Description

Technical Field

[0001] This utility model relates to the field of high-altitude work safety equipment technology, and in particular to a portable anti-detachment safety belt fastening point device. Background Technology

[0002] Safety harness anchoring points for high-altitude operations are a crucial element in ensuring the safety of workers and have received significant attention from the industry both domestically and internationally in recent years. Traditional safety harness anchoring systems suffer from multiple limitations in high-altitude operations, including improper anchor point selection, complex anchoring operations, dynamic environmental risks, poor equipment compatibility, and maintenance and aging hazards, leading to frequent falls from heights. Statistics show that approximately 75% of high-altitude accidents in the construction industry are directly related to improper anchoring point placement or safety harness detachment, resulting in serious personal injury and economic losses. Against this backdrop, portable anti-detachment safety harness anchoring devices have emerged, and their technical features and current development are gradually changing the landscape of safety protection for high-altitude operations.

[0003] Chinese patent CN118217557A discloses a portable safety belt fastening point device, including a safety belt fastening point body. One end of the safety belt fastening point body is an integrally bent triangular structure for fastening the safety belt. The safety belt fastening point body is equipped with an anti-rotation limiting device. The other end of the safety belt fastening point body has a first slot in the middle. An installation pin is provided inside the first slot near the side of the triangular structure. A rotating locking pin is installed inside the first slot and is rotatably installed in the first slot through the installation pin. This application is simple to manufacture, convenient to use, safe and reliable, easy to carry, and has low production and manufacturing costs, which is conducive to promotion. The anti-rotation limiting device can prevent the safety belt fastening point body from rotating. The rotating locking pin automatically turns to a straight state due to its own weight, causing the safety belt fastening point to fall off. The anti-rotation limiting device is easy to use, improves the wearing rate and utilization rate of workers' safety belts, and reduces the safety risks of working at heights.

[0004] However, the above-mentioned portable seat belt fastening device still has the following problems when in use: (1) The portable seat belt fastening device is locked by the gravity of the rotating pin, which cannot be adapted to the top fastening point limit; (2) The rotating pin in the portable seat belt fastening device lacks an effective anti-rotation or limit locking mechanism, and the pin is prone to deflection or slippage under external impact or vibration. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a portable anti-slip safety belt attachment point device. On the one hand, the device is stable and reliable during use through multiple limiting and anti-slip designs (such as limiting blocks, slots, and limiting seats). On the other hand, the rotating seat allows the hanging ring to rotate freely within a certain range, reducing the impact of torque caused by personnel movement on the rope.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] This application provides a portable anti-slip safety belt fastening device, including a sleeve with a hanging ring connected to the bottom end of the sleeve; it also includes a support mechanism and a rotating mechanism; the support mechanism is movably disposed inside the sleeve for detachably connecting the sleeve to a pre-reserved hole; the rotating mechanism is movably connected between the support mechanism and the hanging ring for preventing the rope from getting tangled when the hanging ring rotates.

[0008] Furthermore, the support mechanism includes multiple support components movably connected to the circumferential direction of the sleeve sidewall; a limiting block for pushing the support component is provided below the support component; an adjusting rod is movably sleeved inside the sleeve; the top of the adjusting rod is rotatably connected to the bottom of the limiting block.

[0009] Furthermore, the support assembly includes a rotating shaft rotatably connected to the sleeve; a support rod is connected to the rotating shaft to prevent the sleeve from slipping above the reserved hole; and a limiting rod is also connected to the rotating shaft and is perpendicular to the support rod.

[0010] Furthermore, the rotating mechanism includes a rotating seat rotatably sleeved on the bottom of the adjusting rod; a limiting seat is provided above the rotating seat to prevent the rotating seat from slipping; and the hanging ring is connected to the bottom of the rotating seat.

[0011] Furthermore, the sleeve has multiple slots for engaging the corresponding support rods; the sleeve also has a threaded groove inside that engages with the threaded adjustment rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. Multiple limiting and anti-slip designs (such as limiting blocks, slots, and limiting seats) ensure the device's stability and reliability during use. No additional installation tools or complex construction are required. It is suitable for various sizes of pre-drilled holes and prevents rope entanglement or knotting caused by the rotation of the hanging ring, avoiding safety hazards. The overall structure is compact, with most components connected by movable joints, facilitating disassembly and transport to different work sites. The support mechanism can adapt to various hole diameters, making it widely applicable in various high-altitude work scenarios such as construction, power, and bridge construction.

[0014] 2. After the support rod extends, it abuts against the edge of the hole to prevent the entire device from falling accidentally. The support assembly uses a rotating connection method, which facilitates storage and deployment, improving portability. In use, the support rod is extended by moving the adjusting rod upward to drive the limiting block. After use, the support rod can be quickly retracted by external pulling force to adapt to different hole sizes.

[0015] 3. The rotating seat allows the hanging ring to rotate freely within a certain range, preventing the rope from twisting or tangling due to personnel movement. The free rotation of the hanging ring reduces the impact of torque generated by personnel movement on the rope. At the same time, the limit seat prevents the rotating seat from falling off, ensuring stability and safety during rotation, reducing rope wear, and improving the durability of the safety belt system.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0026] Combination Figure 1-5 As shown, this utility model provides a portable anti-slip safety belt fastening device, including a sleeve 1 with a hanging ring 2 connected to the bottom end of the sleeve 1; it also includes a support mechanism 3 and a rotating mechanism 4; the support mechanism 3 is movably disposed inside the sleeve 1 for detachably connecting the sleeve 1 to a reserved hole; the rotating mechanism 4 is movably connected between the support mechanism 3 and the hanging ring 2 for preventing the rope from getting tangled when the hanging ring 2 rotates.

[0027] Specifically, the sleeve 1 is a cylindrical structure and serves as the main load-bearing component of the entire device, transferring external loads to the support mechanism 3. The sleeve 1 is made of lightweight and high-strength metal. The hanging ring 2 is used to connect the safety rope to the safety harness. It can rotate freely via the rotating mechanism 4, preventing the rope from twisting due to personnel movement. It is also made of high-strength and wear-resistant metal. In use, the top of the sleeve 1 is passed through the pre-drilled hole, the support mechanism 3 is manually unfolded, and the safety rope is then attached to the hanging ring 2 for high-altitude work.

[0028] Furthermore, the support mechanism 3 includes multiple support components 31 movably connected to the circumferential side wall of the sleeve 1; a limiting block 32 for pushing the support component 31 is provided below the support component 31; an adjusting rod 33 is movably fitted inside the sleeve 1; the top of the adjusting rod 33 is rotatably connected to the bottom of the limiting block 32. The support component 31 includes a rotating shaft 311 rotatably connected to the sleeve 1; a support rod 312 for preventing the sleeve 1 from slipping above the reserved hole is connected to the rotating shaft 311; a limiting rod 313 perpendicularly arranged to the support rod 312 is also connected to the rotating shaft 311.

[0029] The adjusting rod 33 has an external thread and is threadedly connected to the sleeve 1. A handwheel 34 is fitted at the bottom to facilitate manual rotation of the adjusting rod 33. When the adjusting rod 33 rotates, it can move up and down through the threaded transmission, which drives the limit block 32 to rise and fall. When the adjusting rod 33 rotates, the limit block 32 does not rotate. The limiting block 32 is a combination of a frustum and a cylinder. Its inclined surface allows the support component 31 to gradually unfold outwards. The cylindrical structure at its bottom can stably support the support component 31 after it unfolds. The top of the sleeve 1 has a cavity that mates with the limiting block 32. When the limiting block 32 rises to its limit, the limiting rod 313 rotates 90 degrees and fits against the inner wall of the sleeve 1. At this time, the support rod 312 rotates to the outside of the sleeve 1 and is perpendicular to the axis of the sleeve 1, resting on the outer periphery of the reserved hole, playing a role in stable support. The outer wall of the frustum structure of the limiting block 32 blocks the limiting rod 313, preventing the support rod 312 and the limiting rod 313 from rotating under the force of the entire device, thereby preventing the sleeve 1 from slipping out of the reserved hole.

[0030] The rotating shaft 311 is rotatably connected to the side wall of the sleeve 1 via a connecting rod. The support rod 312 is vertically mounted on the side wall of the rotating shaft 311, and the limiting rod 313 is also mounted on the side wall of the rotating shaft 311. The bottom end of the limiting rod 313 contacts the top end of the limiting block 32 and engages with the inclined surface of the limiting block 32. When the limiting block 32 moves upward, it pushes the limiting rod 313 to rotate the rotating shaft 311. When the limiting rod 313 rotates 90 degrees, the support rod 312 also rotates 90 degrees. The rotating shaft 311, support rod 312, and limiting rod 313 are all made of high-strength, corrosion-resistant metal.

[0031] Furthermore, the rotating mechanism 4 includes a rotating seat 41 rotatably sleeved on the bottom of the adjusting rod 33; a limiting seat 42 is provided above the rotating seat 41 to prevent the rotating seat 41 from slipping; and the hanging ring 2 is connected to the bottom of the rotating seat 41.

[0032] The hanging ring 2 is welded to the rotating seat 41. The diameter of the limiting seat 42 is larger than the diameter of the rotating seat 41, and it is welded to the rotating seat 41. When the rope rotates, the rotating seat 41 and the limiting seat 42 will rotate synchronously.

[0033] Furthermore, the sleeve 1 is provided with a plurality of slots 11 for engaging the corresponding support rod 312; the sleeve 1 is provided with a threaded groove 12 that engages with the adjusting rod 33.

[0034] Working principle: When in use, insert the sleeve 1 into the reserved hole, hold the sleeve 1 with one hand, and rotate the adjusting rod 33 through the handwheel 34 with the other hand. At this time, the adjusting rod 33 moves upward, causing the limiting block 32 to rise. The limiting block 32 pushes the limiting rod 313, causing the rotating shaft 311 to rotate and drive the support rod 312 to rotate outward. As the limiting block 32 continues to rise, its inclined surface continues to push the limiting rod 313 until the limiting rod 313 rotates 90 degrees. The limiting block 32 reaches its limit. At this time, multiple support rods 312 rotate to 90 degrees at the same time and unfold, thus supporting the space above the reserved hole. At the same time, the adjusting rod 33 is locked to the inside of the sleeve 1 by threads. The outer wall of the frustum structure of the limiting block 32 blocks the limiting rod 313, which can prevent the support rod 312 from retracting. After use, rotate the adjusting rod 33 in the opposite direction so that the adjusting rod 33 and the limiting block 32 move down synchronously, releasing the fixation of the limiting rod 313. Then pull down the sleeve 1, and the wall of the pre-drilled hole will press against the support rod 312, causing the support rod 312 to retract, and the device can be removed.
