[0002] In home decoration, many families will choose to use wood floors to decorate the living room, and use waterproof ceramic floor tiles to decorate the balcony. The connecting part between the indoor and the balcony is usually provided with a threshold stone to transition and connect the indoor and the balcony. The connecting structure of the wood floor and the balcony threshold stone mainly ensures the smooth transition between the floor and the threshold stone.

[0003] For example, a wood floor and balcony threshold stone connecting structure is disclosed in Chinese Patent (Publication No. CN219080854U), which comprises a pressing plate, a compression spring for controlling the expansion joint of the wood floor, and a limiting plate fixed at one end of the compression spring. The pressing plate is arc-shaped in cross section, and a clamping strip with an arc-shaped cross section is arranged along the length direction of the pressing plate and connected to the inner concave surface of the pressing plate. A base is further provided, and the base is provided with a clamping groove for matching the clamping strip. The pressing plate can rotate in the clamping groove through the clamping strip, so that the pressing plate can adapt to the connection between the wood floor and the balcony threshold stone with different heights, and the problem that the pressing plate of the wood floor with a compression spring in the prior art can only be used for the transition and connection between adjacent wood floors but cannot be used for the connection between wood floors with different materials and different heights and the balcony threshold stone is solved, and the wood floor and balcony threshold stone connecting structure has strong popularization and application value.

[0004] However, the above-mentioned search patent still has some shortcomings. The spring and the limiting plate can adapt to the expansion of the wood floor in the horizontal plane and extend left and right, but cannot adapt to the extension up and down in the vertical plane, so that when the wood floor expands upward, the pressing plate will deform and affect its appearance, which is not convenient to use. Therefore, a wood floor and balcony threshold stone connecting structure is proposed. Content of the utility model

When the wooden floor expands due to water absorption, the limiting plate 603 is pushed horizontally to compress the second spring 602. The second spring 602 is compressed to adapt to the expansion of the wooden floor in the horizontal plane. At the same time, the wooden floor pushes the pressing plate strip 5 to move upwards, so that the pressing plate strip 5 drives the installation bin 4 to move upwards, and the installation bin 4 drives the installation plate 3 to move upwards together with the guide block 604 and the guide groove 605 to stretch the first spring 601. The first spring 601 is stretched to adapt to the expansion of the wooden floor in the vertical plane.
