Abstract

The utility model relates to a machine cabinet frame. The utility model present a rectangular body or a cubic body; the utility model is composed of twelve prisms and eight three-fork elements which form angle connection with three prisms, wherein each prism is a profile using a rectangular cavity as a vertex angle part and respectively extending an angle face to both sides, and the profile formed by compounding a second-order right-angle bending inner plate and a first-order right-angle bending outer plate; the edged surface is formed by that the end part of an outer layer plate passes around the outer edge of an inner layer plate and is folded inwards and stuck on the end of the inner layer plate after the outer layer plate is attached to the inner layer plate. The utility model has the advantage of simple fabrication; the utility model not only can reduce production cost but also can increase the rigidity of the frame and the interchangeability of the prisms.

Description

A kind of cabinet framework

The utility model relates to a kind of framework, relates in particular to a kind of cabinet framework.

The existing cabinet framework that is used to settle communication apparatus, disclosed as German patent DE 33 44 598, be a cuboid or square, this framework mainly is made up of eight trident spares of 12 prisms and three prisms of angle connection.Prism is to be pressed by the sheet metal progressive type to process.As shown in Figure 1, prismatic 1 is to be folded into one by a sheet metal be top corner part with rectangular enclosure 11 extend the section bar of first edged surface 12 and second edged surface 13 respectively to the two sides, and wherein, first edged surface 12 is by the back one-tenth single order right angle bending of inside and outside two-layer applyings; Second edged surface 13 is by behind the lamina rara externa 131 applying inner platings 132, and the end face 1321 that inner plating is walked around in the end 1311 of lamina rara externa bends inwards and pastes.This framework needs many operations in the course of processing, especially need the very high special equipment of expense, its producing cost costliness very when processing first edged surface 12.In addition, in case frame size determines that prismatic is corresponding one by one with framework, if will change frame size again, prism must correspondingly carry out adjusted size, therefore, and prismatic exchange poor performance.

The purpose of this utility model is to provide a kind of can reduce production cost, processing is simple, and the cabinet framework of parts interchangeability can be provided.

To achieve these goals, the utility model, it is a kind of cabinet framework, it is the framework of a cuboid or square, eight trident spares by 12 prisms and three prisms of angle connection are formed, it is characterized in that: described prism is that to be compounded to form one be top corner part extends an edged surface respectively to both sides section bar with the rectangular enclosure to the outside plate by the inner panel of second order right angle bending and the bending of single order right angle, described edged surface is by behind the lamina rara externa applying inner plating, and the outside that inner plating is walked around in the end of lamina rara externa bends inwards and is covered on the end of inner plating.

Owing to adopted above-mentioned technical solution, prism of the present utility model only needs general bender and spot welding machine to make, and does not need very big investment in production equipment, and processing is simple, and has increased the rigidity of framework, has improved prismatic interchangeability simultaneously.

Be further described of the present utility model below in conjunction with embodiment and accompanying drawing.

Fig. 1 is the sectional view of the prism of existing cabinet framework;

Fig. 2 is the sectional perspective exploded view of cabinet framework of the present invention;

The sectional view of the prism of Fig. 3 cabinet framework of the present invention.

As Fig. 2, shown in Figure 3, the utility model cabinet framework, it is the framework of a cuboid or square, eight trident spares 2 by 12 prisms 1 and three prisms of angle connection are formed, described prismatic 1 is that to be compounded to form one be top corner part extends an edged surface 13 respectively to both sides section bar with rectangular enclosure 11 for outside plate 14 by the inner panel 15 of second order right angle bending and the bending of single order right angle, described edged surface 13 is by behind the lamina rara externa 131 applying inner platings 132, and the outside 1321 that inner plating is walked around in the end 1311 of lamina rara externa 131 bends inwards and is covered on the end of inner plating.

Claims

1. cabinet framework, it is the framework of a cuboid or square, eight trident spares (2) by 12 prisms (1) and three prisms of angle connection are formed, it is characterized in that: described prism (1) is that to be compounded to form one by the outside plate (14) that the inner panel (15) of second order right angle bending and single order right angle bend be top corner part extends an edged surface (13) respectively to both sides section bar with rectangular enclosure (11), described edged surface (13) is by behind lamina rara externa (131) the applying inner plating (132), and the outside (1321) that the end of lamina rara externa (1311) walk around inner plating bends inwards and is covered on the end of inner plating.
