Description

Technical Field

[0001] This utility model relates to a safety belt, specifically a climbing safety belt. Background Technology

[0002] When skilled workers perform work at heights, they must wear appropriate climbing safety harnesses to ensure their safety and operational stability. These harnesses are typically full-body or five-point harnesses, mainly composed of the harness body, safety rope, cushioning pad, and metal fittings. However, when climbing utility poles, the worker's position and height constantly change, and the pole's diameter decreases. Currently, the safety ropes used are of fixed length and cannot be adjusted to accommodate the pole's diameter. This results in a larger angle between the worker and the pole, or increased slack in the safety rope, affecting working conditions and increasing the risk of injury. Utility Model Content

[0003] The purpose of this invention is to provide a climbing safety belt that solves the problem that the length of the safety rope is fixed and cannot be changed according to the diameter of the utility pole.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A climbing safety harness includes a safety garment comprising shoulder straps, leg straps, a lumbar support belt, and a connecting box. The shoulder straps, leg straps, and lumbar support belt are hinged to the connecting box, which has a cavity containing an automatic retractor. The connecting box is connected to a base via a telescopic strap, and the base abuts against the connecting box. The telescopic strap is wound onto the automatic retractor. The base is detachably connected to a safety harness, which is connected to the lumbar support belt via a safety rope.

[0006] Furthermore, the seat belt includes a disassembly block, a fixing part, and a telescopic part. The fixing part is fixedly connected to both ends of the disassembly block, and the fixing part has a receiving cavity, in which the telescopic part is located. One end of the telescopic part is connected to the fixing part through a first telescopic spring, which is connected to the receiving cavity, and the other end of the telescopic part is inserted into the fixing part on the other side.

[0007] Furthermore, the fixed part is provided with a locking buckle, and the telescopic part is provided with multiple limiting buckles, which are evenly distributed on the telescopic part. The locking buckle is adapted to the limiting buckle. The locking buckle includes a handle, a rotating rod, a torsion spring, and a locking block. The handle is located above the fixed part, the rotating rod is fixedly connected to the handle, the torsion spring is sleeved on the rotating rod, and the locking block is connected to the torsion spring. The locking block is adapted to the limiting buckle.

[0008] Furthermore, the disassembly block is connected to the base via a disassembly assembly, which includes a pressing key connected to the base via a return spring. Four telescopic groups are hinged to the pressing key, and these groups are evenly distributed axially along the pressing key. Each telescopic group includes a telescopic tongue, a hinge rod, and a connecting rod. The telescopic tongue is connected to the hinge rod via a second telescopic spring. The pressing key is provided with a hinge seat, and the hinge rod is hinged to the hinge seat. The connecting rod passes through the hinge rod and is rotatably connected to the base.

[0009] Furthermore, the waist support belt is provided with a first connecting ring and a second connecting ring on the fixing part, and the first connecting ring and the second connecting ring are connected by a safety rope; the two ends of the safety rope are respectively connected to safety buckles.

[0010] Furthermore, the limiting buckle is fixed obliquely on the telescopic part, and the height of the near locking buckle end of the limiting buckle is lower than that of the far locking buckle end.

[0011] Furthermore, a fixing rod is provided inside the connecting box, and the shoulder strap, leg strap and waist support belt are rotatably connected to the fixing rod.

[0012] Furthermore, the base is provided with a locking device, and the telescopic strap is inserted into the locking device.

[0013] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0014] This invention features a detachable safety harness attached to a safety suit. The harness can retract as the technician ascends, and during descent, the harness radius can be increased via a locking buckle. In the event of an accident, a sudden pulling force will lock the retractable harness, preventing further descent. The retractable harness prevents disorganization and obstructed vision during work, reducing the difficulty of the task. This invention not only ensures the safety of technicians but also simplifies the work process and improves efficiency. Attached Figure Description

[0020] like Figures 1 to 5 As shown, a climbing safety harness includes a safety vest 1. The safety vest 1 includes shoulder straps 11, leg straps 12, waist belts 13, and a connecting box 14. The shoulder straps 11, leg straps 12, and waist belts 13 are hinged to the connecting box 14. The connecting box 14 has a cavity with an automatic retractor inside. The connecting box 14 is connected to a base 2 via a telescopic strap, and the base 2 abuts against the connecting box 14. The telescopic strap is wound onto the automatic retractor. The base 2 is detachably connected to a safety belt 3, which is connected to the waist belt 13 via a safety rope 4. A fixing rod is provided inside the connecting box 14. The shoulder straps 11, leg straps 12, and waist belts 13 are rotatably connected to the fixing rod. There are two shoulder straps 11, two leg straps 12, and two waist belts 13. Each shoulder strap 11 is adapted to a leg strap 12, and each of the two waist belts 13 is adapted to a waist belt 13. The base 2 is equipped with a locking device, into which the telescopic belt is inserted. The technician wears a safety vest 1 and attaches the safety belt 3 to the utility pole. When further climbing is required, the technician adjusts the radius of the safety belt 3 to fit the shape of the utility pole, making it narrower at the top and wider at the bottom. The technician controls the telescopic belt to adjust the angle and distance between their body and the utility pole, ensuring a suitable working environment. In case of an accident, the safety belt 3 will experience a sudden pulling force, at which point the locking device will lock the safety belt 3, and the automatic retractor will not rotate, preventing further stretching of the safety belt 3 and thus protecting the technician. Because the safety belt 3 is fitted to the utility pole, it reduces the technician's descent height, preventing unnecessary panic and increasing the risk of injury.

[0021] The seat belt 3 includes a disassembly block 31, a fixing part 32, and a telescopic part 33. The fixing part 32 is fixedly connected to both ends of the disassembly block 31. The fixing part 32 has a receiving cavity, and the telescopic part 33 is located in the receiving cavity. One end of the telescopic part 33 is connected to the fixing part 32 through a first telescopic spring, and the first telescopic spring is connected to the receiving cavity. The other end of the telescopic part 33 is inserted into the fixing part 32 on the other side. The fixed part 32 is provided with a locking buckle 34, and the telescopic part 33 is provided with multiple limiting buckles 35, which are evenly distributed on the telescopic part 33. The locking buckle 34 is adapted to the limiting buckle 35. The locking buckle 34 includes a handle 341, a rotating rod 342, a torsion spring 343, and a locking block 344. The handle 341 is located above the fixed part 32, the rotating rod 342 is fixedly connected to the handle 341, the torsion spring 343 is sleeved on the rotating rod 342, and the locking block 344 is connected to the torsion spring 343. The locking block 344 is adapted to the limiting buckle 35. During the process of technicians climbing, the technicians control the fixed part 32 with their left hand and control the telescopic part 33 with their right hand, so that the telescopic part 33 is inserted into the fixed part 32 and the locking block 344 abuts against the limiting buckle 35 to prevent the first telescopic spring from causing the telescopic part 33 to retract. When the technician needs to move downwards, the technician controls the handle 341 with his right hand to rotate the rotating rod 342. The rotating rod 342 causes the torsion spring 343 to rotate, and the locking block 344 on the torsion spring 343 will leave the limit buckle 35, so that the telescopic part 33 can be pulled out from the fixed part 32, increasing the diameter of the safety belt 3.

[0022] The disassembly block 31 is connected to the base 2 via a disassembly assembly. The disassembly assembly includes a pressing key 311, on which four telescopic groups are hinged. The four telescopic groups are evenly distributed along the axial direction on the pressing key 311. Each telescopic group includes a telescopic tongue 312, a hinge rod 313, and a connecting rod 314. The telescopic tongue 312 is connected to the hinge rod 313 via a second telescopic spring 315. The pressing key 311 is provided with a hinge seat, and the hinge rod 313 is hinged to the hinge seat. The connecting rod 314 passes through the hinge rod 313 and is rotatably connected to the base 2. Since the lifespans of the seat belt 3 and the safety vest 1 are different, pressure can be applied to the pressing button 311. As the pressing button 311 descends, it drives the hinge rod 313 to rotate. The hinge rod 313 retracts the telescopic tongue 312 through the second telescopic spring 315. After the disassembly block 31 is placed in the base 2, the pressing button 311 is released. The return spring under the pressing button 311 will cause the pressing button 311 to rise. At the same time, the hinge rod 313 rotates, and the telescopic tongue 312 extends through the second telescopic spring 315. The telescopic tongue 312 is locked in the base 2, thus completing the replacement of the seat belt 3 or the safety vest 1.

[0023] The lumbar support belt 13 is equipped with a first connecting ring 131, and the fixing part 32 is equipped with a second connecting ring 132. The first connecting ring 131 and the second connecting ring 132 are connected by a safety rope 4. Safety buckles 133 are connected to both ends of the safety rope 4. The limiting buckle 35 is fixed obliquely on the telescopic part 33, and the height of the near locking buckle 34 end of the limiting buckle 35 is lower than that of the far locking buckle 34 end. In the event of damage or breakage of the safety belt 3, the safety rope 4 will provide support for the technician and prevent accidents. The safety rope has a slack to facilitate minor activities by the technician at height.

[0024] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
