Description

Technical Field

[0001] The invention belongs to the technical field of switch cabinets, and in particular relates to a cabinet door interlocking device and a switch cabinet using the cabinet door interlocking device. Background Art

[0002] In order to improve the safety of switch cabinet use, when designing switch cabinets, it is usually required that the switches (such as disconnectors and trolleys) on the middle partition cannot be closed when the switch cabinet door is open, and the switch closing operation can only be performed after the switch cabinet door is closed. To achieve this purpose, a through hole for the handle to pass through is usually opened on the cabinet door, and the through hole corresponds to the switch operating shaft of the switch. The staff can only pass the handle through the through hole and cooperate with the switch operating shaft after closing the cabinet door to close the switch.

[0003] In the prior art, an active part (such as an active rod) is installed on the door of the switch cabinet, and a transmission shaft is rotatably installed on the switch along an axis extending up and down. A shielding plate for shielding the switch operating shaft is provided at one end of the transmission shaft, and a transmission plate for cooperating with the above-mentioned active part is provided at the other end. At the same time, a spring is provided between the shielding plate and the switch to drive the shielding plate to rotate in the direction of shielding the switch operating shaft. When the cabinet door is opened, the shielding plate blocks the switch operating shaft under the drive of the spring, and the operator cannot perform the closing operation; when the cabinet door is closed, the active part on the cabinet door will push the transmission plate to rotate the transmission shaft, and then the transmission shaft will drive the shielding plate to rotate in the direction of clearing the switch operating shaft, and the switch operating shaft can correspond to the perforation on the cabinet door, and then the subsequent closing operation can be performed. Among them, the shielding plate constitutes the shielding part on the transmission shaft, and the transmission plate constitutes the transmission part on the transmission shaft.

[0004] The problem with the current structure is that when the cabinet door is far from the switch, in order to ensure that the active part can touch the transmission part when the cabinet door is closed, the distance of the active part needs to be lengthened. However, after the length of the active part is increased, the longer active part has a larger turning radius, which is not only inconvenient for opening and closing the cabinet door, but also easy to cause damage to various components in the switch cabinet during the process of opening and closing the cabinet door. In addition, when the cabinet door is in the open state, since the active part is long and exposed, it is easy to injure the operator, posing a threat to the operator's safety. Summary of the invention

[0005] The object of the present invention is to provide a cabinet door interlocking device to solve the technical problems in the prior art that when the distance between the cabinet door and the switch is far, the lengthened active parts are likely to cause inconvenience in opening or closing the switch cabinet door and the active parts are likely to injure the operator; the object of the present invention is also to provide a switch cabinet to solve the above-mentioned technical problems.

[0038] The present invention is further described in detail below in conjunction with embodiments.

[0039] Embodiment 1 of the cabinet door interlocking device of the present invention:

[0040] like Figure 4 As shown, the cabinet door interlock device is installed between the cabinet door 100 of the switch cabinet and the switch 120 in the switch cabinet. Figure 1 and Figure 3 As shown, the cabinet door interlock device includes a transmission shaft installed on the switch, wherein the transmission shaft is a rotating shaft 60 rotatably installed on the switch, one end of the rotating shaft 60 is provided with a shielding portion for shielding the switch operating shaft 90, and the other end of the rotating shaft 60 is provided with a transmission portion. In this embodiment, the shielding portion is composed of a separate shielding plate 70, and the transmission portion is composed of a separate transmission plate 80.

[0041] like Figure 1 and Figure 2 As shown, the cabinet door interlocking device also includes a base 10 for installation on the middle partition 110 in the switch cabinet, and a first bracket 11 and a second bracket 12 are installed on the top surface of the base 10, and the first bracket 11 and the second bracket 12 are arranged in sequence in a direction away from the cabinet door 100. A push rod 20 is installed on the base 10 through the first bracket 11 and the second bracket 12, and the push rod 20 passes through the first bracket 11 and the second bracket 12 in sequence. The push rod 20 has a force-bearing end for pushing and cooperating with the active member 130 installed on the cabinet door 100, that is, the force-bearing end of the push rod 20 is an end close to the cabinet door 100 of the switch cabinet, and a force-bearing plate 21 is arranged on the force-bearing end of the push rod 20, and the plate surface of the force-bearing plate 21 is perpendicular to the guiding direction of the push rod 20. The force-bearing plate 21 is pushed by the active member 130 on the cabinet door 100. In this way, when the cabinet door 100 of the switch cabinet is closed, the push rod 20 can be moved in a direction away from the cabinet door 100 of the switch cabinet by pushing the force-bearing plate 21 by the active member 130.

[0042] like Figure 1 and Figure 2As shown, a third bracket 13 is also installed on the top surface of the base 10, and the third bracket 13 and the second bracket 12 are arranged at intervals along a direction perpendicular to the movement of the push rod 20. A push rod 40 is guided and installed in the third bracket 13. The push rod 40 and the push rod 20 are arranged at intervals along a direction perpendicular to the movement of the push rod 20, and the push rod 40 and the push rod 20 extend in parallel. The parallel extension here does not limit the push rod 40 and the push rod 20 to be parallel, as long as both extend along the depth direction of the cabinet as a whole.

[0043] like Figure 1 and Figure 2 As shown, a reversing component is provided between the push rod 20 and the push rod 40. In the present embodiment, the reversing component is a lever 30, which is rotatably mounted on the base 10 via a pin 50, and the lever 30 has an active arm hinged to the push rod 20 and a driven arm hinged to the push rod 40, so that the push rod 20 moving in a direction away from the cabinet door 100 of the switch cabinet can indirectly drive the push rod 40 to move in a direction toward the cabinet door 100 of the switch cabinet through the lever 30, that is, the lever 30 can realize the reversal of the moving direction between the push rod 20 and the push rod 40.

[0044] like Figure 1 As shown, since the transmission plate 80 arranged at the other end of the rotating shaft 60 is located between the cabinet door 100 of the switch cabinet and the push rod 40 in the direction of movement of the push rod 40, and the push rod 40 and the transmission plate 80 push and cooperate, the push rod 40 moving toward the cabinet door 100 of the switch cabinet will push the transmission plate 80 to rotate the rotating shaft 60, and the rotation of the rotating shaft 60 will drive the shielding plate 70 to rotate in the direction of clearing the switch operating shaft 90, and when the cabinet door 100 of the switch cabinet is fully closed, the shielding plate 70 blocking the switch operating shaft 90 is fully opened. At this time, the handle can pass through the through hole on the cabinet door 100 (not shown in the figure) and cooperate with the switch operating shaft 90 to drive the switch operating shaft 90 to close the switch. Moreover, since the transmission plate 80 is located between the cabinet door 100 and the top rod 40 in the moving direction of the top rod 40, when the switch is installed into the cabinet through the cabinet door 100, the top rod 40 will not interfere with or affect the transmission plate 80, so that the transmission plate 80 can be installed in the cabinet together with the switch.

[0045] The push rod 40 is provided with a push rod reset spring installation position 41 located between the push rod 40 and the third bracket 13, and a push rod reset spring (not shown in the figure) is installed on the push rod reset spring installation position 41, that is, the push rod reset spring is located between the push rod 40 and the third bracket 13, and the push rod reset spring here is a compression spring. When the cabinet door 100 of the switch cabinet is opened, the push rod 40 can be driven to move in the direction away from the cabinet door 100 of the switch cabinet by the action of the push rod reset spring, and the lever 30 can be reversed to make the push rod 20 indirectly drive to move in the direction of the cabinet door 100 of the switch cabinet, thereby completing the reset of the cabinet door interlocking device. Figure 4As shown, a push rod return spring 140 is provided between the push rod 20 and the second bracket 12. The push rod return spring 140 is sleeved on the push rod 20, and the two ends of the push rod return spring 140 are respectively pressed into engagement with the second bracket 12 and a pin shaft (not marked in the figure) plugged into the push rod 20. In this way, when the cabinet door 100 of the switch cabinet is opened, the cabinet door interlocking device can also be reset by the push rod return spring 140, and the joint action of the push rod return spring 140 and the push rod return spring can also prevent the hinges between the lever 30 and the push rod 40 and the push rod 20 from being stuck, thereby further ensuring the normal use of the cabinet door interlocking device.

[0046] In fact, if Figure 4 As shown, in this embodiment, a tension spring 150 is connected between the shielding plate 70 and the switch 120, and the tension spring 150 drives the shielding plate 70 to rotate in the direction of shielding the switch operating shaft 90. That is, when the transmission plate 80 is not pushed, the shielding plate 70 will automatically shield the switch operating shaft 90. Figure 1 As shown, in this embodiment, the shielding plate 70 and the transmission plate 80 are located on the same side of the rotating shaft 60. It should be noted that the same side in this embodiment is not strictly the same circumferential position, as long as both can swing towards and away from the cabinet door at the same time when swinging.

[0047] The cabinet door interlock device of the present invention is provided, so that when the cabinet door is closed, the active member will push the push rod to move in the direction away from the cabinet door, and the push rod drives the push rod to move in the direction where the cabinet door is located through the reversing component. The movement of the push rod will push the transmission plate arranged on the rotating shaft to rotate the rotating shaft, and then the rotating shaft will drive the shielding plate arranged on the rotating shaft to rotate in the direction of opening the switch operating shaft, that is, after the cabinet door of the switch cabinet is closed, the switch operating shaft can be moved away so that the handle can pass through the perforation on the cabinet door to twist the switch operating shaft. Compared with the prior art, the active member in the present invention does not need to directly push the transmission part, that is, the active member does not need to be set too long, which not only facilitates the opening or closing of the cabinet door, so that the active member will not cause damage to the parts in the cabinet body when the cabinet door is opened or closed, and the cabinet door will not knock the operator when it is in the open state, thereby ensuring the safety of the operator's operation. At the same time, because the transmission plate is located between the push rod and the cabinet door, when the switch is pushed inward from the cabinet door, the transmission plate pushed in with the switch will not be interfered and affected by the push rod, so that it can be pushed into place smoothly.

[0048] In this embodiment, the tension spring between the shielding plate 70 and the switch 120 forms an elastic reset member. In fact, the elastic reset member can also be a torsion spring installed outside the transmission shaft.

[0049] Embodiment 2 of the cabinet door interlocking device of the present invention:

[0050] The difference between this embodiment and embodiment 1 is that in embodiment 1, a force plate 21 is provided on the force-bearing end of the push rod 20, that is, the push rod 20 is pushed by the active member 130 installed on the cabinet door 100 of the switch cabinet to push the force plate 21 to complete the pushing action of the push rod 20. In this embodiment, the force plate 21 is eliminated, and the force-bearing end on the push rod 20 is only one end surface of the push rod 20.

[0051] Embodiment 3 of the cabinet door interlocking device of the present invention:

In the present embodiment, the push rod reset spring is eliminated, and after the cabinet door 100 of the switch cabinet is opened, the cabinet door interlocking device is directly reset manually; or the cabinet door interlocking device is reset by relying on the elastic reset member between the switch and the shielding plate 70.

[0053] Embodiment 4 of the cabinet door interlocking device of the present invention:

[0054] The difference between this embodiment and the first embodiment is that in the first embodiment, the reversing component is a lever 30 rotatably mounted on the base 10, and the two ends of the lever 30 are respectively connected to the push rod 20 and the push rod 40.
