The utility model is described in detail below by way of description of example embodiments.
The control cabinet generally comprises a cabinet body and a cabinet door closing the cabinet body, the cabinet door being capable of being switched between an open state and a closed state to open and close the control cabinet, respectively. When the cabinet door is in an open state, maintenance personnel can access or view components provided in the control cabinet, such as the operating panel 1 and the elements thereon. When the cabinet door is in a closed state, the cabinet door and the cabinet body can seal the control cabinet so as to prevent foreign matters such as dust from entering the control cabinet. The cabinet door is rotatably mounted to the cabinet body, for example, to rotate between an open state and a closed state.
The control cabinet further comprises an operation panel 1 installed inside the control cabinet to control the operation of the apparatus. According to one embodiment of the utility model the apparatus is an elevator and the control cabinet is a control cabinet of an elevator. It will be appreciated that the utility model is not limited thereto and that the device may be other electrical devices.
The operation panel 1 is provided with an interface configured to output signals from the operation panel 1 and input signals to the operation panel 1, for example, an RS232 interface. In order to control the interface, the operation panel 1 is further provided with a switch 2 connected to the interface, the interface being capable of inputting and outputting signals when the switch 2 is in the on position, and being incapable of inputting and outputting signals when the switch 2 is in the off position. The switch 2 is, for example, a DIP switch 2. The operation panel 1 may include a plurality of DIP switches, and the DIP switch 2 of the control interface is, for example, the DIP switch 2 disposed closest to the interface. The switch 2 of the control interface will be referred to below simply as switch 2.
In maintaining the device, the user typically needs to set the switch 2 of the control interface to an open position. However, there is a possibility that the user forgets to reset the switch 2 to the on position after the maintenance is completed. In order to prevent this possible inconvenience, the control cabinet according to the utility model further comprises error proofing means configured to prevent closing of the cabinet door when the switch 2 is still in the open position. The control cabinet may include a fixing member 4 fixed to the operation panel 1 and an operation handle 3 rotatably mounted to the fixing member 4. The operating handle 3 is mounted adjacent to the switch 2 to the fixture 4 and rotatable between a permitted position and a blocking position, such that when the operating handle 3 is rotated to the blocking position, the switch 2 is actuated by the operating handle 3 to an open position, and at this point the operating handle 3 extends outside the control cabinet, thereby blocking the cabinet door from closing the control cabinet; when the operating handle 3 is rotated to the allowed position, the switch 2 is actuated to the on position by the operating handle 3 and the operating handle 3 is retracted inside the control cabinet, thereby allowing the cabinet door to close the control cabinet. The position of the switch 2 is thus linked to whether the door can be closed by operating the handle 3, so as to avoid the possibility of closing the door by forgetting to reset the switch 2 to the on position.
Specifically, as shown in fig. 5, the fixing member 4 is, for example, in the form of a frame, and may include a through hole configured to accommodate the switch 2, and a pivoting portion configured to cooperate with the operation handle 3 to allow the operation handle 3 to pivot and actuate the switch 2. As shown in fig. 1, the fixing member 4 is mounted around the switch 2 so that the pivoting portion is aligned with the switch 2.
As shown in fig. 4, according to one embodiment, the operating handle 3 may include a body 31 extending in a length direction, and a first end 32 of the body 31 is rotatably mounted to a pivoting portion of the fixed member 4 so that the operating handle 3 as a whole can be rotated with respect to the fixed member 4. The operating handle 3 may further comprise a first leg 34 and a second leg 35 extending from the first end 32 towards different directions, the length and extending direction of the first leg 34 and the second leg 35 being such that when the operating handle 3 is rotated to the blocking position, rotation of the first leg 34 actuates the switch 2 to the off position for a maintenance operation by a user, and when the operating handle 3 is rotated to the allowing position, rotation of the second leg 35 actuates the switch 2 to the on position, so that the interface can input and output signals, thereby realizing a function of avoiding forgetting to reset the switch 2 to the on position. In the embodiment of fig. 4, the first leg 34 extends parallel to the main body 31 and the second leg 35 extends perpendicular to the main body 31, however, it will be understood by those skilled in the art that the extending directions of the first leg 34 and the second leg 35 may be changed as long as the above-described functions can be satisfied. Alternatively, the body 31 and the first and second legs 34, 35 may be integrally formed.
With continued reference to fig. 4, a second end 33 of the operating handle 3, opposite the first end 32, may be provided with warning signs and/or be colored with warning colors. The warning sign and/or warning color is arranged in the direction of the user when the operating handle 3 is in the blocking position, so that the user is warned that the switch 2 is still in the off position at this time and needs to be reset. The warning mark is, for example, an exclamation mark. The warning color is, for example, yellow or red. For example, as shown in fig. 2 and 3, when the operation handle 3 is rotated to the blocking position, the main body 31 extends perpendicularly to the operation panel 1, when the operation handle 3 is rotated to the allowing position, the main body 31 extends parallel to the operation panel 1, the second end 33 of the operation handle 3 includes a grip portion bent from the main body 31 toward the user direction in the allowing position, and a warning mark and/or a warning color is provided on a surface of the grip portion as shown in fig. 4. An allow flag, e.g. an OK flag, may also be set on the face of the second end 33 of the operating handle 3 facing the direction of the user when in the allow position to indicate to the user that the switch 2 is now in the on position. For example, the permission sign is provided at a widened portion of the main body 31 near the grip portion, as shown in fig. 4.
Preferably, a certain rotation damping can exist between the operation handle 3 and the fixing piece 4, so that the position of the operation handle 3 is prevented from being changed by mistakenly touching the operation handle 3.
Preferably, the control cabinet may further include a protection plate 5 disposed above the operation panel 1 and fixed to the operation panel 1. As shown in fig. 1 to 3, the protection plate 5 is transparent, a plurality of through holes are provided so that elements provided at positions on the operation panel 1 corresponding to the plurality of through holes are accessible from the front, and the error preventing device is mounted to the operation panel 1 through the notch of the protection plate 5. In the embodiment of fig. 1, the error proofing device is mounted to the operation panel 1 at a notch in the lower right corner of the operation panel 1. The height of the protection plate 5 is set so as not to interfere with the rotation of the operation handle 3, and elements provided on the operation panel 1 can be protected.
Two positions in the installation and use of the error proofing device according to one embodiment of the present utility model are described below with reference to fig. 1-3.
Referring to fig. 1, the error preventing means is installed above the switch 2 of the operation panel 1 through a notch of the protection plate 5 such that rotation of both legs of the operation handle 3 can actuate the switch 2.
Referring to fig. 2, the operating handle 3 is in the blocking position, while the switch 2 is actuated by the operating handle 3 to the off position, allowing a user to perform a maintenance operation, when the main body 31 of the operating handle 3 extends outwardly beyond the cabinet body of the control cabinet perpendicular to the operating panel 1, blocking the cabinet door from closing the control cabinet, the second end 33 of the main body 31 being provided with a warning sign and/or being colored in a warning color towards the user, warning the user that the switch 2 is not on at this time.
Referring to fig. 3, the operating handle 3 is in the allowed position, while the switch 2 is actuated by the operating handle 3 to the on position, allowing the interface to input and output signals, at which time the body 31 of the operating handle 3 extends parallel to the operating panel 1, allowing the cabinet door to close the control cabinet, the second end 33 of the body 31 being provided with an allowing flag in the direction of the user, indicating to the user that the switch 2 is on at this time.
