Description

[Detailed Description of the Invention] This invention relates to an enclosing device suitable for enclosing, for example, a water main tap.

Traditionally, water supply interruptions due to moving, non-payment, etc. have been carried out by specialized staff of the waterworks bureau checking the meter and then turning off the main water tap, and the same applies if there is a request to resume water supply. The bottle was opened by specialized staff.

However, since anyone can open the main water tap, there are many instances where water theft can be committed, and users often request that the tap be opened immediately after paying a delinquent bill.
In such cases, it would be inconvenient to leave the work of opening the taps only to specialized staff, and it is preferable that other staff members of the Waterworks Bureau also be able to open the taps.

Therefore, this device has an operating rod at its tip which has a pair of operating pieces whose bases are pivotally connected with a pin, a passageway into which the operating rod is inserted, and windows arranged opposite to each other on the sides of the passageway. When the operating piece is inserted into the cylinder and reaches the window, the operating piece projects out of the window by an opening/closing means provided on the operating piece or a stopper provided at the end of the passage. A screwdriver tool with a screwdriver tool and the above-mentioned operating piece of the screwdriver tool are fitted together as shown in Fig. 2.A bolt for enclosing the screwdriver tool is inserted into the head and legs, and a bottom section has a guide groove for passing the shaft of a main stopcock, etc. A screw hole is formed in the bottom member to screw the leg of a bolt for opening and closing the enclosure, and a head of the bolt is formed on the inner periphery of the cover member. forming a support piece;
In addition, the present invention proposes an enclosure device for a water supply main stopper, etc., which comprises an enclosure for a main stopper, etc., which has a receptacle for inserting the cylinder of the screwdriver tool, formed on the upper surface of the cover member above the support piece. It is.

That is, according to this invention, when the driver tool is inserted into the insertion hole formed in the enclosure and pushed into the head of the bolt at the bottom end of the cylinder, the operating piece pivoted with a pin at the bottom of the operating rod opens the window. It protrudes outward and fits into the groove formed in the head of the bolt.

Then, when the driver tool is rotated, the leg of the bolt is screwed into the screw hole formed in the bottom member, the enclosure is closed, and the main tap of the water supply etc. is enclosed in the container.

Further, in order to open the container, it is sufficient to insert a screwdriver tool into the insertion hole formed in the container and release the bolt screwed into the screw hole from the screw hole in the same manner as described above.

Therefore, according to this invention, the enclosure container can be opened and closed only by using the screwdriver tool, so the main stopper is not manipulated arbitrarily, and anyone can open and close the main stopper by using this screwdriver tool at the same time. Since the container can be opened and closed, the work of opening and closing the main valve can be outsourced to persons other than specialized personnel.
