[0016] Figure 1 This is an isometric view of the present invention;

[0017] Figure 2 This is a partial sectional view of the present invention.

[0018] In the diagram: 1 Door leaf one, 2 Door leaf two, 3 Wall, 4 Hinges, 5 Sealing plate, 6 Diaphragm, 7 Guide groove, 8 Chamber, 9 Cover plate, 10 Shaft, 11 Scroll spring box, 51 Plate, 52 Semi-circular protrusion, 53 Semi-circular groove. Detailed Implementation

[0019] This utility model embodiment provides a folding door gap sealing plate, such as Figure 1-2 As shown, it includes door leaf 1 and door leaf 2, which are connected by hinge 4. The other end of door leaf 1 or door leaf 2 is hinged to the wall 3.

[0020] A sealing plate 5 is provided on one side of door leaf 1 and door leaf 2 respectively. The sealing plate 5 includes a plate body 51 and a sealing structure provided on the plate body 51. The sealing structures can be interlocked.

[0021] like Figure 2 As shown, the sealing structure consists of a semi-circular protrusion 52 and a semi-circular groove 53, which are respectively disposed on both sides of the plate 51. The semi-circular protrusion 52 and semi-circular groove 53 on door leaf 1 cooperate with the semi-circular groove 53 and semi-circular protrusion 52 on door leaf 2. The diameter of the semi-circular protrusion 52 is slightly larger than that of the semi-circular groove 53.

[0022] When door leaf 1 and door leaf 2 are closed, the semi-circular protrusion 52 on door leaf 1 is inserted into the semi-circular groove 53 on door leaf 2, and the semi-circular protrusion 52 on door leaf 2 is inserted into the semi-circular groove 53 on door leaf 1. The two fit together to block the gap between door leaf 1 and door leaf 2, thus improving the sound insulation effect of the folding door.

[0023] The sealing plate 5 can be made of rubber strips, silicone sealing strips, or polyurethane foam. The specific material is not limited.

[0024] like Figure 1 As shown, in order to prevent hands from being pinched during the use of the folding door and to further improve the sound insulation effect of the folding door, a diaphragm 6 is also installed in the gap between door leaf 1 and door leaf 2. A telescopic component is installed in both door leaf 1 and door leaf 2. The two telescopic components are respectively connected to the two ends of the diaphragm 6. The telescopic components can retract and extend the diaphragm 6.

[0025] like Figure 2 As shown, the telescopic assembly includes a rotating shaft 10 and a spiral spring box 11. Door leaf 1 and door leaf 2 have chambers 8 for housing the rotating shaft 10, which is pivotally connected within the chambers 8. The spiral spring box 11 includes a housing with a scroll pivotally connected inside. A spiral spring is wound on the scroll. The spiral spring box 11 is existing technology and is consistent with a spring-loaded structure. The central scroll of the spiral spring box 11 is coaxially connected to the rotating shaft 10, and the two ends of the diaphragm 6 are wound onto the two rotating shafts 10 respectively. Corresponding sides of door leaf 1 and door leaf 2 have guide grooves 7 for the diaphragm 6 to enter and exit.

[0026] When one of the door panels is opened, it will pull the diaphragm 6. During the process of pulling out the diaphragm 6, the pivot 10 and the spiral spring will be wound and tightened. The diaphragm 6 covers the door gap between door panel 1 and door panel 2. On the one hand, it can prevent hands from being caught in the door gap, and on the other hand, it can improve the sound insulation effect when the door is opened.

[0027] Both door leaf 1 and door leaf 2 are equipped with removable cover plates 9 at corresponding chambers 8. The cover plates 9 are connected by snap-fit ​​or bolts.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
