Description

Sand blasting gun convenient to adjust

Technical Field

The utility model belongs to the technical field of sand blasting guns, and particularly relates to a sand blasting gun convenient to adjust.

Background

The sandblasting refers to a process of cleaning and derusting the surface of a mechanical workpiece. The sand blasting is to form a high-speed spray beam by using compressed air as power to spray a spray material to the surface of a workpiece to be treated at a high speed, so that the appearance or the shape of the outer surface of the workpiece is changed. Due to the impact and cutting action of the abrasive on the surface of the workpiece, the surface of the workpiece obtains certain cleanliness and different roughness, and the mechanical property of the surface of the workpiece is improved. Therefore, the fatigue resistance of the workpiece is improved, the adhesive force between the workpiece and the coating is increased, the durability of the coating is prolonged, and the leveling and decoration of the coating are facilitated.

The sand blasting gun comprises a sand inlet pipe, an air inlet pipe and a sand outlet pipe, wherein the sand inlet pipe is responsible for sand inlet, the air inlet pipe is responsible for air inlet, sand is sprayed out through the sand outlet pipe in a gas mode, the sand outlet of the existing sand blasting gun is designed to the front end of the sand outlet pipe in most modes, and the sand outlet on the sheltering side of a certain workpiece cannot be sprayed out due to adjustment of the sand outlet.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defects in the prior art: the sand blasting gun convenient to adjust is provided, and can uniformly blast sand on the masking side of a workpiece.

The technical scheme adopted by the utility model is as follows:

the utility model provides a sand blasting gun convenient to adjust, is including the sand inlet pipe, intake pipe and the sand outlet pipe that connect gradually, the sand outlet pipe is flexible hose, and sand outlet pipe sand outlet is connected with the sandblast cover, and sand outlet pipe sand outlet outer wall has cup jointed fixed cover, fixed cover periphery wall is equipped with the mounting hole, be connected with the dead lever in the mounting hole.

Preferably, a sleeve hole is formed in the center of the fixed sleeve, and the wall of the sleeve hole is fixedly connected with the outer wall of the sand outlet pipe.

Preferably, the hole wall of the mounting hole is provided with an internal thread, an external thread is arranged on the outer wall of one end of the fixing rod, and the fixing rod is connected with the mounting hole through the internal thread and the external thread.

Preferably, the bottom end face of the fixed sleeve is provided with a fixed hole, and the wall of the fixed hole is provided with threads.

In summary, due to the adoption of the technical scheme, the utility model has the beneficial effects that:

1. the sand outlet pipe provided by the utility model adopts the flexible hose, can be freely adjusted, can uniformly sand blast the masking side of the workpiece, and solves the problem that sand blast cannot be carried out on the masking side of the workpiece in the prior art.

2. In addition, the sand blasting effect is better and the use is more convenient due to the matching use of the fixed sleeve and the fixed rod.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and embodiments.

In the case of the example 1, the following examples are given,

referring to fig. 1-2, a sand blasting rifle convenient to adjust, including the sand inlet pipe, intake pipe and the sand outlet pipe 3 that connect gradually, sand outlet pipe 3 is flexible hose, and 3 sand outlets of sand outlet pipe are connected with

sandblast cover

1, and 3 sand outlets of sand outlet pipe have cup jointed fixed cover 2, fixed cover 2 periphery walls are equipped with mounting hole 5, the 5 in-connection of mounting hole has dead lever 4.

Wherein, the center of the fixed sleeve 2 is provided with a trepanning 7, and the hole wall of the trepanning 7 is fixedly connected with the outer wall of the sand outlet pipe 3.

Wherein, 5 pore walls of mounting hole are equipped with the internal thread, 4 one end outer walls of dead lever are equipped with the external screw thread, and dead lever 4 is connected through internal thread and external screw thread with mounting hole 5.

Wherein, fixed cover 2 bottom face is equipped with fixed orifices 6, the pore wall of fixed orifices 6 is equipped with the screw thread.

Referring to fig. 4, one side of the workpiece tube 9 close to the mounting plate 8 is a workpiece masking side, in the first case, when sand blasting is required to be performed on the workpiece masking side, the fixing rod 4 is connected with the mounting hole 5, and sand blasting operation can be started after the sand blasting cover 1 is stretched into the masking side by holding the fixing rod 4 by hand;

the side of the workpiece pipe 9, which is far away from the mounting plate 8, is the non-masking side of the workpiece, in the second case, when the non-masking side of the workpiece needs to be subjected to sand blasting, the fixing rod 4 is separated from the mounting hole 5, then the fixing rod 4 is connected with the fixing hole 6, and finally the sand blasting cover 1 is aligned to the non-masking side of the workpiece to be subjected to sand blasting by holding the fixing rod 4 by hand.

Therefore, the fixing sleeve 2 and the fixing rod 4 can be matched for use under the two conditions, so that the sand blasting effect is better and the use is more convenient.
