Description

Technical Field

[0001] The present invention relates to a connection component, a connection system and an installation tool thereof, which are used for connecting a first component and a second component, and are particularly used for connecting furniture components. Background Art

[0002] At present, with the continuous improvement of people's aesthetic concepts, invisible connectors are gradually adopted between two furniture panels or two metal components to achieve invisible connection, so as to improve the aesthetics of furniture or equipment. Among them, plate connectors such as two-in-one connectors, three-in-one connectors or four-in-one connectors are widely used in the connection between two furniture panels. However, the hole diameter for the main body of the eccentric wheel or the four-in-one connector to be inserted into the plate using the existing plate connectors is relatively large (usually greater than or equal to 10 mm), and users can easily observe the main body of the eccentric wheel or the four-in-one connector through the larger hole diameter, resulting in a reduction in the invisibility of the plate connector and affecting the aesthetics of the furniture.

[0003] For this reason, Chinese Patent Publication No. CN114278653A discloses "A Connection Component, a Connection System and an Installation Method". When this connection component is used, first install the third connector on the first connector, then insert the first connector from one side of the plate into the installation channel of the first component, so that the first connection hole is communicated with the first installation hole of the first component. Finally, use tools such as a screwdriver or a hex wrench to pass through the first installation hole to drive the threaded fastener and the connecting rod to be locked with each other, thus completing the invisible connection between the first component and the second component. Since the third connector does not need to be installed into the plate from the first installation hole, the diameter of the first installation hole only needs to be large enough for tools such as a screwdriver to pass through, greatly reducing the diameter of the first installation hole, thereby improving the invisibility of the eccentric wheel on the plate. However, this connection component is fastened inside the plate by a fastening reverse thread. During the installation process, it is necessary to repeatedly adjust the position of the first connector to make the third connector communicate with the first installation hole of the first component, resulting in low installation efficiency. And when it is necessary to remove the first connector from inside the plate, it is necessary to damage the plate before the reinforcement can be removed, with high operation difficulty and low efficiency, and it is not conducive to the aesthetics or recycling of the plate.

[0004] For this reason, Chinese Patent Publication No. CN217633277U discloses "A Connection Component and a Connection System". The connection component is provided with an additional plug. During use, the eccentric wheel is pre-installed on the reinforcement member first, and then an installation tool is used in cooperation with the plug to control the insertion of the reinforcement member into the installation channel of the first member. The eccentric wheel is inserted into the installation channel of the first member from one side of the plate member along with the reinforcement member. Under the action of the installation tool, after the reinforcement member is installed in the installation channel, the eccentric wheel can communicate with the first installation hole of the first member, improving the installation convenience. Subsequently, by rotating the plug, the plug drives the elastic part to expand outward to fix the reinforcement member in the installation channel. Finally, tools such as a screwdriver are used to pass through the first installation hole to drive the eccentric wheel and the connecting rod to be locked with each other, thus completing the invisible connection between the first member and the second member. The connection component uses the plug to adjust the expansion and contraction of the elastic part, enabling the reinforcement member to be removed without damaging the plate member when it needs to be removed from the inside of the plate member, and being able to better correct the reinforcement member during the installation process of the reinforcement member, improving the installation quality. However, the reinforcement member and the plug can move relative to each other. During the process of the installation tool driving the reinforcement member into the installation channel of the first member, there is a risk that the reinforcement member rotates relative to the plug, resulting in a deviation in the position of the eccentric wheel and the first installation hole of the first member when the reinforcement member is inserted into the interior of the installation channel, and the need to re-adjust the position of the reinforcement member, affecting the installation efficiency of the connection component. In addition, during the rotation of the plug, the reinforcement member is also prone to rotate with the plug, causing a deviation in the position of the eccentric wheel and the first installation hole of the first member, which will also affect the installation efficiency of the connection component.

[0005] In addition, when an electrical appliance is installed at the top or bottom of the first member of the furniture, it is usually necessary to process an embedding groove at the edge position or the middle position at the top or bottom of the first member. The embedding groove is used to embed a light strip or allow wires arranged in the embedding groove (the wires can be connected to the light strip or the electrical appliance) to achieve an aesthetic effect. However, when an embedding groove is processed at the top or bottom of the first member with a relatively thin thickness, the embedding groove further reduces the thickness of the edge position of the first member, resulting in damage to the part of the first member with the embedding groove or the exposure of the connecting piece when the connecting piece is inserted into the installation channel of the first member, reducing the aesthetics; or, when an embedding groove is processed after the connecting piece is inserted into the first member, it will damage the opening end of the connecting piece close to the connecting channel. For this reason, Chinese Patent Publication No. CN219220968U discloses "A Connecting Piece, a Connection Component and a Connection System". The connection component is provided with an avoidance recess on the connecting piece assembly, enabling the wire to pass through the avoidance recess, thereby making the connection component suitable for thin plates. However, the connection component also has problems such as the need to repeatedly adjust the position of the connecting piece during the installation process, resulting in low installation efficiency, and the need to damage the plate member when the connecting piece is removed. Summary of the Invention

[0006] In order to solve the technical problem in the prior art that the connecting component cannot have both high installation efficiency and be suitable for being applied to the thin plate of the lighting wire, the present invention provides a connecting component for connecting a first component and a second component. The first component is provided with an installation channel and a first installation hole communicated with the installation channel, and includes:

[0007] A first connecting piece, a first connecting channel is formed at the front end of the first connecting piece, an installation space communicated with the first connecting channel is formed on the outer side wall of the first connecting piece, at least two deformation gaps are formed on the side wall of the first connecting channel, the deformation gaps are communicated to the front end of the first connecting piece, and at least two of the deformation gaps are respectively located on the upper side wall and the lower side wall of the first connecting channel;

[0008] The deformation gap is used to make at least one elastic part formed on a part of the side wall of the first connecting channel, and fastening protrusions are formed on the outer side wall of the elastic part; and / or, the first component is provided with an embedding groove, and at least a part of at least two of the deformation gaps located on the upper side wall and the lower side wall of the first connecting channel is used to be the same as at least a part of the space of the embedding groove so that the power wire can be buried in the space;

[0009] A plug-in, a plug-in channel penetrating through both ends of the plug-in is formed on the plug-in, at least a part of the plug-in is used to cooperate with an external tool to drive the plug-in to translate and / or rotate in the first connecting channel so that the plug-in can be switched between a release position and a locking position; when the plug-in is switched from the release position to the locking position, the plug-in drives at least a part of the elastic part to elastically deform and open outwards so that the first connecting piece is fixedly installed in the installation channel;

[0010] A second connecting piece, a connecting groove is formed at one end of the second connecting piece, a second installation part is provided at the other end of the second connecting piece, the second installation part is used to connect the second component, and the end of the second connecting piece forming the connecting groove penetrates through the plug-in channel and at least a part of the connecting groove is placed at a position where the first connecting channel is communicated with the installation space;

[0011] Further, a threaded fastener is included. An external thread structure is provided on the outer peripheral side wall of the threaded fastener. The threaded fastener is threadedly connected in the installation space, and the threaded fastener can move in the installation space so that one end of the threaded fastener is inserted into the connection groove; alternatively, a third connecting member and a threaded fastener are further included. A third connection channel is formed on the outer side wall of the third connecting member, and a third connection hole communicating with the third connection channel is formed at one end of the third connecting member. The third connecting member is inserted into the installation space and the third connection channel is communicated with the first connection channel. One end of the second connecting member forming the connection groove penetrates through the insertion channel and at least a part of the connection groove is placed at a position where the third connection channel communicates with the third connection hole. An external thread structure is provided on the outer peripheral side wall of the threaded fastener. The threaded fastener is threadedly connected in the third connection hole, and the threaded fastener can move in the third connection hole so that one end of the threaded fastener is inserted into the connection groove; alternatively, a fourth connecting member is further included. The fourth connecting member is arranged in the installation space. The fourth connecting member can rotate in a rotational direction between a release position and a locking position. A slot is formed on the side wall of the fourth connecting member, and at least one inner side wall of the slot is provided with a clamping arm. When the fourth connecting member is in the release position, one end of the second connecting member is inserted into the slot from the opening of the slot. When the fourth connecting member is in the locking position, the clamping arm is inserted into the connection groove to restrict the second connecting member from being pulled out of the slot;

[0012] At least one bump structure, and / or a convex block structure, and / or a rib structure is provided on the outer surface of the side wall of the first connecting member. When the plug is switched between the loosening position and the locking position, the bump structure, and / or the convex block structure, and / or the rib structure can restrict the first connecting member from rotating relative to the installation channel.

[0013] Compared with the prior art, a connection assembly of the present invention has the beneficial effects that: at least one bump structure and / or a convex block structure and / or a rib structure is additionally provided on the outer surface of the side wall of the first connecting member of the present invention. Further, after the first connecting member is inserted into the installation channel, the bump and / or the convex block and / or the rib can tightly abut against the wall surface of the installation channel, increasing the frictional resistance between the first connecting member and the first component, and restricting the rotation of the first connecting member relative to the first component to the greatest extent. When the plug is rotated and adjusted, the first connecting member does not rotate relative to the installation channel or rotates by a relatively small angle in the installation channel, ensuring that after the plug is rotated and adjusted, the threaded fastener or the fourth connecting member can still be accurately aligned with the first installation hole, without readjusting the first connecting member again, reducing unnecessary operations, and thereby improving the installation efficiency.

[0014] In addition, based on the premise that the first connecting member does not generate relative rotation or generates a relatively small angle of relative rotation within the installation channel:

[0015] First, at least two deformation gaps formed at the upper and lower ends can enable the elastic part to expand to the left and right when the plug-in member switches from the loosening position to the locking position, ensuring that the first member will not risk bulging along the longitudinal direction, so as to be more suitable for thinner plates.

[0016] Second, at least two deformation gaps formed at the upper and lower ends can directly use at least a part of the deformation gaps as the avoidance space for the wire, so that the wire and / or the light strip can better hide in the embedding groove by using the deformation gaps, making the connection assembly applicable to the thin plate with wiring.

[0017] Third, at least one of at least two deformation gaps formed at the upper and lower ends can cooperate with the installation tool to position the first connecting member during the installation process.

[0018] In some embodiments, the first connecting member includes a first connecting portion and a first mounting portion, and one end of the first connecting portion and one end of the first mounting portion can be fixedly or detachably connected; the first connecting channel penetrates through the first connecting portion and extends into the first mounting portion, and the installation space is formed on the outer side wall of the first mounting portion. Separately manufacturing the first connecting portion and the first mounting portion can reduce the product forming difficulty, and thus improve the yield rate of the first connecting member.

[0019] In some embodiments, the rib structure is arranged along the length direction of the first connecting member. The length direction of the first connecting member is perpendicular to the possible rotation direction during the installation process of the first connecting member into the installation channel. Arranging the rib structure along the length direction of the first connecting member can limit the rotation of the first connecting member in the installation channel to the greatest extent.

[0020] In some embodiments, there are two rib structures, and the two rib structures are respectively arranged on the left and right sides of the end of the first connecting member. The increase in the number of rib structures can correspondingly increase the frictional resistance between the first connecting member and the first member, thereby restricting the rotation of the first connecting member in the installation channel.

[0021] In some embodiments, the deformation gap includes an avoidance concave portion and a constricted portion. The avoidance concave portion is the same as at least a part of the space of the embedding groove, and the constricted portion is located in the installation channel. The structure of the avoidance concave portion corresponds to the structure of the embedding groove for the wire to pass through, improving the aesthetics of the furniture. The significance of setting the constricted portion is to increase the area of the elastic part, thereby increasing the frictional force between the first connecting member and the wall surface of the installation channel and improving the connection stability between the first connecting member and the first member.

[0022] To solve the technical problem of low installation efficiency of connection components in the prior art, the present invention also provides an installation tool for installing the connection components, including:

[0023] A first side portion, a second side portion, and a bottom portion. The first side portion and the second side portion are perpendicularly arranged on both sides of the bottom portion, and the first side portion and the second side portion are parallel to each other;

[0024] At least one of the deformation gaps communicates with the end of the first connecting member;

[0025] An installation protrusion is provided on the bottom portion. The installation protrusion is correspondingly arranged with at least one of the deformation gaps communicating with the end of the first connecting member, so that when the first connecting member is installed in the installation channel through the installation tool, the first installation hole corresponds to the installation space in position.

[0026] Compared with the prior art, the beneficial effect of an installation tool of the present invention is that: the installation tool of the present invention directly cooperates with the deformation gap of the first connecting member through the installation protrusion. Thus, when the first side portion and the second side portion are respectively in contact with the top surface and the bottom surface of the first member, it can be ensured that the installation space of the first connecting member and the first installation hole are in the same vertical plane. When the first connecting member is installed in place, the installation space of the first connecting member can be accurately aligned with the first installation hole, without readjusting the first connecting member again, reducing unnecessary operations, thereby improving the installation efficiency.

[0027] In some embodiments, a positioning portion is provided on the bottom portion. The positioning portion cooperates with at least a part of the plug or at least a part of the first connecting member to make the installation protrusion snap into the deformation gap communicating with the end of the first connecting member. By the positioning portion, the contact part between the installation tool and the first connecting member is increased, thereby improving the cooperation stability between the installation tool and the first connecting member.

[0028] In some embodiments, the positioning portion includes a positioning post. The positioning post cooperates with the insertion channel to make the installation protrusion snap into the deformation gap communicating with the end of the first connecting member.

[0029] In some embodiments, the positioning portion includes a positioning recess. The positioning recess cooperates with the end of the plug to make the installation protrusion snap into the deformation gap communicating with the end of the first connecting member.

[0030] To solve the technical problem of low installation efficiency of connection components in the prior art, the present invention also provides a connection system, including a first member, a second member, and the connection components;

[0031] The first member is provided with an installation channel and a first installation hole communicating with the installation channel;

[0032] The first connecting member is inserted into the installation channel, and the installation space corresponds to the position of the first installation hole;

[0033] The plug is switched from the release position to the locking position so that the first connecting member is fixedly installed in the installation channel;

[0034] One side of the second member is provided with a second installation hole, and one end of the second connecting member away from the connecting groove is installed in the second installation hole;

[0035] Wherein, one end of the second connecting member formed with the connecting groove penetrates through the insertion channel and at least a part of the connecting groove is placed at a position where the first connecting channel communicates with the installation space, and the threaded fastener is inserted into the installation space and moves until one end of the threaded fastener is inserted into the connecting groove; or, the third connecting member is installed in the installation space and the third connecting channel communicates with the first connecting channel, and one end of the second connecting member formed with the connecting groove penetrates through the insertion channel and at least a part of the connecting groove is placed at a position where the third connecting channel communicates with the third connecting hole; the threaded fastener is inserted into the third connecting hole through the first installation hole and moves until one end of the threaded fastener is inserted into the connecting groove; or, the fourth connecting member is installed in the installation space, one end of the second connecting member formed with the connecting groove penetrates through the first connecting channel and a part of the connecting groove moves into the slot, and the fourth connecting member rotates in the installation space until the clamping arm is inserted into the connecting groove.

[0036] Compared with the prior art, the beneficial effect of a connection system of the present invention is that after the first connecting member is inserted into the interior of the installation channel, the bumps and / or protrusions and / or ribs can tightly abut against the wall surface of the installation channel, increasing the frictional resistance between the first connecting member and the first member, and restricting the rotation of the first connecting member relative to the first member to the greatest extent. When the plug is rotated and adjusted, the first connecting member and the installation channel do not generate relative rotation or the relative rotation angle is small, ensuring that after the plug is rotated and adjusted, the threaded fastener or the fourth connecting member can still be accurately aligned with the first installation hole, without readjusting the first connecting member again, reducing unnecessary operations, thereby improving the installation efficiency.

[0037] In addition, at least two deformation gaps formed at the upper and lower ends can cause the elastic part to open to the left and right sides when the plug is switched from the release position to the locking position, which can ensure that the first member will not risk bulging along the longitudinal direction, making it more suitable for thinner plates.

[0038] In addition, when the connection component is applied to the thin plate of the cloth wire, the wire and / or the light strip can pass through the deformation gap, and the aesthetics is better. Brief Description of the Drawings

[0076] Embodiment 1

[0077] As Figure 1-8 As shown in FIGS. 18 - 21, an embodiment of the present invention provides a connection assembly for connecting a first member 10 and a second member 20. The first member 10 is provided with an installation channel 101 and a first installation hole 102 communicating with the installation channel 101. The connection assembly includes a first connector 1, a plug 4, a second connector 2, and a threaded fastener 5. A first connection channel 11 is formed at the front end of the first connector 1. An installation space 12 communicating with the first connection channel 11 is formed on the outer sidewall of the first connector 1. At least two deformation gaps 13 are formed on the sidewall of the first connection channel 11, and at least two of the deformation gaps 13 are respectively located on the upper sidewall and the lower sidewall of the first connection channel 11. The deformation gaps 13 can be used to form at least one elastic portion 14 on a part of the sidewall of the first connection channel 11, and a fastening protrusion 15 is formed on the outer sidewall of the elastic portion 14. The plug 4 is formed with a plugging channel 41 penetrating through both ends of the plug 4. At least a part of the plug 4 is used to cooperate with an external tool to drive the plug 4 to translate and / or rotate in the first connection channel 11, so that the plug 4 can be switched between a release position and a locking position; when the plug 4 is switched from the release position to the locking position, the plug 4 drives at least a part of the elastic portion 14 to elastically deform and expand outward, so that the first connector 1 is fixedly installed in the installation channel 101. One end of the second connector 2 is formed with a connection groove 21, and the other end of the second connector 2 is provided with a second installation portion 22 for connecting the second member 20. The end of the second connector 2 formed with the connection groove 21 penetrates through the plugging channel 41 and at least a part of the connection groove 21 is placed at a position where the first connection channel 11 communicates with the installation space 12. The outer peripheral sidewall of the threaded fastener 5 is provided with an external thread structure, and the threaded fastener 5 is threadedly connected in the installation space 12. The threaded fastener 5 can move in the installation space 12 so that one end of the threaded fastener 5 is inserted into the connection groove 21.

[0078] Among them, as Figures 11-17As shown, at least one bump structure, and / or a protrusion structure, and / or a rib structure 6 is further provided on the outer surface of the side wall of the first connecting member 1. When the plug-in member 4 switches between the release position and the locking position, the bump structure, and / or the protrusion structure, and / or the rib structure can limit the relative rotation of the first connecting member 1 with respect to the installation channel 101. The present invention does not limit the number, position, shape or size of the bump structure, and / or the protrusion structure, and / or the rib structure 6. The bump structure, and / or the protrusion structure, and / or the rib structure 6 can be provided on the fastening protrusion 15 on the outer side wall of the first connecting member 1, or can be provided at one end of the outer side wall of the first connecting member 1 close to the installation space 12.

[0079] In practical applications, after the first connecting member 1 is inserted into the installation channel 101 of the first member 10, the bump or protrusion or rib abuts against the inner wall of the installation channel 101, and one end of the plug-in member 4 is inserted into the first connection channel 11. When at least a part of the plug-in member 4 is used to cooperate with an external tool to drive the plug-in member 4 to translate and / or rotate in the first connection channel 11, the plug-in member 4 switches from the release position to the locking position, and at least a part of the elastic portion 14 of the first connecting member 1 undergoes elastic deformation and expands outwards, so that the fastening protrusion 15 on the outer side wall of the elastic portion 14 abuts against the inner side wall of the installation channel 101, increasing the sliding friction force of the first connecting member 1 in the installation channel 101, so that it is difficult for the first connecting member 1 to slide in the installation channel 101, thereby fixing the first connecting member 1 in the installation channel 101. During the above installation process, the rotational friction force between the first connecting member 1 and the inner wall of the installation channel 101 is increased by the bump or protrusion or rib, thereby restricting the relative rotation of the first connecting member 1 with respect to the first member 10. In this way, at least a part of the plug-in member 4 is used to cooperate with an external tool to drive the plug-in member 4 to translate and / or rotate in the first connection channel 11. When the plug-in member 4 switches from the release position to the locking position, there is no relative rotation or a relatively small relative rotation angle between the first connecting member 1 and the installation channel 101, ensuring that the installation space 12 on the first connecting member 1 is communicated with the first installation hole 102 on the first member 10 after installation, reducing the trouble of repeatedly adjusting the angle of the first connecting member 1 after installation, and further improving the installation efficiency.

[0080] In addition, when it is necessary to remove the first connecting member 1 from the installation channel 101, the plug-in member 4 is switched from the locking position to the release position, so that the elastically deformed part of the elastic portion 14 at the locking position returns to its original state, and the fastening protrusion 15 on the outer side wall of the elastic portion 14 no longer abuts against the inner side wall of the installation channel 101, and the friction force between the outer side wall of the first connecting member 1 and the installation channel 101 returns to a smaller value, so that the first connecting member 1 can be pulled out of the installation channel 101. The installation and disassembly efficiency is high, the operation is convenient, and at the same time, the damage to the first member 10 is reduced, ensuring the integrity and beauty of the member and the plate, and being beneficial to the repeated recycling of the plate.

[0081] In some embodiments, as Figures 14-17 shown, the rib structure 6 is arranged along the length direction of the first connecting member 1. The length direction of the first connecting member 1 is perpendicular to the rotation direction that may occur during the installation process of the first connecting member 1 onto the installation channel 101, which can further reduce the process of repeatedly adjusting the first connecting member 1 after installation. In some embodiments, there are two rib structures 6, and the two rib structures 6 are respectively arranged on the left and right sides of the end of the first connecting member 1. Such an arrangement can make the acting force of the rib structure 6 on the first member 10 along the length direction of the first member 10 when the first connecting member 1 abuts against the installation channel 101 during the installation process, reduce the damage of the first member 10 during the installation process, and further improve the disassembly and assembly times and service life of the connection assembly.

[0082] In some embodiments, the deformation gap 13 communicates with the end of the first connecting member 1, which can improve the deformation ability of the part of the elastic part 14 that undergoes elastic deformation when the locking position is reached, make the first connecting member 1 have a stronger tensile load-bearing capacity in the installation channel 101, and thus improve the connection stability between the first connecting member 1 and the first member 10. The present invention does not limit the number, position, shape or size of the deformation gap 13, and the number of the deformation gaps 13 can be one or more. In addition, at least one deformation gap 13 communicates with the end of the first connecting member 1, and through this deformation gap 13, positioning can be achieved, so that the position of the installation space 12 corresponds to the position of the first installation hole 102 during the installation process, and the installation efficiency of the connection assembly can be improved.

[0083] In some embodiments, the installation space 12 is arranged at the top of the outer side wall of the first connecting member 1. When there are two deformation gaps 13, the two deformation gaps 13 are respectively arranged at the top and bottom of the end of the first connecting member 1. The deformation gap 13 can be used to indicate the orientation of the first connecting member 1 in the first member 10 during the installation process, so that the installation space 12 communicates with the first installation hole 102, thereby reducing the trouble of repeatedly adjusting the angle of the first connecting member 1 after it is inserted into the first member 10 and improving the installation efficiency.

[0084] Further, when the two deformation gaps 13 are respectively provided at the top and bottom of the end of the first connecting member 1, elastic portions 14 are respectively formed on the left and right side walls of the first connecting channel 11. When the first member 10 is a shelf of a cabinet, the thickness dimension of the first member 10 is usually small. After the installation channel 101 is provided on the side wall of the first member 10, the thickness dimension of the first member 10 in the up and down directions at the position of the installation channel 101 is further reduced. When the first connecting member 1 is installed into the installation channel 101, in order to prevent the elastic portion 14 from elastically deforming and damaging the top or bottom of the first member 10, the deformation direction of the elastic portion 14 is provided in the length direction of the plate of the first member 10. The left and right side walls of the end of the first connecting member 1 form the elastic portion 14. During the installation and disassembly process, the upper and lower parts of the first member 10 at the position of the installation channel 101 will not deform, thus ensuring that the first member 10 is not damaged by the elastic portion 14, and improving the disassembly and assembly times and service life of the connecting component.

[0085] Further, the connecting component involved in the present invention is applicable to the connection between any two plate members such as wooden boards and metal plates. Among them, when an electrical appliance is installed on the top or bottom of the first member 10, a structure for accommodating lamp wires needs to be provided on the top or bottom of the first member 10 to ensure the beauty of the furniture. For this reason, in the first embodiment, as Figures 29-31 shown, the first member 10 is provided with an embedding groove 103. At least a part of at least two deformation gaps 13 located on the upper and lower side walls of the first connecting channel 11 is used to be the same as at least a part of the space of the embedding groove 103 so that the wire can be buried in the space. On the basis of restricting the first connecting member 1 in the installation channel 101 by using bumps or protrusions or ribs, at least two deformation gaps 13 formed at the upper and lower ends can directly use at least a part of the deformation gap 13 as an avoidance space for the wire, so that the wire and / or the light strip can be better hidden in the embedding groove 103 by using the deformation gap 13, making the connecting component more beautiful when applied to a thin plate with wiring; in addition, at least two deformation gaps 13 formed at the upper and lower ends can make the elastic portion 14 open to the left and right sides when the plug 4 switches from the loosening position to the locking position, ensuring that the first member 10 will not have the risk of board swelling in the longitudinal direction, so as to be more suitable for thinner plates; furthermore, at least one of at least two deformation gaps 13 formed at the upper and lower ends can cooperate with the installation tool 7 to position the first connecting member 1 during the installation process.

[0086] In some embodiments, as Figures 29-30As shown, the deformation gap 13 includes an avoidance recess 131 and a shrinking portion 132. The avoidance recess 131 has at least a portion of the same space as the embedding groove 103, and the shrinking portion 132 is located in the installation channel 101. The avoidance recess 131 is arranged close to the opening of the first connection channel 11, and the structure of the avoidance recess 131 corresponds to the structure of the embedding groove 103, so as to allow the power line to pass through and improve the aesthetics of the furniture. The setting of the shrinking portion 104 is intended to reduce the space occupied by the deformation gap 13 and increase the area of ​​the elastic portion 14, thereby increasing the friction between the first connector 1 and the wall of the installation channel 101 and improving the connection stability between the first connector 1 and the first member 10. The depth of the avoidance recess 131 can be designed according to the groove depth adaptability of the embedding groove 103, for example, the depth of the avoidance recess 131 is 0.1-1.5 mm, and the width of the avoidance recess 131 is the same or nearly the same as the groove width of the embedding groove 103, for example, the width of the avoidance recess 131 is 0.1-3.0 mm, so that after the first connector 1 is inserted into the installation channel 101, the position of the avoidance recess 131 just moves to the position of the embedding groove 103. Among them, the avoidance recess 131 can be formed on the top of the first connector 1, or the avoidance recess 131 can be formed on the bottom of the first connector 1, or the avoidance recess 131 can be formed on the top and bottom of the first connector respectively, which is specifically set according to the position adaptability of the embedding groove 103 on the first component 10. The avoidance recess 131 is located at one end of the first connector 1 so that the end of the first connector 1 is notched. When the first component 10 is connected to the second component 20 , the light strip or the wire is inserted into the embedding groove 103 , and a portion of the light strip or the wire crosses over the avoiding recess 131 .

[0087] In this embodiment 1, if Figure 1-8 As shown, a second mounting hole 201 is formed on one side of the second component 20, a connecting groove 21 is formed on one end of the second connecting member 2, and a second mounting portion 22 is formed on the other end of the second connecting member 2. The second mounting portion 22 is used to connect the second component 20. An external thread portion is formed on the outer wall of the second mounting portion 22. The diameter of the second mounting hole 201 is smaller than the outer contour diameter of the external thread portion of the second mounting portion 22. The external thread portion of the second mounting portion 22 is self-tapping and screwed into the second mounting hole 201. In addition, as Figure 9 As shown, the second mounting portion 22 may also include an expansion nut 23. The structure of the expansion nut 23 is exactly the same as the structure of the expansion nut 23 of the three-in-one connector or the four-in-one connector in the prior art, and the structure of the expansion nut 23 is omitted here. The diameter of the second mounting hole 201 is larger than the diameter of the outer contour of the expansion nut 23. Then, the second connector 2 and the expansion nut 23 are installed in the second mounting hole 201. The second connector 2 is rotated to drive the outer peripheral wall of the expansion nut 23 to gradually expand radially outward and abut against the inner wall of the second mounting hole 201, so that the second connector 2 is firmly connected to the second component 20 through the expansion nut 23.

[0088] In some embodiments, such as Figures 10-12 shown, the first connecting member 1 includes a first connecting portion 16 and a first mounting portion 17. One end of the first connecting portion 16 and one end of the first mounting portion 17 can be fixedly or detachably connected. For example, the first connecting portion 16 and the first mounting portion 17 are connected by snap connection or by inserting posts into each other. It only needs to be ensured that during the connection process of the first member 10 and the second member 20, there is no relative displacement and relative rotation between the first connecting portion 16 and the second mounting portion 22. The first connecting channel 11 penetrates through the first connecting portion 16 and extends into the first mounting portion 17, and the mounting space 12 is formed on the outer sidewall of the first mounting portion 17.

[0089] The threaded fastener 5 in the first embodiment is the threaded fastener 5 in a four-in-one connecting member in the prior art, such as a screw or a bolt or a threaded rod, etc., and preferably a countersunk screw or bolt. The material of the threaded fastener 5 can be metal or hard plastic, etc., preferably a metal material, having a relatively large hardness to prevent the first connecting member 1 from causing damage to the threaded fastener 5 after being subjected to a relatively large tensile force, resulting in the end of the second connecting member 2 having the connecting groove 21 being easily pulled out from the first connecting channel 11.

[0090] The threaded fastening is achieved by self-tapping connection with the inner sidewall of the mounting space 12. Specifically, the threaded fastener 5 is a screw, and the hardness of the threaded fastener 5 is greater than the hardness of the first connecting member 1. For example, the threaded fastener 5 is made of iron or stainless steel or an alloy with a relatively large hardness, etc., and the material of the first connecting member 1 is hard plastic or an aluminum alloy or zinc alloy with a relatively low hardness. At the same time, the diameter dimension of the outer sidewall contour of the threaded fastener 5 is greater than the diameter dimension of the mounting space 12. When the threaded fastener 5 is inserted into the mounting space 12, an external force is used to drive the threaded fastener 5 to rotate in the mounting space 12. The external thread structure on the threaded fastener 5 self-taps to form an internal thread structure on the inner sidewall of the mounting space 12. The threaded fastener 5 bites tightly with the inner sidewall of the mounting space 12 so that the threaded fastener 5 is in a stationary state in the mounting space 12. The second connecting member 2 is inserted into the threaded fastener 5 through the connecting groove 21 to limit the end of the second connecting member 2 having the connecting groove 21 from being pulled out of the mounting space 12, thereby firmly connecting the first member 10 and the second member 20 to each other.

[0091] In other embodiments, such as Figures 10-12As shown, thread teeth are formed on the inner wall of the installation space 12, and the threaded fastener 5 is threadedly connected by cooperating with the thread teeth so that the threaded fastener 5 is threadedly connected within the installation space 12. At this time, the threaded fastener 5 is, for example, a screw or a bolt or a threaded rod. By driving the threaded fastener 5 to cooperate and engage with the thread teeth on the inner wall of the installation space 12, the threaded fastener 5 slides while rotating within the installation space 12, so that one end of the threaded fastener 5 can be inserted into the connection groove 21. The second connecting member 2 is inserted in cooperation with the threaded fastener 5 through the connection groove 21 to prevent the end of the second connecting member 2 having the connection groove 21 from being pulled out of the installation space 12, thereby firmly connecting the first member 10 and the second member 20 to each other.

[0092] Based on the above solution, for the connection assembly according to an embodiment of the present invention, the aperture of the installation space 12 can be designed accordingly according to the diameter size of the threaded fastener 5 or the diameter size of the tool for rotating the threaded fastener 5. Since the diameter size of the threaded fastener 5 or the diameter size of the tool for rotating the threaded fastener 5 is small, the aperture of the first installation hole 102 is also small. By reducing the aperture of the first installation hole 102, the invisibility of the connection assembly according to the first embodiment of the present invention inside the first member 10 and the second member 20 is improved, thereby improving the aesthetics of the finished furniture.

[0093] In addition, the threaded fastener 5 according to an embodiment of the present invention can also be pre-installed in the installation space 12 first, so that the aperture of the first installation hole 102 can be so small that only the tool for rotating the threaded fastener 5 can pass through; subsequently, a tool such as a screwdriver is used to pass through the first installation hole 102 and then drive the threaded fastener 5 to move within the installation space 12. In addition, after the first member 10 and the second member 20 are connected by using the connection assembly according to the first embodiment of the present invention, when the first member 10 and the second member 20 are fixedly connected and subjected to a tensile force, the tensile force borne by the first connecting member 1 mainly acts between the fastening reverse teeth and the inner wall of the installation channel 101. Since the engagement area between the fastening reverse teeth and the installation channel 101 is large and the fastening effect is strong, compared with the use of an eccentric wheel for connection in a traditional connecting member, during use, the load is all applied to the connection between the eccentric wheel and the member. In this embodiment, the first connecting member 1 has a stronger ability to bear the tensile load within the installation channel 101, greatly improving the tensile load-bearing capacity between the first member 10 and the second member 20, thereby improving the connection stability between the first member 10 and the second member 20.

[0094] Embodiment Two

[0095] An embodiment two of the present invention provides a connection assembly, as Figure 13As shown in the figure, it includes a first connector 1, a plug-in 4, a second connector 2, a third connector 3 and a threaded fastener 5. A first connection channel 11 is formed at the front end of the first connector 1, and an installation space 12 communicating with the first connection channel 11 is formed on the outer side wall of the first connector 1; at least two deformation gaps 13 are formed on the side wall of the first connection channel 11, the deformation gaps 13 communicate to the front end of the first connector 1, and at least two of the deformation gaps 13 are respectively located on the upper side wall and the lower side wall of the first connection channel 11. The deformation gaps 13 are used to form at least one elastic part 14 on a part of the side wall of the first connection channel 11, and a fastening protrusion 15 is formed on the outer side wall of the elastic part 14; and / or, the first member 10 is provided with an embedding groove 103, and at least a part of at least two deformation gaps 13 located on the upper side wall and the lower side wall of the first connection channel 11 is used to have the same space as at least a part of the embedding groove 103 so that the power line can be buried in the space. The plug-in 4 is formed with a plugging channel 41 penetrating through both ends of the plug-in 4, and at least a part of the plug-in 4 is used to cooperate with an external tool to drive the plug-in 4 to translate and / or rotate in the first connection channel 11 so that the plug-in 4 can be switched between a release position and a locking position; when the plug-in 4 is switched from the release position to the locking position, the plug-in 4 drives at least a part of the elastic part 14 to elastically deform and expand outwards so that the first connector 1 is fixedly installed in the installation channel 101. One end of the second connector 2 is formed with a connection groove 21, and the other end of the second connector 2 is provided with a second installation part 22, and the second installation part 22 is used to connect the second member 20. A third connection channel 31 is formed on the outer side wall of the third connector 3, a third connection hole 32 communicating with the third connection channel 31 is formed at one end of the third connector 3, the third connector 3 is inserted into the installation space 12 and the third connection channel 31 is communicated with the first connection channel 11, and one end of the second connector 2 formed with the connection groove 21 penetrates through the plugging channel 41 and at least a part of the connection groove 21 is placed at a position where the third connection channel 31 is communicated with the third connection hole 32. The outer peripheral side wall of the threaded fastener 5 is provided with an external thread structure, the threaded fastener 5 is threadedly connected in the installation space 12, and the threaded fastener 5 can move in the installation space 12 so that one end of the threaded fastener 5 is inserted into the connection groove 21.

[0096] Wherein, at least one bump structure, and / or a convex block structure, and / or a rib structure 6 is provided on the outer surface of the side wall of the first connector 1. When the plug-in 4 is switched between the release position and the locking position, the bump structure, and / or the convex block structure, and / or the rib structure can limit the rotation of the first connector 1 relative to the installation channel 101.

[0097] The connection relationships among the first connector 1, the second connector 2, the third connector 3, and the threaded fastener 5 of the connection component according to the second embodiment of the present invention are specifically as follows: The third connector 3 is inserted into the installation space 12 so that the third connection channel 31 communicates with the first connection channel 11. One end of the second connector 2 passes through the first connection channel 11 so that at least a part of the connection groove 21 is located at a position where the third connection channel 31 communicates with the third connection hole 32. The threaded fastener 5 is threadedly connected to the third connection hole 32, and the threaded fastener 5 moves in the third connection hole 32 so that one end of the threaded fastener 5 is inserted into the connection groove 21. Among them, the material of the third connector 3 can be a metal material or a hard plastic material. For example, when the third connector 3 is a metal material, an internal thread structure is formed on the inner side wall of the third connection hole 32 by tapping with a tap, and the threaded fastener 5 is threadedly connected to the third connection hole 32 by cooperating with the internal thread structure on the inner side wall of the third connection hole 32.

[0098] Based on the above solution, the third connector 3 in the second embodiment of the present invention can be pre-installed in the installation space 12 first so that the third connection channel 31 communicates with the first connection channel 11, which is more convenient and rapid in operation and improves the installation efficiency of the connection component. At the same time, when the installation space 12 is opened on the first member 10 of the present invention, it is not necessary to design according to the diameter size of the third connector 3 (i.e., the diameter size of the fixed pin in the prior art). It is only necessary to make the aperture of the first installation hole 102 large enough for the threaded fastener 5 to pass through and insert into the third connection hole 32, so as to greatly reduce the aperture of the first installation hole 102 to improve the invisibility of the connection component of the present invention inside the first member 10 and the second member 20, thereby improving the aesthetics of the furniture finished product. In addition, the threaded fastener 5 of the present invention can also be pre-installed in the third connection hole 32 first, so that the aperture of the first installation hole 102 can be so small that only a tool for rotating the threaded fastener 5 can pass through; then a tool such as a screwdriver is used to pass through the first installation hole 102 and drive the threaded fastener 5 to move in the third connection hole 32.

[0099] For the remaining structures of this embodiment, please refer to Embodiment 1 and will not be elaborated here.

[0100] Embodiment 3

[0101] The third embodiment of the present invention provides a connection component, as Figures 29-30As shown, the difference from the first embodiment lies in that the connection component includes a first connecting member 1, a plug-in member 4, a second connecting member 2 and a fourth connecting member 8; a first connecting channel 11 is formed at the front end of the first connecting member 1, and an installation space 12 communicating with the first connecting channel 11 is formed on the outer side wall of the first connecting member 1. At least two deformation gaps 13 are formed on the side wall of the first connecting channel 11, and the deformation gaps 13 communicate with the front end of the first connecting member 1. At least two of the deformation gaps 13 are respectively located on the upper side wall and the lower side wall of the first connecting channel 11. The deformation gaps 13 are used to form at least one elastic portion 14 on a part of the side wall of the first connecting channel 11, and a fastening protrusion 15 is formed on the outer side wall of the elastic portion 14; and / or, the first member 10 is provided with an embedding groove 103, and at least a part of at least two deformation gaps 13 located on the upper side wall and the lower side wall of the first connecting channel 11 is used to be the same as at least a part of the space of the embedding groove 103 so that the power line can be buried in the space. The plug-in member 4 is formed with a plugging channel 41 penetrating through both ends of the plug-in member 4, and at least a part of the plug-in member 4 is used to cooperate with an external tool to drive the plug-in member 4 to translate and / or rotate in the first connecting channel 11 so that the plug-in member 4 can be switched between a release position and a locking position; when the plug-in member 4 is switched from the release position to the locking position, the plug-in member 4 drives at least a part of the elastic portion 14 to elastically deform and expand outwards so that the first connecting member 1 is fixedly installed in the installation channel 101. One end of the second connecting member 2 is formed with a connecting groove 21, and the other end of the second connecting member 2 is provided with a second installation portion 22 for connecting the second member 20. The end of the second connecting member 2 formed with the connecting groove 21 penetrates through the plugging channel 41 and at least a part of the connecting groove 21 is placed at a position where the first connecting channel 11 communicates with the installation space 12.

A slot 81 is formed on the side wall of the fourth connecting member 8, and at least one inner side wall of the slot 81 is provided with a clamping arm 82. When the fourth connecting member 8 is in the release position, one end of the second connecting member 2 is inserted into the slot 81 from the opening of the slot 81. When the fourth connecting member 8 is in the locking position, the clamping arm 82 is inserted into the connecting groove 21 to limit the second connecting member 2 from being pulled out of the slot 81;

[0102] Wherein, at least one bump structure, and / or a convex block structure, and / or a rib structure 6 is provided on the outer surface of the side wall of the first connecting member 1.

[0105] For the remaining structures of this embodiment, please refer to Embodiment 1 and will not be elaborated here.

[0106] Embodiment 4

[0107] The difference between this embodiment and Embodiment 1 is that the threaded fastener 5 is indirectly threadedly connected to the installation space 12. As Figure 22 shown, the connection assembly of the fourth embodiment of the present invention further includes a first metal block 121 provided at the opening of the installation space 12. A first threaded hole 122 communicating with the installation space 12 is opened on the first metal block 121. The threaded fastener 5 is threadedly connected to the installation space 12 by cooperating with the first threaded hole 122. The internal thread structure of the first threaded hole 122 can be formed by tapping with a tap or an internal thread structure integrally formed with the first metal block 121 inside the first threaded hole 122. In this embodiment, there are no restrictions on the shape, cross-sectional shape, size and thickness, and the number of internal thread turns of the first metal block 121, as long as it can ensure that the threaded fastener 5 is firmly and stably installed in the installation space 12 and restricts the end of the second connecting member 2 with the connection groove 21 from being pulled out of the first connection channel 11 after installation.

[0108] Embodiment 5

[0109] The difference between this embodiment and the first embodiment is that the threaded fastener 5 is indirectly threadedly connected to the installation space 12, such as Figure 23 shown, the connection assembly of the fifth embodiment of the present invention further includes a second metal block 123, the second metal block 123 is provided with a second threaded hole 124, a jack 125 communicating with the installation space 12 is provided on the outer side wall of the first connecting member 1, and the second metal block 123 is inserted into the jack 125; the threaded fastener 5 is threadedly connected to the installation space 12 by being threadedly connected with the second threaded hole 124. The internal thread structure of the second threaded hole 124 can be formed by tapping with a tap, or can be an internal thread structure integrally formed with the second metal block 123 inside the second threaded hole 124.

[0110] Embodiment Six

[0111] The difference between this embodiment and the second embodiment is that the outer side wall of the third connecting member 3 has at least one positioning plane or positioning convex point or positioning groove, or the cross-section of the third connecting member 3 is oval or waist-shaped. The shape of the inner side wall of the installation space 12 matches the shape of the outer side wall of the third connecting member 3, that is, one side of the inner side wall of the installation space 12 is flat or grooved or convex-pointed, or oval or waist-shaped. In this way, when the third connecting member 3 is inserted into the installation space 12, the outer side wall of the third connecting member 3 is inserted and connected with the inner side wall of the installation space 12 through shape matching, so that the first connection channel 11 and the third connection channel 31 can be quickly connected, avoiding the trouble of angle adjustment of the third connecting member 3 in the installation space 12, thereby improving the assembly efficiency of the connection assembly in this embodiment.

[0112] In some embodiments, in order to control the switching of the plug 4 between the release position and the locking position, an external tool (such as a columnar body) can be inserted into the insertion channel 41, and the plug 4 can be driven to rotate in the first connection channel 11, so as to adjust the position of the plug 4 in the first connector 1. At least one first operation plane or first operation bump or first operation groove is provided on the inner side wall of the insertion channel 41, so that the external tool can drive the plug 4 to rotate after being inserted into the insertion channel 41. In some other embodiments, the cross-sectional shape of at least a part of the insertion channel 41 is non-circular. For example, a part of the insertion channel 41 near its opening has a non-circular cross-section, and another part of the insertion channel 41 has a circular cross-section; or for another example, the cross-sectional shape of the entire insertion channel 41 is the same and non-circular. Specifically, the external tool in this embodiment can be a columnar body adapted to the cross-sectional shape of the insertion channel 4131. After the external tool is inserted into the insertion channel 41, at least a part of the external tool abuts against the inner side wall of the insertion channel 41, so that the rotating columnar body can drive the plug 4 to rotate in the first connection channel 11. In another embodiment, in order to control the switching of the plug 4 between the release position and the locking position, an external tool (such as a columnar body) can also drive the plug 4 to translate in the first connection channel 11, so that the plug 4 moves from the release position to the locking position; an external tool (such as a hook-shaped member) can drive the plug 4 to translate in the first connection channel 11, so that the plug 4 moves from the locking position to the release position, so as to adjust the position of the plug 4 in the first connector 1. In another embodiment, the cross-sectional shape of at least a part of the insertion channel 41 is the same as the cross-sectional shape of the outer ring of the sleeve. At this time, at least a part of the insertion channel 41 is a sleeve structure of a socket wrench. The socket wrench is a commonly used tool in the art, such as a manual socket wrench of national standard GB T 3390.1-2004, or a manual socket wrench or an electric wrench of other national standards. The cross-section of the insertion channel 41 in the shape of a sleeve is non-circular, including but not limited to triangle or square or hexagon or octagon or ellipse or waist circle or petal shape, etc. The cross-sectional shape of the external tool is adapted to the cross-sectional shape of the insertion channel 41, so that the external tool can drive the plug 4 to move in the first connection channel 11 after being inserted into the insertion channel 41, so as to adjust the position of the plug 4 in the first connection channel 11.

[0113] In some embodiments, the first connecting member 1 is integrally formed in a cylindrical shape to fit into the installation channel 101 formed by drilling, reducing the gap between the first connecting member 1 and the inner sidewall of the installation channel 101 and improving the installation stability of the first connecting member 1 within the installation channel 101. The cross-sectional area of the installation channel 101 is equal to or slightly larger than the cross-sectional area of the first connecting member 1. To adapt to common plates and components in the prior art, the outer diameter of the fastening protrusion 15 on the outer sidewall of the first connecting member 1 can be selected in the range of 8-16 mm. If the outer diameter of the fastening protrusion 15 is greater than 16 mm, it will cause the diameter of the installation channel 101 on the plate to be too large, affecting the strength of the plate and resulting in a larger size of the connection assembly and a decrease in the invisibility performance. If the outer diameter of the fastening protrusion 15 is less than 8 mm, it will cause the size of the connecting member to be too small, insufficient bearing load, and unstable connection between the first member 10 and the second member 20. In some embodiments, the outer diameter of the fastening protrusion 15 can be selected in the range of 10-14 mm. During the actual installation process, the size of the connection assembly can be adjusted according to the thickness of the plate and the load, thereby improving the invisibility and aesthetics while ensuring a stable connection.

[0114] Embodiment Seven

[0115] This embodiment provides an installation tool for installing the connection assembly in the above embodiment, such as Figures 24-28 shown. The installation tool 7 includes a first side portion 71, a second side portion 72, and a bottom portion 73. The first side portion 71 and the second side portion 72 are perpendicularly arranged on both sides of the bottom portion, and the first side portion 71 and the second side portion 72 are parallel to each other. An installation protrusion 74 is provided on the bottom portion 73, and the installation protrusion 74 is correspondingly arranged with at least one deformation gap 13 communicating with the end of the first connecting member 1. In this embodiment, the first connecting member 1 is installed into the installation channel 101 through the installation tool 7, or adjusted by the installation tool 7 after the first connecting member 1 is installed into the installation channel 101. The installation tool 7 in this embodiment directly cooperates with the deformation gap 13 of the first connecting member 1 through the installation protrusion 74. Thus, when the first side portion 71 and the second side portion 72 are respectively in contact with the top surface and the bottom surface of the first member 10, it can be ensured that the installation space of the first connecting member is in the same vertical plane as the first installation hole. Furthermore, after the first connecting member is installed in place, the installation space of the first connecting member can be accurately aligned with the first installation hole, eliminating the need to readjust the first connecting member again, reducing the trouble of repeatedly adjusting the installation position and installation angle of the first connecting member 1, and improving the installation efficiency.

[0116] Due to the small space of the deformation gap 13, only using the installation protrusion 74 to cooperate with the deformation gap 13 will result in poor stability between the installation tool 7 and the first connecting piece 1, leading to the situation that the first connecting piece 1 falls off from the installation tool 7 or the installation protrusion 74 separates from the deformation gap 13. Therefore, in some embodiments, a positioning portion 75 is provided on the bottom 73, and the positioning portion 75 cooperates with at least a part of the plug-in 4 or at least a part of the first connecting piece 1 so that the installation protrusion 74 is snapped into the deformation gap communicating with the end of the first connecting piece 1. By using the positioning portion 75 to cooperate with the plug-in 4 or the first connecting piece, the contact portion between the installation tool 7 and the first connecting piece 1 is increased, the cooperation stability between the installation tool 7 and the first connecting piece 1 is improved, and thus unnecessary operations are reduced and the installation efficiency is improved.

[0117] In some embodiments, as Figure 28 shown, the positioning portion 75 includes a positioning post 76. The cross-section of the positioning post 76 is adapted to the cross-section of the insertion channel 41. The cross-sectional shape of the positioning post 76 can be adjusted to be non-circular according to the insertion channel, for example, it can be triangular or square or hexagonal or octagonal or elliptical or waist-shaped or petal-shaped, etc. During the use of the installation tool 7, the positioning post 76 is inserted into the insertion channel 41 so that the installation protrusion 74 is snapped into the deformation gap communicating with the end of the first connecting piece 1, improving the installation efficiency.

[0118] In some embodiments, as Figure 25 shown, the positioning portion 75 includes a positioning recess 77. The cross-section of the positioning recess 77 is adapted to the outer cross-section of the plug-in 4. It can be understood that the plug-in 4 is pre-loaded into the first connection channel 11 before the first connecting piece 1 is installed into the installation channel 101, and the plug-in 4 is in the released position. The cross-section of the positioning recess 77 is adapted to the outer cross-section of the plug-in 4 so that the installation protrusion 74 is snapped into the deformation gap communicating with the end of the first connecting piece 1. In addition, during the installation process, it is also necessary to adjust the depth of the first connecting piece 1 installed in the installation channel 101 so that the installation space 12 corresponds to the position of the first installation hole 102. Therefore, during the actual installation process, the bottom 73 usually abuts against the end of the first connecting piece 1. The positioning recess 77 in this embodiment can be used to accommodate the plug-in 4 protruding from the end of the first connecting piece 1 and in the released position, so that the bottom 73 abuts against the end of the first connecting piece 1 during the installation process to adjust the depth of the first connecting piece 1 entering the installation channel 101, further improving the installation efficiency.

[0119] In some embodiments, as Figures 5-8As shown, there are two deformation gaps 13 connected to the end of the first connector 1, and the two deformation gaps 13 connected to the end of the first connector 1 are respectively arranged at the top and bottom of the end of the first connector 1. There are two installation protrusions, which are respectively arranged at the connection between the bottom and the first side 71, and the connection between the bottom and the second side 72, thereby improving the installation efficiency.
