Abstract
The utility model relates to an embedded guide track style plug box, comprising a cross beam, a straight beam, an angle bracket, a flat plate, a handle and an upper and a lower tracks made of aluminum alloy sections, which is characterized in that the track is composed of three types of track blocks having different widths and special cross-section shapes. Plug boxes and plugs of different width can select the track blocks of different width and quantity orderly embedded between the front cross beam and the middle cross beam or between the rear cross beam and the middle cross beam having corresponding cross-sectional shapes. The upper and lower edges of the printed plate of the plugs are aligned with and pushed into the guide slots of the upper and lower track blocks, and the plugs can be fixed in the plug boxes by rotating the locking devices on the rotary plugs.
Description
The utility model is a kind of body structure of instrument and equipment, particularly a kind of embeded guide track style body structure that is assembled by the section bar with special cross section shape.
Crosspiece that existing subrack is made by four aluminium alloy extrusions and left and right side plate and upper and lower guide rail constitute, and are a kind of series of products that form by different width, height and depth dimensions parameter combinations.It is the installing hole of 1/5 inch (5.08mm) that the subrack of every kind of width dimensions all needs with numerical control press punching out spacing on crosspiece, is used for fixing plug-in unit and guide rail, and to guarantee the required precision of assembling, this brings inconvenience just for the manufacturing and the use of product.
The purpose of this utility model provides a kind of embeded guide track style subrack, as long as select the way block combination of different in width, varying number, be inlaid between the crossbeam, promptly can be assembled into the subrack that meets international standard IEC297.3-84 " subrack and relevant plug-in unit dimension series ".
Way block of the present utility model, length is identical, but three kinds of accurate width dimensions are arranged, and has special shape of cross section.As long as way block is inlaid in the crossbeam with respective cross-sectional shapes, i.e. locking voluntarily, and do not need to be screwed.Select the way block combination of different in width, varying number, be arranged in order and carry out setting-in, just can obtain the subrack of various width dimensions.Like this, just can be assembled into the body structure of plurality of specifications with less parts, process equipment and time, assemble easy, highly versatile.
For ease of understanding formation of the present utility model, be specifically described below in conjunction with accompanying drawing:
Fig. 1 is the front view of the utility model subrack;
Fig. 2 is the vertical view of the utility model subrack;
Fig. 3 is the end view of the utility model subrack;
Fig. 4 is the utility model way block upward view;
Fig. 5 is the utility model way block front view;
Fig. 6 is the utility model way block vertical view;
Fig. 7 is the utility model way block left view;
Fig. 8 is the utility model front beam sectional drawing;
Fig. 9 is the utility model middle cross beam sectional drawing;
Figure 10 is the utility model rear cross beam sectional drawing.
With reference to Fig. 1, Fig. 2 and Fig. 3, connect into a framework with front pole-bracket 9, back pole-bracket 15, dull and stereotyped 12 by two aluminium alloy extrusions front beams 1, two or 2, two rear cross beams 3 of four middle cross beams and four straight beams 4.Front beam 1 and front pole-bracket 9 usefulness screws 11 are fixing with straight beam 4, and rear cross beam 3 is fixing with straight beam 4 by back pole-bracket 15 usefulness screws 13, and middle cross beam 2 is fixing with straight beam 4 by dull and stereotyped 12 usefulness screws 13.Load onto handle 17 at front pole-bracket and just constituted a subrack, just constituted a desktop chassis if refill left and right side plate 16, cover plate 5, base plate 10.Tool installing hole 14 at regular intervals is used to install middle cross beam 2 on the straight beam 4, selects the middle cross beam of varying number, can constitute the subrack of different depth size.Way block 6,7,8 with special cross section shape, be inlaid in side by side between the front beam and middle cross beam, middle cross beam and rear cross beam with respective cross-sectional shapes, to the subrack of different width dimensions, can adopt the way block setting-in of different in width varying number to form.Way block adopts ABS plastic die casting to form, and resistance to wear is good, and elasticity is stronger, can guarantee to assemble the required precision of back to the subrack width dimensions.
With reference to Fig. 4, Fig. 5, Fig. 6 and Fig. 7, along its length a guide groove 20 is arranged at way block top, in order to plug-in unit to be installed.The homonymy at way block two ends respectively has a reference block 21, and three kinds of accurate width dimensions are arranged, and according to the width of subrack, can select the way block of different in width, varying number to make up.Respectively have one outwards and the opposite hook 18 of direction along reference block 21 Width two ends downsides, along its length a groove 19 is arranged at the way block bottom, is the extrusion process groove.Also respectively there is an outside and opposite hook 18 of direction at the groove two ends.During setting-in, hook 18 all is stuck in taking along last of crossbeam upper slot, and way block is fixed on the crossbeam.Way block forms with ABS plastic die casting.
With reference to Fig. 8, there is a groove 22 the front beam front portion, but in the locking device insertion groove of plug-in unit, the pin dogging of locking device groove take along 24 on, plug-in unit is fixed in the subrack.The lower edge of front surface has convex edge 23, makes unlikely being exposed at outside the subrack of subrack panel of installing after locking.One groove 25 is arranged at top, and when the way block setting-in, way block is risen to the bait and 18 just is stuck in and takes along on 24, and way block is fixed on the front beam.Respectively there is an installing hole 27 both sides of upper slot 25, with screw front beam and straight beam are fixed behind the tapping.The rear portion downside has a groove 26, in order to lay cover plate or base plate.Front beam aluminum alloy materials pultrusion.
With reference to Fig. 9, a groove 28 is arranged at middle cross beam top, and during the way block setting-in, way block is risen to the bait and is stuck in the taking along on 29 of groove, and way block is fixed on the middle cross beam.Respectively there is an installing hole 30 both sides of groove, attack with screw thread with screw middle cross beam and straight beam to be connected and fixed.Middle cross beam aluminum alloy materials pultrusion.
With reference to Figure 10, a groove 31 is arranged at rear cross beam top, and during the way block setting-in, way block is risen to the bait and is stuck in the taking along on 32 of groove, and way block is fixed on the rear cross beam.Respectively there is installing hole 34 both sides of upper slot, with screw rear cross beam and straight beam are connected and fixed behind the tapping.There is a groove 33 at the rear cross beam rear portion, in order to laying holder, but on holder the connector mounting support.Taking along 32 of rear groove can prevent that holder from deviating from.Rear cross beam aluminum alloy materials pultrusion.
To the subrack of various width dimensions, the width of the Insertion panel of packing into is on demand selected the way block combination of different in width, varying number, is arranged in order setting-in and goes in the subrack.During setting-in, one end of each way block is aimed at the upper slot of front beam or rear cross beam, the other end is aimed at the groove of middle cross beam, firmly press down, being hooked on the way block relies in the strain embedded groove under the pressure after, rely on elastic reset again, hook just is stuck in taking along last of groove, and way block is fixed on the crossbeam.
When plug-in unit is installed, the rotation plug-in unit is two locking devices up and down, make its pin parallel with the front beam front groove, aiming at lower limb in the printed board of plug-in unit up and down, the guide groove of way block pushes, contact with front beam until Insertion panel, then locking device is unclamped hand behind the half-twist again, because the elastic force of locking device medi-spring, its pin is stuck in taking along last of groove, and plug-in unit just is fixed in the subrack.
