Detailed Implementation

[0029] The embodiments of this utility model will be described in more detail below with reference to the accompanying drawings and reference numerals, so that those skilled in the art can implement them after reading this specification. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0030] This utility model provides a foot-operated rebar tying device, including a column 11, a first sleeve 21 that slides relative to the column 11 and can be locked, a base 22 disposed on the first sleeve 21, a second sleeve 31 that slides relative to the first sleeve 21, and a nailing device disposed on the second sleeve 31.

[0031] Please refer to Figure 1-2 The first sleeve 21 is slidably connected to the column 11. The first sleeve 21 is also provided with a stop device for locking the column 11 and the first sleeve 21. A base 22 is provided at the bottom of the first sleeve 21. When the column 11 is placed vertically, the height of the base 22 can be adjusted through the first sleeve 21, and the positions of the first sleeve 21 and the base 22 are fixed by the stop device.

[0032] Please refer to Figure 3In this embodiment, the stopping device includes a ratchet rack 12 disposed on one side of the column 11, the ratchet rack 12 extending parallel to the column 11. A pawl 24, which engages with the ratchet rack 12, is slidably connected to the first sleeve 21. A third compression spring 25 is also disposed between the pawl 24 and the first sleeve 21. The pawl 24 is further provided with a connecting rod 26 that slides relative to the first sleeve 21. The connecting rod 26 protrudes from the first sleeve 21 and is provided with a paddle 27. When the third compression spring 25 resets, its elastic force pushes the pawl 24 until it engages with the ratchet rack 12, preventing the first sleeve 21 from moving downwards relative to the column 11, thus achieving a one-way stopping effect. When adjusting the height of the base 22, the paddle 27 needs to be pulled outwards to disengage the pawl 24 from the ratchet rack 12.

[0033] In other embodiments, the stopping device may also adopt other existing structures, such as having multiple pin holes equidistantly arranged along the length of the column 11, with a pin slidably connected to the first sleeve 21, and the stopping is completed by inserting the pin into the pin hole.

[0034] Further, please refer to Figure 4 The column 11 includes a main body 111 and two wing plates 112 disposed on both sides of the main body 111. The main body 111 and the two wing plates 112 are connected in a Y-shape. The ratchet 12 is disposed between the two wing plates 112 and does not protrude from the column 11 to prevent damage to the ratchet 12 from impacts. The first sleeve 21 and the second sleeve 31 are both triangular prisms. The three protruding parts of the column 11 correspond to the three inner corners of the first sleeve 21, which serve as a limiting function to prevent the relative rotation of the column 11 and the first sleeve 21 from causing misalignment between the ratchet 12 and the pawl 24.

[0035] The first sleeve 21 is also slidably connected to the second sleeve 31, and a first compression spring 32 is provided between the second sleeve 31 and the base 22. The second sleeve 31 is connected to the nail-down device, and the nail-down device can be pushed towards the base 22 through the second sleeve 31 and reset by the first compression spring 32.

[0036] Please refer to Figure 5-6 The nail-down device is located above the base 22 and includes a housing 41 connected to the second sleeve 31. The housing 41 is provided with a sliding groove 42, and a guide rail 46 is also provided on one side of the housing 41. A binding nail strap 50 is slidably connected to the guide rail 46. The housing 41 is also provided with a nail inlet 47 communicating with the sliding groove 42, which allows the binding nail strap 50 on the guide rail 46 to be pushed into the sliding groove 42 from the nail inlet 47. The guide rail 46 can extend in an arc or a straight line. In this embodiment, the guide rail is arc-shaped, and one end of it is provided with a horizontal extension, which is connected to the housing. In other embodiments, the guide rail can also extend in a straight line.

[0037] A sliding groove 42 is slidably connected to a pressure tongue 43. The pressure tongue 43 is equipped with a pedal 44, and a second compression spring 45 is provided between the pedal 44 and the housing 41. When the operator steps on the pedal 44, the nail-feeding device moves towards the base 22, and the pressure tongue 43 is pressed down. The binding nail 51 in the sliding groove 42 is disengaged from the binding nail band 50 and squeezed out from the lower outlet of the sliding groove 42. After the downward pressure is released, the elastic force of the second compression spring 45 resets the pressure tongue 43, returning it to above the nail inlet 47. Preferably, the stiffness of the first compression spring 32 is less than that of the second compression spring 45. When the pedal 44 is pressed down, the nail-feeding device will first move down until it is blocked, and then the pressure tongue 43 will press down to push the binding nail 51 to move.

[0038] Please refer to Figure 7 The base 22 is also provided with a pair of guide grooves 23 corresponding to the slide groove 42. The two ends of the binding nail 51 slide into the pair of guide grooves 23 respectively, and under the action of pressure, they bend towards each other along the smooth curved surface of the bottom of the guide groove 23 to complete the binding action.

[0039] Furthermore, the guide rail 46 is also provided with a staple feeding device for pushing the staple tape 50 into the slide groove 42. The staple feeding device includes a top sleeve 461 that slides relative to the guide rail 46, and a tension spring 462 is provided between the top sleeve 461 and the housing 41, using the elastic force of the tension spring 462 to compress the staple tape 50. The guide rail 46 is also provided with a limiting groove 463 for accommodating the tension spring 462.

[0040] Please refer to Figure 8-10 The binding tape 50 has a structure similar to staple tape, comprising multiple stacked U-shaped or C-shaped binding studs 51, which are fitted onto the top of the guide rail 46 during use. The two types of binding studs have the same width but different lengths; the C-shaped binding studs are shorter and used for binding rebars with diameters of 6, 8, 10, and 12 mm, while the U-shaped binding studs are longer and used for binding rebars with diameters of 14, 16, 18, and 20 mm. A connecting portion 511 is located in the middle of each binding stud 51. Adhesive is applied to the connecting portion 511 to bond multiple binding studs 51 sequentially into a strip shape, allowing the binding tape 50 to be unfolded as follows: Figure 8 The shape shown is adapted to fit the curved guide rail 46.

[0041] In use, the base 22 is first placed on top of the intersection of the longitudinal and transverse reinforcing bars, and the column 11 is pressed down to the bottom formwork of the area to be poured. Due to the limitation of the stop device, the base 22 cannot move downward relative to the column 11. Then, the column 11 is tilted, and the base 22 is inserted obliquely to the bottom of the intersection of the longitudinal and transverse reinforcing bars. The foot pedal 44 is used to bring the nailing device close to the top of the intersection of the longitudinal and transverse reinforcing bars. The nailing device and the base 22 clamp the intersection of the reinforcing bars in the middle, and the pressure tongue 43 is used to push the binding nail 51 in the slide groove 42 toward the reinforcing bar. After the two ends of the binding nail 51 come into contact with the base 22, they are guided by the smooth curved surface of the bottom of the guide groove 23 to bend toward each other, completing the binding action of the intersection of the reinforcing bars. The binding process is similar to the working principle of a stapler. After binding is completed, the foot pedal 44 is released, and the nailing device and the foot pedal 44 are reset.

[0042] The above describes one or more embodiments of this utility model in a relatively specific and detailed manner, but it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
