Description

Technical Field

[0001] The utility model relates to the technical field of steel bar binding, in particular to a steel bar binding wire binding device. Background Art

[0002] During the reinforcement construction process, the lap joints of the reinforcement should be tied fast with wire at the center and both ends of the joints. The intersections of the vertical reinforcement mesh in the reinforcement skeleton of walls, columns and beams should all be tied, the intersections of the upper reinforcement mesh should all be tied, and the bottom reinforcement mesh can be tied alternately except for the edge parts.

[0003] The traditional method of tying steel bars with wires is to align and fold a wire in half to form a wire with a hole at one end and two heads at one end. Then, the wire is passed under the crossbar and bent to the top. The wire-tying hook with a handle that can be rotated is passed through the hole end of the wire and wrapped around the two ends. By exerting force with the hand, the wires at both ends are intertwined to achieve the purpose of tightening the intersection of the steel bars. However, using a handle to fix and rotate the hook requires wrist force to control the force and direction. The steel bar tying speed is slow, and it is time-consuming and laborious to tie a large number of steel bars. In addition, repeated wrist twisting can easily cause wrist strain on construction workers, greatly reducing work efficiency and productivity. Utility Model Content

[0028] refer to Figures 1 to 2 A steel bar wire binding device according to an embodiment of the utility model is described.

[0029] like Figure 1 to Figure 2 As shown, a steel bar wire binding device includes a handle 100, one end of which is axially provided with an external thread 110; a sleeve 200, the sleeve 200 is movably sleeved on the handle 100, and the inner wall of the sleeve 200 is provided with an internal thread 210 that can cooperate with the external thread 110, and the sleeve 200 can slide back and forth axially on the handle 100 with the internal thread 210; a hook 300, the hook 300 is arranged at one end of the handle 100, and the hook 300 and the external thread 110 are located on the same side of the handle 100.

[0030] like Figure 1As shown, a hook 300 is provided at the lower end of the handle 100, and a sleeve 200 is sleeved on the handle 100, and the length of the sleeve 200 is less than the length of the handle 100, and an external thread 110 is provided at the lower part of the handle 100 along the up and down directions, and an internal thread 210 that can cooperate with the external thread 110 is provided on the inner wall of the sleeve 200, and through the mutual cooperation between the internal thread 210 and the external thread 110, the sleeve 200 can slide up and down along the axial direction on the handle 100. The construction worker controls the hook 300 to hook the steel bar wire, then holds the sleeve 200 and forcefully pulls the sleeve 200 axially along the handle 100. The handle 100 rotates relative to the sleeve 200 with the cooperation of the internal thread 210 and the external thread 110, and at the same time drives the steel wires to entangle with each other, thereby achieving the purpose of tying the steel bars. The operation is simple and convenient, and the tying speed is fast, which greatly improves the construction efficiency. At the same time, the tying process does not require wrist force, thereby reducing the possibility of wrist strain of the construction workers and providing protection for the health of the construction workers.

[0031] In some specific embodiments of the present invention, a blocking portion 400 is further included. The blocking portion 400 is disposed on the other end of the handle 100 opposite to the hook 300 , and the blocking portion 400 is used to separate the sleeve 200 from the handle 100 .

[0032] like Figure 1 As shown, a blocking portion 400 is provided at the upper end of the handle 100. In the present specific embodiment, the blocking portion 400 is a circular plate arranged perpendicular to the handle 100, wherein the outer diameter of the circular plate is larger than the outer diameter of the sleeve 200. When the internal thread 210 and the external thread 110 are disengaged, the sleeve 200 can be prevented from falling from the upper end of the handle 100.

[0033] In some specific embodiments of the present invention, a connecting portion 500 is further included. The connecting portion 500 is arranged at one end of the handle 100. The hook 300 is connected to the handle 100 via the connecting portion 500. The connecting portion 500 can facilitate construction workers to operate in a complex space.

[0034] like Figure 1As shown, the lower end of the handle 100 is provided with a connecting portion 500, the upper end of the connecting portion 500 is connected to the external thread 110, and the lower end is connected to the hook 300. In this specific embodiment, the connecting portion 500 is conical, and the cross-sectional area of ​​the connecting portion 500 gradually decreases along the external thread 110 toward the hook 300, that is, the cross-sectional area of ​​the upper end of the connecting portion 500 is greater than the cross-sectional area of ​​the lower end. Further, the lower end of the connecting portion 500 smoothly transitions with the hook 300, and the projection of the hook 300 in the up and down direction is smaller than the cross-sectional area of ​​the handle 100. Thus, in a complex steel bar binding environment, construction personnel can insert a steel bar wire binding device in this specific embodiment into the steel bar connection point to perform precise binding operations. On the other hand, the gradual reduction in the cross-sectional area of ​​the connecting portion 500 is conducive to providing a better field of view, reducing obstructions and blockages, and enabling construction personnel to see the area being operated more clearly.

[0035] In some specific embodiments of the present invention, an elastic member 120 is sleeved on the handle 100, and the elastic member 120 is located between the sleeve 200 and the blocking portion 400. One end of the elastic member 120 is connected to the sleeve 200, and the other end is against the blocking portion 400. The elastic member 120 can drive the sleeve 200 to reset.

[0036] like Figure 1 and Figure 2 As shown, a spring is sleeved on the handle 100, the lower end of the spring is connected to the sleeve 200, and the upper end of the spring can be against the blocking part 400. When the construction personnel pull the sleeve 200 in the direction away from the hook 300, the sleeve 200 moves relative to the handle 100 in the direction close to the blocking part 400, and the spring is compressed under the force. After the steel bar binding is completed, the hook 300 is separated from the steel wire and the pulling of the sleeve 200 is stopped. The compression spring has a tendency to rebound. Therefore, the handle 100 slides relative to the sleeve 200 under the action of the compression spring, and the hook 300 moves in the direction close to the sleeve 200, thereby restoring the handle 100 and the sleeve 200 to their original position.

[0037] In some specific embodiments of the present invention, an easy-holding portion 220 is provided on the sleeve 200 , and the easy-holding portion 220 is used to facilitate construction workers to hold the sleeve 200 .

[0038] like Figure 1 and Figure 2 As shown, the sleeve 200 is provided with an easy-holding portion 220. In this specific embodiment, the easy-holding portion 220 is a groove symmetrically provided on the sleeve 200, and the groove is located at opposite ends of the sleeve 200. It is conceivable that the easy-holding portion 220 can also be an annular groove provided on the sleeve 200, and the groove and the outer wall of the sleeve 200 are smoothly transitioned to facilitate construction workers to hold it at multiple angles.

[0039] Furthermore, a plurality of anti-slip strips 221 are provided on the easy-holding portion 220, and the plurality of anti-slip strips 221 are arranged in sequence along the axial direction of the handle 100. The plurality of anti-slip strips 221 can prevent the construction workers' hands from slipping off the sleeve 200, so as to help the construction workers to effectively exert force on the sleeve 200 and reduce the binding burden of the operator.

[0040] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
