[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 This utility model provides a technical solution:

[0024] An intake muffler device for controlling gas emissions includes a mounting plate 1 and a muffler body 6. The mounting plate 1 has four mounting holes 2 arranged in a rectangular array. Two fixing plates 3 are fixedly connected to the bottom of the mounting plate 1. The fixing plates 3 have an L-shaped cross-section and are arranged left and right with the central axis of the mounting plate 1 as the axis of symmetry. The side wall of the fixing plates 3 has a slot 13. A pressure plate 4 is provided between the two fixing plates 3. The muffler body 6 is located at the bottom of the pressure plate 4. A support plate 5 is provided at the bottom of the muffler body 6.

[0025] Both the pressure plate 4 and the support plate 5 have arc-shaped cross-sections. The inner sides of both the pressure plate 4 and the support plate 5 are fixedly connected with buffer pads 7. The left and right sides of both the pressure plate 4 and the support plate 5 are fixedly connected with connecting plates 8. Two through holes 9 are opened on the connecting plates 8. Two grooves 10 are opened on the bottom inner side of the fixing plate 3. Screws 11 are movably inserted into the inner cavity of the grooves 10. The top of the screws 11 movably passes through the two adjacent through holes 9 and is fitted with nuts 12. The screws 11 and nuts 12 are threadedly connected. The screws 11 and grooves 10 are matched with each other.

[0026] In this embodiment: the muffler body 6 refers to the structure of the muffler body in a muffler mounting bracket for automobile exhaust emission, which is disclosed in Chinese Patent Publication No. CN216477551U.

[0027] Working Principle: This utility model discloses an intake muffler device for controlling gas emissions. When using this automotive exhaust muffler mounting bracket, the mounting hole 2 facilitates the fixing of the mounting plate 1 to the vehicle chassis. After the mounting plate 1 is fixed, the four screws 11 are moved, inserting the nut portions of the four screws 11 into the inner cavities of the four grooves 10. Then, the support plate 5 is moved, causing the connecting plates 8 on both sides to move until the through holes 9 on the connecting plates 8 on both sides of the support plate 5 correspond to the tops of the screws 11. Then, the support plate 5 is moved downwards until it is in contact with the inner bottom of the fixing plate 3. At this time, the screws 11 pass through the through holes 9 on the connecting plates 8 on both sides of the support plate 5. Make a perforation 9, then move the muffler body 6 to the inside of the support plate 5, then move the pressure plate 4 to the top of the muffler body 6. At the same time, the perforation 9 on the connecting plates 8 on both sides of the pressure plate 4 aligns with the top of the screw 11. Then move the pressure plate 4 downwards. When the pressure plate 4 moves, it fits against the top of the muffler body 6. At this time, the screw 11 passes through the perforation 9 on the connecting plates 8 on both sides of the pressure plate 4. Then put on the nut 12 and tighten the nut 12. At this time, the bottom end of the screw 11 is limited by the groove 10. When tightening the nut 12, the screw 11 will not rotate. Therefore, you only need to rotate the nut 12 to complete the installation of the muffler body 6.

[0028] When installing the muffler body 6, simply insert the screw 11 into the inner cavity of the groove 10, then install the support plate 5. The support plate 5 is supported by the fixing plate 3, so there is no need to support the support plate 5. Then move the muffler body 6, then install the pressure plate 4, and finally put on the nut 12 and tighten it. When tightening the nut 12, the bottom end of the screw 11 is limited by the groove 10, and the screw 11 will not rotate when tightening the nut 12. Therefore, only the nut 12 needs to be rotated. Thus, the above operation can be completed by one person. The operation is simple and convenient, and the workload is small.

[0029] The slot 13 provides a sufficiently large operating space for tightening the nut 12, preventing the side wall of the fixing plate 3 from obstructing the installation of the nut 12 and facilitating the installation work.
