A plurality of pin columns are arranged on the sliding piece and corresponded with each stop catch. When the drawer moves, the pin column is matched with the rail in a sliding or rolling way, the rail drives the sliding piece to move un-and-down through the pin column and the pin column is capable of matching with the stop catch or separating with the stop catch. The utility model is able to open one drawer at one time and is capable of preventing the box and cabinet from falling because of the change of the gravity center, thus, the utility model is safe and reliable and is not easy to damage the articles.

Description

Drawer is prevented many opening structures

Technical field

The utility model relates to a kind of stacked case, cabinet, table that is provided with a plurality of drawers, especially about preventing the structure that a plurality of drawers are opened simultaneously.

Background technology

Generally by a lockset control, when lockset was opened, all drawer was in state to be opened to a plurality of drawers of existing case, cabinet, table and so on article, and each drawer can be done the opening and closing operation; Otherwise, must after closing all drawers, can lock lockset.When the user draws back a plurality of drawers because of carelessness simultaneously, may the accident that bin is toppled over take place owing to mass centre changing, therefore, there is the hidden danger of safety and infringement article.

Summary of the invention

The purpose of this utility model is to provide a kind of anti-many opening structures of drawer that once can only open a drawer.

In order to achieve the above object, the technical solution adopted in the utility model is: a kind of drawer is prevented many opening structures, comprise cabinet and some drawers, cabinet and drawer plug together, the side of drawer is provided with track, the track front portion has the downing track section, the track rear portion has straight orbital segment, drawer side surface above the downing track section is provided with stop, is provided with sliding part at the cabinet sidepiece, on sliding part, be provided with several respectively with the corresponding pin of each stop, when drawer moves, pin slides or rolls along track, and track drives sliding part by pin and moves up and down, and pin can match or be separated with stop.

After adopting said structure, because the side of drawer is provided with track, the track front portion has the downing track section, the track rear portion has straight orbital segment, drawer side surface above the downing track section is provided with stop, be provided with sliding part at the cabinet sidepiece, on sliding part, be provided with several respectively with the corresponding pin of each stop, when drawer moves, pin slides or rolls along track, track drives sliding part by pin and moves up and down, and pin can match or be separated with stop, when opening wherein any drawer, along with drawing back of drawer, the track that is provided with on this drawer side surface can drive pin and slide into or be rolled into the straight orbital segment at track rear portion from the downing track section of track front portion, and pin rises relatively, drives whole sliding part and upwards slides, other pin on the sliding part then rises to the stop place of drawer separately, match with stop, thereby shelves are lived these drawers, prevent outside extraction; When closing this drawer, pin slides into or is rolled into the downing track section of track front portion from the straight orbital segment at track rear portion, pin descends relatively, driving whole sliding part descends, the pin of other drawer correspondence breaks away from the stop of drawer separately, also get back to the downing track section of drawer rail front portion separately, removed the lock-out state of these drawers.Can open any one drawer again afterwards, but other drawer will can not be opened by locking.The utility model once can only be opened a drawer, can effectively prevent owing to the accident that bin is toppled over takes place mass centre changing, and is therefore safe and reliable, is difficult for the infringement article.
