Description

Technical Field

[0001] The utility model belongs to the technical field of exhaust manifolds, and in particular relates to an easy-to-install automobile exhaust manifold assembly. Background Art

[0002] The exhaust manifold is connected to the engine cylinder block, and collects the exhaust from each cylinder and introduces it into the exhaust manifold, which has divergent pipes.

[0003] When installing the exhaust manifold, it needs to be manually placed on the side of the engine with the exhaust end so that the mounting plate on the manifold fits with the exhaust end. At this time, the mounting holes on the mounting plate need to be aligned with the mounting holes on the exhaust end, and then the bolts are inserted into the corresponding two mounting holes and tightened. However, during the assembly and installation process, due to the narrow position of the mounting holes on the mounting plate, it is difficult to align the mounting holes on the mounting plate and the exhaust end, which is not conducive to inserting the bolts into the mounting holes. In addition, since the mounting plate on the exhaust manifold is generally manually fitted to the exhaust end, the mounting plate cannot be completely fitted during fitting. When the bolts are inserted into the mounting holes, the bolts will be subjected to extrusion force, which is not conducive to the bolts being stably screwed into the mounting holes. At the same time, the bolts will be damaged during the screwing process. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] refer to Figure 1-3 As shown, the utility model provides an easy-to-install automobile exhaust manifold assembly, comprising: an engine body 4 and an exhaust manifold body 1 connected to the exhaust end 5 on the engine body 4, a mounting plate 3 is provided at the end of the exhaust manifold body 1, and a docking piece for positioning and alignment is provided on the mounting plate 3, one end of the docking piece can be inserted into the exhaust end 5, and the mounting plate 3 and the exhaust end 5 are positioned and aligned based on the insertion.

[0023] Combine Figure 1-3 and Figure 5 As shown, the docking piece is a hollow docking end 2 , and an interface 11 is provided at the end of the exhaust end 5 , and the docking end 2 is plugged into the interface 11 .

[0024] As described above, when using the engine body 4, exhaust manifold body 1, mounting plate 3 and docking piece provided by the present invention, the docking end 2 on the mounting plate 3 is inserted into the exhaust end 5 through the interface 11. At this time, the mounting plate 3 and the exhaust end 5 can be positioned so that the mounting holes on the mounting plate 3 can be aligned with the mounting holes on the exhaust end 5, making it easier for the bolts to be assembled between the mounting plate 3 and the exhaust end 5.

[0025] In this utility model, combined with Figure 2 As shown, a support rod 7 for balancing support is provided between the exhaust manifold body 1 and the engine body 4 of this embodiment, and a pipe clamp 6 fixed to the exhaust manifold body 1 is provided at one end of the support rod 7 facing away from the engine body 4, and one end of the support rod 7 abuts against the engine body 4.

[0026] Combine Figure 4 As shown, a telescopic rod 9 for length adjustment is provided between the support rod 7 and the engine body 4. One end of the telescopic rod 9 is movably inserted into the support rod 7. A limiting member for limiting the telescopic rod 9 is provided on the support rod 7. One end of the telescopic rod 9 is provided with a shock-absorbing pad 10 that abuts against the engine.

[0027] As described above, when using the support rod 7 provided by the present invention, the support rod 7 is fixedly mounted on the exhaust manifold body 1 through the pipe clamp 6. When the mounting plate 3 is mounted on the exhaust end 5, the shock-absorbing pad 10 on the telescopic rod 9 is abutted against the engine body 4. At this time, the limiter is tightened to fix the telescopic rod 9 on the support rod 7, and then the exhaust manifold body 1 is horizontally supported by the support rod 7 and the telescopic rod 9, so that the mounting plate 3 and the exhaust end 5 can fit tightly.

[0028] Further, in order to facilitate the adjustment of the length of the telescopic rod 9, refer to Figure 4 As shown, the end of the support rod 7 is provided with a telescopic hole 12 for accommodating the telescopic rod 9. A spring 13 is disposed in the telescopic hole 12 for elastically pushing out the telescopic rod 9, and one end of the spring 13 abuts against the telescopic rod 9. The telescopic rod 9 can be telescopically mounted on the support rod 7 through the telescopic hole 12, and the spring 13 always keeps the telescopic rod 9 pushed out of the telescopic hole 12. When the mounting plate 3 is mounted on the exhaust port 5, the telescopic rod 9 retracts into the telescopic hole 12, compressing the spring 13. The elastic force of the spring 13 then keeps the shock-absorbing pad 10 on the telescopic rod 9 in constant contact with the engine body 4.

[0029] Further, in order to facilitate the position limiting of the telescopic rod 9, refer to Figure 2 and Figure 4 As shown, the stopper includes an adjusting bolt 8. A threaded hole 14 is formed on the outside of the support rod 7 near one end of the telescopic rod 9, which is connected to the through hole. The adjusting bolt 8 is threaded through the threaded hole 14, and one end of the adjusting bolt 8 abuts the telescopic rod 9. By tightening the adjusting bolt 8 in the threaded hole 14, the end of the adjusting bolt 8 abuts the telescopic rod 9, thereby preventing the telescopic rod 9 from extending or retracting in the telescopic hole 12. At this point, the telescopic rod 9 can be fixed to the support rod 7.

[0030] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
