Connection brim for pipe nipple joint

Abstract

The invention provides a four-eye square joint connecting eaves which not only can be casted with the inner end of a pipe joint into a whole so as to form a complete square four-eye pipe joint, but also can be casted with one end or two ends of a short pipe so as to form a square eaves short pipe which is provided with four connecting eyes at one end or two ends for use of a water gate or a water pump; the connecting eaves can be also provided with an inner wire to form a separate unit, can be directly installed on the pipe for use, and suits for arbitrary selection according to respective different needs. The invention changes a four-eye circular joint connecting eaves into a four-eye square joint connecting eaves, has reasonable design, saves one or two times of raw materials, effectively reduces the production cost, avoids the waste of undeserved materials and funds, and has good social and economic benefits.

Description

Technical field: [0001] The invention relates to a pipe joint, in particular to a short pipe joint with four eyes, which simplifies the connection eaves. Background technique: [0002] The four-eye connecting eaves of the existing pipeline joints, including the sluice and the four-eye connecting eaves of the short pipe of the water pump, are all circular, especially on the agricultural water pump, there are many short pipes, many joints, and there are also many four-eye circular connecting eaves. There are more times of movement, frequent loading and unloading, and lifting. This kind of four-eye circular connecting eaves not only wastes raw materials, increases production costs, but also increases weight and labor intensity, which is cumbersome and laborious. Invention content: [0003] The purpose of the present invention is to provide a four-eye square joint connecting eaves that saves raw materials, reduces production costs, is small in size, light in weight, and durabl...
