Description

Technical Field

[0001] This utility model belongs to the field of modular sofa technology, specifically a modular sofa that prevents gaps between sofas. Background Technology

[0002] In traditional sofa use, especially multi-unit sofas, gaps often appear. As people use sofas, due to daily sitting, lying down, moving, and the sofa's own structure, gaps gradually appear between the various components. These gaps not only affect the overall aesthetics of the sofa, significantly diminishing the decorative effect of living rooms and other spaces, but also cause inconvenience to users. For example, small items may fall into the gaps and be difficult to retrieve; pets may use the gaps as hiding places and are difficult to drive away; at the same time, the gaps easily accumulate dust and debris, making cleaning very difficult, and long-term accumulation can breed bacteria, affecting indoor environmental hygiene and human health.

[0003] Meanwhile, the patent specification with application number CN208550630U discloses a modular sofa that prevents gaps between sofa bodies. It "includes multiple sofa bodies and a tray for securing the sofa bodies together. All sofa bodies are installed in the tray. Storage cabinets for storing items are provided on both sides of the sofa bodies, and the storage cabinets are embedded within the sofa bodies. Each sofa body is provided with a plush cushion. The upper end of the plush cushion is connected to the upper end of the backrest of the sofa body via a zipper, and the lower end of the plush cushion is connected to the bottom of the backrest of the sofa body via a first Velcro fastener. This utility model, by setting up the tray, prevents the sofa bodies from separating, thus preventing children from falling into the gaps between the sofa bodies while playing on the sofa, causing safety accidents."

[0004] Existing modular sofas often feature simple connecting structures, typically using ordinary splicing methods. This leads to gaps easily forming between the sofa modules during daily use due to people sitting, lying down, moving, or external impacts. This not only affects aesthetics but can also cause items to fall into the gaps and become difficult to retrieve. Furthermore, existing sofas lack effective padding and cushioning to address these tiny gaps, allowing dust to accumulate easily and affecting the sofa's hygiene and lifespan.

[0005] Therefore, a modular sofa design is proposed to address the above-mentioned problems and prevent the formation of gaps between sofas. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a modular sofa that prevents the formation of gaps between sofas. It effectively resists external interference during daily use, fundamentally prevents the formation of gaps, ensures the overall aesthetics and practicality of the sofa, and has the advantages of preventing some dust from entering the gaps, keeping the inside of the sofa clean, and extending the service life of the sofa.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a modular sofa designed to prevent gaps between sofa sections, comprising a sofa body. Four support rods are fixedly connected to the bottom of the sofa body, and each of the four support rods has a shock-absorbing pad at its bottom. Both ends of the sofa body share a locking mechanism. The locking mechanism includes two circular grooves (first groove) on the inner surface of the sofa body. Insert rods are movably inserted into the inner surfaces of both circular grooves (first groove). Two circular grooves (second groove) are formed on the inner surfaces of both circular grooves (second groove). Each insert rod is wound with a locking spring on the inner surface of one of the two circular grooves (second groove). Lifting plates are fixedly connected to the bottom ends of both locking springs. The two lifting plates are slidably connected to the two circular grooves (second groove) and fixedly sleeved with the two insert rods. Two locking slots are formed at one end of the sofa body. Two locking blocks that engage with the locking slots are fixedly connected to the other side of the sofa body via bolts. Each locking block has a slot at one end that engages with the insert rod.

[0008] Preferably, one end of each of the two insertion rods and the two locking blocks is curved.

[0009] Preferably, the top of the sofa body has two receiving slots, and the inner surface of each of the two receiving slots is provided with a handle, and the two handles are respectively fixedly connected to two plug rods.

[0010] Preferably, two limiting blocks are fixedly connected to the outer surfaces of the two lifting plates, and the inner surfaces of the two circular grooves are provided with limiting grooves that cooperate with the two limiting blocks.

[0011] Preferably, a cushion is attached to the top of the sofa body via Velcro.

[0012] Preferably, both ends of the sofa body are fixedly connected with filling pads, and both filling pads are made of memory foam.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a snap-fit ​​mechanism, allows the plug to be automatically and tightly inserted into the slot under the action of the snap-fit ​​spring, achieving a stable connection between the two sofa bodies. This greatly enhances the connection strength between the sofa modules, effectively resists external interference during daily use, fundamentally prevents the formation of gaps between the sofas, and ensures the overall aesthetics and practicality of the sofa.

[0015] 2. The filling cotton provided at both ends of the sofa body in this utility model can fit tightly between the modules when the two sofa bodies are spliced ​​together, effectively filling potential tiny gaps and further preventing the appearance of gaps. In addition, the filling cotton has a certain dustproof function, which can block some dust from entering the gaps, keep the inside of the sofa clean, and extend the service life of the sofa.

[0024] 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.

[0025] like Figures 1 to 5 As shown, this utility model provides a modular sofa that prevents gaps between sofas, including a sofa body 1. Four support rods 7 are fixedly connected to the bottom of the sofa body 1. Each of the four support rods 7 has a shock-absorbing pad at its bottom. Both ends of the sofa body 1 are provided with a snap-fit ​​mechanism 6.

[0026] The locking mechanism 6 includes two circular grooves 69 formed on the inner surface of the sofa body 1. Insert rods 63 are movably inserted into the inner surfaces of both circular grooves 69. A second circular groove 67 is formed on the inner surface of each of the two circular grooves 69. Locking springs 61 are wound around the inner surfaces of the two insert rods 63, respectively. Lifting plates 62 are fixedly connected to the bottom ends of the two locking springs 61. The two lifting plates 62 are slidably connected to the two circular grooves 67, respectively, and are fixedly sleeved with the two insert rods 63. One end of the sofa body 1 is opened... There are two snap-fit ​​slots 65. On the other side of the sofa body 1, there are two snap-fit ​​blocks 4 that are used in conjunction with the snap-fit ​​slots 65. One end of each snap-fit ​​block 4 is provided with a slot 5 for use with the insertion rod 63. Under the action of the snap-fit ​​spring 61, the insertion rod 63 can be automatically and tightly inserted into the slot 5, so as to realize the stable connection between the two sofa bodies 1. This device greatly enhances the connection strength between the sofa modules, effectively resists external interference in daily use, fundamentally prevents the generation of gaps in the sofa, and ensures the overall aesthetics and practicality of the sofa.

[0027] Specifically, one end of each of the two insertion rods 63 and the two snap-fit ​​blocks 4 is curved. The curved design makes it easier to align and insert the insertion rods 63 and snap-fit ​​blocks 4 during assembly, which facilitates the assembly operation.

[0028] like Figures 1 to 5 As shown, the top of the sofa body 1 has two receiving slots 70, and the inner surface of each of the two receiving slots 70 is provided with a handle 68. The two handles 68 are fixedly connected to two plug rods 63 respectively. The handles 68 make it easy for the user to manually operate the plug rods 63 to raise and lower, thus improving the convenience of operation.

[0029] Furthermore, two limiting blocks 64 are fixedly connected to the outer surfaces of the two lifting plates 62, and the inner surfaces of the two circular grooves 67 are provided with limiting grooves 66 that cooperate with the two limiting blocks 64. The limiting blocks 64 cooperate with the limiting grooves 66 to prevent the lifting plates 62 from rotating unnecessarily in the circular grooves 67, thus ensuring the stability of the lifting of the rod 63.

[0030] like Figures 1 to 5 As shown, a cushion 2 is attached to the top of the sofa body 1 via Velcro. The Velcro connection makes it easy to remove and install the cushion 2, and facilitates cleaning or replacement of the cushion 2.

[0031] It is worth noting that both ends of the sofa body 1 are fixedly connected with filling pads 3. Both filling pads 3 are made of memory foam, which can effectively fill potential tiny gaps and further prevent gaps from appearing.

[0032] Working principle and process: When it is necessary to assemble sofa body 1, pull handle 68. Handle 68 drives the insertion rod 63 to rise in the first circular groove 69, overcoming the elastic force of the snap-fit ​​spring 61. The lifting plate 62 rises in the second circular groove 67. The limiting block 64 slides in the limiting groove 66 to limit the movement. Bring the sofa body 1 with snap-fit ​​block 4 close to another sofa body 1, so that snap-fit ​​block 4 is aligned with snap-fit ​​groove 65 and inserted. After it is in place, release handle 68. The snap-fit ​​spring 61 returns to its original position, causing the lifting plate 62 and insertion rod 63 to descend. Insert rod 63 is inserted into slot 5, realizing a stable snap-fit ​​between the two sofa bodies 1. At the same time, with the help of filling pad 3, gaps between sofa bodies 1 can be effectively prevented.
