Description

[Detailed Description of the Invention] This invention relates to a device for fixing a release wire for remote control in an accelerator lever of an engine.

Conventionally, the speed of engines mounted on working machines such as rice transplanters and binders is controlled remotely from near the operating handle of the working machine, so a release wire is used as the operating medium.
One end of the wire is connected to the engine's accelerator lever, and as part of this connection structure, a wire stopper is provided on the accelerator lever, and the inner wire is inserted through the through hole provided in this stopper, and the inner wire is passed through with a set screw. It was common to secure the hole by applying strong pressure to the center of the hole.

In this structure, the inner wire that is strongly pressed by the set screw is deformed into a concave shape or the twist is broken, making disassembly and reassembly difficult.

Moreover, it is difficult to screw in the set screw.

In other words, the accelerator lever, stopper, and inner wire must be held with the left hand while setting the set screw with the right hand, which is difficult to operate, making assembly work particularly difficult in a narrow space. Become.

In addition, one end of the accelerator lever is bent to form a wire fixing part, and the inner wire is held between this wire fixing part and a holding groove formed in a wire holding tool to which this screw is fixed. However, in this case, there is a problem that the wire fixing part begins to twist due to the operating force of the inner wire due to long-term use, and the engine rotation setting becomes deviated.

This idea attempts to solve the above-mentioned conventional drawbacks, and its feature is that the tip of the engine's accelerator lever is bent to form a wire fixing part, and the wire is fixed to this fixing part with a screw. The inner wire is held between the holding grooves formed in the wire holding tool, and a pair of position fixing/rotation prevention pieces are formed by bending both sides of the accelerator lever, and the holding grooves formed in the wire holding tool are held in both rotation stopper pieces. The point is that a pair of rotating front faces provided on both sides are fitted in a positioning manner to prevent rotation.

An embodiment of this invention will be described below based on the figures.

FIG. 1 is a plan view of a tilting engine mounted on a working machine such as a rice transplanter and remotely controlled, in which reference numeral 1 is the engine, 2 is a crankcase, and 3 is installed on the upper wall 2a of the crankcase 2. This device 3 connects an accelerator lever 4 made of sheet metal, a governor lever 5, a governor spring 6 that connects both levers 4 and 5, and a throttle lever 8 of a carburetor 7 to the governor lever 5. governor rod 9
It is composed of etc.

Reference numeral 10 denotes a tank stay fixed to the side wall 2bt of the crankcase 2, and a wire holder 10a for holding an outer case 11 of the release wire R is integrally formed with this.

FIG. 2 shows a plan view of the accelerator lever 4.
The base end thereof is horizontally swingably supported by a shaft 12, and a low speed adjustment screw 13 is installed at the middle part near the base end, and a metal fitting 14 for retaining the governor spring 6 is mounted at the middle part near the tip end. The wire fixing part 15 is formed by bending the tip end thereof at a right angle from the lever main body, and a male screw body insertion hole 16 is provided in the upper half of the rotating part 15.

FIG. 3 is a perspective view of the tip of the accelerator lever 4, in which a pair of position fixing/rotating pieces 17 are folded out from both side edges of the accelerator lever 4 at a portion close to the wire fixing part 15. There is.

Reference numeral 18 denotes a rectangular parallelepiped wire holding device, whose negative side is a joint surface 19, and a wire holding groove 20 is formed in the lower half of this surface 19.
is formed in a transverse shape, and a female thread 21 is transparently provided in the upper half thereof, and a pair of side surfaces located on both sides of the joint surface 19 of the wire presser 18 are used as rotation prevention surfaces 22.

The wire holding tool 18 is fitted into a space surrounded by the main body of the accelerator lever 4, the wire fixing part 15, and the position fixing/rotation stopper piece 17 in a positioning manner.
The joint surface 19 of the accelerator lever 4 comes into contact with the proximal side surface of the wire fixing part 15, the male threaded body insertion hole 16 and the female thread 21 match, and the left and right rotation prevention surfaces 22 are used to determine the left and right positions. It is locked by the stopper piece 17, and the lower surface 25 of the presser is received by the lever main body.

In this state, the wire presser 18 is pulled and fixed to the wire fixing part 15 by the male screw body 23 screwed into the female screw 21 through the male screw body insertion hole 16, and the wire presser groove 20 of the wire presser 18 and the wire Fixed part 15 and wire holder 1
The tip of the inner wire 24 extending from Oa is clamped and fixed.

Since the present invention is configured as described above, the inner wire 24 is simply clamped and fixed between the holding groove 20 and the fixing part 15, so deformation or twisting breakage of the inner wire 24 is prevented, and disassembly of the inner wire 24 is prevented. and reassembly is always easy.

In addition, the wire holding tool 18 has a position fixing/rotation stopper piece 17.
Since the wire holding device 18 is accurately positioned and reliably prevented from rotating, the wire holding device 18 can be easily, quickly, accurately, and strongly fixed to the wire fixing portion 15 with the male threaded body 23.

Furthermore, during this fixing operation, you only need to hold the screwdriver with one hand and tighten the male threaded body 23, and hold the inner wire 24 with the other hand, so the fixing operation can be performed easily and quickly, and the inner wire 24 can be tightened easily and accurately. It can be fixed strongly and can be easily worked even in narrow spaces.

Furthermore, in the present invention, a wire holding groove is formed below the threaded part of the holding tool, and a pair of position fixing and rotation preventing pieces are formed by pressing and bending both edges of the accelerator lever. As a result, the point where the inner wire operating force acts is located near the bending base end of the wire fixing part, which reduces the moment when the inner wire operating force tries to twist the wire fixing part, and it is integrated with the wire fixing part. Since the movement of the holding tool is stopped by the anti-rotation piece, twisting of the wire fixing part can be prevented.
