Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a connection assembly and a simple connection structure for the bottom connecting rod of a sectional functional sofa with component function positions. Background Art

[0002] The development process of the functional sofa field has been long, and its derivative products have become increasingly rich. However, some accessories have not been updated for more than a decade. With the continuous improvement of consumers' requirements for product quality, the quality problems accumulated in the market have become increasingly serious, and these accessories are no longer able to meet the needs. Taking the bottom connecting rod with nail angle iron connector and the bottom connecting rod with groove angle iron connector as examples, many consumers have reported that the connection of functional sofas connected with such accessories is not tight enough, there are obvious or excessive gaps between the sofas, and the gaps become more obvious when moving.

[0003] Therefore, it is necessary to provide a connection assembly to replace the existing angle iron connector and avoid the problem of obvious gaps between two objects to be connected. Summary of the Utility Model

[0004] Embodiments of the utility model provide a connection assembly and a simple connection structure for the bottom connecting rod of a sectional functional sofa to solve the problems in the prior art.

[0005] Embodiments of the utility model adopt the following technical solutions: A connection assembly includes: a first connector having a first plate member and a clamping member connected to one side of the first plate member; a second connector having a second plate member, a slot is provided on the second plate member, and the clamping member is embedded in the slot so that the second connector is attached and installed on the first connector in a manner parallel to the first connector. The connection assembly is connected to each other by the first connector and the second connector in a relatively parallel and attached manner, providing a strong connection force. Especially when applied to a sectional functional sofa, it can make the two sofas be connected more tightly together, avoiding gaps and looseness.

[0006] Preferably, the clamping member includes a limiting rod and a limiting portion, the limiting portion is installed at one end of the limiting rod, and the end of the limiting rod away from the limiting portion is installed on one side of the first plate member in a direction perpendicular to the first plate member.

[0007] Preferably, the slot penetrates through the second plate member along the thickness direction of the second plate member, and one end of the slot extends to the upper end of the second plate member to form an open end, the limiting rod is embedded in the slot from the open end, and the relative position of the second plate member with respect to the first plate member in the axial direction of the limiting rod is limited by the limiting portion. This design enables the limiting rod to be easily embedded into the slot from the open end, greatly simplifying the installation process and ensuring the stability of the connection.

[0008] Preferably, the card slot is composed of a first slot and a second slot. The first slot extends obliquely downward from the open end. The second slot extends vertically downward from the lower end of the first slot and communicates with the first slot. A limiting wall is formed at the top of the second slot. This design enables the limiting rod to slide down along the inclined surface of the first slot when entering the card slot. At the same time, when the limiting rod slides into the second slot and abuts against the bottom of the second slot, the limiting wall above can effectively prevent the first connecting member or the second connecting member from being pulled along the direction of the second slot, thus preventing the two connecting members from falling off.

[0009] Preferably, a first folding portion that turns outward and is perpendicular to the first plate member is formed at the bottom of the first plate member. A second folding portion that turns outward and is perpendicular to the second plate member is formed at the bottom of the second plate member. A plurality of bolt holes are provided on both the first folding portion and the second folding portion. The first folding portion and the second folding portion facilitate the connection of the connection assembly to two other objects to be connected.

[0010] A simple connection structure for the bottom connecting rods of a sectional functional sofa includes a connection assembly and the bottom connecting rods of at least two groups of sofa modules. The bottom connecting rods between different sofa modules are assembled through at least one group of the connection assemblies.

[0011] Preferably, when the two bottom connecting rods are assembled through one group of the connection assemblies, the first connecting member is installed on one of the bottom connecting rods, and the second connecting member is installed on the other bottom connecting rod. The two bottom connecting rods are assembled by fitting the first connecting member and the second connecting member.

[0012] The above at least one technical solution adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0013] The design structure of this connecting component is simple and does not require the use of a large number of complex parts and fasteners, thus achieving material reduction and reducing production costs to a certain extent. When applied to the production of sofas or seats, the use of the connecting component can reduce the use of metal parts, lowering material costs and weight. Additionally, for sectional sofas or seats, the overall connection stability and the compact effect after assembly are key issues. The connecting component is connected to each other in a relatively parallel and fitting manner through the first connecting piece and the second connecting piece, providing strong connection force, enabling sectional functional sofas to be connected more closely together, avoiding gaps and looseness. Secondly, this connecting component is particularly suitable for the field of sofas or seats because these furniture usually need to be disassembled and assembled frequently to meet different usage requirements. The simple operation and reliable connection of the connecting component make the sectional design of sofas or seats more flexible, facilitating users to combine and adjust according to their own needs. At the same time, the stability and durability of the connecting component also enable sofas or seats to maintain good performance during long-term use, reducing the frequency of repair and replacement.

DETAILED DESCRIPTION

[0023] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0024] The technical solutions provided by various embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] Reference Figures 1 to 5 As shown, an embodiment of the present invention provides a connection assembly, which mainly includes a first connection member 1 and a second connection member 2.

[0026] The first connector 1 comprises a first plate 11 and a clamping member 12 connected to one side of the first plate 11. The first plate 11 is generally a flat plate structure and can be made of a solid material such as metal or plastic. As part of the connecting assembly, it supports and connects other components.

[0027] The second connector 2 comprises a second plate 21 with a slot 22 formed therein. The clip 12 engages within the slot 22, allowing the second connector 2 to be mounted parallel to the first connector 1. The shape and structural design of the clip 12 should match the slot 22 of the second connector 2 to ensure smooth engagement and connection. The clip 12 can be in the form of a raised block, hook, or other shape, depending on design requirements and the required stability of the connection.

[0028] For example, in some practical applications, the connecting assembly is often used in the manufacture of sofas or chairs, where the first plate 11 can be fixed to a component of the sofa, such as the frame of the seat portion. The clip 12 can be connected to the first plate 11 by welding, bolting, or integral molding.

[0029] The second connecting member 2 mainly includes a second plate member 21 and a card slot 22. The second plate member 21 can also be made of a material similar to that of the first plate member 11. The card slot 22 is provided on the second plate member 21 for receiving the engaging member 12 of the first connecting member 1. The shape and size of the card slot 22 should closely match those of the engaging member 12 to ensure the firmness and stability of the connection. The card slot 22 can be a groove, a hole, or other structures capable of accommodating the engaging member 12. For example, on another component of the sofa, such as the frame of the backrest part, the second connecting member 2 can be installed. When it is necessary to connect the backrest to the seat, the engaging member 12 of the first connecting member 1 is inserted into the card slot 22 of the second connecting member 2 to achieve the connection of the two components.

[0030] In summary, the design of this connection assembly has a simple structure and does not require the use of a large number of complex parts and fasteners, thus achieving material reduction and reducing production costs to a certain extent. When applied to the production of sofas or seats, the use of the connection assembly can reduce the use of metal parts, lower material costs and weight. At the same time, the streamlined materials also make the appearance of the sofa or seat more concise and beautiful, meeting the design trend of modern home furnishings.

[0031] In addition, for sectional sofas or seats, the overall connection stability and the compact effect after assembly are key issues. The connection assembly is connected to each other in a relatively parallel and fitting manner through the first connecting member 1 and the second connecting member 2, providing a strong connection force, enabling the sectional functional sofa to be connected more closely together and avoiding gaps and looseness.

[0032] Secondly, this connection assembly is particularly suitable for the field of sofas or seats because these furniture usually need to be disassembled and assembled frequently to meet different usage requirements. The simple operation and reliable connection of the connection assembly make the sectional design of the sofa or seat more flexible, facilitating users to combine and adjust according to their own needs. At the same time, the stability and durability of the connection assembly also enable the sofa or seat to maintain good performance during long-term use, reducing the frequency of maintenance and replacement.

[0033] In some practical applications, referring to Figures 1 to 5 As shown, the engaging member 12 includes a limiting rod 121 and a limiting portion 122. The limiting portion 122 is installed at one end of the limiting rod 121, and the end of the limiting rod 121 away from the limiting portion 122 is installed on one side of the first plate member 11 in a direction perpendicular to the first plate member 11.

[0034] Based on the connection method between the limiting rod 121 and the first plate member 11, there are at least the following multiple implementation manners. First, the limiting rod 121 is fixedly connected to the first plate member 11. Second, the limiting rod 121 is riveted to the first plate member 11. Third, at least a part of the limiting rod 121 is threadedly connected to the threaded hole 111 on the first plate member 11. Whether it is fixedly connected, riveted or partially threadedly connected to the first plate member 11, it can provide stable support for the limiting rod 121, ensuring that the limiting rod 121 will not loosen or fall off easily during use. Furthermore, when applied to the sofa field, it can prevent the gap between two sofas from increasing when pulled (the main reason for the increase in the gap is that the strength of the connecting member is insufficient or the connection method is unstable). At the same time, the multiple connection methods provide more choices for production and installation. According to different production processes and requirements, the most suitable connection method can be selected.

[0035] Based on the above structural design of the clamping member 12, the card slot 22 penetrates through the second plate member 21 along the thickness direction of the second plate member 21, and one end of the card slot 22 extends to the upper end portion of the second plate member 21 to form an open end 221. The limiting rod 121 is inserted into the card slot 22 from the open end 221, and the second plate member 21 is axially limited relative to the first plate member 11 by the limiting portion 122 (specifically, the distance from the limiting portion 122 to the first plate member 11 is adapted to the thickness of the second plate member 21 to achieve the limit between the second plate member 21 and the first plate member 11). This design enables the limiting rod 121 to be easily inserted into the card slot 22 from the open end 221 (it can also be said to be hooked into the card slot 22), greatly simplifying the installation process. For example, when assembling a sofa or a seat, workers can quickly insert the limiting rod 121 into the card slot 22 without complex alignment and installation operations, improving the installation efficiency.

[0036] The axial limit of the second plate member 21 relative to the first plate member 11 is achieved through the limiting portion 122, ensuring the stability of the connection. During use, the second plate member 21 will not displace in the axial direction of the limiting rod 121, ensuring the overall structural stability of the sofa or seat.

[0037] Therefore, the design of the card slot 22 and the limiting rod 121 is compact and does not occupy too much space. When applied to the connection of sectional sofas or seats, it can greatly reduce the gap after assembly, making the appearance of the sofa or seat more concise and beautiful. At the same time, it is also beneficial to improve the space utilization rate of the sofa or seat, making the product more practical.

[0038] In some practical applications, refer to Figures 1 to 5As shown, on the basis of the above-mentioned card slot 22 and the engaging member 12, the structure of the card slot 22 is further optimized. Specifically, the card slot 22 is composed of a first slot 222 and a second slot 223. The first slot 222 extends obliquely downward from the open end 221, and the second slot 223 extends vertically downward from the lower end of the first slot 222 and communicates with the first slot 222. A limiting wall 224 is formed at the top of the second slot 223. This design enables the limiting rod 121 to still slide down along the inclined surface of the first slot 222 when it enters the card slot 22. At the same time, when the limiting rod 121 slides into the second slot 223 and abuts against the bottom of the second slot 223, the limiting wall 224 above it can effectively prevent the first connecting member 1 or the second connecting member 2 from being subjected to a tensile force along the direction of the second slot 223, resulting in the separation of the two connecting members. Especially when applied to the field of sectional sofas, because customers or people who do not understand the sofa structure may lift the sofa to clean or pick up something during daily use of the sofa, the setting of the limiting wall 224 can prevent the disengagement and separation of the connection assembly between the two sofas and is not easily damaged.

[0039] In practical applications, the limiting rod 121 is configured as a cylinder, and the diameter of the limiting rod 121 is adapted to the width of the second slot 223 to prevent the first connecting member 1 and the second connecting member 2 from shaking horizontally.

[0040] In some other practical applications, referring to Figures 1 to 5 As shown, a first folding corner 112 that turns outward and is perpendicular to the first plate member 11 is formed at the bottom of the first plate member 11, and a second folding corner 211 that turns outward and is perpendicular to the second plate member 21 is formed at the bottom of the second plate member 21. A plurality of bolt holes are provided on both the first folding corner 112 and the second folding corner 211. The design of the first folding corner 112 and the second folding corner 211 is mainly to facilitate the connection of the connection assembly to two other objects to be connected. The connection assembly is fixedly installed on one object to be connected by passing bolts / screws through the bolt holes on the first folding corner 112. Similarly, it is fixedly installed on the other object to be connected by passing bolts / screws through the bolt holes on the second folding corner 211. Subsequently, by connecting the first plate member 11 and the second plate member 21, the assembly or installation between the two objects to be connected can be achieved.

[0041] A simple connection structure for the bottom connecting rod of a sectional functional sofa uses the above-mentioned connection assembly and includes the bottom connecting rods 3 of at least two groups of sofa modules. The bottom connecting rods 3 between different sofa modules are assembled by at least one group of the connection assemblies (such as Figures 6 to 7 ).

[0042] Specifically, when the two bottom connecting rods 3 are assembled through a set of the connecting components, the first connecting piece 1 is installed on one of the bottom connecting rods 3, and the second connecting piece 2 is installed on the other bottom connecting rod 3. Through the fitting installation of the first connecting piece 1 and the second connecting piece 2, the assembly of the two bottom connecting rods 3 is achieved. Thus, the gap between the two assembled sofa modules can be greatly reduced. As Figure 6 and Figure 7 shown, the first connecting piece and the second connecting piece are respectively installed and fixed on the corresponding bottom connecting rods through the first folding part and the second folding part. By connecting the first connecting piece and the second connecting piece, the two sub-piece sofa modules can be tightly installed together.

[0043] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to obtain equivalent embodiments with equivalent changes, but as long as the technical content of the present invention is not departed from, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
