After a number of uses, sealing effect can reduce rubber seal, if replacing not in time, can reduce sealing effect.Further, since
Coating in spraying equipment has stronger corrosivity, and after long-time service, coating can also corrode rubber seal, so as to reduce sealing
Effect influences the service life of equipment.
Utility model content
The technical problem to be solved by the utility model is to overcome the deficiency of the above-mentioned prior art, a kind of leakproofness is provided
Good, service life length the sealing structure being used in spraying equipment.
Connect according to a kind of sealing structure in spraying equipment provided by the utility model, first including metal material
Second connector of fitting and metal material, first connector and the second connector are linked together by screw element, institute
It states and external seal binding face is formed on the first connector, interior sealing binding face, the external seal patch are formed on the second connector
Together with conjunction face is fitted closely with the interior sealing binding face under the action of screw thread pulling force.
Also there is following attached technology spy according to a kind of sealing structure in spraying equipment provided by the utility model
Sign：
Further comprise, tapered portion is formed on first connector, and the external seal binding face forms in the cone
In shape portion.
Further comprise, loudspeaker oral area is formed on second connector, and the interior sealing binding face forms in described
On loudspeaker oral area.
Further comprise, external screw thread be formed on first connector, internal thread is formed on second connector,
The external screw thread and the internal thread mesh together.
Further comprise, external screw thread be formed on first connector, a nut is connected on second connector,
The nut is engaged with the external screw thread.
Further comprise, it is at least one using soft metal material in first connector and second connector
It is made.
Have compared with prior art such as according to a kind of sealing structure in spraying equipment provided by the utility model
Lower advantage：The utility model sets palette face on two metal connecting pieces, is drawn by two metal-clad faces in screw thread
It fits closely to realize sealing under power effect, the meeting of this metal-clad face is with the increase of number of use, what is be bonded is increasingly tighter
Close, sealing effect is become better and better, and will not reduce sealing effect with the increase of access times.Also, this metal directly pastes
Closing structure will not be corroded be subject to coating, and service life is longer.
Description of the drawings
Fig. 1 is the three-dimensional exploded view of the utility model；
Fig. 2 is the sectional view of the utility model.
Fig. 3 is the sectional view of the utility model another kind embodiment.
Fig. 4 is enlarged drawing at A in Fig. 3.
Specific embodiment
Clearly to illustrate the scheme in the utility model, be given below preferred embodiment and with reference to attached drawing specifically
It is bright.Application that is that the following description is substantially merely exemplary and being not intended to the limitation disclosure or purposes.It should be understood that
, in whole attached drawings, corresponding reference numeral represents identical or corresponding component and feature.
As depicted in figs. 1 and 2, a kind of sealing structure in spraying equipment provided by the utility model, including metal
First connector 1 of material and the second connector 2 of metal material, 1 and second connector 2 of the first connector pass through screw thread
Part links together, and external seal binding face 11 is formed on first connector 1, is formed on second connector 2 interior
Palette face 21, the external seal binding face 11 and the interior sealing binding face 21 fit closely under the action of screw thread pulling force
Together.The spraying equipment of the utility model refers to the equipment for ejecting material by gases at high pressure, includes but not limited to
The spraying equipments such as spray gun.In the present embodiment, 1 and second connector 2 of the first connector refers to connector and bend pipe, connector respectively
It links together with bend pipe needs, and the two needs to be tightly connected.The utility model passes through external seal binding face 11 and interior sealing
Binding face 21 fits closely realization sealing, since two binding faces are all metal materials, with the increase of number of use, two gold
Belonging to binding face can rub more and more smooth, and compactness is higher and higher, and therefore, the effect of sealing can become better and better.It is also, this
Metal-clad face is not afraid of is corroded be subject to chemical composition in coating, and service life is longer.
Referring to Fig. 1 and Fig. 2, in the above-described embodiment provided in the utility model, further comprise, first connector
Tapered portion 12 is formed on 1, the external seal binding face 11 is formed in the tapered portion 12.On second connector 2 into
Shape has loudspeaker oral area 22, and the interior sealing binding face 21 is formed on the loudspeaker oral area 22.The loudspeaker oral area 22 is fastened on
In tapered portion 12, the external seal binding face 11 and interior sealing binding face 21 are ramp structure, with the increase of screw thread pulling force,
What can be bonded is increasingly closer, improves sealing effect.
Referring to Fig. 1 and Fig. 2, in the above-described embodiment provided in the utility model, further comprise, first connector
External screw thread 13 is formed on 1, a nut 23 is connected on second connector 2, the nut 23 is nibbled with the external screw thread 13
It closes.The internal diameter of nut 23 in the present embodiment is less than the oral area of second connector 2, so as to haul second connection
Interior sealing binding face 21 on part 2 is close to the external seal binding face on the first connector 1.
