Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation technology, and in particular to a safety rope hook that can be quickly installed. Background Technology

[0002] Safety rope hooks are crucial safety equipment used in high-altitude operations, climbing, and rescue scenarios to connect safety belts, safety ropes, and fixed anchor points. Their core function is to prevent falls and ensure operational safety. Currently, in high-altitude operations, climbing, and industrial rescue, safety rope hooks are widely used to connect safety belts to fixed anchor points as a key component of fall protection systems.

[0003] However, while most existing hook products have locking functions, their locking mechanisms generally use a traditional threaded rotating sleeve design. This requires multiple rotations of the locking sleeve to completely close the opening and closing mechanism. This method has significant efficiency issues in practical applications: First, in emergency situations or work scenarios requiring frequent movement, the cumbersome rotation locking steps significantly extend installation time and affect work efficiency. Second, in harsh environments such as wearing heavy gloves or high-altitude strong winds, operators may have difficulty accurately controlling the rotation, leading to incomplete locking and creating safety hazards. More seriously, in high-altitude operations where psychological pressure is high, the complex locking procedure can easily cause operators to make operational errors due to tension, such as failing to reach the required number of rotations or insufficient locking force. This will directly reduce the reliability of the fall arrest system. Utility Model Content

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0026] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] Example 1:

[0028] Reference Figures 1-4 This is the first embodiment of the present invention, which provides a quick-installable safety rope hook. The quick-installable safety rope hook includes a snap-fit ​​component 4. After the buckle plate 2 completes its elastic reset under the action of the torsion spring at the hinge, the operator only needs to push the movable frame 3 to drive the toothed plate 402 to move up the inclined surface. During this process, the inclined surface of the toothed plate 402 and the inner wall of the tooth groove 5 form a continuous engagement. The progressive snap-fit ​​is achieved through the elastic deformation of the spring assembly 401. When the movable frame 3 completely covers the surface of the tooth groove 5, the reset force of the spring assembly 401 will precisely guide the toothed plate 402 back to its original position and form a stable snap-fit ​​with the tooth groove 5. This innovative design not only achieves true one-handed quick installation and significantly improves operating efficiency, but more importantly, it greatly enhances the overall strength of the hook opening through a multi-mechanical interlocking structure, effectively solving the safety hazards such as cumbersome operation and insufficient locking force of the traditional threaded locking method.

[0029] A buckle plate 2 is hinged to one side of the hook body 1 by a torsion spring. A movable frame 3 is provided on one side of the buckle plate 2. A snap fastener 4 is provided on one side of the movable frame 3. A toothed groove 5 is arrayed on one side of the hook body 1 to cooperate with the snap fastener 4.

[0030] The hook body 1 and the snap plate 2 hinged by the torsion spring can be easily snapped into the suspension support position. The movable frame 3, together with the snap fastener 4 and the toothed groove 5, can quickly install and position the snap plate 2 after it is snapped into place and the opening and closing part between the hook body 1. This solves the safety hazards such as cumbersome operation and insufficient locking force of the traditional threaded locking method.

[0031] The snap-fit ​​component 4 includes a spring assembly 401, which is fixed to one side of the movable frame 3. One end of the spring assembly 401 is fixedly connected to a toothed plate 402, and one side of the toothed plate 402 is fixedly connected to a pull rod 403 that is slidably connected to the inside of the movable frame 3.

[0032] After the buckle plate 2 completes its elastic reset under the action of the torsion spring at the hinge, the operator only needs to push the movable frame 3 to drive the toothed plate 402 to move up the inclined surface. During this process, the inclined surface of the toothed plate 402 and the inner wall of the tooth groove 5 form a continuous engagement. The progressive engagement is achieved through the elastic deformation of the spring assembly 401. When the movable frame 3 completely covers the surface of the tooth groove 5, the reset force of the spring assembly 401 will accurately guide the toothed plate 402 back to its original position and form a stable engagement with the tooth groove 5. The pull rod 403 facilitates the subsequent direct pulling of the toothed plate 402 away from the inside of the tooth groove 5. Alternatively, the toothed plate 402 can be disengaged from the inside of the tooth groove 5 by pressing.

[0033] Example 2:

[0034] Reference Figures 1-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0035] Specifically, a sloping plate 404 is provided on one side of the movable frame 3, and a limiting groove 405 is provided inside the pull rod 403 to cooperate with the sloping plate 404. A push block 411 is fixedly connected to the bottom of the sloping plate 404.

[0036] The inclined plate 404 is slidably connected to the inside of the limiting groove 405, and the push block 411 is semi-circular, which makes it easy to fit the fingers of the staff. The distance after the inclined plate 404 is fully inserted into the limiting groove 405 is enough for the pull rod 403 to drive the toothed plate 402 to disengage from the inside of the toothed groove 5. Therefore, when the user needs to remove the limiting between the buckle plate 2 and the hook body 1, he can directly push the push block 411 to drive the inclined plate 404 to press against the limiting groove 405. Then the pull rod 403 will drive the toothed plate 402 to move to one side and compress the spring assembly 401 to disengage from the inside of the toothed groove 5.

[0037] Specifically, a retaining groove 406 is provided on one side of the movable frame 3, and sliders 407 that are slidably connected to the inside of the retaining groove 406 are fixedly connected to both sides of the push block 411.

[0038] Through the sliding connection between the retaining groove 406 and the slider 407, when the push block 411 moves, it will drive the slider 407 to move within the retaining groove 406, thereby limiting the slider 407 to move on one side of the movable frame 3.

[0039] Specifically, sliding plates 408 are fixedly connected to both the front and rear sides of the toothed plate 402, and connecting grooves 409 are opened on both the front and rear sides of the buckle plate 2 and the hook body 1.

[0040] The sliding plate 408 is fixed to both sides of the toothed plate 402, which facilitates the limiting of the movement position of the toothed plate 402. The connecting groove 409 facilitates the stable insertion of the subsequent movable frame 3.

[0041] Specifically, both the front and rear sides of one side of the movable frame 3 are fixedly connected with retaining blocks 410 that are slidably connected to the inside of the connecting groove 409, and the surface of the sliding plate 408 is slidably connected to the inside of the retaining blocks 410.

[0042] By setting the retaining block 410, the sliding plate 408 can be strengthened and limited. On the other hand, the retaining block 410 can slide parallel from the connecting groove 409 on the buckle plate 2 to the inside of the connecting groove 409 on the hook body 1, thereby not only improving the strength of the toothed plate 402, but also improving the installation strength of the movable frame 3.

[0043] Specifically, the front and rear sides of the buckle plate 2 are provided with sliding grooves 6, and the front and rear sides of the movable frame 3 are fixedly connected with sliding plates 7 that are slidably connected to the inside of the sliding grooves 6.

[0044] The sliding connection between the slide groove 6 and the slide plate 7 can improve the strength of the movable frame 3 when it moves up and down on both sides, and at the same time ensure that the movable frame 3 will not shake when it moves up and down.

[0045] Example 3:

[0046] Reference Figures 1-4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0047] Specifically, a reinforcing block 8 is fixedly connected to one side of the skateboard 7, and one side of the reinforcing block 8 is fixedly connected to the movable frame 3.

[0048] By fixing the reinforcing block 8 between the slide plate 7 and the movable frame 3, the connection strength between the two can be improved, thereby ensuring its stability and durability after long-term use.

[0049] Specifically, a positive magnet 9 is fixedly connected to one side of the buckle plate 2, and a negative magnet 10, which works in conjunction with the positive magnet 9, is fixedly connected to one side inside the hook body 1.

[0050] Since both the positive magnet 9 and the negative magnet 10 are strong magnets, when the buckle 2 is reset and attached to the hook body 1, the two magnets will attract each other with high strength, achieving a fast and stable effect.

[0051] Specifically, a support column 11 is rotatably connected to the bottom of the inner cavity of the hook body 1, a limit ring 12 is fixedly connected to the top of the support column 11, and a hanging ring 13 is sleeved inside the support column 11.

[0052] By rotating the support column 11 inside the hook body 1, and when the rope is attached to the hanging ring 13, it can prevent the rope from rotating and causing entanglement. The limiting ring 12 can limit the position of the support column 11 as it descends, ensuring the strength of the support column 11.

[0053] Specifically, a reinforcing plate 14 is fixedly connected to the surface of the support column 11, and a limiting frame 15, which is fixedly connected to the hook body 1, is movably connected to the surface of the support column 11.

[0054] The reinforcing plate 14 and the limiting frame 15 can achieve the effect of double-layer reinforcement of the support column 11, preventing the hanging ring 13 from being pulled by the rope too much, which would cause the support column 11 to detach from the hook body 1.

[0055] In use, first, the worker's own rope is secured with the hanging ring 13. Then, the buckle plate 2 on the hook body 1 is pressed down and hung at the fixed point. Then, the buckle plate 2 is loosened. After the buckle plate 2 completes its elastic reset under the action of the torsion spring at the hinge, the positive magnetic attraction 9 and the negative magnetic attraction 10 are both strong magnets. Therefore, when the buckle plate 2 is reset and attached to the hook body 1, the two magnetic attraction will attract each other with high strength, achieving a quick and stable effect. Then, the user pushes the movable frame 3, causing the slide plate 7 to move up and down within the limited position of the slide groove 6. Then, the movable frame 3 is moved upward a bit. At this time, the pull rod 403 inside the movable frame 3 and the sliding plate 408 slidably connected inside the retaining block 410 will restrain the toothed plate 402 from moving upward. During this process, the inclined surface of the toothed plate 402 and the inner wall of the tooth groove 5 form a continuous engagement. The progressive locking is achieved through the elastic deformation of the spring group 401. As the retaining block 410 gradually slides into the connection inside the hook body 1, the user moves the toothed plate 402 upward. Inside the groove 409, when the movable frame 3 completely covers the surface of the toothed groove 5, the restoring force of the spring assembly 401 will precisely guide the toothed plate 402 back to its original position and form a stable engagement with the toothed groove 5, thereby achieving a fast and high-strength installation effect. If the user needs to release the limiting position of the toothed plate 402 and allow the movable frame 3 to descend and detach from the covering hook body 1, the push block 411 will be pushed up and the inclined plate 404 will press against the limiting groove 405. Subsequently, the pull rod 403 will drive the toothed plate 402 to move to one side and compress the spring assembly 401 to detach from the inside of the toothed groove 5. When the push block 411 moves, it will drive the slider 407 to move within the fixed groove 406. This innovative design not only achieves true one-handed fast installation and significantly improves operating efficiency, but more importantly, it greatly enhances the overall strength of the hook opening through multiple mechanical interlocking structures, effectively solving the safety hazards such as cumbersome operation and insufficient locking force of traditional threaded locking methods.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
