[0024] 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.

[0025] This utility model provides a variable RV roof lifting device, such as Figures 1-6 As shown, the system includes a support frame 1 and a lifting assembly 2. The support frame 1 includes an outer tube 11, an inner tube 12 inside the outer tube 11, and an inner tube 13 inside the inner tube 12. The three tubes—outer tube 11, inner tube 12, and inner tube 13—achieve three levels of variable height through the changing of the clamp holes and the fixing of the pins, thus expanding the application range of RV lifting. The lifting assembly 2 includes a top cover 21, a rotating plate assembly 22, and a lifting adjustment assembly 23. The rotating plate assembly 22 includes a swing end 221 and a positioning end 222. The top cover 21 is installed on the swing end 221. The lifting adjustment assembly 23 includes a lead screw 231. The top of the lead screw 231 is provided with a rotating end 233. A pushing end 232 is installed on the lead screw 231. The upper end of the rotating end 233 is fixed to the top tube 235 by a bearing. The pushing end 232 is connected to the inner tube 13. The positioning end 222 is installed on the top of the top tube 235.

[0026] In this embodiment, the bottom end of the outer tube 11 is hinged to a base 14 to facilitate the support and fixation of the bottom end.

[0027] Specifically, pins 15 are installed on both sides of the top of the outer tube 11, and strip-shaped holes 16 are provided on the side walls of the middle tube 12 and the inner tube 13. Several locking holes 161 are installed at equal intervals on the strip-shaped holes 16, with the diameter of the locking holes 161 being larger than the width of the strip-shaped holes 16. The pins 15 installed on both sides of the top of the outer tube 11 cooperate with the strip-shaped holes 16 and locking holes 161 on the side walls of the middle tube 12 and the inner tube 13, allowing the user to adjust the height of the support frame to three levels by moving the middle tube 12 and the inner tube 13 and fixing them to the locking holes 161 at different positions, according to actual needs. The diameter of the locking holes 161 is larger than the width of the strip-shaped holes 16. This design ensures that the pins 15 can form a firm fixation after being inserted into the locking holes 161, effectively preventing the middle tube 12 and the inner tube 13 from sliding or shifting under external force, thus ensuring the stability and safety of the support frame after height adjustment. The support frame employs a three-layer tube design (outer tube, middle tube, and inner tube), achieving three levels of height adjustment through variations in locking holes and pin fixation. This design allows the RV lifting device to be flexibly adjusted according to actual needs, adapting to different terrains and parking conditions, thus expanding the application range of RV lifting systems. The top cover, rotating plate assembly, and lifting adjustment component work together to form a stable lifting structure. In particular, the screw design in the lifting adjustment component, through the cooperation of the rotating and pushing ends, achieves height adjustment of the inner tube, thereby enabling changes in the height of the entire support frame. This process is simple to operate and easy for users to master.

[0028] Furthermore, the pin 15 includes a fixing sleeve 151, which is installed on the outer wall of the outer tube 11. A manual end 152 is provided inside the fixing sleeve 151. A sliding rod 153 is installed at one end of the manual end 152, and a protrusion 154 is installed at the end of the sliding rod 153. The size of the sliding rod 153 is adapted to the size of the strip hole 16, and the size of the protrusion 154 is adapted to the size of the locking hole 161. When the manual end 152 is pressed inward, the sliding rod 153 contacts the strip hole 16, which facilitates the adjustment of the length of the support frame 1. When adjusted to the position of the locking hole 161, the manual end 152 moves outward, which drives the protrusion 154 to engage with the locking hole 161 to achieve the locking and fixing operation. In order to facilitate the outward movement of the manual end 152, a spring is installed on the inner wall of the fixing sleeve 151. After the manual end 152 is released, the spring action realizes that the manual end 152 pops outward and resets.

[0029] Furthermore, the positioning end 222 has a disc structure, and the surface of the positioning end 222 is provided with several annularly arranged adjustment holes. The middle part of the swing end 221 is rotatably connected to the positioning end 222 through a rotating shaft. Several positioning holes are provided on the swing end 221, and limit handles 223 are installed at the positioning holes. The end of the limit handle 223 passes through the positioning hole and is connected to different adjustment holes, so as to facilitate the angle adjustment of the swing end 221.

[0030] Furthermore, the jacking pipe 235 has a plug-type oil seal port for adding or replacing friction grease to the lifting adjustment component 23. The plug can be opened at any time, which is convenient for maintenance and replacement, and easy to operate. This enhances the performance of the lifting adjustment component 23 and ensures the quality of the jacking device.

[0031] Furthermore, the push end 232 is threadedly connected to the lead screw 231, the rotating end 233 is a horizontal bevel gear, and a vertical bevel gear is provided on the upper side of the rotating end 233. The two bevel gears mesh, and a drive handle 234 is installed on the outside of the vertical bevel gear to facilitate manual turning to adjust the lifting operation of the jacking tube 235.

[0032] When using the variable RV lifting device of this utility model, the user first adjusts the height of the support frame 1 by operating the pin 15 according to actual needs. Specifically, the manual end 152 is pressed inward to make the sliding rod 153 contact the strip hole 16, and then the middle tube 12 and inner tube 13 are moved to the desired position. When the middle tube 12 and inner tube 13 are moved to the appropriate position, the manual end 152 moves outward under the action of the spring, causing the protrusion 154 to engage in the locking hole 161, achieving a firm fixation.

[0033] After the support frame 1 is adjusted to the appropriate height, the user drives the lifting and adjusting assembly 23 by rotating the drive handle 234. The rotation of the drive handle 234 drives the vertical bevel gear to rotate, which in turn drives the horizontal bevel gear (rotating end 233) to rotate through meshing transmission. The rotation of the rotating end 233 drives the lead screw 231 to rotate. Since the pushing end 232 is threadedly connected to the lead screw 231, the pushing end 232 will move up and down along the lead screw 231. The up and down movement of the pushing end 232 will drive the inner tube 13 to move up and down, thereby realizing the lifting or lowering of the entire support frame 1.

[0034] Users can adjust the tilt of the lifting assembly 2 by adjusting the angle of the swing end 221. Specifically, first loosen the limit handle 223, then rotate the swing end 221 to the desired angle. Finally, pass the end of the limit handle 223 through the positioning hole and engage it with the different adjustment holes to securely fix the swing end 221. When it is necessary to add or replace friction grease to the lifting adjustment assembly 23, the user can open the plug-type oil seal on the jacking tube 235. After adding or replacing the friction grease through the oil seal, replace the plug to complete the maintenance and upkeep.
