[0002] Frequent high-altitude work involves heavy workload, high labor intensity, complex and changeable working environment, and high risk of falling. Accidents of falling from heights occur frequently, accounting for more than 40% of all types of accidents in power production and construction. Each power line department has formulated relevant measures to prevent high-altitude falls. However, in practice, workers often forget to hang or check due to bad working habits, resulting in the largest number of violations of this prohibition when climbing or moving at heights.

[0028] In order to make the above-mentioned purposes, features and advantages of the present invention more understandable, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] 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.

[0030] 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 is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1~Figure 3 , which is the first embodiment of the utility model, and this embodiment provides a fixing mechanism, including a clamping component 100 and a wear-resistant component 200. The clamping component 100 can be used to quickly fix the monitoring device to the safety belt hook, and the wear-resistant component 200 can be used to slow down the sliding speed of the hook when a person falls, thereby further ensuring the safety of the person.

[0033] Specifically, the clamping assembly 100 includes a pushing member 101 , a rotating member 102 and a receiving shell 103 , wherein the pushing member 101 and the rotating member 102 are respectively connected to two sides of the receiving shell 103 and can be further fixed by screws.

[0034] Furthermore, the wear-resistant component 200 includes an extrusion member 201 and a locking member 202 , wherein the locking member 202 is disposed on one side of the extrusion member 201 , and the extrusion member 201 is installed outside the accommodating shell 103 .

[0035] When in use, the operator installs the weak magnetic detection device on the safety belt hook, then holds the accommodating shell 103 and presses the pushing member 101 and the rotating member 102. At this time, the accommodating shell 103 unfolds and clamps the detection device and the hook to achieve initial fixation of the detection device to prevent parts from falling. After the installation is firm, the operator buckles the hook on the fixed object. When a fall occurs, the hook slides down, causing the fixed object to be stuck in the extrusion member 201 with a larger friction coefficient. Under the action of the locking member 202, it is not easy to disengage, so that the hook will not slide at will, further ensuring the safety of the operator.

[0036] In summary, by providing a pushing member, a rotating member and a accommodating shell, the monitoring component can be quickly connected to the seat belt hook, the installation efficiency is improved, and the problem of complicated installation of the monitoring module is solved. By providing an extrusion member and a locking member, when a person loses weight and falls, the fixed object in the hook will fall into the wear-resistant component and generate friction when the seat belt hook slides, thereby slowing down the sliding and falling speed, effectively protecting the safety of personnel.

[0037] Example 2

[0038] Reference Figure 1~Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment:

[0039] Specifically, the pushing member 101 includes a horizontal moving portion 101 a and a vertical moving portion 101 b , wherein one end of the horizontal moving portion 101 a movably contacts one end of the vertical moving portion 101 b .

[0040] Furthermore, the horizontal moving part 101a includes a button No. 101a-1, a compression spring No. 101a-2 and a bevel push rod No. 101a-3, wherein the two ends of the compression spring No. 101a-2 respectively resist the accommodating shell 103 and the button No. 101a-1, and the bevel push rod No. 101a-3 is integrally connected to one end of the button No. 101a-1 and cooperates with the vertical moving part 101b.

[0041] Preferably, when the first button 101a-1 is pressed in the X direction, the first compression spring 101a-2 is squeezed, and at the same time, the first bevel push rod 101a-3 squeezes and pushes the vertical moving part 101b to move vertically in the Y direction.

[0042] Furthermore, the vertical moving part 101b includes a second bevel push rod 101b-1 and a lifting sealing plate 101b-2, wherein the second bevel push rod 101b-1 is integrally connected to one side of the lifting sealing plate 101b-2 and cooperates with the first bevel push rod 101a-3.

[0043] Preferably, the contact surface between the first bevel push rod 101a-3 and the second bevel push rod 101b-1 is provided with a bevel surface, that is, when the first bevel push rod 101a-3 moves along the X direction, it will push the second bevel push rod 101b-1 to move vertically in the Y direction.

[0044] Furthermore, the rotating member 102 includes a No. 2 button 102a, a No. 2 compression spring 102b, a slide column 102c and a rotating sealing plate 102d, wherein the No. 2 button 102a and the No. 1 button 101a-1 are symmetrically arranged, and the two ends of the No. 2 compression spring 102b respectively abut against the No. 2 button 102a and the accommodating shell 103, and the slide column 102c is integrally connected to the side wall of the No. 1 button 101a-1 and contacts the rotating sealing plate 102d.

[0045] Furthermore, the rotating cover plate 102d also includes a rotating shaft 102d-1 and a sliding rail 102d-2, wherein the rotating shaft 102d-1 is vertically integrated with the side wall of the rotating cover plate 102d, and the sliding rail 102d-2 is spirally opened in the side wall of the rotating shaft 102d-1 in a groove shape and cooperates with one end of the sliding column 102c.

[0046] Preferably, when button No. 2 102a is pressed, compression spring No. 2 102b is squeezed, and slide column 102c moves synchronously in the opposite direction of X. At this time, the slide rail 102d-2 cooperating therewith rotates relatively, and the rotation angle is between 90° and 180°, and the rotating shaft 102d-1 drives the rotating sealing plate 102d to rotate, leaving space for the insertion of the monitoring device to be clamped and the seat belt hook.

[0047] When in use, the operator pinches the clamping assembly 100 with one hand, and the button No. 101a-1 and the button No. 2 102a move linearly relative to each other along the X direction. First, the button No. 101a-1 will drive the bevel push rod No. 101a-3 to move synchronously, and push the bevel push rod No. 2 101b-1 to move along the Y direction, and finally the lifting cover plate 101b-2 will be extended to adapt to the different thicknesses after the monitoring device and the safety belt hook are matched; when the button No. 2 102a is pressed, it drives the slide column 102c to move linearly synchronously, and makes the spiral slide rail 102d-2 embedded therein rotate relatively, and finally the rotating cover plate 102d is opened, so that the monitoring device can be inserted into the fixing mechanism after matching with the safety belt hook.

[0048] In summary, by providing a pushing member, a rotating member and a accommodating shell, the effect of quickly connecting the monitoring component to the safety belt hook is achieved, the installation efficiency is improved, and the problem of complicated installation of the monitoring module is solved.

[0049] Example 3

[0050] Reference Figure 1~Figure 4 , which is the third embodiment of the utility model, and this embodiment is based on the previous embodiment:

[0051] Specifically, the extrusion member 201 includes a roller 201a and a connecting shaft 201b, wherein both ends of the connecting shaft 201b are respectively connected to the side walls of the accommodating shell 103, and the roller 201a is sleeved on the connecting shaft 201b and can rotate.

[0052] Preferably, the accommodating shell 103 is provided at two locations, and correspondingly, the extrusion pieces 201 are also provided at two locations and are arranged opposite to each other, and the gap between the two locations is smaller than the diameter of the fixed object on which the safety belt hook is hung, that is, after the hook is buckled, the fixed object simultaneously fits the two rollers 201a.

[0053] Preferably, the surface of the roller 201a is provided with a rubber layer with relatively large friction force, which is used to increase the friction with the hanging fixed object when it is inserted, so as to slow down the sliding of the hook.

[0054] Furthermore, the locking member 202 includes a ratchet ring 202a and a pawl 202b, wherein the ratchet ring 202a is respectively connected to both sides of the roller 201a, and the pawl 202b is connected to the contact surface between the accommodating shell 103 and the connecting shaft 201b, that is, under the cooperation of the ratchet ring 202a and the pawl 202b, the roller 201a can only rotate in one direction.

[0055] During use, when an operator falls, gravity drives the safety belt hook to apply force downward. At this time, the relatively fixed hanging object will be squeezed and stuck in the two rollers 201a. Under the action of the locking member 202, the fixed hanging object is stuck and generates friction with the roller 201a, which effectively reduces the sliding speed of the hook, thereby further ensuring the safety of the operator.

[0056] Example 4

[0057] Reference Figure 1~Figure 4 , which is the fourth embodiment of the utility model, is based on the previous three embodiments, and the difference is that a weak magnetic detection device 300 is provided, which includes a Hall element housing 301, a circuit housing 302, a magnetic strip 303 and a seat belt hook 304.

[0058] Specifically, in this embodiment, the Hall element housing 301 is provided with two pieces, which are respectively arranged on both sides of the fixed end of the seat belt hook 304 and fixed thereto by a fixing mechanism. The circuit housing 302 is connected to one side of the two Hall element housings 301 and is used as a circuit integration of the monitoring device. The magnetic strip 303 is respectively arranged at the movable end and the fixed end of the seat belt hook 304 and is used to cooperate with the Hall element housing 301.

[0059] Furthermore, a Hall magnetic sensor 301 a is disposed inside the Hall element housing 301 , and the Hall magnetic sensor 301 a is in contact with the side wall of the seat belt hook 304 when clamped by the Hall element housing 301 .

[0060] When in use, the magnetic strip 303 forms a stable magnetic field around the seat belt hook 304. When the movable part of the seat belt hook 304 is opened or closed, it will affect the magnetic field distribution around the seat belt hook 304, and then affect the magnetic field strength nearby. At this time, the Hall magnetic sensor 301a determines the open and closed state of the seat belt hook 304 by detecting the magnetic field strength. When the seat belt hook 304 is hung with a fixed object (the fixed object is generally metal, that is, a magnetic conductive material), it will also affect the magnetic field distribution near the seat belt hook 304, and then affect the magnetic field strength. The Hall magnetic sensor 301a determines whether the seat belt hook 304 is hung with a fixed object by detecting the magnetic field strength. Finally, the Hall magnetic sensor 301a is connected to the STM32 to determine the magnitude of its magnetic field strength and the state of the seat belt hook 304. When the hook is opened or the fixed object is not hung during work, the staff is reminded through an audible and visual alarm.

[0061] In summary, by setting up a weak magnetic detection device, the opening and closing status of the seat belt hook can be fed back in time to remind the operator, thus solving the problem that the operator may forget to hang or check the seat belt hook.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
