ROTARY DEVICE FOR BINDING IRON ROD [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a rotary shaft for binding a reinforcing bar, and more particularly, to a rotary shaft for reinforcing bar binding, which is convenient for an operator to work,

Related to the reinforcing bar binding rotary bar used for reinforcing bar binding work, the present applicant has been registered in various forms and registered. As a representative example thereof, Korean Patent Registration No. 10-0531197 entitled " Reinforcing Wing Rotor, " Korean Patent Registration No. 10-1065267 entitled " Rotor for Reinforcement Bonding ", Korean Patent Registration No. 10-1190501, Quot; and Korean Patent Registration No. 10-1211557 " Reinforcing Barrel ".

The operator first roughly ties the wires to the intersections of the reinforcing bars intersected up and down and left and right and then rotates them so as to securely engage with the wire twisting portions that are roughly bundled through the claw portions formed at the ends of the binding rods of the reinforcing bar binding rotary bar give.

It is important to configure such that the rotation of the binding rod that is rotatably provided on the handle is smoothly performed in such a reinforcing bar binding rotary barrel and that the binding bar is rotated by rotating the binding bar so that the hand slips off the handle It is more important than anything else.

However, in the conventional reinforcing bars for rotating the reinforcing bars, when the wire binding position is distorted in actual use by an operator, the portion is usually used as a tool for hammer replacement by the rear portion of the rotary tool to hold it in place. At this time, Since the molded metal handle is heavy and inconvenient to use, it is more expensive than synthetic resin, which is a cause of increasing manufacturing cost.

To solve this problem, the applicant of the present invention has proposed a method for manufacturing a steel pipe having a stainless steel single pipe having a circumferential portion formed on the inner surface of a pipe of a handle in a domestic patent registration No. 10-1211557 " It can be used as a hammer as well as a handle, and it is lightweight and has excellent advantages in quality and price competitiveness.

However, since the wire is subjected to rotational resistance due to contact with the rotating rod and the head portion of the resin material end pipe during the binding operation, the rotation is not smooth and the inner diameter portion of the head portion of the endothelium tube is worn out due to friction with the binding rod. The turning radius of the binding rod that rotates about the axis of the knob is gradually changed, so that the rotation of the binding rod is not constant and the operation is considerably inconvenient.

In addition, the rotary handle is pulled back while rotating the binding rod. In this case, the conventional handle is provided with a circumferential protrusion so as to prevent the handle from slipping when the handle is gripped. However, when holding the handle, Because it is made of metal material, it is not only slippery but also the outer surface formed with the circumferential stones is flat, so it is necessary to hold the hand tightly and it takes a lot of force and it is easy to miss the handle. will be.
In the case of the Japanese Patent Registration No. 10-1190501 entitled " Rotary Socket for Reinforcing Bars ", the idle rotating body 20 is coupled to the upper end of the handle 30 so as to rotate as the binding rod 10, However, when the binding rod 10 is rotated in the field, the idler rotating body 20 is shaken and swings to the binding rod 10 rather than being rotated. As a result, .
The idle rotating body 20 is configured to rotate within the handle 30 so that a slight clearance is formed between the axial base 26 of the idle rotating body 20 and the inner surface of the handle 30, The upper body 12 is eccentrically fixed with respect to the lower body 14 so that the upper body 12 rotates while eccentrically pushing the idler body 20 when the upper body 12 rotates, And the binding rods 10 are also shaken while rotating, resulting in a greater strength in the binding business.

Korean Patent Registration No. 10-0531197 entitled " Korean Patent Registration No. 10-1065267 entitled " Korean Patent Registration No. 10-1190501 entitled " Korean Patent Registration No. 10-1211557 entitled "

Accordingly, it is an object of the present invention to provide a method and apparatus for improving the durability of a reinforcing bar for a reinforcing bar, while ensuring that the turning radius of the binding bar is always constant along with the turning force of the binding bar to smooth the rotation and prevent slippage with the bar during operation. And to provide an improved reinforcing bar binding rotary member.
