Description
Technical field
The utility model relates to the transmission equipment accessory structure, specifically is a kind of switch cabinet door support structure that the switch cabinet door opening positions that is used for.
Background technology
In the existing switch cubicle, be in the state that can rotate freely around hinge after its cabinet door is opened usually, both be not easy to the installation and maintenance of switch cubicle, bring potential safety hazard also for easily the installation and maintenance scene of switch cubicle.
Summary of the invention
Technical problem to be solved in the utility model is, provide a kind of simple in structure, the location is reliable, can multistagely locate, easy to operate switch cabinet door support structure.
Switch cabinet door support structure of the present utility model comprises a cabinet door that is connected through the hinge on the switch cabinet body doorframe; Be fixed with the location-plate of a level on the horizontal gird of switch cabinet body doorframe, have a line channel on the location-plate, the rear end of line channel has the end location hole of a diameter greater than the line channel width; Be provided with the connecting rod of a level in cabinet door inboard, rod rear end and cabinet door are hinged, and the connecting rod front end is connected with a pin that central shaft is vertical; Described pin is divided into different four sections of diameter from top to bottom, be followed successively by upper limit section, positioning section, guide section, lower limit section, wherein upper limit section diameter is greater than above-mentioned end location hole, the positioning section diameter is less than the end location hole and greater than the width of line channel, the diameter of guide section is less than the width of line channel, and the diameter of lower limit section is greater than the end location hole; Described pin passes location-plate, and the guide section of pin can slide along line channel.
Described line channel stage casing also is provided with at least one interfix hole, and the diameter in interfix hole is suitable with the end location hole.
The front end of described line channel also has a pin and penetrates the hole, pin penetrate outside the impulse stroke that the hole is positioned at pin and its diameter greater than the maximum gauge of pin.
The utility model is simple in structure, manufacturing and easy for installation; During its work, pin can be automatically positioned in end location hole or the interfix also in cabinet door opening procedure, make the cabinet door keep certain aperture and can not rotate freely, both made things convenient for the installation and maintenance of switch cubicle, and also can not bring personal injury because of freely rotating of cabinet door to the installation and maintenance personnel; Because the quantity and the position in interfix hole can be provided with arbitrarily, thereby can make the cabinet door have multistage aperture, have satisfied the needs of different occasions.
