An electric mechanism with electric and manual interlocking

Abstract

This utility model belongs to the field of control, specifically relating to an electric mechanism with electric and manual interlocking. A toggle switch and the power supply circuit of the electric mechanism are connected in series to control the electrical connection or disconnection of the electric mechanism. When the toggle switch is in the ON position, the manual input interface of the electric mechanism is blocked by the toggle switch, preventing manual tools from operating the manual input interface.

Description

Technical Field

[0001] This utility model belongs to the field of control, and specifically relates to an electric mechanism that interlocks electric and manual operation. Background Technology

[0002] Electric mechanisms work by reducing the mechanical energy generated when an electric motor is energized, then converting it into a specified motion form through a reducer and a conversion mechanism to drive the load. Some electric mechanisms are designed with a manual mechanical input interface, which allows manual input to drive the actuator of the electric mechanism to move the load. To avoid misoperation and improve personal safety (such as accidental power-on during manual operation leading to hand injuries), the electrical system needs to be disconnected. The conventional method is to place warning signs at the manual operation port, but this method still has the possibility of misoperation. Therefore, an interlocking method between electric and manual operation is needed to avoid the above problems. Utility Model Content

[0003] Purpose of the utility model: To provide an electric mechanism that interlocks electric and manual operation to prevent misoperation.

[0004] Technical solution:

[0005] An electric mechanism with electric and manual interlocking is provided, wherein a toggle switch and the power supply circuit of the electric mechanism are connected in series to control the electrical connection or disconnection of the electric mechanism. When the toggle switch handle is in the on position, the manual input interface of the electric mechanism is blocked by the toggle switch handle, and manual tools cannot operate the manual input interface.

[0006] Furthermore, when the toggle switch handle is in the off position, the electric mechanism can be switched on or off via a manual input interface using a manual tool.

[0007] Furthermore, the hand tool is L-shaped, with one end being the force-applying end and the other end being the control end.

[0008] Furthermore, the end face of the force-applying end is hexagonal.

[0009] Furthermore, the end face of the control terminal is hexagonal.

[0010] Furthermore, the outer edge of the force-applying end is decorated with patterns.

[0011] Beneficial effects:

[0012] This solution achieves interlocking between electric and manual operation through physical methods. The interlocking performance is reliable and safe, and the mechanism is simple and low-cost, fundamentally avoiding personal safety issues caused by human error. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The described embodiments are only some, not all, of the embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0018] In the description of this utility model, it should be understood that the terms "center", "axial", "vertical", "upper", "lower", "upper end", "bottom end", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting the scope of protection of this utility model.

[0019] The following combination Figure 1 , Figure 2 The present invention will be described in detail as follows:

[0020] The power supply circuits of the toggle switch 1 and the electric mechanism 2 are connected in series to control the electrical on and off of the electric mechanism 2. When the toggle switch is in the on position, the manual input interface of the electric mechanism is blocked by the toggle switch, and manual tools cannot operate the manual input interface.

[0021] When the toggle switch 1's handle 11 is moved to the ON position, the electric mechanism 2 is electrically connected and can be powered on and work normally. However, since the toggle switch 1's handle 11 is located on the docking channel between the manual tool 3 and the manual input interface 21 of the electric mechanism 2, the handle 11 physically blocks the docking between the manual tool 3 and the manual input interface 21 of the electric mechanism 2, thus preventing manual operation of the electric mechanism 2.

[0022] When manually operating the electric mechanism 2, the toggle switch 1's handle 11 must be moved to the off position to clear the connection between the manual input tool 3 and the manual input interface 21 of the electric mechanism 2. The electric mechanism 2 is in an electrically disconnected state and will not operate even when powered on. When the manual input tool 3 is connected to the manual input interface 21 of the electric mechanism 2, the electric mechanism 2 can be manually driven using the manual input tool 3, i.e., manual operation mode. When the manual input tool 3 is connected to the manual input interface 21 of the electric mechanism 2, the toggle switch 1's handle 11 is blocked by the manual input tool 3 and cannot be moved to the on position. This means the electric mechanism 2 remains electrically disconnected and will not operate even when powered on. Only after the manual input tool 3 is removed can the toggle switch 1's handle 11 be moved to the on position, allowing the electric mechanism 2 to operate normally.

[0023] This achieves interlocking between the electric and manual operation of the electric mechanism.

[0024] The manual tool is L-shaped, with one end being the force-applying end and the other end being the control end.

[0025] The end face of the force-applying end is hexagonal.

[0026] The end face of the control terminal is hexagonal.

[0027] The outer edge of the force-applying end is decorated with patterns.

[0028] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
