Description

Technical Field

[0001] The utility model relates to the field of power distribution cabinets, in particular to a power distribution drawer and a power distribution cabinet which are convenient for clamping. Background Art

[0002] A copper busbar for power supply is provided in the cabinet cavity of the distribution cabinet, and multiple distribution drawers in the cavity are arranged in sequence along the vertical direction. Each distribution drawer is provided with electrical components, such as circuit breakers and current transformers. The electrical connection between the electrical components and the copper busbar is achieved through a plug-in assembly arranged on the rear side of the distribution drawer. In the traditional scheme, the distribution cabinet is provided with a number of shelves at intervals along the vertical direction, and a drawer cavity is formed between two adjacent shelves. A distribution drawer is provided in each drawer cavity. The distribution drawer needs a screw structure to cooperate and advance in the process of pushing the distribution drawer into the drawer cavity. The specific screw structure is located between the bottom plate and the shelf of the distribution drawer. The distribution drawer is moved into the drawer cavity by shaking the screw structure. When the screw structure is used, since the screw structure itself has a self-locking effect, it is difficult to move the distribution drawer out of the drawer cavity by directly acting on the distribution drawer after it is located in the drawer cavity.

[0003] The drawer cavity has different sizes according to design requirements, and the size depends on the type of distribution drawer required by the distribution cabinet, such as the Class A drawer cavity that matches the Class A distribution drawer, and the Class B drawer cavity that matches the Class B distribution drawer. Since the height dimensions of the Class A distribution drawer and the Class B distribution drawer are different, the height dimensions of the Class A drawer cavity and the Class B drawer cavity are different. The distribution drawers of the distribution cabinet are often arranged more densely. Therefore, in order to cram more distribution drawers into the cabinet, the height dimensions of the Class A drawer cavity and the Class B drawer cavity are completely matched with the Class A distribution drawer and the Class B distribution drawer. Therefore, the Class A drawer cavity may not be able to fit the Class B distribution drawer, and the Class B drawer cavity is stuffed into the Class A distribution drawer, resulting in a waste of cavity space. Therefore, the position interchange and quantity change of distribution drawers of different specifications in the distribution cabinet are restricted by the drawer cavity.

[0004] In order to achieve the interchange between distribution drawers of different specifications, it is necessary to remove the shelves in the distribution cabinet. Since the shelves are removed, the traditional screw structure cannot be used as the propulsion method of the distribution drawer, and therefore the self-locking effect of the screw structure cannot be used to fix the distribution drawer and the cabinet.

[0008] Furthermore, the blocking component is also provided with a pushing block in the radial direction along the rotation axis, and the plug-in component abuts against the pushing block in the sliding direction along the drawer body.

[0009] Furthermore, in the direction along the plug-in assembly approaching the copper busbar, the pushing block sequentially has a first pushing surface and a second pushing surface facing the bottom plate direction of the drawer body, and the first pushing surface has a first pushing first end and a first pushing second end relative to each other, and the second pushing surface has a second pushing first end and a second pushing second end; in the direction perpendicular to the bottom plate, the first pushing first end is located between the first pushing first end and the bottom plate, and the second pushing second end is located between the second pushing first end and the bottom plate.

[0010] Furthermore, in the direction along the plug-in assembly approaching the copper busbar, the first pushing first end and the second pushing second end are respectively located on both sides of the rotation axis of the blocking assembly.

[0011] Furthermore, the pushing block has a second pushing surface facing the bottom plate direction of the drawer body, and in the direction along the plug-in component close to the copper busbar, the second pushing surface has a second pushing first end and a second pushing second end; in the direction perpendicular to the bottom plate, the second pushing second end is located between the second pushing first end and the bottom plate, and a spring structure is provided between the blocking component and the drawer body so that the second pushing surface can be against the plug-in component.

[0012] Furthermore, when the plug-in component slides to cooperate with the copper busbar, the plug-in component abuts against the second pushing surface near the second pushing second end.

[0013] Furthermore, the power distribution drawer that is easy to snap on also includes a screw slide assembly, the plug-in assembly is connected to the slide member of the screw slide assembly, and the screw member of the screw slide assembly is connected to the drawer body.

[0015] Furthermore, the drawer body has two side panels, and two blocking components are arranged in the drawer body, and the side panels correspond to the blocking components one by one.

[0016] The power distribution cabinet provided by the utility model comprises a cabinet body, wherein the cabinet body is slidably matched with a drawer body as described in any one of the above items, a clamping part is provided at a corresponding position of the cabinet body, and the clamping part has a clamping surface facing the copper busbar.

[0017] Beneficial Effects

[0018] In this solution, a blocking component is arranged on the drawer body, and the blocking component is linked to the plug-in component. In this solution, the plug-in component and the drawer body are slidably matched, that is, the movement of the drawer body in this solution cannot directly control the contact between the plug-in component and the copper bar. The drawer body is close to the copper bar during the matching process with the cabinet body. After the drawer body and the cabinet body are matched in place, the plug-in component is slid in the same direction until it is plugged and matched with the copper bar. When the plug-in component moves toward the copper bar, the plug-in component drives the blocking component to rotate on the side panel of the drawer body. The blocking block is arranged on the blocking block and is spaced from the rotation axis of the blocking block. Due to the sliding direction of the plug-in component and the sliding direction of the drawer body The moving direction is parallel to the side plate and the bottom plate of the drawer body, while the rotation axis of the blocking assembly is perpendicular to the side plate, that is, parallel to the bottom plate. Therefore, when the blocking assembly rotates, the blocking block on the blocking assembly rotates accordingly, and displacement occurs in the direction perpendicular to the bottom plate. The specific displacement is related to the rotation angle of the blocking assembly and the spacing between the blocking block and the rotation axis of the blocking assembly. When the blocking block moves between the clamping part and the copper bar of the cabinet in the direction perpendicular to the bottom plate, the blocking block is constrained by the clamping part along the sliding direction of the drawer body, so that the drawer body cannot slide in the opposite direction, avoiding it from being separated from the cabinet, causing the electrical connection between the plug-in assembly and the copper bar to be disconnected. When the drawer body needs to be separated from the cabinet, it is necessary to first slide the plug-in assembly in the opposite direction, thereby causing the blocking assembly to rotate in the opposite direction, and the blocking block moves out from between the clamping part and the copper bar, and then slide the drawer body in the opposite direction to move the drawer body out of the cabinet.

DETAILED DESCRIPTION

[0024] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0025] Embodiment 1

[0026] A power distribution drawer that is easy to plug in, includes a drawer body and a plug-in assembly 1 located in the drawer body, the plug-in assembly 1 and the drawer body slidingly cooperate in the sliding direction along the drawer body; a blocking assembly 7 is provided on the side panel 3 of the drawer body, the blocking assembly 7 and the side panel 3 are rotationally cooperated, and the rotation axis of the blocking assembly 7 is perpendicular to the side panel 3, the blocking assembly 7 is provided with a blocking block 2 in the radial direction along the rotation axis, the blocking assembly 7 and the plug-in assembly 1 are linked and cooperated, when the plug-in assembly 1 moves toward the copper busbar, the blocking block 2 can be rotated to between the clamping part of the cabinet and the copper busbar in the sliding direction along the drawer body.

[0027] A copper busbar for power supply is provided in the cabinet cavity of the distribution cabinet, and multiple distribution drawers in the cavity are arranged in sequence along the vertical direction. Each distribution drawer is provided with electrical components, such as circuit breakers and current transformers. The electrical connection between the electrical components and the copper busbar is realized by a plug-in assembly 1 arranged on the rear side of the drawer body of the distribution drawer. In the traditional scheme, the distribution cabinet is provided with a number of shelves at intervals along the vertical direction, and a drawer cavity is formed between two adjacent shelves. A distribution drawer is provided in each drawer cavity. The distribution drawer needs a screw structure to cooperate and advance in the process of pushing the distribution drawer into the drawer cavity. The specific screw structure is located between the bottom plate 4 of the drawer body and the shelf. By shaking the screw structure, the distribution drawer is moved into the drawer cavity. When using the screw structure, since the screw structure itself has a self-locking effect, when the distribution drawer is located in the drawer cavity, it is difficult to move it out of the drawer cavity in the opposite direction by directly acting on the drawer body.

[0028] In order to achieve the interchange between distribution drawers of different specifications, there is a solution that does not set a shelf in the cabinet. Since the shelf is cancelled, the traditional screw structure cannot be used as the propulsion method of the distribution drawer, and therefore the self-locking effect of the screw structure cannot be used to fix the distribution drawer and the cabinet.

[0029] In this solution, a blocking component 7 is arranged on the drawer body, and the blocking component 7 is linked to the plug-in component 1. In this solution, the plug-in component 1 is slidably matched with the drawer body, that is, the movement of the drawer body in this solution cannot directly control the contact between the plug-in component 1 and the copper bar. The drawer body is close to the copper bar during the process of matching with the cabinet body. After the drawer body and the cabinet body are in place, the plug-in component 1 is slid in the same direction until it is plugged and matched with the copper bar. When the plug-in component 1 moves toward the copper bar, the plug-in component 1 drives the blocking component 7 to rotate on the side plate 3 of the drawer body. The blocking block 2 is arranged on the blocking component 7 and is spaced from the rotation axis of the blocking component 7. Due to the sliding direction of the plug-in component 1 and the sliding direction of the drawer body The blocking assembly 7 is parallel to the moving direction and parallel to the bottom plate 4 of the drawer body, and the rotation axis of the blocking assembly 7 is perpendicular to the side plate 3, that is, parallel to the bottom plate 4. Therefore, when the blocking assembly 7 rotates, the blocking block 2 on the blocking assembly 7 rotates accordingly, and displacement occurs in the direction perpendicular to the bottom plate 4. The specific displacement is related to the rotation angle of the blocking assembly 7 and the spacing between the blocking block 2 and the rotation axis of the blocking assembly 7. When the blocking block 2 moves between the clamping part and the copper bar of the cabinet along the direction perpendicular to the bottom plate 4, the blocking block 2 is constrained by the clamping part along the sliding direction of the drawer body, so that the drawer body cannot slide in the opposite direction, avoiding it from being separated from the cabinet, causing the electrical connection between the plug-in assembly 1 and the copper bar to be disconnected. When the drawer body needs to be separated from the cabinet, it is necessary to first slide the plug-in assembly 1 in the opposite direction, thereby causing the blocking assembly 7 to rotate in the opposite direction, and its blocking block 2 moves out from between the clamping part and the copper bar, and then slide the drawer body in the opposite direction to move the drawer body out of the cabinet.

[0030] Preferably, the blocking assembly 7 can be rotated to a predetermined angle. When the blocking assembly 7 is rotated to this position, the force generated by the abutment between the blocking block 2 and the clamping portion, and the line between the point of application of the force and the rotation axis of the blocking assembly 7 are parallel to the sliding direction of the drawer body.

[0031] In an optional embodiment, the blocking component 7 is further provided with a pushing block 9 in the radial direction along the rotation axis, and the plug-in component 1 abuts against the pushing block 9 in the sliding direction along the drawer body.

[0032] The linkage between the plug-in component 1 and the blocking component 7 is achieved through the pushing block 9, which converts the displacement of the plug-in component 1 along the sliding direction of the drawer body into the rotation of the blocking component 7. Specifically, the plug-in component 1 and the pushing block 9 are against each other in the sliding direction of the drawer body. Therefore, the plug-in component 1 can push the pushing block 9 to move during the sliding process. Since the blocking component 7 can only rotate relative to the drawer body, there is a radial distance between the pushing block 9 and the rotation axis of the blocking component 7. Therefore, the pushing block 9 can generate a torque to rotate the blocking component 7, so that the blocking component 7 rotates.

[0033] In an optional embodiment, in the direction along the plug-in assembly 1 approaching the copper busbar, the pushing block 9 sequentially has a first pushing surface 10 and a second pushing surface 11 facing the bottom plate 4 of the drawer body, and the first pushing surface 10 has a first pushing first end 12 and a first pushing second end 13 relative to each other, and the second pushing surface 11 has a second pushing first end 14 and a second pushing second end 8; in the direction perpendicular to the bottom plate 4, the first pushing first end 12 is located between the first pushing first end 12 and the bottom plate 4, and the second pushing second end 8 is located between the second pushing first end 14 and the bottom plate 4.

[0034] The second pushing surface 11 gradually approaches the bottom plate 4 of the drawer body along the direction in which the plug-in component 1 approaches the copper busbar, that is, the second pushing second end 8 is closer to the copper busbar than the second pushing first end 14, and the second pushing second end 8 is closer to the bottom plate 4 than the second pushing first end 14. There is an angle between the extending direction of the second pushing surface 11 and the direction in which the plug-in component 1 approaches the copper busbar. When the plug-in component 1 moves along the direction approaching the copper busbar, the corresponding part on the plug-in component 1 abuts against the second sliding surface, and relative sliding occurs. The plug-in component 1 gradually moves from the second pushing first end 14 of the second pushing surface 11 to the second pushing second end 8, that is, the plug-in component 1 gradually abuts against the part of the second pushing surface 11 close to the bottom plate 4, thereby pushing the second pushing surface 11, that is, the pushing block 9, to gradually move in the direction away from the bottom plate 4, and the pushing block 9 generates a torque on the blocking component 7 to rotate it, so that the blocking component 7 rotates.

[0035] The function of the first pushing surface 10 is to rotate the blocking component 7 in the opposite direction. When the plug-in component 1 is slid in the opposite direction, the blocking component 7 is pushed to rotate in the opposite direction by the first pushing surface 10, so that the blocking block 2 is moved out from between the clamping portion and the copper busbar. The specific first pushing surface 10 has a first pushing first end 12 and a first pushing second end 13 relative to each other. In the direction perpendicular to the bottom plate 4, the first pushing first end 12 is located between the first pushing first end 12 and the bottom plate 4, that is, the first pushing second end 13 is closer to the copper busbar than the first pushing first end 12, and the first pushing first end 12 is closer to the bottom plate 4 than the first pushing second end 13. When the plug-in component 1 moves in the direction away from the copper busbar, the corresponding part on the plug-in component 1 abuts against the first sliding surface, and relative sliding occurs. The plug-in component 1 gradually moves from the first pushing second end 13 of the first pushing surface 10 to the first pushing first end 12, that is, the plug-in component 1 gradually abuts against the part of the first pushing surface 10 close to the bottom plate 4, thereby pushing the first pushing surface 10, that is, the pushing block 9, to gradually move in the direction away from the bottom plate 4. The pushing block 9 generates a torque on the blocking component 7 to rotate it, so that the blocking component 7 rotates, and the rotation direction is opposite to the rotation direction when the plug-in component 1 is close to the copper busbar.

[0036] Preferably, the position where the plug-in component 1 abuts against the first pushing surface 10 and the position where the plug-in component 1 abuts against the second pushing surface 11 are respectively located on both sides of the rotation axis of the blocking component 7, and the points of application of the rotational torque generated by the plug-in component 1 on the blocking component 7 when it is close to the copper busbar and away from the copper busbar are respectively located on both sides of the rotation axis of the blocking component 7, and the direction of the rotational torque is away from the bottom plate 4, so that the blocking component 7 rotates in opposite directions when the plug-in component 1 is close to the copper busbar and away from the copper busbar.

[0037] In an optional embodiment, in the direction of the plug-in assembly 1 approaching the copper busbar, the first pushing first end 12 and the second pushing second end 8 are respectively located on both sides of the rotation axis of the blocking assembly 7 .

[0038] The pushing block 9 is V-shaped, and the two inner wall surfaces in the V form a first pushing surface 10 and a second pushing surface 11. The two ends of the V extend to both sides of the rotation axis of the blocking component 7, and the corresponding part of the plug-in component 1 is located in the opening of the V, so that the plug-in component 1 moves in opposite directions to the second pushing surface 11 and the first pushing surface 10 when approaching the copper busbar and moving away from the copper busbar.

[0039] The rotation axis of the blocking component 7 is located near the V-shaped opening, and the points of application of the rotational torque generated by the plug-in component 1 on the blocking component 7 when it approaches the copper busbar and moves away from the copper busbar are respectively located on the first pushing surface 10 and the second pushing surface 11 on both sides of the rotation axis of the blocking component 7, and the direction of the rotational torque is away from the bottom plate 4, so that the blocking component 7 rotates in opposite directions when the plug-in component 1 approaches the copper busbar and moves away from the copper busbar.

[0040] In an optional embodiment, when the plug-in component 1 slides to cooperate with the copper busbar, the plug-in component 1 abuts against the second pushing surface 11 near the second pushing second end 8 .

[0041] The function of the blocking component 7 is also to prevent the drawer body from moving in the opposite direction due to the reaction force of the lead screw component during the plug-in process of the plug-in component 1 and the copper bar. When the plug-in component 1 moves toward the copper bar, the driving force of the lead screw component is located on the drawer body. When the lead screw component pushes the plug-in component 1 to move toward the copper bar, it exerts a reverse force on the drawer body, especially when the plug-in component 1 contacts the copper bar, due to the large friction between the plug-in component 1 and the copper bar, the drawer body may move in the opposite direction until it is out of engagement with the cabinet. To avoid the above situation, after the drawer body in the present scheme is matched with the cabinet, the screw slide assembly 5 is rotated to make the plug-in assembly 1 close to the copper busbar and finally plugged with the copper busbar. During this process, the plug-in assembly 1 is always in contact with the second pushing surface 11. At this time, the blocking assembly 7 has been rotated to a predetermined angle, and the blocking block 2 is in contact with the clamping portion. As the plug-in assembly 1 continues to slide, the plug-in assembly 1 is always in contact with the second pushing surface 11. Therefore, when the plug-in assembly 1 continues to slide, the friction force generated by the plug-in assembly 1 and the copper busbar is relatively large. At this time, the clamping force between the blocking block 2 and the cabinet offsets the reverse movement force generated by the screw assembly on the drawer body, and the pushing force generated by the plug-in assembly 1 always in contact with the second pushing surface 11 maintains the rotation posture of the blocking assembly 7, ensuring that there is always a clamping force between the blocking block 2 and the cabinet, thereby avoiding the influence of the plug-in process between the plug-in assembly 1 and the copper busbar on the drawer body.

[0042] In an optional embodiment, the power distribution drawer further includes a screw slide assembly 5, the plug-in assembly 1 is connected to the slide member of the screw slide assembly 5, and the screw member of the screw slide assembly 5 is connected to the drawer body.

[0043] In an optional embodiment, a connecting rod 6 is provided between the plug-in assembly 1 and the blocking assembly 7, one end of the connecting rod 6 is fixedly matched with the slide member, and the other end can be abutted against the second pushing surface 11, and the connecting rod 6 is clearance-matched with the bottom plate 4 and the side plate 3.

[0044] In an optional embodiment, the drawer body has two side panels 3 , and two blocking components 7 are arranged in the drawer body, and the side panels 3 correspond to the blocking components 7 one by one.

[0045] Embodiment 2

[0046] In an optional embodiment, the pushing block has a second pushing surface toward the bottom plate of the drawer body, and in the direction along the plug-in component close to the copper bus, the second pushing surface has a second pushing first end and a second pushing second end; in the direction perpendicular to the bottom plate, the second pushing second end is located between the second pushing first end and the bottom plate, and a spring structure is provided between the blocking component and the drawer body so that the second pushing surface can be against the plug-in component.

[0047] The second pushing surface gradually approaches the bottom plate of the drawer body along the direction in which the plug-in component approaches the copper bar, that is, the second push second end is closer to the copper bar than the second push first end, and the second push second end is closer to the bottom plate than the second push first end. There is an angle between the extension direction of the second pushing surface and the direction in which the plug-in component approaches the copper bar. When the plug-in component moves along the direction approaching the copper bar, the corresponding part on the plug-in component abuts against the second sliding surface, and relative sliding occurs. The plug-in component gradually moves from the second push first end of the second pushing surface to the second push second end, that is, the plug-in component gradually abuts against the part of the second pushing surface close to the bottom plate, thereby pushing the second pushing surface, i.e., the pushing block, to gradually move in the direction away from the bottom plate, and the pushing block generates a torque on the blocking component to rotate it, causing the blocking component to rotate.

[0048] The function of the spring structure is to make the blocking component rotate in the opposite direction when the plug-in component is slid in the opposite direction, thereby retracting and resetting the blocking block. Specifically, the blocking component rotates under the action of the plug-in component to overcome the elastic force of the spring structure. When the plug-in component moves in the direction away from the copper busbar, the plug-in component gradually moves to abut against the part of the second push surface away from the bottom plate. Under the elastic force of the spring structure, the blocking component always makes the second push surface abut against the plug-in component, thereby making the blocking component rotate in the opposite direction, and finally the blocking block is reset, and the clamping connection between the blocking block and the cabinet body fails.

[0049] Embodiment 3

[0050] The utility model provides a power distribution cabinet, comprising a cabinet body, which is slidably matched with a drawer body as described above, and a clamping part is provided at a corresponding position of the cabinet body, wherein the clamping part has a clamping surface facing the copper busbar.

[0051] A clamping part is provided at the corresponding position of the cabinet, and the clamping part cooperates with the blocking component 7 as any of the above items. The cabinet of the power distribution cabinet is formed by assembling brackets, and a copper bar for power supply is provided in the chamber enclosed by the brackets. Multiple drawer bodies in the chamber are arranged in sequence along the arrangement direction, and the arrangement direction is from the upper end of the cabinet away from the ground to the lower end close to the ground. A blocking component 7 is provided in the drawer body, and the blocking component 7 is linked to the plug-in component 1. In this solution, the plug-in component 1 is slidably matched with the drawer body, and the drawer body is close to the copper bar during the process of matching with the cabinet. After the drawer body and the cabinet are matched in place, the plug-in component 1 is not matched with the copper bar. At this time, the screw member of the screw slide assembly 5 needs to be rotated, and the plug-in component 1 and the push member are both connected to the slide member of the screw slide assembly 5, and the screw member of the screw slide assembly 5 is connected to the drawer body. The screw member cooperates with the slide member to slide the plug assembly 1 to be plugged with the copper bar, and at the same time, the blocking assembly 7 slides in a direction perpendicular to the sliding direction of the drawer body, and the end of the blocking assembly 7 passes through the corresponding side plate 3 to the outside of the drawer body and is engaged with the cabinet. When the drawer body needs to be separated from the cabinet, the screw member needs to be rotated in the opposite direction first, so that the plug assembly 1 slides in the opposite direction to be separated from the copper bar, and the blocking assembly 7 is retracted, and then the drawer body is slid in the opposite direction to move the drawer body out of the cabinet.
