Abstract
The utility model relates to a hingeless instrument door for a ring main unit. The technical problem to be solved is that the provided instrument door should have the advantages of simple structure, convenient installation, flexible rotation and smooth door body. The adopted technical scheme is that: the hingeless instrument door for the ring main unit comprises a door body which is rotatably mounted on a cabinet body, and the upper end and the lower end of the door body are provided with flanges folding inwardly. The hingeless instrument door for the ring main unit is characterized in that: the door body is rotatably mounted on the cabinet body through a supporting column; the flanges at the upper and lower ends of the door body are respectively and rotatably riveted on the upper end surface and the lower end surface of the supporting column through two rivets positioned on the same axis; the supporting column is fixed on the cabinet body through screw bolts; and the rivets are self-plugging rivets.
Description
Technical field
The utility model relates to a kind of electric equipment, specifically is a kind of for the instrument door on the ring main unit.
Background technology
Ring main unit is a kind of metal cabinet that holds high voltage switchgear, is widely used in the power distribution station and box-type substation of residential quarters, skyscraper, large public building and factory and enterprise.The instrument door is installed on the ring main unit cabinet, and the instrument door must reach certain degree of protection, and satisfies the specification requirement of electrical safety.
Existing instrument door generally is to be connected on the cabinet by back-flap hinge (or blind hinge), and hinge is comparatively loaded down with trivial details when mounted, is unfavorable for enhancing productivity; Simultaneously, the rotating shaft of hinge protrudes from instrument every body, has also influenced the aesthetics of door surface.
The utility model content
The purpose of this utility model is the deficiency that overcomes in the above-mentioned background technology, and a kind of novel hinge-less ring main unit instrument door is provided, and that this instrument door should have is simple in structure, easy for installation, rotate flexibly and the smooth characteristics of door body.
The technical solution of the utility model is: a kind of hinge-less ring main unit instrument door comprises: be rotatably installed on the door body on the cabinet, the top and bottom of door body are shaped on inwardly folding flange; It is characterized in that: described door body is rotatably installed on the cabinet by pillar.
The flange of described door body top and bottom is respectively by being positioned at upper surface and the lower surface that two rivets on the same axis are riveted on described pillar rotationally.
Described pillar by bolt on described cabinet.
Described rivet is self-plugging rivet.
The beneficial effects of the utility model are: door of the present utility model body is connected on the pillar by rivet, and not only structure is comparatively simple, and makes and install all very convenient, can enhance productivity greatly; Simultaneously, pillar is hidden in a body inside, and the rotation axis that has overcome hinge protrudes from the shortcoming of a surface, makes that the door surface is smooth smooth, and good looking appearance is generous.

Fig. 2 is the perspective view of the utility model B-C post.
Perspective view when Fig. 3 is the utility model combination.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in the figure, a kind of hinge-less ring main unit instrument door mainly comprises: door body 1 and pillar 2; The top and bottom of door body are shaped on the inwardly flange 1-1 of folding (being folded into 90 degree usually).
Be shaped on riveted holes 1-2 on the flange of door body, the upper surface of pillar and lower surface are shaped on the axis hole 2-1 with the riveted holes coupling; The flange of door body is fastened on upper surface and the lower surface of pillar, and riveted holes and axis hole all are positioned on the same axis, and rivet 3 is riveted on the door body on the pillar after passing through riveted holes and axis hole with direction shown in the arrow A.
Pillar on cabinet, generally adopts the cold drawing of 2mm to form through bending manufacturing by bolt, and the manufacture craft process is simple, and intensity also can be guaranteed.The door body with the rivet on the pillar as jointed shaft, can not have in the horizontal direction interferingly flexibly and rotate on (pillar wherein can make an inclined-plane 2-2 on a vertical rib, avoid interfering the motion of door body, conventional structure), the folding angle reaches the IP3X degree of protection greater than 120 degree; Rivet generally adopts the self-plugging rivet of stainless steel circle forward type, helps to promote bonding strength, and is also flexible especially during field riveting, is conducive to enhance productivity.
