[0030] In order to further understand the content of the utility model, the utility model is described in detail with reference to the accompanying drawings.

[0031] Reference Figure 1-4 The utility model provides an embodiment: a quick-opening pressure vessel door opening rotation auxiliary device, including a pressure vessel body 1, a container cover 7 is rotatably connected to the rear side of the inner wall of the top end of the pressure vessel body 1, a receiving groove 10 is opened in the middle of the top end, a fixed shaft 14 is fixedly connected to the middle of the inner wall of the receiving groove 10, an inclined rod 5 is rotatably connected to the outer wall of the fixed shaft 14, and the bottom end of the support plate 4 is fixedly connected to the rear side of the top end of the pressure vessel body 1.

[0032] Specifically, both the front and rear sides of the container cover 7 are provided with arc treatments to be tightly connected to the inner wall of the pressure container body 1 , and the receiving groove 10 is used to receive the inclined rod 5 , and the inclined rod 5 moves and rotates on the inner wall of the support plate 4 to drive the container cover 7 to rotate and open.

[0033] The driving end of the motor 6 penetrates the inner wall of the support plate 4 and is fixedly connected with a bidirectional threaded rod 16. The left and right sides of the outer wall of the bidirectional threaded rod 16 are threadedly connected with a threaded slide plate 15. The bottom ends of the two threaded slide plates 15 are connected to the inclined rod 5 through a support structure. The support structure includes a rotating inclined plate 17 rotatably connected to the inner wall of the bottom end of the threaded slide plate 15. The bottom ends of the two rotating inclined plates 17 are rotatably connected to the support rod 20. The left and right sides of the front end of the support rod 20 are fixedly connected with a connecting block 19. The opposite end of the connecting block 19 on the left and right sides is connected to the top of the left and right ends of the inclined rod 5. Dynamic connection, the outer wall of the support rod 20 is slidably connected to the inner wall of the support plate 4, the inner wall of the connecting block 19 is slidably connected with the sliding rod 21, the top of the connecting block 19 corresponds to the outer diameter of the sliding rod 21 and is fixedly connected to the second spring 18, the top of the second spring 18 is fixedly connected to the inner wall of the support plate 4, the right end of the bidirectional threaded rod 16 is rotatably connected to the inner wall of the support plate 4, the top of the threaded slide plate 15 is slidably connected to the inner wall of the support plate 4, the outer wall of the connecting block 19 is slidably connected to the inner wall of the support plate 4, and the top and bottom of the sliding rod 21 are fixedly connected to the inner wall of the support plate 4.

[0034] Specifically, the starting motor 6 drives the bidirectional threaded rod 16 to rotate, thereby causing the threaded slide plate 15 to slide to the left and right on the inner wall of the support plate 4, thereby causing the rotating inclined plate 17 to rotate and open, thereby pulling the support rod 20 to slide upward, and causing the connecting block 19 to slide upward along the slide rod 21 to compress the second spring 18, thereby causing the inclined rod 5 to rotate upward on the outer wall of the fixed shaft 14 and tilt toward the front side of the container cover 7, pulling the container cover 7 to rotate and open, thereby realizing the opening of the container cover 7 of the pressure vessel body 1.

[0035] The inner walls of the bottom ends of the two reinforcement blocks 9 are slidably connected with telescopic plug blocks 11 near the container cover 7. Reinforcement slots 13 are provided on the left and right sides of the top of the container cover 7. The shape of the bottom end of the telescopic plug block 11 matches the shape of the reinforcement slot 13. A pull rod 8 is fixedly connected to the middle part of the top end of the telescopic plug block 11. The outer wall of the pull rod 8 is slidably connected to the inner wall of the reinforcement block 9. The top of the pull rod 8 penetrates the outer wall of the reinforcement block 9. The top of the telescopic plug block 11 corresponds to the outer wall of the pull rod 8 and is fixedly connected to the first spring 12.

The opposite ends of the screws 2 on the left and right sides are respectively rotatably connected to the outer walls of the left and right sides of the pressure vessel body 1.

[0036] Specifically, by rotating the screw 2, the pull plate 3 drives the reinforcement block 9 to slide toward the side of the container cover 7, and when sliding to the position of the reinforcement slot 13, the telescopic plug 11 will pop out and get stuck on the inner wall of the reinforcement slot 13 under the action of the first spring 12, thereby completing the secondary reinforcement of the container cover 7.

[0037] Working principle: First, when it is necessary to open the container cover 7 on the top of the pressure vessel body 1, the starting motor 6 drives the bidirectional threaded rod 16 to rotate, so that the threaded slide plate 15 slides to the left and right sides on the inner wall of the support plate 4, so that the rotating inclined plate 17 rotates and opens, thereby pulling the support rod 20 to slide upward, and the connecting block 19 slides upward along the slide rod 21 to compress the second spring 18, so that the inclined rod 5 rotates upward on the outer wall of the fixed shaft 14 and tilts toward the front side of the container cover 7, pulling the container cover 7 to rotate and open, thereby realizing the container cover of the pressure vessel body 1. When opening and closing, the motor 6 is reversed so that the rotating inclined plate 17 pushes the support rod 20 downward to slide downward, thereby causing the inclined rod 5 to tilt and rotate toward the rear side of the container cover 7, thereby pressing down the container cover 7 to close it, and by rotating the screw 2, the pull plate 3 drives the reinforcement block 9 to slide toward one side of the container cover 7, and when sliding to the position of the reinforcement slot 13, the telescopic plug block 11 will pop out and get stuck on the inner wall of the reinforcement slot 13 under the action of the first spring 12, thereby completing the secondary reinforcement of the container cover 7 and improving the safety of opening and closing the container cover 7 of the pressure vessel body 1.
