Description

Switch cabinet

Technical Field

The present disclosure relates to a switch cabinet, and more particularly, to a linkage mechanism for locking two sides of a door panel in a switch cabinet.

Background

The switch cabinet comprises a switch mechanism which can be switched between a grounding switch-on state and a grounding switch-off state. The switch cabinet also includes a fuse tube door panel made of metal that allows for repair or replacement of the fuse tube when the door panel is opened. In order to ensure the safety of an operator, when the switch mechanism is in a grounding opening state, the fuse tube door panel is in a closed state and cannot be opened, and only when the switch mechanism is in a grounding closing state, the fuse tube door panel is allowed to be opened.

A fuse tube door panel in the prior art has an interlocking mechanism that includes a rotating latch and a horizontally sliding latch for latching door hooks located on both sides of the door panel. Specifically, the rotary lock catch can rotate and is matched with one door hook to lock one side (for example, the right side) of the door panel, the horizontal sliding lock catch can be matched with the other door hook to lock the other side (for example, the left side) of the door panel through horizontal sliding of one wedge-shaped part, the arrangement is such that the door panel made of a metal material can deform when being pulled in an opening direction, and under the action of the door hook, the wedge-shaped part of the horizontal sliding lock catch can slide towards a loosening direction, so that a gap is formed between the left side of the door panel and a switch cabinet shell and cannot be locked, so that a conductive object (such as a conductive wire) can enter the switch cabinet from the gap to cause unnecessary electric leakage, and particulate matters (particularly particulate matters with the diameter larger than 1 mm) can enter the switch cabinet from the gap to further influence the performance of the switch cabinet. In addition, the interlocking mechanism of the fuse tube door plate in the prior art is complex in structure, multiple in transmission parts and long in size chain, so that the installation and debugging are difficult.

Therefore, those skilled in the art are dedicated to develop a switch cabinet, which has a simple structure and an interlocking mechanism that is easy to install and debug, and when the door panel is in the closed state, both sides of the door panel are locked, and no gap is generated between the door panel and the switch cabinet housing due to pulling.

Detailed Description

Embodiments of the present disclosure are described below with reference to specific embodiments, and other advantages and effects of the present disclosure will be readily apparent to those skilled in the art from the disclosure herein.

It should be understood that the structures, proportions, and dimensions shown in the drawings and described herein are for illustrative purposes only and are not intended to limit the scope of the present disclosure, which is to be given the full breadth of the present disclosure, but rather the scope of the present disclosure should not be limited by any of the above-described exemplary embodiments. In addition, the terms such as "above", "below", "left", "right" and "one" used in the present specification are used for the sake of clarity only, and are not intended to limit the scope of the present disclosure, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes.

For a more clear understanding of the present disclosure, embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 4, the switch cabinet includes a door panel 100 and an interlocking mechanism 200 for locking the door panel 100 to a switch cabinet housing. The door panel 100 has a first end (e.g., a bottom end in fig. 2) pivotally connected to the housing of the switchgear cabinet such that the door panel 100 is rotatable between an open position and a closed position, and a second end (e.g., a top end in fig. 2). The door panel 100 includes a first door hook 110 and a second door hook 120 respectively disposed at two sides of the second end of the door panel 100, and the first door hook 110 and the second door hook 120 are respectively provided with openings 111 and 121 for engaging with the interlocking mechanism 200. In one embodiment, the door panel 100 may be a fuse tube door panel, although the disclosure is not limited thereto.

Referring to fig. 3 and 4, the interlocking mechanism 200 includes a support 210, a transmission shaft 220, a first driving latch 230, a second driven latch 240, and a stopper assembly 250. The support 210 is fixedly mounted on the housing of the switchgear cabinet, in particular on a cross member of the housing. The transmission shaft 220 is pivotally connected to the support 210, so that the transmission shaft 220 can rotate relative to the housing. The driving shaft 220 is provided at both ends thereof with a first driving latch 230 and a second driven latch 240, respectively, for engaging the first door hook 110 and the second door hook 120 to latch the door panel 100.

With reference to fig. 4, the first driving latch 230 includes a first driving portion 231, a second driving portion 232, a third abutting portion 233, a fourth stopping portion 234 and a fifth mounting portion 235. The first driving portion 231 is configured to be pushed by the first door hook 110 during the closing process of the door panel 100, so that the first driving latch 230 can rotate along the first rotating direction D1. The second driving portion 232 is configured to be pushed/pulled by the first door hook 100 in the process of opening the door panel 100, so that the first driving catch 230 can rotate along a second rotation direction D2 opposite to the first rotation direction D1, and when the door panel 100 is in the closed position, the second driving portion 232 can be completely inserted into the opening 111 of the first door hook 110 and hook the first portion 1110 (as shown in fig. 2) of the opening 111, so as to avoid the problem that the door panel 100 can rotate for an angle towards the opening direction and then contact the second driving portion 232 to generate a gap between the door panel 100 and the housing. In an embodiment, the extension length of the first driving portion 231 may be greater than the extension length of the second driving portion 232, so that the first door hook 110 contacts the first driving portion 231 first during the closing process of the door panel 100, and the first door groove 110 does not contact the second driving portion 232. The third abutment 233 is for abutting the stop assembly 250. The fourth stopping portion 234 is configured to cooperate with the first limiting member 211 (as shown in fig. 3) disposed on the supporting base 210 to limit the maximum angle of the first driving latch 230 rotating along the second rotating direction D2.

In one embodiment, the interlocking mechanism 200 further includes a first elastic member S1 (shown in fig. 3 and 5), one end of which is fixed to the fifth mounting portion 235 of the first driving latch 230 and configured to bias the first driving latch 230 toward the second rotation direction D2 when the door panel 100 is in the open position (i.e., the first elastic member S1 is located obliquely above the rotation axis X1 of the first driving latch 230 when the door panel 100 is in the open position); and biases the first driving locker 230 toward the first rotating direction D1 when the door panel 100 is in the closed position (i.e., the first elastic member S1 is located obliquely below the rotation axis X1 when the door panel 100 is in the closed position) for preventing the door panel 100 from being automatically opened.

In an embodiment, the other end of the first elastic member S1 may be directly fixed to the support 210, the casing of the switch cabinet, or other components, or may be fixed to the first sliding plate 212 (as shown in fig. 3 and 13), so long as the first driving latch 230 is biased toward the second rotating direction D2 when the door panel 100 is in the open position, and the first driving latch 230 is biased toward the first rotating direction D1 when the door panel 100 is in the closed position.

The disclosure is exemplified by that the other end of the first elastic member S1 is fixed to the first sliding plate 212, wherein the first sliding plate 212 is slidably mounted on the support 210, and the first sliding plate 212 can be linked with the first driving latch 230 under the action of the first spring member S1. Specifically, in this embodiment, the first driving latch 230 further includes a sixth abutting portion 236, the first slider 212 abuts against the sixth abutting portion 236 under the action of the first elastic member S1, wherein the sixth abutting portion 236 is configured to abut against the first slider 212 to slide back and forth relative to the support 210 during the rotation of the first driving latch 230, so that the first elastic member S1 is located obliquely above the rotation axis X1 of the first driving latch 230 (i.e., the first driving latch 230 is biased toward the second rotation direction D2) when the door panel 100 is in the open position, and the first elastic member S1 is located obliquely below the rotation axis X1 (i.e., the first driving latch 230 is biased toward the first rotation direction D1) when the door panel 100 is in the closed position.

In a preferred embodiment, the interlocking mechanism 200 may further include a second elastic member S2 connected between the support 210 and the first sliding plate 212. The first and second elastic members S1 and S2 are respectively disposed at opposite sides of the first sliding plate 212 so that the first sliding plate 212 can smoothly slide reciprocally with respect to the holder 210.

With continued reference to fig. 4, the second driven latch 240 of the interlock mechanism 200 includes a first portion L1 fixed to the transmission shaft 220; a second portion L2 for insertion into the opening 121 of the second door hook 120; and a bent portion L3 connecting the first portion L1 and the second portion L2. Since the first driving latch 230 and the second driven latch 240 are fixedly disposed at both ends of the transmission shaft 220, when the first driving latch 230 rotates around the rotation axis X1, the second driven latch 240 can be driven to rotate via the transmission shaft 220, so as to simultaneously lock the first door hook 110 and the second door hook 120 or simultaneously unlock the doors.

In an embodiment, a second limiting member (not shown) may be disposed on the housing of the switch cabinet, and is used for abutting against the door panel 100 when the door panel 100 is in the closed position, so that the door panel 100 cannot rotate in the closing direction, that is, the door panel 100 can only rotate in the opening position. However, the disclosure is not limited thereto, for example, the second position-limiting portion may also be disposed on the support 210, and when the first driving latch 230 rotates along the first rotating direction D1 to abut against the second position-limiting portion, the door panel 100 is at the closed position, that is, when the door panel 100 is at the closed position, the second position-limiting portion may stop the first driving latch 230 to continue to rotate along the first rotating direction D1. For another example, the second position-limiting portion may also be disposed on the first driving latch 230, and when the first driving latch 230 rotates to the closed position corresponding to the door panel, the second position-limiting portion cooperates with the first sliding plate 212 to limit the first driving latch 230 to continue to rotate along the first rotation direction.

Referring to fig. 5-9, the positional relationship between the door panel 100 and the interlocking mechanism 200 is shown during the process of switching the door panel 100 from the open position to the closed position.

As shown in fig. 5, when the door panel 100 is at the open position, the first driving latch 230 is biased toward the second rotation direction S2 by the first elastic member S1, so that the fourth stopping portion 234 of the first driving latch 230 abuts against the first limiting member 211 to stop the first driving latch 230 from rotating toward the second rotation direction S2, that is, the first driving latch 230 is kept at the position shown in fig. 5, which enables the first door hook 110 to abut against the first driving portion 231 of the first driving latch 230 first when the door panel 100 is closed, and at this time, the first door hook 110 does not contact with the second driving portion 231.

Specifically, as shown in fig. 6-9, in the process of rotating the door panel 100 from the open position to the closed position, the first door hook 110 first contacts the first driving portion 231 (as shown in fig. 6) of the first driving latch 230 and pushes against the first driving portion 231, so that the first driving latch 230 rotates in the first rotating direction D1 until the door panel 110 is at the closed position, as shown in fig. 9, at this time, the second driving portion 232 is completely inserted into the opening 111 of the first door hook 110 (although the disclosure is not limited thereto, the second driving portion 232 may also be partially inserted into the opening 111), and one side of the second driving portion 232 facing the first driving portion 231 hooks the first portion 1110 of the opening 111. Moreover, the first driving latch 230 drives the second driven latch 220 to rotate via the transmission shaft 220 in the rotating process, so that the second portion L2 of the second driven latch 220 is completely or partially inserted into the opening 121 of the second door hook 120, and hooks the first portion 1210 of the opening 121 (as shown in fig. 2).

Referring to fig. 9, the door panel 100 is in the closed position, and the second position-limiting portion can prevent the door panel 110 from rotating in the closing direction, and the first elastic member S1 is located below the rotation axis X1, so that the first driving latch 230 has a moment rotating in the first rotation direction D1 to prevent the door panel 100 from being automatically opened, and at this time, the door panel 100 and the enclosure of the switch cabinet are tightly covered and have no gap.

To prevent the door panel 100 from being opened by the operator when the door panel 100 is in the closed position, the interlocking mechanism 200 further includes a stop assembly 250, as shown in fig. 10, the stop assembly 250 is configured to selectively stop the rotation of the first driving latch 230 when the first driving latch 230 is fully engaged with the first door hook 110 (i.e., the door panel 100 is in the closed position) to prevent the door panel 100 from being opened.

Specifically, stop assembly 250 includes a slide stop 251 and a cam 252. As shown in fig. 10 and 11, the slide stopper 251 is configured to be slidable with respect to the housing and to be held in abutment with the first drive latch 230. In an embodiment, the slide stopper 251 may include at least one third guide groove 2513 for engaging a corresponding number of guides 253 provided on the housing, and the sliding of the slide stopper 251 relative to the housing is achieved by the engagement of the two, although the present disclosure is not limited thereto as long as the slide stopper 251 can slide relative to the housing.

The slide stop 251 further includes a first abutment 2511 and a second abutment 2512. The first abutment 2511 is for abutting the third abutment 233 of the first drive catch 230. In an embodiment, the slide stop 251 may hold the first abutment 2511 against the third abutment 233 by its gravitational force. Preferably, the third elastic member S3 may be disposed between the sliding stopper 251 and the housing, and the first abutting portion 2511 is kept abutting against the third abutting portion 233 under the pulling force of the third elastic member S3, so as to avoid the technical problem that the sliding stopper 251 cannot be kept abutting against the first driving latch 230 due to the jamming between the sliding stopper 251 and the housing or other components.

The second abutment 2512 of the slide stopper 251 is for engaging the cam 252. The cam 252 may selectively abut the second abutment 2512. Specifically, the cam 252 is configured to rotate relative to the housing between a stop position and a non-stop position. When the cam 252 is in the stop position (as shown in fig. 10), the cam 252 abuts against the second abutment 2512, so that the slide stopper 251 cannot slide relative to the housing; when the cam 252 is in the non-stop position, the cam 252 is clear of the second abutment 2512, at which time the slide stop 251 can slide relative to the housing.

The switchgear cabinet furthermore comprises a switching mechanism (not shown) which can be switched between a ground-closed state and a ground-open state. To ensure safety, the door panel of the switchgear (including but not limited to the door panel 100 described above) is only allowed to be opened if the switching mechanism is in the ground-closed state; when the switch mechanism is in a grounding opening state, the door plate can not be opened. The specific structure and state switching process of the switch mechanism are well known to those skilled in the art and will not be described herein.

The cam 252 is linked to the state switching of the switch mechanism. Specifically, when the switching mechanism is in the ground-closing state, the cam 252 is in the non-stop position (as shown in fig. 12), and at this time, the door panel 100 is allowed to open; when the switch mechanism is in the ground-breaking state, the cam 252 is in the stop position (as shown in fig. 10), and the door panel 100 cannot be opened.

With reference to fig. 9 and 10, when the door panel 100 is at the closed position, the first driving latch 230 and the second driven latch 240 respectively hook the first door hook 110 and the second door hook 120, the first abutting portion 2511 of the sliding stop 251 abuts against the third abutting portion 233 of the first driving latch 230, and the sliding stop 251 is located at a dead point position (e.g., a bottom dead point position in fig. 10) in the sliding stroke, so that the door panel 100 and the housing of the switch cabinet are tightly covered and have no gap. At this time, if the door panel 100 is not desired to be opened, the opening and closing mechanism is switched to the ground opening state, so that the cam 252 is located at the stopping position (as shown in fig. 10), and even if the door panel 100 is pulled toward the opening direction, the sliding stopper 251 cannot slide upward due to the abutting of the cam 252, so that the first driving latch 230 can be prevented from rotating in the second rotating direction D2, and the door panel 100 is kept at the closing position and no gap is generated between the door panel 100 and the shell of the switch cabinet, therefore, the interlocking mechanism 200 can lock the door panel 100 on both sides, and the technical defect caused by the fact that the door panel cannot be locked on one side (for example, on the left side) in the prior art is avoided.

Referring to fig. 10 and 12, when the door panel 100 is at the closed position, if the door panel 100 is allowed to be opened, the switch mechanism is switched to the ground-closing state, so that the cam 252 is at the non-stop position (as shown in fig. 12), that is, the cam 252 is away from the second abutting portion 2512, the sliding stop 251 can slide upwards, and at this time, if the door panel 100 is pulled in the opening direction, the first door hook 110 will push/pull the second driving portion 232 of the first driving latch 230, so that the first driving latch 230 rotates in the second rotating direction D2, and the door panel 100 is opened.

In addition, the door panel 100 and the interlocking mechanism 200 according to the present disclosure are not limited to the above-described structure, and for example, the door panel 100 may further include at least one third door hook (not shown) disposed between the first door hook 110 and the second door hook 120. The interlocking mechanism 200 may further include at least one third driven locker (not shown) fixed to the transmission shaft 220 and disposed between the first driving locker 230 and the second driven locker 220, and adapted to engage with at least one third door hook to more effectively lock the door panel 100.

Also, the stopping assembly 250 of the present disclosure is not limited to the above structure, as long as the first driving latch 230 is allowed to rotate along the second rotation direction D when the switching mechanism is in the ground switching-on state, and the first driving latch 230 can be stopped from rotating along the second rotation direction D when the switching mechanism is in the ground switching-off state.

The present disclosure provides a switchgear cabinet having an interlocking mechanism that can lock both sides of a door panel without generating a gap with a case. Specifically, interlocking gear is through the fixed first drive hasp and the driven hasp of second that sets up in the both ends of transmission shaft, and first drive hasp can be followed first direction of rotation and rotatory in order to pin first door hook under the drive of the first door hook of door plant, and the rotation of first drive hasp can drive the driven hasp of second rotatory via the conveying axle simultaneously, with the second door hook can prevent that first drive hasp from following the second direction of rotation rotatory in addition through interlocking gear's backstop subassembly, namely, prevents to take off the lock. Therefore, the interlocking mechanism provided by the disclosure has a simple structure, is convenient to install and debug, can enable two sides of the door plate to be locked when the door plate is in a closed state, and cannot generate a gap between the door plate and a switch cabinet shell due to pulling.
