[0076] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail with reference to the following embodiments. Nouns and pronouns related to people in this patent application are not limited to specific genders.

[0077] The inventor proposes an interlocking mechanism for chassis vehicles of switch cabinets, which is used for interlocking chassis vehicles of different switch cabinets, that is, locking a chassis vehicle of a switch cabinet in a test position, and / or locking a chassis vehicle of a switch cabinet in a working position. In addition, it can also be specified that when a chassis vehicle of a switch cabinet is in one of the positions, another chassis vehicle can be operated, so as to prevent the wrong chassis vehicle from entering.

[0078] like Figures 1 to 7 The figure is a schematic diagram of the structure of the interlocking mechanism of the chassis vehicle for the switch cabinet according to the present invention. The interlocking mechanism is used for two chassis vehicles. In order to distinguish the two chassis vehicles, they are respectively referred to as the first chassis vehicle and the second chassis vehicle below. The first chassis vehicle includes a first front beam 11, a first moving assembly 12 and a first screw rod 13. The rotation of the first screw rod 13 can drive the first moving assembly 12 to move between the test position and the working position. The first front beam 11 includes a first handle operating plate 111. The first handle operating plate 111 is provided with a first operating hole 1111. The handle of the first chassis vehicle (not shown in the figure) can be inserted into the first operating hole 1111 and fixed to the first screw rod 13. The staff can drive the first screw rod 13 to rotate by rotating the handle. The second chassis vehicle includes a second front beam, a second movable assembly 22 and a second screw 23. The rotation of the second screw 23 can drive the second movable assembly 22 to move between the test position and the working position. The second front beam includes a second handle operating plate 211. The second handle operating plate 211 is provided with a second operating hole 2111. The handle of the second chassis vehicle can be inserted into the second operating hole 2111 and fixed to the second screw 23. The staff can drive the second screw 23 to rotate by rotating the handle.

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

[0080] The first lock body can rotate between a first position and a second position. Figures 1 to 4 As 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 The first lock body is shown in the first position, and the key 4 can be pulled out from the first lock body. Figure 3 and Figure 4 It shows the situation that the first lock body is located in the second position, and the key 4 cannot be pulled out from the first lock body, that is, the key 4 can be pulled out from the first lock body only when it is located in the first position.

[0081] The first interlocking assembly is used to pass through 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, when the first lock body is in the first position, 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, when the first lock body is located at the second position, the first interlocking assembly is located at the fourth position and the first chassis vehicle can move between the test position and the working position.

[0082] The second lock body can be rotated between a fifth position and a sixth position. As an exemplary illustration, Figures 5 to 7 As shown, 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 The second lock body is shown in the fifth position. Figure 6 The second lock body is shown in the sixth position.

[0083] The second interlocking assembly is used to pass through 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 movable assembly 22 of the second chassis 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 can move between the test position and the working position.

[0084] The key 4 can be inserted into the first lock body so that the first lock body can rotate, and can be inserted into the second lock body so that the second lock body can rotate. When the first lock body is in the first position, the key 4 is in a state where it can be pulled out, and when the second lock body is in the fifth position, the key 4 is in a state where it can be pulled out. That is, for the first chassis vehicle, the key 4 can only be pulled out when the first lock body is in the first position, and at this time the first chassis vehicle is locked in the test position, such as 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, such as Figure 5 and Figure 6 shown.

[0085] According to the present invention, by providing a first locking mechanism, a second locking mechanism and a key 4 capable of operating the first locking mechanism and the second locking mechanism, it is possible to achieve that when a certain chassis vehicle is locked in a specific position, another chassis vehicle can be operated, thereby avoiding personal safety hazards caused by incorrect operation of the chassis vehicles.

[0086] As an exemplary illustration, the first lock body and the second lock body both include the following structures: a pin 31 and a lock core 32. The pin 31 can move and be fixed to the first interlocking assembly or the second interlocking assembly; the key 4 can be inserted into the lock core 32 and drive the lock core 32 to rotate, and the rotation of the lock core 32 can drive the pin 31 to move. More specifically, for the first lock body and the second lock body, the position of the lock core 32 is taken as the position of the first lock body or the second lock body. In this way, the rotation of the lock core 32 can drive the pin 31 to move in the first direction and the opposite direction of the first direction, and then drive the first interlocking assembly or the second interlocking assembly to move in the first direction and the opposite direction of the first direction, so as to reach the corresponding position. Optionally, the first lock body and the second lock body also include a housing 33, a part of the lock core 32 is located in the housing 33, and the pin 31 is penetrated in the housing 33. Such a structure of the first lock body and the second lock body can convert the rotational movement into a linear movement, and its structure is simple and easy to implement.

[0087] The following is an example of the first chassis and the second chassis 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 in which the test position moves toward the working position.

[0088] As an exemplary illustration, the first interlocking assembly includes a first moving plate 51 and a first resisting member.

[0089] like Figures 1 to 4 As shown, when the first lock body rotates, the first movable plate 51 can move between the third position and the fourth position. The first movable plate 51 has a first waist hole, and the first waist hole includes a first hole 511 and a second hole 512 that are connected to each other. When the first movable plate 51 is in the third position, the first movable plate 51 can prevent the first screw rod 13 from rotating. 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 As shown, the first lock body is located in the first position, the first interlocking assembly is located in the third position, and the first moving assembly 12 is locked in the test position. Figure 3 and Figure 4 As shown, the first lock body is located in the second position, the first interlocking assembly is located in the fourth position, and the first moving assembly 12 is able to move between the test position and the working position.

[0090] The first push member includes an intermediate portion 522 and a special-shaped portion 521 connected to each other, the intermediate portion 522 can move in the first hole 511 and the second hole 512, and the special-shaped portion 521 can move in the second hole 512. When the first movable plate 51 is in the third position, the intermediate portion 522 is located in the first hole 511. When the first movable plate 51 is in the fourth position and the first chassis vehicle leaves the test position, the first push member is located in the second hole 512. Figures 1 to 4 As shown, the height of the shaped portion 521 in the second direction is greater than that of the middle portion 522. In this way, the shaped portion 521 can only move along the second hole 512, and the middle portion 522 can move in the first hole 511 and the second hole 512. The movement here may 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 movable plate 51 moves while the first push member does not move. The first push member can be fixed on the first front beam 11. In the third direction, the shaped portion 521 can pass through the second hole 512, but cannot pass through the first hole 511, and the middle portion 522 can pass through the first hole 511 and the second hole 512. Figures 1 to 4 Only one example of the special-shaped portion 521 is shown in the figure, which is convenient for processing. Special-shaped portions 521 of other shapes can also be used as long as they can only move in the second hole 512. Similarly, the middle portion 522 can also be of any shape as long as it can move in both the first hole 511 and the second hole 512. It 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 includes a first reset member 53, which is used to position the special-shaped portion 521 in the second hole 512 to prevent the first movable plate 51 from moving to the fourth position when the first movable assembly 12 leaves the test position. Figures 1 to 4As shown, the first reset member 53 can be a spring. In the process of the first moving assembly 12 moving from the test position to the working position, the first reset member 53 can provide a reset force to the first push member, so that the first push portion moves along the third direction, so that the special-shaped portion 521 is located in the second hole 512, so that the first moving plate 51 can be blocked from moving to the fourth position, so that the first moving plate 51 can be kept in the third position, so that the first lock body is also locked in the first position, the key 4 cannot be pulled out, and the staff cannot use the key 4 to operate other chassis vehicles. In the process of the first moving assembly 12 moving from the working position to the test position, pressure will be applied to the first reset member 53, the first reset member 53 stores energy, and then applies a reset force to the first push member. In the process of the first moving assembly 12 moving from the working position to the test position, it will eventually push the first push member to move in the opposite direction of the third direction, so that the middle 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 push member, which has a simple structure and is convenient and fast. The first reset member 53 can be a spring.

[0092] Optionally, the first push member further includes a first body 523 and a first column 524. The first body 523 is connected to the middle portion 522 and is hollow. The first column 524 is disposed in the first body 523 and the first column 524 is fixed to the first front beam 11, and the first reset member 53 is sleeved on the first column 524 and disposed in the first body 523. Such a structure is very simple, easy to implement, and has low cost. The first body 523, the middle portion 522 and the special-shaped portion 521 can be integrally formed, and the three can also be integrally formed with the first column 524.

[0093] Optionally, the first front beam 11 includes a first handle operating plate 111, the first handle operating plate 111 has a first operating hole 1111, the first handle operating plate 111 can move in the third direction so that the handle can operate the first screw rod 13 to rotate, and the first moving plate 51 blocks the handle operating plate from moving in the third direction so that the first moving assembly 12 is locked in the test position. Figure 1 and Figure 2 As shown in FIG. 1 , it is a schematic diagram of the structure in which the first moving plate 51 is located on the moving path of the first handle operating plate 111. Figure 3 and Figure 4 , which is a schematic diagram of the structure in which the first movable plate 51 does not block the first handle operating plate 111. The first movable assembly 12 is locked in the test position by the first movable plate 51 blocking the movement of the handle operating plate, which has a simple structure and high reliability.

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

[0095] Wherein, when the second lock body rotates, the second movable plate 61 can move between the seventh position and the eighth position, the second movable plate 61 has a second waist hole, and the second waist hole includes a third hole 611 and a fourth hole 612 that are interconnected. When the second movable plate 61 is located at the seventh position, the second movable plate 61 can hinder the rotation of the second screw rod 23, and in the second direction, the height of the third hole 611 is less than the height of the fourth hole 612. When the second movable plate 61 is located at the eighth position, the second screw rod 23 can rotate, thereby driving the second movable assembly 22 to move between the working position and the test position. One end of the second movable plate 61 is fixed to the second lock body, specifically to the pin 31 of the second lock body. In this way, the rotation of the lock core 32 in the second lock body can drive the second movable plate 61 to move.

[0096] The shaft rod here has a rod body 621 and an annular protrusion 622 located on the rod body 621. The first end of the rod body 621 can move in the third hole 611 and the fourth hole 612. The second end of the rod body 621 can be inserted into the second movable component 22. The outer diameter of the annular protrusion 622 is larger than the height of the third hole 611 and smaller than the height of the fourth hole 612. The rod body 621 and the annular protrusion 622 can be integrally formed. When the second movable plate 61 is in the seventh position, the rod body 621 is located in the third hole 611. When the second movable plate 61 is in the eighth position and the second chassis vehicle leaves the working position, the annular protrusion 622 is located in the fourth hole 612 to prevent the second movable plate 61 from moving to the seventh position. Figure 5 and Figure 6 As shown, the cross section of the rod body 621 can be circular, and its diameter is smaller than the third hole 611 and the fourth hole 612, and the rod body 621 can move in the third hole 611 and the fourth hole 612. The outer diameter of the annular protrusion 622 is larger than the third hole 611 and smaller than the fourth hole 612, so that the annular protrusion 622 can only move in the fourth hole 612. When the annular protrusion 622 is located in the fourth hole 612, the second movable plate 61 cannot move from the eighth position to the seventh position. In this way, the second lock body remains in the sixth position, and the key 4 cannot be pulled out, and then the staff cannot use the key 4 to operate the first chassis vehicle. 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 also includes a second reset member, which is used to make the annular protrusion 622 located in the fourth hole 612 to block the second movable plate 61 from moving to the seventh position when the second movable assembly 22 leaves the working position. When the second movable assembly 22 leaves the working position, due to the action of the second reset member, the shaft rod will move along the third direction, thereby making the annular protrusion 622 located in the fourth hole 612. In this way, the second movable plate 61 cannot move to the seventh position, and then the second lock body cannot rotate to the fifth position. In this way, the key 4 cannot be pulled out, and the staff cannot use the key 4 to operate other chassis vehicles. The second reset member is used to realize the automatic reset of the shaft rod, which has a simple structure and is convenient and fast. The second reset member can specifically be a spring.

[0098] Optionally, the second interlocking assembly includes a first stopper 64 and a second stopper 65. The second reset member is sleeved on the rod body 621 and is located between the first stopper 64 and the annular protrusion 622; the second stopper 65 is fixed to one end of the rod body 621 away from the annular protrusion 622, and the rod body 621 is movably passed through the second stopper 65. When the second moving assembly 22 moves to the working position, the second moving assembly 22 can contact the second stopper 65 to drive the rod body 621 to move along the third direction, thereby causing the annular protrusion 622 to leave the fourth hole 612. As an example, Figures 5 to 7 The first stopper 64 is an L-shaped plate, and the first stopper 64 is fixed to the second front beam. When the second moving assembly 22 is in the working position, the second moving assembly 22 will pull the second stopper 65 so that the shaft rod is located in the second waist hole, such as Figure 5 and Figure 6 As shown, the second movable plate 61 can move from the seventh position to the eighth position, thereby enabling the second movable assembly 22 to move. When the second movable assembly 22 leaves the working position, the second movable assembly 22 no longer applies a force to the shaft rod through the second stopper 65. Due to the action of the second reset member, the shaft rod is pushed to move in the opposite direction of the third direction, thereby enabling the annular protrusion 622 to be located in the fourth hole 612. In the process of the second movable assembly 22 returning from the test position to the working position, the second movable assembly 22 pulls the second stopper 65 to enable the shaft rod to move as a whole along the third direction, thereby enabling the annular protrusion 622 to leave the fourth hole 612, and the rod body 621 is placed in the fourth hole 612, thereby enabling the second movable plate 61 to move from the eighth position to the seventh position.

[0099] Optionally, the second front beam includes a second handle operating plate 211, the second handle operating plate 211 has a second operating hole 2111, the second handle operating plate 211 can move in the third direction so that the handle can operate the second screw rod 23 to rotate, and the second movable plate 61 blocks the second handle operating plate 211 from moving in the third direction so that the second movable assembly 22 is locked in the working position. The second handle operating plate 211 moves along the third direction, so that the handle can be fixed on the second screw rod 23, and the staff can drive the second screw rod 23 to rotate by operating the handle to rotate, 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 has high reliability.

[0100] Optionally, the second locking mechanism further includes a limiter 66 , which is fixed to the rod body 621 to limit the moving distance of the shaft rod, 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 whole 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, and the specific reset method is, for example, to set a corresponding reset member, 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 It has been shown that the structures of the first movable plate 51 and the second movable plate 61 are the same. By adopting a common structure, the management of parts can be simplified.

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

[0104] Assume that Figure 1 and Figure 2 As shown, the first lock body is located in the first position, the first movable plate 51 is located 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 vehicle cannot be inserted and fixed to allow the first screw rod 13 to rotate, so that the first chassis vehicle is locked in the test position. At this time, the first movable assembly 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, the second lock body is located in the fifth position, and the second movable plate 61 is located in the seventh position. The second movable plate 61 blocks the second handle operating plate 211 from moving in the third direction, so that the handle of the second chassis vehicle cannot be inserted and fixed to allow the second screw 23 to rotate, so that the second chassis vehicle is locked in the working position. 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 chassis vehicle.

[0106] Assume that the first locking mechanism is currently operated. The staff inserts the key 4 into the lock core of the first lock body, and rotates the first lock body from the first position to the second position. During the rotation process, the lock core of the first lock body drives the first movable plate 51 to move from the third position to the fourth position. Under the relative movement, the middle part 522 of the first push member gradually moves from the first hole 511 to the second hole 512. The first movable plate 51 can no longer prevent the first handle operating plate 111 from moving along the third direction. Therefore, the handle of the first chassis vehicle can be inserted into the first operating hole 1111 and drive the first screw 13 to rotate. The first movable assembly 12 starts to move from the test position to the working position. The first movable assembly 12 is away from the first body 523. The first body 523 moves along the third direction under the action of the first reset member 53, so that the special-shaped portion 521 is located in the second hole 512. At this time, the first movable 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. Figure 3 and Figure 4 shown.

[0107] The staff needs to operate the second chassis vehicle, and at this time, the first chassis vehicle needs to be restored to the test position in order to pull out the key 4. The staff turns the handle of the first chassis vehicle to move the first movable assembly 12 from the working position to the test position. During the movement, the first movable assembly 12 gradually approaches the first body 523 and applies a thrust opposite to the third direction to the first body 523, so that the first body 523 moves in the opposite direction of the third direction, and then the special-shaped portion 521 leaves the second hole 512, and the middle portion 522 enters the second hole 512, so that the first movable plate 51 can move from the fourth position to the third position. At this time, the staff can turn the lock core of the first lock body so that the first lock body is restored from the second position to the first position, and the staff pulls out the key 4.

[0108] Next, the staff can insert the key 4 into the lock core of the second lock body and rotate the second lock body from the fifth position to the sixth position. The lock core of the second lock body drives the second movable plate 61 to move from the seventh position to the eighth position, and the second movable plate 61 moves relative to the shaft rod. 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. The staff can fix the handle of the second chassis vehicle with the second screw 23, and then rotate the second screw 23, so that the second movable assembly 22 moves from the working position to the test position. Figure 7 As shown. The second moving assembly 22 gradually leaves the working position, and the force applied to the second stopper 65 gradually decreases. Under the action of the second reset member, the shaft rod moves in the opposite direction of the third direction, so that the annular protrusion 622 enters the fourth hole 612. At this time, the second moving plate 61 cannot move, and it remains in the eighth position. After the second chassis vehicle 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 stopper 65, so that the shaft rod moves in the third direction, and then the annular protrusion 622 leaves the fourth hole 612, and the first end of the rod body 621 re-enters the fourth hole 612, and the second moving plate 61 can move to the seventh position. In addition, the second reset member also re-accumulates force. The staff can rotate the second lock body to rotate it from the fourth position to the third position, and the key 4 can be pulled out.

[0109] The present invention further provides a chassis vehicle assembly for a switch cabinet, which comprises any of the above-mentioned interlocking mechanisms of the chassis vehicle for a switch cabinet, a first chassis vehicle and a second chassis vehicle.

[0110] The present invention also provides a switch cabinet assembly, the switch cabinet assembly comprising a first switch cabinet and a second switch cabinet, the first switch cabinet being provided with any of the first chassis and the first locking mechanism, and the second switch cabinet being provided with any of the second chassis and the second locking mechanism. Here, both the first switch cabinet and the second switch cabinet may be air-insulated switch cabinets.

[0111] The present invention only provides an example of two chassis vehicles. In fact, there may be more chassis vehicles, such as three chassis vehicles, four chassis vehicles or even more chassis vehicles, all of which can be operated by a key 4, so that the chassis vehicles can be locked in the corresponding positions to ensure the operation sequence.
