Abstract
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] 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. Users assemble the plurality of support rods and the plurality of connecting plates into a support frame by screws. However, in this way, users must use tools to assemble, which makes the installation of the support frame 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 and the second member without the aid of tools, so that the assembly of the connecting member is more convenient. In addition, it can also ensure the connection reliability of the first member and the second member and avoid shaking between the two.
[0004] To solve the above technical problems, the utility model adopts the following technical solutions:
[0005] A connecting member for furniture includes a first member having a slot and a second member having a plug portion. The plug portion is inserted into the slot along a first direction. The slot has a first side surface, and the plug portion has a second side surface. The first side surface and the second side surface are in interference fit; and / or, one of the slot and the plug portion 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 the reverse direction of the first direction and is in interference fit.
[0006] When the connecting member in the present utility model is assembled, by applying a force in the first direction to the second member, the insertion portion of the second member can be inserted into the slot along the first direction, and the first side surface and the second side surface form an interference fit, and / or the protrusion and the groove are inserted into each other to form an interference fit. The interference fit method can prevent the insertion portion from shaking in the slot, thereby ensuring the connection reliability between the first member and the second member. Especially 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 on the second member through the body can be utilized to keep the insertion portion and the slot in an interference fit all the time, so as to further improve the connection reliability between the second member and the first member. In addition, no tools are required for the entire assembly process, so the assembly of the connecting member can be made more convenient. Finally, by designing the protrusion and the groove, the insertion portion can be effectively limited in at least one other direction not parallel to the first direction, so as to further improve the connection reliability between the insertion portion and the slot.
[0007] In the above-mentioned connecting member for furniture, the interference amount between the first side surface and the second side surface increases as the insertion depth of the insertion portion increases; and / or the interference amount between the protrusion and the groove increases as the insertion depth of the insertion portion increases. With such a design, as the insertion portion is inserted deeper into the slot, the interference amount between the insertion portion and the slot can be gradually increased, that is, the fit between 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.
[0008] In the above-mentioned connecting member for furniture, the slot has two first side surfaces arranged oppositely. The first side surface includes a first guiding section and a first fitting section connected between the first guiding section and the bottom wall of the slot. The first guiding section is in clearance fit with the second side surface, and the first fitting section is in interference fit with the second side surface, and the interference amount between the two increases as the insertion depth of the insertion portion increases. With such a design, through the guiding of the first guiding section, the insertion portion can be smoothly inserted into the slot, so as to reduce the difficulty of inserting the insertion portion into the slot, that is, it is more labor-saving for the insertion portion to be initially inserted into the slot, and thus the assembly of the connecting member becomes simpler and more convenient. In addition, 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 on the second member through the body can be utilized to make the insertion portion inserted deeper into the slot, and the interference amount between the insertion portion and the slot is gradually increased, that is, the fit between 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.
[0009] In the above-mentioned connecting member for furniture, the first fitting section is inclined inward 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. With such a design, the insertion part can smoothly continue to insert along the first fitting section, avoiding jamming, without the need to change the structure of the existing second member, and facilitating the processing of the first fitting section to reduce the processing difficulty of the slot.
[0010] In the above-mentioned connecting member for furniture, the first side surface is an inclined surface inclined inward along the first direction. With such a design, the first guiding section and the first fitting section can be smoothly connected, enabling the insertion part to smoothly slide from the first guiding section onto the first fitting section, reducing the insertion difficulty of the insertion part, and thus making the assembly more labor-saving; in addition, it also reduces the processing difficulty of the first side surface, thereby reducing the processing difficulty of the slot.
[0011] In the above-mentioned connecting member for furniture, the second side surface includes a second fitting section and a second guiding section that is inserted into the slot prior to the second fitting section. The second guiding section is in clearance fit with the first side surface, and the second fitting section is in interference fit with the first side surface, and the interference amount between the two increases with the increase of the insertion depth of the insertion part. With such a design, the insertion part can be smoothly inserted into the slot, reducing the difficulty of inserting the insertion part into the slot, that is, it is more labor-saving for the insertion part to be initially inserted into the slot, and thus the assembly of the connecting member is made more simple and convenient; in addition, 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 on the second member through the body can be utilized to make the insertion part insert deeper into the slot, and the interference amount between the insertion part and the slot gradually increases, that is, the fit between the insertion part and the slot becomes more compact, thereby further improving the connection reliability between the insertion part and the slot and avoiding the connection failure between the insertion part and the slot during use.
[0012] In the above-mentioned connecting member for furniture, one of the protrusion and the groove is provided on the first side surface, and the other is provided on the second side surface. The protrusion has a first protrusion surface facing away from the side surface where it is provided, and the groove has a first recessed surface that is in interference fit with the first protrusion surface. The interference amount between the first protrusion surface and the first recessed surface increases with the increase of the insertion depth of the insertion part. With such a design, it is convenient for the user to observe the positions of the protrusion and the groove during assembly, so as to facilitate the user to align the protrusion with the groove, thereby reducing the assembly difficulty of the insertion part and the slot; 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 on the second member through the body can be utilized to make the insertion part insert deeper into the slot, and the protrusion inserts deeper into the groove, and the interference amount between the first protrusion surface and the first recessed surface gradually increases, that is, the fit between the insertion part and the slot becomes more compact, thereby further improving the connection reliability between the insertion part and the slot and avoiding the connection failure between the insertion part and the slot during use.
[0013] In the above-mentioned connecting member for furniture, the protrusion has a second protrusion surface connected between the first protrusion surface and the provided side surface, the groove has a second concave surface in interference fit with the second protrusion surface, and the interference amount between the second protrusion surface and the second concave surface increases as the insertion depth of the insertion portion increases. With such a design, as the insertion depth of the protrusion increases, the fitting tightness between the protrusion and the groove can be further increased, so as to improve the connection reliability between the insertion portion and the slot.
[0014] In the above-mentioned connecting member for furniture, the protrusion is provided on the bottom wall of the slot and extends along the reverse direction of the first direction, the groove is provided on the insertion portion, and the interference amount between the protrusion and the groove increases as the insertion depth of the insertion portion increases. With such a design, after the insertion portion and the slot are assembled, the protrusion can be hidden to improve the appearance of the connecting member; in addition, 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 on the second member through the body can be utilized to make the insertion portion insert deeper into the slot, and thus the protrusion inserts deeper into the groove, and the interference amount between the protrusion and the groove gradually increases, that is, the fit between 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.
[0015] 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 is possible to 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.
[0016] 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 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.
[0017] 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.

[0039] Embodiment 1
[0040] As Figures 1 to 10 shown, the furniture connecting member of this embodiment includes a first member 100 and a second member 200. The first member 100 is provided with a slot 110, and the second member 200 has an insertion portion 210. The insertion portion 210 is inserted into the slot 110 along the first direction Z. The slot 110 has a first side surface 111, and the insertion portion 210 has a second side surface 211. The first side surface 111 and the second side surface 211 form an interference fit, and one of the slot 110 and the insertion portion 210 is provided with a protrusion 300, and the other is provided with a groove 400. The protrusion 300 is inserted and forms an interference fit with the groove 400 along the first direction Z or along the reverse of the first direction Z.
[0041] When assembling the connecting member in the present utility model, by applying a force in the first direction Z to the second member 200, the insertion portion 210 of the second member 200 can be inserted into the slot 110 along the first direction Z, and the first side surface 111 and the second side surface 211 form an interference fit. At the same time, the protrusion 300 and the groove 400 can also be inserted to form an interference fit. The interference fit method can prevent the insertion portion 210 from shaking in the slot 110, thereby ensuring the connection reliability between the first member 100 and the second member 200. Especially when the first direction Z is the downward gravity direction, the gravity exerted by the body on the second member 200 and the gravity exerted by the user himself on the second member 200 through the body can be utilized to make the insertion portion 210 and the slot 110 always maintain an interference fit, so as to further improve the connection reliability between the second member 200 and the first member 100. In addition, no tools are required for the entire assembly process, so the assembly of the connecting member can be made more convenient. Finally, by designing the protrusion 300 and the groove 400, the insertion portion 210 can be effectively limited in at least one other direction not parallel to the first direction Z, so as to further improve the connection reliability between the insertion portion 210 and the slot 110.
[0042] 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 insertion portion 210; and the interference amount between the protrusion 300 and the groove 400 increases with the increase of the insertion depth of the insertion portion 210. With such a design, as the insertion portion 210 is inserted deeper into the slot 110, the interference amount between the insertion portion 210 and the slot 110 can be gradually increased, that is, the fit between the insertion portion 210 and the slot 110 becomes more and more compact, thereby further improving the connection reliability between the insertion portion 210 and the slot 110 and avoiding the connection failure between the insertion portion 210 and the slot 110 during use.
[0043] Specifically, the slot 110 in this embodiment has two first side surfaces 111 arranged oppositely, and both of the two first side surfaces 111 extend along the first direction Z from the socket of the slot 110 towards the bottom wall of the slot. Correspondingly, the plug-in portion 210 has two second side surfaces 211 arranged oppositely, and 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 guiding section 1111 and a first mating section 1112 connected between the first guiding section 1111 and the bottom wall of the slot. The distance H2 between the two first guiding sections 1111 is greater than the distance H1 between the two second side surfaces 211, so that the first guiding section 1111 is in clearance fit with the second side surface 211, while the distance H3 between the two first mating sections 1112 is less than the distance H1 between the two second side surfaces 211, and the distance H3 between the two first mating sections 1112 gradually decreases along the first direction Z, so that while the first mating section 1112 is in interference fit with the second side surface 211, the interference amount between the two can also increase with the increase of the insertion depth of the plug-in portion 210. With such a design, through the guidance of the first guiding section 1111, the plug-in portion 210 can be smoothly inserted into the slot 110, so as to reduce the difficulty of inserting the plug-in portion 210 into the slot 110, that is, it will be more labor-saving for the plug-in portion 210 to be initially inserted into the slot 110, and further make the assembly of the connecting member simpler and more convenient; in addition, when the first direction Z is the downward gravity direction, the gravity exerted by the main body on the second member 200 and the gravity exerted by the user on the second member 200 through the main body can be utilized to make the plug-in portion 210 insert deeper into the slot 110, that is, the interference amount between the plug-in portion 210 and the slot 110 gradually increases, that is, the fit between the plug-in portion 210 and the slot 110 becomes more and more compact, thereby further improving the connection reliability between the plug-in portion 210 and the slot 110 and avoiding the connection failure between the plug-in portion 210 and the slot 110 during use.
[0044] The first mating section 1112 in this embodiment is inclined inwards along the first direction Z, so that the distance H3 between the two first mating sections 1112 gradually decreases along the first direction Z, and the maximum distance between the two first mating sections 1112 is less than the distance H1 between the two second side surfaces 211. With such a design, it can not only enable the plug-in portion 210 to continue to be smoothly inserted along the first mating section 1112 to avoid jamming, but also does not need to change the structure of the existing second member 200, and is beneficial to the processing of the first mating section 1112 to reduce the processing difficulty of the slot 110.
[0045] Preferably, the first side surface 111 is an inclined surface that is inclined inward along the first direction Z. With such a design, the first guiding section 1111 and the first mating section 1112 can be smoothly connected, enabling the plugging portion 210 to smoothly slide from the first guiding section 1111 onto the first mating section 1112, thereby reducing the insertion difficulty of the plugging portion 210 and making the assembly more labor-saving. In addition, the processing difficulty of the first side surface 111 is also reduced, thereby reducing the processing difficulty of the slot 110.
[0046] It can be understood that in other embodiments of the present invention, the first mating 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 guiding inclined surfaces connected between adjacent flat surfaces. The guiding inclined surfaces are inclined inward along the first direction Z. With such a design, the distance between the two first mating sections can also be gradually reduced along the first direction Z.
[0047] In addition, the protrusion 300 in this embodiment is provided on the bottom wall of the slot 110 and extends in the reverse direction of the first direction Z. The height of the protrusion 300 is less than the depth of the slot 110, and one side of the protrusion 300 is connected to the first side surface 111. The width H4 of the protrusion 300 gradually decreases in the reverse direction of the first direction Z, while the groove 400 is provided on the plugging portion 210. The plugging portion 210 in this embodiment is a hollow tube. At this time, the groove 400 includes a first groove 410 penetrating the bottom wall of the plugging portion 210 and a second groove 420 penetrating the side wall of the plugging portion 210. The first groove 410 and the second groove 420 are communicated. The width H5 of the second groove 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 between the protrusion 300 and the groove 400 increases as the insertion depth of the plugging portion 210 increases. With such a design, after the plugging portion 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 downward gravity direction, the gravity exerted by the main body on the second member 200 and the gravity exerted by the user on the second member 200 through the main body can be utilized to make the plugging portion 210 deeper into the slot 110, that is, the protrusion 300 is deeper into the groove 400, and the interference amount between the protrusion 300 and the groove 400 gradually increases. That is, by increasing the interference amount between the first side surface 111 and the second side surface 211 and superimposing the increase in the interference amount between the protrusion 300 and the groove 400, the fit between the plugging portion 210 and the slot 110 can be made more compact, thereby further improving the connection reliability between the plugging portion 210 and the slot 110 and avoiding the connection failure between the plugging portion 210 and the slot 110 during use.
[0048] In this embodiment, the second component 200 is a rod-shaped structure extending along the second direction X, the second direction X intersects with the first direction Z, and preferably, the plane where the second direction X is located is perpendicular to the first direction Z. The slot 110 has a avoidance opening 112 for avoiding the second component 200, that is, the second component 200 is arranged through the avoidance opening 112. In this way, the plug-in portion 210 can be limited in the second direction X and its reverse direction by the cooperation of the protrusion 300 and the groove 400, which can not only position the plug-in portion 210 to ensure the accuracy of the plug-in position of the plug-in portion 210 and the slot 110, but also prevent the plug-in portion 210 from escaping from the slot 110 along the second direction X from the avoidance opening 112, thereby further improving the connection reliability between the plug-in portion 210 and the slot 110.
[0049] It is understandable that in other embodiments of the present invention, the protrusion may not be connected to the first side surface, that is, the protrusion is spaced apart from the first side surface, and in this case, the groove only includes the first groove provided on the bottom wall of the plug-in portion.
[0050] It can be understood that in other embodiments of the present invention, the groove is provided on the bottom wall of the slot, and the protrusion is provided on the bottom wall of the plug-in part and extends along the first direction, the protrusion is a cone structure that gradually shrinks toward the first direction, and when the plug-in part is inserted into the slot, the protrusion is inserted into the groove along the first direction and has an interference fit with the groove, and the interference amount between the protrusion and the groove gradually increases with the depth of the plug-in part inserted into the slot.
[0051] It can be understood that in other embodiments of the present invention, the distance between the two first side surfaces along the first direction remains unchanged, the second side surface includes a second mating section and a second guide section inserted into the slot before the second mating section, the distance between the second guide sections of the two second side surfaces is smaller than the distance between the two first side surfaces, so that the second guide section and the first side surface have a clearance fit, and the distance between the second mating sections of the two second side surfaces is larger than the distance between the two first side surfaces, so that the second mating section and the first side surface have an interference fit, and the interference amount of the two increases with the increase of the insertion depth of the plug-in portion. With such a design, the plug-in part can be smoothly inserted into the slot through the guidance of the second guide section, so as to reduce the difficulty of inserting the plug-in part into the slot, that is, the initial insertion of the plug-in part into the slot will be more labor-saving, thereby making the assembly of the connecting component simpler and more convenient; in addition, 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 utilized to make the plug-in part deeper into the slot, which also makes the interference fit between the plug-in part and the slot gradually increase, that is, the fit between the plug-in part and the slot becomes more and more compact, thereby further improving the connection reliability between the plug-in part and the slot, and avoiding failure of the connection between the plug-in part and the slot during use.
[0052] It can be understood that in other embodiments of the present utility model, the protrusion and the groove may also be in clearance fit.
[0053] It can be understood that in other embodiments of the present utility model, the second member may also be a solid rod-shaped structure.
[0054] 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 gravity direction. 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, so that the insertion portion 210 can be inserted deeper into the slot 110, and thus the interference amount between the insertion portion 210 and the slot 110 gradually increases, that is, the fit between the insertion portion 210 and the slot 110 becomes tighter and tighter. Thereby, the connection reliability between the insertion portion 210 and the slot 110 is further improved, and the connection failure between the insertion portion 210 and the slot 110 during use is avoided.
[0055] 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. For example, Figure 2 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, so that the end parts of the two second members 200 can be respectively inserted into the two slots 110 of the L-shaped insert block, so that the two second members 200 are distributed vertically, that is, the extension directions of the two second members 200 are perpendicular to each other; for example, Figure 7 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, so that the two second members 200 are distributed in a straight line, that is, the two second members 200 extend along the same straight line; for example, Figure 8 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, so that the three second members 200 are 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; for example, Figure 9As shown, the first member 100 may 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, so that the four second members 200 are distributed in a cross shape. With such a design, the first member 100 of different shapes can be configured according to the distribution of the second members 200 to meet the assembly requirements of different support frames.
[0056] As Figure 10 As 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, and the plurality of support rods are connected by a plurality of first members 100 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.
[0057] 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. Two intermediate long rods extending along the same straight line and two intermediate short rods perpendicular to the intermediate long rods are provided inside the bed frame. 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, and the long side and the short side are spliced by an L-shaped insert block.
[0058] 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.
[0059] It can be understood that in other embodiments of the present invention, if the intermediate long rods and the intermediate short rods of the bed frame are omitted, 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.
[0060] In addition, the support frame further includes feet 500 for supporting the first member 100. The first member 100 is provided with an insert block 120 independently processed and formed. The insert block 120 is fixed to the first member 100 by means of screw connection or welding. The top of the foot 500 is provided with a jack for the insert block 120 to be inserted. With such a design, the assembly of the foot 500 and the first member 100 can be made convenient to further reduce the assembly difficulty of the support frame.
[0061] It can be understood that in other embodiments of the present utility model, the first member is provided with a jack, and the top of the support leg is inserted into the jack. With such a design, the assembly of the first member and the support leg can also be facilitated.
[0062] Finally, this embodiment also discloses a piece of furniture, including a body and a support frame for supporting the body. The furniture is a bed, the body is a mattress, and the support frame is a bed frame.
[0063] It can be understood that in other embodiments of the present utility model, the furniture can also be a sofa. At this time, the body is a sofa cushion and the support frame is a sofa frame; or the furniture is a table, a chair, outdoor furniture, etc.
[0064] Embodiment 2
[0065] As Figure 11 and Figure 12 shown, compared with Embodiment 1, the difference in this embodiment is that the first side surface 111 can be in clearance fit with the second side surface 211. At this time, the protrusion 300 is provided on the second side surface 211, and the groove 400 is provided on the first side surface 111. The protrusion 300 has a first protruding surface 310 facing away from the second side surface 211, and the groove 400 has a first concave surface 401 that is in interference fit with the first protruding surface 310. The interference amount between the first protruding surface 310 and the first concave surface 401 increases as the insertion depth of the insertion portion 210 increases. With such a design, it is convenient for the user to observe the positions of the protrusion 300 and the groove 400 during assembly, so as to facilitate the user to align the protrusion 300 with the groove 400, thereby reducing the assembly difficulty of the insertion portion 210 and the slot 110; when the first direction Z is the downward gravity direction, the gravity exerted by the body on the second member 200 and the gravity exerted by the user on the second member 200 through the body can be utilized to make the insertion portion 210 deeper into the slot 110, that is, the protrusion 300 deeper into the groove 400, and the interference amount between the first protruding surface 310 and the first concave surface 401 gradually increases, that is, the fit between the insertion portion 210 and the slot 110 becomes tighter, thereby further improving the connection reliability between the insertion portion 210 and the slot 110 and avoiding the connection failure between the insertion portion 210 and the slot 110 during use.
[0066] Specifically, the height by which the first convex surface 310 in this embodiment protrudes from the second side surface 211 gradually decreases along the first direction Z, so that the distance H6 between the two first convex surfaces 310 gradually decreases along the first direction Z, while the recess depth of the first concave surface 401 gradually decreases along the first direction Z, so that the distance H7 between the two first concave surfaces 401 gradually decreases, and the minimum value of H6 is between the maximum value and the minimum value of H7. With such a design, it is convenient for the protrusion 300 to be smoothly inserted into the groove 400, and the interference amount between the first convex surface 310 and the first concave surface 401 increases as the insertion depth of the insertion portion 210 increases.
[0067] In addition, the protrusion 300 in this embodiment further has a second convex surface 320 connected between the first convex surface 310 and the second side surface 211. The second convex surface 320 is provided on opposite sides of the first convex surface 310 and extends along the first direction Z. The distance between the two second convex surfaces 320 gradually decreases along the first direction Z, that is, the protrusion 300 is an isosceles trapezoid that is larger at the top and smaller at the bottom. The groove 400 has a second concave surface 402 that is in interference fit with the second convex surface 320. The second concave surface 402 is in interference fit with the second convex surface 320. The groove 400 is an isosceles trapezoid groove that is larger at the top and smaller at the bottom. The minimum distance between the two second convex surfaces 320 is between the maximum distance and the minimum distance of the two second concave surfaces 402. In this way, the interference amount between the second convex surface 320 and the second concave surface 402 can increase as the insertion depth of the insertion portion 210 increases, so as to further increase the fitting tightness between the protrusion 300 and the groove 400 and improve the connection reliability between the insertion portion 210 and the slot 110.
[0068] It can be understood that in other embodiments of the present utility model, the protrusion can also be provided on the first side surface. At this time, the protrusion has a first convex surface facing away from the first side surface. The height by which the first convex surface protrudes from the first side surface gradually increases along the first direction, while the groove is provided on the second side surface. The groove has a first concave surface that is in interference fit with the first convex surface. The recess depth of the first concave surface gradually increases along the first direction. With such a design, the interference amount between the first convex surface and the first concave surface can also increase as the insertion depth of the insertion portion increases.
[0069] The above is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that the present utility model includes but is not limited to the content described in the drawings and the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present utility model will be included in the scope of the claims.
