[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] Example 1, by Figures 1-7 The present invention includes a mounting ring 1, a mounting plate 4 fixedly mounted on the bottom of the mounting ring 1, a hook 5 fixedly mounted on the outer side of the mounting plate 4, an anti-detachment mechanism 2 provided between the mounting plate 4 and the hook 5, and a locking mechanism 3 provided on the outer side of the hook 5.

[0030] In Example 2, based on Example 1, the anti-detachment mechanism 2 includes a crossbar 201 fixed to the inner side of the hook 5. A toothed plate 202 is movably sleeved on the outer side of the crossbar 201. Two base plates 209 are symmetrically fixedly connected to the bottom of the mounting plate 4. The toothed plate 202 is located between the two base plates 209. A connecting shaft 2010 located below the toothed plate 202 is rotatably connected between the two base plates 209. A sleeve 2018 is fixedly installed on the outer side of the connecting shaft 2010. An external gear 2013 is fixedly installed on the outer side of the sleeve 2018. The external gear 2013 meshes with the toothed plate 202. A clamping plate 203 is fixedly installed on the outer side of the sleeve 2018. The hook 5... The inner side of the hook 5 is provided with a slot 2019, and the card plate 203 is inserted into the slot 2019. The outer side of the hook 5 is movably sleeved with a slider three 2016. The outer side of the slider three 2016 is fixedly connected with a connecting frame 205. The bottom of the connecting frame 205 is fixedly connected with an arc-shaped clamping plate 204. The outer side of the hook 5 is fixedly sleeved with an outer ring 207 located above the slider three 2016. A spring one 206 is fixedly connected between the outer ring 207 and the slider three 2016. The spring one 206 is sleeved on the outer side of the hook 5. The bottom of the mounting plate 4 is fixedly connected with a base block 2011. The end of the crossbar 201 away from the hook 5 is fixedly connected to the base block 2011. The toothed plate 202 and the... A spring 2012 is fixedly connected between the bottom blocks 2011. The spring 2012 is sleeved on the outside of the crossbar 201. A limit block 2022 is fixedly connected to the top of the toothed plate 202. A limit groove 2021 is provided at the bottom of the mounting plate 4. The limit block 2022 is slidably connected to the limit groove 2021. When the toothed plate 202 slides along the crossbar 201, it drives the limit block 2022 to slide in the limit groove 2021, ensuring the stability of the toothed plate 202 when sliding. A limit groove 2020 is provided on the outside of the hook 5. A limit block 2015 is fixedly connected to the inside of the slider 2016. The limit block 2015 is connected to the limit groove 2020. 020 Sliding connection: When slider three 2016 slides along hook 5, it drives limit block one 2015 to slide in limit groove one 2020, ensuring the stability of slider three 2016 when sliding. Slider one 208 is fixedly connected to the side of toothed plate 202 away from bottom block 2011. Slider one 208 is movably sleeved on the outside of crossbar 201. Movable rod one 2017 is rotatably connected to the bottom of slider one 208. Slider two 2014 located below slider three 2016 is movably sleeved on the outside of hook 5. The bottom end of movable rod one 2017 is rotatably connected to the outside of slider two 2014, and movable rod one 2017 passes through connecting frame 205.

[0031] First, push the clamping plate 203 to separate it from the clamping slot 2019, causing the sleeve 2018 and connecting shaft 2010 to rotate, and driving the external gear 2013 to rotate. Since the external gear 2013 is meshed with the toothed plate 202, the toothed plate 202 is driven to slide along the crossbar 201 and approach the bottom block 2011. At this time, the second spring 2012 is compressed, and the first slider 208 slides along the crossbar 201. Through the movable rod 2017, the second slider 2014 is driven to slide upward along the hook 5. When the second slider 2014 contacts the third slider 2016, it continues to rise, pushing the third slider 2016 upward. At this time, the first spring 2012 is compressed. 206 is compressed, and the arc-shaped clamp 204 is raised through the connecting frame 205. Then, the basket rope is hung inside the hook 5, and the basket rope is located directly below the arc-shaped clamp 204. Then, the clamp 203 is released. At this time, the clamp 203 rotates under the action of the second spring 2012 and is locked in the slot 2019 to limit the basket rope. At the same time, the second slider 2014 descends to release the restriction effect on the third slider 2016. At this time, the arc-shaped clamp 204 moves downward under the action of the first spring 206 to clamp the basket rope, further limiting the basket rope and finally preventing the basket rope from slipping.

[0032] In embodiment three, based on embodiment one, the locking mechanism 3 includes a mounting frame 301 fixed to the outside of the hook 5. Two guide posts 3012 are symmetrically fixedly connected to the outside of the mounting frame 301. A side block 3011 is fixedly connected to the end of each guide post 3012 away from the mounting frame 301. Guide blocks 307 are movably sleeved on the outside of each guide post 3012, and each guide block 307 abuts against the two side blocks 3011. Insert rods 308 are fixedly connected to the bottom of each guide block 307. A slider 208 is located between the two insert rods 308. Two insertion holes 309 are symmetrically provided on the outside of the slider 208, and the inner diameter of each insertion hole 309 is equal to the outer diameter of each insertion rod 308. A U-shaped round rod 305 is fixedly connected to the top of the mounting frame 301. A lifting plate 303 is movably sleeved on the outside of the U-shaped round rod 305. A drive assembly 302 is provided below. Two movable rods 306 are symmetrically rotatably connected to the outer side of the lifting plate 303. The ends of the two movable rods 306 away from the lifting plate 303 are rotatably connected to two guide blocks 307 respectively. A lifting plate 304 located above the lifting plate 303 is movably sleeved on the outer side of the U-shaped rod 305. Two connecting rods 3010 are symmetrically fixedly connected between the lifting plate 304 and the connecting frame 205. A sleeve block 3016 is fixedly sleeved on the middle of the outer side of the U-shaped rod 305. A screw 3014 is fixedly connected between the sleeve block 3016 and the mounting frame 301. The lifting plate 303 and the lifting plate 304 are both sleeved on the outer side of the screw 3014 and do not contact the screw 3014. A screw cylinder 3017 located above the lifting plate 304 is threadedly sleeved on the outer side of the screw cylinder 3014. A handwheel 3015 is fixedly installed on the outer side of the screw cylinder 3017.

[0033] After the arc-shaped clamping plate 204 clamps the suspended platform rope, first rotate the second handwheel 3015 to drive the second screw barrel 3017 to rotate. Since the screw barrel 3017 is threaded onto the outside of the screw rod 3014, the screw barrel 3017 moves downward while rotating until it abuts against the top of the lifting plate 304, limiting the arc-shaped clamping plate 204 and achieving a firm clamping of the suspended platform rope. When the clamping plate 203 is locked in the clamping groove 2019, the lifting plate 303 slides upward along the U-shaped round rod 305. Through the two movable rods 306, the two guide blocks 307 slide along the two guide posts 3012 respectively. At the same time, the two insert rods 308 approach each other until they are inserted into the two insert holes 309 respectively, completing the clamping of the first slider 208. Finally, the clamping plate 203 is limited to prevent it from rotating under the action of external force, ensuring that the suspended platform rope can always be hung in the hook 5.

[0034] In Embodiment 4, based on Embodiment 1, the drive assembly 302 includes a screw barrel 3021 threaded onto the outside of the screw 3014, a handwheel 3024 fixedly mounted on the outside of the screw barrel 3021, a bottom ring 3013 fixedly connected to the bottom of the lifting plate 303, the bottom ring 3013 being sleeved on the outside of the screw 3014 but not in contact with the screw 3014, and a plurality of top posts 3022 fixedly connected at equal angles to the top of the screw barrel 3021, each top post 3022 having a ball bearing 3023 mounted on its top end below the bottom ring 3013;

[0035] First, rotate the handwheel 3024 to drive the screw barrel 3021 to rotate. Since the screw barrel 3021 is threaded onto the outside of the screw 3014, the screw barrel 3021 moves upward while rotating. When all the balls 3023 are in contact with the bottom of the bottom ring 3013, continue to rotate the screw barrel 3021 to make it rise and push the bottom ring 3013 and the lifting plate 303 upward. Finally, the two insert rods 308 are inserted into the two insertion holes 309 respectively to limit the slider 208.
