Description

Concealed rail gap adjusting device

This creation belongs to the field of auxiliary sliding devices for furniture, and more particularly to a hidden rail gap adjusting device applied to cabinet drawers, which can be quickly disassembled and adjusted for gaps.

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, there must be a certain tolerance between the drawer and the furniture for assembly. When installing, assembling or producing manually, it is more or less because the tolerance is too large, causing the drawer and the furniture to be horizontal or vertical. There are some gaps in the direction, even between the hidden slide rail and the bottom surface of the drawer, which not only affects the overall aesthetics, but also causes uneven displacement of the hidden slide rail due to the non-center position of the drawer. , and thus damage its original function, and may even cause the drawer to open smoothly. At present, there are various devices or structures for adjusting the gap on the market, such as: Republic of China Invention Patent No. M448201 "No-section pumping "Drawer panel adjustment device", Chinese Patent No. I404868 "Auxiliary positioning device for slide rail assembly", "DEVICE FOR FIXING A DRAWER EXTENSION MECHANISM", U.S. Patent No. 5,580,139, "CLOSING DEVICE FOR", U.S. Patent No. 7,533,946 "DRAWER", U.S. Patent No. 5,730,514, "SHOCK ABSORBING LOCKING DISCONNECT LATCH FOR BALL BEARING SLIDES", U.S. Patent Publication No. 20050231083 "UNDERMOUNT DRAWER SLIDE", PCT Patent Publication No. WO 2004/110213 "FRONT LOCKING DEVICE FOR RELEASABLY ENGAGING A DRAW TO A DRAWER SLIDE", Austrian Patent No. 510706A4 "KUPPLUNGSVORRICHTUNG FÜR SCHUBLADEN", Chinese Invention Patent No. 101548821 "Sliding rail adjustment device for drawers", etc., using various means to achieve adjustment of the hidden slide rail The purpose of the relative position of the drawers and furniture.
