Further as shown in Figures 3 and 5, the front end of the first supporting part 5 is limited to and the hook extending to spray gun and the part 7 of spray gun that extends to the region being positioned at trigger front end are smooth and thickness L is less than the external diameter R of the first supporting part 5 and the second supporting part 6.By so compact design, the material of making spray gun can be saved thus make spray gun more lightweight.This part 7 of gun body 3 can be made thinner, because it need not carry any rotary part.First supporting part 5 and the second supporting part 6 should have larger width or diameter thinks that rotary part (that is, material gas flow modulation and air micrometer) provides enough spaces.
Further as described in Figure 3, the side of gun body 3 is also provided with spray configuration control handle 14, this spray configuration control handle 14 is for controlling the air distributor in gun body 3.By this air distributor, the shape that the distribution of the center air passage in gun body 3 and the air between the air duct of blast cap angle and coating thus spray can be controlled.This spray configuration control handle 14 is designed to have cylindrical shape.By so designing spray configuration control handle 14, larger rotating torque can be applied to it, and the finger of user also can not as occurring to skid from knob when stubborn taper knob.
One or more mentioned knob can have bevel edge, but they can still be regarded as cylindrical.Advantageously, knob can have anti-skid structure, such as ripple, to provide better grasping when rotating knob for user.
Again further as shown in Figure 3, gun body 3 also comprises air cap ring 15, the region being adjacent to gun body 3 of this air cap ring has identical external diameter with the region being adjacent to air cap ring 15 of gun body 3, namely, step is not formed between the end of the joint air cap ring 15 of air cap ring 15 and gun body 3, so can make the design compared to being formed with stage portion, the hand of user, gloves or oversleeve are reduced by the danger that stage portion is clamped, and the contamination build-up of junction between parts obtains less.
Further as shown in Figures 3 and 4, gun body 3 comprises the connecting portion 16 that has receiver hole 160, and this receiver hole 160 is for removably connecting paint supply portion (not shown).This connecting portion 16 has the cylindrical profile being formed with cut portion on the relative both sides of gun body 3 on the whole.Particularly, this connecting portion 16 comprise successively from receiver hole 160 side first section 161 and from first section 161 along material supplier to extend second section 162, second section 162 is designed to form depressed part 163 (cut portion) on two sides respect to one another of gun body 3, thus forms step between first section 161 and second section 162.By forming stage portion, be convenient to be gripped by user better, this is because with the connecting portion of prior art have overall constant outer diameter cylindrical compared with, first section 161 can skid off the stopper section outside the hand of user as preventing gripping spray gun spray gun comes more conversion materials supply department when user, and utilize first section 161 being used as stopper section, the support of fork type can be used to keep spray gun thus spray gun can be hung, add flexibility and the convenience of spray gun operation.
In addition, connecting portion 16 can be one-body molded with gun body 3, also can be independently parts and removably or being for good and all attached on gun body 3.
In addition, gun body is made of metal, and material flow adjustment knob, gas flow modulation knob and spray configuration control handle are made of plastics.
Alternatively, although not shown, the spray gun of the application can be coated with sub-luminescent material at least in part.Thus compared with the spray gun being coated with glossy material, when using spray gun, even if having dirt or fingerprint to be formed on spray gun, being also not easy to find out, thus avoiding spray gun to become unsightly.
Gun body 3 is coated with sub-luminescent material at least in part, and at least air cap 4, air cap ring 15, trigger, spray configuration control handle 14, gas flow modulation knob 13, material flow adjustment knob 12 and air connection piece are coated with glossy material at least in part.
Alternatively, sub-luminescent material can be sub-light chromium, and glossy material can be light chromium.
Be more than the description that the entirety of the spray gun according to embodiment of the present utility model is carried out, some function and the parts thereof of spray gun will be described particularly below.
Gas flow modulation
Fig. 6 shows the decomposition view of the second supporting part 6 according to the spray gun of embodiment of the present utility model and air micrometer 27.As shown in Figure 6, air micrometer 27 is rotatably fixed in the second supporting part 6 by screw 18, particularly, screw 18 is screwed into and is inserted in the groove 28 arranged in air micrometer 27, the end of groove 28 limits the rotation of the gas flow modulation knob 13 in air micrometer 27 thus air micrometer 27 carries out partial turn in the second supporting part 6, such as, rotate the several years.Preferably, air micrometer 27 can rotate about 80 degree to 100 degree, particularly 90 degree.
Further as shown in Figure 6, on the surface deviated from the first supporting part 5 that screw 18 is disposed in the second supporting part 6, and screw 18 is not vertically but is screwed into slightly obliquely in the second supporting part 6.The axis of screw 18 is outward-dipping relative to the side of gun body 3.By setting like this, the instrument (such as, screwdriver) that screw 18 of can avoiding being screwed into or back-outing uses collides with the handle 2 of spray gun 1, thus the scuffing avoided handle 2 and wearing and tearing.
Particularly, screw 18 is arranged in the second supporting part 6 with the angle of 70 degree to 110 degree relative to horizontal line.
Air distributes
Fig. 7 shows the isometric exploded view of distributing ring 41 according to the head 32 of the gun body of embodiment of the present utility model and air.As shown in Figure 7, the head 32 of gun body has the passage 401 and 402 of the air duct in gun body 3 and has two conjugate foramens 501 and 502.Wherein air distributes ring 41 and has two steady pins 410,411 inserted respectively in conjugate foramen 501,502, and conjugate foramen 501,502 and the air steady pin 410,411 distributed on ring 41 has corresponding shape matches to make the head 32 of gun body and air distribute both rings 41.Air distributes ring 41 and matches that with the head 32 of gun body air is assigned to center air nozzle in air cap and blast cap angle air nozzle from the passage with the air duct gun body 3.
Further, as shown in Figure 7, the distance between conjugate foramen 501 and 502 is different from the distance between passage 401 and 402.In addition, the distance between conjugate foramen 501 and passage 402 is different from the distance between two conjugate foramens 501 and 502.By such design, air can be avoided to distribute two steady pins 410 and 411 of ring 41 and to be mistakenly inserted in passage 401 and 402, thus user can be conducive to air be distributed in the head 32 that ring 41 is encased in gun body.
Alternatively, when passage and conjugate foramen all have circular cross-section as shown in Figure 7, the diameter that passage 401,402 and conjugate foramen 501,502 are designed to conjugate foramen can be greater than the diameter of passage, the diameter of the steady pin 410,411 thus in air distribution ring 41 is greater than the diameter of passage 401 and 402, thus when air being distributed in the head 32 that ring 41 is installed to gun body, steady pin 410,411 can not be inserted in passage 401 or 402, easily carries out the assembling in the head 32 of air distribution ring 41 to gun body thus.
Alternatively, can be the shape being different from passage 401 and 402 by the profile design of steady pin 410,411 and conjugate foramen 501 or 502, thus make it possible to avoid steady pin being mistakenly inserted to passage, correspondingly also facilitate user and air is distributed in the head 32 that ring is correctly assembled to gun body.Particularly, steady pin and conjugate foramen can be designed to there is rectangle, triangle or foursquare cross section, and passage be designed to there is circular cross section.In this case, the diameter that the circumscribed circle of the cross-sectional profiles of steady pin and conjugate foramen has is greater than the diameter of passage.
Although above reference Fig. 7 describes conjugate foramen and steady pin has two, but the quantity of conjugate foramen and steady pin is not limited to two, its quantity or can be able to be even one (after a while by concrete structure when description one) for two or more.And the shape of conjugate foramen and steady pin is not limited to above-mentioned description, but can be other shapes, such as other be polygon-shaped.In addition, the shape of conjugate foramen and the shape of steady pin need not to be identical, but such as conjugate foramen can have circular cross-section completely and steady pin can have circular cross-section with flat part, that is, can cut a circle segments from steady pin.By this, reduce the contact between conjugate foramen and steady pin and friction area, thus more easily can remove air distribution ring from gun body head.
Fig. 8 shows the front view distributing the variation of the decomposition view of the variation of ring and the head of gun body according to the gun body de head of the spray gun of embodiment of the present utility model and air.Note, in the following description, the identical reference symbol of use is represented and the same components shown in Fig. 7.As shown in Figure 8, the difference of the embodiment shown in the embodiment shown in Fig. 8 and Fig. 7 is, the head 32 of the gun body of this spray gun is only provided with a conjugate foramen 501, and the steady pin 410 utilizing air to distribute ring 41 inserts in this conjugate foramen 501 and air distribution ring 41 is matched with the head 32 of gun body.Owing to being only provided with a conjugate foramen, therefore in order to avoid air distributes being mistakenly inserted of the steady pin 410 of ring 41, it is the shape being different from passage 401,402 by the profile design of conjugate foramen 501, correspondingly because air distributes the cross sectional shape of steady pin 410 of ring 41 and the matching form of conjugate foramen 501 closes, thus the cross sectional shape of steady pin 410 is also different from the shape of passage 401,402.Particularly, as shown in Figure 8, exemplarily, the shape of conjugate foramen 501 and the cross sectional shape of steady pin 410 are triangle, and the shape of passage 401,402 is circular, and the diameter that the circumscribed circle of the cross-sectional profiles of steady pin 410 has is greater than the diameter of passage 401,402.
By the design of passage as above, conjugate foramen and steady pin, the steady pin 410 that ring 41 can not occur air to distribute is inserted into the situation in the passage 401,402 of the head 32 of gun body, thus easily carries out air and distribute ring and install to the cooperation in the head 32 of gun body.
Should be noted that, although the shape of the conjugate foramen 501 shown in Fig. 8 is triangle, the shape of passage 401,402 is circular, but the application is not limited to this profile design, such as, can by the profile design of conjugate foramen for having circle, rectangle, square or other polygonal cross sections, as long as the steady pin 410 that can realize matching with conjugate foramen can not be inserted in passage.Such as, when conjugate foramen and steady pin and passage all have circular cross section, steady pin can be designed to the diameter that its diameter is greater than passage.
Although, it is that the structure of the spray gun (Fig. 3 and Fig. 3) provided with the utility model is exemplarily described that the gas flow modulation of foregoing description and air distribute, but above-mentioned gas flow modulation and air distribution also can be applied to be had in the spray gun of other structures, this is those of ordinary skill in the art's easily design after reading the application, just repeats no more at this.
Below object for convenience of description, illustrates multiple improvement of the present utility model by several embodiments of minority.But, it will be appreciated by those skilled in the art that each improvement above-mentioned of the present utility model can be applied to spray gun completely independently of one another, and must all features all not combine use.
These are only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All do within spirit of the present utility model and principle any amendment, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
