Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a wrench, and particularly to a wrench that is provided with a receiving member for liquid that flows out when a rotated object such as a bolt or a lid is loosened or tightened. Regarding.

[Prior Art] Flushing is performed for piping in various devices, equipment such as pumps, and mechanical seals for various equipment to clean rust, deposits, dirt, etc. inside the pipes and equipment passages. usually,
A strainer is attached to the flushing line, and this strainer collects rust, deposits, dirt, etc., and removes them by cleaning the strainer.

In this case, in order to take out the filtration part of the strainer, it is necessary to remove the lid of the filtration part, but conventionally,
This lid was removed using a common wrench.

[Problems to be Solved] As mentioned above, when removing the strainer lid using a general wrench, the liquid and dirt accumulated inside the strainer will flow out, damaging the worker's hands and There was a problem with contamination on equipment or floors.

In this case, it is possible to place a container such as a bucket below the strainer, but depending on the position where the strainer is installed, it may not be possible to place the container below it, or even if it is possible to place a container below it. However, it was not possible to prevent the workers' hands from being soiled by liquid flowing through the wrench handle. This problem is especially serious when the liquid that flows out is oil or something that has an adverse effect on the human body.

The present invention has been developed in view of the above-mentioned problems, and when the lid of a strainer, etc. is removed with a wrench, the liquid and dirt flowing out from inside the strainer, etc. are removed from the engaging part. The purpose of the present invention is to provide a wrench that is received by a receiving member provided on the outer periphery so as not to stain the hands of workers, equipment, or the floor surface, and which can also be used as a normal wrench without a receiving member. .

[Means for solving problems and effects] In order to achieve the above object, the wrench of the present invention is provided with a removably container-shaped receiving member on the outer periphery of the engaging part, and this receiving member is formed higher than the engaging part. This is the configuration.

As a result, the receiving member reliably receives and stores the liquid that flows out, and the liquid can be disposed of all together after using the wrench. Furthermore, by removing the receiving member, it can be used as a regular wrench.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

FIG. 1 is an overall perspective view with a part of the main part of the first embodiment cut away, and FIG. 2 is a sectional view of the main part of the first embodiment.

In these drawings, reference numeral 1 designates an engaging portion, which is a polygonal box portion 2 that engages with a rotated body such as a nut, a bolt head, or a nut-shaped lid.
This engaging portion 1 has a shaft 3 at its lower end, and engages with a ratchet portion 5 at the tip of a ratchet handle 4. As a result, this wrench is able to hold the ratchet handle 4 while keeping the engaging portion 1 engaged with the rotated object.
By reciprocating, the rotated body can be tightened or loosened.

Reference numeral 6 denotes a receiving member, which is attached to the outer periphery of the engaging portion 1. That is, the receiving member 6 has a container shape as a whole, and a screw hole 6a is provided at the bottom to be screwed into the screw 1a formed on the outer periphery of the lower end of the engaging portion 1. Therefore, depending on the use of the wrench, the receiving member 6 is used by being screwed onto the engaging portion 1 only when it is required.

In this case, by tapering the outer periphery of the lower end of the engaging part 1 (see Fig. 4) or by providing a stopper 1b at the lowest end of the engaging part 1 (see Fig. 5), the attachment of the receiving member 6 can be ensured. can be done. Further, in order to reliably prevent liquid from leaking from the threaded portions 1a, 6a, etc., an O-ring 1c or the like may be used (see FIG. 5).

Further, the receiving member 6 is formed higher than the engaging portion 1, and when the engaging portion 1 is engaged with the rotating body, the receiving member 6 completely covers the non-rotating body. Therefore, using this wrench, for example, as shown in FIG.
When the lid 11 of the strainer 10 is loosened and removed, the strainer 10 is completely covered from below, so that the liquid leaking from the strainer can be reliably received and collected by the receiving member 6. can.

Incidentally, once all the liquid, filth, etc. have flowed out from the strainer 10 into the receiving member 6, the liquid, filth, etc. accumulated in the receiving member 6 are disposed of in a container such as a bucket. This prevents liquid, dirt, etc. that have flowed out from inside the strainer 10 from spilling into the surrounding area and from staining the hands of workers.

In addition to the above-described embodiments, the wrench of the present invention includes, for example, the following modifications.

The middle part of the receiving member 6 is made thin so that the liquid etc. accumulated in the receiving member 6 does not spill out during operation (see Fig. 6). or,
The opening of the receiving member 6 is enlarged to make it easier to receive the liquid etc. that flows out (Fig. 4,
(See Figure 5). Also, the diameter of the receiving member 6 is increased or the depth thereof is increased to increase the volume so that a large amount of liquid or the like can be stored therein. Furthermore, these can be combined as appropriate.

As a means for attaching and detaching the receiving member 6 to and from the engaging portion 1, an attachment/detachment means other than screws and screw holes is used.

The engaging part 1 is a rod-shaped wrench, and this engaging part 1
A receiving member 6 as described above is provided on the outer periphery (see FIG. 7). In this case, in order to prevent interference between the rotating body and the receiving member 6, it is desirable to make the diameter of the receiving member 6 somewhat larger.

These receiving members are applied to wrenches other than ratchet type wrenches.

According to the wrench of this embodiment configured in this way, when cleaning the strainer 10 attached to a flushing line or the like, the liquid that flows out when loosening and removing the lid 11 of the strainer 10 is removed. Dirt, etc. can be reliably received and collected by the receiving member 6 provided on the outer periphery of the engaging part 1, so that liquids, filth, etc. can be deposited on equipment around the strainer, on the floor, or on the hands of workers. It will not contaminate etc.

The wrench of the present invention can be used in a variety of situations, such as opening and closing the lids of various strainers, as well as opening and closing the stoppers of liquid containers.

[Effects of the invention] As described above, according to the wrench of the invention, the liquid etc. that flow out when the rotated body is loosened or tightened can be absorbed by the receiving member formed higher than the engagement part. Since it can be reliably received and collected, the spilled liquid does not stain the surrounding area or the workers' hands.

In addition, since the receiving member is removable, it is possible to use a receiving member of the optimal shape depending on the place where the wrench is used, and when there is no risk of liquid leaking, the receiving member can be removed and used as a regular wrench. It can also be used as
