Embodiment Construction

[0009] The following specific examples are combined with the attached Figure 1-2 The present invention will be described in detail.

[0010] According to the embodiment, the distribution box provided with the air passage includes a box device for accommodating power distribution components. The hinged door 5 hinged by the bearings 31 at the upper and lower parts of the box body 3, wherein the hinged shaft 4 includes manipulation protrusions 41 arranged at the upper and lower ends, and the manipulation protrusions 41 are positioned away from the hinge. The direction of the cylindrical main body part 40 of the shaft 4 includes a shoulder part 411 and a conical part 42 in turn. The cavity 30 in the carrier 31 is provided with a positioning slider 313, and the center of the positioning slider 313 is provided with a cone. A tapered bush 310 is fixedly attached to the shaped hole to engage with the conical portion 42 and form a frictional fit, and the positioning slider 313 is fix...

Abstract

A distribution box provided with an air flow channel includes a box body device used for accommodating distribution components, the box body device includes a box body (3) and a hinged door (5) hinged with bearing pieces (31) fixedly arranged at an upper part and a lower part of the box body (3) through a fixedly connected hinged shaft (4), the hinged shaft (4) includes manipulation protrusions (41) arranged at upper and lower ends, the manipulation protrusions (41) include shoulder parts (411) and cone parts (42) in sequence in directions away from a cylinder main body part (40) of the hinged shaft (4), positioning slide blocks (313) are arranged in cavities (30) in the bearing pieces (31), and tapered bushings (310) are fixedly attached to taper holes arranged in the centers of the positioning slide blocks (313) to be jointed with the cone parts (42) thereby forming friction type fit.

Description

technical field [0001] The present application relates to the field of power distribution, in particular to a distribution box provided with an air flow channel. Background technique [0002] It is known in the art that various power distribution components are arranged in the power distribution box provided with air channels for operation by users, so as to complete the power distribution function. Various power distribution components in these distribution boxes may be those components known in the art, and will not be explained in detail in the present invention. [0003] In order to facilitate the user's operation, the distribution box is often provided with a revolving or hinged door, which is used to open the distribution box to operate the power distribution components therein, or to maintain the electrical components in the distribution box. But, for the control of the opening angle or opening amount of this hinged door, there is no convenient and reliable device fo...
