Abstract
The utility model provides a kind of lift swivel chair, comprises the chair back, seat support, pedestal; Fix a bearing below described seat support, described bearing shaft is connected to a screw rod extended straight down; Described pedestal upwards extends a screwed pipe, described screwed pipe has the internal thread matched with described screw rod; Described screw rod is hollow stem, and the lower end of the upper end of its hollow interior and the hollow interior of described screwed pipe links a rigidity rope; Described bearing is also equipped with bearing locking mechanism.This lift swivel chair not only can rotate freely, be elevated, and has abandoned cylinder, gets rid of potential safety hazard.
Description
Technical field
The utility model relates to life field of sanitary equipment, especially, relates to a kind of lift swivel chair.
Background technology
Lift swivel chair is life and a kind of seat common in handling official business, and it not only can rotate freely, and can regulate upper-lower height.For current lift swivel chair, main employing cylinder type lifting governor motion, its subject matter existed is, there is larger potential safety hazard in cylinder, when seat acutely rocks, and the easy explosion of cylinder, cause piston rod to fling seat support, very likely through seat support, huge injury is caused to human body.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of lift swivel chair, and this lift swivel chair not only can rotate freely, be elevated, and has abandoned cylinder, gets rid of potential safety hazard.
The utility model solves the technical scheme that its technical problem adopts: this lift swivel chair comprises the chair back, seat support, pedestal; Fix a bearing below described seat support, described bearing shaft is connected to a screw rod extended straight down; Described pedestal upwards extends a screwed pipe, described screwed pipe has the internal thread matched with described screw rod; Described screw rod is hollow stem, and the lower end of the upper end of its hollow interior and the hollow interior of described screwed pipe links a rigidity rope; Described bearing is also equipped with bearing locking mechanism.
As preferably, described bearing locking mechanism comprise end face smooth, the nut that matches with described screw rod; When described nut rotates and rises to extreme position on described screw rod, its end face compresses inner ring and the outer ring of described bearing; Described nut side direction fixes a driving lever extended along nut radial direction.
As preferably, described rigidity rope is made up of metallic bond, in seat support decline process, vertically can drop, and can not occur significantly that side direction is curling, avoids the screw thread pair blocked between screwed pipe and screw rod.
The beneficial effects of the utility model are: under the state that this lift swivel chair unclamps at described bearing locking mechanism, when user is sitting in and rotates above seat support, due under weight, screw thread pair between screwed pipe and screw rod bears larger contact, so rotate frictional resistance much larger than the rotation frictional resistance between the inner ring and outer ring of described bearing, so now seat support carries human body and rotates freely, and substantially static between screw rod and screwed pipe, seat support does not produce lifting; And when needs lifting seat support, only need by locked for described bearing, when then user rotates seat support, screw rod rotates in screwed pipe, thus realizes rising or the decline of seat support, and, by the restriction of described rigidity rope, the limit lifting position of screw rod can be limited, prevent it from deviating from above screwed pipe, and not affecting the decline of screw rod, structure is extremely simple; Cylinder abandoned by this lift swivel chair, and eliminate potential safety hazard, and structure is more simple, cost is lower.
Accompanying drawing explanation
Fig. 1 is an embodiment schematic diagram of this lift swivel chair.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated:
In the embodiment shown in fig. 1, this lift swivel chair comprises the chair back 1, seat support 2, pedestal 5; Fix a bearing 3 below described seat support 2, described bearing 3 is coupling the screw rod 4 that Yu Yigen extends straight down; Described pedestal 5 upwards extends a screwed pipe 51, described screwed pipe 51 has the internal thread matched with described screw rod 4; Described screw rod 4 is hollow stem, and the lower end of the upper end of its hollow interior and the hollow interior of described screwed pipe 51 links a rigidity rope 7; Described bearing 3 is also equipped with bearing locking mechanism.
Above-mentioned lift swivel chair, described bearing locking mechanism comprise end face smooth, the nut 6 that matches with described screw rod 4; When described nut 6 rotates and rises to extreme position on described screw rod, its end face compresses inner ring and the outer ring of described bearing 3, by stiction, is increased sharply by the rotation frictional resistance between inner ring and outer ring; Described nut 6 side direction fixes a driving lever 61 extended along nut radial direction.
Above-mentioned lift swivel chair, described rigidity rope 7 is made up of metallic bond, in seat support 2 decline process, vertically can drop, and can not occur significantly that side direction is curling, avoids blocking the screw thread pair between screwed pipe 51 and screw rod 4.
Under the state that above-mentioned lift swivel chair unclamps at bearing locking mechanism, when user is sitting in and rotates above seat support 2, due under weight, screw thread pair between screwed pipe 51 and screw rod 4 bears larger contact, so rotate frictional resistance much larger than the rotation frictional resistance between the inner ring and outer ring of described bearing 3, so now seat support carries human body and rotates freely, and substantially static between screw rod 4 and screwed pipe 51, seat support 2 does not produce lifting; And when needs lifting seat support 2, only need by locked for described bearing 3, when then user rotates seat support, screw rod rotates in screwed pipe, thus realizes rising or the decline of seat support, and, by the restriction of described rigidity rope 7, the limit lifting position of screw rod 4 can be limited, prevent it from deviating from above screwed pipe 51, and not affecting the decline of screw rod 4, structure is extremely simple; And regulate switch swivel chair rotating freely or oscilaltion function time, only described driving lever 61 need be stirred a less angle can realize; Cylinder abandoned by this lift swivel chair, and eliminate potential safety hazard, and structure is more simple, cost is lower.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
