According to the paint spraying gun, the structure is simple, the design is ingenious, and in the large-batch industrial production, the work efficiency can be improved greatly, and the production cost can be lowered effectively.

Description

A kind of spray gun for paint that sprays paint continuously

Technical field

The utility model belongs to the paint application instrument, belongs to spray gun for paint specifically.

Background technology

The pot type spray gun for paint is the current paint spraying outfit that generally uses, and comprises rifle body, trigger, is contained in storage paint can on the rifle body, is located at the air inlet of rifle body rear end.Air inlet connects air pump through air inlet pipe, charge of oil lacquer in the storage paint can, and cocking can carry out paint spraying.Along with the requirement of mass industrialized production, existing pot type spray gun for paint exists following not enough: 1) can not face upward and spray paint; Need clean tank body again when 2) needing frequent filling lacquer and replacing color; Be easy to pollute and waste when 3) irritating lacquer; 4) spray gun for paint is heavy, hand-held effort.More than some show when working long hours in the large tracts of land operation particularly evident, greatly limited operating efficiency, increased production cost.

The utility model content

The technical problem that the utility model will solve provides a kind of quick change soon lacquer, exempts to clean, easily hand-held, arbitrarily angled spraying and the convenient long-time spray gun for paint that sprays paint continuously that uses.

For solving the problems of the technologies described above, the utility model comprises into Qi Kou, and its design feature is saidly to advance on the lacquer mouthful multichannel to be installed and to change the lacquer valve, and multichannel is changed the lacquer valve and had the arm that is communicated with its minute appraise and select one.

Said multichannel is changed the person in charge that the lacquer valve comprises and advance lacquer mouthful connection, is responsible for the lower end and is arranged with the arm more than two, and each arm is provided with valve.

Said multichannel is changed the lacquer valve and is comprised and advance a lacquer mouthful person in charge who is communicated with, be responsible for the lower end and be arranged with the arm more than two, each arm be responsible for intersection and be provided with the switching-over knob, be responsible for through the switching-over knob and select one be communicated with arbitrary arm.

Said arm arrives the storage paint can through soft pipe connection.

Compared with prior art, the beneficial effect of the utility model is: change the lacquer valve through multichannel and can realize fast quick change lacquer, reduced a lot of troubles; Multichannel is changed the lacquer valve and has been substituted former storage paint can and can realize arbitrarily angled spraying, and whole spray gun for paint weight saving, and labour intensity reduces; The storage paint can pour into paint at any time and not influence continuous spray painting operation.The utility model is simple in structure, and deft design can be increased work efficiency in mass industrialized production greatly, effectively reduces production costs.

Description of drawings

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further explain:

Fig. 1 is a pot type spray gun for paint sketch map in the background technology;

Fig. 2 is the utility model sketch map;

Fig. 3 changes lacquer valve sketch map for the multichannel of first kind of embodiment of the utility model;

Fig. 4 changes lacquer valve sketch map for the multichannel of second kind of embodiment of the utility model.

The specific embodiment

Fig. 1 is the pot type spray gun for paint in the background technology, comprises rifle body 1, and rifle body 1 is provided with trigger 4; Rifle body 1 preceding bottom is provided with into lacquer mouth 3, advances storage paint can 5 is housed on the lacquer mouth 3, and rifle body 1 rear end is provided with air inlet 2; Air inlet 2 is received on the air pump through air inlet pipe 6; Load onto paint in the storage paint can 5 during use, open air pump, cocking 4 carries out spraying operation.

The utility model shown in Figure 2 comprises rifle body 1, be located at trigger 4 on the rifle body 1, advance lacquer mouthfuls 3, air inlet 2, advances on the lacquer mouthfuls 3 multichannel to be installed and to change the lacquer valve, and multichannel is changed the lacquer valve and had the arm 8 that is communicated with its minute appraise and select one.Arm 8 is communicated to storage paint can 11 through flexible pipe 10.Air inlet 2 is received on the air pump through air inlet pipe 6, and air pump adopts general mini air compressor to get final product.The height of storage paint can 11 is higher than whole spray gun for paint, and both form a difference in height, and paint is because difference in height flows to spray gun for paint, can control what of amount of paint of conveying through the height of regulating storage paint can 11.Wherein the length of flexible pipe 10 and air inlet pipe 6 is according to concrete boundary of works area decision; And thick rare degree according to paint; Generally speaking; The length of flexible pipe 10 is that 5:1 is more suitable with storage paint can 11 apart from the ratio of the difference in height of spray gun for paint, if i.e.: flexible pipe 10 long five meters, the suspension height that stores up paint can 11 so during with construction the difference in height of spray gun for paint be one meter proper.

Fig. 3 shows a kind of multichannel and changes the lacquer valve, comprises and advance the person in charge 7 of lacquer mouthful 3 connections, is responsible for 7 lower ends and is provided with two-way arm 8, and each arm 8 is provided with valve 9.Be responsible for 7 upper ends and be provided with and advance the external screw thread 17 that lacquer mouthful 3 internal threads adapt, be responsible for 7 spiral shells and be contained in the air inlet 3.Two to four of arm 8 operated by rotary motion are provided with the break-make that a valve 9 is controlled these arms 8 respectively on each arm 8.Be socketed with flexible pipe 10 on the arm 8, flexible pipe 10 other ends are received in the outlet of storage paint can 11.

Fig. 4 shows another kind of multichannel and changes the lacquer valve, comprises and advances the person in charge 7 that lacquer mouthfuls 3 is communicated with, be responsible for 7 lower ends and be arranged with two-way arm 8, each arm 8 be responsible for 7 intersections and be provided with switching-over knob 14, be responsible for 7 and select one be communicated with arbitrary arm 8 through switching-over knob 14.Be responsible for 7 upper ends and be provided with and advance the external screw thread 17 that lacquer mouthful 3 internal threads adapt, be responsible for 7 spiral shells and be contained in the air inlet 3.Switching-over knob 14 comprises inner spool 13 and outer knob 12, inner spool 13 stretch out be responsible for 7 inner chambers and outer knob 12 affixed.Inner spool 13 corresponding one road arms 8 have an inclined-plane breach 15, and this inclined-plane breach 15 is communicated with one road arm, 8 inner chambers and the person in charge's 7 inner chambers, and other does not have breach 15 corresponding arm 8 inner chambers in inclined-plane to be sealed by inner spool 13.Rotate outer knob 12 and drive inclined-plane breach 15 rotations on the inner spool 13, inclined-plane breach 15 correspondence again is communicated with another road arm 8 inner chambers and is responsible for 7 inner chambers, thereby realizes that the person in charge 7 selects one and is communicated with arbitrary arm 8.Two to four of arm 8 operated by rotary motion.Be socketed with flexible pipe 10 on the arm 8, flexible pipe 10 other ends are received in the outlet of storage paint can 11.

When the utility model specifically uses; Versicolor storage paint can 11 height will be housed be hung on the job site, connect the outlet of storage paint can 11 and each arm 8 that multichannel is changed the lacquer valve, connect air inlet 2 and air pump with air inlet pipe 6 with flexible pipe 10; Flexible pipe 10 can band together with air inlet pipe 6; Open air pump, regulate multichannel and change the color that the selection of lacquer valve will be used, cocking 4 can carry out spraying operation.When changing lacquer, change the lacquer valve through multichannel and select to be communicated with another color paint, cocking 4, the paint that use the front in the rifle after several seconds can rinse, and carries out next step operation then.
