Description

Technical Field

[0001] The utility model relates to the field of high-altitude operation safety products, in particular to a high-altitude operation buffer safety belt. Background Art

[0002] Aerial work safety belts are important safety protection equipment for aerial work. In the event of an accidental fall during aerial work, the aerial work safety belt will bear the weight of the person, preventing the person from falling to death.

[0003] In the event of an accidental fall, since the weight of the human body is completely borne by the aerial work safety belt, the impact of the fall causes the aerial work safety belt to exert a greater force on the human body, so there is a need to avoid buffering.

[0004] The traditional buffering method is to thicken the part worn by the human body, but the buffering effect of this method is not ideal. It is necessary to optimize it on this basis. The existing structure that buffers by improving the suspension belt also has an unsatisfactory buffering effect. Therefore, it is necessary to develop a high-altitude work buffer safety belt with better buffering effect. Utility Model Content

DETAILED DESCRIPTION

[0026] 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.

[0027] See also Figures 1 to 5 In an embodiment of the present invention, a high-altitude work buffer safety belt 100 includes: a wearing belt 10 worn on the human body and a suspension belt 20 connected to the wearing belt 10.

[0028] Both ends of the suspension belt 20 are provided with hooks 201. One hook 201 is used to be fixed to a safe position. The other hook 201 is fixed to the wearing belt 10. When a fall occurs, the human body's gravity is transferred to a safe position by the high-altitude work buffer safety belt 100.

[0029] The suspension strap 20 includes a primary buffer strap 21 and a secondary buffer strap 22. The primary and secondary buffer straps 21 and 22 are connected as a single unit. The primary buffer strap 21 is a complete nylon webbing. The nylon webbing is formed with a number of webbing buffer sections 211. These sections are formed by folding the nylon webbing in a Z-shape and sewing it together. During a fall, the stitching of the Z-shaped nylon webbing breaks, causing the Z-shaped fold to unfold, providing cushioning.

[0030] The secondary buffer zone 22 includes several break buffer structures 221. These break buffer structures 221 include metal break links 2211 and metal connecting links 2212. The metal break links 2211 are composed of several interlinked fixed links 2201 and at least one break link 2202. The metal connecting links 2212 are composed of multiple interlinked fixed links 2201.

[0031] The broken link 2202 is located in the middle of the metal broken link belt 2211. Both ends of the broken link 2202 are fixed links 2201.

[0032] The metal connecting link 2212 is longer than the metal breaking link 2211. The two ends of the metal connecting link 2212 are connected to the fixed links 2201 at both ends of the metal breaking link 2211. The fixed links 2201 are welded end-to-end from a first metal rib to form a complete ring. The breaking link 2202 is formed by bending a second metal rib to form a ring with a breaking notch. The size of the breaking notch is smaller than the diameter of the first metal rib. The diameter of the second metal rib is smaller than the diameter of the first metal rib.

[0033] During a fall, the broken link 2202 deforms and breaks under stress to achieve buffering, and the broken buffer structure 221 bears the human body's weight through the metal connecting chain 2212 .

[0034] In a specific embodiment, the breakable link 2202 is bent into a 6-shape. The bottom of the 6-shape of the breakable link 2202 is welded to form a closed loop. The top of the 6-shape forms a ring with a broken notch. The top and bottom of the 6-shape are respectively connected to two fixed links 2201.

[0035] As a preferred embodiment, to prevent the breakable links 2202 from falling off, a metal breakable link 2211 has one or two breakable links 2202. When a metal breakable link 2211 has one breakable link 2202, it breaks through the breakage notch and remains attached to one fixed link 2201. When a metal breakable link 2211 has two breakable links 2202, the two breakable links 2202 with the breakage notch are linked together. In this case, if a break occurs, the two breakable links 2202 remain attached to two different fixed links 2201.

[0036] As an optional embodiment, the number of broken links 2202 of a metal broken chain belt 2211 can be set to multiple, and there is a risk of falling from a height. On this basis, an auxiliary rope can be added to connect the broken links 2202 that may fall to avoid falling objects from a height.

[0037] As an optional embodiment, different from Figure 5 The 6-shaped middle broken link 2202, reference Figure 6 The broken link is bent into an 8-shape. The upper and lower loops of the 8-shape are welded together to form a closed ring, while the other loop is a ring with a broken notch. The upper and lower loops of the 8-shape are connected to two fixed links respectively.

[0038] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
