DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] A spliced ​​multi-person sofa comprises at least two sofa bodies 1, wherein the sofa body 1 is a basic unit constituting the multi-person sofa and can be used as a single-person sofa. Support legs 2 are fixedly arranged at the lower end of the sofa body 1. The number of the support legs 2 is four and they are evenly distributed at the four top corners of the lower end of the sofa body 1. The sofa body 1 is supported by the support legs 2 so that there is a certain gap between the lower end of the sofa body 1 and the ground.

[0027] The lower end of the sofa body 1 is provided with an insertion box 3 and an insertion board 4, which are respectively arranged at the left and right sides of the sofa body 1 and correspond to each other. The insertion box 3 does not exceed the side setting of the sofa body 1, and the entire insertion box 3 is located in the lower end projection of the sofa body 1. The insertion board 4 extends out of the side of the sofa body 1, a part of the insertion board 4 is connected to the lower end of the sofa body 1, and the other part of the insertion board 4 extends out of the projection of the lower end of the sofa body 1, so that when two sofa bodies 1 are spliced, the insertion board 4 of one sofa body 1 can be inserted into the insertion box 3 of an adjacent sofa body 1. The insertion board 4 is detachably arranged at the lower end of the sofa body 1. Since the insertion board 4 extends into the lower end of the sofa body 1, collision is avoided during transportation. Therefore, it is installed in a detachable manner, the insertion board 4 is disassembled during transportation, and the insertion board 4 is installed on the sofa body 1 when splicing the sofas. The insertion box 3 can also be detachably installed at the lower end of the sofa body 1.

[0028] The side of the plug box 3 extends inward to be provided with a plug hole 6 that matches the plug board 4. The plug hole 6 is arranged in a narrowed shape from the outside to the inside. When two adjacent sofa bodies 1 are spliced ​​together, the plug board 4 of one sofa body 1 is correspondingly inserted into the plug hole 6 of the other sofa body 1. The part of the plug board 4 inserted into the plug hole 6 matches the shape and size of the plug hole 6, so that there will be no gap and shaking after the plug board 4 is inserted into the plug hole 6.

[0029] The lower end of the plug box 3 is provided with a through hole connected to the socket 6, and a vertically movable pin 8 is provided in the through hole. The lower end of the plug plate 4 has a pin hole 9 matching the pin 8. After the plug plate 4 is inserted into the socket 6, the pin 8 is inserted into the socket 6, so that the plug plate 4 is constrained in the plug box 3, thereby connecting two adjacent sofa bodies 1, thereby preventing the two sofa bodies 1 from sliding apart during use of the multi-person sofa.

[0030] When individual sofa bodies 1 are spliced ​​into a multi-person sofa, the plug plate 4 at the lower end of one sofa body 1 is inserted into the plug hole 6 of the plug box 3 at the lower end of the adjacent sofa body 1, and the pin 8 on the plug box 3 is inserted into the pin hole 9 at the lower end of the plug plate 4 for positioning. Since the plug hole 6 is configured in a constricted shape, the plugging and unplugging are matched with the plug hole 6, and the outer end size of the plug hole 6 is much larger than the size of the end of the plug plate 4 first inserted into the plug hole 6. Therefore, after the two sofa bodies 1 are roughly aligned, the plug plate 4 can be easily inserted into the corresponding plug hole 6 by pushing the sofa body 1 without lying on the ground for observation, thereby improving the convenience of splicing. In addition, the plug box 3 and the plug plate 4 are both arranged at the lower end of the sofa body 1. Due to their low position, they are not easy to appear in the field of vision, thus forming a hidden state, which improves the convenience of splicing and makes the overall multi-person sofa more beautiful.

[0031] A preferred technical solution is that the through hole includes an upper hole 10 extending downward from the bottom of the plug-in hole 6, the bottom center of the upper hole 10 extends downward to form a lower hole 13 passing through the lower end of the plug-in box 3, the upper hole 10 and the lower hole 13 are coaxially arranged, the cross-sections of the upper hole 10 and the lower hole 13 are both circular, and the inner diameter of the upper hole 10 is larger than the inner diameter of the lower hole 13.

[0032] The upper hole 10 is matched with a slider 11 that can slide vertically, and the slider 11 can rotate horizontally in the upper hole 10. The latch 8 is vertically arranged at the upper end of the slider 11, and moves up and down driven by the slider 11. The lower hole 13 is matched with a pull rod 5 that can move vertically, and the pull rod 5 can rotate horizontally in the lower hole 13. The upper end of the pull rod 5 extends into the upper hole 10 and is fixedly connected to the bottom of the slider 11. The lower end of the slider 11 is fixed to the bottom of the upper hole 10. A spring 12 is provided between the bottom and is sleeved on the pull rod 5. A limiting slide groove 14 extending upward from the lower end of the plug box 3 is provided at the edge of the lower hole 13. A limiting slider 15 fixed to the pull rod 5 is provided in the limiting slide groove 14 for sliding matching. The distance between the upper end of the limiting slider 15 and the lower end of the plug box 3 is consistent with the distance between the upper end of the latch 8 and the bottom of the socket 6, so that after the limiting slider 15 slides downward and out of the lower end of the plug box 3, the latch 8 moves downward and out of the pin hole 9 of the plug plate 4.

[0033] In the natural state of the spring 12, the upper end of the latch 8 extends out of the upper hole 10 and is located in the insertion hole 6. When splicing, the pull rod 5 is pulled downward, and the slider 11 drives the latch 8 to move downward, so that the latch 8 is completely hidden in the upper hole 10, and the spring 12 is compressed until the limit slider 15 slides out of the lower end of the limit slide groove 14, and then the pull rod 5 is rotated to make the limit slider 15 misaligned with the limit slide groove 14, and the limit slider 15 is against the lower end of the plug box 3, so that the latch 8 will not be in the spring 12 Under the action of elastic force, it rebounds into the socket 6, and then pushes the sofa body 1, inserts the plug plate 4 of one sofa body 1 into the socket 6 of the plug box 3 of another sofa body 1. After the plug plate 4 is fully inserted, rotate the insertion rod to align the limit slider 15 with the limit slide groove 14, and the limit slider 15 can enter the limit slide groove 14 driven by the elastic force of the spring 12, so that the latch 8 rebounds upward and is inserted into the corresponding pin hole 9 under the drive of the elastic force of the spring 12, thereby connecting the plug plate 4 and the plug box 3.

[0034] Similarly, when disassembling the two sofa bodies 1, pull the pull rod 5 downward until the limiting slider 15 slides out of the limiting slide groove 14 and rotates it. After the limiting slider 15 is pressed against the lower end of the plug box 3, the latch 8 can be pulled out of the pin hole 9, so that the plug board 4 can be pulled out of the plug box 3.

[0035] According to a preferred technical solution, a fixed pull ring 16 is provided at the lower end of the pull rod 5 .

[0036] The pull ring 16 facilitates pulling the pull rod 5 downward and rotating the pull rod 5 .

[0037] According to a preferred technical solution, the end of the plug plate 4 inserted into the plug hole 6 has a slope 7 for squeezing the plug pin 8 to move downward.

[0038] When the plug board 4 is inserted into the socket 6, the inclined surface 7 at the end of the plug board 4 can press the pin 8 downward, so that the upper end of the pin 8 is pressed against the lower end of the plug board 4 and moves until the pin 8 is aligned with the pin hole 9. The pin 8 is inserted upward into the pin hole 9 under the action of the elastic force of the spring 12. In this way, there is no need to pull the pull rod 5 to hide the pin 8 in the upper hole 10 before splicing, and the pin 8 can be inserted after the plug board 4 is inserted into the socket 6, thereby improving the efficiency of splicing.

[0039] According to a preferred technical solution, the upper end of the latch 8 is configured to be rounded.

[0040] The upper end of the latch pin 8 is rounded to make it easier to match with the inclined surface 7.

[0041] According to a preferred technical solution, a rectangular hole 17 is provided at the inner end of the plug hole 6 extending inward, and a rectangular portion 18 matching the rectangular hole 17 is protruded from the end of the plug plate 4 .

[0042] After the insertion plate 4 is completely inserted into the insertion hole 6 , the rectangular portion 18 is inserted into the rectangular hole 17 .

[0043] According to a preferred technical solution, the plug plate 4 is detachably mounted on the lower end of the sofa body 1 by means of bolts, and a mounting hole 19 for the bolts to pass through is provided on the plug plate 4.
