Abstract
Description
Technical Field
[0001] The present application relates to the technical field of safety belts, and in particular to a double-insurance safety belt for building construction. Background Art
[0002] When constructing or decorating high-rise buildings, construction workers generally need to be equipped with safety belts for protection. After fixing the safety belt on the body, the hook is connected through a safety rope and hung on the external building to prevent construction workers from falling directly to the ground and getting injured when accidentally falling from a height, greatly improving the safety of construction workers during construction.
[0003] Existing safety belts generally consist of a waist belt, a shoulder belt, and a leg belt. When a person falls from a relatively high building, due to the impact force, the safety belt will tighten sharply, which not only easily causes the safety belt to break due to the impact, but also the tightened safety belt may injure the construction worker. Utility Model Content
[0004] The purpose of the present utility model is to solve or at least alleviate the problem that the existing safety belt cannot be buffered during use. When a construction worker falls, due to the impact force, the safety belt will tighten sharply, which not only easily causes the safety belt to break due to the impact, but also the tightened safety belt may injure the construction worker.
[0005] To achieve the above purpose, the present utility model adopts the following technical solution:
[0006] A double-insurance safety belt for building construction includes a safety belt body fixed to the human body through a fixing member, and a main safety rope with one end fixedly connected to the safety belt body and the other end tied with a hook. There are also two auxiliary safety ropes with one end tied to the hook on both sides of the main safety rope. Two buffer tubes with an inner diameter larger than the diameter of the auxiliary safety rope are obliquely installed on the safety belt body. Limiting rings with an inner diameter equal to the diameter of the auxiliary safety rope are welded to the tops of the two buffer tubes. The end of the auxiliary safety rope far from the hook passes through the limiting ring and extends into the inner cavity of the buffer tube. A limiting slider with a diameter equal to the inner diameter of the buffer tube is tied to the end of the limiting ring far from the hook. A buffer spring is also sleeved on a section of the auxiliary safety rope located in the inner cavity of the buffer tube, and both ends of the buffer spring are abutted against the adjacent sides of the limiting slider and the limiting ring respectively.
[0007] By adopting the above technical solutions, when a user is working at a height, first fix the shoulder straps, waist belt and leg straps at their corresponding positions on the body, and then hang the hooks connected with the main safety rope and the secondary safety ropes on the building to protect oneself. If the user accidentally falls from a height, due to the shorter length of the main safety rope, the main safety rope is stressed first and pulls the user to prevent the user from falling directly to the ground. If the impact force is too large and causes the main safety rope to break, the main safety rope will first conduct preliminary buffering when breaking. At the same time, the two secondary safety ropes are stressed, and the limit sliders are pulled to slide along the inner cavity of the buffer tube, squeezing the buffer springs sleeved on the secondary safety ropes. After being squeezed by the limit sliders, the buffer springs contract to further buffer the impact force generated during the fall, preventing the impact force generated during the fall from causing the seat belt body to tighten sharply, which not only easily causes the seat belt to break due to the impact, but also the tightened seat belt may strangle the construction workers.
[0008] Optionally, the seat belt body includes a connecting piece with a double-layer structure. Two shoulder straps are symmetrically arranged on both sides of the connecting piece. The ends of the two shoulder straps are jointly connected with a waist belt in a ring structure. Two leg straps are sewn on both sides of the bottom of the waist belt.
[0009] By adopting the above technical solutions, the shoulder straps, waist belt and leg straps are provided to fix multiple parts of the construction worker's body, so as to disperse the impact force acting on the local part of the construction worker's body during the fall, effectively preventing the construction worker from being injured during the fall.
[0010] Optionally, the fixing member includes two fixing straps symmetrically arranged in the middle section of the front of the shoulder strap. One end of each of the two fixing straps is sewn to the shoulder strap, and a fixing buckle is tied to the end of the fixing strap away from the shoulder strap.
[0011] By adopting the above technical solutions, after the user puts the two shoulder straps on the bilateral shoulders, the two fixing straps can be pulled towards each other so that the male and female buckles of the fixing buckle are inserted into each other, thereby realizing the fixation of the shoulder straps.
[0012] Optionally, adjusting buckles are installed on both leg straps, and a hanging ring for hanging tools is sewn on the front of the waist belt.
[0013] By adopting the above technical solutions, the adjusting buckle is provided to adjust the length of the leg strap, and the hanging ring is sewn on the front of the waist belt, which is convenient for the construction worker to hang small construction tools such as wrenches and screwdrivers during the construction process.
[0014] Optionally, the length of the main safety rope is less than that of the secondary safety ropes.
[0015] By adopting the above technical solutions, the main safety rope is set shorter, so that when the user falls, the main safety rope is stressed first. When the impact force of the fall is too large and causes the main safety rope to break, the main safety rope can conduct preliminary buffering at the moment of breaking.
[0016] Optionally, the two buffer tubes are embedded between the two layers of connecting sheets, and the outer surfaces of the two buffer tubes are provided with a plurality of equally spaced annular grooves along the length direction of the buffer tubes.
[0017] By adopting the above technical solution, a plurality of equally spaced annular grooves are provided on the outer surface of the buffer tube to increase the friction between the outer surface of the buffer tube and the connecting sheet, thereby improving the stability of the buffer tube connection.
[0018] Optionally, the limiting slider has a spherical structure, and the diameter of the limiting slider is larger than the inner diameter of the limiting ring.
[0019] By adopting the above technical solution, the diameter of the limit slider is set to be larger than the inner diameter of the limit ring, which can minimize the limit slider from slipping out of the inner cavity of the limit ring, causing the secondary safety rope to separate from the safety belt body and failing to provide effective protection for the user.
[0020] In summary, the beneficial effects of this application are as follows:
[0021] The present application achieves double insurance by coordinating the main safety rope, the auxiliary safety rope, the buffer tube, the buffer spring and the limit slider. When the main safety rope breaks due to excessive impact, it can provide initial buffering at the moment of breaking. At the same time, the auxiliary safety rope is squeezed by the force and the buffer spring contracts to provide further buffering, so as to avoid the impact force generated by falling from causing the safety belt to be tightened sharply, which not only easily causes the safety belt to break due to impact, but also the tight safety belt may strangle the construction workers.

DETAILED DESCRIPTION
[0026] The following is combined with Figures 1 - 3 This application is described in further detail.
[0027] See alsoFigures 1 - 3 , a double - insurance safety belt for building construction, includes a safety belt body fixed to the human body through a fixing member, and a main safety rope 9 with one end fixedly connected to the safety belt body and the other end tied with a hook 10. When a user is constructing at a high place, the hook 10 can be hung on a high - strength building, so as to traction himself through the main safety rope 9 and try to avoid the user accidentally falling from a high place.
[0028] On both sides of the main safety rope 9, there are also two auxiliary safety ropes 11 with one end tied to the hook 10. The connection positions of the auxiliary safety ropes 11 and the hook 10 are different from those of the main safety rope 9 and the hook 10. The two auxiliary safety ropes 11 are provided to achieve double insurance. When the main safety rope 9 breaks due to impact, the auxiliary safety ropes 11 can continue to traction the user and prevent the user from falling off the building, greatly improving the safety protection performance of the overall safety belt.
[0029] Two buffer tubes 12 with an inner diameter larger than the diameter of the auxiliary safety rope 11 are inclinedly installed on the safety belt body. At the top of both buffer tubes 12, a limiting ring 13 with an inner diameter equal to the diameter of the auxiliary safety rope 11 is welded. One end of the auxiliary safety rope 11 away from the hook 10 passes through the limiting ring 13 and extends into the inner cavity of the buffer tube 12. A limiting slider 14 with a diameter equal to the inner diameter of the buffer tube 12 is tied to one end of the limiting ring 13 away from the hook 10, and the limiting slider 14 can slide in the inner cavity of the buffer tube 12.
[0030] A buffer spring 15 is also sleeved on a section of the auxiliary safety rope 11 located in the inner cavity of the buffer tube 12. Both ends of the buffer spring 15 are abutted against the adjacent sides of the limiting slider 14 and the limiting ring 13 respectively. When the impact force generated by falling off the building is small, the main safety rope 9 bears the force to protect the user. When the impact force is large and causes the main safety rope 9 to break, the main safety rope 9 first undergoes preliminary buffering through breaking. At the same time, the two auxiliary safety ropes 11 bear the force and traction the limiting slider 14 to slide in the inner cavity of the buffer tube 12, squeezing the buffer spring 15 sleeved on the auxiliary safety rope 11. After being squeezed by the limiting slider 14, the buffer spring 15 contracts to further buffer the impact force generated during the fall, preventing the problem that the impact force generated during the fall causes the safety belt body to tighten sharply and easily injure the staff.
[0031] Refer to Figure 1 , the safety belt body includes a connecting piece 1 with a double - layer structure. Two shoulder straps 2 are symmetrically arranged on both sides of the connecting piece 1. The ends of the two shoulder straps 2 are jointly connected to a waist belt 3 in a ring structure. Two leg straps 4 are sewn on both sides of the bottom of the waist belt 3. The shoulder straps 2, the waist belt 3 and the leg straps 4 are provided to fix multiple parts of the constructor's body, so as to disperse the impact force acting on the local part of the constructor's body during the fall and effectively prevent the constructor from being injured during the fall.
[0032] Refer to Figure 1The fixing part includes two fixing belts 5 symmetrically arranged in the middle section of the front side of the shoulder strap 2, one end of each of the two fixing belts 5 is sewn to the shoulder strap 2, and a fixing buckle 6 is fastened to the end of the fixing belt 5 away from the shoulder strap 2. When the user puts the two shoulder straps 2 on both shoulders, the two fixing belts 5 can be pulled toward each other, and the sub-mouth and the female buckle of the fixing buckle 6 are plugged into each other, thereby fixing the shoulder strap 2.
[0033] Reference Figure 2 The two leg straps 4 are both equipped with adjustment buckles 7, and a hanging ring 8 for hanging tools is sewn on the front of the waist belt 3. The adjustment buckle 7 is used to adjust the length of the leg strap 4, and the hanging ring 8 is sewn on the front of the waist belt 3, so that the construction workers can hang small construction tools such as wrenches and screwdrivers during the construction process.
[0034] Reference Figure 3 , the length of the main safety rope 9 is less than that of the auxiliary safety rope 11. The main safety rope 9 is set shorter so that when the user falls, the main safety rope 9 is stressed first. When the impact force of the fall is too large and causes the main safety rope 9 to break, the main safety rope 9 can be initially buffered at the moment of breaking.
[0035] Reference Figure 2 and Figure 3 The two buffer tubes 12 are embedded between the two layers of connecting plates 1, and the outer surfaces of the two buffer tubes 12 are provided with a plurality of equally spaced annular grooves 16 along the length direction of the buffer tubes 12. The plurality of equally spaced annular grooves 16 are provided on the outer surfaces of the buffer tubes 12 to increase the friction between the outer surfaces of the buffer tubes 12 and the connecting plates 1, thereby improving the stability of the connection of the buffer tubes 12.
[0036] Reference Figure 3 The limit slider 14 is spherical in structure, and the diameter of the limit slider 14 is larger than the inner diameter of the limit ring 13. Setting the diameter of the limit slider 14 to be larger than the inner diameter of the limit ring 13 can avoid the limit slider 14 from slipping out of the inner cavity of the limit ring 13 as much as possible, causing the secondary safety rope 11 to be separated from the safety belt body, and failing to provide effective protection for the user.
[0037] The implementation principle of this application is as follows: When a user is working at a high place, first fix the shoulder strap 2, waist strap 3 and leg strap 4 at their corresponding positions on the body, and then hang the hook 10 connected to the main safety rope 9 and the auxiliary safety rope 11 on the building to protect the user. If the user accidentally falls from a high place, due to the shorter length of the main safety rope 9, the main safety rope 9 is stressed first and pulls the user to prevent the user from falling directly to the ground. If the impact force is too large and causes the main safety rope 9 to break, the main safety rope 9 first undergoes preliminary buffering when it breaks. At the same time, the two auxiliary safety ropes 11 are stressed, and the limit slider 14 is pulled to slide along the inner cavity of the buffer tube 12, squeezing the buffer spring 15 sleeved on the auxiliary safety rope 11. After being squeezed by the limit slider 14, the buffer spring 15 contracts to further buffer the impact force generated during the fall, preventing the impact force generated during the fall from causing the seat belt body to tighten sharply. This not only easily causes the seat belt to break due to the impact, but also the tightened seat belt may injure the construction workers.
