[0045] The utility model provides a kind of plug-in connection assembly and combined sofa, it is applicable to the application scene of the adjacent sofa seating body is connected, it can be combined and connected by horizontally pushing sofa seating body without lifting sofa seating body, to simplify installation process, improve safety and convenience.

[0046] The combined sofa provided in the embodiment includes at least two sofa seating bodies, wherein the at least two adjacent sofa seating bodies are detachably connected by a set of plug-in connection assemblies.

[0047] Referring to Figure 1 For the convenience of introduction, in the embodiment, the number of sofa seating bodies is two, one of which is called "first seating body 1" and the other is called "second seating body 2".

[0048] In the embodiment, the plug-in connection assembly comprises a male fastener 3 and a female fastener 4.

[0049] Referring to Figure 2 , the male fastener 3 comprises a second fixed bottom plate 301 for connecting the second seating body 2, a rotating bottom plate 302 rotationally connected with the second fixed bottom plate 301, and a horizontal plug-in rod 303 fixed to the rotating bottom plate 302, one end of the horizontal plug-in rod 303 being fixed to the rotating bottom plate 302 and the other end protruding outside the rotating bottom plate 302, and the circumferential surface of the protruding part being provided with a clamping groove 3031. Figure 3 The rotating bottom plate 302 is designed such that when connection is needed, the horizontal plug-in rod 303 is rotated to protrude outside the second seating body 2, and when transportation is needed, the horizontal plug-in rod 303 is rotated by 90° to be accommodated below the second seating body 2.

[0050] Referring to Figure 4 , the female fastener 4 comprises a first fixed bottom plate 401 for connecting the first seating body 1 and a plug-in sleeve 402 fixed to the first fixed bottom plate 401. The plug-in sleeve 402 is provided with a horizontal insertion groove 4021 for the protruding part of the horizontal plug-in rod 303 to be inserted into, and the horizontal insertion groove 4021 is provided with a clamping fastener 4023 clamped with the clamping groove 3031.

[0051] The plug-in connection assembly and the horizontal assembly and disassembly type combined sofa provided by the embodiment,

[0052] When connection of the two sofa seating bodies is needed, the user only needs to horizontally push the two sofa seating bodies together, so that the horizontal plug-in rod 303 of the male fastener 3 is inserted into the horizontal insertion groove 4021 of the female fastener 4, which greatly reduces the physical labor, especially for large or heavy sofas. It should be noted that after the plug-in is completed, the clamping fastener 4023 can clamp the clamping groove 3031 to limit the horizontal plug-in rod 303 from being pulled out of the horizontal insertion groove 4021, ensuring the stability of the connection and avoiding the situation that the male fastener 3 and the female fastener 4 are loosened during use.

[0053] When the two sofa seating bodies need to be separated, the resistance of the clamping fastener 4023 is overcome, and the two sofa seating bodies are directly pushed apart horizontally, so that the horizontal plug-in rod 303 is pulled out of the horizontal insertion groove 4021.

[0054] Since the assembly and disassembly operation is performed on the horizontal plane, the user does not need additional help or tools to lift the sofa seating body, thereby simplifying the installation process and improving safety and convenience.

[0055] In the embodiment, the circumferential surface of the plug sleeve 402 is provided with a dismounting gap 4022 which is matched with the buckle member 4023 and communicated to the horizontal slot 4021. Optionally, the dismounting gap 4022 is located on the side of the plug sleeve 402 close to the first fixed bottom plate 401, and the first fixed bottom plate 401 is provided with an avoiding slot 4011 corresponding to the position of the dismounting gap 4022 for the buckle member 4023 to pass through.

[0056] Further, the gap between the avoiding slot 4011 and the plug sleeve 402 is smaller than the size of the buckle member 4023, so as to limit the buckle member 4023 from passing through the gap between the avoiding slot 4011 and the plug sleeve 402.

[0057] Specifically, during installation, the buckle member 4023 is first buckled into the dismounting gap 4022 through the avoiding slot 4011, and then the first fixed bottom plate 401 is installed and fixed to the first sofa seating body. At this time, the dismounting gap 4022 is opposite to the first sofa seating body and is not easy to be seen, thereby ensuring the appearance integrity of the plug sleeve 402. Further, the dismounting gap 4022 is opposite to the first sofa seating body, and if the buckle member 4023 is separated from the dismounting gap 4022 due to subsequent dismounting operation, the gap between the avoiding slot 4011 and the plug sleeve 402 is small, so the buckle member 4023 is also limited in the avoiding slot 4011 and will not fall to the ground. Subsequently, the buckle member 4023 in the avoiding slot 4011 can be taken out and reinstalled by dismounting the first fixed bottom plate 401 from the first seating body 1.

[0058] In the embodiment, the number of the clamping grooves 3031 is at least two, and each clamping groove 3031 is arranged along the axial direction of the horizontal plug rod 303.

[0059] The arrangement of the plurality of clamping grooves 3031 can not only limit the buckle member 4023 in the adjacent clamping grooves 3031 even if the buckle member 4023 is loosened from one clamping groove 3031, thereby further improving the connection reliability, but also reduce the installation distance precision requirement between the male buckle member 3 and the female buckle member 4. After installation, the buckle member 4023 can be located between the first clamping groove 3031 and the last clamping groove 3031, and the installation distance precision is not required to be too high.

[0060] In the embodiment, the buckle 4023 comprises a transverse portion 4023a and an arc-shaped portion 4023b which enclose a D-shaped hole. Optionally, one end of the arc-shaped portion 4023b is fixedly connected with the transverse portion 4023a, and the other end is arranged separately from the transverse portion 4023a, so as to enclose the D-shaped hole which is elastically buckled with the horizontal insertion rod 303 with the transverse portion 4023a. The buckle 4023 has a certain deformation capacity, which is beneficial to prolong the service life of the buckle 4023 and realize multiple insertion and disassembly operations.

[0061] In summary, the plug-in connection assembly and the combined sofa provided in the embodiment have the following advantages:

[0062] ① The connection can be completed by horizontally pushing the sofa seating body, without the need to lift the seating body, which greatly simplifies the installation steps, and the user can easily install it by himself without the need of tools and professional technical personnel, simplifies the installation process, improves the safety and the convenience of operation;

[0063] ② The design of the plurality of clamping grooves 3031 enables the buckle 4023 to be immediately buckled with the adjacent clamping groove even if the buckle 4023 is loosened from one clamping groove, thereby improving the reliability of the connection and reducing the installation precision requirement;

[0064] ③ If the buckle 4023 is separated from the disassembly gap 4022, the buckle 4023 will be limited in the avoidance groove 4011 due to the design of the avoidance groove 4011, and will not fall to the ground, which is convenient for the user to find and reinstall;

[0065] ④ Prolonged service life: the buckle 4023 has a certain deformation capacity, which is beneficial to prolong the service life, realize multiple insertion and disassembly operations, and improve the durability of the product.

[0066] Finally, it should be noted that although the above embodiments have been described in the specification and drawings of the present application, the patent protection scope of the present application should not be limited. Any equivalent structure or equivalent flow replacement or modification based on the essential concept of the present application, the contents described in the specification and drawings, and the direct or indirect implementation of the technical solutions of the above embodiments in other related technical fields, are all included in the patent protection scope of the present application.
