Description

Reinforcing Bar Binding Machine {Connector for Reinforce Iron Core Connecting Wire}

The present invention relates to a reinforcing bar binding machine, and in detail, the binding line is firmly bound by only the operator pulling a handle so as to reduce the labor of the worker and make the reinforcing work more effectively.

In general, reinforcing bars in the construction site are designed to withstand the loads and stresses required by the structural structure of the building.In the case of reinforcing bars, they are fixed by crossing each other and placing the formwork and placing concrete. do. On the other hand, thin wrought iron is generally used to bond such bars.

The reinforcing bar binding line was made of cutting the soft iron to the required length, so that the worker had to carry it around and twisted the reinforcing bars so that the reinforcing bars did not flow by using a manual twirl at the position where the binding was needed.

This reinforcing bar binding work was forced to rely entirely on manpower not only takes a lot of work time, but also had a lot of burden on the wrist of the worker because the workers had to repeat a number of simple tasks.

The present invention has been devised to solve the above-mentioned conventional problems, the object of the present invention can be made to bind the reinforcing bars more quickly, and reduce the burden on the wrist operator can also perform effective reinforcing bar binding work To provide a means.

In order to achieve the above object, the present invention provides a hook that is coupled to the tip and the outside of the hook so that the strap is automatically and firmly twisted when the worker inserts the hook of the tip into the strap and pulls the handle while the strap is tied. A shaft having a spiral groove formed therein, a handle formed in a tubular shape so that the shaft is fitted therein, a spindle having a ball coupled to the tip of the handle and fitted into the spiral groove of the shaft, a bearing coupled to the rear end of the shaft, Provided is a reinforcing bar binding apparatus including a restoring spring located inside the handle and positioned between the bearing and the spindle.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view of a binding device according to the present invention, Figure 2 is an exploded perspective view of the binding device according to the present invention, Figure 3 is a cross-sectional view of the binding device according to the present invention.

As shown in FIGS. 1 to 3, the binding device of the present invention has a shaft 20 having a hook 10 coupled to a tip and a spiral groove 22 formed on an outer side thereof, and a tubular shape such that the shaft 20 is fitted thereto. A spindle 40 having a handle 30, a ball 42 coupled to the tip of the handle 30 and fitted into a spiral groove 22 of the shaft 20, and the shaft 20. It comprises a bearing 50 coupled to the rear end, and the restoring spring 60 is accommodated in the handle 30 and located between the bearing 50 and the spindle 40.

The spiral groove 22 formed on the outer side of the shaft 20 is preferably formed in a double helix, it is preferable to install two balls 42 in the spindle 40, but the present invention is not limited thereto. Do not.

The spindle 40 may be fixed to the distal end of the handle 30 by interference fitting or screwing, and the shaft hole 44 is formed in the center of the spindle 40 so that the shaft 20 penetrates and slides. The ball 42 projects into the shaft hole 44 and fits into the spiral groove 22 of the shaft 20 penetrating the shaft hole.

The handle 30 is subjected to a nuling process on the outside to facilitate the operator to hold the handle and at the same time to prevent slipping from the hand when pulling the handle.

The rear end of the handle 30 is covered with a cap 70 to prevent the inflow of dirt or other foreign matter inside.

The bearing 50 coupled to the rear end of the shaft 20 is for removing friction with the inner surface of the handle 30 when the shaft 20 is in and out of the shaft 20, so as not to interfere with the indentation of the shaft 20. Allow sufficient clearance between the inner walls of the handle.

Reference numeral 52 in the figure denotes a key washer for fixing the bearing 50 to the rear end of the shaft 20.

1 to 3, in the present invention, the spiral groove 22 formed on the outer surface of the shaft 20 determines the rotation speed of the shaft 20, so that the pitch is shorter or longer. Can be formed to obtain the required rotational speed.

The present invention configured as described above has a hook at the tip of the binder of the present invention in a state in which the worker winds and binds the binding line W to the intersection or binding portion of the reinforcing bar I as shown in FIGS. 4A and 4B ( 10) is inserted into the binding portion of the binding line (W) and pull the handle 30, the internal shaft 20 is rotated by the retraction of the handle 30, which is formed outside the shaft 20 This is because the ball 42 of the spindle 40 fixed to the tip of the handle 30 is fitted in the spiral groove 22.

The binding line W, which is temporarily bound by the operation of pulling the handle 30 as described above, is firmly bound while being twisted several times.

The operator can adjust the binding force of the binding line (W) by simply adjusting the pulling force of the handle (30), and after removing the force from the pulled handle (30) after the binding is completed, the front of the handle (30) The shaft 20, which has been protruded into, is moved back into the handle by the inner restoring spring 60.

As such, when the binding device of the present invention takes only the operation of pulling the handle 30 by the operator, the shaft 20 rotates so that the hook 10 at the tip of the shaft 20 twists the binding line W. Compared to using manual tweezers to tie the straps, the operator does not have to use the wrists much, which greatly reduces fatigue due to stiffness of the muscles of the wrist and excessive use of the wrists. You can do it.

As described above, the binding device of the present invention is to bind the binding line while the hook of the tip is rotated by the operation of pulling the handle, so that the operator does not have to rotate the wrist, so even an inexperienced worker can quickly bond the binding line. It is possible to reduce the fatigue of the wrist felt during work, and thus has a practical effect that can improve the workability when binding the rebar.
