[0003] For example, a convenient double-hook safety rope with publication number CN220175905U is disclosed. The utility model relates to the technical field of safety ropes. The top plate is movably arranged in a control groove provided on the inner top wall of the hook. Several No. 1 springs are fixedly arranged on the upper part of the top plate. The moving block is movably arranged in a rectangular groove provided on the right side wall of the hook. A strip rod is movably arranged in the strip groove. The upper end of the strip rod is fixedly connected to the top plate. The No. 2 springs are respectively fixedly arranged in the strip groove at the front and rear sides of the strip rod. The left end of the No. 2 spring is fixedly connected to the moving block. A resistance block is arranged on the left side wall of the moving block. The lower part of the resistance block is resisted on the lock buckle. It can not only facilitate the connection and disassembly of the hook and the escalator during the climbing process of the staff, but also improve the climbing effect.

[0004] Most of the above-mentioned double-hook safety ropes have improved their overall structure. During use, the existing double-hook safety ropes are mostly movable positioning structures, that is, when they are subjected to force, they will become unlocked. They cannot adaptively self-lock according to the situation under the state of force, thereby ensuring the safety of the user to the greatest extent. Utility Model Content

[0005] The purpose of the utility model is to provide a self-locking double-hook safety rope to solve the problem in the background technology that most of the positioning structures are movable during use, that is, when they are subjected to force, they will be unlocked, and they cannot adaptively perform self-locking processing according to the situation under the state of force, so as to ensure the safety of the user to the greatest extent.

[0006] To achieve the above object, the utility model provides the following technical solution: a self-locking double-hook safety rope, comprising a preset base and a safety rope, wherein the lower end of the preset base is fixedly connected to the safety rope, and the inner end of the preset base is rotatably connected to a torsion spring positioning buckle;

[0007] A guide slot is provided on the inner side of the preset base, and a movable docking block is nested and installed on the outer end of the guide slot, and a first spring is fixed on the outer side of the movable docking block, and the first spring and the inner side of the preset base are docked with each other. An auxiliary positioning structure is provided at the inner end of the preset base, and the self-locking processing of the preset base and the torsion spring positioning buckle under the stress state is realized through the auxiliary positioning structure.

[0008] Furthermore, the auxiliary positioning structure is provided with a traction rope, and the traction rope is docked at the lower end of the movable docking block, and the traction rope extends along the inner side of the preset base, a first resistance piece is nested and installed on the inner side of the edge end of the preset base, and a second spring is fixedly connected to the upper end of the first resistance piece, the outer lower end of the first resistance piece is docked with the end of the traction rope, and a locking groove is provided at the end of the preset base.

[0009] Furthermore, a reserved accommodating groove is provided at the upper end of the torsion spring positioning buckle, and a first airbag is nested and installed inside the reserved accommodating groove, a gas hose is docked at the lower end of the first airbag, and the gas hose passes through and docks along the inner side of the torsion spring positioning buckle, a second airbag is docked at the end of the gas hose, and the second airbag is arranged on the inner side of the torsion spring positioning buckle, a second resistance piece is docked at the upper end of the second airbag, and the second resistance piece corresponds to the locking groove position.

[0010] Furthermore, the movable docking block slides outward along the inner side of the preset base body during the process of being compressed, and the first spring at the inner end is pressed to perform elastic support work.

[0011] Furthermore, during the upward movement of the movable docking block, a traction structure is formed with the first resisting member through the traction rope, and the upper end of the first resisting member moves outward along the inner end of the preset base through the second spring.

[0012] Furthermore, when the first resisting member is forced to move downward, pressure is applied inward to the first airbag in contact with it, so that negative pressure movement is formed along the inner side of the reserved accommodating groove.

[0013] Furthermore, when the first airbag is pressurized, air is supplied to the interior of the second airbag at the end through the air supply hose, causing it to expand and push the second resistance member on the outside to move, thereby engaging with the interior of the locking groove to perform self-locking work.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The self-locking double-hook safety rope is provided with an auxiliary positioning structure. When the whole safety rope is stretched straight by force, the movable docking block at the inner end thereof will move inwards accordingly, and then the first abutment member will be driven downwards by the corresponding traction rope, so that it cooperates with the preset base and the torsion spring positioning buckle to perform self-locking work. Under the condition of force, the rope will not be unfastened. Under the condition of force, the rope will be self-adaptively self-locked according to the situation, thereby ensuring the safety of the user to the greatest extent.

[0016] Furthermore, in the process of the first resistance member being forced to move downward, it will apply pressure inward to the first airbag in contact, so that negative pressure is formed along the inner side of the reserved accommodating groove, so that air is supplied to the interior of the second airbag at the end through the air supply hose, so that it expands and pushes the second resistance member on the outside to move in position, thereby engaging with the interior of the locking groove for secondary self-locking. In the process of the first resistance member positioning between the preset base and the torsion spring positioning buckle, the self-moving second resistance member is used to perform secondary protection treatment, thereby improving the safety of the device.
