The quick joint structure for the metal hose structurally comprises a quick joint and a metal hose assembly, wherein the quick joint includes a first connecting pipe, a second connecting pipe, a connecting sleeve, an open clamp sleeve and a lock nut; the first connecting pipe is in threaded connection with one end of the connecting sleeve, and an inserting pipe is arranged at the other end of the connecting sleeve; compressed clamping teeth are uniformly distributed on the open clamp sleeve, locking frustums are arranged on all the compressed clamping teeth, and an annular conical surface matched with the locking frustums is arranged on an inner hole of the lock nut; the outer diameter of the second connecting pipe is matched with the inner diameter of the inserting pipe and the inner diameter of the open clamp sleeve, and the lock nut is in threaded connection with the inserting pipe. The quick joint structure for the metal hose has simple structure, compact appearance and low cost, has the characteristics of firm connection, high bearing capacity, durability, slipping-off prevention, looseness-prevention, non-leakage, convenience for maintenance and replacement, and the like in field use, and can be widely applied to the technology of connecting and matching the metal hose with technological equipment in the fields of petrochemistry, metallurgy, heat supply, and the like.
Description
Technical field
The utility model relates to a kind of quick connector structure that is used to connect metallic hose, belongs to the pipe fitting technical field.
Background technique
Metallic hose is to be used for replenishing or absorbing the elastic device because of physical descriptors such as pressure medium, temperature variation, pipe-line system vibrations as technological equipment or equipment connecting pipings technology.In realizing metallic hose and technological equipment or equipment pipeline connection procedure, adopt GB/T18615-2002 " corrugated flexible metal tube is with non-alloyed steel and stainless joint " or relevant flange standard piece more.These standard piece generally adopt the screw threads for fastening Placement.Special circumstances adopt pull-rod type rapid pipe joint or quick replacable type joint Placement.In the above-mentioned Placement, fastening piece connects not only wastes time and energy, and joint boundary dimension is bigger, receives the restriction of spatial position in the use, and fit sealing becomes the key technology that realizes connection again simultaneously.And in pull-rod type rapid pipe joint or quick replacable type joint Placement, pull-rod type quick joining type formula, though Placement is quick, because the pull bar size is bigger, the flexible pipe connection needs bigger spatial position, brings bigger economic waste for intensive process pipeline design.Though and quick replacable type joint Placement Placement is quick, manufacture cost is bigger, general 1/2 " its quick release coupling of flexible pipe exceeds flexible pipe price 2-3 doubly.
The model utility content
The utility model be used to solve the defective of above-mentioned prior art and provide a kind of and both satisfied quick connection request, economical and practical metallic hose is used the quick connector structure.
The alleged problem of the utility model solves through following technological scheme:
A kind of metallic hose is used the quick connector structure; By quick connector with form the metallic hose assembly parts that sealed-for-life is connected with it and form; Specialization is: said quick connector formation comprises first adapter, second adapter; Connecting sleeve, opening cutting ferrule and locking nut, said first adapter is connected with the connecting sleeve threaded one end, and the connecting sleeve the other end is provided with insertion pipe; Said open card puts and is uniformly distributed with the compression latch, and each compresses latch and is provided with the locking frustum, and the endoporus of said locking nut is provided with and locks the circular cone of frustum coupling; Said second adapter external diameter and insertion pipe internal diameter, opening cutting ferrule internal diameter size coupling, said locking nut is threaded with insertion pipe.
Above-mentioned metallic hose is used the quick connector structure, is provided with first seal ring between the said connecting sleeve and the first adapter end, is provided with second seal ring, the 3rd seal ring between insertion pipe end and each compressing card tooth ends.
Above-mentioned metallic hose is used the quick connector structure, and said compression latch inner end is provided with the stopping jump ring, and said opening cutting ferrule one end is provided with installing ring.
The utility model improves to hose coupling volume problem big, that cost is high, and a kind of quick connector structure that is used to connect metallic hose is provided.Said quick connector utilizes opening cutting ferrule attaching nut locking mechanism, can realize the connection of metallic hose efficiently.The utility model is simple in structure, compact appearance, cost are low, on-the-spot use have be connected firmly, bearing capacity height, durable anticreep, do not become flexible, characteristics such as ne-leakage, convenient maintenance and replacement.Can be widely used in the metallic hose and technological equipment or equipment connecting pipings technology in fields such as oil, petrochemical industry, metallurgy, building materials, heat supply.
