Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
As shown in fig. 1, the invention comprises a box body 1, and a speed reducing mechanism and a winding mechanism which are arranged in the box body 1, wherein the speed reducing mechanism is connected with the winding mechanism through a pull rope 2, and the speed reducing mechanism is positioned above the winding mechanism.
The winding mechanism comprises a winding roller 3, the left end and the right end of the winding roller 3 are fixedly connected with rotating shafts 4 respectively, the winding roller 3 is rotationally connected with the left side wall and the right side wall of the box body 1 through the rotating shafts 4 arranged at the left end and the right end, one rotating shaft 4 extends out of the box body 1 and is connected with a handle 5, and the winding roller 3 can rotate through rotating the handle 5. The left rotating shaft 4 and the right rotating shaft 4 are respectively sleeved with a sleeve 6, each sleeve 6 is fixedly connected with a wire drawing 7, the two wire drawing 7 penetrate out of the bottom plate of the box body 1, and the tail ends of the two wire drawing 7 are connected with a stress plate 8.
The speed reducing mechanism comprises a left mounting plate 9 and a right mounting plate 9 which are arranged in parallel, the two mounting plates 9 are connected through two adjusting rods 10, the two adjusting rods 10 are arranged in parallel, each mounting plate 9 is fixedly connected with a connecting shaft 11, the mounting plates 9 are rotatably connected with the left side wall and the right side wall of the box body 1 through the connecting shafts 11, and one connecting shaft 11 extends out of the box body 1 and is connected with a rocker 12. The connecting shaft 11 extending out of the box body 1 is also connected with a ratchet wheel 13, the outer wall of the box body 1 is rotatably connected with a pawl 14 matched with the ratchet wheel 13, and the ratchet wheel 13 can only rotate in one direction but cannot be turned over due to the existence of the pawl 14.
One end of the pull rope 2 is fixed on the winding roller 3, the other end of the pull rope is firstly wound along the winding roller 3 for a plurality of circles, then penetrates through the space between the two adjusting rods 10, finally penetrates out of the top plate of the box body 1 to be connected with the hook 16, and the pull rope 2 can freely penetrate through the top plate of the box body 1. The wear-proof sheath 15 is sleeved on the pull rope 2 between the hook 16 and the top plate of the box body 1, the wear-proof sheath 15 can protect hands of a user, and the user can avoid hand injury by holding the wear-proof sheath 15 when falling down.
When an emergency drop is required, the hook 16 is fixed on articles such as indoor furniture and guardrails, or connecting pieces are pre-embedded on a wall body in advance, the hook 16 is hooked on the connecting pieces, after the hook 16 is fixed firmly, a user adjusts the speed reducing mechanism according to the weight condition of the user, specifically, the rocker 12 is rocked to drive the two adjusting rods 10 to rotate, the wiring mode of the pull rope 2 on the two adjusting rods 10 can be changed when the two adjusting rods 10 rotate, the specific wiring modes are shown in fig. 2, 3, 4, 5 and 6, when the state of the pull rope is in the state of fig. 2, the pull rope 2 can freely pass through the two adjusting rods 10, and the friction force between the two adjusting rods 10 and the pull rope 2 is gradually increased along with the gradual increase of the clockwise rotation angle of the speed reducing mechanism along with the gradual increase of the horizontal state, so that the difficulty of the pull rope 2 passing through the speed reducing mechanism is also gradually increased. The application is convenient for based on above-mentioned speed reduction principle, to the user that the body is great properly increase reduction gears's rotation angle, alright increase stay cord 2 and reduction gears's frictional force to reduce the release rate of stay cord 2, just also reduced user's decline speed, decline speed can carry out effective control, thereby has guaranteed the security when different weight crowd use. The specific experiment shows that: when the speed reducing mechanism rotates clockwise for 360 degrees along the horizontal state, the falling speed is basically 30 meters per minute when the weight of the speed reducing mechanism is 50 kg; when the speed reducing mechanism rotates clockwise for 450 degrees along the horizontal state, the falling speed is basically 30 meters per minute when the weight of the speed reducing mechanism is 70 kg; when the speed reducing mechanism rotates clockwise for 540 degrees along the horizontal state, the falling speed is basically 30 meters per minute when the weight of the speed reducing mechanism is 90 kg; therefore, the weight range of the user can be adjusted to float 20kg every 90 degrees based on 360 degrees of clockwise rotation of the speed reducing mechanism along the horizontal state, and the user can rotate the speed reducing mechanism by a corresponding angle according to the weight of the user. For example, one user weighing 30 kg, the speed reduction mechanism is rotated by 270 °, and one user weighing 110 kg, the speed reduction mechanism is rotated by 630 °. After the speed reducing mechanism is set, under the cooperation of the ratchet wheel 13 and the pawl 14, the speed reducing mechanism can keep a set angle, then a user can sit on the stress plate 8, then hug the box body 1 tightly, hold the anti-abrasion sheath 15 by hands, release the pull rope 2 on the winding roller 3 step by means of self gravity, and drop to the ground step by step.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
