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.
