The following detailed description of the embodiments of the present invention will be made with reference to the accompanying drawings. It is to be understood that the description of the embodiments herein is for purposes of illustration and explanation only and is not intended to limit the invention.

An embodiment of the first aspect of the utility model provides a supporting component, as shown in fig. 1, including left socle 1 and right branch frame 2, left socle 1 and right branch frame 2 clearance fit to make the distance between left socle 1 and the right branch frame 2 adjustable, left socle 1 and right branch frame 2 are used for hanging decoration panel 3, and left socle 1 offers the first bit architecture 1111 and/or the first bit architecture 2111 of keeping away in the right side that is used for avoiding decorating the gypsum board of keeping away in a left side that is used for avoiding decorating the gypsum board and offers to be used for avoiding decorating the gypsum board with right branch frame 2.

Among the above-mentioned supporting component, including left socle 1 and right branch frame 2, adjust supporting component's size through the activity between left socle 1 and the right branch frame 2 to can adapt different size's decoration panel 3, need not be equipped with the supporting component of different specifications to different size's decoration panel 3, improve the availability factor, reduction in production cost. In addition, the left support 1 is provided with a left first avoidance structure 1111 and/or the right support 2 is provided with a right first avoidance structure 2111, so that the interference between the left support and/or the right support and the decorative gypsum board can be avoided, and the universality of the supporting assembly is improved.

The left bracket 1 and the right bracket 2 may be only fixedly connected to the rear wall, and since the decorative panel 3 needs to be supported by the left bracket 1 and the right bracket 2 when in use, the decorative panel needs to extend forward by a certain length in a direction away from the rear wall, so as to form a structure capable of supporting the decorative panel 3. Therefore, the left bracket 1 and the right bracket 2 are only fixedly connected with the rear wall, so that the parts of the left bracket 1 and the right bracket 2 extending forwards can be declined under the action of self gravity and the gravity of the smoke absorbing structure such as the decoration panel 3.

To ensure that the trim panel 3 can be suspended from the support assembly more stably, in some embodiments, the left bracket 1 and the right bracket 2 each have a first attachment location for attachment to a ceiling and a second attachment location for attachment to a rear wall. Above-mentioned two connection positions can carry on spacingly to two supports on vertical plane and horizontal plane, for only having the second connection position of being connected with the back wall, can effectively alleviate the problem that left socle 1 and right branch frame 2 have a down dip under the action of gravity, guarantee the stability of decoration panel 3 position, more pleasing to the eye.

It will be appreciated that the vertical plane is a plane parallel to the rear wall and the horizontal plane is a plane parallel to the suspended ceiling.
