The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0026] See also Figure 1-Figure 5 An energy-saving side-flip door with a hydraulic slow-closing device comprises a door seat 1, a door cover 2 is rotatably arranged on the top of the door seat 1, a pair of fixing rods 3 are fixedly connected to the top of the door cover 2, a rotating rod 4 is fixedly connected to one side of the fixing rod 3, a buffer assembly 5 is arranged on the outer side of the rotating rod 4, a mounting seat 6 is bolted to the bottom of the door seat 1, and a handle 7 is fixedly connected to the top of the door cover 2.

[0027] The mounting seat 6 is fixedly connected to one end of the pipeline, and the door cover 2 is rotatably connected to the door seat 1 to open and close the door seat 1. When the door cover 2 is opened and closed, the fixing rod 3 drives the rotating rod 4 to rotate. When the rotating rod 4 rotates, the buffer assembly 5 applies resistance to the rotating rod 4, thereby buffering the opening and closing of the door cover 2, thereby achieving a buffering effect during the entire process of opening and closing the door.

[0028] In the specific implementation process, Figure 3 As shown, the buffer assembly 5 includes a fixed column 51 fixedly arranged on the top of the mounting seat 6, the inner wall of the fixed column 51 is rotatably connected with a gear 52, the inner ring of the gear 52 is fixedly connected to the outer side of the rotating rod 4, a tooth plate 53 is inserted into the inner wall of the fixed column 51, the outer side of the gear 52 is meshed with the teeth on one side of the tooth plate 53, a spring member 54 is provided at the bottom of the tooth plate 53, and a pair of guide blocks 55 are fixedly connected to the side of the tooth plate 53 away from the gear 52, and the outer side of the guide block 55 is slidably connected to the inner wall of the fixed column 51.

[0029] When the door cover 2 is opened or closed, the rotating rod 4 will be driven to rotate, and the rotating rod 4 will drive the internal gear 52 of the fixed column 51 to rotate, so that the tooth plate 53 moves up and down in the fixed column 51, and through a pair of spring parts 54 at the bottom of the tooth plate 53, the spring parts 54 apply tension to the tooth plate 53 when the tooth plate 53 moves up, and the spring parts 54 are compressed when the tooth plate 53 moves down, so that resistance is generated when the tooth plate 53 moves up and down, and the door cover 2 is slow opened and closed through the rotating rod 4 and the fixed rod 3.

[0030] The spring member 54 includes a fixed tube 54a fixedly arranged at the bottom of the fixed column 51, the bottom of the fixed tube 54a is fixedly connected to the first spring 54b, the inner wall of the fixed tube 54a is inserted with a connecting rod 54c, the top of the connecting rod 54c is fixedly connected to the bottom of the tooth plate 53, and the bottom of the connecting rod 54c is fixedly connected to the top of the first spring 54b. The connecting rod 54c slides in the fixed tube 54a to guide and limit the first spring 54b, so that the first spring 54b is not easily deviated during tension and compression, thereby improving the buffering effect on the tooth plate 53.

[0031] A pair of support blocks 8 are fixedly connected to the outside of the mounting seat 6, and both ends of the rotating rod 4 are rotatably connected to the inner wall of the support block 8. The rotating rod 4 is supported by the support block 8, so that the door cover 2 drives the rotating rod 4 to rotate stably in the support block 8.

[0032] The top of the support block 8 is fixedly connected with a fixing block 9 , and the top of the fixing block 9 is fixedly connected with a cylinder 10 .

[0033] A rotating shaft 11 is rotatably arranged on the inner wall of the cylinder 10 , and a steel wire rope 12 is installed and wound around the outer side of the rotating shaft 11 , and one end of the steel wire rope 12 is connected to the handle 7 through a fixing ring.

[0034] Semicircular blocks 13 are fixedly connected at both ends of the rotating shaft 11, a pair of arc-shaped seats 14 are fixedly connected to the inner wall of the cylinder 10, a second spring 15 is fixedly provided on the inner wall of the arc-shaped seat 14, and a connecting block 16 is fixedly connected to one side of the bottom of the semicircular block 13. The outer side of the connecting block 16 is slidably matched with the inner wall of the arc-shaped seat 14, and one side of the connecting block 16 is in close contact with one end of the second spring 15.

[0035] It should be noted that the cylinder 10 is supported and fixed by the fixing block 9, one end of the steel wire rope 12 passes through the cylinder 10 and is wound around the rotating shaft 11, and the other end is connected and fixed to the handle 7. When the door cover 2 is opened, the rotating shaft 11 remains stationary. When the door cover 2 is closed, the rotating shaft 11 will be pulled to rotate by the steel wire rope 12. When the rotating shaft 11 rotates, it drives the two semicircular blocks 13 to rotate in the cylinder 10, and makes the connecting block 16 at the bottom of the semicircular block 13 enter the arc seat 14. At this time, the connecting block 16 squeezes the second spring 15 to compress the second spring 15, so that the semicircular block 13 generates resistance when it rotates, thereby further improving the buffering effect when the door cover 2 is closed, and greatly reducing the impact force when the large flap door is closed.

[0036] When the door cover 2 is in use, the door cover 2 is opened and closed by driving the rotating rod 4 to rotate, and the rotating rod 4 drives the internal gear 52 of the fixed column 51 to rotate, so that the tooth plate 53 moves up and down in the fixed column 51, through a pair of spring members 54 at the bottom of the tooth plate 53, the spring member 54 applies tension to the tooth plate 53 when the tooth plate 53 moves up, and the spring member 54 is compressed when the tooth plate 53 moves down, thereby generating resistance when the tooth plate 53 moves up and down, and the door cover 2 is slowly opened and closed through the rotating rod 4 and the fixed rod 3. At the same time, when the door cover 2 is closed, the rotating shaft 11 is pulled to rotate by the wire rope 12. When the rotating shaft 11 rotates, it drives the two semicircular blocks 13 to rotate in the cylinder 10, and makes the connecting block 16 at the bottom of the semicircular block 13 enter the arc seat 14. At this time, the connecting block 16 squeezes the second spring 15, compresses the second spring 15, and generates resistance when the semicircular block 13 rotates, thereby further improving the buffering effect when the door cover 2 is closed, and greatly reducing the impact force when the large flap door is closed.
