Description

Technical Field

[0001] This utility model relates to the technical field of building rebar tying tools, specifically a portable building rebar tying tool. Background Technology

[0002] Reinforcing steel bars are steel materials used in reinforced concrete structures, primarily to enhance structural strength and stability. Reinforcing steel bars are classified by steel type: non-alloy steel bars, low-alloy steel bars, and alloy steel bars. They are also classified by production process: hot-rolled bars, heat-treated bars, residual heat-treated bars, and cold-rolled bars. Finally, they are classified by shape: plain round bars and deformed bars. During use, reinforcing steel bars require binding tools and tying wire to secure them.

[0003] Currently, most existing methods of tying building rebar involve workers manually rotating the binding wire. However, prolonged tying can cause worker fatigue, is inefficient, and results in inconsistent tying strength and rotation counts among workers, leading to varying quality. Over time, this can result in substandard quality rebar tying. Therefore, a portable rebar tying tool is proposed. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please refer to Figure 1 - Figure 6 This utility model provides a technical solution: a portable building rebar tying tool, including a support frame 1; The handle 2 is fixedly connected to the top surface of the support frame 1; And a shock-absorbing pad 3 fixedly connected to the bottom surface of the support frame 1; a binding assembly 40 is provided on the inner side of the support frame 1. The bottom surface of the support frame 1 has a through slot, and an adjustment component 41 is installed inside the slot.

[0017] The binding assembly 40 includes a mounting frame 402 located inside the support frame 1. A first motor 401 is fixedly connected to the top surface of the support frame 1. The bottom end of the output rod of the first motor 401 extends through the top surface of the support frame 1 to the inside of the support frame 1. The bottom end of the output rod of the first motor 401 is fixedly connected to the top surface of the mounting frame 402. A double-threaded rod 404 is provided inside the mounting frame 402. A second motor 403 is fixedly connected to the rear side of the mounting frame 402. The front end of the output rod of the second motor 403 extends through the rear side of the mounting frame 402 to the inside of the mounting frame 402. Bevel gears 405 are fixedly fitted on the surface of the output rod of the second motor 403 and the surface of the double-threaded rod 404. The two bevel gears 405 mesh at an angle. Two T-blocks 406 are provided below the mounting frame 402. The top ends of the two T-blocks 406 slide through the bottom surface of the mounting frame 402 to the inside of the mounting frame 402. The left end of the double-threaded rod 404 is threaded through the right side of the two T-blocks 406. Extending to the left side of the two T-blocks 406, the left and right ends of the double-ended threaded rod 404 are rotatably connected to the inner side of the mounting frame 402 via bearing seats. A connecting block 407 and a connecting clamp 408 are provided below each of the two T-blocks 406. The upper and lower ends of the connecting block 407 are fixedly connected to the bottom surface of the T-block 406 and the top surface of the connecting clamp 408, respectively. Through the binding assembly 40, the second motor 403 drives the bevel gear 405 to rotate the double-ended threaded rod 404, causing the two T-blocks 406 to move synchronously towards each other, precisely controlling the tightening action at both ends of the binding wire. The first motor 401 drives the mounting frame 402 to rotate as a whole, completing the twisting and binding of the binding wire, significantly improving binding efficiency and avoiding manual fatigue. It is especially suitable for large-scale rebar binding scenarios. Mechanical control of the binding wire tightening force and rotation number eliminates individual differences in manual operation, ensuring consistent tightness and twisting number of each binding, greatly improving the pass rate and structural safety of rebar node binding.

[0018] Two T-shaped blocks 406 are symmetrically arranged, and two connecting clips 408 are arranged one in front of the other. The sliding through design of the T-shaped blocks 406 and the mounting frame 402 ensures the stability of movement.

[0019] Both connecting clamps 408 are provided with threaded rods 409 on opposite sides. The threaded rods 409 extend through the side of the connecting clamps 408 to the inside of the connecting clamps 408. The end face of the threaded rods 409 is fixedly connected to a clamping plate 4010. The connecting clamps 408 are equipped with adjustable threaded rods 409 and clamping plates 4010. Different diameter binding wires can be adapted by rotating the threaded rods.

[0020] Friction pads 4011 are fixedly connected to the sides of the clamp 4010 and the inner side of the connecting clamp 408. The friction pads 4011 (rubber or textured surface) enhance the clamping stability and prevent the binding wires from slipping during the binding process.

[0021] Example 2: Based on Example 1, a preferred embodiment of the portable rebar tying tool provided by this utility model is as follows: Figure 1 - Figure 3 and Figure 6 As shown: The adjustment assembly 41 includes an electric push rod 411 and an adjustment plate 412 located inside the slot. The top surface of the electric push rod 411 is fixedly connected to the top surface inside the slot, and the bottom end of the output rod of the electric push rod 411 is fixedly connected to the bottom surface of the adjustment plate 412. The side of the adjustment plate 412 is slidably connected to the side of the slot. A caster wheel 413 is fixedly connected to the bottom surface of the adjustment plate 412. The adjustment assembly 41 is used to control the raising and lowering of the adjustment plate 412 by the electric push rod 411. When moving, the caster wheel 413 is lowered to facilitate pushing. When working, the caster wheel 413 is raised, and the shock-absorbing pad 3 provides stable support to prevent the equipment from sliding. At the same time, the level 5 monitors the horizontal status of the equipment in real time to ensure accurate binding angle and reduce rework.

[0022] A level 5 is fixedly installed on the front of the support frame 1.

[0023] When in use, when movement is required, the electric push rod 411 is activated. The output rod of the electric push rod 411 extends and drives the connected adjustment plate 412 to move downward, thereby causing the adjustment plate 412 to drive the caster wheel 413 to move downward and slide out of the slot. Observe the level 5. Then the caster wheel 413 on both sides moves to the same height, which makes it easy to move the support frame 1. The binding wire is threaded through the reinforcing steel. When the reinforcing steel needs to be tied, the two ends of the binding wire are placed into the two connecting clamps 408 respectively. The threaded rod 409 is rotated, which drives the clamping plate 4010 to move. The clamping plate 4010 drives the friction pad 4011 to clamp and fix the binding wire. The second motor 403 is turned on, and the bevel gear 405 connected to the output rod of the second motor 403 rotates. Through the meshing transmission of the two bevel gears 405, the double-headed threaded rod 404 rotates, which causes the two T-blocks 406 to move closer to each other. In turn, the two connecting clamps 408 drive the two ends of the binding wire to move closer to each other. The first motor 401 is turned on, and the output rod of the first motor 401 drives the mounting frame 402 to rotate, so that the binding wire rotates and the reinforcing steel is tied.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
