Plug dislocation interlocking apparatus used by general-purpose converter

Abstract

The invention relates to a plug dislocation interlocking apparatus used by a general-purpose converter. The apparatus comprises a location plate and an interlocking slide block; a plurality of parallel linear grooves are opened on the location plate; folded grooves that are corresponded to the linear grooves are opened on the interlocking slide block; upper end spacings of the folded grooves are the same as spacings of the corresponded linear grooves of the location plate; a lower end spacing of each the folded groove is different from the spacing of the upper end groove of each the folded groove; and a central portion of the two ends of each the folded groove is in a sloped surface mode for transition; besides, handles that are connected with all plugs pass through the folded grooves of the interlocking slide block and can be moved up and down along the linear grooves on the location plate; and simultaneously, the interlocking slide block is driven to make translation movements left and right. According to the apparatus provided in the invention, it is utilized that spacings of the folded grooves and the linear grooves are not equal; therefore, when any type of plug is slipped off, an interlocking slide block is moved and dislocation of grooves and grooves is formed, so that other plugs are blocked by the slide block and can be slit downwardly; and thus the dislocation interlocking function is realized; moreover, a movable pin is utilized to realize position location, thereby improving security and reliability of the general-purpose converter.

Description

technical field [0001] The invention relates to an interlocking device, in particular to a plug dislocation interlocking device for a universal converter. Background technique [0002] Power plug socket is widely used in life as a kind of daily necessities. However, due to various reasons, the power plugs and sockets used in various countries have their own standards. In the high-speed process of integration in today's world, it brings a lot of inconvenience to people who often travel to and from different countries and regions for business, tourism, and visiting relatives and friends. Therefore, a converter that can change the plug is needed, which is what we call The universal converter has a variety of plugs at the same time. When in use, the correct plug can be extended and locked and then inserted into the corresponding standard socket, thereby completing the conversion between different standard sockets. [0003] When designing a universal converter, it is required t...

Problems solved by technology

[0004] Common universal converters are generally divided into two types at present, one is plug pop-up type, such as a kind of universal power converter disclosed in Chinese patent document CN201440551U, which adopts the method of setting multiple plugs to fold and pop up to realize the connection between different plugs. conversion, but due to the limitation of volume and other factors, the optional plug of this universal converter is limited, and it adopts the pop-up method, which cannot guarantee the stability and reliability of the plug; The disclosed universal power converter is provided with a plurality of plugs that can protrude along the chute, and the corresponding plugs are protruded through the slide button to realize the conversion between different plugs, but the selection and interlocking of the plugs are realized by using the switching slot arranged horizontally , the structure is relatively complex and difficult to operate
