The box fixing device according to claim 5, wherein the box fixing device is formed.

  The box fixing device according to any one of claims 5 to 8, wherein the means adopted by the invention according to claim 9 is characterized in that the box body is formed with through holes in the bottom wall and the side wall, respectively. It is what.

  According to the bolt body fixture according to claim 1, the attachment portion can be easily engaged and fixed to the bolt body only by plastic deformation so that the proximity portion at the tip of the opening is relatively close. On the other hand, since the screwing portion can be easily fixed to the through hole formed in the arrangement body, the arrangement body can be easily fixed to the bolt body.

  According to the fixing device for the bolt body according to claim 2, since the screwing portion is made of the tapping screw, the fixing tool can be attached only by forcibly screwing the screwing portion into the through hole formed in the arrangement body. It can be fixed to the arrangement body.

  According to the bolt body fixture of claim 3, the shaft center of the screwing portion and the rotation axis of the mounting portion when the screwing portion is attached to the arrangement body are formed obliquely. When attaching to the bolt body, the attachment portion is attached obliquely with respect to the axial direction of the bolt body. Therefore, the attachment body is attached at an angle twisted with respect to the bolt body, and the attachment portion can be prevented from rotating on the outer periphery of the bolt body of the bolt body.

  According to the bolt body fixture according to claim 4, since the anti-rotation metal fitting that prevents the opening of the proximity portion at the tip of the opening and the rotation of the outer periphery of the bolt body is provided, While being able to fix to a bolt body, it can prevent coming off from a bolt body.

  According to the box fixing device according to claim 5, the box fixing device which can be easily attached to the bolt body by bringing the proximity portion provided at the opening tip of the attachment portion into proximity with the bolt body inserted. It can be.

  According to the box fixing device of the sixth aspect, since the screwing portion is made of the tapping screw, the fixing tool can be easily attached to the box body.

  According to the box fixing device of the seventh aspect, since at least two fixing tools are provided, it can be more stably fixed to the bolt body. In addition to strengthening the fixing force by simply having two fixing locations, it is extremely difficult to insert two fixing devices in parallel when the fixing device is actually attached to the box fixing device. It is rare and in practice will be mounted in a somewhat twisted arrangement. For this reason, the pitch of the engagement screw surfaces of the attachment portion is shifted from each other, and this shift makes it difficult to rotate the outer periphery of the bolt body as compared with one case.

  Furthermore, if there is only one fixture, there is a possibility that the screw will rotate around the threaded portion. However, by providing two fixtures, it is possible to completely prevent rotation in this direction. become.

  According to the box fixing device of claim 8, since the axis of the screw part and the rotation axis of the attachment part when the screw part is attached to the arrangement body are provided non-parallel, the bolt body The attachment portion attached to the head is attached to be inclined with respect to the axial direction. Therefore, it is possible to prevent the box fixing device from rotating around the outer periphery of the bolt body.

  According to the box fixing device of the ninth aspect, the fixing tool can be attached to either the bottom wall or the side wall of the box, and the fixing place for the bolt body can be appropriately selected.

  The bolt body fixing device of the present invention includes an attachment portion and a screw portion, and the attachment portion has a function of fixing to a bolt body such as a suspension bolt, and the screw portion is a cable rack or It has a function of fixing to an arrangement body such as a wiring box. That is, the bolt body fixture of the present invention has a function as an intermediate fixture for fixing the bolt body and the arrangement body to each other.

  The attachment part has a substantially U-shaped opening into which the bolt body can be inserted from the side, a part formed in a semicircular shape so as to be in close contact with the outer periphery of the bolt body, and the bolt body from both sides thereof It is formed from a linear part that deforms after inserting the bolt and fixes a bolt body that is an adherend, and a tip that extends from the part on the straight line to both sides. The semi-circular portion is not deformed because it is in close contact with the outer periphery of the bolt body. On the other hand, the straight portion and the tip portion are formed so as to be plastically deformable so as to be relatively close to each other so that the bolt body can be disposed and fixed in the opening portion, and form a proximity portion. Further, the inner surface of the opening is provided with an engaging screw surface that engages with the outer surface screw surface of the bolt body, and is prevented from moving in the axial direction after being fixed inside the opening. Since the attachment part is finally plastically deformed and maintained in a state where the bolt body is inserted therein, a material that is easy to plastically deform and can maintain the form after plastic deformation is used. It is done. Preferably, it is good to produce with steel materials.

  On the other hand, the screwed portion is provided with a so-called bolt or screw on the side opposite to the opening of the mounting portion, that is, a portion formed in a semicircular shape and not subjected to plastic deformation. Even if the proximity portion is plastically deformed by being provided at this portion, the screwed portion is not affected and the relative position of the circularly formed portion to the screwed portion does not change.

This screwing portion is fixed to an arrangement body such as a cable rack or a wiring box, and is attached using a through hole provided in advance in the arrangement body. When the screwing portion is a bolt type, the screw is passed through a through hole larger than the thickness of the bolt, and is fixed by tightening with a nut from the back or sandwiching with a nut (see FIG. 4). When the threaded portion is a tapered screw type, it is used as a tapping screw, and is screwed into the through hole while being fixed by itself (see FIG. 13). At this time, according to the bolt body fixing tool of the present invention, the attachment portion provided on the side opposite to the screw attachment portion functions like a so-called butterfly bolt, so that it can be easily screwed in with a finger. Note that the axis of the screwed portion and the rotation axis of the attaching portion when the screwed portion is attached to the arrangement body may be formed obliquely. That is, as shown in FIG. 14, the shaft center β of the screwed portion may be shifted by θ relative to the rotational axis α of the mounting portion. If inclined in this way, the external thread surface of each bolt body and the engaging thread surface of the mounting portion of the fixture to the plurality of bolt bodies attached are twisted and attached (to the opening, This is because the bolt body is attached in an inclined state (see FIG. 15), and the outer periphery of the bolt body can be prevented from rotating.

  The number of bolt bodies attached to the arrangement body is not limited, but two or more bolt bodies may be attached. The attachment position may be selected by appropriately selecting through holes provided in advance on the bottom and side surfaces of the arrangement body according to the position where the arrangement body is finally arranged with respect to the bolt body. The arrangement body to which the fixture for the bolt body is thus attached is attached to the bolt body on the attachment portion side. The method of plastically deforming the proximity portion of the attachment portion is not limited, but the proximity portion can be easily plastically deformed by using a pinching tool T such as pliers (see FIG. 5). By this plastic deformation, the outer surface screw surface of the bolt body and the engaging screw surface of the attachment portion are attached to the bolt body.

Further, it is preferable to provide a rotation stopper so that the attachment portion does not rotate around the bolt body. The anti-rotation bracket is for further tightening the adjacent proximity portion and fixing the proximity portion to the bolt body. That is, even if the proximity portion is tightened with pliers or the like, a slight gap is formed between the proximity portions. Therefore, it is preferable that the adjacent portions are further tightened and fixed with a rotation stopper metal so that the attachment portion does not rotate around the bolt body. The anti-rotation metal fitting is formed with a groove that can be fitted in a state in which the proximity portions overlap each other, and the proximity portion can be tightened by fitting the proximity portion into the groove. More preferably, the groove is formed narrower as it comes closer to the base, and is formed so that the proximity portion can be tightened as it is fitted easily at the beginning.
Thus, the arrangement body is fixed to the bolt body via the fixture to the bolt body. Since the external thread surface of the bolt body and the engaging thread surface of the attachment portion are engaged with each other, the fixture to the bolt body according to the present invention is stably displaced to the bolt body without being displaced in the axial direction of the bolt body. Fixed. In addition, according to the attachment portion of the present invention, the opening portion is plastically deformed after being disposed from the side of the outer surface of the bolt body, and therefore it is questionable that the opening portion is an intermediate portion when it is an end portion of the bolt body. Therefore, it is possible to attach the attachment body at an arbitrary position.

  The box fixing device of the present invention includes a box for fixing the fixture to the bolt body described above with the box for fixing the fixture to the wall surface by inserting the fixture from the opening with the opening facing the wall surface. The combination is the same as described above.

  Next, examples will be described with reference to the drawings. FIG. 1 is a front view of a fixture 100 to a bolt body 200 according to the first embodiment. FIG. 2 is a side view of the fixture 100 attached to the bolt body as viewed from the attachment portion side. FIG. 3 is a perspective view of the fixture 100 to the bolt body.

The bolt body fixture 100 in this embodiment includes an attachment portion 10 and a screw portion 20.
The attachment portion 10 is substantially U-shaped and has a cross section with a widened tip. The distal end of the attachment portion 10 with the distal end widened forms a proximity portion 13, and an engagement screw surface 12 that can be engaged with an outer surface screw of the bolt body 200 that is an attachment body is provided inside the opening 10 a. ing.

  On the other hand, the threaded portion 20 is provided on the opposite side of the opening 10a of the mounting portion 10 and has a groove threaded therein. As shown in FIG. 4, the fixture 100 to the bolt body manufactured in this manner is a box as an arrangement body in which the opening faces the wall surface and the instruments are inserted from the opening to fix the instruments to the wall surface. The screwing portion 20 is inserted into a through hole provided in the main body 300, and is fixed by tightening with a nut from the opposite side, thereby creating a box fixing device. The nut body may be inserted into the box body.

  Then, as shown in FIG. 5, the other attachment portion 10 abuts the engagement screw surface 12 from the side against the outer surface of the bolt body 200 that is the attachment object, and then the proximity portion 13. Is gripped by a pinching tool T such as pliers, and the proximity portion 13 is plastically deformed and fixed by being relatively close.

  Furthermore, the rotation stopper 40 is attached so that the fixture 100 to the bolt body does not rotate around the bolt body 200. As shown in FIG. 6, the anti-rotation bracket 40 is for sandwiching adjacent portions and fastening and fixing a gap d between the adjacent portions. The rotation stopper has a groove 40a that can sandwich the proximity portion. The groove 40a has a wide tip and a narrow base, and can be easily fitted by hand at first. Finally, as shown in FIGS. By forcibly fitting, the gap of the proximity portion 13 can be closed as shown in FIG. 9 and can be securely fixed to the fixing tool 100 to the bolt.

FIG. 10 shows a state where the bolt body 200 is fixed in this manner. In FIG. 10, it is fixed to the bolt body 200 arranged between the lightweight steel frames,
Two fasteners 100 to the bolt body are attached to the through holes 310 on the side wall of the box body 300 and fixed to the bolt body 200. The mounting position of the fixing tool 100 to the bolt body is not particularly limited. For example, the through hole 310 provided on the upper side wall of the box main body 300 shown in FIG. Moreover, the through hole 310 on the opening side or the through hole 310 on the bottom surface side may be used. However, it is preferably provided at a position that does not interfere with the knockout hole, that is, between the knockout holes at the center in the case of the bottom surface, and on the opening side or the bottom surface portion side so as to avoid the knockout hole in the case of the side surface. As shown in FIG. 11, the fastener 100 to the bolt body may be attached to the through hole 310 provided on the bottom surface of the box body 300 and fixed to the bolt body 200, and the attachment position of the fastener to these bolt bodies May be appropriately selected depending on the place where the box fixing device is attached. For example, when mounting in a narrow space such as a lightweight partition, the mounting method as shown in FIG. 10 is suitable, and when there is a relatively large space, the mounting method as shown in FIG. Is suitable. Needless to say, the bolts to be fixed may be arranged vertically such as suspension bolts. Further, the bolt body 300 protruding inside the box main body is covered with a cover on the front end of the bolt body 300 or the front end is not exposed to the inside in advance in order to prevent damage to components and electric wires arranged inside. In this way, a cylindrical bolt cover portion may be attached to the box body in advance so that the entire bolt is covered.

  FIG. 12 illustrates a fixture 101 for a bolt body according to the second embodiment. The fixing metal fitting 101 to the bolt body according to the second embodiment is different from the first embodiment in that the screwing portion 21 is a tapping screw. Other points are the same as in the first embodiment.

  If the fixing tool 101 to the bolt body of the second embodiment is used, it is possible to fix to the box body while forming a female screw in the through hole by forced screwing without using a nut when fixing to the box body 200. At this time, since the attachment portion functions as a part of the thumb screw, it can be easily forcibly screwed with bare hands.

  FIG. 14 shows a fastener 102 to a bolt body according to the third embodiment. The fixture 102 to the bolt body of the third embodiment is different from the first embodiment in that the direction of the axis 22 of the screwed portion 22 is inclined. That is, the axial center β of the screwing portion 22 and the rotational axis α of the attachment portion 10 when the screwing portion 22 is attached to the arrangement body 300 are shifted from each other by an angle θ and provided non-parallel. If the shaft centers are shifted in this way, two fasteners 102 to the bolt body 102 are attached as shown in FIG. 15 (in FIG. 15, the inclination of the attachment portion is emphasized from the fact). When the box fixing device attached to the box main body 300 is created, the attachment portions 10 are formed to be inclined by θ, and the directions of the engagement screw surfaces of the two attachment portions 10 are shifted and attached to the bolt body 200. Therefore, if the rotation around the bolt body is attempted, the direction of the screw surface is different, so that it interferes with the screw surface of the bolt body. Therefore, it is possible to prevent the box body from rotating around the bolt body without the rotation stopper.
