The interior of the expansion body 4 is hollow. The first member 10 needs to be pre-processed with holes, and the expansion body 4 is inserted into the holes of the first member 10 through clearance fit. One end of the first fastener 3 may have an external thread structure, or the cross-section of one end of the first fastener 3 may be oval, round, or rectangular, so that one end of the first fastener 3 can be inserted into the expansion body 4 and It can rotate within the expansion body 4. When the first fastener 3 rotates in a predetermined direction (usually clockwise), the first fastener 3 drives at least a part of the expansion body 4 to expand outward, thereby driving the fastening protrusion 41 The expansion body 4 expands outward in the radial direction and presses against the inner wall of the hole of the first member 10 , thereby fastening the first fastener 3 to the first member 10 .

In some embodiments, the diameter of the expansion body 4 is 4 to 6.5 mm. Because the diameter of the expansion body 4 is small, when the user removes the second member 20, the expansion body 4 can be left in the reserved hole of the first member 10 as a filler for the reserved hole. Improve the aesthetics of the furniture; wherein, the color of the expansion body 4 can be consistent with the surface color of the first component 10 .

In some embodiments, as shown in Figures 2 to 3 and 16, the notch of the adjustment groove 123 is in the shape of a countersunk head. Specifically, the edge of the notch of the adjustment groove 123 extends circumferentially outward, so that the groove of the adjustment groove 123 The width of the opening is greater than or equal to the diameter of the head of the first fastener 3 . When the first fastener 3 is inserted into the adjustment groove 123 from the connection side 122, the head of the first fastener 3 is embedded in the adjustment groove 123, so that the head of the first fastener 3 is lower than the connection side 122 or the third The end face of the head of a fastener 3 is located on the same plane as the connecting side 122, so that the user cannot see the head of the first fastener 3, which improves the aesthetics and avoids or reduces the distance between the head of the first fastener 3 and the connecting side 122. The inner side walls of the chute 21 interfere with each other during the relative sliding process, ensuring that the second connector 2 is smoothly slid and inserted into the plug-in part 12 through the chute 21 .

In some embodiments, in order to generate a lateral pulling force between the first connecting member 1 and the second connecting member 2, or to enhance the lateral pulling force between the first connecting member 1 and the second connecting member 2, so as to avoid or reduce the lateral pulling force of the first connecting member 1 and the second connecting member 2 in the connected state. One member 10 and the second member 20 are separated in the horizontal direction (the transverse direction in this embodiment refers to the direction in which the first member 10 and the second member 20 are separated from each other in the horizontal direction after they are connected), resulting in that the first member 10 and the second member 20 are separated from each other in the horizontal direction. There is a large gap between the second member 20 or the second member 20 falls. As shown in Figures 2 to 4, 8 to 9, and 14 to 17, the plug portion 12 of this embodiment 1 At least one boss 124 is formed on one end away from the support portion 11 . The boss 124 can be integrally formed on the plug-in portion 12 . An insertion hole 22 is formed on the inner surface of the upper end of the slide groove 21 for mating with the boss 124 . , at least a portion of the boss 124 is inserted into the socket 22 . When viewed along the longitudinal X direction, the cross-sectional area of the boss 124 is smaller than the cross-sectional area of the plug-in part 12 . During assembly, the slide groove 21 of the second connector 2 slides and nests in the insertion portion 12 of the first connector 1 along the longitudinal direction X, and at least a part of the boss 124 is inserted into the socket 22 . Since the boss 124 increases the contact area of the first connecting member 1 and the second connecting member 2 in the lateral direction, the tensile load capacity in the lateral direction between the first connecting member 1 and the second connecting member 2 is formed or increased. At the same time, since the boss 124 of the first connecting member 1 is inserted into the socket 22 of the second connecting member 2, a part of the first connecting member 1 and a part of the second connecting member 2 are nested with each other to form a limiting first connection. The resistance of the first connection part 1 and the second connection part 2 to separate from each other in the transverse direction forms or increases the tensile load capacity of the first connection part 1 and the second connection part 2 in the transverse direction, thereby improving the connection between the first connection part 1 and the second connection part 2. The connection firmness between the components 2 can effectively avoid or reduce the risk of the first connector 1 and the second connector 2 being separated from each other due to deformation of the first component 10 or the second component 20, and improve the relationship between the first component 10 and the second connector 2. The connection stability and load capacity between the two components 20.

Among them, the boss 124 can be partially inserted into the jack 22, or can be completely inserted into the jack 22. When the boss 124 is completely inserted into the jack 22, the first connector 1 and the second connector 2 move along the transverse direction. The larger contact area further increases the transverse tensile load capacity between the first connecting piece 1 and the second connecting piece 2 . The socket 22 may be a blind hole or a through-hole structure. When the socket 22 is a through-hole structure, the socket 22 extends along the longitudinal direction The insertion volume increases the tensile load capacity of the first connecting member 1 and the second connecting member 2 in the transverse direction.

In the present invention, Embodiment 1 does not limit the number, position and specific shape of the bosses 124. For example, the bosses 124 can be one or more, and the number of the sockets 22 can also be one or more. Preferably, the bosses 124 can be one or more. The number and position of the stations 124 can correspond to the number and position of the jacks 22 one-to-one. For example, as shown in FIGS. 2 to 4 and 8 to 9 , the number of bosses 124 in Embodiment 1 is preferably one and the number of jacks 22 is one. One boss 124 is inserted into one jack 22 , which is beneficial to The preparation process of the first connector 1 is simplified and the preparation efficiency is improved. The shape of the boss 124 can be cylindrical, conical, protruding, rectangular, prism-shaped or other irregular shapes. The shape and size of the socket 22 are adapted to the shape and size of the boss 124. , to ensure that the boss 124 is smoothly inserted into the socket 22, and at the same time, the gap between the boss 124 and the socket 22 is small, thereby improving the transverse tightening effect of the first connector 1 and the second connector 2.

The boss 124 and the plug-in part 12 can be an integrally formed structure, such as an integrally formed metal piece, processed through a mold or cold heading or die-casting process, so that the overall structure is firm and stable.

In some embodiments, as shown in FIGS. 16 to 17 , an embedding groove 125 is formed on one end of the plug portion 12 away from the supporting portion 11 , and an embedding groove 125 is formed on the inner surface of the upper end of the slide groove 21 to cooperate with the embedding groove 125 . Set of embedded blocks 25. The shape of the embedded block 25 may be a cube shape, a cylinder shape, a convex point shape, etc. In this way, through the concave and convex cooperation between the embedded block 25 and the embedded groove 125, the first connecting member 1 and the second connecting member 2 are accurately positioned and the lateral pulling force is increased, thereby reducing the friction between the first member 10 and the second member 20. gap between them to improve the stability of the connection. Because the material price of the first connecting piece 1 per unit volume is usually higher than the material price of the second connecting piece 2, for example, usually the first connecting piece 1 is a metal piece and the second connecting piece 2 is a plastic piece, the embedded block 25 and the embedded groove The arrangement of 125 not only increases the volume of the second connecting member 2, but also reduces the volume of the first connecting member 1, thereby saving costs.

In some embodiments, as shown in FIGS. 2 to 3 , 5 to 7 , and 13 to 17 , at least one protrusion 13 is formed on the connecting side 122 and/or the upper surface of the bracket 11 . The protrusion 13 may be located on the connecting side 122 , or on the upper surface of the supporting portion 11 , or on both the connecting side 122 and the upper surface of the supporting portion 11 . The protrusion 13 can increase the connection strength between the plug-in part 12 and the holder part 11, so that the plug-in part 12 and the holder part 11 form a stronger whole, increase the overall reinforcement of the first connector 1, and improve the second The gravity load capacity of a connecting member 1 to the second member 20 and the second connecting member 2.

Further, as shown in FIGS. 18 and 19 , in order to make the second connector 2 embedded in the second member 20 , a mounting groove 201 is processed at the bottom of the side of the second member 20 through a drilling process. The lower end of the mounting groove 201 The side faces penetrate through the bottom of the second member 20. During installation, the second connector 2 is embedded into the installation groove 201, and the opening at the lower end of the slide groove 21 is connected with the opening at the lower end of the installation groove 201. Among them, the second connecting member 2 can be embedded in the installation groove 201 through interference fit. In some embodiments, in order to improve the installation firmness of the second connector 2 on the second member 20, as shown in Figures 1 to 2 and 6 to 7, the connection assembly of this embodiment 1 also includes a second Fastener 5, the second fastener 5 penetrates the side of the second connector 2, and the head of the second fastener 5 is located in the chute 21, and the tail of the second fastener 5 is fastened to the second member 20 superior. The second fastener 5 can be a fastener with an external thread structure, such as a screw, a bolt, a stud, etc. When the second fastener 5 is a screw, it can be installed in the chute 21 through self-drilling. A perforation is drilled on the inner side of the second fastener 5 for the second fastener 5 to pass through, and then the second fastener 5 is self-tappingly fastened to the inner side of the installation groove 201; when the second fastener 5 is a bolt or stud, such as As shown in Figures 10 to 12, it is necessary to preset perforations on the inner surface of the chute 21, and a slot hole is provided at the corresponding inner position of the installation groove 201, and the second fastener 5 is used to pass through the second connector 2 After being perforated, it is fastened to the slot hole of the installation groove 201 , so that the second connecting member 2 is firmly fixed in the installation groove 201 .

Furthermore, since the gravity load borne by the second connecting member 2 acts on the supporting portion 11 of the first connecting member 1, the supporting portion 11 is subject to a larger moment, and the second member 20 is prone to be overloaded by the gravity load. The first member 10 or the second member 20 causes damage, for which, in some embodiments, as shown in FIGS. 6-7 , the head of the second fastener 5 abuts or is close to the top of the protrusion 13 . In this way, when the second member 20 and the second connector 2 bear a gravity load, the gravity load of a part of the second member 20 acts on the supporting part 11 , and the gravity load of another part of the second member 20 acts through the second fastener 5 On the protrusion 13, since the protrusion 13 has a shorter moment arm relative to the center of the first connecting member 1, the protrusion 13 bears a smaller moment, that is, it can withstand a greater gravity load, thereby effectively increasing the load of the first connecting member 1. Ability to avoid or reduce damage to the connection between the first connector 1 and the second connector 2, and improve the connection stability and load capacity between the first member 10 and the second member 20.

The shape of the contact portion 23 can be cylindrical, block-like, or other irregular shapes, and the number can be one or more, which is not limited here. The contact portion 23 and the second connecting member 2 may have an integrally formed structure. After the first connector 1 and the second connector 2 are assembled, the contact portion 23 abuts or is close to the top of the protrusion 13 , so that when the second member 20 and the second connector 2 bear gravity load, the second member The gravity load of part of the second member 20 acts on the supporting part 11, and the gravity load of the other part of the second member 20 directly acts on the protrusion 13 through the abutment part 23, because the protrusion 13 has a shorter force arm relative to the center of the first connecting member 1 , therefore the protrusion 13 bears a smaller moment, that is, it can withstand a larger gravity load, thereby effectively improving the load capacity of the first connector 1 and improving the connection stability and load between the first member 10 and the second member 20 ability.

It should be further noted that in the present invention, Embodiment 1 does not limit the structure, shape and number of the protrusions 13. For example, the protrusions 13 may be in the shape of a cylinder, a square prism, or other regular or irregular structures. The number of 13 may be one or more. For example, the plurality of protrusions 13 may be spaced apart from each other. When the second member 20 and the second connector 2 bear gravity load, the tops of the plurality of protrusions 13 may be connected to the second fastener 5 together. The head or abutment portion 23 cooperates with the abutment, and multiple protrusions 13 contact at the same time, thereby increasing the contact area and stronger gravity load capacity. For example, as shown in Figures 2 to 3, 7, 13 to 14, and 16, the number of protrusions 13 is two, and the two protrusions 13 are relatively spaced apart along the transverse direction Y on the connecting side 122. The tops of the two protrusions 13 can abut against the head or abutment portion 23 of the second fastener 5 together, thereby improving the load capacity of the second member 20 and the second connector 2 .

In some embodiments, as shown in FIGS. 3 and 16 , the protrusion 13 includes a support section 131 , which is provided on the connecting side 122 and extends to the support portion 11 along the longitudinal direction X.

The reinforcing section 132 can extend to the connecting side 122 . In still other embodiments, the protrusion 13 includes a support section 131 and a reinforcement section 132. The support section 131 is provided on the connecting side 122 and extends to the support portion 11 along the longitudinal direction X. The reinforcement section 132 is provided on the upper surface of the support portion 11 and extends along the longitudinal direction X. Lateral extension. Among them, the support sections 131 and the reinforcement sections 132 can be connected, and the number of the support sections 131 and the number of the reinforcement sections 132 can be the same or different. For example, one support section 131 is connected to one reinforcement section 132, and for example, one support section 131 is connected to two sections. Reinforcement section 132. In this way, when the second member 20 and the second connector 2 bear a gravity load, the second fastener 5 or the contact portion 23 can contact the top of the support section 131, and the support section 131 is used to bear the gravity load to raise the second member 20 And the load-bearing capacity of the second connecting piece 2. The reinforcing section 132 increases the thickness of the supporting portion 11 to a certain extent, so that when the bottom of the second connecting member 2 abuts against the supporting portion 11 , the bearing capacity of the supporting portion 11 is effectively increased, thereby improving the quality of the second member 20 and the second supporting portion 11 . The load-bearing capacity of the connector 2 can be reduced by reducing the thickness of the bracket 11 to save costs, or by maintaining the thickness of the bracket 11 and increasing the load-bearing capacity with only a small increase in cost. Among them, when the protrusion 13 has a large transverse length or the length of the reinforcing section 132 is large, in order to ensure that the bottom of the second connecting member 2 contacts the bracket 11 , the bottom of the second connecting member 2 is provided with a position corresponding to the protrusion 13 The corresponding avoidance notch 24, the specific position and number of the avoidance notch 24 correspond to the number of positions of the reinforcing sections 132. The protrusion 13 or the reinforcing section 132 can contact the avoidance gap 24 to improve the bearing capacity of the supporting portion 11 .

In other embodiments, the tops of the protrusions 13 are flat or wavy or have other irregular shapes.

In some embodiments, since the mounting groove 201 on the second component 20 is usually processed by a drilling process, the bottom of the mounting groove 201 is an arc surface. In order to adapt to the shape of the mounting groove 201, as shown in Figure 1 to As shown in Figures 2, 8, 10 to 12, and 14 to 15, the outer surface of the second connector 2 is an arc surface, and the curvature of the arc outer surface of the second connector 2 is based on the installation groove. The curvature of the groove bottom 201 is adapted accordingly, such as 110°, 120° or 130°, etc., which is not limited here. At the same time, in order to improve the invisibility of the installation groove 201 of the second member 20, the outer circumferential diameter of the outer surface of the second connector 2 is 6-10 mm, such as 6 mm, 8 mm, 10 mm, etc. At the same time, the boss 124 of this embodiment 1 strengthens or enables the first connecting piece 1 and the second connecting piece 2 to have lateral binding force; the protrusion 13 strengthens the first connecting piece 1 to the second connecting piece 2 and/or the second member.
