Abstract

The utility model discloses a low lying rotating body protection seat, which is mounted with auger gears on the rotating chair shaft to joggle connected with bradawl gears mounted on the box body shaft, wherein the bradawl gears are connected with a paddle by a communicating device, one end of the supporting rod is hinge jointed with back end of the box body, the other end of the supporting rod is hinge jointed with side of the back. The utility model employs rotating centrifugal force to supply blood to the brain without real headstand. One can only lie low to realize headstand body protection effect, which is safer. The abnormal appliance on normal device makes the structure simple and operation convenient and one can adjust the comfort level by himself. The utility model is low in cost and creates better body building condition for consumers and achieves more economic consuming target.

Description

A kind of rotation ab lounge that lies low

Technical field

The utility model relates to revolvable chair, especially relates to a kind of rotation ab lounge that lies low.

Background technology

The handstand body-building method is a kind of recreation that a lot of young men like, and also is one of best mode of young man's body-building.Monkey show before more than 1,000 year in Huatuo's the five-animal exercises just has the action of handstand, and handstand more helps the raising of people's intelligence and respond, because handstand can increase the domination sensing ability under cerebrum blood supply and the various condition.General handstand action is that human body is turned around, head down, this method is relatively more dangerous, it is little to be fit to crowd's scope.Patent 96251963.4 discloses a kind of seat and has crouched turning chair by various transmission mechanisms, and worm and gear etc. is arranged, the cost height, and train is many, and the bar group is many, and complex structure has only been realized setting level of chair.Patent 02222472.6 discloses a kind of multifunctional rotary swivel chair and has adopted alignment pin, locating hole to realize turning to the location, and turns at random.When the calibration that requires to locate hour, will make the pipe pillar be broken into two sections, lose meaning.

Summary of the invention

The purpose of this utility model is to provide a kind of rotation ab lounge that lies low, and not only seat support has spinfunction but also backrest can be set level.

The technical scheme that its technical problem that solves the utility model adopts is:

Comprise and be hinged with backrest on seat support, the seat support, a ratchet retaining mechanism is arranged in the hinged place, seat support is enclosed within on the column of leg by following tube shape bulge, thrust bearing is housed on the contact plane, seat support rotates on the leg column, also is connected with handrail and ribbed insert by pin between seat support and the backrest.Also fixedly connected casing below the seat support, on the leg column bevel gear wheel is housed, with the bevel pinion engagement that is contained on the casing minor axis, on the axle of casing middle part driven sprocket is housed, on the anterior driving shaft of casing drive sprocket is housed, both ends of main drive shaft is equipped with pedal through treadle respectively, and driven sprocket is connected transmission with drive sprocket with chain, is exposed at driven gear and the driving gear engagement that is exposed on the axle of the outer middle part of casing on the outer minor axis of casing; One end and the box back face of support link are hinged, and an end of the other end of support link and supplemental support pin is hinged, and the other end of supplemental support pin and backrest trailing flank are hinged.

The beneficial effect that the utlity model has is: utilize the rotary centrifugal force principle to promote brain blood supply, there is not real action of standing upside down, and only need human body to lie low, realize the effect of handstand body-building, safer, the anti-convention application of the conventional mechanism that proposes makes simple in structure, easy to operate, can oneself regulate comfort level.And cost is lower, for the consumer has created better body-building condition, more economical consumption target.

Among the figure: 1. backrest; 2. supplemental support pin; 3. support link; 4. handrail; 5. ribbed insert; 6. seat support; 7. leg; 8. treadle; 9. pedal; 10. casing; 11. bevel gear wheel; 12 bevel pinions; 13. driven sprocket; 14. chain; 15. drive sprocket; 16. axle; 17. active spur gear; 18. driven gear; 19. minor axis; 20. ratchet retaining mechanism.

The specific embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

As Fig. 1, Fig. 2, shown in Figure 3, the utility model comprises by backrest 1, supplemental support pin 2, support link 3, handrail 4, ribbed insert 5, seat support 6, leg 7, treadle 8, pedal 9, casing 10, bevel gear wheel 11, bevel pinion 12, driven sprocket 13, chain 14, drive sprocket 15, axle 16, active spur gear 17, driven gear 18, minor axis 19 and ratchet retaining mechanism 20 constitute (omit fastening connection piece, bearing, reach the related process structure).

Seat support 6 is enclosed within by following tube shape bulge on the column of leg 7, connects the plane thrust bearing is housed, and seat support 6 can rotate on leg 7; Be connected with backrest 1 by pin on the seat support 6, also be connected with handrail 4 and ribbed insert 5 between seat support 6 and the backrest 1 by pin, handrail 4 also is that pin is connected with ribbed insert 5, and seat support 6, backrest 1, handrail 4 and ribbed insert 5 form a parallelogram connection-rod structure (as ABCD among Fig. 4); Also fixedly connected casing 10 below the seat support 6; Above the casing 10 transmission mechanism is arranged, transmission mechanism is made up of chain gear transmission, spur gear transmission and Bevel Gear Transmission, power is by pedal 9, treadle 8, drive sprocket 15 passes to by movable sprocket 13 by chain 14 again, connect driven gear 13 and active spur gear 17 by axle 16 again, power passes to driven spur gear 18 from the active spur gear again, and minor axis 19 is connecting driven spur gear 18 and bevel pinion 12, and bevel gear wheel 11 is fixed together with leg 7.

The junction of seat support 6 and backrest 1 also has a ratchet retaining mechanism 20.

Backrest 1, supplemental support pin 2, support link 3 and casing 10 have constituted another parallelogram connection-rod structure (as DEFG among Fig. 4).Since among the parallelogram ABCD among CD limit and the parallelogram DEFG DG limit coexist on the backrest, so parallelogram ABCD and parallelogram DEFG have formed the parallelogram of two series connection.And, make limit DE perpendicular to ground, thereby make supplemental support pin 2 all the time perpendicular to ground through design.

The people is sitting on the seat support 6, loosen the ratchet retaining mechanism, slowly lie down, as shown in Figure 4, by seat support 6, backrest 1, handrail 4 and ribbed insert 5 form a parallelogram connection-rod structure ABCD, by backrest 1, supplemental support pin 2, support link 3 and casing 10 have constituted another parallelogram connection-rod structure DEFG, the series connection of two parallelogram, so when backrest puts down, supplemental support pin 2 descends automatically, until supplemental support pin 2 kiss the earths, at this moment the people lies flat (as shown in Figure 5) substantially, the human pin is trampled pedal 9, make drive sprocket 15 rotations by treadle 8, pass to by movable sprocket 13 by chain 14, connect driven gear 13 and active spur gear 17 by axle 16 again, power passes to driven spur gear 18 from the active spur gear again, minor axis 19 is connecting driven spur gear 18 and bevel pinion 12, because bevel gear wheel 11 is fixed together with leg 7, casing 10 is fixed together with seat support 6, the people is sitting on the seat support 6, for Bevel Gear Transmission mechanism, is equivalent to bevel gear wheel 11 is used as " frame ", power source is on casing, bevel pinion is on casing, so the input of the power of bevel pinion 12 will produce motion output from casing, (be that cone pulley mechanism is anticaustic, fix with big cone pulley, power source is on frame, and power inputs to little cone pulley, because motion relativity, to rotatablely move from frame output), thus make the human body that lies on the chair do rotation around leg 7 centers, and make head and upper body slightly downward-sloping, in rotary course, blood of human body is formed centrifugal force, increase brain blood supply, realized the effect of handstand body-building, and more safe and effective.
