Abstract

(57) [Summary] [Purpose] A ratchet wrench and box wrench are combined into one tool for attaching pipes in air conditioning piping work, etc., the handle of the glasses is angled, and the inner surface of the glasses conforms to the outer shape of the nut. The uneven surface makes it easier to tighten the nuts on the ceiling and walls, and prevents the tool from falling off the nuts even if you release your hand during work. [Structure] Ratchet wrench 20 and eyeglasses 30 are integrally formed on both ends of a handle 10, and the inner surface of the eyeglasses 30 is attached to a nut 4.
It is formed on an uneven surface such as a double hexagon that conforms to, and the eyeglass opening is made slightly larger than the diameter of the bolt 5. Glasses handle 1
0 has an angle of about 15 ° to 30 ° with respect to the nut tightening surface.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pipe mounting tightening tool for tightening a screw of a suspension band or a stand band, which is used for mounting a pipe such as an air conditioner.

[0002]

[Prior Art]

 Conventionally, in the work of air conditioning piping in buildings and factories, as shown in Fig. 3, the hanging band 2 and the standing band 3 are set on the bolts embedded in the ceiling or wall, and the pipe 1 is passed through. They were forced to take an unnatural posture in high or narrow places, and tightened the screws using two tools, a ratchet wrench and a spanner.

[0003]

[Problems to be solved by the device]

 As mentioned above, air-conditioning piping work is troublesome, especially when tightening screws, it is necessary to use two tools properly in a high or narrow place, which is inefficient, and there is a risk of tool dropping, which is the spirit of the worker. There was a drawback that the physical burden was large.

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

[0005]

[Means for Solving the Problems]

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

【Example】

 Next, embodiments of the present invention will 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. The ratchet wrench 20 is provided with sockets 21 and 22 for fitting and turning into the class 6 of the suspension band, and the rotation direction of the sockets 21 and 22 can be changed by the ratchet mechanism.

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. It is composed of 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 handle 30 and the handle 10 are formed so that the handle 10 is inclined by 15 °.

When using the spectacles of this embodiment, as shown in FIG. 4, after inserting the spectacles opening 31 into the bolt 5 portion of the suspension band 2, lower the spectacles part and fit it into the nut 4. , The nut 4 is turned to fix the suspension band 2 to the bolt 5.

Moreover, since the handle 10 is inclined about 15 ° to 30 ° with respect to the glasses 30, there is no fear that the socket 21 (or 22) of the ratchet wrench 20 or the hand holding the handle 10 will be rubbed against the ceiling or the wall. You 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, so less fatigue is required.

Further, even in continuous tightening work, even if the hands are released while the glasses 30 are 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 eyeglasses 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 nuts are 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, the continuous tightening work can be carried out efficiently, and the risk of the tool coming off the high place and falling down can be greatly reduced.

[0011]

[Effect of the device]

 As described in detail above, according to the present invention, the ratchet wrench and the glasses are integrally formed at both ends of the common handle, so that pipe mounting can be performed with only one tool in the air conditioning work and the inner surface of the glasses can be installed. By forming an uneven surface that fits the outer shape of the nut, it is easy to fit the eyeglass part to the nut, and the tool does not drop even if you release your hand during work, so work at height is not dangerous And, there is an effect that it can be done efficiently. In addition, by forming the eyeglasses and the handle at an angle, it is possible to tighten the nuts on the ceiling or wall surface without difficulty.
