Problems solved by technology

[0002] In our real life, there are some situations that require longer rods, such as the folding ladders that firefighters need when performing tasks, and in some actual working conditions that require relatively long straight rods or angled curved rods, but Such tools are inconvenient to carry and are easily crushed
[0003] Usually, the long rod can be made telescopic, such as the teacher's teaching aid indicator rod, but this method is only suitable for such a hollow and almost without any load. it's not reasonable

Embodiment Construction

[0026] In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.

[0027] like Figure 1~10 As shown, a simple adjustable angle hinge includes an inner link plate 1 and an outer link plate 2 hinged to each other. The outer link plate has several outer positioning holes distributed on the outer circumference of the hinge point, and the inner link plate is located at the hinge point. The outer periphery is provided with an inner positioning hole 3, and the inner chain plate and the outer chain plate are rotated and limited by the positioning pin 4 passing through the outer positioning hole and the inner positioning hole.

[0028] In the embodiment of the present invention, the shape of the hinge end of the outer link plate is "U" shape, that is, there is a notch 15 for inserting the hinge end of the inner link plate, and the wid...

Abstract

The invention relates to a simple angle adjustable hinge. The simple angle adjustable hinge comprises an inner chain plate and an outer chain plate which are hinged. A plurality of outer locating holes are distributed on the periphery of the hinge point of the outer chain plate in the circumferential direction. Inner locating holes are arranged on the periphery of the hinge point of the inner chain plate. The inner chain plate and the outer chain pale are subjected to rotation limiting through locating pins penetrating through the outer locating holes and the inner locating holes. The simple angle adjustable hinge is simple in structure.

Description

technical field [0001] The invention relates to a simple adjustable angle hinge and its working method. Background technique [0002] In our real life, there are some situations that require longer rods, such as the folding ladders that firefighters need when performing tasks, and in some actual working conditions that require relatively long straight rods or angled curved rods, but Such tools are inconvenient to carry and are easily crushed. [0003] Usually, the long rod can be made telescopic, such as the teacher's teaching aid indicator rod, but this method is only suitable for such a hollow and almost without any load. It is not reasonable. Contents of the invention [0004] In view of the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a simple adjustable angle hinge and its working method. [0005] In order to solve the above technical problems, the technical solution of the present invention is: a simple a...
