Abstract

A drawer seat with a locking device drawer for switching electrical appliances, including a slide plate and a drawer, the side plate of the drawer seat is provided with a chute for supporting the slide plate, and a mounting plate for installing the drawer is provided between the slide plate and the drawer Sliding structure, there is also a locking mechanism on the pull plate and the chute, the lock mechanism includes a button installed on the pull plate and a locking piece connected with the button between the pull plate and the slide plate, when the slide plate faces the pull plate There is a raised first limit piece on one side; when the pull plate is completely pulled out from the slide plate, the end surface of the locking piece away from the button is in contact with the first limit piece so that the pull plate cannot be retracted, The button can drive the locking part to move so that the locking part avoids the first limiting part. The drawer seat of the present invention can be reliably locked when the pull plate is pulled out, thereby ensuring the personal safety of the operator.

Description

technical field [0001] The invention belongs to the field of low-voltage electrical appliances, and more specifically relates to a drawer seat with a pull plate of a locking device for switching electrical appliances. Background technique [0002] With the rapid development of the global economy, the requirements for electrical products in the international market are also constantly increasing, and there are more and more dual power supply circuits. Automatic transfer switch appliances have become an important part of the dual power supply circuits of low-voltage electrical appliances. more and more widely. Especially in some high-current electric places where line inspection is required, the maintenance is convenient. This requires an automatic transfer switch device with isolation function, that is, with a drawer seat. In order to facilitate the body to be put into the drawer seat, the pull plate must require a locking device to ensure the safety of the operator, and th...
