Anti-disengaging safety device for high pressure hose

Abstract

The invention discloses an anti-disengaging safety device for a high pressure hose. The anti-disengaging safety device comprises a high pressure joint and the high pressure hose installed on the high pressure joint. The high pressure joint is provided with a fixing assembly. The fixing assembly comprises a first clamp nut, a fixing plate, a second clamp nut and a joint body which are sequentially connected. A first buckle is arranged below the fixing plate. The high pressure hose is provided with a rubber protecting ring, and the rubber protecting ring is of an annular groove structure encircled by two rubber flanges. A clamping sleeve is arranged in the rubber protecting ring in a matched mode. A connecting plate is arranged below the clamping sleeve. The connecting plate is further provided with a second buckle, and the second buckle is connected with the first buckle through a stainless steel wire rope. By the adoption of the anti-disengaging safety device, 'whipping harm' to people or objects around by the high pressure hose in the disengaging process can be prevented, fastening performance is good, and safety is high; different fixing modes can be selected according to the practical situations; the hose is provided with the rubber protecting ring, damage to the outer surface of the hose by the clamping sleeve can be better prevented, the service life of the hose can be better prolonged, and the anti-disengaging performance is enhanced.

Description

technical field [0001] The invention relates to the field of hydraulic machinery, in particular to a high-pressure rubber hose safety device for preventing collapse. Background technique [0002] In the traditional hydraulic system, the connection of hydraulic hoses is usually fixed by clamps or some simple strapping methods, and the hydraulic hoses may fall off or collapse during use. Due to the excessive pressure in the hydraulic hose, at the moment when the hose is separated from the sleeve, the internal high-pressure medium makes the detached hose full of force and speed, and the high-pressure medium is ejected from the hose, and the hose begins to release the capacity inside, instantly producing a very Fast speed, triggering a dangerous "whip damage", which is very dangerous to people or things around you. [0003] Patent application number: 201220395212.0 discloses a high-pressure hose fall-off prevention device, which includes a hose clamp and a fixing plate, and is ...
