Description

[Detailed description of the invention] (Industrial application field) This invention relates to a line cutting stand for filamentous bodies such as electric wires or wires.

(Prior Art) Conventionally, when cutting an electric wire or the like wound around a drum or the like, one worker holds the electric wire or the like with his hands, and the other worker cuts it with a cutter. Usually, electric wires or wires are wound around a drum for convenient transportation and storage, but when you try to cut the electric wires or wires by letting them out from this drum, the cut ends bounce back because of the curls. When attempting to cut the wire, the operator must hold down the cut end of the wire.

(Problem that the invention aims to solve) However, even in recent electrical work sites, work is being carried out with the minimum number of people necessary, so
When cutting electric wires or wires, it is difficult to secure two or more workers. Therefore, in many cases, a single worker cuts the electric wire or wire, and there is a risk of injury to the worker's hands, face, etc. due to rebound due to the rigidity of the wire, such as curling of the wire as described above.

(Means for Solving the Problem) Therefore, this invention, when cutting these striated bodies such as electric wires and wires, presses both sides of these striated bodies to be cut, and prevents the striated bodies during cutting. The present invention aims to solve the above problem by providing a line cutting table that prevents jump-up.

The specific structure of this invention is that a notch is provided at one side edge of the central part of the base, and the corresponding one side walls are located on the base on both sides of this notch so that they are aligned approximately in a straight line. The pressing protrusions are each fixed so that the pressing protrusions are fixed, and a rotating plate having an arcuate side surface on one side, the radius of the center part of which is smaller than the radii of both sides, is mounted on the base, facing each of these pressing protrusions. of each of these rotating plates, both sides of the arcuate side surface can freely come into contact with one side wall of each of the pressing protrusions, and the center part of the arcuate side surface is always positioned at a distance from the one side wall. Further, a bullet is provided which urges one side of the arcuate side of each of these rotary plates to always come into contact with one side wall of each of the pressing protrusions.

(Function) When each of the above-mentioned rotating plates is rotated against the force of the bullet, and the center part of the circular arc side surface of each rotating plate is opposed to one side wall of each pressing protrusion, each rotating plate and each pressing A gap is created between the protruding piece and the filament to be cut is inserted into this gap. When you release your hand holding each rotating plate, it rotates due to the force of the bullet, and the filament is held between one side of each pressing protrusion and one side of the arcuate side of each rotating plate. . In this way, the filamentous body is held between each of the pressing protrusions and the rotating plates on both sides, and the filamentous body located between these clamping points is straddled over the notch in the center of the base. It takes shape. Even if a filament with a crotch on the notch is cut with a cutter or the like, the cut end of the filament will not jump up because it is held between both sides of the base. Moreover, even if tension is applied to the cut strands in the direction in which the strands move away from each other, the large-diameter sides of the arcuate sides of each rotating plate will push against the movement of the strands in this direction. The abutting protrusions are rotated so as to approach one side wall of the abutting protrusions, and the filament is strongly held between the one side wall of each abutting protrusion and each rotating plate.

(spindle support) An embodiment of this invention will be described below with reference to the drawings.

A base 1 having legs 1a on both sides is provided, and a notch 2 is bored inward from one side edge of the center of the base 1.
are provided, and approximately rectangular parallelepiped-shaped pressing protrusions 3 are fixed on the base 1 on both sides of the notch 2. The corresponding one side walls 3a of each of these pressing protrusions 3 are located substantially in a straight line with each other, and a V-groove 3b is provided in the longitudinal direction of each one side wall 3a. Rotating plates 5, 5 are supported on the base 1 by a bolt shaft 4 so as to be rotatable in the horizontal direction, respectively, facing each of the pressing protrusions 3. Each of these rotating plates 5 is approximately semicircular with an arcuate side surface 5a on one side and a straight side surface 5b on the other side, but the radius of the center part of the arcuate side surface 5a is smaller than the radius of both sides. It is. Even if each rotary plate 5 is rotated to face one side wall 3a of each pressing protrusion 3, a gap is created between the central portions of the arcuate side surfaces 5a of each of these rotary plates 5.
Both sides of the arcuate side surface 5a can come into contact with one side wall 3a of each pressing protrusion 3. Each of these arc sides 5
A is further knurled to prevent slipping. Further, one end of a handle 6 is fixed to the linear side surface 5b of each rotating plate 5. Above base 1
A pedestal 7 is fixed to the center portion of the pedestal 7 with a screw 8, and a through hole 9 is bored through both end surfaces of the pedestal 7. A support post 10 is provided at the center of the through hole 9, and each through hole 11 is fixed at one end to the support post 10, and the other end is bored at the end of the fixed portion of each handle 6 to each rotating plate 5. A spring 12, 12 that is engaged with the through hole 9 is provided in the through hole 9. Each rotating plate 5 is urged to rotate around the bolt shaft 4 by the force of each of these springs 12, and one side portion of each arcuate side surface 5a is pressed against one side wall 3 of each pressing protrusion 3. A substantially sector-shaped stopper 13 is pivotally supported on the upper surface of each of the pressing protrusions 3 by a shaft 14 provided at its base.
It is rotatably provided in the horizontal direction. Each of these stoppers 13 is provided with a curved long hole 15,
A piston 16 protruding from the upper surface of the pressing protrusion 3 freely passes through each of these curved elongated holes 15, and the rotation range of each stopper 13 about the axis 14 is regulated by this curved elongated hole 15. The stopper 13 can freely protrude outward from one side wall 3a of each pressing protrusion 3. Reference numeral 17 designates holes for hooks drilled in each of these stoppers 13.

In this embodiment, the two handles 6 on both sides are urged toward each other by springs 12, 12, but in order to cut the electric wire 18 using this wire cutting table, each of the springs 12 When the two handles 6, 6 on both sides are pushed apart from each other against the force, each rotation plate 5 rotates around the bolt shaft 4, and each rotation plate 5 rotates on one side wall 3a of each pressing protrusion 3. The center portions of the arcuate sides 5a of the plate 5 face each other, and gaps 19, 19 are created between each side wall 3 and each arcuate side 5a, as shown in FIG. 3, respectively. In this state, when the electric wire 18 is placed in the gaps 19, 19 on both sides of the part to be cut and the handles 6 are released, each rotating plate 5 rotates around the bolt shaft 4 due to the force of the spring 12. , one side of the electric wire 18 is pressed into the V-groove 3b of one side wall 3a of each pressing protrusion 3, and the other side is pressed against one side of the arcuate side surface 5a of each rotating plate 5, and is held between them. Ru. As a result, as shown in FIG. 4, the part of the electric wire 18 to be cut is located on the notch 2 of the base 1, and both sides of the electric wire 18 are gripped and fixed by the pressing protrusion 3 and the rotating plate 5.
Each stopper 13 is rotated about the shaft 14 so that one end of each stopper 13 protrudes above one side of the arcuate side surface 5a of each rotating inverter 5. Then, the worker places one foot on the pedestal 7,
Cut the electric wires at 18 locations located above the cutout portion 2 with a cutter. Even if the electric wire 18 is cut, each cut end is held by the wire cutting table, so that it will not spring upward or come off to the outside. Furthermore, in this embodiment, even if the electric wire 18 is not held tightly between the pressing protrusions 3 and the rotary plate 5, the stopper 13 protrudes above the electric wire 18 at this clamping point, so that the electric wire 18 will be bounced off when cutting. It doesn't go up.
Then, the operator presses the cut end of each cut electric wire 18 with his/her hand, turns the handle 6, and presses each pressing protrusion 3.
and each rotating plate 5.

(Effects of the invention) This invention has the above-mentioned configuration. When cutting electric wires, wires, and other filamentous bodies, the wire cutting table of this invention is placed at an appropriate location, and both sides of the filament are cut. Since the wire is held between both sides of the wire cutting table, even if the wire is cut by a single worker, there is no risk of the cut end bouncing back and causing injury to the worker. Therefore, line cutting can be carried out safely by a single worker without requiring multiple workers as in the past. Furthermore, the wire cutting table of this invention has an extremely simple structure, so it can be carried anywhere. Further, the work for fixing the filament to the wire cutting table is extremely simple, as it is sufficient to rotate each rotary plate against the force of the bullet and insert it into the gap between each pressing protrusion and each rotary plate. Furthermore, since the cutting portion of the filament is located on the notch of the base, it is in a floating state, making it easier to apply a cutter or the like to the filament.
