Abstract
An electric lift chair containing a seat is characterized in that: the electric lift chair contains a lift mechanism which comprises a gear-down motor, a driving bevel gear, a driven bevel gear, a screw shaft, a screw nut and a lift jacket. The connection relationship among the components is as follows. The gear-down motor is connected with the driving bevel gear through a driving bevel gear key; the driving bevel gear engages with the driven bevel gear; the gear is connected with screw shaft through a driven gear key; the screw shaft is connected with the screw thread of the screw nut; the screw nut is interference fit to the lift jacket; the lift jacket is transition fit with to a shell body; the positioning guide roll ball is positioned between the shell body and the lift jacket. A positioning internal jacket and a positioning external jacket are positioned at the positioning guide roll ball. Compared with the prior art, the utility model has the advantages of novel design, simple structure, high automation and being easy to use. The electric lift chair also can be applied in other equipment and products that require a regular adjustment of platform height.
Description
Technical field: the utility model relates to a kind of needs and often adjusts the electronic lifting seat of the career field of podium level, as industries such as: cosmetology, medical tooth sections.
Background technology: the adjustment structure of existing liftable seat is broadly divided into two kinds, and a kind of is the spiral lifting method, reaches the purpose of lifting by the rotary work table top.Its shortcoming is: (1) is manual, labour intensity height, heaviness; (2) do not need work top to rotate under a lot of situations.Another is to adopt the hydraulic lifting structure, descends by hydraulic lifting and unloading, realize regulating the purpose of height, though it has solved the problem that work top need not rotate with height change, still has operation manually.
Summary of the invention: the purpose of this utility model is at above-mentioned the deficiencies in the prior art, and provides a kind of electric up-down seat to people.For achieving the above object, the utility model adopts following technical proposals: the electric up-down seat, comprise seat (21), and it also comprises elevating mechanism (20).Elevating mechanism (20) is mainly by reducing motor (19), active oblique gear (2), passive helical gear (5), leading screw (12), screw (13), lifting cover (14) is formed, its annexation is: reducing motor (19) connects active oblique gear (2) by active oblique gear key (1), active oblique gear (2) and passive helical gear (5) engagement, gear (5) is connected with leading screw (12) by driven gear key (8), leading screw (12) is threaded with screw (13), screw (13) and lifting cover (14) interference fit, lifting cover (14) and housing (15) interference fits, positioning and guiding ball (16) places between housing (15) and the lifting cover (14).Cover (17) and location overcoat (18) in described positioning and guiding ball (16) the peripheral hardware location.
The utility model compared with prior art has the high advantage of novel, simple in structure, convenient and strength-saving, automatic degree.This electric up-down part also can be applicable to other to be needed often to adjust on the equipment and product of podium level.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of lowering or hoisting gear among Fig. 1.
The specific embodiment:
With reference to Fig. 1,2, the electric up-down seat, comprise seat 21, it also comprises elevating mechanism 20, elevating mechanism 20 is mainly by reducing motor 19, active oblique gear 2, passive helical gear 5, leading screw 12, screw 13, lifting cover 14 is formed, its annexation is: reducing motor 19 connects active oblique gear 2 by active oblique gear key 1, active oblique gear 2 and passive helical gear 5 engagements, gear 5 is connected with leading screw 12 by driven gear key 8, leading screw 12 is threaded with screw 13, screw 13 overlaps 14 interference fit with lifting, and lifting cover 14 and housing 15 interference fits, positioning and guiding ball 16 place between housing 15 and the lifting cover 14 and play the guiding role.Cover 17 and location overcoat 18 in the described positioning and guiding ball 16 peripheral hardwares location.The lower end of described leading screw 12 is provided with bearing 11.
Operation principle: during use, pole changer by the control reducing motor makes the driving gear rotation drive the driven gear rotation, leading screw rotation in driven gear drives by key, the lifting cover is owing to the restriction of positioning and guiding ball can not be rotated, and interior screw and lifting cover are interference fit, thereby screw rises or descends along axis with the lifting cover in making.
