[0035] 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.

[0036] 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.

[0037] 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.

[0038] Example 1

[0039] Reference Figure 1 to Figure 4 , is the first embodiment of the present invention, which provides a safety belt hanging device for edge work, including a line-retracting and -releasing unit 100, including a box body 101, a fixing ring 102 arranged inside the box body 101, a rotatable turntable 103 arranged inside the fixing ring 102, a reset member 104 wound around the outer side of the rotating shaft of the turntable 103, a connecting rope 105 connected to the end of the reset member 104, and a cover plate 106 arranged opposite to the box body 101.

[0040] In this embodiment, the box body 101 is a hollow shell structure, which provides a space for movement and installation of other components to ensure that the various components can be combined and connected; the outer wall of the box body 101 is also connected to a fixing ring, which can ensure that the retraction unit is connected to the safety belt.

[0041] Specifically, the fixing ring 102 is a cylindrical structure with an open top, and the box body 101 and the fixing ring 102 are connected and fixed; the fixing method can be achieved by clamping, welding or bolting.

[0042] Preferably, the box body 101 and the fixing ring 102 are fixed by bolt connection, which is more secure than the clamping thread connection and saves effort during disassembly. The welding method increases the manufacturing cost of the equipment and requires replacement of a whole set of parts during maintenance of the device, which may cause waste of resources to a certain extent.

[0043] Furthermore, the interior of the fixed ring 102 mainly provides a relatively independent space for the resetting member 104 and the winding of the connecting rope 105; during the process of releasing the resetting member 104, the movement of the connecting rope 105 can be limited by the contact between the connecting rope 105 and the inner wall of the fixed ring 102, ensuring that the connecting rope 105 can be stably extended and retracted multiple times.

[0044] Furthermore, the turntable 103 is located inside the fixed ring 102 and rotates; a reset member is provided on the outer side of the rotating shaft of the turntable 103 to drive the turntable 103 to rotate during the compression or expansion process; thereby, the rotation of the turntable 103 can drive the connecting rope 105 to be wound around its outer side.

[0045] It should be noted that the main function of the reset member 104 is to provide a rewinding torque after the connecting rope 105 is stretched, to ensure that the connecting rope 105 can be automatically retracted; the reset member 104 can be a torsion spring, a volute spring or a tape spring; the reset member 104 stores energy during the stretching process of the connecting rope 105, and then releases the energy during the contraction process of the connecting rope 105.

[0046] Preferably, the reset member 104 is a tape spring, which occupies a smaller space than a torsion spring and generates a greater torque under the same volume; compared with a volute spring, the tape spring has a lower manufacturing cost and can effectively control the manufacturing cost of the equipment.

[0047] Furthermore, the outer wall of the box body 101 is provided with a positioning assembly 200; the positioning assembly 200 can fix the extended length of the connecting rope 105; the connecting rope 105 can be wound around the outside of the fixing device to provide a stable hanging point.

[0048] In this embodiment, in order to further ensure that the extended length of the connecting rope 105 can be fixed; the extended length of the connecting rope 105 can be limited by setting a positioning component 200; the positioning component can be a metal sheet structure, and the connecting rope 105 is fixed inside the box body 101 by friction; it can also be a method of clamping and fixing the connecting rope 105 by two groups of clamping plates, and then pressing the connecting rope 105 against the rope outlet by spiral feeding.

[0049] Preferably, the positioning assembly 200 uses a spiral feeding method to press the connecting rope 105 to achieve the fixation of the connecting rope 105; compared with clamping the connecting rope 105 through the friction force of the metal sheet, the connecting rope 105 is subjected to greater pressure during actual use, and a single metal sheet cannot fix the connecting rope 105 well; and the method of clamping with a clamping plate cannot fully realize its function inside a smaller device; therefore, the use of a spiral feeding method can ensure that the connecting rope 105 is fixed while meeting the small size of the equipment, further meeting the assembly relationship.

[0050] Furthermore, after fixing the extended distance of the connecting rope 105, the operator can wrap the end of the connecting rope 105 around the outside of the cylinder and then fix it with a knot. The operator can also use the method of connecting the end of the connecting rope 105 with a buckle. After wrapping the connecting rope 105 around for one circle, the connecting buckle is overlapped on the connecting rope 105 on the other side, thereby forming a stable circle, providing a stable hanging point for the operator.

[0051] In summary, the present invention adopts a high-strength self-locking rope loop with adjustable length as a temporary hanging point, which is suitable for steel pipe poles with large diameter and no ladder, trees and fixed objects at a long distance; it can also free the hands of supervisors, improve work efficiency, and prevent operators from taking risks and violating regulations, eliminating the serious safety hazards of working on the edge without a safety belt hanging point.

[0052] Example 2

[0053] Reference Figure 1 to Figure 5, which is the second embodiment of the present invention, and is different from the first embodiment in that: it also includes: the fixing ring 102 and the box body 101 are detachably connected by bolts, and the turntable 103 is coaxially arranged with the fixing ring 102; the turntable 103 can be located inside the fixing ring 102 and rotate, one end of the reset member 104 is fixed to the inner side of the rotating shaft of the turntable 103, and the other end thereof is connected to the connecting rope 105.

[0054] It should be noted that the outer wall of the fixing ring 102 is provided with multiple sets of bolt fixing holes, and the bolts can be passed through the fixing holes to connect and fix the fixing ring 102 and the box body 101; the fixing ring 102 can be more firmly installed on the inner side of the box body 101 through multiple sets of bolts, thereby ensuring the stability of the installation.

[0055] Furthermore, a raised portion is provided at the bottom of the turntable 103 and overlaps with a recessed portion on the inner side of the fixed ring 102, thereby ensuring that the turntable 103 can rotate along the inside of the fixed ring 102. The rotation of the turntable 103 can drive the reset member 104 provided on its outer side to reel in, thereby ensuring that the connecting rope 105 is evenly and smoothly reeled in on the outer side of the turntable 103.

[0056] Specifically, the other end of the reset member 104 can pass through the rotating shaft of the turntable 103 and then be wrapped around the outside of the turntable 103, so that one end of the turntable reset member 104 is fixedly connected to the turntable 103. The end of the reset member 104 can also be fixedly connected to the turntable 103 by bolt connection.

[0057] The other end of the reset member 104 is connected to the connecting rope 105, which can be fixedly connected by a snap-fitting method or pressed tightly between the reset member 104 and the connecting rope 105 by the cooperation between a bolt and a nut; thereby ensuring that the reset member 104 and the connecting rope 105 can be quickly assembled during the assembly process; so that the extension and retraction of the connecting rope 105 can drive the reset member 104 to contract or expand.

[0058] Furthermore, the connection rope 105 is wound around the outside of the reset member 104; the extension and retraction of the connection rope 105 can drive the reset member 104 to retract and release energy.

[0059] It should be noted that the reset member 104 is preferably a tape measure spring structure. During use, the connecting rope 105 can be wrapped around the outside of the reset member 104, and the connecting rope 105 and the reset member 104 are combined into a disc structure; and the reset member 104 can change its state as the connecting rope 105 expands and contracts during the process of retracting and releasing potential energy.

[0060] Furthermore, the box body 101 includes a rope outlet 101a opened on its side wall, and a limiting rod 101b arranged inside the rope outlet 101a; the surface of the connecting rope 105 is closely attached to the side wall of the limiting rod 101b.

[0061] Preferably, the rope outlet 101a is opened on the side wall of the box body 101, and the rope outlet 101a passes through the side wall of the box body 101 and extends to the outside thereof; the connecting rope 105 wound inside the fixing ring 102 can pass through the side wall of the fixing ring 102 and extend to the inside of the rope outlet 101a; the end of the connecting rope 105 passes through the rope outlet 101a and extends to the outside of the box body 101, so that the connecting rope 105 can be stretched to a certain length; and the limiting rod 101b is arranged inside the rope outlet 101a; the connecting rope 105 will pass above the limiting rod 101b when passing through the rope outlet 101a; so that the connecting rope 105 forms a certain bend on both sides of the limiting rod 10b; the connecting rope 105 can be limited to a certain extent.

[0062] In this embodiment, the positioning assembly 200 includes a screw sleeve 201 arranged at a position relative to the rope outlet 101a, a push rod 202 arranged on the inner side of the screw sleeve 201, a pressure plate 203 arranged at the bottom of the push rod 202, and a knob 204 arranged at the end of the screw sleeve 201; the pressure plate 203 can press the connecting rope 105 tightly inside the rope outlet 101a.

[0063] It should be noted that the screw sleeve 201 and the box body 101 are fixed by bolts; and the interior of the screw sleeve 201 is provided with an external thread structure that is compatible with the outer wall of the push rod 202, so that when the push rod 202 is rotated, the push rod 202 is spirally fed along the axial direction of the screw sleeve 201; at the same time, the end of the push rod 202 is connected to a pressure plate 203; the push rod 202 and the pressure plate 203 are cast in an integral molding manner, and the structure of the push rod 202 and the pressure plate 203 is simple, and the manufacturing of parts can be completed relatively simply by casting.

[0064] Furthermore, the pressing plate 203 is provided with an array of protrusions at the extrusion portion near the bottom; the protrusions can increase the friction force of the contact surface between the pressing plate 203 and the connecting rope 105, thereby ensuring that the pressing plate 203 presses the connecting rope 105 more firmly.

[0065] Specifically, the knob 204 is arranged on the outer wall of the box body 101, and then rotating the knob 204 can drive the pressure plate 203 to move along the axial direction of the screw sleeve 201; when the pressure plate 203 moves in the direction close to the connecting rope 105, the end of the pressure plate 203 can contact the connecting rope 105 and press the connecting rope 105 against the inner wall of the rope outlet 101a; thereby, the connecting rope 105 can be fixed; and then the extended length of the connecting rope 105 can be controlled; the fixed length can ensure that a stable hanging point is provided for the staff, thereby ensuring the safety of the staff's work.

[0066] Furthermore, the outer thread of the push rod 202 connecting the screw sleeve 201 and the box body 101 is matched with the inner thread of the screw sleeve 201 , and the push rod 202 can push the pressing plate 203 to approach the connecting rope 105 by spiral feeding.

[0067] It should be noted that the outer surface of the screw sleeve 201 coincides with the outer wall of the box body 101, and the end of the screw sleeve 201 protrudes from the inner side of the inner wall of the box body 101; the screw sleeve 201 and the box body 101 are fixedly connected by bolts. It should be noted that the push rod 202 is located inside the screw sleeve 201 and rotates, and the push rod 202 rotates while the bolt is fed in.

[0068] Furthermore, the push rod 202 penetrates the screw sleeve 201 and extends to the outside thereof; the knob 204 includes a rotating rod 204 a; and the end of the rotating rod 204 a extends to the inside of the screw sleeve 201 .

[0069] It should be noted that the end of the push rod 202 is connected to one side of the pressure plate 203, passes through the screw sleeve 201 and extends to its outside; the end of the rotating rod 204a passes through the inner side of the screw sleeve 201; the rotating rod 204a that passes through the inside of the screw sleeve 201 can better cooperate with the push rod 202, thereby ensuring that the knob 204 is located outside the box body 101 and the rotation can drive the push rod 202 to rotate; the push rod 202 rotates and spirally feeds to drive the pressure plate 203 to move.

[0070] Furthermore, the push rod 202 includes a groove 202a opened at a central position, and the groove 202a is adapted to the rotating rod 204a; the rotating rod 204a is movably connected to the groove 202a.

[0071] It should be noted that the groove 202a is a non-circular structure, and the rotating rod 204a is adapted to the groove 202a; the rotating rod 204a can drive the push rod 202 to rotate during rotation; and the groove 202a is located in the center of the push rod 202, thereby ensuring that the push rod 202 rotates along the axis of the screw sleeve 201.

[0072] Furthermore, the end of the knob 204 contacts the side wall of the box body 101 ; a limit block 107 is provided on the side wall of the box body 101 , and the knob 204 is limited in its axial movement by the limit block 107 .

[0073] Preferably, the limit block 107 and the box body 101 are welded and fixed or connected and fixed with bolts; and the limit block 107 is an inverted L-shaped structure, and the groove provided at the bottom of the knob 204 is adapted to the limit block 107, and the knob 204 is limited by the limit block 107, thereby ensuring that the knob 204 will not separate from the side wall of the box body 101;

[0074] The end of the rotating rod 204a is matched with the groove 202a, and the knob 204 can be limited by the set groove 202a to ensure that the position of the knob 204 in the plane direction will not be offset; in this state, the knob 204 can rotate normally, and the rotation of the knob 204 drives the push rod 202 to rotate, thereby pushing the pressure plate 203 connected to the end of the push rod 202 to move.

[0075] In this embodiment, when in use, the operator stretches the end of the connecting rope 105 for a certain distance, and then winds the end of the connecting rope 105 around the outside of the larger cylinder, and then fastens the connecting rope 105 to the outside of the cylinder; then a fixed hanging point can be provided for the staff during operation, and then the connecting rope 105 is pulled out for a certain distance and the distance of the connecting rope 105 being extended needs to be fixed; then the knob 204 is turned, and the rotating rod 204a connected to the end of the knob 204 is located inside the groove 202a and rotates, and the rotation of the rotating rod 204a drives the push rod 202 to rotate, so that the push rod 202 moves downward along the axial direction of the screw sleeve 201, and as the knob 204 is continuously turned, the push rod 202 moves downward along the axial direction of the screw sleeve 201. The push rod 202 is rotated, and the rotation of the rotating rod 204a drives the push rod 202 to rotate. The push rod 202 is gradually spirally fed downward along the axis of the screw sleeve 201, so that the rotating rod 204a and the groove 202a are separated by a certain distance; then the bottom surface of the pressing plate 203 is close to the surface of the connecting rope 105, so that the pressing plate 203 presses the connecting rope 105, and presses the connecting rope 105 against the inner wall of the rope outlet 101a; then the connecting rope 105 is fixed on one side of the limiting rod 101b; at the same time, a stable triangular structure can be formed by the setting of the limiting rod 101b, and then the extended length of the connecting rope 105 can be fixed by friction; thereby ensuring that the staff is more stable during use.

[0076] In summary, by cooperating between the push rod 202 and the screw sleeve 201, the pressure plate 203 presses the connecting rope 105 against the inner wall of the rope outlet 101a; thereby ensuring that the connecting rope 105 is fixed on one side of the limiting rod 101b, and then the connecting rope 105 remains fixed after being extended to a fixed distance; and a stable hanging point can be provided for the operator.

[0077] Example 3

[0079] It should be noted that the end of the connecting rope 105 is connected and fixed to the end of the hook 301, and the safety buckle 302 can rotate along the axis and close the opening of the hook 301; at the same time, the safety buckle 302 is internally connected with a limiting device, which can ensure that the safety buckle 302 closes the opening of the hook 301, so that the connecting rope 105 can be quickly formed into a ring-shaped closed ring; thereby facilitating the fixing of the connecting rope 105 on the outside of the cylinder; and then the fixing of the hanging point can be quickly completed.

[0080] Furthermore, when a stable mooring point is formed by overlapping the connecting rope 105, after the connecting rope 105 is wrapped around the cylinder for one circle, the connecting rope 105 is divided into two groups of single lines; then the hook 301 connected to the end of the connecting rope 105 is overlapped on the outside of another group of connecting ropes 105; then the opening of the hook 301 is closed by the safety buckle 302; then the connecting rope 105 is formed into a closed and wrapped around the outside of the cylinder, and the end of the connecting rope 105 can be fixed on the outside of the cylinder; thereby, a stable mooring point can be quickly formed on the outside of the cylinder; making it easier and more convenient for the staff to operate.
