Easy-to-install hydraulic hose connector for engineering machinery

Abstract

The invention discloses an easy-to-install hydraulic hose connector for engineering machinery. The connector comprises an inner sleeve, a connector outer sleeve is in threaded connection with the outer circumferential side face, close to the right end, of the inner sleeve, and an annular hose inserting groove is formed between the connector outer sleeve and the inner sleeve; an annular cutting groove is formed in the inner side wall of the inner sleeve, multiple notches are evenly formed in the side wall of the inner sleeve in the circumferential direction at intervals, the notches communicatewith the hose inserting groove and the annular cutting groove, and the notches are located in the left end of the annular cutting groove; a pressing block is slidably connected in each notch in the radial direction of the inner sleeve, a moving hose is in threaded connection with an opening in the right end of the annular cutting groove, and the left end of the moving hose extends into the annular cutting groove and is used for controlling the pressing blocks to extend into the hose inserting groove from the notches; and the right end of the moving hose is sleeved with a hose connector nut. The hydraulic rubber hose connector is simple in structure and capable of facilitating connection between a high-pressure hose and the connector.

Description

technical field [0001] The invention belongs to the technical field of hydraulic accessories, in particular to a hydraulic pipe joint. Background technique [0002] At present, in the hydraulic system, hydraulic hoses are the most used when connecting the oil passages between various components, because the existing hydraulic hoses are made by crimping the buckle-type hose joints and the high-pressure hose connection ends. , The length of the high-pressure hose cannot be changed after the production is completed. In order to avoid the length of the hydraulic system pipeline, before the hydraulic system is connected to the pipeline, it is necessary to determine the length of the pipeline according to the distance between the components, and customize the hydraulic hose manufacturer according to the length. Hydraulic hoses will affect the assembly process of the hydraulic system during the piping process of the hydraulic system, delaying the construction period, and if there a...

[0002] At present, in the hydraulic system, hydraulic hoses are the most used when connecting the oil passages between various components, because the existing hydraulic hoses are made by crimping the buckle-type hose joints and the high-pressure hose connection ends. , The length of the high-pressure hose cannot be changed after the production is completed. In order to avoid the length of the hydraulic system pipeline, before the hydraulic system is connected to the pipeline, it is necessary to determine the length of the pipeline according to the distance between the components, and customize the hydraulic hose manufacturer according to the length. Hydraulic hoses will affect the assembly process of the hydraulic system during the piping process of the hydraulic system, delaying the construction period, and if there are errors in size measurement, the customized hydraulic hoses may not be used, which will cause waste; during the use of hydraulic hoses , the connection between the high-pressure hose and the buckle-type joint is prone to damage and leakage, so the entire hose can only be discarded as scrap, causing a lot of waste and bringing inconvenience to production and life
