Abstract
Description
Technical Field
[0001] This application relates to an interlocking mechanism and a switch cabinet. Background Technology
[0002] In many applications, it is often necessary to interlock between two moving parts so that only one moving part is allowed to move at a time. For example, in a switch cabinet that includes two disconnect switches, it is necessary to allow only one disconnect switch to be operated at a time. Utility Model Content
[0003] This application provides an interlocking mechanism, including:
[0004] The first slide plate is slidably mounted onto a housing in the left-right direction;
[0005] The second slide plate is slidably mounted onto the housing in the left-right direction, and the second slide plate is stacked with the first slide plate;
[0006] A rotating member, rotatably mounted to the housing, is configured to rotate between an initial state, a first blocking state, and a second blocking state. In the initial state of the rotating member, one of the first and second sliding plates is capable of translation. When the first sliding plate translates to the left or right, the first sliding plate is configured to drive the rotating member to the first blocking state, such that the rotating member blocks the translation of the second sliding plate. When the second sliding plate translates to the left or right, the second sliding plate is configured to drive the rotating member to the second blocking state, such that the rotating member blocks the translation of the first sliding plate.
[0007] Advantageously, the rotating member has a first protrusion projecting toward a first sliding plate, the first sliding plate having a first groove corresponding to the first protrusion, the first protrusion being accommodated within the first groove in the initial state.
[0008] Advantageously, the rotating member has a second protrusion projecting toward the second slide plate, the second slide plate having a second groove corresponding to the second protrusion, the second protrusion being accommodated within the second groove in the initial state.
[0009] Advantageously, when the first slide plate moves, the first groove of the first slide plate abuts against the first protrusion, pushing the rotating member to rotate. After the first groove of the first slide plate moves past the first protrusion, the outer wall of the first slide plate applies force to the first protrusion and then to the second protrusion to keep the second protrusion abutting against the second groove, thereby blocking the second slide plate from moving.
[0010] Advantageously, when the second slide plate moves, the second groove of the second slide plate abuts against the second protrusion, pushing the rotating member to rotate. After the second groove of the second slide plate moves past the second protrusion, the outer wall of the second slide plate applies force to the second protrusion and then to the first protrusion to keep the first protrusion abutting against the first groove, thereby blocking the first slide plate from moving.
[0011] Advantageously, it also includes a retaining ring, which is mounted on the rotation axis of the rotating member and configured to prevent the rotating member from moving along the rotation axis.
[0012] This application also provides a switch cabinet, including a first disconnecting switch, a second disconnecting switch, and an interlocking mechanism as described above.
[0013] Advantageously, the first slide is an operating slide for a first disconnecting switch in the switchgear, and the second slide is an operating slide for a second disconnecting switch in the switchgear. Attached Figure Description

[0021] Figure 1 A schematic diagram of the interlocking mechanism according to this application is shown, with the rotating component of the interlocking mechanism in its initial state. The interlocking mechanism includes a first sliding plate 1, a second sliding plate 2, and a rotating component 3. The first sliding plate 1 is mounted on the housing 4 and is capable of translation, for example, sliding left and right as shown in the figure. The second sliding plate 2 is mounted on the housing 4 and is capable of translation, for example, sliding left and right as shown in the figure. The first sliding plate 1 and the second sliding plate 2 are stacked, for example, stacked vertically as shown in the figure. The rotating component 3 is rotatably mounted on the housing and is configured to switch between an initial state, a first blocking state, and a second blocking state.
[0022] exist Figure 1 In the initial state shown, one of the first slide plate 1 and the second slide plate 2 can slide left and right. The rotating member 3 has a first protrusion 31 protruding towards the first slide plate and a second protrusion 32 protruding towards the second slide plate. That is, in the example shown, the position of the first protrusion 31 is higher than the position of the second protrusion 32, thus corresponding to the first slide plate and the second slide plate respectively. A retaining ring 33 is provided on the rotation axis of the rotating member to lock the rotating member 3, so that the rotating member 3 can only rotate and cannot move up and down along the rotation axis.
[0023] The first slide plate 1 has a first groove 11, and the second slide plate 2 has a second groove 21. In the initial state, the first protrusion 31 is accommodated in the first groove 11, and the second protrusion is accommodated in the second groove. At this time, the first protrusion 31 does not exert force on the first groove, and the second protrusion does not exert force on the second groove.
[0024] For example, when the first skateboard 1 moves to the left, as Figure 2 As shown, the first groove 11 of the first sliding plate 1 abuts against the first protrusion 31, pushing the rotating component along... Figure 2Rotate in the direction of the arrow in the diagram. After the first slide plate translates past the first protrusion, the first protrusion 31 abuts against the outer wall 12 of the first slide plate 1, as shown. Figure 2 As shown (with the rotating component in the first blocking state), this causes the first sliding plate to exert a force on the first protrusion 31 and then on the second protrusion 32, causing the second protrusion to abut against the second groove 21 under the action of this force. Thus, the presence of this force prevents the second sliding plate from translating.
[0025] Similarly, when the first slide plate moves to the right, the relationship between the first slide plate, the rotating component, and the second slide plate is similar to the description above. When the first slide plate 1 moves to the right, the first groove 11 of the first slide plate 1 abuts against the first protrusion 31, pushing the rotating component along the... Figure 2 The arrows in the diagram rotate in opposite directions. After the first slide plate translates past the first protrusion, the first protrusion 31 abuts against the outer wall 34 of the first slide plate 1. This causes the first slide plate to exert a force on the first protrusion 31, which in turn exerts a force on the second protrusion 32, causing the second protrusion to abut against the second groove 21 under the action of this force. Thus, the presence of this force prevents the second slide plate from translating.
[0026] When the second slide 2 moves to the right, as Figure 3 As shown, the second groove 21 of the second slide plate 2 abuts against the second protrusion 32, pushing the rotating component along... Figure 3 Rotate in the direction of the arrow. After the second slide plate translates past the second protrusion, the second protrusion 32 abuts against the outer wall 22 of the second slide plate 2, as shown. Figure 3 As shown (the rotating component is in the second blocking state), this causes the second slide plate to exert a force on the second protrusion 32 and then on the first protrusion 31, causing the first protrusion to abut against the first groove 11 under the action of this force. Thus, the presence of this force prevents the first slide plate from translating.
[0027] Similarly, when the second slide plate moves to the left, the relationship between the first slide plate, the rotating component, and the second slide plate is similar to that described above. When the second slide plate 2 moves to the left, the second groove 21 of the second slide plate 2 abuts against the second protrusion 32, pushing the rotating component along the... Figure 3 The arrows in the diagram rotate in opposite directions. After the second slide plate moves past the second protrusion, the second protrusion 32 abuts against the outer wall 22 of the second slide plate 2. This causes the second slide plate to exert a force on the second protrusion 32, which in turn exerts a force on the first protrusion 31, causing the first protrusion to abut against the first groove 11 under the action of this force. Thus, the presence of this force prevents the first slide plate from moving.
[0028] The interlocking mechanism of this application can be used in many applications. For example, the first slide plate 1 is an operating slide plate for the first disconnecting switch in the switchgear, and the second slide plate 2 is an operating slide plate for the second disconnecting switch in the switchgear. In this way, only one disconnecting switch can be operated at a time. Of course, the interlocking mechanism of this application can also be applied to other suitable applications to achieve the goal of allowing only one slide plate to be operated at a time.
