Description

Technical Field

[0001] The utility model relates to the technical field of screw jacks, in particular to a suspended adjustable screw jack. Background Art

[0002] When the screw jack is used daily, it is connected to the screw jack through an additional steel pipe, which can be connected to the cylindrical sleeve on the screw jack, and the steel pipe is pushed to rotate, thereby driving the sleeve and the rotating shaft in the screw jack to rotate, thereby rotating the bevel gear on the rotating shaft. A threaded rod is placed vertically in the screw jack, and the bottom of the threaded rod is connected to the bottom of the inner wall of the screw jack through a bearing. At the same time, a bevel gear is also installed on the threaded rod, and this bevel gear is meshed with the bevel gear on the rotating shaft. The bevel gear on the rotating shaft will drive the bevel gear on the threaded rod, thereby rotating the threaded rod. The top of the threaded rod is a threaded connection with an upwardly moving cylinder, and there is a vertical slide groove on this cylinder. This slide groove is slidably connected to the fixed block installed on the inner wall of the screw jack, so that when the threaded rod rotates, it will make a threaded motion with the cylinder, thereby causing the cylinder to move upward, thereby lifting the object.

[0003] When the screw jack is working, the steel pipe is often too long, and the distance between the object to be lifted and the ground is short, so the steel pipe cannot enter. At the same time, the steel pipe is separated from the screw jack. When carrying the screw jack, it is easy to lose the steel pipe in a corner. It takes time to find the steel pipe, which will delay the user's work.

[0004] Therefore, it is necessary to invent a kind of suspension adjustable screw jack. Summary of the invention

[0025] The bottom of the connecting rod 14 is threadedly connected to the inner wall of the top of the fixed cylinder 13, and a groove 15 is provided on the outer wall of the top of the connecting rod 14. The bottom of the rotating rod 17 is fixedly connected to the top of the protrusion 16, and the outer walls on the left and right sides of the protrusion 16 are respectively rotatably connected to the left and right sides of the inner wall of the groove 15. When the screw jack is working, the screw jack is first placed under the object to be jacked up, and the side of the threaded rod 4 away from the base 1 is fixedly connected to the back of the rotating block 12, and the top of the rotating block 12 is fixedly connected to the bottom of the fixed cylinder 13. After the screw jack is placed under the object to be jacked up, the rotating block 12 and the fixed cylinder 13 are driven to rotate by pushing the connecting rod 14 or the rotating rod 17.

[0026] The bottom right side of the rotating rod 17 is fixedly connected to the top of the connecting page 18, the left outer wall of the connecting page 18 is in contact with the right outer wall of the connecting rod 14, and the right inner wall of the connecting page 18 is threadedly connected with a bolt 19, and the left outer wall of the bolt 19 is in contact with the right outer wall of the connecting rod 14. When the distance between the object to be lifted and the ground is relatively close, the rotating rod 17 needs to be rotated so that the rotating rod 17 and the connecting rod 14 are in a vertical state. After the rotation, the bolt 19 is rotated into the connecting page 18 to fix the rotating rod 17.

[0027] The outer wall of the rotating shaft 10 is rotatably connected to the inner wall of the connecting tube 3, the rotating shaft 10 and the threaded rod 4 are perpendicular to each other, the outer wall of the rotating shaft 10 is fixedly connected to the inner wall of the gear 2 11, the outer wall of the gear 2 11 is meshed with the gear 1 5, and when the state between the rotating rod 17 and the connecting rod 14 is adjusted, it is necessary to keep rotating the rotating rod 17 and the connecting rod 14 to rotate the rotating shaft 10, so that the rotating shaft 10 drives the gear 2 11, and the gear 2 11 drives the gear 1 5 to rotate, and the gear 1 5 and the gear 2 11 are both bevel gears, which can be meshed at 90°.
