Provided on the middle rail, one edge of the inner rail corresponds to a second rail and is bent inwardly and has a third track, and the inner rail is coated and mounted on the pair of second ball plates; Two parallel tracks are formed between the inner rail and the middle rail, so that the two can still maintain a good supporting effect when pulled out to improve the stability during use.

Description

Multi-track hidden slide structure

This creation belongs to the field of furniture-assisted sliding devices, especially the multi-track hidden slide rail structure applied between the lower part of the drawer and the furniture body, which uses a pair of parallel rails between the outer rail and the middle rail to extend and pull out Its support effect.

Press, common: such as file cabinets, cabinets and tables, etc. In order to make the drawers pull more smoothly, a slide rail group is usually connected between the drawer and the furniture, and the slide rail group has a slidable steel ball or Lubricating elements such as steel columns provide proper lubrication during the process of carrying the drawer and are easy to pull. For the sake of aesthetics, the so-called bottom-loading slide group is also available on the market. It is attached to the bottom of the drawer and connected to the furniture. When the drawer is pulled out, it will not be seen on the two sides of the drawer. Any structure of the rail, so the bottom mounted rail set is also called the hidden slide group.

However, when the hidden slide rail group is pulled out, the weight of the drawer is directly pressed down on the slide rail group, and the structure is usually side-by-side due to the different force direction and the common side-mounted slide rail group. The mounted slide rail group is more sturdy. Therefore, the hidden slide rail group usually has a rectangular shape, so it is obviously different from the side-mounted slide rail group in the shape of a long flat shape, and can withstand heavier vertical weight. Moreover, the rolling element design used is different from the side-mounted rail group, not all of the balls are spherical, but the cylindrical column is used as the main rolling element, by the roller and As the main track surface when moving, there is a large contact area when pulling out When used, the stability of the relative movement of the rail members is improved.

However, the hidden slide rail sets are arranged in pairs, usually installed on the bottom surface near the two sides of the drawer, so that two parallel moving rails are formed and the sliding is assisted by appropriate rolling elements, and the two parallel movements are only performed. The weight of the rail-bearing drawer is such that the design is easy to cause sway or offset during the movement of the rolling element as a supporting and auxiliary sliding, and the rolling elements are caused to be abnormally worn, thereby affecting the overall use effect. Therefore, it is necessary to improve.

In view of this, one of the purposes of the present invention is to provide a multi-track hidden slide rail structure, in which an additional two parallel rails are formed between an inner rail and a middle rail to form a relatively outward pull-out. At the same time, the auxiliary support effect of the side of the original track is increased through the two parallel tracks, and a better covering force can be provided, thereby greatly improving the stability during use, and avoiding the problem of unsmooth sliding when pulled out. Moreover, the inner rail of the present invention is completely covered when the second ball plate is coated to improve the protection effect after assembly.

In order to achieve the above object, a multi-track hidden slide structure of the present invention comprises: an outer rail, an elongated structure having an L-shaped cross section, and one side of the outer rail is mounted on a fixed surface The other side is formed by bending inwardly to form a first track; a first ball plate comprising a first bracket formed in a G shape corresponding to the first track, and on each side of the first bracket a plurality of first rollers are disposed on the first track, so that the first rollers of the top surface, the bottom surface and the second side of the first ball plate are respectively corresponding to the first roller Four sides of the first track; a middle rail, which is a strip-shaped structure corresponding to the first ball plate and having a U-shaped cross section, and the two edges of the middle rail are respectively extended toward the same direction. Two tracks, the middle The rail system is mounted on the first ball plate such that the first rollers of the bottom surface of the first ball plate are correspondingly coupled to the one of the second rails, and the central and the two sides of the middle rail respectively correspond to each other And the first roller on the top surface and the two sides of the first ball plate; a pair of second ball plates, wherein each of the second ball plates comprises a U-shaped portion corresponding to the middle rail a second bracket, and a plurality of second rollers and a plurality of second balls are respectively disposed on each side of each of the second brackets, and the pair of second ball plates are respectively disposed at positions of the front and rear portions of the middle rail, so that The second rollers of the pair of second ball plates respectively correspond to the two side surfaces and the top surface of the middle rail; and an inner rail corresponding to the length of the second ball plate and having a U-shaped cross section a strip-shaped structure, wherein the two edges of the inner rail respectively correspond to a second rail and are bent inwardly to have a third track and a second ball plate corresponding to the second ball plate, and the inner rail is coated Mounted on the pair of second ball plates such that the top surface and the two side surfaces of the inner rail respectively abut the pair of second Such beads and the top side of the second side of the second roller, and the bottom surface of the plate of the second ball such second ball interposed between the second rail and the third rail.
