[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0031] like Figure 1 and Figure 2As shown, an embodiment of the utility model provides a cabinet door, which includes a door frame 10, a cabinet door body 20, a connecting rod lock 30 and a sealing assembly 40. The door frame 10 includes a frame body 11 and a partition 12. The frame body 11 includes an opening. The partition 12 is arranged on the frame body 11 in the horizontal direction to divide the opening into a plurality of hatches 111 arranged in the vertical direction. The cabinet door body 20 has a hinged end and a free end arranged oppositely. The hinged end of the cabinet door body 20 is rotatably arranged on the door frame 10, and the cabinet door body 20 can block a plurality of hatches 111. The connecting rod lock 30 is arranged at the free end of the cabinet door body 20, and the connecting rod lock 30 extends in the vertical direction. The connecting rod lock 30 can cooperate with the door frame 10 to fix the cabinet door body 20, and the connecting rod lock 30 is arranged on the partition 12. The sealing assembly 40 is arranged between the connecting rod lock 30 and the partition 12, and the sealing assembly 40 is used to seal the gap between the connecting rod lock 30 and the partition 12.

[0032] By applying the technical solution of the present application, the partition 12 can divide the opening of the frame body 11 into a plurality of hatches 111 arranged in the vertical direction, the connecting rod lock 30 is passed through the partition 12, and the connecting rod lock 30 cooperates with the door frame 10 to fix the cabinet door body 20, and a sealing assembly 40 is arranged between the connecting rod lock 30 and the partition 12 to fill the gap between the connecting rod lock 30 and the partition 12. Such an arrangement can achieve the sealing of two adjacent cabins in the vertical direction, and at the same time can achieve a flame retardant effect, thereby effectively preventing the spread of fire and the like, and avoiding greater safety hazards. At the same time, the use of one cabinet door body 20 to achieve the sealing of multiple cabins can effectively reduce the manufacturing cost, and facilitate the staff to repair the internal components of the electrical cabinet, avoiding opening and closing multiple cabinet door bodies 20.

[0033] The door frame 10 may include only one partition 12 or multiple partitions 12. In the present application, the door frame 10 includes only one partition 12, and the partition 12 divides the opening into two hatches 111 arranged in the vertical direction.

[0034] Among them, the partition 12 is provided with an escape groove 121 on one side facing the cabinet door body 20, the escape groove 121 penetrates the partition 12 in the vertical direction, the sealing assembly 40 is engaged and sealed with the escape groove 121, one side of the sealing assembly 40 is fixedly connected to the cabinet door body 20, and the connecting rod lock 30 is passed through the sealing assembly 40. Such a configuration is convenient for processing the partition 12, and at the same time, it is convenient to arrange the connecting rod lock 30 and the sealing assembly 40, with a simple structure and convenient operation.

[0035] Specifically, the door frame 10 includes a vertical beam 112 and a horizontal beam 113 . The vertical beam 112 is provided with a slot, and the connecting rod lock 30 cooperates with the slot to fix the cabinet door body 20 .

[0036] Among them, a first sealing part is arranged on the cabinet door, and a second sealing part is arranged on the door frame 10. When the cabinet door is closed, the first sealing part and the second sealing part are tightly fitted to complete the sealing between the cabinet door and the door frame.

[0037] In the present application, the connecting rod lock 30 is arranged on the inner side of the vertical beam 112, that is, on the inner side of the second sealing part, so it is necessary to set a slot on the vertical beam 112 and set an avoidance groove 121 on the partition 12. However, in the prior art, the connecting rod lock 30 is arranged on the outer side of the vertical beam 112, that is, on the outer side of the second sealing part, so that the door frame 10 needs a certain width to set the connecting rod lock 30. However, such a setting will increase the width dimension of the vertical beam 112, that is, the dimension of the vertical beam 112 along the extension direction of the cross beam 113. However, in the present application, the width dimension of the vertical beam 112 can be effectively reduced, thereby improving the space utilization of the electrical cabinet, reducing the structural dimensions of the electrical cabinet, and further reducing the manufacturing cost of the electrical cabinet.

[0038] like Figure 3 and Figure 4 As shown, the sealing assembly 40 includes a connecting member 41, a first sealing member 42 and a second sealing member 43. The connecting member 41 is fixedly connected to the cabinet door body 20, and the connecting member 41 has a accommodating cavity 411, a first connecting hole 412 and a second connecting hole 413. The first connecting hole 412 and the second connecting hole 413 are both connected to the accommodating cavity 411, and the connecting rod lock 30 is penetrated on the connecting member 41 through the first connecting hole 412 and the second connecting hole 413. The first sealing member 42 is arranged between the first connecting hole 412 and the connecting rod lock 30. The second sealing member 43 is arranged between the connecting member 41 and the avoidance groove 121. In this way, the first sealing member 42 can achieve the sealing between the first connecting hole 412 and the connecting rod lock 30, and the second sealing member 43 can achieve the sealing between the connecting member 41 and the avoidance groove 121, thereby ensuring the sealing effect of the sealing assembly 40.

[0039] Specifically, the connecting member 41 is a sheet metal member, and a flange structure is provided on one side of the connecting member 41 close to the cabinet door body 20 , and the flange structure is welded and fixed to the cabinet door body 20 .

[0040] In addition, the second sealing member 43 surrounds the outer circumference of the connecting member 41. The second sealing member 43 can be made of expanded graphene sealing strips, which are pasted on the side walls of the connecting member 41. In this way, when a fire occurs in a cabin and the temperature rises, the expanded graphene sealing strips can expand in all directions. The expansion volume is 100-300 ml / g, which can seal and fill the gap between the two cabins to form a fire and smoke barrier.

[0041] Specifically, the first sealing member 42 is made of elastic material.

[0042] Specifically, the first connection hole 412 is a round hole, and the second connection hole 413 is a waist-shaped hole, and the second connection hole 413 can avoid the horizontal displacement of the connecting rod lock 30. Since the connecting rod lock 30 will have a horizontal position during the opening and closing process of the cabinet door, such a setting can ensure the normal movement of the connecting rod lock 30, avoid interference between the connecting rod lock 30 and the connecting member 41, and the structure is simple, which is convenient for processing the connecting member 41.

[0043] Among them, in the present application, the diameter of the first connecting hole 412 is larger than the length dimension of the waist-shaped hole. Because the first sealing member 42 needs to be set in the first connecting hole 412, and the connecting rod lock 30 needs to be horizontally displaced after being inserted into the first sealing member 42, and the horizontal displacement distance of the connecting rod lock 30 in the first sealing member 42 and the second connecting hole 413 is the same, so the diameter of the first connecting hole 412 needs to be larger than the length dimension of the waist-shaped hole, so as to ensure the normal movement of the connecting rod lock 30.

[0044] like Figure 5 As shown, the outer side wall of the first sealing member 42 is provided with an annular groove 421, and the annular groove 421 is engaged with the first connecting hole 412. Such a configuration facilitates fixing the first sealing member 42 on the connecting member 41, while avoiding the need to use parts to fix the first sealing member 42, and the structure is simple, while facilitating the processing of the first sealing member 42 and convenient operation.

[0045] The diameter of the bottom of the first sealing member 42 gradually decreases in the direction away from the annular groove 421, that is, the diameter of the first connecting section 422 gradually decreases in the direction away from the annular groove 421. In this way, when the first sealing member 42 is fixed to the connecting member 41, the first connecting section 422 can play a guiding role, thereby reducing the difficulty of fixing the first sealing member 42 and facilitating assembly by the staff.

[0046] Furthermore, a notch 414 is provided on the side wall of the first connection hole 412, and the notch 414 is in communication with the first connection hole 412. Since the annular groove 421 is engaged with the first connection hole 412, and the first sealing member 42 is made of elastic material, the staff needs to squeeze the first sealing member 42 into the first connection hole 412, and the notch 414 on the first connection hole 412 provides space for installing the first sealing member 42, so that the staff can squeeze the first sealing member 42 into the first connection hole 412, which is simple to operate and reduces the working difficulty of the staff.

[0047] Specifically, the diameter of the top of the first sealing member 42 gradually decreases along the direction away from the annular groove 421, that is, the diameter of the second connecting section 423 gradually decreases along the direction away from the annular groove 421. In this configuration, since the first sealing member 42 is made of elastic material, the staff needs to overcome the squeezing force when inserting the connecting rod lock 30 on the first sealing member 42. Since the diameter of the top of the second connecting section 423 is small, the squeezing force that the staff needs to overcome when inserting the connecting rod lock 30 on the first sealing member 42 is small, which facilitates the insertion of the connecting rod lock 30 on the first sealing member 42, further reducing the assembly difficulty of the staff.

[0048] Furthermore, a third sealing member 50 is provided between the door frame 10 and the cabinet door body 20, that is, the third sealing member 50 is provided between the first sealing portion and the second sealing portion. The third sealing member 50 is a sealing strip, which can ensure the sealing effect between the door frame 10 and the cabinet door body 20, and further avoid the communication between two adjacent compartments in the vertical direction.

[0049] Another embodiment of the utility model provides an electrical cabinet, which includes a cabinet body and the cabinet door provided above, wherein the cabinet body includes multiple compartments, and the multiple compartments are arranged one-to-one with the multiple compartment doors 111 of the cabinet door. Such an arrangement can achieve flame retardant sealing of two adjacent compartments in the vertical direction, and prevent the fire from spreading to the adjacent compartment after one compartment catches fire, which is convenient for the staff to carry out maintenance and avoids further increase of danger.
