Description
Technical field
The present invention relates to spray gun, in particular to the spraying swath fast adjuster of a kind of spray gun.
Background technique
Spray gun is the tool for spray painting.Spray gun rear end is connected with compressed gas, and the spray of storage spray painting is equipped on spray gun
Pot.When spray gun works, spray painting is taken out of from spray gun pipette tips by compressed gas and is atomized spray painting, to reach even application
Effect.
The patent of the Patent No. 201310352976.0 of my company's application discloses one kind and is provided with amplitude step-less adjustment
The spray gun and its amplitude stepless regulator of device.The spray gun can be quickly to the injection of spray gun by amplitude stepless regulator
Amplitude is adjusted, and the spray painting shape sprayed is made to become ellipse from circle.
But there are the following problems for this kind of structure:
1, as shown in Figure 10 in this patent, adjusting spinner handle overall structure is complex, and primary air groove and secondary streams groove are equal
To fan annular groove, need to be processed by milling cutter, process velocity is slower, and processing is more difficult, and production cost is higher.
2, since amplitude hole is blind hole, processing difficulties, blind hole bottom edge flatness and machining accuracy are poor, in order to avoid
Regulating valve stem right end edge contacts with blind hole bottom edge and causes clamping stagnation, and regulating valve stem right end end is cambered surface.This causes to adjust
Contact length between valve rod right end end and amplitude hole becomes smaller, and positioning and guiding effect is deteriorated, and leads to regulating valve stem right end end
It is easy to happen swing, influences the sealing performance between regulating valve stem and amplitude hole.
3, in order to guarantee the concentricity between regulating valve stem and amplitude hole, regulating valve stem right end end is provided with steel bead groove simultaneously
Steel ball is installed, so that regulating valve stem and spray gun overall structure are more complicated, processing, assembly difficulty.
4, it is not provided with circumferential limiting device on regulating valve stem, so that the slewing area of regulating valve stem is unrestricted, adjusts
It is inconvenient.
Summary of the invention
In view of the deficiencies of the prior art, the present invention intends to provide a kind of spraying swath of spray gun quickly to adjust dress
It sets, structure is simple, adjusts, easy to process, good seal performance.
Above-mentioned technical purpose of the invention has the technical scheme that a kind of fast velocity modulation of the spraying swath of spray gun

Through the above technical solutions, air slot is arranged on regulating valve stem relative to being arranged in adjustment hole, processing is more
Convenient, production cost is lower.
Preferably, regulating valve stem both ends are provided with seal groove, are equipped with sealing ring in seal groove.
Through the above technical solutions, the setting of sealing ring can be to avoid compressed gas between regulating valve stem and control hole
Gap leaks out, and causes the waste of compressed gas.
Preferably, adjustment hole is through-hole.
Through the above technical solutions, adjustment hole is through-hole, drill bit or milling cutter are completely through gun body when processing, so that control
The machining accuracy and surface accuracy in hole can preferably be guaranteed that the processing for being not likely to produce similar blind hole bottom edge lacks
It falls into.
Preferably, regulating valve stem one end is provided with flange, and adjustment hole one end is provided with limiting slot, and flange is in limiting slot
It is interior.
Through the above technical solutions, the setting of flange can limit the axial position of regulating valve stem, facilitate adjusting
The fixation of valve rod.
Preferably, it is arranged jagged on flange, is provided with double wedge on limiting slot, double wedge is caught in notch limitation regulating valve stem
Rotational angle.
Through the above technical solutions, the setting of notch and double wedge can limit the rotational angle of regulating valve stem, make
It must adjust more convenient, accurate, efficient.
Preferably, the regulating valve stem other end is equipped with knob, and knob end and gun body contradict.
Preferably, on the one hand the setting of knob is convenient for rotating regulating valve stem, on the other hand can consolidate to regulating valve stem
It is fixed, avoid regulating valve stem from deviating from from limiting slot side.
Compared with prior art, the invention has the benefit that carrying out weight by the structure to regulating valve stem and adjustment hole
New design processes more convenient, the concentricity between regulating valve stem and adjustment hole so that regulating valve stem overall structure is simpler
It can preferably be guaranteed, reduce swing of the regulating valve stem in adjustment hole, obtain better seal effect.Turned by circumferential
Dynamic regulating valve stem and then lance ejection amplitude is adjusted, only need to rotate lesser angle i.e. and can control gas outlet two from standard-sized sheet to complete
It closes, adjusts more convenient.
