[0019] 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.
[0020] See also Figures 1 to 4 The utility model provides a technical solution: a modular assembled sofa, including a connecting module 1 and an armrest frame 6, a backrest 8 is fixedly installed on the left side of the connecting module 1, a sofa cushion 7 is set on the outer side of the connecting module 1, a fixing groove 9 is opened near the bottom position on the front side of the connecting module 1, and the vertical sections of the fixed limit block 10 and the movable limit block 12 are both L-shaped, the rear side height value of the movable limit block 12 is greater than the front side height value, and the front side height value of the fixed limit block 10 is greater than the rear side height value. The cooperation of the movable limit block 12 and the fixed limit block 10 can ensure the stability of the connection between two adjacent connecting modules 1 and avoid the activity of the connecting module 1. At the same time, after the connection, when moving, the whole can be moved synchronously. At present, some sofas also adopt a split setting, but when there is no connection, when the user moves on the sofa, due to the smooth bottom plate and small friction, some of the split parts will move, and for children, there will be safety hazards. There are no hidden dangers. A movable groove 11 is opened near the bottom position on the rear side of the connecting module 1. A fixed limit block 10 is fixedly sleeved inside the fixed groove 9. A movable slider 13 is movably sleeved on the inner cavity of the movable groove 11. A movable limit block 12 is fixedly connected to the outer side of the movable slider 13, so that the movable slider 13 inside the front connecting module 1 can move inside the movable groove 11, so that the movable slider 13 pushes the movable limit block 12 to the outside of the connecting module 1, and then the front connecting module 1 is raised a short distance. The cooperation between the movable slider 13 and the movable groove 11 can control the position of the movable limit block 12 during use. The movable limit block 12 needs to be connected to extend out, and the unused movable limit block 12 is retracted to avoid affecting the safety of the surrounding environment of the connecting module 1. The front end of the movable slider 13 extends to the left and right sides to the outside of the connecting module 1 respectively, and the height value of the movable slider 13 is the same as the height value of the rear side of the movable limit block 12.
[0021] The front and rear inner cavities of the connecting module 1 are fixedly sleeved with a support column 2, the outer side of the support column 2 is fixedly connected with a contraction spring 3, the outer side of the contraction spring 3 is fixedly connected with a support shaft 4, and the outer side of the support shaft 4 is fixedly installed with a positioning column 5. The setting of the support column 2 can support the contraction spring 3, the support shaft 4 and the positioning column 5. During use, the contraction of the support shaft 4 and the positioning column 5 can be controlled by the contraction spring 3, thereby ensuring the stability of the armrest frame 6 and avoiding the swing of the armrest frame 6, which can ensure the integrated setting of the sofa and improve the overall stability. At the same time, after the armrest frame 6 is unfolded upward, the stability of the armrest frame 6 can be effectively guaranteed. The diameter of the support shaft 4 is the same as the inner diameter of the connecting module 1 and the handrail frame 6. The inner cavity of the connecting module 1 near the outer side and the inner cavity of the handrail frame 6 are both provided with limit grooves adapted to the positioning column 5, so that the positioning column 5 drives the support shaft 4 to move outward, so that the contraction spring 3 is in a stretched state, and the support shaft 4 moves to the position supporting the connecting module 1 and the handrail frame 6, so that the positioning column 5 is completely separated from the handrail frame 6, and then the handrail frame 6 is rotated to flip the handrail frame 6 to be located above the connecting module 1, and the axis center of the handrail frame 6 and the axis center of the support shaft 4 are located on the same horizontal line, and the length value of the support shaft 4 is greater than the width value of the top end of the handrail frame 6.
[0022] In summary, when the modular assembly sofa is used, firstly, according to the expected length requirements, the connection modules 1 of appropriate number and size are selected, so that two adjacent connection modules 1 can be assembled with each other, firstly, the movable slider 13 inside the front connection module 1 is moved inside the movable groove 11, so that the movable slider 13 pushes the movable limit block 12 to the outside of the connection module 1, and then the front connection module 1 is raised a short distance, so that the front connection module 1 drives the movable limit block 12 and the movable slider 13 to move backward, so that the bottom surface of the movable limit block 12 and the top surface of the fixed limit block 10 are fitted, and the L-shaped setting of the movable limit block 12 and the fixed limit block 10 can be used to stably connect the two connection modules. 1, install multiple connection modules 1 in sequence, then control the two sides of the connection modules 1 at both ends, first pull the positioning column 5 outward, so that the positioning column 5 drives the support shaft 4 to move outward, so that the contraction spring 3 is in a stretched state, and the support shaft 4 moves to the position of supporting the connection module 1 and the armrest frame 6, so that the positioning column 5 is completely separated from the armrest frame 6, and then the armrest frame 6 is rotated to flip the armrest frame 6 to be located above the connection module 1, and then the positioning column 5 is released, and the contraction of the contraction spring 3 is used to drive the support shaft 4 and the positioning column 5 to move toward the inside of the connection module 1, and the positioning column 5 is used to support the armrest frame 6 and the connection module 1, and then, the sofa cushion 7 is respectively installed on the outside of the connection module 1 and the armrest frame 6.
