Abstract
An air-intake device of a paint spray gun comprises an air-intake rod, a flat gasket, a spring, a seal ring, an air-intake adjusting screw and an air-intake retaining screw; the air-intake adjusting screw and the air-intake retaining screw are connected with an air-intake rod through threads; the flat gasket and the rubber ring are arranged on the air-intake retaining screw; the spring is mounted on the air-intake rod; and the air-intake device is characterized in that a lug boss is further included and is arranged on the air-intake rod, one end of the spring is propped against the lug boss, and the other end of the spring is propped against the flat gasket. The utility model aims to provide the air-intake device with simple structure, low possibility of breakage of the air-intake rod, convenience in assembly and low failure rate for the paint spray gun.
Description
Technical field
The utility model relates to a kind of inlet duct of spray gun for paint.
Background technology
In spray gun for paint,, all can be provided with inlet duct by the rifle body, to regulate the size of air inflow for control enters the compressed-air actuated tolerance of spray gun for paint.The inlet duct of existing spray gun for paint comprises air intake lever 1, jump ring 2, spring 3, plain cushion 4, rubber ring 5, air inlet hold-down screw 6, air intake adjusting screw 7 as shown in Figure 1; Air inlet hold-down screw 6, air intake adjusting screw 7 connect with air intake lever 1 by screw thread, air intake lever 1 is provided with jump ring 2, air inlet hold-down screw 6 is provided with plain cushion 4, rubber ring 5, spring 3 is installed on the air intake lever 1, and spring 3 one ends withstand on the jump ring 2, and the other end withstands on the plain cushion 4.Under the effect of spring 3, plain cushion 4 extruding rubber rings 5 make and form sealing between air intake adjusting screw 7 and the air intake lever 1.
In the use, rotation air inlet hold-down screw 6, and then produce and move axially, air intake lever 1 is produced move forward and backward, thereby realize the air inflow size adjustment.Because of rifle body space constraint, air intake lever 1 itself is very thin, adds and cut jump ring 2 on bar, causes that air intake lever 1 is as easy as rolling off a log to fracture at jump ring 2 places or crooked, and jump ring is very little, and assembling is inconvenient, and the fault rate during use is also high.
The utility model content
The utility model aims to provide not frangibility of a kind of simple in structure, air intake lever, the spray gun for paint inlet duct that equipment is convenient, fault rate is low.
The technical scheme that the utility model adopted is: a kind of inlet duct of spray gun for paint comprises air intake lever, plain cushion, spring, sealing ring, air intake adjusting screw, air inlet hold-down screw; Air intake adjusting screw, air inlet hold-down screw connect with air intake lever by screw thread, and the air inlet hold-down screw is provided with plain cushion, rubber ring, and spring is installed on the air intake lever, it is characterized in that also comprise boss, described boss is arranged on the air intake lever, spring one end withstands on the boss, and the other end withstands on the plain cushion.
The beneficial effects of the utility model are: the jump ring in the original structure is improved to boss, and simple in structure, processing and manufacturing is easy.Both overcome that the existing structure air intake lever fractures easily or crooked shortcoming, and assembling is also simpler, is difficult for during use breaking down.
Description of drawings
Accompanying drawing 1 is the existing structure schematic diagram of the inlet duct of a kind of spray gun for paint of the utility model;
Accompanying drawing 2 is improvement structural representations of the inlet duct of a kind of spray gun for paint of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in detail:
Embodiment of the present utility model shown in attached 2 figure, a kind of inlet duct of spray gun for paint, air intake lever 1, boss 2, spring 3, plain cushion 4, rubber ring 5, air inlet hold-down screw 6, air intake adjusting screw 7; Air inlet hold-down screw 6, air intake adjusting screw 7 connect with air intake lever 1 by screw thread, air intake lever 1 is provided with boss 2, air inlet hold-down screw 6 is provided with plain cushion 4, rubber ring 5, spring 3 is installed on the air intake lever 1, and spring 3 one ends withstand on the boss 2, and the other end withstands on the plain cushion 4.Under the effect of spring 3, plain cushion 4 extruding rubber rings 5 make and form sealing between air intake adjusting screw 7 and the air intake lever 1.
In actual use, because the jump ring in the original structure is improved to boss 2, simple in structure, processing and manufacturing is easy.Both overcome that existing structure air intake lever 1 fractures easily or crooked shortcoming, and assembling is also simpler, is difficult for during use breaking down.
