[0021] In order to more clearly understand the above purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the drawings and examples.It should be noted that the embodiments of the present application and the features in the examples can be combined with each other without conflict.

[0022] In the following description, a lot of specific details are set forth in order to facilitate a thorough understanding of the utility model, but the utility model can also be implemented in other ways different from the description herein, therefore, the utility model is not limited to the specific embodiments disclosed in the following disclosure.

[0023] As Figures 1-4 A switching device for sand blasting nozzle, including known spray head 16 and several different aperture sand blasting nozzle body 5 for cooperating with spray head 16, spray head 16 surface mounting has fixed frame 1, fixed frame 1 one side is provided with connecting disc 2, the other side is provided with two parallel distribution and located spray head 16 head both sides clamping rail 6, connecting disc 2 edge rotationally connected with gear ring 4, gear ring 4 back to fixed frame 1 one side edge fixedly connected with several annular array distribution and used for with sand blasting nozzle body 5 side edge plug-in clamping seat 14, as Figure 1As shown, by driving the gear ring 4 to rotate, the rotating of the one of the seats 14 on the gear ring 4 to the position directly below is realized, and the sand blasting nozzle body 5 mounted on the surface thereof is synchronously transferred to the position directly below. The end surface of the connecting disc 2 is fixedly connected with the electric telescopic rod 9 arranged along the center line direction of the spray head 16. The telescopic end of the electric telescopic rod 9 is fixedly connected with the magnetic block 10 magnetically attracted to the end of the sand blasting nozzle body 5. The end surface of the sand blasting nozzle body 5 transferred to the position directly below will not fall off due to the magnetic attraction with the magnetic block 10. The fixed frame 1 is fixedly connected with the electric push rod 7 between the two clamping rails 6. The telescopic end of the electric push rod 7 is telescopically extended along the length direction of the clamping rail 6 and is also fixedly connected with the sand blasting nozzle body 5 inserted into the seat 14 on the side edge thereof. The sand blasting nozzle body 5 attracted by the magnetic block 10 will be lowered to the position between the two clamping rails 6 along with the extension of the electric telescopic rod 9 and the magnetic block 10. Before the lowering of the sand blasting nozzle body 5, the extension of the electric push rod 7 is used to realize the movement of the seat 14 at the telescopic end thereof between the two clamping rails 6 until the seat 14 is aligned with the seat 14 directly below on the connecting disc 2. Therefore, the sand blasting nozzle body 5 lowered along with the magnetic block 10 will be transferred to the surface of the seat 14 at the telescopic end of the electric push rod 7 until the sand blasting nozzle body 5 is completely separated from the seat 14 on the connecting disc 2. Then, the retraction of the electric push rod 7 is used to realize the movement of the sand blasting nozzle body 5 inserted into the seat 14 to the head of the spray head 16, so that the sand blasting nozzle body 5 with different diameters can be installed. Conversely, when disassembling, the extension of the electric push rod 7 is used to push the sand blasting nozzle body 5 to the position directly below the connecting disc 2, and then the adsorption of the magnetic block 10 is used to realize the re-entry of the sand blasting nozzle body 5 into the seat 14 on the connecting disc 2 along with the rising of the magnetic block 10.

[0024] Further, the fixed frame 1 is extended to the inner side of the gear ring 4 and is fixedly connected with the motor 11. The main shaft of the motor 11 is fixedly connected with the spur gear 12 engaged with the inner side of the gear ring 4. The rotation of the spur gear 12 driven by the motor 11 is used to realize the rotation of the gear ring 4 engaged therewith to realize the position exchange of the sand blasting nozzle bodies 5 on the connecting discs 2. The outer side of the gear ring 4 is gap-fitted with the blocking ring 3 connected with the fixed frame 1. The side of the blocking ring 3 facing the head of the spray head 16 is provided with the notch 13. The side edge of the sand blasting nozzle body 5 is penetrated through the notch 13. The other areas of the blocking ring 3 except the notch 13 can prevent the sand blasting nozzle body 5 mounted in the seat 14 on the surface thereof from falling off when the gear ring 4 rotates. The notch 13 is provided with the magnetic block 10. Therefore, even if the sand blasting nozzle body 5 rotates to the position of the magnetic block 10, the sand blasting nozzle body 5 will not fall off due to the adsorption of the magnetic block 10. Conversely, the notch 13 can ensure that the sand blasting nozzle body 5 is lowered along with the magnetic block 10.

[0025] Further, the side edge of the sand blasting nozzle body 5 is fixedly connected with a clamping strip 15 inserted with the clamping seat 14, and the side surface of the sand blasting nozzle body 5 is also fixedly connected with two clamping blocks 8 symmetrically about the clamping strip 15 and inserted with two clamping rails 6 respectively, the insertion of the clamping block 8 and the clamping rail 6 can ensure that the relative position of the sand blasting nozzle body 5 and the nozzle 16 in the use state is fixed, the clamping seat 14 at one end of the center of the connecting disc 2 and the top end of the clamping seat 14 on the telescopic end of the electric push rod 7 are both provided in a penetrating mode, the clamping strip 15 and the clamping block 8 are both provided in a T-shaped mode, the penetrating mode ensures that the sand blasting nozzle body 5 can move freely in the position between the clamping seat 14 on the electric telescopic rod 9 and the clamping seat 14 on the electric push rod 7 in the aligned state, and the end surface of the sand blasting nozzle body 5 and the end surface of the magnetic block 10 have the same arc and are in sliding fit.

[0026] Working principle, when the corresponding aperture sand blasting nozzle body 5 needs to be used, the motor 11 is only needed to drive the straight gear 12 to rotate, then the tooth ring 4 connected in meshing mode drives the connecting disc 2 to rotate until the corresponding aperture sand blasting nozzle body 5 moves to the gap 13 and is attracted by the magnetic block 10, the electric push rod 7 is elongated to realize that the clamping seat 14 on the telescopic end moves between the two clamping rails 6 until it is aligned with the clamping seat 14 directly below on the connecting disc 2, the electric telescopic rod 9 is elongated to make the magnetic block 10 descend, the sand blasting nozzle body 5 descending with the magnetic block 10 will be transferred to the surface of the clamping seat 14 on the telescopic end of the electric push rod 7 until the sand blasting nozzle body 5 is completely separated from the clamping seat 14 on the connecting disc 2, then the electric push rod 7 is retracted to realize that the clamping seat 14 on the telescopic end drives the sand blasting nozzle body 5 inserted with the clamping seat 14 to move to the head of the nozzle 16, so that the sand blasting nozzle body 5 with different apertures can be installed.

[0027] The wiring diagram of the electric telescopic rod 9, the motor 11 and the electric push rod 7 in the utility model belongs to the common knowledge in the field, the working principle is a known technology, and the model is selected according to the actual use, so the control mode and the wiring arrangement of the electric telescopic rod 9, the motor 11 and the electric push rod 7 will not be explained in detail.
