Abstract

The utility model provides sections for a casing or a door of an electric apparatus. The utility model is all sheared strips, wherein, the cross section of the sheared strip of the section for a casing of an electric apparatus is C-shaped, both ends of a C-shaped opening are respectively provided with an installing groove; the section for a door of an electric apparatus is a sheet strip, whose surface is a plain face or a bend surface; one side of the sheet strip along the strip lengthwise direction is winded with an installation through hole or convexly provided with an axis. The sheared strips of the sections are unloaded to assemble when the casing products of the electrical apparatuses are manufactured, and each electrical apparatus casing factory can save each tool or mold for manufacturing the casing and the door. The utility model has the advantages of labor saving, material saving, commonality increasing, and easy fabrication, and the utility model is favorable to the serialization, the development and the update of the electrical apparatus casing products.

Description

Sections for casing or door of electric apparatus

The utility model relates to a kind of special-purpose section, and a kind of section bar as electric equipment casing and chamber door is in particular as the casing of miniature electrical equipment case and the section bar of chamber door.

Existing miniature electrical equipment case, casing and chamber door all adopt thin-slab structure, by sheet blanking, process through dashing, draw, pressing, each electric component box manufactory must provide processing mold separately for oneself, take a lot of work, take material, and electric component box product versatility is poor, during the production development seriation, worker, mould increase thereupon, the development of product is upgraded, and is also restricted.

The purpose of this utility model is to provide a kind of special-purpose section that is used to make electric equipment casing and door, all make billot, can get final product according to a required cun blanking assembling to the greatest extent when making electric component box, each electric component box manufactory can remove worker, the mould of making casing and chamber door from, but both saving of labor, material-saving, can increase versatility again, the convenient manufacturing helps electric component box product seriation and development, upgrading products.

Technical solution of the present utility model is the section bar as the electric equipment casing, and section bar is a billot, and the cross section of billot is " C " type, respectively has mounting groove at the two ends of " C " type opening; As the section bar of electric equipment chamber door, section bar is the thin plate billot, and the surface of thin plate billot is plane or bending curved surface, has rolled along the billot length direction at a lateral edges of thin plate billot and through hole has been installed or is raised with installation shaft.

Referring to accompanying drawing 1,2,3,4.

Accompanying drawing 1 the utility model casing section bar figure

Accompanying drawing 2 the utility model chamber door section bar figure

Figure is used in the assembling of accompanying drawing 3 the utility model casings

Figure is used in the assembling of accompanying drawing 4 the utility model chamber doors

The utility model further specifies as follows in conjunction with specific embodiments, section bar as the electric equipment casing is a billot, the cross section of billot is " C " shape, its " C " shape has the rectangle of breach for middle part, one side, two open end at the opening rectangle respectively have a U-lag, and casing section bar billot adopts aluminium alloy to draw and forms.When casing section bar billot was made the electrical Jackbox use, socket was installed in the U type mounting groove at opening two ends, casing section bar " C " type cross section, the shrouding suit sealing of casing section bar two ends.Referring to accompanying drawing 3.Section bar as the electric equipment chamber door, section bar is the thin plate billot, and the surface of thin plate billot is that the bending of three sections planes is connected the bending curved surfaces that form, and is made of metal or plastics are made, lateral edges at the thin plate billot has been rolled the installation through hole along the billot length direction, " C " shape of Kong Zhouwei opening.When making the chamber door use, chamber door thin plate billot two ends, the installation through hole of a side is loaded on the end plate at chamber door two ends with bolt sleeve.Referring to accompanying drawing 4.

The utility model has the advantage of that electrical equipment box body and chamber door all can be made into the section bar billot, when making the electric component box product, the blanking of section bar billot can be assembled, each electric component box manufactory can remove worker, the mould of making separately casing and chamber door from, both but saving of labor, material-saving can increase versatility again, the convenient manufacturing, be conducive to electric component box product seriation and development, upgrading products.
