Double operation handle apparatus

Abstract

The invention provides a dual operation handle device which comprises a base that is provided with rotary shafts, a main operation handle and a coupled component, wherein, the main operation handle and the coupled component are respectively arranged on one of the rotary shafts and respectively provided with convex edges which are matched with each other; when the main operation handle is operatedto rotate around the rotary shafts, the coupled component is driven by the convex edges which are matched with each other to rotate around the rotary shafts; the dual operation handle device also comprises an assistant operation handle arranged on the rotary shafts and sharing the same circle with the main operation handle; the assistant operation handle is provided with at least one tooth; the coupled component is also provided with at least one tooth meshed with the tooth of the assistant operation handle; when the assistant operation handle is operated to rotate around the rotary shafts, by the driving of the teeth meshed with each other, the coupled component rotates around the rotary shafts. The linkage mechanism connected with the coupled component can be driven through operating the assistant operation handle independently, thereby saving the operation of the main operation handle or the influence of the current state of the main operation handle.

Description

technical field [0001] The invention relates to an accessory of a low-voltage electrical appliance, in particular to an operating handle device of a low-voltage switch. Background technique [0002] In a low-voltage switch, such as an alarm switch, there is usually an operating handle device, which is used to drive a linkage mechanism to open or close a switch contact. [0003] figure 1 A schematic structural view of a typical existing operating handle device 100 is shown. The operating handle device 100 includes a base 10; an operating handle 20 disposed on the base 10; and disposed on the base 10; connected to a linkage mechanism 200 and driven by the operating handle 20 The coupling 30. [0004] A rotating shaft 12 and a rotating shaft 14 are arranged on the base 10 . The operating handle 20 includes a handle 22, a body 24 and a flange 26 connected in sequence; wherein, the handle 22 is used to accept the operation of the external force, and a hole 242 is set on the b...

Problems solved by technology

[0006] However, in the above-mentioned existing operating handle device 100, if it is necessary to drive the linkage mechanism 200 to open or close the switch contact, it has to be realized by operating the operating handle 20, that is to say, if you want to To change the state of the switch contact, it is necessary to change the state of the operating handle 20

However, in practical applications, when it is not desired to change the state of the operating handle 20, or it is not suitable to operate the operating handle 20, but it is necessary to drive the linkage mechanism 200 to open or close the switch contact, the existing operation The handle device 100 cannot meet the above-mentioned operation requirements
