Referring to fig. 5 and 6, unlike embodiment 1, each set of second connecting mechanisms 4 includes two sets of first snap assemblies 47 and two sets of second snap assemblies 48, the first snap assemblies 47 and the second snap assemblies 48 can cooperate with each other, and the first snap assemblies 47 include first fixing blocks 471, first abutting blocks 472 and first torsion springs 473. First fixed block 471 passes through the bolt fastening in the interior diapire of false keel 22, and first fixed block 471 is vertical setting, and first piece 472 that supports is provided with two, and first piece 472 one end that supports is rotated and is connected in first fixed block 471 upper end. The first torsion spring 473 is fixed between the first fixing block 471 and the first abutting block 472, and limits one end of the first abutting block 472, which is far away from the first fixing block 471, to rotate upward, and in the initial state, the first abutting block 472 is horizontally disposed.

Referring to fig. 6 and 7, the second buckle assembly 48 includes a second fixing block 481, a second abutting block 482 and a second torsion spring 483, the second fixing block 481 is provided with two, the upper end of the second fixing block 481 is fixed to the side wall of the main keel 21 vertically along the length direction thereof through a bolt, the second abutting block 482 is provided with two, and one end of the second abutting block 482 is rotatably connected to the lower end of the second fixing block 481. The second torsion spring 483 is fixed between the second fixing block 481 and the second abutting block 482, and defines the second abutting block 482 to rotate downward, and in an initial state, the second abutting block 482 is horizontally disposed.

Referring to fig. 7, a sliding groove 49 is formed in a side wall of the second fixing block 481 provided with the second abutting block 482, the lower end of the sliding groove 49 penetrates through the second fixing block 481, and the first fixing block 471 is connected to the side wall where the sliding groove 49 is located in a sliding manner.

Referring to fig. 7, when the cross runner 22 is installed on the main runner 21, the first abutting block 472 and the second abutting block 482 contact with each other, then the first abutting block 472 rotates downward, the second abutting block 482 rotates upward, at this time, the cross runner 22 continues to move toward the main runner 21 until the first abutting block 472 is separated from the second abutting block 482, then the first abutting block 472 and the second abutting block 482 both return to a horizontal state, so that the lower surface of the first abutting block 472 abuts against the upper surface of the second abutting block 482, and the cross runner 22 is fixed on the main runner 21.

Referring to fig. 7, in order to increase the stability of the first abutting block 472 and the second abutting block 482, a first rotation limiting block 475 is fixed to a side wall of the first fixing block 471 through a bolt, and the first rotation limiting block 475 is located above the first abutting block 472 and is used for abutting against the first abutting block 472, so that the first abutting block 472 is prevented from rotating upwards. The side wall of the second fixing block 481 is fixed with a second rotation limiting block 484 through a bolt, and the second rotation limiting block 484 is located below the second abutting block 482 and used for abutting against the second abutting block 482 so as to prevent the second abutting block 482 from rotating downwards.

Referring to fig. 7, the lower surface of the first abutting block 472 is further integrally formed with a positioning block 474, the upper surface of the second abutting block 482 is provided with a positioning groove 485, and the positioning block 474 is in insertion fit with the positioning groove 485. When the lower surface of the first abutting block 472 abuts against the upper surface of the second abutting block 482, the positioning block 474 is located in the positioning groove 485, so that the relative positions of the main keel 21 and the cross keel 22 can be defined.

The implementation principle of the suspended ceiling is decorated to a quick type in this application embodiment does: when installing the false keel 22 to the main joist 21, first piece 472 and the second piece 482 that supports contact each other supports, and first piece 472 that supports subsequently rotates down, and the second piece 482 that supports rotates up, and the false keel 22 continues to move towards the main joist 21 this moment, and until first piece 472 and the second piece 482 that supports separate, first piece 472 that supports subsequently supports and the second piece 482 that supports all resumes to the horizontality, thereby first piece 472 lower surface that supports abuts in the upper surface of the second piece 482 that supports, makes the false keel 22 be fixed in on the main joist 21.

A quick installation method of a decorative suspended ceiling comprises the following steps:

s1, providing a plurality of suspension rods 1, a plurality of main keels 21 and a plurality of auxiliary keels 22, and installing the first connecting mechanism 3 at the lower end of the suspension rods 1;

s2, arranging a plurality of threaded holes in parallel on a ceiling, wherein the distance between every two adjacent threaded holes in each row is 700mm, the distance between every two adjacent threaded holes in each row is 300mm, screwing the upper end of the suspender 1 into the threaded holes, exposing the lower end of the suspender 1 out of the ceiling, and ensuring that the distance between the lower end of the suspender 1 and the ceiling is 400 mm;

s3: moving the main keel 21 from bottom to top to enable the upper surface of the main keel 21 to push the limiting block 32 and enable the limiting block 32 to compress the first spring 31, wherein in the upward moving process of the limiting block 32, the ejector rod 36 is separated from the positioning hole 341, the third spring 42 restores to the initial state and pushes the supporting block 34 to enable the supporting block 34 to be located under the limiting block 32, then the main keel 21 stops moving, the limiting block 32 abuts against the upper surface of the main keel 21, and the supporting block 34 abuts against the lower surface of the main keel 21;

s4: install many trigger bars 41 in main joist 21 lower surface through the bolt, and many trigger bars 41 arrange along main joist 21 lower surface, again with mounting 44, butt strip 43, third spring 42, hang component 45 and install in false keel 22, adjust false keel 22 position, the interval is 350mm between the adjacent false keel 22, make false keel 22 length direction be horizontal setting, and false keel 22 length direction is on a parallel with main joist 21 length direction, remove false keel 22 towards main joist 21 direction afterwards, make grafting portion 441 peg graft in through-hole 212, horizontal portion lower surface butt in main joist 21 inner chamber diapire, install the furred ceiling board on false keel 22, accomplish the installation.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
