Description

Technical Field

[0001] This utility model relates to the field of door leaf technology, specifically to a lap joint structure between door leaves. Background Technology

[0002] Door panels are an important component of doors, typically consisting of a door frame and a core panel (door panel). They function to close off passageways and divide spaces. Door panels are made of various materials, including solid wood and bamboo plywood. Different materials have different characteristics and applicable scenarios. For example, bamboo plywood door panels have advantages such as being environmentally friendly, durable, moisture-proof, and fire-resistant, making them suitable for various occasions such as residential communities, commercial offices, hospitals, and schools.

[0003] When the door panels are closed, there are gaps between them. To ensure a good seal between the panels, some panels are fitted with gap-covering panels to cover the gaps. However, these panels sometimes fail to adhere tightly to the panel surface at the gaps, resulting in an inadequate seal. Therefore, we propose an overlapping joint structure between the door panels. Utility Model Content

[0004] The purpose of this utility model is to provide a stop overlap structure between door panels. Vertical grooves and abutment grooves are respectively provided on the surfaces of the aligned left and right door panels. A rubber strip is connected to the vertical groove by an elastic rubber sheet. When the left and right door panels are aligned and closed, the first magnet on the side of the abutment groove and the second magnet in the rubber strip attract each other, so that the rubber strip is attracted and pressed tightly against the inner surface of the abutment groove, achieving a good sealing effect and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a door leaf overlap structure, including a left door panel and a right door panel, the sides of the left door panel and the right door panel are aligned with each other; the surfaces of the aligned surfaces of the left door panel and the right door panel are respectively provided with vertical grooves and abutment grooves, the vertical grooves and abutment grooves are aligned, a vertical rubber strip is connected in the vertical groove by an elastic rubber sheet, a first magnet is vertically embedded and fixed in the right door panel on the side of the abutment groove, a second magnet is vertically embedded and fixed in the rubber strip, the first magnet and the second magnet attract each other so that the rubber strip is pressed tightly against the surface of the abutment groove.

[0006] By adopting the above technical solution, when the left and right door panels are aligned and the door is closed, the first and second magnets attract each other, which straightens the elastic rubber sheet and causes the rubber strip to abut against and adhere to the inner surface of the groove, achieving a good sealing effect and improving the sealing performance of the door.

[0007] Optionally, the rear end of the abutment groove is provided with an extension groove, the extension groove having the same depth as the abutment groove.

[0008] By adopting the above technical solution, when the right door panel is pulled forward to open, the rubber strip can first slide backward in the extension groove, so as to avoid the rubber strip getting stuck in the abutment groove and preventing the right door panel from opening.

[0009] Optionally, the rear end of the extension groove transitions to the side surface of the right door panel via an inclined ramp.

[0010] Optionally, a seam-covering plate is provided on the rear side of the left door panel, and a plate groove is provided on the rear side surface of the right door panel. When the left and right door panels are aligned, the seam-covering plate is in contact with the inner surface of the plate groove.

[0011] By adopting the above technical solution, after the left and right door panels are aligned, the seam cover is placed in the panel groove to cover the seam.

[0012] Optionally, a rubber pad is attached to the front surface of the gap-sealing plate, and the gap-sealing plate is in contact with the surface of the plate groove through the rubber pad.

[0013] By adopting the above technical solution, the rubber pad can provide a certain sealing effect for the gap-sealing plate.

[0014] Optionally, when the seam cover is placed in the groove, the rear surface of the seam cover is flush with the rear surface of the right door panel.

[0015] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0016] 1. The technical solution of this application provides vertical grooves and abutment grooves on the surfaces of the aligned left and right door panels respectively. A rubber strip is connected in the vertical groove by an elastic rubber sheet. When the left and right door panels are aligned and closed, the first magnet on the side of the abutment groove and the second magnet in the rubber strip attract each other, so that the rubber strip is attracted and sticks tightly against the inner surface of the abutment groove, achieving a good sealing effect.

[0017] 2. The technical solution of this application provides an extension groove extending backward at the rear end of the abutment groove. When the right door panel is pulled forward to open, the rubber strip can slide backward in the extension groove until the rubber strip is no longer magnetically attracted and retracts into the vertical groove, thus avoiding the rubber strip getting stuck in the abutment groove and preventing the right door panel from opening.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a door leaf overlap structure, including a left door panel 1 and a right door panel 2. When in use, the left door panel 1 and the right door panel 2 are installed on the left and right sides of the door leaf frame. When the sides of the left door panel 1 and the right door panel 2 are aligned with each other, the door leaf is in a closed state. If necessary, locks can also be installed on the left door panel 1 and the right door panel 2.

[0025] Similar to existing technologies, the left door panel 1 has a seam cover 11 on its rear side and the right door panel 2 has a groove 21 on its rear side surface. When the left door panel 1 and the right door panel 2 are aligned and closed, due to the presence of the seam cover 11, the left door panel 1 must be closed first and then the right door panel 2. The seam cover 11 will be in contact with the inner surface of the groove 21, and a rubber pad 111 is attached and fixed to the front surface of the seam cover 11, so that the seam cover 11 is in contact with the surface of the groove 21 through the rubber pad 111, which can have a certain sealing effect. At this time, when the seam cover 11 is placed in the groove 21, the rear surface of the seam cover 11 is flush with the rear surface of the right door panel 2.

[0026] Since it is impossible to guarantee that the seam cover 11 is tightly sealed in the groove 21, in order to improve the sealing effect, vertical grooves 12 and abutment grooves 22 are respectively provided on the surfaces of the aligned surfaces of the left door panel 1 and the right door panel 2. A vertical rubber strip 3 is connected to the vertical groove 12 through an elastic rubber sheet 32. A first magnet 24 is vertically embedded and fixed in the right door panel 2 on the side of the abutment groove 22, and a second magnet 31 is vertically embedded and fixed in the rubber strip 3.

[0027] When the left door panel 1 and the right door panel 2 are aligned and the door is closed, the vertical groove 12 and the abutment groove 22 will align with each other, thereby causing the first magnet 24 and the second magnet 31 to attract each other and make the rubber strip 3 stick tightly to the surface of the abutment groove 22, providing a good sealing effect.

[0028] An extension groove 23 is also provided at the rear end of the abutment groove 22. The extension groove 23 has the same depth as the abutment groove 22, and the rear end of the extension groove 23 transitions to the side surface of the right door panel 2 through an inclined slope. When it is necessary to open, due to the presence of the seam cover 11, the right door panel 2 needs to be opened first, so that the right door panel 2 is pulled to the front end. The rubber strip 3 will slide to the rear end in the extension groove 23 until the first magnet 24 and the second magnet 31 are misaligned and can no longer be attracted. Under the pulling and resetting action of the elastic rubber sheet 32, the rubber strip 3 is pulled back and placed in the vertical groove 12. This can prevent the rubber strip 3 from getting stuck in the abutment groove 22 and preventing the right door panel 2 from opening when it is opened.

[0029] In use, the left door panel 1 must be closed first, and then the right door panel 2 can be closed. After closing, the right side of the left door panel 1 and the left side of the right door panel 2 are aligned, thereby aligning the vertical groove 12 with the abutment groove 22. Under the mutual attraction of the first magnet 24 and the second magnet 31, the rubber strip 3 is attracted and adhered to the surface of the abutment groove 22, and the elastic rubber sheet 32 ​​is straightened. The rubber strip 3 and the elastic rubber sheet 32 ​​work together to seal the area. The gap cover 11 also abuts against the surface of the plate groove 21 through the rubber pad 111, which also has a certain sealing effect, giving the door a good sealing effect. When it is necessary to open, the right door panel 2 is opened first and pulled to the front. The rubber strip 3 will slide to the rear end in the extension groove 23 until the first magnet 24 and the second magnet 31 are misaligned and can no longer attract. Under the pulling and resetting action of the elastic rubber sheet 32, the rubber strip 3 is pulled back and placed in the vertical groove 12.
