The utility model relates to combustion gas aerating technical field, and particularly a kind of combustion gas connects air filling gun soon.
Existing a kind of combustion gas connects air filling gun soon, comprise the rifle body portion, eccentric shaft is contained on the switch base, end cap is equipped with on its top, limited ring, pin, shift bar and seal washer, the eccentric shaft bottom is connected with stud bolt one head thread by connecting ring, the stud bolt other end is threaded with plunger back-end, the plunger front end is fastened with rubber cushion, described switch base rear end thread seal is connected with joint, also include the quick-acting joint part, the front portion of answering back of band center roof vent is threaded with connecting sleeve, and seal by sealing gasket, the connecting sleeve front threads is connected with fittings body, is provided with the interior top cover and the interior sleeve spring that can relatively move on the fittings body inner tube surface, and the outer unlatching cover and the outer casing spring that can move along its outer surface is housed at the fittings body outer surface, on fittings body, also be provided with steel ball and Steel Cable Baffle Ring, be connected with the lock pin of band center roof vent in connecting sleeve front end central, threaded, this lock pin front end sidepiece is provided with a plurality of air outlet holes, and the lock pin middle front part is parallel to be equipped with three O-ring seals; Described switch base is anterior to be connected with the O-ring seals thread seal by joint with the rear portion of answering back.Because lock pin needs the frequent cylinder joint inflation of inserting, its three O-ring seals wear and tear easily; Need change these seal rings frequently, thereby reduce its working life, operation is safety, quick inadequately.
The purpose of this utility model is to provide a kind of easy to operate, quick, safe, durable combustion gas to connect air filling gun soon, and it not only can be applicable to conventional cylinder joint inflation, also can be applicable to novel steel cylinder quick-acting joint inflation.
The purpose of this utility model is achieved in that a kind of combustion gas connects air filling gun soon, comprise the rifle body portion, eccentric shaft (11) is contained on the switch base (7), end cap (5) is equipped with on its top, limited ring (3), pin (4), shift bar (2) and seal washer, eccentric shaft (11) bottom is connected with a head thread of stud bolt (12) by connecting ring (9), stud bolt (12) other end is threaded with plunger (16), plunger (16) front end is fastened with rubber cushion (18), described switch base (7) rear end thread seal is connected with joint (10), also include the quick-acting joint part, answer back (17) of band center roof vent are anterior to be threaded with connecting sleeve (19), and seal by sealing gasket (20), connecting sleeve (19) front threads is connected with fittings body (27), on fittings body (27) inner tube surface, be provided with the interior top that can relatively move and overlap (25) and interior sleeve spring (24), the outer unlatching cover (22) and the outer casing spring (21) that can move along its outer surface is housed at fittings body (27) outer surface, on fittings body (27), also be provided with steel ball (23) and snap ring (26), described switch base (7) is anterior to pass through joint (14) and O-ring seals (13 with (17) rear portion of answering back, 15) thread seal connects, described connecting sleeve (19) first half is provided with the lock pin (30) of the band center roof vent that is complementary with cylinder joint, and described lock pin (30) front end sidepiece is provided with a plurality of air outlet holes.
Advantage of the present utility model is that the cylinder joint that can be applicable to the plurality of specifications pattern uses, and convenient to operation, owing to cancelled three O-ring seals of lock pin middle front part, and it is retrofitted on the cylinder joint body, so prolonged its working life greatly, and reduced labor intensity.
Fig. 1 is the structural representation that a kind of combustion gas of the utility model connects air filling gun soon.
Referring to shown in Figure 1, embodiment's combustion gas of the utility model connects air filling gun soon partly to be made up of rifle body portion and quick-acting joint, and the composition and the linkage structure of each several part are as follows:
Eccentric shaft 11 is housed on the switch base 7, and dual O-ring seals 6 is housed in its cooperation place, on eccentric shaft 11, be inserted in end cap 5 and limited ring 3, end cap 5 is fastened on the eccentric shaft 11 by screw 29, between end cap 5 and the limited ring 3 pin 4 is housed, eccentric shaft 11 tops are fixed with shift bar 2 by screw 1, are provided with O-ring seals 28 between end cap 5 and the switch base 7.Switch base 7 rear ends are connected with joint 10 by O-ring seals 8 thread seals.Eccentric shaft 11 bottoms are connected with a head thread of stud bolt 12 by connecting ring 9, and these stud bolt 12 other ends are connected with plunger 16 threaded one ends, and plunger 16 the other ends are fastened with rubber cushion 18 by screw.The above-mentioned rifle body portion of having formed.Switch base 7 front portions are connected with O-ring seals 13,15 thread seals by joint 14 with 17 rear portions of answering back.Be the quick-acting joint part below, 17 front portions of answering back of band center roof vent are threaded with connecting sleeve 19, and by sealing gasket 20 sealings, connecting sleeve 19 front threads are connected with fittings body 27, at fittings body 27 outer surfaces the outer unlatching cover 22 and the outer casing spring 21 that can move along its outer surface is housed, also is provided with steel ball 23 and snap ring 26 interior top cover 25, interior sleeve spring 24, the outer unlatching on the fittings body 27 that overlaps between 22.At connecting sleeve 19 anterior lock pins 30 for the band center roof vent, these lock pin 30 front end sidepieces are provided with a plurality of air outlet holes.
