Abstract

PROBLEM TO BE SOLVED: Some electronic appliances that are increasing in a company or a general household want to be managed by restricting or prohibiting use. For example, unauthorized use of electrical appliances in companies, etc., and long-term use of televisions and television games at home. Therefore, a power plug cover for managing the use of electrical appliances is provided.
A box body is formed of an insulating material such as synthetic resin, and a storage portion and an insertion hole for storing a contact piece of a power plug are formed. The storage portion communicates with the perforation of the contact piece of the power plug. A hole to be formed is provided, and after the hole of the power plug is communicated with the hole, the lock pin is passed through and locked.

Description

  The present invention relates to a power plug cover, and more particularly, to lock the power plug to restrict insertion into an outlet and manage the use of electrical appliances.

As a power plug locker, there is a box made of a synthetic resin material having a lock pin that engages with a perforation of a contact piece of the power plug. (See Japanese Utility Model Publication No. 64-1480)
In addition, there is a padlock in which the vine part is locked by directly penetrating the perforation of the contact piece of the power plug, and the vine part is covered with an insulating film. (Refer to Japanese Utility Model Publication No. 8-6986)
Japanese Utility Model Publication No. 64-1480 No. 8-6986

  Various types of electrical appliances are also increasing in companies and general households. Among them, there are electrical appliances for personal use and electrical appliances whose use is restricted. For example, it is necessary to take some measures against electric shocks and fires caused by long-term use of televisions and television games, mischief of infants, or unauthorized use of electric appliances in companies, factories, work sites, and the like.

  In the device described in Japanese Utility Model Publication No. 64-1480, the contact piece of the power plug is inserted into the box, the lock pin attached inside the box is engaged with the hole of the power plug and locked, and unlocking is performed by the key. Thus, the cam in the box is rotated to spread the lock pin.

  However, a box, a lock pin, a cam, and a dedicated key are required, and the number of members increases, and an operation for attaching the lock pin and the cam to the box is required, resulting in a production cost.

  The device described in Japanese Utility Model Publication No. 8-6986 discloses that a padlock having a vine covered with an insulating film is directly passed through a hole of a contact piece of a power plug. However, since the contact piece of the power plug is exposed even when locked, there is a possibility that the child may try to insert the power plug into the outlet forcibly or pull it to remove the key. There is a danger that the tip of the plug may come into contact with the outlet and energize.

  Therefore, the present invention provides a power plug lock cover that covers the entire contact piece of the power plug with a cover, protects the contact piece, and makes it impossible to physically insert the plug into the outlet and manage the use of electrical appliances. The purpose is to do.

  In order to solve the above problems, in the present invention, a power plug cover made of an insulating material is provided with a hole communicating with the perforation of the contact piece, and the power plug contact piece is covered with the cover and then communicated. A lock pin such as a padlock vine is passed through the hole and locked.

1. Unauthorized use and long-time use of electrical appliances can be prohibited and their use can be managed.
2. Prevent mischief of infants and other electrical appliances and prevent electric shock and fire.
3. The power plug itself can be covered and protected.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, exemplary embodiments of the invention will be described with reference to the drawings.

  FIG. 1 is a perspective view of a power plug cover-1 (hereinafter simply referred to as “cover”) according to the present invention.

  The cover-1 is a box made of an insulating material, such as a synthetic resin, and is inserted into a leg 3-3 that houses a pair of contact pieces 6-6 of the power plug 5 (FIG. 2). A mouth 2-2 is provided. The storage portion 3-3 is provided with a perforation 4-4 for inserting the temple 9 of the padlock 8 (FIG. 3).

  2 and 3 are explanatory diagrams for explaining the use state of the cover-1.

  The power plug 5 is removed from the outlet, and the contact piece 6-6 is inserted from the access hole 2-2 of the cover 1, and the cover 1 is put on the power plug 5 while being inserted so as to be stored in the storage portion 3-3. Next, the lock 9 of the padlock 8 is inserted and locked so as to pass through the hole 7-7 of the plug contact piece and the hole 4-4 of the cover-1.

  Although FIG. 3 illustrates a cylinder-type padlock, any type of key may be used as long as it has a lock pin that penetrates the hole.

  FIG. 4 is a perspective view showing another embodiment of the present invention.

  The power plug cover is a box 10 having two storage portions 10a, and has two insertion holes 11 for inserting contact pieces of the power plug into the storage portion 10a. The storage portion 10a is provided with a lateral hole 12 that communicates with the perforation of the plug contact piece. After covering the contact piece of the power plug with the cover 10, it is communicated with the perforation (not shown) of the plug contact piece. A padlock or other vine is inserted into the horizontal hole 12 and locked.

  The present invention relates to a power plug lock cover, which is used when managing or restricting the use of electrical appliances, and prevents children from tampering with electrical appliances. It can be used as an instrument to prevent fire.
