hose clamp

Abstract

A hose clamp comprises a roughly circular clamp body (1) which is formed integrally by a resin and in a ring body shape with a part cut away, and a bar part (2) which is connected with end parts of notches of the clamp body (1). The bar part (2) comprises a first moving piece (3) and a second moving piece (4), wherein the first moving piece (3) is rotationally connected with the end part of a square notch of the clamp body (1) through a first hinge part (6); a clamping part (5) is arranged at the top of the first moving piece (3); the second moving piece (4) is rotationally connected with the end part of another square notch of the clamp body (1) through a second hinge part (6); the top end of the second moving piece (4) is connected with the first moving piece (3); and a clamped part (8) corresponding to the clamping part (5) is formed on the periphery of the clamp body (1). The hose clamp is low in manufacturing cost and can fix a hose tightly and rapidly.

Description

technical field [0001] The invention relates to a hose clamp for fastening and fixing a hose connection part from the outside. Background technique [0002] Conventionally, there is known a hose clamp that fastens and fixes a hose connection portion using the principle of leverage. For example, the hose clamp disclosed in Patent Document 1 has a structure in which both ends of an elongated thin steel plate are transition-fitted to form a substantially annular shape, and a rod is integrally fixed to the transition-fit portion. The rod is pushed down toward the outer periphery of the ring-shaped clip body, so that the inner diameter of the clip body is reduced by the action of the lever, and the hose inserted inside is clamped. However, there is a problem that since the hose clamp has a structure in which a thin steel plate is transition-fitted and bent, a large load must be applied to push down the rod formed in the transition-fit portion, resulting in poor operability. In ...

AI Technical Summary

Problems solved by technology

However, there is a problem that since this hose clamp is a structure in which a thin steel plate is transition-fitted and bent, it is necessary to apply a large load to push down the rod formed on the transition-fit portion, and the operability is poor.

In addition, there is also the following problem: it is necessary to additionally weld the fasteners used to prevent the rod from being lifted after being pushed down, and the manufacturing cost is high

However, in the locking of the hose clamp, it is necessary to follow the two steps of first hooking the top end of the action piece on the fastener, and then pressing down the other end of the action piece, and the locking takes time.
