Description

Handcart type vacuum circuit breaker operating handle

technical field

The utility model relates to an operating handle of a circuit breaker, in particular to an operating handle of a handcart type vacuum circuit breaker.

Background technique

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.

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 be done with a manual operating handle. There are many existing operating handles, but they are generally irregular in shape and large in size, so it is inconvenient to use and store, and may be often lost.

Utility model content

The purpose of the utility model is to provide a handcart-type vacuum circuit breaker operating handle to solve the problem that the existing operating handle is inconvenient to store and easy to lose.

In order to achieve the above purpose, the utility model adopts the following technical scheme: a handcart-type vacuum circuit breaker operating handle, the handle is composed of a handle, a tool shaft and a transmission rod, and one end of the tool shaft is integrally provided for connecting with the vacuum circuit breaker. The handcart operation hole cooperates with the connector used for installation, the other end is hinged with one end of the transmission rod, and the other end of the transmission rod is hinged with the connection end of the handle; the tool shaft and the hinged end of the handle and the transmission rod are all provided with a stop table , the handle, transmission rod and tool shaft are in a "Z" shape when folded, and in a "1" shape when stretched.

Both ends of the transmission rod are provided with a fork-shaped structure, and the tool shaft and the handle are fork-connected with the fork-shaped structure at the corresponding end of the transmission rod through the fork block provided at the hinged end, and are connected to the transmission rod through the corresponding straight pins respectively. hinged.

The section of the connecting head is a hexagonal structure.

The tool shaft of the handcart type vacuum circuit breaker of the utility model and the hinged end of the handle and the transmission rod are all provided with a stop table for positioning, so that the handle, the transmission rod and the tool shaft are in a "Z" shape when they are folded. When extended, it has a "1" shape structure; the handle rotates and articulates the handle, tool shaft and drive shaft to each other, realizing the integration of the circuit breaker handcart and the operating handle, which is very simple, small in size and easy to store, avoiding the need for operation The handle is easy to lose, and at the same time, the appearance of the product is improved, and the operation of the circuit breaker handcart becomes convenient and fast.

In addition, the corresponding fork-shaped structure on the transmission rod is used to connect with the fork-shaped block on the handle and the tool shaft, and they are hinged through cylindrical pins to realize the transmission of torque.

Detailed ways

The utility model is further introduced below in conjunction with specific embodiments.

Figures 1 to 2 are the structural diagrams 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, and one end of the tool shaft is integrally equipped with a The other end of the connector 6 used in conjunction with the handcart operating hole of the vacuum circuit breaker is hinged to one end of the transmission rod 3, and the other end of the transmission rod 3 is hinged to the connecting end of the handle 1; the tool shaft 5 and the handle 1 are connected to the transmission rod The hinged ends of 3 are all provided with a stop table, and the handle, transmission rod and tool shaft are in a "Z" shape when folded, and in a "1" shape when stretched.

Both ends of the transmission rod 3 are provided with a fork-shaped structure, and the handle 1 and the tool shaft 5 are fork-connected with the fork-shaped structure at the corresponding end of the transmission rod through the fork blocks 7 and 8 provided at the hinged ends of the handle 1, and pass through the corresponding cylinders respectively. Pins 2 and 4 are hinged with transmission rod 3 . The cross-sectional shape of the connector 6 matches the shape of the operating hole of the circuit breaker trolley, and the cross-section of the connector in this embodiment is a regular hexagon.

The operating handle is "Z"-shaped when in use and "┃"-shaped when stored (as shown in Figure 1-2), which is convenient, flexible and beautiful in appearance. A slot can be opened on the circuit breaker panel for storage, avoiding the Separation of operating handle and circuit breaker.

When operating the handcart of the circuit breaker, take the operating handle out of the circuit breaker panel groove. At this time, the state of the operating handle is shown in Figure 1. Change the operating handle to the shape shown in Figure 2. Hold the handle 1 and connect the tool shaft 5 to the connector. The hexagonal shaft of the circuit breaker handcart is inserted into the operating hole of the circuit breaker handcart, and the handle 1 is rotated. The torque acts on the propulsion and withdrawal mechanism of the circuit breaker handcart through the transmission rod 3, the second and the tool shaft 5, so as to realize the connection of the circuit breaker handcart. and isolation.

After the operation is completed, stretch the operating handle into the shape shown in Figure 1 and store it in the groove of the circuit breaker panel.

The handcart-type vacuum circuit breaker operating handle of the utility model realizes the integration of the circuit breaker handcart and the operating handle, is convenient for storage, avoids the phenomenon that the operating handle is easy to lose, improves the appearance of the product, and makes the operation of the circuit breaker handcart easier. become convenient and fast.
