[0027] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.
[0028] Reference Figure 1-6 As shown, a muffler mounting bracket includes a housing 1, which is shark fin shaped. A mounting plate 2 is located at the bottom of the housing 1, and a snap-fit mechanism 3 is located at the bottom of the mounting plate 2. A mounting bracket 4 is located at the bottom of the snap-fit mechanism 3. The snap-fit mechanism 3 includes a mounting box 301. Two sets of positioning grooves 302 are formed at the top of the mounting box 301. Two sets of guide rods 303 are horizontally arranged inside the mounting box 301. Two sets of movable plates 304 are slidably mounted on the outer surfaces of the two sets of guide rods 303. A space is provided between the outer sides of the two sets of movable plates 304 and the inner wall of the mounting box 301. There is a first spring 306. The inner sides of the two sets of movable plates 304 are provided with insert rods 305 facing each other at the position corresponding to the positioning groove 302. The inside of the mounting box 301 is provided with two sets of sliding rods 307 vertically. The outer surfaces of the two sets of sliding rods 307 are slidably mounted with slide plates 309. The outer surfaces of the two sets of sliding rods 307 are provided with second springs 308. The top of the sliding rods 307 is provided with a push block 310 at the position corresponding to the positioning groove 302. The bottom end of the slide plate 309 passes through the bottom end of the mounting box 301 and is provided with a connecting rod 311. The two sets of connecting rods 311 are fixedly connected to the pressure plate 312.
[0029] In this design, when the mounting post 203 is inserted into the positioning slot 302, the insertion rod 305 automatically engages with the locking slot 204 under the action of the first spring 306, achieving quick and secure fixation and effectively preventing accidental detachment between the mounting plate 2 and the mounting bracket 4. When the mounting plate 2 needs to be disassembled, simply press the pressure plate 312. The pressure plate 312 drives the sliding plate 309 to move upward along the sliding rod 307 via the connecting rod 311, compressing the second spring 308. At the same time, the sliding plate 309 pushes the push block 310 upward, and the push block 310 pushes the insertion rod 305 outward, causing the insertion rod 305 to exit from the locking slot 204, thereby separating the mounting plate 2 from the mounting bracket 4 and improving the efficiency of maintenance and replacement of the muffler.
[0030] Reference Figure 1-3 As shown, four sets of positioning plates 101 are provided at the bottom of the inner wall of the housing 1, and an air inlet groove 102 is provided on the rear side of the housing 1. Two sets of grilles 103 are provided inside the air inlet groove 102.
[0031] In this design, the air intake slot 102 allows external air to enter the housing 1, while the grille 103 filters dust and debris, preventing them from entering the housing 1 and damaging components such as the muffler. At the same time, it ensures that the incoming air is evenly distributed, which helps dissipate heat inside the housing 1, maintains the muffler in a suitable operating temperature environment, and extends the service life of the muffler.
[0032] Reference Figure 1-2 As shown, the top of the mounting plate 2 is provided with fixing posts 201 corresponding to the positions of the four sets of positioning plates 101. All four sets of fixing posts 201 are inserted into the interior of the positioning plates 101. The bottom of the mounting plate 2 is provided with an air outlet pipe 202. The bottom of the mounting plate 2 is provided with a mounting post 203 corresponding to the position of the positioning groove 302. The mounting post 203 is inserted into the top of the mounting box 301 through the positioning groove 302. The two sets of mounting posts 203 are provided with snap-fit grooves 204 corresponding to the positions of the insertion rods 305. The insertion rods 305 are inserted into the interior of the snap-fit grooves 204.
[0033] In this solution, by setting the positioning plate 101, a precise positioning reference is provided for the installation of the mounting plate 2, ensuring that the mounting plate 2 can be accurately installed in the designated position of the housing 1, thus guaranteeing the neatness and stability of the internal structure.
[0034] The working principle of this utility model is as follows: First, the muffler is placed on the mounting plate 2. Four sets of positioning plates 101, located at the bottom of the inner wall of the housing 1, provide a precise positioning reference for the installation of the mounting plate 2, ensuring that the housing 1 can be accurately installed on the mounting plate 2, thus guaranteeing the neatness and stability of the internal structure. After the muffler is installed, the mounting post 203 is inserted into the mounting box 301. When the mounting post 203 is inserted into the positioning groove 302, the insertion rod 305 automatically engages with the snap-fit groove 204 under the elastic action of the first spring 306, allowing the mounting plate 2 to... The quick and secure fastening between the mounting plate 2 and the mounting box 301 effectively prevents accidental detachment. When the mounting plate 2 needs to be removed, simply press the pressure plate 312. The pressure plate 312 drives the sliding plate 309 to move upward along the sliding rod 307 via the connecting rod 311, compressing the second spring 308. At the same time, the sliding plate 309 pushes the push block 310 upward, and the push block 310 pushes the insertion rod 305 outward, causing the insertion rod 305 to exit from the snap-fit groove 204. This facilitates the easy separation of the mounting plate 2 from the mounting box 301, reducing operation time and difficulty.
