Description

Technical Field

[0001] This utility model relates to the field of ceiling keel frame technology, and in particular to a ceiling modular keel frame. Background Technology

[0002] The ceiling keel frame is used to install and suspend decorative materials such as gypsum board. The ceiling keel frame consists of hangers, hangers, nuts, washers, main keel, hangers, bolts, and secondary keels. When using the ceiling keel frame, the hangers are fixed to the indoor ceiling. Then, the hangers are fixed to the hangers by using nuts and washers. Next, the main keel is placed into the hangers and the hangers are tightened with bolts to fix the main keel. Then, the secondary keels are slidably installed onto the hangers, thus completing the keel frame assembly. Finally, the gypsum board is fixed to the secondary keel with screws, thus installing and suspending the gypsum board.

[0003] The inventor discovered in daily work that when using the ceiling keel frame, workers need to lift the plasterboard to align the mounting holes on the plasterboard with the mounting holes on the secondary keel before screwing in the screws. Because workers lift the plasterboard for a long time, their arms easily become sore, which may cause the plasterboard to wobble and the mounting holes to become misaligned, requiring realignment and potentially affecting the efficiency of installing the plasterboard onto the secondary keel. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in actual use, when fixing gypsum board to the secondary keel, workers need to hold up the gypsum board to keep the mounting holes on the gypsum board aligned with the mounting holes on the secondary keel before screwing in the screws for fixing. However, due to the long-term holding, the workers' arms are prone to fatigue, which may cause the gypsum board to shake and the mounting holes to misalign, thus requiring realignment and installation, which may affect the efficiency of installing gypsum board to the secondary keel. Therefore, a ceiling modular keel frame is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a ceiling-mounted modular keel frame, comprising a suspension rod, a hanging member provided on the arc surface of the suspension rod, a nut threadedly connected to the arc surface of the suspension rod, a bolt provided on the front side of the hanging member, a main keel provided on the inner wall of the hanging member, a hanger fixedly connected to the lower end of the main keel, a secondary keel slidably connected to the surface of the hanger, a pre-fixing component provided at the lower end of the secondary keel, a limiting component provided on the front side of the hanger, the pre-fixing component comprising a fixing ring fixedly connected to the lower end of the secondary keel, a plurality of evenly distributed inserts slidably inserted on the arc surface of the fixing ring, and a sliding surface provided on the left end of the insert.

[0006] The effect achieved by the above-mentioned components is as follows: By setting up the pre-fixing components, when installing and fixing the gypsum board to the secondary keel, the worker lifts the gypsum board so that the fixing ring is inserted into the gypsum board, and the insert is inserted into the gypsum board by means of the sliding surface. After the fixing ring is fully inserted into the gypsum board, the reset mechanism is used to insert the insert into the gypsum board, thereby pre-fixing the gypsum board. Then the worker no longer needs to lift the gypsum board. Then the screw is tightened to fix the gypsum board to the fixing ring thread, thereby fixing the gypsum board, thereby maximizing the efficiency of installing the gypsum board to the secondary keel.

[0007] Preferably, a spring is fixedly connected to the right end of the insert block, and the other end of the spring is fixed to a retaining ring.

[0008] The effect achieved by the above components is as follows: when the insert is inserted into the plasterboard, the spring is in a compressed state. After the fixing ring is fully inserted into the plasterboard, the spring deforms and returns to its original state, driving the pin to move so that the insert is inserted into the plasterboard.

[0009] Preferably, a pull rope is fixedly connected to the right end of the insert block, and the pull rope passes through the fixing ring and the secondary keel.

[0010] The effect achieved by the above components is that pulling the pull rope causes the insert to retract completely into the fixing ring, thereby dragging the plasterboard to separate.

[0011] Preferably, the inner wall of the secondary keel is slidably connected with a slip ring, and the slip ring is fixed to the pull rope.

[0012] The effect achieved by the above components is to pull the slip ring, thereby pulling the rope.

[0013] Preferably, the limiting component includes rectangular grooves formed on both sides of the hanger, and rectangular blocks are slidably connected to the inner walls of the rectangular grooves, with the rectangular blocks penetrating the secondary keel.

[0014] The effect achieved by the above components is that when fixing the secondary keel and the hanger, the rectangular block in the rectangular groove is inserted into the secondary keel by the pushing mechanism, thereby fixing the secondary keel and the hanger.

[0015] Preferably, a first piston is provided on the inner wall of the rectangular groove, the first piston is fixed to the rectangular block, and a T-shaped groove communicating with the rectangular groove is opened inside the hanging part, and a second piston is provided on the inner wall of the T-shaped groove.

[0016] The effect achieved by the above components is as follows: by setting the first piston and the second piston and the T-shaped groove, the two pistons are in a closed state. When the second piston is pushed, the first piston is pushed, so that the rectangular block in the rectangular groove is inserted into the secondary keel.

[0017] Preferably, a screw is rotatably connected to the front of the second piston, and the screw is threadedly connected to the hanger.

[0018] The effect achieved by the above components is that when the worker turns the screw, the second piston is pushed.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] In this invention, by setting a pre-fixing component, when installing and fixing the plasterboard to the secondary keel, the worker lifts the plasterboard so that the fixing ring is inserted into the plasterboard, and the insert block enters into the plasterboard with the help of the sliding surface. After the fixing ring is fully inserted into the plasterboard, the reset mechanism inserts the insert block into the plasterboard, thus pre-fixing the plasterboard. Then, the worker no longer needs to lift the plasterboard. Then, the plasterboard is fixed by tightening the screws and fixing the screw threads. This improves the efficiency of installing the plasterboard to the secondary keel as much as possible. It solves the problem that when fixing the plasterboard to the secondary keel, the worker needs to lift the plasterboard, keep the mounting holes on the plasterboard aligned with the mounting holes on the secondary keel, and then tighten the screws for fixing. Because the worker's arm is prone to fatigue from lifting for a long time, the plasterboard may shake, causing the mounting holes to misalign, requiring realignment and installation, which may affect the efficiency of installing the plasterboard to the secondary keel.

[0026] Reference Figure 1As shown, this utility model provides a technical solution: a ceiling-mounted modular keel frame includes a suspension rod 1, a hanging member 4 is provided on the arc surface of the suspension rod 1, a nut 5 is threadedly connected to the arc surface of the suspension rod 1, a bolt 6 is provided on the front of the hanging member 4, a main keel 7 is provided on the inner wall of the hanging member 4, a hanging member 9 is fixedly connected to the lower end of the main keel 7, a secondary keel 8 is slidably connected to the surface of the hanging member 9, a pre-fixing component 2 is provided at the lower end of the secondary keel 8, and a limiting component 3 is provided on the front of the hanging member 9.

[0027] The specific settings and functions of the pre-fixed component 2 and the limiting component 3 will be explained in detail below.

[0028] Reference Figure 2 and Figure 3 As shown in this embodiment: the pre-fixing component 2 includes a fixing ring 21 fixedly connected to the lower end of the secondary keel 8. Multiple evenly distributed inserts 23 are slidably inserted into the arc surface of the fixing ring 21. A sliding surface 24 is provided at the left end of each insert 23. By setting the pre-fixing component 2, when installing the plasterboard onto the secondary keel 8, the worker lifts the plasterboard, causing the fixing ring 21 to insert into the plasterboard. The inserts 23 then enter the plasterboard using the sliding surface 24. After the fixing ring 21 is fully inserted into the plasterboard, a reset mechanism inserts the inserts 23 into the plasterboard, thus pre-fixing the plasterboard. Then, the worker no longer needs to lift the plasterboard. The plasterboard is then fixed by tightening screws to the fixing ring 21, thereby achieving the desired fixation. To improve the efficiency of installing gypsum board onto the secondary keel 8, a spring 25 is fixedly connected to the right end of the insert 23. The other end of the spring 25 is fixed to the fixing ring 21. When the insert 23 is inserted into the gypsum board, the spring 25 is in a compressed state. After the fixing ring 21 is fully inserted into the gypsum board, the spring 25 returns to its original shape, causing the pin to move and allowing the insert 23 to be inserted into the gypsum board. A pull rope 26 is fixedly connected to the right end of the insert 23. The pull rope 26 passes through the fixing ring 21 and the secondary keel 8. Pulling the pull rope 26 causes the insert 23 to retract completely into the fixing ring 21, thereby dragging the gypsum board to separate. A sliding ring 27 is slidably connected to the inner wall of the secondary keel 8. The sliding ring 27 is fixed to the pull rope 26. Pulling the sliding ring 27 causes the pull rope 26 to be pulled.

[0029] Reference Figure 4As shown, in this embodiment: the limiting component 3 includes rectangular grooves 31 formed on both sides of the hanger 9. A rectangular block 32 is slidably connected to the inner wall of the rectangular groove 31, and the rectangular block 32 penetrates the secondary keel 8. When fixing the secondary keel 8 and the hanger 9, a pushing mechanism causes the rectangular block 32 in the rectangular groove 31 to insert into the secondary keel 8, thereby fixing the secondary keel 8 and the hanger 9. A first piston 33 is provided on the inner wall of the rectangular groove 31, and the first piston 33 is fixed to the rectangular block 32. The hanger 9 has an opening inside that corresponds to the rectangular groove. The T-shaped groove 34 is connected to 31. The inner wall of the T-shaped groove 34 is provided with a second piston 35. By setting the first piston 33, the second piston 35 and the T-shaped groove 34, the two pistons are in a closed state. When the second piston 35 is pushed, the first piston 33 is pushed, so that the rectangular block 32 in the rectangular groove 31 is inserted into the secondary keel 8. The front of the second piston 35 is rotatably connected to a screw 36. The screw 36 is threadedly connected to the hanger 9. When the worker turns the screw 36, the second piston 35 is pushed.

[0030] Working principle:

[0031] When using the ceiling keel frame, fix the hanger rod 1 to the indoor ceiling, then fix the hanger 4 to the hanger rod 1 using nuts 5 and washers. Next, place the main keel 7 into the hanger 4 and tighten the hanger 4 with bolts 6 to fix the main keel 7. Then, slide the secondary keel 8 onto the hanger 9 to complete the keel frame assembly. Next, fix the plasterboard to the secondary keel 8 with screws to install the hanging plasterboard. When installing and fixing the plasterboard to the secondary keel 8, the worker lifts the plasterboard so that the fixing ring 21 is inserted into the plasterboard, and the insert 23 enters into the plasterboard with the help of the sliding surface 24. The spring 25 is in a compressed state. After the fixing ring 21 is fully inserted into the plasterboard, the spring 25 returns to its original shape, driving the pin to move, so that the insert 23 is inserted. The plasterboard is inserted into the gypsum board, thus pre-fixing the gypsum board. Then, the worker no longer needs to lift the gypsum board. Next, the gypsum board is fixed by tightening the screws and fixing ring 21, thereby maximizing the efficiency of installing the gypsum board onto the secondary keel 8. Pulling the slip ring 27 causes the pull rope 26 to be pulled, causing the insert block 23 to fully retract into the fixing ring 21, thereby dragging the gypsum board to separate. When fixing the secondary keel 8 and the hanger 9, the first piston 33 and the second piston 35, as well as the T-shaped groove 34, are set to keep the two pistons in a closed state. The worker tightens the screw 36, causing the second piston 35 to be pushed, causing the rectangular block 32 in the rectangular groove 31 to be inserted into the secondary keel 8, thereby fixing the secondary keel 8 and the hanger 9.
