Description

Switch cabinet

Technical Field

The utility model relates to a switch cabinet.

Background

The existing floor type switch equipment does not have an interlocking design between the door panel and the grounding switch, and the interlocking design between the grounding switch and the door panel of the existing middle-set type switch equipment has the following problems: in an interlocking scheme, an interlocking rod/sheet extends out of a cabinet and then is unlocked by a door plate when the door is closed, so that the interlocking device can be pushed by hand in actual operation and cannot be unlocked by closing the door plate strictly; in another interlocking scheme, the grounding switch operating handle can be inserted into the operating hole but cannot rotate when the interlocking mechanism is locked, and the interlocking mode can cause misoperation if not professional personnel, so that the interlocking mechanism is damaged by forced operation. The two interlocking schemes also cannot ensure that the door plate is closed when the grounding switch can be operated.

Furthermore, the known locking solutions do not take into account the situation in which the door leaf is closed but the door lock is not locked, or in which the door leaf is not closed but the door lock is locked, in both situations the locking or blocking of the access opening should be ensured.

Therefore, there is a need for a lock assembly that can ensure that the ground switch operating handle can be inserted into the operating hole for opening and closing operation when the door panel is closed in place and the door lock is rotated to the locked state with a simple and compact structure.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", "inner", "outer", and the like indicate orientations or positional relationships based on those shown in the drawings, or orientations or positional relationships that are conventionally placed when the disclosed products are used, or orientations or positional relationships that are conventionally understood by those skilled in the art, and are used merely for convenience of describing and simplifying the present disclosure, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present disclosure.

As shown in fig. 1a, 1b, 4 and 5, according to an embodiment of the present invention, the proposed switch cabinet 10 may comprise at least one door panel 100, for example comprising a front door panel and a rear door panel (not shown) arranged oppositely, and each door panel 100 is movable between an open state and a closed state. The switchgear cabinet 10 also comprises at least one locking module, each of which is coupled to a door panel 100. For each of the door panels, the associated interlocking component can be coupled to the door panel on the basis of the same construction and principle, so that the various embodiments of the switchgear cabinet comprising such an interlocking component will first be described below with respect to one of the door panels.

As shown in fig. 1a-7, the switchgear panel 10 may comprise a fixed mounting plate 200, i.e. the mounting plate 200 is fixedly arranged with respect to the switchgear panel 10, which mounting plate 200 is particularly useful for mounting and holding the various constituent components comprised by the interlocking assembly. As shown in fig. 1a, 1b, 3-4 and 6-7, the mounting plate may be secured to a side panel 700 of the switchgear panel 10 via its mounting portion 210. Of course, the mounting plate 200 may also be an integral part of the cabinet body (such as a side panel) of the switchgear cabinet 10. To achieve the interlocking between the door panels 100 and the corresponding interlocking components, the door panels 100 may be provided with a driving member 110, as shown more clearly in fig. 5, the driving member 110 may be in the form of a tab provided on the door panel 100. Thus, when the door panel 100 moves from the open state to the closed state or from the closed state to the open state, the door panel 100 may drive or release the relevant components of the interlocking assembly by the driving member 110 provided thereon.

More specifically, as shown in fig. 1a-4 and 6-7, the respective interlocking assembly may include a linkage plate 300 or 300b, an interlocking plate 400 or 400b, and a resilient return member 500 or 500 b. It should be noted that the parts of the corresponding interlocking assembly for non-door panels are distinguished by the addition of a reference numeral conforming to "b", for example, in the figures, an interlocking assembly comprising the interlocking plate 300, the interlocking plate 400 and the elastic return member 500 is used for one door panel, and another interlocking assembly comprising the interlocking plates 300b, 400b and the elastic return member 500b is used for another door panel, and the following description will be made with the interlocking assembly comprising the interlocking plate 300, the interlocking plate 400 and the elastic return member 500, but it should be understood that it applies equally to another interlocking assembly comprising the interlocking plates 300b, 400b and the elastic return member 500 b. The linkage plate 300 is movably disposed on the mounting plate 200, and is provided with a driven portion 310 that cooperates with a driving member 110 disposed on the door panel 100, and is also provided with a driving feature 320. The interlocking plate 400 is provided with a driven feature 420 for cooperating with the driving feature 320 on the linkage plate 300 to be driven by the linkage plate 300 via cooperation of the driven feature 420 with the driving feature 320 of the linkage plate 300 to move when the linkage plate 300 moves. The elastic return member 500 is connected between the mounting plate 200 and the linkage plate 300, and may take the form of a tension spring, for example, and the elastic return member 500 may store energy and release energy as needed, for example, storing energy when the door panel moves from the open state to the closed state and releasing energy when the door panel moves from the closed state to the open state.

Thus, in a switchgear panel 10 having such a door panel 100, mounting plate 200 and interlock assembly, as the door panel 100 moves from an open state to a closed state, the driving member 110 on the door panel 100 may contact the driven portion 310 on the linkage plate 300 and apply a driving force to the driven portion 310 and thus to the interlock plate 300 to drive the linkage plate 300 to move relative to the mounting plate 200 from a first position (as shown in fig. 6) to a second position (as shown in fig. 7), during which the resilient return member 500 connected between the mounting plate 200 and the linkage plate 300 may store energy and the driving feature 320 of the linkage plate 300 engages the driven feature 420 of the interlock plate 400 and thereby move the interlock plate 400 to transition the interlock plate 400 from the first state to the second state; as door panel 100 moves from the closed state to the open state, drive member 110 on door panel 100 will move away from driven portion 310 of linkage plate 300 such that door panel 100 will no longer exert a driving force on linkage plate 300, at which point resilient return member 500 will release energy that returns linkage plate 300 from the second position to the first position, during which driving feature 320 of linkage plate 300 still engages driven feature 420 of interlocking plate 400 and thereby moves interlocking plate 400 to return interlocking plate 400 from the second state to the first state. Therefore, the switch cabinet 10 of the present invention can realize the linkage between the door panel 100 and the interlocking component with a simple structure in a compact manner without occupying an additional space.

In one or some embodiments, as shown in fig. 1a-7, the switch cabinet 100 is provided with a ground operation hole 600, and the interlocking plate 400 is further provided with a blocking portion 410, so that: when the door panel 100 is in the open state, the blocking portion 410 blocks the ground operating hole 600; and when the door panel 100 is in the closed state, the blocking portion 410 no longer blocks the ground access hole 600. That is, when the door panel 100 moves from the open state to the closed state, the driving member 110 on the door panel 100 applies a driving force to the linkage plate 300 through the driven portion 310 on the linkage plate 300 to drive the linkage plate 300 to move relative to the mounting plate 200 from a first position (shown in fig. 6) to a second position (shown in fig. 7), in the process, the elastic reset member 500 connected between the mounting plate 200 and the linkage plate 300 stores energy, and the driving feature 320 of the linkage plate 300 cooperates with the driven feature 420 of the interlocking plate 400 to move the interlocking plate 400 and thus the blocking portion 410 thereof from the first state to the second state, in the first state, the blocking portion 410 of the interlocking plate 400 blocks the ground operation hole 600, and in the second state, the blocking portion 410 of the interlocking plate 400 leaves the ground operation hole 600, i.e., does not block the ground operation hole 600 any more; as door panel 100 moves from the closed state to the open state, resilient return member 500 releases energy to return linkage plate 300 from the second position to the first position, during which driving feature 320 of linkage plate 300 still engages driven feature 420 of interlocking plate 400 and thereby moves interlocking plate 400 to return interlocking plate 400, and thus its blocking portion 420, from the second state to the first state. Therefore, the present invention can realize the interlocking between the door panel 100 and the ground operation hole 600 with a simple structure in a compact manner without occupying an additional space.

In one or some embodiments, as particularly shown in fig. 6-7, the driving feature 320 on linkage plate 300 can be a pin protruding relative to the main body 330 of linkage plate 300, and the driven feature 420 on interlock plate 400 can be a slot into which the pin is inserted. More specifically, the main direction of extension of the slot is angled to the direction of movement of the linkage plate 300. For example, the slot may be arranged with its main direction of extension inclined with respect to the direction of movement of the linkage plate 300. In this way, movement of the linkage plate 300 in its direction of movement will cause movement of the interlocking plate 400 in a direction different from the direction of movement of the linkage plate through the cooperation of the pins and slots. Alternatively, in an embodiment not shown, the driving feature on the linkage plate 300 may be a slot provided in its body 330 and the driven feature on the interlock plate 400 may be an outgoing pin that goes out of the slot. More specifically, the main direction of extension of the slot is angled, for example inclined, with respect to the direction of movement of the linkage plate 300.

In one or some embodiments, as shown in fig. 6-7 in particular, mounting plate 200 is provided with at least one first guide 240, e.g., two first guides 240 as shown, and linkage plate 300 is provided with at least one first corresponding guide 340, e.g., two first corresponding guides 340 as shown, each first guide 240 cooperating with a respective first corresponding guide 340 to guide the movement of linkage plate 300 relative to mounting plate 200. More specifically, the first guide feature 240 can be a post that protrudes relative to the main plate 230 of the mounting plate 200, and the first corresponding guide 340 can be a groove disposed in the body of the linkage plate 300. Alternatively, in an embodiment not shown, the first guide feature may be a groove provided in the main plate of the mounting plate and the first corresponding guide is then a post projecting relative to the main body of the ganging plate.

In one or some embodiments, as particularly shown in fig. 6-7, mounting plate 200 is provided with at least one second guide 250, e.g., two second guides 250 as shown, and interlock plate 400 is provided with at least one second corresponding guide 450, e.g., two second corresponding guides 450 as shown, each second guide 250 cooperating with a corresponding second corresponding guide 450 to guide the movement of interlock plate 400. More specifically, the second guide portion 250 may be a post protruding with respect to the main plate 230 of the mounting plate 200, and the second corresponding guide portion 450 may be a groove provided in the interlock plate 400. Alternatively, in an embodiment not shown, the second guide portion may be a groove provided in the main plate 230 of the mounting plate 200, and the second corresponding guide portion is a post protruding with respect to the interlocking plate.

More specifically, in the switch cabinet 10 of the present invention, the movement direction of the linkage plate 300 can be perpendicular to the movement direction of the interlocking plate 400. For example, the interlocking plate 200 may be moved in translation in the horizontal direction and the interlocking plate 400 may be moved in translation in the vertical direction, such that the blocking portion 410 of the interlocking plate 400 may block the ground operating hole 600 in the lowermost position and no longer block the ground operating hole 600 in the uppermost position.

More specifically, in such an embodiment, referring to fig. 1-7, where the driving feature 320 on the linkage plate 300 is a pin and the driven feature 420 on the interlocking plate 400 is a slot, when the door panel 100 moves from the open state to the closed state, the linkage plate 300 moves relative to the mounting plate 200 from the first position shown in fig. 6 to the second position shown in fig. 7 under the driving action of the driving member 110 of the door panel 100 and under the cooperative guidance of the first guide 240 and the first corresponding guide 340, during which the pin on the linkage plate 300 as the driving feature 320 will apply a driving force to the first sidewall 421 on the interlocking plate 400 as the slot of the driven feature 420, thereby urging the interlocking plate 400 to move under the cooperative guidance of the second guide 250 and the second corresponding guide 450, upward in the embodiment shown in the figures, which will cause the blocking portion 410 of the interlocking plate 400 to move away from the ground-engaging operation aperture 600, and in the process the elastic return member 500 connected between the mounting plate 200 and the linkage plate 300 stores elastic potential energy. And when the door panel 100 moves from the closed state to the open state, the driving member 110 of the door panel 100 moves away from the driven portion 310 of the interlocking plate 300 and thus cannot apply any driving force to the interlocking plate 300 any more, the elastic restoring member 500 connected between the mounting plate 200 and the interlocking plate 300 may release the stored elastic potential energy to urge the interlocking plate 300 to restore from the second position shown in fig. 7 toward the first position shown in fig. 6 guided by the engagement of the first guide portion 240 and the first corresponding guide portion 340, during which the pin as the driving feature 320 on the interlocking plate 300 will apply a driving force to the second side wall 422 opposite to the first side wall 421 of the slot as the driven feature 420 on the interlocking plate 400, thereby urging the interlocking plate 400 to move, in the embodiment shown in the drawing, downward, this will cause the blocking portion 410 of the interlock plate 400 to block the ground operation hole 600. It should be noted that, in this embodiment, the extended length of the slot on the interlocking plate 400, the length of each guide portion should be set to allow the interlocking plate 400 to be switched between the first state of blocking the ground operation hole 600 and the second state of not blocking the ground operation hole 600, and to allow the interlocking plate 400 to be effectively stopped when the slot ends.

It should be noted that the above principles apply equally to the case where the driving feature on linkage plate 300 is a slot and the driven feature on interlocking plate 400 is a pin, when the opposing first and second sidewalls of the slot each exert a driving force on the pin in the respective states of motion.

It should also be noted that the directions of movement described herein are merely illustrative, not exclusive, and the mounting orientation and relative positions of the various components and the directions of movement therebetween may be flexibly set according to practical application constraints and requirements.

Referring particularly to fig. 6-7, in a more specific embodiment, mounting portion 210 of mounting plate 200 may be bent with respect to its main plate 230. More specifically, the main body 330 of the interlocking plate 300 may be parallel to the main plate 230 of the mounting plate 200, and the driven portion 310 of the interlocking plate 300 may be bent with respect to the main plate 330. This further facilitates a compact design of the interlock assembly and allows the interlock assembly to be installed in a confined space inside the switchgear cabinet 10.

In one or some embodiments, as shown in fig. 5 and 8, the door panel 100 is further provided with a door lock 120 and a link 130 linked with the door lock 120, the door lock 120 has a locked state and an unlocked state, and the link 130 includes a covering portion 131, such that: when the door lock 120 is in the unlocked state, the covering portion 131 of the link 130 covers the ground operation hole 600; and when the door lock 120 is in the locked state, the covering portion 131 of the link 130 is separated from the ground operation hole 600. That is, when the door lock 120 is in the unlocked state, the covering portion 131 of the link 130 covers the ground engaging hole 600, and the ground engaging hole 600 cannot be operated, but only when the door lock 120 is in the locked state, the covering portion 131 of the link 130 is separated from the ground engaging hole 600. In a more specific embodiment, as shown in fig. 5 and 8, the link 130 is provided with an aperture portion 132 therein, and when the door lock 120 is in the locked state, the aperture portion 132 is aligned with the ground operating hole 600 and the covering portion 131 is separated from the ground operating hole 600 to allow further possible operation of the ground operating hole 600, and when the door lock 120 is in the unlocked state, the aperture portion 132 is offset from the ground operating hole 600 and the covering portion 131 covers the ground operating hole 600 to restrict further operation of the ground operating hole 600.

More specifically, as shown in fig. 5 and 9, the switch cabinet 10 is provided with a hook 710, the hook 710 is more specifically provided on a side plate 700 of the switch cabinet 10, the hook 710 is provided with a locking groove 711, and the door panel 100 is provided with a hanging pin 140 linked with the door lock 120, wherein: when the door panel 100 is in the closed state and the door lock 120 is in the locked state, the hanging pin 140 will be located in the locking groove 711 of the hanging hook 710; when the door panel 100 is in the open state and the door lock 120 is in the locked state, the hanging pin 140 abuts against the outside of the hanging hook 710, and a stop for the movement of the door panel 100 from the open state to the closed state is formed. That is, in such an embodiment, when the door panel 100 is not yet closed in place, even if the door lock 120 is placed in the locked state, since the hanging pin 140 on the door panel 100 will abut against the outside of the hanging hook 710 on the switch cabinet 10 and cannot enter the locking groove 711, further movement of the door panel 100 toward the closed state will be stopped, so that the driving member 110 on the door panel 100 cannot apply a driving force to the driven portion 310 on the interlocking plate 300, thereby ensuring that the blocking portion 410 of the interlocking plate 400 can still block the ground operating hole 600. And only if the door panel 100 is closed in place and the door lock 120 is in the locked state, both the blocking portion 410 of the interlock plate 400 and the covering portion 131 of the link 130 can be removed from the ground operating hole 600 to allow further operation of the ground operating hole 600. Such a switchgear cabinet 10 allows a double locking of the ground operation hole 600 with a simple and compact structure, improving safety.

Furthermore, as mentioned above, the switchgear panel 10 may comprise more than one door panel, for example a front door panel and a rear door panel arranged opposite to each other, and an associated interlocking assembly is provided for each door panel. In such a case, the interlocking assemblies associated with each door panel may be provided on a common mounting plate 200 (as in the case of fig. 3), and an intermediate force-transmitting component may be applied between a driving member (not shown) on one of the door panels and the linkage plate 300 of the interlocking assembly to allow the driving member to apply a driving force to the linkage plate 300. Alternatively, a separate mounting plate may be provided for the interlock assembly associated with each door panel. In either form, it is possible that the blocking portions 410, 410b of the interlocking plates 400, 400b of the interlocking assembly associated with each door panel no longer block the ground access opening only when all the door panels are in the closed state; in other words, the blocking portion 410, 410b of the interlocking plate 400, 400b of its corresponding interlocking assembly will remain blocked from the ground access opening 600 as long as one of the door panels is not in the closed state. Of course, if both door panels are not in the closed state, the blocking portions 410, 410b of the interlocking plates 400, 400b of all interlocking assemblies will block the ground operation hole 600, as schematically shown in fig. 2.

The exemplary embodiment of the switch cabinet proposed by the present invention has been described in detail with reference to the preferred embodiments, however, it will be understood by those skilled in the art that various modifications and improvements can be made to the above specific embodiments without departing from the concept of the present invention, and various combinations of the various technical features and structures proposed by the present invention can be made without departing from the scope of the present invention.

The scope of the present disclosure is not defined by the above-described embodiments but is defined by the appended claims and equivalents thereof.
