Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to an integrated, assembleable sofa structure. Background Technology

[0002] As a core piece of furniture, the sofa's structural design directly impacts its adaptability to different spaces and the user experience. Existing sofas generally suffer from the following technical defects, limiting their flexibility and practicality:

[0003] Lack of assembly and splicing capabilities: Traditional sofas are mostly fixed structures that cannot be spliced ​​together to accommodate different space sizes (such as converting a small apartment to a larger one or adjusting the living room layout). Each sofa set occupies a fixed space, resulting in low space utilization. If multiple sofa sets are forcibly placed, there is no stable connection between the sets, making them prone to displacement due to collisions, affecting aesthetics and safety. Non-adjustable sofa back angle: Sofa backs are mostly fixed at an angle (such as 105°), which cannot adapt to different usage needs (such as sitting to watch TV, reclining to rest, or lying flat for a nap). Prolonged use can easily lead to back pain and low comfort. Utility Model Content

[0022] 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.

[0023] Please see Figure 1-6 This utility model provides a technical solution: an integrated assemblable sofa structure, including a sofa 1, a sofa back 25, and a mounting frame 28. Two sets of symmetrical connecting frames 2 are fixedly connected to one side of the lower part of the sofa 1 by argon arc welding. A guide rod 3 is fixedly connected inside one set of connecting frames 2 by welding. A side lug 5 is slidably connected to the outside of the guide rod 3. A threaded rod 4 is rotatably connected inside the other side of the connecting frame 2 by a deep groove ball bearing. The other side lug 5 is threadedly connected to the outside of the threaded rod 4. One end of the threaded rod 4 extends out of the connecting frame 2 and is welded with an adjusting handwheel for easy manual rotation. A sliding plate 6 is fixedly connected between the two side lugs 5 by bolts. A first tooth groove 7 is opened on the other side of the sliding plate 6. A lifting groove 8 is opened on the other side of the lower part of the sofa 1. A lifting plate 9 is slidably connected inside the lifting groove 8. A lifting rod 10 is fixedly connected to the lower part of the lifting plate 9 by welding. The lower part of the lifting rod 10 penetrates the lower wall of the sofa 1 and is fixedly connected to a first gear 11 by a key. When the first gear 11 meshes with the first tooth groove 7, it can lock the position between two adjacent sets of sofa 1 to prevent displacement after assembly.

[0024] A spring 12 is fixedly connected between the lifting plate 9 and the top inner wall of the lifting groove 8 by spot welding. Under normal conditions, the lifting plate 9 is pushed downward to provide locking preload. The spring 12 is sleeved on the outside of the lifting rod 10 to prevent the spring 12 from shifting and getting stuck.

[0025] Rotating blocks 13 are fixedly connected to the upper two sides of the sofa 1 by bolts. Sliding rods 14 are slidably connected inside the rotating blocks 13. The two sliding rods 14 face each other and are fixedly connected to the second gear 15 by welding. The rotating blocks 13 have a receiving groove 16 that matches the second gear 15 on one side. The lower part of the sofa back 25 is fixedly connected to the connecting block 26 by bolts. The connecting block 26 has second tooth grooves 27 that match the second gear 15 on both sides.

[0026] The sofa 1 has a control groove 18 inside the rear side. The other side of the sliding rod 14 is fixedly connected to a curved plate 17 by welding. The lower part of the curved plate 17 penetrates into the control groove 18 and is fixedly connected to a rack 19 by bolts. The upper and lower racks 19 are meshed with a connecting gear 20. The middle part of the connecting gear 20 is fixedly connected to a rotating shaft 21 by a key. The tail of the rotating shaft 21 penetrates into the control groove 18 and is fixedly connected to a first connecting piece 22 by welding.

[0027] The first connecting piece 22 has a first locking screw 23 internally threaded on both sides. The sofa 1 has two sets of first locking holes 24 that cooperate with the first locking screw 23. When the second gear 15 is fully inserted into the second tooth groove 27, the first connecting piece 22 is in a horizontal position and the first locking screw 23 is inserted into the first locking hole 24 to lock the connecting gear 20 and the driven components.

[0028] Inside the mounting frame 28, a rotating rod 29 is rotatably connected via a deep groove ball bearing. A support leg 30 is fixedly connected to the outside of the rotating rod 29 by welding. The support leg 30 can rotate around the rotating rod 29 into the mounting frame 28 to achieve retraction. Mounting pieces 34 are fixedly connected to both sides of the mounting frame 28 by welding for connecting the mounting frame 28 and the sofa 1.

[0029] After one end of the rotating rod 29 penetrates the mounting bracket 28, it is fixedly connected to the second connecting piece 31 by welding. The second connecting piece 31 is internally threaded with the second locking screw 32 on one side. The mounting bracket 28 has two sets of second locking holes 33 that cooperate with the second locking screw 32 on one side. The second locking holes 33 correspond to the "expanded support" and "retracted storage" positions of the support leg 30, respectively.

[0030] Working principle: When using this utility model: rotate the handwheel of the threaded rod 4 at the bottom of the first set of sofas 1, the threaded rod 4 drives the threaded connecting lug 5 to slide along the guide rod 3, the lug 5 drives the sliding plate 6 to extend towards the second set of sofas 1, and adjust the extension length of the sliding plate 6 according to the placement position of the two adjacent sets of sofas 1.

[0031] Press the first gear 11 upwards, and the lifting rod 10 drives the lifting plate 9 to stretch the spring 12, so that the first tooth groove 7 extends to the bottom of the first gear 11 of the other sofa 1; release the first gear 11, the spring 12 returns to its original position and pushes the lifting plate 9 downwards, the first gear 11 meshes with the first tooth groove 7, and locks the position of the sliding plate 6; at this time, the two sofas 1 are firmly connected and there is no risk of displacement.

[0032] Rotate the first connecting piece 22 on the back of the sofa 1, unscrew the first locking screw 23, and release the lock on the rotating shaft 21; Adjust the angle: According to the usage needs, such as semi-reclining, rotate the first connecting piece 22 clockwise, causing the rotating shaft 21 and the connecting gear 20 to rotate synchronously; The connecting gear 20 meshes with the upper and lower sets of racks 19, driving the racks 19 to slide in the opposite direction; The racks 19 drive the sliding rod 14 to slide along the rotating block 13 through the curved plate 17, and the sliding rod 14 drives the second gear 15 to move synchronously, so that the second gear 15 disengages from the second tooth groove 27; When the sofa back 25 is adjusted to the target angle, rotate the first connecting piece 22 in the opposite direction, and the second gear 15 re-inserts into the second tooth groove 27. When the second gear 15 moves to the position, the first connecting piece 22 is in the horizontal direction. Screw the first locking screw 23 into the first locking hole 24 of the corresponding angle to fix the rotating shaft 21; At this time, the second gear 15 is tightly meshed with the second tooth groove 27 of the connecting block 26, the angle of the sofa back 25 is locked, and there is no force deviation.

[0033] Rotate the second connecting piece 31 on the outer side of the mounting bracket 28, unscrew the second locking screw 32, and release the lock of the rotating rod 29; rotate the support leg 30 inward into the mounting bracket 28, and the support leg 30 rotates around the rotating rod 29 to the outside of the mounting bracket 28 to release the support leg 30; screw the second locking screw 32 into the corresponding second locking hole 33 to fix the rotating rod 29 and the support leg 30.
