Description
Technical Field
The utility model relates to a cubical switchboard technical field, concretely relates to screw combination spare for cubical switchboard.
Background
The switch cabinet is an electrical device, the external line of the switch cabinet firstly enters a main control switch in the cabinet and then enters a branch control switch, and each branch is arranged according to the requirement. Such as meters, automatic controls, magnetic switches of motors, various alternating current contactors and the like, and also high-voltage chamber and low-voltage chamber switch cabinets and high-voltage buses, such as power plants and the like. Because a plurality of electrical devices need to be installed in the switch cabinet, the requirements on the stability and the enough firmness of the switch cabinet are very high. And traditional for the cubical switchboard screw only through screwing up with the cabinet body coupling, this kind of connected mode poor stability, the contact is insecure, drops easily, has the potential safety hazard.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems, the to-be-solved technical problem of the utility model is to provide a screw combination piece for cubical switchboard that the contact is inseparable, stability is good, fixed firm, the security is good.
The utility model discloses technical scheme that screw assembly spare for cubical switchboard adopted is characterized in that include special-shaped screw and with the reference column of special-shaped screw complex, special-shaped screw includes screwhead portion, first axial region and second axial region, the second axial region is equipped with the screw thread, first axial region tip is equipped with first locking surface, screwhead portion tip is equipped with the second locking surface;
the positioning column is of a regular hexagon structure, a mounting hole is formed in the positioning column, a positioning column pressing surface, a first groove surface and a second groove surface are arranged, the first groove surface corresponds to the first locking surface, and a positioning column threaded part in threaded connection with the second shaft part is arranged between the first groove surface and the second groove surface;
and a riveting lug is further arranged at the end part of the positioning column.
The riveting lug is of a regular hexagon structure.
The first shaft portion has a diameter greater than a diameter of the second shaft portion.
The utility model discloses screw combination spare for cubical switchboard's advantage lies in: the structural design ensures that the anti-bending strength of the joint is higher, the contact is tighter and the stability is better; the design of the riveting bulge of the regular hexagon structure enables the other end to be connected in a riveting mode, and the installation and fixation are firm, and the positioning is fast and accurate.
