Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically a novel fully manual rebar tying device. Background Technology

[0002] Reinforcing bar binding is a crucial part of construction engineering, and its quality directly affects the stability and safety of the overall structure.

[0003] Current rebar tying is typically done manually, which is labor-intensive, inefficient, and costly. Especially when working at heights, workers need to use both hands—one to hold the tying nail and the other to rotate the hook—to complete the task, posing certain safety hazards. Although electric rebar tying machines exist, their reliability, practicality, battery life, and price have limited application. Furthermore, the machines' weight makes them unsuitable for carrying at heights. Therefore, a convenient, compact, and easy-to-operate tool for tying rebar is needed, hence the requirement for this new type of fully manual rebar tying device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a novel fully manual rebar tying device, which solves the technical problems mentioned in the background section.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a novel fully manual rebar tying device, comprising a main column and a guide rail, wherein the guide rail is divided into upper and lower ends, an auxiliary reset mechanism is installed between the upper end of the guide rail and the main column, a tying mechanism is installed at the lower end of the guide rail, and a linkage component is installed on the guide rail;

[0006] The binding mechanism includes a pair of gate heads, which are installed at the lower end of the guide rail. The main column is movably inserted into the gate head. The gate head has a first through hole for placing the main column. A pair of baffles are installed inside the gate head. Binding auxiliary components are installed at both ends of the guide rail near the first through hole.

[0007] Preferably, the binding auxiliary component includes a flange, which is installed on both sides of the outer wall of the guide rail. An iron dragonfly is installed on the guide rail near the baffle. The iron dragonfly includes dragonfly wings and a dragonfly head. A first tension spring is installed at the other end of the dragonfly head.

[0008] Preferably, a shaft stop is installed on the outer wall of the rotating shaft, the lower end of the rotating shaft near the shaft stop is twisted into a spiral shape, the rotating shaft is movably inserted into the main column and the main column is located inside the first through hole of the gate head, a hook is installed at the end of the rotating shaft near the first through hole, a main column plug is installed on the shaft stop, a rectangular flat hole is opened in the center of the main column plug, a handrail is installed at the upper end of the main column, a compression spring is installed between the handrail and the guide rail, and the main column plug is installed inside the main column.

[0009] Preferably, the linkage component includes wire-pulling rings, a pair of wire-pulling rings are mounted on a guide rail, a pair of spring grooves are provided on the outer side of the guide rail, a second tension spring is installed inside the pair of spring grooves, and one end of the second tension spring is connected to the wire-pulling ring.

[0010] Preferably, the guide rail contains binding wire, and the lower end of the binding wire is a reinforcing bar to be bound.

[0011] Beneficial effects

[0012] This utility model provides a novel fully manual rebar tying device, which has the following advantages:

[0013] High-efficiency automated tying

[0014] Through the coordinated design of the elliptical guide rail and the gate head, combined with the deformation characteristics of the elastic binding wire, the binding wire automatically expands from an O-shape to a C-shape and springs back to close. Combined with the linkage mechanism of the rotating shaft twisting into a spiral shape and the hook claw, the entire process of rebar winding and knotting is automated, improving efficiency by 3 to 5 times compared to traditional manual binding.

[0015] Stable and reliable binding quality

[0016] The binding wire is pre-formed from elastic material and is constrained by both the elliptical flange of the gate head section and the outer circular tube during the pushing process, ensuring that the deformation process is controllable. The iron dragonfly's wings keep the binding wire in a C-shaped expanded state, preventing the binding wire from closing prematurely. The synchronous rotation design of the hook and the rotating shaft ensures uniform knotting force and consistent number of wrapping turns, effectively preventing loosening.

[0017] The main column's inner tube plug and the rotating shaft's rectangular flat iron, twisted into a spiral shape, are designed to adapt to complex working conditions, enabling precise conversion between downward pressure and rotational torque. It is compatible with the cross-tying of reinforcing bars of different specifications up to 20mm in diameter, making it particularly suitable for operation in confined spaces with dense reinforcing bars.

[0018] Improved ease of use

[0019] The linear push structure (replacing the pressure handle with linear motion) and the separate base design, which mimic the principle of a stapler, break through the stroke limitations of traditional rotating arms. The operator only needs to press the main column downwards once to complete the entire process of feeding wire, expanding, winding, and knotting, reducing reliance on the operator's skill level.

[0020] Structural durability and maintainability

[0021] The elliptical guide rail adopts a split flange structure to reduce frictional loss of the binding wire; the rotating shaft and hook are integrally welded from solid steel, improving torsional strength. The device is equipped with a dual reset system of tension and compression springs, and key moving parts are not electrically dependent, making it suitable for harsh construction site environments.

[0036] In this embodiment, the auxiliary reset mechanism is further configured such that the rotating shaft (20) is a rectangular flat iron with a shaft stop (203) installed on its side. The lower end of the rotating shaft (20) near the shaft stop (203) is twisted into a spiral shape (201). The rotating shaft (20) is movably inserted into the main column (10) and the main column (10) is located inside the first through hole of the guide rail (30).

[0037] In this embodiment, the linkage component is further configured such that the linkage component includes a wire-pushing ring (304), a pair of wire-pushing rings (304) are mounted on a guide rail (30), a pair of spring grooves (302) are provided on the outer side wall of the guide rail (30), a second tension spring (303) is installed inside the pair of spring grooves (302), and one end of the second tension spring (303) is connected to the wire-pushing ring (304).

[0038] In this embodiment, the guide rail (30) is further configured to have a binding wire (60) placed inside.

[0039] Its detailed connection method is a well-known technology in this field. The following mainly introduces the working principle and process, and the specific work is as follows.

[0040] Example:

[0041] This solution has the following technical features:

[0042] Binding wire: Factory-customized adhesive-coated integrated binding wire material has a certain degree of elasticity. The initial shape of the binding wire is an open O-shape, with both ends of the opening bent into hooks. It is installed on the guide rail and gradually expands into a C-shape through the flange during the pushing process. The binding wire has the elasticity to return to its original shape. When the binding wire is pushed out of the gate head, it quickly rebounds into an O-shape and wraps around the steel bar with double hooks to close.

[0043] The binding wire pushing device includes a guide rail and a gate head. The guide rail has an elliptical cross-section. The O-shaped binding wire is installed on the guide rail with its open end facing outward. The guide rail is equipped with a binding wire pushing ring and a second tension spring to fix and push the binding wire. The gate head is composed of an elliptical tube and a circular tube. The binding wire is confined between the outer circle and the inner ellipse. The elliptical sidewall is provided with symmetrical flanges. During the process of pushing the binding wire, the flanges expand the binding wire from an O-shape to a C-shape.

[0044] Main column: a hollow rectangular tube with a tube plug inside. A rectangular flat hole is set in the center of the tube plug. The main column is pushed downward, and the binding wire is pushed out from the gate head through the first through hole.

[0045] Rotating shaft: The cross-section is a rectangular flat iron that is partially twisted into a spiral shape. It is inserted into the cavity of the main column. The upper end is free, and the middle part passes through the rectangular flat hole on the main column tube plug. The lower end is connected to the hook. When the main column moves downward, the tube plug moves downward along the main column. The flat hole of the tube plug cooperates with the spiral groove of the main shaft to drive the rotating shaft to rotate.

[0046] Hook: A solid round steel plate welded to the bottom of the rotating shaft. The circumference is provided with upward barbs. The barbs face the same direction. When rotating in the same direction, it hooks and wraps around the binding wire. When rotating in the opposite direction, it disengages from the binding wire.

[0047] Iron Dragonfly: Installed at the bottom of the gate head, the binding wire is pushed away from the guide rail and waits to be pushed to the steel bar. The dragonfly's wings maintain the C-shaped expansion of the binding wire. When the binding bar is pushed down to the steel bar, the dragonfly's head sends the binding wire end into the hook claw.

[0048] Binding wire installation: Install the shaped O-ring binding wire on the elliptical wire gate with the opening facing outward. The tension spring moves the push ring to the end of the integrated binding wire and presses the binding wire tight.

[0049] Binding wire pushing process: The binding wire pushing ring pushes the binding wire along the guide rail towards the gate head. When it enters the gate head, there are flanges on both sides of the elliptical guide rail. The bottom open end of the binding wire is pushed into the upper surface of the flange. Due to the restriction of the outer circle and the inner ellipse, the binding wire expands from O to C shape. When the binding wire is pushed out of the guide rail and waits for the main column to press down, it is restricted by the iron dragonfly's wings and maintains the C-shaped expansion shape.

[0050] Reinforcing steel tying:

[0051] The rebar tying device is placed on the rebar surface, the main column is aligned with the intersection of the two rebars, and the main column is pushed downwards. The tying wire is pushed out from the gate head and moves downwards with the main column.

[0052] When the binding wire head comes into contact with the dragonfly head, the binding wire head is pushed to the hook claw.

[0053] As the binding wire contacts the dragonfly head, the rotating shaft begins to rotate, and the hooks cause the binding wire to knot, tightly binding the steel bar.

[0054] End of rebar binding: When the rebar is observed to be tightly bound or the rotating shaft stops rotating, stop pushing the main column, the compression spring returns the main column to its original position, at which point the rotating shaft rotates in the opposite direction, and the binding wire disengages from the hook.
