Embodiment

Below in conjunction with accompanying drawing of the present utility model, most preferred embodiment of the present utility model is described in more detail.

Be illustrated in figure 1 as switch cubicle door schematic diagram of the present utility model, this switch cubicle door comprises panel 1, centers on the flanging 2 of panel, this switch cubicle door has hook 3 at back side of panel, it cooperates with a plurality of holes 9 on the switch cubicle doorframe, it is fixed to be used for cabinet door lock, a

hole

4,5 is also respectively arranged on the last lower hem, these two holes are located on the left side or the right side of lower hem, and it is coaxial in vertical direction, it cooperates with upper hinge 6 and play hinge 7 on the switch cubicle doorframe, and can make the cabinet door is the center rotation with the vertical axis.

Fig. 2 A, Fig. 2 B are respectively switch cubicle header of the present utility model and elevated bottom perspective view; Switch cubicle door of the present utility model also comprises bottom bending edge 8, the position above being in when the simple installation of lower position hinge can make door open wide.On the lower surface of door an opening is arranged, makes, can move on to lower position when door during in off-position, bottom making bending edge 8 be stuck in the switch cubicle doorframe in, be used for switch cubicle closed tightly.In conjunction with cooperating of the hole on the hook at the switch cubicle door back side and the switch cubicle doorframe, after switch cubicle door of the present utility model is closed, three limits (limit, the left and right sides and bottom) and switch cubicle doorframe tight closure are arranged.Therefore switch cubicle door of the present utility model does not need the lock that adds, can make firmly closure closely of switch cubicle door and switch cubicle.

Fig. 3 is the enlarged drawing of the hinge that cooperates with switch cubicle door of the present utility model, and wherein Fig. 3 A is the hinge that the hole on the top flap of switch cubicle door cooperates, and Fig. 3 B is the hinge that the hole on the bottom flap of switch cubicle door cooperates; Upper hinge 6 length on the switch cubicle doorframe are bigger than following hinge 7 length, the length difference of hinge is greater than the thickness of switch cubicle door flanging 2 up and down, like this can so that the switch cubicle door be raised the time, can disassemble, and normal the use time, can not fall down from the cabinet doorframe again.Fig. 4 is that the length of hinge up and down compares, and also as can be seen, upper hinge length is bigger than following hinge length from figure.

Further, go back jug 10 on the switch cubicle door of the present utility model, make things convenient for the opening and closing of cabinet door, below the cabinet door handle, have two or more observation windows 12, be used under the situation of not opening door of switch cabinet, can observing the situation of switch cubicle inside.

Further, switch cubicle door upper hem of the present utility model edge is interlocking locking plate 11 also, and it cooperates with interlock, prevents that the switch cubicle door from illegally being opened.Those skilled in the art knows, when switch cubicle does not have ground connection, the switch cubicle door is breakneck by incorrect opening, at this moment, when the switch cubicle door is upwards mentioned, interlocking locking plate 11 is stoped by the bayonet lock of interlock, and then interlocking locking plate 11 hinders the switch cubicle doors and upwards be raised, thereby has prevented that the switch cubicle door is opened.When switch cubicle ground connection, carry on the bayonet lock of interlocking locking plate, cancelled the prevention that switch cabinet door upwards is raised.

Fig. 6 is the cupboard doorframe three-dimensional view that cooperates with door of switch cabinet; Fig. 7 is switch cubicle door and the doorframe three-dimensional view that has the utility model cabinet door.As shown in the figure, the hook of switch cubicle door is through respectively in the hole of switch cubicle doorframe, when being in off-position, these hooks 3 and hole 9 cooperate, do not need the lock that adds, limit, the switch cubicle door left and right sides and bottom bending edge 8 all with switch cubicle doorframe tight closure, the switch cubicle door is locked fully.

Further, be fixed on the screw of joint pin by removal, door can be made into movably by the user.Pin itself is exactly fixing as rivet, need not welding.The door of band fixing point be by a metallic plate make make it can not have mechanical lifting mechanism the time because too heavy and can't carry.

According to switch cubicle door of the present utility model locking that conventional overhang-door has and withstand voltage performance are arranged, and the easy use of common overhang-door, the advantage of removal are easily arranged.In addition, be making of a metallic plate according to switch cubicle door of the present utility model, the function of lock does not need extra parts; This makes that also door is very light, does not need the device of slinging of additional operations link.But also do not need welding, do not need hold-down screw or use the rivet stickfast.

Although disclose preferred embodiment of the present utility model and accompanying drawing for the purpose of illustration, the person skilled in the art in the spirit and scope that do not break away from the utility model and appended claim, can do various replacements, variation and retouching; For example, shown in the present embodiment, be used to make the hinge of switch cubicle door rotation and the left side that the hole is positioned at the cabinet door, those skilled in the art will find apparent that, also may make door assembly with hinge and glass in right hand and left and the hole of matching be positioned at the right side of switch cubicle door as mirror image.Therefore, the utility model should not be limited to preferred embodiment and the disclosed content of accompanying drawing, and protection range of the present utility model is as the criterion with the scope that appending claims was defined.
