Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] See Figures 1 to 4 The dual-cylinder controlled opening structure of this embodiment includes a cylinder 10, an opening and closing mechanism 20 for quick opening is provided at the opening of the cylinder 10, and an adjustment mechanism 30 for improving sealing ability is provided at the top of the opening and closing mechanism 20.

[0026] The opening and closing mechanism 20 includes a mounting plate 201 fixedly connected to the top of the cylinder 10. The mounting plate 201 is symmetrically rotatably connected to two sides of the rotating shaft 202. Each rotating shaft 202 is symmetrically fixedly connected to two ends of an L-shaped rod 203. The end of the L-shaped rod 203 away from the rotating shaft 202 is fixedly connected to a top cover 204 for sealing the opening at the top of the cylinder 10.

[0027] The opening and closing mechanism 20 also includes a lever 205 fixedly connected to the rotating shaft 202. A cylinder body 206 is fixedly connected to the bottom of the mounting plate 201. The output end of the cylinder body 206 is rotatably connected to the end of the lever 205 away from the rotating shaft 202.

[0028] The top cover 204 is semi-circular, and a rubber sealing gasket is installed at the bottom of each top cover 204.

[0029] In specific operation, when closing the opening of the cylinder 10, the output end of the cylinder body 206 moves outward. During this movement, the output end of the cylinder body 206 drives the rotating shaft 202 to rotate via the lever 205. During this rotation, the rotating shaft 202 drives the top cover 204 to move to the opening of the cylinder 10 via the L-shaped rod 203, thus closing the opening of the cylinder 10 using the two semi-circular top covers 204. When opening the opening of the cylinder 10, during the retraction movement of the output end of the cylinder body 206, the rotating shaft 202 rotates via the lever 205. During rotation, the L-shaped rod 203 drives the top cover 204 to detach from the opening of the cylinder 10. The opening of the cylinder 10 is opened by the two semi-circular top covers 204 moving away from each other. The lever 205 and the rotating shaft 202 are driven synchronously by the dual cylinders, which drive the L-shaped rod 203 to rotate, thereby controlling the automatic opening and closing of the two semi-circular top covers 204. This replaces the traditional bolt fixing or manual disassembly method, making the operation simple, time-saving and labor-saving, greatly improving the maintenance efficiency of the equipment, reducing human error, and improving the safety of use.

[0030] The adjustment mechanism 30 includes a housing 301 fixedly connected to the top of one of the top covers 204. A round tube 314 is fixedly connected to the top of the housing 301. A push rod 302 is slidably connected to the top of the round tube 314. A first spring 304 is slidably sleeved on the outside of the push rod 302, and the first spring 304 is located outside the round tube 314. A plurality of vent holes 313 are opened on the side of the round tube 314.

[0031] The adjustment mechanism 30 also includes a first connecting rod 305 rotatably connected to the inner wall of the housing 301. One end of the first connecting rod 305 is rotatably connected to a first sealing plate 303, and the first sealing plate 303 abuts against the bottom of the housing 301.

[0032] The first connecting rod 305 is rotatably connected to a connecting rod 308 at the end away from the sealing plate. The connecting rod 308 is rotatably connected to a second connecting rod 306 at the end away from the first connecting rod 305. The middle part of the second connecting rod 306 is rotatably connected to the inner wall of the outer casing 301. The second connecting rod 306 is rotatably connected to a third connecting rod 307 at the end away from the connecting rod 308. The third connecting rod 307 is rotatably connected to a second sealing plate 309 at the end away from the second connecting rod 306.

[0033] The second sealing plate 309 is symmetrically provided with slide rods 310 on the top. Each slide rod 310 is slidably connected to a horizontal plate 311 on the outside. One end of each horizontal plate 311 is fixedly connected to the side wall of the outer shell 301.

[0034] A second spring 312 is sleeved on the outside of the slide bar 310. One end of the second spring 312 is fixedly connected to the top of the horizontal plate 311, and the other end of the second spring 312 is fixedly connected to the top protrusion of the slide bar 310.

[0035] In actual operation, the second spring 312 pushes the second sealing plate 309 downward to block the through hole between the outer shell 301 and the top cover 204. At the same time, the first connecting rod 305, the second connecting rod 306 and the third connecting rod 307 drive the first sealing plate 303 to block the bottom of the circular tube 314. The first sealing plate 303 and the second sealing plate 309 enhance the airtightness of the inside of the cylinder 10. With the second spring 312 providing elastic pre-tightening force, active pressure sealing and error compensation can be achieved after closing, ensuring uniform and durable sealing.

[0036] When it is necessary to release the internal pressure of the cylinder 10, press down on the push rod 302. The push rod 302 will push down to disengage the first sealing plate 303 from the bottom of the round tube 314. At the same time, the first sealing plate 303 will drive the second sealing plate 309 to disengage from the bottom of the outer shell 301 through the first connecting rod 305, the second connecting rod 306 and the third connecting rod 307, so as to realize the interconnection between the cylinder 10 and the outside and balance the internal and external pressure.

[0037] Working principle:

[0038] When closing the opening of the cylinder 10, the output end of the cylinder body 206 moves outward. During this movement, the output end of the cylinder body 206 drives the rotating shaft 202 to rotate via the lever 205. As the rotating shaft 202 rotates, it drives the top cover 204 to move to the opening of the cylinder 10 via the L-shaped rod 203, thus closing the opening of the cylinder 10 with the two semi-circular top covers 204. When opening the opening of the cylinder 10, the output end of the cylinder body 206 retracts and moves, driving the rotating shaft 202 to rotate via the lever 205. As the rotating shaft 202 rotates, it drives the top cover 204 to move outward from the opening of the cylinder 10 via the L-shaped rod 203. The opening of the cylinder 10 is achieved by separating the two semi-circular top covers 204 from each other. The second sealing plate 309 is pushed downward by the second spring 312 to block the through hole between the outer shell 301 and the top cover 204. At the same time, the first sealing plate 303 is driven by the first connecting rod 305, the second connecting rod 306 and the third connecting rod 307 to block the bottom of the circular tube 314. The first sealing plate 303 and the second sealing plate 309 enhance the airtightness of the cylinder 10. With the second spring 312 providing elastic pre-tightening force, active pressure sealing and error compensation can be achieved after closing, ensuring uniform and long-lasting sealing.

[0039] When it is necessary to release the internal pressure of the cylinder 10, press down on the push rod 302. The push rod 302 will push down to disengage the first sealing plate 303 from the bottom of the round tube 314. At the same time, the first sealing plate 303 will drive the second sealing plate 309 to disengage from the bottom of the outer shell 301 through the first connecting rod 305, the second connecting rod 306 and the third connecting rod 307, so as to realize the interconnection between the cylinder 10 and the outside and balance the internal and external pressure.

[0040] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
