[0027] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0028] like Figures 1 to 7As shown, this utility model provides a self-priming roller lifting frame, including a base 1, two symmetrically arranged mounting brackets 2 on the top of the base 1, a lifting device 7 mounted on the base 1 between the two mounting brackets 2, the lifting device 7 being slidable along the length of the base 1, and the lifting device 7 employing a multi-section electric telescopic rod; a telescopic rod 3 is rotatably mounted between the two mounting brackets 2, the upper end of the lifting device 7 being hinged to the tail end of the telescopic rod 3; a roller 4 is provided at the head end of the telescopic rod 3, the roller 4 being wrapped with absorbent fabric to facilitate wall painting, and an installation tube 41 is fixedly connected between the roller 4 and the telescopic rod 3; four symmetrically arranged pulleys 6 are installed below the base 1, the pulleys 6 sliding along the left and right direction of the base 1, a motor corresponding to the pulleys 6 is provided below the base 1, the output end of the motor being connected to the rotating shaft of the pulleys 6, and a power source is provided inside the base 1 and electrically connected to the motor.

[0029] A liquid storage tank 5 is installed at the upper front end of the base 1. The liquid storage tank 5 is connected to the installation pipe 41 through a liquid-conducting hose 42. A pump body connected to the liquid-conducting hose 42 is installed inside the liquid storage tank 5. An outlet hole is opened at the part of the installation pipe 41 that connects to the roller 4. The installation pipe 41 sprays the liquid inside the liquid storage tank 5 onto the roller 4 through the liquid-conducting hose 42.

[0030] In the above scheme, the roller 4 on the telescopic rod 3 swings up and down through the lifting device 7. During the swinging process, the telescopic rod 3 will automatically adjust according to the distance between the roller 4 and the wall to ensure that the roller 4 is always in contact with the wall, thereby realizing the effect of the roller 4 automatically moving from the upper part of the wall to the lower part, which effectively improves the painting efficiency of the roller 4 on the wall.

[0031] In order to make the position of the lifting device 7 change with the tilt angle of the telescopic rod 3, in this embodiment, a drive unit is provided between the lifting device 7 and the base 1. The drive unit includes a lead screw 13 and a driver 11. A slide groove 12 is provided on the upper part of the base 1 along the length direction of the base 1. The lead screw 13 is rotatably installed in the slide groove 12. The driver 11 is installed on the left side of the base 1. The driver 11 is a motor. The drive end of the driver 11 passes through the base 1 and is connected to the lead screw 13.

[0032] The lifting device 7 on the drive sliding seat 14 is moved so that the lifting device 7 can slide to follow the swing position of the telescopic rod 3, thus preventing the telescopic rod 3 from being unable to swing because the lifting device 7 cannot move horizontally.

[0033] The telescopic rod 3 includes a sleeve 31 and a sliding rod 32. The sliding rod 32 is slidably disposed inside the sleeve 31. The mounting tube 41 is fixed to the front end of the sliding rod 32. The rear end of the sleeve 31 is provided with a hinge seat 311. Both sides of the telescopic end of the lifting device 7 are provided with hinge rods, which are mounted on the hinge seats 311. Both sides of the front end of the sleeve 31 are provided with support shafts 33. The outer ends of the support shafts 33 are rotatably disposed on the mounting frame 2. When the telescopic end of the lifting device 7 rises or falls, the lifting device 7 rotates between the lifting device 7 and the sleeve 31 through the support shafts 33 and the hinge seats 311.

[0034] like Figure 4 , Figure 6 and Figure 7 As shown, in order to enable the sliding rod 32 to automatically slide out of the sleeve 31 and adjust the distance between the roller 4 and the wall, in this embodiment, a disc 321 is rotatably connected to the rear end of the sliding rod 32. A first elastic element 36 is provided between the disc 321 and the inner cavity of the sleeve 31. The first elastic element 36 is a spring, which can push the sliding rod 32, so that the roller 4 always keeps in contact with the wall. An annular washer 361 is connected to the upper end of the first elastic element 36. The annular washer 361 fits against the disc 321. During the sliding process within the sleeve 31, the annular gasket 361 rotates between the disc 321 to reduce wear between the first elastic element 36 and the disc 321; the disc 321 is provided with a guide block 323 in the circumference, and the sleeve 31 is provided with a threaded groove 313 that is adapted to the guide block 323 inside; the front end of the sleeve 31 has a rectangular hole 314, and the sliding rod 32 is located in the rectangular hole 314 and is adapted to the rectangular hole 314. The rectangular hole 314 can limit the position of the sliding rod 32 and prevent the sliding rod 32 from rotating with the disc 321.

[0035] In the above scheme, after the roller 4 contacts the upper or lower part of the wall, the telescopic rod 3 is in its longest state. As the roller 4 moves from top to bottom or from bottom to top, since the distance between the base 1 and the wall remains unchanged, the telescopic rod 3 will gradually shorten or lengthen within the spatial distance between the wall and the base 1. The sliding rod 32 will enter or extend into the sleeve 31 and drive the disc 321 to slide up and down within the sleeve 31. When the disc 321 moves into the sleeve 31, it compresses the first elastic element 36. Since the guide block 323 on the disc 321 is located within the threaded groove 313, when the sliding rod 32 enters or extends into the sleeve 31, the guide block 323 can only move according to the preset position of the threaded groove 313, thus achieving the effect of the sliding rod 32 slowly moving out of the sleeve 31 and preventing the sliding rod 32 from popping out quickly after the first elastic element 36 resets.

[0036] like Figure 4 , Figure 5 and Figure 7As shown, in order to maintain the retracted state after the telescopic rod 3 is retracted as a whole and reduce the space occupied by the telescopic rod 3, in this embodiment, a positioning unit is provided at the rear end of the sleeve 31. The positioning unit includes a guide sleeve 34, which is fixed inside the sleeve 31 and coaxially arranged with the sleeve 31. The sleeve 31 and the guide sleeve 34 are combined to form a slide 312 arranged along the axial direction of the sleeve 31. Through holes 342 are provided on both sides of the upper end of the guide sleeve 34, and a top bead 341 is provided inside the through hole 342. A bottom center of the disc 321 is provided with a... The stepped groove 322 corresponding to the guide sleeve 34 is arc-shaped. The push rod 35 is slidably installed inside the slide rail 312. The front end of the push rod 35 has an annular groove 351 corresponding to the top bead 341. The rear end of the push rod 35 is connected to the pressure plate 352. A second elastic element 353 is provided between the pressure plate 352 and the rear end of the sleeve 31. The second elastic element 353 is a spring and is sleeved on the push rod 35. One end of the second elastic element 353 is fixedly connected to the pressure plate 352 to prevent the push rod 35 from sliding out of the slide rail 312.

[0037] In the above scheme, before the sliding rod 32 retracts into the sleeve 31, it presses the pressure plate 352 to drive the push rod 35 to move into the slide rail 312. At the same time, the second elastic element 353 is compressed. After the annular groove 351 on the push rod 35 aligns with the top ball 341, the sliding rod 32 is pushed into the sleeve 31, so that the guide sleeve 34 is located in the stepped groove 322 of the disc 321. The top ball 341 enters the annular groove 351 under the action of the stepped groove 322. When the guide sleeve 34 is fully entered into the stepped groove 322, the pressure plate 352 is released. Under the action of the second elastic element 353 and the pressure plate 352, the push rod 35 pushes the top ball 341 into the stepped groove 322. The top ball 341 is locked in the stepped groove 322 by the push rod 35, thereby limiting the position of the sliding rod 32.

[0038] In order to adjust the vertical position of the telescopic rod 3 relative to the wall according to the height of the wall, in this embodiment, the mounting frame 2 includes a lifting frame 21 and two fixing sleeves 22. The lifting frame 21 is U-shaped, and both ends of the lifting frame 21 are respectively inserted into the two fixing sleeves 22. Elastic columns are provided on both sides of one end of the lifting frame 21. Adjustment holes 221 corresponding to the elastic columns are opened on both sides of one of the fixing sleeves 22. By pressing the elastic column, the elastic column is separated from the adjustment hole 221 and the lifting frame 21 is pulled upward to adjust the height of the mounting frame 2, thereby realizing the adjustment of the height position of the telescopic rod 3 according to the overall height of the wall. At the same time, the telescopic effect of the mounting frame 2 facilitates the storage of the mounting frame 2. Support shafts 33 are provided on both sides of the front end of the sleeve 31. The support shafts 33 pass through the lifting frame 21 and are rotatably connected to the lifting frame 21.

[0039] The working principle of this utility model:

[0040] Before painting the wall, the telescopic rod 3 is in a retracted state, the top bead 341 is located in the stepped groove 322, and the first elastic element 36 is in a compressed state. First, adjust the distance between the base 1 and the wall, and then use the lifter 7 to make the telescopic rod 3 in the maximum tilt state so that the roller 4 can contact the upper or lower part of the wall after the telescopic rod 3 is extended.

[0041] Then press the pressure plate 352, and the pressure plate 352 drives the push rod 35 to move, so that the annular groove 351 on the push rod 35 corresponds to the top ball 341. At this time, the first elastic element 36 resets and pushes the disc 321 to move. The annular groove 351 on the disc 321 pushes the top ball 341 into the through hole 342. Due to the restriction of the guide block 323 by the threaded groove 313, the sliding rod 32 will slowly move to the outside of the sleeve 31 under the extension of the first elastic element 36, so as to avoid the sliding rod 32 from sliding out quickly due to the reset of the first elastic element 36.

[0042] Subsequently, the rear end of the telescopic rod 3 swings around the support shaft 33 via the lifting device 7, and the roller 4 moves up and down along the wall. At the same time, the liquid in the storage tank 5 is sprayed onto the roller 4 through the installation pipe 41 and the liquid hose 42, so that the roller 4 can paint the wall, thereby achieving the effect of automatically painting the wall.

[0043] Finally, when the telescopic rod 3 is retracted, the sliding rod 32 is pushed into the sleeve 31, and the pressure plate 352 is pressed down so that the annular groove 351 on the top rod 35 corresponds to the top ball 341. When the guide sleeve 34 enters the stepped groove 322 on the disc 321, the pressure plate 352 is released. Under the action of the second elastic element 353, the pressure plate 352 drives the top rod 35 to move, pushing the top ball 341 into the stepped groove 322, thereby completing the position limitation of the sliding rod 32.
