[0049] 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.

[0050] 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.

[0051] Example 1

[0052] Reference Figure 1 to Figure 4, which is the first embodiment of the present invention, and this embodiment provides a safety belt hanging device for edge work, which includes a fixing unit 100, including an outer cover 101, a winding shaft 102 arranged on the inner side of the outer cover 101, a top plate 103 arranged at the end of the winding shaft 102, a swinging member 104 arranged on both sides of the top plate 103, limit blocks 105 arranged on both sides of the top of the top plate 103, a fixing member 106 arranged on the surface of the outer cover 101, and a tension spring 107 arranged at the end of the limit block 105.

[0053] It should be noted that the outer cover 101 has a hollow structure, which can facilitate the redundant connecting rope to be arranged inside the outer cover 101, thereby ensuring that the connecting rope can have a longer extension amount; and the arranged winding shaft 102 can be arranged inside the outer cover 101 and rotate; the connecting rope can be wound around the outer side of the winding shaft 102 by rotating; and the arranged top plate 103 is adapted to the winding shaft 102, and the top plate 103 moves along the inner wall of the winding shaft 102; and the winding shaft 102 can generate centrifugal force during the rotation process; the winding shaft During the rotation of 102, the swinging member 104 can be driven to rotate; during the rotation of the swinging member 104, the top plate 103 can be pushed to move in the vertical direction; there are two groups of limit blocks 105; the two groups of limit blocks 105 are arranged opposite to each other, and elastic reset members are connected between the limit blocks 105, so that the limit blocks 105 can be easily pulled to make their ends embedded in the inner side of the circular block 201; when the limit blocks 105 pass through the circular block 201 and are stuck to the inner side of the fixing member 106, the position of the winding shaft 102 is in a fixed position.

[0054] Furthermore, the reset unit 200 includes a circular block 201 arranged on the surface of the outer cover 101, a fixed sleeve 202 arranged on the surface of the circular block 201, a pressing rod 203 arranged on the inner side of the fixed sleeve 202, a movable sleeve 205 arranged on the outer side of the fixed sleeve 202, a connecting block 204 arranged on the inner side of the movable sleeve 205, and a limiting member 206 arranged on the inner wall of the circular block 201.

[0055] It should be noted that the interior of the circular block 201 is a hollow structure, and the bottom of the circular block 201 is in contact with the outer cover 101; and the space inside the circular block 201 provides a certain movement space for the limit block 105 and the top of the winding shaft 102, the fixed sleeve 202 and the circular block 201 are welded and fixed, the bottom of the pressing rod 203 is connected to the fixed rod, and the fixed rod passes through the inside of the circular block 201; and the connecting block 204, the fixed sleeve 202 and the pressing rod 203 cooperate with each other, so as to drive the movable sleeve 205 to move in the opposite direction, and the movable sleeve 205 can drive the end of the limit piece 206 to move during the movement; and the limit piece 206 is made of elastic metal; during the process of the movable sleeve 205 driving the end of the limit piece 206 to move, the limit piece 206 will deform and bend.

[0056] When in use, for steel pipe poles with large diameters and no ladders, trees, and objects that can be fixed at a long distance, it is necessary to provide a fixed hanging point for the operator; when the operator is weightless, the connecting rope is driven to move, and the connecting rope rotates along the axis direction of the winding shaft 102. In the weightless state, the connecting rope moves quickly, thereby driving the winding shaft 102 to rotate at a high speed. The centrifugal force generated by the rotation of the winding shaft 102 can drive the swinging member 104 to rotate, and the swinging member 104 pushes the top plate 103 to move along the axis direction of the winding shaft 102 during the rotation; during the movement of the top plate 103, its end squeezes the limit block 105, so that the two groups of limit blocks 105 are separated from each other, and the limit block 105 penetrates the circular block 201 and extends to its outside, and the limit block 105 is inserted into the inner side of the fixing member 106, so that the position between the limit block 105 and the fixing member 106 is fixed; thereby, the winding shaft 102 cannot rotate, and the connecting rope will not continue to be stretched; in this state, the staff can be protected to a certain extent, thereby ensuring the safety of the staff's work;

[0057] In the above state, when the length of the connecting rope needs to be changed, the pressing rod 203 is pushed, and the pressing rod 203 moves in the vertical direction to squeeze the connecting block 204. Through the cooperation between the connecting block 204 and the fixed sleeve 202, the movable sleeve 205 can be driven to move in the direction close to the pressing rod 203; during the movement of the movable sleeve 205, the end of the limiting member 206 can be driven to move, and after the limiting member 206 is subjected to the vertical upward force, the limiting member 206 undergoes a certain deformation; at this time, the limiting member 206 will not limit the movement of the limiting block 105, so that the two groups of limiting blocks 105 are close to each other, and the limiting block 105 and the fixing member 106 are separated, and then the winding shaft 102 can be rotated to change the length of the extending connecting rope.

[0058] In summary, the present invention can provide a fixed hanging point for the operator through the setting of the connecting unit, thereby ensuring the safety of the operator; when the operator loses weight and falls, the expansion and contraction amount of the connecting rope can be fixed by the setting of the fixing unit, so that the length of the connecting rope remains unchanged, thereby ensuring the operating safety of the staff.

[0059] Example 2

[0060] Reference Figure 1 to Figure 6 , which is the second embodiment of the present invention, and which is different from the first embodiment in that: it also includes: the outer cover 101 includes a support sleeve 101a arranged on its end surface; the winding shaft 102 is movably connected with the top plate 103, and the top plate 103 passes through the outer cover 101 and extends to the outside thereof; the swing member 104 includes a connecting rod 104a, and a sphere 104b arranged at the end of the connecting rod 104a; the connecting rod 104a includes a rotating shaft 104a-2 arranged on its side wall, and the rotating shaft 104a-2 passes through the side wall of the winding shaft 102 and extends to the inside thereof.

[0061] It should be noted that a support sleeve 101a is connected to the surface of the outer cover 101, and the winding shaft 102 can rotate along the axial direction of the center of the outer cover 101; the connecting rod 104a is an L-shaped structure, the rotating shaft 104a-2 is located at the turning point of the connecting rod 104a, and the connecting rod 104a rotates along the axial direction of the rotating shaft 104a-2; the winding shaft 102 drives the swinging member 104 to rotate during its rotation; under the action of centrifugal force, the sphere 104b is located at the side wall gradually away from the winding shaft 102.

[0062] Furthermore, the top plate 103 includes guide rails 103a arranged on both sides thereof, an extrusion block 103b arranged on the end face of the top plate 103, and a cylinder 103c arranged on the end face opposite to the extrusion block 103b; the connecting rod 104a also includes guide columns 104a-1 arranged on both sides of the end; the guide rails 103a are adapted to the guide columns 104a-1, and the cylinder 103c penetrates the winding shaft 102 and extends into the interior thereof; the swinging of the swinging member 104 can drive the top plate 103 to move in the vertical direction.

[0063] It should be noted that during the rotation of the swinging member 104, the connecting rod 104a rotates along the axial direction of the rotating shaft 104a-2, and the guide column 104a-1 moves inside the guide rail 103a as the connecting rod 104a flips over. During the movement of the guide column 104a-1, the top plate 103 is pushed to move along the axial direction of the winding shaft 102; as the winding shaft 102 rotates, the end of the top plate 103 is driven to penetrate into the inner side of the circular block 201.

[0064] Furthermore, there are two groups of limit blocks 105, which are connected by a tension spring 107; the limit block 105 includes a connecting plate 105a arranged at its end; and the end of the cylinder 103c is in contact with the connecting plate 105a.

[0065] It should be noted that the two groups of limit blocks 105 are arranged opposite to each other along the axial direction, and the ends of the limit blocks 105 pass through the circular block 201 and extend to the outside thereof, and a fixing column is provided at the end of the connecting plate 105a; and the two ends of the tension spring 107 are hung on the outside of the fixing column; and the number of the tension springs 107 is two groups, and the two groups of tension springs 107 are symmetrically arranged at the ends of the limit blocks 105; under normal circumstances, under the tension of the tension springs 107, the ends of the limit blocks 105 are immersed in the inner side of the circular block 201, and the tension springs 107 and the limit blocks 105 cooperate to form a rectangular structure, and the rectangular structure formed can provide movement space for the pressing rod 203.

[0066] Furthermore, the circular block 201 is movably connected to the support sleeve 101a, the bottom of the circular block 201 is arranged inside the support sleeve 101a; the limit block 105 is arranged inside the circular block 201; and the fixing member 106 is sleeved on the outside of the circular block 201.

[0067] It should be noted that the fixing member 106 is welded and fixed to the supporting sleeve 101a, and the fixing member 106 is an annular internal gear structure; the fixing member 106 is sleeved on the outside of the circular block 201, and the limiting block 105 is set to penetrate the circular block 201 and extend to its outside, and the limiting block 105 is adapted to the tooth gap opened inside the fixing member 106; after the limiting block 105 is inserted into the inside, the rotation of the circular block 201 can be limited; and the top plate 103 is set to penetrate the circular block 201 and extend to the inside, and the top plate 103 moves along the vertical direction; the rotation of the circular block 201 can drive the top plate 103 to rotate.

[0068] Furthermore, the fixing sleeve 202 includes a through hole 202a opened therein; the pressing rod 203 includes a fixing rod 203a arranged on its end surface; the fixing rod 203a passes through the fixing sleeve 202 and extends to the inner side of the circular block 201, and the fixing rod 203a is arranged between the two sets of limit blocks 105.

[0069] It should be noted that the fixing rod 203a is a rod-shaped structure, and the fixing rod 203a can pass through the fixing sleeve 202 and extend to the inside of the circular block 201; the end of the fixing rod 203a is located between the two sides of the limit block 105, and the ends of the limit block 105 are relatively arranged to provide a certain space for the fixing rod 203a, thereby ensuring that the fixing rod 203a has a certain movement space.

[0070] Furthermore, the movable sleeve 205 includes a first slider 205a arranged on its inner wall, and a rectangular plate 205b arranged at the end of the movable sleeve 205; the fixed rod 203a includes an oblique opening 203a-1 opened inside it; the connecting block 204 is adapted to the oblique opening 203a-1, and the connecting block 204 moves along the through direction of the through hole 202a; both ends of the connecting block 204 are in contact with the first slider 205a; the limiting member 206 passes through the circular block 201 and extends to its outside, and the end of the limiting member 206 is in contact with the rectangular plate 205b.

[0071] Preferably, the connecting block 204 is a Z-shaped structure, wherein the end of the connecting block 204 is an inclined surface at A; the center of the connecting block 204 is an inclined surface at B and a horizontal surface C located on the side wall of the connecting block 204; the inclined surface at A contacts the first slider 205a, and the inclined surface at B contacts the inner wall of the oblique opening 203a-1; and the horizontal surface C is set flush with the inner wall of the through hole 202a; so that the connecting block 204 can move along the track inside the through hole 202a; the pressing rod 203 moves along the vertical direction. During the movement, the inner wall of the fixed rod 203a squeezes the connecting block 204, and then the connecting block 204 moves along the internal trajectory of the through hole 202a; during the movement of the connecting block 204, the first slider 205a is squeezed, so that the movable sleeve 205 moves toward the direction close to the pressing rod 203; during the movement of the first slider 205a, the end of the limiting member 206 is driven to move upward; and the limiting member 206 is made of elastic metal material, and during the upward movement of the rectangular plate 205b, the limiting member 206 can be driven to undergo a certain deformation.

[0072] Furthermore, both sides of the ends of the extrusion block 103b contact the connecting plate 105a; the limit block 105 passes through the circular block 201 and extends to its outside; the limit block 105 is inserted into the inner side of the fixing member 106, and the end of the limit block 105 is adapted to the fixing member 106; the side wall of the limit member 206 contacts the connecting plate 105a.

[0073] It should be noted that the rotation of the winding shaft 102 drives the swinging member 104 to rotate through the eccentricity; the rotation of the swinging member 104 lifts up the top plate 103, so that the top plate 103 moves along the axial direction of the winding shaft 102; during the movement of the extrusion block 103b, the two sides of its end portions squeeze the connecting plate 105a; the limit block 105 penetrates the circular block 201 and extends to its outside; the moving end of the limit block 105 can be inserted into the inner side of the fixing member 106; in this state, the end of the limit member 206 contacts the surface of the connecting plate 105a; the limit block 105 can be limited by the set limit member 206.

[0074] Furthermore, the movement of the pressing rod 203 toward the circular block 201 can drive the movable sleeve 205 to move in the opposite direction; one end of the limiting member 206 moves upward to deform it, and the side wall of the limiting member 206 is staggered from the movement trajectory of the connecting plate 105a; the bottom of the fixing rod 203a contacts the top surface of the extrusion block 103b.

[0075] It should be noted that, during the movement of the pressing rod 203 toward the direction approaching the circular block 201, the movable sleeve 205 can be driven to move toward the direction away from the circular block 201; during the movement of the movable sleeve 205, the first slider 205a is driven to move, and the first slider 205a contacts the end face of the limiting member 206; during the movement of the movable sleeve 205, the limiting member 206 can be driven to undergo a certain deformation, so that the end face of the limiting member 206 and the position of the connecting plate 105a are staggered; at this time, under the action of the rebound force of the tension spring 107, the two groups of limiting blocks 105 can be pulled closer to each other; thereby, the end of the limiting block 105 is immersed in the inner side of the circular block 201, and then the limiting of the circular block 201 can be released.

[0076] During use, the staff will make the rope rotate rapidly around the axis of the winding shaft 102 in a weightless state. The winding shaft 102 generates centrifugal force during high-speed rotation, and the centrifugal force generated by the rotation of the winding shaft 102 can drive the swinging member 104 to rotate; as the swinging member 104 rotates, the top plate 103 can be driven to move along the axis direction, and the two sides of the end of the squeezing block 103b can squeeze the side walls of the connecting plate 105a during the movement. After the limit block 105 is compressed, the end of the limit block 105 passes through the circular block 201 and extends to its outside; the end of the connecting plate 105a continuously squeezes the limit block during the movement. 206, after the limiting member 206 is compressed, it undergoes a certain deformation; when the end of the limiting block 105 is inserted into the inner side of the fixing member 106, the end of the limiting member 206 contacts the surface of the connecting plate 105a; thus, the connecting plate 105a can be limited by the provided limiting member 206; at this time, the circular block 201 is relatively fixed to the fixing member 106, and the fixing member 106 is fixedly connected to the outer cover 101, thereby ensuring that the position between the circular block 201 and the outer cover 101 is fixed, so that the rope wound on the outside of the reel 102 will not rotate; the length of the rope can be kept unchanged, thereby ensuring that the device protects the operator;

[0077] When the rope needs to be reeled in, the pressing rod 203 is pushed, and the pressing rod 203 approaches the circular block 201; the inner wall of the oblique opening 203a-1 squeezes the connecting block 204, and the connecting block 204 moves along the track of the through hole 202a through the limit of the through hole 202a; the movement of the connecting block 204 drives the movable sleeve 205 to move away from the circular block 201; then the first slider 205a drives the limiting member 206 to move, so that the limiting member 206 is deformed; thereby, the position of the limiting member 206 is staggered with the connection plate 105a. ; Then, under the elastic force of the tension spring 107, the two sets of limit blocks 105 are driven to move closer to each other; so that the end of the limit block 105 can be immersed in the inner side of the circular block 201; when the pressing rod 203 moves toward the circular block 201, the end of the fixed rod 203a continuously contacts the end of the extrusion block 103b, so that the extrusion block 103b is reset; so that the swinging member 104 can be restored to a state close to the side wall of the winding shaft 102; then at this time, rotating the circular block 201 can drive the winding shaft 102 to rotate, and the rope can be wound around the outside of the winding shaft 102.

[0078] In summary, the provided pressing rod 203 can drive the movable sleeve 205 to move in the opposite direction thereof, and during the movement of the movable sleeve 205, the limit member 206 can be deformed, so that the position of the limit member 206 and the connecting plate 105a are staggered; thereby, it is convenient to release the fixation of the telescopic length of the rope; at the same time, the top plate 103 can be pushed to move, so that the top plate 103 drives the swing member 104 to reset; thereby, it is better to fix the length of the rope next time.

[0079] Example 3

[0080] Reference Figure 1 to Figure 6 , which is the third embodiment of the present invention, is different from the previous two embodiments in that it includes: a connecting unit 300, which includes a connecting rope 301 wound around the outside of the winding shaft 102, and the end of the connecting rope 301 passes through the outer cover 101 and extends to the outside thereof; one end of the connecting rope 301 is connected to a hook 302, and the other end is provided with a hanging ring 304; a safety buckle 303 is provided at the opening of the hook 302.

[0081] It should be noted that the safety buckle 303 can close the opening position of the hook 302; and the connecting rope 301 is fixedly connected to the hook 302, and the lifting ring 304 is fixedly connected to the connecting rope 301, and the lifting ring 304 is connected to the safety belt through the existing D-shaped buckle, thereby ensuring that the safety rope can provide a certain safety guarantee for the staff.

[0082] During use, when a worker encounters a columnar structure with a larger diameter during operation, the worker will wrap the hook 302 around the object and then buckle the opening of the hook 302 on the outside of the connecting rope 301. The safety buckle 303 blocks the opening of the hook 302, thereby forming a stable hanging point around the columnar object. When the worker loses weight, the expansion and contraction amount of the connecting rope 301 can be fixed according to the steps in Example 2. When the worker loses weight, the rope is tightened, thereby forming a pulling force on the worker, ensuring the safety of the worker to a certain extent.
