BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pipe mounting tightening tool for tightening screws of a hanging band or a stand band, which is used for mounting pipes for air conditioning and the like.

[0002]

2. Description of the Related Art Conventionally, in the work of air conditioning piping in buildings and factories, as shown in FIG. 3, a hanging band 2 and a standing band 3 are set on bolts embedded in a ceiling or a wall, and a pipe 1 is passed through. Using a stepladder, etc., in a high or narrow place,
I was forced into an unnatural posture, and I used two tools, a ratchet wrench and a spanner, to tighten the screws.

[0003]

[Problems to be Solved by the Invention] As described above, the air-conditioning piping work is troublesome, and especially in the screw tightening work, it is necessary to use two tools properly in a high or narrow place, which is inefficient and the tool drop There is also a danger that the worker's mental burden is heavy.

The object of the present invention is to eliminate such drawbacks and to tighten screws of different kinds of suspension bands and stand bands with a single tool, and even if the hand is released during the work. , It is to provide a pipe mounting tightening tool that allows the user to work with peace of mind without fear of the tool falling.

[0005]

In order to achieve the above object, the pipe mounting tightening tool of the present invention is for tightening the screws of the suspension band 2 and the stand band 3 for mounting the pipe 1 on the ceiling or wall surface. In the tool, the ratchet wrench 20 is provided at one end of the common handle 10 and the spectacles 30 are provided at the other end, and the inner wall of the spectacles 30 is formed into a polygonal shape that matches the shape of the nut 4 to be tightened. Set the opening width of 31 a little larger than the bolt diameter, and for the surface that the nut 4 rotates when tightened,
The handle 10 has an angle of about 15 ° to 30 ° with respect to the glasses 30 so that the handle 10 is inclined.

[0006]

Embodiments of the present invention will now be described in detail with reference to the drawings. FIG. 1 is a front view showing an embodiment of the present invention. 2 is a plan view of the embodiment of FIG. In this embodiment, as shown in FIGS. 1 and 2, a ratchet wrench 20 and eyeglasses 30 are integrally formed at both ends of a common handle 10. Ratchet wrench 20
Is a socket 2 for fitting and turning on the suspension band 6.
1, 22 and the socket 21 by the ratchet mechanism,
The direction of rotation of 22 can be changed.

As shown in FIG. 2, the spectacles 30 have a shape in which the inner surface of the spectacles, which contacts the nut, is rotated by 30 degrees about the center of the hexagon that fits the outer side of the nut (hereinafter referred to as double hexagon). ) Is formed by the uneven surface of the groove. The opening width L of the opening 31 is slightly larger than the outer diameter of the bolt. Further, as shown in FIG. 1, the glasses 30 and the handle 10 are formed such that the handle 10 is inclined by 15 °.

When using the glasses of this embodiment, as shown in FIG. 4, after inserting the glasses opening 31 into the bolt 5 portion of the suspension band 2, the glasses portion is lowered and fitted into the nut 4. Turn the nut 4 to attach the suspension band 2 to the bolt 5
Fixed to.

Moreover, the handle 10 is 15 ° with respect to the glasses 30.
Since it is tilted by approximately 30 °, there is no concern that the socket 21 (or 22) of the ratchet wrench 20, the hand holding the handle 10 or the like will be rubbed against the ceiling or the wall, so that the user can work with peace of mind. Also, especially when attaching a suspension band, the height of raising the hand can be as low as the handle is tilted, which reduces fatigue.

Further, even in the continuous tightening work, even if the hands are released while the glasses 30 are still fitted in the nut 4, for example, the thick line portions a, b, c, d and e shown in the explanatory view of FIG. 6 are along the outer surface of the nut. It abuts and is caught and does not fall. 6 and 7 are explanatory views showing the relationship between the glasses 30 and the nut 4, and FIG. 7 is a cross-sectional view taken along line AA in FIG. The portion where the eyeglasses and the nut are in contact is the shaded portion in FIG. 7, and the nut can securely hold the entire tool. This also applies to the case where the nut is hooked outside in the recesses between a and b, b and c, c and d, and d and e in the bold line portions. Therefore, it is possible to efficiently proceed with the continuous tightening work, and it is possible to greatly reduce the risk of the tool coming off from a high place and dropping it.

[0011]

As described above in detail, according to the present invention, the ratchet wrench and the glasses are integrally formed at both ends of the common handle, so that the pipe mounting can be performed by only one tool in the air conditioning work. At the same time, by forming the inner surface of the eyeglasses into a concavo-convex surface that fits the outer shape of the nut to be fitted, it is easy for the eyeglasses to fit into the nut, and the tool does not drop even if you release your hand during work. There is an effect that the work can be performed efficiently without danger. Further, by forming the glasses and the handle at an angle, it is possible to tighten the nuts on the ceiling and the wall surface without difficulty.
