Lever-type rapid connection method for flexible pipes

Abstract

This invention is one kind is suitable for each hose release lever momentary connection method. Is realizes the hose momentary connection structure through a crank release lever leverage, including the crank release lever, the tension bar, the spindle, pulls mandrel, the fitting main body, locks the band, the locator card. States the crank release lever, the tension bar, the spindle is leaves the plant when the product already the necessary assembly on the fitting main body, installs when first will lock the band set to the hose reason, then will insert this hose reason to the fitting main body cone bell and spigot joint on, and will insert the root, will pull locks the band also to wrap to the fitting main body cone bell and spigot joint on, will tighten the tension bar front end Kong Koutao to to pull mandrel on, will move the crank release lever, will cause its side to give instead of taking attaches to the fitting main body on, the rotation locator card, will suppress the crank release lever to cause its not to have to move. This invention uses in the hose release lever type momentary connection method to be able to each kind of hose realization momentary connection. Installs the use extremely to facilitate quickly, saves the time, does not need any construction machines and tools equipment, only must gently as soon as move the bar with the hand lever handle, then realizes the very ideal hose connection, also the connection quality is good, also leakproof, may realize to each kind of hose momentary connection, especially is suitable to the field operation military temporary pipeline lays down. Because it installs and disassembles similarly is all convenient, its may repeatedly use.

Description

technical field

[0001] The invention relates to a pipeline fitting, in particular to a lever type quick connection method for a hose. Background technique

[0002] In practical applications, hoses are used in many places, because they are convenient, can be bent and wound arbitrarily, so the market demand for hoses is very large. There are four main types of hoses: rubber hoses, plastic hoses, Cloth pipe, wire hose. Among them, cloth pipes such as asbestos cloth pipes for fire protection applications are of fixed length, and there are clamping aluminum alloy connectors fixed on both ends of the pipe; metal wire hoses are also of fixed length in the market, and both ends are also fixed. on the connector above. The connection methods on these two kinds of pipes are not suitable for popularization and application to the connection of various hoses. Rubber tubes and plastic hoses are the most widely used in the market, but so far there is still no pipe fittings that can be fr...
