[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operating rod for an automobile-mounted jack, and to a split type jack operating rod.

[0002]

2. Description of the Related Art Conventionally, there has been an operation rod of a jack which is divided to facilitate loading when mounted on an automobile. However, when connecting when using this, as shown in FIG. 1, the joint portion of the operating rod 1 has an insertion portion 2 on the insertion side for transmitting a rotational force, and a fitting portion corresponding thereto. Three
After each of them is formed into a square shape and further fitted and connected, the screw rod 5 is screwed into the screw hole 4 provided on the fitting portion 3 side so that the insertion portion does not come off, and the insertion portion 2 side inserted It is generally known that the screws are tightened and pressed.

[0003]

The problem to be solved is that, as described above, in order to connect and connect the split operation rods, not only a tool is required for screwing but also a time is required before use. It was necessary and wasted.

[0004]

SUMMARY OF THE INVENTION In the present invention, the fitting portions facing the divided operating rods, the fitting portions for fitting the one insertion portion side and the other insertion portion are respectively formed into a horn shape, and further, the ridge portion Each one surface is provided with an engaging hole that overlaps when fitted, and further, on one fitting portion side, a claw piece provided with an inclined portion is provided at the tip,
The proximal end side of the elastic locking piece for positioning the claw portion in the engaging hole is attached, and the operating piece for disengaging the claw portion from the engaging hole is integrally provided on the locking piece. It is intended to provide a split type operation rod.

[0005]

According to the present invention, in order to connect the divided connecting portions A, when the insertion portion 12 of the operating rod body 11 is inserted into the fitting portion 13 of the opposing operating rod body 11, the tip of the insertion portion 12 is fitted. The slanted portion 17 of the claw portion 16a of the locking piece 16 attached to the portion 13 side
Push up and insert it further to engage the engaging hole 1 provided in the insertion part 12.
When 4 is aligned with the claw piece 16a, the claw piece 16a is locked by the locking piece 16a.
By the repulsive force of the elastic action, the fitting portion 14 is fitted and locked in the engagement hole 14 to prevent the insertion portion 12 from coming off the fitting portion 13.

When it is desired to pull out the insertion portion 12 inserted into the fitting portion 13 and locked, the actuating piece 16c of the locking piece 16 attached to the fitting portion 3 side is pressed, whereby
The locking piece 16 is pushed up elastically around the protrusion of the locking piece 16 and the claw portion 16a at the tip is removed from the engagement hole 14. Thereby, the insertion part 12 fitted in the fitting part 13 can be separated.

1 shows an embodiment of a split type jack operating rod according to the present invention. An embodiment of the present invention will be described below with reference to this drawing.

Reference numeral 11 is an operation rod body, which is provided with a hook portion 11a for engaging with a driving ring provided on the jack drive shaft at one end and a corner portion 11b for fitting a handle at the other end, and is separable in the middle portion. I am doing it.

The separable connecting portion A of the intermediate portion has an insert portion 12 formed at a corner on one side and a fitting portion 13 of a square hole into which the insert portion 12 is fitted, on the other side. There is.

Engagement holes 14 and 15 are formed on one surface of the insertion portion 12 and the fitting portion 13 so as to overlap each other at the time of fitting, and a locking piece 16 attached to the operation rod body 11 on the fitting portion 13 side.
The claw portion 16a provided at the tip of is inserted and locked in the pulling direction of the insertion portion 12 of the operation rod body 11 at the time of connection.

The locking piece 16 is made of synthetic resin, a metal plate or the like and has elasticity to some extent, and the tip claw piece 16a is provided with an inclined portion 17 to engage the insertion section 12 when the claw piece 16a is fitted. When the hole 14 coincides with the claw portion 16a, the claw portion 16a is engaged with the engaging hole 1
It is automatically fitted into 4. Further, the other end of the locking piece 16 is integrally provided with a protrusion 19 for preventing movement to be fitted into a hole 18 formed in the fitting portion 13 side of the operation rod body 11 and surrounding pieces 16b, 16b provided in the left-right direction. Further, the locking piece 16 is provided with an operating piece 16c extending from the intermediate portion toward the base end side, and the operating piece 16c is pressed to lock the locking piece 16 around the protrusion 19. 16a provided on the
The tip of the is removed from the engagement hole 14.

[0012]

[Effect of the Invention] Since the present invention is configured as described above,
With the operation rod of the jack that is divided into automobiles, simply insert the insertion part of the operation rod body into the fitting side, and the claw piece of the locking piece attached to the fitting side will automatically fit into the engagement hole of the insertion part. If you want to separate it, and you want to separate it, you can easily separate it by pressing the operating piece provided on the locking piece and pulling out the claw piece from the engaging hole of the insertion part and disconnecting it without using a tool. There is an effect that it can be done with one touch and wasteful time can be saved.
