Description

Technical Field

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 2 , the utility model provides an embodiment: a chain saw magnetic flywheel with heat dissipation function, comprising a chain saw magnetic flywheel body 1, a flywheel blade 1 2 is fixedly connected to the upper surface of the chain saw magnetic flywheel body 1, a connecting shaft 3 is fixedly connected inside the chain saw magnetic flywheel body 1, a flywheel blade 2 4 is fixedly connected to the lower surface of the chain saw magnetic flywheel body 1, a heat dissipation groove 5 is opened inside the flywheel blade 2 4, an inclined blade 6 is fixedly connected inside the flywheel blade 2 4, there are seven inclined blades 6 on the flywheel blade 2 4, there are twelve flywheel blades 1 2 and twelve flywheel blades 2 4 respectively, and an auxiliary component is arranged on the upper surface of the chain saw magnetic flywheel body 1;

[0024] Specifically, the rotation of the oil saw magnetic flywheel body 1 will drive the flywheel blade 1 2 and the flywheel blade 2 4 which are closely connected thereto to rotate together, which undoubtedly increases the surface area of ​​the oil saw magnetic flywheel body 1, so that more heat can be effectively conducted to the surrounding air, thereby accelerating the heat dissipation process. In this process, the heat dissipation groove 5 transfers the heat from the oil saw magnetic flywheel body 1 to the surrounding environment by heat conduction, which can effectively reduce the temperature of the oil saw magnetic flywheel body 1 and ensure its normal operation. In addition, the setting of the inclined blades 6 is even more ingenious. It increases the surface area of ​​the flywheel and further improves the heat dissipation efficiency, so that the heat generated by the oil saw magnetic flywheel body 1 can be more effectively dissipated to the surrounding environment, which can not only avoid aging and wear of components caused by overheating, but also undoubtedly provides a strong guarantee for the stable operation of the engine.

[0025] Reference Figure 1 , Figure 3 and Figure 4The auxiliary component includes a button block 7, a connecting column 8 is fixedly connected to the lower surface of the button block 7, a support plate 9 is fixedly connected to the outer wall of the connecting column 8, a rotating rod 10 is rotatably connected to the upper surface of the support plate 9, a sliding block 11 is rotatably connected to the lower surface of the rotating rod 10, a supporting block 13 is arranged at the bottom of the sliding block 11, a sliding rail 12 is fixedly connected to the upper surface of the supporting block 13, the connecting column 8 is rotatably connected to the inside of the supporting block 13, the sliding block 11 is slidably connected to the side wall of the sliding rail 12, and a cavity 17 is opened inside the magnetic flywheel body 1 of the chainsaw;

[0026] Specifically, during the installation of the chain saw magnetic flywheel body 1, the operator needs to strictly follow the steps to ensure the stability and safety of the installation. First, the operator will fasten the hollow column 18 to the crankshaft connected to the engine. The importance of this step is self-evident because it provides a solid foundation for the subsequent installation steps. If the installation of the hollow column 18 is unstable, the subsequent installation process may be affected, thereby affecting the normal operation of the entire chain saw magnetic flywheel body 1. Next, the operator will slowly place the chain saw magnetic flywheel body 1 to the predetermined installation position. During this process, the connecting shaft 3 will first be connected to the support column 14. The establishment of this contact point is a key step in the entire installation process, which helps to accurately position the chainsaw magnetic flywheel body 1 and ensure that it can be correctly installed on the crankshaft. Subsequently, the operator rotates the button block 7 to transmit the rotation of the button block 7 to the connecting column 8, and then the connecting column 8 transmits it to the support plate 9. This chain reaction allows the rotating rod 10 to rotate smoothly on the surface of the support plate 9 and the sliding block 11. The rotation of the rotating rod 10 further drives the sliding block 11 to slide outward on the side wall of the slide rail 12. The installation and operation of each component have been carefully designed to ensure that the chainsaw magnetic flywheel body 1 can work efficiently and stably.

[0027] Reference Figure 1 , Figure 3 and Figure 4 The upper surface of the sliding block 11 is fixedly connected with a support column 14, one end of the support column 14 is fixedly connected with a fixed column 15, the outer wall of the fixed column 15 is fixedly connected with a sliding column 16, the sliding column 16 is slidably connected to the cavity 17 and the inner wall of the connecting shaft 3, and the lower surface of the support block 13 is fixedly connected with a hollow column 18;

[0028] Specifically, during the sliding process of the sliding block 11, it triggers the movement of a series of components. First, the support column 14 will start to move with the movement of the sliding block 11. The movement of the support column 14 is not carried out alone, and it also drives the corresponding movement of other components. Next, the fixed column 15 and the sliding column 16 also start to operate with the movement of the support column 14. In this process, the movement of the fixed column 15 plays a key role. It further drives the sliding column 16 to slide inside the connecting shaft 3 and the cavity 17. This step is to ensure that the oil saw magnetic flywheel body 1 can be correctly installed on the crankshaft. When the sliding column 16 reaches the appropriate position, that is, the position of engaging the oil saw magnetic flywheel body 1, the oil saw magnetic flywheel body 1 is accurately installed on the crankshaft. At this time, the oil saw magnetic flywheel body 1 has been firmly fixed in the correct position, laying the foundation for subsequent work. In the whole process, the movement of each component is interrelated and carried out in order, and each step is for the smooth progress of the next step.

[0029] Working principle: when it is necessary to install the chainsaw magnetic flywheel body 1 on the crankshaft connected to the engine, first, the operator will fasten the hollow column 18 to the crankshaft, and then the operator will slowly place the chainsaw magnetic flywheel body 1 to the installation position. At this time, the connecting shaft 3 will first contact the outer wall of the support column 14, and then, by rotating the button block 7, the rotation of the button block 7 is transmitted to the connecting column 8, and then transmitted to the support plate 9 by the connecting column 8. Such a chain reaction eventually causes the rotating rod 10 to rotate on the surface of the support plate 9 and the sliding block 11. The rotation of the rotating rod 10 further drives the sliding block 11 to slide outward on the side wall of the slide rail 12. The sliding of the sliding block 11 causes the support column 14 to start moving. With the movement of the support column 14, the fixed column 15 and the sliding column 16 will also start to move accordingly. The movement of the fixed column 15 further drives the sliding column 16 to slide inside the connecting shaft 3 and the cavity 17. When the sliding column 16 is stuck in the position of the chainsaw magnetic flywheel body 1, the chainsaw The magnetic flywheel body 1 is correctly installed on the crankshaft. At this time, the oil saw magnetic flywheel body 1 has been fixed in the correct position and can be driven to rotate by the crankshaft. After installation, the oil saw magnetic flywheel body 1 will start to work with the rotation of the engine crankshaft. The rotation of the oil saw magnetic flywheel body 1 will drive the flywheel blade 1 2 and the flywheel blade 2 4 connected thereto to rotate together, which increases the surface area of ​​the oil saw magnetic flywheel body 1, helps to conduct more heat to the surrounding air, and accelerates the heat dissipation process. At the same time, the heat dissipation groove 5 transfers the heat from the oil saw magnetic flywheel body 1 to the surrounding environment by heat conduction, effectively reducing the temperature of the oil saw magnetic flywheel body 1. The inclined blades 6 increase the surface area of ​​the flywheel and improve the heat dissipation surface, so as to more effectively dissipate the heat generated by the oil saw magnetic flywheel body 1 to the surrounding environment. Through the cooperation between the flywheel blade 1 2, the flywheel blade 2 4, the heat dissipation groove 5 and the inclined blades 6, aging and wear of components caused by overheating can be avoided.
