[0026] 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.

[0027] 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.

[0028] 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.

[0029] Example 1

[0030] Reference Figure 1~Figure 2 , which is the first embodiment of the utility model, and this embodiment provides a self-locking safety rope buckle, which solves the problem of heavy workload in installing scaffolding and pulling safety nets before maintenance, and includes a main body 100, a clamping assembly 200, and a rotating assembly 300.

[0031] Specifically, the main body 100 includes a base 101 and a hook 102 . The hook 102 is rotatably disposed outside the base 101 . The hook 102 can rotate around the base until the other end of the hook 102 contacts the outside of the base 101 to be locked.

[0032] Preferably, there is an arc-shaped recess at the turning point of the hook 102, and the engaging member 201 is located in the arc-shaped recess.

[0033] Furthermore, the clamping assembly 200 includes a clamping member 201 , a pushing member 202 , and a connecting member 203 . The clamping member 201 is installed on the inner side of the hook 102 through the connecting member 203 , and the pushing member 202 is in contact with and connected to the outer bottom end of the clamping member 201 .

[0034] Furthermore, the rotating assembly 300 includes a rotating member 301 and a locking member 302 . The rotating member 301 is installed at one end of the hook 102 close to the base 101 , and the locking member 302 movably connects the hook 102 and the base 101 .

[0035] When in use, the worker ties a knot in the safety rope and puts it on the hook 102, and the rope slides into the arc-shaped recess of the hook 102. When the worker pulls hard, the rope is stuck in the engaging member 201, and the engaging member 201 moves downward, thereby pushing the pushing member 202 to move. Through the connecting member 203, the restriction on the rotating member 301 is unlocked, so that the rotating member 301 can return to the original state. Since the rotating member 301 is installed at one end of the hook 102 close to the base 101, the rotation of the rotating member 301 drives the hook 102 to rotate. When it rotates to a certain angle, the locking member 302 is buckled, so that the hook 102 is fixed to the base 101. At this time, the rope is also fixed in the engaging member 201. At the same time, when the rope rotates with the hook 102, the rope at the same horizontal height is stretched, which improves the stability of the rope and reduces the problem of people falling due to forgetting.

[0036] In summary, by setting up the main body 100, the function of hanging the rope can be realized. When the rope is inserted into the locking part 201, the pushing part 202 is pushed to move, and the thrust is converted into a force to unlock the rotating part 301 through the connecting part 203, so that the rotating part 301 drives the hook 102 to rotate upward, and the hook 102 is locked with the base 101. The ropes at the same horizontal height are stretched, so that the rope state becomes tight and stretched, which improves the safety of the safety net and reduces the problem of people accidentally falling due to maintenance.

[0037] Example 2

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

[0039] Specifically, the engaging member 201 is arranged in the inner cavity of the hook 102, and includes a claw 201a, a receiving block 201b, and a telescopic rod 201c. The claw 201a is movably connected to the inner wall of the hook 102 through a connecting member 203, and the claw 201a rotates around the connecting member 203. The telescopic rod 201c is installed at the bottom of the inner wall of the hook 102, and a first spring 201c-1 is installed on the outside of the telescopic rod 201c. The telescopic rod 201c is extended and retracted according to the compression state of the first spring 201c-1. The receiving block 201b is arranged at the end of the telescopic rod 201c away from the hook 102, and is in contact and connected with the claw 201a.

[0040] Preferably, the top of the receiving block 201b is arc-shaped, which increases the contact area with the rope and facilitates the rope to be better clamped in. At the same time, one end of the receiving block 201b close to the hook 102 is set to a trapezoid, and one end of the claw 201a contacts the trapezoidal block.

[0041] Furthermore, the connecting member 203 includes a rotating column 203a and a movable track 203b. The rotating column 203a is movably connected to the claw 201a and the inner wall of the hook 102. The claw 201a rotates around the rotating column 203a. The movable track 203b is arranged on the outside of the receiving block 201b, and the movable track 203b is in contact with and connected to the protrusion on the inner wall of the hook 102. The movable track 203b on the receiving block 201b slides by contacting and connecting with the protrusion on the inner wall of the hook 102.

[0042] Furthermore, the pushing member 202 includes a pushing plate 202a, a pushing rod 202b and a moving plate 202c. Push rods 202b are correspondingly arranged on both sides of the pushing plate 202a. The pushing rods 202b are movably connected to a side of the moving plate 202c away from the receiving block 201b. When the moving plate 202c moves, the pushing rod 202b is pushed to move in the same direction, thereby driving the pushing plate 202a to rotate around the center of the circle.

[0043] Furthermore, the movable plate 202c includes a first movable rod 202c-1 and a second movable rod 202c-2. An outer end of the first movable rod 202c-1 is set as an oblique cut 202c-3, and the oblique cut 202c-3 is in contact with and connected to the receiving block 201b. When the receiving block 201b moves, the oblique cut 202c-3 is pushed to cause displacement. An installation block 202c-4 is installed at one end of the second movable rod 202c-2 away from the first movable rod 202c-1, and the installation block 202c-4 is in contact with and connected to the rotating member 301.

[0044] Furthermore, the rotating member 301 includes a rotating disk 301a, a torsion spring 301b, and a connecting rod 301c. The rotating disk 301a is movably connected to the base 101 through the connecting rod 301c. The rotating disk 301a rotates around the connecting rod 301c, and the torsion spring 301b is arranged on the outside of the connecting rod 301c.

[0045] Furthermore, a stop groove 301a-1 is provided on the turntable 301a, the stop groove 301a-1 is in contact with the mounting block 202c-4, and the number of the stop groove 301a-1 is set to be multiple.

[0046] Preferably, the torsion spring 301b is initially in a compressed state. When the mounting block 202c-4 is disengaged from the anti-rotation groove 301a-1, the turntable 301a loses resistance, that is, the torsion spring 301b can be reversed and restored to its original state.

[0047] Preferably, a magnet is provided at the bottom of the base 101. When workers need to use it, they can adsorb the base 101 to the inner wall of the water guide mechanism and use ropes to further fix the base 101 to the guide vane, making it easy for workers to assemble and disassemble.

[0048] When in use, the worker ties a safety rope and puts it on the hook 102, and the rope slides into the arc-shaped recess of the hook 102, that is, slides to the arc-shaped part of the receiving block 201b. When the worker pulls the rope downward, the receiving block 201b moves downward along the moving track 203b. Since the bottom end of the receiving block 201b is trapezoidal, when the receiving block 201b moves downward along the moving track 203b, it will squeeze the claw 201a to move upward along the bottom of the receiving block 201b, that is, it will rotate around the rotating column 203a. At this time, the claw 201a is in an open state; when the receiving block 201b is compressed to a certain extent, the first spring 201c-1 rebounds and brings the telescopic rod 201c to restore its initial state, that is, the receiving block 201b returns to its original position. At this time, the force squeezing the claw 201a disappears, and the bottom end of the claw 201a moves downward along the bottom of the receiving block 201b, so that the rope is locked between the claw 201a and the receiving block 201b, achieving preliminary fixation.

[0049] Since the oblique cut 202c-3 at one end of the outer side of the first moving rod 202c-1 is in contact with the receiving block 201b, when the receiving block 201b moves downward along the moving track 203b, the first moving rod 202c-1 is pushed a certain distance, that is, the first moving rod 202c-1 moves to the other end with the push rod 202b, and the push rod 202b is installed on the outer side of the push plate 202a, so that the push plate 202a rotates. When the push plate 202a rotates, the push rod 202b correspondingly arranged at the other end also rotates accordingly, thereby driving the second moving rod 202c-2 to produce a displacement in the opposite direction of the first moving rod 202c-1. A mounting block 202c-4 is installed at one end of the second moving rod 202c-2, and the mounting block 202c-4 is in contact with the anti-rotation groove 301a-1 on the turntable 301a, that is, when the mounting block 202c-4 is located in the anti-rotation groove 301a-1, the turntable 301a will not rotate. When the mounting block 202c-4 is out of the anti-rotation groove 301a-1, the turntable 301a will rotate due to the characteristics of the torsion spring 301b, that is, it will rotate with the hook 102. At this time, the rope is stretched, so that the state of the rope becomes tightly stretched, which improves the safety of the safety net and reduces the problem of people accidentally falling due to maintenance.

[0050] Example 3

[0051] Reference Figure 1 to Figure 6 , which is the third embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0052] Specifically, the locking member 302 includes a protrusion 302a and an interface 302b. The protrusion 302a is installed at one end of the hook 102, and the interface 302b is correspondingly arranged at the top end of the outer side of the base 101, and the inner cavity of the interface 302b is connected to a second spring 302b-1. When the protrusion 302a is inserted into the interface 302b, the second spring 302b-1 is compressed, so that the protrusion 302a is fastened in the interface 302b.

[0053] Furthermore, the hook 102 is L-shaped, and a circular groove 102a is provided at a corner of the hook 102, and the circular groove 102a is installed corresponding to the receiving block 201b.

[0054] When in use, the worker ties a knot in the safety rope and puts it on the hook 102, and the rope slides into the arc-shaped recess of the hook 102. When the worker pulls hard, the rope is stuck in the engaging member 201, and the engaging member 201 moves downward, thereby pushing the pushing member 202 to move, and unlocking the restriction on the rotating member 301 through the connecting member 203, so that the rotating member 301 can return to the original state. Since the rotating member 301 is installed at one end of the hook 102 close to the base 101, the rotation of the rotating member 301 drives the hook 102 to rotate. When it rotates to a certain angle, the protrusion 302a at the top of the hook 102 is stuck in the interface 302b due to the rotational inertia. Due to the elasticity of the second spring 302b-1, the protrusion 302a is restricted in the interface 302b. At this time, the rope is restricted in the circular groove 102a, so that the rope is initially fixed, and the increase in the rope height makes the safety ropes at the two hooks stretched, thereby increasing the stability of the safety net.

[0055] 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.
