CN204319089U - A kind of folding rod - Google Patents

Abstract

The utility model discloses a folding rod, which is composed of a left rod, a right rod and a hinged plate. The hinged plate has two side wings on the same side; Hinge holes; the right rod is hinged at the end of the hinge plate, the left rod ends between the two wings and hinged at the side wing hinge holes. The folding rod of the utility model is used as the cross bar of the folding stretcher. No matter what the operation is, the long rod of the stretcher will be on a plane, and the distance between the two rods is small after folding. After the stretcher is folded, the two long poles of the stretcher can be kept in good position, and the distance between the two long poles can be smaller than that of the prior art. After the stretcher is folded, the volume becomes smaller and the occupied space is smaller.

Description

a folding rod

technical field

The utility model relates to a connecting rod, in particular to a folding rod used for folding a stretcher.

Background technique

Existing folding rods, especially the folding bars used on folding stretchers, mostly use symmetrical folding methods, as shown in Figures 1 and 2, the folding rod is composed of two short rods and a hinged plate, and there are There are two hinged holes with symmetrical positions, and the two short rods are respectively hinged on the hinged holes with pin shafts. The two sides of this kind of folding pole are symmetrical in theory after folding, but it may not be possible to operate in this way when it is operated quickly in practice, and the long pole of the folding stretcher will be misplaced and uneven, and the distance between the two poles after folding is large, as shown in Figure 3 and 4 shown.

Utility model content

The technical problem to be solved by the utility model is to overcome the defects of the prior art and provide a folding rod for folding the stretcher. No matter what the operation is, the long rod of the stretcher will be on a plane, and the distance between the two rods after folding Small.

The utility model is a folding rod, which is composed of a left rod, a right rod and a hinged plate, and the hinged plate has two side wings on the same side; the feature is that each of the two side wings of the hinged plate is provided with a corresponding side wing hinge hole ; The right rod is hinged at the end of the hinge plate, and the end of the left rod is located between the two wings and is hinged on the hinge holes of the wings.

The folding rod of the utility model is used as the cross bar of the folding stretcher. No matter what the operation is, the long rod of the stretcher will be on a plane, and the distance between the two rods is small after folding.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figures 5 and 6, the folding rod is composed of a left rod 1, a right rod 2 and a hinge plate 3, and the hinge plate has two same-side wings 4; A side wing hinge hole 5 corresponding to a position; the right bar is hinged at the hinge plate end, and one end of the left bar is located between the two side wings and is hinged on the side wing hinge hole. The utility model is used as a cross bar of a folding stretcher. After the stretcher is folded, the two long bars of the stretcher can be kept in place, and the distance between the two long bars can be smaller than that of the prior art. After the stretcher is folded, the volume becomes smaller. Take up less space.
