[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 4As shown, an embodiment of the present invention provides an anti-accidental touch switch device, which includes a switch body 10 and a protection component 20. The switch body 10 has a base 11, a gate rod 12 and a rotating shaft 13. The rotating shaft 13 is rotatably arranged on the base 11. The gate rod 12 is connected to the rotating shaft 13. The gate rod 12 is swingably arranged on the base 11 through the rotating shaft 13. The rotating shaft 13 rotates around a first direction to switch the switch body 10 from a power-on state to a power-off state. The rotating shaft 13 rotates around a second direction opposite to the first direction to switch the switch body 10 from a power-off state to a power-on state. State, the protection component 20 includes a rotating member 21, a limit member 22 and a locking member 23. The rotating member 21 is arranged at one end of the rotating shaft 13 and rotates synchronously with the rotating shaft 13. The limit member 22 is movably arranged on the base 11. When the rotating member 21 rotates, it drives the limit member 22 to move. The locking member 23 is arranged on the base 11. When the rotating shaft 13 and the rotating member 21 rotate around a first direction, the locking member 23 avoids the limit member 22. When the rotating shaft 13 and the rotating member 21 rotate around a second direction, the locking member 23 stops the limit member 22 to prevent the switch body 10 from switching from a power-off state to a power-on state.

[0033] The anti-mistaken-touch switch device provided by the present embodiment is applied, and the anti-mistaken-touch switch device includes a switch body 10 and a protection component 20. The switch body 10 includes a base 11, a gate rod 12 and a rotating shaft 13. The rotating shaft 13 is rotatably arranged on the base 11, the gate rod 12 is connected to the rotating shaft 13, and the valve stem can be swingably arranged on the base 11 when the rotating shaft 13 rotates. When the rotating shaft 13 rotates around a first direction, the switch body 10 can be switched from a power-on state to a power-off state. When the rotating shaft 13 rotates around a second direction opposite to the first direction, the switch body 10 can be switched from a static state to a power-on state. Among them, the rotating member 21 is rotatably arranged at one end of the rotating shaft 13 and can drive the limit member 22 to rotate. The limit member 22 can be locked and matched with the locking member 23, thereby preventing the switch body 10 from being switched from a power-off state to a power-on state. Specifically, when the switch body 10 is switched from the power-on state to the power-off state, the rotating shaft 13 and the rotating member 21 can rotate around the first direction, and the locking member 23 can avoid the limit member 22. When the staff operates the valve stem to drive the switch body 10 to switch from the power-off state to the power-on state, the locking member 23 can stop the limit member 22, and can prevent the staff from switching the switch body 10 from the power-off state to the power-on state. In this way, when the maintenance personnel are repairing the line, it can be prevented that the staff accidentally controls the swing of the gate rod 12, and then avoids switching the switch body 10 from the power-off state to the power-on state, thereby ensuring the personal safety of the maintenance personnel and improving the practicality and structural reliability of the anti-mistouch switch device.

[0034] It should be noted that the rotating shaft 13 rotates around a first direction, the first direction is a clockwise direction, and the rotating shaft 13 rotates around a second direction, the second direction is a counterclockwise direction.

It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0048] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the devices or elements referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention. The directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0049] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0050] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.
