[0021] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] See also Figures 1 to 4 , the utility model provides a technical solution:

[0023] A heat insulation structure for energy-saving building doors and windows, comprising a door body 1, the door body 1 is fixedly connected to a door frame through a hinge, a sealing assembly 3 is arranged on the inner wall of the door body 1; the sealing assembly 3 comprises a lifting rod 33 slidably arranged on the inner wall of the door body 1, a sealing spring 31 is fixedly installed on the surface of the lifting rod 33, a sealing plate 34 is fixedly installed on the other end of the sealing spring 31, and one end of the sealing plate 34 extends to the lower surface of the door body 1; a driving assembly is also arranged on the inner wall of the door body 1, and the driving assembly is used to drive the sealing plate 34 to abut against the door frame for sealing; the driving assembly comprises a rotating rod 35 rotatably installed on the inner side wall of the door body 1, a transmission gear 310 and a cam 311 are fixedly installed on the outer surface of the rotating rod 35, and the outer surface of the cam 311 is in contact with the surface of the lifting rod 33;

[0024] Specifically, when the cam 311 rotates and contacts the surface of the lifting rod 33, the rotation of the cam 311 will squeeze the lifting rod 33 downward, and the sealing plate 34 will be driven downward by the action of the connecting rod 32, thereby sealing the gap between the door body 1 and the door frame.

[0025] The driving component further includes a telescopic spring 36 fixedly installed on the inner wall of the door body 1. The other end of the telescopic spring 36 is fixedly installed with a moving rack 38. One end of the moving rack 38 away from the telescopic spring 36 extends to the outside of the door body 1. The moving rack 38 is meshed and connected with the transmission gear 310. A limiting rod 37 is slidably installed on the inner wall of the moving rack 38. One end of the limiting rod 37 penetrates through the inside of the telescopic spring 36 and is fixedly connected with the inner wall of the door body 1. One end of the moving rack 38 away from the telescopic spring 36 is fixedly installed with a pressing rod 39. One end of the pressing rod 39 extends to the outside of the door body 1.

[0026] Specifically, the door body 1 is fixedly connected to the door frame through a hinge. During the closing process of the door body 1, the pressing rod 39 will be pressed. At this time, the pressing rod 39 will move into the door body 1, thereby driving the moving rack 38 to move on the outer surface of the limiting rod 37. Since the moving rack 38 is meshed and connected with the transmission gear 310, the transmission gear 310 will drive the rotating rod 35 to rotate, thereby driving the cam 311 to rotate.

[0027] A heat insulation board 4 is fixedly installed on the inner wall of the door body 1. During the use of the door body 1, the heat insulation board 4 will block the external temperature.

[0028] Handles 2 are fixedly installed on both side walls of the door body 1.

[0029] A connecting rod 32 is installed between the lifting rod 33 and the sealing plate 34. One end of the connecting rod 32 is fixedly connected to the lifting rod 33, and the other end of the connecting rod 32 is fixedly connected to the sealing plate 34. The sealing spring 31 is sleeved outside the connecting rod 32.

[0030] The working principle of the above heat insulation and heat preservation structure for energy-saving building doors and windows is as follows:

[0031] The door body 1 is fixedly connected to the door frame through a hinge. During the closing process of the door body 1, the pressing rod 39 will be pressed. At this time, the pressing rod 39 will move into the door body 1, thereby driving the moving rack 38 to move on the outer surface of the limiting rod 37. Since the moving rack 38 is meshed and connected with the transmission gear 310, the transmission gear 310 will drive the rotating rod 35 to rotate, thereby driving the cam 311 to rotate. As the cam 311 rotates, the lifting rod 33 will be pressed downward. Under the action of the connecting rod 32, the sealing plate 34 will be driven to move downward, thereby sealing the gap between the door body 1 and the door frame. During the use of the door body 1, the heat insulation board 4 will block the external temperature.

[0032] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
