Description

Technical Field

[0001] This utility model relates to the field of locking technology, specifically a safety rope locking buckle. Background Technology

[0002] In fields such as high-altitude operations, rock climbing, and fire rescue, safety ropes are core equipment for ensuring the safety of personnel, and the reliability of their locking buckles is directly related to the safety of the workers.

[0003] Most locks typically employ a mechanical locking structure where a rod engages with a positioning slot, and a spring provides the rod's restoring force to ensure a secure engagement when the lock is closed. However, over time, the spring is prone to failure due to fatigue, corrosion, or other reasons, causing the rod to fail to fully insert into the positioning slot, resulting in a "false lock." During operation, this can easily lead to the rod disengaging due to its inability to withstand the actual load. Although users may check the lock after insertion, this is extremely inconvenient, especially at night, increasing the risk of misjudgment. To address these issues, the inventor proposes a safety rope lock to solve the problems mentioned above. Utility Model Content

[0004] To address the problem that checking the locking mechanism is extremely inconvenient when the user is operating the device at night, the purpose of this invention is to provide a safety rope lock.

[0005] To solve the above technical problems, the present invention adopts the following technical solution: a safety rope buckle, including a buckle main rod, one end of which is fixedly connected to a limiting rod, and the other end of which is fixedly connected to a straight tube, with the limiting rod located above the straight tube. A positioning groove is provided at the center of the bottom end of the limiting rod, and a second limiting hole is provided on the outer ring of the limiting rod near the bottom. A first insert shaft is slidably inserted at the center of the top end of the straight tube, and a first spring is fixedly connected to the bottom end of the first insert shaft, with the other end of the first spring fixedly connected to the inner wall of the straight tube. A first insert rod is fixedly connected to the top end of the first insert shaft, and the insert rod is adapted to the positioning groove. A display groove is provided on the outer ring of the straight tube near the top, and two mounting grooves are provided on the outer ring of the first insert shaft near the bottom, with the mounting grooves and the display grooves being at the same level. A red reflective strip is provided inside one of the mounting grooves, and a green reflective strip is provided inside the other mounting groove.

[0006] Preferably, a limiting hole one is provided inside the insertion rod near the top, and the limiting hole one is adapted to the limiting hole two.

[0007] Preferably, an L-shaped tube is fixedly connected to the outer ring of the limiting rod near the bottom, and an installation box is fixedly connected to the outer ring of the L-shaped tube at the same level as the limiting hole two. A second insertion shaft is slidably inserted into the side end of the installation box near the limiting hole two, and the second insertion shaft is adapted to the limiting hole two.

[0008] Preferably, a second spring is fixedly connected to the other end of the second insertion shaft, and the other end of the second spring is fixedly connected to the inner wall of the mounting box. An auxiliary plate is fixedly connected to the outer ring of the second insertion shaft near the center.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. In this utility model, when the spring is working properly and the plug is fully inserted into the positioning groove, the green reflective strip moves to the display groove. If the plug is not fully inserted due to a malfunction of the spring, the red reflective strip will be at the same level as the display groove, which can promptly alert the user in the case of insufficient light and effectively avoid safety problems that may be caused by the plug not being fully inserted.

[0011] 2. In this utility model, after the insertion rod is inserted into the positioning groove, the auxiliary plate is released, and the spring two drives the insertion shaft two to move towards the limiting rod. The insertion shaft two is inserted into the limiting hole two and the limiting hole one, thereby achieving the effect of locking the position of the insertion rod. This can effectively prevent the insertion rod from coming off the hook and further ensure the safety of use. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Figure 1-4 As shown, this utility model provides a technical solution: a safety rope lock, including a lock main rod 1, a limiting rod 11 fixedly connected to one end of the lock main rod 1, and a straight tube 12 fixedly connected to the other end of the lock main rod 1, with the limiting rod 11 located above the straight tube 12. A positioning groove 3 is provided at the center of the bottom end of the limiting rod 11, and a second limiting hole 31 is provided on the outer ring of the limiting rod 11 near the bottom. A first insertion shaft 2 is slidably inserted at the center of the top end of the straight tube 12, and a first spring 21 is fixedly connected to the bottom end of the first insertion shaft 2, with the other end of the first spring 21 fixedly connected to the inner wall of the straight tube 12. A second insertion rod 22 is fixedly connected to the top end of the first insertion shaft 2, and the second insertion rod 22 is adapted to the positioning groove 3. A second positioning hole 31 is provided on the outer ring of the straight tube 12 near the top. The display slot 26 has two mounting slots 24 on its outer ring near the bottom of the insertion shaft 2. The mounting slots 24 are at the same level as the display slot 26. One mounting slot 24 has a red reflective strip 25 inside, which can be used to install reflective strips or reflective blocks to make it easy for the user to notice. The other mounting slot 24 has a green reflective strip 27 inside, which is located below the red reflective strip 25. When the limiting hole 23 is inserted into the positioning slot 3, the display slot 26 will display the green reflective strip 27, which proves that the insertion rod 22 is reset and inserted into the positioning slot 3. If it is not inserted into place, the red reflective strip 25 is at the same level as the display slot 26. The limiting hole 31 and the positioning slot 3 are arranged in a cross pattern.

[0020] A limiting hole 23 is provided inside the insertion rod 22 near the top, and the limiting hole 23 is adapted to the limiting hole 31.

[0021] By adopting the above technical solution, a limiting hole 23 is set inside the insertion rod 22 in order to accommodate the insertion shaft 41 so that it can be inserted into the limiting hole 23 and complete the limiting work of the insertion rod 22.

[0022] An L-shaped tube 13 is fixedly connected to the outer ring of the limiting rod 11 near the bottom. An installation box 4 is fixedly connected to the outer ring of the L-shaped tube 13 at the same level as the limiting hole 31.

[0023] By adopting the above technical solution, an L-shaped tube 13 is set near the bottom of the outer ring of the limiting rod 11 in order to install and fix the mounting box 4. The size of the L-shaped tube 13 is set according to the actual use requirements so that it will not affect the normal operation of the lock.

[0024] The mounting box 4 has a sliding insertion shaft 41 on one side near the limiting hole 31, and the insertion shaft 41 is adapted to the limiting hole 31.

[0025] By adopting the above technical solution, an elongated hole is provided inside the mounting box 4 to facilitate the horizontal movement of the insertion shaft 41.

[0026] A spring 42 is fixedly connected to the other end of the insertion shaft 41, and the other end of the spring 42 is fixedly connected to the inner wall of the mounting box 4.

[0027] By adopting the above technical solution, a spring 42 is provided on the side end of the second insertion shaft 41 in order to achieve the effect of resetting the second insertion shaft 41.

[0028] An auxiliary plate 43 is fixedly connected to the outer ring of the second insert shaft 41 near the center.

[0029] By adopting the above technical solution, an auxiliary plate 43 is provided on the outer ring of the second insert shaft 41 to facilitate the movement of the second insert shaft 41.

[0030] Working principle: When using this device, first move the auxiliary plate 43 towards the L-shaped tube 13, then press down on the insertion shaft 2 to compress the spring 21 and wrap its safety rope inside the locking rod 1. Then release the force on the insertion shaft 2, which will allow the spring 21 to return to its original position and drive the insertion shaft 2 to be inserted into the positioning groove 3. This will also allow the green reflective strip 27 to move to the display groove 26. If the insertion rod 22 is not fully inserted into the positioning groove 3 due to a malfunction of the spring 21, the red reflective strip 25 will be at the same level as the display groove 26, thus facilitating timely reminders to the user in low light conditions.

[0031] After the insertion rod 22 is inserted into the positioning groove 3, the force on the auxiliary plate 43 can be released, so that the spring 2 42 drives the insertion shaft 2 41 to move towards the limiting rod 11. Once the insertion shaft 2 41 is inserted into the limiting hole 2 31 and the limiting hole 1 23, the position of the insertion rod 22 is locked, thereby preventing the insertion rod 22 from disengaging.

[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
