Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for holding an accelerator cable for transmitting an accelerator operation to a throttle valve in a carburetor.

[0002]

2. Description of the Related Art An accelerator cable for transmitting a driver's accelerator operation to an engine output control throttle valve needs to be arranged in a predetermined path in order to properly correspond the throttle valve opening operation to the accelerator operation. .

Therefore, for example, in a rotary throttle valve type carburetor, it is considered that a valve body in which a cylindrical throttle valve is fitted is closed and a cover body attached to the carburetor body holds the accelerator cable. .

FIGS. 7A, 7B and 7C are views showing a conventional mechanism for holding an accelerator cable in a cover body of a rotary throttle valve type carburetor, in which a cylindrical throttle valve is fitted. The cover 72 made of synthetic resin for closing the valve hole formed is the carburetor main body 7
1 is screwed to the cover body 72, and the throttle valve lever 7 is attached to the protruding end of the throttle valve shaft 73 that penetrates the cover body 72.
4 is fixed. The inner cable 76 of the accelerator cable 75 is connected to the post of the throttle valve lever 74 through a holding metal fitting 78 fitted to the tip of the outer tube 77. The holding metal fitting 78 has a male screw 79 and is screwed with nuts 80a and 80b.

7 (A) and 7 (B), a bracket 81 is integrally formed on the cover body 72 so as to be upright, and in this bracket 81, a notch-shaped mounting groove 82 is provided in FIG. The accelerator cable 75 is held by fitting, and in (B), the mounting hole 83 is provided, the holding metal fitting 78 is inserted, and the nuts 80a and 80b are tightened from both sides of the bracket 81.
In FIG. 7C, a bracket 85 made of a steel plate is overlaid and fixed on the cover body 72, a mounting hole 86 is provided in an upright portion of the bracket 85, and a holding metal fitting 78 is inserted therethrough. The accelerator cable 75 is held by tightening 80b.

Incidentally, what is substantially the same as that shown in FIG. 7B is presented in Japanese Patent Application Laid-Open No. 11-141401, and what is shown in FIG. It is described as a technology.

[0007]

The problem to be solved by the invention is shown in FIG.
In both of the cases shown in (B) and (C), the outer tube 77 is simply fitted into the holding metal fitting 78, so that when used in a brush cutter, the accelerator cable 75 is held by being caught on a tree branch, for example. There is a concern that the engine rotation may be abnormally increased when a force in the direction of coming out of the metal fitting 78 is received. Further, those shown in (A) and (B) are cover bodies 72 made of synthetic resin due to engine heat or the like.
May soften, the nuts 80a and 80b with the bracket 81 sandwiched may loosen to cause rattling and unstable engine rotation. Particularly, in the case shown in FIG. There is a possibility that the holding metal fitting 78 may come out of the 82. Further, the one shown in (C) is the bracket 8
Since 5 is made of steel plate, there is no concern about loosening due to heat, but it is disadvantageous in terms of price. Therefore, if a thin plate is used, bending due to insufficient strength will occur and throttle valve opening operation can be appropriately responded to accelerator operation. I am worried that it will disappear.

On the other hand, looking at the assembling work for holding the accelerator cable 75 in the carburetor, the one shown in (A) fits the holding metal fitting 78 into the mounting groove 82 while the two nuts 80a and 80b are screwed, Next, nuts 80a, 8
Assembly can be performed by tightening 0b. However, in the case shown in (B) and (C), the nut 80a on the tip end side is removed from the holding metal fitting 78 and pulled out from the tip of the inner cable 76, and the inner cable 76 and the holding metal fitting 78 are inserted into the mounting holes 83, 86. Then, the nut 80a is screwed again, and the nuts 80a and 80b are tightened, so that the assembly is carried out, which is very troublesome and there is a problem that the work efficiency is low.

The present invention has been made to solve the above problems, and can firmly and stably hold the accelerator cable, and the carburetor of the carburetor can be held while two nuts are screwed to the holding metal fitting. The purpose of the present invention is to be mounted on a bracket, so that the throttle valve opening operation can be appropriately corresponded to the accelerator operation to cause the engine to perform a predetermined rotation, and the assembling can be simplified.

[0010]

SUMMARY OF THE INVENTION According to the present invention, an inner cable provided at the tip of an outer tube of an accelerator cable and connected to a throttle valve lever is inserted and extended, and two nuts are attached to a male thread on an outer peripheral surface. An accelerator cable holding device for a carburetor having a holding metal fitting screwed on the carburetor and a bracket for holding the accelerator cable provided on the carburetor in cooperation with two nuts to fix the holding metal fitting. It was decided to solve the above-mentioned problems as follows.

That is, the first means is that the outer tube and the holding metal member are fixed to each other, and the bracket has a recess opened on the peripheral side surface and a fitting groove opened on a different peripheral side surface. The fitting groove shall be fixed by fitting a metal mounting member that has a mounting groove open toward the open surface of the recess, and then insert the retaining bracket into the mounting groove from the open surface side to make the mounting member a recess. The accelerator cable is held by sandwiching and tightening it with a fitted nut.

By fitting the two nuts into the recess from the open surface side while screwing them into the holding metal fitting, the assembly is simplified and the work efficiency is improved, and the metal mounting member fitted and fixed in the bracket is attached. By pinching with a nut and fixing the holding metal fitting, there is no fear of loosening the nut tightening even if the bracket is made of synthetic resin.Furthermore, by fixing the holding metal fitting and the accelerator cable to each other,
The accelerator cable is firmly and stably held. Therefore, it is possible to achieve an object that the throttle valve opening operation can be appropriately corresponded to the accelerator operation to cause the engine to perform a predetermined rotation, and the assembling can be simplified.

A second means for solving the above-mentioned problem is that, in addition to screwing two nuts on the holding metal fitting, a spacer is fitted to the holding metal fitting so that the holding fitting is sandwiched between the two nuts. One of the two nuts fits in the empty space of the bracket, and the spacer fits in the other instead of the other of the two nuts, and the other nut cooperates with one nut outside the bracket. The accelerator cable is held by clamping the mounting member and the spacer by working.

In actual assembling, after setting the position of one of the nuts, the nut is overlaid on the mounting member and fitted into the recess,
Then turn the other nut to sandwich the mounting member,
It is desirable to follow this procedure. Therefore, the recess into which the turning nut fits is made to have a thickness that exposes a part of the nut, and there is no problem in strength when the bracket is made of metal. However, with the second means in which the nut is tightened outside the bracket using the spacer, the thickness of the recess into which the spacer is inserted can be increased to make the bracket thicker, so that the bracket made of synthetic resin has sufficient strength. It becomes possible to have.
