Technical Field

[0001] This utility model relates to the field of sofa frame connection technology, specifically a multi-directional sofa frame connector. Background Technology

[0002] The connection of the sofa frame is a key link to ensure the stability of the sofa structure. It is usually made possible by metal fittings (such as corner brackets, screws, pins, etc.) to precisely fix the crossbeams, legs, support frames and other components of the frame to form a stable frame. Some modern sofas also use pre-embedded nuts, snap-on designs or welding processes to enhance the connection strength, ensure that the force is evenly distributed on each component and that it is not easy to loosen. This supports the sofa seat, backrest and load-bearing requirements, ensuring safety and durability. This is why sofa connectors are needed when connecting the sofa frame.

[0003] An investigation revealed that patent CN108720399B discloses a sofa armrest support, comprising a side panel, a first telescopic rod, a second telescopic rod, a connector, and a tabletop. One end of the first telescopic rod is mounted on the side panel, and one end of the second telescopic rod is perpendicular to the other end of the first telescopic rod. The other end of the second telescopic rod is connected to the tabletop via the connector, and the other end of the second telescopic rod is rotatably connected to the connector, which is hinged to the tabletop. This invention provides a sofa armrest support that allows for multi-directional adjustment in both vertical and horizontal directions, meeting the needs of different users. Furthermore, when not in use, the support can be folded and stored in the sofa armrest, effectively solving the problem of large footprint and external storage requirements in existing armrest supports, thus reducing the space occupied by the support.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 As shown, a multi-directional sofa support connector includes a fixed long block 1, an inner cylinder 2 fixedly connected to the top of the fixed long block 1, an inner spring 3 fixedly connected inside the inner cylinder 2, a locking post 4 fixedly connected to one end of the inner spring 3, and a movable long block 5 movably connected to the outer wall of the locking post 4.

[0025] A positioning bolt 6 is movably connected to one side of the movable long block 5. A clamping frame 7 is movably connected to the outer wall of the positioning bolt 6. An installation bolt 8 is movably connected to the bottom of the clamping frame 7. This allows the sofa frame connector to achieve a multi-directional connection effect, thereby improving the environmental adaptability of the sofa frame connector, expanding the scope of use of the sofa frame connector, reducing the need for multiple sofa frame connectors in the work, and also reducing the cumbersomeness of the work.

[0026] The bottom of the fixed long block 1 is fixedly connected to a base plate 9, and the length and width of the base plate 9 are both greater than the length and width of the fixed long block 1, providing stable support for the structure. The top of the base plate 9 is movably connected to a bottom bolt 10, and there are two bottom bolts 10, which facilitates the fixing of the overall position of the structure.

[0027] The outer wall of the inner cylinder 2 is movably connected to the interior of the movable long block 5. The bottom surface of the movable long block 5 is square, and the diameter of the inner cylinder 2 is smaller than the side length of the bottom surface of the movable long block 5. This allows the inner cylinder 2 to be inserted into the interior of the movable long block 5, thereby locking the movable long block 5 with other components on the inner cylinder 2 and improving the stability of the structure after installation.

[0028] The locking column 4 is movably connected to the inner cylinder 2 via the inner spring 3. The length of the inner spring 3 and the inner cylinder 2 is less than the radius of the inner cylinder 2. The position of the movable long block 5 can be fixed by the expansion and contraction of the inner cylinder 2 within the locking column 4. This makes it easier to connect other parts of the movable long block 5 with the external structure, thus improving the overall durability of the structure. One side of the clamping frame 7 is movably connected to one side of the movable long block 5 via the positioning bolt 6. The height of the clamping frame 7 is less than the height of the movable long block 5, which makes it easy to lock the clamping frame 7 and the movable long block 5 together. This allows the clamping frame 7 to be clamped and locked with other external structures, which is beneficial for the long-term use of the structure. The interior of the clamping frame 7 is movably connected to the outer wall of the mounting bolt 8. There are four clamping frames 7 and four mounting bolts 8, which can be connected to the outside in four directions, increasing the connection range of the connector and allowing the use of different numbers of clamping frames 7 under different connection requirements.

[0029] Working principle: First, fix the base plate 9 in the working position by rotating the bottom bolt 10. Rotate to remove the positioning bolt 6, remove the clamping frame 7, and leave an appropriate number of clamping frames 7. If it is necessary to adjust the clamping direction, press the locking column 4 to make the inner spring 3 retract into the inner cylinder 2. Pull the movable long block 5 upward to a suitable height and position. Then rotate the angle of the movable long block 5 so that each clamping frame 7 reaches the appropriate position. Then press the movable long block 5 downward to complete the locking with the locking column 4. Then insert the connected bracket into the inside of the clamping frame 7 and lock the bracket and clamping frame 7 with the mounting bolt 8.
