The decorative frame 2 can be well integrated with the grille 1, and the overall appearance is good. The setting of the upper sprinkler head 6 and the lower sprinkler head 7 ensures that the fire protection requirements are met. Secondly, the height-adjustable bracket 4 facilitates the installation of the sprinkler pipe 3.

[0026] One embodiment of the hanger 4: The hanger 4 includes: an upper support 41, a connector 42, a lower support 43, a locking screw 44, and a fixing plate 45. The connector 42 is located between the upper support 41 and the lower support 43. The upper support 41 is fixed to the top plate 5, and the spray pipe 3 is fixed to the lower support 43. The connector 42 slides up and down within the upper support 41. The locking screw 44 passes through the upper support 41 and the connector 42 and is threadedly connected to the fixing plate 45. (See attached diagram.) Figure 4 The fixing plate 45 and the connecting piece 42 are both provided with serrations 451 on the opposite side. In this utility model, the installation height of the spray pipe 3 is adjusted by the connecting piece 42 sliding up and down in the upper support 41. After the height is adjusted, the connecting piece 42 is fixed to the upper support 41 by the locking screw 44 and the fixing plate 45. The serrations 451 ensure that the connecting piece 42 and the upper support 41 are firmly fixed and difficult to move relative to each other.
