[0002] A cabinet is a cabinet structure used to store tableware, kitchen utensils and cook in the kitchen. At present, all cabinets on the market are equipped with trays. In order to allow the trays to be freely rotated or stored in and out of the cabinet body, the manufacturer has specially designed a linkage mechanism for supporting the trays, which is convenient for users to cook or store items, thereby greatly saving space.
[0003] However, the linkage mechanism for supporting the tray in the traditional kitchen cabinet generally needs to be provided with two or more supporting points in the cabinet, so that the tray can be stored in the cabinet and extended outside the cabinet through each swing arm in the linkage mechanism.
[0004] However, the installation of the existing tray folding assembly is based on the side panel or pillar of the cabinet, so the support points are mainly concentrated on the side panel and pillar of the cabinet. Therefore, when the tray is subjected to force, since the force is downward, the bottom has no support when the force point is on the side, which can easily lead to an unstable folding structure. Utility Model Content

DETAILED DESCRIPTION
[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] See also Figure 1 and Figure 2The utility model discloses a tray 10 folding assembly, including a tray 10, a buffer 30 and two swing arm 22 mechanisms, wherein the swing arm 22 mechanism includes a support seat 21 and a swing arm 22, and one end of the swing arm 22 is a first mounting end, and the other end of the swing arm 22 is a second mounting end, the first mounting end is rotatably mounted on the support seat 21 through a bearing 24, and the second mounting end is rotatably connected to the bottom end of the tray 10. In addition, one end of the buffer 30 is hinged to the swing arm 22 of one of the swing arm 22 mechanisms, and the other end of the buffer 30 is hinged to the swing arm 22 of the other swing arm 22 mechanism, and the buffer 30 can be linked to stretch or contract when the swing arm 22 swings to provide a buffering force.
[0032] On the basis of the above structure, when using the tray 10 folding assembly of the utility model, the above tray 10 folding assembly can be used in structures such as cabinets, wardrobes and storage cabinets, and the tray 10 can be extended or retracted to facilitate placing or taking out items from the tray 10.
[0033] This embodiment is described by taking the application of the folding assembly of the tray 10 to a cabinet as an example:
[0034] The support bases 21 of the two swing arms 22 of the folding assembly of the tray 10 can be respectively mounted on the bottom plate of the cabinet and spaced apart. Then the second mounting ends of the two swing arms 22 can be rotatably connected to the bottom end of the tray 10, so that when the tray 10 needs to be extended, the tray 10 can be pulled outward, and then the swing arms 22 located relatively outside the tray 10 can swing relative to the bottom plate. At this time, the tray 10 can swing to the first state of half extending out of the cabinet (half extended state, the other half can still be in the storage state) under the action of one of the swing arms 22, and the user can take out or put in the items to be taken.
[0035] When the tray 10 needs to be pulled out completely, the tray 10 can continue to be pulled. After the outer swing arm 22 of the tray 10 rotates outward to the limit, the swing arm 22 can also pull the buffer 30. Under the stretching action of the buffer 30, the other swing arm 22 is driven to rotate outward to the limit position. In this way, the tray 10 can be fully extended to the second state of the cabinet 40, and the user can use all the trays 10 to place or take out items.
[0036] Of course, when the tray 10 needs to be stored, the user can push the tray 10 to the cabinet. When pushing the tray 10, due to the presence of the buffer 30, the relatively outer swing arm 22 can be pushed to swing first, and then the buffer 30 shrinks and pushes the other relatively inner swing arm 22 to swing to its original position. At this time, the tray 10 is in the third state of being completely stored in the cabinet.
[0037] In this embodiment, the swing mechanism is assembled to the bottom plate of the cabinet with the support base 21, and the swing arm 22 is rotatably cooperated with the support base 21 through the bearing 24. In this way, when the swing arm 22 rotates, the fulcrum of the swing arm 22 is supported by the support base 21 and applied to the bottom plate. In this way, the swing structure is more stable and the swinging process is smooth.
[0038] It should be noted that during the process of storing the tray 10 into the cabinet and extending the tray 10 out of the cabinet, the buffer member 30 can play a good buffering role, preventing the user from causing impact damage to the swing arm 22 mechanism due to excessive force when storing the tray 10 or extending the tray 10, thereby improving the structural stability of the swing arm 22 mechanism and extending the service life of the cabinet.
[0039] Furthermore, a first rotating sleeve 222 is provided at the first mounting end, a first rotating column 212 is provided on the support seat 21, and the first rotating sleeve 222 is sleeved on the outside of the first rotating column 212. Based on this structure, the first rotating sleeve 222 and the first rotating column 212 can be rotatably matched through a bearing 24. In this way, when the swing arm 22 rotates relative to the support seat 21, it can be rotatably matched with the first rotating column 212 as the rotating axis, and the bearing 24 is located between the first rotating sleeve 222 and the first rotating column 212, and the rotating structure is more stable.
[0040] Furthermore, the support seat 21 may also include a support base plate 211, and a first rotating column 212 is arranged on the support base plate 211; the outer diameter of the support base plate 211 is larger than the outer diameter of the first rotating sleeve 222, so that when the support seat 21 is assembled to the bottom plate of the cabinet, the support seat 21 is supported by the support base plate 211 to increase the support area, and the rotation cooperation force point of the first rotating sleeve 222 and the first rotating column 212 is applied to the support plate, thereby reducing the force on the bottom plate and stabilizing the support structure.
[0041] Furthermore, the swing arm 22 mechanism in the present embodiment also includes a supporting plate 23, and the supporting plate 23 can be connected to the bottom end of the tray 10, and the bottom end of the supporting plate 23 can be rotatably connected to the second mounting end. In this way, when the tray 10 and the second mounting end of the swing arm 22 are assembled, the tray 10 can be installed on the supporting plate 23, and then the supporting plate 23 and the second mounting end are rotatably matched, thereby increasing the assembly area between the supporting plate 23 and the tray 10, so that the connection surface between the tray 10 and the swing arm 22 is larger, and the structure of the tray 10 is more stable when heavy objects are placed.
[0042] More specifically, a second rotating sleeve 223 may be provided on the second mounting end, a second rotating column 232 may be provided at the bottom end of the supporting plate 23, and the second rotating sleeve 223 may be sleeved outside the second rotating column 232 and may be rotatably engaged through the bearing 24. In this way, when the swing arm 22 rotates relative to the tray 10, the second rotating column 232 may be used as the rotating axis for rotation engagement, and the bearing 24 may be located between the second rotating sleeve 223 and the second rotating column 232, so that the rotation structure is more stable.
[0043] More specifically, a limit plate 231 is provided on the support plate 23, and the limit plate 231 abuts against the swing arm 22 to limit the rotation of the swing arm 22. The limit plate 231 is located on the outside of the support plate 23 relative to the swing arm, so that when the tray 10 is pulled outward and swung, the swing arm 22 on the outside can swing to the limit plate 231 of a support plate 23 on the outside of the tray 10, thereby limiting the swing range of the swing arm 22 on the outside; when the tray 10 is pushed inward, the swing arm 22 on the inside can swing to the limit plate 231 of a support plate 23 on the inside of the tray 10, thereby limiting the swing range of the swing arm 22 on the inside.
[0044] Furthermore, a limit column 221 is provided on the swing arm 22, and a limit hole is provided on the limit plate 231, so that the limit column 221 can be inserted into the limit hole when the swing arm 22 abuts against the limit plate 231. When the tray 10 is swung to be fully extended to the outside of the cabinet, the tray 10 is fully extended (that is, the second state), and there is no restriction on the cabinet structure, so it is easy to shake. Therefore, in order to keep the tray 10 stable when it is extended, the limit column 221 on the external swing arm 22 can be inserted into the limit hole of the corresponding supporting plate 23 to achieve positioning. In this way, when it needs to be swung again, the limit column 221 can be withdrawn from the limit hole.
[0045] When the tray 10 is reset to be completely stored in the cabinet (i.e., the third state), in order to ensure that the tray 10 can be in a stable storage state, the limiting column 221 of the outer swing arm 22 can be inserted into the limiting hole of the limiting piece 231 of the corresponding supporting plate 23 to achieve positioning.
[0046] Furthermore, the buffer member 30 is a cylinder, a cylinder body of the cylinder is hinged to the swing arm 22 of one of the swing arm 22 mechanisms, and a piston rod of the cylinder is hinged to the swing arm 22 of the other swing arm 22 mechanism.
[0047] On the basis of this structure, the cylinder body of the cylinder is the fixed end of the buffer part 30, and the piston rod of the cylinder is the movable end of the buffer part 30. The cylinder plays a buffering role on the swing arm 22 mechanism during the process of storing the tray 10 into the cabinet and turning the tray 10 out of the cabinet, thereby improving the structural stability of the swing arm 22 mechanism and extending the service life of the cabinet.
[0048] Of course, the above-mentioned buffer member 30 can also be implemented by using a damping member in the prior art. When the buffer member 30 is selected as a damping member, the cylinder of the damping member is the fixed end of the buffer member 30, and the piston rod of the damping mechanism is the movable end of the buffer mechanism. The damping member plays a buffering role on the swing arm 22 mechanism during the process of storing the tray 10 into the cabinet and turning the tray 10 out of the cabinet, thereby improving the structural stability of the swing arm 22 mechanism and extending the service life of the cabinet. More specifically, the buffer member 30 can be a damping mechanism such as a hydraulic damper or an oil pressure damper.
[0049] It should also be noted that the buffer member 30 may also be implemented as a spring structure in the prior art.
[0050] Embodiment 2,
[0051] A cabinet comprises a cabinet body 40 and the tray 10 folding assembly in Embodiment 1, wherein a support seat 21 is installed on a bottom plate of the cabinet body 40 .
[0052] The support bases 21 of the two swing arms 22 of the folding assembly of the tray 10 can be respectively mounted on the bottom plate of the cabinet and spaced apart. Then the second mounting ends of the two swing arms 22 can be rotatably connected to the bottom end of the tray 10, so that when the tray 10 needs to be extended, the tray 10 can be pulled outward, and then the swing arms 22 located relatively outside the tray 10 can swing relative to the bottom plate. At this time, the tray 10 can swing to the first state of half extending out of the cabinet (half extended state, the other half can still be in the storage state) under the action of one of the swing arms 22, and the user can take out or put in the items to be taken.
[0053] When the tray 10 needs to be pulled out completely, the tray 10 can continue to be pulled. After the outer swing arm 22 of the tray 10 rotates outward to the limit, the swing arm 22 can also pull the buffer 30. Under the stretching action of the buffer 30, the other swing arm 22 is driven to rotate outward to the limit position. In this way, the tray 10 can be fully extended to the second state of the cabinet 40, and the user can use all the trays 10 to place or take out items.
[0054] Of course, when the tray 10 needs to be stored, the user can push the tray 10 to the cabinet. When pushing the tray 10, due to the presence of the buffer 30, the relatively outer swing arm 22 can be pushed to swing first, and then the buffer 30 shrinks and pushes the other relatively inner swing arm 22 to swing to its original position. At this time, the tray 10 is in the third state of being completely stored in the cabinet.
[0055] It should be noted that the structure of the folding assembly of the tray 10 of this embodiment for the cabinet is the same as that of the folding assembly of the tray 10 in Embodiment 1, and its effects and working principles are the same as those in Embodiment 1, which will not be described in detail here.
[0056] Furthermore, at least two storage cavities are provided in the cabinet 40, and at least two storage cavities are provided with a tray 10 folding assembly, so that the tray 10 supporting the two storage cavities on the cabinet 40 can be extended or retracted by the tray 10 folding assembly to realize flexible placement and retrieval of items.
[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.
