The high-pressure conduit 1 is slidable in a straight line up and down. When the extrusion plate 5 slides downward, the high-pressure conduit 1 can be squeezed to close the high-pressure conduit 1. When the extrusion plate 5 slides upward, the extrusion plate 5 can be separated from the contact with the high-pressure conduit 1 to make the high-pressure conduit 1 unobstructed. This solves the problem that the high-pressure conduit 1 of the respirator in the prior art is not convenient to control the opening and closing of the high-pressure conduit 1 during actual use, resulting in limited flexibility of the high-pressure conduit 1 during actual use. Through the provision of two quick connectors 2, the high-pressure conduit 1 can be quickly installed, the operation is simple and convenient, and the disassembly, assembly and replacement of the high-pressure conduit 1 are convenient.

[0025] In this embodiment, the high-pressure conduit 1 is a rubber tube, which is soft and has a long service life.

[0026] In this embodiment, the extrusion assembly includes a sliding assembly, a rack 14, a rotating column 13, a gear 15, a first rotating rod 16 and a second rotating rod 17. The sliding assembly is arranged at the top of the inner cavity of the casing 3, the rack 14 is arranged at the bottom of the sliding assembly, the left and right ends of the rotating column 13 are respectively rotatably connected to the left and right sides of the inner cavity of the casing 3 through bearings, the gear 15 is fixedly sleeved on the outer wall of the rotating column 13, the first rotating rod 16 is fixedly sleeved on the outer wall of the rotating column 13, one end of the second rotating rod 17 is hinged on the top of the lifting plate 4, and the other end of the second rotating rod 17 is hinged on the end of the first rotating rod 16 away from the rotating column 13. When the sliding assembly drives the rack 14, due to the rack 14 and the gear 1 5 is meshed with each other, so when the rack 14 slides, the gear 15 can drive the rotating column 13 to rotate, so that the first rotating rod 16 and the second rotating rod 17 push the lifting plate 4 and the squeezing plate 5 to slide downward along a straight line under the limiting action of the telescopic cylinder 6 and the telescopic rod 7, so that the squeezing plate 5 squeezes the outer wall of the high-pressure conduit 1, causing the high-pressure conduit 1 to deform and close. When the squeezing plate 5 slides upward, the squeezing plate 5 can be separated from the contact with the high-pressure conduit 1, so that the high-pressure conduit 1 is unobstructed, which solves the problem that the high-pressure conduit 1 of the respirator in the prior art is not easy to control the opening and closing of the high-pressure conduit 1 during actual use, resulting in limited flexibility of the high-pressure conduit 1 during actual use.

[0027] In this embodiment, the rack 14 is meshed with the gear 15 , so that when the rack 14 slides, the gear 15 drives the rotating column 13 to rotate.

[0028] In this embodiment, the sliding assembly includes a screw rod 10, a knob 11, a slide plate 12 and a limit assembly. One end of the screw rod 10 is rotatably connected to the rear side of the inner cavity of the casing 3 through a bearing, and the other end of the screw rod 10 extends to the front end of the casing 3 and is fixedly connected to the knob 11.

The limit assembly is arranged at the top of the inner cavity of the casing 3 and is fixedly connected to the top of the slide plate 12. The knob 11 is rotated to make the knob 11 drive the screw rod 10 to rotate. Under the action of the rotational force of the outer wall thread of the screw rod 10, when the screw rod 10 rotates, the slide plate 12 can drive the rack 14 to slide under the limiting action of the limiting groove 18 and the limiting block 19.

[0029] In this embodiment, the limit assembly includes a limit groove 18 and a limit block 19. The limit groove 18 is opened at the top of the inner cavity of the casing 3. The limit block 19 can be slidably embedded in the inner cavity of the limit groove 18 and fixedly connected to the top of the slide plate 12. Under the interaction between the limit groove 18 and the limit block 19, the sliding block can be prevented from rotating with the screw rod 10 when the screw rod 10 rotates, thereby improving the stability of the sliding assembly during use.

[0030] In this embodiment, the inner cavity of the limiting groove 18 is matched with the outer wall of the limiting block 19 and both are in a "T" shape, so that one end of the limiting block 19 can always remain embedded in the inner cavity of the limiting groove 18, thereby improving the stability of the limiting assembly during use.

The other end of the telescopic rod 7 is fixedly connected to a corner of the top of the lifting plate 4. The two connecting assemblies are respectively arranged on the left and right sides of the inner wall of the telescopic cylinder 6 and are respectively fixedly connected to the left and right sides of the outer wall of the telescopic rod 7. Under the joint action of the telescopic cylinder 6 and the telescopic rod 7, the lifting plate 4 can always slide up and down along a straight line, thereby improving the stability of the device when in use.

[0032] In this embodiment, the connecting component includes a slide groove 8 and a moving block 9. The slide groove 8 is opened on the inner wall of the telescopic cylinder 6. One end of the moving block 9 can be slidably embedded in the inner cavity of the slide groove 8. The other end of the moving block 9 is fixedly connected to the outer wall of the telescopic rod 7. Under the joint action of the slide groove 8 and the moving block 9, one end of the telescopic rod 7 can always be kept inserted in the inner cavity of the telescopic cylinder 6, thereby improving the stability of the device during use.

[0033] In this embodiment, the inner cavity of the slide groove 8 is adapted to the outer wall of the moving block 9 and both are dovetail-shaped, so that one end of the moving block 9 can always remain embedded in the inner cavity of the slide groove 8, preventing the moving block 9 from escaping from the inner cavity of the slide groove 8, thereby improving the stability of the device during use.

[0034] The use method and advantages of the utility model: When in use, the working process is as follows:

[0035] By setting the two quick connectors 2, the high-pressure conduit 1 can be quickly installed, the operation is simple and convenient, and the disassembly, assembly and replacement of the high-pressure conduit 1 is convenient. The knob 11 is rotated to make the knob 11 drive the screw rod 10 to rotate. Under the action of the rotational force of the outer wall thread of the screw rod 10, when the screw rod 10 rotates, the slide plate 12 can drive the rack 14 to slide under the limiting action of the limiting groove 18 and the limiting block 19. Since the rack 14 is meshed with the gear 15, when the rack 14 slides, the gear 15 can drive the rotating column 13 to rotate, so that the first rotating rod 16 can rotate with the rotation of the first rotating rod 16. The second rotating rod 17 pushes the lifting plate 4 and the squeezing plate 5 to slide downward along a straight line under the limiting action of the telescopic cylinder 6 and the telescopic rod 7, so that the squeezing plate 5 squeezes the outer wall of the high-pressure conduit 1, causing the high-pressure conduit 1 to deform and close. When the squeezing plate 5 slides upward, the squeezing plate 5 can be separated from the contact with the high-pressure conduit 1, so that the high-pressure conduit 1 is unobstructed, which solves the problem that the high-pressure conduit 1 of the respirator in the prior art is not convenient to control the opening and closing of the high-pressure conduit 1 during actual use, resulting in limited flexibility of the high-pressure conduit 1 during actual use.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model.
