Abstract
The utility model relates to a dual-guide rail anti-swing lifting device. The lifting device comprises an inner sleeve and an outer sleeve sleeved at the peripheral side of the inner sleeve, wherein the inner sleeve is fixed on a lower end plate, the outer sleeve is fixed on an upper end plate, an electric pushrod is arranged in the inner sleeve, and the upper end of the electric pushrod is fixedly connected with the upper end plate; a dual-guide rod guide rail mechanism is further arranged in the inner sleeve and the outer sleeve, and comprises two guide rods fixed on the upper end plate and two layers of guide rods arranged at the upper end of the inner sleeve; and through holes which can be penetrated by the electric pushrod are opened in the middle parts of two layers of the guide plates, guide holes, for correspondingly guiding the guide rods, are respectively arranged in two sides of the through holes of two layers of the guide plates, and linear bearings, for correspondingly guiding and cooperating the guide rods, are respectively arranged in the guide holes at two sides of the through holes. According to the dual-guide rail anti-swing lifting device, the linear bearings and the guide rods are taken as an anti-swing guiding mechanism, because the linear bearings are contacted with the guide rods through steel balls in point contact manners, and the steel balls are in line arrangements, the contact area is small, the resistance is small, the contact is tight, and the rigidity of the steel ball is large, so that the lifting movement is smoother.
Description
Technical field
This utility model relates to the anti-lowering or hoisting gear that shakes of a kind of pair of guide rail.
Background technology
Liftable electric care bed present situation: base frame construction is generally adopted in (1), and it is to be supported on the underframe through two electric pushrods and connecting rod that nursing bed goes up and down, under push rod promotes; Tiltedly head on underframe nursing bed frame is gone up and down, this up-down is non-linear, and push rod, connecting rod and support are covered with a following confined space; Structure is thick; Cost is high, hinders new function expansion, hinders penetration and promotion; (2) have on the market two electric pushrods of usefulness are stood on head of a bed tail both sides respectively, the push rod lower end is fixed in and is equipped with on two wheel underframes, and the upper end heads on bedstead; The driving nursing bed goes up and down, and shakes for preventing nursing bed, and the long two guide rods of the employing that has stand on the push rod both sides; Long two guide rod difficult processing, cost is high, and moulding is unbecoming; The backup plate of head of a bed tail needs processing separately, is unfavorable for promoting; The use lifting column that has promptly is equipped with electric pushrod in the outer bush in the casting mold, drives nursing bed and goes up and down, though structure is simple, cost is high, is 3 to 5 times of electric pushrod, is difficult to carry out; (3) patent No. is that 201120037277.3 utility model patent discloses a kind of dual anti-lowering or hoisting gear that shakes; Though it is simple in structure, cheap that this device has; Handsome in appearance, can be used as that nursing bed goes up and down, the lowering or hoisting gear of head of a bed tailstock tilt function, but processing technique is difficult; And frictional force is bigger, and the stationarity of up-down also is not very good.
The utility model content
The purpose of this utility model is to provide a kind of pair of guide rail the anti-lowering or hoisting gear that shakes, and this device adopts linear bearing and guide rod to shake guiding mechanism as anti-, is the contact of steel ball point because linear bearing contacts with guide rod; Steel ball is again a linear array; Contact surface is little, and resistance is little, again can close contact; The steel ball rigidity is big, can make elevating movement more steady.
The technical scheme of this utility model is: a kind of pair of anti-lowering or hoisting gear that shakes of guide rail; Overlap and be sheathed on the overcoat of all sides of interior cover in comprising; Cover is fixed on the bottom plate in said, and overcoat is fixed on the upper head plate, is provided with electric pushrod in the said interior cover; The upper end and the upper head plate of electric pushrod are affixed; Also be provided with two guide rod guide rail mechanisms in said in cover and the overcoat, said pair of guide rod guide rail mechanism comprises two guide rods that are fixed on the upper head plate and the two-layer guide plate that is arranged on interior set upper side, and said two-layer guide plate middle part offers the through hole that electric pushrod can pass; Said two-layer guide plate is respectively arranged with the guide hole that is used for respective guide rod guiding in the both sides of through hole, be respectively arranged with in the guide hole of both sides to be used for the linear bearing that cooperates with the respective guide rod guiding.
Preferably, said linear bearing is the flange-type linear bearing.
Preferably, said linear bearing is a flange extended type linear bearing.
The advantage of this utility model is: (1) this pair guide rail is anti-to shake the simple in structure of lowering or hoisting gear, and manufacturing cost is lower; Processing technique is simple; (2) the anti-lowering or hoisting gear that shakes of this pair guide rail adopts electric pushrod to drive the upper head plate up-down, for the nursing bed expanded function provides the useful space; (3) adopting flange extended type linear bearing and guide rod to shake guiding mechanism as anti-, is the contact of steel ball point because linear bearing contacts with guide rod, and the steel ball of linear bearing is again a linear array, and contact surface is little; Resistance is little, again can close contact, and the steel ball rigidity is big; So when the monolateral loading of upper head plate, the linear bearing steel ball withstands guide rod; Prevent monolateral inclination, prevent that effectively the upper head plate bedstead from vacillating now to the left, now to the right, when upper head plate load moves up and down; Guide rod contacts with linear bearing guide rail point, and frictional force is little, moves up and down steadily.The upper head plate overcoat is for blocking internal structure, augmenting handsome in appearance simultaneously.
