Abstract

The utility model relates to a quick connecting filling gun device, which comprises a push pipe and a valve body. The push pipe is sheathed in the valve body; the push pipe can move in the valve body; a gas inlet hole is arranged on the external end of the push pipe; concave ring grooves which are provided with two slope-shaped bottom surfaces are arranged on the external end of the push pipe; the slopes of the two ring bottom surfaces are arranged in opposite direction; two concave ring grooves are sheathed with a sealing ring; a gas outlet hole is arranged on the internal end of the push pipe; a cylindrical seat or a conical pedestal is arranged on the internal end of the push pipe; the sealing ring is sheathed on the upper end of the push pipe; a pressing spring of the cylindrical seat on the internal end of the push pipe and the valve body can form a valve, and a connecting concave ring is arranged on the valve body. When the utility model is used for filling liquefied gas, only through making use of connecting screw threads on the valve body of the filling gun or the connecting concave ring, the utility model and an empty tank body are connected together; the empty tank body can push aside the valve through the push pipe which is arranged on the filling gun body, and aeration can be started. The utility model has the advantages of convenient operation, time saving, and labor saving.

Description

Connect the filing gun device fast

The utility model relates to a kind of liquid gas and connects the filing gun device fast.

During liquid gas slack tank inflation at present, earlier that slack tank is fastening with hook, with lever operated slack tank and gas cylinder are coupled together then, it is very loaded down with trivial details to operate, and wastes time and energy, extremely inconvenient.

The purpose of this utility model is to provide a kind of filing gun easy and simple to handle that can connect and fill liquid gas slack tank bottle fast.

The purpose of this utility model is achieved in that the utility model comprises push pipe and valve body, push pipe is sleeved in the valve body, push pipe can move in valve body, the outer end of push pipe is provided with inlet hole, it is the slope shape concave ring groove that the outer end of push pipe is provided with two bottom surfaces, the slope of two ring bottom surfaces is the opposite direction setting, be set with seal ring on two concave ring grooves, the inner of push pipe is provided with air outlet hole, the inner of push pipe is cylindrical seat or circular cone pedestal, its upper end is set with seal ring, cylindrical seat of push pipe the inner and stage clip, valve body constitutes valve, and valve body is provided with the connection scrobicular ring.

The utility model circular cone pedestal and push pipe adopt and are threaded.

Use the utility model can liquid gas, only need utilize the connecting thread on the filing gun valve body or connect scrobicular ring the utility model and slack tank bottle are linked together, the valve open that the slack tank body will be made of cylindrical seat, stage clip and valve body by the push pipe that is arranged on the filing gun body, promptly begin inflation, easy and simple to handle and time saving and energy saving.

Accompanying drawing 1 is the utility model structural representation.

Accompanying drawing 2 is the utility model closed state schematic representation.

Accompanying drawing 3 is the utility model schematic representation that is connected with the tank body connecting head.

Accompanying drawing 4 is the utility model push pipe schematic representation.

In the accompanying drawings: stage clip, 16 inner ring sleeves, 17 locking steelballs, 18 boss, 19 outer stage clips, 20 outer ring sets, 21 headings, 22 stage clips, 23 valve bodies, 24 concave ring grooves, 25 slopes in 1 push pipe, 2 concave ring grooves, 3 filing gun valve bodies, 4 scrobicular rings, 5 air outlet holes, 6 seal rings, 7 slopes, 8 stage clips, 9 inlet holes, 10 seal rings, 11 seal rings, 12 cylindrical seats, 13 collars, 14 connecting heads, 15.

Below in conjunction with accompanying drawing the utility model is described in detail:

Shown in accompanying drawing 1,2,4, the utility model filing gun valve body 3 is provided with and connects scrobicular ring 4, when the utility model is inserted connecting head 14, push pipe 1 inwardly pushes inner ring sleeve 16, the interior stage clip 15 of connecting head 14, locking steelball 17 promotion of the boss 18 on stage clip 19, the outer ring set 20 outside falls in the connection scrobicular ring 4 on the valve body 3, finishes connection procedure.The filing gun body when connecting head 14 is pulled down, is only needed to the moving outer ring set 20 of connecting head 14 1 thrusters, and locking steelball 17 from being connected release in the scrobicular ring 4, is released the filing gun body under the effect of inner ring sleeve 16 and interior stage clip 15 simultaneously from connecting head 14.Push pipe 1 the inner is a cylindrical seat 12.

As accompanying drawing 1,2, shown in 3, the utility model is provided with one by heading 21 in connecting head 14, the goal valve that stage clip 22 and valve body 23 constitute, the push pipe 1 of filing gun body inserted connecting head 14 and with after connecting head 14 is connected, the goal valve that push pipe 1 on the filing gun body also will be arranged in the connecting head 14 simultaneously backs down, push pipe 1 inwardly promotes stage clip 8 by cylindrical seat 12 simultaneously, open the filing gun valve, gas in the steel cylinder is finished gas replenishment process by inlet hole on the push pipe 19 and air outlet hole 5, as shown in Figure 3, in gas replenishment process, be sleeved on the seal ring 10 on the push pipe 1,11 seal valve body 23 and filing gun valve body 3 respectively, guarantee in gas replenishment process air tight.

Make two seal rings 10,11 slope 25,7 motions to the inside simultaneously at valve body 3 with the frictional force by two seal rings 10,11 on the push pipe 1 and filing gun valve body 3, valve body 23 inner hole walls when the rifle body is connected, lean on the tension of seal ring 10,11 and the Driving force of push pipe 1 two ends gas that rifle body and valve body 3 are tightly connected.Because push pipe 1 terminal the employing is threaded, and makes assembling more convenient.
