Description

The present invention relates to a clamp for pipes holding.

  When two or more members made of a plate material are connected and fastened by screws, bolts may be inserted into communication holes provided in these members and screwed to nuts to be fastened. For example, in order to lock wires such as orchard parent lines, vine invitation lines, wind and bird net suspension lines, and bird protection lines to strut pipes and construction pipes, For example, a pipe holding clamp that clamps and holds a shaped pipe is back-to-back and connected with a bolt and a nut. In such a case, for example, when the bolt fastening operation is performed manually, the bolt is inserted into two members (in this case, a tensioner and a clamp for holding the pipe), and then the nut is pressed while holding the nut with a finger of the hand. The bolt fastening operation is performed by rotating and screwing or by rotating the nut while screwing the bolt head with fingers. When a plurality of members, for example, an operator manually connects and tightens the wire tensioner and the pipe holding clamp as described above, each member is directed in a predetermined direction, The bolt fastening operation is performed while pressing each member by hand so that the direction does not deviate, and supporting the bolt head and nut with fingers as described above.

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

  The first member according to the present invention is a pipe holding clamp, and the second member can be applied to a pipe holding clamp, a wire drawing device, various brackets, and the like. In this embodiment, the first member 3 is a pipe. A holding clamp 25 is used, and the second member 5 is a tensioner 30.

  Further, in this embodiment, a wire tensioner 30 (second member 5, hereinafter omitted) for winding and locking wires such as an orchard parent line, a vine invitation line, a wind-proof / bird-proof net hanging line, a bird-proof line, etc. ) Is connected to a pipe holding clamp 25 (first member 3, omitted hereinafter) that holds and fixes the round pipe 15 such as a support pipe, and the pipe holding the round pipe 15 is fastened and fixed. The clamp 25 and the wire tensioner 30 are back-to-back, and the pipe holding clamp 25 and the wire tensioner 30 are connected to each other using the hexagonal bolt 1 and the hexagonal nut 6. is there.

  Specifically, the pipe holding clamp 25 is a fastening opening / closing body in which a pipe holding edge 18 for holding the pipe 15 is formed at the base end portion of the base body 17 formed at the inner edge, and a pipe holding edge 18 is formed at the inner edge. The base end of 19 is pivotally attached, and a fastening opening / closing body 19 is provided so as to be openable and closable with respect to the base body 17. The pipe 15 is connected by screwing the fastening bolt 20 and the pipe 15 is clamped and held by the pipe holding edges 16 and 18, and the pipe holding clamp 25 and the wire tensioner 30 are back to back. An insertion hole 2 is provided in the base body 17 of the pipe holding clamp 25 so that it can be connected to the pipe.

  In addition, the wire tensioner 30 is provided with a rotating portion 33 on a U-shaped plate material 31 and a ratchet mechanism 32 biased by a spring 34 on the rotating portion 33, so that a wire suitable for the above-described purpose can be wound. The wire tensioner 30 is configured to be wound on the moving portion 33, and further, the insertion wire 4 is formed in the wire tensioner 30 so that the wire tensioner 30 can be connected back to back with the base 17 portion of the pipe holding clamp 25. Provided.

  Further, the pipe holding clamp 25 and the wire tensioner 4 superimpose the base 17 portion of the pipe holding clamp 25 and the wire tensioner 30 in a back-to-back state, and the bolt 1 is attached to the base 17. It is configured to have a member connecting structure that is inserted through the provided insertion hole 2 and the insertion hole 4 provided in the wire tensioner 30 and is connected by the bolt 1 and the nut 6 screwed to the bolt 1. Yes.

  Specifically, this member connection structure includes a locking plate 7 provided around the insertion hole 2 through which the shaft portion 12 of the bolt 1 is inserted into the base body 17 of the pipe holding clamp 25, and the locking plate 7 Are formed around the insertion hole 4 of the tensioner 30 and formed so as to be able to be fitted into the positioning fitting hole 8. Part 9.

  More specifically, the locking plate 7 is formed around the insertion hole 2 provided in the base body 17 of the pipe holding clamp 25 and is cut out at a right angle by cutting out the periphery of the insertion hole 2 in a U shape. The bolts are formed by sandwiching the side face 11 of the head 10 having the hexagonal shape of the bolt 1 with the pair of locking plates 7 provided at two opposing positions around the insertion hole 2. 1 is configured to be non-rotatable.

  Further, the positioning fitting holes 8 are formed at two places at the same time when the locking plate 7 is formed by cutting out around the insertion hole 2 in a U-shape and standing up at a substantially right angle. Each is configured to be a square window-like through hole.

  Further, the four convex portions 9 are provided at equal intervals around the insertion hole 4 of the wire tensioner 30 provided so that the shaft portion 12 of the bolt 1 is inserted, and the four convex portions 9 are provided. The base 17, that is, the pipe-holding clamp 25, is formed by fitting the fitting positioning positioning holes 8 provided in the base 17 of the pipe-holding clamp 25 into the two convex portions 9 facing each other. The connecting direction with the wire tensioner 30 can be determined.

  Therefore, the base 17 of the pipe holding clamp 25 and the wire tensioner 30 are superposed back to back, and the positioning fitting hole 8 provided in the base 17 and the wire tensioner 30 provided with the wire When the bolt 1 is inserted from the insertion hole 2 of the base body 17 into the insertion hole 4 of the wire tensioner 30 by fitting the convex portion 9, the pair of locking plates 7 are connected to the heads of the bolts 1. The bolt 1 can be locked and locked by sandwiching the side surface 11 of 10 from both sides. Therefore, even if the nut 6 is rotated and screwed to the bolt 1, the bolt 1 is locked. Therefore, if the nut 6 is rotated without supporting the head portion 10 of the bolt 1 by hand, the bolt 1 and the nut 6 can be screwed together. Therefore, the base 17 and the wire tensioner 30 can be quickly connected. In addition, the pipe holding clamp 25 and the wire tensioner 30 can be connected in a predetermined direction. It can be connected in an oriented state.

  In addition, as described above, around the insertion hole 4 of the wire tensioner 30, four protrusions 9 that can be fitted into the positioning fitting holes 8 are provided at equal intervals, so that the base body 17 is provided. When the convex portion 9 is fitted into the positioning fitting hole 8, the connecting direction of the base body 17 and the wire drawing device 30 can be selected from two orthogonal directions. This convex portion 9 is formed by punching (for example, half punching) and denting the periphery of the insertion hole 4 on one surface of the plate 31 formed in the U-shape, The other surface of the plate material 31 is protruded and formed into a convex shape. As a result, since the convex portion 9 has a comparatively gentle cross-sectional shape, the convex portion 9 is not completely locked when the base 17 and the wire tensioner 30 are fitted, and the base 17 In the state where the wire tensioner 30 and the wire tensioner 30 are temporarily fixed, if a slight force is applied to rotate, the orientation can be changed over the fitting portion by the convex portion 9, and the position in the orientation direction can be changed. It can be locked with little deviation.

  If the width of the base body 17 is made narrow so that the head 10 of the bolt 1 can be prevented from rotating by the side wall of the base body 17, the locking plate 7 can be made unnecessary. In this case, the positioning fitting hole 8 is not formed, so that it is necessary to provide the positioning fitting hole 8 separately, and the shape of the base body 17 is limited. Therefore, when the locking plate 7 is formed by cutting and raising the base 17 as described above, the positioning fitting hole 8 can be formed simultaneously, which is not only convenient for manufacturing, but also makes the width of the base dependent on the shape of the bolt. This also increases design freedom.

  When attaching the pipe holding clamp 25 and the wire tensioner 30 connected back to back to the pipe 15 as described above, for example, the fastening opening / closing body 19 is rotated with respect to the base body 17 to rotate the base body. The pipe 15 is held by the pipe holding edge 16 of the pipe 17 and the pipe holding edge 18 of the fastening opening / closing body 19, and the fastening bolt 20 is inserted into the fastening opening / closing body 19 in this state. When the rotating body 21 provided on the head is tightened and rotated, the head 22 of the tightening bolt 20 is engaged with the opening / closing tip of the tightening opening / closing body 19, and the opening / closing tip of the tightening opening / closing body 19 and the base body 17 The pipe 15 is clamped and held by the base body 17 and the clamp opening / closing body 19. After attaching the wire tensioner 30 to the pipe 15 in this way, if the wire is wound around the rotation part 33 of the wire tensioner 30 and the ratchet mechanism 32 is rotated using a crank handle or the like, the orchard can be pulled. Parent lines, vine invitation lines, wind and bird net suspension lines, bird lines, etc. can be provided.

  After attaching the wire tensioner 30 to the pipe 15 in this way, if the connection between the wire tensioner 30 and the pipe holding clamp 25 is loosened, the wire tensioner 30 and the pipe holding clamp 25 The bolt 1 and the nut 6 that are connected to each other are refastened. According to the present invention, since the head 10 is prevented from rotating by the locking plate 7, the nut 6 is rotated. When re-fastening, the bolt 1 can be re-fastened without turning the bolt 1 together with the turning of the nut 6.

  As described above, according to the present embodiment, when the bolt holding clamp 25 and the wire tensioner 30 are bolted back to back, the bolt 1 is prevented from rotating, so the head of the bolt 1 is supported by the fingers of the hand to prevent rotation. In addition, when connecting each member, that is, the pipe holding clamp 25 and the wire tensioner 30, it can be held in a position to be fitted even in a temporarily fixed state, and is also fitted when bolted. Since the deviation from the position is reduced as much as possible, the fastening operation can be easily and efficiently performed, and the locking plate and the positioning fitting hole can be formed at the same time, contributing to the simplification of the manufacturing process. It will be possible.

  The present invention is not limited to the present embodiment, and the specific configuration of each component can be designed as appropriate.
