Description

Technical Field

[0001] The utility model relates to the technical field of power distribution switches, in particular to a power distribution switch for electrical engineering. Background Art

[0002] There are many types of existing power distribution switches, such as air switches, dual power switches, double throw knife switches, control and protection switches, etc. Air switches play the role of overload (overcurrent) and short circuit protection in the circuit. They are composed of operating mechanisms, contacts, protection devices (various trippers), arc extinguishing systems and operating handles. However, when the operating handle breaks due to long-term use or aging, it is not easy to turn the operating handle to close or open the switch, which affects the normal use of the air switch. Utility Model Content

[0003] The utility model mainly provides a power distribution switch for electrical engineering, which solves the problem that when the operating handle of the prior art is broken due to long-term use or aging, it is difficult to rotate the operating handle to close or open the switch, thereby affecting the normal use of the air switch.

[0004] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0005] A power distribution switch for electrical engineering, comprising an air switch body, a shaft rod is arranged on the air switch body, a handle seat is fixedly connected to the shaft rod, a matching notch is opened on the outside of the handle seat, a handle rod section is detachably connected to the shaft rod corresponding to the matching notch, and a stop block matching the matching notch is arranged on the handle rod section. The handle seat can be fixed to the shaft rod in any way, or can be directly sleeved on the outside of the shaft rod when the shaft rod is installed, and other components in the air switch body that need to be connected to the inside of the traditional handle are also connected to the handle seat. With the structure of the present application, the handle rod section and the stop block are installed on the shaft rod in a detachable connection manner, so that when the handle is broken, the handle rod section and the stop block can be replaced without replacing the handle seat, thereby avoiding affecting the subsequent use and improving the overall service life; with the handle rod section and the stop block, positioning and limiting can be performed by the stop block and the matching notch during installation, so as to be installed better, and when the handle rod section is rotated, the side of the stop block will also apply force to the handle seat, so that the handle seat can rotate on the shaft rod.

[0006] Furthermore, the handle bar section and the stop block are integrally formed, and reinforcing ribs are provided inside the handle bar section and the stop block. With this structure, the overall strength of the handle bar section and the stop block can be enhanced by providing the reinforcing ribs, thereby preventing the handle bar section and the stop block from breaking prematurely and extending their service life; and the provision of the reinforcing ribs enables the handle bar section to be moved and the switch to be turned off for replacement when it breaks.

[0007] Furthermore, the stopper is detachably connected to the shaft rod by bolts. This method is simple to assemble and disassemble and has a stable structure.

[0008] Furthermore, the matching notch is fan-shaped. With this structure, the stop block can be easily matched with the matching notch.

[0009] Furthermore, the reinforcing ribs are made of insulating material. With this structure, electric shock can be avoided.

[0010] Beneficial effects: With the structure of the present application, the handle rod segment and the stop block are installed on the shaft rod by means of a detachable connection, so that when the handle breaks, the handle rod segment and the stop block can be replaced without replacing the handle seat, thereby avoiding affecting subsequent use and improving the overall service life; with the handle rod segment and the stop block, positioning and limiting can be performed during installation by means of the stop block and the matching notch, thereby achieving better installation, and when the handle rod segment is rotated, the side of the stop block will also apply force to the handle seat, so that the handle seat can rotate on the shaft rod.
