Description

Technical Field

[0001] This invention relates to the field of furniture, and more particularly to a storage cabinet with a concealed expansion structure. Background Technology

[0002] Storage cabinets are common pieces of furniture in people's daily lives, serving the purpose of storing items. In modern life, living spaces are sometimes quite compact, and people have placed higher functional demands on storage cabinets. For example, they also hope that storage cabinets can have a tabletop function. In traditional technology, the size of the storage cabinet tabletop cannot be adjusted, making it unable to cope with changing spatial situations. Summary of the Invention

[0003] The purpose of this invention is to provide a storage cabinet with an invisible expansion structure that allows the desktop to be unfolded and folded.

[0004] The technical solution of the present invention is as follows:

[0005] A storage cabinet with a concealed expansion structure includes a main cabinet and sub-cabinets.

[0006] The main cabinet includes a front panel, a rear panel, a right side panel, and a top panel. The bottom of the top panel is fixed with a front positioning plate for inserting vertically into the upper part of the front panel and a rear positioning plate for inserting vertically into the upper part of the rear panel.

[0007] A mother cabinet loading entrance is formed between the left ends of the front side panel and the rear side panel of the mother cabinet, allowing the sub-cabinets to pass through and be loaded into the inner cavity of the mother cabinet.

[0008] The sub-cabinet includes a left side panel, a right side panel, a front side panel, and a top panel. The top panel is fixed to the top of the left side panel, right side panel, and front side panel. The sub-cabinet also contains at least one layer of partitions. The rear of the sub-cabinet is open.

[0009] A support plate is hinged to the right side of the sub-cabinet. A support plate stop is provided at the end of the support plate away from the hinge. When the sub-cabinet moves to the right, it is inserted into the inner cavity of the mother cabinet. At the same time, the support plate flips over through the gap between the top plate and the right side plate of the mother cabinet to the right side of the right side plate of the mother cabinet. The top plate of the mother cabinet falls onto the first position on the top plate of the sub-cabinet.

[0010] The sub-cabinet moves to the left and moves to the left side of the mother cabinet. At the same time, the support plate edge and the upper part of the right side plate of the mother cabinet stop together, and the top plate of the mother cabinet falls on the support plate. The second working position is where the top plate of the mother cabinet is flush with the upper part of the top plate of the sub-cabinet.

[0011] Furthermore, the bottom of the sub-cabinet is equipped with wheels that have a braking mechanism.

[0012] Furthermore, in the first workstation, the support edge contacts and engages with the right side of the right side panel of the mother cabinet, causing the support plate to be in a vertical position.

[0013] Furthermore, the front panel of the mother cabinet is threaded with a front clamping screw for tightening the front positioning plate; the rear panel of the mother cabinet is threaded with a rear clamping screw for tightening the rear positioning plate.

[0014] Furthermore, the top of the front panel of the mother cabinet is provided with a front panel positioning groove for inserting the front positioning plate in the vertical direction, and the top of the rear panel of the mother cabinet is provided with a rear panel positioning groove for inserting the rear positioning plate in the vertical direction. The left side of the rear panel positioning groove extends to the left side of the rear panel of the mother cabinet, so that the rear panel of the mother cabinet can move left and right relative to the rear positioning plate. The front side of the rear panel of the mother cabinet is provided with a partition guide groove for guiding and cooperating with the rear end of the cabinet partition in the left and right direction.

[0015] Furthermore, when the sub-cabinet is in the first working position, the rear panel of the mother cabinet is directly behind the front panel of the mother cabinet, and the rear panel of the mother cabinet is used to cover the rear of the sub-cabinet; when the sub-cabinet is in the second working position, the partition guide groove and the cabinet partition guide movement cooperate, and the rear panel of the mother cabinet moves to the rear of the sub-cabinet. The rear of the mother cabinet is normally open to avoid the legs of the user.

[0016] The beneficial effects of this application are as follows: The storage cabinet in this invention can be expanded according to the available space. When the available space is relatively small, the sub-cabinet is moved from left to right into the inner cavity of the main cabinet. The support plate flips over through the gap between the top plate and the right side plate of the main cabinet to the right side of the right side plate of the main cabinet. At this time, the top plate of the main cabinet rests on the top plate of the sub-cabinet, and the top plate of the main cabinet can be used as a desktop while the sub-cabinet is hidden. When the available space is relatively large, the sub-cabinet can be moved from right to left out of the inner cavity of the main cabinet until the support plate edge stops at the top of the right side plate of the main cabinet. At this time, the sub-cabinet moves to the left side of the main cabinet, and the top plate of the main cabinet is moved downwards to the top of the support plate. The bottom of the main cabinet rests on the support plate, and the top of the top plate of the main cabinet and the top of the sub-cabinet are flush. The top surfaces of the sub-cabinet and the top plate of the main cabinet are used together as a desktop. Attached Figure Description

[0027] The features and performance of the present invention will be further described in detail below with reference to embodiments.

[0028] A specific embodiment of a storage cabinet with a concealed expansion structure in this invention is as follows: Figures 1-6 As shown,

[0029] It includes a mother cabinet 2 and a daughter cabinet 1. The mother cabinet 2 includes a front side panel 2-5, a rear side panel 2-3, a right side panel 2-2, and a top panel 2-1. The front side panel 2-5 and the right side panel 2-2 are fixed together. The bottom of the top panel 2-1 is fixed with a front positioning plate 8 for inserting into the upper end of the front side panel 2-5 in the vertical direction and a rear positioning plate 7 for inserting into the upper end of the rear side panel 2-3 in the vertical direction.

[0030] In this embodiment, the top of the front panel 2-5 of the mother cabinet is provided with a front panel positioning groove 12 for inserting the front positioning plate 8 in the vertical direction, and the top of the rear panel 2-3 of the mother cabinet is provided with a rear panel positioning groove 11 for inserting the rear positioning plate 7 in the vertical direction. The left side of the rear panel positioning groove 11 extends to the left side panel surface of the rear panel 2-3 of the mother cabinet, allowing the rear panel 2-3 of the mother cabinet to move left and right relative to the rear positioning plate 7. That is, the top panel 2-1 of the mother cabinet can move up and down relative to the rear panel 2-3 of the mother cabinet, and the rear panel 2-3 of the mother cabinet can also move left and right relative to the top panel 2-1 of the mother cabinet. The top panel 2-1 of the mother cabinet cannot move left and right relative to the front panel 2-5 of the mother cabinet, and can only move up and down.

[0031] The front panel 2-5 of the main cabinet is threaded with a front clamping screw 10 for tightening the front positioning plate 8; the rear panel 2-3 of the main cabinet is threaded with a rear clamping screw 9 for tightening the rear positioning plate 7. After loosening the clamping screws, the top panel 2-1 of the main cabinet can move up and down; after tightening the clamping screws, the top panel 2-1 of the main cabinet can move up and down relative to the front panel 2-5 and the rear panel 2-3 of the main cabinet.

[0032] A mother cabinet loading port is formed between the left ends of the front side panel 2-5 and the rear side panel 2-3 of the mother cabinet, allowing the sub-cabinet 1 to pass through and be loaded into the inner cavity of the mother cabinet 2.

[0033] Sub-cabinet 1 includes a left side panel 1-2, a right side panel 1-4, a front side panel 1-5, and a top panel 1-1 fixed together. The top panel 1-1 is fixed to the top of the left side panel 1-2, the right side panel 1-4, and the front side panel 1-5. Sub-cabinet 1 has two layers of partitions 1-3, which divide the interior of sub-cabinet 1 into three storage spaces, each of which can be used to place corresponding objects. The rear of sub-cabinet 1 is open.

[0034] A support plate 4 is hinged to the right side of the sub-cabinet 1 via a hinge 6. A support plate stop 5 is provided at the end of the support plate 4 away from the hinge 6. During the movement of the sub-cabinet 1 to the right, it is inserted into the inner cavity of the mother cabinet 2. At the same time, the support plate 4 flips to the right side of the right side plate 2-2 of the mother cabinet through the gap between the top plate 2-1 and the right side plate 2-2 of the mother cabinet. Meanwhile, the top plate 2-1 of the mother cabinet falls onto the first working position on the top plate 1-1 of the sub-cabinet.

[0035] During the leftward movement of the sub-cabinet 1, it moves to the left side of the mother cabinet 2. At the same time, the support plate edge 5 and the upper end of the right side plate 2-2 of the mother cabinet stop and cooperate. The top plate 2-1 of the mother cabinet rests on the support plate 4, and the top end of the top plate 2-1 of the mother cabinet is flush with the upper end of the top plate 1-1 of the sub-cabinet.

[0036] In this embodiment, the bottom of the sub-cabinet 1 is provided with a traveling wheel 3 with a braking structure. The traveling wheel 3 with a braking structure is the prior art and will not be described in detail here.

[0037] In the first working position, the support edge 5 contacts and engages with the right side of the right side panel 2-2 of the mother cabinet, so that the support plate 4 is in a vertical position. The first support plate 4 is provided with multiple hanging holes. In the first working position, the first support plate 4 can be used to hang some other items, thereby increasing the practicality of the product.

[0038] The front side of the rear panel 2-3 of the mother cabinet is provided with a partition guide groove 2-4 for guiding and moving with the rear end of the cabinet partition in the left and right direction. When the sub-cabinet 1 is in the first working position, the rear panel 2-3 of the mother cabinet is located directly behind the front panel 2-5 of the mother cabinet, and the rear panel 2-3 of the mother cabinet is used to cover the rear side of the sub-cabinet 1. When the sub-cabinet 1 is in the second working position, the partition guide groove 2-4 is guided and moved with the cabinet partition, and the rear panel 2-3 of the mother cabinet moves to the rear side of the sub-cabinet 1. The rear side of the mother cabinet 2 is normally open to avoid the legs of the user.

[0039] Specifically, the rear end of the cabinet partition is provided with convex and concave partition edges 13 on the upper and lower sides respectively. The partition guide groove 2-4 has a guide groove that matches the partition edge 13. Therefore, the cross-section of the entire partition guide groove 2-4 is "T" shaped. The partition edge 13 on the upper side of the cabinet partition has two functions: 1. It can prevent small objects from rolling off the cabinet partition; 2. It can match the guide groove on the partition guide groove 2-4 to prevent the rear side panel 2-3 of the mother cabinet from coming off the rear side of the child cabinet 1.

[0040] As shown in Figure 6, the length of the right side panel 1-4 of the sub-cabinet is shorter than the length of the left side panel 1-2 of the sub-cabinet. This allows the rear side panel 2-3 of the mother cabinet to move smoothly from the side of the mother cabinet 2 to the side of the sub-cabinet 1.

[0041] The storage cabinet in this invention can be expanded according to the available space. When the available space is small, the sub-cabinet 1 is moved from left to right into the inner cavity of the main cabinet 2. The support plate 4 flips over through the gap between the top plate 2-1 and the right side plate 2-2 of the main cabinet to the right side of the right side plate 2-2. At this time, the top plate 2-1 of the main cabinet rests on the top plate 1-1 of the sub-cabinet, and the top plate 2-1 of the main cabinet can be used as a desktop, while the sub-cabinet 1 is hidden. When the available space is large, the sub-cabinet 1 can be moved from right to left out of the inner cavity of the main cabinet 2 until the support plate edge 5 stops at the top of the right side plate 2-2 of the main cabinet. At this time, the sub-cabinet 1 moves to the left side of the main cabinet 2, and the top plate 2-1 of the main cabinet is moved downwards to the top of the support plate 4. The bottom of the main cabinet 2 is supported on the support plate 4. The top surface of the sub-cabinet top panel 1-1 is flush with the top surface of the sub-cabinet top panel 1-1 and the top surface of the mother cabinet top panel 2-1 are used together as the tabletop.

[0042] Furthermore, when the sub-cabinet 1 is in the second work position, if the rear side panel 2-3 of the mother cabinet is still directly behind the front side panel 2-5 of the mother cabinet, the presence of the rear side panel 2-3 will affect the user's legs. Therefore, in this invention, the rear side panel 2-3 of the mother cabinet can be pushed to the left. Before the upper end of the rear side panel 2-3 of the mother cabinet is completely separated from the rear positioning plate 7, the partition guide groove 2-4 on the rear side panel 2-3 of the mother cabinet will cooperate with the rear end guide of the cabinet partition on the sub-cabinet 1. This allows the rear side panel 2-3 of the mother cabinet to be moved smoothly to the rear side of the sub-cabinet 1. On the one hand, this forms a shield for the sub-cabinet partition 1-3, creating a "cabinet door" that can move left and right, preventing dust from entering the storage space. On the other hand, it opens up the rear side of the mother cabinet 2, allowing the user's legs to reach into the inside of the mother cabinet 2 for easier use.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
