  Embodiments of the present invention that are considered suitable (how to carry out the invention) will be briefly described with reference to the drawings, illustrating the operation of the present invention.

  For example, if the large-diameter head-tightening bolt 10 is temporarily fixed to the threaded portion 11 of the rotating body 7 in advance, each of the products of the present invention is large-diameter when the pipe 1 is held and fixed. There is no trouble of screwing the fastening bolt 10 and this fastening holding operation is easily performed.

  The fastening opening / closing body 5 is rotated with respect to the base body 3, and the pipe 1 is held by the pipe holding edge 2 of the base body 3 and the pipe holding edge 4 of the fastening opening / closing body 5. When the large-diameter head-tightening bolt 10 inserted into the notch 8 is tightened and rotated with respect to the screwed portion 11 of the rotating body 7 provided at the tip of the base 3, the large-diameter head-tightening bolt 10 has a large diameter. The head 12 is locked to the locking notch 8 of the fastening opening / closing body 5, and the opening / closing tip of the fastening opening / closing body 5 and the tip of the base 3 are connected via the fastening holding mechanism 6. Then, the pipe 1 is clamped and fixed by the base 3 and the clamp opening / closing body 5.

  The rotating body 7 is rotatable with respect to the tip end portion of the base 3, and the large-diameter head 12 of the large-diameter head-tightening bolt 10 screwed to the screwing portion 11 by rotating the rotating body 7. The locking position to the locking notch 8 can be changed according to the diameter of the pipe 1 to be held and fixed. That is, it can be held and fixed corresponding to pipes 1 having different diameters.

  Therefore, like the conventional product, the pipe 1 can be held and fixed by a simple screwing operation, and can also be used for the pipe 1 having a different diameter.

  Further, in the present invention, when the pipe 1 is held and fixed, the large-diameter head-tightening bolt 10 is screwed into the screwing portion 11 of the rotating body 7 provided at the tip of the base 3 and is screwed into the rotating body 7. Therefore, the tip of the large-diameter head-tightening bolt 10 is not exposed to the outside, and the large-diameter head 12 of the large-diameter head-tightening bolt 10 is connected to the locking notch 8 at the tip of the tightening opening / closing body 5. It will be exposed to the outside.

  That is, it is tightened from the nut engaged with the engaging portion (corresponding to the locking notch portion of the present invention) of the opening / closing tip of the tightening holding body (corresponding to the tightening opening / closing body of the present invention) as in the conventional product. The tip of the attached bolt does not protrude outward, but according to the present invention, since the large-diameter head 12 protrudes only slightly outside the locking notch 8, the degree of protrusion is the conventional product. It is extremely small compared to other tightening bolts, and the sharp thread of the large-diameter head tightening bolt 10 is not exposed, so that an operator may touch or hit it without using a cover. Prevented as much as possible.

  The clamping bolt 10 with a large diameter head is not temporarily fixed to the screwed portion 11 of the rotating body 7, and the pipe 1 is held by the base 3 and the fastening opening / closing body 5, and then the locking notch 8 is formed. The large-diameter head-tightening bolt 10 may be inserted, and the large-diameter head-tightening bolt 10 may be screwed into the screwing portion 11 of the rotating body 7 to be tightened and rotated.

  Further, for example, if the screwing portion 11 is configured by providing the rotating body 7 with a screw hole 13 through which the large-diameter head-tightening bolt 10 is threadably penetrated, the rotating body 7 is tightened with a large-diameter head. The screwing part 11 to which the bolt 10 is screwed can be easily designed and realized, and the screw hole 13 penetrates, so that the tightening screwing range of the large-diameter head-tightening bolt 10 can be set large. As a result, it is possible to employ the long-diameter head-clamping bolt 10 having a long length, so that it is possible to easily realize the expansion of the corresponding width to the pipe 1 having a different diameter.

  Further, for example, if the screw hole 13 constituting the screw part 11 is configured by providing the nut 16 in the rotating body 7, the screw hole 13 ( The screwing part 11) can be designed easily with respect to the rotating body 7.

  Further, for example, the rotating body 7 is provided with a nut housing space 17 for housing the nut 16, and the nut 16 is fixed or prevented from rotating in the nut housing space 17 of the rotating body 7. If the insertion hole 14 communicating with the screw hole 13 is provided at the distal end portion 9 of the rotating body 7, the nut 16 is provided at the distal end portion 9 of the rotating body 7, and the large-diameter head is tightened in the rotating body 7. It is possible to easily design and realize a structure in which the bolt 10 is not screwed in and is not exposed to the outside, and the nut 16 in the fixed or non-rotating state is locked by hand when the large-diameter head tightening bolt 10 is tightened and rotated. Since there is no need to do this, the tightening operation can be performed easily.

  Further, for example, the rotating body 7 has a configuration in which a plate material is formed in a U-shape and has a nut accommodating space 17 on the inside, and the base end portion of the rotating body 7 is freely rotatable at the distal end portion of the base 3. The nut 16 is disposed in the nut receiving space 17 of the rotating body 7, and the outer peripheral portion of the nut 16 is locked in the locking hole 20 provided in the side wall portion of the rotating body 7 so as to prevent rotation. If the insertion hole 14 is housed and the insertion hole 14 is provided at the tip of the rotating body 7, the rotating body 7 having the nut housing space 17 on the inside can be easily designed and realized. By simply bending the plate so that the outer periphery of the nut 16 fits into the locking hole 20 provided in the nut 16, the nut 16 is engaged with the nut receiving space 17 in the rotating body 7 in a non-rotating state. Since it is stopped, the nut 16 can be prevented from falling off and prevented from rotating simultaneously with a simple configuration. Become more practical configuration that can.

  Further, for example, the large-diameter head-tightening bolt 10 has a large-diameter rotating operation head that is tightened and rotated with a rotating tool on the upper surface portion of the screw portion 18 of the large-diameter head-tightening bolt 10. If the large head 12 is provided, the large-diameter head-tightening bolt 10 that can be easily tightened and rotated using a rotating tool can be easily designed and realized.

  Further, for example, if the large-diameter head 12 is a hexagonal nut-shaped head, the pipe 1 is clamped and held using a general-purpose rotating tool capable of rotating an existing hexagonal bolt or hexagonal nut. Work can be done easily.

  A first embodiment of the present invention will be described with reference to FIGS.

  This embodiment is applied to a small pipe holding clamp 30 for fastening and holding a relatively small round frame pipe 1 for constructing a greenhouse, and holding the pipe 1 The base end portion of the fastening opening / closing body 5 formed with the pipe holding edge 4 at the inner edge is pivotally attached to the base end portion of the base body 3 having the edge 2 as the inner edge, and the fastening opening / closing body 5 is attached to the base body 3. A tightening holding mechanism that is provided so as to be openable and closable, and that connects the opening / closing tip of the fastening opening / closing body 5 and the tip of the base 3 to clamp and hold the pipe 1 by the pipe holding edges 2 and 4. 6 is provided.

  In detail, the base 3 of the present embodiment is formed of a U-shaped cross-section in which both side edges in the longitudinal direction of the belt-shaped metal plate are bent at right angles, and the bent leading edges of the right-angle bent portions on both sides are formed. The arc-shaped pipe holding edge 2 is used.

  Further, the fastening opening / closing body 5 of the present embodiment is also formed of a U-shaped cross-sectional body in which both side edges in the longitudinal direction of the belt-like metal plate are bent at right angles in the same manner as the base 3, The bent leading edge of the portion is the arc-shaped pipe holding edge 4.

  The pivot structure of the base body 3 and the fastening opening / closing body 5 is formed by superposing the bent portions on both sides of the base end portion of the base body 3 and the bent portions on both sides of the base end portion of the fastening opening / closing body 5. By tightening the shaft pin 15 through the overlapped portion and crimping, the fastening opening / closing body 5 can be opened and closed with respect to the base body 3 with the shaft pin 15 as a fulcrum (pivot shaft).

  The tightening holding mechanism 6 of the present embodiment is provided with a screwing portion 11 on which a large-diameter head-tightening bolt 10 is screwed to a rotating body 7 that is rotatably provided at a tip portion of the base 3. A locking notch 8 for inserting the large-diameter head-tightening bolt 10 is provided at the opening / closing tip of the opening / closing body 5, and the large-diameter head-tightening bolt 10 screwed to the screwing portion 11 is tightened and rotated. By doing so, the large-diameter head 12 of the large-diameter head-tightening bolt 10 is configured to be able to hold the pipe 1 by being engaged with the locking notch 8 of the tightening opening / closing body 5. Yes.

  Specifically, as shown in FIGS. 1 and 9, the rotating body 7 is configured such that a plate material is bent into a U shape and has a nut housing space 17 inside between the side wall portions on both sides. 17 is provided with a nut 16 in a non-rotating state, and an insertion hole 14 communicating with the screw hole 13 of the nut 16 is formed through the intermediate plate portion of the rotating body 7 so that the screw hole 13 of the nut 16 is inserted into the insertion hole. The screw portion 11 through which the large-diameter head-tightening bolt 10 is threadably passed through 14 is provided.

  More specifically, rectangular locking holes 20 are formed in the side wall portions on both sides of the rotating body 7, and the plate member constituting the rotating body 7 is used as the nut 16 when bent into a U-shape. By locking the opposite corners of the hex nut 16 in the respective locking holes 20, the nut 16 is housed in a nut-locked state in the nut housing space 17 between the side wall parts on both sides.

  Therefore, by simply folding the plate material into a U-shape and locking the general-purpose hex nut 16 in the locking hole 20, the rotating body 7 including the screwed portion 11 is secured to the nut housing space 17 by rotating the nut 16. Thus, the rotating body 7 having the threaded portion 11 can be manufactured very simply and without cost, without the need for screw hole formation or welding.

  The rotating body 7 is attached to the distal end portion of the base body 3 with the intermediate plate portion in which the insertion hole 14 of the rotating body 7 is formed as the distal end portion 9 and the side wall portions on both sides as the proximal end portions. Both side wall portions are overlapped with bent portions on both sides of the tip of the base 3, and the mounting pin 22 is passed through the overlapped portion and fixed by caulking, thereby using the mounting pin 22 as a fulcrum (rotating shaft). The rotating body 7 is rotatably attached to the front end portion. Reference numeral 19 in the figure denotes a bearing hole 19 of the mounting pin 22 formed at the base end portion of the both side walls of the rotating body 7.

  Accordingly, when the screw portion 18 of the large-diameter head-tightening bolt 10 inserted into the locking notch portion 8 is screwed into this screwing portion 11 and deeply screwed (screw advancement) by a tightening operation, The distal end portion of the screw portion 18 advances from the penetrating screw hole 13 to the nut accommodating space 17 on the proximal end side from the nut 16 of the rotating body 7, and the distal end portion of the screw portion 18 projects outward. Instead, only the large-diameter head 12 of the large-diameter head-tightening bolt 10 protrudes slightly from the locking notch 8.

  Further, in this embodiment, the formation positions of the locking holes 20 on the side wall portions on both sides are set so that the screw holes 13 and the communication holes 14 of the nut 16 are in a communication state without leaving a gap. Thus, the large-diameter head-tightening bolt 10 inserted into the communication hole 14 can be immediately screwed into the screw hole 13 to improve the screwing operability.

  The large-diameter head-clamping bolt 10 of the present embodiment has a configuration in which a rotating operation head that can be tightened and rotated with a rotating tool is provided as the large-diameter head 12 on the upper surface of the screw portion 18. More specifically, a hexagon head bolt is employed.

  Further, the hexagonal large diameter head 12 of the large diameter head tightening bolt 10 employs a relatively thin pressure shape, and although not shown in detail, the upper peripheral edge thereof is rounded off. When tightened and locked to the notch 8 for locking, the structure is such that it does not protrude greatly to the outside and a person or object is not easily caught on the smooth upper peripheral surface (R surface).

  The large-diameter head-tightening bolt 10 is set so that the diameter of the large-diameter head 12 of the large-diameter head-tightening bolt 10 is larger than the width of the locking notch 8. 12 is configured so that it can be securely fastened and locked to the tip of the fastening opening / closing body 5 around the notch 8 for locking.

  Further, on the lower part of the large-diameter head 12, a flange 23 is provided that protrudes in a disk shape outward from the hexagonal circumferential surface of the large-diameter head 12, and the diameter is increased by the flange 23 having a larger diameter than the hexagonal circumferential surface. When the large head 12 is rotated and locked to the fastening opening / closing body 5 locking notch 8, the hexagonal peripheral surface of the large diameter head 12 is prevented from being caught by the locking notch 8. is doing. Therefore, when the large-diameter head-tightening bolt 10 is inserted into the locking notch portion 8 of the tightening opening / closing body 5, it is caught when the tightening rotation is performed on the screwed portion 11 using a rotating tool. Therefore, the rotation operation can be performed smoothly. Further, the presence of the flange 23 increases the area of engagement with the front end portion of the fastening opening / closing body 5 around the notch 8 for locking, so that the engagement of the large diameter head 12 with the notch 8 for locking is increased. Stability will be improved.

  In addition, the locking notch portion 8 of this embodiment for inserting the large-diameter head-tightening bolt 10 forms a flat intermediate plate portion at the front end portion of the tightening opening / closing body 5, and also the front end of the intermediate plate portion. It forms in the notch part 8 which the front end side notched so that it may have length toward the base end direction of the clamping opening / closing body 5 may open | release from an edge.

  Accordingly, for example, the large-diameter head-tightening bolt 10 temporarily screwed to the screwing portion 11 of the rotating body 7 is rotated from the open end portion of the locking notch 8. The fastening opening / closing body 5 and the turning body 7 can be fastened and fixed by tightening and turning the large-diameter head-tightening bolt 10 temporarily fixed in this state.
