The term "and / or" used herein includes any and all combinations of one or more related listed items.
[0030] See also Figure 1-Figure 6 , which is a schematic diagram of a sliding structure of a hidden drawer rail provided in one embodiment of the utility model, wherein the sliding structure of the hidden drawer rail includes a slide rail assembly 100 and a sliding assembly 200, wherein:
[0031] In order to avoid the guide rail and roller falling off due to too small contact area, the present technical solution proposes a method of using double guide rails to replace the traditional guide rail and roller assembly. The slide rail assembly 100 includes a fixed rail 110 on the cabinet and a sliding rail 120 arranged at the bottom of the drawer. The fixed rail 110 and the sliding rail 120 proposed in this embodiment are both C-shaped guide rails, and the fixed rail 110 and the sliding rail 120 are mutually clamped to increase the connection stability between the drawer and the cabinet.
[0032] In order to support the fixed rail 110 and the sliding rail 120 and provide a rolling effect, a sliding assembly 200 is provided between the fixed rail 110 and the sliding rail 120. The sliding assembly 200 is provided in the gap between the fixed rail 110 and the sliding rail 120, and the shape of the sliding assembly 200 is configured to be similar to the shape of the gap between the fixed rail 110 and the sliding rail 120 for separation and to increase the contact area, so that while achieving a supporting effect, a rolling effect is also provided through a plurality of rollers provided thereon.
[0033] Furthermore, the sliding assembly 200 includes a support body 210, a first type roller 220 and a second type roller 230 provided on the support body 210. The rolling directions of the first type roller 220 and the second type roller 230 are perpendicular to each other. The first type roller 220 and the second type roller 230 are distinguished by their rolling modes. The rolling direction of the first type roller 220 is the up-down direction, and the rolling direction of the second type roller 230 is the left-right direction. Both sides of the first type roller 220 and the second type roller 230 are respectively against the fixed rail 110 and the sliding rail 120 to provide rolling action for the fixed rail 110 and the sliding rail 120, reduce friction, and avoid wear between the fixed rail 110 and the sliding rail 120.
[0034] Furthermore, the bracket body 210 includes a first bracket 211, a second bracket 212 and a third bracket 213 respectively arranged on both sides of the first bracket 211. In the present embodiment, the second bracket 212 and the third bracket 213 are both L-shaped brackets, one end of the second bracket 212 is connected to the side of the first bracket 211, and it is arranged parallel to the first bracket 211, so that the roller arranged on the second bracket 212 can be attached to the end surface of the fixed rail 110 and the sliding rail 120. One end of the third bracket 213 is connected to the other side of the first bracket 211, and is arranged perpendicular to the second bracket 212 and the first bracket 211, and a gap for accommodating the fixed rail 110 is provided between the second bracket 212 and the third bracket 213. It is worth noting that the first bracket 211, the second bracket 212 and the third bracket 213 together enclose a through passage for accommodating the fixed rail 110.
[0035] In order to provide rollers on the first bracket 211, the second bracket 212 and the third bracket 213, the first bracket 211 and the third bracket 213 are provided with a plurality of first rolling grooves 214 for accommodating the first type rollers 220 along their length direction, and the second bracket 212 is provided with a plurality of second rolling grooves 215 for accommodating the second type rollers 230 along its length direction. The first type rollers 220 are embedded in the first rolling grooves 214 to abut against the inner periphery of the sliding rail 120 and the outer periphery of the fixed rail 110; the second type rollers 230 are embedded in the second rolling grooves 215 to abut against the inner periphery of the sliding rail 120 and the outer periphery of the fixed rail 110. The first type rollers 220 and the second type rollers 230 provide rolling action to the fixed rail 110 and the sliding rail 120 while supporting the fixed rail 110 and the sliding rail 120. It is worth emphasizing that the second rolling grooves 215 are respectively provided at both ends of the second bracket 212 to support the sliding rail 120 and prevent it from directly contacting the fixed rail 110. In order to support the sliding length of the sliding rail 120, in this embodiment, the length of the first bracket 211 is greater than the length of the second bracket 212 and the third bracket 213 to ensure that even if the sliding rail 120 slides a certain distance, it will not directly rub against the fixed rail 110, thereby extending the service life of the sliding structure.
[0036] It is worth emphasizing that in order to prevent the sliding rail 120 and the fixed rail 110 from falling off during use, a first stopper 111 extends from one end of the fixed rail 110 close to the drawer's outward sliding direction. The projection of the first stopper 111 along the length direction of the fixed rail is mapped to the end surface of the third bracket 213 to prevent the sliding assembly 200 from falling directly from between the fixed rail 110 and the sliding rail 120 during use of the drawer.
[0037] Similarly, the second stopper 121 and the third stopper 122 extend from one side of the sliding rail toward the third bracket 213, and the third bracket 213 is disposed between the second stopper 121 and the third stopper 122. When the third bracket 213 abuts against the first stopper 111, the sliding rail 120 slides forward again until the second stopper 121 abuts against the end surface of the third bracket 213, and the sliding rail 120 cannot move forward any further, and the drawer is pulled out to the maximum length. Due to the effect of the first stopper 111 disposed on the fixed rail 110, the sliding assembly 200 cannot fall off from the fixed rail 110, and the second stopper 121 and the third stopper 122 also ensure that the sliding rail 120 cannot fall off from the sliding assembly 200, thereby improving the stability of the sliding structure.
[0038] In summary, according to a sliding structure of a hidden rail of a drawer provided by the utility model, by using a fixed rail and a sliding rail to replace the traditional sliding rail and roller structure, the stability between the cabinet and the drawer is enhanced, and a sliding assembly is provided between the fixed rail and the sliding rail, which is used to respectively abut against the outside of the fixed rail and the inside of the sliding rail, and provide support and rolling effects. Specifically, the sliding rail assembly includes a fixed rail provided on the cabinet, and a sliding rail provided at the bottom of the drawer. The fixed rail and the sliding rail are mutually interpenetrated, which enhances the contact area and the degree of engagement between the two, and ensures the stability of the structure. A sliding assembly is also provided between the fixed rail and the sliding rail to separate the fixed rail and the sliding rail. The outside of the sliding assembly abuts against the inner side of the sliding rail, and the fixed rail is inserted into the interior of the sliding assembly. While supporting the fixed rail and the sliding rail, the roller also provides a rolling effect for the sliding rail, further ensuring that the drawer can be pulled out along the length direction of the sliding rail.
