Description
Technical field
This utility model relates to the technical field of frame structure in a kind of card insert type electronic equipment, and especially one is used for
The receiving of pcb board card, assemble and fixing frame structure.
Background technology
Card insert type electronic equipment generally requires a set of framework accommodate, assemble and pcb board card in fastening apparatus, mesh
Front common frame structure is generally made up of the combination of framework, side plate, backboard and guide-track groove, needs to make in advance under this kind of structure
Fixed corresponding framework, then side plate, backboard are fixed on framework, overall assembly process increases, and production efficiency is relatively low；And in one
In formula frame structure, galvanized steel plain sheet, electrolytic zinc-coated steel sheet etc. being stamped to form by diel, wherein customization diel is a master
Want cost, particularly especially prominent in the case of product amount is less, thus the manufacturing cost of integral device can be increased.
How can manufacture one and to be beneficial to add on the premise of ensureing manufacturing cost and framework two side rails spacing accuracy
Work manufactures, the frame structure of simple in construction, is the research staff of industry technical problem urgently to be resolved hurrily.
Summary of the invention
In view of this, the deficiency that this utility model exists for prior art, it is provided that a kind of pcb board card frame structure,
Utilize numerical control press, feature that numerical control bending precision degree of controllability is higher, designed by rational structure, reduce being manufactured into of framework
Basis, and precision and the perpendicularity of backboard of framework two side rails spacing can be improved simultaneously, simplify the framework knot of pcb board card
Structure, thus improve production efficiency.
For achieving the above object, this utility model is adopted the following technical scheme that
A kind of pcb board card frame structure, including main frame, left plate, right plate and guide rail, it is characterised in that: main frame
It is bent into U-shaped after clipped punching, integrally formed, at described end face away from backboard by end face, backboard, three, bottom surface part respectively
An end margin there is upwardly extending upper edge, under described bottom surface has away from an end margin of backboard and to downwardly extend
Edge part；Left plate and right plate are respectively provided with location bending part and lower location bending part respectively, described upper location bending part with
The upper edge of main frame is fixed, and the lower edge portion of described lower location bending part and main frame is fixed.
Preferably, described left plate and right plate are L-shaped, when with main frame secure fit, and the one side of bending in L-shaped
The backboard of main frame is surrounded from outside.
Preferably, described upper location bending part welds location, described lower location bending part and lower edge portion with upper edge
Welding location.
Preferably, described guide rail is separately positioned on the lower end of end face and the upper end of bottom surface of main frame.
Preferably, described upper edge is vertically arranged and end face, and described lower edge portion is vertically arranged and bottom surface.
Relative to prior art, this utility model has a following beneficial effect:
Without manufacturing framework, production efficiency can be improved；Lower-cost material fabrication and processing can be used, it is not necessary to punching press
Mould i.e. can get the product of degree of precision, can reduce production cost；By arranging upper and lower location bending part and upper and lower limit
Edge, by coordinating between location bending part and edge part, it is ensured that the perpendicularity of backboard, such that it is able to improve main frame
The receiving of the precision of two side rails spacing, beneficially pcb board card, assemble and fasten.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of a kind of detailed description of the invention of the present utility model.
Description of reference numerals:
1-main frame, 2-left plate, 3-right plate, 1.1-end face, 1.2-backboard, 1.3-bottom surface, 1.4-top
Edge, 1.5-lower edge portion, 2.1-positions bending part, positions bending part under 2.2-, 3.1-positions bending part,
