Description

Technical Field

[0001] This utility model relates to the field of rebar tying technology, and in particular to an automatic locking clamp for rebar tying. Background Technology

[0002] Traditional rebar tying relies on workers manually winding wire, which is inefficient, labor-intensive, and produces inconsistent quality. With the expansion of building scale and the increasing demand for standardized construction, automatic locking pliers have emerged, solving both efficiency and quality issues and becoming an important tool in modern mechanized construction.

[0003] The automatic locking clamp works in conjunction with an electronic control system and mechanical structure. It features a built-in unwinding roller with wire inside, which then pushes the wire to the rebar intersection via a wire feeding mechanism. The clamp head wraps the wire around the rebar to form a closed loop, and a rotating module tightens the wire and cuts off any excess. Some models support tension adjustment to ensure consistent binding tightness. Power is primarily provided by battery or AC power, balancing portability and efficiency. The workflow involves aligning the clamp with the rebar intersection and automatically completing four steps: wire feeding, looping, tightening, and cutting. The tool can be used for the next job after resetting, making it suitable for large-scale rebar binding scenarios such as high-rise buildings and bridges.

[0004] In existing technology, an accommodating groove for accommodating the unwinding roller is usually provided near the tail of the automatic locking clamp. U-shaped limiting grooves are provided on the inner walls of both sides of the accommodating groove. The rotating shafts at both ends of the unwinding roller extend into the limiting grooves. The unwinding roller can be restricted during use, but it cannot be restricted along the direction of the unwinding roller being placed into the accommodating groove. When the wire feeding mechanism conveys the wire, the unwinding roller slides, which will affect the accuracy of the wire feeding mechanism in conveying the wire. In addition, the back-and-forth sliding of the unwinding roller during use can also easily generate noise and affect the user experience. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that the unwinding roller is prone to slippage during use, which not only affects the wire feeding accuracy of the wire feeding mechanism, but also generates noise due to the back-and-forth sliding and impact of the unwinding roller. Therefore, an automatic locking clamp for rebar binding is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An automatic locking clamp for tying rebar includes an automatic locking clamp body. One end of the automatic locking clamp body has a receiving groove for placing an unwinding roller. The body also includes a fixed shaft fixedly disposed on the inner wall of one side of the receiving groove. A movable shaft elastically extends and retracts on the inner wall of the other side of the receiving groove. A rotating cylinder is coaxially rotatably disposed on the unwinding roller. Multiple inclined guide plates are fixedly disposed at one end of the fixed shaft and the movable shaft extending into the rotating cylinder, and the inclined surfaces of the inclined guide plates abut against the outer walls of both ends of the rotating cylinder.

[0008] To facilitate the sliding of the movable shaft, preferably, a limiting groove is formed on the inner wall of the other side of the receiving groove, one end of the movable shaft is slidably disposed in the limiting groove, and a first spring is provided in the limiting groove, with the two ends of the first spring abutting against the receiving groove and the movable shaft respectively.

[0009] To facilitate the sliding of the movable shaft, a push plate is slidably provided on the body of the automatic locking clamp. One end of the push plate, which extends into the limiting groove, is fixedly connected to the movable shaft. When the push plate is pushed to slide the movable shaft into the limiting groove, the inclined guide plate moves away from the rotating cylinder.

[0010] In order to protect the contents of the receiving slot, preferably, a protective cover is provided on the receiving slot. One end of the protective cover is rotatably connected to the body of the automatic locking clamp, and the other end of the protective cover is detachably connected to the body of the automatic locking clamp through a locking component.

[0011] Furthermore, the locking component includes a locking plate slidably disposed within the body of the automatic locking clamp, a slot is provided on the inner wall of the other end of the protective cover, one end of the locking plate is engaged with the slot, a guide groove is provided within the body of the automatic locking clamp, a pressing rod is slidably disposed within the guide groove, the other end of the locking plate is fixedly connected to the pressing rod, and a second spring is disposed within the guide groove, with both ends of the second spring abutting against the guide groove and the locking plate respectively.

[0012] Furthermore, the protective cover is made of transparent plastic and is used to observe the condition of the wires on the unwinding roller.

[0013] Compared with the prior art, this utility model provides an automatic locking clamp for rebar tying, which has the following beneficial effects:

[0014] 1. This automatic locking clamp for rebar tying has a fixed shaft fixedly installed on the inner wall of one side of the receiving groove, and a movable shaft that slides elastically on the inner wall of the other side. Both the fixed shaft and the movable shaft are fixedly equipped with inclined guide plates, which can fix the rotating cylinder on the unwinding roller. During use, the sliding or shaking of the unwinding roller is reduced. This not only ensures the wire feeding accuracy of the wire feeding mechanism, but also helps to reduce the noise generated by the impact of the unwinding roller and improve the user experience.

[0015] 2. This automatic locking clamp for rebar tying has a protective cover on the receiving groove, which can protect the receiving groove and the unwinding roller during use, reducing the entry of dust and other contaminants into the receiving groove. Moreover, the protective cover is preferably made of transparent plastic, which allows the condition of the wire on the unwinding roller to be checked, thus improving the usage effect.

[0016] The parts of this device not described herein are the same as or can be implemented using existing technology. This utility model has a fixed shaft fixedly installed on the inner wall of one side of the receiving groove, and a movable shaft elastically sliding on the inner wall of the other side. Inclined guide plates are fixedly installed on both the fixed shaft and the movable shaft, which can fix the rotating cylinder on the unwinding roller. During use, the sliding or shaking of the unwinding roller is reduced, which not only ensures the wire feeding accuracy of the wire feeding mechanism, but also helps to reduce the noise generated by the impact of the unwinding roller and improve the user experience.

[0024] Example:

[0025] Reference Figures 1-4An automatic locking clamp for rebar tying includes an automatic locking clamp body 1. A receiving groove 101 for placing a unwinding roller is provided at one end of the automatic locking clamp body 1. A fixed shaft 3 is fixedly installed on the inner wall of one side of the receiving groove 101, and a movable shaft 301 elastically extends and retracts on the inner wall of the other side of the receiving groove 101. A rotating cylinder is coaxially rotatably mounted on the unwinding roller. Multiple inclined guide plates 302 are fixedly installed at the ends of the fixed shaft 3 and the movable shaft 301 extending into the rotating cylinder. There are two to ten inclined guide plates 302; preferably, three are used. These three are evenly distributed circumferentially, meaning three inclined guide plates 302 are fixedly installed on the fixed shaft 3 and the movable shaft 301 respectively, with the inclined surfaces of the inclined guide plates 302 abutting against the outer walls of both ends of the rotating cylinder. In use, the rotating cylinder on the unwinding roller is fitted onto the fixed shaft 3. On the fixed shaft 3, one end of the rotating cylinder abuts against the inclined guide plate 302 on the fixed shaft 3 and pushes the movable shaft 301 away from the fixed shaft 3. After the unwinding roller is placed in place, the push on the movable shaft 301 is released. Under the action of elasticity, the inclined guide plate 302 on the movable shaft 301 can abut against the other end of the rotating cylinder, thereby fixing the rotating cylinder in the current position. In use, by fixing the fixed shaft 3 on one side of the inner wall of the receiving groove 101 and elastically sliding the movable shaft 301 on the other side of the inner wall, and fixing the inclined guide plate 302 on both the fixed shaft 3 and the movable shaft 301, the rotating cylinder on the unwinding roller can be fixed, reducing the sliding or shaking of the unwinding roller during use. This not only ensures the wire feeding accuracy of the wire feeding mechanism, but also helps to reduce the noise generated by the impact of the unwinding roller and improves the user experience.

[0026] Reference Figure 4 A limiting groove 103 is formed on the inner wall of the other side of the receiving groove 101. One end of the movable shaft 301 is slidably set in the limiting groove 103, and a first spring is set in the limiting groove 103. The two ends of the first spring abut against the receiving groove 101 and the movable shaft 301 respectively. In use, by sliding one end of the movable shaft 301 in the limiting groove 103, the movable shaft 301 can be reliably slid. Moreover, the first spring in the limiting groove 103 not only makes the movable shaft 301 have an elastic sliding effect, but also, under the elastic force of the first spring, makes the inclined guide plate 302 on the movable shaft 301 abut against the other end of the rotating cylinder, thereby fixing the rotating cylinder.

[0027] Reference Figure 4A push plate 303 is slidably mounted on the automatic locking clamp body 1. One end of the push plate 303, extending into the limiting groove 103, is fixedly connected to the movable shaft 301. When the push plate 303 is pushed to slide the movable shaft 301 into the limiting groove 103, the inclined guide plate 302 moves away from the rotating cylinder. At this time, the unwinding roller can be removed. During installation, the push plate 303 is pushed first to push the movable shaft 301 towards the limiting groove 103, and then the unwinding roller is installed. After installation, the push plate 303 is released. Under the elastic force of the first spring, the inclined guide plate 302 on the movable shaft 301 slides towards the rotating cylinder and abuts against it. With the cooperation of the inclined guide plate 302 on the fixed shaft 3, the rotating cylinder can be fixed, improving the usage effect.

[0028] Reference Figures 1-3 A protective cover 2 is provided on the receiving groove 101. One end of the protective cover 2 is rotatably connected to the automatic locking clamp body 1, and the other end of the protective cover 2 is detachably connected to the automatic locking clamp body 1 through a locking member. The protective cover 2 is made of transparent plastic and is used to observe the condition of the wire on the unwinding roller. During use, by providing the protective cover 2 on the receiving groove 101, the receiving groove 101 and the unwinding roller can be protected during use, reducing the entry of dust and other substances into the receiving groove 101. Moreover, the material of the protective cover 2 is preferably transparent plastic, which allows the condition of the wire on the unwinding roller to be viewed, thus improving the usage effect.

[0029] Reference Figure 3 The locking mechanism can be secured to the automatic locking clamp body 1 using bolts, pins, or buckles. Here, the locking mechanism is designed with a sliding locking plate 4 inside the automatic locking clamp body 1. A locking groove 201 is provided on the inner wall of the other end of the protective cover 2, and one end of the locking plate 4 is engaged with the locking groove 201. A guide groove 102 is provided inside the automatic locking clamp body 1, and a pressing rod 401 is slidably provided in the guide groove 102, and the other end of the locking plate 4 is fixedly connected to the pressing rod 401. A second spring is provided in the guide groove 102, and the two ends of the second spring abut against the guide groove 102 and the locking plate 4, respectively. In use, by pressing the pressing rod 401, the locking plate 4 can be pushed away from the protective cover 2, causing the locking plate 4 to disengage from the locking groove 201. At this time, the protective cover 2 can be opened, making it convenient to use.
