DESCRIPTION OF THE PREFERRED EMBODIMENTS According to a person skilled in the art in the art, other embodiments than those described below can be implemented without departing from the technical scope of the present invention. Is easy.

FIG. 1 shows a battery fixing structure according to the present invention. The battery 1 is disposed on a flat base 2 attached and fixed to a predetermined position of a general-purpose engine application device or a car by welding or bolting, and a clamp plate 7 disposed on the battery 1 and a pair of fixed support rods. 8 fixes it on the flat base 2. Thereafter, the electric power from the battery is distributed to various electric elements. Further, the legs of the flat base 1 are not always necessary. FIG. 2 is a partial cross-sectional view around the fixed support rod 8 on one side. The details of the battery fixing structure will be described with reference to FIGS. The pair of fixed support rods 8 pierce the left and right sides of the battery 1 with the U-shaped lower end portion 8-2 abutting on the lower surface of the flat base 2 and the latch portion 8-1 formed of a plurality of cutouts facing upward. Plane table 2
Are inserted into the pair of holes 2-1. The clamp plate 7
The pair of holes 7-1 are disposed on the upper portion of the battery 1 and are pushed down (toward the battery 1) in a state where each of the pair of holes 7-1 is engaged with the latch portion 8-1 formed of a plurality of cutout portions of each fixed support rod 8, and is clamped. The lower surface of the plate 7 is fixed in a state where it contacts the battery 1.

The clamp plate 7 is provided with a pair of tongues 10 which project into the pair of holes 7-1 so as to be slidable and engage with the latch 8-1 of the fixed support rod 8. The clamp plate 7 has a handle slide groove 7-2 near both ends and a tongue slide groove 7-3 below the handle slide groove 7-2. Tongue slide groove 7-3
Is open at the side of the hole 7-1 and closed at the other end. A spring 11 is arranged on the closed end side,
Thereafter, the tongue portion 10 is inserted into the tongue slide groove 7-3 with the R-shaped side of the pointed engagement portion 10-1 being the lower side, and then the handle 9 is moved from the handle slide groove 7-2 side.
The handle 9 is fixed on the tongue 10 by screwing, welding, bonding or the like. Therefore, the tongue portion 10 is slidably housed in the slide groove 7-3 in a state where the pointed engagement portion 10-1 protrudes into the hole 7-1 by the elastic force of the spring 11. By sliding the handle 9 toward the end of the plate 7, the engaging portion 1 at the tongue 10 is sharpened.
0-1 can move out of the hole 7-1.

Next, the latch engagement between the latch portion 8-1 and the tongue portion 10 of the fixed support rod 8 will be described. As shown in FIG. 2, each of the plurality of cutouts forming the latch unit 8-1 is horizontal on the upper side and R-shaped on the lower side. Tongue 10
The upper side is horizontal and the lower side has an R-shape similar to the pointed engagement portion 10-1, and is slidably housed in the tongue slide groove 7-3 of the plate 7 as described above. It is resilient in the direction.

Accordingly, when the plate 7 is pushed downward in FIG. 2, the tongue 10 generated by the contact force acting on each of the R-shaped portions of the latch portion 8-1 and the meshing portion 10-1 at the tip of the tongue 10 is displaced. The resilient force of the spring 11 cannot fully withstand the pushing force to the right in the drawing, and the tongue 10 is pushed to the right in the drawing, and the tongue 1
The meshing portion 10-1 at the zero point is moved into the hole 7-1. As a result, the plate 7 is pushed downward until the lower surface comes into contact with the battery 1, and the engaging portion 10-1 of the tongue 10 engages with the optimal latch portion 8-1. At this time, it is needless to say that the optimal engagement can be selected by the elastic deformation of the plate 7 made of a flexible material such as a metal such as iron or stainless steel or a plastic resin.

The R shape is for the purpose of generating a force for pushing the tongue portion 10 rightward in the drawing as described above, and other shapes for achieving this purpose are also possible. Similarly, the shape of the notch portion of the latch portion 8-1 and the shape of the meshing portion 10-1 at the tip of the tongue portion 10 need not necessarily be the same. The lifting of the plate 7 is achieved by sliding the handle 9 rightward in the drawing. In addition, plate 7
In the initial stage (when the insertion of the plate 7 into the fixed support bar 8 is started), the handle 9 is slid to the right in the drawing to engage the engaging portion 10-1 at the tip of the tongue 10 with the hole 7-1. Pushing work becomes easier by retreating from.

FIG. 3 shows a latch portion 8-1 of the fixing support rod 8.
Is shown. The latch portion 8-1 is configured by arranging a plurality of notches, each having a horizontal upper portion and an R-shaped lower portion, at predetermined intervals in the vertical direction in the circumferential direction. As shown in FIG. 2, the engagement portion 10 of the tongue 10
Each row is arranged stepwise so that the optimum meshing position with -1 can be selected in detail. In FIG. 3, the cutouts are arranged in steps of one notch. The rows shown in FIG. 3 are arranged in two rows at 90 ° intervals in the circumferential direction. This two-row arrangement at 90 ° intervals is the most effective and easy method for selecting an optimal meshing position, and is an arrangement that maintains the mechanical strength of the fixed support rods 8 made of metal such as iron most strongly. It is.

As shown in FIG. 2, the lower end 8-2 of the fixed support rod 8 is U-shaped, so that it can always contact the lower surface of the flat base 2 even when the fixed support rod 8 rotates. It is possible. The U-shape has another shape, V, that serves this purpose.
A letter shape, a flat shape, etc. are possible.

FIG. 4 shows another embodiment of the plate 7. On the lower surface side of the plate 7 contacting the battery 1,
An elastic material 12 such as a leaf spring, which is more flexible than the material forming the plate 7, is fixed by welding, bonding, screwing, or the like. At the time of contact with the battery 1, the elastic member 12 elastically deforms the latch portion 8-1 and the tongue portion 1 more easily and firmly.
A meshing position of 0 can be selected.

[0018]
