Example Embodiment

[0012] The present invention will be further introduced below in conjunction with specific embodiments.

[0013] Such as Figure 1 ~ Figure 2 Shown is the structure diagram of the operating handle of the handcart type vacuum circuit breaker of the present invention. It can be seen from the figure that the handle is composed of a handle 1, a tool shaft 5 and a transmission rod 3. One end of the tool shaft is integrated with the vacuum circuit breaker handcart The operating hole is matched with the connecting head 6 used for installation, the other end is hinged with one end of the transmission rod 3, and the other end of the transmission rod 3 is hinged with the connection end of the handle 1. The tool shaft 5 and the hinged end of the handle 1 and the transmission rod 3 are all provided with Stop the table, and the handle, drive rod and tool shaft are in a "Z"-shaped structure when folded, and in a "1"-shaped structure when stretched.

[0014] Both ends of the transmission rod 3 a...

Abstract

The invention relates to an operating handle for a handcart type vacuum circuit breaker. The handle consists of a handle, a tool shaft and a transmission rod, wherein one end of the tool shaft is integrally provided with a connector matched with a handcart operating hole of the vacuum circuit breaker, while the other end is hinged with one end of the transmission rod; the other end of the transmission rod is hinged with a connected end of the handle; hinged ends of the tool shaft, the handle and the transmission rod are provided with a stop tabletop respectively; and when the handle, the transmission rod and the tool shaft are folded, a Z-shaped structure is formed, and when the handle, the transmission rod and the tool shaft are extended, an I-shaped structure is formed. By mutually rotatably connecting the handle, the tool shaft and the transmission rod, the handcart and the operating handle of the circuit breaker are integrated, and the operating handle is simple in structure, small in volume and convenient to store, and is prevented from being lost; meanwhile, the product appearance is improved, and the handcart of the circuit breaker is convenient and quick to operate.

Description

technical field [0001] The invention relates to an operating handle of a circuit breaker, in particular to an operating handle of a handcart type vacuum circuit breaker. Background technique [0002] The handcart type circuit breaker, simply put, is a circuit breaker that installs the high-voltage switch on a special handcart. The circuit breaker is installed on the withdrawable handcart. Because the handcart cabinet has good interchangeability, Therefore, the reliability of power supply can be greatly improved. If this one is broken, it can be replaced with a spare handcart. [0003] The handcart vacuum circuit breaker generally adopts a screw nut mechanism, through which the connection and disconnection of the power line can be realized. The realization of this kind of movement usually has two kinds of manual and electric, and the majority is manual, but the ones with electric functions must also be able to realize manual operation at the same time. Manual operation must...
