[0027] Example 1

[0028] Reference Figures 1-4 This is the first embodiment of the present utility model. This embodiment provides a padlock mechanism, including a lock head assembly 1 including a hook 11, a hook tongue 12 disposed on the end side of the hook 11, an adsorption base 13 disposed on the rear end of the hook 11, a fixing member 14 that passes through the axis of the adsorption base 13, and a hinge shaft 15 disposed on the end of the hook 11.

[0029] The adsorption assembly 2 includes a locking disc 21 hinged to one side of the hinge shaft 15, and a hanging plate 22 disposed inside the adsorption base 13.

[0030] As an optional embodiment, both the adsorption base 13 and the locking disc 21 are disc-shaped.

[0031] As an optional embodiment, the adsorption base 13 includes a positioning hole 131 that extends through its axis.

[0032] As an optional embodiment, the adsorption base 13 further includes a snap-fit ​​plate 132 disposed on the outside of the hanging piece 22, hinge seats 133 disposed on both sides of the end of the snap-fit ​​plate 132, and a snap-fit ​​seat 134 disposed at the bottom of the snap-fit ​​plate 132.

[0033] As an optional embodiment, the lock disc 21 includes a connecting end 211 disposed on the hinge shaft 15, a slot 212 disposed at the rear end of the connecting end 211, a through hole 213 disposed at the axis of the lock disc 21, and a fastener 214 disposed at the bottom of the lock disc 21.

[0034] As an alternative embodiment, fastener 214 engages with snap-fit ​​connector 134.

[0035] As an optional embodiment, the positioning hole 131 and the through hole 213 are axially aligned.

[0036] As an optional embodiment, the adsorption assembly 2 also includes a spring 23 disposed inside the card holder 132.

[0037] As an optional embodiment, the hanging piece 22 is connected to the adsorbed surface through a slot 212;

[0038] Furthermore, the hanging plate 22 is adsorbed through a strong magnetic adsorption layer A, a vacuum adsorption layer B, and an adhesive layer C.

[0039] In this embodiment, the locking assembly 1 is made of high-strength alloy steel and undergoes a special heat treatment process, giving it extremely high strength and toughness. The hook 11 is designed in an arc shape, resembling a hanging ear, with a central circular attachment point for connecting to the worker's safety belt or fall arrest rope. Its inner surface has anti-slip textures to increase friction with the connecting rope or safety buckle, preventing accidental disengagement. The bottom surface is an adsorption base 13, which is ring-shaped with a central mounting position for the adsorption assembly 2. A fixed safety buckle can be added according to the actual working environment to ensure the safety of the connection.

[0040] The hook 11 serves as the main support structure and has a two-section design. The longer bottom section is the primary support, while the shorter end is a hinged hook tongue 12. The hook tongue 12 is elastically hinged to one end of the hook 11 via a torsion spring, preventing accidental disengagement of the connecting rope or safety buckle. An adsorption base 13 protrudes from the rear end of the hook 11. The adsorption base 13, through a fixing member 14 and an adsorption assembly 2, secures the hook 11 to the adsorption surface.

[0041] In this embodiment, the back of the adsorption base 13 is provided with a retaining plate 132, and the inside of the retaining plate 132 has a circular groove. The end of the adsorption base 13 is provided with two sets of hinge seats 133. The hinge seats 133 have holes in their axial centers, and a set of hinge shafts 15 are hinged in the holes. The hinge shafts 15 can hinge the adsorption component 2 to the retaining plate 132.

[0042] The adsorption assembly 2 consists of a locking disc 21 and a hanging piece 22 on the inner side of the locking disc 21. The end of the locking disc 21 protrudes as a connecting end 211, which can be snapped into the inner side of the hinge seat 133, and the connecting end 211 and the hinge seat 133 are connected together through the hinge shaft 15.

[0043] In this embodiment, the hinge shaft 15 is used to connect the hook 11 and the adsorption assembly 2. It is made of stainless steel, which has good corrosion resistance and fatigue resistance. The hinge shaft 15 consists of a bolt and a nut at one end. By aligning the connecting end 211 and the hinge seat 133 axis together, the bolt in the hinge shaft 15 is tightened onto the nut to achieve a fixed connection.

[0044] In this embodiment, the card plate 132 is equipped with a shock-absorbing spring 23. When the hanging piece 22 is impacted by an external force, the shock-absorbing spring 23 can play a buffering role, reducing damage to the overall structure and connection points of the hanging piece 22.

[0045] In this embodiment, the locking disc 21 is disc-shaped with multiple sets of slots 212 on its surface. Hanging pieces 22 with the same shape as the slots 212 can be provided inside the slots 212 and inside the snap-fit ​​disc 132. Different hanging pieces 22 can be provided in each slot 212 so that the hanging pieces 22 can be directly adsorbed onto the adsorption surface. The bottom of the locking disc 21 is a fastener 214, which can be snapped together with the snap-fit ​​base 134 to lock the locking disc 21 onto the snap-fit ​​disc 132.

[0046] When the fastener 214 can be engaged with the locking base 134, the through hole 213 on the axis of the locking disc 21 coincides with the axis of the positioning hole 131 on the axis of the locking disc 132. This allows the fastener 14 to be connected through the hook 11 and the adsorption assembly 2, connecting with the hook 11 and the adsorption base 13's adsorption surface, and radially bearing the tension of the safety belt or safety rope. The fastener 14 adopts an expansion bolt mechanical locking structure design, which has reliable locking performance and prevents disengagement accidents caused by insufficient suction force of the hanging plate 22.

[0047] In this embodiment, the hanging plate 22 consists of a strong magnetic attraction layer A, a vacuum adsorption layer B, and an adhesive layer C. The strong magnetic attraction layer A uses a high-performance neodymium iron boron magnet, which can firmly adhere to the surface of metals such as steel.

[0048] Vacuum adsorption layer B consists of a rubber suction cup and an air extraction device. The rubber suction cup is made of a soft material and has good sealing properties. The air extraction device can be operated manually or connected to an external air source to extract the air from the suction cup, creating a vacuum state, thereby adsorbing onto smooth surfaces such as glass and ceramic tiles.

[0049] The adhesive layer C uses high-strength, weather-resistant industrial adhesive to cover the bottom of the adsorption base. When encountering surfaces such as concrete or wood that are not suitable for magnetic adsorption and vacuum adsorption, the hanging strip can be pasted onto the surface by peeling off the protective film of the adhesive layer.

[0050] The three adsorption methods can be flexibly selected according to different working environments. The adsorption base is equipped with an adsorption force detection sensor, which can monitor the magnitude of the adsorption force in real time and send the data to the warning device carried by the operator through a wireless signal transmission module.

[0051] When using the device, before working at height, operators should select the appropriate adsorption method for the card plate 132 based on the material of the work surface. For metal surfaces, simply bring the strong magnetic layer A of the hanging plate close to the surface, and the magnet will automatically attract it. For smooth surfaces, the vacuum suction device of the vacuum adsorption layer B can be used to allow the suction cup to adhere. For other surfaces, the adhesive layer C can be used for pasting.

[0052] After adsorption is complete, the adsorption force detection sensor starts working, monitoring the adsorption force and transmitting data. The operator connects the safety belt or fall arrestor rope via the safety buckle hook 11, which is reliably locked by the fixing member 14. During operation, if the adsorption force drops below the safety threshold, the warning device will sound an alarm, allowing the operator to take timely measures, such as changing the adsorption position or checking the adsorption status. In the event of an accidental fall, the high-strength materials of the hook 11, hinge shaft 15, and adsorption base 13, as well as the shock-absorbing spring 23 within the hinge shaft 15, can withstand significant impact forces. Simultaneously, the mechanical locking design of the expansion bolts in the fixing member 14 ensures that the operator will not be dislodged from the fall arrestor system.

[0053] Reference Figures 1-5 This embodiment provides a height climbing and fall prevention device, including a connecting unit 3, including a first hanging head 31, a steel cable 32 disposed on one side of the first hanging head 31, and a second hanging head 33 disposed on the other side of the steel cable 32.

[0054] In this embodiment, the operator first checks whether each component of the padlock mechanism is intact, including whether the automatic locking device of the hook 11 is flexible, whether the three adsorption layers of the adsorption base 13 are normal, and whether the mechanical lock and electronic lock of the safety lock are reliable.

[0055] Determine the adsorption method of the adsorption base 13 based on the material of the surface to be worked on. If it is a metal surface, ensure that the surface of the strong magnetic layer A is free of impurities; if it is a smooth surface, check whether the rubber suction cup of the vacuum adsorption layer B is damaged and prepare the air extraction device; if the adhesive layer C is used, clean the dust and oil on the working surface in advance and peel off the protective film of the adhesive layer.

[0056] Install the hanging plate 22 on the working surface according to the selected adsorption method. For magnetic and vacuum adsorption methods, ensure that the adsorption is firm and observe whether the initial data of the adsorption force detection sensor is normal.

[0057] Connect the end of the worker's safety belt or fall arrest rope to the round hole of the hook 11. For the adsorption surface that can be fitted with a safety locking buckle, first use an impact drill to drill a hole of the appropriate size on the adsorption surface. Then align the fixing part 14 on the hook 11 with the hole, and then insert the safety locking buckle into the hole. Tighten the nut to make the bolt, expansion tube, mounting part and fixing body tighten into one. Pull the main hook forcefully to check whether the connection is secure.

[0058] During the work at height, the workers should pay attention to whether the warning equipment will sound an alarm. If an alarm sounds, the work should be stopped immediately and the adsorption force of the adsorption base 13 should be checked. If the adsorption force is insufficient, the adsorption method should be changed or the installation position of the hanging plate should be changed according to the actual situation.

[0059] After the work is completed, first disconnect the safety belt or fall arrest rope from the hook 11, and then disassemble according to the adsorption method. For magnetic adsorption, directly apply force to remove the hanging plate from the metal surface; for vacuum adsorption, operate the vacuum device to restore normal pressure inside the suction cup before removing it; for adsorption with adhesive layer C, carefully peel the hanging plate 22 from the working surface using a special solvent or tool. For those with safety locking buckles, open the fixing nuts of the expansion bolts and peel the hanging plate 22 from the working surface. After disassembly, clean and tidy the hanging plate 22, and check all parts for damage for future use.

[0060] In summary, this device, designed for complex high-altitude environments, especially where suitable anchor points are lacking on steel structures, utilizes a padlock mechanism to securely fix itself to surfaces of various materials. This effectively solves the problem of limited anchor points in traditional fall arrest devices, significantly improving operational safety and efficiency. Furthermore, the replaceable and adjustable mounting plates in the adsorption assembly make maintenance and replacement more convenient, greatly reducing maintenance costs and time, and further enhancing the device's practicality and economy.
