Description

Technical Field

[0001] This utility model relates to the field of furniture connector technology, and in particular to a connector with multi-angle adjustment. Background Technology

[0002] To improve aesthetics, concealed connectors are increasingly being used to connect two furniture panels, thereby enhancing the furniture's appearance. Among these, two-in-one or three-in-one concealed connectors are widely used for connecting two furniture panels.

[0003] In existing technologies, such as Figures 1-2 As shown, some finished furniture pieces are made by tightly connecting two panels through inclined surfaces, which helps to improve the aesthetics of the finished furniture. In order to achieve the connection between the two panels of this type of finished furniture, some existing two-in-one or three-in-one connectors have a multi-angle adjustable connector 1' which is formed by pivotally connecting a first component 11' and a second component 12'. In use, firstly, connecting holes are machined on the inclined surfaces of the two panels respectively. Then, the first component 11' is fastened to the connecting hole of one of the panels by means of a threaded connection. Next, the second component 12' is rotated around the first component 11' by a certain angle, and the end of the second component 12' away from the first component 11' is inserted into the mounting hole of the other panel and locked with the eccentric wheel 2', thereby achieving a concealed connection between the two panels through the inclined surfaces.

[0004] However, this type of connector has two problems. First, the first component needs to be threaded into the connecting hole of one of the panels, which not only increases the complexity of installation, but also makes it easy for the installation angle to be incorrect if the first component is screwed off. In this case, the connecting hole cannot be used again and an additional connecting hole needs to be drilled. Second, since the second component is inserted into the mounting hole of another panel, there is a gap between the outer peripheral sidewall of the second component and the inner sidewall of the mounting hole, which makes it easy for the two panels to be misaligned after connection, affecting the aesthetics of the finished furniture. Utility Model Content

[0005] Therefore, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a connector that can be adjusted at multiple angles.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A multi-angle adjustable connector includes: two insert parts and a rotating shaft;

[0008] One end of each of the two insertion components is pivotally connected by the pivot shaft. The insertion component is rotatable about the axis of the pivot shaft. The insertion component includes a rotating connecting part, a rod part, a locking part, and a protrusion part. The rotating connecting part and the locking part are respectively disposed at both ends of the rod part. The rotating connecting part is used to connect with the pivot shaft, and the locking part is used to connect with the eccentric wheel. The protrusion part is disposed around the rod part. The protrusion part includes a plurality of ribs evenly arranged along the circumference of the rod part. The ribs extend along the axial direction of the rod part.

[0009] In one embodiment, the size of the protrusion is larger than the size of the rod, the locking part, and the rotating connection part in the radial direction of the rod.

[0010] In one embodiment, the cross-sectional shape of the rib is one or more of the following: a circular arc protrusion and a serrated body.

[0011] In one embodiment, the rod is further provided with an operating part, the cross-section of which is adapted to the cross-section of the sleeve.

[0012] In one embodiment, the rotating connecting part, the rod part, and the locking part are integrally formed metal parts, and the protrusion and the operating part are plastic parts formed on the rod part.

[0013] In one embodiment, the locking part is a frustum structure, and the size of the locking part is larger than that of the rod in the radial direction.

[0014] In one embodiment, one of the inserting components has a pair of fork arms in its rotating connection portion, and the other inserting component has a connecting block that is inserted into the pair of fork arms. Both the pair of fork arms and the connecting block are provided with connecting holes through which the rotating shaft passes.

[0015] This application discloses a connecting assembly, which includes an eccentric wheel and a multi-angle adjustable connector as described above.

[0016] The eccentric wheel has an eccentric groove, and at least one inner sidewall of the eccentric groove is provided with a clamping arm;

[0017] The eccentric wheel is rotatable in a rotational direction between the release position and the locked position; when the eccentric wheel is in the release position, a portion of the rod and the locking part are inserted into the eccentric groove from the opening of the eccentric groove; when the eccentric wheel is in the locked position, the clamping arm restricts the locking part from being pulled out of the eccentric groove.

[0018] Thus, when the insertion component of this embodiment is placed within the mounting channel, the protrusion of the insertion component reduces the gap between the insertion component and the inner wall of the mounting channel, limiting the radial displacement of the insertion component along the mounting channel. This restricts misalignment between the first and second plates, improving the overall aesthetics. Furthermore, the multi-angle adjustable connector of this application has two insertion components. These components are positioned inside the plates via eccentric wheels, eliminating the need for threaded connections and simplifying installation. Additionally, the insertion components do not damage the inner wall of the mounting channel, preventing damage caused by tightening.

[0031] Please see Figures 3 to 7 This application provides a connecting assembly, including a multi-angle adjustable connector 1 and an eccentric wheel 2. The multi-angle adjustable connector 1 includes two insertion parts 11 and a rotating shaft 12. One end of the two insertion parts 11 is pivotally connected through the rotating shaft 12. The insertion parts 11 can rotate around the axis of the rotating shaft 12, so that the two insertion parts 11 can rotate relative to each other to the required angle to adapt to the fit between plates of different angles.

[0032] The insertion component 11 includes a rotating connection part 111, a rod part 112, a locking part 113, and a protrusion part 114. The rotating connection part 111 and the locking part 113 are respectively disposed at both ends of the rod part 112. The rotating connection part 111 is used to connect with the rotating shaft 12, and the locking part 113 is used to connect with the eccentric wheel 2. The protrusion part 114 is arranged around the rod part 112. The protrusion part 114 includes a plurality of ribs 1141 evenly arranged along the circumferential direction of the rod part 112. The ribs 1141 extend along the axial direction of the rod part 112.

[0033] The eccentric wheel 2 has an eccentric groove 21, and at least one inner sidewall of the eccentric groove 21 is provided with a clamping arm 22. The eccentric wheel 2 is rotatable in a rotational direction between a released position and a locked position; when the eccentric wheel 2 is in the released position, a portion of the rod portion 112 and the locking portion 113 are inserted into the eccentric groove 21 from the opening; when the eccentric wheel 2 is in the locked position, the clamping arm 22 prevents the locking portion 113 from being pulled out of the eccentric groove 21.

[0034] like Figure 5As shown, in use, the first insertion component 11 is inserted into the mounting channel 5 opened on the inclined surface of the first plate 3. Then, the first eccentric wheel 2 is inserted into the interior of the first plate 3 from the top of the insertion component 11. The eccentric wheel 2 is rotated to lock the eccentric wheel 2 and the locking part 113 together. Then, the included angle between the second insertion component 11 and the first insertion component 11 is adjusted so that the second insertion component 11 is inserted into the mounting channel 5 opened on the inclined surface of the second plate 4. Then, the second eccentric wheel 2 is inserted into the interior of the second plate 4 from the top of the second insertion component 11. The eccentric wheel 2 is rotated to lock the eccentric wheel 2 and the locking part 113 together. Thus, the inclined surface of the first plate 3 and the inclined surface of the second plate 4 are implicitly connected through the connecting component of this utility model.

[0035] In order to place the insertion component 11 and the eccentric wheel 2 inside the first plate 3 and the second plate 4, before assembly, a circular cross-section mounting channel 5 and a mounting hole 6 for mounting the eccentric wheel 2 are respectively provided on the inclined surfaces of the first plate 3 and the second plate 4.

[0036] Thus, when the insertion component 11 of this embodiment is placed in the mounting channel 5, the protrusion of the insertion component 11 reduces the gap between the insertion component 11 and the inner wall of the mounting channel 5, limiting the radial displacement of the insertion component 11 along the mounting channel 5, thereby limiting the misalignment of the first plate 3 and the second plate 4 and improving the overall aesthetics. Meanwhile, the multi-angle adjustable connector 1 of this application has two insertion components 11, which are positioned inside the plate by the eccentric wheel 2, eliminating the need for threaded connection with the plate, simplifying the installation operation. Furthermore, the insertion component 11 does not damage the inner wall of the mounting channel 5, avoiding damage caused by tightening.

[0037] It is understood that, in the radial direction of the rod portion 112, the size of the protrusion 114 is larger than the size of the rod portion 112, the locking portion 113 and the rotating connection portion 111. Therefore, it can be ensured that when the insertion component 11 is inserted into the mounting channel 5, the protrusion 114 contacts the inner wall of the mounting channel 5 first, thus limiting the occurrence of displacement.

[0038] In some embodiments, the cross-sectional shape of the rib 1141 is one or more of the following: a circular arc protrusion and a serrated body.

[0039] In some embodiments, the rod portion 112 is further provided with an operating portion 115, the cross-section of which is adapted to the cross-section of the sleeve. A socket wrench is a commonly used tool in the art, such as a manual socket wrench. During the rotation of the sleeve by the socket wrench, the operating portion 115 can be driven to rotate synchronously with the sleeve, thereby driving the insertion component 11 to rotate, facilitating the insertion component 11 into the installation channel 5. Furthermore, the operating portion 115 is located between the protrusion 114 and the locking portion 113.

[0040] In some embodiments, the rotating connecting part 111, the rod part 112, and the locking part 113 are integrally formed metal parts, which can be made of iron, stainless steel, or alloy steel, etc., allowing for rapid production through machining. The protrusion 114 and the operating part 115 are plastic parts molded on the rod part 112. The protrusion 114 and the operating part 115 can be wrapped around the rod part 112 by means of adhesive bonding or sleeve. The fact that the protrusion 114 is made of plastic allows the user to easily modify its shape and size to fit smaller installation channels 5.

[0041] Specifically, the locking part 113 has a frustum structure, and in the radial direction of the rod part 112, the size of the locking part 113 is larger than that of the rod part 112.

[0042] Specifically, in this embodiment, one of the insertion components 11 has a pair of fork arms 101 in its rotating connection portion 111, and the other insertion component 11 has a connecting block 102 inserted into the pair of fork arms 101. Both the pair of fork arms 101 and the connecting block 102 are provided with connecting holes 103 for the rotating shaft 12 to pass through.

[0043] In some embodiments, the structure of the eccentric wheel 2 in this utility model is the same as that of the existing eccentric wheel 2, and will not be described again here.

[0044] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
