Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of safety rope buckle components, and in particular to a high-altitude safety rope buckle for building construction. Background Technology
[0002] The primary function of safety ropes used in construction is to securely fasten workers to their positions at heights, preventing accidental falls and protecting their lives. Safety rope fasteners are key components connecting the safety belt and the safety rope, and their design aims to ensure the safety of workers at heights.
[0003] Safety rope fasteners for high-altitude work are typically made of high-strength, lightweight, and wear-resistant materials, such as stainless steel or alloy steel, to withstand enormous tensile forces and ensure long-term use. They tightly connect the safety belt to the safety rope, ensuring that even if a person accidentally sways or loses balance while working at height, the fasteners and safety rope will effectively prevent falls.
[0004] In existing technologies, safety rope fasteners typically employ a snap-fit structure and can be infinitely reset, allowing for multiple uses. However, in dangerous high-altitude work, using a single locking mechanism to connect two ropes can lead to high-altitude accidents due to locking failure when wear is severe. Therefore, a high-altitude safety rope fastener for construction is proposed to address these issues. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a high-altitude safety rope fastener for construction, which aims to improve the problem that although the existing safety rope fastener can be used multiple times, it is prone to failure due to wear when locking the two ropes only once in dangerous high-altitude operations.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A high-altitude safety rope fastener for construction includes a fastening ring. The fastening ring is externally fixedly connected to a connecting component for directly connecting a rope to one side. A spiral tube is threadedly connected to the external side of the connecting component. A threaded post is externally fixedly connected to the fastening ring. The inner wall of the spiral tube is threadedly connected to the outside of the threaded post. A movable bar is rotatably connected to the external side of the fastening ring. A groove is formed on the inner wall of the fastening ring. The movable bar is slidably connected to the inner wall of the groove. A limiting component is externally fixedly connected to the fastening ring to restrict the movement position of the movable bar. An auxiliary component is fixedly connected to the inner wall of the fastening ring to reset the movable bar.
[0008] As a further description of the above technical solution:
[0009] The connecting assembly includes a positioning ring, which is externally fixedly connected to the outside of the fastening ring, and a threaded tube is externally fixedly connected to the outside of the positioning ring.
[0010] As a further description of the above technical solution:
[0011] The limiting component includes a limiting block, the bottom of which is fixedly connected to the outside of the fastening ring, and a sliding plate is fixedly connected to the outside of the moving strip.
[0012] As a further description of the above technical solution:
[0013] The auxiliary component includes a spring, and the inner wall of the fastening ring has a slide rail, with one end of the spring fixedly connected to the inner wall of the slide rail.
[0014] As a further description of the above technical solution:
[0015] The inner wall of the spiral tube is threaded to the outside of the spiral tube, and multiple friction blocks are fixedly connected to the outside of the spiral tube.
[0016] As a further description of the above technical solution:
[0017] The sliding plate is slidably connected to the outside of the fastening ring, and the outside of the sliding plate is in contact with the inner wall of the limiting block.
[0018] As a further description of the above technical solution:
[0019] The other end of the spring is fixedly connected to a sliding block, and the outer side of the sliding block is slidably connected to the inner wall of the slide.
[0020] As a further description of the above technical solution:
[0021] The other end of the sliding block is fixedly connected to the outside of the moving bar, and a soft pad is fixedly connected to the outside of the moving bar.
[0022] This utility model has the following beneficial effects:
[0023] 1. In this utility model, the movement of the moving bar causes the sliding block to move, which in turn causes the spring to deform. The spring's reset can cause the sliding block to reset, thereby causing the sliding block to pull the moving bar to reset, thus eliminating the passage. The spiral tube is rotated in the opposite direction, causing the inner wall of the spiral tube to contact and lock with the outer side of the threaded column, thus eliminating the passage. The rope loop is then doubly locked. The safety rope fastener with a double locking structure can greatly improve the safety of high-altitude operations and add an extra layer of safety mechanism.
[0024] 2. In this utility model, multiple friction blocks increase the friction of the fingers gripping, thereby making it easier to rotate and achieve the desired effect faster; the outside of the moving strip is provided with a soft pad, which is installed on the side of the moving strip that is frequently touched. Because the outer side of the moving strip is thin and hard, long-term direct contact can easily cause damage to the inside of the thumb. Attached Figure Description

[0031] 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.
[0032] Reference Figure 1 and Figure 3This utility model provides an embodiment of a high-altitude safety rope fastener for construction, comprising a fastening ring 1. The fastening ring 1 is externally fixedly connected to a connecting component for directly connecting one side of the rope. The connecting component includes a positioning ring 2, which is externally fixedly connected to the outside of the fastening ring 1. The positioning ring 2 directly fixes one side of the rope without requiring adjustment and is a stable part within the safety rope. A threaded tube 11 is externally fixedly connected to the positioning ring 2, and the positioning ring 2 fixes the position of the threaded tube 11. The inner wall of a spiral tube 13 is threadedly connected to the outside of the threaded tube 11, allowing the spiral tube 13 to approach the threaded tube 11 during rotation and preventing it from detaching from the structure. Multiple friction blocks 14 (as shown in the attached diagram) are externally fixedly connected to the spiral tube 13. Figure 3 This increases the friction of the spiral tube 13, making it easier to use.
[0033] The connecting assembly has an external threaded connection to a helical tube 13, and a threaded post 12 is fixedly connected to the outside of the fastening ring 1. The inner wall of the helical tube 13 is threaded to the outside of the threaded post 12, and the helical tube 13 can be rotated to move closer to or further away from the threaded post 12. A movable strip 5 is rotatably connected to the outside of the fastening ring 1, and the movable strip 5 can be rotated to move away from the side of the fastening ring 1. A groove 6 is formed on the inner wall of the fastening ring 1, and the outer side of the movable strip 5 is slidably connected to the inner wall of the groove 6, allowing the movable strip 5 to return to its original position along the groove 6, and also protecting one end of the movable strip 5.
[0034] Reference Figure 1 The fastening ring 1 is externally fixedly connected to a limiting component that restricts the movement position of the moving bar 5. The limiting component includes a limiting block 3, the bottom of which is fixedly connected to the outside of the fastening ring 1. The fastening ring 1 has a fixed position function for the limiting block 3. The moving bar 5 is externally fixedly connected to a sliding plate 4. The movement of the moving bar 5 causes the sliding plate 4 to move. The sliding plate 4 is externally slidably connected to the outside of the fastening ring 1, and the outside of the sliding plate 4 contacts the inner wall of the limiting block 3. The limiting block 3 has a position-limiting function for the movement trajectory of the sliding plate 4, ensuring that the sliding plate 4 can only move along its inner side.
[0035] Reference Figure 2 and Figure 4 The inner wall of the fastening ring 1 is fixedly connected to an auxiliary component for resetting the moving bar 5. The auxiliary component includes a spring 9. A slide rail 8 is provided on the inner wall of the fastening ring 1. One end of the spring 9 is fixedly connected to the inner wall of the slide rail 8, and the inner wall of the slide rail 8 provides a fixed position for one end of the spring 9. The other end of the spring 9 is fixedly connected to a sliding block 10 (as shown in the attached figure). Figure 4The movement of the sliding block 10 causes the spring 9 to deform, and the return of the spring 9 causes the sliding block 10 to return to its original position. The outer side of the sliding block 10 is slidably connected to the inner wall of the slide rail 8, allowing the sliding block 10 to move along a specific trajectory. The other end of the sliding block 10 is fixedly connected to the outside of the moving bar 5, and the movement of the moving bar 5 causes the sliding block 10 to move. A soft pad 7 is fixedly connected to the outside of the moving bar 5, which is used to protect the fingers that come into direct contact with it.
[0036] Working principle: Rotating the spiral tube 13 causes it to disengage from the threaded post 12, creating a channel between the spiral tube 13 and the threaded post 12 that allows the rope to be locked to pass through. At this point, pressing the soft pad 7 causes the moving strip 5 to move, allowing one end of the moving strip 5 to slide along the inner wall of the groove 6, eventually disengaging from the groove 6. This creates a passage between the fastening ring 1 and the moving strip 5. The rope to be locked is then inserted between the channel and the passage. The movement of the moving strip 5 then causes the sliding block 10 to move, deforming the spring 9. The return of the spring 9 can then... The sliding block 10 is reset, which in turn causes the sliding block 10 to pull the moving bar 5 to reset, thus eliminating the passage. The spiral tube 13 is rotated in the opposite direction, causing the inner wall of the spiral tube 13 to contact and lock with the outer side of the threaded column 12, thus eliminating the passage. The rope loop is then double-locked. The double-locking structure of the safety rope fastener can greatly improve the safety of high-altitude operations, adding an extra layer of safety mechanism. It effectively avoids the risk of locking failure due to wear or malfunction of a single locking component, ensuring that even if one locking point has a problem, the other can still be firmly connected, preventing the rope from falling off, providing more reliable safety protection for workers, and reducing the occurrence of high-altitude accidents.
[0037] The spiral tube 13 has multiple friction blocks 14 on its outside to increase the friction when gripped by the fingers, making it easier to rotate and achieve the desired effect faster. The movable strip 5 has a soft pad 7 on its outside, installed on the side that the movable strip 5 is frequently touched. Since the outer side of the movable strip 5 is thin and hard, long-term direct contact can easily cause damage to the inside of the thumb. The rotation of the movable strip 5 drives the sliding plate 4 to rotate. The rotation of the sliding plate 4 is along the inner side of the limiting block 3, which limits the rotation position of the movable strip 5, so that the rotation of the movable strip 5 can follow a specific trajectory, so that subsequent multiple resets can be performed smoothly.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
