Abstract
The utility model discloses a section bar chassis comprising a section bar frame and two cover plates (1). The section bar frame is formed by jointing a rear panel (2), a front panel (3) and two side plates (4). The rear panel (2), the front panel (3) and the side plates (4) have a same section bar section. Upper ends and lower ends of the rear panel (2), the front panel (3) and the side plates (4) are all provided with a rib (5) in the section bar extension direction. Both of the head ends of the two side plates (4) are arranged in a manner that the head ends are vertical to the rear panel (2) and arranged on the rear panel (2) symmetrically. The rear panel (2) is connected with internal threads on open through holes (6) in upper ends and lower ends of the two side plates (4) through four screws separately. The front panel (3) and the rear panel (2) are arranged on two ends of the side plates (4) symmetrically. The section bar chassis of the utility model has the advantage of low cost, the machining accuracy can be easily ensured, the maintenance is convenient, the length and width dimensions of the chassis can be adjusted freely, and the section bar chassis is suitable for advanced research and small-lot production.
Description
Technical field
The utility model relates to carrying electronic devices and components or electronic equipment cabinet technical field, particularly a kind of section chassis.
Background technology
At present, the cabinet using in electron trade, mainly as the carrier of electronic equipment, along with continuing to optimize of electronic device, is weeded out the old and bring forth the new; The electronic equipment of beforehand research and small lot batch manufacture is more and more.Simultaneously along with the miniaturization of electronic equipment and the increase of functions of the equipments, the quality of fit that is arranged on electronic equipment in cabinet and cabinet is also more and more higher.Once the size of electronic equipment changes, cabinet also needs to make corresponding adjusted size.At present, for the electronic equipment chassis of beforehand research and small lot batch manufacture, people also adopt the mode of mechanical Milling Process to manufacture such electronic equipment chassis, although can ensure quality of fit, but efficiency low, wasted manpower, with high costs.
Utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, with low cost, be easy to ensure machining accuracy, easy to maintenance, the length and width size that can freely adjust cabinet; Be applicable to the section chassis of beforehand research and small lot electronic equipment.
The purpose of this utility model is achieved through the following technical solutions: a kind of section chassis, it comprises section material framework and two cover plates, section material framework is by rear board, front panel and two side plates are spliced, described rear board, the section bar cross section of front panel and side plate is identical, rear board, front panel and side plate upper, lower two ends are along being provided with fin on section bar draw direction, on each fin, be provided with opening shape through hole, between each fin and profile flange, be formed with guide groove, in opening shape through hole, be provided with internal thread, two side plate head ends are all perpendicular to rear board setting and be symmetricly set on rear board, rear board by four screws respectively with two side plates on, internal thread on the opening shape through hole of lower end connects, front panel and rear board are symmetricly set on two ends of side plate, four limits of two cover plates are separately positioned on front panel, on two side plates and rear board, in the guide groove of lower end.
Described cover sheet thickness is less than the groove width of guide groove.
The utlity model has following advantage: (1) section material framework of the present utility model is by front panel, two side plates and rear board are spliced by screw, and rear board, the section bar cross section of front panel and two side plates is identical, along being provided with fin on section bar draw direction, on each fin, be provided with opening shape through hole, between each fin and rear board edge, be formed with guide groove, in opening shape through hole, be provided with internal thread, therefore, this section chassis only need use a mould just can produce the section bar of this cross sectional shape, by section bar is processed by Production requirement, finally with screw, section bar is spliced into required section material framework, can ensure like this quality of fit between each section bar, and easy to process, shorten process time.(2) rear board is fastened on two side plates with the internal thread of the opening shape through hole of two side plate upper and lower ends respectively by four screws; Front panel is arranged on two side plates perpendicular to two side plate ends and is connected with the internal thread of the opening shape through hole of two side plate upper and lower ends respectively by four screws.This cabinet has easy disassembling, feature solid and reliable, simple in structure.(3) cover plate four limits are separately positioned in the guide groove of front panel, two side plates and rear board upper and lower end.Cover plate is fixed without any screw, has both ensured quality of fit, has reduced again the use of screw, has reduced cost, has strengthened the maintainability of product.
