[0002] In modern architectural design, the entry door as the first line of defense for family safety and privacy, its performance requirements are increasingly diversified, and the sound insulation effect is one of the important indicators to measure the quality of the entry door. However, the existing entry door generally faces the problem of poor sound insulation effect when in use. The traditional entry door is mainly composed of door frame, door panel and lockset and other basic components, and materials such as wood, steel or aluminum alloy are mostly used. These materials have certain structural strength, but there are obvious deficiencies in sound insulation performance.

[0003] In order to improve the sound insulation effect, some entry doors on the market begin to try to add sound insulation materials such as high-density foam, sound insulation cotton or multi-layer composite board inside the door panel. The application of these sound insulation materials improves the sound insulation ability of the entry door to a certain extent and reduces the possibility of sound transmission through the door panel. However, this improvement method does not fundamentally solve the problem of poor sound insulation effect of the entry door.

[0004] Specifically, after the traditional entry door is rotated and closed, although the lockset can ensure the relative fixation between the door panel and the door frame, due to the manufacturing process, installation precision and wear during long-term use, there will still be a certain gap between the door frame and the door panel. These tiny gaps become the "loose ends" of sound transmission, allowing external noise to easily penetrate the entry door and enter the indoor space, seriously affecting the quietness and comfort of the living environment. In view of the problems in the related art, no effective solution has been proposed so far. SUMMARY

[0007] The utility model provides a novel sound insulation house entrance door, including door frame body, the side of door frame body is rotatably installed with house entrance door body through the hinge, and the upper and lower ends of house entrance door body are provided with contraction groove no.

[0008] Further, in order to realize the sealing sound insulation effect of the upper and lower ends of the house entrance door when closing, the sealing transmission mechanism comprises a transmission inclined plate fixedly connected to one side of the adjusting plate no.

[0009] Further, in order to realize the sealing sound insulation effect of the left and right sides of the house entrance door when closing, the two ends of the adjusting plate no.

[0010] Further, in order to realize the extrusion and pushing of the pressure block when the house entrance door is closed, the inner wall of the door frame body is fixedly connected with a blocking plate.

[0011] Further, in order to realize the automatic reset of the pressure block when not being extruded, the two ends of the pressure block are fixedly connected with a telescopic spring, the surface of the house entrance door is provided with a telescopic groove, and the end of the telescopic spring is fixedly connected in the telescopic groove.

[0012] Further, in order to realize the shock absorption when the house entrance door is closed, the surface of the house entrance door is fixedly installed with a shock absorbing rubber pad.

[0013] Further, in order to realize the opening and closing of the house entrance door after being pushed and pulled and rotated conveniently, the surface of the house entrance door is rotatably installed with a push-pull handle.

[0014] The utility model discloses a beneficial effect is: through the in -house door body closing extrusion pressure block, makes sealing transmission mechanism drive adjusting plate no. 1 and adjusting plate no. 2, respectively telescopic sliding to the corresponding positioning groove no. 1 and positioning groove no. 2 on the door frame, and extrude contact with the sealing sound insulation strip in two positioning grooves, and then promote the sealing effect when the in -house door body closes, the novel in -house door can greatly reduce the gap between the door frame and the door board, effectively block the path of sound transmission through the gap, make the in -house door whole sound insulation performance get the remarkable promotion, provide a more quiet, comfortable indoor environment for the dweller.
