DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] In order to make the purpose, technical solutions and advantages of the present application clearer, the embodiments of the present application will be further described in detail below with reference to the drawings.

[0025] Please refer to Figures 1-4 The present application is a ventilation muffler, which comprises:

[0026] The ventilation muffler body 11;

[0027] The ventilation muffler body 11 can meet the sound attenuation of the wind sound in the ventilation pipeline of the shopping mall.

[0028] The auxiliary mounting mechanism comprises a support plate 31, which is arranged above one side of the ventilation muffler body 11, and a recess is formed in the middle of the bottom end of the support plate 31. A guide block 32 is slidably connected to the end of the recess inside, and a positioning plate 34 is arranged at the middle of the lower end of the guide block 32. An active spring 33 is fixedly connected to the end of one set of guide blocks 32 and the end of one set of positioning plates 34, and the inner side of one set of positioning plates 34 is in contact with the outer surface of the ventilation pipeline.

[0029] The support plate 31 cooperates with the recess to slidably receive one set of guide blocks 32, and the positioning plate 34 is installed through the guide block 32. The contact between the inner side of the set of positioning plates 34 and the ventilation pipeline can ensure the preliminary stability of the structure of the ventilation muffler body 11, which is beneficial to the subsequent secondary installation. The active spring 33 can adjust the spacing between the set of guide blocks 32 by means of its own elastic force, and can exert a reverse force on the positioning plate 34 through the recovery deformation force to ensure the stable connection between the positioning plate 34 and the pipeline.

[0030] The middle part of the upper end of the positioning plate 34 is provided with a protruding column, which is sleeved and extends into the opening formed in the middle of the bottom end of the guide block 32.

[0031] The convex column and the opening are sleeved, and the positioning plate 34 and the guide block 32 are fixed.

[0032] The auxiliary mounting mechanism further comprises a sleeve column one 35, a sleeve column two 36 and a movable rope 37. The sleeve column one 35 is sleeved and fixed at the middle part of the upper end of the ventilation muffler body 11. The sleeve column two 36 is sleeved and fixed at the middle part of the upper end of the support plate 31. The upper middle parts of the sleeve column one 35 and the sleeve column two 36 are respectively connected with the end parts of the movable rope 37.

[0033] The sleeve column one 35, the sleeve column two 36 and the movable rope 37 are connected with the end parts of the movable rope 37, so that the auxiliary mounting mechanism is mounted on the ventilation muffler body 11. The sleeved connection mode is beneficial to the disassembly and assembly of the structure.

[0034] A rectangular protrusion is arranged at the central position in the groove. Rubber pads are arranged on the two sides of the rectangular protrusion and are in contact with the other ends of the guide blocks 32.

[0035] The rectangular protrusion protects the guide blocks 32 in sliding through the rubber pads.

[0036] Working principle: when the ventilation muffler body 11 is installed, the end parts of the movable rope 37 are connected through the sleeve column one 35 and the sleeve column two 36, so that the auxiliary mounting mechanism is mounted on the ventilation muffler body 11. At this time, an external pushing force is applied to the positioning plate 34. The spacing between the positioning plates 34 is gradually increased through the compression of the movable spring 33. The positioning plates 34 are arranged outside the ventilation pipeline of the shopping mall. After the force is released, the movable spring 33 restores the deformation and applies a reverse force to the positioning plate 34. The ventilation pipeline is used as the outer surface. The resistance between the two ensures the preliminary stability of the ventilation muffler body 11. Then, the ventilation muffler body 11 and the ventilation pipeline are fixed through the following butt joint mechanism.

[0037] The scheme helps to improve the disassembly and assembly efficiency, is convenient to use, meets the needs, and improves the use effect.

[0038] Please refer to Figures 1-4 The embodiment further comprises:

[0039] The butt joint mechanism comprises a butt joint groove 23. The butt joint groove 23 is equidistantly arranged at the upper and lower ends of the inner wall of the ventilation muffler body 11.

The upper and lower ends of the inner wall of the limiting groove 25 are in contact with the upper and lower ends of the sound insulation glass wool.

[0040] The docking groove 23 is mounted to the positioning frame 24, and cooperates with the limiting groove 25 to meet the installation of the sound insulation glass cotton structure, and through the damping sliding of the positioning frame 24 in the positioning groove, the stable structure can be ensured while the position can be moved, the sound insulation glass cotton can be conveniently removed, the shell of the main body 11 of the ventilation silencer does not need to be disassembled, time and labor are saved, and use is facilitated.

[0041] The docking mechanism further comprises a docking frame one 21, the docking frame one 21 is symmetrically fixed at the end of the main body 11 of the ventilation silencer, and the outer side of the docking frame one 21 is fixed with a docking frame two 22;

[0042] Threaded pipes 26 are arranged through the edges and corners of the docking frame two 22, threaded rings 27 are arranged on the outer surface ends of the threaded pipes 26 in a threaded mode, and extend into the docking frame two 22;

[0043] The docking frame one 21 supports the docking frame two 22, the threaded pipes 26 are fixed through the threaded rings 27, and the main body 11 of the ventilation silencer and the ventilation pipeline can be fixed and installed through the bolts placed in the threaded pipes 26 and tightened.

[0044] Working principle: after the above-mentioned auxiliary installation mechanism ensures the preliminary stability between the main body 11 of the ventilation silencer and the ventilation pipeline, the bolts are placed in the threaded pipes 26 and tightened, the main body 11 of the ventilation silencer and the ventilation pipeline are docked and fixed, and the reverse operation can be performed when disassembling, and the shell of the main body 11 of the ventilation silencer does not need to be disassembled when the sound insulation glass cotton is replaced, and the multiple positioning frames 24 can be removed in sequence.
