Description

Technical Field

[0001] This application relates to the technical field of rebar tying, and in particular to an automatic rebar tying device. Background Technology

[0002] Reinforcing bars are typically steel bars with transverse ribs on their surface. They have high tensile strength and are mainly used in building construction. During the construction process, reinforcing bar binding is a crucial step. Steel wire is wrapped around the lap joints of transverse and axial reinforcing bars and then tightened to fix the reinforcing bars, thus forming a large-area reinforcing mesh.

[0003] Traditional rebar tying methods mainly rely on manual operation, using wire hooks to wrap the wire around the rebar intersections and tighten it. This method is labor-intensive, labor-intensive, and produces inconsistent construction quality. Therefore, some manufacturers use automatic rebar tying devices. By holding the device and aligning the tying head with the rebar intersection, pressing the operation button, the motor drives the transmission mechanism to rotate the tying head around the rebar, wrapping the wire around it. Then, the tying head tightens the wire through a special mechanical structure, completing the rebar tying.

[0004] However, construction sites are complex environments with narrow spaces and densely packed rebar. When workers operate handheld equipment, space constraints and operational complexity make it difficult to keep their hands in a safe position at all times. For example, when a lower layer of rebar is found to be missing and needs to be re-tied, the upper layer of rebar obstructs the view, making it difficult for the human eye to accurately judge the depth of the lower layer and precisely control the distance between the hands / equipment and the upper layer of rebar. This can easily lead to contact between the rebar and the worker's hands, causing hand injuries. Furthermore, the battery is usually installed at the end of the handheld part and protrudes beyond the hand, making it more susceptible to accidental impact with the rebar and damage. To address these issues, we have provided an automatic rebar tying device. Utility Model Content

[0005] To address the problems of existing rebar binding devices that easily lead to hand injuries from contact between rebar and human hands, and the fact that batteries are usually installed at the end of the handheld part and protrude beyond the hand, making them more susceptible to accidental impact and damage to the rebar, this application provides an automatic rebar binding device.

[0006] This application provides an automatic rebar tying device, which adopts the following technical solution: An automatic rebar tying device includes a device body and a handle. The device body is provided with a binding wire, a wire outlet, and a main switch. A wire outlet button is provided on one side of the handle. A protective mechanism is provided on one side of the handle to form a barrier in front of the user's hand, thereby preventing the hand from contacting the rebar. A fixing mechanism is provided at the upper end of the protective mechanism to securely fix the protective mechanism to one side of the handle. A fixing block is fixedly installed at the lower part of the handle. A sliding seat is slidably connected to the inner side of the fixing block. A buffer mechanism is provided at the upper part of the sliding seat. A lithium battery is detachably connected to the lower part of the sliding seat.

[0007] Optionally, the protective mechanism includes a protective plate, with an inner liner fixedly connected to the inner side of the protective plate, and fixing holes provided on the upper part of the protective plate and the inner liner.

[0008] Optionally, the protective plate is made of aluminum alloy, and the inner lining is made of silicone.

[0009] Optionally, the fixing mechanism includes a mounting block, the upper end of which is fixedly mounted on the device body, and a fixing screw is fixedly connected to one side of the mounting block.

[0010] Optionally, the outer surface of the fixing screw is perforated by the protective plate and the inner liner in sequence, and the outer surface of the fixing screw is threaded with screws.

[0011] Optionally, the buffer mechanism includes a long plate, the lower surface of which is fixedly connected to a sliding seat, and a fixing rod fixedly connected to one side of the long plate, the outer surface of which is slidably connected to a fixing block.

[0012] Optionally, a spring is fitted onto the outer surface of the fixing rod, one end of the spring is fixedly connected to the long plate, and the other end of the spring is fixedly connected to the fixing block.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] 1. This utility model, by setting up a protective mechanism and a sliding seat, ensures that during use, the protective mechanism first contacts the first layer of steel reinforcement to protect the hand from contact with the steel reinforcement, thus preventing hand injury. At the same time, the sliding seat can slide relative to the fixed block, so that when the lithium battery collides with an object in front, the lithium battery and the sliding seat can move backward, thus preventing the lithium battery from a hard collision with the object and avoiding battery damage. This solves the problems of existing designs that easily lead to contact between the steel reinforcement and the hand, causing hand injury, and the fact that the battery is usually installed at the end of the hand-held part and protrudes beyond the hand, making it more susceptible to accidental impact with the steel reinforcement and damage.

[0015] 2. This utility model, by incorporating components such as a buffer mechanism, ensures that when a lithium battery accidentally collides with a steel bar or other object during operation, the impact force pushes the lithium battery toward the inward side of the device, causing the sliding seat to slide backward along the inner slide rail of the fixed block. As the sliding seat slides, the spring between the long plate and the fixed block is compressed, and the reverse elastic force generated by the spring gradually dissipates the kinetic energy generated by the impact, transforming the hard collision of the lithium battery into a flexible contact process of sliding buffer, thus preventing the lithium battery casing from cracking or internal components from being damaged due to instantaneous impact.

[0022] The following is in conjunction with the appendix Figure 1-5 The accompanying drawings provide a further detailed description of this application. The technical solutions in the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0023] This application discloses an automatic rebar tying device. For example... Figure 1As shown, an automatic rebar tying device includes a device body 1 and a handle 2. The device body 1 is provided with a binding wire 11, a wire outlet 12, and a main switch 13. A wire outlet button 10 is provided on one side of the handle 2, and a protective mechanism 3 is provided on one side of the handle 2. The protective mechanism 3 is used to form a barrier in front of the user's hand to prevent the hand from contacting the rebar. A fixing mechanism 4 is provided at the upper end of the protective mechanism 3 to securely fix the protective mechanism 3 to one side of the handle 2. A fixing block 5 is fixedly installed at the lower part of the handle 2, and the inner side of the fixing block 5... A sliding seat 6 is slidably connected, and a buffer mechanism 7 is provided on the upper part of the sliding seat 6. A lithium battery 8 is detachably connected to the lower part of the sliding seat 6. The tying wire 11, the cable outlet 12, and the main switch 13 on the device body 1 are all components in existing devices, and this application has not improved them. The improvement lies in the provision of a protective mechanism 3 on the front side of the handle 2. When in use, the fingers grasp the handle 2, so that the fingers are located behind the protective mechanism 3. When in use, the cable outlet 12 is inserted from the gap of the steel bar to the bottom, locking the position where the second layer of steel bar needs to be tied. Pressing the button... When the button 10 is activated, its protective mechanism 3 first contacts the first-floor steel reinforcement to protect the hand from contact with the reinforcement, thus preventing hand injury. Simultaneously, the sliding seat 6 can slide relative to the fixed block 5, allowing the lithium battery 8 and the sliding seat 6 to move backward when the lithium battery 8 collides with an object in front, preventing a hard impact and thus avoiding battery damage. The lithium battery 8 supplies power to the device body 1 via a connecting cable 9, with plugs at both ends. One plug connects to the charging connector on the sliding seat 6. One end of the connector is connected to the power input interface of the main body 1. When the lithium battery 8 is installed, the power is transmitted through the charging interface on the sliding base 6. The connecting wire 9 can be bent, so that the power supply remains stable when the lithium battery 8 is moving. Both ends of the connecting wire 9 are sealed. The lower part of the sliding base 6 is provided with a spring buckle, and the outer shell of the lithium battery 8 is provided with a corresponding slot. During installation, align the lithium battery 8 with the lower part of the sliding base 6 and press it firmly. The buckle will then snap into the slot to achieve fixation. This is a commonly used snap-fit ​​method in the prior art, and will not be described in detail here.

[0024] Please see Figure 5 The protective mechanism 3 includes a protective plate 301, with an inner liner 302 fixedly connected to the inner side of the protective plate 301. Fixing holes 303 are provided on the upper part of the protective plate 301 and the inner liner 302. The protective plate 301 is made of aluminum alloy, and the inner liner 302 is made of silicone. Aluminum alloy has a high strength-to-weight ratio, ensuring that the protective plate 301 has sufficient strength to resist the impact of steel bars while being relatively lightweight, thus not adding too much burden to the operator and facilitating long-term hand operation. The silicone material is very skin-friendly, with low skin irritation, suitable for long-term contact with the hands, and also increases the tactile feel of the hands.

[0025] Please see Figure 5 The fixing mechanism 4 includes a mounting block 401. The upper end of the mounting block 401 is fixedly mounted on the device body 1. A fixing screw 402 is fixedly connected to one side of the mounting block 401. The outer surface of the fixing screw 402 passes through the protective plate 301 and the inner liner 302 in sequence. The outer surface of the fixing screw 402 is threaded with screws. The protective plate 301 is fixed by the screws and the fixing screw 402 so that the protective plate 301 can protect the hand.

[0026] Please see Figure 3 The buffer mechanism 7 includes a long plate 701, the lower surface of which is fixedly connected to the sliding seat 6. A fixing rod 702 is fixedly connected to one side of the long plate 701. The outer surface of the fixing rod 702 is slidably connected to the fixing block 5. The fixing rod 702 restricts the fixing block 5, thereby preventing the sliding seat 6 from tilting or shifting from the fixing block 5, so that the sliding seat 6 can move smoothly.

[0027] Please see Figure 3 A spring 703 is sleeved on the outer surface of the fixing rod 702. One end of the spring 703 is fixedly connected to the long plate 701, and the other end of the spring 703 is fixedly connected to the fixing block 5. The spring 703 buffers the sliding seat 6 when it slides, so as to further reduce the damage to the battery 8.

[0028] The implementation principle of the automatic rebar tying device in this application embodiment is as follows: The operator holds the handle 2 with their hand, and their fingers are naturally behind the protective mechanism 3. The protective plate 301 and the inner lining 302 form a hand protection area. When it is necessary to re-tie the lower layer of rebar, the operator inserts the device's outlet 12 downward from the gap of the upper layer of rebar and aligns it with the tying node of the second layer of rebar. The protective plate 301 will preferentially contact the upper layer of rebar, forming a physical barrier and separating the hand from the rebar. Throughout the tying process, the protective mechanism 3 is always in front of the hand and maintains a stable position with the help of the rigid connection of the fixing mechanism 4. No matter how the outlet 12 is adjusted, it can continuously block the direct collision of the rebar with the hand, thus physically cutting off the path of hand injury.

[0029] When the lithium battery 8 accidentally collides with a steel bar or other object during operation, the impact force pushes the lithium battery 8 inward, causing the sliding seat 6 to slide backward along the inner rail of the fixed block 5. As the sliding seat 6 slides, the spring 703 between the long plate 701 and the fixed block 5 is compressed. The counter-elastic force generated by the spring 703 gradually dissipates the kinetic energy generated by the impact, transforming the hard impact of the lithium battery 8 into a flexible contact process of sliding buffer, preventing the lithium battery 8's casing from cracking or its internal components from being damaged by the instantaneous impact. After the collision, the restoring force of the spring 703 can push the sliding seat 6 and the lithium battery 8 back to their initial positions, without affecting subsequent operations.

[0030] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
