Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of furniture, and in particular, to a connection structure of furniture. Background Art
[0002] Some furniture, such as bed frames and storage racks, have slender structural parts. In order to reduce the packaging volume, these structural parts are usually transported in an unassembled state. During the installation process, it is usually necessary to assemble the various structural parts with the help of fasteners, such as screws. However, this connection method has the problem of complex assembly operations, and additional tools are required when disassembling and assembling furniture. Utility Model Content
[0003] In view of this, the present disclosure provides a connection structure, aiming to improve the efficiency of assembly and disassembly.
[0004] The connection structure provided by the present disclosure includes a first structural member, a connection seat, and a second structural member. The first structural member extends in the up-down direction, and the connection seat is arranged on one side of the first structural member in the first direction and fixed to the first structural member, and the first direction is substantially perpendicular to the up-down direction. The second structural member extends in the first direction and includes a connection portion. One of the connection seat and the connection portion is provided with a convex strip and the other is provided with a narrow slot, so that as the connection portion moves downward toward the connection seat, the narrow slot receives the convex strip to connect the connection portion with the connection seat.
[0005] According to this structure, during the assembly process, the two structural members can be assembled together by only moving the connecting portion downward toward the connecting seat so that the narrow groove receives the convex strip. This assembly method is easy to operate and does not rely on additional tools.
[0006] In a possible implementation, both the convex strip and the narrow groove are inclined relative to the up-down direction.
[0007] The ridges and the slots are inclined relative to the up and down directions, that is, the ridges and the slots form an angle with the length direction of the second structural member, which helps to decompose the force and reduce the force acting on the connection position of the ridges and the slots, so that the connection between the connecting part and the connecting seat is not easy to loosen, especially when facing up and down swinging centered on the connecting structure.
[0008] In a possible implementation, both the convex strip and the narrow groove are inclined downward toward the first structural member.
[0009] Both the convex strip and the narrow groove are inclined downward as they approach the first structural member, so when the connecting portion is connected to the connecting seat, the connecting portion needs to approach the first structural member and be inserted downward. In this way, as the connecting portion approaches the first structural member and is inserted downward, on the one hand, the narrow groove and the convex strip gradually fit together, and on the other hand, the gap between the connecting portion and the outer surface of the first structural member gradually becomes smaller. When the convex strip is completely inserted into the narrow groove, the end face of the second structural member contacts the outer surface of the first structural member, so that the outer surface of the first structural member and the convex strip or the narrow groove can form a clamping force on the connecting portion, thereby improving the stability of the connecting structure.
[0010] In a possible implementation, the convex strip and the narrow groove both form an angle of 75 degrees to 85 degrees with the first direction.
[0011] Research has found that the convex strips and narrow grooves with this feature can more effectively prevent the connecting seat and the connecting part from loosening, further reducing the risk of the connecting seat and the connecting part falling off.
[0012] In a possible implementation, the connection seat includes an insertion portion, and a convex strip is provided on each side of the insertion portion in a second direction, and the second direction is perpendicular to the upper and lower sides and the first direction. The connection portion has a U-shaped cross-sectional shape that is open downward to allow the insertion portion to be at least partially inserted into the connection portion. Each of the two connection portion side walls of the connection portion in the second direction is provided with a narrow groove that is open downward.
[0013] During the assembly process, the cooperation between the insertion part and the connection part can help align the convex strips and the narrow slots to reduce the difficulty of assembly. In addition, the cooperation between the two connection part side walls and the insertion part can improve the ability of the connection structure to resist the swing in the width direction to further improve the connection strength. In addition, the insertion part is provided with a convex strip on each side of the second direction, and the two connection part side walls are provided with narrow slots. The cooperation of multiple convex strips and multiple narrow slots can also further improve the connection strength.
[0014] In one possible implementation, the insertion portion has an upwardly open U-shaped cross-sectional shape, each of the two insertion portion side walls in the second direction of the insertion portion is provided with a mounting groove, and the connecting seat also includes an insert inserted into the mounting groove, and the insert protrudes outward in the second direction beyond the portion of each insertion portion side wall as a convex strip.
[0015] According to this structure, during the assembly process, the plug-in piece can be connected to the connection seat by simply moving the plug-in piece downward toward the connection seat so that the installation groove receives the plug-in piece. On the other hand, the plug-in piece protrudes outward in the second direction beyond each side wall of the insertion portion, so that after the connection portion is connected to the connection seat, the inner surface of the connection portion contacts the outer surface of the insertion portion, and the convex strip is received by the narrow groove of the connection portion, which can further improve the connection strength.
[0016] In a possible implementation, the connecting seat also includes a bottom plate, which is provided with two snap-in grooves extending in the up-down direction and spaced apart in the second direction, and each side wall of the insertion part in the second direction has a snap-in portion extending in the first direction toward the first structural member, and the snap-in portion of each side wall of the insertion part is inserted into a corresponding snap-in groove, and the insertion part is fixed to the first structural member through the bottom plate.
[0017] The connecting seat can be connected to the bottom sheet as a whole by means of a snap connection and can be fixed to the first structural member through the bottom sheet.
[0018] In a possible implementation, the insertion portion has a downwardly open U-shaped cross-section, and each of the two insertion portion side walls of the insertion portion in the second direction is provided with an outwardly bent outward portion, and the outwardly bent portion serves as a convex strip.
[0019] The convex strip is formed by using a part of the side wall of the insertion part without adding additional components, which can lessen the damage to the connection seat to ensure the strength of the connection structure, and can also reduce the number of components of the connection structure, reducing manufacturing costs and processing complexity.
[0020] In one possible implementation, the insertion portion has a U-shaped cross-sectional shape, and the insertion portion includes two insertion portion side walls and an insertion portion transverse wall, the two insertion portion side walls are spaced apart in the second direction, and the insertion portion transverse wall extends between the two insertion portion side walls, and the connecting seat also includes three outer bending portions, which are respectively connected to the two insertion portion side walls and the insertion portion transverse wall, each outer bending portion is bent outward from an end of a corresponding one of the three that is closer to the first structural member in the first direction, and the insertion portion is fixed to the first structural member through the three outer bending portions.
[0021] The outer bending portion is formed by using a part of the insertion portion transverse wall and the insertion portion side wall, so that no additional components are needed when fixing the connecting seat, which can reduce the number of components of the connecting structure and reduce production costs.
[0022] In one possible implementation, the insertion portion has a U-shaped cross-sectional shape, the insertion portion includes two insertion portion side walls spaced apart in the second direction, the connecting seat also includes two inner bending portions respectively connected to the two insertion portion side walls, each inner bending portion bends inward from an end of the corresponding insertion portion side wall that is away from the first structural member in the first direction.
[0023] A portion of the side wall of the insertion portion is bent inwardly to at least partially close an end in the first direction away from the first structural member, thereby improving the structural strength of the connecting seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] The following is an exemplary description of the embodiments of the present disclosure in conjunction with the accompanying drawings. It should be understood that the present disclosure can be implemented in a variety of ways and should not be construed as being limited to the embodiments described here. The embodiments described here are only for a more thorough and clear understanding of the present disclosure.
[0037] The present disclosure provides a piece of furniture 200. For example, the piece of furniture 200 may be a bed frame. Of course, the piece of furniture 200 is not limited to a bed frame, and may also be other types of furniture, such as a storage rack. Figure 1 The furniture 200 may include a first structure member 10 and a second structure member 20 , which may be assembled together via a connection structure 100 .
[0038] refer to Figure 2 The connection structure 100 includes a first structural member 10, a connection seat 30 and a second structural member 20. The first structural member 10 extends in the up-down direction, the connection seat 30 is arranged on one side of the first structural member 10 in the first direction and is fixed to the first structural member 10, and the first direction is substantially perpendicular to the up-down direction. The second structural member 20 extends in the first direction and includes a connection portion 21, wherein the connection seat 30 is provided with a convex strip 321, and the connection portion 21 is provided with a narrow groove 211, and as the connection portion 21 moves downward toward the connection seat 30, the narrow groove 211 can receive the convex strip 321 to connect the connection portion 21 with the connection seat 30.
[0039] According to this structure, during the assembly process, the two structural members can be assembled together by simply moving the connecting portion 21 downward toward the connecting seat 30 so that the narrow groove 211 receives the convex strip 321. This assembly method is easy to operate and does not rely on additional tools.
[0040] It is understood that in the present disclosure, directional descriptions such as "upper", "lower", "inner", "outer", etc. are relative rather than absolute. These directional descriptions are applicable when the elements in the present disclosure are in the placement postures and placement positions shown in the figures, or in the placement postures and placement positions used in daily life. For example, when the furniture 200 is used in daily life, the up and down directions in this document may be parallel to the direction of gravity.
[0041] For ease of understanding, in the drawings of the present disclosure, arrow Z+ can be used to indicate the upper side of the up-down direction, and arrow Z- can be used to indicate the lower side of the up-down direction; arrow X+ and arrow X- can be used to indicate the opposite sides of a first direction orthogonal to the up-down direction; arrow Y+ and arrow Y- can be used to indicate the opposite sides of a second direction orthogonal to both the up-down direction and the first direction. The connector 30 takes the first direction as the length direction. These elements, such as the first structural member 10, the second structural member 20, and the connector 30, can all take the second direction as the width direction.
[0042] Continue to refer Figure 2 , the convex strip 321 and the narrow groove 211 are inclined relative to the up-down direction. That is, the convex strip 321 and the narrow groove 211 form an angle α with the first direction, which helps to decompose the force and reduce the force acting on the connection position of the convex strip 321 and the narrow groove 211, so that the connection between the connecting portion 21 and the connecting seat 30 is not easy to loosen.
[0043] refer to Figure 2 and Figure 3, the convex strip 321 and the narrow groove 211 are both inclined downwardly toward the first structural member 10. The convex strip 321 and the narrow groove 211 are both inclined downwardly toward the first structural member 10, so when the connecting portion 21 is connected to the connecting seat 30, the connecting portion 21 needs to be close to the first structural member 10 and inserted downwardly. In this way, as the connecting portion 21 approaches the first structural member 10 and is inserted downwardly, on the one hand, the narrow groove 211 and the convex strip 321 gradually fit together, and on the other hand, the gap between the connecting portion 21 and the outer surface of the first structural member 10 gradually becomes smaller. When the convex strip 321 is fully inserted into the narrow groove 211, the end face of the second structural member 20 contacts the outer surface of the first structural member 10, which enables the outer surface of the first structural member 10 and the convex strip 321 to form a clamping force on the connecting portion 21, thereby improving the stability of the connecting structure 100.
[0044] Continue to refer Figure 2 The convex strip 321 and the narrow groove 211 both form an angle α of 75 to 85 degrees with the first direction. Studies have found that the convex strip 321 and the narrow groove 211 with such features can more effectively prevent the connection seat 30 and the connection part 21 from loosening, and further reduce the risk of the connection seat 30 and the connection part 21 falling off.
[0045] Continue to refer Figure 3 The connection seat 30 includes an insertion portion 31, and each side of the insertion portion 31 in the second direction is provided with a convex strip 321. The connection portion 21 has a U-shaped cross-sectional shape open downward to allow the insertion portion 31 to be at least partially inserted into the connection portion 21. Each of the two connection portion side walls 212 of the connection portion 21 in the second direction is provided with a narrow groove 211 open downward.
[0046] During the assembly process, the cooperation between the insertion portion 31 and the connection portion 21 can help align the ridges 321 and the slots 211 to reduce the difficulty of assembly. In addition, the cooperation between the two connection portion side walls 212 and the insertion portion 31 can improve the ability of the connection structure 100 to resist the swing in the width direction, so as to further improve the connection strength. In addition, the insertion portion 31 is provided with ridges 321 on each side of the second direction thereof, and the two connection portion side walls 212 are provided with slots 211. The cooperation between multiple ridges 321 and multiple slots 211 can also further improve the connection strength.
[0047] It is understandable that the number of the protrusions 321 and the narrow grooves 211 can be multiple, and the present disclosure does not impose any particular limitation on this.
[0048] refer to Figure 3 and Figure 4The insertion portion 31 has an upwardly open U-shaped cross-sectional shape, and each of the two insertion portion side walls 311 of the insertion portion 31 in the second direction is provided with a mounting groove 312. The connecting seat 30 also includes an insert piece 32 inserted into the mounting groove 312, and the insert piece 32 protrudes outward in the second direction beyond the portion of each insertion portion side wall 311 as a convex strip 321.
[0049] According to this structure, during the assembly process, the inserting piece 32 can be connected to the connection seat 30 by simply moving the inserting piece 32 downward toward the connection seat 30 so that the mounting groove 312 receives the inserting piece 32. On the other hand, the inserting piece 32 protrudes outward in the second direction beyond each insertion portion side wall 311, so that after the connection portion 21 is connected to the connection seat 30, the inner surface of the connection portion 21 abuts against the outer surface of the insertion portion 31, and the convex strip 321 is received by the narrow groove 211 of the connection portion 21, which can further improve the connection strength.
[0050] It is understood that there are many ways to implement the insertion piece 32 with the convex strip 321. As an example, refer to Figure 3 and Figure 4 , on the lower side of the insert 32, the convex strip 321 and the insert 32 form a notch 3211, so that after the insert 32 is inserted into the mounting groove 312, the connecting portion of the insert 32 and the mounting groove 312 can obtain a larger contact area with the side wall 311, thereby improving the connection reliability between the insert 32 and the mounting groove 312. Of course, in other embodiments, the convex strip 321 and the insert 32 may not form a notch, that is, the insert 32 extends outward along the second direction according to the original width, and the portion beyond the outer surface of the side wall 311 is the convex strip 321.
[0051] refer to Figure 3 and Figure 4 After the insert 32 is inserted into the mounting groove 312, the top of the insert 32 is substantially flush with the top of the mounting groove 312. Thus, above the insertion portion 31, the top of the insert 32 can disperse the force from the connecting portion 21, so that the structure of the insertion portion 31 is not easily crushed.
[0052] refer to Figure 4 The connection seat 30 may further include a bottom sheet 33, the bottom sheet 33 is provided with two clamping grooves 331 extending in the up-down direction and spaced apart in the second direction, each insertion portion side wall 311 of the insertion portion 31 in the second direction has a clamping portion 313 extending in the first direction toward the first structural member 10, the clamping portion 313 of each insertion portion side wall 311 is inserted into a corresponding clamping groove 331, and the insertion portion 31 is fixed to the first structural member 10 through the bottom sheet 33. Through the clamping form, the insertion portion 31 can be connected to the bottom sheet 33 as a whole and fixed to the first structural member 10 through the bottom sheet 33.
[0053] Furthermore, combined with Figure 3 The first structural member 10 may be provided with a receiving groove 11 on one side of the fixing seat 31 in the first direction. The clamping portion 313 of the fixing seat 31 can pass through the clamping groove 331 and be received by the receiving groove 11, so that the fixing seat 31 can be reliably fixed to the first structural member 10.
[0054] It can be understood that there are many ways to fix the bottom plate 33 and the inserting portion 31 to the first structural member 10, such as welding, bonding, bolt connection, etc., and the present disclosure does not impose any particular limitation on this.
[0055] It should be understood that there are many ways to implement the connection structure 100 of the present disclosure, and it should not be construed as being limited to the above-described embodiments. Figures 5 to 8 , the modified examples of the present disclosure are illustrated. It should be noted that the aforementioned embodiment and the following modified examples have some common elements. In the following modified examples, these elements will continue to use the figure numerals in the aforementioned embodiment to omit repeated description.
[0056] refer to Figure 5 and Figure 6 In the connection structure 100a, the insertion portion 31a has a U-shaped cross-section shape that is open downward, and each of the two insertion portion side walls 311a of the insertion portion 31 in the second direction is provided with an outwardly bent outward portion, and the outwardly bent portion serves as a convex strip 321. The convex strip 321a is formed by using a part of the insertion portion side wall 311a, without adding additional components, which can less damage the connection seat 30 to ensure the strength of the connection structure 100, and can also reduce the number of components of the connection structure 100a, thereby reducing manufacturing costs and processing complexity.
[0057] Continue to refer Figure 6 and Figure 7 The insertion portion 31 has a U-shaped cross-sectional shape. The insertion portion 31 includes two insertion portion side walls 311a and an insertion portion transverse wall 312a. The two insertion portion side walls 311a are spaced apart in the second direction. The insertion portion transverse wall 312a extends between the two insertion portion side walls 311a. The connection seat 30a also includes three outer bending portions 33. The three outer bending portions 33 are respectively connected to the two insertion portion side walls 311a and the insertion portion transverse wall 312a. Each outer bending portion 33 is bent outward from an end of a corresponding one of the three that is closer to the first structural member 10a in the first direction. The insertion portion 31 is fixed to the first structural member 10a through the three outer bending portions 33. The outer bending portion 33 is formed by using a part of the insertion portion transverse wall 312a and the insertion portion side wall 311a, so that no additional components are needed when fixing the connection seat 30a, which can reduce the number of components of the connection structure 100a and reduce production costs.
[0058] As an example, the outer bending portion 33 may be fixed to the first structural member 10a by welding. Of course, in other embodiments, the outer bending portion 33 may also be fixed to the first structural member 10a in other directions, and the present disclosure does not impose any particular limitation on this.
[0059] refer to Figure 6 and Figure 8 The insertion portion 31a has a U-shaped cross-sectional shape, and the insertion portion 31a includes two insertion portion side walls 311a spaced apart in the second direction. The connecting seat 30 also includes two inner bending portions 34 respectively connected to the two insertion portion side walls 311a, and each inner bending portion 34 is bent inward from one end of the corresponding insertion portion side wall 311a that is away from the first structural member 10a in the first direction. A portion of the insertion portion side wall 311a is bent inward to at least partially close the end of the first direction that is away from the first structural member 10a. In this way, the structural strength of the connecting seat 30a can be improved.

The term "according to" means "at least in part according to". The term "one embodiment" means "at least one embodiment"; the term "another embodiment" means "at least another embodiment".
[0061] It should be understood that although the terms “first” or “second”, etc. may be used in the present disclosure to describe various elements, these elements are not defined by these terms, and these terms are only used to distinguish one element from another.
