Description

Technical Field

[0001] The utility model relates to the technical field of construction tools, in particular to a hook for quickly tying steel wires of steel bars. Background Technique

[0002] At present, China's construction industry is booming. As the mainstream structure of modern buildings, the reinforced concrete structure requires the steel bars inside the structure to be tied according to specifications. The tying of the internal steel bar structure of reinforced concrete is usually manually carried out by construction workers with the help of tools such as steel bar hooks. When tying steel bars, construction workers need to use tools such as hooks to hook the steel bar tying wire and rotate the tying wire. When performing the tying operation, construction workers need to continuously use tools for manual rotation to complete the tying action to ensure that the tying wire is wound tightly. This traditional tying method not only has a large workload, low tying efficiency, high working intensity, but also is easy to cause damage to the wrists of construction workers.

[0003] Patent document CN108678387A discloses a tying tool. By setting a spiral track on the screw rod, an auxiliary steel ball is embedded in the sleeve, and the auxiliary steel ball is slidably connected with the spiral track. The hook body hooks the tying wire, the sleeve is pulled, and the auxiliary steel column moves in the spiral track, forcing the screw rod to rotate, so as to solve the problem of low working efficiency due to the need for manual rotation of the tying wire.

[0004] However, the above structure has the problems that it cannot adapt to the working postures of employees of different heights, increases the burden on the waist of the operators, and when the tying is not firm enough at one time, it is necessary to remove the hook and reset it, and then repeat the operation. Content of the Utility Model

[0005] The purpose of the utility model is to provide one, so as to solve the problems in the prior art that it cannot adapt to the working postures of employees of different heights, increases the burden on the waist of the operators, and when the tying is not firm enough at one time, it is necessary to remove the hook and reset it, and then repeat the operation.

[0006] To achieve the above purpose, the basic scheme provided by the utility model is: a hook for quickly tying steel bars, including a hook body and a screw rod. The hook body is threadedly connected with the screw rod. A spiral track is provided on the screw rod. The spiral track is in the shape of a large lead thread. A sleeve is sleeved on the screw rod. A slider is provided in the sleeve, and the slider is slidably connected with the spiral track.

[0007] The principle and beneficial effects of the utility model are as follows: when the hook body hooks the tying wire, the sleeve is pulled to make a linear motion. Since the spiral track is in the shape of a large lead thread, it is beneficial for the slider to move in the spiral track. The slider moves in the spiral track, forcing the screw rod to rotate, converting the linear motion into a rotational motion, and making the tying wire rotate and tie tightly. A large amount of working hours for manual rotation during tying are saved.

[0008] Solution 2, which is the preferred solution of the basic solution. A ratchet mechanism is provided inside the sleeve. The ratchet mechanism includes a ratchet and a detent pawl. The ratchet is fixedly connected to the slider, the slider is slidably connected to the spiral track, the detent pawl is fixedly connected to the sleeve, and the free rotation direction of the ratchet is opposite to the thread direction of the spiral track. When the sleeve is pulled, the ratchet will rotate relative to the screw. At this time, the detent pawl restricts the rotation of the ratchet, and the ratchet is relatively stationary with the sleeve. When the sleeve is reset, the ratchet rotates relative to the sleeve, and the sleeve is relatively stationary with the screw. When resetting, the sleeve will not drive the screw to rotate. The sleeve can be repeatedly pushed and pulled to make the binding wire more firmly tied, without removing the hook body and operating repeatedly.

[0009] Solution 3, which is the preferred solution of the basic solution. A limiter is threadedly connected to the screw, and the limiter is provided at both ends of the sleeve. By adjusting the position of the limiter, the length of the hook body protruding and the movement range of the sleeve can be adjusted. Operators can adjust the length of the tying hook according to their own usage habits to relieve work fatigue.

[0010] Solution 4, which is the preferred solution of the basic solution. A counterweight is rotatably connected to one end of the screw. During the tying wire operation, the counterweight can be used as a handle to maintain work stability. When a single tying wire operation is completed, the hook body is removed, and the counterweight can make the screw quickly reset under the action of gravity.

[0011] Solution 5, which is the preferred solution of the basic solution. An anti-slip rubber sleeve is provided on the outer side of the sleeve. This makes it firmer for the operator to hold.

[0012] Solution 6, which is the preferred solution of the basic solution. A lubricant is applied between the sleeve and the screw. The screw rotates more smoothly, is not prone to jamming, and reduces the labor intensity. Description of the Drawings

[0017] Embodiment

[0018] As Figure 1 and Figure 2As shown: A tying hook for quickly tying steel bars, comprising a hook body 1 and a screw rod 2. The hook body 1 is threadedly connected to the screw rod 2. A spiral track 3 is provided on the screw rod 2. The spiral track 3 is in the shape of a large lead thread. A sleeve 4 is sleeved on the screw rod 2. A ratchet mechanism 8 is provided inside the sleeve 4. The ratchet mechanism 8 includes a ratchet 9 and a detent pawl 10. The ratchet 9 is fixedly connected to a slider 7. The slider 7 is slidably connected to the spiral track 3. The detent 10 is fixedly connected to the sleeve 4. The free rotation direction of the ratchet 9 is opposite to the thread direction of the spiral track 3. A stopper 6 is threadedly connected to the screw rod 2. The stopper 6 is provided at both ends of the sleeve 4. One end of the screw rod 2 is rotatably connected to a counterweight 5. An anti-slip rubber sleeve 11 is provided on the outer side of the sleeve 4. A lubricant is applied between the sleeve 4 and the screw rod.

[0019] The implementation mode of this embodiment is as follows: Before tying the steel bars, adjust the position of the stopper 6 to limit the length of the hook body 1 extending out and the displacement range of the sleeve 4 to adapt to the working habits of the operators. Apply a lubricant between the sleeve 4 and the screw rod 2 and pull it back and forth several times to apply it evenly. When tying the steel bars, hook the hook body 1 on the tying wire, hold the anti-slip rubber sleeve 11 and pull the sleeve 4 to move in a straight line. At this time, the slider 7 moves in the spiral track 2, the ratchet 9 rotates relative to the screw rod 2, and the detent pawl 10 restricts the relative rotation between the ratchet 9 and the sleeve 4, forcing the screw rod 2 to rotate, and the hook body 1 drives the tying wire to rotate and tie tightly. If it is not tied tightly in one pass, push the sleeve 4 to reset. At this time, the ratchet 9 rotates relative to the screw rod 2, the sleeve 4 rotates relative to the ratchet 9, and the sleeve 4 is relatively stationary with respect to the screw rod 2. The screw rod 2 does not rotate during the reset process and will not untie the tying wire. Just push and pull the sleeve 4 back and forth like this to tie it firmly. After completing the tying work, remove the hook body 1, hold the hook body 1 upward and the screw rod 2 vertically. Under the action of the gravity of the counterweight 5, the sleeve 4 can be quickly reset.
