DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should be noted that the embodiments in this application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0031] A hanging assembly for a flat low-position ceiling according to the present invention, such as Figure 1-3 As shown, it includes a main keel 2 fixedly connected to the suspension rod 1, a secondary keel 3 fixedly connected to the ceiling panel 5, and a hanging member 4 connecting the main keel 2 and the secondary keel 3 so that the secondary keel 3 can move along the length direction of the main keel 2. The secondary keel 3 is provided with a splicing portion 31, and the ceiling panel 5 is plug-connected to the secondary keel 3 through the splicing portion 31.

[0032] In this embodiment, the suspension rod 1 is a through-thread suspension rod, one end of which is fixedly connected to the ceiling by an expansion screw, and the other end is fixedly connected to the main keel 2 by a nut 6. Specifically, the main keel 2 includes a top plate 21 provided with a plurality of connection holes 211, and the suspension rod 1 is inserted into the connection holes 211. The main keel 2 is clamped and fixed by respectively setting nuts 6 on both sides of the thickness direction of the top plate 21 and threadedly connected with the suspension rod 1 to complete the installation of the main keel 2. Among them, the installation height of the main keel 2 can be adjusted by changing the screwing position of the nut 6 on the suspension rod 1 to ensure the horizontality of the installation of the main keel 2 and realize the adjustment of the installation flatness of the ceiling board 5. During installation, first screw one of the nuts 6 onto the hanger 1 and roughly adjust it to the required screwing depth; then insert the hanger 1 into the connecting hole 211 of the main keel 2, and screw another nut 6 onto the hanger 1 at the same time, so that the top plate 21 is located between the two nuts 6, and a certain distance is left between the two nuts 6, so that the hanger 1 can move up and down within a certain range, leaving operating space for the installation of the hanger 1 and the ceiling; after completing the installation of the hanger 1 and the main keel 2, lift the main keel 2 as a whole, and fix the other end of the hanger 1 to the ceiling with an expansion screw; finally, fine-tune the screwing depth of the nut 6, and the installation of the hanger 1 and the main keel 2 is completed.

[0033] In this embodiment, if Figure 4 and 6As shown, the main keel 2 also includes a side plate 22 with a folded edge 221, and the hanging member 4 includes a first connecting portion 41 with a supporting plate 411, and the supporting plate 411 is in contact with the folded edge 221, so that the hanging member 4 is overlapped on the main keel 2; the side plate 22 also includes a first step edge 222 and a second step edge 223 arranged on both sides of the folded edge 221 in the horizontal direction, and the second step edge 223 is arranged obliquely. Specifically, the main keel 2 is integrally formed, including a horizontally arranged top plate 21, and two symmetrical side plates 22 arranged on the left and right sides of the top plate 21 in the horizontal direction, and the top plate 21 and the two side plates 22 together form the outer contour of the main keel 2; the hanging member 4 includes a first connecting portion 41 whose shape is adapted to the shape of the main keel 2, and the first connecting portion 41 can be directly sleeved on the outside of the main keel 2 and plug-connected with the main keel 2. Among them, the bending direction of the folded edge 221 of the side plate 22 is to bend toward the outside of the main keel 2, so that the top plate 21 is raised relative to the folded edge 221, so as to separate the installation area of ​​the suspension rod 1 and the main keel 2 from the installation area of ​​the hanging component 4 and the main keel 2 to avoid mutual interference; at the same time, when the hanging component 4 is sleeved on the main keel 2, the first step edge 222 can limit the support plate 411 to prevent the hanging component 4 from shaking left and right. In addition, the second step edge 223 is inclined, so that the main keel 2 is in a closed shape, which can absorb a certain installation error during assembly, that is, when the hanging component 4 cannot be completely fitted with the main keel 2, it will not affect the installation between the hanging component 4 and the main keel 2, reducing the installation accuracy and production accuracy requirements.

[0034] In this embodiment, if Figure 5-9 As shown, the hanging member 4 also includes a second connection part 42 plugged with the secondary keel 3, and the second connection part 42 is provided with a plug hole 421 penetrating the hanging member 4 along the cross-sectional direction of the hanging member 4, and the secondary keel 3 passes through the plug hole 421 and is movably connected with the hanging member 4. Among them, the second connection part 42 also includes a bottom plate 422 for supporting the secondary keel 3, and the bottom plate 422 is provided with an avoidance hole 4221, and the splicing part 31 extends out from the avoidance hole 4221 to be plugged with the ceiling plate 5. Specifically, the secondary keel 3 includes a main body 32 inserted into the plug hole 421, and a connecting plate 33 connecting the main body 32 and the splicing part 31. The connecting plate 33 extends to the left and right sides of the main body 32 to form an I-shaped structure with the splicing part 31. The plug hole 421 includes a square hole for the main body 32 to pass through, and a strip hole for the connecting plate 33 to pass through. The part of the connecting plate 33 inserted into the strip hole abuts against the bottom plate 422 to support the secondary keel 3. Figure 3 As shown, the connecting plate 33 is provided with a recessed portion 331, and the bottom plate 422 abuts against the recessed portion 331, so that when the secondary keel 3 and the hanging component 4 are plugged into each other, the lower surface of the bottom plate 422 and the lower surface of the connecting plate 33 can be located in the same plane, and abut against the surface of the ceiling panel 5 together, thereby increasing the flatness of the installation of the ceiling panel 5.

[0035] In this embodiment, the main keel 2 is inserted into the hanging member 4 along the length direction of the hanging member 4, and the secondary keel 3 is inserted into the hanging member 4 along the width direction of the hanging member 4, so that the main keel 2 and the secondary keel 3 are vertically connected to each other to form a keel frame structure; since the hanging member 4 is movably connected to the main keel 2, it can slide along the length direction of the main keel 2. When the hanging member 4 moves relative to the main keel 2, it can drive the secondary keel 3 to move together, so that the spacing between adjacent secondary keels 3 is adjustable to adapt to the splicing of ceiling panels 5 of different sizes, or to make room for the installation of electrical appliances, so that there is no need to cut or modify the main keel 2 or the secondary keel 3 when installing electrical appliances, and the installation is more flexible.

[0036] In this embodiment, if Figure 3 As shown, the ceiling plate 5 includes a joint surface 51 provided with a groove 511, and the joint portion 31 includes a plug-in board 311 inserted into the groove 511, and the end of the plug-in board 311 is provided with a protrusion 3111 that abuts against the inner surface of the groove 511. Specifically, since the thickness of the ceiling plate 5 and the width of the groove 511 are both small, errors are inevitable during processing and the uniformity of the size of the groove 511 cannot be guaranteed. Therefore, an arc-shaped protrusion 3111 is provided at the end of the plug-in board 311 to ensure that an interference fit can be formed when the plug-in board 311 is inserted into the groove 511, thereby ensuring the stability of the installation of the ceiling plate 5 and the plug-in board 311.

[0037] When installing a stepped ceiling, there is a height difference between the ceiling panels. The ceiling panels at the upper position need to be connected to the ceiling panels at the lower position through vertical panels. At this time, the keel often needs to be cut and changed to complete the installation. Figure 7 and 10 Specifically, the ceiling panel 5 includes a horizontal panel 52 and a vertical panel 53 which are arranged perpendicular to each other, the horizontal panels 52 are connected to each other through a splicing portion 31, the vertical panel 53 is placed on the horizontal panel 52, the secondary keel 3 is provided with an avoidance section 34 for avoiding the vertical panel 53, and the horizontal panel 52 is spliced ​​and connected while avoiding interference between the secondary keel 3 and the vertical panel 53, and the vertical panel 53 is placed on the horizontal panel 52 and abuts against the horizontal panel 52, and there is no need to perform a further edge trimming operation on the vertical panel 53.

[0038] The steps for installing a hanging assembly of a flat low-position ceiling of the present invention are as follows:

[0039] 1. Fix one end of the suspension rod 1 to the main keel 2 through the nut 6, and fix the other end to the ceiling through the expansion screw to complete the hanging installation of the main keel 2.

[0040] 2. Fine-tune the installation height of the main keel 2 by changing the screwing depth of the nut 6 on the suspension rod 1 to ensure the horizontality of the installation of the main keel 2.

[0041] 3. Insert the hanging member 4 along the length direction of the main keel 2 so that the first connecting portion 41 of the hanging member 4 is engaged with the main keel 2 , and roughly adjust the spacing between the hanging members 4 according to the size of the ceiling board 5 .

[0042] 4. Lift the secondary keel 3 and insert it into the insertion hole 421 of the hanging component 4 so that the secondary keel 3 is vertically connected to the main keel 2 .

[0043] 5. Lift the ceiling panel 5 and plug it into the joint part 31 of the secondary keel 3 to complete the assembly of the ceiling panel 5.
