Description

Technical Field

[0001] The utility model relates to the technical field of safety belts, in particular to a five-point locking suspension safety belt for aerial workers. Background Art

[0002] A five-point safety harness consists of two shoulder straps, two waist belts, and a leg or safety belt, securing the operator to the work platform at these five points. In the event of a fall, the five-point harness quickly distributes the impact force, preventing excessive damage to a single area. This force-distribution design significantly reduces the risk of serious injury from a fall.

[0003] However, although the existing five-point safety belt plays an important role in ensuring the safety of construction workers, when workers climb or move on higher buildings, if they encounter danger and fall, the locking hook and safety rope are mostly installed on the rear side. When the workers are suspended in the air, they cannot grab the safety rope on the rear side with both hands, leaving them without a foothold and unable to adjust their body position, making it inconvenient to turn over and save themselves. This problem will bring great danger and trouble to the workers in actual high-altitude operations, and may even lead to more serious consequences due to the inability to save themselves in time. In order to solve the above problems, we propose a five-point locking suspension safety belt for workers working at heights. Utility Model Content

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-5When the worker is in the air, the auxiliary belt 3 can be pulled up by the adjusting portion 4 to tighten the auxiliary belt 3 (i.e., shorten the distance between the adjusting portion 4 and the safety rope 2). As the auxiliary belt 3 is pulled, the position of the body can be adjusted, making it convenient for both hands to grab the safety rope 2, and having a fulcrum to make it easier to perform self-rescue operations.

[0029] At the same time, the operator can also use the auxiliary belt to turn the body to a more comfortable posture so as to better observe the surrounding environment and find methods and ways to save themselves.

[0030] A locking piece 5 is provided on the adjusting part 4. When the auxiliary belt 3 is pulled through the adjusting part 4, the state of the auxiliary belt 3 can be fixed by the provided locking piece 5 so that it will not slip off under the action of the human body's gravity, thereby fixing the position of the human body.

[0031] The adjusting portion 4 includes a gear 41 and teeth 42. The teeth 42 are fixed to the side wall of the auxiliary belt 3. The gear 41 and the teeth 42 are engaged. The front side of the five-point safety belt body 1 is provided with a rotating member 43 connected to the gear 41. The rotating member 43 can be used to rotate the gear 41, and then the auxiliary belt 3 is driven to move through the teeth 42, so that the auxiliary belt 3 is tightened, that is, the distance between the adjusting portion 4 and the safety rope 2 is shortened.

[0032] The rotating member 43 is connected to the locking member 5 so that the gear 41 does not rotate, thereby fixing the state of the auxiliary belt 3 .

[0033] Specifically, a drive box 44 is provided on the front side of the five-point safety belt body 1, the auxiliary belt 3 passes through the drive box 44, the rotating member 43 includes a rotating wheel 431, the rotating rod portion of the rotating wheel 431 passes through the side wall of the driving box 44 and is rotatably connected thereto, the handwheel portion of the rotating wheel 431 is arranged on the outside of the driving box 44, and a first bevel gear 432 fixedly connected to the rotating rod portion of the rotating wheel 431 is provided inside the driving box 44. The gear 41 is coaxially fixed with a second bevel gear 433 through a shaft, and the first bevel gear 432 is meshed with the second bevel gear 433;

[0034] When the operator needs to pull the auxiliary belt 3, they simply turn the wheel 431. The rotation of the wheel 431 drives the first bevel gear 432 to rotate, which in turn, through meshing with the second bevel gear 433, drives the gear 41 to rotate. The rotation of the gear 41, through the engagement with the teeth 42, pulls the auxiliary belt 3, thereby tightening the auxiliary belt 3 and adjusting the body's position. During the adjustment process, the locking member 5 locks the wheel 431, which in turn stops the first bevel gear 432 and the second bevel gear 433, and ultimately stops the gear 41, ensuring the stability of the auxiliary belt 3 and the safety of the operator.

[0035] Specifically, the locking member 5 includes a ratchet 51 connected to the rotating member 43. A rotatable pawl 52 is provided within the drive box 44 and is adapted to fit the ratchet 51. A first elastic member, which can be a torsion spring, is provided on the pawl 52. When the rotating member 43 drives the ratchet 51 to rotate, the pawl 52, under the action of the first elastic member, can tightly clamp the ratchet 51 to prevent the ratchet 51 from rotating in the opposite direction.

[0036] This effectively locks the auxiliary belt 3, preventing it from loosening or slipping due to factors such as the weight of the body during the operator's body adjustments. Furthermore, the provision of the first elastic member ensures a tight and reliable connection between the pawl 52 and the ratchet 51, thereby enhancing the safety and stability of the safety belt.

[0037] Specifically, a sliding frame 53 is slidingly provided on the inner wall of the drive box 44, and a shaft is fixed to the sliding frame 53. The pawl 52 is rotatably connected to the shaft on the sliding frame 53. A first elastic member is provided on the shaft of the sliding frame 53. A pull rod 54 is fixed to one side of the sliding frame 53. The pull rod 54 passes through the side wall of the drive box 44 and is slidably connected thereto, so that the pull rod 54 can be operated outside the drive box 44. When it is necessary to release the lock on the auxiliary belt 3, the pawl 52 can be disengaged from the ratchet 51 by pulling the pull rod 54, thereby allowing the rotating member 43 to rotate in the opposite direction to adjust the length of the auxiliary belt 3 or perform other operations.

[0038] The pull rod 54 is equipped with a second elastic member 55 connected to the drive box 44. When the pull rod 54 is pulled, the second elastic member 55 deforms, generating a certain elastic force. When the external force disappears, the elastic force of the second elastic member 55 causes the pull rod 54 to return to its initial position, thereby driving the sliding frame 53 and the pawl 52 back to their working positions, ensuring that the pawl 52 can continue to engage with the ratchet 51, effectively locking the auxiliary belt 3. This design not only facilitates the operator's unlocking when needed, but also ensures the safety performance of the seat belt under normal circumstances.

[0039] Specifically, a pressure plate 6 is provided on the inner top wall of the driving box 44, and the auxiliary belt 3 is provided between the pressure plate 6 and the gear 41;

[0040] The pressure plate 6 can exert a certain degree of pressure on the auxiliary belt 3, ensuring a closer and more stable contact between the auxiliary belt 3 and the gear 41. When the gear 41 rotates, the presence of the pressure plate 6 prevents the auxiliary belt 3 from deflecting or loosening, and can be more accurately driven by the gear 41.

[0041] At the same time, the pressure plate 6 can also limit the range of movement of the auxiliary belt 3, so that it always remains on a relatively stable path during the pulling process, thereby improving the reliability and safety of the safety belt.

[0042] In addition, the arrangement of the pressure plate 6 can also protect the auxiliary belt 3 to a certain extent, reduce the wear thereof caused by friction with other components, and extend the service life of the safety belt.

[0043] Specifically, auxiliary rollers 7 are rollingly mounted on the sidewalls of the pressure plate 6. These rollers are rollingly connected to the sidewalls of the auxiliary belt 3. This rolling connection significantly reduces friction between the auxiliary belt 3 and the pressure plate 6 during movement, allowing the auxiliary belt 3 to move more smoothly. When the auxiliary belt 3 is pulled or adjusted, the auxiliary rollers 7 can roll freely with the movement of the belt 3, avoiding the inconvenience caused by frictional resistance during seat belt use.

[0044] At the same time, the auxiliary roller 7 can also support and guide the auxiliary belt 3, ensuring that the auxiliary belt 3 runs in the correct position and preventing it from deviating or twisting.

[0045] In addition, the rolling connection of the auxiliary roller 7 can also reduce the degree of wear of the auxiliary belt 3, extend its service life, and improve the overall reliability and durability of the safety belt.

[0046] Specifically, the five-point safety belt body 1 includes a shoulder belt 11, and the auxiliary belt 3 is fixed to the shoulder belt 11 by a buckle 8. When the auxiliary belt 3 is not in use, the auxiliary belt 3 is fixed to the shoulder belt 11 by the buckle 8 to prevent the auxiliary belt 3 from being scattered. When the operator is suspended in the air, the operator can quickly release the fixed state between the auxiliary belt 3 and the shoulder belt 11 through the buckle 8 to adjust the auxiliary belt 3. The buckle 8 connection operation is simple and convenient.

[0047] In addition, the buckle 8 can be disassembled as needed to facilitate operations such as cleaning, maintenance and replacement of parts of the safety belt.

[0048] Specifically, the shoulder straps 11 on both sides cross and form a fall protection connection point, to which the back protection pad 9 is fixed. The cross-arrangement of the shoulder straps 11 on both sides can increase the stability of the safety belt during use. If the user falls or encounters an accident, the crossed shoulder straps 11 can better disperse the impact force and reduce damage to the user's body.

[0049] Secondly, the fall protection connection point is a key part, and its strength and reliability are of paramount importance. By fixing the back protection pad 9 at this connection point, the strength of the connection point can be increased, thereby improving the overall safety of the safety belt.

[0050] On the other hand, the back protection pad 9 can protect the user's back to a certain extent and reduce the impact on the back in the event of an accident.

[0051] In addition, the back protection pad 9 can also improve the comfort of the user wearing the safety belt, and avoid the hard connection point directly contacting the user's back and causing discomfort.
