In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of automatic telescopic nozzle, comprise the nozzle carrier of hollow tube-shape and to be nested in nozzle carrier and the telescopic piston moved along its axis, described nozzle carrier one end is as compressed-air actuated entrance, other end madial wall is provided with the first annular protrusion, the internal diameter of this first annular protrusion is equal with telescopic piston external diameter, described telescopic piston is hollow cylinder, its one end lateral wall in nozzle carrier is provided with the second annular protrusion, the external diameter of this second annular protrusion is equal with the internal diameter of nozzle carrier, the other end of described telescopic piston is connected with calibrating nozzle, back-moving spring is provided with in described telescopic piston, one end of this back-moving spring is connected with nozzle carrier, its other end is connected with telescopic piston, when connecting to make source of the gas, telescopic piston is under stream pressure active force, overcome back-moving spring resistance, drive calibrating nozzle auto-extending to operating position, when source of the gas disconnects, under the active force of back-moving spring, telescopic piston is retracted in nozzle carrier.
Further, the end face of described second annular protrusion, as air-flow stress surface, promotes telescopic piston and moves.
Further, the sidewall of described nozzle carrier is provided with the check valve being communicated with its inner space, this check valve arranges on the sidewall between the first annular protrusion and the second annular protrusion, and this check valve is closed when ventilating, and opens and be in communication with the outside when dying.
Further, in described nozzle carrier and telescopic piston all in be provided with bracket for allowing back-moving spring catch on, this bracket comprises the stud of a hollow, is provided with cross bar in stud, this stud is threadedly connected to nozzle carrier and telescopic piston respectively, and cross bar is caught on respectively in the two ends of described back-moving spring.
Further, described calibrating nozzle and telescopic piston are threaded connection.
Compared with prior art, the utility model has following beneficial effect: this device can fully close to roller gap region, do not worry not only to be taken the lead magnetic tape trailer collision and do not affect threading efficiency but also the nozzle of reliably working can be reached, when source of the gas is connected, telescopic piston is under stream pressure active force, overcome back-moving spring resistance, drive calibrating nozzle auto-extending to operating position; When source of the gas disconnects, under the active force of back-moving spring, telescopic piston is retracted in nozzle carrier.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
Accompanying drawing explanation
Fig. 1 is the organigram of the utility model embodiment.
In figure: 1-nozzle carrier, 11-first annular protrusion, 2-telescopic piston, 21-second annular protrusion, 3-calibrating nozzle, 4-back-moving spring, 5-check valve, 6-stud, 61-cross bar.
Detailed description of the invention
Embodiment one: as shown in Figure 1, a kind of automatic telescopic nozzle, comprise the nozzle carrier 1 of hollow tube-shape and to be nested in nozzle carrier and the telescopic piston 2 moved along its axis, described nozzle carrier 1 one end is as compressed-air actuated entrance, other end madial wall is provided with the first annular protrusion 11, the internal diameter of this first annular protrusion 11 is equal with telescopic piston 2 external diameter, described telescopic piston 2 is hollow cylinders, its one end lateral wall in nozzle carrier is provided with the second annular protrusion 21, the external diameter of this second annular protrusion 21 is equal with the internal diameter of nozzle carrier 1, the other end of described telescopic piston 2 is connected with calibrating nozzle 3, back-moving spring 4 is provided with in described telescopic piston 2, one end of this back-moving spring 4 is connected with nozzle carrier 1, its other end is connected with telescopic piston 2, when connecting to make source of the gas, telescopic piston 2 is under stream pressure active force, overcome back-moving spring 4 resistance, drive calibrating nozzle 3 auto-extending to operating position, when source of the gas disconnects, under the active force of back-moving spring 4, telescopic piston 2 is retracted in nozzle carrier.
In the present embodiment, the end face of described second annular protrusion 21, as air-flow stress surface, promotes telescopic piston 2 and moves.
In the present embodiment, the sidewall of described nozzle carrier 1 is provided with the check valve 5 being communicated with its inner space, this check valve 5 arranges on the sidewall between the first annular protrusion and the second annular protrusion, and this check valve is closed when ventilating, and opens and be in communication with the outside when dying.
In the present embodiment, in described nozzle carrier 1 and telescopic piston 2 all in be provided with bracket for allowing back-moving spring catch on, this bracket comprises the stud 6 of a hollow, cross bar 61 is provided with in stud 6, this stud 6 is threadedly connected to nozzle carrier and telescopic piston respectively, and cross bar 61 is caught at the two ends of described back-moving spring 4 respectively.
In the present embodiment, described calibrating nozzle and telescopic piston are threaded connection.
For reaching auto-extending requirement, adopting the active force utilizing air-flow itself to promote the design of telescopic piston, piston and nozzle being fixed on body by thread connection, calibrating nozzle action thereupon while piston action.Plunger designs provides circulation passage for hollow-core construction can be air-flow, the structure (i.e. the second annular protrusion) of the annular stress surface of afterbody design band.Under the aperture and physical dimension of known bleed pressure and calibrating nozzle, the amount of force of source of the gas to nozzle can be calculated, too little by design circumferentia size, accurately can meet the requirements of piston and release power.
Back-moving spring one end and piston are fixed, and the other end and nozzle carrier are fixed, the spring prestretched when original state, make telescopic piston be subject to certain stretching out resistance.When telescopic piston stretches out, spring is stretched further, and spring energy-storage is for providing spring-go energy.Spring fitting is at nozzle internal piston simultaneously, and built-in structure makes nozzle unit constructions compacter.
When plunger shaft and the direct UNICOM of atmospheric environment, can because of in the excessive situation of bleed pressure, nozzle at high speeds sprays, and produces and impacts, affect nozzle life and positional precision.Impacting for reducing, between plunger shaft and atmospheric environment, setting up an one-way valve structures.When piston stretches out, because of closed check valve, pressure raises plunger shaft, provides certain resistance, make piston slowly extend out to operating position for piston stretches out.When the gas supply is switched off, piston is retracted and is opened check valve, and plunger shaft is identical with atmospheric pressure, still can make piston fast retractile.
The foregoing is only preferred embodiment of the present utility model, all equalizations done according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
