Description

Technical Field

[0001] The utility model relates to the technical field of safety belts, in particular to a new type of buffer safety belt for construction. Background Art

[0002] As a human safety protection device during construction, seat belts are generally composed of buckles, belt heads, shoulder straps, waist belts, pretensioners, tension limiters, seat belt indicator lights and fixed accessories.

[0003] First of all, the safety belts in the prior art generally adopt a straight-pull type, and the upper safety rope is directly hung at a reliable connection point of the building through a clip to prevent people from falling when working at height. Generally, the protective measures of the safety belt are directly transmitted through the upper protection rope during use. Once a fall accident occurs, due to the influence of the human body's own gravity, the safety belt will suddenly be stretched straight. When a falling accident occurs, due to the influence of the falling object's own gravity, the user will be pulled in the opposite direction by the safety belt, and the safety belt will cause different degrees of strain on the falling object. Utility Model Content

[0026] The embodiment of the present application provides a new type of buffer safety belt for construction construction, which effectively solves the problem that the protective measures of general safety belts are directly transmitted through the upper protection rope during use. Once a falling accident occurs, the safety belt will suddenly be stretched straight due to the influence of the human body's own gravity. When a falling accident occurs, the user will be pulled in the opposite direction by the safety belt due to the influence of the falling object's own gravity. The safety belt will cause different degrees of strain on the falling object. When the user accidentally falls, the waist belt and the port will fall downward, which will stretch the suspension belt and put the suspension belt in a stretched state. At the same time, one end of the suspension belt first stretches the buffer spring. Under the action of gravity, the bottom end of the buffer spring is stretched downward to straighten the buffer spring. During the stretching of the buffer spring, the suspension belt simultaneously pulls one end of the buffer spring to gradually straighten the safety rope during the stretching of the buffer spring. The suspension belt uses the buffer spring to buffer the force of the suspension belt due to gravity during the falling process, thereby reducing the falling force and avoiding strain on the user.

[0027] Example

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that the protective measures of the general safety belt directly transmit force through the upper protection rope during use. Once a fall accident occurs, the safety belt will suddenly be stretched straight due to the influence of the human body's own gravity. When a fall accident occurs, due to the influence of the falling object's own gravity, the user will be pulled in the opposite direction by the safety belt, and the safety belt will cause different degrees of strain on the falling object. The overall idea is as follows:

[0029] In view of the problems existing in the prior art, the utility model provides a new type of buffer safety belt for construction, which includes a suspension belt 14, one end of which is fixedly installed with a safety rope 17, two pull rings 21 are fixedly installed on the side end of the suspension belt 14, and the side ends of the two pull rings 21 are movably installed with the same buffer spring 19, and at least two fixed rivets 18 are installed through the surface of the suspension belt 14. During the unloading and falling process of the suspension belt 14 through the buffer spring 19, gravity buffers the tensile strength of the suspension belt 14 to a certain extent, thereby reducing the falling strength;

[0030] The safety rope 17 is bent on one side of the suspension belt 14, and the two ends of the safety rope 17 are connected to the suspension belt 14 respectively. The safety rope 17 is fixedly connected to the suspension belt 14 by fixing the rivet 18. At the same time, the end of the pull ring 21 is fixedly connected to the suspension belt 14. The two ends of the buffer spring 19 must be reliably connected to the pull ring 21, that is, the two ends of the buffer spring 19 are inserted into the pull ring 21 and fixedly connected by welding. The buffer spring 19 and the safety rope 17 resist the falling tension. The buffer spring 19 is connected to the suspension belt 14 at the top and bottom, and is tightly connected by welding to ensure that there is no breakage between the buffer spring 19 and the pull ring 21.

[0031] A connecting plate 12 is fixedly installed at the end of the suspension belt 14, and the surface of the connecting plate 12 is fixed by a fixing rivet 18. At least two shoulder straps 13 are fixedly installed at the two side ends of the connecting plate 12, and a port 11 is fixedly installed at the bottom end of each shoulder strap 13. Multiple shoulder straps 13 are installed equidistantly on one side of the connecting plate 12, and the same waist belt 1 is fixedly installed at the end of each shoulder strap 13. The end of the shoulder strap 13 is fixedly connected to the waist belt 1 by a fixing rivet 18. A connecting ring 15 is fixedly installed at the top of the suspension belt 14, and a safety hook 16 is movably installed at the top of the connecting ring 15. After the end of the connecting ring 15 is in contact with the suspension belt 14, it is fixedly connected by a fixing rivet 18.

[0032] Working principle:

[0033] The first step is to put the processed belt 1 on the user's neck during use, and then separate the multiple ports 11 from each other to fit the user's chest and back respectively, and one side of the connecting plate 12 is in close contact with the user's back. Take the mobile safety hook 16, find the building concrete components, steel pipes, expansion bolts, wire ropes, etc. that can be hung, and press one end of the safety hook 16 to allow the spring block inside the safety hook 16 to expand and contract, open an opening on one side of the safety hook 16, and put the safety hook 16 into the hanging point. At the same time, by pulling the suspension belt 14, a pulling force is applied to the suspension belt 14 to detect whether one end of the safety hook 16 is tightly connected to the hanging point.

[0034] In the second step, when the user accidentally falls, the waist belt 1 and the port 11 fall downward, which will stretch the suspension belt 14 and make the suspension belt 14 in a straight state. At the same time, one end of the suspension belt 14 first stretches the buffer spring 19. Under the action of gravity, the bottom end of the buffer spring 19 is forced to stretch downward to make the buffer spring 19 straight. During the stretching of the buffer spring 19, the suspension belt 14 simultaneously pulls one end of the buffer spring 19 to make the safety rope 17 gradually straighten during the stretching of the buffer spring 19, and pulls the suspension belt 14 in the opposite direction. The safety rope 17 resists the upper tension, and the buffer spring 19 and the safety rope 17 resist the falling tension. The buffer spring 19 is connected to the suspension belt 14 above and below, and is tightly connected by welding to ensure that there is no breakage between the buffer spring 19 and the pull ring 21, which can better ensure the safety and reliability of the safety belt. During the unloading and falling process of the suspension belt 14 through the buffer spring 19, gravity buffers the force of the suspension belt 14 to a certain extent, reduces the falling force, and avoids straining the user.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
