Abstract

The utility model relates to a novel air injection gun which comprises a barrel and a pikestaff fixed on one end of the barrel, wherein the pikestaff is provided with a pneumatic pipe which is communicated with the barrel, the barrel is movably sheathed with a baffle plate, the side of the barrel, which is near an air injection port, is fixed with a wedge-shaped check block, and the size of the wedge-shaped check block is equivalent to the size of the outer end face of small circle of the brace of the baffle plate, and the barrel between the baffle plate and the pikestaff is provided with an offsetting spring; the baffle plate comprises a brace and a panel, wherein the center of the brace is provided with a guide hole, the inner diameter of the guide hole matches with the outer diameter of the barrel, the periphery of the brace is provided with 3-5 seizing teeth, and the seizing teeth extend to the side away from the brace at certain radian; the panel is fixed to the end of the brace, is a circular cambered surface and contacts with the rest spring; the inner surface of the panel is fixed with a plurality of radial ribs, and a scrap guiding slot is formed by the radial ribs and the seizing teeth. The utility model has the beneficial effect that the original barrel is additionally provided with the baffle plate and one reset spring, which can avoid the scraps like scrap iron and the like from splashing to the operator when the workpiece is cleaned, and operators are protected.

Description

A kind of novel air injection rifle

Technical field

The utility model belongs to the application tool in the industrial production, relates to a kind ofly can effectively preventing the jet gun that iron filings splash to operating personnel when the iron filings of cleaning on the workpiece.

Background technology

At present, the gun barrel of known jet gun just simply is made of a tracheae.During foreign material such as iron filings on using jet gun cleaning workpiece, gun barrel plays the effect of steering current.But, when air-flow is big slightly, can cause splashing of foreign material such as iron filings, especially when the deep hole of cleaning workpiece, easily the operator is caused unnecessary damages, fly into eyes etc. as iron filings.

Summary of the invention

The purpose of this utility model provides a kind of jet gun, and this jet gun can effectively stop foreign material such as iron filings to splash to the operator under the situation that does not influence the air gun normal function, thereby the operator is played the certain protection effect.

This novel air injection rifle, comprise gun barrel and the pikestaff that is fixed on gun barrel one end, there are pneumatic tube and gun barrel to communicate on the pikestaff, also have baroswitch on the pikestaff, it is characterized in that, on gun barrel, be movably installed with a baffle plate, side near puff prot on the gun barrel is fixed with wedge-shaped catch, the size of wedge-shaped catch is suitable with the pillar roundlet outer face size on the baffle plate, can carry out axial location to baffle plate, on the gun barrel between baffle plate and the pikestaff back-moving spring is housed.

Between back-moving spring and pikestaff, be fixed with pad.

Baffle plate comprises pillar and panel, the center of pillar is a pilot hole, the internal diameter of pilot hole and the external diameter of gun barrel match, the periphery of pillar has 3-5 to grab tooth, grabs tooth and extends to departing from pillar one side with certain radian, and panel is fixed on the end of pillar, be circular cambered surface, contact with back-moving spring, the panel inner surface is fixed with some radial rib, radial rib and grab tooth and form dregs guiding groove together.

When the cleaning workpiece; because baffle plate is near puff prot; can effectively stop foreign material such as iron filings to be splashed on operator's the body; baffle plate can move on barral of a gun; this just can satisfy the cleaning of jet gun to deep hole class workpiece, and has back-moving spring that it is resetted, so just can be under the condition that does not influence the jet gun original function; stoped foreign material such as iron filings to splash, protected the operator to the operator.

The beneficial effects of the utility model are: on former gun barrel, installed a baffle plate and a back-moving spring additional, and simple in structure, effectively stoped foreign material such as iron filings to the splashing of operator, protected the operator.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model overall structure figure.

Fig. 2 is the structural map of baffle plate.

Among the figure: 1, gun barrel, 101, wedge-shaped catch, 102, puff prot, 2, baffle plate, 201, pilot hole, 202, grab tooth, 203, pillar, 204, panel, 3, back-moving spring, 4, pikestaff, 401, pad.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is elaborated:

In Fig. 1, this novel air injection rifle, comprise gun barrel 1 and the pikestaff 4 that is fixed on gun barrel 1 one ends, there are pneumatic tube and gun barrel 1 to communicate on the pikestaff 4, also have baroswitch on the pikestaff 4, on gun barrel 1, be movably installed with a baffle plate 2, side near puff prot 102 on the gun barrel 1 is fixed with wedge-shaped catch 101, the size of wedge-shaped catch 101 is suitable with pillar 203 roundlet outer face sizes, can carry out axial location to baffle plate 2, on the gun barrel 1 between baffle plate 2 and the pikestaff 4 back-moving spring 3 is housed.Between back-moving spring 3 and pikestaff 4, be fixed with pad 401.

In Fig. 2, baffle plate 2 comprises pillar 203 and panel 204, the center of pillar 203 is a pilot hole 201, the external diameter of the internal diameter of pilot hole 201 and gun barrel 1 matches, the periphery of pillar 203 has 4 to grab tooth 202, grabbing tooth 202 has certain radian, and radian departs from panel 204 1 sides, like this can be when the aperture on the cleaning workpiece, grab tooth 202 and support pillar 203, prevent that pillar 203 end faces from stopping up aperture, influence the discharge of foreign material such as iron filings, panel 204 is fixed on the end of pillar 203, be circular cambered surface, contact with back-moving spring 3, the inner surface of panel 204 is fixed with 8 radial rib, radial rib and grab tooth 202 and form dregs guiding groove together.

Use this kind novel air injection rifle, on one's body when normal cleaning surface of the work, because baffle plate 2 is near puff prots 102, so can effectively stop foreign material such as iron filings to splash to the operator.When the deep hole of workpiece is cleared up, grabbing tooth 202 and can effectively contact on the baffle plate 2 with workpiece, prevent that pillar 203 from entering workpiece hole and stopping up the iron filings circulation passage, grabbing tooth 202 extends to departing from pillar 203 1 sides with certain radian, like this can be when the aperture on the cleaning workpiece, grab tooth 202 and support pillar 203, prevent that pillar 203 end faces from stopping up aperture, influence the discharge of foreign material such as iron filings, pillar 203 has certain-length, be used for preventing that baffle plate 2 covers workpiece hole, in order to avoid influence the outflow of foreign material such as iron filings, because baffle plate 2 can slide on gun barrel 1, so baffle plate 2 does not influence gun barrel 1 and gos deep into workpiece deep hole inside, and when gun barrel 1 takes out, can it be resetted by back-moving spring 3, dregs guiding groove can be dredged splashing of foreign material such as iron filings.

Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
