Description

Drawer Interlocking Locking Structure of Tool Cabinet

technical field

The utility model relates to a drawer interlocking locking structure of a tool cabinet, in particular to an interlocking locking that can simultaneously reach the drawer locking state or release the locking state with the opening and closing action of the upper cover plate of the tool cabinet body structure.

Background technique

In order to facilitate users to effectively classify and summarize the tools at home, various tool cabinets have appeared. Most of the existing tool cabinets are surrounded by four-sided panels, upper cover plates and lower bottom plates between the corner columns at four ends to form a tool cabinet. The main body, the top of the tool cabinet body is an open end that can be opened or closed by the upper cover, and a partition can be arranged in the tool cabinet body, and the partition and the upper cover form a tool storage space, and at least one side panel has an open end, which allows the drawer to be horizontally slid and extracted in the tool cabinet body. Since users often have to push and pull the tool cabinet to a suitable operating place, in order to prevent the drawer from sliding during the push and pull process Get out of the tool cabinet, and the tool cabinet is equipped with a drawer locking structure.

The traditional drawer locking structure adopts the locking method of individual drawers, such as those disclosed in Taiwan Patent Publication No. 137421 and No. 313187, but because users often need to use the tools after pushing and pulling the tool cabinet, If the drawers are locked one by one, it will cause time-consuming and inconvenient operation for the user. For this reason, a tool cabinet with a drawer interlocking locking device has been proposed, such as disclosed in U.S. Patent No. 6,347,848, No. 6,572,203, and No. 6,742,854 In the locking devices of each patent, a slide rail seat is provided on the inner wall of the tool cabinet, and a limit body with a locking hole is provided on the slide rail seat, and a stopper that can be locked with the locking hole is provided at the rear end of each drawer. The locking member with the hole forming a locking relationship uses a force-applying part (such as the connecting rod design of No. 6347848) to move the limit body downward, so that the locking hole and the locking member form a drawer locked state, and are described in various patent documents It also emphasizes that if one of the drawers is not fully pushed into the locked state, the drawer can be directly pushed into the tool cabinet, and the locking piece of the drawer can push the limit body to allow the locking piece to enter the locking hole locked inside.

However, the structure of the locking device in the above-mentioned patents is quite difficult to assemble, and although the second-time application of force locking has merits, it causes troubles for the user. When the limiter is used, it will release other drawers that have completed the locked state at the same time, and it will also cause other drawers that have completed the locked state to come out. In addition to the locking method, the implementation methods of other patent documents require the user to use a key to turn the connecting rod and other manual methods, which is quite inconvenient. However, in Figure 5 of the No. 6572203 patent, the upper cover plate and the limiter are separated. The moving parts are connected and linked, and the first sliding part and the second sliding part are arranged on the limiter. Not only is the actual operation and assembly inconvenient, but the moving part is also easy to scratch the upper cover and affect its aesthetics.
