Pistol nozzle

A pistol nozzle is designed to emit a compressed fluid and is formed of a main body and a telescopic barrel set. The main body is provided with a trigger, a retaining hook, a fluid emitting end, and a fluid admission end which is fastened to a fluid pipe. The telescopic barrel set is fastened to the fluid emitting end of the main body and is formed of a fastening mount, a plurality of telescopic tubes, a plurality of stop members, and a plurality of washers. The fastening mount is fastened at one end to the fluid emitting end of the main body and is provided at the opposite end to a stepped and threaded portion. The telescopic tubes are fastened at the base end thereof to the stepped and threaded portion of the fastening mount at such time when they are collapsed together. The telescopic tubes are extended in conjunction with the stop members and the washers.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates generally to a pistol nozzle, and more particularly to a pistol nozzle having a telescopic barrel, through which a compressed fluid is emitted.

2. Description of Related Art

As shown in FIGS. 1 and 2 , a pistol nozzle of the prior art has a main body 10 which is provided with a trigger 101 , and a handle 102 connected with a fluid pipe. The main body 10 is fastened at the front end to a telescopic barrel 11 , through which the fluid is emitted. The telescopic barrel 11 has a plurality of sections that slide into each other. The telescopic barrel 11 of the prior art pistol nozzle is defective in design because its outermost section is apt to be forced out by the compressed fluid at the time when the telescopic barrel 11 is at work in the collapsed state. As a result, the outermost section of the telescopic barrel 11 in action may come in contact with a foreign object, thereby resulting in contamination of the telescopic barrel 11 by the foreign object.

BRIEF SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a pistol nozzle with a telescopic barrel free of the drawback of the prior art pistol nozzle described above.

In keeping with the principle of the present invention, the foregoing objective of the present invention is attained by a pistol nozzle comprising a main body, a telescopic barrel having a plurality of sections, and a locating member for preventing the telescopic barrel from being displaced by the force of the compressed fluid flowing through the telescopic barrel.

The features, functions, and advantages of the present invention will be more readily understood upon a thoughtful deliberation of the following detailed description of a preferred embodiment of the present invention with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

As shown in FIGS. 3-10 , a pistol nozzle embodied in the present invention comprises a main body 20 and a telescopic barrel set 23 .

The main body 20 is provided with a trigger 21 , a retaining hook 22 , a fluid emitting end 201 , and a fluid admission end 202 which is fastened to a fluid pipe 24 .

The pistol nozzle of the preferred embodiment of the present invention is characterized by the telescopic barrel set 23 , which is fastened to the fluid emitting end 201 of the main body 20 and is formed of a fastening mount 25 , a plurality of telescopic tubes 29 , a plurality of stop members 26 , and a plurality of washers 27 .

The fastening mount 25 is provided at one end with outer threads, which are engaged with the inner threads of the fluid emitting end 201 of the main body. The fastening mount 25 is further provided at the opposite end with a stepped and threaded portion.

The telescopic tubes 29 are different in diameter from one another and are fastened at the base end thereof to the stepped and threaded portion of the fastening mount 25 at such time when the telescopic tubes 29 are collapsed together. The telescopic tubes 29 are provided at the base end with inner threads, and at the outer end with outer threads. When the telescopic tubes 29 are extended, they are fastened end to end such that the outer threads of the outer end of one telescopic tube 29 are engaged with the inner threads of the base end of another telescopic tube 29 in conjunction with a stop member 26 and a washer 27 . The stop members 26 are intended to position the telescopic tubes 29 and are provided with inner threads engageable with the outer threads of the telescopic tubes 29 . The washers 27 are intended to prevent the leaking of the compressed fluid.

As shown in FIG. 9 , the telescopic tube 29 is provided at an expansion end thereof with a stop sleeve 28 fitted thereover.

The embodiment of the present invention described above is to be regarded in all respects as being merely illustrative and not restrictive. Accordingly, the present invention may be embodied in other specific forms without deviating from the spirit thereof. The present invention is therefore to be limited only by the scope of the following appended claims.
