Embodiment Construction

[0016] The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0017] Embodiment 1 of the present invention is, as figure 1 As shown, the first shell 10 and the second shell 20 are included, the first shell 10 and the second shell 20 are both semi-circular cylinders, and the inner walls of the first shell 10 and the second shell 20 extend inwardly along the circle There are at least two partition plates 30 arranged in the axial direction of the barrel. The partition plates 30 are annular plates. The inner wall of the partition plate 30 is closely matched with the outer wall of the muffler 50. 30 divides the space between the first housing 10, the second housing 20 and the muffler into at least one muffler cavity 40, the muffler cavity 40 is provided with a muffler material, and the partition plate 30 is also provided with a ring-shaped S...

Abstract

The invention discloses an antifouling silencer strengthening device which comprises a first casing and a second casing which are both semicircular cylinders, the first casing and the second casing are matched to form a cylinder structure, and the inner walls of the first casing and the second casing extend inwards to form at least two partition plates distributed in the axial direction of the cylinder. During installation, the space among the first casing, the second casing and the silencer is divided into at least one silencing cavity through the partition plates, a silencing material is arranged in the silencing cavity, an annular sealing groove is further formed in the partition plate, and a rubber block is arranged in the sealing groove. The strengthening device effectively and conveniently solves the problem that a silencer is poor in noise reduction effect in the use process. The rubber block is arranged in the sealing groove to ensure that a sound insulation material in the whole sound insulation cavity is waterproof and antifouling, and the service life of the device is prolonged by means of the partition cavity.

Description

technical field [0001] The invention relates to an antifouling muffler strengthening device. Background technique [0002] For automobile mufflers, the noise reduction effect is the key indicator of mufflers, but for consumers or for mufflers that have been designed and finalized, it is very difficult to change the muffler structure from the inside. It is difficult to meet the needs of improving the noise reduction effect of the silencer on the basis of the original silencer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-pollution type muffler strengthening device, which can improve the noise reduction effect of the muffler on the basis of the original muffler without changing the internal structure of the muffler , especially provides an effective and convenient solution to the problem of poor noise reduction effect during the use of the muffler. At the same time, the good multi-chamber sealing design...
