Description

Technical Field

[0001] The utility model relates to the technical field of furniture, in particular to a connecting member for furniture, a support frame and furniture.

Background Art

[0002] The existing furniture includes a main body and a support frame for supporting the main body. The main body can be a mattress, a sofa cushion, a table board, a seat board, etc. For the convenience of transportation, the existing support frame is a detachable support frame, which usually includes a plurality of support rods and a plurality of connecting plates. The support rods form a first member, and the connecting plates form a second member. The user assembles the plurality of support rods and the plurality of connecting plates into a support frame by screws. However, in this way, the user must rely on tools to carry out the assembly, so that the installation of the support frame is very inconvenient.

Content of the Utility Model

[0003] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a connecting member for furniture, a support frame and furniture, which can complete the assembly of the first member, the compensation piece and the second member without relying on tools, so as to make the assembly of the connecting member more convenient. In addition, it can also ensure the connection reliability between the first member and the second member and prevent the two from shaking.

[0004] To solve the above technical problem, the utility model adopts the following technical scheme:

[0005] A connecting member for furniture includes a first member, a second member and a compensation piece. The first member is provided with a slot. The second member includes a plug-in part, and the plug-in part is inserted into the slot along a first direction and there is an assembly gap between the plug-in part and the slot. The compensation piece includes a connected compensation part and a limiting part. The compensation part is in interference fit with the assembly gap so that the plug-in part is fixed in the slot, and the limiting part is limited in the slot by the acting force applied by the plug-in part along the first direction.

[0006] After the connecting member in the utility model is assembled, the limiting part is restricted in the slot by the force applied by the plug-in part along the first direction, thereby preventing the limiting part from falling out of the slot, that is, preventing the compensating part connected thereto from falling out of the assembly gap, thereby ensuring the connection reliability between the plug-in part and the slot; in addition, during assembly, when the plug-in part of the second member is inserted into the slot along the first direction, since the limiting part will be subjected to the force applied by the plug-in part along the first direction, the limiting part will be driven by the plug-in part along the first direction, thereby driving the compensating part to be inserted into the slot along the first direction, that is, the assembly of the compensating sheet can be completed at the same time as the plug-in part is inserted into the slot, thereby reducing the difficulty of inserting the compensating sheet, and the entire assembly process can be completed without the aid of tools. The first component, the compensation sheet and the second component are assembled, thereby making the assembly of the connecting component more convenient. In addition, the connection reliability of the first component and the second component can be guaranteed to avoid shaking of the two. Especially when the first direction is the downward direction of gravity, the gravity applied by the main body to the second component and the gravity of the user himself acting on the second component through the main body can be used to make the compensation sheet always maintain an interference fit with the assembly gap, so as to further improve the connection reliability of the second component and the first component; finally, the material of the compensation sheet can be different from that of the first component and the second component. Since the interference is provided by the compensation part, it is only necessary to make the compensation part have a certain toughness, so that the range of material selection for the first component and the second component can be wider.

[0007] In the above-mentioned furniture connection member, the limiting part includes a limiting piece arranged between the bottom of the slot and the bottom of the plug-in part, one end of the compensation part is connected to the limiting piece, and the other end extends in the opposite direction of the first direction and extends into the assembly gap. With such a design, the compensation piece can be pre-installed in the slot or on the plug-in part, and there is no need to limit the assembly order of the compensation piece, so the assembly is convenient, and in addition, it is also convenient to replace the compensation piece separately later.

[0008] In the above-mentioned furniture connection component, the compensation sheet includes two compensation parts arranged opposite to each other, and the limiting sheet is connected between the two compensation parts. Such a design can ensure the consistency of the insertion positions of the plug-in parts at both ends of the second component, and at the same time, the compensation sheet can be half-surrounded on the outside of the plug-in part, which can not only improve the limiting effect of the plug-in part on the limiting sheet, but also enable the compensation sheet to be pre-wrapped on the outside of the plug-in part and then inserted into the slot together with the plug-in part, so as to further reduce the difficulty of assembling the connection component.

[0009] In the above-mentioned furniture connection member, the limiting piece has an unfolded natural state and a bent state, and the limiting piece is half-surrounded on the plug-in part in the bent state. Such a design is not only conducive to the processing and forming of the limiting piece in the natural state and the transportation and packaging, but also allows the limiting piece to be bent into a matching shape according to the shape of the bottom of the plug-in part during use, thereby improving the versatility of the compensation piece.

[0010] In the above-mentioned connecting member for furniture, the compensation piece further includes a crease portion, which has a natural state of being unfolded and a bent state of being bent. The limiting piece is connected to the compensation portion through the crease portion. With such a design, it is not only beneficial to the processing, forming, transportation and packaging of the limiting piece in the natural state, but also enables the crease portion to be bent into a matching shape according to the shape of the connecting corner between the bottom and the side of the insertion portion (in the case where the cross-sectional shape of the insertion portion is rectangular) during use, so as to improve the versatility of the compensation piece.

[0011] In the above-mentioned connecting member for furniture, the thickness of the crease portion is smaller than the thickness of the limiting piece and the thickness of the compensation portion. With such a design, it can not only enable users to identify the crease portion for bending the crease portion more easily, but also make the bending of the crease portion more labor-saving.

[0012] In the above-mentioned connecting member for furniture, the limiting portion includes a limiting boss protruding from one side of the compensation portion facing the insertion portion, and the insertion portion is provided with a limiting hole, and the limiting boss is inserted into the limiting hole; and / or, the limiting portion includes a limiting hole provided on the compensation portion, and the insertion portion is provided with a limiting boss inserted into the limiting hole. With such a design, the limiting boss can be pre-inserted into the limiting hole to fix the compensation piece on the insertion portion, avoiding the compensation piece from falling off during the subsequent process of inserting the insertion portion into the slot, thereby further reducing the assembly difficulty of the connecting member and also facilitating the separate replacement of the compensation piece in the later stage.

[0013] In the above-mentioned connecting member for furniture, the limiting boss and the limiting hole are in interference fit. With such a design, it can avoid the compensation piece from shaking relative to the insertion portion, thereby ensuring the accuracy of the installation position of the compensation piece.

[0014] In the above-mentioned connecting member for furniture, the insertion portion drives the compensation portion to be inserted into the slot through the limiting portion, and the interference amount between the compensation portion and the assembly gap increases as the insertion depth of the compensation portion increases. With such a design, as the insertion portion is inserted deeper into the slot, the interference amount between the compensation portion and the assembly gap can be gradually increased, that is, the cooperation between the compensation portion and the slot and the insertion portion becomes more and more compact, thereby further improving the connection reliability between the insertion portion and the slot and avoiding the connection failure between the insertion portion and the slot during use.

[0015] In the above-mentioned connecting member for furniture, one of the side walls of the slot and the side of the compensation portion facing away from the insertion portion is provided with a groove, and the other is provided with a protrusion, and the protrusion is inserted into the groove along the first direction or its reverse direction. With such a design, the cooperation between the protrusion and the groove can also play a role in positioning the insertion position of the insertion portion to ensure the accuracy of the insertion position of the insertion portion; in addition, by providing the protrusion or groove structure on the compensation portion, it can avoid processing on the insertion portion, thereby simplifying the processing technology of the second member.

[0016] In the above-mentioned connecting member for furniture, the protrusion has a first protruding surface facing away from the provided side surface, the groove has a first recessed surface that is in interference fit with the first protruding surface, and the interference amount between the first protruding surface and the first recessed surface increases as the insertion depth of the insertion portion increases. With such a design, when the first direction is the downward gravity direction, the gravity exerted by the body on the second member and the gravity exerted by the user himself on the second member through the body can be utilized to make the insertion portion insert deeper into the slot, that is, make the protrusion insert deeper into the groove, and the interference amount between the first protruding surface and the first recessed surface gradually increases, that is, the fit between the compensation portion and the insertion portion and the slot becomes tighter and tighter, thereby further improving the connection reliability between the insertion portion and the slot and avoiding the connection failure between the insertion portion and the slot during use.

[0017] In the above-mentioned connecting member for furniture, the height of the first protruding surface protruding from the provided side surface gradually decreases along the first direction, and the recessed depth of the first recessed surface gradually decreases along the first direction. With such a design, the processing difficulty of the first protruding surface and the first recessed surface can be simplified, which is beneficial to the processing and forming of the protrusion and the groove.

[0018] In the above-mentioned connecting member for furniture, the protrusion has a second protruding surface connected between the first protruding surface and the provided side surface, the groove has a second recessed surface that is in interference fit with the second protruding surface, and the interference amount between the second protruding surface and the second recessed surface increases as the insertion depth of the insertion portion increases. In this way, the fitting tightness between the protrusion and the groove can be further increased to improve the connection reliability between the compensation portion and the slot.

[0019] In the above-mentioned connecting member for furniture, the second member extends along a second direction, the first direction intersects with the second direction, the slot has an avoidance opening for avoiding the second member, and the protrusion and the groove cooperate to limit the insertion portion in the second direction. With such a design, it can prevent the insertion portion from detaching from the slot along the second direction through the avoidance opening, thereby further improving the connection reliability between the insertion portion and the slot.

[0020] In the above-mentioned connecting member for furniture, a groove is provided on the side wall of the slot, the compensation portion is inserted into the groove along the first direction, and the interference amount between the compensation portion and the assembly gap increases as the insertion depth of the compensation portion increases. With such a design, the structure of the compensation portion can be simplified to simplify the processing technology of the compensation piece.

[0021] The present utility model also provides a support frame for furniture, including a plurality of support rods. The support frame includes the connecting member according to any one of the above technical solutions, the support rods form the second member, and the plurality of support rods are connected by a plurality of first members and compensation pieces to form the support frame. With such a design, the assembly of the support frame can be made more convenient to improve the user experience.

[0022] In the above-mentioned furniture support frame, the support frame is a bed frame, and multiple first components include at least one of an L-shaped insert block, a straight-shaped insert block, a T-shaped insert block, and a cross-shaped insert block. The L-shaped insert block is provided with two slots vertically distributed; the straight-shaped insert block includes two slots distributed in a straight shape; the T-shaped insert block is provided with three slots distributed in a T shape; the cross-shaped insert block is provided with four slots distributed in a cross shape. With such a design, first components of different shapes can be configured according to the distribution of the support rods in the bed frame to meet the assembly requirements of different bed frames.

[0023] In the above-mentioned furniture support frame, the support frame further includes feet for supporting the first components. The first components are provided with insert blocks extending downward, and the tops of the feet are provided with insertion holes for the insert blocks to be inserted into.

[0024] The present utility model also provides a piece of furniture, including a main body and a support frame for supporting the main body, and the support frame is the support frame described above.

[0053] Embodiment 1

[0054] As Figures 1 to 14 shown, the connecting member for furniture in this embodiment includes a first member 100, a second member 200, and a compensating piece 300. The first member 100 is provided with a slot 110. The second member 200 includes a plugging portion 210. The plugging portion 210 is inserted into the slot 110 along a first direction Z and there is an assembly gap between the plugging portion 210 and the slot 110. The assembly gap is the gap between the side wall of the slot and the plugging portion 210. The compensating piece 300 includes a connected compensating portion 310 and a limiting portion 320. The compensating portion 310 is in interference fit with the assembly gap so that the plugging portion 210 is fixed in the slot 110. The limiting portion 320 is limited in the slot 110 by the acting force applied by the plugging portion 210 along the first direction Z.

[0055] After the connection member in the present utility model is assembled, the limiting portion 320 is restricted within the slot 110 by the acting force applied by the insertion portion 210 along the first direction Z, thereby preventing the limiting portion 320 from disengaging from the slot 110, that is, preventing the compensation portion 310 connected thereto from disengaging from the assembly gap, thereby ensuring the connection reliability between the insertion portion 210 and the slot 110; in addition, during assembly, when the insertion portion 210 of the second member 200 is inserted into the slot 110 along the first direction Z, since the limiting portion 320 will receive the acting force applied by the insertion portion 210 along the first direction Z, the limiting portion 320 will be driven by the insertion portion 210 along the first direction Z, thereby driving the compensation portion 310 to be inserted into the slot 110 along the first direction Z, that is, the assembly of the compensation piece 300 can be completed while the insertion portion 210 is inserted into the slot 110, thereby reducing the insertion difficulty of the compensation piece 300. The assembly of the first member 100, the compensation piece 300, and the second member 200 can be completed without the aid of tools, making the assembly of the connection member more convenient. In addition, it can also ensure the connection reliability between the first member 100 and the second member 200 and prevent the two from shaking. Especially when the first direction Z is the downward gravity direction, the gravity applied by the body to the second member 200 and the gravity applied by the user himself through the body to the second member 200 can be utilized to keep the compensation piece 300 in an interference fit with the assembly gap all the time, so as to further improve the connection reliability between the second member 200 and the first member 100; finally, the material of the compensation piece 300 can also be different from that of the first member 100 and the second member 200. Since the interference amount is provided by the compensation portion 310, at this time, only the compensation portion 310 needs to have a certain toughness, so the material selection range for the first member 100 and the second member 200 can be wider, that is, both the first member 100 and the second member 200 can select materials with higher hardness to increase the structural strength of the two.

[0056] Specifically, the limiting portion 320 in this embodiment includes a limiting piece 321. The slot 110 has an oppositely arranged notch and bottom. The insertion portion 210 is inserted into the slot 110 along the first direction Z through the notch, and the limiting piece 321 is arranged between the bottom of the slot and the bottom of the insertion portion 210. One end of the compensation portion 310 is connected to the limiting piece 321, and the other end extends along the reverse direction of the first direction Z and is inserted into the assembly gap. With such a design, the compensation piece 300 can be pre-mounted in the slot 110 or on the insertion portion 210 without restricting the assembly sequence of the compensation piece 300. Therefore, the assembly is convenient. In addition, it is also convenient for the subsequent replacement of the compensation piece 300 alone.

[0057] Preferably, the number of the compensation parts 310 is two. The two compensation parts 310 are oppositely arranged and located on the opposite sides of the insertion part 210. The limiting piece 321 is connected between the two compensation parts 310. With such a design, the consistency of the insertion positions of the insertion parts 210 at both ends of the second component 200 can be ensured, the inclination of the second component 200 can be avoided, and at the same time, the limiting effect of the insertion part 210 on the limiting piece 321 can be improved. In addition, the compensation piece 300 can be pre-wrapped around the outside of the insertion part 210 in a U shape and then inserted into the slot 110 together with the insertion part 210, so as to further reduce the assembly difficulty of the connecting component. It is not only convenient for assembly but also convenient for the subsequent separate replacement of the compensation piece 300.

[0058] It can be understood that in other embodiments of the present invention, the limiting piece can also be pre-installed in the slot, and then the insertion part is inserted and the compensation piece is semi-wrapped around the outside of the insertion part, and then the second component is pressed along the first direction Z to drive the compensation piece to be inserted into the slot together.

[0059] In this embodiment, the cross-section of the second component 200 is rectangular. Due to the existence of processing errors, there are differences in the bottom corner dimensions of the second components 200 of the same batch. In order to make the compensation piece 300 adapt to the second components 200 with different cross-sectional dimensions, the compensation piece 300 in this embodiment further includes a crease part 330. The crease part 330 has a natural state in which it is unfolded (as Figure 8 shown) and a bent state in which it is bent (as Figure 3 shown). The limiting piece 321 is connected to the compensation part 310 through the crease part 330. With such a design, it is not only beneficial to the processing and forming of the limiting piece 321 in the natural state and the transportation and packaging of the compensation piece 300, but also enables the crease part 330 to be bent into a matching shape according to the shape of the connection corner between the bottom and the side of the insertion part 210 during use, so as to improve the versatility of the compensation piece 300.

[0060] Preferably, in this embodiment, the compensation piece 300 is a plastic part with a certain flexibility, and a part of the side of the compensation piece 300 facing away from the insertion part 210 is cut off, so that the thickness of the crease part 330 is less than the thickness of the limiting piece 321 and the thickness of the compensation part 310. With such a design, it can not only enable users to identify the crease part 330 to facilitate the bending of the crease part 330, but also make the bending of the crease part 330 more labor-saving.

[0061] It can be understood that in other embodiments of the present invention, the compensation piece can also be a metal part with a certain flexibility.

[0062] It can be understood that in other embodiments of the present invention, the compensation piece can also be a fixed shape matching the cross-sectional shape of the insertion part.

[0063] In addition, in this embodiment, the insertion part 210 drives the compensation part 310 to insert into the slot 110 through the limiting part 320, and the interference amount between the compensation part 310 and the assembly gap increases as the insertion depth of the compensation part 310 increases. With such a design, as the insertion part 210 inserts deeper into the slot 110, the interference amount between the compensation part 310 and the assembly gap can be gradually increased, that is, the fit between the compensation part 310 and the slot 110 and the insertion part 210 becomes tighter and tighter, thereby further improving the connection reliability between the insertion part 210 and the slot 110 and avoiding the connection failure between the insertion part 210 and the slot 110 during use.

[0064] To ensure the accuracy of the insertion position of the insertion part 210, in this embodiment, a protrusion 400 is provided on one side of each compensation part 310 facing away from the insertion part 210, and grooves 500 extending from the slot opening towards the slot bottom are provided on both side walls of the slot 110. The protrusion 400 inserts into the groove 500 along the first direction Z. The protrusion 400 has a first protrusion surface 410 on the side facing away from the compensation part 310, and the groove 500 has a first concave surface 510 that is in interference fit with the first protrusion surface 410. The interference amount between the first protrusion surface 410 and the first concave surface 510 increases as the insertion depth of the insertion part 210 increases. With such a design, the cooperation between the protrusion 400 and the groove 500 can also play a role in positioning the insertion position of the insertion part 210 to ensure the accuracy of the insertion position of the insertion part 210; in addition, by providing the protrusion 400 on the compensation part 310 and the groove 500 on the side wall of the slot, machining on the insertion part 210 can be avoided, thereby simplifying the processing technology of the second component 200; in addition, when the first direction Z is the downward gravity direction, the gravity exerted by the main body on the second component 200 and the gravity exerted by the user on the second component 200 through the main body can be utilized to make the insertion part 210 insert deeper and more smoothly into the slot 110, and thus the protrusion 400 inserts deeper into the groove 500, and the interference amount between the first protrusion surface 410 and the first concave surface 510 gradually increases, that is, the fit between the compensation part 310 and the insertion part 210 and the slot 110 becomes tighter and tighter, thereby further improving the connection reliability between the insertion part 210 and the slot 110 and avoiding the connection failure between the insertion part 210 and the slot 110 during use.

[0065] In order to make the interference amount between the first convex surface 410 and the first concave surface 510 increase as the insertion depth of the insertion portion 210 increases, in this embodiment, the height of the first convex surface 410 protruding from the set side surface gradually decreases along the first direction Z, so that the distance between the two first convex surfaces 410 gradually decreases along the first direction Z, and the recess depth of the first concave surface 510 gradually decreases along the first direction Z, so that the distance between the two first concave surfaces 510 gradually decreases along the first direction Z. The minimum distance between the two first convex surfaces 410 is greater than the minimum distance between the two first concave surfaces 510, and the maximum distance between the two first convex surfaces 410 is greater than the maximum distance between the two first concave surfaces 510. With such a design, not only can the compensation portion 310 be smoothly inserted into the assembly gap, but also the processing difficulty of the first convex surface 410 and the first concave surface 510 can be simplified, which is beneficial to the processing and forming of the convex 400 and the groove 500.

[0066] In addition, the convex 400 in this embodiment further has a second convex surface 420 connected between the first convex surface 410 and the set side surface. The second convex surface 420 is provided on opposite sides of the first convex surface 410 and extends along the first direction Z. The distance between the two second convex surfaces 420 gradually decreases along the first direction Z, that is, the convex 400 is an isosceles trapezoid with a larger upper part and a smaller lower part, and the groove 500 has a second concave surface 520 that is in interference fit with the second convex surface 420. The groove 500 is an isosceles trapezoid groove with a larger upper part and a smaller lower part. The minimum distance between the two second convex surfaces 420 is greater than the minimum distance between the two second concave surfaces 520, and the maximum distance between the two second convex surfaces 420 is greater than the maximum distance between the two second concave surfaces 520. In this way, the interference amount between the second convex surface 420 and the second concave surface 520 can increase as the insertion depth of the insertion portion 210 increases, so as to further increase the fitting tightness between the convex 400 and the groove 500, and improve the connection reliability between the insertion portion 210 and the slot 110.

[0067] In addition, when the compensation piece 300 is pre-installed on the insertion portion 210, in order to ensure the accuracy of the installation position of the compensation piece 300, the limiting portion 320 in this embodiment further includes a limiting boss 322 protruding from the side of the compensation portion 310 facing the insertion portion 210. The insertion portion 210 is provided with a limiting hole 211, and the limiting boss 322 is inserted into the limiting hole 211. The limiting boss 322 is a waist-shaped boss or a round table, etc., and the corresponding limiting hole 211 is a waist-shaped hole or a round hole. With such a design, when the second member 200 and the first member 100 are assembled, the limiting boss 322 can be pre-inserted into the limiting hole 211 to fix the compensation piece 300 on the insertion portion 210, avoiding the compensation piece 300 falling off and shaking relative to the insertion portion 210 during the subsequent process of inserting the insertion portion 210 into the slot 110. Thereby, the assembly difficulty of the connecting members is further reduced, and it is also convenient for the subsequent separate replacement of the compensation piece 300.

[0068] It can be understood that in other embodiments of the present utility model, the limiting portion further includes a limiting hole provided on the compensating portion, and the inserting portion is provided with a limiting boss inserted into the limiting hole; or the limiting portion further includes a limiting hole and a limiting boss provided on the compensating portion, and the inserting portion is provided with a limiting boss in plug-in fit with the limiting hole on the compensating portion and a limiting hole in plug-in fit with the limiting boss on the compensating portion.

[0069] The limiting boss 322 in this embodiment has a root connected to the compensating portion 310 and a top extending in the direction of the inserting portion 210. The top has a clearance fit with the limiting hole 211, while the root has an interference fit with the limiting hole 211, and the interference amount between the two increases as the depth of the root inserted into the limiting hole 211 increases. In this way, after the compensating piece 300 is subjected to a pressure in the first direction Z, the compensating portion 310 will be squeezed by the side wall of the slot. The squeezing of the side wall of the slot on the compensating portion 310 will cause the compensating portion 310 to approach the inserting portion 210, thereby causing the root to continue to insert into the limiting hole 211. Thus, the limiting boss 322 can be more tightly inlaid with the limiting hole 211, thereby improving the connection reliability between the limiting boss 322 and the inserting portion 210.

[0070] The second member 200 in this embodiment is a rod-shaped structure extending in the second direction X. The second direction X intersects with the first direction Z. Preferably, the plane where the second direction X is located is perpendicular to the first direction Z. The slot 110 has an avoidance opening 112 for avoiding the second member 200, that is, the second member 200 is arranged through the avoidance opening 112. In this way, the inserting portion 210 can be limited in the second direction X and its reverse direction by the cooperation of the protrusion 400 and the groove 500. It can not only position the inserting portion 210 to ensure the accuracy of the plugging position between the inserting portion 210 and the slot 110, but also prevent the inserting portion 210 from disengaging from the slot 110 along the second direction X from the avoidance opening 112, thereby further improving the connection reliability between the inserting portion 210 and the slot 110.

[0071] It can be understood that in other embodiments of the present utility model, the compensating piece only includes a limiting piece and a compensating portion, so that the compensating piece is in an L shape. With such a design, the inserting portion can also be fixed in the slot by the interference fit of the unilateral assembly clearance between the compensating portion and the slot and the inserting portion.

[0072] It can be understood that in other embodiments of the present utility model, the compensating piece can also be fixed on the inserting portion by a plastic coating process.

[0073] It should be noted that since the connecting member in this embodiment is mainly applied to furniture, especially to the support frame of furniture, when the support frame is in use, the first direction Z is the direction of gravity. With such a design, the gravity exerted on the second member 200 by the body provided on the support frame and the gravity exerted on the second member 200 by the user himself / herself through the body can be utilized to make the insertion part 210 insert deeper into the slot 110, which also makes the interference amount between the compensation part and the assembly gap gradually increase, that is, the cooperation between the compensation part and the insertion part 210 and the slot 110 becomes more and more compact. Thereby, the connection reliability between the insertion part 210 and the slot 110 is further improved, and the connection failure between the insertion part 210 and the slot 110 during use is avoided.

[0074] The first member 100 in this embodiment is used to connect at least two second members 200, that is, at least two second members 200 can be assembled by being inserted into the same first member 100. The number of second members 200 connected by the same first member 100 can be two, three or four. According to the number and extension direction of the second members 200, the first member 100 has different shapes, such as Figure 4 and Figure 9 As shown, the first member 100 can be an L-shaped insert block, that is, the first member 100 is provided with two slots 110 distributed vertically. In this way, the end parts of the two second members 200 can be respectively inserted into the two slots 110 of the L-shaped insert block, and through the interference fit of the compensation piece 300 with the assembly gap, the two second members 200 can be distributed vertically, that is, the extension directions of the two second members 200 are perpendicular to each other; as Figure 10 As shown, the first member 100 can be a straight-shaped insert block, that is, the first member 100 is provided with two slots 110 distributed in a straight line. The end parts of the two second members 200 are respectively inserted into the two slots 110 of the straight-shaped insert block, and through the interference fit of the compensation piece 300 with the assembly gap, the two second members 200 can be distributed in a straight line, that is, the two second members 200 extend along the same straight line; as Figure 11 and 12 As shown, the first member 100 can be a T-shaped insert block, that is, the first member 100 is provided with three slots 110 distributed in a T shape. The end parts of the three second members 200 are respectively inserted into the three slots 110 of the T-shaped insert block, and through the interference fit of the compensation piece 300 with the assembly gap, the three second members 200 can be distributed in a T shape, that is, two of the second members 200 extend along the same straight line, and the extension direction of the remaining one second member 200 is perpendicular to the extension directions of the first two second members 200, and is in the same plane or in different planes with the first two second members 200; as Figure 13As shown, the first member 100 can be a cross-shaped insert block. The cross-shaped insert block is provided with four slots 110 distributed in a cross shape. The end parts of the four second members 200 are respectively inserted into the four slots 110 of the cross-shaped insert block, and are in interference fit with the assembly gap through the compensation piece 300, so that the four second members 200 can be distributed in a cross shape. With such a design, the first member 100 with different shapes can be configured according to the distribution of the second members 200 to meet the assembly requirements of different support frames.

[0075] As Figure 14 shown, this embodiment discloses a furniture support frame using the above-mentioned connecting members, which includes a plurality of support rods. The support rods form the above-mentioned second members 200. The plurality of support rods are connected by a plurality of first members 100 and a plurality of compensation pieces 300 to form the support frame. With such a design, the assembly of the support frame can be made more convenient to improve the user experience.

[0076] The support frame in this embodiment is a bed frame. The plurality of first members 100 include at least one of an L-shaped insert block, a straight-shaped insert block, a T-shaped insert block, and a cross-shaped insert block. In order to reduce the length of the support rods, the plurality of first members 100 in this embodiment include four L-shaped insert blocks, four T-shaped insert blocks, and one cross-shaped insert block. The long side and the short side of the bed frame each include two second members 200. The interior of the bed frame is provided with two intermediate long rods extending along the same straight line and two intermediate short rods perpendicular to the intermediate long rods. The intermediate long rods and the intermediate short rods both form the second members 200. The two intermediate long rods and the two intermediate short rods are connected by a cross-shaped insert block and distributed on the same plane or different planes. The two second members 200 on the long side and the corresponding one intermediate short rod are connected by a T-shaped insert block. The two second members 200 on the short side and the corresponding one intermediate long rod are connected by a T-shaped insert block. The long side and the short side are spliced by an L-shaped insert block.

[0077] It can be understood that in other embodiments of the present invention, if the long side and the short side are each independently processed and formed by a rod, at this time, a T-shaped insert block can also be used to connect the long side and the intermediate short rod, and a T-shaped insert block can be used to connect the short side and the intermediate long rod.

[0078] It can be understood that in other embodiments of the present invention, if the intermediate long rods and the intermediate short rods are omitted from the bed frame, the cross-shaped insert block and the T-shaped insert block can be omitted. At this time, the two second members on the long side and the short side can be connected by a straight-shaped insert block.

[0079] In addition, the support frame also includes a support leg 600 for supporting the first component 100. The first component 100 is provided with an independently processed plug-in block 120. The plug-in block 120 is fixed to the first component 100 by screw connection or welding. A socket for inserting the plug-in block 120 is provided on the top of the support leg 600. Such a design can facilitate the assembly of the support leg 600 and the first component 100, so as to further reduce the difficulty of assembling the support frame.

[0080] It can be understood that in other embodiments of the present invention, a plug hole is provided on the first component, and the top of the support leg is inserted into the plug hole. Such a design can also facilitate the assembly of the first component and the support leg.

[0081] Finally, this embodiment also discloses a piece of furniture, including a main body and a support frame for supporting the main body, wherein the furniture is a bed, the main body is a mattress, and the support frame is a bed frame.

[0082] It is understandable that in other embodiments of the present invention, the furniture may also be a sofa, in which case the main body is a sofa cushion and the support frame is a sofa frame; or the furniture may be a table, a chair, outdoor furniture, etc.

[0083] Embodiment 2

[0084] like Figure 15 and 16 As shown, compared with the first embodiment, the difference of this embodiment is that in this embodiment, the compensation part 310 is not provided with a limiting boss and a limiting hole, the compensation sheet 300 is U-shaped and half-wrapped on the outside of the plug-in part 210, the compensation part 310 is inserted into the groove 500 along the first direction Z, and the side of the compensation part 310 away from the plug-in part 210 is inclined along the first direction Z toward the direction close to the plug-in part 210, the compensation part 310 is an isosceles trapezoid with a larger upper part and a smaller lower part, and the structure of the groove 500 is set with reference to the first embodiment, so that the interference between the compensation part 310 and the assembly gap can be increased as the insertion depth of the compensation part 310 increases. In addition, the structure of the compensation part 310 can also be simplified to simplify the processing technology of the compensation sheet 300.

[0085] Embodiment 3

[0086] like Figure 17 and 18 As shown, compared with the second embodiment, the difference of this embodiment is that the compensation sheet 300 in this embodiment is L-shaped and half-wrapped on the outside of the plug-in portion 210, and the two compensation sheets 300 are symmetrically arranged on both sides of the plug-in portion 210. Such a design can increase the versatility of the compensation sheet 300 to adapt to first components 100 and second components 200 of different sizes.

[0087] Embodiment 4

[0088] like Figure 19As shown, compared with the second embodiment, the difference in this embodiment is that the compensation piece 300 is a straight piece. At this time, the limiting part 320 is a limiting boss protruding from the side of the compensation part 310 facing the insertion part 210. A limiting hole is provided on the insertion part, and the limiting boss 322 is inserted into the limiting hole to fix the compensation piece 300 to the insertion part 210. When the connecting member is assembled, the compensation part 310 is inserted into the groove.

[0089] Embodiment Five

[0090] As Figure 20 shown, compared with the second embodiment, the difference in this embodiment is that the cross-section of the second member 200 in this embodiment is kidney-shaped. At this time, the limiting piece 321 has a natural state of being unfolded and a bent state of being bent. When the limiting piece 321 is in the bent state, the compensation piece 300 is in a U-shaped semi-surrounding state on the insertion part 210. With such a design, it is not only beneficial to the processing and forming of the limiting piece 321 in the natural state and the transportation and packaging of the compensation piece 300, but also enables the limiting piece 321 to be bent into a matching shape according to the shape of the bottom of the insertion part 210 during use, so as to improve the versatility of the compensation piece 300.

[0091] Embodiment Six

[0092] As Figure 21 shown, compared with the first embodiment, the difference in this embodiment is that the compensation part 310 in this embodiment does not have a limiting boss and a limiting hole. The groove 500 is provided on the side of the compensation part 310 facing away from the insertion part 210, and the protrusion 400 is provided on the side wall of the slot. The protrusion 400 has a first protrusion surface 410 facing away from the side wall of the provided slot. The first protrusion surface 410 is inclined in the direction of the first direction Z towards the side wall of the provided slot, so that the distance between the two first protrusion surfaces 410 gradually decreases along the first direction Z. The groove 500 has a first concave surface 510 that is in interference fit with the first protrusion surface 410. The minimum distance between the two first concave surfaces 510 is greater than the minimum distance between the two first protrusion surfaces 410, and the maximum distance between the two first concave surfaces 510 is greater than the maximum distance between the two first protrusion surfaces 410. During assembly, the protrusion 400 is inserted into the groove 500 along the reverse direction of the first direction, and the interference amount between the first protrusion surface 410 and the first concave surface 510 can be increased as the insertion depth of the insertion part 210 increases.

[0093] As described above, the above are only the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
