Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a spanner used when operating a gas cylinder of oxygen, acetylene, or the like.

[0002]

[Prior art]

 A monkey wrench for attaching / detaching the gas pressure regulator and a box wrench for opening / closing the cock are used separately.

[0003]

[Problems to be solved by the device]

 When using oxygen and acetylene general high-pressure gas cylinders, it is necessary to attach a pressure regulator and open and close the cock.However, since the pressure regulator is attached and detached by tightening and loosening with a large diameter nut, Use a flat type monkey wrench, etc. as described above.When opening and closing the cock, the cock is surrounded by a protective cylinder to prevent gas leakage accidents due to damage due to careless handling during transportation. A box spanner that fits inside the protective cylinder is used, and it is not only complicated because it requires two types of spanners, but it is often lost, and it is necessary to search for it each time it is operated.

In view of the above, the main object of the present invention is to provide a spanner suitable for both operations.

[0005]

[Means for Solving the Problems]

 The gas cylinder operating spanner for satisfying the above purpose is provided with an engaging portion at one end of the spanner body that fits the diameter of the detaching nut of the pressure regulator, and has a rod body at the other end in a direction orthogonal to the spanner body. It is fixedly provided with fitting holes on both end faces of the rod for engaging with the open / closed screw lever square head of the cock, and the spanner body is locked with an annulus to connect a string body such as a chain continuously. A large-diameter ring is attached to the other end of the cylinder to attach to the protective cylinder of the cylinder, and a display tag that indicates the name of the contents of the cylinder and the status during operation such as when the cock is opened or closed and during operation It also has a holder that holds the gas leakage prevention packing.

[0006]

[Action]

 Hook a large-diameter ring on the protective cylinder of the gas cylinder, fit the engagement part of the wrench body into the removable nut of the pressure regulator and tighten it to mount it on the cylinder. Select `` Medium '' or `` Not in operation '' and store it in the holder, and also store packing for gas leak prevention.When using gas, fit the open / close screw rod head into the fitting hole provided in the rod of the nut body. And loosen the cock to supply gas.

[0007]

【effect】

 The gas cylinder operating wrench according to the present invention is provided with a spanner body for engaging and disengaging the pressure regulator and a rod body provided with a fitting hole for opening and closing the cock. No need to use the tightening tool of the above, and the large-diameter ring that is hooked on the protective cylinder cannot be removed from the gas cylinder by mounting the pressure regulator. Since it is not lost because it is present, it is rich in workability, and on the other hand, the usage status is displayed on the display tag, which is also beneficial for safety.

[0008]

【Example】

 FIG. 1 shows an embodiment of a gas cylinder operating wrench according to the present invention. FIG. 1 is a perspective view and FIG. 2 is a usage state diagram. Description will be given below with reference to the drawings.

Reference numeral 1 in the drawing is a wrench body, in which one end of the wrench body 1 is provided with an engaging portion 2 adapted to the diameter of the attachment / detachment nut A1 of the pressure regulator A, and the other end of which is attached to the wrench body 1. Fitting holes that are fixed to the substantially central portion of the rod 3 that is orthogonal to each other and that engage with the opening and closing screw rod head B2 of the cock B1 of the gas cylinder B of oxygen, acetylene or the like on both end faces of the rod 3 have different diameters. 4, 4'are provided.

An annular body 5 is locked to the spanner body 1 so as not to come out from both ends, and one end of a cord body 6 such as a chain is fixed to the annular body 5 and the other end of the cord body 6 is fixed. Secures the large-diameter ring 7 that is hooked to the protective cylinder B3 that surrounds the cock B1 of the gas cylinder B, and the holder 8 is hooked to the cord 6 near the large-diameter ring 7 so that the holder 8 In the transparent bag part 8'of, for example, the name of the contents of the gas cylinder B, the person in charge of handling, or "open" or "in use" associated with the opening and closing of the cock B1 is shown on the front side, and "closed" or "not in use" is indicated on the back side. The display tag 9 that describes the situation at the time of operation such as described in, and the gas leakage prevention packing 10 that is interposed between the detaching nut A1 of the pressure regulator A and the branch pipe of the cock B1 are stored. is there.

The embodiment has the above-mentioned structure, the large-diameter ring 7 is hooked on the protective cylinder B3 of the gas cylinder B, and the detachable nut A1 of the pressure regulator A is applied to the branch pipe of the cock B1. The engaging portion 2 of the spanner body 1 is fitted and tightened onto the detachable nut A1, and the indicator tag 9 in the holder 8 is displayed by selectively indicating whether it is in use or not in operation according to the use situation. Etc. are stored, and when using gas, loosen the cock B1 with the fitting hole 4 that fits the diameter of the opening / closing screw rod square head B2 among the fitting holes 4 and 4'provided in the rod 3 of the nut main body 1 To supply.

Although the oxygen or acetylene gas cylinder has been described in the embodiments, it goes without saying that it can be applied to a cylinder containing draft beer as well as general high pressure gas such as carbon dioxide and argon.

However, the gas cylinder operating spanner according to the embodiment includes the engagement portion for detaching and attaching the pressure adjuster and the rod body provided with the fitting hole for opening and closing the cock in the spanner body. There is no need to use a separate tightening tool during operation, and the large-diameter ring that is hooked on the protective cylinder does not come off from the gas cylinder due to the mounting of the pressure regulator, and the large-diameter ring and spanner body are connected by a string. Since it does not get lost, it is highly workable, and on the other hand, the usage status is displayed on the display tag, which also contributes to safety.
