The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] Figure 1 Schematic diagram of the structure of a safety belt 10 provided according to an embodiment of the utility model. Figure 2 FIG. 1 is a front view of a safety belt 10 provided according to an embodiment of the utility model. Figure 3 is a schematic diagram of the structure of a detection device 20 provided according to an embodiment of the utility model, Figure 4 It is a schematic diagram of the structure of the controller 21 provided according to an embodiment of the utility model.

[0044] Reference below Figure 1-Figure 4 Description: According to an embodiment of the utility model, a seat belt 10 includes a seat belt body 11, a hook 12, a safety rope 13 and a detection device 20. The seat belt body 11 is connected to the hook 12 through the safety rope 13; the detection device 20 is used to respectively detect a first air pressure value at the seat belt body 11 and a second air pressure value at the hook 12, and obtain the air pressure difference between the seat belt body 11 and the hook 12 according to the first air pressure value and the second air pressure value, and compare the obtained air pressure difference with a preset air pressure difference threshold value, and trigger a warning signal according to the comparison result.

[0045] Since the safety rope 13 of the safety belt 10 has a certain length, during use, if the hook 12 is lower than the operator and is buckled in a fixed position, if the operator falls accidentally, he will fall a distance equal to the length of the safety rope 13 and then be caught by the safety rope 13. The operator being caught by the safety rope 13 suddenly will cause an impact on the operator. The lower the hook 12 is hung, the longer the falling distance is, and the greater the impact of the safety rope 13 on the operator is. In serious cases, it will cause fatal injuries to the operator. Therefore, it is necessary to follow the principle of hanging high and using low.

[0046] Therefore, when the safety belt 10 is in use, the position where the hook 12 is bolted should always be higher than the position where the operator is when working at height, so as to meet the principle of "hanging high and using low" for the use of the safety belt 10, so as to better provide safety protection for the operator. However, in actual operation, the operator often ignores the synchronous adjustment of the bolting position of the hook 12 when changing the working position, which will cause the risk of safety accidents to the operator to surge. In this embodiment, a detection device 20 can be set on the safety belt 10, and the detection device 20 can detect the relative height difference between the hook 12 and the main body of the safety belt 10 worn by the operator in real time, and when the working position of the operator is higher than the bolting position of the hook 12, the detection device 20 can promptly remind the operator to change the bolting position of the hook 12, so as to effectively avoid safety accidents.

[0047] Please continue to see Figure 1 and 2 As shown, according to another embodiment of the utility model, the safety belt body 11 includes a first fixing belt 111, a second fixing belt 112 and a third fixing belt 113.

[0048] Specifically, the safety belt body 11 can be fixed on the waist, back, legs, shoulders, etc. of the operator by wearing it. The hook 12 can be fixedly connected to the safety belt body 11, and the hook 12 can be bolted to a relatively firm component or object.

[0050] Furthermore, the head end of the second fixing belt 112 is fixedly connected to the first connecting portion of the annular body by sewing or the like, and the tail end thereof is fixedly connected to the third connecting portion of the annular body by sewing or the like; the head end of the third fixing belt is fixedly connected to the fourth connecting portion of the annular body by sewing or the like, and the tail end thereof is fixedly connected to the second connecting portion of the annular body by sewing or the like, which can make the safety belt 10 stronger and more durable.

[0051] Specifically, the first connection part, the second connection part, the third connection part and the fourth connection part all include a plurality of sub-connections, the head end of the second fixing belt is divided into connection ends with the same number of strands as the sub-connections of the first connection part, and is fixedly connected to the sub-connections of the first connection part in a one-to-one correspondence, and the tail end thereof is divided into connection ends with the same number of strands as the sub-connections of the third connection part, and is fixedly connected to the sub-connections of the third connection part in a one-to-one correspondence; the head end of the third fixing belt is divided into connection ends with the same number of strands as the sub-connections of the fourth connection part, and is fixedly connected to the sub-connections of the fourth connection part in a one-to-one correspondence, and the tail end thereof is divided into connection ends with the same number of strands as the sub-connections of the second connection part, and is fixedly connected to the sub-connections of the second connection part in a one-to-one correspondence.

[0056] Specifically, the first detection member 22 and the second detection member 23 can adopt air pressure height sensors to detect the air pressure at different height positions, and calculate the air pressure difference between the two relative height positions through the controller 21. The height difference between the two relative height positions can be calculated through the air pressure difference. With such a setting, the different height values ​​of the two relative positions can be accurately judged, and this principle can be applied between the seat belt body 11 and the hook 12 to meet the use principle of "high hanging and low use" of the seat belt 10.

[0062] Specifically, the first detection member 22 is fixed on the controller 21 , and the controller 21 is fixedly mounted on the seat belt body 11 . Such an arrangement can effectively simplify the overall structure of the seat belt 10 and significantly reduce the weight of the seat belt 10 .

[0063] Please continue to see Figure 1 and 2 As shown, according to another embodiment of the present invention, the first detection member 22 is detachably connected to the first fixing belt 111 , the second fixing belt 112 or the third fixing belt 113 through the controller 21 .

[0064] Specifically, the first detection component 22 is welded to the controller 21, and the controller 21 is bonded to the first fixing belt 111, the second fixing belt 112 or the third fixing belt 113. Such a configuration can facilitate the operator to adjust the position of the first detection component 22 and the controller 21 according to the actual working environment to avoid mutual interference with the working process; at the same time, it can further facilitate the replacement and maintenance of the first detection component 22 and the controller 21.

[0065] Alternatively, the first detection member 22 is connected to the controller 21 by bolts, and the controller 21 is bonded to the first fixing belt 111 , the second fixing belt 112 , or the third fixing belt 113 .

[0066] Please continue to see Figure 1 and 2 As shown, according to another embodiment of the present invention, the first detection member 22 is slidably connected to the first fixing belt 111 , the second fixing belt 112 or the third fixing belt 113 through the controller 21 .

[0067] Specifically, the first detection member 22 is welded to the controller 21, and the controller 21 is slidably connected to the first fixing belt 111, the second fixing belt 112 or the third fixing belt 113 by setting a sliding sleeve, and the sliding sleeve is adhesively connected to the corresponding fixing belt (the first fixing belt 111, the second fixing belt 112 or the third fixing belt 113). Such a setting ensures that the first detection member 22 and the controller 21 can facilitate the operator to adjust the position of the first detection member 22 and the controller 21 according to the actual working environment, and at the same time, it can also ensure that the first detection member 22 and the controller 21 are fixed more securely to avoid accidental falling.

[0068] Alternatively, the first detection member 22 is connected to the controller 21 by bolts, and the controller 21 is slidably connected to the first fixing belt 111, the second fixing belt 112 or the third fixing belt 113 by setting a sliding sleeve, and the sliding sleeve is adhesively connected to the corresponding fixing belt (i.e., the first fixing belt 111, the second fixing belt 112 or the third fixing belt 113).

At the same time, the communication module 212 can be connected to the processing module 213 by wired connection or wireless connection, so that the communication module 212 can pass the received air pressure value to the processing module 213. After receiving the air pressure value, the processing module 213 can perform a specific calculation to obtain the air pressure difference, and compare it with the preset air pressure difference threshold, and trigger an early warning signal according to the comparison result. And determine whether the use of the safety belt 10 meets the use rule of "high hanging and low use", and the processing module 213 can send a warning signal to the operator in a timely manner.

According to the set high hanging and low use judgment condition, the pressure difference threshold can be preset to zero, and the processing module 213 obtains the pressure difference between the first air pressure value and the second air pressure value. When the pressure difference calculated by the processing module 213 is greater than zero, it is determined that the first air pressure value is greater than the second air pressure value, the height position of the safety belt body 11 is lower than the height position of the hook 12, and the processing module 213 does not trigger the warning signal. When the pressure difference calculated by the processing module 213 is less than or equal to zero, it is determined that the first air pressure value is less than or equal to the second air pressure value, the height position of the safety belt body 11 is higher than or equal to the height position of the hook 12, and the processing module 213 triggers the warning signal.
