Abstract

<P>PROBLEM TO BE SOLVED: To provide a handle cover device in which inhibition of handle operation of a circuit breaker is promoted, a separate parts is unnecessary since it is installed inside the circuit breaker body, and an operating state is confirmed when the circuit breaker is in operation. <P>SOLUTION: The handle cover device formed to solve the problem is arranged inside the upper face of the circuit breaker, and consists of a slide plate in which a protruding part fittable in a fitting part installed in the circuit breaker is installed, and an elastic member one end of which is fixed to the slide plate while the other end is fixed to the circuit breaker, and the slide plate is retainable inside the circuit breaker body by the elastic member. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  The present invention relates to a handle cover device.

  Conventionally, when urging prohibition of handle operation in a circuit breaker, a handle lock device has been prepared and attached separately from the circuit breaker body.

  For this reason, a part for locking the handle is required separately from the circuit breaker main body, so it is inconvenient if it is needed immediately, and it may be lost because it is small as a part.

  As an improvement measure, a lock plate is provided in the operation handle of the circuit breaker as described in Patent Document 1, and the lock plate is pulled out when operated on or off, and is formed on the periphery of the opening of the operation handle. It is conceivable to use a handle lock device in which the operation handle is locked by engaging with the groove, and a lock hole is provided in the lock plate, and a padlock can be attached to the lock hole.

Further, as in the invention described in Patent Document 2, a through hole is provided in the front side of the handle on the rotation side, a lock lever is pivotally supported at the substantially lower end of the through hole, and the front end of the lock lever is engaged. When the handle is locked, the lock lever is rotated by turning the engagement part of the lid and the tip of the lock lever. When the engaging part is engaged with each other and fixed and is not locked, the lock lever is housed in the through hole of the handle, and the engaging part provided in the handle and the engaging part of the tip of the lock lever It is conceivable to use a handle lock device that engages and fixes each other.

  However, the invention described in Patent Document 1 has a drawback that the locked state is unstable unless the lock plate is fixed by another component such as a padlock.

  Moreover, since the handle is fixed, there is a disadvantage that the position of the handle does not change even when the circuit breaker is actuated, and it cannot be confirmed from the outside.

  Further, the invention described in Patent Document 2 has a drawback in that since the handle is fixed, the position of the handle does not change even when the circuit breaker is operated, and confirmation from outside cannot be performed.

  For this reason, the problem to be solved by the present invention is to urge prohibition of the operation of the circuit breaker handle, and since it is provided inside the circuit breaker body, no separate parts are required and the circuit breaker operation is It is an object of the present invention to provide a handle cover device capable of confirming an operation state.

  The handle cover device of the present invention made to solve the above-described problem is a handle cover device disposed inside the upper surface of a circuit breaker, and the handle cover device is a fitting portion provided in the circuit breaker. It consists of a slide plate provided with a protrusion that can be fitted into the slide plate, and an elastic member with one end fixed to the slide plate and the other end fixed to the circuit breaker. The slide plate can be held inside the circuit breaker body by the elastic member. It is what.

  According to the handle cover device of the present invention, it is possible to prompt the prohibition of the handle operation of the circuit breaker.

  In addition, since it is not necessary to prepare parts separately from the circuit breaker, there is no need to search for it when used, and there is no risk of loss.

  Also, when the circuit breaker is activated, the slide plate is pushed by the rotated handle and the projection part is removed from the fitting part, and is pulled by the telescopic member and held inside the circuit breaker. Is possible.

  In the present invention, the handle cover device provided in the circuit breaker is made possible with a simple structure.

Embodiments of the present invention will be described below.
A handle cover device disposed inside the upper surface of the circuit breaker 1, 11, 21, 31 and the handle cover device includes fitting portions 3, 13, Slide plate 2, 12, 22, 32 provided with projections 4, 14, 24, 34 that can be fitted in 23, 33, and one end is fixed to slide plate 2, 12, 22, 32, and the other end is shut off. The springs 15 and 25 are fixed to the devices 1, 11, 21 and 31, and the slide plates 2, 12, 22 and 32 can be held inside the circuit breakers 1, 11, 21 and 31 by the springs 15 and 25. By doing so, the slide plates 2, 12, 22, and 32 can be pulled out only when necessary to urge the operation prohibition of the handles 6, 16, 26, and 36, and there is no need to prepare separate parts. Eliminate the risk of loss Can.

  The handle cover device is disposed inside the upper surface of the circuit breaker 41. The handle cover device has a protrusion 43 that can be fitted into a fitting portion 44 provided inside the circuit breaker 41 in the direction of pulling out the bottom surface. And a spring having one end fixed to the slide plate 42 and the other end fixed to the circuit breaker 41. The spring 42 can hold the slide plate 42 inside the circuit breaker 41 main body by the spring. Only when necessary, the slide plate 42 can be pulled out to urge the prohibition of the operation of the handle 46, and since there is no need to prepare a separate part, the possibility of loss can be eliminated. Moreover, since the part which protruded outside the circuit breaker 41 main body is not provided, it is possible to prevent the slide plate 42 from returning to the inside of the circuit breaker 41 main body due to catching or the like.

  As described above, the handle cover structure according to the present invention prompts the prohibition of the operation of the handle in the circuit breaker, and does not require a separate part, and a simple handle cover device that can confirm the operation state is provided. It can be provided in structure.
