Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a wire drawing roller used when a cable is drawn.

(Prior Art) Previously, the applicant of the present application filed a utility model registration application for a device relating to a wire drawing roller as shown in FIG. 1 as a lightweight and easy to handle wire drawing roller (Japanese Patent Application No. 1-84403). (Actual Kaihei No. 3-26207)). This wire-drawing roller is formed by a plurality of roller bodies 10a, 10b, 10c which are arranged in an annular shape and to which the respective rotation support shafts 11a, 11b, 11c are connected, and the end faces of the roller bodies adjacent to each other. A plurality of connecting members 13a, 13b, 13c having a shape that complements the recessed portion to be formed, at least one roller body
One end 14a of the rotary support shaft 11a of 10a is connected to one connecting member 13b by a hinge 9, and the other end 14b is slidably disposed in the inner hole 15 of the other connecting member 13a. A magnet 17 that is detachably locked to the pin 16 and that constantly attracts one end of the movable pin 16 and a lever 21 that is connected to the movable pin 16 are provided in the inner hole 15 of the connecting member 13a. When using, the movable pin 16 is slid along the inner hole 15 via the lever 21 to open / close the roller body 10a connected by the hinge 9 to insert / extract the cable.

(Problems to be solved by the invention) In such a wire drawing roller, the shaft center of the movable pin 16 and the inner hole 1 of the connecting member 13a are used when the roller body is opened and closed.
It is important for operation of the movable pin 16 that the axis of 5 is aligned, and if the axes of both are misaligned, the work of closing the roller body cannot be performed smoothly.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a wire drawing roller capable of smoothly performing the work of closing the roller body.

(Means for Solving the Problems) That is, the wire-rolling roller of the present invention is provided with a plurality of roller bodies arranged in an annular shape and connected to respective rotary support shafts, and end faces of the roller bodies adjacent to each other. A plurality of connecting members having a shape that complements the recess formed by
A hinge that connects one end of the rotation support shaft of at least one roller body to one connection member, a through hole provided at the other end of the rotation support shaft, and an inner connection provided at the other connection member. In a wire drawing roller provided with a movable pin disposed so as to be slidably fitted in a hole, each of the opposite ends of the other end of the rotation support shaft and the other connecting member joined to the other end. The surface is provided with a recess and a protrusion that can be detachably engaged.

(Operation) In the wire drawing roller of the present invention configured as described above,
Only by locking the recesses and protrusions of the rotary support shaft and the connecting member, the axis of the movable pin and the axis of the connecting member inner hole can be automatically aligned, and the roller body is closed. Can be done smoothly.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 to 4 are views showing an embodiment of the present invention. In these figures, the three roller bodies 10a, 10b,
The 10c are arranged so as to form a ring shape with each other. These roller bodies are provided with rotary support shafts 11a, 11a arranged at their axial centers.
It is rotatably supported by bearings 12 on b and 11c.

The ends of the rotation support shafts 11a, 11b, 11c of each roller body are connected via three connecting members 13a, 13b, 13c, respectively.

Therefore, the one end portion 14a of the one rotation support shaft 11a is connected to the one connection member 13b by the hinge 9. The other end 14b of the rotation support shaft 11a is, as shown in an enlarged scale in FIG. 2, inside the through hole 15 of the other connecting member 13a and inside the through hole 8 provided at the other end 14b of the rotation support shaft 11a. The movable pin 16 is slidably disposed on the shaft and is detachably locked.

Inside the through hole 15 of the connecting member 13a, a magnet 17 that constantly attracts one end of the movable pin 16, a cushion rubber 18, and a tightening screw 19 are provided. The tightening screw 19 is screwed into a screw groove 20 provided on the inner circumference of one end of the through hole 15, and presses the magnet 17 via the cushion rubber 18.

A lever 21 is connected to the movable pin 16. This lever
One end of 21 is fixed to the movable pin 16, and the other end is the connecting member 13a.
It is exposed on the outer surface of and can be moved along the guide groove 22 provided on the outer surface of the connecting member 13a.

As shown in the enlarged view of FIG.
The other end 14b of a and the connecting member 1 joined to the other end 14b
A recess 7 and a protrusion 6 which can be detachably engaged with each other are provided on each surface facing the 3a.

The connecting members 13a, 13b, 13c have a shape that complements the concave portion formed by the end faces of the roller bodies adjacent to each other, in other words, 3
It has a fan shape that complements the annular shape formed by the roller main bodies 10a, 10b, 10c.

Each connecting member is provided with a through hole for locking a hanging member 24 (FIG. 4) such as a hook, that is, a hanging member locking portion 25.

When the wire drawing roller of the present invention is used, as shown in FIG. 4, a hanging member 24 such as a hook or a hanging wire is hooked on the hanging member locking portion 25 of the connecting member 13c to hang it. . Next, by moving the lever 21 along the guide groove 22, the movable pin 16 is disengaged from the magnet 17 that is always adsorbed, and disengaged from the through hole 8 of the rotary support shaft 11a, so that the roller body 10a is connected to the connecting member 13a. Remove from. And cable
After the 26 is positioned in the plurality of roller bodies that are annularly arranged, the movable support pin 16 is inserted into the through hole 8 by locking the recesses 7 and the protrusion 6 of the rotation support shaft 11a and the connecting member 13a. Close the roller body.

The magnet 17 is tightened with a tightening screw 19 via a cushion rubber 18 for protection.
Thus, the magnet 17, which is fixed to the connecting member 13a and has a reduced magnetic force, can be easily replaced.

(Effects of the Invention) As described above, the wire drawing roller of the present invention has a recessed portion that can be detachably engaged with each of the facing surfaces of the end of the rotation shaft of at least one roller body and the connecting member joined to the end. By providing the protrusion and the protrusion, respectively, the axis of the movable pin and the axis of the connecting member inner hole can be automatically aligned with each other, so that the work of closing the roller body can be smoothly performed.
