[0012] 1. The hydraulic lift with anti-tilt function is provided with a sliding plate, a threaded bolt, a rotating wheel, a rubber pad, a slot, a snap plate and a torsion spring. The staff rotates the threaded bolt through the rotating wheel so that the threaded bolt pushes the rubber pad downward to move so that the rubber pad is in close contact with the ground, thereby supporting and fixing the base to prevent the hydraulic lift from moving accidentally. The staff rotates the snap plate to disengage the snap plate from the slot, and at the same time the torsion spring will be twisted, so that the staff can pull the sliding plate out of the movable plate, and then release the snap plate to insert the block plate into the slot through the rotation of the torsion spring to fix the position of the sliding plate, thereby increasing the distance between the rubber pad and the base, increasing the support surface of the hydraulic lift, improving the working stability, and preventing the hydraulic lift from tipping over due to the shift of the center of gravity.

The threaded rod is rotated by a motor so that the moving blocks connected at both ends of the threaded rod can move toward each other. When the moving block moves, the angle between the first connecting plate and the second connecting plate changes. At the same time, the sliding rod will also slide in the second sliding groove, thereby pushing the movable plate to move through the first connecting plate and the second connecting plate, so that the movable plate can be away from the base, thereby expanding the distance between the rubber pad and the base, increasing the supporting area formed by the rubber pad and the base, and improving the working stability of the hydraulic lift.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a hydraulic lift with an anti-tilt function, comprising a base 1, a hydraulic lift body 2 is installed on the base 1, slotted plates 3 are connected on both sides of the base 1, and a mounting plate 4 is connected to the slotted plate 3 on one side of the base 1, a threaded rod 5 is rotatably connected in the slotted plate 3, and a motor 20 is installed on the mounting plate 4, the output shaft of the motor 20 is connected to the threaded rod 5, and the end of the threaded rod 5 away from the motor 20 is connected to a driving wheel 21, and a synchronous belt 22 is installed on the driving wheel 21, and the driving wheel 21 is connected to a driven wheel 23 through the synchronous belt 22, and the driven wheel 23 is connected to the threaded rod 5 in the slotted plate 3 connected to the other side of the base 1, and the driving wheel 21 and the driven wheel 23 are connected together through the synchronous belt 22, so that the motor 20 can drive the two threaded rods 5 to rotate at the same time, so that the movable plates 10 on both sides of the base 1 move synchronously, so that the rubber pads 18 are evenly distributed on both sides of the base 1, so as to avoid the uneven distribution of support points causing the hydraulic lift to tip over.

[0021] A first slide groove 6 is provided inside the slotted plate 3, and moving blocks 7 are threadedly connected at both ends of the threaded rod 5. A second slide groove 24 is provided on the movable plate 10, and a sliding rod 26 is slidably connected in the second slide groove 24. A slider 27 is connected to one side of the moving block 7, and the slider 27 slides in the first slide groove 6. Through the threads with opposite directions at both ends of the threaded rod 5, the two moving blocks 7 can move in opposite directions along the threaded rod 5, and at the same time, the slider 27 will slide in the first slide groove 6, so that the slider 27 can move smoothly and prevent the moving block 7 from rotating and tilting during movement.

[0022] The moving block 7 connected to one end of the threaded rod 5 is connected to a first connecting plate 8, and the moving block 7 connected to the other end of the threaded rod 5 is connected to a second connecting plate 9. The first connecting plate 8 and the second connecting plate 9 are cross-connected, and a connecting rod 25 is rotatably connected at the intersection of the first connecting plate 8 and the second connecting plate 9. The first connecting plate 8 and the second connecting plate 9 are connected to the ends away from the moving block 7. The first connecting plate 8 and the second connecting plate 9 are slidably connected to a movable plate 10 at one end, and a snap plate 11 is rotatably connected to the movable plate 10. A sliding plate 13 is slidably connected inside the plate 10, and a plurality of slots 28 are provided on the sliding plate 13. The snap plate 11 is designed in an L shape, and the snap plate 11 is inserted into the slot 28. Torsion springs 12 are connected to both sides of the snap plate 11, and one end of the torsion spring 12 is connected to the movable plate 10. The torsion spring 12 rotates so that the snap plate 11 can be always inserted into the slot 28, thereby fixing the sliding plate 13 to prevent the sliding plate 13 from accidentally sliding and causing unstable support. The plurality of slots 28 can increase the adjustment range and improve applicability.

[0023] One end of the sliding plate 13 is connected to a connecting block 14, a threaded sleeve 15 is installed on the connecting block 14, a threaded bolt 16 is threadedly connected to the threaded sleeve 15, one end of the threaded bolt 16 is connected to a rotating wheel 17, and the other end of the threaded bolt 16 is connected to a rubber pad 18. Both ends of the threaded rod 5 are provided with threads in opposite directions, a universal wheel 19 is installed under the base 1, and anti-skid patterns are provided under the rubber pad 18. The rubber pad 18 is brought into contact with the ground by rotating the threaded bolt 16, and the protective patterns under the rubber pad 18 can increase the friction with the ground, thereby preventing the hydraulic lift from sliding and improving the working stability of the hydraulic lift.

[0024] The working principle of the utility model is:

[0025] The motor 20 is started, and the driving wheel 21 and the driven wheel 23 are connected together by the synchronous belt 22, so that the motor 20 can drive the two threaded rods 5 to rotate at the same time. The rotation of the threaded rod 5 enables the two moving blocks 7 on the threaded rod 5 to move in opposite directions. When the moving blocks 7 move, the angle between the first connecting plate 8 and the second connecting plate 9 changes, so that the movable plate 10 is pushed to move by the first connecting plate 8 and the second connecting plate 9, and the lateral distance between the rubber pad 18 and the base 1 is increased. The staff can also rotate the buckle plate 11 to make the buckle The plate 11 is disengaged from the slot 28, allowing the staff to pull the sliding plate 13, increasing the longitudinal distance between the rubber pad 18 and the base 1, thereby expanding the support point and preventing the hydraulic lift from tipping over. As the snap plate 11 rotates, the torsion spring 12 will be twisted, and the snap plate 11 will be reinserted into the slot 28 through the rotation of the torsion spring 12, thereby fixing the sliding plate 13. Finally, the staff rotates the threaded bolt 16 so that the threaded bolt 16 pushes the rubber pad 18 downward to move, so that the rubber pad 18 is in close contact with the ground, thereby supporting and fixing the base 1.
