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

In another example shown in Figure 10 D, 10E and the 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 the cylinder lock 430A that can be locked in this door handle off-position also can be arranged.Inboard at back door 400 ', door handle are connected in can be with the lobe plate 415A of its rotation.A upper boom 420A is connected in the end of lobe plate 415A, and lower beam 425A is connected in the other end of lobe plate 415A, and 420A is opposite 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.When in the closed position, upper boom 420A puts in the hole on the top cover 200, and lower beam 425A puts in the hole on the 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 " plate 460 is arranged, this plate has the notch 465 that is configured to receivability locking cam 416.Plate 460 can be a part that separates, and uses such as welding or screw in the back door 400 ", perhaps plate 460 can with back door 400 " be configured as one.In addition, locking cam 416 can be shaped as towards the back door 400 " step shape, so that locking cam 416 is removed from the inboard of network cabinet 10.This can reduce the danger that the cable or wire of 10 li of network cabinets was clamped or blocked to locking cam 416.

From Figure 10 E as can be seen, when bolt lock mechanism 405A was shown in an open position, locking cam 416 was stretched downwards and is not engaged in notch 465, back door 400 ', 400 " can be opened.On the contrary, from Figure 10 F as can be seen, when bolt lock mechanism 405A was moved to off-position, locking cam 416 rotated and becomes approximate horizontal and be engaged in notch 465 up to it.When being in this position, back door 400 " closed thereon and be lockable by back door 400 ' overlap joint owing to locking cam 416 is engaged in notch 465.

With reference to Figure 11, in the back door 400 each can be conducted electricity by the hinge component 435 of a spring-loaded and is connected in top cover 200, and therefore conduction is connected in main frame 100, 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 that this provides conduction to connect between body 440 and 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, pass body 440 the end the hole and be screwed into joint pin 445 with screw thread.Spring 450 is made by electric conducting material usually, and is positioned in the body 440 and is compressed between joint pin 445 and the body 440.Spring 450 joint pin 445 from body 440 to extrapolation, when release arm 455 is drawn, allow joint pin 445 to return, and as a kind of conduction ways of connecting that provides between joint pin 445 and the body 440.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 contact conductions are connected in the screw 255 of top cover 200.

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 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 the screw 255 connects.

In order to install or pull down back door 400, can pull down release arm 455, its compression spring 450 also makes joint pin 445 return to 440 li of bodies.Be in the height of lining 260 when following at joint pin 445, just can install back door 400 on the throne or remove.In case it is on the throne that install at back door 400, release arm 455 just is released, and spring 450 passes lining 260 to extrapolation joint pin 445, up to joint pin 445 contact screws 255.

In this example, when installing back door 400, the hinge component 435 of spring-loaded provides linkage and reliable grounding path also is provided for back door 400.This allows to pull down back door 400 and need not to untie any ground connection cross-over connection lead.

With reference to Fig. 2 A and 2B, in this example, door mount pad 15 is also porose 18, and it inwardly is provided with from lining 600, and lining 600 receivabilities are used for the joint pin that the bottom at back door 300 is fixed.Though it is mutual minute surface symmetries that Fig. 2 A and 2B express door mount pad 15, two the door mount pads 15 that are used for Qianmen 500, and a mount pad 15 that is used for back door 400 has identical hole 18.With reference to Fig. 4 A, 4B and 11, top cover 200 is porose 265, and it inwardly is provided with 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 provides one to put laying mechanism in the hole 265 of aiming at the correspondence on the top cover 200 on the axis of approximate vertical and for the back door 400 that has been removed.

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 can remove back door 400.Needn't lean against the back door 400 that removes on the rack 10 or lean against on the wall or lean against on the miscellaneous equipment that may be clashed into or knock over, but can place the back door 400 that removes with each hole 18 and 265 on door mount pad 15 and the top cover 200.The back door 400 that removes for placement, can open relative back door, 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 that removes, and, the joint pin 445 of the linkage 435 of spring-loaded is injected the hole 265 of the correspondence on the top cover 200 by pulling down release arm 455.

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 roughly rectangular steel plates, its can be atresia or get out some holes for attractive in appearance and circulation of air, the scalable hinge of this usefulness two is hinged at bilateral, this will describe in detail hereinafter, this door can by from the left side or the right open, can be thereby open wide, and needn't pull down Qianmen 500 near the path of a left side or right bar frame and vertical cable management conduit.Perhaps, 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, uses any made, makes any structure form.

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

With reference to Figure 12 A, 500 each top corners and bottom corner at the Qianmen (having four positions) have a locking hinge assembly 535.Figure 12 B and 12D express the locking hinge assembly 535 on two bottom corner at Qianmen 500, will be understood that two hinge component and hinge components on the bottom corner described herein on the top corners are identical.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 and stop assembly, and this hinge component comprises hinge lever 540, hinge bracket 542 and joint pin 545, lever stopper 555 and outer lever retainer 570 in this stop assembly comprises.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 the wall 543 of approximate vertical, and it is by being fixed in Qianmen 500 such as welding, screw or the like, 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, makes hinge lever 540 to rotate around bearing pin 560.Hinge lever 540 also is connected in lower beam 525 (or upper boom 520, this according to be which locking hinge assembly) rotationally and is connected in joint pin 545 with its other end with the 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 joint pin 550 is fixed in Qianmen 500, and lever stopper 555,570 is installed on the lever stop joint pin 550, makes lever stopper 555,570 to rotate around joint pin 550.Each lever stopper 555,570 has the stopper arms 556,571 of approximate vertical and the release arm 557,572 of approximate horizontal respectively.A torque spring 565 or other elastic component are installed on the lever stop joint 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 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 the top cover 200 and two bottom corner at Qianmen 500 lean against on the 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 each lining 600 corresponding on a mount pad 15 or the top cover 200 with them.So the joint pin 545 on each in four bights at Qianmen 500 all is engaged in the lining 600 of the correspondence on a mount pad 15 or the top cover 200, Qianmen 500 will be pinned fully like this.In addition, when 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 move away the rotation path of hinge lever 540.This will allow hinge lever 540 freely to rotate to either direction.Especially with reference to Figure 12 B, when door handle when off-position forwards open position to, lower beam 525 is pushed down, hinge lever 540 rotates around bearing pin 560, and joint pin 545 is contracted.These joint pin 545 hinge commentaries on classics that Qianmen 500 is stretched out around the maintenance of opposition side are opened.On the contrary, when lower beam 525 is lifted (for example door handle is pulled off-position from open position), hinge lever 540 will stretch out joint pin 545 around bearing pin 560 rotations.

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

With reference to Figure 12 B, 500 by when off-position moves at the Qianmen, and 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 is shifted onto anteposition.Because hinge lever 540 still is being lockable the position, interior lever stopper 555 is hindered by hinge lever 540 and can not rotate forward.But 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, thereby stop 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, thereby stop door handle to be pulled.If the hinge of opposite side has been broken away from and Qianmen 500 has been opened, this can prevent that the hinge that meshes is unexpectedly broken away from.If can not prevent this unexpected disengaging, 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, break away from for Qianmen 500 is removed, must be made the locking hinge assembly 535 that is opened in this side from off-position.When 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.Broken away from and after Qianmen 500 moved apart off-position, door mount pad 15 no longer pushed the release arm 557,572 of lever stopper 555,570, and torque spring 565 tries hard to lever stopper 555,570 is shifted onto anteposition at locking hinge assembly 535.Because hinge lever 540 has been moved apart locked position, outer lever retainer 570 is subjected to stopping of hinge lever 540 and can not rotates forward.But 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, thereby stop 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, thereby stop door handle to be pulled.This will stop door handle to be closed, and 500 are in complete off-position up to the Qianmen, make lever stopper 555 be pushed rearward, thereby not hinder hinge lever 540 to allow joint pins 545 to be pushed downwards and mesh lining 600 fully.

From as can be seen above-mentioned, 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 break away from) at Qianmen 500 the user.This can reach such two free-revving engines: (1) can prevent the unexpected of Qianmen 500 or come off (in a side is when opening, and opposite side is lockable and can not be broken away from, and 500 are closed up to the Qianmen) unexpectedly; And (2) can prevent that the user is still at Qianmen 500 and think that it is to have closed (be fully closed at Qianmen 500 and before lever stopper allowed the hinge lever motion, door handle can not be moved to off-position) when half-open mistakenly.

In order to pull down Qianmen 500, at first Qianmen 500 is placed on 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.When being in this off-position, pull two door handles, these two door handles will break away from all locking hinge assemblies 535 by making upper boom and lower beam 520,525 and making each joint pin 545 stretch out and return from separately lining 260,600 respectively, and this just allows to pull down Qianmen 500.In case Qianmen 500 has been removed, lever stopper 555 is just shifted onto their anteposition in each 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 said process conversely.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 be in pusher lever stopper 555 and make it not hinder hinge lever 540, 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 is expressed in the engagement on the side at Qianmen 500, between the joint pin 545 at Qianmen 500 and the door mount pad 15, and should be appreciated that, also is same in the engagement on the opposite side at Qianmen 500, between joint pin 545 and the door mount pad 15.Joint pin 545 stretches out and is engaged in lining 600 in the hole on the end face that is positioned at a mount pad 15.In this example, promoting screw 605 aims at joint pin 545, be screwed into the just bottom of the door mount pad 15 under the lining 600 that is engaged in joint pin 545 with screw thread, and bearing-surface 607 is provided, the bottom of this bearing-surface contact joint pin 545 also provides joint pin 545 supporting surfaces thereon.Along with door handle is pulled off-position, joint pin 545 moves downward the bearing-surface 607 that passes lining 600 and contact lifting screw 605.Joint pin 545 continues to move downward, and leaves lining 600 when joint pin 545 promotes Qianmen 500 during at complete extended position.So Qianmen 500 is raised and is being supported by joint pin 545 rather than lining 600, this can provide the gap between the threshold 19 of Qianmen 500 and door mount pad 15 and the sinking and/or the accumulation of the tolerance under the worst case of compensation door when closing Qianmen 500.In addition, can adjust the rise that promotes screw 605, thereby adjust the rise of Qianmen 500 above the threshold 19 of door mount pad 15.Perhaps, do not adopt the lifting screw, the lining of aiming at joint pin 545 and have a bearing-surface that contact joint pin 545 can be inserted in the hole of bottom of a mount pad 15, to mention the Qianmen.In addition, do not adopt to promote screw or lining, door mount pad 15 can be designed to provide bearing-surface.For example, the bottom of door mount pad 15 can form such height, and the upper surface of bottom provides the bearing-surface and the Qianmen 500 that raises of contact joint pin 545.

In above-mentioned example, when the weight at Qianmen 500 is being supported by joint pin 545 (rather than being bearing on the lining 600), there is a constant masterpiece to be used on the joint pin 545 and tries hard to joint pin 545 is shifted onto retracted position.If the engagement fully of 500 door handles 510 when in the closed position at the Qianmen, this power on the joint pin 545 of acting on may make door handle 510 rotate and locking hinge assembly 535 is thrown 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: the door handle (not shown); Be connected in the lobe plate 515A of door handle, rotation axis is rotated thereby door handle and lobe plate 515A rotate together; And the upper boom and the lower beam 520,525 that are connected in the protruding wide part of lobe plate 515A rotationally, rotation axis is rotated thereby they rotate separately.The main distinction between bolt lock mechanism 505 and the 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 and door handle.On the contrary, two the protruding wide parts the 517, the 518th of the lobe plate 515A in the overhead cam bolt lock mechanism 505A, roughly mutually perpendicular and protruding from the pivot center of lobe plate 515A and door handle.

Can be clear that from Figure 12 G, at the Qianmen 500 and door handle is in the closed position and each locking hinge assembly 535 be the engagement the time, protruding wide part 517 perpendicular that are connected in lower beam 525 (and then underneath hinges pin 545) are extended, and are connected in the protruding wide part 518 substantial horizontal extension of upper boom 520 (and then top joint pin 545).At work, act on the power (such as the weight at the Qianmen 500 of supporting) that trying hard on the joint pin 545 return joint pin 545 and will make downward acting on the lower beam 525 by joint pin 545.But because protruding wide part 517 is to be in vertically, this downward power that acts on the lower beam 525 can not make lobe plate 515A (and then door handle) rotate.In order to turn the handle and lobe plate 515A, must apply an effective rotatory force to door handle, make door handle move to open position, and make protruding wide part 517 move to horizontal level and protruding wide part 518 moves to the upright position from horizontal level from the upright 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 the joint pin 545 is rotated.

With reference to Figure 13, in this embodiment, the bearing assembly 610 of Qianmen 500 by spring-loaded also conducts electricity and is connected in top cover 200.The bearing assembly 610 of two spring-loaded is positioned to be installed in respectively two opposite 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 the open position process at Qianmen 500, the bearing assembly 610 of spring-loaded keeps contacting with Qianmen 500.By the bearing assembly 610 that adopts two spring-loaded, Qianmen 500 all keeps conduction to be connected in top cover 200 left to the right when closing, opening or opening.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 the external screw thread of the corresponding internal thread of the not paint covering that can be screwed on the top cover 200 is arranged, and be screwed into the surface of panel 625 contact top covers 200, this bearing assembly 610 and the conduction between the top cover 200 that can set up spring-loaded connects always.Ball bearing 620 be steel or other electric conducting material, thereby its spring 630 by electric conducting material is pressed to panel 625 and projection and is exceeded outside the panel 625 end face up to contact Qianmen 500.On the end face at Qianmen 500, the place of ball bearing 620 contacts does not have skin of paint, and this bearing assembly 610 and the conduction between the Qianmen 500 that can set up spring-loaded connects.Bearing assembly is positioned to close enough lining 600 and joint pin 545, makes Qianmen 500 can be opened to about 160 degree and still can keep the conduction between Qianmen 500 and the top cover 200 to connect.The conduction connection of setting up between Qianmen 500 and the top cover 200 with the bearing assembly 610 of spring-loaded allows to pull down Qianmen 500, and needn't disconnect any cross-over connection lead.

Perhaps, can find out from Figure 12 B and 12E, connect without the conduction of Qianmen 500 by 610 pairs of main frames 100 of bearing assembly of the spring-loaded on the top cover 200, and can allow Qianmen 500 be connected in main frame 100 by lifting screw 605 conductions on locking hinge assembly 535 and the door mount pad 15, as mentioned above, this lifting screw conduction is connected in main frame 100.Connect Qianmen 500 in order to conduct electricity by this way, elder generation conducts electricity lifting screw 605 and is connected in a mount pad 15.Its practice is, promote screw with a trigonodont, an internal tooth lock washer is placed between the head and door mount pad that promotes screw, or the lifting screw of tooth is arranged, perhaps allow head of that part contact lifting screw of not paint of a mount pad with a head of screw lower surface.Then, by such as the cross-over connection lead fixed between joint pin 545 and Qianmen 500, joint pin 545 conduction is connected in Qianmen 500.So when joint pin 545 contacts promoted screw 605, just the conduction of having set up between Qianmen 500 and the door mount pad 15 by cross-over connection lead, joint pin 545 and lifting screw 605 connected.Perhaps, if replace to promote screw 605 with lining, as mentioned above, thereby then lining can conduct electricity and is connected in a mount pad 15 and provides the conduction between joint pin 545 and the door mount pad 15 to connect.For example, can between the head of lining and door mount pad 15 internal tooth lock washer be set, lining can have tooth at the head downside, perhaps can allow the zone paint not of a mount pad 15 contact bushes.

From above detailed description as can be seen, in this embodiment, when network cabinet 10 assembled up fully, all parts of this rack all conducted electricity and have coupled together.Each member that constitutes main frame 100 all conducts electricity by welding together and has connected.Door mount pad 15, equipment guide rail 20 and top cover 200 are connected in main frame 100 by adopting conductions such as internal tooth lock washer, trigonodont screw.Side plate 300 is connected in top cover 200 by adopting earth clip 335 conductions.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 or by locking hinge assembly 535.Couple together by all parts of this rack are all conducted electricity, just do not need each independent ground connection cross-over connection lead, 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.
