SUMMARY

[0003] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a furniture connecting member, support frame and furniture, which can complete the assembly of the first member and the second member without the aid of tools, so that the assembly of the connecting member is more convenient, and in addition, the connection reliability of the first member and the second member can be guaranteed, and the shaking of the two can be avoided.

[0004] To solve the above technical problems, the present application adopts the following technical solutions:

[0005] A furniture connecting member includes a first member having a slot and a second member having a plug-in part, the plug-in part is inserted into the slot along a first direction, the slot has a first side surface, the plug-in part has a second side surface, the first side surface and the second side surface are interference fit; and / or, one of the slot and the plug-in part is provided with a protrusion, and the other is provided with a groove, the protrusion is inserted into the groove along the first direction or in the opposite direction of the first direction and is interference fit.

[0006] In the connecting member, when assembling, the insertion part of the second member can be inserted into the insertion slot along the first direction by applying a force to the second member in the first direction, and the first side and the second side are in interference fit, and / or the protrusion and the groove are in interference fit, so that the insertion part is prevented from shaking in the insertion slot, thereby ensuring the connection reliability of the first member and the second member, especially when the first direction is the direction of gravity, the gravity applied by the body to the second member and the gravity applied by the user to the second member through the body can make the insertion part and the insertion slot always in interference fit, thereby further improving the connection reliability of the second member and the first member. In addition, the entire assembly process does not require any tools, so that the assembly of the connecting member is more convenient. Finally, by designing the protrusion and the groove, the insertion part can be effectively limited in at least one direction other than the first direction, thereby further improving the connection reliability of the insertion part and the insertion slot.

[0007] In the connecting member, the interference amount between the first side and the second side increases with the increase of the insertion depth of the insertion part; and / or the interference amount between the protrusion and the groove increases with the increase of the insertion depth of the insertion part. In this way, as the insertion part is inserted deeper into the insertion slot, the interference amount between the insertion part and the insertion slot gradually increases, that is, the fit between the insertion part and the insertion slot becomes more and more compact, thereby further improving the connection reliability of the insertion part and the insertion slot, and avoiding the connection failure of the insertion part and the insertion slot during use.

[0008] In the connecting member, the insertion slot has two oppositely arranged first sides, the first side includes a first guide section and a first fit section connected between the first guide section and the bottom wall of the insertion slot, the first guide section is in clearance fit with the second side, and the first fit section is in interference fit with the second side, and the interference amount of the two increases with the increase of the insertion depth of the insertion part. In this way, through the guidance of the first guide section, the insertion part can be smoothly inserted into the insertion slot, thereby reducing the difficulty of inserting the insertion part into the insertion slot, that is, the insertion part is more labor-saving when initially inserted into the insertion slot, thereby making the assembly of the connecting member more simple and convenient. In addition, when the first direction is the direction of gravity, the gravity applied by the body to the second member and the gravity applied by the user to the second member through the body can make the insertion part insert deeper into the insertion slot, so that the interference amount between the insertion part and the insertion slot gradually increases, that is, the fit between the insertion part and the insertion slot becomes more and more compact, thereby further improving the connection reliability of the insertion part and the insertion slot, and avoiding the connection failure of the insertion part and the insertion slot during use.

[0009] In the connecting member for furniture, the first fitting section is arranged to be inclined inwardly along the first direction, and the maximum distance between the two first fitting sections is smaller than the distance between the two second side surfaces. In this way, the insertion of the insertion part along the first fitting section is smooth, and the insertion part is prevented from being stuck, without changing the structure of the second member, and the processing of the first fitting section is facilitated, thereby reducing the processing difficulty of the insertion slot.

[0010] In the connecting member for furniture, the first side surface is an inclined surface arranged to be inclined inwardly along the first direction. In this way, the first guiding section and the first fitting section are smoothly connected, so that the insertion part can be smoothly slid onto the first fitting section from the first guiding section, thereby reducing the insertion difficulty of the insertion part, and making the assembly more labor-saving. In addition, the processing difficulty of the first side surface is reduced, thereby reducing the processing difficulty of the insertion slot.

[0011] In the connecting member for furniture, the second side surface comprises a second fitting section and a second guiding section inserted into the insertion slot before the second fitting section, the second guiding section is in clearance fit with the first side surface, the second fitting section is in interference fit with the first side surface, and the interference amount of the two increases with the increase of the insertion depth of the insertion part. In this way, the insertion part can be smoothly inserted into the insertion slot, thereby reducing the difficulty of inserting the insertion part into the insertion slot, i.e. the insertion part is more labor-saving in the initial stage of being inserted into the insertion slot, thereby making the assembly of the connecting member more simple and convenient. In addition, when the first direction is the direction of gravity, the gravity of the body acting on the second member and the gravity of the user acting on the second member through the body can make the insertion part be inserted deeper into the insertion slot, so that the interference amount between the insertion part and the insertion slot increases gradually, i.e. the fit between the insertion part and the insertion slot is more and more compact, thereby further improving the connection reliability of the insertion part and the insertion slot, and avoiding the connection failure of the insertion part and the insertion slot during use.

[0012] In the connecting member for furniture, one of the protrusion and the recess is arranged on the first side surface, and the other is arranged on the second side surface. The protrusion has a first protruding surface facing away from the arranged side surface, and the recess has a first recessed surface in interference fit with the first protruding surface. The interference amount between the first protruding surface and the first recessed surface increases with the increase of the insertion depth of the insertion part. In this way, the user can easily observe the positions of the protrusion and the recess during assembly, so as to align the protrusion with the recess, thereby reducing the assembly difficulty of the insertion part and the insertion slot. When the first direction is the direction of gravity, the gravity of the body acting on the second member and the gravity of the user acting on the second member through the body can make the insertion part be inserted deeper into the insertion slot, so that the protrusion is inserted deeper into the recess, and the interference amount between the first protruding surface and the first recessed surface increases gradually, i.e. the fit between the insertion part and the insertion slot is more and more compact, thereby further improving the connection reliability of the insertion part and the insertion slot, and avoiding the connection failure of the insertion part and the insertion slot during use.

[0013] In the above connecting member for furniture, the protrusion has a second protrusion surface connecting between the first protrusion surface and the set side surface, the groove has a second recess surface in interference fit with the second protrusion surface, and the interference amount between the second protrusion surface and the second recess surface increases with the increase of the insertion depth of the insertion part. In this way, the fitting tightness of the protrusion and the groove is further increased with the increase of the insertion depth of the protrusion, so as to improve the connection reliability of the insertion part and the insertion groove.

[0014] In the above connecting member for furniture, the protrusion is arranged on the bottom wall of the insertion groove and extends in the opposite direction of the first direction, the groove is arranged on the insertion part, and the interference amount between the protrusion and the groove increases with the increase of the insertion depth of the insertion part. In this way, the protrusion can be hidden after the assembly of the insertion part and the insertion groove, so as to improve the appearance of the connecting member. In addition, when the first direction is the direction of gravity, the gravity of the body acting on the second member and the gravity of the user acting on the second member through the body can make the insertion part be inserted deeper into the insertion groove, so that the protrusion is inserted deeper into the groove, the interference amount between the protrusion and the groove gradually increases, that is, the fitting of the insertion part and the insertion groove is more and more compact, thereby further improving the connection reliability of the insertion part and the insertion groove, and avoiding the connection failure of the insertion part and the insertion groove during use.

[0015] In the above connecting member for furniture, the second member extends in the second direction, the first direction intersects with the second direction, the insertion groove has an avoiding opening for avoiding the second member, and the protrusion and the groove are in fit to limit the insertion part in the second direction. In this way, the insertion part can be prevented from escaping from the avoiding opening along the second direction, thereby further improving the connection reliability of the insertion part and the insertion groove.

[0016] The application further provides a support frame for furniture, which comprises a plurality of support rods, the support frame comprising the connecting member according to any one of the above technical solutions, the support rods forming the second member, and the plurality of support rods being connected to form the support frame through the plurality of first members. In this way, the assembly of the support frame is more convenient, so as to improve the user experience.

[0038] Embodiment one

[0039] As shown in FIGS. 1-10, the furniture connecting member of the present embodiment comprises a first member 100 and a second member 200, the first member 100 is provided with a slot 110, the second member 200 is provided with a plug-in part 210, the plug-in part 210 is inserted into the slot 110 along a first direction Z, the slot 110 is provided with a first side surface 111, the plug-in part 210 is provided with a second side surface 211, the first side surface 111 and the second side surface 211 are in interference fit, and one of the slot 110 and the plug-in part 210 is provided with a protrusion 300, and the other is provided with a groove 400, the protrusion 300 is inserted into the groove 400 along the first direction Z or in the opposite direction of the first direction Z and in interference fit.

[0040] When the connecting member in the present application is assembled, the plug-in part 210 of the second member 200 can be inserted into the slot 110 along the first direction Z by applying a force to the second member 200 in the first direction Z, and the first side surface 111 and the second side surface 211 are in interference fit, and the protrusion 300 and the groove 400 are also in interference fit. The interference fit can prevent the plug-in part 210 from shaking in the slot 110, thereby ensuring the connection reliability of the first member 100 and the second member 200. Especially when the first direction Z is the direction of gravity, the gravity applied to the second member 200 by the body and the gravity applied to the second member 200 by the user through the body can make the plug-in part 210 and the slot 110 always in interference fit, thereby further improving the connection reliability of the second member 200 and the first member 100. In addition, the entire assembly process does not require any tools, so the assembly of the connecting member is more convenient. Finally, by designing the protrusion 300 and the groove 400, the plug-in part 210 can be effectively limited in at least one direction other than the first direction Z, thereby further improving the connection reliability of the plug-in part 210 and the slot 110.

[0041] Preferably, the interference amount between the first side surface 111 and the second side surface 211 increases with the increase of the insertion depth of the inserting part 210, and the interference amount between the protrusion 300 and the recess 400 increases with the increase of the insertion depth of the inserting part 210. In this way, as the inserting part 210 is inserted deeper into the slot 110, the interference amount between the inserting part 210 and the slot 110 gradually increases, that is, the fit between the inserting part 210 and the slot 110 becomes more and more compact, thereby further improving the connection reliability of the inserting part 210 and the slot 110, and avoiding the connection failure of the inserting part 210 and the slot 110 during use.

[0042] Specifically, the slot 110 in the embodiment has two first side surfaces 111 oppositely arranged, both of which extend along the first direction Z from the mouth of the slot 110 to the bottom wall of the slot 110, and the corresponding inserting part 210 has two second side surfaces 211 oppositely arranged, the distance H1 between the two second side surfaces 211 remains unchanged along the first direction Z, the first side surface 111 includes a first guide segment 1111 and a first fit segment 1112 connected between the first guide segment 1111 and the bottom wall of the slot, the distance H2 between the two first guide segments 1111 is greater than the distance H1 between the two second side surfaces 211, so that the first guide segment 1111 and the second side surface 211 are in clearance fit, and the distance H3 between the two first fit segments 1112 is less than the distance H1 between the two second side surfaces 211, and the distance H3 between the two first fit segments 1112 gradually decreases along the first direction Z, so that the first fit segment 1112 and the second side surface 211 are in interference fit, and the interference amount between them increases with the increase of the insertion depth of the inserting part 210. In this way, through the guidance of the first guide segment 1111, the inserting part 210 can be smoothly inserted into the slot 110, so as to reduce the difficulty of inserting the inserting part 210 into the slot 110, that is, the inserting part 210 is more labor-saving when initially inserted into the slot 110, thereby making the assembly of the connecting member more simple and convenient. In addition, when the first direction Z is the direction of gravity, the gravity of the body acting on the second member 200 and the gravity of the user acting on the second member 200 through the body can make the inserting part 210 be inserted deeper into the slot 110, so that the interference amount between the inserting part 210 and the slot 110 gradually increases, that is, the fit between the inserting part 210 and the slot 110 becomes more and more compact, thereby further improving the connection reliability of the inserting part 210 and the slot 110, and avoiding the connection failure of the inserting part 210 and the slot 110 during use.

[0043] The first fitting sections 1112 in the embodiment are arranged to be inclined inwardly along the first direction Z, so that the distance H3 between the two first fitting sections 1112 gradually decreases along the first direction Z, and the maximum distance between the two first fitting sections 1112 is smaller than the distance H1 between the two second side surfaces 211. In this way, the plug-in part 210 can be smoothly inserted along the first fitting sections 1112, and the existing structure of the second component 200 does not need to be changed, and the processing of the first fitting sections 1112 is facilitated, so that the processing difficulty of the insertion slot 110 is reduced.

[0044] Preferably, the first side surface 111 is an inclined surface arranged to be inclined inwardly along the first direction Z. In this way, the first guiding section 1111 and the first fitting section 1112 can be smoothly connected, so that the plug-in part 210 can be smoothly slid onto the first fitting section 1112 from the first guiding section 1111, the insertion difficulty of the plug-in part 210 is reduced, and the assembly is more labor-saving; in addition, the processing difficulty of the first side surface 111 is reduced, and the processing difficulty of the insertion slot 110 is reduced.

[0045] It can be understood that in other embodiments of the present application, the first fitting section is a stepped surface extending along the first direction Z, the stepped surface includes a plurality of flat surfaces extending along the first direction and guide inclined surfaces connected between adjacent two flat surfaces, the guide inclined surfaces are inclined inwardly along the first direction Z, in this way, the distance between the two first fitting sections can also gradually decrease along the first direction Z.

[0046] In addition, the protrusion 300 in the embodiment is arranged on the bottom wall of the slot 110 and extends along the reverse direction of the first direction Z, the height of the protrusion 300 is less than the depth of the slot 110, one side of the protrusion 300 is connected with the first side surface 111, the width H4 of the protrusion 300 gradually decreases along the reverse direction of the first direction Z, and the recess 400 is arranged on the insertion part 210, the insertion part 210 in the embodiment is a hollow pipe, at this time, the recess 400 includes a first recess 410 penetrating the bottom wall of the insertion part 210 and a second recess 420 penetrating the side wall of the insertion part 210, the first recess 410 and the second recess 420 are communicated, the width H5 of the second recess 420 remains unchanged along the first direction Z, and H5 is between the maximum value and the minimum value of H4, so that the interference amount of the protrusion 300 and the recess 400 increases with the increase of the insertion depth of the insertion part 210. In this way, after the insertion part 210 and the slot 110 are assembled, the protrusion 300 can be hidden to improve the appearance of the connecting member. In addition, when the first direction Z is the direction of gravity, the gravity of the body acting on the second member 200 and the gravity of the user acting on the second member 200 through the body can be used to make the insertion part 210 more deeply inserted into the slot 110, so that the protrusion 300 is more deeply inserted into the recess 400, and the interference amount of the protrusion 300 and the recess 400 gradually increases. That is, the interference amount of the protrusion 300 and the recess 400 increases by superimposing the increase of the interference amount of the first side surface 111 and the second side surface 211, so that the cooperation of the insertion part 210 and the slot 110 is more and more compact, thereby further improving the connection reliability of the insertion part 210 and the slot 110, and avoiding the connection failure of the insertion part 210 and the slot 110 in the use process.

[0047] The second member 200 in the embodiment is a rod-shaped structure extending along the second direction X, the second direction X intersects the first direction Z, and preferably the plane where the second direction X is perpendicular to the first direction Z. The slot 110 has an avoiding opening 112 for avoiding the second member 200, that is, the second member 200 penetrates through the avoiding opening 112. In this way, the insertion part 210 can be limited in the second direction X and the reverse direction thereof by the cooperation of the protrusion 300 and the recess 400, so that the insertion part 210 can be positioned to ensure the accuracy of the insertion position of the insertion part 210 and the slot 110, and the insertion part 210 can be prevented from separating from the slot 110 along the second direction X from the avoiding opening 112, thereby further improving the connection reliability of the insertion part 210 and the slot 110.

[0048] It can be understood that in other embodiments of the present application, the protrusion can also be arranged separately from the first side surface, that is, the protrusion is arranged separately from the first side surface. At this time, the recess only includes the first recess arranged on the bottom wall of the insertion part.

[0049] It can be understood that, in other embodiments of the present application, the recess is arranged on the bottom wall of the slot, and the protrusion is arranged on the bottom wall of the insertion part and extends along the first direction, the protrusion is a taper structure gradually shrinking toward the first direction, and when the insertion part is inserted into the slot, the protrusion is inserted into the recess along the first direction and is in interference fit with the recess, and the interference amount between the protrusion and the recess gradually increases with the depth of the insertion part inserted into the slot.

[0050] It can be understood that, in other embodiments of the present application, the distance between the two first sides along the first direction remains unchanged, the second side includes a second guiding section inserted into the slot in advance and a second fitting section, the distance between the second guiding sections of the two second sides is smaller than the distance between the two first sides, so that the second guiding sections are in clearance fit with the first sides, and the distance between the second fitting sections of the two second sides is greater than the distance between the two first sides, so that the second fitting sections are in interference fit with the first sides, and the interference amount of the two increases with the increase of the insertion depth. In this way, the insertion part can be smoothly inserted into the slot through the guidance of the second guiding section, so as to reduce the difficulty of inserting the insertion part into the slot, that is, the insertion part is more labor-saving in the initial stage of being inserted into the slot, and the assembly of the connecting member is more simple and convenient. In addition, when the first direction is the direction of gravity, the gravity of the body acting on the second member and the gravity of the user acting on the second member through the body can make the insertion part more deeply inserted into the slot, so that the interference amount between the insertion part and the slot gradually increases, that is, the fit between the insertion part and the slot is more and more compact, thereby further improving the connection reliability of the insertion part and the slot, and avoiding the connection failure of the insertion part and the slot during use.

[0051] It can be understood that, in other embodiments of the present application, the protrusion and the recess can also be in clearance fit.

[0052] It can be understood that, in other embodiments of the present application, the second member can also be a solid rod structure.

[0053] It should be noted that, since the connecting member in the embodiment is mainly applied to furniture, especially to the support frame of the furniture, when the support frame is in use, the first direction Z is the direction of gravity.
