Technical Field

[0001] The utility model belongs to the technical field of silencers, and in particular relates to an elbow-type imported plug-in silencer. Background Art

[0002] When noisy air enters a bend, the direction of the airflow is altered, causing the noise to impact the inner wall of the bend. This requires the use of a muffler to reduce noise in pipe bends. Traditional muffler designs often incorporate internal muffler panels to reduce noise. However, traditional muffler panels often suffer from a simple structure, poor noise reduction, and difficulty in installation and maintenance. These shortcomings limit the effectiveness of mufflers in various environments.

[0003] Chinese patent number CN218762100U discloses a pipe elbow muffler, which includes a muffler plate. The muffler plate is a fixed structure and is not easy to disassemble, making it inconvenient to maintain the muffler plate. Therefore, it is urgent to design an elbow-type inlet plug-in muffler to solve the above problems. Utility Model Content

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] Example 1

[0021] like Figure 1 and Figure 2As shown, the present invention provides an embodiment of an elbow-type inlet plug-in silencer, comprising a curved tube 1, wherein a plurality of silencer plates 2 are provided in the curved tube 1. The silencer plates 2 are arc-shaped plates, and the arc direction of the silencer plates 2 is consistent with the arc direction of the curved tube 1. A bracket 3 is provided at the inlet of the curved tube 1, and the bracket 3 is provided with a plurality of grooves 4. The ends of the silencer plates 2 are abutted and connected with the grooves 4, and a limiting mechanism 5 is provided at the mouth of the grooves 4. In the embodiment of the present invention, the silencer plates 2 and the bracket 3 are in a plug-in movable connection. When the silencer plates 2 are maintained and repaired, the silencer plates 2 are pulled out of the bracket 3 for maintenance and repair. The present invention effectively improves the sound-absorbing effect by providing a plurality of arc-shaped silencer plates in the curved tube that are consistent with the arc direction of the curved tube. The silencer plate is connected to the groove on the bracket by abutting and fitting, and is provided with a limiting mechanism 5, which makes the connection between the silencer plate 2 and the groove 4 more secure, thereby ensuring that the silencer will not become loose due to vibration and other reasons during long-term use, further improving the silencer effect. In the embodiment of the present utility model, the silencer plate 2 not only plays the role of guiding the airflow and reducing the impact of the airflow on the inner wall of the bend, but also plays the role of silencing and reducing noise. The utility model has a simple structure and is convenient and practical. The silencer plate 2 includes a plate body 21 and a fixing plug 22, and the plate body 21 is fixedly connected to the fixing plug 22, and the fixing plug 22 is connected to the groove 4 by abutting and fitting. In the embodiment of the utility model, the fixing plug 22 is plug-fitted and connected to the groove 4, and the upper end size of the groove 4 is larger than the lower end size, and the upper end size of the fixing plug 22 is larger than the lower end size. This makes the combination of the fixing plug 22 and the groove 4 tighter and more secure, reduces the vibration of the silencer plate 2, and reduces the noise of the silencer.

[0022] The plate body 21 is provided with sound-absorbing cotton.

[0023] The limiting mechanism 5 comprises a pin 51, a baffle 52, and a spring 53. The pin 51 is fixedly connected to the bracket 3, the baffle 52 is connected to the rotating shaft of the pin 51, and the spring 53 is sleeved on the pin 51. One end of the spring 53 is fixedly connected to the baffle 52, and the other end is fixedly connected to the bracket 3. A pull ring 23 is provided on the fixing plug 22. In this embodiment of the utility model, a stop pin is provided on the bracket 3, one on each side of the baffle 52, to limit the free rotation of the baffle 52. When the muffler 2 is installed and used, the baffle 52 is rotated a certain angle to expose the groove 4. At this time, the muffler 2 is inserted into the groove 4 and further into the curved tube 1. The baffle 52 is released, and the baffle 52 rotates under the action of the spring 53, which is a torsion spring, to drive the baffle 52 to rotate. When the baffle 52 rotates to a certain angle, it blocks the fixing plug 22 of the muffler 2, and the baffle 52 rotates to the stop pin position and stops rotating. Spring 53 allows baffle 52 to rotate to a certain extent, while the stop pin prevents the baffle 52 from rotating. The spring 53 and the stop pin cooperate to limit the rotation of baffle 52 within a certain range. In this embodiment of the utility model, the muffler 2 serves to guide airflow while reducing refraction or reflection of airflow within curves, thereby blocking sound waves. When the muffler 2 needs to be inspected and maintained, the baffle is removed from the fixing plug 22 and the muffler 2 is pulled out for maintenance using the pull ring 23.

[0024] A sink is provided in the groove 4 .

[0025] The groove 4 shown is a rectangular groove or an annular groove.

[0026] Of course, the above embodiments are not intended to limit the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
