[0029] Example 1

[0030] Reference Figures 1-7 This is the first embodiment of the present utility model. This embodiment provides an electric hoist lifting device, which includes a main body component 100 and a fixing component 200. The two work together to close the hook and prevent the item from falling off.

[0031] The main component 100 includes an electric hoist crane 101, with a motor 102 at one end and a wire rope 103 at the bottom.

[0032] The electric hoist crane 101 is a small and lightweight lifting device that uses an electric motor as a power source and drives the hook to lift and move heavy objects via a wire rope 103. The motor 102 is a device that converts electrical energy into mechanical energy and serves as the core power source in the electric hoist crane 101. It drives the reducer, drum, or sprocket to rotate, thereby driving the wire rope 103 to lift and move the hook, completing the lifting and moving of heavy objects. The wire rope 103 is a key component that bears and transmits the lifting force.

[0033] The fixing component 200 is located at the bottom of the wire rope 103 and includes a fixing member 201. The fixing member 201 includes a fixing frame 2011. A fixing shaft 2012 is inserted into the inner wall of the fixing frame 2011. A hook 2013 is sleeved on the outer side of the fixing shaft 2012. Multiple toothed grooves 2013-1 are opened on the inner wall of the hook 2013.

[0034] The fixing frame 2011 is fixed to the bottom of the wire rope 103, and the hook 2013 is a lifting hook.

[0035] The fixing frame 2011 is used to support the fixing shaft 2012. The fixing shaft 2012 is movably connected to the hook 2013. When the hook 2013 needs to be used, the item is placed in the hook 2013. By moving the hook 2013, the toothed groove 2013-1 will move. After the hook 2013 is moved to the desired position, the fixing frame 2011 and the hook 2013 can be engaged, so that the item can be lifted.

[0036] Example 2

[0037] Reference Figures 1-7This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the fixing component 200 also includes a locking component 202, which includes a protective block 2021. The protective block 2021 is fixed to one end of the fixing shaft 2012. A torsion spring 2022 is also sleeved on the outside of the fixing shaft 2012. One end of the torsion spring 2022 is fixed to one end of the protective block 2021, and the other end is fixed to one end of the hook 2013.

[0039] By moving the hook 2013, the hook 2013 will exert a torsional force on the torsion spring 2022. After moving the hook 2013 to the desired position, it can be used.

[0040] Specifically, the inner wall of the tooth groove 2013-1 is provided with teeth 2023, and a pressing rod 2024 is fixed to one end of the teeth 2023.

[0041] By moving the pressing rod 2024, the tooth 2023 moves, which in turn moves the hook 2013. The movement of the hook 2013 applies a torsional force to the torsion spring 2022. After moving the hook 2013 to the desired position, the movement of the pressing rod 2024 is released, causing the tooth 2023 to engage with the tooth groove 2013-1, thus enabling its use.

[0042] Specifically, the inner wall of the extrusion rod 2024 is provided with an extrusion groove 2024-1, and the inner wall of the extrusion groove 2024-1 is provided with an extrusion strip 2025.

[0043] By moving the extrusion rod 2024, the extrusion rod 2024 drives the extrusion groove 2024-1 to move. The movement of the extrusion groove 2024-1 will extrude the extrusion strip 2025. At this time, the hook 2013 can be moved. The movement of the hook 2013 will apply a torsional force to the torsion spring 2022. After the hook 2013 is moved to the desired position, the movement of the extrusion rod 2024 is released. Through the rebound of the extrusion strip 2025, the extrusion rod 2024 can be extruded, causing the teeth 2023 to engage with the tooth groove 2013-1.

[0044] Specifically, one end of the extrusion strip 2025 is provided with a support rod 2026. The extrusion strip 2025 is made of elastic material, and the inner wall of the support rod 2026 is provided with a support groove 2026-1.

[0045] The support rod 2026 is used to support the extrusion strip 2025, and the support rod 2026 is fixed to the fixing frame 2011.

[0046] By moving the extrusion rod 2024, the extrusion rod 2024 drives the extrusion groove 2024-1 to move. The movement of the extrusion groove 2024-1 will extrude the extrusion strip 2025. When the extrusion rod 2024 moves, one end will move on the inner wall of the support groove 2026-1. The support groove 2026-1 is used to provide movement space for one end of the extrusion rod 2024. The movement of the hook 2013 will apply a torsional force to the torsion spring 2022. After the hook 2013 is moved to the desired position, the movement of the extrusion rod 2024 is released. Through the rebound of the extrusion strip 2025, the extrusion rod 2024 can be extruded, causing the teeth 2023 to engage with the tooth groove 2013-1.

[0047] When it is necessary to return the hook 2013 to its original position, the pressing rod 2024 is moved. The pressing rod 2024 moves the pressing groove 2024-1. The movement of the pressing groove 2024-1 will press the pressing strip 2025. The movement of the pressing rod 2024 will cause the teeth 2023 to separate from the tooth groove 2013-1. At this time, the limitation on the hook 2013 is released. Then, the force of the torsion spring 2022 can return the hook 2013 to its original position for the next use.

[0048] Example 3

[0049] Reference Figure 6 and Figure 7 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0050] Specifically, a fixing rod 2027 is fixed to one end of the fixing frame 2011, and a protective plate 2028 is fixed to one end of the fixing rod 2027.

[0051] The fixing rod 2027 is used to support the protective plate 2028, which is used to protect the objects on the inner wall.

[0052] Specifically, the fixing component 200 also includes a limiting member 203, which includes a connecting shaft 2031. The connecting shaft 2031 is inserted into the inner wall of the pressing rod 2024 for fixing, and the other end is set on the inner wall of the fixing frame 2011 for rotation. A support frame 2032 is sleeved on the outside of the connecting shaft 2031, and a locking rod 2033 is provided on the inner wall of the support frame 2032.

[0053] The connecting shaft 2031 is movably connected to the support frame 2032.

[0054] The support frame 2032 is used to support the locking rod 2033, and the other end is fixed to one end of the protective plate 2028. By moving the locking rod 2033, the locking rod 2033 can release the limit on the connecting shaft 2031. After the limit is released, by rotating the connecting shaft 2031, the rotation of the connecting shaft 2031 will drive the pressing rod 2024 to move.

[0055] Specifically, a positioning shaft 2034 is inserted into the inner wall of the locking rod 2033, and a first spring 2035 is sleeved on the outer side of the positioning shaft 2034. One end of the first spring 2035 is fixed to the inner wall of the support frame 2032, and the other end is fixed to the inner wall of the locking rod 2033.

[0056] The positioning shaft 2034 is used to support the locking rod 2033 and is movably connected to it. By moving the locking rod 2033, the locking rod 2033 will compress the first spring 2035, which will release the limit on the connecting shaft 2031 and adjust the hook 2013. After the adjustment is completed, by releasing the locking rod 2033, the force of the rebound of the first spring 2035 will cause the locking rod 2033 to move, which will then re-limit the adjusted hook 2013.

[0057] Specifically, a second spring 2036 is fixed to the bottom of the locking rod 2033, a positioning frame 2037 is sleeved on the outside of the second spring 2036, the other end of the second spring 2036 is fixed to the inner wall of the positioning frame 2037, and the other end of the positioning frame 2037 is fixed to the top of the support frame 2032.

[0058] The positioning frame 2037 is used to support the second spring 2036 and prevent the second spring 2036 from shifting during movement. By pressing one end of the locking rod 2033, the locking rod 2033 moves and presses the second spring 2036. Due to the setting of the positioning shaft 2034, when one end of the locking rod 2033 is pressed, the other end will be lifted. At this time, the limit on the connecting shaft 2031 can be released, and the hook 2013 can be adjusted. After the adjustment is completed, by releasing the locking rod 2033, the force of the rebound of the second spring 2036 and the first spring 2035 will drive the locking rod 2033 back to its original position.

[0059] Specifically, a locking ring 2038 is provided on one side of the locking rod 2033, and a locking groove 2038-1 is provided on the inner wall of the locking ring 2038. The locking rod 2033 is provided on the inner wall of the locking groove 2038-1, and the locking ring 2038 is sleeved on the inner wall of the connecting shaft 2031. A handle 2039 is fixed at one end of the connecting shaft 2031.

[0060] By pressing one end of the locking rod 2033, the locking rod 2033 moves and presses the second spring 2036. Due to the positioning shaft 2034, when one end of the locking rod 2033 is pressed, the other end will be lifted, causing the locking rod 2033 to separate from the locking groove 2038-1. The locking ring 2038 is sleeved on the outside of the connecting shaft 2031. By separating the locking rod 2033 from the locking groove 2038-1, the handle 2039 can be rotated. The rotation of the handle 2039 will drive the connecting shaft 2031 to rotate, causing the hook 2013 to move.

[0061] When using the hook 2013, to prevent the suspended item from falling off, first place the item inside the hook 2013, then press the locking rod 2033. The locking rod 2033 moves, pressing the second spring 2036. The movement of the locking rod 2033 also presses the first spring 2035. The movement of the locking rod 2033 separates it from the locking groove 2038-1. At this point, the handle 2039 can be rotated. The rotation of the handle 2039 drives the connecting shaft 2031 to rotate, which in turn moves the pressing rod 2024. The pressing rod 2024 moves the pressing groove 2024-1, which in turn presses the pressing strip 2025. As the pressing rod 2024 moves... One end will move on the inner wall of the support groove 2026-1, at which time the hook 2013 can be moved. The movement of the hook 2013 will apply a torsional force to the torsion spring 2022. After the hook 2013 is moved to the desired position, the handle 2039 is released. Through the rebound of the pressing bar 2025, the pressing rod 2024 can be pressed, causing the teeth 2023 to engage with the tooth groove 2013-1. After the hook 2013 is moved to the desired position, the engaging rod 2033 is released. At this time, through the rebound of the first spring 2035 and the second spring 2036, the engaging rod 2033 is driven to re-engage with the engaging groove 2038-1, so as to limit the connecting shaft 2031, and thus limit the hook 2013. By closing the hook, the item is prevented from falling off.

[0062] When it is necessary to return the hook 2013 to its original position, the locking rod 2033 is pressed to separate the teeth 2023 from the grooves 2013-1 on the hook 2013. At this time, the force of the torsion spring 2022 can drive the hook 2013 back to its original position for the next use.

[0063] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
