Description

Technical Field

[0001] The present invention relates to the technical field related to building decoration, and in particular to a multifunctional corner line profile and a ceiling system using the same. Background Art

[0002] At present, the commonly used ceiling for house decoration is generally composed of a combination of decorative panels arranged horizontally and vertically. The decorative panels arranged in two directions are directly installed on the keel. The assembled decorative panels are easy to form joints at the corners. Although the joints of the ceiling system can be covered by plastering and filling, such a process is complicated and cumbersome; and the stress on the decorative panels at the corners is relatively concentrated, and the connection strength is relatively weak. The deformation or displacement of the keel will cause the decorative panels to deform, and even the joints between the decorative panels will crack, which seriously affects the aesthetics of the ceiling system. Later, in order to solve the problem of cracking of the joints, people invented corner connectors. For example, the Chinese utility model patent with the publication number CN211229313U discloses a laminated integrated board positive angle profile, which includes a positive angle decorative panel and two socket components. The positive angle decorative panel is a quarter of a circular arc, and the inner side of the socket is provided with barbs. The two socket components are connected through the positive angle decorative panel. In this way, when installing the ceiling, the two decorative panels can be connected and installed together through the positive angle profile, and the installation efficiency is high. However, in this connection method, the decorative panels are still mainly supported by the keel, and the external angle profile is only suitable for connecting lighter decorative panels. Moreover, the external angle profile is not fixed and it is easy to form gaps or fall off due to deformation or displacement of the decorative panels. Summary of the invention

[0003] In view of the problems in the prior art that the decorative panels at the corners of the suspended ceiling decorative panels are not firmly installed and connected, and the connection between the external angle profile and the decorative panel is easily displaced and detached, the present invention proposes a multifunctional corner line profile for suspended use, which, in cross section, comprises a frame-shaped main body, wherein the main body comprises at least four wall bodies, namely, an upper wall body, a lower wall body, a left wall body and a right wall body; characterized in that a first upper guide arm and a second upper guide arm extending upward are arranged on the upper wall body, the second upper guide arm is located on the left side of the first upper guide arm, and a first socket open upward is formed between each other, and a right card slot is arranged on the right side of the first upper guide arm, and the right card slot is used to connect a lifting ear; a first right guide arm extending rightward is arranged on the right wall body, and the right end portion of the first right guide arm is bent upward to form a plug-in arm that can be inserted into a keel; a first left guide arm extending leftward is arranged on the left wall body, and the left end portion of the first left guide arm is bent upward to have a third upper guide arm, and a lamp trough open upward is formed between the third upper guide arm and the second upper guide arm.

[0004] The main body is the main support of the corner profile, and the frame-like structure gives it good structural strength. Connecting other components (such as decorative panels or lifting ears) through the main body is conducive to reducing deformation.

[0005] The first upper arm is a connecting member connected to the upper wall, and has at least two connecting functions. One is that it can be connected to the lifting ear through the right slot on its right side, and the lifting ear is fixedly connected to the pull rod, so that the corner line profile is connected and fixed to the pull rod; the second is that it can be combined with the second upper arm to form the first socket on its left side, and the side vertical board inserted vertically can be accommodated and connected through the first socket. Compared with the prior art, the corner line profile of the present invention is used as a fixing part, and the decorative panel is supported by the corner line profile as a connecting part.

[0006] The plug-in arm is a component used to be plugged into the keel. Through the connection of the keel, it can be connected to the right side of the corner line profile and can also be inserted into the keel's side material or ceiling hanging board. Furthermore, a breaking groove is provided at the root of the plug-in arm connected to the first right guide arm, and the root of the breaking groove is connected to the first right guide arm. In this way, the plug-in arm can be easily and neatly broken at the position of the breaking groove, and the first right guide arm becomes a cantilever extending laterally to form a connection structure capable of supporting the horizontal decorative panel.

[0007] Among them, the first left guide arm and the third upper guide arm are components connected to the left wall. Looking from bottom to top, the first left guide arm, the third upper guide arm and the lower wall of the main body or part of the left wall serve as exposed walls, which can make the corner line profile after installation form an obvious cantilever arm extending outward.

[0008] According to the above technical solution, compared with the prior art, the beneficial technical effects of the present invention are:

[0009] First, the vertically arranged side panels can be connected through the first socket, and the horizontally arranged bottom panels can be connected through the plug-in arm, so that the corner line profile can well connect the vertical and horizontal decorative panels;

[0010] Second, the corner line profile can be connected to the lifting ear through the right slot of the first upper guide arm, and the lifting ear is connected to the roof through a pull rod, so that the corner line profile can be fixed and will not fall off due to deformation or displacement of the decorative panel. Using the corner line profile to fix or support the decorative panel is conducive to making the connection between the corner line profile and the decorative panel more stable.

[0011] Thirdly, the first left guide arm and the third upper guide arm are in a posture of being suspended and extended to the left, and the corner line profile forms a multi-layered effect visually; further, after placing lighting fixtures in the lamp trough, the ceiling system composed of the corner line profile and the decorative panel can have a more obvious sense of layering and a lighting effect. Obviously, the corner line profile can greatly increase the layered visual and lighting functions of the ceiling system.

[0012] In order to further increase the function of the corner wire profile, a further technical solution may be that a fourth upper arm is further provided on the first left guide arm, the fourth upper arm is located between the third upper arm and the second upper arm, and a second socket with an open opening facing upward is formed between the fourth upper arm and the third upper arm. The second socket can also accommodate the vertically inserted side panels, so that the corner wire profile has two upward plug-in ports, and the decorative panel can be selectively plugged into the first socket or the second socket. The two plug-in methods produce different decorative effects to meet different usage requirements. If the first socket is selected, the left side of the corner wire profile is suspended to give the ceiling system a sense of hierarchy; if the second socket is selected, the left side of the ceiling system is vertically closed, which can effectively reduce dust accumulation.

[0013] A further technical solution may be that the lower wall is provided with a groove with an opening facing downward, and the two side walls of the groove are provided with convex ribs arranged opposite to each other near the opening, and the opening of the groove is in a constricted shape when viewed from a cross section. The lower wall is a visible wall, and the provision of the groove can not only increase the shape of the lower surface, but also allow decorative pieces of different colors or materials to be placed in the groove to improve the visual effect of the appearance of the corner line profile.

[0014] A further technical solution may be that the right end of the first left guide arm is connected to the middle or top of the left wall, and the first left guide arm, the left wall and the lower wall form a step shape, which can increase the layering of the corner line profile and thus improve the overall layering effect of the ceiling system.

[0015] Since the corner profile has the above advantages, it can be used in a ceiling system, which includes a tie rod, a lifting ear, a side plate and the corner profile. The upper end of the tie rod is fixedly connected to the roof, one end of the lifting ear is connected to the tie rod and the other end is provided with a buckle matching the right slot, through which the corner profile can be connected to the tie rod, and the side plate can be vertically plugged into the first socket or the second socket. It also includes a keel, a connecting side material and a bottom plate, the connecting side material includes a mounting arm that can be inserted into the keel and a side material plug-in port that is arranged on the right side of the mounting arm and opens to the right, the connecting side material is connected to the corner profile through the keel, and the bottom plate can be horizontally plugged into the side material plug-in port.

[0016] In order to increase the lighting effect of the ceiling system, a further technical solution may be that it further includes a lighting fixture, and when the side plate is plugged into the first socket, the lighting fixture is arranged in the lamp trough. Furthermore, a support arm for supporting the lighting fixture to tilt may be arranged on the second upper arm, and the lighting fixture may have a certain inclination angle through the support arm to achieve a better lighting effect and reduce the vertical height of the lighting fixture.

[0017] In order to increase the air supply and exhaust function of the ceiling system, a further technical solution may be to further include a duct machine, the side vertical plate is provided with a duct through hole, and the duct machine is installed in the duct through hole. In particular, when the decorative plate is plugged into the first socket, the duct machine is installed in the inner position of the ceiling system to form a hidden air supply, so that the ceiling system is both simple in appearance and practical.

[0018] Since the present invention has the above characteristics and advantages, it can be applied to a suspended corner line profile and a ceiling system using the same. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following further describes the structure of the corner profile 5 and the ceiling system using the technical solution of the present invention in conjunction with the accompanying drawings. Except for the embodiments that are explicitly described as equivalent or optional, the various implementation details disclosed below can be selectively applied or combined in one embodiment even if there is no direct correlation or synergy in terms of function.

[0025] like Figure 3 As shown, the ceiling system includes a decorative panel, the decorative panel includes a vertically arranged side panel 11 and a horizontally arranged bottom panel 12, the side panel 11 and the bottom panel 12 form the side wall and the bottom wall of the ceiling system and define the upper space of the ceiling system at the same time; it also includes a tie rod 2, a hanging ear 4 and a corner line profile 5, wherein the upper end of the tie rod 2 is connected to the ceiling wall panel, the hanging ear 4 is L-shaped, a through hole is provided on the horizontal wall of the hanging ear 4, the hanging ear 4 is sleeved on the tie rod 2 through the through hole and connected together by a nut, and a buckle 41 is provided on the vertical wall of the hanging ear 4, and is connected to the corner line profile 5 through the buckle 41. The corner line profile 5 is arranged at the corner of the side panel 11 and the bottom panel 12 and is used to connect and support the side panel 11 and the bottom panel 12, so as to form a ceiling system with the corner line profile 5 as a supporting connector.

[0026] Furthermore, in order to increase the air supply and exhaust functions of the ceiling system, a duct machine 6 is further included. The side vertical plate 11 vertically plugged into the corner line profile 5 is provided with an air duct through hole, and the duct machine 6 is installed in the air duct through hole. In this way, the duct machine 6 is arranged in the upper space of the ceiling system, which not only utilizes the upper space, but also increases the air supply and exhaust functions of the ceiling system.

[0027] In order to make the corner profile 5 better connect the decorative plate and the lifting ear 4, the following Figure 1 and Figure 2 The structure of the corner line profile 5 is further explained. From the cross-section, it includes a frame-shaped main body, and the main body includes at least four walls, namely an upper wall 71, a lower wall 72, a left wall 73 and a right wall 74. The frame-shaped structure gives the main body good structural strength, and is less likely to deform when the corner line profile 5 is connected to other components (such as decorative panels or lifting ears 4), which is beneficial to improving the problem of decorative panels falling off due to deformation of the corner line profile 5.

[0028] Furthermore, the upper wall body 71 is provided with a first upper guide arm 81 and a second upper guide arm 82 extending upward. The second upper guide arm 82 is located on the left side of the first upper guide arm 81 and forms a first socket 83 with an opening facing upward. The first socket 83 is used to accommodate and connect the vertically inserted side plate 11. In order to allow the inserted side plate 11 to form a more stable connection relationship with the corner line profile 5, a wave pattern is also provided on the wall surface of the first upper guide arm 81 and the second upper guide arm 82 facing the first socket 83, which is conducive to increasing the connection strength between the corner line profile 5 and the side plate 11 and thus improving the connection stability. The right side of the first upper guide arm 81 is provided with a right card slot 811, and the right card slot 811 matches the buckle 41 on the lifting ear 4. In actual implementation, since the corner line profile 5 is a profile body, in order to form a stable connection support in the axial direction, it is usually necessary to arrange a plurality of the pull rods 2 and the lifting ears 4 at intervals along the axial direction of the corner line profile 5.

[0029] In order to connect the transversely arranged bottom plate 12, a first right guide arm 84 extending to the right is provided on the right wall 74, and the right end of the first right guide arm 84 is bent upward to form a plug-in arm 85 that can be inserted into the keel 3. The upper end of the plug-in arm 85 is provided with a protrusion so that it can be clamped by the two clamping arms of the keel 3. Since there are various ways to connect the bottom plate 12 with the corner line profile 5, three commonly used connection methods are described below:

[0030] The first connection method, such as Figure 5 As shown, the ceiling system also includes a keel 3, the base plate 12 is an aluminum gusset plate, and the edge of the aluminum gusset plate is provided with an upwardly turned clamping edge, and the clamping edge can be inserted into the keel 3 so that the aluminum gusset plate and the corner line profile 5 are connected together.

[0031] The second connection method, such as Figure 3 As shown, the bottom plate 12 is a block-shaped plate (for example, wood board, plywood, honeycomb plate, etc.). This type of plate is not inserted into the clamping structure of the keel 3. In order to enable the plate to be connected to the keel 3, a connecting member 31 is also provided on the side of the plate. The connecting member 31 includes a vertically arranged connecting arm 311 and a first clamping arm 312 and a second clamping arm 313 arranged at the lower end of the connecting arm 311. The first clamping arm 312 and the second clamping arm 313 arranged at intervals form a connecting bayonet 310 for connecting the plate, and the connecting arm 311 is an arm body that can be inserted into the keel 3, so that the plate is connected to the corner line profile 5 through the connecting member 31.

[0032] The third connection method, such as Figure 2 and Figure 4As shown, a breaking groove 851 is provided at the root where the plug-in arm 85 is connected to the first right guide arm 84, and the root of the breaking groove 851 is connected to the first right guide arm 84. In this way, the plug-in arm 85 can be easily and neatly broken at the position of the breaking groove 851, and the first right guide arm 84 becomes a laterally extending cantilever, thereby becoming a supporting member of the base plate 12. The base plate 12 is connected to the corner line profile 5 by overlapping the first right guide arm 84.

[0033] In order to improve the overall aesthetics of the ceiling system and increase the function of the corner line profile 5, a first left guide arm 86 extending to the left is provided on the left wall 73. The left end of the first left guide arm 86 is bent upward to have a third upper guide arm 87, and an open lamp trough 15 facing upward is formed between the third upper guide arm 87 and the second upper guide arm 82. The right end of the first left guide arm 86 is connected to the middle of the left wall 73, and the first left guide arm 86, the left wall 73 and the lower wall 72 form a step shape. From the bottom to the top, the first left guide arm 86, the third upper guide arm 87, the lower wall 72 of the main body and part of the left wall 73 are exposed walls. After the ceiling system is installed, the left side of the corner line profile 5 is arranged in a suspended state, which greatly increases the layering of the corner of the ceiling system and improves the overall visual effect of the ceiling system. In addition, a lighting fixture 14 may be placed in the light trough 15 , thereby increasing the lighting function of the corner line profile 5 .

[0034] In order to further increase the function of the corner profile 5, such as Figure 3 and Figure 4 As shown, a further technical solution may be that a fourth upper arm 88 is further provided on the first left guide arm 86, and the fourth upper arm 88 is located between the third upper arm 87 and the second upper arm 82, and a second socket 89 with an open opening facing upward is formed between the fourth upper arm 88 and the third upper arm 87. The second socket 89 can also accommodate the vertically inserted side panel 11, so that the corner line profile 5 has two upward plug-in ports, and the side panel 11 can be selectively plugged into the first socket 83 or the second socket 89, and the two plug-in methods produce different decorative effects. The first is that the side panel 11 is plugged into the first socket 83 as described above, and the left side of the corner line profile 5 is suspended, so that the ceiling system has a sense of hierarchy. The second is as Figure 4 As shown, the side vertical plate 11 is plugged into the second socket 89, and the side vertical plate 11 is connected to the third upper guide arm 87, which makes the left side of the ceiling system vertically closed, thereby helping to reduce dust accumulation on the first left guide arm 86 and the upper wall 71. Of course, in this embodiment, the installation arrangement of the duct machine 6 is not affected.

[0035] A further technical solution may be that the lower wall 72 is provided with a groove 720 with an opening facing downward, and two groove side walls of the groove 720 are provided with convex ribs 721 arranged opposite to each other near the opening, such as Figure 2 As shown, the opening of the groove 720 is in a constricted shape. The lower wall 72 is a visible wall. By providing the groove 720, the shape of the lower surface can be increased; Figure 3 As shown, decorative sheets 9 of different colors or materials can also be placed in the groove 720 to increase the layering and aesthetics of the corner line profile 5 and the ceiling system.

[0036] Further, such as Figure 5 As shown, the ceiling system also includes a height-raising member 42, which is also a profile body. A slide groove 43 is provided at the lower end of the height-raising member 42, and the slide groove 43 can match the right card slot 811 originally used to connect the lifting ear 4, and the height-raising member 42 is connected to the corner line profile 5 through the slide groove 43; a connecting card slot 44 is provided at the upper end of the height-raising member 42, and the connecting card slot 44 matches the buckle 41 on the lifting ear 4, and the corner line profile 5 is connected to the lifting ear 4 through the height-raising member 42. In addition to playing a connecting role, the height-raising member 42 can also be used as a vertically arranged side panel 11 for ceilings with a small floor height that do not require the duct machine 6 to be placed.
