In order to accurately distinguish the low-pressure secondary apparatus and the operating mechanism, a partition plate may be used to make different spaces in the upper chamber 21, and the low-pressure secondary apparatus and the operating mechanism may be installed in the different spaces.

The upper chamber 21 of the present utility model includes a housing 211 and a side-by-side door 212. The box 211 includes a back plate (not shown), two side plates 2111 and a top plate 2112, and the side-by-side door 212 includes a first door 2121 and a second door 2122, which are respectively fixed to the two side plates 2111.

The back plate, two side plates 2111 and one top plate 2112 are sequentially connected to form a box 211, and two doors are arranged on the side plates 2111 in a split mode. For example, each door is secured to side plate 2111 by door hinge 213. Fig. 2 shows the case where the side-by-side door 212 is closed. In addition, the housing 211 may also include a floor to isolate the cable chamber 22 below.

The cabinet door of the utility model adopts the form of the split door 212, so that the cabinet door can be opened without being lifted up too high, and the split door 212 is conveniently closed by staff, thereby bringing great convenience. In addition, the side plate 2111 and the back plate of the air box, the operating mechanism and the low-voltage secondary equipment are also the side plate 2111 and the back plate of the outdoor switch cabinet 2, namely, the mechanism of each chamber is directly arranged in the outdoor box, so that materials can be saved, and the cost can be reduced.

Alternatively, the side plate 2111 of the case 211 is integrally formed with the side plate 2111 of the cable chamber 22, and the back plate of the case 211 is integrally formed with the back plate of the cable chamber 22. That is, the side plate 2111 of the upper chamber 21 and the side plate 2111 of the cable chamber 22 may be the same side plate 2111, and the back plate of the upper chamber 21 and the back plate of the cable chamber 22 may be the same back plate. Thus, the side panels 2111 and the back panel of the cable chamber 22 are also the side panels 2111 and the back panel of the original outdoor box, which saves materials and reduces costs.

Optionally, the outdoor switch cabinet 2 of the present utility model further comprises a door lock handle 23, the door lock handle 23 being located on one of the two doors. As can be seen in fig. 2, the door lock handle 23 is located on the second door 2122. The door lock handle 23 can open the side-by-side door 212, which is convenient and quick. Of course, the outdoor switch cabinet 2 may further include another door lock handle 23, where the two door lock handles 23 are respectively disposed on a door, and may be specifically set according to actual needs.

As an example, the side of the first door 2121 facing away from the case 211 has a fold 21211, and the fold 21211 is located inside the second door 2122 when the side-by-side door 212 is closed. As shown in fig. 3, after the side-by-side doors are closed, the fold 21211 can be located inside the second door 2122, and the first door 2121 can be opened only when the second door 2122 is opened. The fold 21211 may be a flat plate that is integrally formed with the first door 2121. By adopting the folded edge 21211, the two doors can be closed only by arranging one door lock handle 23 on the second door 2122, and the structure is simple and the cost is low.

Optionally, the outdoor switchgear 2 of the present utility model further comprises a door locking device 24. The door locking device 24 is secured to the side-by-side door 212. The door locking device 24 is interlocked with the door lock handle 23, and the operating room comprises at least one insert 31, which insert 31 can be positioned on the top plate 2112, the door locking device 24 being movable between a closed position extending into the insert 31 and an open position moving out of the insert 31 in case of a rotation of the door lock handle 23. The door locking device 24 can be linked with the door lock handle 23, and the door lock handle 23 can rotate to drive the door locking device 24 to lock the side-by-side door 212 in the closed position, and the side-by-side door 212 can be opened when the door locking device 24 is positioned in the open position. The door locking device 24 extends into the embedded part 31, the side-by-side door 212 cannot be opened, and the door locking device 24 moves out of the embedded part 31, so that the side-by-side door 212 can be freely opened. The door lock device 24 and the door lock handle 23 are interlocked, whereby the side-by-side combination door 212 can be locked. It is conceivable that a key hole may be provided on the door lock handle 23, and the key may be inserted into the key hole to rotate the door lock handle 23, so that only a person having authority of the key can rotate the door lock handle 23, thereby ensuring personal safety of the person. In this embodiment, the embedded portion 31 is, for example, a hole.

The door locking device 24 may be disposed inside the side-by-side door 212 such that someone is prevented from damaging the door locking device 24. As an exemplary illustration, the number of door locking devices 24 may be 2, and each door locking device may correspond to one door lock handle 23, and may be disposed on the inner side of the first door 2121 and the inner side of the second door 2122, respectively.

As an exemplary illustration, as shown in fig. 3 and 4, the door locking device 24 includes at least one latch assembly, each latch assembly including a link 241 and a moving member 242. Wherein one end of the link 241 is hinged to the door lock handle 23, one end of the moving member 242 is hinged to the other end of the link 241, and the other end of the moving member 242 can be extended into the embedded portion 31 or removed from the embedded portion 31. The structure is simple, the implementation is convenient, and the cost is low. As an exemplary illustration, as shown in fig. 3, when the door lock handle 23 is turned, the link 241 is driven to move in the direction D, so that the moving member 242 is separated from the embedded portion 31 and is in the open position. By rotating the door lock handle 23 in the opposite direction, the link 241 is driven to move in the opposite direction to the direction D, so that the moving member 242 extends into the embedded portion 31, and the side-by-side door 212 cannot be opened in the closed position.

Optionally, the locking assembly further includes a limiting member fixed to the side-by-side door 212, and the moving member 242 is provided with a long hole 2421, and the limiting member is located in the long hole 2421. As can be seen from fig. 3, the moving member 242 can only move up and down along the extending direction D of the elongated hole 2421 due to the stopper during the movement. The limiting member can limit the moving direction of the moving member 242, and thus can ensure that the moving member 242 accurately extends into the embedded portion 31 or moves out of the embedded portion 31. The stop member may in particular be a pin or bolt.

Alternatively, the moving member 242 of the present utility model has an arc shape toward one end of the embedded portion 31. The arc shape enables the mover 242 to slide into the embedded part 31 relatively easily. As a specific example, the moving member 242 has two protruding ends 2423 at one end for extending into the embedded portion 31, the two protruding ends 2423 are parallel to the moving direction D, and there may be two embedded portions 31, each protruding portion extending into one of the embedded portions 31.

Alternatively, as shown in fig. 4, the mover 242 has at least one

hook

2422, 2 hooks 2422 being shown in fig. 4. As shown in fig. 3, the case 211 has a protrusion 2113 corresponding to the hook 2422, the protrusion having a through hole 21131, and the hook 2422 is capable of switching between a position moved into the through hole 21131 and a position moved out of the through hole 21131 when the mover 242 moves. For example, with door lock device 24 in the closed position, hook 2422 is located in throughbore 21131, and with door lock device 24 in the open position, hook 2422 is located outside throughbore 21131. By the engagement of the hooks 2422 with the protrusions 2113, the closing of the side-by-side doors 212 can be made more secure. The protrusion 2113 may be provided on a bracket of the housing 211, and the flange 21211 has a corresponding hole so that the protrusion 2113 can protrude.

Alternatively, the number of locking assemblies is 2, and the embedded parts 31 may be respectively located on the top and one bottom plate of the upper chamber 21, and each embedded part 31 corresponds to one locking assembly, that is, the locking assemblies are symmetrically distributed about the rotation axis of the door lock handle 23. As shown in fig. 3 and 4, the case 211 may also have a protrusion 2114, and the protrusion 2114 may have an embedded portion 31, because the top of the case 211 is not the same as the bottom plate, and thus a separate protrusion 2114 may be provided. As shown in fig. 3, the protruding portion 2114 is located near the floor of the floor box 211. The protruding portion 2114 may be provided on a bracket of the case 211, and the flange 21211 has a corresponding hole so that the protruding portion 2114 can protrude. Thus, the door lock handle 23 can rotate and simultaneously drive the two moving members 242 to extend into the embedded part 31 or move out of the embedded part 31. The use of two latch assemblies can provide a stronger lock to the side-by-side door 212. Door handle 24 is positioned on second door 2122 and first door 2121 has a fold 21211 thereon, and when second door 2122 is locked, first door 2121 is also prevented from opening due to the obstruction of fold 21211. Thus, the door lock of the outdoor switch cabinet 2 can be locked by the door lock handle 23 and the door locking device 24, and the door lock is simple in result, low in cost and convenient to realize.

The foregoing description of the preferred embodiments of the utility model is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the utility model.
