[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0034] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0035] Example 1, reference Figure 1 , which is the first embodiment of the present invention, provides a smart safety belt with full protection. This device includes two safety ropes 100 connected to the straps, and a hanging unit 200 arranged at the end of the safety rope 100; the hanging unit 200 includes a hook 201 at the end of the safety rope 100, and a pull rope 202 arranged on the side of the hook 201.

[0036] The strap is worn on the staff, and two safety ropes 100 are installed on the strap. The hook 201 includes a dome 201a at the top, an extended edge 201b arranged at one end of the dome 201a, and a mounting arm 201c arranged at the other end of the dome 201a. The safety rope 100 is installed at the bottom of the mounting arm 201c, and the pull rope 202 is installed on the mounting arm 201c.

[0037] The dome 201a on the top of the hook 201 is used to buckle the fixed object for protection. When in use, the dome 201a is put into the fixed object, and the hanging relationship is maintained under the limit of the extended edge 201b and the mounting arm 201c. The mounting arm 201c is installed at an angle, and the bottom of the mounting arm 201c is located directly below the center of gravity of the entire hanging unit 200. When the safety rope 100 is installed under the mounting arm 201c, the safety rope 100 is in line with the center of gravity of the entire hanging unit 200 and is vertically downward.

[0038] The pull rope 202 is installed in the middle of the installation arm 201c, and the force point of the pull rope 202 on the installation arm 201c deviates from the center of gravity of the hanging unit 200 and is opposite to the extended edge 201b. When the pull rope 202 is pulled, the center of gravity of the hanging unit 200 will be shifted, causing the installation arm 201c to rotate around the contact point between the dome 201a and the fixed object, so that the center of gravity of the hanging unit 200 coincides with the pull rope 202. At this time, the gap between the installation arm 201c and the extended edge 201b is relatively horizontal with the fixed object. When the pull rope 202 is shaken, the hook 201 can be detached from the fixed object, thereby realizing the disassembly of the hanging unit 200.

[0039] Furthermore, there is an angle α between the extended edge 201b and the center of gravity line of the hanging unit 200, wherein 45°≤α≤75°, and the extended edge 201b is inclined with respect to the vertical direction. When the pull rope 202 is pulled, the center of gravity of the hanging unit 200 changes. At the same time, the gap between the mounting arm 201c and the extended edge 201b is in a relatively horizontal state with respect to the fixed object. At this time, there is an angle α between the extended edge 201b and the horizontal state, and under the pulling of the pull rope 202, the extended edge 201b and the fixed object will slide relative to each other, so that the fixed object automatically detaches from the gap between the mounting arm 201c and the extended edge 201b, thereby realizing the disassembly of the hanging unit 200.

[0040] During use, when the staff is working at height, the two hanging units 200 are hung on the fixed objects to achieve double insurance. When the staff moves, the hanging units 200 can be transferred from one fixed object to another fixed object in turn, avoiding the existence of empty periods and increasing safety.

[0041] Furthermore, when the worker is performing a crawling operation and moves away from the hanging unit 200 and cannot remove the hanging unit 200 by hand, the pull rope 202 can be pulled so that the gap between the mounting arm 201c and the extended edge 201b is relatively level with the fixed object and can automatically detach from the fixed object, and then the pull rope 202 can be hung at a position that the worker can touch and crawl again, so as to protect the worker while crawling.

[0042] Example 2, reference Figure 2 , which is the second embodiment of the present invention, which is different from the first embodiment in that: the bottom hinge of the mounting arm 201c is connected with an anti-slip component 203, and the end of the anti-slip component 203 is located between the extended edge 201b and the mounting arm 201c;

[0043] The anti-slip component 203 abuts against the end of the extended edge 201b; the anti-slip component 203 abuts against the extended edge 201b to close the gap between the mounting arm 201c and the extended edge 201b, and when the fixed object is hung on the dome 201a, it can effectively prevent the fixed object from detaching from the hook 201.

[0044] The pull rope 202 passes through the stress point of the installation arm 201c and is connected to the anti-slip assembly 203, wherein a limiting ring 201d is provided on the installation arm 201c, and the pull rope 202 passes through the limiting ring 201d and is connected to the anti-slip assembly 203; the limiting ring 201d is located at the stress point of the installation arm 201c.

[0045] Furthermore, the anti-drop assembly 203 includes an anti-drop rod 203a plugged into the mounting arm 201c, an accommodation space for clamping is provided inside the anti-drop rod 203a, and the anti-drop rod 203a is rotatably connected to the mounting arm 201c through a mounting shaft 203b; and a spring 203c provided between the anti-drop rod 203a and the mounting arm 201c;

[0046] The anti-slip rod 203a is L-shaped, and a groove 203d is provided at the end of the long rod of the anti-slip rod 203a, and the extended edge 201b is plugged into the groove 203d; under the elastic force of the spring 203c, the long rod end of the anti-slip rod 203a is against the extended edge 201b, so that the gap between the mounting arm 201c and the extended edge 201b is closed.

[0047] When hook 201 is hooked to a fixed object, it is only necessary to press the anti-slip rod 203a against the fixed object so that the fixed object squeezes the anti-slip rod 203a and separates it from the extended edge 201b. At this time, the fixed object can enter the interior of the hook 201 and contact the dome 201a under the action of gravity to achieve hooking. At the same time, under the elastic force of the spring 203c of the anti-slip rod 203a, the long rod end of the anti-slip rod 203a presses against the extended edge 201b to close the gap between the mounting arm 201c and the extended edge 201b, which can effectively prevent the fixed object from detaching from the hook 201.

[0048] Further, the short rod end of the anti-drop rod 203a is connected to the pull rope 202, and a rotation groove 201e is provided on the mounting arm 201c. A limiting shaft 203e is provided at the short rod end of the anti-drop rod 203a, and the limiting shaft 203e is slidably inserted in the rotation groove 201e;

[0049] The end of the pull rope 202 is connected to the limit shaft 203e, and the pull rope 202 passes through the bottom of the rotating groove 201e and then passes through the limit ring 201d again; when the pull rope 202 is pulled, the anti-slip rod 203a can rotate and separate from the extended edge 201b, reopening the gap between the mounting arm 201c and the extended edge 201b.

[0050] The elastic force of the spring 203c is relatively small. When the pull rope 202 is pulled, the anti-slip rod 203a will be controlled to rotate first to open the gap between the installation arm 201c and the extended edge 201b. When the anti-slip rod 203a moves to form an end, the pull rope 202 will exert force on the limiting ring 201d to make the installation arm 201c rotate around the contact part of the dome 201a until it is detached from the fixed object to realize the separation of the hanging unit 200.

[0051] Or in order to increase the pressure between the anti-drop rod 203a and the extended edge 201b, improve the ability of the anti-drop rod 203a to be opened by mistake, and increase the elastic force of the spring 203c, it is necessary to provide an arc-shaped limit rod 203f at the end of the long rod of the anti-drop rod 203a, and the limit rod 203f is rotatably inserted in the installation arm 201c; the limit rod 203f, the anti-drop rod 203a and the installation arm 201c form a blocking space. When the pull rope 202 is pulled, the anti-drop rod 203a and the installation arm 201c may rotate at the same time, or the installation arm 201c may rotate first. The existence of the blocking space can effectively avoid that when the installation arm 201c rotates first, it is ensured that the fixed object will not move into the space between the anti-drop rod 203a and the installation arm 201c, and ensure that when the anti-drop rod 203a is opened, the fixed object can be separated from the extended edge 201b, thereby realizing the disassembly of the hanging unit 200.

[0052] The remaining structures are the same as those of Example 1.

[0053] During use, when the worker is performing a climbing or ascending operation, when the worker moves away from the hanging unit 200 and cannot remove the hanging unit 200 by hand, the pull rope 202 can be pulled to make the gap between the mounting arm 201c and the extended edge 201b relatively level with the fixed object, and the anti-detachment rod 203a can be automatically detached from the fixed object after being opened, and then it can be hung at a position that the worker can touch and crawl again, so as to protect the worker while crawling.

[0054] Example 3, reference Figure 3 and Figure 4 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: a sliding rod 204 is provided at the bottom of the mounting arm 201c, and a through groove 204a is provided in the sliding rod 204; the end of the safety rope 100 is slidably connected to the sliding rod 204, and the pull rope 202 passes through the through groove 204a.

[0055] A limiting through hole 101 is provided on the side of the safety rope 100. The pull rope 202 passes through the through groove 204a and then passes through the limiting through hole 101. A control pull ring is installed at the end of the pull rope 202 that exceeds the limiting through hole 101. The pull rope 202 can be controlled by pulling the pull ring.

[0056] Furthermore, the sliding rod 204 includes a connecting side 204b, a center of gravity side 204c and a sliding side 204d; the connecting side 204b is fixed to the mounting arm 201c, the center of gravity side 204c is located directly below the center of gravity of the hanging unit 200, and the sliding side 204d is on the same side as the force point of the mounting arm 201c.

[0057] The pull rope 202 slides through the limiting perforation 101 and can be bound to the safety rope 100 to prevent the pull rope 202 from flying around and also prevent the pull rope 202 from being accidentally pulled. The safety rope 100 can slide on the sliding rod 204 under the action of gravity. When the pull rope 202 is pulled to disassemble the hanging unit 200, the pull rope 202 will drive the safety rope 100 to slide to the sliding side 204d and be located below the limiting ring 201d, so that the pull rope 202 will not be excessively bent, thereby reducing the loss of tension.

[0058] The remaining structure is the same as that of Example 2.

[0059] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
