Description

Technical Field

[0001] The utility model relates to the technical field of metal hoses, in particular to a metal hose which is easy to replace. Background Art

[0002] Metal hose is an important component of the connecting pipeline of modern industrial equipment. Metal hose is widely used in machinery, chemical industry, food, medical treatment and energy and other fields. It can be used as a protective tube for wires and cables, as a connecting element in various gas transmission systems, etc. It can also be used as a civilian rain hose, etc. Metal hose is generally composed of three parts: bellows, mesh sleeves and joints. According to the characteristics and uses of metal hoses, it can be divided into threading metal hoses, corrugated metal hoses and plastic-coated metal hoses.

[0003] The pipe bodies of existing metal hoses are mostly integral structures or welded connections. When a crack appears at one place on the pipe body, the entire pipe body will leak and cannot be used any further. The entire pipe body needs to be replaced, and the replaced pipe body can only be discarded or part of the metal can be recycled, resulting in a waste of resources. Therefore, a metal hose that is easy to replace is proposed to solve the above-mentioned problems. Utility Model Content

[0016] Since the first wedge block is matched with the second wedge block, the second wedge block can be pushed by the first wedge block to adjust the position, so as to facilitate the disassembly and replacement of the two sections of the hose body.

[0017] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0018] First, when the two sections of the hose body need to be connected, the first mounting ring on one section of the hose body is tightly attached to the second mounting ring on the other section of the hose body, and then the clamping ring on the clamping part is turned off from the clamping block to release the fixing effect of the clamping part on the clamping block. Under the elastic force of the first spring, the clamping block, the first slide plate, the connecting rod and the first wedge block are pulled into the second mounting ring, and the second wedge block is pushed into the second mounting ring. When the first wedge block moves to the farthest end, the second wedge block is reset under the elastic force of the second spring, and the first wedge block is clamped to the column to complete the connection of the two sections of the hose body.

[0019] Secondly, when the two ends of the hose body connected to the first need to be disassembled and replaced, the pull rod is pulled outward to move the second wedge block to the side away from the first wedge block, thereby releasing the fixing effect of the second wedge block on the first wedge block, and the first mounting ring can be pulled outward to achieve disassembly between the two sections of the hose body, and then the hose body can be replaced.
