DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0014] Example: Figure 1-3As shown, the utility model provides a decorative cover for a concealed fire sprinkler, comprising a decorative cover 1, first empty grooves 11 are provided on both sides of the decorative cover 1, limiting columns 12 are fixedly installed on both sides of the inner wall of each first empty groove 11, and the outside of each two limiting columns 12 is movably sleeved with the same spring 13, an oblique connecting rod 14 is fixedly installed at one end of the spring 13, a first connecting rod 15 is fixedly installed at one end of the oblique connecting rod 14 away from the spring 13, and a second connecting rod 16 corresponding to the first connecting rod 15 is fixedly installed at one end of the spring 13 away from the oblique connecting rod 14, a first connecting plate 17 is fixedly inserted at one side of each first connecting rod 15 and the corresponding second connecting rod 16 away from the spring 13, and a second connecting plate 18 is fixedly installed at one side of each first connecting plate 17 away from the spring 13, and a shell 2 is fixedly installed at the bottom end of the decorative cover 1, and a cover 21 is provided at the bottom end of the shell 2, and the diameter of the cover 21 is larger than the diameter of the shell 2, so as to make it easier to connect the cover 21 and the shell 2.

[0015] The outer side of the shell 2 is penetrated with four second empty grooves 22 evenly distributed in an annular shape, and the interior of the second empty grooves 22 is fixedly installed with connecting blocks 23. By setting the connecting blocks 23, it is convenient for the staff to know where to put the fusible alloy on the shell 2 and the cover 21, so as to fix the shell 2 and the cover 21 together through the fusible alloy.
