Abstract

The utility model relates to a mechanical lifting swivel chair, comprising a chair seat, a chair back, a chair leg bracket and a lifting device, a swiveling mechanism is arranged above the chair leg bracket; the lower end of the lifting device is connected with the swiveling mechanism and the upper end is connected with the chair seat. The lifting device comprises a drive bolt which is provided with right-and-left thread, a screw cap sheathed at the two ends of the drive bolt and a rhombic rack; the right end and the left end of the rhombic rack are articulated on the screw cap, the lower end is articulated on the swiveling mechanism and the upper end is articulated on the chair seat. The swiveling mechanism comprises an outer sleeve, an inner spindle and a bearing between the outer sleeve and the inner spindle. One end of the drive bolt is connected with a lifting rocking handle used for controlling the height of the chair seat. By adopting the deformability of rhombus and the self-lock mechanism of thread, the mechanical lifting swivel chair can be conveniently lifted, and also has simple structure, convenient manufacture and low cost and is suitable for being popularized and applied.

Description

The mechanical elevating swivel chair
(1) technical field
The utility model relates to the chair technical field, particularly a kind of adjustable for height mechanical elevating swivel chair.
(2) background technology
Advantages such as swivel chair is comfortable flexibly because of it, and height and direction are adjustable are widely used.But common swivel chair lifting is not too convenient, the needs rotation seat that has, and the heavy burden that the needs that have increase or reduce seat realizes lifting.
(3) summary of the invention
The utility model provides a kind of simple in structure, easy to operate mechanical elevating swivel chair in order to solve common swivel chair lifting problem not too easily.
The utility model is realized by following measure: a kind of mechanical elevating swivel chair, comprise seat, and the chair back, chair foot support and lowering or hoisting gear, described chair foot support top is provided with whirligig; Described lowering or hoisting gear lower end is connected with whirligig, and the upper end is connected with seat.
The further improvement of the utility model part is: described lowering or hoisting gear comprises and is provided with right-and-left threaded drive screw, be sleeved on the nut at drive screw two ends, the rhombus frame, the two ends, the left and right sides of described rhombus frame are hinged on the nut, the lower end is hinged on the whirligig, and the upper end is hinged on the seat.
Further improvements of the present utility model are: described whirligig comprises outer tube, interior axle, the bearing between outer tube and interior axle.
Last further improvements of the present utility model are: an end of drive screw is connected with and is used to control seat lift in height rocking handle.
The beneficial effects of the utility model:
1. utilize the morphotropism of rhombus and the self-lock mechanism of screw thread, lifting is convenient.
2. simple in structure, easily manufactured, with low cost, suitable applying.
(4) description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is a structural representation of the present utility model.
1 seat among the figure, 2 chair back, 3 drive screws, 4 lifting rocking handles, 5 rhombus framves, 6 whirligigs, 7 chair foot supports, 8 nuts, 9 outer tubes, 10 interior axles, 11 bearings.
(5) specific embodiment
A kind of mechanical elevating swivel chair as shown in Figure 1 comprises seat 1, the chair back 2, chair foot support 7 and lowering or hoisting gear, and described chair foot support 7 tops are provided with whirligig; Described lowering or hoisting gear lower end is connected with whirligig, and the upper end is connected with seat 1.
Described lowering or hoisting gear comprises and is provided with right-and-left threaded drive screw 3, is sleeved on the nut 8 at drive screw 3 two ends, rhombus frame 5, and the two ends, the left and right sides of described rhombus frame 5 are hinged on the nut 8, and the lower end is hinged on the whirligig, and the upper end is hinged on the seat 1.
Described whirligig comprises outer tube 9, interior axle 10, the bearing 11 between outer tube 9 and interior axle 10.
One end of drive screw 3 is connected with and is used to control seat lift in height rocking handle 4.
Rhombus frame 5 is formed by connecting by four identical short frame symmetries during manufacturing, and tie point adopts revolute pair.Drive screw 3 is that a centre is with the rigidity straight-bar that screw thread, two ends are provided with nut 8, and the nut 8 at two ends plays the effect of control screw stroke.The right half part of drive screw is the forward screw thread, and left-half is a reverse thread, and the short frame of the top of rhombus frame 5 links to each other with seat 1, and following short frame links to each other with whirligig 6, and nut 8 inside in the left and right sides all are provided with the forward screw thread.
Shake lifting handle 4 during use, drive screw 3 can rotate thereupon, because the morphotropism of rhombus, left and right sides nut 8 can be drawn close toward the centre or disperse to both sides under external force, and pallet can move up or down up and down, the liter of realizing seat with fall.
