Hinge device

Abstract

This device 1 has the hinge blade 3 composed of a blade body 31, a pin insertion hole 32, a pair of locking claws 33, 33, a positioning-fixing part 34 and stoppers 35, 35. When the hinge blade 3 is mounted to the door 7, the pair of locking claws 33, 33 of the blade body 31 are locked to both sides of a slit starting edge of a notch 70 (of the door 7) to fit and attach the blade body 31 onto the notch 70. The stoppers 35, 35 of the blade body 31 are brought into pressure contact with the inner surface of the door 7 to mount and fix the hinge blade 3 to the door 7.

Description

technical field [0001] The present invention relates to a hinge device, and more particularly to a hinge device used for a shelf or the like for storing electrical and electronic equipment and other various equipment. Background technique [0002] In general, a shelf for storing electrical and electronic equipment and the like is composed of a housing and a door, and the door is usually attached to the front of the housing through a plurality of hinges (devices) so as to be openable and closable. In this rack, the front of the cabinet is provided with a fixed frame, and one side portion of the door relative to the pivoting side of the cabinet is bent at approximately a right angle to form a free edge, forming a box shape. The hinge device used for this shelf is composed of the following parts: a hinge base on the side of the cabinet, which is installed on (one side of) the fixed frame of the cabinet; a hinge blade on the side of the door, which is connected to The hinge bas...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned existing hinge device, since the hinge base on the housing side is installed on one side of the fixed frame on the front of the housing by welding or mounting screws, the hinge blade on the door side is installed on the door by welding or mounting screws. There is a problem that the installation work of these hinge parts is complicated and difficult.

In addition, when these hinge bases and hinge blades are all mounted with mounting screws, a large number of mounting screws are required as a whole, resulting in an increase in the number of parts and a problem of high cost.
