Abstract

The utility model discloses a powerful wind blowing gun, which comprises a gun body, a wrench, a gun barrel, a piston and a sealing ring, wherein the wrench and the gun barrel are mounted on the gun body; the piston is mounted in the gun body after the sealing ring is mounted on the piston, and is movably arranged inside the gun body in a sleeving manner; a spring is arranged at the top end of the piston; a screw cap which can be dismounted conveniently is arranged at the top of the spring, and compresses the spring; the top of the screw cap is exposed out of the gun body; and the spring is propped against the piston. The screw cap and the spring, as well as the spring and the piston are piled up simply, so that after the screw cap is unscrewed, the spring and the piston can be easily taken out for replacement. The utility model has simple structure, that is, the screw cap can be disassembled and assembled easily only by putting the piston inside the gun body and then using the spring for compressing and the screw cap for covering. Therefore, after the piston is abraded, all that is needed is to unscrew the screw cap, and the wind blowing gun can be reused after the piston is replaced. The utility model can be reused for a long time, reduces material waste, and lowers the use cost.

Description

A kind of powerful blowing rifle

Technical field

The utility model relates to a kind of dust burnisher, is specifically related to a kind of powerful blowing rifle.

Background technology

The blowing rifle is the burnisher that arrives commonly used in the industrial production, such as giving machinery, workpiece or other article dedusting or removing foreign material etc., its basic principle is that extraneous air is sucked, convert high pressure draught moment ejection again to, the attachments such as dust that impulse force by air-flow will stick to article surface blow off, need not therefore can not cause damage to article as using the direct contact article surface of rag.At present, the blowing rifle of Shi Yonging on the market, its structure roughly is that piston is installed in rifle body inside, moves and controls air blowing by withholding the spanner control piston, and the duty ratio of piston is bigger in use, can cause certain damage, piston is damaged to a certain degree just have been scrapped, and the piston in the existing blowing rifle all is in disposable being enclosed in, and has carried out and just can not change easily, therefore piston has been broken, and whole blowing rifle also just is done for basically.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of simple in structure, easy accessibility, can change the brute force blowing rifle of piston flexibly.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of powerful blowing rifle, comprise rifle body, spanner, gun barrel, piston and sealing ring, spanner and gun barrel are installed on the rifle body, piston is located in the rifle body after loading onto sealing ring, it is characterized in that: described piston is movably set in rifle body inside, in other words, piston just is placed in the rifle body, it is not fixed; Piston tip is provided with spring, the spring top be provided with can be for convenience detach nut, the nut compressing spring, expose in external of rifle at the nut top, spring props up piston.Nut and spring, spring and piston all are simple the accumulation, after nut is turned on, just can take out spring and piston easily, thereby can change piston.

Further, described spiro cap is provided with the sealing ring lid and is pressed on the rifle body, and this sealing ring is set below nut, can play the effect of dual-seal to rifle body inner high voltage gas.

The utility model is simple in structure, just by the piston activity being positioned over rifle body inside, is covered by spring compression, nut again, and nut is dismounting easily, therefore, behind piston wear, only needs nut is turned on, and piston is more changed and can be reused.Therefore, the utility model can be reused, reduce waste of material for a long time, reduce use cost.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is a piston package assembly decomposing schematic representation.

Among the figure, 1 is the rifle body, and 2 is spanner, and 3 is gun barrel, and 4 is nut, and 5 is piston, and 6 is spring, and 7 is sealing ring.

The specific embodiment

In the present embodiment, see figures.1.and.2, described powerful blowing rifle comprises rifle body 1, spanner 2, gun barrel 3, piston 5 and sealing ring 7, and spanner 2 and gun barrel 3 are installed on the rifle body 1, and piston 5 is located in the rifle body 1 after loading onto sealing ring 7; Piston 5 is movably set in rifle body 1 inside, and in other words, piston 5 just is placed in the rifle body 1, it is not fixed; Piston 5 tops are provided with spring 6, spring 6 tops be provided with can be for convenience detach nut 4, nut 4 holddown springs 6, expose in rifle body 1 outside at nut 4 tops, spring 6 props up piston 5.Nut 4 and spring 6, spring 6 and piston 5 all are simple the accumulation, after nut 4 is turned on, just can take out spring 6 and piston 5 easily, thereby can change piston 5.

Nut 4 sheathed sealing ring 7 bonnets are pressed on the rifle body 1, and this sealing ring 7 is set below nut 4, can play the effect of dual-seal to rifle body 1 inner high voltage gas.

Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
