Description

Technical Field

[0001] The present application relates to the technical field of switch devices, and in particular to a padlock structure and a switch device. Background Art

[0002] Switchgear is an essential component in electrical engineering, used to close and / or open one or more circuits, playing a key control role in circuits. As a switching device, a dual-power transfer switch is a core device that ensures power continuity for critical loads.

[0003] Some switchgear, including dual-power transfer switches, often feature a padlock mechanism. During switchgear inspection or maintenance, the padlock can lock the switchgear in the open position, preventing unauthorized personnel from accidentally closing the switch, which could result in electric shock or equipment damage. Alternatively, in critical power distribution applications, the padlock can lock the switchgear in the closed position to ensure continuous power supply. In some cases, the padlock can also lock the switchgear in manual mode.

[0004] However, the padlock structure in the prior art is complex, the padlock operation is inconvenient, and the sensory feedback effect given to the operator after the position of the padlock structure is switched is poor. Summary of the Invention

[0005] The present application provides a padlock structure and a switch device, which can simplify the structural complexity of the padlock structure, make the padlock operation more convenient, and improve the perceptual feedback effect given to the operator after the position of the padlock structure is switched.

[0006] In a first aspect, the present application provides a padlock structure for use with a switch device. The switch device includes an operating mechanism, and the padlock structure comprises a housing, a knob, and a baffle. The housing has a through-hole. The knob includes a handle portion and a connecting portion. The handle portion is exposed outside the housing, and the connecting portion is rotatably connected to the housing through the mounting hole. The baffle is located on the side of the housing facing away from the handle portion and is fixedly connected to the connecting portion.

[0007] The housing is provided with a first and second limiting portion on the side facing away from the handle, and the baffle is provided with an abutment portion. The housing is provided with a padlock slot and a stopper on the side facing the handle, and the handle is provided with a lock hole. Furthermore, the housing is provided with a first operating hole, and the baffle is provided with a blocking portion and a second operating hole.

[0008] When the knob drives the baffle to rotate in the first direction until the abutment engages with the first limiter, the lock hole abuts the padlock slot, placing the knob in the padlocked position. At this point, both the first and second operating holes are aligned with the operating slot of the operating mechanism. When the knob drives the baffle to rotate in the second direction until the abutment engages with the second limiter, the lock hole abuts the stopper, placing the knob in the unlocked position. At this point, the blocking portion is located between the first operating hole and the operating slot. The first direction is opposite to the second direction.

[0009] Through the above scheme, the padlock structure provided by the present application can lock the switch knob in the padlock position or the unlocked position only through the mutual cooperation of the housing, the knob and the baffle, thereby locking the switch device in the manual mode or the automatic mode. The padlock structure has a small number of structural parts, a simple structure, low cost, and the padlock operation is ergonomic and easy to operate. In addition, in the present application, after the abutting portion and the first limiting portion are in contact, the abutting portion is reliably limited by the first limiting portion, and after the abutting portion and the second limiting portion are in contact, the abutting portion is reliably limited by the second limiting portion. The obvious sense of limit makes the operator feel better when the knob switches between the padlock position and the unlocked position, or in other words, the operator feels better when switching the position.

[0010] In one possible design, a limiting rib is provided on the side of the housing facing away from the handle, and the limiting rib has a curved inner wall. A baffle is located on the side of the limiting rib near the curved inner wall and has a curved side wall. The first and second limiting portions are configured as two spaced-apart arcuate grooves on the curved inner wall, and the abutting portion is configured as an arcuate protrusion on the curved side wall.

[0011] With the above solution, when the abutting portion rotates along with the baffle in the first direction until it is located within the first limiting portion, the abutting portion is limited by the first limiting portion, so that the baffle no longer rotates in the first direction. When the abutting portion rotates along with the baffle in the second direction until it is located within the second limiting portion, the abutting portion is limited by the second limiting portion, so that the baffle no longer rotates in the second direction.

[0012] The arrangement of the arc-shaped groove and the arc-shaped protrusion enables the arc-shaped protrusion to smoothly enter the arc-shaped groove and smoothly come out of the arc-shaped groove when the baffle rotates relative to the shell, reducing the difficulty of matching between the abutment portion and the first limiting portion, and between the abutment portion and the second limiting portion.

[0013] In one possible design, a deformation notch is provided in the baffle near the abutment portion. When the abutment portion abuts the curved inner wall, the deformation notch contracts and deforms. When the abutment portion engages with the first stopper, or when the abutment portion engages with the second stopper, the deformation notch recovers.

[0014] With the above solution, when the abutment portion contacts the arcuate inner wall, the deformed notch shrinks and deforms. This reduces the possibility of wear between the abutment portion and the arcuate inner wall when the baffle rotates relative to the housing. As the baffle rotates relative to the housing, when the abutment portion engages with the first stopper, or when the abutment portion engages with the second stopper, the deformed notch recovers its deformation. This allows the abutment portion to contact the wall of the arcuate groove, allowing the abutment portion to remain stably contained within the arcuate groove.

[0015] In a possible design, the limiting ribs include a first limiting rib and a second limiting rib spaced apart from each other. The first limiting rib and the second limiting rib are symmetrically distributed on both sides of the rotation center of the knob, and the baffle is located between the first limiting rib and the second limiting rib.

[0016] The first limiting rib includes a first limiting surface, and the second limiting rib includes a second limiting surface. When the knob is in the padlock position, the first portion of the baffle abuts the first limiting surface, and the second portion of the baffle abuts the second limiting surface.

[0017] Through the above solution, when the knob is in the padlock position, not only does the abutting portion on the baffle cooperate with the first limiting portion on the housing, but the first portion of the baffle also abuts the first limiting surface, and the second portion of the baffle abuts the second limiting surface. This means that when the baffle is restricted from further rotation in the first direction to stabilize the knob in the padlock position, not only is the first limiting portion providing a limiting effect on the abutting portion, but the first limiting surface also provides a limiting effect on the first portion, and the second limiting surface also provides a limiting effect on the second portion.

[0018] The triple limiting effect enables the baffle to stay stably at the predetermined position and no longer rotate in the first direction, thereby ensuring the stability of the knob in the padlock position.

[0019] Furthermore, when the baffle plate rotates in the first direction, the first portion of the baffle plate abuts the first limiting surface, and the second portion of the baffle plate abuts the second limiting surface, which can also provide the operator with a clear sense of limit. This clear sense of limit further provides the operator with better sensory feedback when the knob switches between the padlock position and the unlocked position, or in other words, better position switching feedback.

[0020] In one possible design, the first limiting rib also includes a third limiting surface, and the second limiting rib also includes a fourth limiting surface. When the knob is in the non-padlocked position, the third part of the baffle abuts the third limiting surface, and the fourth part of the baffle abuts the fourth limiting surface.

[0021] Through the above solution, when the knob is in the unlocked position, not only does the abutting portion on the baffle cooperate with the second limiting portion on the housing, but the third portion of the baffle also abuts the third limiting surface, and the fourth portion of the baffle abuts the fourth limiting surface. This means that when the baffle is restricted from further rotation in the second direction to stabilize the knob in the unlocked position, not only is the second limiting portion providing a limiting effect on the abutting portion, but the third limiting surface also provides a limiting effect on the third portion, and the fourth limiting surface also provides a limiting effect on the fourth portion.

[0022] The triple limiting effect enables the baffle to stay stably at the predetermined position without continuing to rotate in the second direction, thereby ensuring the stability of the knob in the non-padlocked position.

[0023] Furthermore, during the movement of the baffle in the second direction, the third portion of the baffle abuts the third limiting surface, and the fourth portion of the baffle abuts the fourth limiting surface, providing the operator with a distinct sense of positional restraint. This distinct sense of positional restraint further enhances the operator's sensory feedback when the knob switches between the padlocked and unlocked positions, or provides a better sense of position switching feedback.

[0024] In one possible design, the number of each of the first limiting portion, the second limiting portion, and the abutting portion is two. One first limiting portion and one second limiting portion are provided on the arcuate inner wall of the first limiting rib and are configured to cooperate with one abutting portion. Another first limiting portion and another second limiting portion are provided on the arcuate inner wall of the second limiting rib and are configured to cooperate with the other abutting portion.

[0025] Through the above scheme, when the knob drives the baffle to rotate to a certain extent in the first direction, the abutment portion located on one side of the rotation center of the knob cooperates with the first limiting portion on that side, and the abutment portion located on the other side of the rotation center of the knob cooperates with the first limiting portion on that side. The two abutment portions are limited by the two first limiting portions, so that the baffle and the knob no longer continue to rotate in the first direction, and the knob is stably locked in the padlock position.

[0026] When the knob drives the baffle to rotate in the second direction to a certain extent, the abutment portion located on one side of the rotation center of the knob cooperates with the second limiting portion on that side, and the abutment portion located on the other side of the rotation center of the knob cooperates with the second limiting portion on that side. The two abutment portions are limited by the two second limiting portions, so that the baffle and the knob no longer continue to rotate in the second direction, and the knob is stably locked in the non-padlocked position.

[0027] In one possible design, the baffle is provided with a push portion. The padlock structure further includes a microswitch located in the rotation path of the push portion. When the knob is rotated to the padlock position, the abutment portion pushes against a spring of the microswitch, placing the microswitch in a first state. When the knob is rotated to the unlocked position, the abutment portion releases its push against the spring, placing the microswitch in a second state.

[0028] Alternatively, when the knob is rotated to the unlocked position, the abutment portion pushes the spring of the micro switch, placing the micro switch in the first state. When the knob is rotated to the locked position, the abutment portion releases the push against the spring, placing the micro switch in the second state.

[0029] When the knob is in the padlock position or the unlocked position, the abutment portion can push the spring of the micro switch, placing the micro switch in the first state. Similarly, when the knob is in the padlock position or the unlocked position, the abutment portion can release the push against the spring, placing the micro switch in the second state.

[0030] When the micro switch is in the on state, the micro switch can send an automatic control signal to the controller, causing the controller to enter the control state, so that the controller can control the switch device to automatically close or open. When the micro switch is in the off state, the micro switch can also send an automatic control signal to the controller, causing the controller to exit the control state. At this time, the controller cannot control the switch device to automatically close or open.

[0031] In one possible design, a first positioning structure is provided on the side of the connection portion facing the baffle, a second positioning structure is provided on the side of the baffle facing the connection portion, and the housing is provided with a strip-shaped hole. The end of one of the first and second positioning structures, configured as a positioning post, passes through the strip-shaped hole and extends into one of the first and second positioning structures, configured as a positioning slot. When the knob drives the baffle to rotate, the one of the first and second positioning structures, configured as a positioning post, moves within the strip-shaped hole.

[0032] Through the above scheme, when installing the knob and baffle, one end of the first positioning structure and the second positioning structure configured as the positioning column passes through the bar hole and extends into one of the first positioning structure and the second positioning structure configured as the positioning groove, which can provide a positioning effect for the installation of the knob and the baffle, so that the knob and the baffle can be installed in alignment, thereby improving the installation efficiency of the knob and the baffle.

[0033] When the knob drives the baffle to rotate, one of the first positioning structure and the second positioning structure configured as a positioning column moves in the strip hole, which can reduce the possibility of interference between the knob and the baffle and the shell when rotating relative to the shell.

[0034] In one possible design, when the knob is in the padlock position, the side of the padlock slot that abuts the lock hole contacts the side of the handle facing the padlock slot. And / or, when the knob is in the unlocked position, the side of the stopper that abuts the lock hole contacts the side of the handle facing the stopper.

[0035] By adopting the above solution, the side of the padlock slot that abuts the lock hole and the side of the handle that faces the padlock slot are arranged in surface contact, which ensures that the two have sufficient contact area when abutting, reduces the possibility of abutment failure between the two, and facilitates the stable locking of the knob in the padlock position. The side of the retaining member that abuts the lock hole and the side of the handle that faces the retaining member are arranged in surface contact, which ensures that the two have sufficient contact area when abutting, reduces the possibility of abutment failure between the two, and facilitates the stable locking of the knob in the unlocked position.

[0036] In a second aspect, the present application provides a switch device comprising an operating mechanism and the padlock structure of the first aspect, wherein the operating mechanism is located on a side of the baffle away from the knob. When the second operating hole is positioned opposite the first operating hole and the operating slot of the operating mechanism, the switch device is in manual mode. When the blocking portion is located between the first operating hole and the operating slot, the switch device is in automatic mode.

[0037] The beneficial effects of the switch device provided in the above-mentioned second aspect and each possible design of the above-mentioned second aspect can be referred to the beneficial effects brought about by the above-mentioned first aspect and each possible implementation method of the first aspect, and will not be repeated here.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0062] The switch device is an important component in electrical engineering. The switch device provided by this application includes the following Figure 1 The operating mechanism 100 and padlock structure 200 are shown.

[0063] like Figure 1 As shown, the operating mechanism 100 is provided with an operating slot 110. The padlock structure 200 includes a housing 210 and a baffle 220, which is rotatable relative to the housing 210. The housing 210 is provided with a first operating hole 211, and the baffle 220 is provided with a blocking portion 221 and a second operating hole 222. The operating mechanism 100 is located on the side of the baffle 220 away from the knob 230.

[0064] The operating slot 110 may be provided at one end of the rotating shaft of the operating mechanism 100 facing the baffle 220 , and the other end of the rotating shaft facing away from the baffle 220 may be connected to other driven components in the switch device.

[0065] When the baffle 220 rotates until the second operating hole 222 is aligned with the first operating hole 211 and the operating slot 110, the switch device is in manual mode. At this point, the operating slot 110 is connected to the first operating hole 211 via the second operating hole 222. The end of the manual operating rod in the switch device can pass through the first and second operating holes 211, 222, and then extend into the operating slot 110, where it engages with the operating slot 110. Subsequently, when the manual operating rod rotates, it drives the rotating shaft, which in turn drives the connected driven member to rotate, achieving manual opening or closing of the switch device.

[0066] When the baffle 220 rotates until the blocking portion 221 blocks the first operating hole 211 and the operating slot 110, the switch device is in automatic mode. At this point, the operating slot 110 is disconnected from the second operating hole 222 and the first operating hole 211, and the operating slot 110 is not exposed. The operator cannot manually rotate the shaft using the manual operating lever, thus preventing manual opening or closing of the switch device in automatic mode. In automatic mode, the switch device can be opened or closed by the controller.

[0067] The padlock structure 200 provided in the present application has a simple structure, is easy to operate, and provides good sensory feedback to the operator after the position of the padlock structure 200 is switched. Therefore, the switch device including the padlock structure 200 also has the effects that can be brought by the padlock structure 200.

[0068] In order to enable those skilled in the art to better understand the padlock structure 200 provided in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0069] The present application provides a padlock structure 200 , which can be applied to any switch device with padlock requirements.

[0070] Figure 2 This is a schematic structural diagram of a housing provided by an embodiment of the present application at a first viewing angle. Figure 3 This is a schematic diagram of the structure of a knob provided in an embodiment of the present application. Figures 1 to 3 As shown, the padlock structure 200 includes a housing 210 and a knob 230. The housing 210 is provided with a mounting hole 212. The knob 230 includes a handle portion 231 and a connecting portion 232. The handle portion 231 is exposed outside the housing 210, and the connecting portion 232 is rotatably connected to the housing 210 through the mounting hole 212.

[0071] like Figure 1 and Figure 2 As shown, a circular blind groove may be provided on one side of the housing 210 facing the handle portion 231 , and the housing 210 may also be provided with a mounting hole 212 , which may be a circular through hole, and the mounting hole 212 is connected to the circular blind groove.

[0072] like Figure 3 As shown, the knob 230 includes a handle portion 231 and a connecting portion 232. The handle portion 231 and the connecting portion 232 can be detachably connected by snapping, plugging, screwing, or other means. The handle portion 231 and the connecting portion 232 can also be integrally connected, which is not limited in this application. The connecting portion 232 can include a circular mounting plate 2321 and a connecting post 2322. The circular mounting plate 2321 and the connecting post 2322 can be detachably connected, or the circular mounting plate 2321 and the connecting post 2322 can be integrally formed.

[0073] When the knob 230 is installed in the housing 210, the circular mounting plate 2321 is positioned in the circular blind groove, and the connecting post 2322 is inserted into the mounting hole 212. Furthermore, the handle 231 is exposed outside the housing 210, allowing an operator to operate the handle 231 from outside the housing 210. The connecting post 2322 extends into the housing 210 so as to connect with the baffle 220 within the housing 210. After installation, the circular mounting plate 2321 can rotate relative to the circular blind groove, and the connecting post 2322 can rotate relative to the mounting hole 212. Thus, the knob 230 is rotationally connected to the housing 210 and can rotate relative to the housing 210.

[0074] Figure 4 This is a schematic diagram of the structure of a baffle provided in an embodiment of the present application. Figure 1 、 Figure 3 and Figure 4 As shown, the baffle 220 is located on a side of the housing 210 facing away from the handle portion 231 , and the baffle 220 is fixedly connected to the connecting portion 232 .

[0075] like Figure 3 As shown, the connecting column 2322 may be provided with a first connecting hole K1, and the baffle 220 may be provided with a second connecting hole 223 at a position opposite to the first connecting hole K1. A fastener such as a screw may pass through the second connecting hole 223 and connect with the first connecting hole K1 to achieve a fixed connection between the baffle 220 and the connecting portion 232.

[0076] The first connection hole K1 may be a blind hole or a threaded hole, and the second connection hole 223 may be a through hole or a smooth hole.

[0077] Alternatively, a third connecting hole may be provided on the baffle 220 at a position opposite the connecting post 2322. The connecting post 2322 passes through the mounting hole 212 on the housing 210 and then extends into the third connecting hole. The connecting post 2322 and the third connecting hole have an interference fit to achieve a fixed connection between the baffle 220 and the connecting portion 232.

[0078] It is understandable that the baffle 220 may also be fixedly connected to the connecting portion 232 in other ways, and this application does not limit this.

[0079] Figure 5 This is a schematic structural diagram of a housing provided in an embodiment of the present application at a second viewing angle, as shown in FIG. Figure 1 、 Figure 4 and Figure 5 As shown, a first limiting portion 213 and a second limiting portion 214 are provided on a side of the housing 210 facing away from the rotating handle 231 , and the baffle 220 is provided with an abutting portion 224 .

[0080] The first limiting portion 213 and the second limiting portion 214 are disposed on the rotation path of the abutting portion 224. When the baffle 220 rotates, the abutting portion 224 can engage with the first limiting portion 213 or the second limiting portion 214. When the abutting portion 224 engages with the first limiting portion 213 or the second limiting portion 214, the abutting portion 224 is restrained by the first limiting portion 213 or the second limiting portion 214, thereby limiting further rotation of the baffle 220 when no external force is applied to the baffle 220.

[0081] Please continue to refer to Figure 2 and Figure 3 A padlock slot 215 and a stopper 216 are further provided on one side of the housing 210 facing the handle portion 231 , and a lock hole 2311 is provided on the handle portion 231 .

[0082] like Figure 1 and Figure 2 As shown, a vertical plate 217 is provided on the side of the housing 210 facing the handle portion 231. The vertical plate 217 can be substantially perpendicular to the side of the housing 210 facing the handle portion 231. A padlock slot 215 can be provided on the vertical plate 217, and the padlock slot 215 can pass through the vertical plate 217 along the thickness direction of the vertical plate 217.

[0083] The blocking member 216 may be a flat plate structure, a columnar structure, etc., which is not limited in this application.

[0084] like Figure 1 and Figure 3 As shown, the handle portion 231 is in the shape of a thin plate. The handle portion 231 is also substantially perpendicular to the side of the housing 210 facing the handle portion 231. The locking hole 2311 on the handle portion 231 passes through the handle portion 231 along the thickness direction of the handle portion 231.

[0085] The padlock slot 215 and the lock hole 2311 can be circular, oval, rectangular, etc., and this application does not limit this.

[0086] Please continue to refer to Figure 1 、 Figure 2 and Figure 4 The housing 210 is further provided with a first operating hole 211 , and the baffle 220 is provided with a shielding portion 221 and a second operating hole 222 .

[0087] The position of the first operating hole 211 on the housing 210 is opposite to the position of the operating slot 110 in the operating mechanism 100 .

[0088] The baffle 220 is located on the side of the housing 210 facing away from the knob 231, and the operating mechanism 100 is located on the side of the baffle 220 away from the knob 230. The baffle 220 is generally plate-shaped, and the shielding portion 221 is the portion of the baffle 220 near the second operating hole 222. The shielding portion 221 is plate-shaped and can shield the operating slot 110, preventing the operating slot 110 from communicating with the first operating hole 211.

[0089] Based on the above structure, the working principle of the padlock structure 200 provided in this application is as follows: Figure 1 、 Figures 5 to 7 The knob 230 drives the baffle 220 to rotate in the first direction until the abutting portion 224 engages with the first limiting portion 213, and the lock hole 2311 abuts against the padlock slot 215, so that the knob 230 is in the padlock position. At this time, the first operating hole 211 and the second operating hole 222 are both opposite to the operating slot 110 of the operating mechanism 100.

[0090] Reference Figure 1 、 Figure 5 、 Figure 8 and Figure 9 The knob 230 drives the baffle 220 to rotate in the second direction until the contact portion 224 engages with the second limit portion 214, and the lock hole 2311 abuts against the stopper 216, placing the knob 230 in the unlocked position. At this time, the second operating hole 222 is offset from the operating slot 110, and the blocking portion 221 is blocked between the first operating hole 211 and the operating slot 110.

[0091] The first direction is opposite to the second direction. The first direction may be clockwise and the second direction may be counterclockwise. Alternatively, the first direction may be counterclockwise and the second direction may be clockwise.

[0092] Whether the first direction and the second direction are clockwise or counterclockwise depends on the relative positions of the padlock slot 215 and the blocking member 216 on the housing 210, as well as the placement orientation of the padlock structure 200. Figure 1 For example, the first direction may be clockwise and the second direction may be counterclockwise. Figure 1 The middle padlock slot 215 and the stopper 216 are exchanged in position, and the Figure 1 Taking the placement orientation of the padlock structure 200 as an example, the first direction is counterclockwise and the second direction is clockwise.

[0093] In simple terms, the knob 230 rotating in the first direction can be understood as the knob 230 rotating in a direction close to the padlock slot 215 , and the knob 230 rotating in the second direction can be understood as the knob 230 rotating in a direction close to the stopper 216 .

[0094] In the padlock structure 200 provided in the present application, the baffle 220 is fixedly connected to the connecting portion 232 of the knob 230. When the knob 230 drives the baffle 220 to rotate in a first direction until the abutting portion 224 on the baffle 220 engages with the first limiting portion 213 on the housing 210, the abutting portion 224 is limited by the first limiting portion 213, so that the baffle 220 no longer rotates in the first direction, and the knob 230 also no longer rotates in the first direction. At this time, the lock hole 2311 abuts the padlock slot 215, and the operator can lock the lock hole 2311 and the padlock slot 215 to lock the knob 230 in the padlock position, thereby locking the switch device in manual mode.

[0095] When the knob 230 is locked in the padlock position, the first operating hole 211 and the second operating hole 222 are opposite to the operating slot 110 of the operating mechanism 100. That is, the operating slot 110 is connected to the first operating hole 211 through the second operating hole 222, so that the operating slot 110 is exposed. In this case, the operator can pass the end of the manual operating rod through the first operating hole 211 and the second operating hole 222 in sequence and then mate with the operating slot 110 to manually control the switch device to open or close.

[0096] Conversely, when the knob 230 drives the baffle 220 to rotate in the second direction until the abutment portion 224 engages with the second limiting portion 214, the abutment portion 224 is limited by the second limiting portion 214, preventing the baffle 220 from continuing to rotate in the second direction, and the knob 230 from continuing to rotate in the second direction. At this time, the lock hole 2311 abuts the stopper 216, which blocks the lock hole 2311, preventing the lock from being engaged, thereby locking the knob 230 in the unlocked position and locking the switch device in the automatic mode.

[0097] When the knob 230 is locked in the unlocked position, the blocking portion 221 blocks the first operating hole 211 and the operating slot 110, preventing the operating slot 110 from communicating with the first operating hole 211 and, therefore, preventing the operating slot 110 from being exposed. In this situation, the operator cannot insert the end of the manual operating lever through the second operating hole 222, and thus cannot manually open or close the switch device using the manual operating lever. This ensures that the switch device cannot be manually opened or closed in automatic mode, reducing the risk of unauthorized personnel accidentally closing or opening the switch.

[0098] In summary, the padlock structure 200 provided in the present application can lock the switch knob 230 in the padlock position or the unlocked position simply by the interaction of the housing 210, the knob 230, and the baffle 220, thereby locking the switch device in the manual mode or the automatic mode. The padlock structure 200 has a small number of structural components, a simple structure, and is easy to operate. In addition, in the present application, after the abutting portion 224 cooperates with the first limiting portion 213, the abutting portion 224 is reliably limited by the first limiting portion 213, and after the abutting portion 224 cooperates with the second limiting portion 214, the abutting portion 224 is reliably limited by the second limiting portion 214. The obvious sense of limitation makes it possible for the operator to have better perceptual feedback when the knob 230 switches between the padlock position and the unlocked position, or in other words, to have better position switching feedback for the operator.

[0099] Please continue to refer to Figure 1 and Figure 5 The housing 210 is provided with a limiting rib on the side facing away from the handle 231. The limiting rib has an arc-shaped inner wall. The baffle 220 is located on the side of the limiting rib close to the arc-shaped inner wall and has an arc-shaped side wall.

[0100] Assuming that the side of the limiting rib facing the baffle 220 is the inner wall of the limiting rib, and the side of the limiting rib facing away from the baffle 220 is the outer wall of the limiting rib, the inner wall of the limiting rib can be an arcuate surface, and the outer wall of the limiting rib can be an arcuate surface or a flat surface.

[0101] Some examples, such as Figure 4 and Figure 5 As shown, the first limiting portion 213 and the second limiting portion 214 can be configured as two arc-shaped grooves spaced apart from each other on the arc-shaped inner wall, and the abutting portion 224 can be configured as an arc-shaped protrusion on the arc-shaped side wall.

[0102] The curvature of the arc-shaped side wall may be substantially the same as the curvature of the inner wall of the limiting rib, so as to reduce the possibility of interference between the arc-shaped side wall and the inner wall of the limiting rib when the baffle 220 rotates relative to the housing 210 .

[0103] The curvature of the arc-shaped protrusion and the curvature of the arc-shaped groove can be substantially the same, so that the arc-shaped protrusion can smoothly enter the arc-shaped groove and can smoothly come out of the arc-shaped groove. The arc-shaped protrusion can be integrally formed on the arc-shaped side wall.

[0104] The first limiting portion 213 and the second limiting portion 214 are both configured as arc-shaped grooves on the arc-shaped inner wall, and the abutting portion 224 is configured as an arc-shaped protrusion on the arc-shaped side wall. When the abutting portion 224 rotates with the baffle 220 in the first direction until it is located within the first limiting portion 213, the abutting portion 224 is restrained by the first limiting portion 213, preventing the baffle 220 from further rotating in the first direction. When the abutting portion 224 rotates with the baffle 220 in the second direction until it is located within the second limiting portion 214, the abutting portion 224 is reliably restrained by the second limiting portion 214, preventing the baffle 220 from further rotating in the second direction.

[0105] The arrangement of the arc-shaped groove and the arc-shaped protrusion enables the arc-shaped protrusion to smoothly enter the arc-shaped groove and smoothly come out of the arc-shaped groove when the baffle 220 rotates relative to the shell 210, thereby reducing the difficulty of matching between the abutment portion 224 and the first limiting portion 213, and between the abutment portion 224 and the second limiting portion 214.

[0106] In other examples, the first limiting portion 213 and the second limiting portion 214 can be configured as two arc-shaped grooves spaced apart from each other on the arc-shaped inner wall, and the abutting portion 224 can be configured as a connected arc-shaped stopper and an elastic member.

[0107] The arc-shaped stopper is close to the arc-shaped groove relative to the elastic member. A recessed portion may be provided on the arc-shaped side wall, one end of the elastic member is connected to the arc-shaped stopper, and the other end of the elastic member is connected to the recessed portion.

[0108] When the baffle 220 is not mounted on the side of the retaining rib near the curved inner wall, the elastic member is in a freely extended state, and the side of the arc stopper away from the elastic member protrudes from the curved sidewall. When the baffle 220 is mounted on the side of the retaining rib near the curved inner wall and the arc stopper abuts the curved inner wall of the retaining rib, the elastic member is compressed and stores energy. As the baffle 220 rotates relative to the housing 210, when the arc stopper enters the curved groove, the elastic member releases elastic potential energy. This elastic potential energy causes the arc stopper to abut against the groove wall of the curved groove, allowing the arc stopper to remain stably within the curved groove. As the baffle 220 continues to rotate, the area where the arc stopper abuts the curved groove moves, and the elastic member is further compressed and stores energy. This achieves the mating of the abutting portion 224 with the first retaining portion 213, and the mating of the abutting portion 224 with the second retaining portion 214.

[0109] When the abutting portion 224 is configured as an arc-shaped protrusion on the arc-shaped side wall, in some possible implementations, the abutting portion 224 can be made of an elastic material, or the entire baffle 220 including the abutting portion 224 can be made of an elastic material.

[0110] Thus, when the arc-shaped protrusion contacts the arc-shaped inner wall of the limiting rib, the arc-shaped protrusion can deform and shrink away from the arc-shaped inner wall, thereby reducing the possibility of wear between the arc-shaped protrusion and the arc-shaped inner wall when the baffle 220 rotates relative to the housing 210. As the baffle 220 rotates relative to the housing 210, when the arc-shaped protrusion enters the arc-shaped groove, the arc-shaped protrusion can recover its deformation toward the arc-shaped groove, contacting the groove wall of the arc-shaped groove, so that the arc-shaped protrusion is stably confined within the arc-shaped groove.

[0111] In some other possible implementations, no matter whether the abutting portion 224 is made of elastic material or rigid material, especially when the abutting portion 224 is made of rigid material, such as Figure 4 As shown, a deformation notch 225 may be provided at a portion of the baffle 220 close to the abutting portion 224 .

[0112] The shape of the deformation notch 225 can be a regular circle, square, etc., or an irregular shape, which is not limited in the present application, as long as it can provide a deformation space for the deformation of the baffle 220.

[0113] A deformation notch 225 is provided near the abutment portion 224 of the baffle plate 220. When the abutment portion 224 abuts the arcuate inner wall, the deformation notch 225 contracts and deforms. This reduces the possibility of wear between the abutment portion 224 and the arcuate inner wall when the baffle plate 220 rotates relative to the housing 210. As the baffle plate 220 rotates relative to the housing 210, when the abutment portion 224 engages with the first limiting portion 213 or the second limiting portion 214, the deformation notch 225 recovers its deformation. This allows the abutment portion 224 to abut against the wall of the arcuate groove, allowing the abutment portion 224 to remain stably contained within the arcuate groove.

[0114] Please continue to refer to Figures 5 to 9 In some embodiments, the number of limiting ribs can be multiple. This application only takes the example of two limiting ribs. Assuming that the two limiting ribs are named first limiting rib 218 and second limiting rib 219, the first limiting rib 218 and the second limiting rib 219 can be spaced and symmetrically distributed on both sides of the rotation center of the knob 230, and the baffle 220 is located between the first limiting rib 218 and the second limiting rib 219.

[0115] Some examples, such as Figures 4 to 7 As shown, the first limiting rib 218 includes a first limiting surface 2181, and the second limiting rib 219 includes a second limiting surface 2191. When the knob 230 is in the padlock position, the first portion 226 of the baffle 220 abuts against the first limiting surface 2181, and the second portion 227 of the baffle 220 abuts against the second limiting surface 2191.

[0116] An installation space is formed between the first limiting rib 218 and the second limiting rib 219. The middle portion of the baffle 220 is located in the installation space.

[0117] The first limiting rib 218 and the second limiting rib 219 are located between one end on the same side to form a first gap, and the first limiting rib 218 and the second limiting rib 219 are located between the other end on the same side to form a second gap. Assuming that the first limiting surface 2181 is the surface of the first limiting rib 218 close to the first gap, the second limiting surface 2191 is the surface of the second limiting rib 219 close to the second gap.

[0118] The first portion 226 of the baffle 220 is the portion of the baffle 220 located in the first interval and facing the first limiting surface 2181. The second portion 227 of the baffle 220 is the portion of the baffle 220 located in the second interval and facing the second limiting surface 2191.

[0119] Through the above arrangement, when the knob 230 is in the padlock position, not only does the abutting portion 224 on the baffle 220 cooperate with the first limiting portion 213 on the housing 210, but the first portion 226 of the baffle 220 also abuts against the first limiting surface 2181, and the second portion 227 of the baffle 220 abuts against the second limiting surface 2191. This means that when the baffle 220 is restricted from further rotation in the first direction to stabilize the knob 230 in the padlock position, not only is the first limiting portion 213 limiting the abutting portion 224, but the first limiting surface 2181 also limiting the first portion 226, and the second limiting surface 2191 also limiting the second portion 227.

[0120] The triple limiting effect enables the baffle 220 to stay stably at the predetermined position and no longer rotate in the first direction, thereby ensuring the stability of the knob 230 in the padlock position.

[0121] Furthermore, when the baffle 220 rotates in the first direction, the first portion 226 of the baffle 220 abuts the first limiting surface 2181, and the second portion 227 of the baffle 220 abuts the second limiting surface 2191, providing the operator with a clear sense of positional restraint. This clear sense of positional restraint further enhances the operator's sensory feedback when the knob 230 switches between the padlocked position and the unlocked position, or provides a better position switching feedback.

[0122] Continuing with the above two examples of limit bars, in other examples, such as Figure 4 、 Figure 5 、 Figure 8 and Figure 9As shown, the first limiting rib 218 also includes a third limiting surface 2182, and the second limiting rib 219 also includes a fourth limiting surface 2192. When the knob 230 is in the non-padlocked position, the third part of the baffle 220 abuts against the third limiting surface 2182, and the fourth part of the baffle 220 abuts against the fourth limiting surface 2192.

[0123] Based on the above description, the first limiting rib 218 and the second limiting rib 219 are located between ends on one side to form a first interval, and the first limiting rib 218 and the second limiting rib 219 are located between ends on the other side to form a second interval.

[0124] Assuming that the third limiting surface 2182 is the surface of the first limiting rib 218 close to the second interval, the fourth limiting surface 2192 is the surface of the second limiting rib 219 close to the first interval.

[0125] The third portion of the baffle 220 refers to the portion of the baffle 220 located in the second interval facing the third limiting surface 2182. The fourth portion of the baffle 220 refers to the portion of the baffle 220 located in the first interval facing the fourth limiting surface 2192.

[0126] Through the above arrangement, when the knob 230 is in the unlocked position, not only does the abutting portion 224 on the baffle 220 cooperate with the second limiting portion 214 on the housing 210, but the third portion of the baffle 220 also abuts against the third limiting surface 2182, and the fourth portion of the baffle 220 abuts against the fourth limiting surface 2192. This means that when the baffle 220 is restricted from further rotation in the second direction to stabilize the knob 230 in the unlocked position, not only is the second limiting portion 214 limiting the abutting portion 224, but the third limiting surface 2182 also limiting the third portion, and the fourth limiting surface 2192 also limiting the fourth portion.

[0127] The triple limiting effect enables the baffle 220 to stay stably at the predetermined position without further rotating in the second direction, thereby ensuring the stability of the knob 230 in the non-padlocked position.

[0128] Furthermore, during the rotation of the baffle 220 in the second direction, the third portion of the baffle 220 abuts against the third limiting surface 2182, and the fourth portion of the baffle 220 abuts against the fourth limiting surface 2192, which can also provide the operator with a clear sense of position limiting. This clear sense of position limiting further provides the operator with better sensory feedback when the knob 230 switches between the padlock position and the unlocked position, or in other words, provides better position switching feedback.

[0129] Please continue to refer to Figure 4 and Figure 5In some embodiments, the number of each of the first limiting portion 213, the second limiting portion 214, and the abutting portion 224 is two. One first limiting portion 213 and one second limiting portion 214 are disposed on the arcuate inner wall of the first limiting rib 218 and are configured to cooperate with one abutting portion 224. Another first limiting portion 213 and another second limiting portion 214 are disposed on the arcuate inner wall of the second limiting rib 219 and are configured to cooperate with another abutting portion 224.

[0130] The two abutting portions 224 may be symmetrically arranged on the baffle 220 , wherein one abutting portion 224 is located on one side of the rotation center of the knob 230 , and the other abutting portion 224 is located on the other side of the rotation center of the knob 230 .

[0131] The first limit portion 213 and the second limit portion 214 located on one side of the rotation center of the knob 230 are used to cooperate with the abutment portion 224 on this side. The first limit portion 213 and the second limit portion 214 located on the other side of the rotation center of the knob 230 are used to cooperate with the abutment portion 224 on this side.

[0132] Through the above-mentioned arrangement, when the knob 230 drives the baffle 220 to rotate in the first direction to a certain extent, the abutment portion 224 located on one side of the rotation center of the knob 230 cooperates with the first limiting portion 213 on that side, and the abutment portion 224 located on the other side of the rotation center of the knob 230 cooperates with the first limiting portion 213 on that side. The two abutment portions 224 are limited by the two first limiting portions 213, so that the baffle 220 and the knob 230 no longer continue to rotate in the first direction, and the knob 230 is stably locked in the padlock position.

[0133] When the knob 230 drives the baffle 220 to rotate in the second direction to a certain extent, the abutment 224 located on one side of the rotation center of the knob 230 cooperates with the second limiting portion 214 on that side, and the abutment 224 located on the other side of the rotation center of the knob 230 cooperates with the second limiting portion 214 on that side. The two abutment portions 224 are limited by the two second limiting portions 214, so that the baffle 220 and the knob 230 no longer continue to rotate in the second direction, and the knob 230 is stably locked in the non-padlocked position.

[0134] Please continue to refer to Figure 1 and Figure 4 In some embodiments, the baffle 220 is further provided with a resisting portion 228 . The padlock structure 200 further includes a micro switch 240 , which is located on the rotation path of the resisting portion 228 .

[0135] When the knob 230 is rotated to the padlock position, the abutting portion 224 pushes against the spring of the microswitch 240, placing the microswitch 240 in the first state. When the knob 230 is rotated to the unlocked position, the abutting portion 224 releases the push against the spring, placing the microswitch 240 in the second state. Alternatively, when the knob 230 is rotated to the unlocked position, the abutting portion 224 pushes against the spring of the microswitch 240, placing the microswitch 240 in the first state. When the knob 230 is rotated to the padlock position, the abutting portion 224 releases the push against the spring, placing the microswitch 240 in the second state.

[0136] The push portion 228 may be an extension of the aforementioned middle portion toward the micro switch 240. The micro switch 240 is located in the rotation path of the push portion 228. Therefore, when the push portion 228 rotates with the baffle 220, it can push the spring of the micro switch 240 to change the state of the micro switch 240.

[0137] The first state and the second state can be an off state or an on state. The first state and the second state are two opposite states. For example, when the first state is an off state, the second state is an on state. When the first state is an on state, the second state is an off state.

[0138] In the present application, when the knob 230 is in the padlocked position or the unlocked position, the contact portion 224 can push the spring of the micro switch 240, placing the micro switch 240 in the first state. Similarly, when the knob 230 is in the padlocked position or the unlocked position, the contact portion 224 can release the push against the spring, placing the micro switch 240 in the second state.

[0139] When the micro switch 240 is in the on state, the micro switch 240 can send an automatic control signal to the controller, causing the controller to enter the control state, so that the controller can control the switch device to automatically close or open. When the micro switch 240 is in the off state, the micro switch 240 can also send an automatic control signal to the controller, causing the controller to exit the control state. At this time, the controller cannot control the switch device to automatically close or open.

[0140] Please continue to refer to Figures 2 to 4 A first positioning structure 2323 may be further provided on the side of the connecting portion 232 facing the baffle 220, and a second positioning structure 229 may be provided on the side of the baffle 220 facing the connecting portion 232. The housing 210 is provided with a strip-shaped hole K2.

[0141] The end of the one of the first positioning structure 2323 and the second positioning structure 229 that is configured as a positioning post passes through the strip-shaped hole K2 and extends into the one of the first positioning structure 2323 and the second positioning structure 229 that is configured as a positioning slot. When the knob 230 drives the baffle 220 to rotate, the one of the first positioning structure 2323 and the second positioning structure 229 that is configured as a positioning post moves within the strip-shaped hole K2.

[0142] One of the first positioning structure 2323 and the second positioning structure 229 can be configured as a positioning post, and the other can be configured as a positioning slot. The positioning post is adapted to the positioning slot and can extend into the positioning slot.

[0143] Since the knob 230 is mounted on the side of the housing 210 facing away from the baffle 220, and the baffle 220 is mounted on the side of the housing 210 facing away from the knob 230, a through hole is required on the housing 210 for the positioning post to extend into the positioning slot. Furthermore, since the knob 230 and baffle 220 need to rotate relative to the housing 210 after being connected, and the positions of the first positioning structure 2323 and the second positioning structure 229 are both offset from the rotation center of the knob 230, the through hole provided on the housing 210 for the positioning post to pass through can be a bar-shaped hole K2 to reduce the possibility of interference between the knob 230 and baffle 220 and the housing 210 when they rotate relative to the housing 210.

[0144] By setting a first positioning structure 2323 on the side of the connecting portion 232 facing the baffle 220, and setting a second positioning structure 229 on the side of the baffle 220 facing the connecting portion 232, when installing the knob 230 and the baffle 220, one end of the first positioning structure 2323 and the second positioning structure 229 configured as a positioning column passes through the bar hole K2 and extends into one of the first positioning structure 2323 and the second positioning structure 229 configured as a positioning groove, which can provide a positioning effect for the installation of the knob 230 and the baffle 220, so that the knob 230 and the baffle 220 can be installed in alignment, thereby improving the installation efficiency of the knob 230 and the baffle 220.

[0145] When the knob 230 drives the baffle 220 to rotate, one of the first positioning structure 2323 and the second positioning structure 229 configured as a positioning column moves in the strip hole K2, which can reduce the possibility of interference between the knob 230 and the baffle 220 and the shell 210 when rotating relative to the shell 210.

[0146] It should be noted that when the knob 230 drives the baffle 220 to rotate in a first direction until the knob 230 is locked in the padlocked position, the positioning post can abut against the wall of the strip hole K2 on one side in the longitudinal direction. When the knob 230 drives the baffle 220 to rotate in a second direction until the knob 230 is locked in the unlocked position, the positioning post can abut against the wall of the strip hole K2 on the other side in the longitudinal direction. In this way, the wall of the strip hole K2 in the longitudinal direction can provide a clear sense of position for the positioning post. This clear sense of position provides the operator with better sensory feedback when the knob 230 switches between the padlocked and unlocked positions.

[0147] Please continue to refer to Figure 1 and Figure 6 When the knob 230 is in the padlock position, the side of the padlock slot 215 that is in contact with the lock hole 2311 contacts the side of the handle 231 facing the padlock slot 215. And / or, when the knob 230 is in the unlocked position, the side of the stopper 216 that is in contact with the lock hole 2311 contacts the side of the handle 231 facing the stopper 216.

[0148] Based on the aforementioned description of the padlock slot 215 being provided on the vertical plate 217 of the housing 210, the side of the padlock slot 215 intended to abut the lock hole 2311 corresponds to the side of the vertical plate 217 facing the stopper 216, and the side of the handle 231 facing the padlock slot 215 corresponds to the side of the handle 231 facing the vertical plate 217. Based on this, the side of the padlock slot 215 intended to abut the lock hole 2311 contacts the side of the handle 231 facing the padlock slot 215, which can be understood as the side of the vertical plate 217 facing the stopper 216 contacting the side of the handle 231 facing the vertical plate 217.

[0149] The side of the stop member 216 that is used to abut against the lock hole 2311 is equivalent to the side of the stop member 216 facing the vertical plate 217. Based on this, the side of the stop member 216 that is used to abut against the lock hole 2311 is in contact with the side of the handle portion 231 facing the stop member 216. It can be understood that the side of the stop member 216 facing the vertical plate 217 is in contact with the side of the handle portion 231 facing the stop member 216.
