[0004] Therefore, it is necessary to design a building steel bar fast binding device. UTILITY MODEL CONTENT

[0005] In order to overcome the shortcomings that traditional steel bar binding mode mainly relies on manual operation using binding wire and binding hook, this mode is not only inefficient, and the labor intensity of worker is great, and it is difficult to guarantee the consistency and firmness of binding, the utility model provides a building steel bar fast binding device.

[0006] The technical implementation scheme of the utility model is as follows: a building steel bar fast binding device, including gun body, push rod, elastic member, muzzle, fixed plate, motor, gear ring, pinion and limit ring, the right side of the inside of gun body is slidably connected with push rod, and the push rod is connected with the gun body and is connected with elastic member, the left side of the outside of gun body is fixedly connected with limit ring, the bottom of gun body is installed with motor, and the output shaft of motor is connected with pinion, the output shaft of motor penetrates limit ring and is rotatably connected with it, the left side of limit ring is rotatably connected with gear ring, and pinion and gear ring are meshed with each other, the upper and lower ends of gear ring are fixedly connected with the fixed plate of symmetrical distribution, the two fixed plates are fixedly connected with muzzle, and gun body and muzzle are rotatably contacted.

[0020] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0021] Example: A rapid rebar tying device for construction, such as Figures 1-5As shown, the device includes a gun body 1, a push rod 4, an elastic element 5, a muzzle 9, a fixing plate 91, a motor 10, a gear ring 11, a pinion 12, and a limiting ring 13. The gun body 1 is made of high-strength aluminum alloy, which has the advantages of being lightweight, high-strength, and corrosion-resistant. It can reduce the overall weight of the device while ensuring its structural stability, making it convenient for construction personnel to operate. It is also not prone to rust and damage in complex construction environments. The push rod 4 is slidably connected to the right side inside the gun body 1. The elastic element 5 is connected between the push rod 4 and the gun body 1. The limiting ring 13 is welded to the left side outside the gun body 1. The motor 10 is installed at the bottom of the gun body 1. The pinion 12 is connected to the output shaft of the motor 10. The output shaft of the motor 10 passes through the limiting ring 13 and is rotatably connected to it. The gear ring 11 is rotatably connected to the left side of the limiting ring 13. The pinion 12 meshes with the gear ring 11. The upper and lower ends of the gear ring 11 are fixedly connected to symmetrically distributed fixing plates 91. The muzzle 9 is fixedly connected between the two fixing plates 91. The gun body 1 and the muzzle 9 are in rotatable contact.

[0022] like Figures 1-4 As shown, it also includes a placement frame 2, a contact plate 3, a rack 6, and a one-way gear 7. The placement frame 2 is slidably connected to the top of the gun body 1. The contact plate 3 is welded to the right rear end of the placement frame 2. The rack 6 is welded to the right end of the push rod 4. The one-way gear 7 is rotatably connected to the rear side of the placement frame 2. The contact plate 3 and the one-way gear 7 mesh with each other, and the rack 6 and the one-way gear 7 mesh with each other, which can realize automatic feeding and provide convenience for the next binding.

[0023] like Figures 1-4 As shown, it also includes guide blocks 8 and hooks 92. Two guide blocks 8 are welded to the rear side of the gun body 1. The rack 6 is slidably connected to the guide blocks 8 to ensure that the rack 6 slides in the correct direction. A hook 92 is welded to the top left side of the muzzle 9 to make the wire more stable during the binding process.

[0024] When it is necessary to tie the rebar, first place the tying wire and other materials into the placement frame 2. Two or three wires will fall into the gun body 1 through the placement frame 2 for easy access. Then, align the gun muzzle 9 with the rebar to be tied, push the push rod 4 to move to the left inside the gun body 1, stretching the elastic element 5. The push rod 4 pushes the wire to the left inside the gun body 1 until it extends out of the gun muzzle 9. Then, wrap one end of the wire extending out of the gun muzzle 9 around the rebar and place it on the hook 92. Start the motor 10. The output shaft of the motor 10 rotates, driving the pinion 12 to rotate. The rotation of the pinion 12 drives the gear ring 11 to rotate on the limit ring 13. The rotation of the gear ring 11 drives the gun muzzle 9 to rotate through the fixing plate 91, so that the wire wraps around the rebar. The wire is wrapped around the rebar to achieve the binding operation. After binding is completed, the motor 10 can be turned off to release the force applied to the push rod 4. The push rod 4 slides to the right and resets under the action of the elastic element 5. The elastic element 5 returns to its original state. At this time, the rack 6 slides to the right on the guide block 8. The guide block 8 can ensure that the rack 6 slides in the correct direction, thereby driving the one-way gear 7 to rotate. The rotation of the one-way gear 7 causes the placement frame 2 to slide on the gun body 1 by lifting the contact plate 3. The wire in the placement frame 2 falls into the gun body 1 under its action and gravity, realizing automatic feeding and facilitating the next binding. The above steps can be repeated to continue to quickly bind other rebars, thereby completing the binding work of the rebar.

[0025] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of this invention. Therefore, the scope of this invention should be limited only by the appended claims.
