Description
Technical field
The utility model relates to spraying equipment, more particularly, and particularly a kind of spray gun.
Background technology
Existing pneumatic spray gun is all generally produce vacuum by high-pressure air pipe, thus by suction tube, the coating in storage vat is drawn to shower nozzle place, then mix with the gases at high pressure in high-pressure air pipe, finally spray from shower nozzle, complete the spray coating operations of pneumatic spray gun.In existing spray gun, the general threaded connection hole that convenient installation storage vat all can be set on gun body, and suction tube is arranged in threaded connection hole, suction tube extends in storage vat from threaded connection hole, suction tube can be facilitated like this in storage vat to draw coating, but people are when disassembling storage vat from gun body, after just needing storage vat to screw out in threaded connection hole, slide downward again, suction tube is stretched out in storage vat, finally can people can to take freely storage vat, thus the reinforced work completed storage vat.
Like this when suction tube extracts by people in storage vat, often easily mode is collided, thus along bad fragile suction tube, suction tube is made to produce bending or distortion, suction tube is made to block or reach bottom storage vat, suction tube can not be drawn or a small amount of coating can only be drawn, affect the spraying effect of pneumatic spray gun or even make pneumatic spray gun ineffective; And after suction tube bends, suction tube just reaches at the bottom of storage vat bucket, coating can be produced in storage vat residual, shine into serious waste.

In order to achieve the above object, the technical solution adopted in the utility model is as follows: a kind of spray gun, the storage vat comprising the handled gun body of band and be detachably connected on gun body, described gun body is provided with joint pin, described joint pin is threaded connection hole and is threaded with storage vat, be provided with suction tube in described threaded connection hole, described suction tube comprises suction tube body and can control the telescope support in suction tube body retraction threaded connection hole.
Preferably, described suction tube body comprises the fixed bar and telescopic sleeving rod fixing and be vertically arranged in threaded connection hole, and described telescopic sleeving rod is set on fixed bar; Described telescope support comprises expansion link with engaging tooth and linkage gear; Described expansion link slippage is arranged in threaded connection hole, and described expansion link one end can be inconsistent with storage vat; Described telescopic sleeving rod sidewall is provided with interlock teeth groove, and described linkage gear is arranged between expansion link and telescopic sleeving rod, and is meshed with engaging tooth and linkage gear simultaneously.
Preferably, comprise some expansion links, described each expansion link can be provided with conflict ring with central through hole in the inconsistent one end of storage vat, and the described axis of conflict ring overlaps mutually with the axis of threaded connection hole.
Preferably, described fixed bar is arranged with thrust spring, described thrust spring one end is fixedly connected with the hole end surface that is threaded, and the thrust spring other end is fixedly connected with expansion link.
Compared with prior art; the beneficial effects of the utility model are: people are when disassembling storage vat from joint pin; its telescope support will control in suction tube body retraction threaded connection hole; thus suction pipe can be made to stretch out in storage vat gradually; make people when storage vat is taken off supplementary coating operations from pedestal; can not suction tube be damaged to, better defencive function can be played to suction tube, improve the service life of spray gun.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, the utility model gun embodiment is described further.
A kind of spray gun, the storage vat 2 comprising the handled gun body 1 of band and be detachably connected on gun body 1, described gun body 1 is provided with joint pin 3, described joint pin 3 is threaded connection hole 31 and is threaded with storage vat 2, be provided with suction tube 4 in described threaded connection hole 31, described suction tube 4 comprises suction tube body 42 and can control the telescope support 41 that suction tube body 42 retracts in threaded connection hole 31.People are when screwing out storage vat 2 gradually from the threaded connection hole 31 joint pin 3; its telescope support 41 will control suction tube body 42 and retract in threaded connection hole 31; thus suction pipe can be made to stretch out in storage vat 2 gradually; make people when storage vat 2 is taken off supplementary coating operations from pedestal; suction tube 4 can not be damaged to; better defencive function can be played to suction tube 4, improve the service life of spray gun.
Described suction tube body 42 comprises the fixed bar 421 and telescopic sleeving rod 422 fixing and be vertically arranged in threaded connection hole 31, and described telescopic sleeving rod 422 is set on fixed bar 421; Described telescope support 41 comprises expansion link 411 with engaging tooth 4111 and linkage gear 412; The slippage of described expansion link 411 is arranged in threaded connection hole 31, and described expansion link 411 one end can be inconsistent with storage vat 2; Described telescopic sleeving rod 422 sidewall is provided with interlock teeth groove 4221, and described linkage gear 412 is arranged between expansion link 411 and telescopic sleeving rod 422, and is meshed with engaging tooth 4111 and linkage gear 412 simultaneously.People are when controlling storage vat 2 and screwing out in the threaded connection hole 31 joint pin 3 gradually, expansion link 411 can be inconsistent with storage vat 2 all the time, people are when exiting storage vat 2 in threaded connection hole 31, expansion link 411 also can from inconsistent with storage vat 2, thus expansion link 411 can be stretched out gradually in threaded connection hole 31, and the engaging tooth 4111 on expansion link 411 just can drive linkage gear 412 to rotate, linkage gear 412 is allowed to be rotated in threaded connection hole 31, most relief linkage gear 412 drives telescopic sleeving rod 422 slippage on fixed bar 421, gradually in retraction threaded connection hole 31.This makes it possible to make that people can be convenient by storage vat 2 taking off from joint pin 3 safely and fast, can protect suction tube 4 with more effective.
Comprise some expansion links 411, described each expansion link 411 can be provided with conflict ring 43 with central through hole in the inconsistent one end of storage vat 2, and the axis of described conflict ring 43 overlaps mutually with the axis of threaded connection hole 31.Its expansion link 411 is provided with 4, and expansion link 411 can be all connected and fixed by conflict ring 43 the inconsistent one end of storage vat 2, the control work to expansion link 411 more rapidly and efficiently can be completed like this by the effect of conflict ring 43, and 4 expansion links 411 can also be made can to realize being synchronized with the movement, this makes it possible to make more steady safe the returning in threaded connection hole 31 along fixed bar 421 slippage of telescopic sleeving rod 422.
Described fixed bar 421 is arranged with thrust spring 5, and described thrust spring 5 one end is fixedly connected with threaded connection hole 31 end face, and thrust spring 5 other end is fixedly connected with expansion link 411.Can make expansion link 411 can eject fast away from one end of thrust spring 5 in threaded connection hole 31 by the effect of thrust spring 5, thus telescopic sleeving rod 422 can be allowed to retract in threaded connection hole 31 along fixed bar 421 fast.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
