[0049] Referring to FIG. 1, Figures 1 to 4 The locking device of the double-door electrical cabinet provided by the present application, the double-door electrical cabinet has a first door body 10 and a second door body 20, the locking device of the double-door electrical cabinet includes a first frame 100, a second frame 200, a crosspiece 300 and a locking assembly 400, the first frame 100 and the second frame 200 are respectively arranged on the first door body 10 and the second door body 20, the first frame 100 and the second frame 200 are symmetrically arranged and jointly enclose a clamping groove 500, and the crosspiece 300 is detachably inserted into the clamping groove 500.

[0050] The locking assembly 400 includes an acting member 410 and a locking member 420, the acting member 410 and the locking member 420 are both rotationally connected with the second door body 20, the locking member 420 is used for abutting against or disengaging from the first door body 10, the second frame 200 is provided with an avoiding hole 210 which is in communication with the clamping groove 500, and part of the acting member 410 extends into the clamping groove 500 through the avoiding hole 210.

[0051] The acting member 410 is configured to rotate relative to the second door body 20 to abut against the locking member 420 when the locking member 420 abuts against the first door body 10 and the crosspiece 300 is inserted into the clamping groove 500, or disengage from the locking member 420 when the crosspiece 300 disengages from the clamping groove 500.

[0052] It should be noted that the double-door electrical cabinet of the embodiments of the present application can be used in low-voltage and high-voltage power distribution systems, for accommodating electrical components such as circuit breakers, contactors, relays, etc.; can be used for installing communication equipment such as switches, routers, fiber distribution frames, etc.; can also be used for installing controllers and power supply equipment of various industrial equipment, such as machine tool control cabinets, production line control cabinets, etc., and can also be used for installing other equipment, and the embodiments of the present application do not make too many limitations on this.

[0053] Specifically, the locking piece 420 is rotationally connected with the second door body 20, when the locking piece 420 abuts against the first door body 10, the first door body 10 and the second door body 20 are in a closed state. The acting piece 410 is rotationally connected with the second door body 20, part of the acting piece 410 extends into the clamping groove 500 through the avoiding hole 210, when the crosspiece 300 is inserted into the clamping groove 500, the crosspiece 300 exerts a force on the acting piece 410, so as to make the acting piece 410 rotate in the +X direction shown by the arrow in FIG. 12 until the acting piece 410 is separated from the clamping groove 500, at this time, the acting piece 410 abuts against the locking piece 420 to prevent the locking piece 420 from rotating, so that the first door body 10 and the second door body 20 are locked and cannot be opened. Figure 2 Figure 4 When the crosspiece 300 is pulled out of the clamping groove 500, the acting piece 410 loses the external force, and rotates in the -X direction shown by the arrow in FIG. 13 to return to the initial state and extend into the clamping groove 500 again, at this time, the acting piece 410 is separated from the abutment of the locking piece 420, so that the locking piece 420 can be rotated to make the first door body 10 and the second door body 20 be opened.

[0054] When the crosspiece 300 is pulled out of the clamping groove 500, the acting piece 410 loses the external force, and rotates in the -X direction shown by the arrow in FIG. 13 to return to the initial state and extend into the clamping groove 500 again, at this time, the acting piece 410 is separated from the abutment of the locking piece 420, so that the locking piece 420 can be rotated to make the first door body 10 and the second door body 20 be opened. Figure 2 Figure 4 It can be understood that when the normal equipment is in operation, the crosspiece 300 is inserted into the clamping groove 500; when the operating personnel find the faulty equipment, the crosspiece 300 on the electrical cabinet where the faulty equipment is located is pulled out, so as to distinguish the electrical cabinet of the faulty equipment from the electrical cabinet of the normal equipment. Therefore, by setting the crosspiece 300, on the one hand, it can play a distinguishing and reminding role, and solve the problem that the maintenance personnel cannot easily find the faulty equipment; on the other hand, it can lock the first door body 10 and the second door body 20 to prevent the maintenance personnel from mistakenly entering the electrical cabinet of the normal equipment in operation, avoid safety hazards, and improve the safety.

[0055] It can be understood that when the normal equipment is in operation, the crosspiece 300 is inserted into the clamping groove 500; when the operating personnel find the faulty equipment, the crosspiece 300 on the electrical cabinet where the faulty equipment is located is pulled out, so as to distinguish the electrical cabinet of the faulty equipment from the electrical cabinet of the normal equipment. Therefore, by setting the crosspiece 300, on the one hand, it can play a distinguishing and reminding role, and solve the problem that the maintenance personnel cannot easily find the faulty equipment; on the other hand, it can lock the first door body 10 and the second door body 20 to prevent the maintenance personnel from mistakenly entering the electrical cabinet of the normal equipment in operation, avoid safety hazards, and improve the safety.

[0056] ​​In the specific implementation, the horizontal bar 300 can be printed with warning words such as "normal equipment" or "live equipment", and the card slot 500 can be printed with prompt words such as "faulty equipment" or "overhauled equipment". When the horizontal bar 300 is inserted into the card slot 500, the prompt words in the card slot 500 are blocked by the horizontal bar 300, and the maintenance personnel can only see the warning words "normal equipment" or "live equipment" on the horizontal bar 300. When the horizontal bar 300 in the card slot 500 is pulled out, the maintenance personnel can see the prompt words "faulty equipment" or "overhauled equipment" printed in the card slot 500, so as to distinguish the normal equipment from the faulty equipment, and the maintenance personnel can quickly find the faulty equipment, thereby improving the work efficiency.

[0057] In some embodiments, referring to Figs. 4 and 5, the actuator 410 includes a connecting rod 411 and a moving pin 412 connected to the connecting rod 411. Figure 2 and Figure 4 The connecting rod 411 and the moving pin 412 have an included angle therebetween.

[0058] Part of the connecting rod 411 extends into the card slot 500 through the avoiding hole 210, and the moving pin 412 is used to abut against or disengage from the locking member 420.

[0059] Specifically, part of the connecting rod 411 extends into the card slot 500 through the avoiding hole 210. When the horizontal bar 300 is inserted into the card slot 500, the horizontal bar 300 applies an external force to the connecting rod 411, drives the connecting rod 411 to rotate in the +X direction shown by the arrow in Fig. 4, and thus the connecting rod 411 drives the moving pin 412 to rotate synchronously until the connecting rod 411 extends out of the card slot 500, at which time the moving pin 412 abuts against the locking member 420. Figure 2 or Figure 4 Specifically, part of the connecting rod 411 extends into the card slot 500 through the avoiding hole 210. When the horizontal bar 300 is inserted into the card slot 500, the horizontal bar 300 applies an external force to the connecting rod 411, drives the connecting rod 411 to rotate in the +X direction shown by the arrow in Fig. 4, and thus the connecting rod 411 drives the moving pin 412 to rotate synchronously until the connecting rod 411 extends out of the card slot 500, at which time the moving pin 412 abuts against the locking member 420.

[0060] When the horizontal bar 300 is pulled out of the card slot 500, the connecting rod 411 loses the external force, and the connecting rod 411 and the moving pin 412 rotate in the -X direction shown by the arrow in Fig. 5 until the connecting rod 411 returns to the initial state, at which time the moving pin 412 disengages from the locking member 420. Figure 2 or Figure 4 When the horizontal bar 300 is pulled out of the card slot 500, the connecting rod 411 loses the external force, and the connecting rod 411 and the moving pin 412 rotate in the -X direction shown by the arrow in Fig. 5 until the connecting rod 411 returns to the initial state, at which time the moving pin 412 disengages from the locking member 420.

[0061] It should be noted that the included angle between the connecting rod 411 and the moving pin 412 can be 120° to 150°, and the embodiments of the present application do not make too many limitations thereon.

[0062] In some embodiments, referring to Figs. 4 and 5, the actuator 410 further includes a resilient member 413 connected between the moving pin 412 and the second door body 20. Figure 2 and Figure 4 The resilient member 413 can be deformed under the action of an external force and return to the original state after the external force is removed.

[0063] It should be noted that the resilient member 413 can be deformed under the action of an external force and return to the original state after the external force is removed.

[0064] In practical implementation, one end of the elastic element 413 can be connected to the second door body 20, and the other end of the elastic element 413 can be connected to the movable pin 412. When the crossbar 300 is inserted into the slot 500, the crossbar 300 applies an external force to the connecting rod 411, thereby driving the connecting rod 411 along... Figure 2 or Figure 4 When the middle arrow indicates rotation in the +X direction, the connecting rod 411 drives the moving pin 412 to rotate synchronously, thereby the moving pin 412 applies a force to the elastic element 413 connected to it, causing the elastic element 413 to be stretched and deformed.

[0065] When the crossbar 300 is pulled out of the slot 500, the connecting rod 411 loses the contact of the crossbar 300, so that the elastic element 413 loses the external force. Under the action of the elastic restoring force, the elastic element 413 restores its deformation, thereby driving the moving pin 412 along... Figure 2 or Figure 4 Rotating in the X direction as indicated by the middle arrow causes the moving pin 412 to drive the connecting rod 411 to rotate synchronously, so that part of the connecting rod 411 can re-extend into the slot 500.

[0066] It should also be noted that the elastic element 413 can be a spring. When the spring is stretched by an external force, it will deform. This deformation is reversible within the elastic limit, that is, when the external force is removed, the spring can return to its original length. The elastic element 413 can also be other components. This application embodiment does not impose too many restrictions on the type of elastic element 413.

[0067] In some embodiments, refer to Figure 2 and Figure 4 As shown, the locking member 420 includes a locking section 421 and an operating section 422 disposed on one side of the locking section 421. The operating section 422 drives the locking section 421 to rotate relative to the second door body 20 so that the locking section 421 abuts or disengages from the first door body 10.

[0068] In a specific implementation, the operating section 422 can be a knob set on the locking section 421 or a handle set on one side of the locking section 421. The operating section 422 can also be other structures. This application embodiment does not impose too many restrictions on the structure of the operating section 422.

[0069] It should be noted that a keyhole and a lock cylinder can be provided on the operating section 422. By inserting and rotating the key, the locking section 421 can be driven to rotate relative to the second door body 20, which further improves security.

[0070] In some embodiments, refer to Figure 1 and Figure 3 As shown, the slot of the card slot 500 faces the top of the electrical cabinet.

[0071] It can be understood that the upward slot of the card slot 500 can make the plug-in crosspiece 300 more convenient, reduce the operation difficulty, and the upward slot design can avoid the crosspiece 300 from falling off accidentally, because the gravity can make the crosspiece 300 more stably fixed in the card slot 500.

[0072] In some embodiments, referring to Figure 1 and Figure 3 , the third frame 600 is further provided, one of the first frame 100 and the second frame 200 is rotatably connected to the first end of the third frame 600, and the other is detachably connected to the second end of the third frame 600, so as to close or open the slot.

[0073] It can be understood that by setting the third frame 600 to close the slot, the crosspiece 300 inserted in the card slot 500 can be fixed to prevent the crosspiece 300 from being separated from the card slot 500.

[0074] In specific implementation, the first end of the third frame 600 can be connected to the first frame 100 through a rotating shaft, and the third frame 600 rotates along the +X direction shown by the arrow in Figure 2 or Figure 4 , until the second end is connected to the second frame 200, so as to close the slot; the second frame 200 rotates along the -X direction shown by the arrow in Figure 2 or Figure 4 , so that the second end is separated from the second frame 200, until the slot is opened.

[0075] The first end of the third frame 600 can be connected to the second frame 200 through a rotating shaft, and the third frame 600 rotates along the -X direction, until the second end is connected to the first frame 100, so as to close the slot; the second frame 200 rotates along the +X direction, so that the second end is separated from the first frame 100, until the slot is opened. The above setting mode is not shown in the drawings.

[0076] In some embodiments, referring to Figure 1 , the second end is provided with an abutting portion 610.

[0077] It can be understood that by providing the abutting portion 610 on the second end of the third frame 600, the abutting portion 610 is used to abut against the second frame 200 or the first frame 100, which can prevent the second end from being separated from the second frame 200 or the first frame 100, avoid the third frame 600 from loosening during the use of closing the slot, and improve the reliability of the third frame 600.

[0078] In some embodiments, referring to Figure 2 and Figure 4As shown, the locking device of the double-door electrical cabinet further comprises an alarm assembly 700, the alarm assembly 700 comprising a sensing member 710 and an alarm member 720, both of which are arranged on the second door body 20.

[0079] The sensing member 710 is configured to trigger the alarm member 720 to issue an alarm prompt when the locking member 420 is in abutment with the first door body 10, the crosspiece 300 is inserted into the clamping groove 500, and the acting member 410 is in abutment with the locking member 420.

[0080] Specifically, when the locking member 420 is in abutment with the first door body 10, the first door body 10 and the second door body 20 are in a closed state. When the equipment in the double-door electrical cabinet is in a normal live operating state, the crosspiece 300 is inserted into the clamping groove 500 to make the acting member 410 in abutment with the locking member 420. At this time, the sensing member 710 senses the connecting rod 411 and triggers the alarm member 720 to issue an alarm prompt to remind the maintenance personnel that the electrical cabinet is in a live operating state, thereby preventing the maintenance personnel from entering by mistake and improving safety and avoiding safety hazards.

[0081] It should be noted that the sensing member 710 can be an infrared sensor or other sensors, and the present application does not make too many limitations on this.

[0082] In some embodiments, with reference to Figure 2 As shown, the alarm member 720 is at least one of a warning light and a loudspeaker.

[0083] It should be noted that the working principle of the warning light is mainly based on electro-optical conversion, that is, the light source is driven to emit light by electric energy, thereby providing a visual alarm. The working principle of the loudspeaker is mainly based on electro-acoustic conversion, that is, the diaphragm of the loudspeaker is driven to vibrate by an electric signal, thereby generating a sound wave and providing an audible alarm.

[0084] In specific implementation, only the warning light can be provided, only the loudspeaker can be provided, or both the warning light and the loudspeaker can be provided, as long as a good reminding effect can be achieved, and the present application does not make too many limitations on this.

[0085] The present application further provides a double-door electrical cabinet, comprising an electrical cabinet body and a locking device of the double-door electrical cabinet arranged on the electrical cabinet body.

[0086] The specific structure and working mode of the locking device of the double-door electrical cabinet are described in detail in the above embodiments, and will not be repeated here.

[0087] The skilled in the art can understand that the locking device of the double-door electrical cabinet and the double-door electrical cabinet provided by the embodiments of the present application, the double-door electrical cabinet has a first door body 10 and a second door body 20, and the locking device of the double-door electrical cabinet is provided with a first frame 100, a second frame 200, a crosspiece 300 and a locking assembly 400. The first frame 100 and the second frame 200 are arranged on the first door body 10 and the second door body 20 respectively, and the first frame 100 and the second frame 200 are symmetrically arranged and jointly form a clamping groove 500. The crosspiece 300 is detachably inserted into the clamping groove 500. When the normal equipment is in the running state, the crosspiece 300 is inserted into the clamping groove 500. When the operating personnel find the fault equipment, the crosspiece 300 on the electrical cabinet where the fault equipment is located is pulled out, so that the electrical cabinet of the fault equipment and the normal equipment are distinguished, thereby solving the problem that the maintenance personnel cannot easily find the fault equipment.

[0088] The locking assembly 400 includes an acting piece 410 and a locking piece 420, and the acting piece 410 and the locking piece 420 are rotationally connected with the second door body 20. When the locking piece 420 abuts against the first door body 10 and the crosspiece 300 is inserted into the clamping groove 500, the acting piece 410 abuts against the locking piece 420 to prevent the locking piece 420 from rotating, so as to lock the first door body 10 and the second door body 20, thereby preventing the maintenance personnel from entering the electrical cabinet of the normal equipment and avoiding the safety hazard. When the crosspiece 300 is pulled out of the clamping groove 500, the acting piece 410 and the locking piece 420 are disengaged, and the locking piece 420 can be rotated, so that the first door body 10 and the second door body 20 are unlocked.
