Description

[Detailed description of the invention] (Industrial application field) In the invention, the on / off operation handle protruding from the lid of the circuit breaker is inadvertently turned on / off at each of the on / off positions. BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circuit cover for a circuit breaker and a locking device for preventing the circuit breaker.

(Prior Art) Conventionally, as a handle cover locking device for a circuit breaker, for example, as shown in FIGS. 4 and 5, a handle 1 is formed on a handle cover 2 with a cap-shaped handle cover 2 covered. After the lock pin 4 is inserted into the pin hole 3, a cylinder lock 6 is hooked on a key insertion hole 5 formed in the handle cover 2 so as to prevent the lock pin 4 from being removed from the pin hole 3, as shown in FIG. As shown in FIG. 8 to FIG. 8, a cap type handle cover 7 is inserted from above the handle, not shown, or as shown in FIG. 9 to FIG. There is a one-touch type in which the protrusion 9 is fitted and the handle is held from both sides thereof.

(Problem to be Solved by the Invention) In this case, in the case of the handle cover locking device shown in FIGS. 4 and 5, the handle 1 can be sealed and restrained so that the manual operation cannot be performed. Requires a lock pin 4 and a cylinder lock 6,
As a result, there is a disadvantage that the handle cover / lock device is too expensive for its function, and FIGS.
In the case of the handle cover / lock device shown in FIGS. 8 and 9 to 12, it can be easily mounted, but it can be easily attached and detached and urges the prohibition of operation, and cannot fulfill the role of sealing and restraining. There was a drawback to say.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a handle cover / lock device for a circuit breaker which can promote the operation prohibition, and can also serve as a restraint and a substantial seal, even though the number of components is one. It is in.

(Means for Solving the Problems) In order to solve the above problems, the configuration of the present invention includes a handle that protrudes from a lid of a circuit breaker to an on / off position in a direction along the surface thereof, and the handle. A handle cover that can be fitted at each of the ON / OFF positions of the handle, and locks the handle in the fitted state; a string formed integrally with the handle cover; and the handle cover formed by the string. And a lock pin integrally formed with the string-shaped body, wherein the handle cover, the string-shaped body and the lock pin are integrally formed of soft plastic, and the handle cover is provided with a handle of the circuit breaker. When the lock pin is fitted at the on or off position, the lock pin is fitted into a hole formed at the tip of the handle, and the handle and the handle cover are engaged. A handle cover and lock device for a circuit breaker, characterized in that the fitting state of the handle cover can be locked.

(Operation) The handle cover for the circuit breaker thus configured
In the case of the lock device, in a state where the handle cover is not attached to the handle, the handle can be easily slid to the on / off position of the circuit breaker by manual operation, and the circuit breaker can be turned on / off.

Next, when the handle located at one of the on and off positions is locked at that position, a lock pin integrally formed with the handle cover is formed at the tip of the handle while the handle cover is placed over the handle at that position. The handle can be easily locked at one of the ON and OFF positions by fitting the handle into the hole.

When releasing the lock, the handle pin can be removed from the handle with the lock pin removed from the tip end hole of the handle, so that the on / off operation of the handle with respect to the circuit breaker can be easily returned. it can.

(Effects of the Invention) As a result, the present invention has an effect that, in spite of the fact that the number of parts is one, in addition to promoting the prohibition of the operation of the handle of the circuit breaker, it can also easily fulfill the role of restraint and substantially sealing. There is.

(Embodiment) Next, the configuration of a first embodiment of the present invention will be described with reference to FIGS.

A handle 13 protruding from the lid 12 of the circuit breaker 11 so as to be slidable to an on / off position along the surface thereof
The handle cover 14 is fitted to the handle 13 of the circuit breaker 11 at each of the on / off positions of the soft plastic molded handle cover 14 that can be fitted at each of the on / off positions. A recess formed at the tip of the handle 13, in this case, a lock piece that can be fitted into and released from the pin hole 15, in this case, the lock pin 16 is integrally formed in a state where the lock pin 16 is connected by the string-like body 17. I have.

 Next, the operation of the present embodiment will be described.

The handle cover for the circuit breaker thus configured
In the case of the lock device 18, in a state where the handle cover 14 is not attached to the handle 13, the handle 13 easily slides to the on / off position of the circuit breaker 11 by manual operation, and turns on / off the circuit breaker 11. be able to.

Next, when the handle 13 located at one of the ON and OFF positions is locked at that position, the handle 13 at that position is covered with the handle cover 14, and the lock pin 16 integrally formed with the handle cover 14 is By fitting into a pin hole 15 formed at the tip of
Can be easily locked to one of the ON and OFF positions.

To release the lock, remove the lock pin 16 from the pin hole 15
By detaching the handle 14 from the handle 13, the on / off operable state of the handle 13 with respect to the circuit breaker 11 can be easily returned.

As a result, in the case of the handle cover locking device 18, the circuit breaker is used despite the fact that the number of parts is one.
In addition to prompting prohibition of operation of the handle 13 of 11, the role of restraint and substantially sealing can be easily achieved.
