DETAILED DESCRIPTION

[0032] In order to make the technical problems, technical schemes and beneficial effects of the utility model clearer and more understandable, the utility model will be further described in detail below in combination with the drawings and embodiments.

[0033] Please refer to Figures 1 to 3 It is a joint connecting piece of a folding bed provided by the embodiment, comprising a connecting piece main body 001, the connecting piece main body 001 comprising two connecting vertical plates 011 arranged side by side, and a connecting horizontal plate 012 for connecting the two connecting vertical plates 011; two first long groove 111 are arranged side by side on the connecting vertical plate 011 along the horizontal direction, and two second long grooves 112 are further arranged on the connecting vertical plate 011, the second long groove 112 comprising a horizontal long section 113 arranged horizontally and an inclined long section 114 connected with the end of the horizontal long section 113; the two horizontal long sections 113 are located between the two first long grooves 111, and the two inclined long sections 114 are located outside the two horizontal long sections 113. The inner side between the horizontal long section 113 and the inclined long section 114 forms an angle of α, and α is an obtuse angle, preferably 120-150°, and specifically, the utility model can adopt 126.4°, and in the utility model, the distance between the horizontal long section 113 and the first long groove 111 in the horizontal direction is L1, and the distance in the vertical direction is L2, wherein L1 is 25mm, and L2 is 1.5mm.

[0034] The connecting piece main body 001 is formed by stamping the first long groove 111 and the second long groove 112 through sheet metal parts and bending. The length of the connecting vertical plate 011 along the horizontal direction is greater than the length of the connecting horizontal plate 012. Therefore, the connecting horizontal plate 012 forms an avoiding position on both sides for avoiding folding. The first connecting hole 115 is arranged near the two corners below the connecting vertical plate 011.

[0035] The joint connecting piece of the embodiment is used for connecting the first folding rod 031, and the first folding rod 031 is located between the two connecting vertical plates 011. One end of the first folding rod 031 is provided with the first through hole 311 and the second through hole 312, wherein the second through hole 312 is close to the end face of the first folding rod 031 and is used for being connected with the first long groove, and the first through hole 311 is connected with the first long groove 111.

[0036] Please refer to Figures 1 to 9 The utility model also provides a folding frame of a folding bed, and adopts a joint connecting piece. The folding frame is in a rectangular shape after being unfolded, and the folding frame further comprises corner connecting pieces 002 located at four corners, first folding assemblies 003 arranged on long sides and used for connecting two corner connecting pieces 002, and second folding assemblies 004 arranged on short sides and used for connecting two corner connecting pieces 002; the first folding assemblies 003 and the second folding assemblies 004 are both provided with two groups.

[0037] The first folding assembly 003 and the second folding assembly 004 are identical in structure, each comprising a joint connecting piece in the middle position, a first folding rod 031 and a second folding rod 032 for connecting the joint connecting piece and the corner connecting piece 002, so that there is one joint connecting piece and two first folding rods 031 and two second folding rods 032 in a set of first folding assemblies 003, and the joint connecting piece moves downward when folding. The central axes of the first folding rod 031 and the second folding rod 032 are in the same plane and arranged side by side. The first folding assembly 003 and the second folding assembly 004 differ in length after unfolding, and of course, if a square folding frame is needed, the first folding assembly 003 and the second folding assembly 004 are identical in length after unfolding.

[0038] One end of the first folding rod 031 is rotationally connected with the corner connecting piece 002, and the other end is provided with a first through hole 311 and a second through hole 312 arranged side by side. The first folding assembly 003 further comprises a first fixing piece 033 and a second fixing piece 034 for mounting the first folding rod 031 to the joint connecting piece, and the first fixing piece 033 and the second fixing piece 034 are respectively arranged corresponding to the first through hole 311 and the second through hole 312. When mounting, the first fixing piece 033 passes through the first long slot 111 on one connecting vertical plate 011, then passes through the first through hole 311, and finally passes through the first long slot 111 of the other connecting vertical plate 011 and is fixed; the second fixing piece 034 passes through the second slot 112 on one connecting vertical plate 011, then passes through the second through hole 312, and finally passes through the second slot 112 of the other connecting vertical plate 011 and is fixed. The fixing method can adopt riveting, or the first fixing piece 033 and the second fixing piece 034 adopt bolts, which can be screwed with nuts after passing through.

[0039] One end of the second folding rod 032 is rotationally connected with the corner connecting piece 002, and the other end is rotationally connected with the joint connecting piece. The first folding assembly 003 further comprises a third fixing piece 035 for connecting the second folding rod 032 to the joint connecting piece. The third fixing piece 035 first passes through the first connecting hole 115 of one connecting vertical plate 011, then passes through the second folding rod 032, and finally passes through the first connecting hole 115 of the other connecting vertical plate 011 and is fixed. The fixing method is the same as that of the first fixing piece 033.

[0040] To facilitate subsequent installation and reduce overall weight, while maintaining strength, both the first folding rod 031 and the second folding rod 032 are cylindrical rods, with the outer diameter of the first folding rod 031 being larger than that of the second folding rod 032. The inner side wall of the corner connector 002 is provided with a limiting step 021 to support the second folding rod 032. A bushing 321 is fitted at the joint connection between the second folding rod 032 and the joint, or at least one gasket 322 is provided between the second folding rod 032 and the connecting vertical plate 011, wherein the bushing 321 is directly fitted onto one end of the second folding rod 032, and the number of gaskets 322 is greater than or equal to one. The first folding rod 031 is installed to the corner connector 002 via the fourth fixing member (not shown in the figure) so that the first folding rod 031 and the corner connector 002 are rotatably connected. The second connecting rod is installed to the corner connector 002 via the fifth fixing member so that the second folding rod 032 and the corner connector 002 are rotatably connected. Two parallel limiting steps 021 are provided on either side. During installation, the fifth fixing member passes between the two limiting steps 021.

[0041] When the folding frame in this embodiment is unfolded, as follows: Figure 4 As shown, the first fixing member 033 is located inside the first long strip groove 111, that is, near the center of the joint connector. The second fixing member 034 is located inside the horizontal long strip 113. When folding, the first folding rod 031 and the second folding rod 032 rotate downward relative to the corner connector 002. The two adjacent corner connectors 002 move closer to each other, the joint connector moves downward, the first fixing member 033 slides in the first long strip groove 111 and slides to the outside. The second fixing rod slides in the horizontal long strip 113 to the inclined long strip 114 and then moves along the inclined long strip 114 to the bottom. When fully folded, the first fixing member 033 is located at the outermost side of the first long strip groove 111, and the second fixing member 034 is located at the bottom of the inclined long strip 114.

[0042] In summary, the joint connector of this utility model adopts two parallel connecting vertical plates, and the folding rod after installation can be located between the two connecting vertical plates, which can improve the overall stability and firmness and extend the service life of the folding bed.
