[0002] A screw lift is a mechanical device used for vertical movement, usually consisting of a rotating screw and a nut that fits with it. By rotating the screw, the nut moves along the screw thread, thereby achieving lifting and lowering movement. Screw lifts are commonly used in various occasions that require precise control of height or position, such as adjusting industrial equipment, lifting and lowering platforms, opening and closing doors and windows, etc. They can be manually operated or equipped with electric or hydraulic systems for automatic control.

[0003] Although the current screw lifting device is widely used, when the screw lifting body is installed, a matching mounting plate is usually used and the mounting plate is fixed to the equipment using bolts, and the screw lifting body and the mounting plate are usually arranged in one piece, which will result in that multiple bolts need to be unscrewed to complete the disassembly and assembly of the mounting plate during installation or disassembly and replacement. Using multiple screws to fix the screw lifting device may increase the complexity of installation. When disassembling, each screw needs to be installed and tightened one by one, which makes maintenance more troublesome. Utility Model Content

[0024] The limiting shell 12 is arranged on both sides of the bottom of the aluminum alloy base 1 . The inner cavity of the limiting shell 12 is provided with a mounting assembly 13 used for mounting the aluminum alloy base 1 . The mounting assembly 13 includes a screw 1301 and an insert block 1302 .

[0025] The screw 1301 is installed on the inner wall of the limiting shell 12 through a bearing, and the plug block 1302 is arranged on the front and rear sides of the inner cavity of the limiting shell 12. The other end of the screw 1301 passes through the outer side of the limiting shell 12 and is fixedly connected with the torsion block 1303. A movable plate 1304 is sleeved on the surface of the screw 1301. Both sides of the inner cavity of the movable plate 1304 are provided with fixed rods 1311 for limiting the movement of the movable plate 1304. Both ends of the fixed rod 1311 are fixedly connected to the inner wall of the limiting shell 12. Guide wheels 1305 are arranged on the front and rear sides of one side of the movable plate 1304. The bottom of the guide wheel 1305 is movably connected with the plug block 1302 through a bearing. The bottom of the plug block 1302 is fixedly connected to the limiting plate 1306. Twisting the torsion block 1303 can make the screw 1301 cooperate with the movable plate 1304 to move. At this time, the movable plate 1304 will move within a limited position on the surface of the fixed rod 1311. 4 will gradually press against the guide wheel 1305 when it moves, and the two sides of the moving plate 1304 are inclined, so the guide wheel 1305 will drive the plug block 1302 to move when it moves. At this time, the plug block 1302 will drive the limiting plate 1306 to stretch the third spring 1309 on the surface of the limiting rod 1307 to move, so that the plug block 1302 is separated from the mounting base 14. The inner cavity of the limiting plate 1306 is provided with a limiting rod 1307, and one end of the limiting rod 1307 It is fixedly connected to the inner wall of the limiting shell 12, the other side of the limiting rod 1307 is fixedly connected to an extension plate 1308, both sides of the extension plate 1308 are fixedly connected to the inner wall of the limiting shell 12, the limiting plate 1306 is fixedly connected to one side of the inner wall of the limiting shell 12 with a third spring 1309, one side of the extension plate 1308 is fixedly connected to a reinforcement plate 1310, and the side of the reinforcement plate 1310 close to the inner wall of the limiting shell 12 is fixedly connected to the inner wall of the limiting shell 12.

[0026] A mounting base 14 is provided at the bottom of the aluminum alloy base 1, and mounting holes 104 are opened inside the mounting base 14. The mounting holes 104 are arranged in an array inside the mounting base 14, and the mounting assembly 13 is conveniently installed through the mounting holes 104. A support plate 141 is fixedly connected to the top of the mounting base 14. Through the contact between the support plate 141 and the aluminum alloy base 1, it can be pressed to provide a certain stability for the device when in use. The top of the support plate 141 is in active contact with the aluminum alloy base 1, and the mounting base 14 is initially installed on the device to be installed through the mounting hole 104, and then the screw lifter is conveniently installed on the mounting base 14 quickly through the mounting assembly 13, and it is also convenient to quickly disassemble it, so that there is no need to remove multiple screws when disassembling the screw lifter, and the screw lifter can be disassembled and assembled.

[0027] Working principle: When the screw lifting body needs to be installed, firstly, the aluminum alloy base 1 drives the limit shell 12 to align with the installation base 14, and the support plate 141 is fitted with the aluminum alloy base 1, and then the torsion block 1303 is twisted to rotate the screw 1301. At this time, the moving plate 1304 will gradually separate from the surface of the guide wheel 1305. At this time, the limit plate 1306 will also be reset by the third spring 1309 to make the insert block 1302 gradually move, so as to be inserted into the installation base 14, so as to facilitate the installation of the aluminum alloy base 1. If it needs to be disassembled, twist the torsion block 1 303 can make the screw rod 1301 cooperate with the movable plate 1304 to move. At this time, the movable plate 1304 will move in a limited position on the surface of the fixed rod 1311. When the movable plate 1304 moves, it will gradually press against the guide wheel 1305, and the two sides of the movable plate 1304 are inclined. Therefore, when the guide wheel 1305 moves, it will drive the plug block 1302 to move. At this time, the plug block 1302 will drive the limiting plate 1306 to stretch the third spring 1309 on the surface of the limiting rod 1307 to move, so that the plug block 1302 is separated from the mounting base 14.
