Description

Manual lead screw lifter

Technical Field

The utility model relates to a elevating gear technical field, in particular to manual lead screw riser.

Background

The lifter is the device of certain equipment of going up and down through certain transmission mode as the name suggests, for example some utilize the lift that slider spout relative motion formed, and it is inseparable to scarf joint between this kind of structure slider and the spout, perhaps when fixing some weight objects on the slider, produces easily and slides, leads to going up and down to skid, influences the result of use, has the potential safety hazard, consequently, a steady structure, firm manual lead screw lifter of special research.

SUMMERY OF THE UTILITY MODEL

The utility model overcomes prior art is not enough, provides a manual lead screw riser, this riser simple structure, and workable, convenient operation utilizes the bevel gear to turn into the vertical motion with rotary motion, realizes going up and down.

The utility model discloses a realize through following technical scheme: a manual screw rod lifter comprises a base and is characterized in that an inner cylinder is arranged on the base, an outer cylinder is arranged on the outer side of the inner cylinder, a fixed shaft is arranged on one side of the outer cylinder, and a protective cover is arranged at the top of the outer cylinder; and a crank is arranged on one side of the protective cover, the crank is connected with a first bevel gear, the first bevel gear is meshed with a second bevel gear, the second bevel gear is connected with a screw, the screw penetrates through a threaded connection nut of the protective cover, the nut is fixed on the inner barrel, and a thrust ball bearing is further arranged at the connection position of the screw and the protective cover.

Preferably, the crank is provided with a handle sleeve.

Preferably, the fixed shaft is a hollow cylinder.

The utility model has the advantages that: the utility model has simple structure and easy processing; the lifting is realized by shaking the crank, so that the operation is simple and safe; under the combined action of the screw, the nut, the bevel gear and the thrust ball bearing, the rotary motion of the side handle is converted into the vertical lifting motion of the outer cylinder, so that the lifting of the outer cylinder and the fixed shaft is realized.

Detailed Description

In order to make the objects, technical solutions and advantageous effects of the present invention more clear, the following embodiments are combined to further explain the technical solutions of the present invention.

As shown in fig. 1 to 4, the manual screw rod lifter comprises a base 1, and is characterized in that an inner cylinder 2 is arranged on the base 1, an outer cylinder 3 is arranged on the outer side of the inner cylinder 2, a fixing shaft 5 is arranged on one side of the outer cylinder 3, the fixing shaft 5 is a hollow cylinder, and a protective cover 10 is arranged on the top of the outer cylinder 3; a crank 12 is arranged on one side of the protective cover 10, and a handle sleeve 13 is arranged on the crank 12. The crank 12 is connected with a first bevel gear 8, the first bevel gear 8 is meshed with a second bevel gear 9, the second bevel gear 9 is connected with a screw rod 4, the screw rod 4 penetrates through a protective cover 10 and is in threaded connection with a nut 6, the nut 6 is fixed on the inner cylinder 2, and a thrust ball bearing 7 is further arranged at the connection position of the screw rod 4 and the protective cover 10.

When the lifting device is used, a motor home or a container is connected with the lifter through the fixed shaft 5, and after the connection is finished, the crank 12 is manually shaken to drive the motor home to move up and down through the fixed shaft 5; and when the crank 12 is shaken, the first bevel gear 8 rotates, so that the second bevel gear 9 meshed with the first bevel gear 8 rotates, the second bevel gear 9 rotates to drive the screw rod 4 to rotate, and the screw rod 4 rotates to drive the outer cylinder 3 to move up and down along the inner cylinder 2 due to the fact that the nut 6 is fixed, so that the lifting is realized.

The utility model aims at lifting 3-5 tons, dragging the car as a house or the container, welding the container, and fixing the unhooking position of the car as a house without moving time and labor back and forth, wherein the lifting stroke is 300-400 mm.

Other technical features than those described in the specification are known to those skilled in the art.
