[0020] like Figures 1 to 5 As shown, a climbing safety belt comprises a safety suit, wherein the safety suit 1 comprises a shoulder strap 11, a leg strap 12, a waist protection belt 13 and a connecting box 14, wherein the shoulder strap 11, the leg strap 12 and the waist protection belt 13 are hinged on the connecting box 14, wherein the connecting box 14 has a cavity, wherein an automatic retractor is arranged in the cavity; the connecting box 14 is connected to a base 2 through a retractable belt, wherein the base 2 abuts against the connecting box 14; wherein the retractable belt is wound on the automatic retractor; wherein the base 2 is detachably connected to a safety belt 3, wherein the safety belt 3 is connected to the waist protection belt 13 through a safety rope 4. A fixing rod is arranged in the connecting box 14, wherein the shoulder strap 11, the leg strap 12 and the waist protection belt 13 are rotatably connected to the fixing rod respectively, wherein the shoulder strap 11 has two, the leg strap 12 has two, and the waist protection belt 13 has two; wherein each shoulder strap 11 is adapted to the leg strap 12, and the two waist protection belts 13 are adapted to each other. The base 2 is provided with a locker, and the retractable belt is inserted into the locker. The technical worker wears the safety clothing 1 and puts the safety belt 3 on the electric pole. When it is necessary to continue climbing up, the technical worker adjusts the radius of the safety belt 3 at any time to make the safety belt 3 adapt to the shape of the electric pole, which is narrow at the top and wide at the bottom. The technician adjusts the angle and distance between the body and the electric pole by controlling the retractable belt, so that the technician is in a more suitable working environment. If an accident occurs, the safety belt 3 will be subjected to a sudden pulling force. At this time, the locker will lock the safety belt 3, and the automatic retractor will not rotate, preventing the safety belt 3 from further stretching, thereby protecting the technician. Since the safety belt 3 is adapted to the electric pole, the technician's descent height will be reduced, preventing unnecessary panic and increasing the danger for the technician.
[0021] The safety belt 3 includes a disassembly block 31, a fixed portion 32 and a telescopic portion 33. The fixed portion 32 is fixedly connected to the two ends of the disassembly block 31 respectively. The fixed portion 32 has a accommodating cavity, and the telescopic portion 33 is located in the accommodating cavity. One end of the telescopic portion 33 is connected to the fixed portion 32 through a first telescopic spring, and the first telescopic spring is connected to the accommodating cavity. The other end of the telescopic portion 33 is inserted into the fixed portion 32 on the other side. The fixed part 32 is provided with a locking buckle 34, and the telescopic part 33 is provided with a plurality of limiting buckles 35. The limiting buckles 35 are evenly arranged on the telescopic part 33, and 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, the locking block 344 is connected to the torsion spring 343, and the locking block 344 is adapted to the limiting buckle 35. When the technician climbs up, the technician controls the fixed part 32 with his left hand and the telescopic part 33 with his right hand, so that the telescopic part 33 is inserted into the fixed part 32, and the locking block 344 is abutted against the limiting buckle 35 to prevent the first telescopic spring from shrinking the telescopic part 33. When the technician needs to move downward, the technician controls the handle 341 with his right hand to rotate the rotating rod 342, and the rotating rod 342 rotates the torsion spring 343, 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, thereby increasing the diameter of the safety belt 3.
[0022] The disassembly block 31 is connected to the base 2 through a disassembly assembly, and the disassembly assembly includes a push button 311, and four telescopic groups are hinged on the push button 311, and the four telescopic groups are evenly distributed on the push button 311 along the axial direction; each telescopic group includes a telescopic tongue 312, a hinge rod 313 and a connecting rod 314, and the telescopic tongue 312 is connected to the hinge rod 313 through a second telescopic spring 315. An articulated seat is provided on the push button 311, and the articulated rod 313 is hinged on the articulated seat; the connecting rod 314 passes through the articulated rod 313 and is rotatably connected to the base 2. Since the service life of the safety belt 3 and the safety clothing 1 is different, pressure can be applied to the push button 311. During the process of the push button 311 descending, the push button 311 will drive the hinge rod 313 to rotate, and the hinge rod 313 will shrink the telescopic tongue 312 through the second telescopic spring 315. After the disassembly block 31 is placed in the base 2, the push button 311 is released, and the reset spring under the push button 311 will make the push button 311 rise. At the same time, the hinge rod 313 rotates, and the hinge rod 313 will extend the telescopic tongue 312 through the second telescopic spring 315. The telescopic tongue 312 is stuck in the base 2, and the replacement of the safety belt 3 or the safety clothing 1 can be completed.
[0023] The waist protection belt 13 is provided with a first connecting ring 131, and the fixing part 32 is provided with a second connecting ring 132. The first connecting ring 131 and the second connecting ring 132 are connected by a safety rope 4; the two ends of the safety rope 4 are respectively connected with safety buckles 133. The limit buckle 35 is fixed obliquely on the telescopic part 33, and the height of the near locking buckle 34 end of the limit buckle 35 is lower than the far locking buckle 34 end. When the safety belt 3 is damaged or broken, the safety rope 4 will provide support for the technical worker to prevent the technical worker from having an accident. The safety rope has a margin to facilitate the technician to carry out slight activities at a high place.
[0024] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
