Abstract
Description
Technical Field
[0001] The utility model relates to the field of building construction safety, in particular to a safety belt for high-altitude operations in building construction. Background Art
[0002] Aerial work safety belts are important personal protective equipment used to prevent workers from falling. Three-point safety belts make it difficult for rescuers to directly pull a person out of a fall, as the belt could potentially fall off the wearer during the rescue process. Therefore, a five-point safety belt design is now commonly used, securing the wearer by attaching it to the legs. When a five-point safety belt is pulled upward, the leg straps are stressed, causing the leg straps to bind around the crotch, potentially causing injury to the wearer. Utility Model Content
[0003] The purpose of the utility model is to provide a safety belt for high-altitude work in construction to solve the above technical problems.
[0004] To achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a safety belt for high-altitude work in construction, comprising a waist belt, a shoulder strap, a shoulder strap, a D-shaped ring, a chest strap, an adjustment buckle, a connecting strap, a leg strap, and a crotch adjustment strap. The left and right parts of the top of the waist belt are respectively connected to the shoulder straps, the left and right ends of the shoulder strap are respectively connected to the rear of the shoulder strap, the D-shaped ring is installed on the rear end of the shoulder strap, the left and right ends of the chest strap are respectively connected to the front of the shoulder strap, the adjustment buckle is respectively installed on the middle part of the front end of the waist belt and the chest strap, the connecting strap is respectively connected to the left and right parts of the bottom end of the waist belt, the leg straps are respectively connected to the bottom of the left and right connecting straps, and the crotch adjustment strap connects the left and right leg straps.
[0005] Based on the above technical solution, the crotch adjustment strap includes an adjustment strap, a pedal, a strap, and a sliding hole. The left and right ends of the adjustment strap respectively pass downward through the inside of the leg strap, the inner ends of the pedals are respectively fixed to the left and right ends of the adjustment strap, and the straps are respectively fixed to the outside of the top of the pedals. The sliding hole is opened on the upper part of the strap, and the strap is slidably connected to the adjustment strap through the sliding hole.
[0006] Based on the above technical solution, the pedal tightens the inner sides of the left and right leg straps downwards through the adjustment belt to protect the crotch.
[0007] Compared with the prior art, the present invention has the following advantages: the present invention connects the crotch adjustment belt between the leg straps of the five-point safety belt, and adjusts the leg straps by pedals during the falling process, thereby reducing the force on the crotch.

[0012] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0013] like Figures 1 to 3 As shown, a construction high-altitude work safety belt includes a waist belt 1, a shoulder strap 2, a shoulder strap 3, a D-shaped ring 4, a chest strap 5, an adjustment buckle 6, a connecting strap 7, a leg strap 8, and a crotch adjustment strap 9. The left and right ends of the top of the waist belt 1 are respectively connected to the shoulder strap 2, the left and right ends of the shoulder strap 3 are respectively connected to the rear of the shoulder strap 2, the D-shaped ring 4 is installed on the rear end of the shoulder strap 3, the left and right ends of the chest strap 5 are respectively connected to the front of the shoulder strap 2, the adjustment buckle 6 is respectively installed at the middle of the front end of the waist belt 1 and the chest strap 5, the connecting strap 7 is respectively connected to the left and right parts of the bottom end of the waist belt 1, the leg strap 8 is respectively connected to the bottom of the left and right connecting straps 7, and the crotch adjustment strap 9 connects the left and right leg straps 8.
[0014] The crotch adjustment belt 9 includes an adjustment belt 10, a pedal 11, a strap 12, and a sliding hole 13. The left and right ends of the adjustment belt 10 respectively pass downward through the inside of the leg strap 8. The inner ends of the pedal 11 are respectively fixed to the left and right ends of the adjustment belt 10. The strap 12 is respectively fixed to the outside of the top end of the pedal 11. The sliding hole 13 is opened on the upper part of the strap 12, and the strap 12 is slidably connected to the adjustment belt 10 through the sliding hole 13.
[0015] The pedal 11 tightens the inner sides of the left and right leg straps 8 downwards through the adjusting belt 10 to protect the crotch.
[0016] The working principle of the present invention is as follows: when the wearer falls, the outer side of the leg strap 8 acts on the waist belt through the connecting belt 7, bearing the overall weight of the wearer, and the inner side of the leg strap 8 is pulled upward and tightened towards the crotch. At this time, the leg strap 8 is adjusted during the falling process through the foot pedal 11 to reduce the force on the crotch.
[0017] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, based on the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, replacements and variations made to the implementation methods are still within the scope of protection of the present invention.
