With reference to Figure 10 A, 10B and 10C, in described example, one 400 ' in the back door has bolt lock mechanism 405, and it can be anchored on door top cover 200 and back door mount pad 15.Bolt lock mechanism 405 has the door handle 410 that can touch from the outside at back door 400 ', and has the cylinder lock 430 that door handle 410 is locked in off-position.Inboard at back door 400 ', door handle 410 are connected in can be with the lobe plate 415 of its rotation.One upper boom 420 is connected in an end of lobe plate 415, and a lower beam 425 and upper boom 420 are connected in the other end of lobe plate 415 on the contrary.Upper boom 420 extends up to top cover 200 from lobe plate 415 roughly vertically, and lower beam 425 extends downwardly into a mount pad 15 from lobe plate 415 roughly vertically.When in the closed position, upper boom 420 puts in the hole in the top cover 200 and lower beam 425 puts in the hole on the mount pad 15, thereby this back door is pinned.

In Figure 10 A, 10B and the described example of 10C, one 400 ' in the back door has bolt lock mechanism 405, and relative back door 400 " be maintained at off-position with the back door 400 ' overlap joint of bolt lock mechanism.Perhaps, be not the mode that adopts overlap joint, but make two

back doors

400 ' and 400 " all have a bolt lock mechanism 405.

In another example shown in Figure 10 D, 10E and the 10F, one 400 ' in the back door has bolt lock mechanism 405A, is used for door is fixed in top cover 200 and back door mount pad 15.Bolt lock mechanism 405A have can be from the back door the 400 ' outside door handle (not shown) of touching, and have the cylinder lock 430A that this door handle lock can be fixed on off-position.Inboard at back door 400 ', door handle are connected in can be with the lobe plate 415A of its rotation.One upper boom 420A is connected in the end of lobe plate 415A, and a lower beam 425A and upper boom 420A are connected in the other end of lobe plate 415A on the contrary.Upper boom 420A extends up to top cover 200 from lobe plate 415A roughly vertically, and lower beam 425A extends downwardly into a mount pad 15 from lobe plate 415A roughly vertically.When in the closed position, upper boom 420A puts in the hole in the top cover 200, and lower beam 425A puts in the hole in the mount pad 15, thereby keeps the back door to close.

Especially with reference to Figure 10 E and 10F, in an example shown,

back door

400 ', 400 " be still overlap joint with second 400 " be maintained in its closed position, yet also can provide second 400 " extra fixing additional structural features.In an example shown, lobe plate 415A has protruding from the pivot center of lobe plate 415A and is approximately perpendicular to the lock arm 416 of this pivot center, and back door 400 " having plate 460, this plate has the notch 465 that is configured to receivability lock arm 416.Plate 460 can be for example to be fixed in back door 400 by welding or screw " part that separates, perhaps plate 460 can with back door 400 " be configured as one.In addition, lock arm 416 can be shaped as towards the back door 400 " step shape, so that lock arm 416 is removed from network cabinet 10 inboards.This can reduce the danger that the cable or wire of 10 li of network cabinets was clamped or blocked to lock arm 416.

Can find out that from Figure 10 E when bolt lock mechanism 405A was shown in an open position, lock arm 416 stretched out and is not engaged in notch 465,

back door

400 ', 400 downwards " can be opened.On the contrary, can find out from Figure 10 F that when bolt lock mechanism 405A moved to off-position, lock arm 416 rotates until its approximate horizontal and be engaged in notch 465.When being in this position, back door 400 " by back door 400 ' overlap joint thereon and be engaged in notch 465 by lock arm 416 and be fixed.

With reference to Figure 11, in the back door 400 each can be connected in top cover 200 by hinge component (or claiming hinge assembly) 435 conductions of a spring-loaded, and this hinge component comprises body 440, joint pin (or claiming swivel pin) 445, release arm 455 and the spring 450 of substantial cylindrical.Body 440 is steel or other electric conducting material and the inner surface that is welded in back door 400.

Joint pin 445 is steel or other electric conducting material and is positioned in the body 440.Release arm 455 is roughly L shaped, it pass body 440 the end the hole and be screwed into joint pin 445 with screw thread.Spring 450 is positioned in the body 440 and pressurized between joint pin 445 and body 440.Spring 450 allows joint pin 445 joint pin 445 to retract from body 440 to extrapolation and when release arm 455 tension.Joint pin 445 stretches out from the end of body 440, pass back door 400 the top a hole and pass lining 260 on the top cover 200, there, joint pin 445 is connected in the threaded screw 255 of attacking of top cover 200 with conduction and contacts.

For screw 255 conductions are connected in top cover 200, the ground connection angle steel 245 of a conduction is welded in the inner surface of top cover 200, and will attack threaded screw 255 and be screwed into ground connection angle steel 245 and be screwed into the nut 250 that is welded in ground connection angle steel 245, thereby provide the combination between top cover 200 and the screw 255.

In order to install or pull down back door 400, can spur release arm 455 downwards, this action compresses spring 450 also is retracted in the body 440 joint pin 445.Be lower than when being in lining 260 at joint pin 445, just can install back door 400 in place or remove.In case it is in place that install at back door 400, release arm 455 is released and the spring 450 outside joint pins 445 that promote make it pass lining 260, until joint pin 445 contact screws 255.

In this example, when installing back door 400, the hinge component 435 of spring-loaded provides linkage (or claiming linkwork) and reliable grounding path is provided for back door 400.This allows to pull down back door 400 with need not to disconnect any earthing jumper.

With reference to Fig. 2 A and 2B, in this example, door mount pad 15 also has hole 18, and it inwardly arranges from lining 600, and lining 600 can hold for the fixing joint pin in the bottom at back door 300.Although Fig. 2 A and 2B express the door mount pad 15 for Qianmen 500, yet two door mount pads 15 are mutual Mirror Symmetries, and for the door mount pad 15 at back door 400 identical hole 18 is arranged.With reference to Fig. 4 A, 4B and 11, top cover 200 has hole 265, and it inwardly arranges from lining 260, and the joint pin 445 of the linkage 435 of lining 260 receivability spring-loaded.Door each hole 18 on the mount pad 15 is aimed on the top cover 200 corresponding hole 265 and is provided a placement mechanism for the back door 400 that has been removed at roughly vertical axis.

For example, as mentioned above, can be by downward pulling release arm 455, joint pin 445 is retracted and allow back door 400 perks and be removed and back door 400 is removed.Not to lean against the back door 400 that removes on the rack 10 or by on the wall or lean against on the miscellaneous equipment that may be bumped against or knock over, but place the back door 400 that removes with each

hole

18 and 265 on a mount pad 15 and the top cover 200.The back door 400 that removes for placement, can open relative back door, fixing joint pin on the bottom at the back door 400 that removes is inserted the hole 18 of the lining 600 at the most close back door of opening in the door mount pad 15, and by downward pulling release arm 455, the joint pin 445 of the linkage 435 of spring-loaded is inserted corresponding hole 265 on the top covers 200.

With reference to Figure 12 A, in this embodiment, Qianmen 500 is installed on the front of network cabinet 10, between top cover 200 and Qianmen mount pad 15.In an example shown, Qianmen 500 is steel plates of essentially rectangular, it can be atresia or get out some holes for attractive in appearance and circulation of air, this dual regracting hinge that is articulated in, this will describe in detail hereinafter, open on this Men Kecong left side or the right, thereby provide the complete access channel to left frame or right frame and vertical cable management conduit, and needn't pull down Qianmen 500.Perhaps, according to the requirement of certain applications, door that need not single double-strand chain, but with the door of discrete gate, simple chain door or any other form, and Qianmen 500 can be by any geometry, any material, any design forming.

With reference to Figure 12 A, in this example, Qianmen 500 has the bolt lock mechanism 505 of two work independent of one another on its ground of every side.Bolt lock mechanism 505 has door handle 510 (seeing Figure 19), lobe plate 515, upper boom 520 and lower beam 525, and in operation, bolt lock mechanism 505 is basic identical with above-mentioned bolt lock mechanism 405 for back door 400 (seeing Figure 10 B and 10C).Bolt lock mechanism 505 also has the cylinder lock 530 (as shown in Figure 19) that door handle 510 can be locked in off-position.

With reference to Figure 12 A, the corner of each top of 500 and bottom at the Qianmen (having four positions) is provided with a locking hinge assembly 535.Figure 12 B and 12D express the locking hinge assembly 535 on all bottom corner at Qianmen 500, and should be appreciated that the hinge component on all top corners is identical with hinge component on the bottom corner described herein.Figure 12 C expresses the back side of the locking hinge assembly shown in Figure 12 B.Each locking hinge assembly 535 comprises hinge component, comprises hinge lever (or claiming hinged lever) 540, hinged support (or claiming hinged support) 542, joint pin 545, interior lever stopper 555 and the block component that comprises interior lever stopper 555 and outer lever retainer 570.With regard to used here, interior lever stopper 555 is lever stopper of the most close joint pin 545, and outer lever retainer 570 is apart from joint pin 545 lever stopper farthest.

Hinged support 542 has roughly vertical wall 543, and it is fixed in Qianmen 500 by such as welding, screw etc., and the wall 544 of approximate horizontal, and it roughly vertically extends with it from the top of vertical walls 543.Hinge lever 540 by pin 560 be installed on hinged support 542 vertical walls 543 so that hinge lever 540 rotate around pin 560.Hinge lever 540 also is connected in rotationally lower beam 525 (or upper boom 520, which locking hinge assembly this depends on) and itself and lower beam 525 relative places, end with the one end and is connected in joint pin 545.Joint pin 545 extends through Qianmen 500 roughly vertically and passes horizontal wall 544.

As shown in Figure 12 C, a lever stop hinge pin 550 is fixed in Qianmen 500, and lever stopper 555,570 is installed on the lever stop hinge pin 550, so that lever stopper 555,570 can be rotated around joint pin 550.Each lever stopper 555,570 has roughly vertical stopper arms 556,571 and the release arm 557,572 of approximate horizontal.A torque spring 565 or other elastic component are installed on the lever stop hinge pin 550, and have and outwards stretch to lever stopper 555,570 stopper arms 556,571 lever stopper 555,570 is pressed onto two ends of an anteposition.

In use, in the time will closing Qianmen 500 (two bottom corner that off-position is defined as two top corner at the Qianmen 500 that falls to leaning against on the top cover 200 and falls to leaning against the Qianmen 500 on the mount pad 15), upper boom and lower beam 520 and 525 are pulled to the central authorities at Qianmen 500, thus pivot lever arm 540 and make all joint pins 545 put in the lining 600 corresponding with them on a mount pad 15 or the top cover 200.So the joint pin 545 in each in four bights at Qianmen 500 is engaged in the lining 600 in a mount pad 15 or the top cover 200, Qianmen 500 is pinned fully like this.In addition, when off-position, door mount pad 15 or top cover 200 will promote two lever stopper 555,570 release arm 557,572, thereby make lever stopper 555,570 stopper arms 556, the rotation path of 571 disengaging hinge levers 540.This allows hinge lever 540 freely to rotate to either direction.With reference to Figure 12 B, when forwarding door handle to open position from off-position, lower beam 525 descends especially, and hinge lever 540 rotates around bearing pin 560, and joint pin 545 is retracted.This makes Qianmen 500 pivotally open around the opposition side joint pin 545 that keeps stretching out.On the contrary, (for example door handle is pulled off-position from open position) when lower beam 525 is lifted, hinge lever 540 will and stretch out joint pin 545 around pin 560 rotations.

Especially with reference to Figure 12 B and 12D, it is expressed when the left side at Qianmen and unlocks and the work of Qianmen (in the face of watching in the front of network cabinet 10) locking hinge assembly 535 when being opened from left to right, as shown in Figure 12 A.Figure 12 B expresses when Qianmen 500 and still keeps the work of locking hinge assembly 535 on that side of engagement (joint pin 545 stretches out), and Figure 12 D expresses the work of the locking hinge assembly 535 on that side of having thrown off at Qianmen 500.

With reference to Figure 12 B, when Qianmen 500 moved apart off-position, door mount pad 15 no longer pushed lever stopper 555,570 release arm 557,572, and torque spring 565 tries hard to lever stopper 555,570 is shifted onto anteposition.Because hinge lever 540 still is in locked position, interior lever stopper 555 is hindered by hinge lever 540 and can not rotate forward.Yet outer lever retainer 570 is not subjected to the obstruction of hinge lever 540 and is shifted onto anteposition by torque spring 565.When lever stopper 570 is in anteposition outside, stopper arms 571 be positioned at hinge lever 540 below, stop thus hinge lever 540 to rotate.So in this position, if the user attempts switching door handle (attempting to make lower beam 525 to move down), stopper arms 571 will stop hinge lever 540 to rotate, and stop thus door handle to be pulled.If the hinge of opposite side is thrown off and Qianmen 500 is opened, this can prevent that the hinge that meshes from unexpectedly being thrown off.If can not prevent this unexpected disengagement, Qianmen 500 is injured with regard to being easy to come off and is stood in network cabinet 10 outrunners.

With reference to Figure 12 D, for Qianmen 500 is removed from off-position, the locking hinge assembly 535 on the side that be opened is thrown off.When user's switching door handle, lower beam 525 is pushed down, and this action rotates hinge lever 540 and to the moving joint pin 545 of pulling back.Thrown off and after Qianmen 500 moved apart off-position at locking hinge assembly 535, door mount pad 15 no longer pushes lever stopper 555,570 release arm 557,572, and torque spring 565 tries hard to lever stopper 555,570 is shifted onto anteposition.Because hinge lever 540 has moved apart locked position, outer lever retainer 570 is subjected to the obstruction of hinge lever 540 and can not rotates forward.Yet interior lever stopper 555 is not subjected to the obstruction of hinge lever 540 and is shifted onto anteposition by torque spring 565.When interior lever stopper 555 is in anteposition, stopper arms 556 be positioned at hinge lever 540 below, stop thus hinge lever 540 to rotate.So in this position, if the user attempts switching door handle (attempting to make lower beam 525 to move up), stopper arms 556 will stop hinge lever 540 to rotate, and stop thus door handle to be pulled.This will stop door handle to be closed, until Qianmen 500 is in complete off-position, so that lever stopper 555 has been pushed rearward, thereby do not hinder hinge lever 540 to allow joint pins 545 to be pushed down and will pass and mesh fully lining 600.

It can be seen from the above, and before, locking hinge assembly 535 requires Qianmen 500 in the closed position can to change the state (for example make locking hinge assembly 535 engagement or throw off) at Qianmen 500 the user.Can reach so such two free-revving engines: (1) can prevent the unexpected of Qianmen 500 or come off unexpectedly (be when opening in a side, opposite side is lockable and can not throws off, until Qianmen 500 is closed); And (2) can prevent that the user 500 is still and thinks that mistakenly it is (until Qianmen 500 is fully closed and lever stopper allows the hinge lever to move, door handle can not be moved to off-position) of closing when half-open at the Qianmen.

In order to pull down Qianmen 500, at first make Qianmen 500 place off-position.In this position, the whole inside and outside lever stopper 555,570 of all locking hinge assemblies 535 is pulled to retracted position, thereby allows hinge lever 540 to move freely.When being in off-position, pull two door handles, these two door handles throw off all locking hinge assemblies 535 by upper boom and lower beam 520,525 being extended and each joint pin 545 being retracted from lining 260,600 separately, and this allows to pull down Qianmen 500.In case Qianmen 500 has been removed, all interior lever stopper 555 are moved to their anteposition by torque spring 565, thereby hinder hinge lever 540 and then stop two door handles to be pulled.For Qianmen 500 is installed, can carry out conversely said process.Qianmen 500 is leaned against on a mount pad 15 and the top cover 200, make each joint pin 545 aim at their linings 260,600 separately.In this position, door mount pad 15 and top cover 200 will promote interior lever stopper 555 backward and make it not hinder hinge lever 540, thus allow hinge lever 540 freely to rotate.Right latter two door handle is pulled and upper boom and lower beam 520,525 is retracted, and therefore makes each joint pin 545 put in each corresponding lining 260,600.

With reference to Figure 12 E, it expresses the joint pin 545 at Qianmen 500 and the engagement between the door mount pad 15.Joint pin 545 passes and is engaged in the lining 600 in the hole of the end face that is positioned at a mount pad 15.In this example, promote screw 605 and be screwed into the just bottom of the door mount pad 15 below the lining 600 that is engaged in joint pin 545 with screw thread.Along with door handle is pulled off-position, joint pin 545 moves down and passes lining 600 and contact lifting screw 605.After joint pin 545 contacts promoted screw 605, joint pin 545 continued to move down and lifting Qianmen 500 makes it to leave lining 600.So Qianmen 500 is on joint pin 545, this can provide also sinking and/or the stack of the tolerance limit under the worst case of compensation door of the gap between Qianmen 500 and the door mount pad 15 when closing Qianmen 500.

In above-mentioned example, the weight (rather than on lining 600) by the Qianmen 500 on joint pin 545 has a constant force to act on the joint pin 545, and this power attempts to shift joint pin 545 onto retracted position.If fully engagement of door handle when Qianmen 500 is in the closed position, the power on the joint pin 545 of acting on may make door handle rotate and locking hinge assembly 535 is thrown off to open position.In order to prevent this situation, can adopt a kind of super cam (overcam) bolt lock mechanism.With reference to Figure 12 F and 12G, the substantially the same place in above-mentioned bolt lock mechanism 505 of the super cam latch 505A of mechanism is: upper boom and lower beam 520,525 that it has the door handle (not shown), is connected in the lobe plate 515A of door handle and is connected in the protruding wide part of lobe plate 515A.The main distinction between bolt lock mechanism 505 and the super cam latch 505A of mechanism is the project organization of lobe plate 515A.The all protruding wide part of the lobe plate 515 in the bolt lock mechanism 505 is alignment and protruding from the pivot center of lobe plate 515.On the contrary, the lobe plate 515A among the super cam latch 505A of mechanism has roughly mutually perpendicular and from the outwardly directed protruding wide part 517 of the pivot center of lobe plate 515A, 518.

Can be clear that from Figure 12 G, when 500 in the closed position and each locking hinge assembly 535 are in engagement at the Qianmen, be connected in the basically vertical extension of protruding wide part 517 of lower beam 525 (and then being connected in underneath hinges pin 545).At work, the power (such as the weight at the Qianmen 500 on joint pin 545) of attempting joint pin 545 is retracted that acts on underneath hinges pin 545 is used in a downward masterpiece on the lower beam 525.But because that protruding wide part 517 is in is vertical, this acts on downward power on the lower beam 525 can not make lobe plate 515A (and then making door handle) rotate.In order turning the handle and lobe plate 515A, must to apply an effective rotatory force to door handle and make protruding wide part 517 leave the vertical position.This project organization can prevent that lobe plate 515A and door handle are owing to the power that the weight at Qianmen 500 acts on underneath hinges pin 545 is rotated.

With reference to Figure 13, in this embodiment, Qianmen 500 is connected in top cover 200 by bearing assembly 610 conductions of spring-loaded.The bearing assembly 610 of two spring-loaded is positioned to be installed on the one hand two opposite bights of top cover 200, on the one hand near each lining 600 and joint pin 545.The bearing assembly 610 of spring-loaded being positioned near in the situation of joint pin 545, be rocked in the process of open position at Qianmen 500, bearing assembly 610 keeps contacting with Qianmen 500.By adopting two bearing assemblies 610, Qianmen 500 is being closed, all with top cover 200 is being kept combination when opening or opening left to the right.The bearing assembly 610 of each spring-loaded has body 615, ball bearing 620, panel 625 and the spring 630 of substantial cylindrical.Body 615 is that steel or other electric conducting material are made and has and allow body 615 to be screwed on the top cover 200 external screw thread of the corresponding internal thread that paint not hides, until steel panel 625 is concordant with top cover 200, this can set up the bearing assembly 610 of spring-loaded and the combination between the top cover 200.Ball bearing 620 is that steel or other electric conducting material are made, thereby its spring that is conducted electricity 630 is pressed to panel 625 and projection exceeds the end face that contacts Qianmen 500 outside the panel 625.The place that contacts with ball bearing 620 on the end face at Qianmen 500 is covered, and this provides the combination between bearing assembly 610 and the Qianmen 500.Bearing assembly is fixed to be become close enough lining 600 and a joint pin 545 by the position, so that Qianmen 500 can be opened to about 160 degree and still can keep combination between Qianmen 500 and the top cover 200.The combination of setting up between Qianmen 500 and the top cover 200 with bearing assembly 610 allows to pull down Qianmen 500, and needn't disconnect any jumper.

Perhaps, can find out from Figure 12 B and 12E, not that bearing assembly 610 by the spring-loaded on the top cover 200 makes Qianmen 500 conductions be connected in main frame 100, but Qianmen 500 can be connected in main frame 100 by lifting screw 605 conductions on the door mount pad 15.In conjunction with Qianmen 500, at first make lifting screw 605 conductions be connected in a mount pad 15 for by this way.This can by promote with three wings screw, with internal tooth lock washer place promote between screw head and the door mount pad or with the toothed lifting screw of head downside or not the opposite house mount pad with promote that a part of coating that head of screw contact and paint and realize.Then, for example by jumper being fixed between joint pin 545 and the Qianmen 500, joint pin 545 is connected in Qianmen 500 by conduction.So, when joint pin 545 contact promotes screw 605, by jumper, joint pin 545 with promote screw 605 and set up combination between Qianmen 500 and the door mount pad 15.

Can find out that from above detailed description in this embodiment, when network cabinet 10 assembled up fully, all parts of this rack had all combined.Consist of each member all combinations by welding together of main frame 100.Door mount pad 15, equipment guide rail 20 and top cover 200 are by adopting the internal tooth lock washer conduction to be connected in main frame 100.Side plate 300 is by adopting earth clip 335 conductions to be connected in top cover 200.Back door 400 is grounded on top cover 200 by the ground connection linkage 435 of spring-loaded.At last, Qianmen 500 is grounded on top cover 200 by the bearing assembly 610 of spring-loaded.Combine by all parts rack, just do not need independent earthing jumper, so network cabinet 10 can dead ground and only need to get final product with a contact point (for example ground outlet 25) of main constructure ground.

With reference to Figure 14 A, network cabinet 10 can comprise that also self-alignment castor assembly 700, cable management refer to structure 800 and lax management mandrel 900.

With reference to Figure 14 A and 14B, in this example, self-alignment castor assembly 700 is installed in forward and backward vertical frame guide rail 105,110 side, and this is in order to install, to reduce when pulling down or repairing self-alignment castor assembly 700 network cabinet 10 or main frame 100 perks or the needs that fell.Self-alignment castor assembly 700 comprises body 705, it is that steel or other electric conducting material are made, it comprises the first wall 710, is approximately perpendicular to the second wall 715 and a pair of abutment wall 720 of fixation wall 710, and described abutment wall 720 extends between the first wall 710 and the second wall 715 and provides strength and stiffness for body 705.
