[0022] In order to better understand the technical content of the present utility model, specific embodiments are hereby given and described in conjunction with the accompanying drawings as follows.
[0023] AsFigure 1 As shown in the figure, the utility model provides a double-switch operation device for a safety door cover, which includes an equipment housing 11, a cover body 12 and a controller 20. A high-speed rotating mechanism 13 is provided inside the equipment housing 11. The cover body 12 is rotatably connected to the equipment housing 11, and an electric actuator 201 is provided between the equipment housing 11 and the cover body 12.
[0024] Optionally, the equipment is a twisting equipment, an outer winding equipment, a stranding equipment, etc. in steel cord production.
[0025] Optionally, the electric actuator 201 is an electric telescopic rod.
[0026] Furthermore, the controller 20 is provided with a control panel 21. The control panel 21 is provided with a first button 22 and a second button 23. The controller 20 is used to control the operating state of the electric actuator 201. The electric actuator 201 includes an opening motion state and a closing operating state.
[0027] It can be understood that the controller 20 can control the electric actuator 201 to perform telescopic actions, that is, automatically complete the opening and closing actions of the cover body 12. In particular, it is operated through the first button 22 and the second button 23 on the control panel 21. When the cover body 12 is fully opened, after pressing the first button 22 and the second button 23, the controller 20 controls the electric actuator 201 to perform the action of closing the cover body 12. When the cover body 12 is fully closed, after pressing the first button 22 and the second button 23, the controller 20 controls the electric actuator 201 to perform the action of opening the cover body 12.
[0028] Furthermore, the first button 22 and the second button 23 are connected in series in the control circuit of the electric actuator 201. When the first button 22 and the second button 23 are fully pressed, the control circuit of the electric actuator 201 is turned on, and the controller 20 can control the electric actuator 201 to be in the opening motion state or the closing operating state, so that the cover body 12 is opened or closed relative to the equipment housing 11.
[0029] Among them, in order to prevent users from operating the two buttons with one hand, the minimum distance between the first button 22 and the second button 23 is greater than 25 cm.
[0030] In this way, it can prevent most people from directly operating the two buttons with one hand. Users can only operate the two buttons with two hands respectively. For example, press the first button 22 with the left hand and the second button 23 with the right hand, and keep pressing until the cover body 12 is fully closed.
[0031] Such as Figure 2As shown, both the first button 22 and the second button 23 include a first part and a second part. The control circuit of the electric actuator 201 includes a first switch group 202 and a second switch group 203. When the first part and the second part of the first button 22 or the second button 23 are simultaneously pressed, the first switch group 202 or the second switch group 203 closes.
[0032] When the first button 22 and the second button 23 are simultaneously pressed, the first switch group 202 and the second switch group 203 close. Therefore, the control circuit of the electric actuator 201 is turned on, and the electric actuator 201 can perform telescopic actions to complete the opening and closing of the cover 12.
[0033] In an alternative embodiment, the first button 22 and the second button 23 are configured as circular buttons. The first part is configured as a circle, and the second part is configured as a ring. The circular first part is located inside the annular second part.
[0034] In this way, the user can correctly press the first button 22 only by covering the first part and the second part of the first button 22 with the palm. Similarly, the user can correctly press the second button 23 only by covering the first part and the second part of the second button 23 with the palm, so as to prevent the user from using tools such as wrenches to simultaneously press the first button 22 and the second button 23.
[0035] Optionally, both the first switch group 202 and the second switch group 203 include two normally open switches connected in series.
[0036] As Figure 2 shown, in a specific embodiment, the first part of the first button 22 is a circular button A222, and the second part of the first button 22 is an annular button B221. In the corresponding control circuit, the circular button A222 corresponds to the first control switch 22a, and the annular button B221 corresponds to the second control switch 22b. The first part of the second button 23 is a circular button B232, and the second part of the second button 23 is an annular button B231. In the corresponding control circuit, the circular button B232 corresponds to the third control switch 23a, and the annular button B231 corresponds to the fourth control switch 23b. When the circular button A222, the annular button B221, the circular button B232, and the annular button B231 are fully pressed, the first control switch 22a, the second control switch 22b, the third control switch 23a, and the fourth control switch 23b close, turning on the circuit.
[0037] In other embodiments, the first button 22 and the second button 23 can also be configured as circular or square buttons, and the first part and the second part are respectively located on the first side and the second side of the central axis of the square button.
[0038] In this way, the user can only control one of the buttons with a single palm. For example, the left palm presses the first part and the second part of the first button 22, and the right palm presses the first part and the second part of the second button 23.
[0039] Furthermore, the control panel 21 is inclined or perpendicular to the horizontal plane. In this way, the inclined or vertical plane is not conducive to preventing tools, so as to avoid the user using tools to press the buttons.
[0040] Furthermore, on the control panel 21, the trajectory of the line connecting the first button 22 and the second button 23 is non-planar. For example, there are other buttons or convex structures on the line connecting the first button 22 and the second button 23. In this way, it is possible to avoid the user using a rod-shaped tool to press the two buttons to achieve improper operations.
[0041] In the above embodiment, the first button 22 and the second button 23 are set to have a tendency to rebound after the pressure is removed when pressed. Therefore, during the closing process of the cover 12, the user must continuously press on the surfaces of the first button 22 and the second button 23 and cannot leave, otherwise the closing operation cannot be achieved. In this way, the situation of the cover 12 pinching the hand can be avoided.
[0042] Combined with the above embodiments, the present utility model sets the buttons for operating the closing of the cover to two, and the distance between the two buttons is relatively large. It is impossible for the user to operate these two buttons with one hand. Therefore, when closing the cover, the user must press the two buttons with both hands at the same time, and the user cannot press the two buttons with one hand by means of common tools. Therefore, there is no possibility for the user to operate the closing of the equipment cover with one hand, completely eliminating the safety risk when closing the cover, and effectively ensuring production safety.
[0043] Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Those with ordinary knowledge in the technical field to which the present utility model belongs can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to what is defined by the claims.
