Description

Technical Field

[0001] This utility model belongs to the technical field of doors, and in particular relates to a sliding door. Background Technology

[0002] In home security, sliding doors installed at stairwells are commonly used to isolate pet areas and prevent children from accidentally falling. Current sliding door technologies typically employ a track-based sliding design, with the door panel fixed via a locking mechanism. While these devices are convenient to install and require little space, their safety performance has the following drawbacks:

[0003] Existing sliding doors rely on simple mechanical latches and slots for locking and fixing, which have limited engagement depth and impact resistance. When subjected to dynamic external forces, such as children running and bumping into the door panel or pets scratching and pushing, the contact surfaces of the latches and slots are prone to elastic deformation due to stress concentration, causing the locking structure to loosen or even detach.

[0004] The aforementioned technical defects directly lead to safety hazards in the actual use of sliding doors: when the protection fails, the openness of the stairwell may cause accidents such as children falling or pets falling from the building, and the safety of home security systems needs to be improved.

[0029] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive element, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0030] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0031] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" 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, and 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. Therefore, they should not be construed as limitations on this utility model.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In some descriptions of utility models, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] Reference Figures 1 to 8 This embodiment provides a sliding door, including a door body 1. The door body 1 is provided with a locking structure 2, a limiting component and a sliding component. The door body 1 can be detachably connected to the door frame through the locking structure 2. The limiting component is arranged adjacent to the locking structure 2 and is used to limit the position of the locking structure 2. The sliding component is used to reduce the friction of the sliding door.

[0034] Preferably, the locking structure 2 includes a rotating component 21 and a fixing component 22. The fixing component 22 is connected to the door frame. The rotating component 21 is provided with a slot 211. The rotating component 21 is movably connected to the door body 1 and can rotate relative to the door body 1. When the rotating component 21 rotates to a preset angle, the slot 211 can engage with the fixing component 22 to realize the connection between the door body 1 and the door frame.

[0035] Furthermore, the door body 1 is provided with a pivot 11, and the rotating component 21 is provided with a connecting hole 212, which is hinged to the pivot 11. The rotating component 21 can rotate about the pivot 11 as a fulcrum.

[0036] As can be seen from the attached drawings, the fixing component 22 is designed with a U-shaped structure. The middle part of the fixing component 22 is provided with a mounting hole 221, through which the fixing component 22 can be fixed to the door frame. A connecting post 222 is provided between the two ends of the fixing component 22. The slot 211 can engage with the connecting post 222 to connect the door body 1 to the connector, so that the door body 1 is in a state where it cannot move.

[0037] Preferably, the rotating component 21 has a notch 213, a horizontally extending limiting groove 214 is provided on one side of the notch 213, and a limiting part 215 is formed on the outer side of the limiting groove 214, and the limiting component can slide between the limiting groove 214 and the notch 213.

[0038] Preferably, the door body 1 includes an outer frame 12, which is a hollow square tube structure. The outer frame 12 is provided with a through hole 13, which corresponds to the limiting groove 214. The limiting component includes a limiting block 3 and a toggle member 31. The limiting block 3 is located inside the outer frame 12. One end of the toggle member 31 is connected to the limiting block 3, and the other end extends along the through hole 13 and the limiting groove 214 to the outside of the outer frame 12.

[0039] Specifically, the side of the limiting block 3 facing away from the actuating member 31 has a groove 311, and a nut 312 is provided in the groove 311. The actuating member 31 is a screw. After the screw passes through the limiting block 3, it is locked by the nut 312 to realize the connection between the limiting block 3 and the wave block.

[0040] Understandably, applying a horizontal force to the end of the actuating member 31 exposed on the outer frame 12 causes the actuating member 31 to move the limiting block 3 into the limiting groove 214. The actuating member 31, positioned above the limiting part 215, restricts the upward rotation of the rotating member 21. In this state, even if a child or pet accidentally touches the rotating member 21, it cannot rotate upward to open, and the door body 1 cannot move, enhancing the safety of the sliding door, especially in windy conditions or when pets are nearby, ensuring a secure lock. When it is necessary to open the sliding door, first move the actuating member 31 to the notch 213, then actuate the rotating member 21 to disengage the slot 211 from the fixing part 22, allowing the sliding door to open horizontally.

[0041] Preferably, the sliding assembly includes a first sliding unit 4 and a second sliding unit 5. The first sliding unit 4 is disposed at the bottom of the door body 1, and the second sliding unit 5 is fixedly connected to the wall. The second sliding unit 5 includes a mounting plate 51 and a second sliding wheel 52. There are two second sliding wheels 52 and a gap is reserved between the two second sliding wheels 52. The outer frame 12 passes through the gap.

[0042] The second sliding wheel 52 can provide guidance for the movement of the sliding door, and the first sliding unit 4 can reduce the friction between the sliding door and the ground. By setting the sliding components, the movement of the sliding door is made smoother and more fluid.

[0043] Specifically, the first sliding unit 4 uses rubber wheels. The combination of the top sliding wheel and the bottom rubber wheel ensures that the door body 1 slides smoothly. The bottom rubber wheel reduces friction and protects the ground.

[0044] Furthermore, the door body 1 includes a first outer frame 121, a second outer frame 122, and a third outer frame 123. The first outer frame 121 is located at the top of the door body 1, the second outer frame 122 is located at the bottom of the door body 1, and the two ends of the third outer frame 123 are respectively connected to the first outer frame 121 and the second outer frame 122. The first outer frame 121 is provided with a set of second sliding units 5, and the second outer frame 122 is provided with two sets of second sliding units 5.

[0045] Preferably, the rotating component 21 is provided with a positioning part 216 extending in the horizontal direction.

[0046] Understandably, the movement of the door body 1 drives the rotating component 21 to move. When the positioning part 216 moves to the second sliding unit 5, it cannot pass through the gap of the second sliding unit 5, and the sliding door cannot continue to move. By adjusting the relative position of the second sliding unit 5 and the door body 1, the maximum distance that the sliding door can move can be adjusted to suit different usage scenarios.

[0047] Preferably, the sliding door provided in this embodiment is made of high-strength aluminum alloy material and its surface is treated with anti-corrosion, which can effectively resist the erosion of harsh environments and is suitable for outdoor scenarios, such as courtyard gates and barn doors. Compared with conventional stainless steel protective doors, the sliding door of this embodiment has a wider range of applications.

[0048] It is understood that those skilled in the art can combine various implementation methods in the above embodiments under the guidance of the above examples to obtain technical solutions with multiple implementation methods.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
