A reusable high-pressure hose connector

Abstract

This utility model relates to the field of hose connector technology, and more particularly to a reusable high-pressure hose connector, comprising a first connecting tube, a left connector connected to the right side of the first connecting tube, a right connector threaded to the right side of the left connector, and a second connecting tube connected to the right side of the right connector. The first connecting tube includes a first pipe and a groove formed on the outside of the first pipe. The left connector includes a left connector body, a threaded sleeve fixedly connected to the right side of the left connector body, and a fixing sleeve fixedly connected to the right side of the left connector body. When the left and right connectors are rotated together, the tight contact of multiple threads and the engagement of the fixing sleeve together form the main sealing layer. Simultaneously, the engagement of the fixing ring and the groove provides initial fixation to prevent displacement. The connecting tube can be cut as needed and positioned through the groove. Cable ties further reinforce the external connection, increasing the airtightness of the pipe and preventing the connector from detaching from the pipe under high pressure.

Description

Technical Field

[0001] This utility model relates to the field of hose fitting technology, specifically a reusable high-pressure hose fitting. Background Technology

[0002] High-pressure hoses are pipelines used in hydraulic systems of mine hydraulic supports, oilfield development, engineering construction, lifting and transportation, metallurgical forging, mining equipment, ships, injection molding machinery, agricultural machinery, various machine tools, and mechanized and automated hydraulic systems of various industrial sectors to transport petroleum-based (such as mineral oil, soluble oil, hydraulic oil, fuel oil, lubricating oil) and water-based liquids (such as emulsions, oil-water emulsions, and water) with certain pressure and temperature.

[0003] Most high-pressure hoses currently available have length requirements during installation. The hoses need to be pre-cut to the required length before being used with connectors. The length cannot be flexibly changed according to site requirements, resulting in reduced construction efficiency and limited applicability. Utility Model Content

[0004] To overcome the problem that most high-pressure hoses currently have length requirements during installation, which cannot be flexibly changed according to site requirements, resulting in reduced construction efficiency and harsh applicable scenarios.

[0005] The present invention is as follows: a reusable high-pressure hose connector, comprising a first connecting tube, a left connector connected to the right side of the first connecting tube, a right connector threaded to the right side of the left connector, and a second connecting tube connected to the right side of the right connector.

[0006] The connecting pipe includes a pipe and a groove formed on the outside of the pipe.

[0007] The left connector includes a left connector body, a threaded sleeve fixedly connected to the right side of the left connector body, a fixed sleeve fixedly connected to the right side of the left connector body, a fixed groove opened on the outside of the left connector body, and a fixed ring fixedly connected to the inside of the left connector body.

[0008] The right connector includes a right connector body, a threaded groove on the left side of the right connector body, a fixing groove on the outside of the right connector body, and a fixing ring fixedly connected to the outside of the right connector body.

[0009] The connecting pipe 2 includes a pipe 2 and a groove 2 opened on the outside of the pipe 2.

[0010] Preferably, the first fixing groove is located on the outside of the connection between the first fixing ring and the left connector body, and the second fixing groove is located on the outside of the connection between the second fixing ring and the right connector body.

[0011] Preferably, the threaded sleeve is threadedly connected to the threaded groove.

[0012] Preferably, the fixing sleeve is fitted into the right connector body.

[0013] Preferably, the outer sides of the connecting pipe one and the connecting pipe two are provided with a plurality of grooves one and two at fixed intervals.

[0014] Preferably, the connecting pipe 1 and the left connector 2 are connected to the right connector 3 and the connecting pipe 4.

[0015] Compared with the prior art, this utility model provides a reusable high-pressure hose connector, which has the following beneficial effects:

[0016] 1. When the left and right joints are rotated and connected, the tight contact of multiple threads and the fitting of the fixing sleeve together form the main sealing layer. At the same time, the locking of the fixing ring and the groove provides initial fixation to prevent displacement. The connecting pipe can be cut according to requirements and positioned through the groove. The cable tie further strengthens the external connection, increases the airtightness of the pipe, and prevents the joint from falling off the pipe under high pressure.

[0017] 2. This utility model achieves quick assembly and disassembly through the precise thread engagement of the left and right connectors. The fitting structure of the fixing sleeve and the right connector body effectively minimizes gaps, avoids liquid leakage caused by reduced air tightness, and ensures air tightness under high pressure. The groove on the outside of the connecting pipe engages with the fixing ring to form a double positioning. With the help of cable ties, it can prevent vibration from loosening. The overall through channel ensures the continuity of medium flow. Attached Figure Description
