[0002] With the improvement of people's quality of life, mid-to-high-end sofas have entered ordinary people's homes. The stability of sofa legs is one of the important factors that determine the comfort of sofas. The sofa legs of traditional sofas are generally installed independently and used in pairs. Each single-size sofa usually needs to be installed with 2 or 4 side legs, and a three-seater sofa usually needs to be installed with 1 middle leg. The sofa legs of this connection structure are complicated to assemble and have poor stability. In addition, when multiple single-size sofas are used in combination, the sofa support leg structure is single and cannot be combined as needed, making the combined sofa easily moved by the user's push, causing misalignment or gaps between two adjacent sofas, affecting normal use. Utility Model Content

[0003] In order to make up for the deficiencies of the prior art, the utility model provides a sofa leg that can be infinitely assembled into any combination. By optimizing the structure of the sofa leg and the connection between the sofa and the sofa leg, the sofa leg can be assembled as needed to achieve the combined use of multiple sofas.

[0004] The sofa legs that can be infinitely assembled in any combination are arranged at the bottom of the sofa, and include a crossbar group and supporting legs. The crossbar group includes a plurality of crossbars connected in sequence, and the adjacent crossbars are connected by connecting pieces. The bottom of the sofa is provided with a plurality of clamping pieces that are engaged with the crossbars. The plurality of crossbars are connected by the connecting pieces and the sofa is engaged with the crossbars, so that the sofa can be assembled in any combination.

[0005] Furthermore, the crossbar group is provided with at least two supporting legs.

[0006] Furthermore, the supporting legs are H-shaped frames, and the lower part of the H-shaped frame extends toward two relatively outer sides, that is, it includes symmetrically arranged supporting legs and connecting bars connecting the two supporting legs.

A mounting plate is provided on the top of the supporting legs for cooperating with the bottom of the sofa; a mounting plate is provided in the middle of the connecting bar for cooperating with the cross bar.

[0007] Furthermore, a waist-shaped hole is arranged on the mounting plate, and a mounting hole is arranged on the mounting sheet. After the fastening bolts are inserted into the mounting holes from the through holes on the crossbar, they are fastened with nuts to connect the crossbar and the supporting feet.

[0008] Furthermore, the connecting member includes a connecting rod, an upper connecting plate and a lower connecting plate, and the connecting rod is simultaneously sleeved in two adjacent cross pieces; the upper connecting plate is a W-shaped structure, which is arranged above the connection between the two adjacent cross pieces, and the middle part is connected to the cross piece and the connecting rod; the lower connecting plate is an inverted arch structure, the middle part of which is connected to the cross piece and the connecting rod, and its two ends cooperate with the two ends of the upper connecting plate to cover the connection between the two adjacent cross pieces through fasteners, and the fastening bolts are used to pass through the upper connecting plate, the cross piece, the connecting rod, and the lower connecting plate in sequence and then cooperate with the nuts to tighten them.

[0009] Furthermore, the clamping piece is a C-shaped clamping piece, which is inserted from the upper end surface of the crossbar and cooperates with the fastener to fix the sofa and the crossbar.

[0010] Furthermore, a rubber pad is provided on one end face of the middle part of the C-shaped clip that cooperates with the cross piece; the ends of the two side walls extend outward to form a flared edge, and through holes are correspondingly provided on the two side walls, which are fixed by fasteners and the waist-shaped holes corresponding to the two side walls of the cross piece.

[0011] Compared with the prior art, the utility model has the following advantages: the utility model has a simple structure and is easy to install, and can realize unlimited sofa assembly according to needs. The sofa foot is a whole composed of a crossbar group and a supporting foot. After the clamping piece is installed on the bottom of the sofa, the sofas can be installed on the crossbar one by one through the clamping piece; when assembling heterogeneous sofas, only a corresponding number of supporting feet are added between the crossbar groups (one supporting foot is installed on the bottom of the sofa) to ensure the consistency of the combined sofa; compared with the traditional sofa with a separate supporting foot for each group, the overall structure of the sofa is more stable and safe after the sofa foot of the utility model is adopted.

DETAILED DESCRIPTION

[0018] In order to enable those skilled in the art to more clearly understand the technical solution of the present application, the present invention is further described below in conjunction with the accompanying drawings.

[0019] like Figure 1-Figure 5 As shown, a sofa leg that can be infinitely assembled in any combination is arranged at the bottom of the sofa, including a crossbar group 10 and a supporting foot 20. The crossbar group 10 includes a plurality of crossbars 11 connected in sequence, and the adjacent crossbars 11 are connected by a connecting piece 30. A plurality of clamping pieces 40 are arranged at the bottom of the sofa to engage with the crossbars 11. The plurality of crossbars 11 are connected by the connecting piece 30 and the sofa is engaged with the crossbar 11 to achieve the continuous assembly of the sofa. The crossbar group 10 is equipped with at least two supporting feet 20. To ensure stability, when the sofa is assembled, it is best to ensure that a single sofa corresponds to one supporting foot 20.

[0020] Continue reading Figure 2 It can be seen that the support leg 20 is an H-shaped frame, and the lower part of the H-shaped frame extends to two opposite outer sides, that is, it includes symmetrically arranged support legs 21 and a connecting bar 22 connecting the two support legs 21. The upper part of the support leg 21 is a vertical structure, and the lower part is inclined to the opposite outer sides of the two support legs 21. A mounting plate 23 is set on the top of the support leg 21 for matching installation with the bottom of the sofa; a mounting plate 24 is set in the middle of the connecting bar 22 for matching installation with the crossbar 11. A waist-shaped hole is set on the mounting plate 23 to facilitate horizontal fine-tuning of the hole, and it is fixed with the sofa in conjunction with a hand-tightened plastic head screw; a mounting hole is set on the mounting plate 24, and the fastening bolt is inserted from the through hole on the crossbar 11 into the mounting hole and then fastened with a nut to connect the crossbar 11 and the support leg 20. In addition, the support legs 20 on both sides can be identified inside and outside by the direction of the mounting plate 24 (the mounting plate 24 is set toward one side of the sofa) to avoid reverse installation of the support legs 20.

[0021] Continue reading Figure 3It can be seen that the connecting member 30 includes a connecting rod 31, an upper connecting plate 32 and a lower connecting plate 33, and the connecting rod 31 is simultaneously sleeved in two adjacent cross pieces 11; the upper connecting plate 32 is a W-shaped structure, arranged above the connection between the two adjacent cross pieces 11, including a middle piece and a side piece, and the middle piece in the middle is connected to the cross piece 11 and the connecting rod 31; the lower connecting plate 33 is an inverted arch structure, including a bottom wall and a side wall, and the end of the side wall away from the bottom wall extends outward to form a rib, and the bottom wall in the middle is connected to the cross piece 11 and the connecting rod 31, and the ribs at both ends cooperate with the two ends of the upper connecting plate 32 through fasteners and are fixed to the sofa through hand-tightened plastic head screws. As can be seen from the figure, the upper connecting plate 32 and the lower connecting plate 33 cooperate to cover the connection between the two adjacent crosspieces 11 and the connecting rod 31 (the connecting rod 31 is sleeved inside the two adjacent crosspieces 11), and the fastening bolts are sequentially passed through the middle section of the upper connecting plate 32, the crosspiece 11, the connecting rod 31, and the bottom wall of the lower connecting plate 33 and then fastened with nuts to further ensure the firmness of the connection at the crosspiece 11. Waist-shaped holes are set on the side sections of the upper connecting plate 32 for cooperative installation, so as to fine-tune the holes horizontally.

[0022] Continue reading Figure 4 It can be seen that the clamping member 40 is a C-shaped clamping member, which is inserted from the upper end face of the crosspiece 11 and cooperates with the fastener to fix the sofa and the crosspiece 11. A rubber pad 50 is set on the end face of one side of the middle part of the C-shaped clamping member that cooperates with the crosspiece 11 to prevent the sofa from making abnormal noises during use; the ends of the two side walls extend outward to form a flared edge 41, which is more smoothly connected with the crosspiece 11 (that is, the flared structure reduces the difficulty of insertion), and the two side walls are correspondingly provided with through holes, which are fixed with the waist-shaped holes corresponding to the two side walls of the crosspiece 11 through fasteners.
