[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0029] Please refer to Figures 1-2 A semi-waist safety belt 100, as described in one embodiment, includes a shoulder strap 10 for wearing on the shoulders of an electrical worker; and a waist strap 20 connected below the shoulder strap 10 and worn on the waist and abdomen of the electrical worker. The waist strap 20 includes a strap body 21, a first strap assembly 22, and a second strap assembly 23. The strap body 21 has an opening, the first strap assembly 22 is connected to one end of the opening, and the second strap assembly 23 is connected to the other end of the opening.
[0030] Please see Figure 2 The first tie assembly 22 includes a first reel 221, a first tie 222, and a first buckle 223. The first reel 221 is rotatably disposed on the tie body 21. The first tie 222 is wound around and installed on the outside of the first reel 221. The first buckle 223 is connected to the end of the first tie 222. The second tie assembly 23 includes a second reel 231, a second tie 232, and a second buckle 233. The second reel 231 is rotatably disposed on the tie body 21. The second tie 232 is wound around and installed on the outside of the second reel 231. The second buckle 233 is connected to the end of the second tie 232. The second buckle 233 can be locked or separated from the first buckle 223.
[0031] As is easily understood, the main body 21 of the strap is a semi-closed ring structure. When the first buckle 223 and the second buckle 233 are separated, the waist strap 20 maintains an open structure, making it convenient for power workers to put on or take off the strap. When the first buckle 223 and the second buckle 233 are locked, the waist strap 20 forms a closed ring structure, which can tighten the waist and abdomen, providing protection for power workers.
[0032] Implementing the embodiments of this utility model will have the following beneficial effects:
[0033] When power workers use the half-waist safety belt 100 of this solution, they first put the shoulder strap 10 on their shoulders, and then loop the waist strap 20 from the back to the front abdomen around their waist. Depending on the waist and abdomen size of different power workers, by pulling the first buckle 223 and the second buckle 233 closer or further apart, the first strap 222 and the second strap 232 synchronously drive the first winding shaft 221 and the second winding shaft 231 to rotate, thereby enabling the first strap 222 to be wound up to shorten its length or unwound to increase its length. By adjusting the length of the first strap assembly 22 and the second strap assembly 23, the appropriate lengths can be obtained. Finally, the first buckle 223 and the second buckle 233 are locked together to complete the wearing operation of the half-waist safety belt 100. Compared with the existing technology, by using the winding or unwinding rotation of the first belt shaft 221 and the second belt shaft 231, the lengths of the first strap 222 and the second strap 232 can be flexibly adjusted so that the first buckle 223 and the second buckle 233 can be connected. The tightness adjustment operation is convenient and labor-saving, which greatly improves the wearing efficiency and user experience of the half-waist safety belt 100.
[0034] In one embodiment, one of the first latch 223 and the second latch 233 is configured as a hook, and the other of the first latch 223 and the second latch 233 is configured as a latch, with the hook and latch being detachably engaged. This detachable engagement of the hook and latch simplifies the installation and disassembly structure and method of the first latch 223 and the second latch 233, resulting in high connection reliability and improving the wearing efficiency of the half-waist safety belt 100.
[0035] Preferably, in this application, the two opposite sides of the hook in the thickness or width direction are respectively provided with a first mounting surface and a second mounting surface, a first hook portion is provided on the first mounting surface, and a second hook portion is provided on the second mounting surface.
[0036] When one of the first hook and the second hook engages with the latch hook, the other of the first hook and the second hook engages with the latch to avoid contact.
[0037] The hook is equipped with both a first hook and a second hook, so that no specific alignment operation is required when the hook and the buckle are engaged. Either the first hook or the second hook can be randomly engaged with the buckle to form a buckle column, which makes the installation more flexible and helps to improve the wearing efficiency of the half-waist safety belt 100.
[0038] Please see Figure 2 In another embodiment, the first lacing assembly 22 further includes a first fixing post 224, one end of the first lacing 222 away from the first reel shaft 221 is mounted on the first fixing post 224, the first latch 223 is fixed on the first fixing post 224, and the two opposite ends of the first fixing post 224 extend to opposite sides in the width direction of the first lacing 222.
[0039] Similarly, the second tie assembly 23 also includes a second fixing post 234. One end of the second tie 232 away from the second reel shaft 231 is mounted on the second fixing post 234. The second buckle 233 is fixed on the second fixing post 234. The two opposite ends of the second fixing post 234 extend to the opposite sides of the width direction of the second tie 232.
[0040] The first fixing post 224 and the second fixing post 234 are made of rigid material, providing a gripping part for labor operations. Compared with directly pulling the soft first strap 222 and the second strap 232, it is easier to control the position of the hook and the slot, thereby controlling the alignment accuracy of the two, making the hook more accurate and easier to insert into the slot, and improving the effectiveness of the assembly operation of the first strap assembly 22 and the second strap assembly 23.
[0041] Furthermore, at least one end of the first tape reel 221 is provided with a first rotating post 225 protruding from the axial direction, and a first torque member 226 is fitted on the outside of the first rotating post 225, and the first torque member 226 abuts against the strap body 21.
[0042] Similarly, at least one end of the second tape reel 231 is provided with a second rotating post 235 protruding from the axial direction, and a second torque member 236 is fitted on the outside of the second rotating post 235, and the second torque member 236 abuts against the strap body 21.
[0043] When the first buckle 223 and the second buckle 233 are pulled closer together, the lengths of the first strap 222 and the second strap 232 are simultaneously stretched. The first reel shaft 221 and the second reel shaft 231 rotate, thereby compressing the first torque member 226 and the second torque member 236 respectively to generate torsion spring deformation. The first torque member 226 and the second torque member 236 accumulate torsional potential energy. Immediately after the first buckle 223 and the second buckle 233 are fastened, the first torque member 226 and the second torque member 236 have a rebound force to release torsional potential energy, so as to pull the first strap 222 and the second strap 232 to move away from each other. This makes the first buckle 223 and the second buckle 233 more tightly and securely fastened together, avoiding accidental loosening that would affect the protective reliability of the half-waist seat belt 100.
[0044] Optionally, the first torque element 226 and the second torque element 236 can be, but are not limited to, a spring, a torsion spring, an elastic rope (belt), etc.
[0045] Please see Figure 1 In one embodiment of this application, the shoulder strap 10 includes a first shoulder strap 11, a second shoulder strap 12, a buckle 13, and a connecting plate 14. The first shoulder strap 11 and the second shoulder strap 12 are connected at an intersection. The connecting plate 14 is disposed at the junction of the first shoulder strap 11 and the second shoulder strap 12. One end of the buckle 13 is connected to the first shoulder strap 11, and the other end of the buckle 13 is connected to the second shoulder strap 12. The buckle 13 is provided with a quick-release buckle 15.
[0046] The connecting plate 14 connects to the junction of the first shoulder strap 11 and the second shoulder strap 12, improving the connection strength between the first shoulder strap 11 and the second shoulder strap 12, enhancing the overall structural performance and durability of the semi-waist safety belt 100. This arrangement also prevents the first shoulder strap 11 and the second shoulder strap 12 from slipping off the shoulders of the electrical worker, ensuring reliable wear. The quick-release buckle 15 on the buckle 13 facilitates the connection and disconnection of the buckle 13, making it convenient to wear the semi-waist safety belt 100.
[0047] In one embodiment, the connecting plate 14 is provided with a mounting ring for detachable assembly with the mounting hook of the fall arrestor rope. By connecting with the fall arrestor rope installed on the transmission tower, the fall arrestor rope and the half-waist safety harness 100 work together to further enhance the fall protection effect for power workers.
[0048] According to another aspect of the present invention, a climbing protection device is also provided, which includes a half-waist safety belt 100 as described in any of the above embodiments.
[0049] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
