Description

  The present invention relates to a focusing holder that bundles a plurality of cables and hoses that are routed for a long time in a work site that uses a cutting machine or a welding machine.

  Gas cutting machines are known as devices for cutting steel members and the like at appropriate locations. The gas used in this gas cutting machine may be propane or city gas, but acetylene, which has a high calorific value and uses a small amount of oxygen, is most often used. Then, acetylene and oxygen are burned while being jetted in a mixed state, and the target member is appropriately cut by the heat generated by the combustion.

  Moreover, when welding two members at a construction site or the like, an electric welding machine or a gas welding machine is used. In gas welding machines, acetylene and oxygen are mixed and burned at a high temperature in a burner, and welding work is performed using a welding rod. On the other hand, in an electric welding machine, arc (discharge spark) is generated to melt metal and arc welding. And welding of steel, stainless steel, cast iron, etc. is attained by selecting the welding rod to be used.

  Gas shielded arc welding is also known, and arc welding is performed while jetting shield gas such as carbon dioxide gas or argon gas from around the wire (solid wire or flux wire) supplied to the welding location. .

  FIG. 8A illustrates a state in which the welding cable 11, the base material cable 12, and the remote control cable 13 are led out from the welding machine body 10. The welding cable 11 is connected to the welding rod 15 through the manual welding holder 14, and the base material cable 12 is connected to the base material 17 through the ground piece 16. When used in a factory, commercial three-phase power is supplied to the welding machine main body 10, but three-phase power generated by the generator 20 is supplied to the welding machine main body 10 at a construction site or the like. The

  FIG. 8B shows a system for realizing gas shielded arc welding using carbon dioxide gas. Carbon dioxide gas output from the gas cylinder 21 is transmitted to the wire feeding device 23 via the gas hose 22 and is connected to a single cable. And are supplied to the welding torch 24.

  In FIG. 8, various cables are neatly arranged, but the actual situation is that each cable is scattered randomly in an actual work site. FIG. 9 illustrates the state of use of the electric welder as shown in FIG. 8A. The welding cable 11 and the base material cable 12 led out from the welding machine main body 10 are returned to their original positions for convenience. Has been. 9A shows a state in which the welding machine main body 10 is viewed from a distance, FIG. 9B shows a state of the welding cable 11 and the base material cable 12 that are returned to their original positions after being derived, FIG. 9C shows the lead-out state of the welding cable 11 and the base material cable 12, respectively.

  The cables are scattered in the same manner in the case of a gas welding machine or a gas cutting machine. FIG. 10 illustrates the state of use of the manual gas cutting machine. For convenience, the two gas hoses 27 and 28 led out from the oxygen cylinder 25 and the acetylene cylinder 26 are returned to their original positions for cutting. Connected to the blowing tube 29.

  As is clear from FIG. 9 and FIG. 10, the actual situation is that cables and halls are scattered at the work site, so that they can be caught on the feet of workers and cause a serious accident. There's a problem. In particular, at construction sites, work is often done on the second and third floor steel frames, and this problem is serious. In addition, in electric welding, it is legally required to attach a grounding piece to a location within 2 m from the welding location, so it is necessary to route two cables to that location, and the cables can be bundled appropriately. Of particular importance.

  In consideration of such points, a plurality of cables and hoses may be bundled with an adhesive tape at a work site. However, if they are fixedly bundled in this way, there is a problem that it is very complicated to replace only one bundled plurality. For this reason, the cable with the outer skin worn and the core wire exposed may be left unattended, causing an accident. In the first place, it is extremely troublesome to bundle cables that may extend over 20 m with an adhesive tape.

  The present invention has been made in view of the above problems, and provides a focusing holder that can easily bundle a plurality of cables and hoses and that can be easily removed. The purpose is to prevent accidents.

In order to solve the above-mentioned problems, the present invention is configured such that a plurality of substantially cylindrical bodies (2, 3) having missing grooves (5, 6) continuous in the length direction are integrated back-to-back through the connecting portion (4). A focusing holder made of a molded elastomer material, which is used to insert a plurality of wires at the work site of a cutting machine or a welding machine through the missing groove and hold them in a non-fixed manner without using other members. The open end portion of the substantially cylindrical body is formed to be thicker than other portions, and the length L of the substantially cylindrical body is 10 to 30 cm. By setting the ratio between the inner diameter Φ and the length L of the substantially cylindrical body to 1: 3 to 1: 5, it is possible to route a plurality of wire rods to a target location in an arbitrary path, and in the shape of a spider also possible to organize, wire to the open-end portion is inserted Both end portions of the longitudinal direction are formed is extended.

  Here, the elastomer material means a material having moderate elasticity, but preferably a synthetic polymer material is used, and more preferably, a hard rubber material is used. The open end portion of the substantially cylindrical body is preferably formed to be sufficiently thicker than other portions. It is preferable to embed a metal wire in the thick portion. In addition, it is preferable to provide a non-slip uneven surface on the inner surface that contacts the wire at the open end portion.

  In addition, it is preferable that the opening angle from the center point of each substantially cylindrical body is 45 ° to 110 °, more preferably 75 ° to 100 °, and more preferably about 90 °. It is formed.

Since the present invention holds a plurality of wires at the work site of a cutting machine or a welding machine, the length of one focusing holder is about 10 to 30 cm . More preferably, it is about 10 to 20 cm. If the length of the focusing holder is too short, the holding state cannot be maintained when one of the plurality of wires is lifted. On the other hand, if the focusing holder is too long, a plurality of wires cannot be rolled up and arranged. Therefore, the optimum length is about 15 cm.

The ratio of the inner diameter [Phi and length L of the substantially cylindrical body ([Phi: L) is 1: 3 to 1: about 5. And from the peculiarity which is a wire rod of a cutting machine or a welding machine, it is preferable that the number of wire rods held by the focusing holder (substantially the number of cylindrical bodies) is about 2 to 3. If there are too many wires to be held, the load of the entire wire is too heavy to be rolled up and arranged, and the significance of the present invention is lost.

  According to the above invention, it is possible to realize a focusing holder that can easily bundle a plurality of cables and hoses and that can be easily removed.

  Embodiments of the present invention will be described below based on examples. FIG. 1 is a perspective view showing a focusing holder 1A according to the first embodiment, and this focusing holder 1A is used for focusing a pair of cables and hoses (hereinafter referred to as a wire). The focusing holder 1 is integrally formed of a hard rubber material in order to achieve appropriate elasticity and hardness. The focusing holder 1 is cut in advance to a length L of about 10 to 20 cm after being integrally formed. The illustrated example is about L = 15 cm.

  As shown in the figure, the focusing holder 1 is configured by integrating a pair of substantially cylindrical bodies 2 and 3 having missing grooves 5 and 6 back to back via a connecting portion 4. Here, the inner diameters Φ of the substantially cylindrical bodies 2 and 3 are set to be substantially the same as the outer diameters of the wires, corresponding to the outer diameters of the wires to be accommodated and held. In the illustrated example, Φ = about 4 cm.

  The missing grooves 5, 6 are formed at symmetrical positions of the connecting portion 4 on the circumferences of the substantially cylindrical bodies 2, 3 and extend linearly in the length direction of the focusing holder 1. Here, the open end portions 2a and 3a of the substantially cylindrical bodies 2 and 3 are formed to be sufficiently thicker than the other portions, thereby increasing the holding strength of the wires to be received.

  Further, in the illustrated example, the missing grooves 5 and 6 are formed so that the opening angle θ from the center point of each of the cylindrical bodies 2 and 3 is about 90 °. However, the opening angle θ is not particularly limited, and is appropriately determined in the range of 45 ° to 110 ° based on the hardness of the forming material of the focusing holder 1 and the friction coefficient with the wire to be focused. The

  In use, the pair of wires 7 and 8 to be converged are pushed toward the connecting portion 4 from the missing grooves 5 and 6. In this case, since the focusing holder 1A has an appropriate elasticity, the missing grooves 5 and 6 are opened slightly with the connecting portion 4 as a base point to receive the wires 7 and 8. Then, the received wire is pressed inward by the thick open end portions 2a and 3a and securely held.

  Since the focusing holder 1A is formed to be 10 to 20 cm, the wires 7 and 8 are discretely held by disposing the focusing holder 1A in the extending direction of the wires 7 and 8. The In this way, since the pair of wires 7 and 8 are discretely held by the focusing holder 1A, at the end of the work, the pair of wires 7 and 8 can be easily arranged by rounding them so as to wind a scissors. it can. When one of the wires 7 and 8 is exchanged, the holding state can be canceled by pulling the wire outward from the connecting portion 4 of the focusing holder.

  FIG. 3 is a perspective view showing a focusing holder 1B according to the second embodiment. In this focusing holder, a wire 9 is inserted into the thick open end portions 2a and 3a. The material of the wire 9 is not particularly limited, but a copper needle material is preferably used. According to this embodiment, since the open end portions 2a and 3a extending in the length direction are integrally opened, there is no possibility that both ends in the length direction of the open end portions 2a and 3a are turned up. The holding strength of the wire is further increased.

  4 (a) and 4 (b) are a front view (b) and a side view (b) showing a focusing holder 1C according to the third embodiment. In this focusing holder 1C, both end portions in the length direction of the thick open end portions 2a and 3a are slightly extended, and the holding strength of the wire is increased accordingly. 5A and 5B are a front view (b) and a side view (b) showing a focusing holder 1D according to the fourth embodiment. In this focusing holder 1D, in addition to the configuration of the third embodiment, the wire 9 is inserted into the thick open end portions 2a and 3a, thereby increasing the holding strength.

  FIG. 6 shows a focusing holder 1E that can hold three wires. The focusing holder 1E according to the fifth embodiment also adopts a configuration in which the wire 9 is inserted into the open end portions 2a and 3a and a configuration in which both ends in the length direction of the open end portions 2a and 3a are extended. it can.

  As mentioned above, although the Example of this invention was described concretely, the concrete description content does not specifically limit this invention. For example, in order to increase the holding strength of the wire, a fine groove may be formed in the length direction on the inner surface of the thick open end portion.

  Further, in the above-described embodiment, the focusing holder that has been cut in the length direction in advance has been described, but it is also preferable that the user circulates in a state before cutting and the user himself cuts to the required length.
