[0025] As Figure 1-10 shown, in order to facilitate the understanding of the above technical solutions of the present utility model, the above technical solutions of the present utility model will be described in detail below through specific usage methods.

[0026] When in specific use, the quick-disassembly angle steel keel mechanism of the present utility model includes an n-shaped hanging member 2. A through wire suspension rod 3 is detachably connected to the top of the n-shaped hanging member 2. The bottom of the n-shaped hanging member 2 is provided with a bottom opening. On the left and right sides of the bottom opening of the n-shaped hanging member 2, there is an inner curled edge 201 each; the n-shaped hanging member 2 is penetrated from the front-back direction by an angle steel keel 1 with an L-shaped cross-section. The right side surface of the angle steel keel 1 is closely attached to the inner side of the right side wall of the n-shaped hanging member 2, and the bottom side surface of the angle steel keel 1 is closely attached to the two inner curled edges 201. The width of the bottom opening is less than the width of the bottom side surface of the angle steel keel 1.

[0027] In a certain embodiment, the right side surface of the angle steel keel 1 is further connected to the right side wall of the n-shaped hanging member 2 by a fixing screw 5.

[0028] In a certain embodiment, the fixing screw 5 penetrates through the right side wall of the n-shaped hanging member 2 and the right side surface of the angle steel keel 1 from right to left together.

[0029] In a certain embodiment, a limiting device 4 for fixing and limiting the angle steel keel 1 is further provided on the n-shaped hanging member 2.

[0030] In a certain embodiment, the limiting device 4 includes a limiting bolt 401 and an external nut 402 that cooperate with each other. The limiting bolt 401 penetrates through the n-shaped hanging member 2 from left to right. The right end of the limiting bolt 401 is threadedly connected to the external nut 402. The left end of the external nut 402 is closely attached to the outer side of the right side wall of the n-shaped hanging member 2.

[0031] In a certain embodiment, the limiting device 4 further includes an internal nut 403. The limiting bolt 401 is threadedly connected to the internal nut 403. The top end of the right side surface of the angle steel keel 1 is clamped between the right end of the internal nut 403 and the inner side of the right side wall of the n-shaped hanging member 2.

[0032] In a certain embodiment, the limiting device 4 further includes a sleeve 404. The sleeve 404 is sleeved on the limiting bolt 401. The left end of the sleeve 404 is closely attached to the inner side of the left side wall of the n-shaped hanging member 2. The top end of the right side surface of the angle steel keel 1 is clamped between the right end of the sleeve 404 and the inner side of the right side wall of the n-shaped hanging member 2.

[0033] In a certain embodiment, the sleeve 404 is preferably a steel sleeve.

[0034] In a certain embodiment, the left and right ends of the bottom side of the angle steel keel 1 are respectively in close contact with the left and right side walls of the n-shaped hanging member 2.

[0035] In a certain embodiment, the through wire hanger rod 3 includes a hanger bolt 301. The screw rod of the hanger bolt 301 passes upward through the top side wall of the n-shaped hanging member 2 and is threadedly connected to a hanger nut 302. The nut of the hanger bolt 301 and the hanger nut 302 jointly clamp the top side wall of the n-shaped hanging member 2 in the middle.

[0036] Working principle: This product can adopt the idea of prefabricated assembly. The through wire hanger rod 3 is not directly connected to the angle steel keel 1 for ceiling. Instead, an n-shaped hanging member 2 with an inward curling edge is provided below the through wire hanger rod 3, and the through wire hanger rod 3 and the n-shaped hanging member 2 are connected by nuts. The bottom position of the n-shaped hanging member 2 is leveled according to the ceiling elevation with a string.

[0037] The angle steel keel 1 is obliquely inserted upward through the opening between the two inward curling edges of the n-shaped hanging member 2 by adjusting the angle. After the angle steel keel 1 is placed between the two inward curling edges of the n-shaped hanging member 2, it is placed on the two inward curling edges of the n-shaped hanging member 2 by adjusting the angle and position of the angle steel keel 1. After the limit bolt 4 is installed, the angle steel keel 1 cannot move or rotate up, down, left or right on the n-shaped hanging member 2. Then, the fixing screw 5 is screwed into the angle steel keel 1 from the n-shaped hanging member 2, completely restricting the front and back movement of the angle steel keel 1. The installation of the angle steel keel 1 is completed.

[0038] When disassembly is required, only the fixing screw 5 and the limit bolt 4 need to be removed. Then rotate the angle steel keel 1 and remove the angle steel keel 1 from the lower opening of the n-shaped hanging member 2. The entire installation and disassembly process is very fast and easy, which is a truly fast and easy disassembly angle steel keel system.

[0039] Construction steps: As Figure 1-3 shown, the fast and easy disassembly angle steel keel mechanism includes an angle steel keel 1, an n-shaped hanging member 2, a through wire hanger rod 3, a limit bolt 4, a fixing screw 5, etc. During specific construction, as Figures 4 to 7 shown, by using the characteristic that the L-shaped cross-section of the angle steel keel 1 can be placed in the n-shaped hanging member 2 with an opening smaller than the width of the angle steel keel 1 by adjusting the angle, the angle steel keel 1 is placed in the n-shaped hanging member 2 by adjusting the angle of the angle steel keel 1, and then the vertical side of the angle steel keel 1 is pressed by the limit bolt 4, so that the angle steel keel cannot rotate or displace in the n-shaped hanging member 2 with inward curling edges. The fixing screw 5 is screwed into the angle steel keel 1 to fix the keel and the hanging member, completing the installation of the ceiling keel system. The installation process is introduced as follows:

[0040] The first step: Adjust the direction of the angle steel keel 1 and insert it into the n-shaped hanging member 2 with inward curling edges to reach the keel position shown in "Step 2", as Figure 4 shown in "Step 1".

[0041] Step 2: Rotate the angle steel keel 1 along side A until it reaches the keel position shown in "Step 3", as shown in Figure 4 "Step 2".

[0042] Step 3: Lift the angle steel keel 1 so that it entirely enters the inner-rolled edge n-shaped hanger 2 and reaches the keel position shown in "Step 4", as shown in Figure 5 "Step 3".

[0043] Step 4: Rotate the angle steel keel 1 along side A until it reaches the keel position shown in "Step 5", as shown in Figure 5 "Step 4".

[0044] Step 5: Rotate the angle steel keel 1 along side B until it reaches the keel position shown in "Step 6", as shown in Figure 6 "Step 5".

[0045] Step 6: Fine-tune the position of the angle steel keel 1, as shown in Figure 6 "Step 6".

[0046] Step 7: Screw the limit bolt 4 into the inner-rolled edge n-shaped hanger 2 to tightly press against side A of the angle steel keel 1, so that the angle steel keel 1 cannot rotate or displace within the space enclosed by the inner-rolled edge 201 and the n-shaped hanger 2. As shown in Figure 7 "Step 7".

[0047] Step 8: Screw the fixing screw 5 into the inner-rolled edge n-shaped hanger 2 and the angle steel keel 1 to fix the keel and the hanger, completing the installation of the quick-disassembly angle steel keel mechanism. As shown in Figure 7 "Step 8".

[0048] Figure 8 and Figure 9 and Figure 10 are the physical installation effect diagrams of the inner-rolled edge 201, the n-shaped hanger 2, and the quick-disassembly angle steel keel mechanism, from which the positional relationships of the n-shaped hanger 2, the angle steel keel 1, etc. can be visually seen.

[0049] In summary, the product adopts the above unique design. The product has a simple structure, is easy to operate, and is very convenient for installation and disassembly. The product can not only adopt the prefabricated assembly concept, where the suspender is not directly connected to the ceiling keel, and the bottom side wall position of the n-shaped hanger is leveled according to the ceiling elevation line, thus achieving simple and quick leveling; but also when adjusting along the length direction of the angle steel keel, it is not necessary to remove the angle steel keel and refix it.

[0050] In the description of the present utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
