Abstract
The utility model discloses a hose connector, which comprises two nuts and a short tube (1), wherein the nuts are sleeved at ends of a hose to be butted respectively. A stepped hole with an internal thread is arranged in the center of each nut, the hole diameter of the large stepped hole is consistent with the outer diameter of the hose, and the hole diameter of the small stepped hole is consistent with the inner diameter of the hose. Two ends of the short tube (1) are inserted into the nuts (2) on two sides and the ends of the hose to be butted respectively, conical chamfers are arranged at the two ends of the short tube (1), and a thread matched with a thread of the small stepped hole is arranged outside the short tube (1). The space between air hoses is sealed by means of threaded compression, and the hose connector has the advantage of high sealability. Moreover, sealing can be realized only by screwing screws during installation, and the hose connector is convenient in replacement and simple in operation.
Description
Technical field
Structure when the present invention relates to the butt joint of a kind of flexible pipe in particular, relates in the shipbuilding process as joint structure that wind band flexible pipe docks.
Background technique
Often use hose construction in the work items, particularly shipbuilding project, like wind band flexible pipe etc.Because wind band flexible pipe fracture or the not enough situation of length occur through regular meeting, if fracture just need be carried out the connection of breaks, if length also need look for a wind band flexible pipe to connect inadequately in addition.Often the connection of wind band flexible pipe does not have a kind of joint of fine form, much all is simply copper pipe to be connected end to be inserted in the inner diameter of two butt joints, uses the iron wire tighten then.
Problem is that not only complicated operation, and sealability is not good.The connection pattern of existing technology particularly, iron wire twines flexible pipe and seals, and the long-time back iron wire that uses is loosening easily, can't reach sealing effect, and change pretty troublesome.
Summary of the invention
The present invention aims to provide a kind of flexible pipe docking structure of simple to operate, good seal performance.
In order to achieve the above object, the present invention provides a kind of hose coupling, comprises that two are socketed in the nut of waiting to dock hose respectively, and the center of said nut is the shoulder hole that is provided with internal thread; Wherein, The aperture at big shoulder hole place is consistent with the external diameter of said flexible pipe; The aperture at little shoulder hole place is consistent with the internal diameter of said flexible pipe, thereby makes said flexible pipe penetrate and the end leans in said little shoulder hole one side from said big shoulder hole one side. said hose coupling also comprise two ends peg graft respectively the said nut in both sides with wait to dock the short tube of hose; The two ends of said short tube are provided with the taper chamfering, and said short tube outside is provided with the screw thread with said little shoulder hole screw-thread fit, thereby the end of said short tube is passed the little ladder nose end of said nut respectively earlier and is plugged in the said hose internal diameter.
Under the optimal way, the screw thread at two the medium and small shoulder hole of nut places is the opposite way setting.
Joint of the present invention is to utilize form that screw thread compresses to sealing between wind band flexible pipe, has the high characteristics of sealing, and only needs when installing furbuckles just can reach the effect of sealing, changes to make things convenient for, and is simple to operate.

Fig. 2 is the nut structure schematic representation that uses in the hose coupling of the present invention.
Embodiment
A kind of wind band flexible pipe that is used for connects and to use novel joint, and the screw thread squeezing tube plays seal action.Specifically, joint form is made up of two nuts and the threaded short tube in outside.Wherein require the internal diameter of nut identical, and the upper end is threaded with the external diameter of wind band flexible pipe.The screw thread of short tube is identical with the screw thread of nut upper end, and the short tube end will have tapering chamfering (tapering is preferably 1: 2, and tapering is meant the bottom surface diameter of circular cone and the ratio of vertebral height), and the external diameter of short tube is identical with the internal diameter of wind band flexible pipe.The band flexible pipe of keeping watch earlier during use is inserted in the nut, is inserted into the short tube end in the internal diameter of wind band because short tube has tapering again, tightens then, and short tube will push the effect that wind band flexible pipe reaches sealing like this.
Nut 2 is as shown in Figure 2: require the bore of C place screw thread identical with the external diameter of flexible pipe, the external diameter of B place screw thread is identical with the internal diameter of flexible pipe.It is left-hand thread that another nut requires B place screw thread.(left-hand thread is meant: general nut all is to be meant counterclockwise to tightening for tightening left-hand thread clockwise.)
Short tube 1 is as shown in Figure 1: require the size of A place screw thread identical with nut B place screw thread, and the end has the tapering chamfering.
Placement does, the wind band flexible pipe that two needs are connected inserts respectively in two nuts, and attention must be inserted into the bottom of nut; Then short tube is inserted into respectively in two nuts; So be easy to insert in the internal diameter of flexible pipe because the two ends of short tube have tapering, hold two nuts with hexagon wrench then and tighten, so just let short tube constantly insert in the internal diameter of wind band flexible pipe; Be easy to expand after should be flexible being squeezed of wind band flexible pipe, thereby reach the effect of sealing.C place screw thread in the nut also can play the effect that can not let wind band flexible pipe come off simultaneously.Thereby the present invention can reliably connect wind band flexible pipe, and reaches good sealing effect.
The above; Be merely the preferable embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any technician who is familiar with the present technique field is equal to replacement or change according to technological scheme of the present invention and inventive concept thereof in the technical scope that the present invention discloses, all should be encompassed within protection scope of the present invention.
Claims (2)
1. a hose coupling is characterized in that, comprises that two are socketed in the nut (2) of waiting to dock hose respectively, and the center of said nut (2) is the shoulder hole that is provided with internal thread; Wherein, the aperture at big shoulder hole place is consistent with the external diameter of said flexible pipe, and the aperture at little shoulder hole place is consistent with the internal diameter of said flexible pipe, thereby makes said flexible pipe penetrate and the end leans in said little shoulder hole one side from said big shoulder hole one side;
Said hose coupling also comprises peg graft respectively said nuts in both sides (2) and wait to dock the short tube (1) of hose of two ends; The two ends of said short tube (1) are provided with the taper chamfering; Said short tube (1) outside is provided with the screw thread with said little shoulder hole screw-thread fit, thereby the end of said short tube (1) is passed the little ladder nose end of said nut (2) respectively earlier and is plugged in the said hose internal diameter.
2. according to the said hose coupling of claim 1, it is characterized in that the screw thread at the medium and small shoulder hole of two nuts (2) place is the opposite way setting.
