Description

Technical Field

[0001] The utility model relates to the technical field of engine exhaust heat insulation covers, in particular to an engine exhaust heat insulation cover. Background Art

[0002] The exhaust pipe is a part of the engine's exhaust system. The exhaust system mainly includes the exhaust manifold, exhaust pipe and muffler. Generally, a three-way catalytic converter for controlling engine pollutant emissions is also installed in the exhaust system. The exhaust pipe generally includes a front exhaust pipe and a rear exhaust pipe. In order to avoid high-temperature melting or damage to the surrounding plastic parts and to prevent burns, a heat shield needs to be installed at the tail of the pipe.

[0003] After searching, a Chinese patent with publication number CN213063729U discloses an engine exhaust pipe heat shield, which can achieve good support and fixation effects on the exhaust pipe, preventing the exhaust pipe from breaking during vibration. At the same time, the connection sealing and stability between the device and the connecting pipe are improved to avoid heat leakage. However, this device cannot quickly install the heat shield. At present, when installing the heat shield, it takes a lot of time to fix it. Moreover, the heat shield is installed on the exhaust pipe. During installation, workers need to be located at the bottom of the car, which makes installation difficult. The heat shield that cannot be quickly installed will increase the time and energy of workers for installation, resulting in an increase in processing costs.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model sets a cover plate, a first slot, a slide groove, a U-shaped plate, a second slot, a first plug rod, a plug-in and other components, overlaps the two cover plates, and uses the U-shaped plate to slide along the slide grooves on the two cover plates. At this time, the two cover plates can be fixed together by the U-shaped plate. At this time, the two first slots will form a closed groove, and then the plug-in will be inserted along the closed groove. The plug-in will slide along the corresponding U-shaped plate until the first plug rod and the corresponding second slot are on the same central axis, and then the first plug rod is inserted into the corresponding second slot to complete the fixation of the plug-in, thereby achieving the effect that the device can quickly install the cover plate through the mutual cooperation of the plug-in and the U-shaped plate.

[0015] 2. The utility model provides components such as a clamping plate, a connecting rod, a cover plate, and a third spring. During the process of quickly installing the cover plate, the clamping plate will first come into contact and squeeze with the exhaust pipe, and then the third spring will slowly compress and cause the clamping plate to be subjected to force to clamp exhaust pipes of different sizes. The heat on the surface of the exhaust pipe is transferred through the clamping plate, thereby achieving the effect that the device can clamp exhaust pipes of different sizes through the elastic force of the third spring acting on the clamping plate.

[0024] In this embodiment, a second slot 6 is provided on the outer surface of each U-shaped plate 4, and two plug-ins 7 are slidably connected to the outer surface of each U-shaped plate 4. The plug-in 7 is a U-shaped part, which can be inserted along the overlapped first slot 5. At this time, the plug-in 7 can limit the U-shaped plate 4 and the cover plate 2, allowing the U-shaped plate 4 to slide. The outer surface of each plug-in 7 is plugged into the corresponding first slot 5, and the inner wall of each plug-in 7 is slidably connected with a first plug rod 8, and the outer surface of each first plug rod 8 is plugged into the corresponding second slot 6. Specifically, the plug-in 7 is inserted along the corresponding first slot 5. At this time, the first plug rod 8 on the plug-in 7 will slide horizontally along the U-shaped plate 4 until the first plug rod 8 and the corresponding second slot 6 are on the same central axis. At this time, the U-shaped plate 4 and the cover plate 2 can be fixed by plugging the first plug rod 8 into the corresponding second slot 6 to prevent the U-shaped plate 4 from falling off.

Specifically, when the second plug rod 14 slides along the corresponding bevel groove 11, the second plug rod 14 will move vertically along the corresponding fixing ring 13 in the opposite direction of the cover plate 2 until the second plug rod 14 moves to the same central axis as the corresponding third slot 12. At this time, the second plug rod 14 will enter the corresponding third slot 12 to complete the fixation of the fixing ring 13.
