Groove type wedged surface interface

Abstract

The invention discloses a groove type wedged surface interface. The groove type wedged surface interface comprises a pair of relatively arranged connection bodies, detachable hoop embracing assemblesare separately arranged on the connection bodies, and detachable connection assemblies are arranged at the connection positions of the connection bodies. The connection bodies comprise cylindrical connection cylinder bodies and annular connection ring bodies, the hoop embracing assemblies comprise a plurality of tile-shaped hoop piece units, and the connection assemblies comprise a pair of detachable connection units and a pair of sealing rubber rings. The groove type wedged surface interface is convenient to install, and the difficult problem that correct installation in the field environmentof a C-type sealing ring is difficult is solved by adopting the mode of wedged surface tightening. Only two connection bodies is required to be aligned, and the connection bodies fall into a groove without compression due to the large opening of the wedged surface. Only tightening a bolt and tightening a gap are required, the sealing rubber rings of the end surface can play the compression effect, and the assembly efficiency of the site is greatly improved.

Description

technical field [0001] The invention relates to a hose connector, more precisely, a grooved wedge interface. Background technique [0002] Most of the domestic traditional hose joints are German-style standard buckle claw joints. The main structure is German-style body, end face sealing ring, German-style buckle body, hoop, clamp spring, etc., which are widely used in small-caliber, while large-caliber Due to the large cross-sectional area of ​​the claw, the pressure it can withstand is not large, usually no more than 10 kg. And in the process of installation and use, the sudden increase in water pressure may cause damage to the product; in addition, because the three claws are easy to operate improperly during use, and collide with the ground or hard objects, resulting in relatively high damage to the three claws. Large stress, it may not break on the spot, but there are hidden dangers under water pressure. [0003] The grooved interface is mainly used abroad, and the mai...

AI Technical Summary

Problems solved by technology

This structure has been used for a long time, and its reliability has been verified; the disadvantage is that when the two bodies are docked in the field, it is difficult to install the C-shaped sealing ring correctly. Secondly, when the clamp bolts are tightened, the bottom of the clamp is difficult. It fits into the groove of the groove body, and even if it can be assembled correctly, the size of the bottom of the clamp entering the groove of the body is short, and the contact length does not exceed 2mm. When the bending radius is large, the strength of the clamp is sufficient, and due to the contact area When the bending radius is small, the aluminum alloy body will be strained and damaged, and the clamp will fall off from the groove of the body, resulting in fluid leakage, and serious injury accidents
