Table isoline connects, and type of attachment has socket weld or threaded connection, is mainly used for small-bore low-pressure line, needs often assembly and disassembly
Position or be used as the final adjustment using threaded fitting pipeline.According to the difference of use environment, need to use different materials
The connector of material, and for Korrosionsmedium, it is also necessary to consider the factors such as the material of sealing, and common connector meets at all
Not these requirements.In addition, similar product on the market at present, the defects of because in structure design, in the construction process, it is necessary to two
The both ends of a or multiple worker's cooperations while fixed -piping could complete, and which adds artificial inputs, increase installation
Cost, while to the technology requirement of construction personnel and installation accuracy higher.
Utility model content
In order to solve the shortcoming present in above-mentioned technology, the utility model provides a kind of fast twist-on head of stainless steel.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of fast twist-on head of stainless steel, bag
Include fixed card buckle, cutting ferrule nut, O-ring；Fixed card buckle is hollow hexahedron, and fixed card buckle is internally provided with O-ring, fixes
The both ends of buckle are both provided with directly to silk；It is directly logical by threaded engagement, the other end with fixed card buckle to one end of silk
Cutting ferrule is crossed with cutting ferrule nut thread to connect；
Cutting ferrule carries the becket of cutting edge for one side, and the left end of cutting ferrule is circular ring shape, right end is cone, and cutting ferrule is pressed from a left side
Axial movement to the right connects with cutting ferrule nut.
It is silk outside both ends directly to silk.
Cutting ferrule nut is hex nut.
Cutting ferrule nut fastens with cutting ferrule.
The utility model offer is a kind of to be not only not required instrument but also can realize the stainless steel joint for pipeline dismounted rapidly, structure letter
List, installation and removal speed are fast, easy to operate, can match somebody with somebody three-way elbow, four-way, five logical uses, can be widely applied to various fluids
In delivery pipeline system.

Fig. 2 is the decomposition texture schematic diagram of Fig. 1.
In figure：1st, O-ring；2nd, cutting ferrule；3rd, cutting ferrule nut；4th, fixed card buckle；5th, directly to silk.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
The fast twist-on head of a kind of stainless steel as shown in Figure 1 and Figure 2, including fixed card buckle 4, cutting ferrule nut 3, O-ring 1；It is fixed
Buckle 4 is hollow hexahedron, and fixed card buckle 4 is internally provided with O-ring 1, and the both ends of fixed card buckle 4 are both provided with directly to silk
5；Cutting ferrule 2 and 3 screw thread phase of cutting ferrule nut are directly passed through by threaded engagement, the other end with fixed card buckle 4 to one end of silk 5
It connects；It is silk outside both ends directly to silk 5.Directly to the outer silk size of silk 5 according to used in determining the size of institute's connecting pipe.It will
Prevent hard foreign matter from passing in and out fixed card buckle 4, directly to the inside of silk 5, in order to avoid cause the damage of component.Fixed card buckle 4 is as company
Body is carried, is acted synergistically with each component, for connecting the pipelines such as three-way elbow, four-way.Cutting ferrule 2, cutting ferrule nut 3, fixed card buckle
4th, it is stainless steel directly to the material of silk 5.
Cutting ferrule 2 carries the becket of cutting edge for one side, and the left end of cutting ferrule 2 is circular ring shape, right end is cone, and cutting ferrule 2 is pressed
Axial movement from left to right connects with cutting ferrule nut 3；Cutting ferrule nut 3 fastens with cutting ferrule 2.Cutting ferrule 2 is simple in structure, leakproofness
Can reliable, easy to use, shape it is light and handy it is beautiful, without encrypt seal, without welding, saving material, to assemble and disassemble performance repeatedly good.Card
Set 2 does not have to welding, so as to reduce influence of the pipeline impurity to system performance.Cutting ferrule nut 3 is hex nut.
O-ring when mounted, answers symmetrical screwing screw, must not be screwed by direction order.The material of O-ring 1 is the fine rubber of fourth
Glue or fluorubber.O-ring 1 is most popular a kind of sealing element in hydraulic and pneumatic transmission system.O-ring 1 is suitble to a variety of
Seal form, multi-motion mode and a variety of different sealing mediums, and design simply, compact structure is convenient to mount and dismount, material
It is wide in variety, at low cost.
The specific connection mode of the utility model is：By taking the connection of pipeline and three-way elbow as an example, by cutting ferrule nut 3, card
Set 2 is nested with successively in pipeline one end that needs connect, in the case where playing the axial action of cutting ferrule nut 3 of pressuring action, along pipeline
Axial movement, while the cutting edge end of cutting ferrule 2 generates radial contraction under radial effect, between eliminating between cutting ferrule 2 and pipeline
Gap, and make the edge contacts pipe surface of cutting ferrule 2, pipeline no longer rotates at this time, and continuing rotation cutting ferrule nut 3 makes 2 cutting edge of cutting ferrule
Firmly incision pipeline ensures to seal, by one end of fixed card buckle 4 and 3 threaded engagement of cutting ferrule nut, the other end and three-way elbow
Threaded one end connect, other both ends of three-way elbow connect with the threaded one end of fixed card buckle 4, then in the same manner,
Pipeline is threadedly coupled with the other end of fixed card buckle 4.
The utility model use bidirectional helical connector, it is easy to carry, connect and dismantle it is convenient, without using any instrument grasp
Work just can rapidly dock two systems, can be widely applied in the pipe-line systems such as hydraulic pressure, the conveying of pneumatic and lubricating fluid, in urgency
It is especially suitable in the pipeline that need to often dismount.
The above embodiment is not the limitation to the utility model, and the utility model is also not limited to the example above,
The variations, modifications, additions or substitutions that those skilled in the art are made in the range of the technical solution of the utility model,
Also the scope of protection of the utility model is belonged to.
