Description
Technical field
The utility model relates to a kind of quick connector structure that is used to connect rubber hose, belongs to the pipe fitting technical field.
Background technique
Rubber 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 rubber hose and technological equipment or equipment pipeline connection procedure, generally adopt JB1885 " A type fastening-pressing type rubber hose coupling ", JB/T6144.1 " awl sealed rubber pipe assembly welding tapered joint head ", JB/T6144.2 " awl sealed rubber pipe assembly straight pipe thread tapered joint head ", JB/T6144.3 " awl sealed rubber pipe assembly taper pipe thread tapered joint head " or relevant flange standard piece.These standard piece adopt the screw threads for fastening Placement usually, and special circumstances adopt pull-rod type rapid pipe joint or quick replacable type joint to connect.In the above-mentioned Placement, fastening piece connects wastes time and energy, and joint boundary dimension is bigger, tends to receive the restriction of spatial position in the use.Pull-rod type rapid pipe joint Placement is quick; But because the pull bar size is bigger; As: 1/2 " (12.7mm) flexible pipe, its pull bar boundary dimension reaches 68.4mm, is 5.38 times of flexible pipe latus rectum size; owing to need bigger spatial position, bring bigger economic waste for intensive process pipeline design.Though quick replacable type joint Placement connects quick, manufacture cost is higher, general 1/2 " price of its quick release coupling of flexible pipe is more than the twice of flexible pipe price.
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 rubber hose is used the quick connector structure.
The alleged problem of the utility model solves through following technological scheme:
A kind of rubber hose is used the quick connector structure; By quick connector with form the rubber 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 rubber 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 rubber 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 rubber hose is provided.Said quick connector utilizes opening cutting ferrule attaching nut locking mechanism, can realize the connection of rubber 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 rubber hose and technological equipment or equipment connecting pipings technology in fields such as oil, petrochemical industry, metallurgy, building materials, heat supply.
