Detailed Description

As shown in fig. 1-3, the high-pressure sand blasting gun of the present invention includes an air inlet 1, a sand inlet 2 and a sand blasting gun body 3, and the sand blasting gun body 3 has a communicating air inlet 30, a sand inlet 31 and a sand outlet 32. The working principle is as follows: when air inlet interface 1 inserts air inlet 30 air feed, arouse the gas negative pressure in sandblast rifle body 3 inside to the sand material suction that will follow sand inlet 31 and get into, make the sand material reach the hypervelocity through gaseous acceleration after the sand material suction, the sand material is the sector from tubaeform sandblast mouthful cover 4 blowout shape, sandblast rifle body 3 is aimed at and is substituted the machined part from sand outlet 32 blowout gravel like this, thereby realizes the purpose of even sandblast processing.

Because can arouse the subatmospheric pressure during the air feed of interface 1 of admitting air, attract the sand material, and at the in-process of sand material suction, partial sand material can have horizontal speed, and leads to partial sand material to pass through the gas and strike on sandblast rifle body 3 with higher speed, leads to the wearing and tearing of sandblast rifle body 3 easily, in order to solve this problem, the utility model discloses be equipped with two symmetrical sand inlets 31 of each other at sandblast rifle body 3, be equipped with in being used for protecting sandblast rifle body 3 not by the direct rifle body core cover 5 that strikes of sand material, rifle body core cover 5 top lateral wall is equipped with core cover breach 50, and core cover breach 50 aligns into sand mouth 31, and the top of rifle body core cover 5 communicates with each other with air inlet 30, and the sand material gets into rifle body core cover 5 from core cover breach 50, and partial sand material strikes on the inner wall of rifle body core cover 5 to protection sandblast rifle body 3 is not damaged by direct striking.

In order to fix the rifle body core cover 5, make things convenient for rifle body core cover 5 to change, can play the effect of protection to rifle body core cover 5 simultaneously, the utility model discloses be connected with sandblast mouthful cover 4 at 3 lower extremes of the sandblast rifle body, rifle body core cover 5 is fixed in the sandblast rifle body 3 through sandblast mouthful cover 4, and when rifle body core cover 5 wearing and tearing, removable sandblast mouthful cover 4, and then conveniently change rifle body core cover 5, sandblast mouthful cover 4 can play fixed effect to rifle body core cover 5 simultaneously.

In order to fix the gun core sleeve 5 better, the utility model discloses on the basis above, still be equipped with the ring channel in the bottom of the sandblast gun body 3, and the upper end of sandblast mouthful cover 4 has annular protrusion 40, and the annular protrusion 40 of sandblast mouthful cover 4 matches and establishes in the ring channel of the sandblast gun body 3 to make things convenient for the installation of sandblast mouthful cover 4.

In order to prevent the sand from being sprayed at four positions due to impact in the sand blasting process, the horn-shaped sand blasting port sleeve 4 can effectively control the spraying track of the sand, and can achieve the spraying effects of being more uniform and larger in area.

In order to achieve the effect of sealing the inside of the device, the O-shaped ring is sleeved outside the gun body core sleeve 5 of the utility model and is positioned between the sand blasting mouth sleeve 4 and the sand blasting gun body 3, thus preventing dust from entering and preventing the sand blasting mouth sleeve 4 from sliding; in addition, the sand blasting process has large vibration, and the O-shaped ring 6 is arranged to achieve the shock absorption effect.

In order to make the 5 stand wear and tear effects of rifle body core cover better, the utility model discloses a rifle body core cover 5 is made for ceramic material, and ceramic material is also cheaper for other materials, and the price/performance ratio is higher.

The sand blasting port sleeve 4 is a nylon sleeve, has low price, good wear resistance and easy processing compared with other materials, and can better fix the gun core sleeve 5.
