Detailed Implementation
[0028] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only a part of the embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments in this solution without creative effort are within the protection scope of this solution.
[0029] like Figures 1 to 8 As shown in the figure, this embodiment designs a slider-type multi-linkage sliding door structure, including a door frame and multiple door panels.
[0030] The door frame comprises several separate components, including side door frames 1, track frames 3, and channel rails 7. Channel rails 7 are positioned above the door leaf, and track frames 3 are positioned below the door leaf. The two ends of track frames 3 connect to the lower ends of the two side door frames 1; the upper end of channel rails 7 connects to the upper ends of the two side door frames 1; and a strip track 4 is mounted on track frames 3. Channel rails 7 contain multiple T-shaped track grooves 71. Track frames 3 have mounting slots into which the strip track 4 is fitted. The ends of the strip track 4 are equipped with end pads 5 and supplementary pads 15, which extend the strip track 4 and fill the mounting slots, while also facilitating the disassembly of the strip track 4. Side door frames 1 are fitted with buffer strips 2 to cushion the impact of the door leaf; corner brackets 18 are provided at the connection between the side door frames 1 and channel rails 7; and a U-shaped sleeve 6 covers the outer side of the channel rail 7. The number of T-shaped track grooves 71, the number of door panels, and the number of strip tracks 4 are the same.
[0031] The door panel comprises multiple separate components, including glass 16, side frames 8, lower frame 9, and upper frame 10. Glass 16 can be replaced with wood, acrylic, or other plate-like structures. When glass 16 is used, its upper edge engages with the upper frame 10, its left and right edges engage with different side frames 8, and its lower edge engages with the lower frame 9. A track wheel 13 is embedded in the lower part of the lower frame 9.
[0032] Track sliders 14 are installed at both ends of the upper frame 10 of the door leaf, and the track sliders 14 slide in engagement with the T-shaped track groove 71. Track wheels 13 are installed on the lower frame 9 of the door leaf, and the track wheels 13 are placed on the strip track 4 and slide along the strip track 4. The structure of the groove track 7 and the track sliders 14 in cooperation can effectively reduce the wobbling gap of the door leaf during the sliding process and improve the stability of the door leaf during the push-pull opening and closing process. Lateral slots 141 are provided on opposite sides in the width direction of the track sliders 14. The lateral slots 141 and the groove edges of the T-shaped track groove 71 interlock with each other, thereby preventing the track sliders 14 from falling down out of the T-shaped track groove 71.
[0033] Limiting stops 17 are installed on the track sliders 14 of some door panels, with the limiting stops 17 protruding laterally from the track sliders 14. Limiting wheels 12 are installed at the ends of the upper frame 10 of adjacent door panels. When the limiting wheels 12 abut against the limiting stops 17, the two adjacent door panels are limited. Mounting grooves 142 are provided on opposite sides of the track sliders 14 along their length. The limiting stops 17 are L-shaped, with their lateral portions inserted into the mounting grooves 142. The vertical portions of the limiting stops 17 protrude from the track sliders 14.
[0034] When the sliding door structure is a three-section sliding door structure, the track 7 has three parallel T-shaped track grooves 71, arranged from the inside out, and running in a left-right direction; the number of door panels and the number of strip tracks 4 are three; the three door panels are the outer door panel, the middle door panel, and the inner door panel, with the middle door panel located between the outer and inner door panels. This allows the sliding door structure to effectively solve the problem of overlapping of the three doors when they move left and right when applied to a shower room.
[0035] A limit stop 17 is installed on the right end of the track slider 14 of the outer door leaf. The limit stop 17 is located at the right end of the track slider 14 and protrudes inward. A limit stop 17 is installed on the left end of the track slider 14 of the inner door leaf. The limit stop 17 is located at the left end of the track slider 14 and protrudes outward. Limit wheels 12 are installed at both ends of the upper frame 10 of the middle door leaf. Through the limit stop 17 and the limit wheels 12, the linkage between the inner door leaf, the outer door leaf, and the middle door leaf can be realized, improving the convenience of use.
[0036] Each door leaf has an inverted T-shaped plug-in linkage 19 fixed above its upper frame 10. A slotted transmission plate 11 has holes that mate with the plug-in linkage 19. The upper end of the plug-in linkage 19 engages with the slotted transmission plate 11, allowing the slotted transmission plate 11 to move vertically relative to the upper frame 10 and to move horizontally with the door leaf. The lower part of the track slider 14 and / or the bracket of the limiting wheel 12 are installed within the slotted transmission plate 11. During door leaf installation, the plug-in linkage 19 at the upper end of the door leaf is simply inserted into the corresponding hole on the slotted transmission plate 11, simplifying the installation process. Because the slotted transmission plate 11 can move vertically relative to the upper frame 10, minor adjustments or deformations in the door frame height do not affect the normal opening and closing of the door leaf, improving the compatibility and tolerance between the sliding door and the door frame. Adjusting the door frame height does not affect the fit with the door leaf, eliminating the need for adjusting the door leaf's buffer height.
[0037] The above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation; it is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom remain within the scope of this technology.
