First card article and the first draw-in groove activity clamping.
The shell is provided with the second card article on the side of gobo body, offered on the gobo body with
The second draw-in groove that second card article matches, the gobo body is with sound arrester by the second card article and the activity of the second draw-in groove
Clamping.
The sound arrester is the sound arrester of right-angle prismatic column.
The gobo body interior offers diffusion chamber and sound absorption cavity, and the second abatvoix is provided with the sound absorption cavity,
The second through hole being connected with diffusion chamber is offered on gobo this body side surface between adjacent 2 sound arresters, it is described
Gobo body interior between diffusion chamber and sound absorption cavity offers third through-hole, and the diffusion chamber and sound absorption cavity pass through threeway
Hole is connected.
The lower end of the gobo body offers discharge outlet, and the discharge outlet is connected with diffusion chamber.
The beneficial effects of the utility model are：A kind of gobo of the present utility model, is provided with removable on gobo body
The sound arrester for unloading, sound arrester is installed by card article, and installation and removal are convenient；Compared with existing gobo, sound arrester
To can preferably be absorbed by the noise after gobo proprioceptive reflex, so as to play more preferable soundproof effect.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Fig. 2 be Fig. 1 in A-A to sectional view.
Specific embodiment：
Embodiment 1
A kind of gobo as shown in Figure 1-2, including gobo body 1, between being waited from top to bottom on the gobo body 1
Anomaly row is provided with fixed plate 2, and dismountable sound arrester 3 is provided with the downside of the fixed plate 2.Fixed plate 2 with every
