DETAILED DESCRIPTION OF THE EMBODIMENTS
[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0020] The present utility model provides a technical solution. Please refer to Figure 1 , a sealing plate structure for the intake and exhaust ports of a medium and high-speed diesel engine supercharger, including: an acrylic cover plate 1, a 3M rubber-coated sleeve 2, and a hook mechanism 3. The acrylic cover plate 1 is connected to the hook mechanism 3 through injection molding. The hook mechanism 3 is arranged on the top of the acrylic cover plate 1. The 3M rubber-coated sleeve 2 is sleeved outside the acrylic cover plate 1. Assembly holes 11 are evenly distributed on the top of the acrylic cover plate 1. The acrylic cover plate 1 can be fixed outside the intake and exhaust ports of the supercharger through the assembly holes 11. The hook mechanism 3 can be used to hang a volatile corrosion inhibitor rod. The 3M rubber-coated sleeve 2 is assembled inside the acrylic cover plate 1 and extends along the edge of the acrylic cover plate 1 to form a rubber-coated lip, realizing the sealing of the acrylic cover plate 1 after assembly, replacing the original rubber gasket.
[0021] Please refer to Figure 2 and Figure 3 , the hook mechanism 3 includes a sleeve 31. The sleeve 31 is assembled on the top of the acrylic cover plate 1. A hook group 32 is assembled on the top of the sleeve 31. An iron block is embedded inside the hook group 32 to increase the self-weight of the hook group 32. A closing plate 33 is connected inside the hook group 32 through a spring hinge. An L-shaped arm 34 is inserted on the left side of the hook group 32. The top of the L-shaped arm 34 is connected to a connecting rod 37 through a hinge. The other end of the connecting rod 37 is connected to a vertical arm 36 through a hinge.
[0022] The vertical arm 36 is connected to the acrylic cover plate 1. The sleeve 31 can support the hook group 32. The hook group 32 can fix the volatile corrosion inhibitor rod. The cooperation of the connecting rod 37 and the vertical arm 36 can make the closing plate 33 descend by weight when the volatile corrosion inhibitor rod is assembled inside the closing plate 33, thereby driving the L-shaped arm 34 and the sliding arm 39 to move, clamping the volatile corrosion inhibitor rod, and resisting and limiting the closing plate 33.
[0023] A return spring 35 is connected to the outside of the L-shaped arm 34. The return spring 35 is connected to the hook group 32. The return spring 35 can drive the L-shaped arm 34 to return when not in use. A cross plate 38 is slidably connected to the top of the sleeve 31. The cross plate 38 is connected to the hook group 32. The cross plate 38 can make the hook group 32 move up and down on the top of the sleeve 31.
[0024] The top of the closing plate 33 is designed with an inclined surface, and the closing plate 33 is slidably connected to the hook group 32. The closing plate 33 with the inclined surface design can only rotate towards one end of the L-shaped arm 34, preventing the closing plate 33 from being pushed by the vapor-phase rust inhibitor rod to release the limit on the vapor-phase rust inhibitor rod. A sliding arm 39 is assembled on the right side of the L-shaped arm 34, and the sliding arm 39 is a square rubber plate, which can improve the stability when fixing the vapor-phase rust inhibitor rod.
[0025] In this solution, first, the vapor-phase rust inhibitor rod is placed inside the hook group 32. At this time, the vapor-phase rust inhibitor rod is restricted inside the hook group 32 through the cooperation of the closing plate 33 and the spring hinge. The acrylic cover plate 1 is placed at the external interface of the diesel engine, with one end of the assembly hook mechanism 3 facing downwards. The acrylic cover plate 1 is fixed through the assembly hole 11 and bolts. The 3M rubber-coated sleeve 2 replaces the rubber gasket to complete the sealing between the acrylic cover plate 1 and the diesel engine.
[0026] The hook group 32 descends due to the weight of the vapor-phase rust inhibitor rod and the hook group 32 itself, and then is transmitted through the connecting rod 37 to drive the L-shaped arm 34 to move, squeezing the vapor-phase rust inhibitor rod to one end of the closing plate 33 to fix the vapor-phase rust inhibitor rod and the closing plate 33.
[0027] Through the cooperation of the acrylic cover plate 1 and the 3M rubber-coated sleeve 2, it replaces the rubber gasket in the prior art to seal the diesel engine, thereby reducing the assembly steps, meeting the good sealing requirements, reducing the cost of shipping packaging, reducing the use of consumables, improving the overall use effect, and further tightening itself through the added hook mechanism 3 in cooperation with the weight of the vapor-phase rust inhibitor rod to prevent the vapor-phase rust inhibitor rod from shaking during use and improving the stability of the overall device during use.
