[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] This utility model provides a lifting variable outrigger, such as Figures 1-4As shown, the system includes a lower shell 1 and an upper shell 2. A top plate 3 is installed on the top of the upper shell 2, and a base 4 is installed at the bottom of the lower shell 1. A locking component 5 is installed on one side of the base 4. An adjustment component 6 is installed on the inner side of the lower shell 1. An inner tube 11 is provided on the inner side of both the lower shell 1 and the upper shell 2. A strip hole 12 is provided on the outer wall of the inner tube 11. A locking hole 121 is provided in the middle and at both ends of the strip hole 12. A pin 21 is installed on the outer side of the upper shell 2. A locking head is installed on the inner end of the pin 21, and the locking head engages with the locking hole 121. A height-adjustable inner tube 11 is provided between the lower shell 1 and the upper shell 2. The strip hole 12 and the locking hole 121 on the outer wall of the inner tube 11 engage with the pin 21 and its locking head on the outer side of the upper shell 2. This design allows the user to quickly adjust the height of the outriggers by simply operating the pin 21, and ensures the stability after adjustment. Meanwhile, locking holes 121 are provided in the middle and at both ends of the strip hole 12, which not only increases the adjustment range, but also allows the outriggers to be securely locked at different height positions, meeting a variety of support needs.
[0028] Furthermore, the introduction of locking component 5 further enhances the stability and safety of the outriggers. When the user needs to secure the outriggers, a simple operation using locking component 5 is all that's needed to firmly lock them in place, effectively preventing the outriggers from shaking or loosening due to external forces during use, thus ensuring the stability and reliability of the support.
[0029] In this embodiment, the top of the upper shell 2 is rotatably connected to the top plate 3 via a bearing, and a fixed shaft 42 is installed on the inner side of the base 4, which is rotatably connected to the bottom of the lower shell 1. This design allows the upper shell 2 to rotate flexibly relative to the top plate 3 and the lower shell 1 to rotate flexibly relative to the base 4, thus giving the outriggers multi-angle adjustment capabilities in both horizontal and vertical directions. This rotatable connection not only enhances the adaptability of the outriggers, enabling them to easily cope with different terrains and support angle requirements, but also improves the flexibility and convenience of the outriggers during use.
[0030] Specifically, a guide shaft 41 is installed on one outer wall of the base 4, and the locking assembly 5 includes a handle ring 51. A guide hole is provided on the outer wall of the handle ring 51, and the guide shaft 41 slides into the guide hole. Through the sliding engagement of the guide shaft 41 with the guide hole on the handle ring 51, stable and smooth movement of the locking assembly 5 on the base 4 is achieved. This design not only makes the locking operation more accurate and reliable but also improves the overall stability of the outriggers, effectively preventing outrigger wobbling caused by loosening of the locking assembly during use.
[0031] Furthermore, a sleeve 52 is installed on the side of the handle 51 near the base 4. A limit rod 53 is slidably installed inside the sleeve 52. One end of the limit rod 53 penetrates the outer wall of the base 4 and engages with the positioning hole 71 on the positioning turntable 7. The end of the limit rod 53 is locked at the outer walls of both sides of the lower shell 1. The engagement of the limit rod 53 with the positioning hole 71 on the positioning turntable 7, and the locking effect of the end of the limit rod 53 on the outer walls of both sides of the lower shell 1, together constitute a stable locking mechanism for the outrigger. This design not only improves the stability of the outrigger during use, but also makes the locking operation simpler and faster, effectively enhancing the user experience.
[0032] Furthermore, a pull ring 54 is installed at the end of the limiting rod 53 furthest from the base 4. The introduction of the pull ring 54 makes it easier for users to pull the limiting rod 53 to lock or unlock. This user-friendly design not only improves the ease of operation of the outriggers but also makes the operation easier and less strenuous for users.
[0033] Furthermore, the pin 21 includes an outer sleeve, inside which a button is slidably mounted. A return spring is installed on the outer wall of the button, and one end of the button is connected to a locking head. When the button is pressed, the locking head disengages from the locking hole 121, allowing the pin 21 to slide into the slot 12. This design of the pin 21 enables quick adjustment and locking of the outrigger height. By pressing the button to disengage the locking head from the locking hole 121, the user can easily slide the pin 21 in the slot 12 to adjust the outrigger height. The presence of the return spring ensures that the locking head automatically resets and engages with the nearest locking hole 121 after the button is released, achieving a stable lock of the outrigger height.
[0034] Furthermore, the adjustment component 6 includes a lead screw assembly, which drives the inner tube 11 to rise and fall. A bevel gear drive assembly is mounted at the bottom of the lead screw assembly, and a rotary handle is mounted on the outer side of the bevel gear drive assembly. The design of the adjustment component 6 enables precise adjustment of the outrigger height. By rotating the rotary handle, the bevel gear is driven to rotate, which in turn drives the lead screw assembly to raise and lower the inner tube 11, allowing the user to precisely control the outrigger height. This design not only improves the adjustment accuracy of the outrigger but also makes the adjustment process smoother and more reliable.
[0035] Furthermore, a protruding plate is installed on the outer bottom of the upper shell 2, which facilitates the operator to adjust the upper shell 2 by hand.
[0036] When using the adjustable outrigger of this invention, to adjust the outrigger height, the user first presses the button on the pin 21. After the button is pressed, the latch head connected to it retracts inward, disengaging from the currently engaged latch hole 121. Next, the user slides the pin 21 along the slot 12 to the desired height. Since the slot 12 has latch holes 121 in the middle and at both ends, the user can select an appropriate height according to actual needs. Once the pin 21 reaches the target position, the button is released. At this time, the return spring pushes the button and latch head back to their original positions, causing the latch head to engage with the nearest latch hole 121, thus achieving a stable lock on the outrigger height.
[0037] The top of the upper shell 2 of the outrigger is rotatably connected to the top plate 3 via a bearing, while the bottom of the lower shell 1 is rotatably connected to the base 4 via a fixed shaft 42. This design allows the outrigger to be adjusted at multiple angles in both the horizontal and vertical directions. Users can adjust the angle of the outrigger by manually rotating the upper shell 2 or the base 4 to meet the needs of different terrains and support angles.
[0038] After adjusting the height and angle of the outriggers, the user needs to perform a locking operation to ensure the stability of the outriggers during use. The user first pulls the limiting rod 53 using the pull ring 54, disengaging it from the positioning hole 71 on the positioning turntable 7. At this time, the user can slide the handle ring 51 along the guide shaft 41, thereby moving the sleeve 52 and the limiting rod 53. Once the handle ring 51 is in the appropriate position, the user pushes the limiting rod 53 again, causing it to pass through the outer wall of the base 4 and engage with the positioning hole 71 on the positioning turntable 7. Simultaneously, the end of the limiting rod 53 will also be locked against the two outer walls of the lower shell 1, thus achieving a stable locking of the outriggers.
[0039] If more precise adjustments to the outrigger height are required, the user can achieve this by rotating the handle on the adjustment assembly 6. Rotating the handle drives the bevel gear, which in turn raises and lowers the inner tube 11 via the lead screw assembly. Because the lead screw assembly has a precise transmission ratio, the user can accurately control the raising and lowering height of the inner tube 11 by rotating the handle, thus achieving fine-tuning of the outrigger height.
[0040] The protruding plate installed on the outer bottom of the upper shell 2 provides a convenient gripping point for the operator. When height adjustment is required, the operator can hold the protruding plate and move the upper shell 2 to raise or lower it, further improving the ease of operation of the outriggers.
