[0001] This utility model relates to the field of sofa technology, and in particular to a detachable sofa that can reduce storage and transportation space. Background Technology

[0002] A sofa is a common type of furniture, mainly used for people to sit, lie down or rest. It is usually composed of a frame, filling and outer fabric (or leather, velvet, etc.), and is both comfortable and practical. Demountable sofas can be disassembled into multiple small parts, taking up little space during transportation and reducing transportation costs, making them especially suitable for residential environments where elevator space is limited or stairs are difficult to move.

[0003] Chinese Patent Publication No. CN221012596U discloses a sofa assembly / disassembly structure, including two sets of back panels, side panels, front panels, and three sets of seat cushion frames. The two sets of back panels and two sets of front panels are respectively spliced ​​left and right. The two sets of side panels are respectively set on both sides of the back panels and front panels. The back panels and front panels are symmetrically arranged front and back. The three sets of seat cushion frames are arranged horizontally between the two sets of back panels and front panels. The bottom of the middle seat cushion frame is connected to a bracket. The bottom of the side panels and the bracket are fixedly connected to the legs supporting the ground. The front of the back panel is staggered with reinforcing vertical ridges and reinforcing horizontal ridges. This utility model modularizes the existing sofa body frame and uses multiple sets of fasteners for fixed installation, thereby facilitating the disassembly of the sofa body frame, which is beneficial for the portable transport of the sofa body. At the same time, for sofa manufacturers, the detachable sofa facilitates the convenient logistics and delivery.

[0004] The above-mentioned technology modularizes the existing sofa frame and uses multiple sets of fasteners for fixed installation, which makes it easy to disassemble the sofa frame. However, the connection between the various parts of the sofa is not tight enough, which makes the overall structural strength of the sofa low. Therefore, this utility model discloses a disassembled sofa that can reduce storage and transportation space to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a modular sofa that can reduce storage and transportation space, thereby solving the technical problem mentioned in the background art that the connections between the various parts of a traditional modular sofa are not tight enough, resulting in low overall structural strength of the sofa.

[0006] To achieve the above objectives, the present invention provides the following solution to the aforementioned technical problems:

[0007] A modular sofa that reduces storage and transportation space includes a base frame, a sofa back, sofa leg supports, sofa armrests, sofa cushions, a cross bracket, connecting boxes, foot brackets, and recessed frames. The sofa back, sofa leg supports, and two sofa armrests are all screwed to the inner sides of the connecting boxes. The sofa cushions are screwed to the lower side of four recessed frames. The upper part of the base frame is fitted with a cross bracket, and the four sides of the cross bracket are respectively inserted into the four recessed frames. The four free ends of the cross bracket are inserted into the adjacent connecting boxes. Foot brackets are inserted at the four bottom corners of the base frame.

[0008] As a further embodiment of this utility model, baffles are fixed on the four free end faces of the cross bracket, and slots adapted to the baffles are opened on the lower side of the connecting box, and a connecting groove for accommodating the side of the cross bracket is opened on one side of the slot.

[0009] As a further embodiment of this utility model, upper notches are provided on the lower sidewalls of the four free ends of the cross bracket, and lower notches corresponding to the upper notches are provided in the middle of the four sides of the base frame.

[0010] As a further embodiment of this utility model, a rectangular groove is provided on the upper side of each of the foot steels, and a groove with the same width as the side of the base frame is provided on the upper side of each of the two adjacent sides of the rectangular groove.

[0011] As a further embodiment of this utility model, a positioning plate is fixed on one side of the connecting box, and positioning holes are provided at the four corners of the positioning plate.

[0012] As a further embodiment of this utility model, countersunk grooves are provided at both ends of the concave frame.

[0013] As a further embodiment of this utility model, the four sides of the sofa cushion are in contact with the sofa backrest, sofa leg rest and two sofa armrests respectively.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model discloses a detachable sofa that can reduce storage and transportation space. The sofa back, sofa leg support, and two sofa armrests are suspended from the four ends of a cross-shaped support through connecting boxes. The sofa cushion is limited to the upper part of the cross-shaped support by a concave frame. This structure allows the cross-shaped support to transfer the force of each part to the leg steel through the base frame, which fully ensures the structural stability of the sofa. Moreover, each part of the sofa can be disassembled, and the volume of the disassembled parts is much smaller than that of the assembled sofa, which greatly reduces storage and transportation space. This can reduce transportation costs, storage fees, and maintenance costs for warehousing.

[0016] In terms of repair and replacement, since each component is independently detachable, when a component is damaged, it is not necessary to replace the entire sofa; only the damaged component needs to be replaced. For example, if the sofa cushions are worn, they can be directly removed and replaced. The replacement process only takes 5-10 minutes, making the operation simple and convenient, greatly reducing maintenance costs and time, and bringing great convenience to users.

[0026] Please see Figure 1-6This utility model provides a detachable sofa that can reduce storage and transportation space, including a base frame 1, a sofa back 2, a sofa leg support 3, a sofa armrest 4, a sofa cushion 5, a cross bracket 6, a connecting box 7, a foot steel 8, and a concave frame 9. The four sides of the sofa cushion 5 are respectively pressed and contacted with the sofa back 2, the sofa leg support 3, and the two sofa armrests 4.

[0027] Specifically, the four sides of the sofa cushion 5 are in close contact with the sofa backrest 2, sofa leg support 3 and two sofa armrests 4 respectively, and the various parts are tightly connected to avoid looseness or gaps, so that the overall structure of the sofa is more stable and beautiful.

[0028] Furthermore, the inner sides of the sofa backrest 2, sofa leg support 3 and two sofa armrests 4 are all screwed with connecting boxes 7, and a positioning plate 73 is fixed on one side of the connecting box 7. Positioning holes 74 are opened at the four corners of the positioning plate 73.

[0029] Specifically, by using a drill gun to drill screws through positioning holes 74 into the wooden structure of the sofa backrest 2, sofa leg support 3, or sofa armrest 4, the positioning plate 73 can be connected to the sofa backrest 2, sofa leg support 3, or sofa armrest 4 into an integrated structure.

[0030] Furthermore, the sofa cushion 5 is screwed with four recessed frames 9 on the lower side, and the base frame 1 is provided with foot steel 8 at the bottom four corners. The upper side of the foot steel 8 is provided with a rectangular groove 81, and the upper side of the two adjacent sides of the rectangular groove 81 is provided with a groove 82 with the same width as the side of the base frame 1.

[0031] Specifically, the groove 82 provides an embedding space for the bottom of the base frame 1, and the rectangular groove 81 serves to connect the two embedding spaces. During installation, it can be positioned quickly and accurately, reducing installation errors. This embedded structure can effectively distribute and transfer the weight of the sofa, avoiding structural damage due to excessive local stress. In addition, the bottom of the foot steel 8 is densely covered with anti-slip protrusions, which can prevent the sofa from shifting.

[0032] Furthermore, a cross bracket 6 is inserted into the upper part of the base frame 1, and the four sides of the cross bracket 6 are respectively inserted into four recessed frames 9;

[0033] Specifically, the cross bracket 6 is similar to a "+" shaped structure with four sides, each side corresponding to the front, back, left, and right directions, while the four concave frames 9 correspond to the side in one direction.

[0034] Furthermore, upper notches 62 are provided on the lower side walls of the four free ends of the cross bracket 6, and lower notches 11 corresponding to the upper notches 62 are provided in the middle of the four sides of the base frame 1.

[0035] Specifically, the cooperation between the upper notch 62 and the lower notch 11 ensures that the cross bracket 6 can be quickly and accurately positioned in the correct position of the base frame 1 during installation. Through the interlocking structure, the weight and force of the sofa can be more evenly distributed to the base frame 1 and the leg steel 8, avoiding structural damage caused by excessive local stress, thereby extending the service life of the sofa.

[0036] Furthermore, countersunk grooves 91 are provided at both ends of the concave frame 9;

[0037] Specifically, by using a drill bit to drill the screw through the countersunk groove 91 into the wooden structure of the sofa cushion 5, the recessed frame 9 and the sofa cushion 5 can be connected as a whole. The countersunk groove 91 is used to hide the head of the screw, so that the inner wall of the recessed frame 9 can fully contact the cross bracket 6.

[0038] Furthermore, the four free ends of the cross bracket 6 are all inserted into the adjacent connecting box 7. A baffle 61 is fixed on the end face of the four free ends of the cross bracket 6. A slot 71 adapted to the baffle 61 is opened on the lower side of the connecting box 7, and a connecting groove 72 for accommodating the side of the cross bracket 6 is opened on one side of the slot 71.

[0039] Specifically, the cooperation between the baffle 61 and the slot 71 ensures the accuracy of the installation position of the connecting box 7, and the connecting groove 72 serves to accommodate the side of the cross bracket 6, enabling the cross bracket 6 to transmit the force of the connecting box 7, thereby improving the load-bearing capacity of the overall sofa structure and enhancing the stability of the structure.

[0040] Working principle: Assembly includes the following steps:

[0041] Step 1: Insert the foot steel 8 into the four corners of the base frame 1;

[0042] Step 2: Place the cross bracket 6 above the base frame 1 so that the upper notch 62 and the lower notch 11 are inserted into each other.

[0043] Step 3: Connect the slot 71 of the connecting box 7 to the baffle 61 from top to bottom, so that the sofa back 2 and the sofa leg support 3 are located on the front and back sides of the base frame 1 respectively, and the two sofa armrests 4 are located on the left and right sides of the base frame 1 respectively.

[0044] Step 4: Place the sofa cushion 5 on top of the cross bracket 6, and align and insert the four concave frames 9 with the four sides of the cross bracket 6 respectively. The sofa cushion 5 fully compresses the sofa backrest 2, sofa leg support 3 and two sofa armrests 4, which can avoid assembly seams and make the sofa more beautiful and have a stronger overall appearance.
