Description

Cabinet anti-tilt and inner lock device

technical field

The utility model relates to a drawer locking device for a cabinet body, in particular to an anti-tilt and inner locking device for a tool cabinet or a filing cabinet generally provided with several drawers.

Background technique

The conventional push-pull structure between the drawer and the box is provided with two corresponding rails between the two. By fitting each other, the drawer can be set inside the box and perform a push-pull action. Further, a stop block is provided on the corresponding two rails. Such as bumps or pieces, to avoid the danger of the drawer falling away from the box when the drawer is pushed and pulled.

Furthermore, the drawer is usually designed with a longer depth to increase the storage capacity, and in order to make the drawer completely pull out of the box body without deviating from the track, the drawer can be pushed into the box body immediately after taking and placing items. , further provided with three rails, such as a box slide rail, a middle slide rail, a drawer slide rail, and a stop block respectively arranged at predetermined positions at one end or both ends of each slide rail, after each slide rail is combined with each other sliding, and the stop blocks can block each other, so that the drawer does not need to be detached from the track and can have a large displacement to completely pull out the outside of the box, and prevent the drawer from falling out of the box; wherein, the above-mentioned Ball bearings are provided between the slide rails to reduce the friction force between the slide rails, so that the slide rails can easily slide with each other and reduce noise.

The above-mentioned tool cabinet or filing cabinet generally includes several drawers arranged up and down. After the tools or files are placed in each of the drawers, each drawer has formed a very heavy individual. The design of the slide rail group makes the drawer It is labor-saving and convenient to fully open the drawers. However, if the user does not pay attention, or an external force such as an earthquake makes the tool cabinet or filing cabinet tilt, so that some of the drawers are pulled out, the center of gravity There is a risk of the tool cabinet or filing cabinet tipping over due to a change in location.

Therefore, in order to prevent the danger of falling due to opening too many drawers, a slide rail locking structure has been developed to limit that only one drawer can be opened at a time. Once the drawer slides in one of the slide rail groups are pulled, the group of linkage devices will be activated to drive a connecting rod between the slide rail groups to prevent other slide rail groups from drawing. The drawer slide rail is pulled, such as U.S. Patent No. 5,352,030 is provided with a disc-shaped starting block at the rear end of the drawer slide rail, and U.S. Patent No. 5,634,701 is provided with a sloped starting block at the front end of the side of the drawer. U.S. Patent No. 5,988,778 is in A starting block is arranged at the front end of the drawer slide rail.

In each of the above-mentioned U.S. patents, some control elements are arranged on each slide rail group. Since the space on the slide rail group is not large, when these control elements are added, higher precision is required to cooperate with each slide rail group. The spatial location between them will increase the assembly cost relatively.
