A sandblasting pipe is sleeved on one end of the hinged part.

[0007] In some embodiments, the sleeve socket includes an extension and a mounting portion, wherein the sandblasting pipe is fitted onto the extension with an interference fit, and the mounting portion is used to assemble the sleeve socket into the through hole.

[0008] In some embodiments, the sleeve socket and the inner wall of the through hole are provided with threads, and the sleeve socket is fixed in the through hole by threaded connection.

[0009] In some embodiments, the end of the mounting portion is formed with a cross groove or an external hexagonal protrusion for easy screwing.

[0010] In some embodiments, the sleeve socket is connected to the through hole by an elastic snap, and a groove is provided on the outer edge of the through hole to facilitate the insertion of a tool to pry out the sleeve socket.

[0011] In some embodiments, the sleeve socket is fitted into the through hole by screws.

[0012] In some embodiments, the sandblasting pipe extends into the flow regulating disc, and the flow regulating disc is provided with a control structure for controlling the flow rate and velocity of sand particles passing through the sandblasting pipe.

[0013] The beneficial effects of this application are as follows: the detachable sleeve socket allows for convenient and quick removal of the sleeve socket and the sandblasting pipe from the threaded side for replacement.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application. In addition, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those of ordinary skill in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection of this application.

[0027] In the embodiments of this application, please refer to Figure 1-10 As shown, the quick-change structure for the sandblasting pipe of this sandblasting machine mainly includes a sandblasting tank 1 and a sandblasting tank connecting seat 2. The sandblasting tank 1 is threaded 7 to the sandblasting tank connecting seat 2. A flow regulating disc 3 is hinged on the sandblasting tank connecting seat 2. The sandblasting tank connecting seat 2 includes an integral threaded part 201 and a hinged part 202. The threaded part 201 and the hinged part 202 are connected through a through hole 4 at the center. A sleeve socket 5 is detachably provided in the through hole 4 on one side of the threaded part 201. The sleeve socket 5 passes through the through hole 4 and extends into the hinged part 202. A sandblasting pipe 6 is sleeved on one end of the sleeve socket 5 in the hinged part 202. By removing the sleeve socket 5 from the through hole 4, the sandblasting pipe 6 on the sleeve socket 5 can be replaced. Compared with the integral sleeve socket 5, the replacement of the sandblasting pipe 6 is more convenient.

[0028] The following will continue to describe some preferred / improved embodiments based on the above embodiments. Any one of the following embodiments can be selected, or multiple embodiments can be combined.

[0029] like Figure 5-6As shown, the sleeve socket 5 includes an extension 501 and a mounting part 502. The sandblasting pipe 6 is fitted onto the extension 501 with an interference fit. The mounting part 502 is used to assemble the sleeve socket 5 into the through hole 4. The sandblasting pipe 6 is an elastic rubber tube, one end of which is fitted onto the extension 501 and pressed against the extension 501. In addition, the sleeve socket 5 has an internally hollow structure so that the abrasive (sand particles) and gas in the sandblasting can 1 can be transported out from the sleeve socket 5 to the sandblasting pipe 6.

[0030] In the first embodiment, as Figure 7-8 As shown, the sleeve socket 5 and the inner wall of the through hole 4 are provided with threads 7, and the sleeve socket 5 is fixed in the through hole 4 by the threads 7.

[0031] Specifically, to facilitate the disassembly and assembly of the sleeve socket 5, the end of the mounting part 502 is formed with a cross groove 8 or an external hexagonal protrusion 9 for easy screwing.

[0032] like Figure 9 As shown, in the second embodiment, the sleeve socket 5 is connected to the through hole 4 by an elastic snap. The outer edge of the through hole 4 is provided with a groove 10, which is used to facilitate the insertion of tools to pry out the sleeve socket 5. The snap connection is achieved by using the elastic deformation of the sleeve socket 5 to generate friction or nesting action.

[0033] In the third embodiment, as Figure 10 As shown, the sleeve socket 5 is assembled in the through hole 4 by screws 11.

[0034] like Figure 1 As shown, the sandblasting pipe 6 extends into the flow regulating plate 3, and the flow regulating plate 3 is provided with a control structure to control the flow rate and velocity of sand particles passing through the sandblasting pipe 6.

[0035] This application utilizes a detachable sleeve socket 5, which allows for easy and quick replacement of the sandblasting pipe 6 when the sandblasting canister 1 needs to be removed and the sleeve socket 5 can be taken out from the screw connection 201 side to replace the sandblasting pipe 6 on its extension 501. This makes maintenance simple and convenient.
