In the example described in Figure 10 A, 10B and 10C, there is bolt lock mechanism 405 at one of back door 400 ', and relative back door 400 " there is the back door 400 ' overlap joint of bolt lock mechanism and be maintained at off-position.Or, the mode that need not overlap, but back door 400 ' and 400 " all load onto bolt lock mechanism 405.

In another example shown in Figure 10 D, 10E and 10F, there is bolt lock mechanism 405A at one of back door 400 ', and it can be this door lock in top cover 200 and back door mount pad 15.Bolt lock mechanism 405A has the door handle (not shown) that can touch from the outside at back door 400 ', and also can have can be this door handle lock the cylinder lock 430A in off-position.In the inner side at back door 400 ', door handle is connected in can be with the lobe plate 415A of its rotation.A upper boom 420A is connected in one end of lobe plate 415A, and lower beam 425A is connected in the other end of

lobe plate

415A, and 420A is contrary with upper boom.Upper boom 420A generally perpendicularly extends up to top cover 200 from lobe plate 415A, and lower beam 425A generally perpendicularly extends downwardly into a mount pad 15 from lobe plate 415A.Time in the closed position, upper boom 420A puts in a hole on top cover 200, and lower beam 425A puts in a hole on a mount pad 15, thereby this back door is pinned.

Especially with reference to Figure 10 E and 10F, in an example shown, back door 400 ', 400 " be still overlap joint and second door 400 " be maintained in its closed position, can provide second door 400 but also can have " the additional structure of further pinning.In an example shown, lobe plate 415A has protruding and is approximately perpendicular to the locking cam 416 of the pivot center of lobe plate 415A and back door 400 " there is a plate 460, this plate has the notch 465 that is configured to receivability locking cam 416.Plate 460 can be a part separating, and use such as welding or screw be fixed on back door 400 ", or plate 460 can with back door 400 " be configured as one.In addition, locking cam 416 can be shaped as towards back door 400 " step shape, so that locking cam 416 is removed from the inner side of network cabinet 10.This can reduce locking cam 416 clamps or blocks the danger of the cable or wire of 10 li of network cabinets.

Can find out from Figure 10 E, in the time that bolt lock mechanism 405A is in an open position, locking cam 416 is stretched downwards and is not engaged in notch 465, back door 400 ', 400 " can be opened.On the contrary, can find out from Figure 10 F, in the time that bolt lock mechanism 405A is moved to off-position, locking cam 416 rotates until it becomes approximate horizontal and is engaged in notch 465.When in this position, back door 400 " closed thereon and be lockable because locking cam 416 is engaged in notch 465 by back door 400 ' overlap joint.

With reference to Figure 11, each in back door 400 can be conducted electricity and is connected in top cover 200 by the hinge component of a spring-loaded 435, and this hinge component comprises body 440, joint pin 445, release arm 455 and the spring 450 of substantial cylindrical.Body 440 is steel or other electric conducting material and is welded in the inner surface at back door 400.Joint pin 445 is steel or other electric conducting material and is positioned in body 440.Release arm 455 is roughly L shaped, through the hole of the end of body 440 and be screwed into joint pin 445 with screw thread.Spring 450 is positioned in body 440 and is compressed between joint pin 445 and body 440.Spring 450 joint pin 445 from body 440 to extrapolation and in the time that release arm 455 is drawn, allow joint pin 445 return come.Joint pin 445 stretches out from the end of body 440, and through hole at the top at back door 400 and through the lining 260 on top cover 200, there, joint pin 445 contact conductions are connected in the screw 255 of top cover 200.

For screw 255 conductions are connected in to top cover 200, the ground connection angle steel 245 of a conduction is welded in to the inner surface of top cover 200, and screw 255 is screwed into ground connection angle steel 245 and is screwed into the nut 250 that is welded in ground connection angle steel 245, thereby the conduction of setting up between top cover 200 and screw 255 connects.

In order to install or pull down back door 400, can pull down release arm 455, its Compress Spring 450 also makes joint pin 445 return to 440 li of bodies.Below height at joint pin 445 in lining 260 time, just back door 400 can be installed in place or removed.Once it is in place that install at back door 400, release arm 455 is just released, and spring 450 is to extrapolation joint pin 445 through lining 260, until joint pin 445 contact screws 255.

In this example, in the time installing back door 400, the hinge component 435 of spring-loaded provides linkage and reliable grounding path is also provided to back door 400.This allows to pull down back door 400 and without untiing any ground connection cross-over connection wire.

With reference to Fig. 2 A and 2B, in this example, door mount pad 15 is also porose 18, and it inwardly arranges from lining 600, and lining 600 receivabilities are used for the fixing joint pin in bottom at back door 300.Although it is mutual Mirror Symmetries that Fig. 2 A and 2B express for 15, two door mount pads 15 of door mount pad at Qianmen 500, and there is identical hole 18 for the door mount pad 15 at back door 400.With reference to Fig. 4 A, 4B and 11, top cover 200 is porose 265, and it inwardly arranges from lining 260, and the joint pin 445 of the linkage 435 of lining 260 receivability spring-loaded.Each hole 18 on each mount pad 15 is aimed at corresponding hole 265 on top cover 200 and is provided one to place mechanism for the back door 400 being removed on substantially vertical axis.

For example, as mentioned above, can be by pulling down release arm 455, it returns joint pin 445 and allows to make back door 400 to tilt, and back door 400 can be removed.Needn't the back door 400 removing be leaned against on rack 10 or lean against on wall or lean against on the miscellaneous equipment that may be knocked or knock over, but can place the back door 400 removing with each

hole

18 and 265 on door mount pad 15 and top cover 200.For placing the back door 400 removing, relative back door can be opened, the hole 18 of the lining 600 at the most close back door of opening on the fixing joint pin inserting door mount pad 15 on the bottom at the back door 400 removing, and by pulling down release arm 455, the joint pin 445 of the linkage 435 of spring-loaded is injected to the corresponding hole 265 on top cover 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 rectangular steel plates roughly, its can be atresia or get out some holes for attractive in appearance and circulation of air, this door is hinged at bilateral with two telescopic hinges, this will below describe in detail, this door can by from the left side or the right open, thereby open wide the path that can approach left or right bar frame and vertical cable management conduit, and needn't pull down Qianmen 500.Or, according to the requirement of certain applications, door that need not single double-strand chain, but can be with door, the door of simple chain or the door of any other pattern of amalgamation, and any geometry can be made in Qianmen 500, with any material manufacture, make any version.

With reference to Figure 12 A, in this example, there are two bolt lock mechanisms 505 at Qianmen 500, and one of each side at Qianmen 500, they operate independently of one another.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 the above-mentioned bolt lock mechanism 405 for back door 400 (seeing Figure 10 B and 10C).Bolt lock mechanism 505 also can have the cylinder lock 530 (as shown in Figure 19) that door handle 510 can be locked in to off-position.

With reference to Figure 12 A, there is a locking hinge assembly 535 in each top corners and the bottom corner (having four positions) at Qianmen 500.Figure 12 B and 12D express the locking hinge assembly 535 in two bottom corner at Qianmen 500, will be understood that two hinge components in top corners are identical with the hinge component in bottom corner described herein.Figure 12 C expresses the back side of the bolt lock mechanism shown in Figure 12 B.Each locking hinge assembly 535 comprises hinge lever 540, hinge bracket 542, joint pin 545, 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.

Hinge bracket 542 has substantially vertical wall 543, and it is by being fixed on Qianmen 500 such as welding, screw etc., and the wall 544 of an approximate horizontal, and roughly vertically extend with it on its top from vertical wall 543.Hinge lever 540 is installed on the vertical wall 543 of hinge bracket 542 by bearing pin 560, hinge lever 540 can be rotated around bearing pin 560.Hinge lever 540 is also connected in rotationally lower beam 525 (or upper boom 520, this according to be which locking hinge assembly) and is connected in joint pin 545 with its other end with its one end.Joint pin 545 generally perpendicularly extends through Qianmen 500 and passes horizontal wall 544.

As shown in Figure 12 C, a lever stop hinge pin 550 is fixed on Qianmen 500, and lever stopper 555,570 is arranged on lever stop hinge pin 550, and lever stopper 555,570 can be rotated around joint pin 550.Each lever stopper 555,570 has respectively the release arm 557,572 of substantially vertical stopper arms 556,571 and approximate horizontal.A torque spring 565 is arranged on lever stop hinge pin 550, and its two ends are stretched to the stopper arms 556,571 of lever stopper 555,570 and lever stopper 555,570 is pressed onto to an anteposition.

In use, in the time will closing Qianmen 500 (two top corners that off-position is defined as Qianmen 500 lean against on top cover 200 and two bottom corner at Qianmen 500 lean against on a mount pad 15), upper boom and lower beam 520 and 525 are pulled to the central authorities at Qianmen 500, so as to turning joint lever 540 and make each joint pin 545 put in the each lining 600 corresponding with them on a mount pad 15 or top cover 200.So the joint pin 545 in each in four bights at Qianmen 500 is engaged in the corresponding lining 600 on a mount pad 15 or top cover 200, Qianmen 500 will be pinned completely like this.In addition, in the time of off-position, door mount pad 15 or top cover 200 will promote the release arm 557,572 of two lever stopper 555,570, thereby make the stopper arms 556,571 of lever stopper 555,570 depart from hinge lever 540.This will allow hinge lever 540 freely to rotate to either direction.With reference to Figure 12 B, in the time that door handle is forwarded to open position from off-position, lower beam 525 is pushed down especially, and hinge lever 540 rotates counterclockwise around bearing pin 560, and joint pin 545 is contracted.This turns joint pin 545 hinges that Qianmen 500 stretches out around the maintenance of opposition side to open.On the contrary, for example, in the time that lower beam 525 is lifted (door handle is pulled off-position from open position), hinge lever 540 will clockwise rotate and stretch out joint pin 545 around bearing pin 560.

Especially with reference to Figure 12 B and 12D, it has expressed at the left side opening at Qianmen the work of lock and Qianmen (in the face of watching in the front of network cabinet 10) locking hinge assembly 535 while being opened from left to right, as shown in Figure 12 A.Figure 12 B expresses the work at the locking hinge assembly 535 of that side that is still engaging (joint pin 545 stretches out) at Qianmen 500, and Figure 12 D expresses the work of the locking hinge assembly 535 of that side of the disengagement (joint pin 545 is retracted) at Qianmen 500.

With reference to Figure 12 B, while movement from off-position at Qianmen 500, door mount pad 15 no longer pushes the release arm 557,572 of lever stopper 555,570, and torque spring tries hard to lever stopper 555,570 to shift anteposition onto.Because hinge lever 540 is still being lockable position, interior lever stopper 555 is hindered by hinge lever 540 and can not rotate forward.But outer lever retainer 570 is not subject to the obstruction of hinge lever 540 and is shifted onto anteposition by torque spring 565.Lever stopper 570 is in the time of anteposition outside, and stopper arms 571 is positioned at below hinge lever 540, thereby stops hinge lever 540 to rotate.So in this position, if user attempts switching door handle (attempting to make lower beam 525 to move down), stopper arms 571 will stop hinge lever 540 to rotate, thereby stop door handle to be pulled.If the hinge of opposite side has been departed from and Qianmen 500 has been opened, this hinge that can prevent engagement is unexpectedly departed from.If can not prevent this unexpected disengaging, Qianmen 500 is just easy to come off and injures and stands in network cabinet 10 outrunners.

With reference to Figure 12 D, for Qianmen 500 is removed from off-position, must make the locking hinge assembly 535 being opened in this side depart from.In the time of user's switching door handle, lower beam 525 is pushed downwards, and it will make hinge lever 540 rotate and to the joint pin 545 of pulling back.Depart from and after Qianmen 500 moved apart off-position, door mount pad 15 no longer pushes the release arm 557,572 of lever stopper 555,570, and torque spring 565 tries hard to lever stopper 555,570 to shift anteposition onto at locking hinge assembly 535.Because hinge lever 540 has been moved apart locked position, outer lever retainer 570 is subject to stopping of hinge lever 540 and can not rotates forward.But interior lever stopper 555 is not subject to the obstruction of hinge lever 540 and is shifted onto anteposition by torque spring 565.In interior lever stopper 555, during in anteposition, stopper arms 556 is positioned at below hinge lever 540, thereby stops hinge lever 540 to rotate.So in this position, if user attempts switching door handle (attempting to make lower beam 525 to move up), stopper arms 556 will stop hinge lever 540 to rotate, thereby stop door handle to be pulled.This closes prevention door handle, until Qianmen 500 in complete off-position, makes lever stopper 555 be pushed rearward, thereby does not hinder hinge lever 540 to allow joint pin 545 to be pushed downwards and engages lining 600 completely.

As can be seen from the above, before, locking hinge assembly 535 requires Qianmen 500 in the closed position to the state (for example making locking hinge assembly 535 engage or depart from) that can change Qianmen 500 user.This can reach such two free-revving engines: (1) can prevent the unexpected of Qianmen 500 or come off unexpectedly (be while opening in a side, opposite side is lockable and can not be departed from, until Qianmen 500 is closed); And (2) can prevent that user is still at Qianmen 500 and think mistakenly that it is to have closed (be fully closed at Qianmen 500 and before lever stopper allows hinge lever motion, door handle can not be moved to off-position) when half-open.

In order to pull down Qianmen 500, first Qianmen 500 is placed on to off-position.In this position, the whole interior and outer lever retainer 555,570 of locking hinge assembly 535 is pulled to retracted position, and allows hinge lever 540 freely to rotate.In the time being in this off-position, pull two door handles, these two door handles are by by making upper boom and lower beam 520,525 and make each joint pin 545 stretch out and return from lining 260,600 separately respectively that all locking hinge assemblies 535 are departed from, and this just allows to pull down Qianmen 500.Once Qianmen 500 has been removed, each interior lever stopper 555 is just shifted onto their anteposition by torque spring 565, thereby hinders 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 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 make it not hinder hinge lever 540 to lever stopper in pusher 555, thereby allow hinge lever 540 freely to rotate.So two door handles can be pulled and upper boom and lower beam 520,525 are return, thereby and make each joint pin 545 put in each self-corresponding lining 260,600.

With reference to Figure 12 E, it expresses joint pin 545 and the engagement of door between mount pad 15 at Qianmen 500.Joint pin 545 stretches out and is engaged in the lining 600 in the hole on the end face that is positioned at a mount pad 15.In this example, promote screw 605 and be screwed into just in the bottom that is engaged in the door mount pad 15 under the lining 600 of joint pin 545 with screw thread.Along with door handle is pulled off-position, joint pin 545 moves downward through lining 600 contact and promotes screw 605.After joint pin 545 contact promotes screws 605, joint pin 545 continues to move downward and promotes Qianmen 500 and leaves lining 600.So Qianmen 500 is being supported by joint pin 545, this can provide the tolerance accumulation under sinking and/or the worst case of gap between mount pad 15 of Qianmen 500 and door compensation door in the time closing Qianmen 500.

In above-mentioned example, in the time that the weight at Qianmen 500 is being supported by joint pin 545 (instead of being bearing on lining 600), there is a constant masterpiece to be used on joint pin 545 and try hard to joint pin 545 to shift retracted position onto.If not engagement completely of door handle time in the closed position at Qianmen 500, this power acting on joint pin 545 may make door handle rotate and may make locking hinge assembly 535 throw off to open position.In order to prevent this situation, can adopt a kind of overhead cam (overcam) bolt lock mechanism.With reference to Figure 12 F and 12G, overhead cam bolt lock mechanism 505A is substantially the same in above-mentioned bolt lock mechanism 505, and overhead cam bolt lock mechanism 505A has door handle (not shown), is connected in the lobe plate 515A of door handle and is connected in upper boom and the lower beam 520,525 of the protruding wide part of lobe plate 515A.The main distinction between bolt lock mechanism 505 and overhead cam bolt lock mechanism 505A is the project organization of lobe plate 515A.The protruding wide part of the lobe plate 515 that bolt lock mechanism is 505 li is alignment and protruding from the pivot center of lobe plate 515.On the contrary, two the protruding wide parts the 517, the 518th of the lobe plate 515A in overhead cam bolt lock mechanism 505A, roughly mutually perpendicular and protruding from the pivot center of lobe plate 515A.

Can be clear that from Figure 12 G, at Qianmen 500 in the closed position and each locking hinge assembly 535 be engagement time, protruding wide part 517 perpendicular that are connected in lower beam 525 (and then underneath hinges pin 545) are extended.At work, act on the power (such as the weight at the Qianmen 500 of being supported by joint pin 545) that trying hard on underneath hinges pin 545 return joint pin 545 and will make downward acting on lower beam 525.But because protruding wide part 517 is to be in vertically, this downward power acting on lower beam 525 can not make lobe plate 515A (and then 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 upright position.This project organization can prevent that lobe plate 515A and door handle are because 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 also conducted electricity and is connected in top cover 200 by the bearing assembly 610 of spring-loaded.The bearing assembly 610 of two spring-loaded is positioned to be arranged on respectively two contrary bights of top cover 200, near each lining 600 and joint pin 545.The bearing assembly 610 of spring-loaded being orientated as near in the situation of joint pin 545, be swung in an open position process at Qianmen 500, the bearing assembly 610 of spring-loaded keeps contacting with Qianmen 500.By adopting the bearing assembly 610 of two spring-loaded, Qianmen 500 all keeps conduction to be connected in top cover 200 left to the right in the time closing, open or open.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 steel or other electric conducting material and has the external screw thread that can be screwed into the corresponding internal thread that does not paint covering on top cover 200, and be screwed into panel 625 always and contact the surface of top cover 200, this conduction that can set up between bearing assembly 610 and the top cover 200 of spring-loaded connects.Ball bearing 620 be steel or other electric conducting material, thereby its spring 630 by electric conducting material presses to panel 625 and projection exceeds outside panel 625 until the end face at contact Qianmen 500.On the end face at Qianmen 500, the place that ball bearing 620 contacts does not have skin of paint, and this conduction that can set up between bearing assembly 610 and the Qianmen 500 of spring-loaded connects.Bearing assembly is positioned to enough close lining 600 and joint pin 545, makes Qianmen 500 can be opened to approximately 160 degree and still can keep the conduction between Qianmen 500 and top cover 200 to connect.Set up conduction between Qianmen 500 and top cover 200 with the bearing assembly 610 of spring-loaded and connect and allow to pull down Qianmen 500, and needn't disconnect any cross-over connection wire.

Or, can find out from Figure 12 B and 12E, the conduction of main frame 100 is connected by the bearing assembly 610 of the spring-loaded on top cover 200 without Qianmen 500, and can allow Qianmen 500 be connected in main frame 100 by lifting screw 605 conductions on door mount pad 15.To connect Qianmen 500 in order conducting electricity by this way, to be first connected in a mount pad 15 promoting screw 605 conductions.Its practice is, with a trigonodont lifting screw, an internal tooth lock washer is placed between the head and door mount pad that promotes screw, or has the lifting screw of tooth with a head of screw lower surface, or allow that part contact of not painting of a mount pad promote the head of screw.Then,, by such as cross-over connection wire being fixed between joint pin 545 and Qianmen 500, joint pin 545 conductions are connected in to Qianmen 500.So in the time that joint pin 545 contacts promote screw 605, the conduction of just having set up between Qianmen 500 and door mount pad 15 by cross-over connection wire, joint pin 545 and lifting screw 605 connects.

Can find out from above detailed description, in this embodiment, in the time that network cabinet 10 assembles up completely, all parts of this rack all conduct electricity and have coupled together.Each member that forms main frame 100 all conducts electricity and has connected by welding together.Door mount pad 15, equipment guide rail 20 and top cover 200 are by adopting 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.Finally, Qianmen 500 is grounded on top cover 200 by the bearing assembly 610 of spring-loaded.All conduct electricity and couple together by all parts this rack, just do not need each independent ground connection cross-over connection wire, network cabinet 10 can dead ground, only needs a single points (for example ground outlet 25) conduction to be connected in the ground connection facility of main building.

With reference to Figure 14 A, network cabinet 10 also can comprise castor assembly 700, cable management finger 800 and lax management mandrel 900.

With reference to Figure 14 A and 14B, in this example, castor assembly 700 is mounted in the side of front and rear vertical frame guide rail 105,110, and this is in order network cabinet 10 or main frame 100 to be tilted or to fall in the time installing, pull down or repair castor assembly 700.Castor assembly 700 comprises body 705, it be steel or other electric conducting material, it comprises the first wall 710, is approximately perpendicular to the second wall 715 and a pair of abutment wall 720 of the first wall 710, and the latter extends between the first wall 710 and the second wall 715 and provides strength and stiffness to body 705.

The castor wheel 730 of standard is connected in the second wall 715 of body 705.The first wall 710 of body 705 has pair of holes 711 and a wall member 712, and the latter stretches out and forms the groove 713 between wall member 712 and the first wall 710 from the first wall 710.

As shown in Figure 14 B, for installation foot wheel assembly 700, can raise main frame 100 by rotating leveling leg 60.The first wall 710 of castor assembly 700 is leaned against on rear vertical frame guide rail 110, make wall member 712 put in the hole 111 on rear vertical frame guide rail 110.Then, the castor assembly 700 of loweing, makes the tab 112 of the 111 li of formation in hole be engaged in the groove 713 forming between wall member 712 and the first wall 710, and makes each hole 711 on the first wall 710 aim at each hole 113 being formed on rear vertical frame guide rail 110.Inserted the hole 113 on hole 711 and the rear vertical frame guide rail 110 on the first wall 710 and be screwed into the stop nut 114 being welded on rear vertical frame guide rail 110 by pair of bolts 725.Then, by rotate leveling leg 60 lower main frame 100 until main frame 100 supported by castor assembly 700.Except castor assembly 700 being fixed on rear vertical frame guide rail 110, the conduction that each bolt 725 and stop nut 114 also can be set up between castor assembly 700 and rear vertical frame guide rail 110 connects.Connect in order to set up this conduction, the bolt head lower surface of bolt 725 can have can break any skin of paint by the teeth and sting into sawtooth or the tooth of the metal of body 705, and this just can set up conduction connection between body 705 and bolt 725.Or, if need conduction to connect, can be used together standard bolt and internal tooth lock washer and set up conduction and is connected, or with standard bolt and make region around, hole 711 not have skin of paint to set up conduction connection.
