[0029] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0030] Embodiment 1:

[0031] like Figure 1-5 As shown, a building decorative ceiling includes a plurality of aluminum gusset plates 1, a secondary keel 2, a main keel 3 and a suspension rod 4.

[0032] The top of the aluminum gusset plate 1 is movably mounted on the bottom of the secondary keel 2 through multiple groups of connecting parts 10. A plurality of fixed tubes 11 symmetrically arranged in pairs are fixedly mounted on the lower surface of the top of the secondary keel 2. The connecting part 10 includes an insert rod 15 and a spring 17. A spring 12 is buckled on the lower surface of the top of the fixed tube 11. A slip ring 13 is buckled on the other end of the spring 12. The slip ring 13 is slidably fitted on the inner wall of the fixed tube 11, and a fixing ring 14 is fixedly connected to the inner wall of the fixed tube 11 located at the bottom of the spring 12. One end of the insert rod 15 is fixedly connected to the top of the aluminum gusset plate 1, and the other end of the insert rod 15 is movably inserted into the inner wall of the fixed tube 11. The inner wall of the insert rod 15 is rotatably connected to two symmetrically arranged limit rods 16. The other end of the limit rod 16 is movably limited and fitted on the top of the fixing ring 14. The spring 17 is buckled on the opposite sides of the two limit rods 16.

[0033] When it is necessary to install the aluminum gusset plate 1 and the secondary keel 2, align the insertion rod 15 with the fixing tube 11 and then insert it into the fixing tube 11. Due to the limitation of the fixing ring 14, the two limiting rods 16 are squeezed and retracted into the insertion rod 15, and the spring 17 is compressed. When the limiting rod 16 passes over the fixing ring 14, the limiting rod 16 is no longer restricted and opens to both sides under the elastic action of the spring 17. The fixing ring 14 and the limiting rod 16 cooperate to make the insertion rod 15 stuck in the fixing tube 11, thereby completing the installation of an aluminum gusset plate 1; when it is necessary to remove the aluminum gusset plate 1, push the aluminum gusset plate 1 upward to make the insertion rod 15 move to the top of the fixing tube 11. During the upward movement of the insertion rod 15, the limiting rod 16 is limited by the slip ring 13 and retracted into the insertion rod 15, and the slip ring 13 and the limiting rod 1 After the aluminum gusset plate 1 is lowered, although the limit rod 16 is pushed into the insert rod 15 by the slip ring 13, the elastic force of the spring 17 makes the limit rod 16 still rest against the inner wall of the slip ring 13, so that when the aluminum gusset plate 1 is lowered, the slip ring 13 is driven to move downward at the same time until the slip ring 13 contacts the fixing ring 14. At this time, there is no distance between the slip ring 13 and the fixing ring 14, and the limit rod 16 is not blocked and smoothly detaches from the fixing tube 11. After the aluminum gusset plate 1 is detached, the slip ring 13 is reset under the elastic action of the spring 12 to prepare for the next installation.

[0034] The device sets a slip ring 13, a fixed ring 14, an insertion rod 15 and a limit rod 16, and uses the distance between the slip ring 13 and the fixed ring 14 to limit the limit rod 16, so as to quickly complete the installation of the aluminum gusset plate 1 and the secondary keel 2. When the aluminum gusset plate 1 is pushed again, the spring 12 and the slip ring 13 are used to release the limit on the limit rod 16 and the insertion rod 15, so that the aluminum gusset plate 1 can be quickly disassembled, thereby improving the installation and disassembly efficiency of the aluminum gusset plate 1.

[0035] like Figure 1 and Figure 2 The top end of the suspension rod 4 is fixed to the ceiling by an expansion bolt 5 .

[0036] The bottom end of the suspension rod 4 is fixedly connected with a suspension piece 1 6 by bolts, the outer wall of the secondary keel 2 is buckled with a suspension piece 2 9 , and the main keel 3 is clamped on the bottom upper surface of the suspension piece 1 6 and on the top lower surface of the suspension piece 2 9 .

[0037] First, determine the installation position of the hanger 4 and drill a hole in the ceiling to ensure that the diameter of the hole matches the size of the expansion bolt 5. Then, insert the expansion bolt 5 into the hole to ensure that the expansion sleeve is in the hole. Use a wrench or a wrench socket or other tools to rotate the head of the expansion bolt 5 so that the expansion sleeve at the bottom of the expansion bolt 5 will expand. When the expansion bolt 5 is fully tightened, the expansion sleeve will fill the hole and be tightly fixed to the hole wall. Then, place the connecting part of the hanger 4 on the top of the expansion bolt 5 and fix it to the bolt with a nut. Subsequently, use the bolt to install the hanging piece 1 6 on the bottom end of the hanger 4, and insert the main keel 3 into the bottom upper surface of the hanging piece 1 6. Then, after inserting the secondary keel 2 into the hanging piece 2 9, insert the top upper surface of the hanging piece 2 9 into the outer wall of the main keel 3. At this point, the connection and installation of the secondary keel 2, the main keel 3 and the hanger 4 are completed.

[0038] Embodiment 2:

[0039] A building decoration ceiling, this embodiment makes the following improvements on the basis of embodiment 1, such as Figure 2 , Figure 4 and Figure 5 As shown:

[0040] The top and bottom of the main keel 3 are provided with a plurality of avoidance grooves 8 , and each avoidance groove 8 is provided with two sets of connecting members 7 .

[0041] One group of the connecting parts 7 is used for connecting and fixing the main keel 3 and the hanging piece 6, and the other group of the connecting parts 7 is used for connecting and fixing the main keel 3 and the hanging piece 2 9.

[0042] The connecting member 7 includes a limit plate 18, a second plug rod 19 and a third spring 20. The limit plate 18 is fixedly connected to the inner wall of the main keel 3, the second plug rod 19 is slidably fitted on the inner wall of the limit plate 18, and the third spring 20 is buckled on the opposite side of the second plug rod 19 and the main keel 3.

[0043] The outer wall of the second insertion rod 19 is rotatably connected to two symmetrically arranged connecting rods 21, and the other end of the connecting rod 21 is rotatably connected to a limiting rod 22. The main keel 3, the first hanging piece 6 and the inner wall of the second hanging piece 9 are all provided with limiting grooves adapted to the limiting rod 22, and the limiting rod 22 is movably inserted in the limiting groove.

[0044] In this embodiment: the connection between the main keel 3 and the hanging piece 6 is the same as the connection between the main keel 3 and the hanging piece 2 9. Take the connection between the main keel 3 and the hanging piece 6 as an example: when the main keel 3 needs to be inserted into the hanging piece 6, it is necessary to pull the insertion rod 2 19 first so that the spring 3 20 is stretched. At the same time, the insertion rod 21 drives the limiting rod 22 to slide until its end is flush with the outer surface of the main keel 3. At this time, the main keel 3 can be smoothly inserted into the hanging piece 6, and then the insertion rod 29 is released. The spring 3 20 uses its own elasticity to drive the insertion rod 19 to reset, so that the limiting rod 22 can be inserted into the limiting grooves of the main keel 3 and the hanging piece 6 at the same time, so that the limiting rod 22 limits and fixes the main keel 3 and the hanging piece 6.

[0045] The device is provided with an insert rod 2 19, a connecting rod 21 and a limit rod 22, and uses the limit rod 22 to limit and fix the main keel 3, the hanging piece 1 6 and the hanging piece 2 9. Compared with the traditional bolt connection, the efficiency of installation and connection is greatly improved, and the disassembly is more convenient, thereby improving the convenience of use of the device.

[0046] Working principle: When installing the suspended ceiling, first determine the installation position of each suspension rod 4 according to the needs, then drill holes in the ceiling, make sure that the diameter of the hole matches the size of the expansion bolt 5, then insert the expansion bolt 5 into the hole, make sure that the expansion sleeve is in the hole, use a wrench or wrench socket and other tools to rotate the head of the expansion bolt 5, so that the expansion sleeve at the bottom of the expansion bolt 5 will expand, when the expansion bolt 5 is fully tightened, the expansion sleeve will fill the hole and be tightly fixed on the hole wall, then, the connecting part of the suspension rod 4 Place it on the top of the expansion bolt and use a nut to fix it on the bolt, then use the bolt to install the hanging piece 6 on the bottom end of the hanger 4, and insert the main keel 3 into the upper surface of the bottom of the hanging piece 6, then insert the secondary keel 2 into the hanging piece 2 9, the main keel 3 and the hanging piece 6 are connected, and the hanging piece 2 9 and the main keel 3 are connected in the same way. Take the connection between the main keel 3 and the hanging piece 6 as an example: when the main keel 3 needs to be inserted into the hanging piece 6, it is necessary to pull the plug rod 2 19 first, so that the spring 3 20 is stretched, and the plug rod 2 19 is used The connecting rod 21 drives the limiting rod 22 to slide until its end is flush with the outer surface of the main keel 3. At this time, the main keel 3 can be smoothly inserted into the hanging piece 6, and then the insertion rod 219 is released. The spring 320 uses its own elasticity to drive the insertion rod 219 to reset, so that the limiting rod 22 can be inserted into the limiting grooves of the main keel 3 and the hanging piece 6 at the same time, so that the limiting rod 22 limits and fixes the main keel 3 and the hanging piece 6, thereby completing the connection between the main keel 3 and the hanging piece 6, and the connection between the hanging piece 29 and the main keel 3, and finally the aluminum gusset plate 1 is connected. Installation with the secondary keel 2: Align the insertion rod 15 with the fixing tube 11 and insert it into the fixing tube 11. Due to the limitation of the fixing ring 14, the two limiting rods 16 are squeezed into the insertion rod 15, and the spring 2 17 is compressed. When the limiting rod 16 passes over the fixing ring 14, the limiting rod 16 is no longer limited and opens to both sides under the elastic action of the spring 2 17. The fixing ring 14 and the limiting rod 16 cooperate to make the insertion rod 15 stuck in the fixing tube 11, thereby completing the installation of an aluminum gusset plate 1;When the aluminum gusset plate 1 needs to be removed, the aluminum gusset plate 1 is pushed upward to move the insertion rod 15 toward the top of the fixed tube 11. During the upward movement of the insertion rod 15, the limiting rod 16 is limited by the slip ring 13 and retracted into the insertion rod 15. After the slip ring 13 contacts the limiting rod 16, it is also driven by the limiting rod 16 to slide upward for a distance, so that the spring 12 is compressed. When the insertion rod 15 reaches the top of the fixed tube 11 and cannot continue to rise, stop pushing the aluminum gusset plate 1 and gently release the support for the aluminum gusset plate 1 to allow it to fall naturally. During the descent of the aluminum gusset plate 1, although the limit rod 16 is pushed into the insertion rod 15 by the slip ring 13, the elastic force of the spring 2 17 makes the limit rod 16 still against the inner wall of the slip ring 13, so that when the aluminum gusset plate 1 is descended, the slip ring 13 is driven to move downward at the same time until the slip ring 13 contacts the fixed ring 14. At this time, there is no gap between the slip ring 13 and the fixed ring 14, and the limit rod 16 is not blocked and smoothly detaches from the fixed cylinder 11. After the aluminum gusset plate 1 is detached, the slip ring 13 is reset under the elastic action of the spring 12 to prepare for the next installation. ;

[0047] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
