Description

[Detailed Description of the Invention] The present invention relates to the installation of a spark plug guard, foot, and fuel tank for a brush cutting engine.

The spark plug guard, foot, and fuel tank retention are
In the past, all parts were designed as separate parts, or even if a single part had multiple functions, it could only perform two functions.

In addition, these parts were separate parts when an engine with the same specifications had two types of carburetor, a diaphragm type and a float type, because the mounting position of the fuel tank was different.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, reduce the number of parts, and reduce costs by using the same parts for different models.

This invention focuses on the fact that when looking at an engine from the side, the spark plug guard, fuel tank holder, and foot are lined up almost in a vertical line, and by attaching these to the engine as an integrated frame, it is possible to create an engine with the same specifications. Because the carburetor is different from the diaphragm type and the float type, it is possible to hold a fuel tank that can be mounted above or below the engine.

An embodiment of the present invention will be described below with reference to the drawings.

Figure 1 is an overall view of a general brush cutter, Figure 2 is an example of an engine equipped with a frame body according to the present invention with a diaphragm carburetor attached, Figure 3 is a side view of Figure 2, and Figure 4 is a side view of Figure 2. The figure shows an example in which the frame according to the present invention is attached to an engine equipped with a float type carburetor. The frame body 5 according to the present invention is attached to the fan cover 6 with four screws 7 to the crankcase 12 of the engine 2 to which the diaphragm carburetor 10 is attached.
It protects the spark plug 11 fixed to the cylinder 14 and holds the tank 8 via the rubber pad 13. Further, the frame body 5 forms a foot portion 9 for supporting the engine 2 at a lower portion thereof.

On the other hand, as shown in FIG. 4, the engine 2 with the diaphragm carburetor attached as shown in FIGS. 2 and 3 is turned upside down with the frame 5 fixed, and the tank 8 is It was moved above the engine 2 and replaced with a float type carburetor 15. The frame body 5
The tank 8 is held above the engine 2 via a rubber pad 13, and the foot 9 below the engine 2 protects the spark plug 11 and supports the engine 2.

According to the present invention, the spark plug guard, tank holder, and foot are integrated, so the number of parts can be reduced. In addition, the tank installation is common to both engines with diaphragm type carburetors and engines with float type carburetors, so it can be used on both types of engines. It is now possible to share parts that were not shared between engines with diaphragm carburetors and engines with float carburetors because they were shared with the connecting clutch housing and fan cover.

[Brief explanation of drawings]

Fig. 1 is an overall perspective view of a general brush cutter, Fig. 2 is a front view of an embodiment of an engine equipped with a frame body according to the present invention, in which a diaphragm type carburetor is attached, and Fig. 3 is a side view of Fig. 2. 4 are side views of an example in which the frame according to the present invention is attached to an engine equipped with a float type carburetor. In the figure, 1 is the main rod, 2 is the engine, 3 is the handle, 4 is the cutting blade, 5 is the frame, 6 is the fan cover,
7 is a screw, 8 is a tank, 9 is a foot part, 10 is a diaphragm type carburetor, 11 is a spark plug,
12 is the crank case, 13 is the rubber part, 1
4 is a cylinder, 15 is a float type carburetor,
16 is a clutch housing, 17 is a spark plug guard, and 18 is a tank holding portion.

Claims (1)

[Scope of utility model registration request] The main rod has an engine at one end and a cutting blade at the other end.
In the brush cutter having a handle in the middle, a spark plug guard portion is provided on the side of the engine to protect the spark plug, and the brush cutter as a whole is supported to prevent the brush cutter from tipping over when the brush cutter is placed on the ground. By having a frame body integrally formed with a foot part for holding a fuel tank and a tank holding part for holding a fuel tank of the engine, the frame body and the engine can be used in common for both a diaphragm type and a float type. An engine for a brush cutter.
