Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fuel injectors, in particular to a high-strength anti-deformation fuel injector pressing plate. Background Art
[0002] The injector pressure plate is an important component in the engine. It can be fixed to the engine cylinder head by bolts to limit the position of the injector in the engine and prevent the injector from shaking when the engine is running, which would affect the normal operation of the injector.
[0003] The injector pressure plate is usually used in conjunction with a sealing gasket or sealing ring to compress the injector while ensuring the seal between the injector and the mounting seat. The injector is installed vertically inside the pressure plate. When the vibration generated by the engine running acts on the injector and the injector pressure plate for a long time, the injector will produce radial displacement inside the injector pressure plate. The vibration will also slightly change the installation angle of the pressure plate and the injector, resulting in inaccurate fuel injection. Utility Model Content

[0022] In view of the problems in the prior art, the utility model provides a high-strength anti-deformation fuel injector pressing plate, including pressing plate body 11, the bottom of pressing plate body 11 is fixedly installed with installation sleeve 12, the top of pressing plate body 11 is fixedly installed with two fixed blocks 14, the side end of each fixed block 14 is slidably installed with first pressing plate 13, the inside of each first pressing plate 13 is fixedly installed with rubber pad 16, the top of each pressing plate body 11 is slidably installed with two second pressing plates 15, the inside of fixed block 14 is provided with guide groove, pressing plate body 11 and installation sleeve 12 are integrally designed, pressing plate body 11 is of aluminium alloy material, let pull rod 19 slide at the top of pressing plate body 11, the movement of first pressing plate 13 drives guide rod 22 to slide in the inside of fixed block 14, guide rod 22 guides the movement of first pressing plate 13, simultaneously, first pressing plate 13 drives buffer rod 21 to stretch at the side end of fixed block 14, by pushing two first pressing plates 13 respectively, and the interval of the movement of two first pressing plates 13 is the same, first pressing plate 13 plays the role of extruding and supporting the fuel injector, and the angle of the fuel injector and the pressing plate is corrected.
[0023] The side end of each first pressure plate 13 is fixedly installed with a base 18, and a pull rod 19 is rotatably installed inside each base 18. The top of the pull rod 19 is rotatably connected to the side end of the second pressure plate 15. Two guide rods 22 are fixedly installed on the side end of each base 18, and two buffer rods 21 are fixedly installed on the side end of each base 18. Two sealing rings 23 are fixedly installed inside the pressure plate body 11, and two reinforcement rings 24 are fixedly installed inside the mounting sleeve 12. The bottom end of each second pressure plate 15 is fixedly installed with a connecting plate 17. The top of the pressure plate body 11 is provided with two arc-shaped grooves, which are connected to the connecting plate 17. Two reinforcement rings 24 are installed inside the mounting sleeve 12. The reinforcement ring 24 is made of metal. When the injector is installed through the pressure plate body 11, the end of the injector is assembled with the engine. The end of the injector is supported and protected by the mounting sleeve 12 and the reinforcement ring 24, thereby increasing the strength of the pressure plate body 11 and the mounting sleeve 12.
[0024] Working principle:
[0025] The first step is that the pressure plate body 11 and the mounting sleeve 12 are integrally connected. Two sealing rings 23 are installed inside the pressure plate body 11. The injector is inserted into the pressure plate body 11. The outside of the injector fits with the sealing ring 23. The sealing ring 23 buffers and seals the injector. At the same time, the injector continues to pass downward through the mounting sleeve 12. The injector is fixed inside the mounting sleeve 12. Two reinforcement rings 24 are installed inside the mounting sleeve 12. The reinforcement ring 24 is made of metal. While the injector is installed through the pressure plate body 11, the end of the injector is assembled with the engine. The end of the injector is supported and protected by the mounting sleeve 12 and the reinforcement ring 24, thereby increasing the strength of the pressure plate body 11 and the mounting sleeve 12.
[0026] In the second step, threaded holes are pre-opened on both sides of the pressure plate body 11. By rotating the bolts, the pressure plate body 11 is fixed to the mounting sleeve 12, and the injector is fixed to the engine. At the same time, the bolts are rotated, and the bolts rotate inside the pressure plate body 11, applying pressure to the top ends of the two second pressure plates 15, so that the second pressure plates 15 drive the connecting plate 17 to slide on the top ends of the pressure plate body 11. The squeezed second pressure plate 15 is pressed downward to fit the top ends of the pressure plate body 11. At the same time, the second pressure plate 15 moves downward a short distance, pushing the top ends of the pull rods 19, and the top ends of the pull rods 19 rotate at the side ends of the second pressure plates 15. The deflection of the pull rod 19 applies a thrust to the first pressure plate 13, allowing the pull rod 19 to slide on the top of the pressure plate body 11. The movement of the first pressure plate 13 drives the guide rod 22 to slide on the inner side of the fixed block 14. The guide rod 22 guides the movement of the first pressure plate 13. At the same time, the first pressure plate 13 drives the buffer rod 21 to stretch at the side end of the fixed block 14. By pushing the two first pressure plates 13 separately, and the distance between the two first pressure plates 13 is the same, the first pressure plate 13 plays a role of squeezing and supporting the injector, correcting the angle between the injector and the pressure plate, and preventing the installation angle of the injector from deviating.
[0027] Finally, it should be noted that the above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
