The utility model discloses a higher material of screw rod sleeve optional density is made to make the screw rod sleeve have basis weight, so that the lead screw can not swing under the effect of gravity. The screw rod sleeve can be selectively fixed on the screw rod, and can also be selectively sleeved on the screw rod directly, and the screw rod sleeve can not be separated from the screw rod and can slide upwards due to the vertical arrangement of the screw rod and the anti-impact gasket arranged at the lower end of the screw rod. Wherein, because the existence of scour protection gasket, and the screw rod sleeve can be that direct cover is established on the lead screw not with the lead screw rigidity fixed, when screw-nut dashes the top, deformation can take place for scour protection gasket, and the screw rod sleeve can be hit and reciprocate to avoid screw-nut card at the lead screw top.
Preferably, the anti-impact pad at least comprises an upper pad, a middle pad and a lower pad which are stacked up and down, and the middle pad is clamped between the upper pad and the lower pad. The utility model discloses a scour protection gasket has the three-layer at least, and well gasket can be made by the material that has certain elasticity, goes up the gasket and can adopt the better material of compressive strength to make with lower gasket, and the aforesaid sets up so that the utility model discloses scour protection gasket's scour protection top effect is better.
As preferred, the lead screw end fixing has the mounting, the mounting includes pole portion and spacing portion, pole portion is fixed mutually with the lead screw, spacing portion is located pole portion lower extreme, pole portion external diameter is less than the lead screw external diameter in order to be formed with the stair structure, the scour protection gasket cover is established on the pole portion and limited spacing portion with the stair face of stair structure with between. The above arrangement is used for axial spacing and fixation of the anti-impact gasket.
Preferably, the axial surface of the lower end of the screw rod is concave to form a threaded hole, and the upper end of the rod part is fixed in the threaded hole in a threaded manner. The aforesaid sets up to be convenient for the utility model discloses the mounting is fixed with the lead screw.
Preferably, pole portion circumference outside cover is equipped with fixed cover, the fixed cover cross-section personally submits the annular setting, and a plurality of protecting against shock gasket cover are established the fixed cover circumference outside, fixed cover by the restriction spacing portion with between the step face of stair structure, fixed cover axial length is greater than the sum of all protecting against shock gasket thickness. The anti-impact gasket can also slide along the axial direction of the fixed sleeve to a certain extent so as to further avoid the lead screw nut from being clamped at the end part of the lead screw.
The utility model has the advantages of can avoid the lead screw to prevent shaking and can avoid screw-nut to dash the top.
