Description

Technical Field

[0001] This invention relates to the field of wall panel assembly technology, and more specifically, to a connector and a composite wall panel. Background Technology

[0002] In the field of building decoration and renovation, composite wall panels are widely used in interior and exterior wall decoration due to their advantages such as convenient installation, good decorative effect, and superior thermal insulation performance. Composite wall panels are usually fixed to the wall or keel frame using connectors. Existing connectors are mostly fixed structures designed for rectangular wall panels. With the increasing demand for personalized decoration, the application of irregularly shaped decorative wall panels such as parallelograms and hexagons is becoming more and more widespread. However, traditional connectors are mostly of a single model, which can only be adapted to wall panels of specific shapes and sizes. When the wall panel shape changes, construction workers need to replace connectors of different specifications, resulting in a wide variety of materials, complicated selection, and poor construction continuity. Summary of the Invention

[0003] To address the aforementioned technical problems, the present invention provides a connector.

[0004] The technical solution is as follows:

[0005] A connector includes a connector body, the connector body including an adjustment component mounted on a wall and a mating component detachably disposed on the side wall of a wall panel. The adjustment component includes a cylindrical mounting base, a first mating arm fixedly connected to the outer wall of the mounting base and a fourth mating arm detachably symmetrical to the first mating arm along the axis of the mounting base, and a second mating arm and a third mating arm rotatably mounted on the outer wall of the mounting base for engaging with the first and fourth mating arms to form a fit against the external corner edge of the wall panel.

[0006] The first, second, third, and fourth mating arms each have through slots corresponding to the mating parts. A locking element is detachably installed at the center of the mounting base. The locking element is used to pass through the corresponding through slot and engage with the corresponding mating part to limit the movement of adjacent wall panels.

[0007] Furthermore, the second mating arm forms an installation area A and an installation area B between itself and the first and fourth mating arms for mating with the external corner edge of the wall panel, and the third mating arm forms an installation area C and an installation area D between itself and the first and fourth mating arms for mating with the external corner edge of the wall panel. The second and third mating arms are used to adjust the size of the installation areas A and B or C and D, respectively.

[0008] Furthermore, an inwardly recessed insertion cavity is provided at the center of the top wall of the mounting base, and an upper rotating cavity is provided at the top of the outer wall of the mounting base for the second mating arm to rotate. The upper rotating cavity is fan-shaped, and a lower rotating cavity is provided at the bottom of the outer wall of the mounting base for the third mating arm to rotate, and is symmetrically arranged with the upper rotating cavity.

[0009] Furthermore, the second mating arm has a first extension extending into the upper rotating cavity at its end, and a first collar portion that mates with the inner wall of the insertion cavity is connected to the end of the first extension portion. The third mating arm has a second extension extending into the lower rotating cavity at its end, and a second collar portion that mates with the inner wall of the insertion cavity is connected to the end of the second extension portion. A sleeve for the first collar portion and the second collar portion to be fitted is detachably installed on the bottom wall of the insertion cavity. A first mounting cavity and a first mounting chamber are respectively opened on the bottom walls of the first extension portion and the second extension portion. A locking component is installed in both the first mounting cavity and the first mounting chamber.

[0010] Furthermore, both the upper and lower rotating cavities have arc-shaped grooves on their bottom walls. The locking assembly includes a sliding plate slidably disposed within the first mounting cavity and an arc-shaped toothed ring disposed within the arc-shaped groove. The bottom wall of the first mounting cavity has a positioning block that engages with the arc-shaped toothed ring. A spring is connected between the top wall of the first mounting cavity and the top of the inner wall of the first mounting cavity. The spring is used to provide elastic force to keep the sliding plate pressed downward. A fixing rod that passes through the first mounting cavity is detachably installed on the top wall of the sliding plate. The top wall of the mounting base has two arc-shaped openings that communicate with the upper rotating cavity and the lower rotating cavity. The two arc-shaped openings are used to engage with the corresponding fixing rods. The top wall of the fixing rod passes through the lower rotating cavity and is flush with the top wall of the mounting base.

[0011] Furthermore, a positioning hole is provided on the top wall of the mounting base, and two insertion holes communicating with the positioning hole are provided on the outer wall of the mounting base. Two connecting rods that cooperate with the two insertion holes are connected to the end of the fourth mating arm. A through hole corresponding to the positioning hole is provided on the top wall of the connecting rod, and a through-hole bolt is threaded on the bottom wall of the positioning hole.

[0012] Furthermore, the bottom walls on both sides of the first mating arm have fixing parts that mate with the wall surface and the bottom wall of the wall panel. The mating parts have slots. The side walls on both sides of the first mating arm have fitting parts that mate with the right-angled edges of the wall panel. The top walls of the fitting parts are provided with through grooves corresponding to the slots. The bottom walls of the locking parts have multiple locking blocks that mate with the slots through the through grooves.

[0013] Furthermore, a slot is provided at the top wall of the first mating arm, and a decorative strip is attached to the slot. The decorative strip is used to mate with the top wall of the adjacent wall panel.

[0014] Furthermore, a recess is provided at the center of the top wall of the locking component, and a connecting bolt threaded onto the sleeve is rotatably installed at the bottom wall of the recess. A plug is detachably installed in the recess.

[0015] A composite wall panel having any of the connectors described above.

[0016] Based on the above description, the beneficial effects of the connector and composite wall panel of the present invention are as follows:

[0017] By setting the fourth mating arm as a symmetrical structure that can be detached along the axis of the mounting base, and combining it with the rotatable second and third mating arms, the limitations of the traditional wall panel connector structure being fixed and having a single form are broken. The fixed first and fourth mating arms and the mounting base can serve as a reference positioning structure to ensure the basic stability of the connector installation. The detachable fourth mating arm can be quickly disassembled and switched according to the shape requirements of the wall panel, which is suitable for the connection point requirements of different irregular wall panels such as square, hexagonal, and octagonal.

[0018] The locking component, through its locking block, penetrates the through slots and fittings on the first, fourth, second, and third mating arms in one go, achieving multi-point, synchronous limiting from the connector body to the wall panel. This combines multiple independent fixing steps into one operation. Construction workers only need to press down the locking component and tighten one connecting bolt to simultaneously lock all adjacent wall panels on a node, greatly simplifying the installation process. This avoids the problems of traditional connector locking structures, which are simple and can only achieve single-point limiting. After the wall panels are spliced, problems such as edge warping and displacement are easy to occur. Moreover, disassembly and assembly require disassembling and tightening bolts one by one, making inspection and maintenance cumbersome. In contrast, this structure, through multi-slot adaptation locking, can achieve multi-directional synchronous locking of multiple wall panel corners, with uniform limiting and high fixing strength, reducing problems such as wall panel edge loosening, warping, and displacement.

[0019] With the top wall of the fixed rod flush with the top wall of the mounting base, during use, the construction personnel can directly adjust the relative position of the second and third mating arms by rotating them. The operation is simple and quick. While the locking component limits the mating components on the wall panel, it also limits the top wall of the fixed rod, thereby pressing the sliding plate on the fixed rod and the positioning block on the sliding plate into the corresponding arc-shaped toothed ring to form a limit.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] The embodiments provided by the present invention will be described in detail below:

[0037] Example 1

[0038] like Figures 1 to 13 As shown, a connector includes a connector body 100. The connector body 100 includes an adjustment component 200 mounted on a wall and a mating component 400 detachably disposed on the side wall of a wall panel. The adjustment component 200 includes a cylindrical mounting base 210. A first mating arm 220 and a fourth mating arm 250 detachably symmetrical to the first mating arm 220 along the axis of the mounting base 210 are fixedly connected to the outer wall of the mounting base 210. A second mating arm 230 and a third mating arm 240 are rotatably mounted on the outer wall of the mounting base 210 for mating with the first mating arm 220 and the fourth mating arm 250 to form a fit against the external corner edge of the wall panel.

[0039] It should be noted that by setting the fourth mating arm 250 as a detachable symmetrical structure along the axis of the mounting base 210, and combining it with the rotatable second mating arm 230 and third mating arm 240, the limitations of the traditional wall panel connector structure being fixed and having a single form are broken. The fixed first mating arm 220, the fourth mating arm 250 and the mounting base 210 can serve as a reference positioning structure to ensure the basic stability of the connector installation. The detachable fourth mating arm 250 can be quickly disassembled and switched according to the wall panel shape requirements, and is suitable for the connection point requirements of different irregular wall panels such as square, hexagonal and octagonal.

[0040] Specifically, by setting the fourth mating arm 250 to be detachably connected to the mounting base 210, and setting the second mating arm 230 and the third mating arm 240 to be rotatable around the axis of the mounting base 210, this connector can be flexibly deformed according to the actual shape and number of wall panels to be installed. When the wall panel is square and the number of wall panels to be connected is four, the fourth mating arm 250 is retained, and four installation areas, installation area A, installation area B, installation area C and installation area D, can be formed to connect four wall panels.

[0041] When the wall panel is hexagonal or octagonal, and three wall panels need to be connected, the fourth mating arm 250 can be removed to quickly switch to a configuration that can accommodate three wall panels. This setting greatly reduces the variety of connectors required during construction, avoids frequent replacement of the entire set of connectors due to changes in the shape of the wall panel, and significantly improves the continuity and efficiency of construction.

[0042] The second mating arm 230 forms an installation area A and an installation area B between itself and the first mating arm 220 and the fourth mating arm 250 for mating with the external corner edge of the wall panel. The third mating arm 240 forms an installation area C and an installation area D between itself and the first mating arm 220 and the fourth mating arm 250 for mating with the external corner edge of the wall panel. The second mating arm 230 and the third mating arm 240 are used to adjust the size of the installation area A and the installation area B or the installation area C and the installation area D, respectively.

[0043] It should be noted that the rotation adjustment function of the second mating arm 230 and the third mating arm 240 can flexibly change the opening and closing dimensions and forming angle of the four installation areas: installation area A, installation area B, installation area C and installation area D. This allows each installation area to accurately match the external corner specifications of wall panels of different sizes and with different corner curvatures. It can simultaneously connect the external corner connection points of multiple adjacent wall panels, forming a multi-point synchronous limiting structure. This is different from the traditional connection method of single-point fixing and single connection of connectors, effectively improving the integrity and installation efficiency of wall panel splicing installation.

[0044] The first mating arm 220, the fourth mating arm 250, the second mating arm 230 and the third mating arm 240 each have a through groove 224 corresponding to the mating part 400. A locking part 260 is detachably installed at the axis of the mounting base 210. The locking part 260 is used to pass through the corresponding through groove 224 and engage with the corresponding mating part 400 to limit the movement of adjacent wall panels.

[0045] It should be noted that the locking component 260, through its locking block 262, penetrates the through slots 224 on the first mating arm 220, the fourth mating arm 250, the second mating arm 230, and the third mating arm 240, as well as the mating component 400, to achieve multi-point, synchronous limiting from the connector body 100 to the wall panel. This combines multiple independent fixing steps into one operation. Construction personnel only need to press down the locking component 260 and tighten one connecting bolt 261 to simultaneously lock all adjacent wall panels on a node, greatly simplifying the installation process. This avoids the problems of traditional connector locking structures, which are simple and can only achieve single-point limiting. After the wall panels are spliced, problems such as edge warping and displacement are easy to occur. Moreover, disassembly and assembly require disassembling the fastening bolts one by one, making inspection and maintenance cumbersome. In contrast, this structure, through multi-slot adaptation locking, can achieve multi-directional synchronous locking of multiple wall panel corners, with uniform limiting and high fixing strength, reducing problems such as wall panel corner loosening, warping, and displacement.

[0046] like Figures 5 to 9 As shown, the mounting base 210 has an inwardly recessed insertion cavity 211 at the center of the top wall axis, and an upper rotating cavity 212 for the second mating arm 230 to rotate at the top of the outer wall of the mounting base 210. The upper rotating cavity 212 is fan-shaped. The mounting base 210 has a lower rotating cavity 213 for the third mating arm 240 to rotate at the bottom of the outer wall, and is symmetrically arranged with the upper rotating cavity 212.

[0047] It should be noted that both the upper rotating cavity 212 and the lower rotating cavity 213 are arranged in a fan shape. The angle of the fan shape limits the maximum adjustment range of the second mating arm 230 and the third mating arm 240, preventing the second mating arm 230 and the third mating arm 240 from leaving the effective working area or interfering with other components due to excessive rotation.

[0048] Understandably, the symmetrical upper and lower cavity structure allows the adjustment actions of the second mating arm 230 and the third mating arm 240 to be independent and non-interfering with each other, enabling precise adjustment of the corresponding installation area.

[0049] The second mating arm 230 has a first extension 231 extending into the upper rotating cavity 212 at its end. The end of the first extension 231 is connected to a first collar 232 that mates with the inner wall of the insertion cavity 211. The third mating arm 240 has a second extension 241 extending into the lower rotating cavity 213 at its end. The end of the second extension 241 is connected to a second collar 242 that mates with the inner wall of the insertion cavity 211. A sleeve 270 for the first collar 232 and the second collar 242 to be fitted is detachably installed on the bottom wall of the insertion cavity 211. The bottom walls of the first extension 231 and the second extension 241 are respectively provided with a first mounting cavity 2311 and a first mounting cavity 2411. A locking component 600 is installed in both the first mounting cavity 2311 and the first mounting cavity 2411.

[0050] It should be noted that the insertion cavity 211 at the axis provides a precise positioning reference for the assembly of the sleeve 270, locking member 260, and connecting bolt 261, realizing the coaxial assembly of each component and ensuring the concentricity and assembly accuracy of the overall structure. At the same time, corresponding first mounting cavities 2311 and 2411 are opened inside the first extension 231 and the second extension 241, providing installation space for the locking assembly 600. The built-in locking assembly 600 can firmly lock the second mating arm 230 and the third mating arm 240 at the set angle position after adjustment. Even when subjected to the weight of the wall panel or external vibration, it can effectively prevent the angle from returning, ensuring the stability of the overall structure.

[0051] Both the upper rotating cavity 212 and the lower rotating cavity 213 have arc-shaped grooves on their bottom walls. The locking assembly 600 includes a sliding plate 610 slidably disposed in the first mounting cavity 2311 and an arc-shaped toothed ring 2121 disposed in the arc-shaped groove. The bottom wall of the first mounting cavity 2311 has a positioning block 620 that cooperates with the arc-shaped toothed ring 2121. A spring 630 is connected between the top wall of the first mounting cavity 2311 and the top of the inner wall of the first mounting cavity 2311. The spring 630 is used to provide... The sliding plate 610 is kept pressed down by the elastic force. A fixing rod 640 is detachably installed on the top wall of the sliding plate 610, passing through the first mounting cavity 2311. The top wall of the mounting base 210 is provided with two arc-shaped openings 214 that communicate with the upper rotating cavity 212 and the lower rotating cavity 213. The two arc-shaped openings 214 are used to cooperate with the corresponding fixing rods 640. The top wall of the fixing rod 640 passes through the lower rotating cavity 213 and is flush with the top wall of the mounting base 210.

[0052] It should be noted that the engagement between the arc-shaped toothed ring 2121 and the positioning block 620 achieves the positioning and locking of the second mating arm 230 and the third mating arm 240 after rotational adjustment. Combined with the pressing action of the spring 630, the positioning block 620 is always tightly fitted with the arc-shaped toothed ring 2121 to prevent loosening of the engagement.

[0053] Furthermore, since the top wall of the fixing rod 640 is flush with the top wall of the mounting base 210, during use, the construction personnel can directly adjust the relative position of the second and third mating arms 230 and 240 by rotating them. The operation is simple and quick. While the locking part 260 limits the mating part 400 on the wall panel, it also limits the top wall of the fixing rod 640, thereby pressing the sliding plate 610 on the fixing rod 640 and the positioning block 620 on the sliding plate 610 into the corresponding arc-shaped toothed ring 2121 to form a limit.

[0054] like Figure 4 and Figure 5 As shown, a positioning hole 216 is provided on the top wall of the mounting base 210, and two insertion holes 215 communicating with the positioning hole 216 are provided on the outer wall of the mounting base 210. Two connecting rods 251 that cooperate with the two insertion holes 215 are connected to the end of the fourth mating arm 250. A through hole 252 corresponding to the positioning hole 216 is provided on the top wall of the connecting rod 251, and a pin bolt 500 that passes through the through hole 252 is threaded on the bottom wall of the positioning hole 216.

[0055] It should be noted that the double-hole 215 and double-connecting rod 251 are used to connect and position the second fixed arm 250 and the mounting base 210, achieving precise alignment and assembly. The double-point insertion effectively prevents the second fixed arm 250 from rotating or shifting, ensuring the coaxiality and stability of the assembly. The pin bolt 500 passes through the positioning hole 216 and the through hole 252 to complete the axial locking, enabling the quick disassembly and fixing of the second fixed arm 250. The disassembly and assembly operation is simple and efficient. The second fixed arm 250 can be quickly disassembled according to the shape requirements of the wall panel, adapting to the installation requirements of irregular wall panels with few connection points such as hexagons and octagons. It realizes that one connector can be used for multiple wall panels, greatly reducing the cost of construction materials and accessories. At the same time, the structure can be switched quickly, effectively ensuring the continuity of construction.

[0056] like Figure 5 As shown, the bottom walls on both sides of the first mating arm 220 have fixing parts 221 that mate with the wall surface and the bottom wall of the wall panel. The mating part 400 has a slot. The side walls on both sides of the first mating arm 220 have fitting parts 222 that mate with the right-angle edge of the wall panel. The top wall of the fitting parts 222 is provided with through grooves 224 corresponding to the slots. The bottom wall of the locking part 260 has multiple locking blocks 262 that pass through the through grooves 224 and mate with the slots.

[0057] It should be noted that the fixing part 221 provides a fulcrum for the bottom wall of the wall panel to cooperate with the wall surface, so as to realize the stable connection of the wall panel. The fitting part 222 precisely fits with the right-angle edge of the wall panel, realizing the lateral limit of the wall panel installation and preventing the wall panel from shifting to the left or right. At the same time, the through groove 224 corresponds one-to-one with the slot of the mating part 400 and the locking part 260 and the locking block 262, forming a three-dimensional limiting structure with wall surface fixing, side wall fitting and top locking, which restricts the displacement freedom of the wall panel in all directions.

[0058] A slot 223 is provided on the top wall of the first mating arm 220. A decorative strip 300 is engaged with the slot 223. The decorative strip 300 is used to mate with the top wall of the adjacent wall panel. The locking member 260 has the same width as the decorative strip 300, so the locking member 260 can also limit the movement of multiple wall panels at the connection node at the same time. Figure 2 The state.

[0059] It should be noted that the decorative strip 300 can be detachably snapped together by means of the slot 223. The decorative strip 300 can cover the exposed structure at the top of the connector and the gap between the wall panel and the joint, which serves to cover and protect and beautify the decoration. The snap-fit ​​assembly structure does not require glue, bolts or other auxiliary fixing accessories, and is easy to disassemble and assemble. It can be assembled uniformly after the wall panel is installed, which is compatible with the overall decoration construction process. At the same time, it can also form a pressing limit on the top of the wall panel to help fix the wall panel.

[0060] like Figure 3 As shown, a recess is provided at the center of the top wall of the locking member 260, and a connecting bolt 261 threadedly connected to the sleeve 270 is rotatably installed at the bottom wall of the recess. A plug 280 is detachably installed at the recess.

[0061] It should be noted that the threaded engagement between the connecting bolt 261 and the sleeve 270 enables the vertical lifting and lowering adjustment of the locking component 260. The insertion depth of the locking block 262 can be precisely adjusted according to the wall panel thickness to meet the installation requirements of wall panels of different thicknesses. The recessed part provides operating space for the disassembly, assembly, and tightening of the connecting bolt 261. At the same time, the removable plug 280 can close the recess, hide the connecting bolt 261 and other fasteners, prevent exposed parts from accumulating dust and rust, and ensure that the top of the connector is flat and aesthetically pleasing.

[0062] Specifically, taking a conventional square wall panel as an example, it requires the connection of four wall panels. During use, the installer first pre-fixes the adjusting assembly 200 to the wall surface using the first expansion bolt. Then, according to the installation direction of the wall panels to be installed, the positions of the first mating arm 220 and the fourth mating arm 250 are adjusted. The fixing parts 221 on the first mating arm 220 and the fourth mating arm 250 are then fixed using the second expansion bolt. Finally, the adjusting assembly 200 is fixed by tightening the first expansion bolt. After this is completed, the installer rotates the second mating arm 230 and the third mating arm 240 to a position perpendicular to the first mating arm 220 and the fourth mating arm 250, as shown in [reference needed]. Figure 1 and Figure 2 The position and fixation of the adjustment component 200 can be completed in the state shown.

[0063] Next, the construction workers install the mating component 400 onto the side corner of the wall panel to be installed using screws. Using installation area A as the installation origin, the wall panel corner with the mating component 400 installed is sequentially installed into installation areas B, C, and D. It is then used sequentially with the adjustment assembly 200 connected to the adjacent wall panel for positioning. This is achieved by first rotating the second mating arm 230 to adjust installation area A to the size corresponding to the wall panel, and then installing it onto the corresponding wall panel corner. (See...) Figure 2 In the state shown, the fixing part 221 on the first mating arm 220 located outside the wall panel is fixed by the second expansion bolt. Then, the adjustment assembly 200 for connecting with the adjacent wall panel is fixed by the first expansion bolt. Next, the fixing part 221 on the fourth mating arm 250 is fixed by the second expansion bolt. The third mating arm 240 is adjusted to be perpendicular to the fourth mating arm 250. Then, the corresponding wall panels in the installation areas B, C and D are removed. Finally, the fixing part 221 on the remaining side of the first mating arm 220 is fixed by the second expansion bolt.

[0064] After the adjustment assembly 200 for connecting with adjacent wall panels is installed, the locking block 262 on the locking member 260 is inserted into the through slot 224 on the corresponding first mating arm 220, second mating arm 230, third mating arm 240, and fourth mating arm 250. Then, the wall panels are installed into the corresponding installation areas A, B, C, and D. The locking member 260 is pressed down to insert the locking block 262 on the locking member 260 into the slot on the corresponding mating member 400, thus completing the initial positioning of the wall panels in the corresponding installation areas A, B, C, and D. At this time, the construction personnel can tighten the connecting... Bolt 261 is tightened into sleeve 270. Locking member 260 blocks the fixing rod 640 in locking assembly 600, thereby pressing the sliding plate 610 on the fixing rod 640 and the positioning block 620 on the sliding plate 610 into the corresponding arc-shaped toothed ring 2121 to form a limit. This limits the second mating arms 230 and 240 and the mating member 400 on the wall panel, thus completing the final limit of the wall panel. The wall panel installation can be completed by repeating the process. After all the installation is completed, the wall panel installation is completed by snapping the decorative strip 300 into the slot 223. See Figure 1 The state shown;

[0065] When the wall panel is of other polygonal shapes, such as hexagonal or octagonal, three wall panels need to be connected. During use, the installer removes the bolt 500 by loosening it, thus releasing the bolt from its restraint on the connecting rod 251 on the fourth mating arm 250. The installer can then remove the fourth mating arm 250 to complete the adjustment.
