Furthermore, it is possible to specify that a chassis trolley of a switch cabinet can only be operated if the other chassis trolley is in one of the positions, which prevents the chassis trolleys from being mixed up.

[0078] As Figures 1 to 7 shown, a schematic diagram of the interlocking mechanism for chassis trolleys of switch cabinets according to the present application. The interlocking mechanism is used for two chassis trolleys. In order to distinguish between the two chassis trolleys, the following are referred to as first chassis trolley and second chassis trolley, respectively. The first chassis trolley comprises a first front beam 11, a first moving assembly 12 and a first screw 13, the rotation of which is able to move the first moving assembly 12 between a test position and a working position, the first front beam 11 comprises a first handle operating plate 111, the first handle operating plate 111 is provided with a first operating hole 1111, a handle (not shown in the figure) of the first chassis trolley can be inserted into the first operating hole 1111 and fixed to the first screw 13, and a worker can rotate the handle to drive the first screw 13 to rotate. The second chassis trolley comprises a second front beam, a second moving assembly 22 and a second screw 23, the rotation of which is able to move the second moving assembly 22 between a test position and a working position, the second front beam comprises a second handle operating plate 211, the second handle operating plate 211 is provided with a second operating hole 2111, a handle of the second chassis trolley can be inserted into the second operating hole 2111 and fixed to the second screw 23, and a worker can rotate the handle to drive the second screw 23 to rotate.

[0079] The interlocking mechanism comprises two locking mechanisms and a key 4, and the two locking mechanisms are a first locking mechanism and a second locking mechanism, respectively. The first locking mechanism is used for the first chassis trolley, and the second locking mechanism is used for the second chassis trolley. The first locking mechanism comprises a first lock body and a first interlocking assembly, and the second locking mechanism comprises a second lock body and a second interlocking assembly.

[0080] As an exemplary illustration, as Figures 1 to 4 shown, the first lock body can be rotated clockwise or counterclockwise to rotate between the first position and the second position. Figure 1 and Figure 2 shown, the first lock body is in the first position, the key 4 can be pulled out of the first lock body, Figure 3 and Figure 4 shown, the first lock body is in the second position, the key 4 cannot be pulled out of the first lock body, i.e. only when the key 4 is in the first position, the key 4 can be pulled out of the first lock body.

[0081] The first interlocking assembly is arranged on the first front beam 11, and the rotation of the first lock body can drive the first interlocking assembly to move between the third position and the fourth position. Figure 1 and Figure 2 As shown in the first position of the first lock body, the first interlocking assembly is in the third position, and the first moving assembly 12 of the first chassis vehicle is locked in the test position. Figure 3 and Figure 4 As shown in the second position of the first lock body, the first interlocking assembly is in the fourth position, and the first chassis vehicle can move between the test position and the working position.

[0082] The second lock body can rotate between the fifth position and the sixth position. As an example, as shown in the fifth position of the second lock body, Figures 5 to 7 the second lock body can be rotated clockwise or counterclockwise to rotate between the fifth position and the sixth position. Figure 5 and Figure 6 As shown in the fifth position of the second lock body, Figure 6 As shown in the sixth position of the second lock body.

[0083] The second interlocking assembly is arranged on the second front beam, and the rotation of the second lock body can drive the second interlocking assembly to move between the seventh position and the eighth position. When the second lock body is in the fifth position, the second interlocking assembly is in the seventh position, and the second moving assembly 22 of the second chassis vehicle is locked in the working position. When the second lock body is in the sixth position, the second interlocking assembly is in the eighth position, and the second chassis vehicle can move between the test position and the working position.

[0084] The key 4 can be inserted into the first lock body to enable the rotation of the first lock body, and can be inserted into the second lock body to enable the rotation of the second lock body. When the first lock body is in the first position, the key 4 is in a state that can be pulled out, and when the second lock body is in the fifth position, the key 4 is in a state that can be pulled out. That is, for the first chassis vehicle, only when the first lock body is in the first position, the key 4 can be pulled out, at which time the first chassis vehicle is locked in the test position, as shown in Figure 1 and Figure 2 For the second chassis vehicle, only when the second lock body is in the second position, the key 4 can be pulled out, at which time the second chassis vehicle is locked in the working position, as shown in Figure 5 and Figure 6 .

[0085] According to the present application, by providing the first locking mechanism, the second locking mechanism, and the key 4 capable of operating the first locking mechanism and the second locking mechanism, it is realized that when one chassis vehicle is locked in a specific position, the other chassis vehicle can be operated, which can avoid the error operation of the chassis vehicle and cause personal safety.

[0086] As an example, the first lock body and the second lock body each include a pin shaft 31 and a lock cylinder 32. The pin shaft 31 is movable and fixed to the first interlocking assembly or the second interlocking assembly; the key 4 can be inserted into the lock cylinder 32 and drive the lock cylinder 32 to rotate, and the rotation of the lock cylinder 32 can drive the pin shaft 31 to move. More specifically, for the first lock body and the second lock body, the position of the lock cylinder 32 is taken as the position of the first lock body or the second lock body. In this way, the rotation of the lock cylinder 32 can drive the pin shaft 31 to move in the first direction and the reverse direction of the first direction, and in turn drive the first interlocking assembly or the second interlocking assembly to move in the first direction and the reverse direction of the first direction, so as to reach the corresponding position. Optionally, the first lock body and the second lock body each further include a housing 33, a part of the lock cylinder 32 is located in the housing 33, and the pin shaft 31 is arranged through the housing 33. The structure of such first lock body and second lock body can convert the rotation movement into linear movement, and the structure is simple and easy to realize.

[0087] The following is an example of the first chassis vehicle and the second chassis vehicle being arranged in the same direction. In the following example, the first direction, the second direction and the third direction are perpendicular to each other. The third direction is the direction of moving from the test position to the working position.

[0088] As an example, the first interlocking assembly includes a first moving plate 51 and a first pushing piece.

[0089] As shown in Figures 1 to 4 , in the case of rotation of the first lock body, the first moving plate 51 can move between the third position and the fourth position, the first moving plate 51 has a first waist hole, the first waist hole includes a first hole 511 and a second hole 512 which are in communication with each other, and in the case of the first moving plate 51 being at the third position, the first moving plate 51 can block the rotation of the first screw rod 13, and in the second direction, the height of the first hole 511 is less than the height of the second hole 512. Figure 1 and Figure 2 , the first lock body is at the first position, the first interlocking assembly is at the third position, and the first moving assembly 12 is locked at the test position. Figure 3 and Figure 4 , the first lock body is at the second position, the first interlocking assembly is at the fourth position, and the first moving assembly 12 can move between the test position and the working position.

[0090] The first pushing member comprises a middle part 522 and a special-shaped part 521 connected with each other, the middle part 522 is movable in the first hole 511 and the second hole 512, and the special-shaped part 521 is movable in the second hole 512. When the first moving plate 51 is in the third position, the middle part 522 is in the first hole 511; when the first moving plate 51 is in the fourth position and the first chassis vehicle is away from the test position, the first pushing member is in the second hole 512. From Figures 1 to 4 As shown in the figure, the height of the special-shaped part 521 in the second direction is greater than that of the middle part 522. In this way, the special-shaped part 521 can only move in the second hole 512, and the middle part 522 can move in the first hole 511 and the second hole 512. The movement here can include movement in the first direction and the third direction. The movement in the first direction refers to relative movement, that is, in practice, the first moving plate 51 moves while the first pushing member is stationary. The first pushing member can be fixed to the first front beam 11. In the third direction, the special-shaped part 521 can pass through the second hole 512, but cannot pass through the first hole 511, and the middle part 522 can pass through the first hole 511 and the second hole 512. Figures 1 to 4 Only one example of the special-shaped part 521 is shown, which is convenient for processing, and other shapes of the special-shaped part 521 can also be used, as long as it can only move in the second hole 512. Similarly, the middle part 522 can also be of any shape, as long as it can move in the first hole 511 and the second hole 512, and can be set according to actual needs. Such a structure is relatively simple to implement and has low cost.

[0091] Optionally, the first locking mechanism further comprises a first reset member 53, which is used to make the special-shaped part 521 be in the second hole 512 to block the first moving plate 51 from moving to the fourth position when the first moving assembly 12 is away from the test position. As shown in the figure, Figures 1 to 4As shown, the first reset member 53 can be a spring. During the movement of the first moving assembly 12 from the test position to the working position, the first reset member 53 can provide a reset force to the first pushing member, so that the first pushing part moves along the third direction, and then the special-shaped part 521 is located in the second hole 512, so that the first moving plate 51 is prevented from moving to the fourth position, and then the first moving plate 51 can be kept at the third position, so that the first lock body is also locked at the first position, the key 4 cannot be pulled out, and then the staff cannot use the key 4 to operate other chassis vehicles. During the movement of the first moving assembly 12 from the working position to the test position, pressure is applied to the first reset member 53, the first reset member 53 stores energy, and then applies a reset force to the first pushing member. During the movement of the first moving assembly 12 from the working position to the test position, the first pushing member is finally pushed to move in the opposite direction of the third direction, and then the intermediate part 522 is located in the second hole 512 to unlock the first moving plate 51, so that the first moving plate 51 can move in the opposite direction of the first direction. The first reset member 53 is used to realize the automatic reset of the first pushing member, which is simple in structure and convenient and fast. The first reset member 53 can be a spring.

[0092] Optionally, the first pushing member further comprises a first body 523 and a first column 524. The first body 523 is connected to the intermediate part 522 and is hollow. The first column 524 is arranged in the first body 523 and fixed on the first front beam 11. The first reset member 53 is sleeved on the first column 524 and arranged in the first body 523. Such a structure is very simple, easy to realize and low in cost. The first body 523, the intermediate part 522 and the special-shaped part 521 can be integrally formed, and the three can be integrally formed with the first column 524.

[0093] Optionally, the first front beam 11 comprises a first handle operation plate 111, and the first handle operation plate 111 has a first operation hole 1111. The first handle operation plate 111 can move in the third direction to enable the handle to operate the first screw rod 13 to rotate. The first moving plate 51 blocks the movement of the handle operation plate in the third direction to lock the first moving assembly 12 at the test position. Figure 1 and Figure 2 As shown, it is a structure schematic view of the first moving plate 51 located on the movement path of the first handle operation plate 111. Figure 3 and Figure 4 As shown, it is a structure schematic view of the first moving plate 51 not blocking the first handle operation plate 111. The first moving assembly 12 is locked at the test position by blocking the movement of the handle operation plate by the first moving plate 51, which is simple in structure and high in reliability.

[0094] Optionally, the second interlocking assembly comprises a second moving plate 61 and a shaft rod.

[0095] Wherein, the second moving plate 61 is capable of moving between a seventh position and an eighth position in the case that the second lock body rotates, the second moving plate 61 has a second waist hole comprising a third hole 611 and a fourth hole 612 which are in communication with each other, the second moving plate 61 is capable of impeding the rotation of the second screw rod 23 in the case that the second moving plate 61 is located at the seventh position, the height of the third hole 611 is less than the height of the fourth hole 612 in the second direction. The second screw rod 23 is capable of rotating and further driving the second moving assembly 22 to move between the working position and the testing position in the case that the second moving plate 61 is located at the eighth position. One end of the second moving plate 61 is fixed to the second lock body, specifically to the pin shaft 31 of the second lock body. In this way, the rotation of the lock cylinder 32 in the second lock body is capable of driving the second moving plate 61 to move.

[0096] The shaft rod has a rod body 621 and an annular protruding part 622 located on the rod body 621, the first end of the rod body 621 is capable of moving in the third hole 611 and the fourth hole 612, the second end of the rod body 621 is capable of penetrating the second moving assembly 22, the outer diameter of the annular protruding part 622 is greater than the height of the third hole 611 and less than the height of the fourth hole 612, and the rod body 621 and the annular protruding part 622 can be integrally formed. In the case that the second moving plate 61 is located at the seventh position, the rod body 621 is located in the third hole 611, and in the case that the second moving plate 61 is located at the eighth position and the second chassis vehicle leaves the working position, the annular protruding part 622 is located in the fourth hole 612 to block the second moving plate 61 from moving to the seventh position. As shown in Figure 5 and Figure 6 The cross section of the rod body 621 can be circular with a diameter less than the third hole 611 and the fourth hole 612, and the rod body 621 is capable of moving in the third hole 611 and the fourth hole 612. The outer diameter of the annular protruding part 622 is greater than the third hole 611 and less than the fourth hole 612, so that the annular protruding part 622 can only move in the fourth hole 612. In the case that the annular protruding part 622 is located in the fourth hole 612, the second moving plate 61 cannot move from the eighth position to the seventh position, so that the second lock body remains in the sixth position, the key 4 cannot be pulled out, and further the staff cannot operate the first chassis vehicle with the key 4. Such a second interlocking assembly has a simple structure and is easy to process. Similarly, the movement here can include movement in the first direction and movement in the third direction.

[0097] Optionally, the second locking mechanism further comprises a second reset member for enabling the annular protrusion 622 to be located in the fourth hole 612 to block the second moving plate 61 from moving to the seventh position when the second moving assembly 22 leaves the working position. When the second moving assembly 22 leaves the working position, the shaft rod will move along the third direction due to the action of the second reset member, and then the annular protrusion 622 is located in the fourth hole 612. In this way, the second moving plate 61 cannot move to the seventh position, and then the second lock body cannot rotate to the fifth position, so that the key 4 cannot be pulled out and the staff cannot operate other chassis vehicles with the key 4. The second reset member is used to realize the automatic reset of the shaft rod, which is simple in structure and convenient and fast. The second reset member can be a spring.

[0098] Optionally, the second interlocking assembly comprises a first stop member 64 and a second stop member 65. The second reset member is sleeved on the rod body 621, and the second reset member is located between the first stop member 64 and the annular protrusion 622. The second stop member 65 is fixed to one end of the rod body 621 away from the annular protrusion 622, and the rod body 621 is movably arranged in the second stop member 65. During the movement of the second moving assembly 22 to the working position, the second moving assembly 22 can contact the second stop member 65 to drive the rod body 621 to move along the third direction, and then the annular protrusion 622 is away from the fourth hole 612. As an example, the first stop member 64 is an L-shaped plate, and the first stop member 64 is fixed on the second front beam. When the second moving assembly 22 is in the working position, the second moving assembly 22 will move the shaft rod in the second waist hole due to the pulling of the second stop member 65, as shown in Figures 5 to 7 Figure 5 and Figure 6 When the second moving assembly 22 leaves the working position, the second moving assembly 22 no longer applies force to the shaft rod through the second stop member 65, and due to the action of the second reset member, the shaft rod moves along the third direction in the opposite direction, and then the annular protrusion 622 is located in the fourth hole 612. During the movement of the second moving assembly 22 from the test position to the working position, the second moving assembly 22 pulls the second stop member 65 to move the shaft rod as a whole along the third direction, and then the annular protrusion 622 is away from the fourth hole 612, and the rod body 621 is located in the fourth hole 612, so that the second moving plate 61 can move from the eighth position to the seventh position.

[0099] ​Optionally, the second front beam includes a second handle operating plate 211 having a second operating hole 2111 therein. The second handle operating plate 211 is movable in a third direction to enable the handle to rotate the second screw rod 23. The second movable plate 61 blocks the movement of the second handle operating plate 211 in the third direction, thereby locking the second movable assembly 22 in the working position. The second handle operating plate 211 moves in the third direction, thereby allowing the handle to be fixed to the second screw rod 23. When a staff member rotates the handle, the second screw rod 23 is rotated, thereby moving the second movable member. Blocking the second handle operating plate 211 by the second movable plate 61 to limit the position of the second movable assembly 22 is relatively simple to implement and highly reliable.

[0100] Optionally, the second locking mechanism further includes a limiter 66 , which is fixed to the rod body 621 to limit the movement distance of the shaft, so that the second reset member can accumulate precise force to enable the annular protrusion 622 to accurately enter the fourth hole 612 .

[0101] Optionally, the second locking mechanism also includes a limiting member 67, which is fixed on the side wall of the second movable component 22, and the rod body 621 is passed through the limiting member 67. Through the limiting member 67, it can further constrain the moving direction of the rod body 621, so that the movement of the rod body 621 is smoother.

[0102] In the above example, the first handle operating plate 111 and the second handle operating plate 211 can be automatically reset. The specific reset method is, for example, to set corresponding reset members, which will not be described in detail. In addition, the first movable plate 51 and the second movable plate 61 can be common parts, that is, the first movable plate 51 and the second movable plate 61 have the same structure, and the corresponding waist holes are used as needed. Figures 1 to 7 1 and 2. It has been shown that the structures of the first movable plate 51 and the second movable plate 61 are the same. Using a common structure can simplify the management of parts.

[0103] The working process of the chassis interlocking mechanism for a switch cabinet of the present invention is described below by way of a specific example. In this example, the first chassis and the second chassis use the same key 4 .

[0104] Assume that Figure 1 and Figure 2 As shown, the first lock body is in the first position, the first movable plate 51 is in the third position, and the first movable plate 51 blocks the first handle operating plate 111 from moving in the third direction, so that the handle of the first chassis cannot be inserted and fixed to rotate the first screw 13, so that the first chassis is locked in the test position. At this time, the first movable component 12 pushes the first body 523, the first reset member 53 accumulates force, and the middle part 522 is located in the first hole 511.Figure 5 and Figure 6 As shown in FIG. 6, the second lock body is in the fifth position, and the second moving plate 61 is in the seventh position, which blocks the second handle operating plate 211 from moving in the third direction, and thus the handle of the second trolley cannot be inserted to fix the second screw rod 23 to rotate, so that the second trolley is locked in the working position, and at this time, the first end of the rod body 621 is located in the third hole 611.

[0105] The staff holds the key 4 and can only operate one of the locking mechanisms to move the trolley.

[0106] Suppose the first locking mechanism is currently operated. The staff inserts the key 4 into the lock cylinder of the first lock body and rotates the first lock body from the first position to the second position, in the process of which the lock cylinder of the first lock body drives the first moving plate 51 to move from the third position to the fourth position, and in the relative movement, the middle part 522 of the first pushing piece gradually moves from the first hole 511 to the second hole 512, and the first moving plate 51 can no longer prevent the first handle operating plate 111 from moving in the third direction, so the handle of the first trolley can be inserted into the first operating hole 1111 and drive the first screw rod 13 to rotate, and the first moving assembly 12 starts to move from the test position to the working position, and the first moving assembly 12 moves away from the first body 523, and the first body 523 moves in the third direction under the action of the first return piece 53, and thus the special-shaped part 521 is located in the second hole 512, at this time, the first moving plate 51 cannot move to the third position and remains in the fourth position, the first lock body remains in the second position, and the key 4 cannot be pulled out, as shown in FIG. 7. Figure 3 and Figure 4

[0107] The staff needs to operate the second trolley, and at this time, the first trolley needs to be restored to the test position so that the key 4 can be pulled out. The staff rotates the handle of the first trolley to move the first moving assembly 12 from the working position to the test position. In the process of moving, the first moving assembly 12 gradually approaches the first body 523 and applies a pushing force to the first body 523 in the opposite direction of the third direction, so that the first body 523 moves in the opposite direction of the third direction, and thus the special-shaped part 521 moves away from the second hole 512, and the middle part 522 enters the second hole 512, so that the first moving plate 51 can move from the fourth position to the third position. At this time, the staff can rotate the lock cylinder of the first lock body to restore the first lock body from the second position to the first position, and the staff can pull out the key 4.

[0108] ​Then, the staff can insert the key 4 into the lock cylinder of the second lock body, and rotate the second lock body from the fifth position to the sixth position, the lock cylinder of the second lock body drives the second moving plate 61 to move from the seventh position to the eighth position, which is relatively displaced with the shaft rod, and the first end of the rod body 621 moves from the third hole 611 to the fourth hole 612. At this time, the second handle operating plate 211 can move along the third direction, and the staff can fix the handle of the second chassis car with the second screw rod 23, and then rotate the second screw rod 23, so that the second moving assembly 22 moves from the working position to the test position, as shown in Figure 7 The second moving assembly 22 gradually leaves the working position, and the force applied to the second stop piece 65 gradually decreases, and under the action of the second return piece, the shaft rod moves in the opposite direction of the third direction, so that the annular protruding part 622 enters the fourth hole 612. At this time, the second moving plate 61 cannot move, and remains in the eighth position. After the second chassis car is repaired, it needs to be restored to the working position. The staff rotates the handle to rotate the second screw rod 23, and then the second moving assembly 22 moves from the test position to the working position. Due to the action of the second moving assembly 22, it applies a force along the third direction to the shaft rod through the second stop piece 65, so that the shaft rod moves in the third direction, and then the annular protruding part 622 leaves the fourth hole 612, and the first end of the rod body 621 reenters the fourth hole 612, at this time the second moving plate 61 can move to the seventh position. In addition, the second return piece is also recharged. The staff can rotate the second lock body, so that it rotates from the fourth position to the third position, and the key 4 can be pulled out.
