[0002] A carburetor is a mechanical device that is primarily used to mix gasoline and air to form a combustible mixture for use in the engine. It uses the vacuum created by the engine's operation and the kinetic energy of the inhaled air flow to atomize the gasoline. It automatically proportions the corresponding concentration and quantity of the mixture according to the engine's different operating requirements. The carburetor diaphragm plays an important role in the carburetor. It is primarily used to regulate the amount and speed of fuel entering the engine to achieve uniform mixing and supply of the fuel.

[0003] During the assembly of the carburetor diaphragm, ensure that each groove of the diaphragm is tightly cut and installed in the correct position. After the diaphragm is installed in place, continue to install other accessories, such as push rods, springs, balance sense, etc., and ensure that all accessories are correctly installed in place. After the installation is completed, the high-speed screw and mixture screw of the carburetor need to be adjusted to ensure that the engine idle speed and high speed meet the requirements.

The inner wall of the groove 8 is clamped with the positioning frame 10, and the positioning frame 10 is arranged in a U-shaped shape. The inner wall of the positioning frame 10 is slidably connected to a slide rod 11, and the outer wall of the positioning frame 10 is fixedly connected to a spring 12, and the end of the spring 12 is fixedly connected to a rubber block 13. The outer wall of the positioning piece 7 is provided with a socket 14, and the socket 14 facilitates the insertion of the rubber block 13 to provide positioning force to the positioning piece 7. A positioning component is provided on the surface of the carburetor body 1.

[0034] Reference Figure 4-Figure 6 The positioning assembly includes a positioning rod 5, the end of the positioning rod 5 is fixedly connected to the outer wall of the carburetor body 1, a positioning hole 4 is provided on the surface of the diaphragm 3, the outer wall of the positioning rod 5 is adapted to the inner wall of the positioning hole 4, the inner wall of the socket 14 is adapted to the outer wall of the slide rod 11, the rubber block 13 is conically arranged, and the diameter of the rubber block 13 close to the slide rod 11 is greater than the diameter of the rubber block 13 away from the slide rod 11. The end of the rubber block 13 close to the slide rod 11 is provided with an annular groove so that when it is embedded in the socket 14, the end of the rubber block 13 with a larger diameter has deformation ability. The spring 12 is sleeved on the outer wall of the slide rod 11, and the end of the spring 12 away from the rubber block 13 is fixedly connected to the outer wall of the positioning frame 10.

[0035] Reference Figure 2 、 Figure 5 The surface of the diaphragm 3 is fitted with a gasket 15, and the side wall of the gasket 15 is fitted with the side wall of the diaphragm 3.
