Abstract

The invention discloses a self-locking device. The self-locking device comprises a base used for being fixedly connected to an electric appliance, and two self-locking pieces arranged on one side of the base, wherein one end of each self-locking piece is fixed to the base, the other end of each self-locking piece is a free end, the two free ends are adjacent to each other, a V-shaped included angle is formed between the two self-locking pieces, and a fixing piece is inserted or pressed into the space between the two free ends to be locked to the electric appliance. The self-locking device has a high degree of fit with the fixing piece and is convenient to install, reliable in locking and capable of preventing the fixing piece from disengaging due to vibration in transportation; the fit clearance between the fixing piece and the self-locking device is small, it is not needed to use screws for fixing the fixing piece to the surface of the electric appliance any more, and the self-locking device can be shielded by the fixing piece when in use to beautify the appearance of the electric appliance; the self-locking device is simple in structure and simple in machining process, and thus the production cost can be easily reduced. The invention further discloses the fixing piece comprising the self-locking device. Locking of the fixing piece is reliable.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a self-locking device. In addition, the present invention also relates to an electrical appliance comprising the above self-locking device. Background technique [0002] At present, the components in household electrical appliances are usually connected by screws. Some of the screws are exposed outside the product, and some screws are hidden inside the product through the opening, but both of them will affect the appearance of the product. Fixing sheets are installed at the screw positions on the top to cover the screws or openings. [0003] A typical way of adding the fixing piece is to set screws on the top and bottom of the fixing piece, and fix the fixing piece to the electrical appliance through the screws. However, in this fixing method, the fixing piece may be squeezed and deformed, thereby increasing the matching gap with the installation surface of the el...
