It is obvious that the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention. Example
[0025] See also Figure 1 、 Figure 2 and Figure 5 A hook anti-drop assembly for an electric chain hoist includes a hanging ring 1, the hanging ring 1 includes a hanging ring 101, a connecting plate 103 is fixedly connected to the top of the hanging ring 101, and connecting grooves 102 are provided at the four corners of the inner cavity of the connecting plate 103. A positioning mechanism 2 is installed on the right side of the hanging ring 101;
[0026] The positioning mechanism 2 includes a fixing frame 201 and a first fixing seat 210. The top of the fixing frame 201 is fixedly connected to the bottom of the connecting plate 103. The left side of the first fixing seat 210 is fixedly connected to the right side of the hanging ring 101. The inner cavity of the first fixing seat 210 is movably connected to a screw 212. The surface of the screw 212 is fixedly connected to the adjusting plate 203. The bottom of the adjusting plate 203 is fixedly connected to a positioning seat 209. The inner cavity of the positioning seat 209 is movably connected to a movable seat 205. The bottom of the movable seat 205 is fixedly connected to a positioning plate 206. The bottom of the positioning plate 206 is fixedly connected to a positioning cover 208. The inner cavity of the positioning cover 208 is plug-connected to the surface of the hanging ring 101.
[0027] The inner cavity of the positioning seat 209 is fixedly connected with a movable shaft 204, and the surface of the movable shaft 204 is movably connected to the inner cavity of the movable seat 205. Through the above technical solution, the movable shaft 204 is provided to support the movable seat 205, so that the movable seat 205 can rotate on its surface, thereby adjusting the angle of the positioning cover 208, which is convenient for the positioning cover 208 to be sleeved on the surface of the hanging ring 101. The front and back sides of the fixing frame 201 are fixedly connected with elastic blocks 202, and one side of the elastic block 202 is movably connected to the surface of the adjustment plate 203. Through the above technical solution, the adjustment plate 203 is stored through the provision of the fixing frame 201. When the positioning cover 208 is not in use, the adjustment plate 203 can be placed inside the fixing frame 201 to prevent the adjustment The section plate 203 prevents the movement of objects, and the front and back sides of the first fixed seat 210 are movably connected with nuts 211. The inner cavity of the nut 211 is threadedly connected to the surface of the screw 212. Through the above technical solution, the setting of the nut 211 fixes the screw 212, so that after the positioning cover 208 is positioned, the screw 212 is prevented from rotating again, causing the position of the positioning cover 208 to move. The inner cavity of the positioning cover 208 is fixedly connected with a damping pad 207. The damping pad 207 is made of rubber, and the inner side of the damping pad 207 is movably connected to the surface of the hanging ring 101. Through the above technical solution, the setting of the damping pad 207 increases the friction between the inside of the positioning cover 208 and the surface of the hanging ring 101, thereby preventing the surface of the hanging ring 101 from detaching from the inside of the positioning cover 208.
[0028] See also Figure 1 、 Figure 3 and Figure 4, a hook anti-slip assembly of an electric chain hoist, a fixing mechanism 3 is installed on the right side of the positioning cover 208, the fixing mechanism 3 includes a support seat 303 and a second fixing seat 304, the left side of the support seat 303 is fixedly connected to the right side of the hanging ring 101, the left side of the second fixing seat 304 is fixedly connected to the right side of the positioning cover 208, the inner cavity of the support seat 303 is fixedly connected to the support shaft 306, the surface of the support shaft 306 is movably connected to the movable plate 302, the top of the movable plate 302 is fixedly connected to the spring 305, the top of the spring 305 is fixedly connected to the fixing plate 301, and the bottom of the fixing plate 301 is plugged into the inner cavity of the second fixing seat 304, Through the above technical solution, the position of the fixed plate 301 is supported by the setting of the spring 305, so that its position can be adjusted by moving the fixed plate 301, so that it can be plugged into the interior of the second fixed seat 304 to complete the fixation of the position of the positioning cover 208. The top of the movable plate 302 is fixedly connected to the guide rod 307, and the surface of the guide rod 307 is movably connected to the inner cavity of the fixed plate 301. The spring 305 is sleeved on the surface of the guide rod 307. Through the above technical solution, the setting of the guide rod 307 plays a guiding role in the movement of the fixed plate 301, thereby preventing the position of the fixed plate 301 from shifting during the movement.
[0029] The working principle of the present invention is as follows: first, by holding the adjustment plate 203 and rotating it, the screw 212 is driven to rotate inside the first fixed seat 210 by the rotation of the adjustment plate 203, and after the adjustment plate 203 is moved to the top of the hanging ring 101, the positioning seat 209 is driven to rotate by the rotation of the adjustment plate 203, and then by holding the positioning cover 208 and rotating it, the positioning plate 206 is driven to rotate by the rotation of the positioning cover 208, and the movable seat 205 is driven to rotate on the surface of the movable shaft 204 by the rotation of the positioning plate 206, thereby adjusting the angle of the positioning cover 208 until the interior of the positioning cover 208 completely covers the surface of the hanging ring 101. After the hanging ring 101 enters the interior of the positioning cover 208, the inner side of the damping pad 207 will contact the surface of the hanging ring 101, thereby increasing the friction force on the hanging ring 101 inside the positioning cover 208, preventing the hanging ring 101 from detaching from the interior of the positioning cover 208, and then by holding the nut 211 When the first locking nut 211 is in the state of being pressed down, the locking nut 211 is in the state of being pressed down, and the locking nut 211 is in the state of being pressed down, so that the locking nut 211 is in the state of being pressed down, and the locking nut 211 is in the state of being pressed down, so that the locking nut 211 is in the state of being pressed down, and the locking nut 211 is in the state of being pressed down, so that the locking nut 211 is in the state of being pressed down, and the locking nut 211 is in the state of being pressed down,
