Description

Technical Field

[0001] The present invention relates to a component for a flexible clamp that enables a single-pipe flexible clamp to be fixed at a desired angle within a range of 360 degrees.

Background Art

[0002] Single-pipe clamps are classified into fixed-type and flexible-type. The fixed-type clamp can only be fixed at an attachment angle of 90 degrees. The flexible-type clamp can be selected over 360 degrees, but cannot be fixed at a desired angle alone.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Commercially available flexible clamps cannot be fixed alone at a desired angle after holding and tightening a single pipe (except when three are used to form a triangle). Although it is possible to use multiple clamps, the workability is poor. Patent Document 1 discloses a flexible clamp that can fix the attachment angle. However, it requires the operation of tightening bolts and also requires processing of commercially available flexible clamps, and thus cannot be easily used. Based on the above, it is an object to enable fixing at an arbitrary angle of 360 degrees with good workability without processing commercially available flexible clamps. Furthermore, regarding 0 degrees - 90 degrees - 180 degrees, it is an object to achieve workability equal to or better than that of commercially available fixed-type clamps.

Means for Solving the Problems

[0005] The present invention solves the above problems by adding components with an extremely simple structure to existing commercially available adjustable clamps. The First Invention of the Present Invention A polygonal component for use with a commercially available adjustable clamp, wherein the polygonal component has a thickness slightly greater than that of the pipe receiver of the fixed piece of the press-side clamp, and is characterized in that a knurling process is applied to the contact surface with the base of the commercially available adjustable clamp. A component for an adjustable clamp. The Second Invention of the Present Invention A component for an adjustable clamp composed of at least a circular component and a polygonal component, wherein the circular component has a fan-shaped hole and a central hole, a knurling process is applied to the surface corresponding to the polygonal component, the polygonal component has a protrusion and a central hole, the protrusion is located at a position corresponding to the fan-shaped hole of the circular component, the circular component and the polygonal component are loosely connected by a connecting member through the central hole, and is higher than the bottom edge of the pipe receiver of the fixed piece of the commercially available adjustable clamp to be installed, and the protrusion of the polygonal component is characterized in that it circularly slides within the fan-shaped hole of the circular component. A component for an adjustable clamp. The Third Invention of the Present Invention A component for an adjustable clamp composed of at least a circular component and a polygonal component, characterized in that a circular base is provided on the polygonal component, and a protrusion is further provided on the circular base. A component for an adjustable clamp. The Fourth Invention of the Present Invention A component for an adjustable clamp composed of at least a circular component and a polygonal component, wherein the polygonal component has a plurality of steel balls, one of the steel balls is incorporated as a protrusion into the fan-shaped hole of the circular component, and the other steel balls are characterized in that they provide a margin for the circular component and the polygonal component to circularly slide. A component for an adjustable clamp.

Effects of the Invention

[0006] In the use of commercially available adjustable clamps, by attaching the components of the present invention, it can be fixed at any angle of 360 degrees. (When the protrusion corresponding to the fan-shaped hole hits the end point of the fan-shaped hole, 0 degrees, 90 degrees, and 180 degrees can be easily obtained without measurement.) There is no need to modify commercially available adjustable clamps. The workability is good, the work efficiency is improved, and the work by one person becomes easy.

Modes for Carrying Out the Invention

[0008] Next, examples of embodiments of the present invention will be described. (Circular part) Figure 1 The material of the part is preferably a steel plate. The diameter of the circular part is sized to fit inside the base of the commercially available adjustable clamp fixing piece. The width of the sector-shaped hole drawn with the radius from the center hole of the circular part is preferably the width through which the protrusion of the polygonal part can slide easily. Also, perform knurling on the contact surface with the polygonal part. The circular part is welded to the fixed piece base of the commercially available clamp.

[0009] (Polygonal part 4A) Figure 2 The material of the part is preferably a steel plate. The size of the polygonal part 4A is such that it can fit inside the fixed piece base of the commercially available clamp. In Figure 2, a circular base is provided by pressing or the like. The circular base is larger than the outer radius of the fan-shaped hole of the circular part, and it is desirable to perform knurling on the contact surface with the circular part and the contact surface with the pipe. (Hereinafter, the same applies to the polygonal parts 4B and 4C). The shape of the polygonal part is preferably a quadrilateral, pentagon, or hexagon. (Hereinafter, the same applies to the polygonal part 4B, polygonal part 4C, and polygonal part 4D). (Polygonal part 4B) Figure 3 The material of the part is preferably a steel plate. The size of the polygonal part 4B is such that it can fit inside the fixed piece base of the commercially available clamp. In Figure 3, a plurality of steel ball holding holes are provided. (Polygonal part 4C) Figure 4 The material of the part is preferably a steel plate. The size of the polygonal part 4C is such that it can fit inside the fixed piece base of the commercially available clamp. In Figure 4, a protrusion is provided. (Polygonal part 4D) Figure 5 The material of the part is preferably a steel plate. The size of the polygonal part 4D is such that it can fit inside the fixed piece base of the commercially available clamp. In Figure 5, it is higher than the pipe receiver of the commercially available clamp fixed piece. It is desirable to perform knurling on the contact surface with the pipe.

[0010] (Relationship between the polygonal part 4D and the commercially available clamp) The polygonal part 4D is not welded to the commercially available clamp and is placed inside the fixed piece base of the commercially available clamp.

[0011] (Integration of Circular Parts and Polygonal Parts 4A, 4B, 4C) In the case of the polygonal part 4A, the fan-shaped hole of the circular part is aligned with the circular base side of the polygonal part 4A, and the protrusions of the fan-shaped hole of the circular part and the circular base of the polygonal part 4A are matched. Then, they are connected by a connecting member through their respective central holes, forming a component for the universal clamp of the present invention. (Not shown in the figure) However, the circular part and the polygonal part 4A are connected with a margin so that they can slide. In the case of the polygonal part 4B, a plurality of steel balls or the like are sandwiched between the circular part and the polygonal part 4B, and they are connected by a connecting member through their respective central holes, forming a component for the universal clamp of the present invention. (Not shown in the figure) However, the circular part and the polygonal part 4B are connected with a margin so that they can slide. In the case of the polygonal part 4C, the fan-shaped hole of the circular part is matched with the protrusion of the polygonal part 4C, and they are connected by a connecting member through their respective central holes, forming a component for the universal clamp of the present invention. (Not shown in the figure) However, the circular part and the polygonal part 4C are connected with a margin so that they can slide. As the connecting member, bolts, nuts, rivets, etc. can also be used.

[0012] (Comparison Table of the Configuration of the Polygonal Part and the Circular Part of the Component for the Universal Clamp of the Present Invention) The configuration of the circular part and the polygonal part of the present invention is summarized in FIG. 12 as a comparison table.

[0013] (Integration of the Component for the Universal Clamp and a Commercially Available Universal Clamp) For a commercially available universal clamp, two clamps are connected at the base of their respective fixed pieces, enabling free rotation. However, the angle cannot be fixed. The connecting member of the commercially available universal clamp is annular. The circular part side of the component for the universal clamp of the present invention is applied against the inside of the base of the clamp fixed piece on the press side of the commercially available universal clamp. If the circular part and the clamp base on the opposite side of the press side of the commercially available universal clamp are joined together by welding, for example, the circular part and the opposite clamp of the commercially available universal clamp are integrated and rotate in the same way.

[0014] (Fixing the Angle of a Single Pipe) Hold a single-pipe in the holding part of a clamp equipped with the parts for a flexible clamp at a predetermined angle, and tighten the nut from the polygonal part side with the clamping part. When installing the parts for a flexible clamp, manufacture them slightly higher than the bottom edge of the single-pipe receiver of the fixed piece of a commercially available flexible clamp. When tightening the single-pipe with a tightening nut, the tightening pressure is transmitted to the circular part by pressing the polygonal part of the parts of the present invention against the single-pipe, and the circular part is fixed. Saying that the circular part is fixed means that the other clamp is fixed and the angle between the clamps is fixed.

Example

[0015] Hereinafter, examples will be described with reference to the accompanying drawings. The present invention is not limited to these examples. A hexagonal part 4D was manufactured from a steel plate. The hexagonal part 4D was manufactured to have a thickness slightly higher than that of the pipe receiver of the fixed piece of the press-side clamp of a commercially available flexible clamp, and knurling was performed on both sides. The hexagonal part 4D was placed inside the fixed piece on the press side of a commercially available flexible clamp. At that time, it is not welded to the commercially available flexible clamp.

Example

[0016] A circular part 1 with knurling on one side and a hexagonal part 4C with knurling on both sides were manufactured from a steel plate. The circular part 1 has a thickness of 3.2 mm, a diameter of 40 mm, a fan-shaped hole width of 4 mm, and a center hole diameter of 3.2 mm. The hexagonal part 4C has a thickness of 4.5 mm and a center hole diameter of 3.2 mm.

[0017] A part obtained by matching the fan-shaped hole of the circular part 1 and the protrusion of the hexagonal part 4C and connecting them with a bolt and nut in the center hole is used as the part for a flexible clamp. However, a clearance was provided between the circular part 1 and the hexagonal part 4C so that the circular part and the hexagonal part could slide circularly.

[0018] A single tube was held at a predetermined angle on the holding piece 12 of the commercially available universal clamp 10 equipped with the above-mentioned universal clamp parts, and the nut of the holding piece was tightened from the polygonal part. When the universal clamp parts were installed, it was manufactured slightly higher than the bottom of the fixed piece pipe receiver 14 in Fig. 11 of the commercially available universal clamp 10. Therefore, the tightening force was transmitted to the circular part 1, and the circular part 1 was fixed (in the case of the polygon 4C). Saying that the circular part 1 was fixed means that the other clamp was fixed and the angle between the clamps was fixed. It was transmitted from the hexagonal part to the press-side base part, the other clamp was fixed, and the angle between the clamps was fixed.

Industrial Applicability

[0019] It can be used outside the assembly jig. Usage Example 1 Entertainment field (It can be used for modeling body members such as stages for events, etc.). Usage Example 2 Agricultural field (Greenhouses, fences for protecting birds and animals, etc.). Usage Example 3 Construction field (Slope protection fences, etc.).
