Description

Adjustable height cloth art chair

Technical field

The utility model belongs to convenience type adjustable seat tool field, relates in particular to a kind of adjustable height cloth art chair.

Background technology

Existing liftable seat roughly is divided into two kinds of situations from Adjusting Mechanism: (1) spiral lifting method promptly reaches the purpose of lifting by the rotary seat working face.Weakness such as this mode of tuning exists manual operations, and labour intensity is big, in addition actual when carrying out lift work, because of the rotation of seat working face, the people must stand up.(2) hydraulic pushing or unloading lifting and lowering method promptly realize adjusting purpose highly by hydraulicefficiency elevation structure.Though this pushing tow or unloading manner have solved the problem that the seat working face need not rotate with height change to a certain extent, above-mentioned lift work still needs manually-operated, and the structure of its auxiliary equipment is comparatively complicated.

The utility model content

The utility model is intended to overcome the deficiencies in the prior art part and provides a kind of simple in structure, and is convenient and strength-saving, and the automaticity height can be adjusted the adjustable height cloth art chair of position flexibly.

For achieving the above object, the utility model is achieved in that

A kind of adjustable height cloth art chair, it comprises cloth art chair body and base; On described base, be fixed with elevating mechanism; The driving gear that described elevating mechanism comprises motor, fixedly connect with described motor output shaft, driven gear, leading screw, the screw that connects with described leading screw, and fixedly sleeved lifting column and the shell body of described screw with the driving gear engagement; The inwall of described shell body is fixed with can be along the position limiting slide block of lifting column longitudinal sliding motion; Bottom at described leading screw is provided with axle sleeve; The inwall of described axle sleeve and shell body is affixed; The bottom of described lifting column and cloth art chair body is affixed; The bottom and the base of described elevating mechanism fixedly connect.

As a kind of preferred version, the utility model is fixed with bearing on described base; The pillar and the bearing of base are affixed.

As another kind of preferred version, the utility model is fixed with operated key on described cloth art chair body.

In addition, motor described in the utility model can be three; The driving gear that fixedly connects on each motor output shaft meshes with driven gear respectively; The axial connecting line of three driving gears is equilateral triangle.

The utility model is simple in structure, and is laborsaving, the automaticity height.The angle of cloth art chair body be can adjust flexibly by the base bearing, thereby convenient, practical purpose reached.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and the specific embodiments.Protection domain of the present utility model will not only be confined to the statement of following content.

Fig. 1 is an overall structure schematic diagram of the present utility model;

Fig. 2 is the utility model elevating mechanism part-structure schematic diagram;

Fig. 3 is the utility model elevating mechanism gear distribution map.

The specific embodiment

As shown in Figure 1, 2, a kind of adjustable height cloth art chair comprises cloth art chair body 1 and base 3; On described base 3, be fixed with elevating mechanism 2; The driving gear 5 that described elevating mechanism 2 comprises motor 4, fixedly connect with described motor 4 output shafts, driven gear 6, leading screw 7, the screw 8 that connects with described leading screw 7, and fixedly sleeved lifting column 9 and the shell body 10 of described screw 8 with driving gear 5 engagements; The inwall of described shell body 10 is fixed with can be along the position limiting slide block 11 of lifting column 9 longitudinal sliding motions; Be provided with axle sleeve 12 in the bottom of described leading screw 7; Described axle sleeve 12 is affixed with the inwall of shell body 10; Described lifting column 9 is affixed with the bottom of cloth art chair body 1; The bottom of described elevating mechanism 2 and base 3 fixedly connect; On described base 3, be fixed with bearing 13; The pillar 14 of base 3 is affixed with bearing 13; On described cloth art chair body 1, be fixed with operated key 15.As Fig. 3, for keeping the stability of system, motor 4 described in the utility model is three; The driving gear 5 that fixedly connects on each motor 4 output shaft meshes with driven gear 6 respectively; The axial connecting line of three driving gears 5 is equilateral triangle.

The utility model in use, by open operation key 15, make 4 work of three motors, three driving gears 5 drive driven gear 6 rotations, driven gear 6 drives leading screw 7 rotations, and lifting column 9 is owing to the effect of position limiting slide block 11 only can be moved along leading screw 7 longitudinal axis, and screw 8 is fixedly sleeved with lifting column 9, thereby make screw 8 rise or descend along axis, finally finish lift work with lifting column 9.
