[0002] Suspended ceiling is currently widely used in interior decoration. Its structure is mainly composed of keel system and ceiling.

[0003] The common suspended ceiling is an exposed ceiling, that is, the indoor personnel can see the keel structure, and the ceiling is placed on the keel through the erection edge. When installing and disassembling, the ceiling needs to be lifted to a certain height, and then the space between the keel and the roof of the building is used to tilt the ceiling so that the erection edge avoids the keel and can be removed.

[0004] However, in order to achieve the overall flatness of the ceiling, the ceiling technology is gradually developing towards large-area panels; at the same time, in order to gain a larger floor height, the space above the keel is getting smaller and smaller, which is not conducive to the installation and removal of the ceiling. If there are air vents, air ducts, water pipes and other building structures above the keel, it may even lead to the problem that the ceiling cannot be installed. At present, there is an urgent need for a more efficient and convenient ceiling installation structure.

It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of 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.

[0037] Embodiment 1

[0038] See also Figures 1 to 3 The embodiment of the present invention provides a pressing ceiling 2 installation structure, comprising a keel 1, a ceiling 2 and a pressing device 3; a baffle 4 is fixedly provided above the keel 1 and protrudes laterally from the keel 1; a mounting edge 5 protruding from the periphery of the ceiling 2 is provided on one side of the ceiling 2, and a pressing device 3 is installed on the side opposite to the mounting edge 5 and just below the baffle 4; the ceiling 2 is mounted on the keel 1 through the mounting edge 5 and the pressing device 3;

[0039] The pressing device 3 includes a base 6, a pressing block 7, a rotating piece 8 and a limiting member 9; a cylindrical sliding portion 10 is protruded from the middle of the base 6 installed on the ceiling 2, a through hole 11 is axially provided inside the sliding portion 10, and at least one slide groove 12 connecting the through hole 11 with the outside is axially provided on the outer wall of the through hole 11; a pressing head 13 is protruded from the top of the pressing block 7, and a trigger terminal 14 is protruded from the side of the pressing block 7, the pressing block 7 is slidably connected to the through hole 11, the pressing head 13 protrudes from the top of the sliding portion 10, the trigger terminal 14 is slidably connected to the slide groove 12 and radially protrudes outside the slide groove 12, and the bottom of the pressing block 7 is provided with a There is a spring (not shown); the rotating piece 8 is evenly distributed with multiple protruding pieces 15 protruding radially, a center hole is provided in the middle of the rotating piece 8, and multiple groups of trigger grooves 16 are evenly distributed on the inner wall of the center hole, each group of trigger grooves 16 is composed of a first spiral groove 17 and a second spiral groove 18 cross-connected in a V shape, and the ends of the first spiral groove 17 and the second spiral groove 18 extend and protrude to the same side, the center hole is rotatably sleeved on the periphery of the sliding part 10, and the trigger terminal 14 is embedded in the trigger groove 16, and the number of the trigger groove 16 is twice that of the protruding pieces 15; the limiting member 9 is fixedly installed on the sliding part 10, and is located above the rotating piece 8 to limit it.

[0040] The technical focus of the present invention lies in the structure of the pressing device 3. During installation, the pressing device 3 is in a retracted state, and the protruding piece 15 will not extend to interfere with the keel 1. First, the mounting edge 5 is hooked onto the keel 1 on one side, and then the side with the pressing device 3 is pressed upward, and the pressing device 3 is activated when it touches the baffle 4, and the protruding piece 15 extends and is mounted on the keel 1.

[0041] For details, please refer to Figure 4In order to more intuitively express the matching relationship between the trigger terminal 14 and the trigger slot 16, Figure 4 The inner wall of the rotating sheet 8 is expanded. The specific principle of the pressing device 3 is:

[0042] When the pressing head 13 of the pressing block 7 touches the baffle 4, the pressing block 7 will be pressed down along the through hole 11, and the trigger terminal 14 will also slide down along the slide groove 12. The trigger terminal 14 cooperates with the first spiral groove 17 and the second spiral groove 18. During the pressing process, the first spiral groove 17 forces the rotating piece 8 to rotate a certain angle. After releasing, the ceiling 2 is lowered again, and the pressing block 7 is also bounced up by the spring. The trigger terminal 14 enters the second spiral groove 18 and forces the rotating piece 8 to continue to rotate a certain angle in the same direction, completing a rotation action cycle. At this time, the protruding piece 15 changes from a contracted state to an extended state and is mounted on the keel 1. The first spiral groove 17 and the second spiral groove 18 are continuous with each other, and their ends extend a small section to the same side, which can ensure that each time the trigger terminal 14 moves to the end of the first spiral groove 17 or the second spiral groove 18, it will move a small section excessively, so that the pressing block 7 will definitely smoothly enter the next section of the spiral groove when it rebounds or is pressed next time.

[0043] As one preferred solution, the top periphery of the sliding part 10 is provided with an external thread, and the limiting member 9 is threadedly connected to the top of the sliding part 10 and is covered above the rotating piece 8. This installation method is relatively simple, but the external thread on the sliding part 10 is relatively difficult to process.

[0044] Or as another preferred solution, the sliding part 10 is provided with a limit groove above the rotating piece 8, and the limit member 9 is a retaining spring, which is clamped in the limit groove. The limit groove is easier to process than the external thread, and the retaining spring is a standard hardware part, which is easy to purchase in batches, but the installation is relatively difficult.

[0045] As a further preferred embodiment, a vertically extending positioning groove 19 is provided at the top connection of the first spiral groove 17 and the second spiral groove 18, and the positioning groove 19 is biased above the first spiral groove 17. Each time the pressing block 7 rebounds to the initial height, the trigger terminal 14 is stuck in the positioning groove 19, locking the rotating piece 8, and the state of the protruding piece 15 is completely fixed. This can prevent the protruding piece 15 from passively retracting, ensuring the installation reliability of the ceiling 2.

[0046] Furthermore, a safety rope (not shown) is connected between the ceiling 2 and the keel 1. The safety rope must be fastened first when installing the ceiling 2. Even if the pressing device 3 is loosened, the safety rope can still ensure that the ceiling 2 will not fall. This structure can ensure that the ceiling 2 will not fall due to misoperation or special airflow.

[0047] Embodiment 2

[0048] See also Figure 5 The only difference between this embodiment and the first embodiment is that the present embodiment is not directly mounted on the keel 1 through the protruding piece 15, but the protruding piece 15 drives the retractable telescopic edge 20, and the present embodiment is mounted on the keel 1 through the telescopic edge 20.

[0049] The specific plan is:

[0050] Preferably, it also includes a telescopic lap 20; the telescopic lap 20 is slidably connected to the side of the ceiling 2, and a spring (not shown) is provided between the telescopic lap 20 and the ceiling 2 to allow the telescopic lap 20 to elastically contract; the pressing device 3 is installed directly behind the telescopic lap 20.

[0051] When the protruding piece 15 extends, the telescopic lap 20 is pushed outward, and when the protruding piece 15 contracts, the telescopic lap 20 will elastically slide back under the action of the spring. Due to the structural characteristics of the pressing device 3, the protruding piece 15 cannot be made to be the same length as the side of the ceiling 2. If multiple sets of pressing devices 3 are set, on the one hand, the cost will be increased, and on the other hand, the operation will be more difficult. Moreover, the ceiling 2 with a large area is prone to slight bending due to insufficient material rigidity, and a mounting structure with the same length as the side is required to make up for the defects in the mechanical structure. Therefore, the telescopic lap 20 is more suitable for the mounting structure of the ceiling 2 with a large area.

[0052] Furthermore, the protruding piece 15 of the rotating piece 8 is arranged in an arc shape along one side of the rotating direction. In this embodiment, the rotating piece 8 actually functions as a cam structure, and the arc shape of the protruding piece 15 can reduce the resistance in the process of driving the telescopic overlap 20 .

[0053] The other technical features of this embodiment can all use the technical solutions of the first embodiment, and their structures and working principles are completely the same, so they will not be elaborated here.

[0054] The present invention provides a press ceiling 2 installation structure, which is innovatively provided with a press device 3. Through its unique design, the convex piece 15 is driven to extend or retract by a press operation mode, thereby realizing the installation of the ceiling 2. This not only greatly simplifies the installation operation of the ceiling 2, but also does not need to consider the space above the keel 1, which is conducive to increasing the area of ​​the ceiling 2 and increasing the height of the suspended ceiling. The installation structure has two options, and is provided with a safety rope to ensure safety.

[0055] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
