DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0030] Depend on Figure 1-6 The present invention discloses a digital power supply structure for multi-gas path cutting and gouging, comprising a chassis 1, a circuit board 4 installed in the chassis 1, and a protective box 5 covering the circuit board 4. The use of the protective box 5 can protect the circuit board 1 and prevent dust from being contaminated on the circuit board 1. The protective box 5 is fixedly connected to the chassis 1. A toggle block 12 is also provided in the chassis 1. The lower end of the toggle block 12 contacts the upper end of the second controller 3, and its upper end extends to the upper end of the chassis 1. A first controller 2 and a second controller 3 are installed inside the chassis 1. The first controller is installed on the bottom wall of the chassis 1. The first controller 2 is used to control the main valves of multiple gas paths to control the on and off of the gas paths. The second controller 3 is installed on the side wall of the chassis 1. There are multiple second controllers for controlling the on and off of a single gas path.

[0031] The second controller 3 includes a first connecting tube 301, a second connecting tube 305 and a third connecting tube 306. The first connecting tube 301 and the second connecting tube 305 are rotatably connected together, and the second connecting tube 305 and the third connecting tube 306 are rotatably connected together. The toggle block 12 cooperates with the third connecting tube 306.

[0032] The inner wall of the first connecting tube 301 is provided with an inclined surface 302, on which a gasket 303 is provided. An extension tube 304 is fixedly connected to one end of the second connecting tube 305, with the free end of the extension tube 304 resting on the inclined surface 302. This allows the user to conveniently and tightly connect the gas pipeline to the second connecting tube 305 when the device is in use. A first valve disc 307 is fixedly connected to the end of the second connecting tube 305 away from the first connecting tube 301. A second valve disc 308 is fixedly connected to the third connecting tube 306. Both the first and second valve discs 307 and 308 have through holes 309. When the through holes 309 on the first valve disc 307 and the through holes 308 on the second valve disc 308 are aligned, the gas path is open; when the through holes 309 on the first valve disc 307 and the through holes 308 on the second valve disc 308 are intersecting, the gas path is closed. A fixing rod 310 is fixedly connected to the second connecting tube 305, the other end of which is fixedly connected to the side wall of the chassis 1.

[0033] The toggle block 12 includes a first horizontal portion, a second horizontal portion, and a connecting portion. The first horizontal portion is fixedly connected to the upper end of the connecting portion and is located outside the chassis 1. The second horizontal portion is fixedly connected to the lower end of the connecting portion. A rack is provided on the lower end surface of the second horizontal portion. The surface of the third connecting tube 306 is provided with an annular tooth pattern 311. When the toggle block 12 slides horizontally, the rack on the toggle block 12 can cooperate with the tooth pattern, thereby rotating the third connecting tube 306, thereby causing the second valve plate 308 on the third connecting tube 306 to stagger with the through hole 309 on the first valve plate 307, thereby changing the on / off state of the air path.

[0034] As a first connection mode between the first connecting pipe 310 and the second connecting pipe 305 , the first connecting pipe 301 and the second connecting pipe 305 are threadedly matched.

[0035] As a second connection method between the first connecting tube 310 and the second connecting tube 305: the first connecting tube 301 is rotatably provided with a rotating ring 312, and the second connecting tube 305 is fixedly connected with a connecting block 313. The rotating ring 312 is fixed with an extension block. The extension block is annular and a ring groove is provided on the connecting block 313. The extension block and the ring groove are threaded together.

[0036] The protective box 5 is fixedly connected to the chassis 1 by screws. The protective box 5 is fixedly connected to the chassis 1 by gluing. The above two methods of installing the protective box 5 can facilitate the user's implementation. Of course, the user can also implement it in other ways.

[0037] The chassis 1 is provided with an air inlet, a power socket and an air outlet, which are arranged in sequence from top to bottom.

[0038] A case cover 6 is provided on one side of the chassis 1, and a cover plate 7 is provided inside the case cover 6. The chassis 1 is connected to the case cover 6 by screws, and when the case cover 6 is connected to the chassis 1, the cover plate 7 can cover the protective box 5. That is, after the chassis 1 and the case cover 6 are assembled, the cover plate 7 can cover the protective box 5 to close the protective box.

[0039] A support rod 8 is fixed to the cover plate 7, and a mounting block 9 is fixed to the box cover 6. The end of the support rod 8 is threadedly connected to the mounting block 9. When the box cover 6 is removed, the user can remove the support rod 8, so that those skilled in the art can implement the technical solution on existing equipment.

[0040] A wire threading frame 10 is fixedly connected to the support rod 8, and an elastic band 11 is provided in the wire threading frame 10. When the present device is implemented, the power cord in the chassis 1 can pass through the wire threading frame 10, thereby bundling the cable to a certain extent. The use of the elastic band 11 can also fix the position of the cable to a certain extent.
