Description

TECHNICAL FIELD

[0001] The utility model relates to a connecting piece, connecting assembly and connecting system for connecting a first component and a second component, in particular for connecting furniture components. BACKGROUND

[0002] At present, with the continuous improvement of people's aesthetic concept, invisible connection between two furniture plates or two metal components is gradually realized by using invisible connecting pieces, thereby improving the appearance of furniture or equipment. Some existing layer plates and cabinet bodies are detachably connected by layer plate holders. For example, the layer plate holder disclosed in Chinese Patent No. CN102133002B is used by mounting the female piece on the layer plate and the male piece on the inner side wall of the cabinet body, and then the layer plate and the cabinet body are connected by the female piece and the male piece, so that the layer plate is assembled in the cabinet body, which is detachable and has high appearance. In order to prevent the side plate from falling off due to material deformation after long-term use of the cabinet body, the female piece and the male piece are clamped by the pawl and the insertion part to form a large transverse tension, which limits the separation of the female piece and the male piece in the transverse direction, thereby improving the connection stability between the layer plate and the cabinet body. However, when the diameter of the outer periphery of the female piece is small (for example, 6mm or 8mm or 10mm), the thickness of the pawl on the female piece becomes small and the contact area between the pawl and the insertion part is small, which reduces the transverse load capacity between the female piece and the male piece, causing the female piece and the male piece to easily separate in the transverse direction, thereby causing a gap between the layer plate and the cabinet plate or even causing the layer plate to fall off. At the same time, when the diameter of the outer periphery of the female piece is small (for example, 6mm or 8mm or 10mm), the installation slot on the layer plate is of a corresponding diameter. When the installation slot on the layer plate is small (for example, 6mm or 8mm or 10mm), the installation slot has a small transverse load capacity for the female piece, which is insufficient to resist the deformation of the cabinet plate, thereby causing a gap between the layer plate and the cabinet plate or even causing the layer plate to fall off.

[0003] For example, the first connecting piece, connecting assembly and connecting system disclosed in Chinese Patent No. CN217539244U are used when the second connecting piece bears a load from top to bottom. A part of the second connecting piece bears a load from top to bottom on the support part, and another part of the second connecting piece bears a load from top to bottom on the support protrusion through the fastener or directly on the support protrusion. Since the force arm of the support protrusion relative to the center of the first connecting piece is short, the torque borne by the support protrusion is small, i.e. it can bear a larger load from top to bottom, thereby improving the connection stability and load capacity between the first component and the second component. However, the main purpose of the support protrusion is to improve the load bearing capacity of the load from top to bottom, without considering the connection stability of the first component and the second component in the horizontal direction.

[0004] For example, the Chinese patent No. CN217653038U discloses a first connecting piece, a connecting assembly and a connecting system. When in use, the first connecting piece is installed on the first component, and the boss and the supporting portion are sequentially arranged in the up-down direction. The bottom of the side surface of the second component is provided with a mounting groove, and the second connecting piece is embedded in the mounting groove. The second component and the second connecting piece are slidably nested on the insertion portion. At least a part of the boss of the first connecting piece is inserted into the insertion hole. The boss increases the contact area of the first connecting piece and the second connecting piece in the transverse direction, thereby increasing the transverse tensile load capacity between the first connecting piece and the second connecting piece. However, when the mounting groove and the insertion hole are opened, the process is complex, and the size of the mounting groove on the second component is prone to machining errors, which may cause the boss of the first connecting piece to fail to be smoothly inserted into the insertion hole on the second connecting piece, resulting in installation difficulties. Or when the mounting groove and the insertion hole are opened at the same time, a second tool is needed, which may cause the use of tools to be inconsistent. In addition, because the diameter of the insertion hole is small, the drill is prone to wear, which may cause burrs in the hole, making it difficult for the boss to be inserted. In some cases, the insertion hole is prone to be opened to the side surface of the layer plate, which may also cause gaps between the layer plate and the cabinet plate, or even cause the layer plate to fall off. Practical new type content

[0005] To solve the technical problems of the existing technology, such as the complex structure of the layer plate holder, the poor connection stability of the layer plate holder, the difficulty in installing the layer plate holder, and the displacement of the layer plate in the horizontal direction after the installation of the layer plate holder, which may cause gaps between the cabinet plate and the layer plate, the first aspect of the present application provides a connecting piece for connecting a first component and a second component. The bottom of the side surface of the second component is provided with a mounting groove. The connecting piece comprises a connecting piece body, which comprises a supporting portion and an insertion portion arranged on the supporting portion. One side of the insertion portion is used for being installed on the first component, and at least a part of the insertion portion is used for being inserted into the mounting groove of the second component from bottom to top.

[0048] As Figures 1-3 The utility model discloses a connecting piece 1 for connecting first component 10 and second component 20, the side bottom of second component 20 is provided with installation slot 201, wherein, connecting piece 1 includes connecting piece body, and the connecting piece body includes the support portion 11 and the plug-in portion 12 set on the support portion 11, one side of plug-in portion 12 is used to install on first component 10, and at least a part of plug-in portion 12 is used to cooperate from below to above and insert into the installation slot 201 of second component 20;The end of the plug-in portion 12 away from the support portion 11 is formed with at least one protruding portion 13, and / or, the support portion 11 is formed with at least one protruding portion 13;At least a part of protruding portion 13 is used to insert from below to above into second component 20.

[0049] When using assembly, first, one side of plug-in portion 12 is fixedly installed on first component 10, and installation slot 201 is set on the side bottom of second component 20, then drive second component 20 to slide relative to first component 10 and plug-in portion 12, to make at least a part of plug-in portion 12 cooperate from below to above and insert into the installation slot 201 of second component 20.When the end of installation slot 201 abuts to the end of the end of plug-in portion 12 away from the support portion 11, and / or the lower surface of second component 20 abuts to the support portion 11, second component 20 and first component 10 stop relative motion, thereby connecting first component 10 and second component 20.When second component 20 bears from above to below load, the from above to below load of second component 20 acts on the support portion 11, and / or acts on the end of the end of plug-in portion 12 away from the support portion 11;The end of the end of plug-in portion 12 away from the support portion 11 is formed with at least one protruding portion 13, and / or the support portion 11 is formed with at least one protruding portion 13 and is inserted from below to above into second component 20 under the action of from above to below load, thereby improving the connection stability of first component 10 and second component 20, especially improving the connection stability of first component 10 and second component 20 in horizontal direction.

[0050] After the first component 10 and the second component 20 are installed, when the second component 20 is subjected to an external force, it may cause the second component 20 to undergo horizontal displacement relative to the first component 10. Alternatively, if there are processing errors in the manufacturing process of the second component 20, such as the size of the mounting groove 201 being larger than that of the insertion part 12, after the first component 10 and the second component 20 are connected, there will be a gap between the insertion part 12 and the mounting groove 201, and the second component 20 will undergo horizontal displacement relative to the first component 10 when subjected to a horizontal external force. In this embodiment, at least a portion of the protrusion 13 is inserted into the second component 20, thereby greatly increasing the friction between the connector 1 and the second component 20, reducing the horizontal displacement of the second component 20 relative to the connector 1 under the action of a horizontal external force, and improving the connection stability of the first component 10 and the second component 20. It should be particularly noted that when the upward load on the second component 20 increases, the greater the depth of the protrusion 13 inserted into the second component 20 from bottom to top, the greater the friction between the connector 1 and the second component 20, thereby further improving the connection stability of the first component 10 and the second component 20.

[0051] In some embodiments, the protrusion 13 extends in the vertical direction, and the cross-sectional area of ​​the protrusion 13 gradually decreases from bottom to top. By setting the protrusion 13 to extend in the vertical direction and the cross-sectional area of ​​the protrusion 13 gradually decreases from bottom to top, the top of the protrusion 13 is sharp, so that the protrusion 13 can be smoothly inserted into the second component 20 during the sliding process of the second component 20 relative to the first component 10 and the insertion part 12, thereby improving the connection stability of the first component 10 and the second component 20.

[0052] In some embodiments, at least two protrusions 13 are formed at the end of the insertion portion 12 away from the support portion 11. Furthermore, this embodiment does not limit the number or positional relationship of the protrusions 13, such as... Figures 1-8 As shown, for example, at least one protrusion 13 is formed at the end of the insertion portion 12 away from the support portion 11, or at least one protrusion 13 is formed on the support portion 11, or at least one protrusion 13 is formed simultaneously at the end of the insertion portion 12 away from the support portion 11 and on the support portion 11. During the installation process where the second member 20 slides relative to the first member 10 and the insertion portion 12, the protrusions 13 are all inserted into the second member 20, thereby increasing the frictional force between the protrusions 13 and the second member 20 in the horizontal direction and improving the connection stability between the first member 10 and the second member 20. In some embodiments, the connector 1 in this embodiment can be a one-piece molded part, or it can be a combination or combination of accessories made of different materials. For example, metal, hard plastic, or other materials and combinations thereof can be selected, as long as the hardness of the protrusion 13 is greater than the hardness of the second member 20, allowing it to be inserted into the second member 20.

[0053] In some embodiments, the protrusion 13 is a pyramid. The specific structure or shape of the protrusion 13 is not limited in the present embodiment, and can be designed adaptively according to actual use.

[0054] Further, the protrusion 13 is provided in the shape of a regular cone or pyramid. By providing the protrusion 13 in the shape of a regular cone or pyramid, the efficiency of manufacturing the connecting piece 1 can be improved, and the specific structure can be designed adaptively according to actual use.

[0055] In some embodiments, as shown in FIG. 1, the insertion portion 12 is provided with a through hole 14 for the fastener 2 to pass through, and the insertion portion 12 is detachably installed on the first member 10 by the fastener 2. The through hole 14 is in the shape of a circle or an ellipse or a waist circle. Figures 3-12 Figures 4-8 In particular, as shown in FIG. 1, when the through hole 14 is in the shape of an ellipse or a waist circle, the fastener 2 can be adjusted in position laterally in the through hole 14, that is, the connecting piece body can be adjusted in position laterally relative to the first member 10, so that the lateral position of the connecting piece body is fine-tuned during the sliding process of the second member 20 relative to the first member 10 and the insertion portion 12 to ensure that at least a part of the insertion portion 12 is smoothly inserted into the installation groove 201 of the second member 20 from bottom to top, thereby improving the convenience of assembly.

[0056] In some embodiments, the supporting portion 11 abuts against the lower surface of the second member 20. That is, during the assembly process, when the second member 20 is driven to slide relative to the first member 10 and the insertion portion 12, at least a part of the insertion portion 12 is cooperatively inserted into the installation groove 201 of the second member 20 from bottom to top, and the end of the installation groove 201 abuts against the end of the insertion portion 12 away from the supporting portion 11, the lower surface of the second member 20 abuts against the supporting portion 11, the relative movement between the second member 20 and the first member 10 is stopped, and the first member 10 and the second member 20 are connected. When the second member 20 bears a load from top to bottom, a part of the load from top to bottom of the second member 20 acts on the supporting portion 11, and another part of the load from top to bottom of the second member 20 acts on the insertion portion 12, so that the load from top to bottom of the second member 20 is not entirely loaded on the supporting portion 11 or the insertion portion 12 alone, thereby preventing the load from being too high and causing damage to the structure of the connecting piece body and failure, and further improving the load bearing capacity of the second member 20 from top to bottom.
