[0027] The present disclosure discloses a switch device, which includes a cabinet door, a mounting plate installed on the cabinet door, a baffle that can move along a guide rail on the mounting plate, a lock tongue connected to the baffle, and an operating knob that drives the lock tongue to move. An operating hole is provided on the cabinet door. The mounting plate is installed on the inner side of the cabinet door and is located at the operating hole. The mounting plate has a through hole that is opposite to and penetrates the operating hole, and a guide rail extending along the length direction is formed on the mounting plate. The baffle portion is located on the side of the mounting plate away from the cabinet door and can move along the guide rail. The operating knob is located on the side of the mounting plate close to the cabinet door. The operating knob is connected to the lock tongue. When the operating knob moves, it drives the lock tongue to move. The lock tongue pushes the baffle to move linearly along the guide rail to block or open the through hole. The present disclosure drives the lock tongue to rotate and move by the operating knob, and the lock tongue then pushes the baffle to move linearly to block the through hole, thereby achieving the blocking of the operating hole.

[0028] In addition, since the rotational motion of the operating knob is converted into the linear motion of the baffle, the baffle does not need to rotate, thereby reducing the space required for the baffle in the vertical direction. Even a relatively small vertical space can cover the large operating hole.

[0029] It is to be understood that the foregoing general description and the following detailed description are exemplary only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] In order to further illustrate the principle and structure of the present disclosure, preferred embodiments of the present disclosure are now described in detail with reference to the accompanying drawings.

[0040] As mentioned above, the operation of the switch cabinet door needs to be shielded. However, the main method currently used is to directly install a swingable pendulum block above the operation hole. This method is relatively simple, but if the operation hole is relatively large, the corresponding pendulum block diameter is also relatively large. Relatively speaking, the space required for the pendulum block to swing is also relatively large, and the vertical space requirement is large.

[0041] In addition, if multiple operating holes are adjacent to each other, the pendulum blocks will interfere with each other and fail to meet the shielding requirements.

[0042] The present disclosure provides a switch device, which is provided with a mounting plate, a baffle and an operating knob. The rotation of the operating knob drives the baffle to move back and forth linearly along the guide rail on the mounting plate, so that the shielding plate moves to the position where the operating hole is located to shield the operating hole. Compared with the related art, which requires a large vertical space to cover the operating hole by swinging the pendulum block, the present disclosure converts the rotational movement of the operating knob into the linear movement of the baffle, and the baffle does not need to rotate, thereby reducing the space required for the baffle in the vertical direction, reducing the vertical space requirement, and even a relatively small vertical space can achieve shielding of a large operating hole.

[0043] If there are multiple operating holes adjacent to each other, since the present invention converts the rotational motion of the operating knob into the linear motion of the baffle, the multiple operating knobs can be set at a larger distance, and the multiple operating knobs will not interfere with each other, thus avoiding the problem of being unable to operate due to limited space.

[0044] like Figure 1 and Figure 2 As shown, the present disclosure provides a switchgear 1, which includes a cabinet 11, in which a plurality of electrical devices are installed, such as a circuit breaker, a three-position switch, a grounding switch, etc. The cabinet 1 has an openable cabinet door 111, and at least one operating hole 111a is provided on the cabinet door 111. The number of operating holes 111a is determined according to the specific requirements of the electrical devices in the cabinet 11.

[0045] like Figure 3 and Figure 4 As shown, the switch device 1 also includes a mounting plate 12 mounted on the inner side of the cabinet door 111, a baffle 13 that can move linearly along the mounting plate 12, a locking tongue 15 that drives the baffle to move, and an operating knob 14 that drives the locking tongue 15 to rotate.

[0046] The mounting plate 12 is located at the operating hole 111a and has a through hole 12a opposite to and through the operating hole 111a for the operating handle to be inserted.

[0047] In some embodiments, the through hole 12a can be coaxially arranged with the operation hole 111a, that is, the hole centerline of the through hole 12a coincides with the hole centerline of the operation hole 111a. The aperture size of the through hole 12a can be set to be slightly larger than the size of the operation hole 111a, so that when the through hole 12a is completely blocked, the operation hole 111a is also completely blocked, and when the through hole 12a is fully opened, the operation hole 111a is also fully opened.

[0048] like Figure 5 and Figure 6 As shown, a notch 12b is provided in the middle of the mounting plate 12, and the operating knob 14 is located at the notch 12b and can be rotated at the notch 12b.

[0049] The mounting plate 12 includes a main body 121 away from the cabinet door 11 and two folding parts 122 and 123 close to the cabinet door 111. The two folding parts 122 and 123 are respectively formed by folding two ends of the main body 121 along the length direction toward the same surface of the main body 121.

[0050] After the two ends of the main body 121 are folded relative to each other, since the two folded parts 122 and 123 have a certain thickness, the two folded parts 122 and 123 are formed with a guide surface 120a and 120b. The upper and lower guide surfaces 120a and 120b form a guide extending along the length direction for the baffle 13 to slide. Part of the structure of the baffle 13 (for example, the sliding sheet) is inserted between the two guide surfaces 120a and 120b and moves along the guide surfaces 120a and 120b.

[0051] A long hole 124 is formed in the middle of the main body 121 . The long hole 124 extends along the moving direction of the baffle 13 . The operating knob 14 is connected to the baffle 13 through the long hole 124 . The long hole 124 is opposite to the avoidance hole of the baffle 13 .

[0052] Through holes are provided at both ends of the main body 121 near the two short sides for cooperating with fasteners to fix the main body 121 to the inner side of the cabinet door 111 .

[0053] The folding parts 122 and 123 are folded on the main body 121 and cover the edge of the main body 121 in the length direction. The distance between the two folding parts 122 and 123 is substantially equal to the height of the slide part, so that the slide part can slide between the two folding parts 122 and 123.

[0054] Corresponding stop walls 1221, 1231 are provided at both ends of the two folding parts 122, 123, and the distance between the stop walls 1221, 1231 of the two folding parts 122, 123 is smaller than the height of the sliding part of the baffle 13, so that the sliding part of the baffle 13 can be limited to continue to move and prevent the sliding part of the baffle 13 from moving beyond the stroke.

[0055] A protruding piece 124 is disposed at one end of the mounting plate 12 where the short side is located, and a return spring connecting hole is disposed on the protruding piece 124 .

[0056] The baffle 13 is located on the side of the mounting plate 12 away from the cabinet door 111. Figure 7 and Figure 8 As shown, the baffle 13 includes a slide portion 131 and a driving portion 132. Specifically, the driving portion 132 includes a baffle body 1321, a bending piece 1322 located at one end of the baffle body 1321, a top piece 1323 located at the other end of the baffle body 1321, and a slide plate 1324 connected to the top piece 1323. The slide portion 131 and the slide plate 1324 are inserted between the two folding portions 122 and 123 and can move along the guide rail. The baffle body 1321 and the slide portion 131 have a certain height difference, so the baffle body 1321 arches outward relative to the slide portion 131. That is, part of the baffle 13 is located on the side of the mounting plate 12 away from the cabinet door 111, for example, the baffle body 1321, and part can move along the guide rail, for example, the slide portion 131 and the slide plate 1324.

[0057] The baffle body 1321 is connected to the slide part 131 through the bending piece 1322. The cross section of the baffle body 1321, the bending piece 1322 and the slide part 131 forms a "Z" shape. The slide plate 1324 and the slide part 131 are located on the same straight line and can move along the guide rail.

[0058] The thickness of the sliding sheet portion 131 and the sliding plate 1324 are both smaller than the thickness of the two folding portions 122 , 123 , ensuring that the sliding sheet portion 131 and the sliding plate 1324 can slide stably and smoothly on the guide rail surfaces of the folding portions 122 , 123 .

[0059] The bent piece 1322 is disposed opposite to the protruding piece 124 of the mounting plate 12. Figure 4 As shown, a reset spring 16 is provided between the bent piece 1322 and the protruding piece 124 of the mounting plate 12. One end of the reset spring 16 is connected to the protruding piece 124, and the other end is connected to the bent piece 1322. The reset spring 16 has a tendency to pull the baffle 13 toward the operating hole 111a (or through hole 12a), so that under normal conditions, the sliding piece 131 of the baffle 13 is in a state of blocking the operating hole 111a. When an external force is applied to the baffle 13, the baffle 13 is driven to move in a direction away from the operating hole 111a, the operating hole is opened, and the reset spring 16 is stretched. When the external force disappears, the reset spring 16 is reset, and the sliding piece 131 is pulled again toward the operating hole 111a, and the operating hole 111a is blocked again.

[0060] The top sheet 1323 includes a middle contact panel 1323a and convex panels 1323b extending from the contact panel 1323a to both ends.

[0061] The contact panel 1323a extends in a direction perpendicular to the movement of the baffle 13, increasing the area of ​​the contact panel 1323a. The area of ​​the contact panel 1323a is larger than the area of ​​the convex panel 1323b, ensuring that the contact panel 1323a can reliably contact the micro switch 17.

[0062] The micro switch 17 is arranged at one end of the short side of the baffle 13. When the baffle 13 moves away from the operation hole 111a and moves into position, the contact panel 1323a of the top sheet 1323 touches the micro switch 17, triggering the micro switch 17 to send a position signal.

[0063] One side of the contact panel 1323a extending toward the guide rail is bent to connect with the slide plate 1324, ensuring that the slide plate 1324 is located on the guide rail surface.

[0064] The convex panels 1323b at both ends of the contact panel 1323a are each provided with an expansion hole 1321b for configuring multiple travel switches. The multiple travel switches can provide signals for multiple background controls.

[0065] The sliding piece portion 131 and the sliding plate 1324 are located at two sides of the baffle body 1321 and can move along the guide rails at two sides of the notch 12 a respectively.

[0066] The baffle body 1321 is raised relative to the slide portion 131 and the slide plate 1324 in a direction away from the cabinet door 111, thereby increasing the space between the baffle body 1321 and the operating knob 14, providing sufficient rotation space for the operating knob 14, and preventing mutual interference between components. The slide portion 131 and the slide plate 1324 are located on both sides of the baffle body 1321, and the baffle body 1321 is parallel to the slide portion 131 and the slide plate 1324. The raised baffle body 1321 is more conducive to transmitting the force on the baffle body 1321 to the slide portion 131 and the slide plate 1324, so that the rotation amount of the operating knob 14 can be reduced to a certain extent.

[0067] The baffle body 1321 is provided with an elliptical hole in the middle. The elliptical hole 1325 is used to avoid the connection portion 141 of the operating knob 14. The connection portion 141 of the operating knob 14 passes through the elliptical hole 1325 and is connected to the baffle 13. The baffle 13 can avoid the connection between the operating knob 14 and the lock tongue 15 and move back and forth. The baffle body 1321 is also provided with a through hole 1326 for connecting the lock tongue 15.

[0068] like Figure 4 and Fig. 9 As shown, the locking tongue 15 is located on a side of the baffle body 1321 away from the mounting plate 12. The locking tongue 15 includes a rotating plate 151 and a welding column 152 disposed on the rotating plate 151. The welding column 152 and the rotating plate 151 are disposed perpendicular to each other.

[0069] The welding column 152 is connected to the baffle 13 by being inserted into the through hole 1326 of the baffle 13. The through hole 1326 is in an arch shape. The opening size of the through hole 1326 is slightly larger than the diameter of the welding column 152. When the rotating plate 151 is twisted, the welding column 151 is restricted within the range of the through hole 152, and after twisting in a small range, it pushes the baffle 13 to move linearly.

[0070] A connecting hole 153 is provided on the rotating plate 151 for connecting with the operating knob 14. The connecting portion 141 of the operating knob 14 is inserted into the connecting hole 153 for connection. The connecting hole 153 and the welding column 151 are staggered. For example, the welding column 152 is located at the upper left end of the rotating plate 151, and the connecting hole 153 is located at the lower middle part of the rotating plate 151. The staggered setting of the connecting hole 153 and the welding column 151 means that the center line of the connecting hole 153 and the axial center line of the welding column 151 deviate from each other, and are not in the same vertical direction or the same horizontal direction. In this way, when the baffle 13 is driven to move the same stroke, the rotation amount of the operating knob 14 can be reduced, thereby reducing the movement stroke of the welding column 151. Due to the reduction in the stroke of the welding column 151, the height of the slide portion 131 can also be reduced, which is beneficial to control the height of the overall assembly.

[0071] Since the operating knob 14 is connected to the connecting plate 151, and the connecting plate 151 is connected to the baffle 13 through the welding column 152, when the operating knob 14 rotates, the connecting portion of the connecting plate 151 and the operating knob 14 rotates in the same direction, and the portion of the connecting plate 151 provided with the welding column 152 rotates in the opposite direction (i.e., the rotation direction of the lower end portion of the rotating plate 151 is consistent with that of the operating knob 14, and the upper end portion rotates in the opposite direction to that of the operating knob 14), and the welding column 152 pushes the baffle 13 to make a linear motion. In this way, the rotational motion of the operating knob 14 is converted into a linear motion of the baffle 13 through the push of the welding column 152. The slide portion 131 of the baffle 13 horizontally blocks the through hole 12a, and then blocks the operating hole 111a.

[0072] like Figure 3 and Figure 4 As shown, the operating knob 14 is in a vertical state, the through hole 12a on the mounting plate 12 is blocked by the slide portion 131 of the baffle 13, and correspondingly, the operating hole 111a is also blocked due to the blocking of the through hole 12a.

[0073] like Fig.10 and Fig.11 As shown, the operating knob 14 rotates in the clockwise direction, driving the lock tongue 15 to twist, and the lock tongue 15 drives the baffle 13 to move away from the through hole 12a. When the slide plate 1324 of the baffle 14 contacts the stop walls 1221 and 1231 on the mounting plate 12, it stops moving, and the operating knob 14 cannot continue to rotate, and the through hole 12a is opened. At the same time, the contact panel 1323a of the top plate 1321 touches the micro switch 17, and the micro switch 17 sends an in-place signal to the control component. The in-place signal indicates that the operating hole has been opened, and the on-site operator needs to perform local operation, provide a grounding signal for manual local operation, and prohibit remote control at the same time to meet the safety of operation. Therefore, the setting of the baffle, while meeting the requirements of blocking or opening the operating hole, is also interlocked with the grounding switch through the micro switch.

[0074] The above are only preferred feasible embodiments of the present disclosure and are not intended to limit the protection scope of the present disclosure. All equivalent structural changes made using the contents of the present disclosure and the drawings are included in the protection scope of the present disclosure.
