Abstract
An electric lifting chair comprises a base, a seat cushion, a bracket at the bottom of the seat cushion, and an electric lifting mechanism positioned between the base and the bracket; the electric lifting mechanism comprises an outer sleeve, an electric push rod body and a motor, wherein the electric push rod body and the motor are positioned in the outer sleeve; a push rod is arranged in the electric push rod body; the outer sleeve comprises an upper cover plate, a lower cover plate and a supporting pipe positioned between the upper and the lower cover plate; a through hole is formed on the upper cover plate and allows the push rod to extend out from the upper cover plate; and a positioning sleeve matched with the electric push rod body in diameter and sleeved on the outer side of the electric push rod body is arranged on the inner surface of the upper cover plate. By adopting the structure combining the electric push rod body with the positioning sleeve and the supporting pipe, not only can the strength of the electric lifting mechanism be increased, but also the radial force that the push rod and the electric push rod body receive while moving can be transmitted, so that the electric push rod body and the push rod are prevented from shaking in the radial direction, and the stationarity of lifting can be improved.
Description
Technical field
The utility model relates to a kind of electric up-down chair.
Background technology
Often need the career field of adjustment podium level at some,, need regulate the height of beauty treatment chair or hairdressers' chair,, need the height of adjusting patient's seat to make things convenient for the doctor to operate equally such as at medical field like the cosmetology industry.Common chair height is regulated; Adopt mechanical-hydraulic elevating mechanism or pressure liftable mechanism mostly; But there is bigger potential safety hazard in pressure liftable mechanism to human body, and the gentle voltage rise descending mechanism of mechanical-hydraulic elevating mechanism all needs staff to operate, and uses the inconvenience that operates.
Therefore some electronic chair lifts have appearred; Like Chinese patent CN101496684A disclosed a kind of " Motorized lift device ", this Motorized lift device can be applied to the electric up-down chair, comprises body; And be arranged at intrinsic screw mandrel push rod; Propelling driving push rod through reducing motor moves up with respect to body, and the push rod top can connect the seat cushion of chair, and the body below is fixed on the base.But such Motorized lift device; Only depend on body and push rod to support whole seat cushion; In the process that seat cushion moves up and down along with push rod, the radial load of generation is easy to cause the double swerve of seat cushion, makes this Motorized lift device steady transverse shakiness easily inadequately when going up and down.
Summary of the invention
The utility model technical problem to be solved provides a kind of up-down electric up-down chair stably.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of electric up-down chair; Comprise base; Seat cushion, the carriage of seat cushion bottom, and the electric lifting mechanism between said base and carriage; It is characterized in that: said electric lifting mechanism comprises overcoat; And the electric pushrod body and the motor that are positioned at overcoat, having push rod in the said electric pushrod body, this push rod can be under the driving of motor upwards stretches out or shrinks with respect to the electric pushrod body and is positioned at this electric pushrod body; Said overcoat comprises upper cover plate, lower cover and at the stay pipe between the cover plate up and down; The bottom of said electric pushrod body is fixed on the lower cover, have through hole on the said upper cover plate and supply push rod to stretch out from upper cover plate, and the inner surface of this upper cover plate has the positioning sleeve that diameter with this electric pushrod body is complementary and is placed in the electric pushrod body outside.This electric pushrod body and positioning sleeve, stay pipe structure combining; Not only can reinforce the intensity of electric lifting mechanism; And can the radial load that push rod and electric pushrod body receive at the volley be transmitted; Prevent radially rocking of electric pushrod body and push rod, improved the stationarity of going up and down.
Preferably, said upper cover plate and stay pipe are one-body molded, fix through screw bolt and nut between said lower cover and the stay pipe.
Preferably, for the ease of installing, the top of said push rod has the first connecting portion said carriage that is connected to, and the bottom of said lower cover has the second connecting portion said base that is connected to.
For the ease of installing and processing, all has tapering on said first connecting portion and second connecting portion.
Compared with prior art; The advantage of the utility model is that this electric up-down chair not only can reinforce the intensity of electric lifting mechanism; And can the radial load that push rod and electric pushrod body receive at the volley be transmitted; Prevent radially rocking of electric pushrod body and push rod, improved the stationarity of going up and down.
Description of drawings
Fig. 1 is the sketch map of the utility model electric up-down chair.
Fig. 2 is the sketch map of the electric lifting mechanism of the utility model electric up-down chair.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
The electric up-down chair of the utility model, as shown in Figure 1, comprise seat cushion 4, handrail 5, backrest 6, be positioned at the carriage 3 of seat cushion 4 bottoms and the base 1 of seat bottom.Between base 1 and carriage 3, be connected with electric lifting mechanism 2, driven bracket 3 and seat cushion 4 move upward.
As shown in Figure 2, electric pushrod body 7 and motor 9 that this electric lifting mechanism 2 comprises overcoat 8 and is positioned at overcoat 8.Have push rod 71 in this electric pushrod body 7, under the driving of motor 9, upwards stretch out or shrink in electric pushrod body 7 with respect to electric pushrod body 7.This overcoat 8 comprises the stay pipe 83 between upper cover plate 81, lower cover 82 and the upper and lower cover plate, and this electric pushrod body 7 and motor 9 all are positioned at stay pipe 83, and the bottom of electric pushrod body 7 is fixed on the lower cover 82 through firm welding.
Has the through hole that supplies push rod 71 to stretch out on the upper cover plate 81; And the inboard of this upper cover plate 81 has the positioning sleeve 84 that is complementary with the diameter of electric pushrod body 7; This positioning sleeve 84 is placed in the outside of electric pushrod body 7, and push rod 71 is passed to upper cover plate 81 and stay pipe 83 in the radial load that when electric pushrod body 7 stretches, receives through positioning sleeve 84.Therefore; Overcoat 8 has not only been strengthened the whole fastness of electric lifting mechanism; But also the radial load that electric pushrod body 7 and push rod 71 receive is at the volley transmitted, prevented radially rocking of electric pushrod body 7 and push rod 71, improved the stationarity of going up and down.
