In the civil engineering construction process, the construction of reinforced concrete structure needs to carry out a large amount of reinforcement work, and reinforcement work is simple in flow but is the most time-consuming work among the reinforcement construction process. When binding the steel bar, the worker needs to rotate in coordination through the wrist to firmly bind the binding wire, the wrist is easy to be damaged due to long-time repeated operation, the time consumption of the worker when carrying out the steel bar binding by using the traditional binding hook is long, and the quality of the steel bar binding is difficult to ensure. The electric binding device improves the binding speed of the reinforcing steel bars, but has the defects of higher cost, long charging time and inapplicability to long-time and long-distance binding. Even if part of the mechanical binder does not need power, the device is easy to fall off due to design defects, so that the device is inconvenient to use and has part of potential safety hazards. Accordingly, it is desirable to design an anti-drop reinforcement binder 100 to solve the problems faced by current devices.

In some embodiments of the present application, as shown in connection with fig. 1-5, the anti-drop bar binder 100 includes a housing 110, a drive link 120, and an anti-drop link 130.

The transmission rod 120 is rotatably arranged in the shell 110, the head of the transmission rod is provided with a hook 121, and the hook 121 is used for binding wires; the outer surface of the transmission rod is provided with a spiral groove 122, and the spiral groove 122 is arranged corresponding to the spiral protrusion 111, so that the transmission rod 120 can be rotated up or rotated down in the housing 110. The middle part of the transmission rod 120 is provided with a containing part 123, and the middle part of the bottom of the transmission rod 120, namely the lower part of the containing part 123, is provided with a clamping part 124. The stop lever 131 at the upper part of the anti-drop rod 130 is inserted into the accommodating part 123, the upper side surface of the bottom disc 132 of the transmission rod 120 is connected with the lower bottom surface of the housing 110, and the top of the stop lever 131 is provided with a stop part 133.

Specifically, the outer case 110 is provided with textures to increase a contact area to increase friction force, preventing the ligator from falling down when in use. The outer diameter of the transmission rod 120 should be slightly smaller than the inner diameter of the housing 110, so that the transmission rod 120 can rotate in the housing 110, and the vertical center line of the transmission rod 120 can be kept consistent with the vertical center line of the housing 110 after the transmission rod 120 is unscrewed from the housing 110. Preventing the working efficiency from being affected by the difficulty in rotating the device caused by the inclination of the transmission rod 120.

In some embodiments of the present application, the shape of the housing 110 includes a circular tube shape and a square tube shape.

In order to ensure the quick unscrewing and retraction of the transmission rod 120, a certain space should be ensured between the accommodating portion 123 and the stop lever 131, and the contact surface does not need to be coated with a lubricant. And the bottom disc 132 of the anti-drop rod 130 is provided with a hollow structure to ensure that the inside of the shell 110 is communicated with the outside air, and the normal use is influenced by the negative pressure generated by placing. And a lubricant can be added at the hollowed-out position, so that the operation is convenient.

In some embodiments of the present application, the diameter of the receiving portion 123 is greater than the outer diameter of the limiting portion 133. The inner diameter of the clamping portion 124 is larger than the outer diameter of the limiting rod 131 and smaller than the outer diameter of the limiting portion 133.

Specifically, the outer diameter of the limiting portion 133 is larger than the inner diameter of the locking portion 124, so that the limiting portion 133 can be locked at the locking portion 124 to prevent the housing 110 from being separated from the force transmission system when the limit of the transmission rod 120 is reached under the action of external force.

The application process of the device specifically comprises the following steps:

1. bending back two complete long straight binding wires, and winding the steel bar crossing points to be bound;

4. after the binding of the steel bars is completed, the hooks 121 slide out from the bending openings of the binding wires, and the anti-falling steel bar binding device is vertically placed under the action of gravity to retract the transmission rod 120, so that the binding of the binding wires for one time is completed;

5. if the user finds that the use with a large friction is not sensitive, the transmission rod 120 can be rotated and slid out, and the lubricant can be injected into the transmission rod or the lubricant can be injected into the transmission rod through the bottom disc 132 to ensure that the transmission rod is lubricated, so that the friction resistance is reduced.

According to the anti-drop reinforcement bar binding device in the above embodiments, when the shell 110, the transmission rod 120 and the anti-drop rod 130 are arranged to bind reinforcement bars, rotation can be realized through the cooperation of the spiral protrusions 111 and the spiral grooves 122, the wrist does not need to be rotated, the operation is simple and convenient, the use is convenient, the working efficiency is improved, and the labor cost is reduced; the problem that drops easily when the transmission member 120 is tensile overlength has been solved in setting up of spacing portion 133 and joint portion 124, has promoted the safety in utilization of device, and the transmission member 120 is wrapped up comprehensively to the bottom disc 132 of shell 110 and anticreep member 130 bottom surface, further strengthens device safety in utilization, has avoided the potential safety hazard that probably causes when transmission member 120 rotates.
