Detailed Description
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.
As shown in fig. 1 and fig. 2, an embodiment of the utility model provides a fixed flange of using of air gun pigtail, including half left flange board 1 and half right flange board 2, both amalgamations of half left flange board 1 and half right flange board 2 can form the annular flange of circle together, the both ends of half left flange board 1 all are equipped with a left connecting hole 13, the both ends of half right flange board 2 all are equipped with a right connecting hole 23, and a corresponding a pair of left connecting hole 13 and right connecting hole 23 are used for articulating through detachable connections spare.
In this embodiment, the left half flange plate 1 and the right half flange plate 2 have complementary shapes and can be assembled into a circular flange, for example, both the left half flange plate 1 and the right half flange plate 2 are semi-circular structures, and both ends of the two are hinged by a detachable connecting member, so that after the detachable connecting member is detached, both the half flange plate and the right half flange plate 2 can rotate relatively around another detachable connecting member, for example, both can rotate ninety degrees. Wherein, the detachable connecting piece can be a screw or a pin. The left half flange plate 1 and the right half flange plate 2 can be of an integral structure and can be made of 316 stainless steel.
Both ends of the left half flange plate 1 are provided with left steps 12, the left connecting hole 13 is arranged on the left steps 12, namely, the two left steps 12 are respectively provided with one left connecting hole 13. The two ends of the right half flange plate 2 are both provided with right steps 22, the right connecting hole 23 is arranged on the right steps 22, namely, the two right steps 22 are respectively provided with one right connecting hole 23. When the left half flange plate 1 and the right half flange plate 2 are spliced, the two right steps 22 can be respectively positioned above the two left steps 12, so that the left connecting hole 13 and the right connecting hole 23 are overlapped.
In order to facilitate the relative rotation of the left half flange plate 1 and the right half flange plate 2 around one of the detachable connecting pieces, the end surfaces of the left step 12 and the right step 22 are arc-shaped, so that when one of the flange plates rotates, the other flange plate does not easily obstruct the rotation of the other flange plate and can rotate freely.
And the inner side surfaces of the left half flange plate 1 and the right half flange plate 2 are respectively provided with a limiting boss for limiting the pigtail 3 to move along the axial direction of the flanges. Wherein, spacing boss between them can be for the continuous circular-arc boss that extends along respective medial surface circumference, and spacing boss between them is left spacing boss 11 and right spacing boss 21 respectively, and both amalgamations of left spacing boss 11 and right spacing boss 21 form a ring form boss together. Or the limiting bosses of the two bosses can be a plurality of discontinuous arc bosses. Correspondingly, the pigtail 3 is provided with a step matched with the limit bosses of the left half flange plate 1 and the right half flange plate 2.
The flange for fixing the air gun pigtail is of a two-half structure, and the two half flange plates are hinged through a detachable connecting piece, so that a flange hole can be opened or closed. So, when dismantling air gun pigtail 3, only need dismantle the flange one detachable connections can, consuming time weak point and be convenient for dismouting. And two half flange boards adopt the design of can rotating relatively, can save the quantity of the detachable connecting piece of fixed flange board, practice thrift the cost.
As shown in fig. 3 and 4, another embodiment of the present invention provides an air gun, which includes a solenoid valve 4 and a pigtail 3 installed on the solenoid valve 4, wherein the joint of the pigtail 3 is fixed on the solenoid valve 4 by a flange according to any embodiment of the present invention.
In this embodiment, the electromagnetic valve 4 is provided with mounting holes for mounting the flanges, which are a first mounting hole 42 and a second mounting hole 41, the flanges are fixed on the electromagnetic valve 4 through a first detachable connecting piece 5 mounted in the first mounting hole 42 and a second detachable connecting piece 6 mounted in the second mounting hole 41, and the first detachable connecting piece 5 and the second detachable connecting piece 6 can both adopt screws. Be equipped with on the solenoid valve 4 and supply the round groove of joint male of pigtail 3, half left flange board 1 and half right flange board 2 are fixed on solenoid valve 4 through first releasable connecting piece 5 and second releasable connecting piece 6. Be equipped with a bulge loop on pigtail 3's the joint, pigtail 3's joint inserts in the recess, a side of its bulge loop is pressed and is seted up at solenoid valve 4 on the face of recess, another side compresses tightly through left spacing boss 11 and right spacing boss 21 on both medial surfaces of left half flange board 1 and right half flange board 2. When needs pull down pigtail 3 from solenoid valve 4, only pull down first detachable connection spare 5 or second detachable connection spare 6, then with half flange plate 1 on the left side and half flange plate 2 on the right side to both sides rotation open, can open the flange to pull down pigtail 3, it is convenient to dismantle, weak point consuming time.
The air gun of this embodiment, when dismantling air gun pigtail 3, only need dismantle a screw of flange, make two half flange boards rotatory ninety degrees can to the other end of dismantling two half flange boards in-process still is fixed in on solenoid valve 4, and the flange board is difficult for dropping. Adopt traditional flange, the dismantlement of pigtail 3 probably needs about 10 minutes with the installation, only needs now about 4 minutes just can accomplish, has shortened the dismouting time by a wide margin, and the dismouting process is easy to operate also.
