Description

Technical Field

[0001] The utility model belongs to the technical field of heavy truck automobile parts, and in particular relates to a fixing device for an automobile muffler tank. Background Art

[0002] With the improvement of domestic and international emission regulations, domestic medium and heavy trucks have begun to be equipped with diesel engines that meet the National IV and National V emission standards. In order to make the emissions of medium and heavy trucks meet the standards, in addition to the need to improve the engine itself, the exhaust gas also needs to be post-processed, and SCR or DPF post-processors must be used in the vehicle exhaust system. Due to the limitation of the space for the whole vehicle layout, the current SCR or DPF after-processors are mostly integrated inside the muffler, which increases the weight of the muffler by 10-20Kg. Therefore, when fixing the muffler, the muffler is generally fixed in the heavy truck by a fixing frame, and one end of the muffler is limited by a limit block to prevent the muffler from loosening due to vibration during the operation of the vehicle. However, the limit block on the surface of the muffler is generally fixedly welded on the surface of the fixing frame, so the position of the limit block is fixed, and the muffler can be changed in size according to the size of the installation space. Therefore, when fixing mufflers of different sizes by the fixing frame, the limit block is fixed and cannot adapt to mufflers of different sizes, thereby reducing the flexibility and versatility of the fixing frame. Utility Model Content

[0003] The purpose of the utility model is to provide a fixing device for an automobile muffler to solve the problems raised in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixing device for a car muffler, comprising:

[0005] A first fixing rod, a second fixing rod is fixed to one side of the first fixing rod through a connecting rod, and the first fixing rod and the second fixing rod are arranged in an L shape to form a mounting frame to fix the automobile muffler, a mounting plate is provided on one side of the first fixing rod, a plurality of fixing frames are provided on the surface of the mounting plate, fixing ears are provided on the surfaces of the first fixing rod and the second fixing rod, and a second mounting hole is provided on the surface of the fixing ears, and a limit block for limiting the automobile muffler is slidably sleeved on one end surface of the first fixing rod and the second fixing rod, and two groups of threaded holes are provided on the surface of the limit block.

[0006] Preferably, an arc-shaped piece is provided on the surface of the limit block.

[0007] Preferably, the surface of the fixing frame is provided with a first mounting hole for screwing and fixing the mounting frame.

[0008] Preferably, a crossbeam is fixedly connected to one end between the first fixing rod and the second fixing rod and away from the limiting block.

[0009] Preferably, mounting blocks are provided on the surfaces of the first fixing rod and the second fixing rod and located on the top of the cross beam.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] (1) When fixing the muffler, first, the fixing frame on the surface of the mounting plate is screwed and fixed to a predetermined position of the heavy truck by bolts passing through the first mounting holes. Then, the mounting block is screwed and fixed to the body of the heavy truck by bolts to enhance the stability of the mounting frame installation and ensure that the muffler can be stably placed between the first fixing rod and the second fixing rod. Next, the muffler is screwed and fixed to the muffler through the second mounting holes on the surfaces of the two sets of fixing ears, thereby fixing the muffler to the surfaces of the first fixing rod and the second fixing rod.

[0012] (2) When the silencer needs to be limited, the limit block on the surface of the first fixing rod and the second fixing rod can be slid so that the arc-shaped piece on the surface of the limit block contacts the arc-shaped outer surface of the silencer, thereby limiting the installed silencer to prevent the silencer from loosening. After the limit block is slid until it contacts the silencer, it can be screwed to the threaded hole on the surface of the limit block through two sets of bolts. When the bolts are continuously screwed, the bolts move into the threaded holes and contact and tighten with the first fixing rod and the second fixing rod respectively, thereby increasing the resistance to the movement of the limit block through the bolts and making the limit block unable to move. By sliding the limit block on the first fixing rod and the second fixing rod, the position of the limit block can be adjusted according to the size of the silencer, so that the limit block can limit silencers of different sizes, thereby greatly improving the flexibility and versatility of the fixing frame.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] The utility model provides Figure 1-2 A fixing device for a vehicle muffler tank is shown, comprising:

[0018] A first fixing rod 1, a second fixing rod 3 is fixed to one side of the first fixing rod 1 through a connecting rod 2, and the first fixing rod 1 and the second fixing rod 3 are arranged in an L shape to form a mounting frame to fix the automobile muffler, a mounting plate 4 is arranged on one side of the first fixing rod 1, and a plurality of fixing frames 5 are arranged on the surface of the mounting plate 4, fixing ears 7 are arranged on the surfaces of the first fixing rod 1 and the second fixing rod 3, and a second mounting hole 8 is arranged on the surface of the fixing ear 7, and a limit block 9 for limiting the automobile muffler is slidably sleeved on one end surface of the first fixing rod 1 and the second fixing rod 3, and two groups of threaded holes 10 are arranged on the surface of the limit block 9.

[0019] The surface of the limiting block 9 is provided with an arc-shaped piece 11, and the arc-shaped piece 11 can contact with the arc-shaped outer surface of the muffler, so as to limit the installed muffler.

[0020] The surface of the fixing frame 5 is provided with a first mounting hole 6 for screwing and fixing the mounting frame.

[0021] A crossbeam 12 is fixedly connected between the first fixing rod 1 and the second fixing rod 3 and at one end away from the limiting block 9 . The crossbeam 12 can enhance the firmness of the connection between the first fixing rod 1 and the second fixing rod 3 .

[0022] A mounting block 13 is provided on the surface of the first fixing rod 1 and the second fixing rod 3 and located on the top of the cross beam 12. The mounting block 13 is screwed and fixed to the body of the heavy truck by bolts to enhance the stability of the mounting frame installation.

[0023] The fixing device of the automobile muffler, when fixing the muffler, firstly, the fixing frame 5 on the surface of the mounting plate 4 is screwed and fixed to the predetermined position of the heavy truck by bolts penetrating the first mounting holes 6, and then, the mounting block 13 is screwed and fixed to the body of the heavy truck by bolts, so as to enhance the stability of the installation of the mounting frame and ensure that the muffler can be stably placed between the first fixing rod 1 and the second fixing rod 3, and then, the second mounting holes 8 on the surfaces of the two groups of fixing ears 7 are screwed and fixed to the muffler, so as to fix the muffler to the surfaces of the first fixing rod 1 and the second fixing rod 3.
