4. The sliding element acts on the sliding part through the guiding part, and can partially counteract the elastic force of the pressing elastic piece acting on the pushing element, so that a user can use less pressing force to realize automatic opening of the movable sliding rail, and user experience is effectively improved.
5. The swinging piece can effectively and forcedly restrict the sliding part to slide along the track of the heart-shaped sliding groove along a sequence direction through the elastic swinging piece or the elastic swinging part to elastically swing on the pushing element, so that the problems that the swinging piece is blocked on the pushing element, cannot swing on the pushing element or cannot slide along the track of the heart-shaped sliding groove due to the fact that the swinging piece is easy to randomly displace on the pushing element in the transportation or use process because the swinging piece cannot be positioned on the pushing element in the prior art are avoided, and the opening and closing process between the movable piece and the immovable piece of furniture is more stable and smooth.
6. The movable sliding rail is provided with a poking part, the fixed sliding rail is provided with a damping device, a certain closing stroke is formed between the movable sliding rail and the fixed sliding rail when the pressing rebound device is reset to the initial terminal position, and the movable sliding rail is continuously closed, the movable sliding rail acts through the poking part and drives the damping device to compress and generate damping force, and the movable sliding rail can automatically slide and close on the fixed sliding rail, so that the problems that the service life of a product is short and the use experience of furniture is influenced due to the closing of the movable sliding rail are avoided, and meanwhile, the closing acting force of a user on the movable sliding rail can be further reduced.
Comprehensively, the novel sliding door has the characteristics of simple and reasonable structure, reliable performance, compact connection among all components, long service life, low manufacturing cost, quick and convenient disassembly and assembly, high flexibility and the like, has strong practicability, and can be widely applied to furniture products such as furniture drawers, furniture sliding doors and the like, and the application range.
