A connection device and its safety cabinet

Abstract

The invention relates to the mechanical field, in particular to a connection device and a safety cabinet thereof. The connection device comprises a biting device and a limiting device, wherein one endof the biting device is a biting part, and the other end of the biting device is a free end; the biting part comprises a first biting arm which can extend into a mounting hole, and a second biting arm which is positioned on the outer side of the mounting hole and can cooperate with the first biting arm to form a biting gesture together with wall of a cabinet body; the limiting device comprises aconnection part connected with the cabinet body, and a limiting part which extends to the biting part, wherein the spacing part is used for preventing the biting part and the wall of the cabinet bodyfrom separating from biting cooperation; when a cabinet door is closed, the cabinet door drives the biting part to rotate around the wall of the cabinet body through the free end of the biting device;the first biting arm abuts against the inner side of the wall of the cabinet body; and the second biting arm abuts against the outer side of the wall of the cabinet body. By use of the connection device of the embodiment of the invention, through the arrangement of the biting device and the limiting device, the biting of the wall of the cabinet body is realized. When the cabinet door is completely closed, the first biting arm and the second biting arm of the biting device tightly bite the wall of the cabinet body to realize the seamless connection of the cabinet door and the cabinet body.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a connection device and a safety cabinet thereof. Background technique [0002] The use of cabinets can be seen everywhere in modern society. In many cases, the use of cabinets will have a safety level. For example, the use of power distribution cabinets must ensure that there are no gaps in the closed state of the cabinets to prevent small animals such as mice from entering the distribution cabinet and damaging the internal cables. , causing huge property losses and potential safety hazards. [0003] When the existing cabinet uses the inner rotating shaft connection device, there must be a little gap between the door and the cabinet body to ensure that the door can be opened. The security level needs to be improved. Contents of the invention [0004] The object of the present invention is to overcome the defects of the prior art, provide a connection device and a safety cabinet thereo...
