Description

Technical Field

[0001] This application relates to the field of marine technology, and more particularly to a lifting device, outboard motor, and water-based mobile equipment. Background Technology

[0002] In the shipbuilding industry, the lifting device used needs to be limited by a limiting mechanism when it is lifted into position, and the limiting mechanism needs to be manually unlocked to release the limit when the lifting device is released, resulting in a poor user experience for the entire lifting device. Summary of the Invention

[0003] This application provides a tilting device, including:

[0004] The fixture is provided with a lifting spindle and a sliding groove. The sliding groove includes a sliding section, a limiting section and an unlocking section. The groove depth of the sliding section is less than the groove depth of the limiting section and the groove depth of the limiting section is less than the groove depth of the unlocking section.

[0005] A tilting bracket, which is connected to the tilting main shaft and configured to tilt relative to the clamp, is used to connect to the outboard motor main unit;

[0006] A limiting bracket, comprising a bracket body and a limiting shaft, wherein one end of the bracket body is rotatably connected to the lifting bracket, and the other end is connected to the limiting shaft, the limiting shaft being configured to slide relative to the bracket body in a direction parallel to the lifting main shaft, and the end of the limiting shaft also slidingly engaging with the slide groove;

[0007] Wherein, one end of the limiting section is set as a locking position, and the other end of the limiting section is connected to the unlocking section, so that the limiting shaft can be disengaged from the locking position and enter the unlocking section under the action of a driving force.

[0008] This application embodiment also provides an outboard motor, including an outboard motor main unit and the tilting device, wherein the outboard motor main unit is connected to the tilting bracket.

[0009] This application also provides a water-based mobile device, including a hull and an outboard motor, wherein the outboard motor is movably connected to the hull.

[0010] The lifting device of this application, by setting a groove on the fixture, allows the limiting shaft to slide within the groove, and the end of the limiting shaft can slide relative to the groove along its axial direction. Simultaneously, the groove depth of the sliding section is less than the groove depth of the limiting section. After the limiting shaft enters the limiting section from the sliding section, the end of the limiting shaft moves axially to abut against the limiting section, thus limiting the lifting device. The groove depth of the limiting section is less than the groove depth of the unlocking section. Under the lifting action of a driving force, after the limiting shaft enters the unlocking section from the limiting section, the end of the limiting shaft moves axially to abut against the unlocking section, thus quickly unlocking the lifting device. Therefore, while ensuring rapid limiting and rapid unlocking of the lifting device after lifting, the overall structure of the lifting device is simplified. Attached Figure Description

Furthermore, unless expressly defined herein, terms such as those defined in a general dictionary should be interpreted as having the same meaning as they have in the relevant art and in the content of this application, and will not be interpreted as having an idealized or overly formal meaning.

[0073] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0074] like Figure 1 As shown, this embodiment provides a water-based mobile device 300, including a hull 301 and an outboard motor 200, the outboard motor 200 being movably connected to the hull 301. The outboard motor 200 serves as an auxiliary propulsion unit for the water-based mobile device 300, and its attitude can change relative to the hull 301. When the outboard motor 200 is needed, it can be positioned below the water surface to provide propulsion for the movement of the hull 301. When the outboard motor 200 is not needed, it can be positioned above the water surface to reduce water resistance experienced by the hull 301 during movement.

[0075] like Figure 2 As shown, and with reference Figure 1 This embodiment provides an outboard motor 200, including an outboard motor main unit 201 and a tilting device 100. The tilting device 100 includes a clamp 1 and a tilting bracket 20, with the outboard motor main unit 201 connected to the tilting bracket 20. The clamp 1 is fixed to the hull 301, and the tilting bracket 20 is connected to the clamp 1 and can tilt relative to the clamp 1, so that the outboard motor main unit 201 connected to the tilting bracket 20 can tilt relative to the hull 301. Thus, when the outboard motor 200 is not needed, the tilting bracket 20 tilts to raise the outboard motor main unit 201 above the water surface, and when the outboard motor 200 is needed, the tilting bracket 20 unlocks and releases, causing the outboard motor main unit 201 to fall back below the water surface.

[0076] like Figures 3 to 5As shown, this embodiment provides a tilting device 100, including a clamp 1, a tilting bracket 20, and a limiting bracket 30. The clamp 1 is provided with a tilting main shaft 11 and a sliding groove 12. The sliding groove 12 includes a sliding section 121, a limiting section 122, and an unlocking section 123. The groove depth of the sliding section 121 is less than the groove depth of the limiting section 122, and the groove depth of the limiting section 122 is less than the groove depth of the unlocking section 123. The tilting bracket 20 is connected to the tilting main shaft 11 and configured to tilt relative to the clamp 1. The tilting bracket 20 is used to connect to the outboard motor. The limiting bracket 30 includes a bracket body 31 and a limiting shaft 32. One end of the bracket body 31 is rotatably connected to the tilting bracket 20, and the other end is connected to the limiting shaft 32. The limiting shaft 32 is configured to slide relative to the bracket body 31 in a direction parallel to the tilting main shaft 11. The end of the limiting shaft 32 also slides in cooperation with the sliding groove 12. One end of the limiting section 122 is set as a stop position W1, and the other end of the limiting section 122 is connected to the unlocking section 123, so that the limiting shaft 32 can disengage from the stop position W1 and enter the unlocking section 123 under the action of a driving force.

[0077] like Figures 6 to 7 As shown, and see also Figure 1 and Figure 2 In some implementations, the clamp 1 includes two clamping ears 10, which are spaced apart and opposite to each other. Correspondingly, two sliding grooves 12 are provided, located on opposite sides of the two clamping ears 10. A lifting bracket 20 is at least partially installed between the two clamping ears 10, allowing the two ends of the lifting main shaft 11 to pass through the lifting bracket 20 and be rotatably mounted on the two clamping ears 10. This allows the lifting bracket 20 to rotate around the axis of the lifting main shaft 11 under a driving force, thereby causing the lifting bracket 20 to lift relative to the two clamping ears 10. Simultaneously, the lifting bracket 20 is also connected to the outboard motor 201. When the lifting bracket 20 lifts, it drives the outboard motor 201 to move, causing the outboard motor 201 to assume different postures relative to the hull 301.

[0078] The support body 31 is located between two clamping ears 10, and the support body 31 includes a first end 311 and a second end 312. Limiting shafts 32 are installed on both sides of the first end 311 of the support body 31 near the two clamping ears 10. The limiting shafts 32 are parallel to the axis of the lifting main shaft 11, and the end of the limiting shaft 32 near the slide groove 12 is slidably fitted into the slide groove 12. This not only allows the two clamping ears 10 to support the support body 31 from both sides, but also allows the first end 311 of the support body 31 to move relative to the slide groove 12 via the limiting shaft 32. Specifically, a bushing 321 is provided at the end of the limiting shaft 32 near the slide groove 12. The outer diameter of the bushing 321 is larger than the outer diameter of the limiting shaft 32, and the outer diameter of the bushing 321 is smaller than the minimum groove width of the slide groove 12. The bushing 321 is made of flexible material and abuts against the wall of the slide groove 12, thereby the bushing 321 plays a role in shock absorption and buffering of the movement of the limiting shaft 32 in the slide groove 12.

[0079] The second end 312 of the support body 31 is rotatably connected to the lifting support 20 via a rotating shaft 22. The rotating shaft 22 is parallel to the axis of the lifting main shaft 11, and both ends of the rotating shaft 22 are fixed to opposite sides of the lifting support 20, so that the rotating shaft 22 is fixed relative to the lifting support 20. The second end 312 of the support body 31 is provided with a through hole 3120 for the rotating shaft 22 to pass through, so that the second end 312 of the support body 31 is rotatably mounted on the rotating shaft 22, so that the second end 312 of the support body 31 can rotate around the axis of the rotating shaft 22.

[0080] Specifically, the lifting bracket 20 is provided with an ear plate 21, which has a through hole 210 for the rotating shaft 22 to pass through. The ear plate 21 is located approximately at the middle position of the rotating shaft 22, and a torsion spring 23 is fitted at the middle position of the rotating shaft 22.

[0081] The torsion spring 23 provides a force to the support body 31 relative to the lifting bracket 20, causing the support body 31 to open relative to the lifting bracket 20 under the tension of the torsion spring 23. That is, the opening direction of the support body 31 relative to the rotation shaft 22 is opposite to the rotation direction of the lifting bracket 20 relative to the rotation shaft 22. This forces the limiting shaft 32 to also open relative to the lifting bracket 20 as the support body 31 opens. As a result, the limiting shaft 32 always has a tendency to abut against the outside when the lifting bracket 20 is lifted or released, so that the outer peripheral surface of the limiting shaft 32 slides against the inner wall of the slide groove 12. The inner wall of the slide groove 12 guides the sliding of the limiting shaft 32.

[0082] Thus, when the lifting bracket 20 is lifted under the action of a driving force, which can be provided by a power device or human power and applied to the lifting bracket 20, the lifting bracket 20 can be lifted relative to the hull. The driving force mentioned in the following description is the same as the driving force described here. The lifting bracket 20 drives the bracket body 31 to move with the lifting bracket 20 through the rotating shaft 22 fixedly connected to it. At this time, the limiting shaft 32 provided on the first end 311 of the bracket body 31 is limited by the limiting effect of the slide groove 12 and moves approximately along a fixed trajectory, causing the second end 312 of the bracket body 31 to rotate around the axis of the rotating shaft 22, thereby causing the bracket body 31 to change its attitude relative to the lifting bracket 20. During the attitude change of the bracket body 31 relative to the lifting bracket 20, the bracket body 31 can limit the lifting angle of the lifting bracket 20, making the lifting process of the lifting bracket 20 smoother. The lifting angle of the lifting bracket 20 is the angle by which the lifting bracket 20 rotates from its position against the clamp 1 around the rotating shaft 22 to its position separated from the clamp 1. Simultaneously, when the lifting bracket 20 is lifted under a driving force, the lifting bracket 20 drives the bracket body 31 to move along with it via the rotating shaft 22, which is fixedly connected to it. This causes the limiting shaft 32 to move within the slide groove 12 towards the lifting direction of the lifting bracket 20 until it abuts against the inner wall of the slide groove 12. As the lifting bracket 20 continues to lift, the limiting shaft 32 slides upwards against the inner wall of the slide groove 12. The inner wall of the slide groove 12 directly guides the sliding of the limiting shaft 32.

[0083] When the lifting bracket 20 is released and falls back under its own gravity, the bracket body 31 also falls back under its own gravity, causing the limiting shaft 32 to move within the slide groove 12 in the direction of the lifting bracket 20's fall until it abuts against the inner wall of the slide groove 12. As the bracket body 31 continues to fall, the limiting shaft 32 remains pressed against the inner wall of the slide groove 12 and slides downwards. The inner wall of the slide groove 12 directly guides the sliding of the limiting shaft 32.

[0084] like Figures 8 to 9As shown, in some implementation methods, the limiting section 122 is inclined, one end of the limiting section 122 is connected to the sliding section 121, and the other end of the limiting section 122 is set as a locking position W1, which is a locking groove that is recessed away from the sliding section 121. When the lifting device 100 lifts under the action of a driving force, the lifting device 100 causes the limiting shaft 32 to enter the limiting section 122 from the sliding section 121. Since the groove depth of the sliding section 121 is less than the groove depth of the limiting section 122, the end of the limiting shaft 32 moves axially toward the bottom of the sliding groove 12. The end of the limiting shaft 32 always abuts against the bottom of the sliding groove 12, preventing the limiting shaft 32 from moving from the limiting section 122 to the sliding section 121. Thus, after the driving force is removed, the lifting device 100 moves the limiting shaft 32 along the limiting section 122 to the locking position W1 under its own gravity and locks, so that the lifting device 100 can still maintain the lifting state after the load is released.

[0085] It is worth noting that both the sliding section 121 and the limiting section 122 are partial sections of the slide groove 12. The slide groove 12 is a groove formed by slotting inward from the side of the clamping ear 10 facing the limiting shaft 32. The groove depth of the slide groove 12 refers to the vertical distance from the side of the clamping ear 10 facing the limiting shaft 32 to the bottom of the slide groove 12. Correspondingly, the groove depth of the sliding section 121 is the vertical distance from the side of the clamping ear 10 facing the limiting shaft 32 to the bottom of the slide groove 12 corresponding to the sliding section 121, and the groove depth of the limiting section 122 is the vertical distance from the side of the clamping ear 10 facing the limiting shaft 32 to the bottom of the slide groove 12 corresponding to the limiting section 122.

[0086] Simultaneously, the unlocking section 123 is connected to the higher end of the limiting section 122. When the lifting device 100 needs to unlock, it continues to lift under the action of a driving force, causing the limiting shaft 32 to disengage from the stop position W1 and move to the unlocking section 123. Since the groove depth of the limiting section 122 is less than that of the unlocking section 123, the end of the limiting shaft 32 moves axially toward the bottom of the slide groove 12. The end of the limiting shaft 32 always abuts against the bottom of the slide groove 12, preventing the limiting shaft 32 from moving from the unlocking section 123 to the limiting section 122. The limiting shaft 32 then strikes the bottom of the groove in the unlocking section 123, producing a striking sound, thus alerting the outside world that the unlocking action has been completed. After the unlocking action is completed, the driving force is removed, and the lifting device 100, under its own gravity, moves the limiting shaft 32 from the unlocking section 123 to the sliding section 121, and then continues to slide down along the sliding section 121 to complete the release action.

[0087] It is worth noting that the unlocking section 123 is a part of the slide groove 12. As mentioned above, the groove depth of the unlocking section 123 is the vertical distance from the side of the clamping ear 10 facing the limiting shaft 32 to the bottom of the slide groove 12 corresponding to the unlocking section 123.

[0088] In summary, the lifting device 100 of this application provides a groove 12 on the clamping ear 10, so that the limiting shaft 32 is slidably fitted in the groove 12, and the end of the limiting shaft 32 can slide relative to the groove 12 along its axial direction. Meanwhile, the groove depth of the sliding section 121 is less than the groove depth of the limiting section 122. After the limiting shaft 32 enters the limiting section 122 from the sliding section 121, the end of the limiting shaft 32 moves axially to the bottom of the limiting section 122, thus limiting the lifting device 100. The groove depth of the limiting section 122 is less than the groove depth of the unlocking section 123. After the limiting shaft 32 enters the unlocking section 123 from the limiting section 122 under the lifting action of a driving force, the end of the limiting shaft 32 moves axially to the bottom of the unlocking section 123, thus quickly unlocking the lifting device 100. It is only necessary to slightly lift the lifting device 100 to unlock it, without the need to set an additional unlocking switch to release the lifting device 100.

[0089] Please combine Figure 7 The limiting bracket 30 also includes an elastic element 322, which is elastically connected between the limiting shaft 32 and the bracket body 31, and is used to drive the end face of the limiting shaft 32 to abut against the bottom wall of the slide groove 12. In one embodiment, the first end 311 of the bracket body 31 has two extending protrusions 313 on both sides, and the extending protrusions 313 extend from the first end 311 of the bracket body 31 away from the second end 312 of the bracket body 31. The extending protrusions 313 have mounting holes 3130, and the limiting shaft 32 is partially received in the mounting holes 3130. The end of the limiting shaft 32 away from the slide groove 12 is provided with a support plate 323 and an elastic element 322, and the support plate 323 is fixed to the end of the limiting shaft 32 away from the slide groove 12. The elastic element 322 is sleeved on the outer periphery of the limiting shaft 32, with one end connected to the bracket body 31 and the other end elastically abutting against and connected to the support plate 323. It applies an elastic force along the axial direction to the limiting shaft 32, causing the limiting shaft 32 to elastically return to its axial position towards the bottom of the slide groove 12. It is worth noting that the elastic element 322 can be a rectangular spring, etc.

[0090] Please combine Figure 7 , Figure 8 and Figure 9The limiting section 122 is connected to the unlocking section 123, and a first support surface P1 is provided between the limiting section 122 and the unlocking section 123. The first support surface P1 is used to prevent the limiting shaft 32 from entering the limiting section 122 from the unlocking section 123. In one embodiment, since the groove depth of the limiting section 122 is less than the groove depth of the unlocking section 123, a stepped surface is formed at the connection between the limiting section 122 and the unlocking section 123, and this stepped surface is the first support surface P1. The first support surface P1 is set approximately perpendicular to the bottom wall of the unlocking section 123, that is, the first support surface P1 is approximately parallel to the axial direction of the limiting shaft 32. Under the action of a driving force, the limiting shaft 32 slides from the limiting section 122 to the bottom wall of the unlocking section 123 along the axial direction under the action of the elastic force provided by the elastic element 322, so that the limiting shaft 32 is resisted by the first support surface P1 and cannot fall back to the limiting section 122 after the driving force is removed.

[0091] Please combine Figure 7 , Figure 8 and Figure 9 The unlocking section 123 includes a guide ramp P4, which connects the unlocking section 123 and the sliding section 121. The guide ramp P4 guides the limiting shaft 32 from the unlocking section 123 into the sliding section 121. In one embodiment, the guide ramp P4 extends obliquely outward from the unlocking section 123 to the sliding section 121. The guide ramp P4 is set as a plane or a curved surface, so that when the limiting shaft 32, which has moved to the unlocking section 123, slides down under the gravity of the lifting device 100, the guide ramp P4 guides the limiting shaft 32 to move quickly from the unlocking section 123 to the sliding section 121, thereby realizing the rapid release and subsequent fall of the lifting device 100.

[0092] The guide slope P4 intersects with the first support surface P1, ensuring that after the limiting shaft 32 moves past the first support surface P1, it moves directly to contact the guide slope P4, and the guide slope P4 quickly guides the limiting shaft 32 to slide down.

[0093] Please combine Figure 7 , Figure 8 and Figure 9The sliding section 121 is connected to the limiting section 122, and a second support surface P2 is provided between the sliding section 121 and the limiting section 122. The second support surface P2 is used to prevent the limiting shaft 32 from entering the sliding section 121 from the limiting section 122. In one embodiment, since the groove depth of the limiting section 122 is greater than the groove depth of the sliding section 121, a stepped surface is formed at the connection between the limiting section 122 and the sliding section 121, which is the second support surface P2. The second support surface P2 is set approximately perpendicular to the bottom wall of the limiting section 122. Under the action of a driving force, the limiting shaft 32 slides from the sliding section 121 to the second support surface P2. Under the action of the elastic force provided by the elastic element 322, the limiting shaft 32 slides axially toward the bottom wall of the limiting section 122, so that the limiting shaft 32 is resisted by the second support surface P2 and cannot fall back to the sliding section 121 after the driving force is removed.

[0094] Please combine Figure 7 , Figure 8 and Figure 9 A third support surface P3 is provided at the end of the limiting section 122 away from the unlocking section 123. When the limiting shaft 32 is locked in the limiting section 122, the third support surface P3 abuts against the outer peripheral surface of the limiting shaft 32. In one embodiment, the location of the third support surface P3 is designated as the locking position W1. The third support surface P3 is arranged in an arc shape and is adapted to the shape of the bushing 321 of the limiting shaft 32, so that when the limiting shaft 32 moves to the point where the outer peripheral surface of the bushing 321 abuts against the third support surface P3, the limiting shaft 32 can be locked precisely at the locking position W1, preventing the limiting shaft 32 from disengaging from the locking position W1 or wobbling within the locking position W1 under the action of external force.

[0095] Furthermore, the third support surface P3 intersects with the second support surface P2, and the third support surface P3 is smoothly connected to the second support surface P2, so that the limiting shaft 32 can slide along the second support surface P2 to abut against the third support surface P3 after the driving force is removed, and lock at the stop position W1.

[0096] Specifically, the third support surface P3 is set approximately perpendicular to the bottom wall of the limiting section 122 so that the extension direction of the third support surface P3 is the same as the axial direction of the limiting shaft 32, thereby increasing the contact area between the third support surface P3 and the limiting shaft 32 and improving the stability of the limiting shaft 32 at the locking position W1.

[0097] Please combine Figure 7 , Figure 8 and Figure 9A first transition wall P5 is provided on the side of the limiting section 122 away from the sliding section 121, and a second transition wall P6 is provided on the side of the unlocking section 123 away from the sliding section 121. The first transition wall P5 and the second transition wall P6 are connected to guide the limiting shaft 32 from the limiting section 122 to the unlocking section 123. In one embodiment, the first transition wall P5 is disposed opposite to the second support surface P2, and one end of the first transition wall P5 is smoothly connected to the third support surface P3. The second transition wall P6 is disposed opposite to the guide slope P4, and the second transition wall P6 is smoothly connected to the end of the first transition wall P5 away from the third support surface P3, so that the third support surface P3, the first transition wall P5 and the second transition wall P6 are connected end to end in sequence, thereby guiding the limiting shaft 32 to move along a preset path when the lifting device 100 is unlocked, thereby realizing the unlocking of the lifting device 100.

[0098] Specifically, the first transition wall P5 and the second transition wall P6 are coplanar, and the limiting shaft 32 can move smoothly from the first transition wall P5 to the second transition wall P6, which can improve the stability of the limiting shaft 32 when it enters the unlocking section 123 from the limiting section 122.

[0099] Thus, when the lifting device 100 is unlocked, the limiting shaft 32 is disengaged from the third support surface P3 under the action of a driving force and slides close to the first transition wall P5 toward the unlocking section 123. Since the first transition wall P5 and the second transition wall P6 are smoothly connected, the limiting shaft 32 can be guided to move close to the first transition wall P5 and the second transition wall P6 to the unlocking section 123, thereby realizing the unlocking of the lifting device 100.

[0100] Please combine Figure 8 and Figure 9 And see Figure 7 The sliding section 121 includes a first sidewall P7. When the limiting shaft 32 moves within the sliding section 121 toward the limiting section 122, the first sidewall P7 abuts against the outer peripheral surface of the limiting shaft 32, guiding the limiting shaft 32 to move within the sliding section 121 toward the limiting section 122. In one embodiment, the trajectory of the sliding section 121 is approximately inclined, and the higher end of the sliding section 121 is located on the side of the lower end of the sliding section 121 closer to the rotation shaft 22, so that the sliding section 121 is inclined from bottom to top toward the position of the rotation shaft 22.

[0101] The first sidewall P7 is the inner sidewall of the sliding section 121. The first sidewall P7 is arranged along the extension direction of the sliding section 121 and is located on the side of the sliding section 121 away from the rotation axis 22. Thus, when the lifting device 100 lifts, the second end 312 of the support body 31 rotates upward around the rotation axis 22, causing the first end 311 of the support body 31 to move upward relative to the rotation axis 22. Under the tension of the torsion spring 23 installed on the rotation axis 22, the support body 31 also opens relative to the lifting support 20, forcing the limiting shaft 32 to also open relative to the lifting support 20 as the support body 31 opens. That is, the opening direction of the support body 31 relative to the rotation axis 22 is opposite to the rotation direction of the lifting support 20 relative to the rotation axis 22, so that the limiting shaft 32 always has a tendency to abut outward. Under this tendency, the limiting shaft 32 moves toward the first sidewall P7 until the limiting shaft 32 abuts against the first sidewall P7. The lifting device 100 continues to lift, and the first end 311 of the support body 31 continues to move upward relative to the rotating shaft 22. The limiting shaft 32 slides upward close to the first side wall P7 in the sliding section 121, and the first side wall P7 acts as a stop for the limiting shaft 32, ensuring the stability of the lifting device 100 when it lifts and preventing it from shaking.

[0102] Please combine Figure 8 and Figure 9 And see Figure 7The sliding section 121 includes a second sidewall P8. When the limiting shaft 32 moves away from the unlocking section 123 within the sliding section 121, the second sidewall P8 abuts against the outer peripheral surface of the limiting shaft 32, guiding the limiting shaft 32 to move away from the unlocking section 123 within the sliding section 121. In one embodiment, the second sidewall P8 is the inner sidewall of the sliding section 121 and is disposed opposite to the first sidewall P7. The second sidewall P8 is disposed along the extending direction of the sliding section 121 and is located on the side of the sliding section 121 closest to the rotating shaft 22. Thus, when the lifting device 100 is released, the second end 312 of the support body 31 rotates downward around the rotating shaft 22, causing the first end 311 of the support body 31 to move downward relative to the rotating shaft 22. Under the tension of the torsion spring 23 installed on the rotating shaft 22, the support body 31 also opens relative to the lifting bracket 20, forcing the limiting shaft 32 to also open relative to the lifting bracket 20 as the support body 31 opens. That is, the opening direction of the support body 31 relative to the rotating shaft 22 is opposite to the rotation direction of the lifting bracket 20 relative to the rotating shaft 22, so that the limiting shaft 32 always has a tendency to abut outward. Under this tendency, the limiting shaft 32 moves toward the second side wall P8 until the limiting shaft 32 abuts against the second side wall P8. The lifting device 100 continues to fall under its own gravity, and the first end 311 of the support body 31 continues to move downward relative to the rotating shaft 22. The limiting shaft 32 slides downward close to the second side wall P8 in the sliding section 121, and the second side wall P8 acts as a stop for the limiting shaft 32, ensuring the stability of the lifting device 100 when it is released and preventing it from shaking.

[0103] Please combine Figure 10 and Figure 11 The lifting device 100 also includes a lifting power assembly 40, which is connected to the clamp 1 and the lifting bracket 20, and is used to provide power for the lifting bracket 20 to lift relative to the clamp 1. In one embodiment, a mounting base 13 is also provided between the two clamping ears 10, and the mounting base 13 is connected to the end of the clamping ear 10 away from the lifting main shaft 11. One end of the lifting power assembly 40 is mounted on the mounting base 13, and the other end is connected to the lifting bracket 20, for providing a driving force to lift the lifting bracket 20 around the lifting main shaft 11.

[0104] Further, the lifting power assembly 40 includes a lifting base shaft 43, a telescopic mechanism 41, and an actuator 42. The lifting base shaft 43 is rotatably disposed on the clamp 1 away from the lifting main shaft 11. One end of the telescopic mechanism 41 is connected to the lifting base shaft 43, and the other end is rotatably abutted against the lifting bracket 20. The actuator 42 is connected to the telescopic mechanism 41 and is used to drive the telescopic mechanism 41 to extend or retract. In one embodiment, the lifting base shaft 43 and the lifting main shaft 11 have the same axial direction, and one end of the lifting base shaft 43 passes through the mounting base 13 and is rotatably connected to a clamp 10. The other end of the lifting base shaft 43 is rotatably installed in the mounting base 13. The end of the telescopic mechanism 41 away from the lifting main shaft 11 allows the lifting base shaft 43 to pass through, so that the telescopic mechanism 41 can rotate around the axis of the lifting base shaft 43. When the lifting bracket 20 is lifted, the telescopic mechanism 41 can move synchronously, so that the telescopic mechanism 41 always maintains its abutting effect on the lifting bracket 20.

[0105] The telescopic mechanism 41 includes a cylinder 411 and a telescopic rod 412, which is telescopically installed inside the cylinder 411. The end of the telescopic rod 412 near the lifting main shaft 11 is located outside the cylinder 411, and a connecting sleeve 413 for mounting a connecting shaft 44 is provided at this end. The connecting shaft 44 is rotatably housed within the connecting sleeve 413. The connecting shaft 44 is aligned with the axis of the lifting main shaft 11, and both ends of the connecting shaft 44 pass through the connecting sleeve 413. One end of the connecting shaft 44 is mounted on the ear plate 21, and the other end is mounted on the lifting bracket 20. When the telescopic mechanism 41 drives the lifting bracket 20 to lift, the telescopic mechanism 41 can rotate around the axis of the connecting shaft 44, thereby deflecting the telescopic mechanism 41 relative to the lifting bracket 20 to coordinate with the lifting action of the lifting bracket 20.

[0106] The actuator 42 is installed on the outside of the telescopic mechanism 41 and can move synchronously with the telescopic mechanism 41. The actuator 42 is used to adjust the telescopic rod 412's extension and retraction amount, thereby adjusting the lifting height of the lifting bracket 20 that is lifted by the telescopic rod 412.

[0107] In particular, in another embodiment, the driving force can also be provided by human power, and the lifting bracket 20 is driven to move by human power pushing and pulling.

[0108] Please combine Figure 11The telescopic mechanism 41 is configured as a hydraulic telescopic mechanism, and the actuator 42 is configured as an oil pump motor. The oil pump motor is used to adjust the amount of oil in the hydraulic telescopic mechanism to adjust the telescopic length of the hydraulic telescopic mechanism. In one embodiment, the telescopic mechanism 41 is hydraulically driven, which provides better stability during operation and ensures that the lifting device 100 is not prone to shaking during the lifting process. The actuator 42 is connected to the telescopic mechanism 41 by pipeline and can exchange hydraulic oil with the telescopic mechanism 41. Thus, the actuator 42 controls the amount of oil in the cylinder 411 of the telescopic mechanism 41 to adjust the telescopic distance of the telescopic rod 412 of the telescopic mechanism 41.

All such changes and substitutions fall within the scope defined by this application.
