Detailed implementation mode

[0033] The following combines the embodiments and the attached Figures 1 to 14 to further describe the present invention.

[0034] Embodiment 1

[0035] A connecting rod, as Figures 1 - 5 shown, includes a central skeleton and at least two side panels, the side panels are fixedly connected to the central skeleton, in this embodiment, the connecting rod is made of aluminum profile, and the side panels are distributed around the central skeleton and are an integral structure with the central skeleton. In other embodiments, it can also be other profiles with a certain structural strength. Each of the side panels is provided with a fixing groove for installing other components of furniture. The fixing groove is recessed towards the central skeleton, and the fixing groove is continuous along the length direction of the side panel, so that other components can be connected to any position on the connecting rod as needed. A sliding groove is provided at the adjacent position of two adjacent side panels, the sliding groove is a mounting groove with a slide rail, and the sliding groove is used for installing hanging parts, and the hanging parts can be installed at any position on the connecting rod through the slide rail.

[0036] The central skeleton includes a central column 5 and connecting support plates. The connecting support plates are fixedly connected to both the central column 5 and the side panels, and the connecting support plates grow outward along the surface of the central skeleton. The central column 5 is located at the central position of the connecting rod and is a hollow structure, which can further reduce its weight. In this embodiment, in order to reduce the visible width of the furniture visually and solve the cumbersome feeling brought by the high-specification columns used in previous products to ensure structural strength, a three-sided column structure is adopted, that is, there are three side panels, namely the first side panel 1, the second side panel 2, and the third side panel 3. The first side panel 1, the second side panel 2, and the third side panel 3 are evenly distributed around the central skeleton and are respectively fixedly connected to the central skeleton. The cross-section of the structure formed by the first side panel 1, the second side panel 2, and the third side panel 3 is an isosceles triangle. In order to make the structure of the connecting rod more reasonable, it is preferably an equilateral triangle formed between the three side panels, that is, the first side panel 1, the second side panel 2, and the third side panel 3 are evenly distributed around the central column 5 at 120°.

[0037] The outer sides of the first side panel 1, the second side panel 2, and the third side panel 3, that is, the side of the outer panel away from the central skeleton, are flat planes to serve as the mating surfaces with other furniture components. In order to make the connection between other components of the furniture and the connecting rod more reliable, in this embodiment, fixing grooves are respectively provided in the middle of the first side panel 1, the second side panel 2, and the third side panel 3, namely the first fixing groove 11, the second fixing groove 21, and the third fixing groove 31. The cross-section of the fixing groove is designed as a "V" shape, that is, the fixing grooves on the first side panel 1, the second side panel 2, and the third side panel 3 are all concave inward towards the center of the connecting rod. The "V"-shaped fixing grooves protrude from the bodies of the first side panel 1, the second side panel 2, and the third side panel 3 and bulge towards the central column 5. Compared with the side panels with a full-plane structure, the protruding "V" structures on other components can be connected and matched with the "V"-shaped grooves on this connecting rod, avoiding the left-right swing and deviation when other components are connected to the side panels of the connecting rod.

[0038] Furthermore, mounting holes (not shown) are provided in the "V"-shaped fixing grooves, that is, the first fixing groove 11, the second fixing groove 21, and the third fixing groove 31 are all provided with the mounting holes. Fasteners such as screws will be installed in the mounting holes of the "V"-shaped grooves, so that not only can the connection between the two become more firm, but also the integrity of the structure of the connecting piece itself can be protected to the greatest extent without damaging the strength of the connecting rod. In another embodiment, according to needs, mounting holes can also be provided on both sides of the "V"-shaped fixing grooves of the side panels to connect with other components.

[0039] There are three connecting support plates, such as Figure 3As shown, they are the first connecting support plate, the second connecting support plate, and the third connecting support plate respectively. Correspondingly, the three connecting support plates are also evenly distributed around the central column 5 at 120°. Each of the first connecting support plate, the second connecting support plate, and the third connecting support plate has a number of branch heads, and through the branch heads, the side panel is fixedly connected to the central column 5. In this embodiment, in order to obtain the optimal structural strength and process, each of the first connecting support plate, the second connecting support plate, and the third connecting support plate is provided with three branch heads, namely the main fork head 60, the first bifurcated head 61, and the second bifurcated head 62. That is, the cross-section of each connecting support plate is in a "human" shape, making the connecting rod lighter in weight and higher in structural strength. Of course, in other embodiments, it can also be designed into other shapes according to needs. The main fork head 60 is fixedly connected to the central column 5, while the first bifurcated head 61 and the second bifurcated head 62 are respectively fixedly connected to two adjacent side panels. A cavity is formed between two adjacent connecting support plates and the side panel jointly connected by the two connecting support plates. The cavity serves the purpose of clearance, reserving space for the screws installed in the "V"-shaped fixing groove to extend into. That is, when installing screws on the side panel, the screws can extend into the cavity; at the same time, the cavity is also used for inserting connecting pieces to increase the length of the connecting rod, realizing the free assembly of furniture. In this embodiment, there are three such cavities, namely the first cavity 10, the second cavity 20, and the third cavity 30.

[0040] Specifically, as Figure 1 , 3 shown, the main fork head 60 of the first connecting support plate is connected to the central column 5. At the same time, the first bifurcated head 61 of the first connecting support plate is connected to the first side panel 1, and the second bifurcated head 62 is connected to the second side panel 2; the main fork head 60 of the third connecting support plate is connected to the central column 5. At the same time, the first bifurcated head 61 of the third connecting support plate is connected to the third side panel 3, and the second bifurcated head 62 is connected to the first side panel 1; thus, a first cavity 10 is formed between the first connecting support plate, the second connecting support plate, and the first side panel 1. The main fork head 60 of the second connecting support plate is connected to the central column 5. At the same time, the first bifurcated head 61 of the second connecting support plate is connected to the second side panel 2, and the second bifurcated head 62 is connected to the third side panel 3; thus, a second cavity 20 is formed between the first connecting support plate, the second connecting support plate, and the second side panel 2, and a third cavity 30 is formed between the second connecting support plate, the third connecting support plate, and the third side panel 3.

[0041] In this embodiment, there are three sliding grooves, namely a first sliding groove 100, a second sliding groove 200, and a third sliding groove 300. The three sliding grooves are respectively located at the joints of the pairwise connections of the first side panel 1, the second side panel 2, and the third side panel 3. That is, the first sliding groove 100 is located at the joint of the first side panel 1 and the second side panel 2, the second sliding groove 200 is located at the joint of the second side panel 2 and the third side panel 3, and the third sliding groove 300 is located at the joint of the third side panel 3 and the first side panel 1. In other words, the first side panel 1, the second side panel 2, and the third side panel 3 enclose an equilateral triangular structure with openings at all three vertices in cross-section, and the three sliding grooves are correspondingly located at the three openings, as Figure 3 shown. The three sliding grooves are respectively formed by cutting off the "tip" of the triangular structure and then digging out a groove.

[0042] Among them, the first sliding groove 100 and the third sliding groove 300 are respectively located at both ends of the first side panel 1 and are symmetric about the second sliding groove 200. That is, in this embodiment, the first fixing groove 11, the central column 5, and the second sliding groove 200 are located on the same straight line, and this straight line is the symmetric center line of the cross-section of the connecting rod, as Figure 3 shown. The structures of the first sliding groove 100 and the second sliding groove 200 are the same. When the connecting rod is vertically installed, the first side panel 1 is used to connect a first cross bar extending perpendicular to the first side panel 1, and the second side panel 2 and the third side panel 3 are respectively used to connect a second cross bar and a third cross bar extending in two opposite directions. The first cross bar and the second cross bar are in the same plane.

[0043] In this embodiment, each sliding groove includes a slide rail, and each slide rail is composed of two parts and is respectively located on both sides of the opening of each sliding groove. Described from another perspective, the slide rail is formed by the two sides of the side panel, as Figure 1 shown. The first side panel 1, the second side panel 2, and the third side panel 3 are all plate-like structures, and the two side edges of the plate-like structures protrude with clamping heads for the hanging parts installed in the sliding grooves to slide on the clamping heads. As Figure 3As shown, the chucks on the two sides of the first side panel 1 are respectively the first side plate A chuck 1a and the first side plate B chuck 1b, the chucks on the two sides of the second side panel 2 are respectively the second side plate A chuck 2a and the second side plate B chuck 2b, and the chucks on the two sides of the third side panel 3 are respectively the third side plate A chuck 3a and the third side plate B chuck 3b. That is to say, the chucks on the two sides of the first side panel 1 respectively constitute one side rail of the first chute 100 and one side rail of the third chute 300, the protruding chucks on the two sides of the second side panel 2 respectively constitute the other side rail of the first chute 100 and one side rail of the second chute 200, and the chucks on the two sides of the third side panel 3 respectively constitute the other side rail of the second chute 200 and the other side rail of the third chute 300.

[0044] As Figure 3 shown, taking the straight line where the first side panel 1 is located as the X-axis and the symmetric center line of the cross-section of the connecting rod as the Y-axis, the abscissas of the first side plate A chuck 1a and the second side plate A chuck 2a on the X-axis are the same, the abscissas of the first side plate B chuck 1b and the third side plate B chuck 3b on the X-axis are the same, and the ordinates of the second side plate B chuck 2b and the third side plate A chuck 3a on the Y-axis are the same. The projections at both ends of the first side panel 1 are flush with the projections of the second side panel 2 and the third side panel 3 in the X-axis direction. Further, the chucks are all designed with arc transitions, so that the overall structure of the connecting rod is more reasonable, the external lines of the product are more concise and smooth, and it better meets the aesthetic needs of people.

[0045] The rail is provided with a sliding surface for slidingly cooperating with the hanging member. The first side plate A chuck 1a is provided with a left sliding surface 120 of the first chute, the second side plate A chuck 2a is provided with a right sliding surface 220 of the first chute, and the left sliding surface 120 of the first chute and the right sliding surface 220 of the first chute are used for direct contact and cooperation with the hanging member. The second side plate B chuck 2b is provided with a left sliding surface 230 of the second chute, the third side plate A chuck 3a is provided with a right sliding surface 320 of the second chute, and the left sliding surface 230 of the second chute and the right sliding surface 320 of the second chute are used for direct contact and cooperation with the hanging member. The third side plate B chuck 130 is provided with a left sliding surface 130 of the third chute, the first side plate B chuck 1b is provided with a right sliding surface 330 of the third chute, and the left sliding surface 130 of the third chute and the right sliding surface 330 of the third chute are used for direct contact and cooperation with the hanging member. The present invention does not limit the shape of the sliding surface, which can be a plane, an arc surface or a curved surface.

[0046] In this embodiment, the left sliding surface 120 of the first sliding groove, the right sliding surface 220 of the first sliding groove, the left sliding surface 230 of the second sliding groove, the right sliding surface 320 of the second sliding groove, the left sliding surface 130 of the third sliding groove, and the right sliding surface 330 of the third sliding groove are flat according to design requirements, and the two corresponding sliding surfaces are located in the same plane respectively. For example, the left sliding surface 120 of the first sliding groove and the B sliding surface 220 of the first sliding groove are located in the same plane. However, in other embodiments, the two corresponding sliding surfaces may not be located in the same plane, as long as it can ensure that the hanging parts can slide smoothly in the sliding grooves according to design requirements.
