The present invention relates to an electric wire winding roll fixing device, and more particularly, to an apparatus for freely fixing a plurality of electric wire winding rolls used for winding an electric wire to a shaft.

Conventionally, when it is necessary to wind or unwind a wire such as a rope when necessary, a plurality of wire winding rolls are installed on a shaft rotated by a motor to perform the work of unwinding or winding the wire.

However, in the above structure, since a plurality of electric wire winding rolls are rotated at the same time to the outside of the axis rotated by the driving of the motor, even the electric wire winding rolls which do not need to rotate are rotated, causing a power loss of the motor rotating the shaft. there was.

The present invention has been made in view of the above problems, an object of the present invention is an electric wire winding roll fixing device that can be easily stopped by the operator to stop the electric wire winding roll to be stopped among a plurality of electric wire winding rolls installed on the outer side of the shaft In providing.

In order to achieve the above object, the present invention, in the structure in which the electric wire winding rolls are provided at both ends while maintaining a predetermined distance interval on the upper portion of the base plate, the at least one hool on the shaft The electric wire winding roll fastened to the plate of the electric wire winding roll while maintaining a predetermined distance with the clutch so as to be penetrated and contacted by the other hool to be installed in contact with the hool, and the hool of the shaft and the hool of the clutch. And an anti-rotation bracket fastened to the upper portion of the base plate while maintaining a fixed distance from the end of the wire winding roll fixing device, wherein the wire winding roll fixing device has a hole therethrough. A rod is inserted into the rod insertion bracket and the hole of the rod insertion bracket, and at the same time, a spring is installed outside. At the same time as the rod and the pin is fastened to the rod and at the outer part of the spring is installed in the middle part of the hook ring is integrally installed in the middle portion and a plurality of hook grooves are formed, the spring and the ball to be caught in the hook groove And a locking bracket fastened to the rod insertion bracket and a locking jaw fastened to the rod.

Hereinafter, the present invention will be described with reference to the accompanying drawings. Figure 1 is an exploded perspective view showing a wire winding roll fixing device of the present invention, Figure 2 is a side view according to the present invention, the plate 12a is installed at both ends while maintaining a certain distance interval on the base plate 10 In the state in which several wire winding rolls 14 are installed around the shaft 16, the shaft 16 penetrates the horn 18a which the predetermined distance was hold | maintained by the number of the wire winding rolls 14, respectively, and this shaft At the outer side of 16, a clutch 20 through which another hoel 18b of the same shape and size as that of the hoel 18a of the shaft 16 is provided.

In addition, the electric wire winding roll fixed to the side of the plate (12a) of the electric wire winding roll 14 can be fitted as necessary to the hoel 18a of the shaft 16 and the hoel 18b of the clutch 20 at the same time. The device 22 is installed, and the wire winding roll fixing device 22 is as follows.

A long rectangular rod insertion bracket 26 having a movement preventing plate 24 protruding at one end and a long hole 18c penetrating at the center thereof; The rod is inserted into the rod 18c of the rod insertion bracket 26 and at the same time, the rod 32 a is provided with a fastening hole 30 to which the spring 28a is elastically installed, and the rod 30 through the fastening hole 30. A spring 28b having a relatively smaller spring constant than the spring 28a is installed at the same time as the pin 32 is fastened to the pin 34, and the locking ring 36 is integrally formed in the middle portion. And another rod 32b having three locking grooves 38a, 38b, and 38c formed in the vicinity of the locking ring 36, and the locking grooves 38a and 38b of the rod 32b. A locking bracket 42 which is fastened to the insertion bracket 26 with another spring 28c having a smaller size than the springs 28a and 28b and a spherical ball 40 so as to be caught by the 38c. ). In addition, a threaded portion 44 is formed at the end of the rod 32b, and a knob 48 having a locking projection 46 protrudes is formed at the threaded portion 44.

And while maintaining a predetermined distance from the end of the wire winding roll fixing device 22 is formed by fastening a plurality of bolts 52 of the anti-rotation bracket 50 on the upper portion of the base plate (10).

In this configuration, first, among the electric wire winding rolls 14 installed around the outer periphery of the shaft 16, the electric wire 54 is set to be unwound or sensed, that is, not used.

The electric wire provided in the side of the electric wire winding roll 14 which is not to be used, in the state (c) of FIG. 3 in which the rod 32a of the electric wire winding roll fixing device 22 was inserted in the hole 18a of the shaft 16. When the knob 48 of the take-up roll fixing device 22 is pulled in the opposite direction to the shaft 16, it is in the state of (b) of FIG. 3, which means that the rods 32a and 32b fastened to the knob 48 As the ball 40 embedded in the locking bracket 42 is pushed backward and moved from the locking groove 38a, the shaft 16 is positioned at a desired position by the spring 28c force, that is, the locking groove 38b. The rod 32a inserted into the hool 18a of the is pulled out.

Accordingly, when the shaft 16 is rotated by the rotation of the motor, the rod 32a is missing from the hoel 18a of the rotating shaft 16, so that the wire winding roll 14 which does not want to rotate is not rotated as a result. By doing so, the power loss of the motor can be reduced as much as possible.

In the above, the electric wire winding roll 14 is not rotated by the motor, but the electric wire 54 can be manually unwound or wound since the electric wire can be rotated by the operator's operation.

Then, when the knob 48 is pulled in the opposite direction to the shaft 16 again in the state of FIG. 3 (b), the state of FIG. 3 (a) is obtained. This is because the ball 40 embedded in the locking bracket 42 has a rod ( When the ball 40 reaches the proximal portion of the locking groove 38c when the ball 40 is easily moved by the force of the spring 28b in the locking groove 38b of 32b), the force of the spring 28c embedded in the locking bracket 42 is applied. The ball 40 is located in the locking groove 38c and the rod 32b is completely protruded, so that the knob 48 coupled to the rod 32b is provided on the anti-rotation bracket 50 installed on the base plate 10. I get caught. Therefore, the wire winding roll fixing device 22 and the wire winding roll 14 fastened to the anti-rotation bracket 50 are not rotated in one direction, as well as are not rotated by a manual operation of an operator.

In the state where the ball 40 of the locking bracket 42 is (a) of FIG. 3 positioned in the locking groove 38c, the knob 48 is pushed in the direction of the axis 16 so that the ball located in the locking groove 38c. 40 is primarily positioned in the locking groove 38b by the spring 28a, and the ball 40 is secondarily caught in the locking groove 38a of the rod 32b, and at the same time, the rod 32a is rotated by the shaft 16. The wire winding roll 14 is rotated in the same direction as the shaft 16 by the driving of the motor by being inserted into the hool 18a of the wire 18 so that the wire 54 can be wound or unwound.

In order for the rod 32a of the wire winding roll fixing device 22 to be smoothly inserted into the hole 18a of the shaft 16, the spring constant of the spring 28a should be larger than the spring constant of the other spring 28b. Do.

On the other hand, since the movement preventing plate 24 of the wire winding roll fixing device 22 is formed between both plates 12b of the clutch 20, the shaking of the clutch 20 and the wire winding roll fixing device 22 is prevented. Prevented.

According to the wire winding roll fixing device of the present invention as described above, the shaft that is rotated by a motor to the wire winding roll 14 to be stopped in a plurality of wire winding roll 14 installed to the outside of the shaft 16 ( By releasing power from 16, it is possible to reduce the power of the motor as much as possible.
