Abstract
The utility model relates to a hinge of a power distribution cabinet door, which comprises a base fixed on a cabinet body, a turning block and a shaft pin; the turning block is positioned on the middle part of the base; one end of the turning block is movably connected with the base into a whole by the shaft pin; the base is a groove-shaped integrated member; as the base is the integrated member, the door hinge can not enlarge the clearance between structural members caused by the gravity of a door panel in the process of transporting a power distribution cabinet, thereby reducing the matched clearance between the cabinet door and the cabinet body, improving the locking accuracy between the cabinet door and the cabinet body, and reducing the assembling difficulty.
Description
Technical field
The utility model relates to a kind of hinge, particularly relates to a kind of Hinge for cupboard door that power distribution cabinet cabinet door is connected with cabinet that is used to connect.
Background technology
The employed Hinge for cupboard door of electrical power distribution cabinet is generally the branch body structure in the prior art, comprise the base 21 that is fixed on the cabinet, moving block 23 and the pivot pin 22 that is connected base and moving block, wherein, described base comprises upper bed-plate and lower bottom base, described moving block 23 is integral by the 21 perpendicular flexible connections of pivot pin 22 and described base, the power distribution cabinet Hinge for cupboard door of this structure, because the employing of door hinge divides body structure, and the cabinet door is heavy generally at 10kg～30kg, in power distribution cabinet installation and transportation, because of the door-plate action of gravity, factor affecting such as the transportation power distribution cabinet is squeezed, can cause the distortion of power distribution cabinet door-plate, thereby cause the fit clearance of door hinge structural member to strengthen, cause lockhole to be difficult to closure, reduced the interlocking accuracy of cabinet door and cabinet, in addition, because each parts is the direct contact friction of metalwork, cause the surfacing damage layer, cause corrosion, and in plant produced, divide body structure because door hinge adopts, and be unfavorable for the assembling of parts, can not be adapted to streamline production, increase mounting hardness, thereby influenced operating efficiency.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of power distribution cabinet door hinge fit clearance, power distribution cabinet Hinge for cupboard door simple in structure and easy to assembly of reducing.
In order to solve the problems of the technologies described above, a kind of power distribution cabinet Hinge for cupboard door of the utility model, comprise base, moving block and pivot pin, wherein, described base is fixed on the cabinet, described moving block is positioned at described base middle part, and an end of described moving block is hinged by pivot pin and described base, and described base is a flute profile integrated member.
Above-mentioned a kind of power distribution cabinet Hinge for cupboard door, wherein, above-mentioned pivot pin is the annular knurl pivot pin.
Above-mentioned a kind of power distribution cabinet Hinge for cupboard door wherein, is provided with the plasticity packing ring between above-mentioned moving block and the base contact surface.
Above-mentioned a kind of power distribution cabinet Hinge for cupboard door, wherein, above-mentioned plasticity packing ring is a nylon washer.
Adopt a kind of power distribution cabinet Hinge for cupboard door of said structure, because its base is an integrated member, door hinge with regard to not can because of power distribution cabinet in transportation door-plate gravity and strengthened gap between structural member, thereby reduced the fit clearance of cabinet door and cabinet, solved and wanted hand assembled and base separated into two parts to be fixed on the cabinet in the prior art, cause dislocation up and down easily, pivot pin is difficult to inject the problem of base; Improve the accuracy of interlocking between cabinet door and cabinet, reduced the assembling difficulty; Because pivot pin is the annular knurl pivot pin, strengthened the surface roughness of pivot pin and base contact surface, be connected more firmly thereby make between pivot pin and the base, gap between the two is littler.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
In order to solve the problems of the technologies described above, a kind of power distribution cabinet Hinge for cupboard door of the utility model, comprise the base 1 that is fixed on the cabinet, moving block 2 and pivot pin 3, wherein, moving block 2 flexibly connects with described base 1 by pivot pin 3 and is integral, moving block 2 is perpendicular with base 1, moving block 2 is positioned at the middle part of base 1, described base 1 is an integrated member, side at base 1 is provided with a groove, and its plane is provided with installs screw 11, and an end of described moving block 2 is positioned at described groove, pivot pin 3 passes an end of base 1 and moving block 2, moving block 2 and base 1 are linked into an integrated entity, and the base 1 of this structure can process on lathe, wants hand assembled and base separated into two parts to be fixed on the cabinet in the prior art thereby solved, cause dislocation up and down easily, pivot pin is difficult to inject the problem of base; Described pivot pin 3 can be general pivot pin, also can be the annular knurl pivot pin, described annular knurl pivot pin then is that the outer peripheral face at usually used pivot pin 3 is provided with annular knurl, thereby increase the roughness of contact surface, make the connection of pivot pin 3 bases 1 more solid and reliable, also can between the contact surface of moving block 2 and base 1, respectively be provided with a plasticity packing ring 12, thereby can the plastic strain by plasticity packing ring self eliminate the gap and can reduce moving block 2 and base 1 between pivoting friction, the noise that is produced in the time of can reducing switch, plasticity packing ring 12 adopts nylon washer in the utility model; The afterbody of described moving block 2 and base 1 can be circular arc, and the afterbody circular shape of moving block 1 and base 1 is not only attractive in appearance but also can make the rotation of power distribution cabinet cabinet door slick and sly more.
Described base 1 is fixed on the cabinet, pivot pin 3 passes moving block 2 and base 1, an end of moving block 2 and base 1 is flexibly connected be integral, and the other end of moving block 2 is fixed on the cabinet door, moving block 2 just can rotate around pivot pin 3, and then the cabinet door of the moving block other end just can freely open or close.
Adopt a kind of power distribution cabinet Hinge for cupboard door of said structure, because its base is an integrated member, door hinge with regard to not can because of power distribution cabinet in transportation door-plate gravity and strengthened gap between structural member, thereby reduced the fit clearance of cabinet door and cabinet, improve the accuracy of interlocking between cabinet door and cabinet, reduced the assembling difficulty; And base can be processed on lathe, has improved operating efficiency.
