[0002] Turbochargers are widely used in automotive engines and are gradually expanding into other applications such as ships and aircraft. They enable engines to produce greater horsepower at lower speeds, effectively improving the power and acceleration of vehicles and ships. Turbochargers also improve fuel economy, reducing engine fuel consumption and increasing engine output, thereby increasing the speed and load capacity of vehicles and ships.

[0003] The sealing device of the turbocharger in the prior art is connected to the turbocharger by bolts. However, since the turbocharger generates a large amount of heat when running at high speed, the sealing cover connected to the turbocharger by bolts will also generate or accumulate heat. When the sealing cover needs to be cooled when disassembling, the screw holes of the sealing cover will expand and contract due to heat and cold, making it difficult to disassemble the bolts.

DETAILED DESCRIPTION

[0028] The technical solution of the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0029] This embodiment provides a sealing device for a turbocharger, comprising a main body 1 and a main body 2. Figure 1As shown, the left side of the main body 1 corresponds to the main body 2, and the inner sides of the main body 1 and the main body 2 are both provided with a limit ring 3, and the inside of the limit ring 3 is inlaid with a sealing ring 4; the lower part between the main body 1 and the main body 2 is connected with a sealing cover 1 9, and the top of the sealing cover 1 9 is connected with a sealing cover 2 901; the surface of the sealing cover 1 9 is welded with a fixing plate 2 913, and the top of the fixing plate 2 913 is provided with a slot 914; the surface of the sealing cover 2 901 is welded with a fixing plate 1 908, and the inside of the fixing plate 1 908 is penetrated by an inserting plate 909; a group of sliding rods 910 are fixed to the inside of the inserting plate 909, and the outside of the group of sliding rods 910 is penetrated by a spring 2 911; the top of the sealing cover 1 9 and both sides of the bottom of the sealing cover 2 901 are inlaid with a sealing strip 1 904.

[0030] Furthermore, if Figure 2 、 Figure 5 As shown, the rear surface of the sealing cover 1 9 is fixedly connected to a group of hinges 1 902, the top of the group of hinges 1 902 is rotatably connected to hinge 2 903, hinge 2 903 is welded to the rear surface of the sealing cover 2 901, and the interior of the group of hinges 1 902 is penetrated by fixing pins. This structure facilitates the separation of the bottom of the sealing cover 2 901 from the top of the sealing cover 1 9, and at the same time prevents the sealing cover 1 9 from separating from the sealing cover 2 901 through the fixing pins.

[0031] like Figure 3 as well as Figure 4 As shown, further, a group of grooves are provided inside the sealing cover 1 9 and the sealing cover 2 901, and the inside of the grooves are adapted to the outside of the limiting ring 3 to connect the main body 1 and the main body 2 2, and then sealed by the sealing ring 4 embedded in the limiting ring 3 to prevent air leakage in the main body 1 and the main body 2 2; the internal rotation of the main body 1 is connected to the fan shaft 1 5, and the internal rotation of the main body 2 is connected to the fan shaft 2 6, and the end of the fan shaft 2 6 is provided with a limiting rod 7, which facilitates power transmission; the end of the fan shaft 1 5 is provided with a limiting groove matching the outside of the limiting rod 7, and the top of the limiting groove is connected to the fixing shell 8 by bolts, which facilitates the disassembly and separation of the main body 1 and the main body 2 2.

[0032] like Figure 7-10 As shown, further, one end of the second spring 911 abuts against the interior of the first fixed plate 908, and the other end abuts against the inserting plate 909, and the inserting plate 909 can be pushed to move by the second spring 911; Figure 9 As shown, a set of blocks 912 are welded inside the fixing plate 908, and a set of blocks 912 are respectively placed on the upper and lower sides of the slide bar 910. The right side of the plug-in plate 909 fits with the left side of the block 912, and this structure can play a limiting role; the plug-in plate 909 is slidably connected to the inside of the slot 914 to facilitate the connection of the sealing cover 9 and the sealing cover 901; Figure 10As shown, a placement groove is provided on the left side of the slot 914, and the placement groove is larger than the bottom of the plug-in board 909. This structure can prevent the bottom of the plug-in board 909 from being stuck inside the slot 914 when the sealing cover 901 is opened; the top of the plug-in board 909 extends to the top of the fixed plate 908, and the surface of the fixed plate 908 is fixedly connected to the sealing plate. This structural setting makes it easy to push the plug-in board 909 to slide inside the slot 914.

[0033] like Figure 8 、 Figure 11 as well as Figure 12 As shown, the interior of the sealing strip 1 904 is provided with two groups of sliding grooves, and the interior of the sealing strip 1 904 is provided with a sealing strip 2 905. A group of sliders 907 are provided on both sides of the sealing strip 2 905. The exterior of the sliders 907 is slidably connected to the interior of the sliding grooves, which facilitates the sealing strip 2 905 to slide up and down inside the sealing strip 1 904; the bottom of the sealing strip 2 905 is provided with multiple sockets 1, and the interiors of the multiple sockets 1 are connected to springs 1 906, which are placed inside the sealing strip 1 904, and the interior of the sealing strip 1 904 is provided with multiple sockets 2, and the interior of the sockets 2 is adapted to the bottom of the spring 1 906 to prevent the spring 2 911 from being displaced inside the sealing strip 1 904. The sealing strip 2 905 can be pushed to move inside the sealing strip 1 904 by the spring 2 911.

[0034] like Figures 1-12 As shown, the principle of the sealing device of the turbocharger provided in this embodiment is as follows: when it is necessary to perform a quick inspection or cleaning operation on the main body 1 and the main body 2, the inserting plate 909 is pushed to one side to slide inside the slot 914. When the bottom of the inserting plate 909 contacts the groove opened on the left side of the slot 914, the bottom of the sealing cover 2 901 is separated from the top of the sealing cover 1 9 by rotating the hinge 1 902 and the hinge 2 903. Then the fixed shell 8 is disassembled to complete the separation of the main body 1 and the main body 2, so as to facilitate the quick maintenance, inspection, cleaning and other operations on the main body 1 and the main body 2. When the operation is completed, the main body 1 and the main body 2 are installed relative to the sealing cover 1 9, and the sealing cover 1 is fixed. The bottom of the cover 2 901 is docked with the top of the sealing cover 1 9. Since the top of the sealing cover 1 9 and both sides of the bottom of the sealing cover 2 901 are inlaid with a sealing strip 1 904, the interior of the sealing strip 1 904 is connected to the slider 907 provided with the sealing strip 2 905 through a slide groove. The sealing strip 1 904 can push the sealing strip 1 904 to move through the spring 1 906 placed inside. Therefore, the sealing strip 2 905 on the top of the sealing cover 1 9 will be docked with the sealing strip 2 905 connected to the bottom of the sealing cover 2 901, thereby completing the seal, and pushing the plug plate 909 again so that the bottom of the plug plate 909 contacts the groove opened by the slot 914, and then the spring 2 911 passing through the outside of the slide rod 910 pushes the plug plate 909 to be inserted into the slot 914.
