Description

Technical Field

[0001] The utility model relates to the technical field of switch equipment, and more specifically, to a switch equipment opening and closing state indicating mechanism. Background Art

[0002] When the switch device is performing opening and closing actions, it will need to use indicator signs to display the current working status, so the staff can understand the current status of the switch device by observing the indicator signs.

[0003] At present, a Chinese patent with a publication (announcement) number of CN219085878U discloses an indication mechanism and a switch, which includes a first turntable cam, a first linkage rod, a first clamping mechanism and a first indication part; the first turntable cam includes a first disc part and a first main protrusion; the first linkage rod includes a first hinge part, a first contact part and a first driving part; the first clamping mechanism includes a first elastic end; the first indication part includes a first state mark and a second state mark. One end of the first hinge part is fixedly connected to the first contact part, the other end of the first hinge part is fixedly connected to the first driving part, the first linkage rod can rotate around the first hinge part, the first elastic end contacts the first linkage rod and is configured to apply a clamping force to the first linkage rod so that the first contact part contacts the first turntable cam, and the first driving part is connected to the first indication part and is configured to drive the positions of the first state mark and the second state mark of the first indication part to change.

[0004] In the above patent, when the first turntable cam rotates, since the first contact portion contacts the first turntable cam, when the first main protrusion contacts the first contact portion, it will drive the first linkage rod to rotate around the first hinge portion, thereby causing the first drive portion to be displaced, thereby driving the position of the first state mark and the second state mark of the first indication portion to change. When the shell accommodating the indication mechanism is provided with a window that only exposes one state mark, the user can see the switching between the first state mark and the second state mark when the position of the first state mark and the second state mark changes, thereby providing an intuitive and reliable indication mechanism for the switch. However, the state switching of the first state mark and the second mark is achieved by the contact between the first main protrusion and the first contact portion. Therefore, the processing accuracy and assembly requirements for the first turntable cam are relatively high. Moreover, after a certain period of use, the first turntable cam will be slightly worn or misaligned, which affects the matching accuracy of the first turntable cam and the first contact portion, thereby causing the two state marks to be partially exposed in the window, making it impossible for the staff to correctly distinguish the current open and closed state of the switch device.
