[0001] This utility model relates to the technical field of rebar tying aids, and in particular to a rapid rebar tying aid for civil engineering. Background Technology

[0002] The rebar quick-tying aid is a tool used in the construction field to assist in completing rebar tying operations. Through a specific structural design, it enables rapid and efficient rebar tying, thereby improving construction efficiency and quality. It has the following structure:

[0003] 1. Operating end: Includes working heads such as hooks and flat heads, used for different pressing operations, and is the part that directly acts on the workpiece;

[0004] 2. Power transmission components: connect the working head to the power source, transmit electric drive force, and ensure the operation of the working head;

[0005] 3. Handle: Provides a handheld operating position for easy gripping and force application, and also integrates control components such as switches for starting and adjusting the equipment;

[0006] 4. Power source: Provides electricity for equipment operation, or may be a power supply module with an external power cord to ensure the realization of electric functions.

[0007] In the field of building construction, steel reinforcement binding is a key step in constructing a stable building structure. Its quality directly affects the overall strength and safety of the building. The steel reinforcement quick binding auxiliary device significantly improves the efficiency of steel reinforcement binding through the coordinated operation of the operating end, power transmission components, grip handle and power source.

[0008] However, in actual construction, the auxiliary device relies on the hand to hold the handle. Prolonged operation can easily lead to hand fatigue, causing the auxiliary device to slip out of the hand and eventually become damaged and fall off. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a quick-tying aid for civil engineering rebar, which solves the technical problem that in actual construction, the aid relies on the hand to hold the handle, which can easily lead to hand fatigue during long-term operation, causing the aid to slip out of the hand and thus become damaged and fall off.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A quick-tying aid for civil engineering rebar includes a handle, a hand rope on the outside of the handle, and an adjusting ring on the outside of the hand rope for adjusting the tightness of the hand rope. The adjusting ring has movable holes at both ends, and the two ends of the adjusting ring are slidably connected to the two ends of the hand rope through the movable holes. A fixing mechanism for fixing the position of the adjusting ring is provided outside the adjusting ring. The fixing mechanism includes a mounting groove, L-shaped blocks, springs, and through holes. The mounting groove is located outside the adjusting ring. There are two L-shaped blocks, both slidably connected inside the mounting groove. The two ends of the spring are fixedly connected to the adjacent sides of the two L-shaped blocks. There are two through holes, each located inside the mounting groove and communicating with the movable holes. The L-shaped blocks are slidably connected to the movable holes through the through holes.

[0012] Preferably, a crossbar is fixedly installed inside the mounting slot, and each L-shaped block has an opening on its outside. The L-shaped block is slidably connected to the outside of the crossbar through the opening. A deformation groove is provided on the outside of the crossbar, and two limiting spring pieces are fixedly connected inside the deformation groove.

[0013] Preferably, each movable hole has a pressure groove on one side of the corresponding through hole.

[0014] Preferably, the handle is fixedly connected to two mounting brackets at both ends of the corresponding hand rope, and the two ends of the hand rope are respectively tied to the outside of the two mounting brackets.

[0015] Preferably, the side of the adjusting ring away from the mounting groove is fixedly connected with a protective pad.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The operator puts the hand strap on their wrist, pulls the two L-shaped blocks to compress the springs, and moves the adjusting ring to bring the protective pad closer to the wrist. At this point, the L-shaped blocks are released, and they pass through the through hole into the moving hole to press the hand strap into the moving hole until the hand strap portion enters the pressing groove. At this point, the size of the hand strap is fixed. Therefore, even when the hand becomes weak due to prolonged high-intensity work, the auxiliary device can still be reliably connected to the wrist through the hand strap, preventing accidental slippage and damage, improving the safety of the auxiliary device and ensuring its service life.

[0018] Second, the limiting spring is deformed by the pressure of the inner wall of the opening. When the L-shaped block compresses the spring, the limiting spring can restrict the movement of the L-shaped block, thereby facilitating the movement of the adjusting ring and improving the convenience of operation.

[0027] This application provides a quick-tying aid for civil engineering rebar, which effectively solves the technical problem that in actual construction, the aid relies on the hand to hold the handle, and prolonged operation can easily lead to hand fatigue, causing the aid to slip out of the hand and thus be damaged and fall off. Example

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the technical solution in this application embodiment effectively solves the technical problem that in actual construction, the auxiliary device relies on the hand to hold the handle, and prolonged operation easily leads to hand fatigue, causing the auxiliary device to slip out of the hand and thus become damaged and fall off. The overall idea is as follows:

[0029] To address the problems existing in the prior art, this utility model provides a quick-tying aid for civil engineering rebar, including a handle 1, a hand rope 2 on the outside of the handle 1, and an adjusting ring 3 on the outside of the hand rope 2 for adjusting the tightness of the hand rope 2. The adjusting ring 3 has movable holes 4 at both ends, and the two ends of the adjusting ring 3 are slidably connected to the two ends of the hand rope 2 through the movable holes 4. A fixing mechanism for fixing the position of the adjusting ring 3 is provided on the outside of the adjusting ring 3. The fixing mechanism includes a mounting groove 5, two L-shaped blocks 6, a spring 7, and through holes 8. The mounting groove 5 is located on the outside of the adjusting ring 3. There are two L-shaped blocks 6, both of which are slidably connected inside the mounting groove 5. The two ends of the spring 7 are fixedly connected to the adjacent sides of the two L-shaped blocks 6. There are two through holes 8, each located inside the mounting groove 5 and communicating with the inside of the movable holes 4. The L-shaped blocks 6 are slidably connected to the inside of the movable holes 4 through the through holes 8.

[0030] A crossbar 9 is fixedly installed inside the mounting slot 5. Each L-shaped block 6 has an opening 10 on its outside. The L-shaped block is slidably connected to the outside of the crossbar 9 through the opening 10.

[0031] The crossbar 9 has a deformation groove 11 on its outside. Two limiting spring pieces 12 are fixedly connected inside the deformation groove 11. One end of the two limiting spring pieces 12 is fixedly connected inside the deformation groove 11, and the other end extends outward, pulling the two L-shaped blocks 6 to bring the two L-shaped blocks 6 closer to each other. During this process, the limiting spring pieces 12 are pressed by the inner wall of the opening 10.

[0032] Each movable hole 4 has a pressure groove 13 on one side of the inner surface of the corresponding through hole 8.

[0033] The handle 1 is fixedly connected to the two ends of the corresponding hand rope 2 with mounting brackets 14, and the two ends of the hand rope 2 are respectively tied to the outside of the two mounting brackets 14.

[0034] The side of the adjusting ring 3 away from the mounting groove 5 is fixedly connected to a protective pad 15.

[0035] Hand rope 2: Physically connects the wrist to the tool, preventing the operator from falling while using the binding aid, ensuring construction safety and tool life;

[0036] Adjusting ring 3: It is the core carrier for adjusting the tightness of the hand rope 2 by connecting it through the moving hole 4. It works with the fixing mechanism to lock the adjusted position and adapt to the wrist size of different operators.

[0037] Fixing mechanism: The mounting groove 5 provides built-in space for the L-shaped block 6 and the spring 7. The L-shaped block 6 is inserted into the moving hole 4 of the hand rope 2 through the through hole 8. The hand rope 2 is fixed by physical compression. The spring 7 provides the reset elasticity. After releasing, the L-shaped block 6 is automatically driven to reset and lock, which simplifies the operation steps and ensures the continuous squeezing force when locking. The through hole 8 forms the movement channel of the L-shaped block 6.

[0038] Crossbar 9 and opening 10: provide sliding guide for L-block 6, restricting its movement to a set direction and preventing L-block 6 from shifting due to compression by spring 7;

[0039] Deformation groove 11 and limiting spring 12: Provide elastic deformation space for limiting spring 12. Limiting spring 12 is deformed by compression through the inner wall of opening 10. When L-shaped block 6 compresses spring 7, limiting spring 12 can restrict the movement of L-shaped block 6, which facilitates the movement of adjusting ring 3. When L-shaped block 6 is reset, limiting spring 12 and spring 7 together restrict the movement of L-shaped block 6.

[0040] Pressure groove 13: Prevents the hand rope 2 from slipping out of the moving hole 4 when subjected to external force, improves the anti-detachment ability of the fixing mechanism, and ensures the long-term stability of the anti-loss function;

[0041] Mounting bracket 14: Serves as a connection point between the hand rope 2 and the handle 1, and the fastening structure facilitates the replacement of the hand rope 2;

[0042] Protective pad 15: A flexible buffer layer that directly contacts the wrist, reducing the pressure of the adjustment ring 3 on the skin.

[0043] Working principle:

[0044] First, the operator puts the wrist strap 2 on their wrist and pulls the two L-shaped blocks 6 to bring them closer together. At this time, the spring 7 is compressed. Then, the adjusting ring 3 is moved to bring the protective pad 15 closer to the wrist. Then, the L-shaped blocks 6 are released. The L-shaped blocks 6 enter the moving hole 4 through the through hole 8 to press the part of the wrist strap 2 located in the moving hole 4 until the part of the wrist strap 2 located in the moving hole 4 enters the pressing groove 13. At this time, the size of the wrist strap 2 is fixed.

[0045] The second step is to disconnect the hand rope 2 from the mounting frame 14 when it is damaged, and then process a new hand rope 2 and tie it to the mounting frame 14.

[0046] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
