strip 22 and the third frame strip 23 is set at 45°. The first frame strip 21 is narrower, so the beveled surface of the third frame strip 23 near the end of the first frame strip 21 is set as a 90° bevel extending vertically to fit with the side wall of the first frame strip 21. By providing the first connector 3 and the second connector 4, the first connector 3 can be used to adapt and connect two frame strips that meet with a 90° beveled surface, and the second connector 4 can be used to adapt and connect two frame strips that meet with a 45° beveled surface, thus enabling the sliding door leaf 100 to adapt to different connection structures.
[0042] In one embodiment, the width of the first frame strip 21 is 40mm to 50mm. In this embodiment, the width of the first frame strip 21 is set to be greater than 40mm and less than 42mm, so as to make the frame strip narrower while ensuring that the frame strip meets the strength production requirements. The second frame strip 22, since it needs to accommodate hardware such as door handles, requires a width of at least 100mm. The second frame strip 22 and the third frame strip 23 that are connected to it also require a width of at least 100mm, which is the frame strip width of the sliding door leaf 100 in the prior art.
[0043] See Figure 1 , 2 5; In one embodiment, the sliding door leaf 100 further includes a wind deflector strip 5, which is disposed on one side of the sliding door leaf 100 along a third direction. Since the sliding door leaf 100 is usually provided with at least two leaves, in order not to affect the relative sliding of the leaves, the sliding trajectories of adjacent sliding door leaves 100 are usually staggered, so that there is a certain gap between adjacent leaves. In order to prevent air leakage from the gap, wind deflector strips 5 are usually provided on opposite sides between two adjacent leaves. The two wind deflector strips 5 can completely cover the gap, thereby preventing air leakage.
[0044] See Figure 2-8The present invention also proposes a sliding door 200, which includes a door frame 10 and a sliding door leaf 100. The specific structure of the sliding door leaf 100 is as described in the above embodiments. Since the sliding door leaf 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here. The sliding door 200 includes a door frame 10 and a sliding door leaf 100. The sliding door leaf 100 is slidably disposed within the door frame 10, and the sliding door leaf 100 is any of the sliding door leaf 100 described above. Two sliding door leaves 100 are arranged along a third direction, and the two sliding door leaves 100 are arranged opposite each other along a first direction. The third direction and the first direction intersect with the second direction. The two sliding door leaves 100 have an open position and a closed position in the door frame 10. When the two sliding door leaves 100 are in the closed position, the two sliding door leaves 100 can cover the door frame 10, and the windproof strips 5 on the two sliding door leaves 100 can abut against each other.
[0045] In this embodiment, the two sliding door panels 100 are arranged along a third direction so that their movement trajectories are staggered, and their sliding motion does not interfere with each other. Simultaneously, the two sliding door panels 100 are arranged opposite each other along a first direction, so that the wind deflector strips 5 on the two door panels are positioned between them and can abut against each other. The two wind deflector strips 5 on the two door panels can cooperate to cover the gap between them, preventing air from entering after the doors are closed. An anti-collision strip is also provided on the side where the two wind deflector strips 5 abut against each other. The anti-collision strip is used to prevent impact caused by the two sliding door panels 100 being pulled in opposite directions, thereby extending the service life of the sliding door 200.
[0046] In one embodiment, the door frame 10 includes two supporting frame bodies 101 arranged opposite each other along a first direction, and an upper frame body 102 and a lower frame body 103 spaced apart along a second direction. The upper frame body 102 and the lower frame body 103 extend along the first direction, and the two supporting frame bodies 101 extend along the second direction. The sliding door leaf 100 is slidably installed in the door frame 10 via the upper frame body 102 and the lower frame body 103. The supporting frame bodies 101 extend along the second direction, which is a vertical direction, while the upper frame bodies 102 and the lower frame bodies 103 extend along the first direction, which is a horizontal direction. This allows the supporting frame bodies 101 to support the upper frame body 102 at the top of the door frame 10, thereby supporting the upper frame body 102 to a certain height. The upper frame 102, the lower frame 103, and the supporting frame 101 enclose a rectangular door frame 10, so that the sliding door leaf 100 can be slidably installed in the frame for opening and closing.
[0047] See Figure 2 , 6 In one embodiment, the lower frame 103 is provided with a guide rail 1031 on the side near the sliding door leaf 100. The guide rail 1031 extends along the length direction of the lower frame 103. The sliding door leaf 100 is provided with a roller 6 on the side near the guide rail 1031. The sliding door leaf 100 is slidably connected to the guide rail 1031 via the roller 6. The cooperation of the guide rail 1031 and the roller 6 reduces the friction when the sliding door leaf 100 slides in the door frame 10, thereby facilitating the opening and closing of the sliding door 200. At least two rollers 6 are spaced apart along a first direction. Each roller 6 is rotatably connected to the bottom of the sliding door leaf 100 via a connector and rolls along the first direction.
[0048] In one embodiment, the sliding door leaf 100 has a guide groove 7 on the side near the upper frame 102, and the door frame 10 has a guide block 1021 on the side near the guide groove 7. The guide block 1021 can be inserted into the guide groove 7 and is slidably connected to the guide groove 7. The guide groove 7 is used to guide the sliding door 200 when it moves, so that the sliding door leaf 100 can slide along a preset trajectory in the door frame 10 during sliding, preventing the door leaf from detaching from the door frame 10. Both the guide groove 7 and the guide block 1021 extend along a first direction, and the guide groove 7 and the guide block 1021 have cross-sectional shapes that can cooperate with each other, so that the guide block 1021 can be fitted into the guide groove 7.
[0049] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
