Description

Technical Field

[0001] This utility model relates to the technical field of sofa structures, and in particular to a sofa base structure. Background Technology

[0002] As an important piece of seating in home life, the comfort and durability of sofas are of great concern. The sofa base, as a key component of the supporting structure, significantly impacts the overall performance of the sofa. Currently, there are various sofa base structures on the market, among which installing a wooden board is a common method. This typically involves fitting a single piece of wood into the sofa frame to form a wooden base. However, this type of wooden base has several drawbacks in practical use: Firstly, while a one-piece wooden base provides structural stability, it hinders airflow within the sofa. When a person sits on a sofa, heat and moisture are generated in the areas where the body contacts the seat. Under normal circumstances, this heat and moisture need to dissipate through airflow to keep the body dry and comfortable. However, the wooden base obstructs airflow, causing heat and moisture to accumulate inside the sofa, leading to a stuffy feeling for the user. For example, in hot summer weather or when sitting for extended periods, people sitting on sofas with wooden bases will clearly feel stuffy discomfort in their buttocks and back, and may even experience excessive sweating.

[0003] Secondly, the installation process is challenging. The wooden planks need to be precisely measured and cut to ensure a perfect fit with the sofa frame. In practice, due to potential dimensional deviations in the sofa frame, the installation of the planks often requires on-site adjustments and sanding, increasing the difficulty and time cost. For example, installing the wooden base of a large sofa requires multiple people to work together to move the heavy planks to the appropriate position and precisely align and secure them. Even slight deviations in the plank dimensions can lead to insecure installation or affect the overall structural stability of the sofa.

[0004] Third, disassembly and repair are difficult. Since the wooden base is installed from a single piece of wood, when disassembling and repairing internal components of the sofa (such as springs and foam), the entire wooden board needs to be pried up. During the process of prying up the board, improper force may cause the board to crack, making repair inconvenient. Utility Model Content

[0005] To overcome the technical problems of poor air permeability, difficult installation, and difficult disassembly of existing sofa bases, this utility model provides a sofa base structure, including a frame, several fixing strips, several positioning strips, and several legs. The frame has a receiving cavity. The several fixing strips are arranged at intervals along the length of the receiving cavity. The first and last ends of the fixing strips are connected to the frame. The positioning strips intersect and are fixed to the fixing strips to form several intersection points. The several legs are connected and fixed to the intersection points to support the sofa body. The sofa body is installed in the receiving cavity.

[0006] Furthermore, the positioning strip has fixed holes at both ends, and the fixing strip has mounting holes. The fixed holes and the mounting holes are arranged correspondingly to form the intersection point.

[0007] Furthermore, the middle section of the positioning strip is provided with a stabilizing hole, and the stabilizing hole and the mounting hole are correspondingly provided to form the intersection point.

[0008] Furthermore, the frame has a square or rectangular structure.

[0009] Furthermore, there are two positioning strips, which are arranged in parallel and along the length of the accommodating cavity.

[0010] Furthermore, the intersection points formed by the fixing strip and the positioning strip located near the front and rear ends of the accommodating cavity near the frame are fixedly arranged by the legs; the intersection points formed by the fixing strip and the positioning strip located at the center of the accommodating cavity are fixedly arranged by the legs.

[0011] Furthermore, it also includes a support beam located in the middle of the cavity, with its two ends connected to the frame; one of the fixing strips is located on the support beam and is connected to the support beam.

[0012] Furthermore, the frame has several burrs, which are connected end to end to form the receiving cavity. The sofa body is fitted onto the receiving cavity, and the outer edge of the sofa body abuts against the inner edge of the burrs. Beneficial effects

[0013] The beneficial effects of adopting the technical solution of this utility model are as follows: Several fixing strips are connected to the frame at both ends, allowing them to be stably installed within the frame. These strips are relatively small and flexible, allowing for easy installation and removal by a single person. This solves the problem of requiring multiple people to move a heavy, single-piece wooden board to the appropriate location for installation, as was the case in previous technologies. Furthermore, the individual fixing strips exert less strain and pressure on the frame during disassembly, allowing for clearer observation of the internal structure of the base and the connections between various components. If damage is found in a particular area, such as cracks in the frame or problems with the springs, further inspection and repair can be performed directly on the corresponding fixing strip, making problem identification more precise. This arrangement improves accuracy and facilitates subsequent maintenance. The several fixed strips are spaced apart along the length of the frame's cavity, allowing for free airflow and timely removal of heat and moisture. This solves the problem of poor air circulation inside the base caused by the density of a single-piece wooden board in the prior art. Furthermore, because the fixed strips are spaced apart, several positioning strips are needed to intersect and fix them, forming intersection points. These intersection points are connected and fixed by several legs, thus connecting and fixing the intersection positions of the fixed and positioning strips. This distributes the weight of the sofa body, supported by the fixed strips on the sofa base structure, to the positioning strips, ensuring the stability of the structure.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0018] Please refer to Figures 1 to 2 A sofa base structure includes a frame 1, several fixing strips 2, several positioning strips 3, and several support legs 4. The frame 1 has a receiving cavity 11. The several fixing strips 2 are arranged at intervals along the length direction of the receiving cavity 11. The first and last ends of the fixing strips 2 are connected to the frame 1. The positioning strips 3 intersect and are fixed to the fixing strips 2 to form several intersection points 7. The several support legs 4 are connected and fixed to the intersection points 7 to support the sofa body 6. The sofa body 6 is installed in the receiving cavity 11.

[0019] In this technical solution, the two ends of several fixing strips 2 are connected to the frame 1, allowing the fixing strips 2 to be stably installed in the frame 1. The strip-shaped fixing strips 2 are relatively small and flexible, allowing for installation and disassembly by a single person, solving the problem in the prior art where multiple people were needed to move a heavy, single-piece wooden board to the appropriate location for installation. Simultaneously, the pulling and squeezing force exerted on the frame 1 during disassembly of each fixing strip 2 is relatively small. During disassembly, the internal structure of the base and the connection status of each component can be more clearly observed. If damage is found in a certain area, such as cracks in the frame or problems with the springs, further inspection and repair can be carried out directly on the corresponding fixing strip 2, making problem identification more precise. This arrangement improves accuracy and facilitates subsequent maintenance. The fixed strips 2 are spaced apart along the length of the cavity 11 of the frame 1, allowing for free airflow and timely removal of heat and moisture, thus solving the problem of poor air circulation inside the base caused by the density of a single-piece wooden board in the prior art. Furthermore, because the fixed strips 2 are spaced apart, several positioning strips 3 are needed to intersect and be fixed to the fixed strips 2, forming intersection points 7. These intersection points 7 are connected and fixed by several legs 4, thus connecting and fixing the intersection of the fixed strips 2 and the positioning strips 3. This distributes the weight of the sofa body on the sofa base structure, supported by the fixed strips 2, to the positioning strips 3, ensuring the stability of the structure.

[0020] It is worth noting that in this technical solution, the material of the fixing strip 2 can be wood or metal. Its two ends can be snapped onto the edge of the frame 1 for easy installation and disassembly. However, the material of the fixing strip 2 is not limited. The material of the positioning strip 3 is preferably metal, but wood can also be selected. It is used to support the weight of several fixing strips 2 and can better ensure the stability of the structure. However, the material of the positioning strip 3 is not limited.

[0021] It is worth noting that several support legs 4 are interspersed and fixed in the intersection point 7 to stabilize the structure. During installation, bolts 8 pass through the positioning strip 3 and the fixing strip 2 in sequence, so that the support legs 4 are fixedly installed on the intersection point 7 by bolts 8. The sofa base structure can be suspended on the ground by the support legs 4, which reduces the impact of ground moisture on the life of the sofa base structure and the objects on the sofa base structure. Preferably, the support legs 4 are installed on all four edges of the receiving cavity 11 near the frame 1; the support legs 4 are installed in the center of the receiving cavity 11, so that the structure is stable.

[0022] Specifically, the specific assembly relationship between support leg 4 and intersection point 7 is determined by... Figure 1 and Figure 2 As shown, the intersection point 7 formed by the fixing strip 2 and the positioning strip 3 located at the front and rear ends of the cavity 11 near the frame 1 is fixedly installed by the support leg 4; the intersection point 7 formed by the fixing strip 2 and the positioning strip 3 located at the center of the cavity 11 is fixedly installed by the support leg 4. The structure is stable, saves the need for the support leg 4, and the structure can be stably installed with a high stability coefficient.

[0023] The assembly relationship between the fixing strip 2 and the positioning strip 3 is as follows: Figure 1As shown, the positioning strip 3 has fixed holes at both ends, and the fixing strip 2 has mounting holes. The fixed holes and mounting holes are correspondingly arranged to form the intersection point 7. In this embodiment, the positioning strip 3 with the positioning holes is located at the front and rear ends of the cavity 11, corresponding to the mounting holes of the fixing strip 2, forming the intersection point 7, thus defining the installation space of the frame 1. The remaining fixing strips 2 are installed along this installation space, saving materials. In this embodiment, the middle section of the positioning strip 3 has a stabilizing hole. The stabilizing hole and the mounting holes are correspondingly arranged to form the intersection point 7. It is not necessary to have multiple holes corresponding to the fixing strips 2 in the positioning strip 3. Only the stabilizing hole in the middle section of the positioning strip 3 is needed. This stabilizing hole corresponds to the mounting holes of the fixing strip 2, forming the intersection point 7, so that the positioning strip 3 and the fixing strip 2 can be stably installed together to support the objects on the sofa base structure, ensuring the stability of the structure and saving costs. Preferably, in this embodiment, the positioning strip 3... There are two positioning strips 3, which are arranged in parallel. The positioning strips 3 are arranged along the length of the accommodating cavity 11, which facilitates the distribution of the weight of objects on the sofa base structure, resulting in better load-bearing capacity. At the same time, they are easy to install. With just two positioning strips 3, several fixing strips 2 can be stably installed in the frame 1, ensuring the gaps between the fixing strips 2 and ensuring the air circulation in the sofa base structure. When disassembling, only the two positioning strips 3 need to be removed, and then the corresponding fixing strips 2 need to be removed to repair the parts in the sofa base structure that need to be replaced.

[0024] It should be noted that, by Figure 1 As shown, the frame 1 is provided with a burr 12, which surrounds the cavity 11. The fixing strip 2 is snapped onto the burr 12, making installation and disassembly convenient. The sofa body 6 is matched and installed on the cavity 11. At this time, the outer edge of the sofa body 6 abuts against the inner edge of the burr 12.

[0025] Furthermore, by Figure 1 As shown, the sofa base structure also includes a support beam 5, which is located in the middle of the receiving cavity 11. The two ends of the support beam 5 are connected to the frame 1. One of the fixing strips 2 is located on the support beam 5 and is connected to it. In this embodiment, the support beam 5 is located in the middle of the receiving cavity 11 to distribute the weight of objects on the sofa base structure, ensuring structural stability. The fixing strip 2, located on the support beam 5, positions the installation distance of the other fixing strips 2, saving materials and facilitating installation.

[0026] During installation, firstly, fixing strips 2 are installed on the left and right sides of the receiving cavity 11 of frame 1. Specifically, the fixing strips 2 are snapped onto the edges of the receiving cavity 11. Then, according to the space requirements positioned by the fixing strips 2 on the left and right sides of the receiving cavity 11, the remaining fixing strips 2 are installed to meet the space requirements, evenly distributed within the space requirements, while maintaining a spaced-apart arrangement of several fixing strips 2. Then, the first and last ends of the two positioning strips 3 correspond to the fixing strips 2 on the left and right sides of the receiving cavity 11, forming an intersection point 7. First, fix the support legs 4 to the intersection points 7 on the left and right sides of the cavity 11 with bolts 8. At this time, the middle of the positioning strip 3 and the fixing strip 2 on the supporting beam 5 of the cavity 11 also form an intersection point 7. Then fix the support legs 4 to the intersection point 7 with bolts to form the sofa base structure. Finally, place the sofa base structure flat on the ground. At this time, the positioning strip 3 is facing the ground. Then, according to the size of the space at the end of the cavity 11 away from the positioning strip 3, install the sofa body 6 on it to complete the installation.

[0027] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
