Fig. 1 shows a cabinet door assembly 1 according to the utility model from the front, comprising a first cable compartment door 100 and a second cable compartment door 200, wherein a cable is plugged into a voltage transformer cabinet through a cable hole 201 provided in the second cable compartment door 200. Fig. 2 shows the first cable compartment door 100 of the cabinet door assembly 1 alone, it being seen that the top of the first cable compartment door 100 has a mounting opening 101, and that the second cable compartment door 200 can be mounted to the first cable compartment door 100 in a mounting direction F from top to bottom as indicated by the arrow in the figure. Preferably, as shown in the rear view of the second cable compartment door 200 in fig. 3B, each cable aperture 201 is provided with a respective sub-cable compartment door 202, each covering a respective cable aperture. The sub-cable chamber door 202 is a passive door capable of sliding up and down, and after the cable is plugged in place, the sub-cable chamber door 202 slides up under the pushing of the cable in the process of mounting the second cable chamber door 200 to the first cable chamber door 100; during the process of removing the second cable door 200 from the first cable door 100, the sub-cable doors 202 slide back down to a position covering the cable holes 201 as the second cable door 200 moves upward away from the first cable door 100.

After the second cable compartment door 200 is in place in the mounting opening 101 of the first cable compartment door 100, it is necessary to lock the second cable compartment door 200 to the first cable compartment door 100, and therefore the cabinet door assembly 1 according to the utility model is also provided with a locking mechanism for effecting the locking between the two cable compartment doors. The latching mechanism includes a latch bolt assembly, a blocking member 320, a baffle 330 and a guide pin 340, wherein the latch bolt assembly and blocking member 320 are disposed on the first cable chamber door 100 and the baffle 330 and guide pin 340 are disposed on the second cable chamber door 200. When second cable compartment door 200 is not installed, blocking member 320 is in a blocking position, preventing rotation of the latch bolt assembly relative to first cable compartment door 100; after the second cable compartment door 200 is mounted to the first cable compartment door 100, the guide pin 340 drives the blocking member 320 to a release position that does not limit the rotation of the latch bolt assembly so that the latch bolt assembly can rotate to a position where the blocking shutter 330 moves up and down, and thus the second cable compartment door 200 cannot move up and down with respect to the first cable compartment door 100, thereby locking the second cable compartment door 200 to the first cable compartment door 100.

Specifically, as shown in fig. 4, the guide pin 340 extends vertically downward from the top side of the second cable chamber door 200 such that when the second cable chamber door 200 is mounted to the first cable chamber door 100 in the mounting direction F from top to bottom, the guide pin 340 also moves downward to actuate the blocking member 320 toward the release position. Referring to fig. 5 and 6, it can be seen that the baffle 330 extends perpendicular to the second cabling chamber door 200 from the inside of the second cabling chamber door 200. As shown in fig. 5 and 6, the latch assembly includes a base 310 and first and second latch arms 311 and 312 extending from the base 310, the base 310 is generally annular, fits over the outer circumference of the lock cylinder 350 and is rotatable with rotation of the lock cylinder 350, and the first and second latch arms 311 and 312 are rotatable with the base 310. The blocking member 320 is pivotally mounted to the mount 102 of the first cabling compartment door 100 with its pivot axis extending in a horizontal direction such that the blocking member 320 can pivot relative to the first cabling compartment door 100. As shown in fig. 7, the blocking member 320 includes a force receiving portion including a force receiving surface 323 configured to contact the guide pin 340 on the second cable chamber door 200, and a blocking portion including a first blocking wall 321 and a second blocking wall 322 spaced apart from the first blocking wall 321 in a horizontal direction, connected by a connection portion 324, and the first blocking wall 321 and the second blocking wall 322 are preferably perpendicular to the connection portion 324.

In fig. 5, blocking member 320 is in a blocking position blocking rotation of the latch bolt assembly such that the latch bolt assembly is in an unlocked position that cannot cooperate with bezel 330 to lock two cable chamber doors. Specifically, in this state, the guide pin 340 on the second cable chamber door 200 has just contacted the force receiving surface 323 of the blocking member 320, and a force for driving the blocking member 320 to pivot has not been applied thereto, so that the force receiving surface 323 is still in a horizontal state, and the first blocking wall 321 and the second blocking wall 322 of the blocking portion are located at both sides of the second latch arm 312, respectively, to block the rotation of the second latch arm 312, so that the first latch arm 311 cannot rotate to a position to be engaged with the shutter 330. In fact, at this point the second cable compartment door 200 is not yet in place in the mounting opening 101 of the first cable compartment door 100, and as can be seen in fig. 5, the flap 330 is located vertically above the first latch arm 311, so at this point the first latch arm 311 should not be allowed to move towards a position overlapping the flap 330 in the vertical direction, otherwise the second cable compartment door 200 would be hindered from being mounted in place on the first cable compartment door 100.

In fig. 6, the guide pin 340 on the second cable chamber door 200 is moved further downward than in the position of fig. 5, and the force-receiving surface 323 of the blocking member 320 is subjected to downward pressure from the guide pin 340, and thus pivoted to a release position away from the latch bolt assembly. At this time, the first blocking wall 321 and the second blocking wall 322 are no longer located on both sides of the second latch arm 312, and thus the latch assembly can be rotated from the unlocked position shown in fig. 5 to the locked position shown in fig. 6, i.e., the position where the first latch arm 311 is located above the shutter 330 on the second cable chamber door 200. It should be noted that in the state shown in fig. 6, the second cable compartment door 200 is already in place in the mounting opening 101 of the first cable compartment door 100, so that the flap 330 is located vertically below the first latch arm 311, at which time the first latch arm 311 is allowed to move toward a position overlapping the flap 330 in the vertical direction, thereby locking the second cable compartment door 200 to the first cable compartment door 100.

It is contemplated that after second cable chamber door 200 is unlocked from first cable chamber door 100 and second cable chamber door 200 is removed from first cable chamber door 100, guide pin 340 on second cable chamber door 200 is no longer in contact with blocking member 320, and thus blocking member 320 can be rotated back to the blocking position from the release position away from the latch bolt assembly. To reset the blocking member 320, the blocking mechanism of the cabinet door assembly according to the utility model is further provided with a resilient member configured to bias the blocking member 320 towards the blocking position. One example of the elastic member is a spring 326 as shown in fig. 8, one end of which is connected to the upper side of the first cable chamber door 100 and the other end of which is connected to the blocking member 320, the spring 326 pulling the blocking member 320 toward the blocking position when the blocking member 320 is not subjected to downward pressure from the guide pin 340. Alternatively, the resilient member may also be a torsion spring (not shown) disposed between the blocking member 320 and the mount 102 of the first cable chamber door 100, which may bias the blocking member 320 toward the blocking position when the blocking member 320 is not subjected to downward pressure from the guide pin 340.

Preferably, the locking mechanism of the cabinet door assembly 1 according to the present utility model is further provided with a key 351, as shown in fig. 2 and 8, which key 351 can be inserted into the locking mechanism for actuating the rotation of the lock cylinder 350, and the rotation of the lock cylinder 350 rotates the latch bolt assembly fitted around the outer circumference of the lock cylinder 350 to lock or unlock the locking mechanism. The key 351 cannot be pulled out of the lock cylinder 350 when the second cable chamber door 200 is not locked with the first cable chamber door 100, and the key 351 can be pulled out when the locking mechanism is locked. In particular, the key 351 can also be used as a key for a grounding operation hole, when the second cable chamber door 200 is locked with the first cable chamber door 100, the key 351 can be pulled out from the cable chamber door for unlocking the grounding operation, and the electric cabinet can start power transmission. Thus realizing the five-prevention function of the electrical equipment.

Although the utility model has been described in the specification and illustrated in the accompanying drawings on the basis of various embodiments, it will be understood by those skilled in the art that the above embodiments are merely preferred implementations, and that certain technical features in the embodiments may not be necessary to solve a particular technical problem so that these technical features may be omitted or omitted without affecting the solution of the technical problem or the formation of the technical solution; furthermore, the features, elements, and/or functions of one embodiment may be combined, or otherwise matched as appropriate with the features, elements, and/or functions of other one or more embodiments, unless such combination, or match is clearly impractical.
