Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, in particular to a steel wire binding device for a steel bar framework. Background Art
[0002] In building construction, a large number of steel bar frameworks usually need to be set up. In order to maintain the shape of the steel bar framework, the steel bar framework needs to be bound with steel wires. At present, the steel wire binding either relies on manual labor or uses a special steel bar bundling machine. However, for the existing steel bar bundling machines in the current market, a large amount of manpower, material resources and funds are required, and the price has not reached the popularization level. Therefore, currently, the steel wire is tightened with a steel wire hook to complete the binding work. However, for the existing steel wire hook tools, the hook and the handle are of an integrated structure. When the hook rotates for binding, the handle also rotates in the palm, thus causing frictional damage to the hand, and resulting in the inability of the staff to continuously carry out the binding work for a long time. Summary of the Utility Model
[0003] In order to overcome the problem that for the existing steel wire hook tools, the hook and the handle are of an integrated structure, and when the hook rotates for binding, the handle also rotates in the hand, thus causing frictional damage to the hand, and resulting in the inability of the staff to continuously carry out the binding work for a long time, the utility model provides a steel wire binding device for a steel bar framework. The technical solution is as follows:
[0004] A steel wire binding device for a steel bar framework includes a square-shaped hand-held frame. A screw rod is threadedly arranged on the bottom plate of the hand-held frame. One end of the screw rod penetrates through the bottom plate of the hand-held frame and is located outside it. A hook is fixedly connected to the end of the screw rod located outside the hand-held frame. Limiting rods are arranged on both sides of the screw rod on the bottom plate of the hand-held frame, and the limiting rods are arranged along the length direction of the screw rod. The upper end of the screw rod is rotatably connected to a T-shaped hand-held rod, and both ends of the cross bar of the hand-held rod are slidably connected to the limiting rods on both sides.
[0005] Further, a spring is sleeved on the limiting rod. One end of the spring is fixedly connected to one end of the cross bar of the hand-held rod, and the other end of the spring is fixedly connected to the inner side surface of the bottom plate of the hand-held frame. The pulling force of the spring can make the hand-held rod automatically reset, facilitating the rotation of binding the steel wire next time.
[0006] Further, the upper end of the screw rod is rotatably connected to the vertical rod of the hand-held rod through a bearing.
[0007] Further, a limiting plate is commonly connected to the upper ends of the limiting rods on both sides, and both ends of the limiting plate are fixedly connected to the inner side walls of the hand-held frame. The limiting plate can avoid the problem of wasting physical strength due to excessive lifting when operating the hand-held rod.
[0008] Further, rings are fixed at both ends of the cross bar of the hand-held rod. The rings are sleeved on the limit rod and fixedly connected to one end of the spring. The rings can ensure that the hand-held rod moves along the limit rod when moving up and down.
[0009] Further, rubber sleeves are provided on the top plate of the hand-held frame and the cross bar of the hand-held rod, which can effectively protect the palm and avoid excessive wear on the hand when using the device.
[0010] The beneficial effects of the technical solution provided by the present utility model are as follows: The device has a simple structure and is convenient and fast to use. By bending the fingers to lift the hand-held rod, not only the problem of palm wear caused by the rotation of the binding device in the palm is avoided, but also the efficiency of wire binding is improved, saving the time cost of construction.

[0014] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the embodiments of the present utility model will be further described in detail below with reference to the drawings.
[0015] See Figure 1 , an embodiment of the present utility model provides a wire binding device for a steel bar framework, including a square hand-held frame 1. A screw rod 2 is threadedly provided on the bottom plate of the hand-held frame 1. One end of the screw rod 2 penetrates through the bottom plate of the hand-held frame 1 and is located outside it. A hook 3 is fixedly connected to the end of the screw rod 2 located outside the hand-held frame 1. Limit rods 5 are provided on both sides of the screw rod 2 on the bottom plate of the hand-held frame 1, and the limit rods 5 are arranged along the length direction of the screw rod 2. The upper end of the screw rod 2 is rotatably connected to a T-shaped hand-held rod 4. Both ends of the cross bar of the hand-held rod 4 are slidably connected to the limit rods 5 on both sides.
[0016] A spring 6 is sleeved on the limit rod 5. One end of the spring 6 is fixedly connected to one end of the cross bar of the hand-held rod 4, and the other end of the spring 6 is fixedly connected to the inner side surface of the bottom plate of the hand-held frame 1.
[0017] The upper end of the screw rod 2 is rotatably connected to the vertical rod of the hand-held rod 4 through a bearing 7.
[0018] The upper ends of the limiting rods 5 on both sides are jointly connected with a limiting plate 8, and both ends of the limiting plate 8 are fixedly connected to the inner side walls of the hand-held frame 1.
