Abstract
The utility model relates to a hinge for an iron cabinet, in particular to a circuit conduction type door hinge, which comprises a hinge seat, a hinge shaft and a hinge sleeve, wherein the hinge shaft is fixedly connected onto the hinge seat. The circuit conduction type door hinge is characterized in that the hinge sleeve is inserted into the hinge shaft by the aid of a push-shovel gasket, a plurality of projecting edges arranged on both two surfaces of the push-shovel gasket scrape surfaces contacting with the projecting edges, the front surface and the back surface of the push-shovel gasket are respectively provided with three projecting edges, and the projecting edges evenly arrayed on a circumference are in the shapes of cones, push shovels, triangular pyramids, pyramids and arrowheads. As the hinge sleeve is inserted into the hinge shaft by the aid of the push-shovel gasket, the projecting edges on the push-shovel gasket can pierce a paint layer, an oxidation layer or a rust layer remaining on the work surface of the hinge sleeve, thereby improving conductive contact between a door plate and the cabinet, enhancing continuity of a grounding protective circuit of the iron cabinet and accordingly avoiding the danger of electric shock in door opening.
Description
Technical field
The utility model is a kind of hinge that is used on the iron cabinet, particularly a kind of circuit turn-on formula door hinge.
Background technology
The electric a complete set of equipment of many high-low pressures all is installed in the iron cabinet of welding fabrication, and for security needs, cabinet must be taked grounding measures, and the mode of grounding measures is that grounding nut is set on cabinet, by grounding nut ground wire is connected with the stratum.Iron door-plate all is installed on the cabinet; door-plate is to be connected with cabinet by hinge; there is the part paint films to make that the conduction contact is unreliable between door-plate and the cabinet owing to residual between the hinge bonding surface; the continuity index that is the ground protection circuit of iron cabinet does not reach requirement, just may appear at the danger that electric shock takes place when opening the door.
Summary of the invention
The purpose of this utility model is to make the insecure defective of conduction contact between door-plate and the cabinet in order to overcome existing door hinge, invents a kind of circuit turn-on formula door hinge that can root out paint films automatically.
The purpose of this utility model realizes as follows: described circuit turn-on formula door hinge, comprise hinged seat, jointed shaft and hinged cover, jointed shaft is fixed on the hinged seat, it is characterized in that: hinged cover is plugged on the jointed shaft by a shoveling packing ring, the two sides of shoveling packing ring is equipped with a plurality of protruding swords, and protruding sword has the effect of scraping to the face of contact with it.
Protruding sword on the described shoveling packing ring is each three of positive and negatives, and it is evenly arranged on the circumference.
Being shaped as of described protruding sword: taper shape, shoveling shape, triangular taper, rectangular pyramid shape, arrow-shaped.
Good effect of the present utility model is as follows: because hinged cover is to be plugged on the jointed shaft by the shoveling packing ring; so under the effect of door-plate own wt and in the motion of door-plate Push And Release; make protruding sword on the shoveling pad can puncture the iron rust layer that the skin of paint of its working surface remnants or oxide layer and hinge are produced in long-term use; so just improved and conducted electricity contact between door-plate and the cabinet; improve the continuity of the ground protection circuit of iron cabinet, thereby avoided when opening the door, taking place the danger of electric shock.
Description of drawings
Fig. 1 is the utility model structure chart
Fig. 2 is five kinds of example structure figure of shoveling packing ring
Among the figure: 1 hinged seat, 2 jointed shafts, 3 hinged covers
4 shoveling packing rings, 5 protruding swords
The specific embodiment
As shown in Figure 1, described circuit turn-on formula door hinge, comprise hinged seat 1, jointed shaft 2 and hinged cover 3, jointed shaft 2 is fixed on the hinged seat 1, it is characterized in that: hinged cover 3 is plugged on the jointed shaft 2 by a shoveling packing ring 4, the two sides of shoveling packing ring 4 is equipped with a plurality of protruding swords 5, and 5 pairs of faces that contact with it of protruding sword have the effect of scraping.
Protruding sword 5 on the described shoveling packing ring 4 is each three of positive and negatives, and it is evenly arranged on the circumference.
Being shaped as of described protruding sword 5: A taper shape, B shoveling shape, the taper of C triangular, D rectangular pyramid shape, E arrow-shaped.
Because hinged cover is to be plugged on the jointed shaft by the shoveling packing ring; so under the effect of door-plate own wt and in the motion of door-plate Push And Release; make protruding sword on the shoveling pad can puncture the iron rust layer that the skin of paint of its working surface remnants or oxide layer and hinge are produced in long-term use; so just improved and conducted electricity contact between door-plate and the cabinet; improve the continuity of the ground protection circuit of iron cabinet, thereby avoided when opening the door, taking place the danger of electric shock.
