[0028] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0029] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0031] Please combine the specific Figures 1 to 9 As shown, the utility model discloses a storage type folding door mechanism, including a storage component 1 and a door body component 2. The storage component 1 is preferably a cabinet, and can also be a box. The storage component 1 has a storage chamber 11 for storing clothes, utensils, toys and other items. A storage chamber 12 is arranged on one side of the storage chamber 11, and a storage cavity opening is arranged on the storage component 1. The outside of the storage component 1 is connected to the storage chamber 11 through the storage cavity opening.
[0032] In addition, the door body component 2 has a first door leaf 21 and a second door leaf 22 hinged to the first door leaf 21, and a first limiting member is arranged between the first door leaf 21 and the storage component 1, and the first limiting member is used to constrain the first door leaf 21 to remain stationary during the process of the second door leaf 22 deflecting toward the outside of the storage component 1, and when the storage component 1 is in a fully opened state, the second door leaf 22 and the first door leaf 21 can deflect toward the outside of the storage component 1 and be slidably arranged in the storage chamber 12.
[0033] In this embodiment, the length of the first door leaf 21 and the length of the second door leaf 22 are both smaller than the width of the storage member 1, so that the first door leaf 21 and the second door leaf 22 can be completely stored in the storage chamber 12, so as to avoid the risk of bumping or scratching the first door leaf 21 and the second door leaf 22 partially protruding outside the storage chamber 12. The first rotation axis edge of the first door leaf 21 is defined as the side edge of the first door leaf 21 close to the storage chamber 12, and the first deflection edge of the first door leaf 21 is the side edge of the first door leaf 21 away from the storage chamber 12.
[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 8 As shown, in the process of opening the second door leaf 22, the second door leaf 22 deflects from the storage cavity around the first deflection edge of the first door leaf 21 and toward the outside of the storage component 1 to the first door leaf 21. In this way, the user will be able to avoid the second door leaf 22 in advance during the process of opening the second door leaf 22, thereby ensuring safety when opening the retractable folding door mechanism. At the same time, the user only needs to provide a smaller force or rotational torque to open the second door leaf 22, thereby improving the convenience of opening.
[0035] like Figure 3, Figure 4 , Figure 5 , Figure 8 , Fig. 9 As shown, when the second door leaf 22 contacts and fits against the first door leaf 21, the first door leaf 21 is deflected and opened again. At this time, the first door leaf 21 and the second door leaf 22 are folded and fitted into one, and deflect toward the outside of the storage component 1 around the first rotating axis edge of the first door leaf 21, and finally move toward the storage chamber 12 together.
[0036] In this way, the first door leaf 21 and the second door leaf 22 are folded together and then deflected, which will be able to effectively avoid the problem of pinching the user's hands or clothes that has always existed in traditional folding doors. In addition, the first door leaf 21 and the second door leaf 22 are deflected toward the outside of the storage component 1 after being folded together. The user can still take avoidance measures in advance, thereby greatly improving the safety performance of the retractable folding door mechanism during use.
[0037] Unexpectedly, after the first door leaf 21 and the second door leaf 22 are folded into one, the user can better hold one side of the first deflection edge of the first door leaf 21 to apply a rotational torque to the door body component 2, and the applied rotational torque is small. It is only necessary to drive the first door leaf 21 and the second door leaf 22 to deflect around the first deflection edge, which will greatly improve the convenience of using the retractable folding door mechanism.
[0038] It should be noted that the material used for the door body component 2 is selected according to the stress conditions and the aesthetic requirements of the appearance design, such as wooden door leaves, metal door leaves, glass door leaves, acrylic door leaves, or lightweight plastic door leaves and cloth door leaves.
[0039] From the above, it can be seen that the retractable folding door mechanism can achieve the effect of opening a single door leaf, that is, only opening the second door leaf 22. Compared with the incomplete opening (that is, only the exposed part of the storage cavity) of the traditional folding door, there is no need to push multiple door leaves at the same time, which is more labor-saving, efficient and convenient. The more important effect is that the guide rails and sliders on the traditional folding door are omitted, and the first door leaf 21 and the second door leaf 22 can be folded smoothly and stably, and the retractable folding door mechanism has a simpler structure and is more convenient to assemble, which is conducive to reducing the overall production cost of the retractable folding door mechanism and reducing the cost of subsequent maintenance.
[0040] As a preferred mode of this embodiment, the first limiting member includes a first magnetic device and a first attraction member, wherein the first magnetic device has a first magnet and a first box body, the first magnet is installed inside the first box body, and the first attraction member is an iron sheet or a magnetic strip.
[0041] Furthermore, a first magnetic device is arranged at one of the first door leaf 21 and the storage component 1, and a first suction member is arranged at the other of the first door leaf 21 and the storage component 1. The first magnetic device is suctionally connected to the first suction member, so that the first door leaf 21 remains fixed during the deflection of the second door leaf 22.
[0042] That is, if the first magnetic device is provided on the first door leaf 21, the first magnetic device is preferably installed on the top and / or bottom of the first door leaf 21. When the first door leaf 21 is in a closed state, the first magnetic device magnetically attracts the first suction member, and uses magnetic force to fix the first door leaf 21 on the storage component 1, thereby being able to effectively restrain the first door leaf 21 from being fixed during the deflection of the second door leaf 22.
[0043] If the first magnetic device is provided on the storage component 1, the first magnetic device is preferably installed on the top and / or bottom of the storage component 1 near the storage cavity, and the first door leaf 21 can be fixed on the storage component 1 under the action of magnetic force, thereby being able to well restrain the first door leaf 21 from remaining fixed during the deflection of the second door leaf 22.
[0044] In order to achieve the purpose of the second door leaf 22 deflecting from the storage cavity around the first deflection edge of the first door leaf 21 and toward the outside of the storage component 1 to the first door leaf 21, the inventor provides a preferred solution in which the first door leaf 21 is hingedly connected to the second door leaf 22 via a hinge. The hinge here is a mature door component in the art.
[0045] Among them, the hinge hinge has a first movable part, a second movable part, and a central connecting axis connecting the first movable part and the second movable part. The central axis direction of the central connecting axis is consistent with the extension direction of the first deflection edge. The first movable part of the hinge hinge is bolted to the first door leaf 21, and the second movable part of the hinge hinge is bolted to the second door leaf 22. In this way, the purpose of hinged connection between the first door leaf 21 and the second door leaf 22 can be achieved.
[0046] In order to make the first door leaf 21 and the second door leaf 22 fit more compactly, as a further preferred mode of this embodiment, a hinge embedding groove is provided on the first door leaf 21 and / or the second door leaf 22, and the groove depth of the hinge embedding groove can be selected to match the thickness of the hinge hinge, or the groove depth of the hinge embedding groove can be selected to be greater than the thickness of the hinge hinge, and the hinge hinge is embedded in the hinge embedding groove. In this way, the first door leaf 21 and the second door leaf 22 can fit more compactly.
[0047] As a preferred embodiment of the present embodiment, the retractable folding door mechanism further includes a second limiting member, which is disposed between the second door leaf 22 and the storage component 1. The second limiting member is used to fix the second door leaf 22 on the storage component 1 in a closed state, so as to avoid the second door leaf 22 from shaking due to not being closed tightly, or the dust in the external air from easily entering the storage chamber 11.
[0048] Preferably, the second limiting member includes a second magnetic device and a second attraction member, wherein the second magnetic device has a second magnet and a second box body, the second magnet is installed inside the second box body, and the second attraction member is an iron sheet or a magnetic strip.
[0049] Furthermore, the second magnetic device is disposed on one of the second door leaf 22 and the storage component 1, and the second suction member is disposed on the other of the second door leaf 22 and the storage component 1, and the second magnetic device is suction-connected to the second suction member.
[0050] Specifically, if the second magnetic device is provided on the second door leaf 22, the second magnetic device is preferably installed on the top and / or bottom of the second door leaf 22. When the second door leaf 22 is in a closed state, the second magnetic device magnetically attracts the second suction piece, and uses magnetic force to fix the second door leaf 22 on the storage component 1, thereby being able to well restrain the second door leaf 22 on the storage component 1, ensuring that the retractable folding door mechanism has a good sealing effect.
[0051] If the second magnetic device is provided on the storage component 1, the second magnetic device is preferably installed on the top and / or bottom of the storage component 1 near the storage cavity, and the second door leaf 22 can be fixed on the storage component 1 under the action of magnetic force, thereby being able to well restrain the second door leaf 22 on the storage component 1.
[0052] Of course, the second limiting member can also be a lock body assembly, which is a mature door component in the art, and the lock body assembly is not limited here and its specific structure is not described. The lock body assembly can not only well constrain the second door leaf 22 on the storage member 1, but also ensure the safety of the storage type folding door mechanism for storing valuables.
[0053] It should be noted that the second limiting member can be selected as one of the above two methods, or can be selected as a combination of the above two methods.
[0054] As a preferred method of this embodiment, please refer to Figure 6 and Figure 7As shown, the retractable folding door mechanism also includes a first anti-slip component 31 arranged on the first door leaf 21, and a second anti-slip component 32 arranged on the second door leaf 22. Here, one of the first anti-slip component 31 and the second anti-slip component 32 is a magnetic block / magnetic strip, and the other of the first anti-slip component 31 and the second anti-slip component 32 is a magnetic strip / iron strip. The first anti-slip component 31 and the second anti-slip component 32 are arranged correspondingly, and when the first door leaf 21 is attached to the second door leaf 22, the first anti-slip component 31 and the second anti-slip component 32 are magnetically connected.
[0055] In this way, with the cooperation of the first anti-slip component 31 and the second anti-slip component 32, the first door leaf 21 and the second door leaf 22 can be stably fitted together after being folded together, so that during the process of the first door leaf 21 and the second door leaf 22 being folded together, fitted together and deflected, the second door leaf 22 will not separate from the first door leaf 21, thereby further improving the safety performance of using the retractable folding door mechanism.
[0056] It should also be noted that one of the first anti-slip component 31 and the second anti-slip component 32 is a slot structure, and the other of the first anti-slip component 31 and the second anti-slip component 32 is a bar protrusion. The slot structure is preferably snap-fitted and connected to the bar protrusion. In this way, the first door leaf 21 and the second door leaf 22 can be stably fitted together after being folded together, thereby further improving the safety performance of using the retractable folding door mechanism.
[0057] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
