Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-5, the present invention provides a technical solution:

the first embodiment is as follows:

the utility model provides a multi-functional rotatable chair, which comprises a base 1, 1 up end middle part fixedly connected with sliding sleeve 4 on chassis, the even fixedly connected with supporting legs in terminal surface middle part 2 under chassis 1, cavity wall sliding connection has traveller 5 in sliding sleeve 4, the even fixedly connected with tooth piece 6 in the traveller 5 right side, the traveller 5 up end rotates and is connected with sponge cushion 11, the equal fixedly connected with turning block 26 in the 11 rear end face left and right sides of sponge cushion, the inside rotation of turning block 26 is connected with dwang 25, the outside left side fixedly connected with back 23 of dwang 25, dwang 25 left end face fixedly connected with adjusting gear 22, 11 left end face rear sides of sponge cushion are equipped with first spout 14, rear end face fixedly connected with slide bar 18 before first spout 14, the outside sliding connection of slide bar 18 has first slider 17, the inside elastic net 24 that is equipped with of back 23. The upper end face right side fixedly connected with connecting plate 8 on chassis 1, the 8 rear end face upsides of connecting plate pass through mount pad 9 fixedly connected with motor 10, and motor 10 output end fixedly connected with owner changes gear 7, and the meshing of owner commentaries on classics gear 7 is connected with tooth piece 6. The motor 10 drives the main rotating gear 7 to rotate, and the main rotating gear 7 drives the sliding column 5 to ascend or descend through the gear block 6, so that the height of the chair can be adjusted more conveniently. First slider 17 sliding connection has first spout 14, first spout 14 lower extreme is equipped with second spout 15, the inside sliding connection of second spout 15 has second slider 16, the first slider 17 of second slider 16 up end fixedly connected with, the outside cover of slide bar 18 is equipped with first pressure spring 19, first pressure spring 19 front end fixedly connected with first slider 17, first pressure spring 19 rear end fixedly connected with first spout 14, first slider 17 left end fixedly connected with fixed column 20, fixed column 20 left end fixedly connected with block gear 21, block gear 21 meshing is connected with adjusting gear 22. Through the manual pulling forward of block gear 21, first slider 17 extrudees first pressure spring 19, and first slider 17 and second slider 16 slide in first spout 14 and second spout 15 respectively, make block gear 21 keep away from adjusting gear 22, as required, rotate back 23, after the adjustment is accomplished, loosen block gear 21, block gear 21 position recovers, accomplish the block with adjusting gear 22 once more, can accomplish the fixed of back 23 position to more conveniently adjust the angle of back 23.

Example two: the difference between the present embodiment and the first embodiment is that the middle portions of the left and right end surfaces of the sponge cushion 11 are both fixedly connected with a fixing rod 12, and the upper end surface of the fixing rod 12 is fixedly connected with a handrail 13. The anterior left side sliding connection in chassis 1 has flexible post 28, and flexible post 28 up end fixedly connected with footboard 27, the outside cover of flexible post 28 are equipped with second pressure spring 29, and terminal surface fixedly connected with second pressure spring 29 under footboard 27, second pressure spring 29 lower extreme fixedly connected with chassis 1, terminal surface fixedly connected with silica gel pad 30 under the flexible post 28. By stepping on the pedal 27, the pedal 27 moves downwards and presses the second pressure spring 29, and the telescopic column 28 moves downwards until the silica gel pad 30 contacts the ground, so that the friction force between the whole chair and the ground is increased, and the emergency braking effect is more conveniently realized in the moving process. The lower ends of the supporting legs 2 are provided with universal wheels 3.

When the chair works, firstly, the motor 10 is started as required, the motor 10 drives the main rotating gear 7 to rotate, the main rotating gear 7 drives the sliding column 5 to ascend or descend through the tooth block 6 and adjust to a proper position, then the clamping gear 21 is pulled forward manually, the first sliding block 17 extrudes the first pressure spring 19, the first sliding block 17 and the second sliding block 16 respectively slide in the first sliding chute 14 and the second sliding chute 15 to enable the clamping gear 21 to be far away from the adjusting gear 22, the backrest 23 is rotated as required, after the adjustment is completed, the clamping gear 21 is released, the position of the clamping gear 21 is restored, the clamping with the adjusting gear 22 is completed again, the position fixing of the backrest 23 can be completed, when a person sits on the chair to move, the person can pedal 27 can be used for stepping on the pedal 27 to move downwards and extrude the second pressure spring 29, the telescopic column 28 moves downwards until the silica gel pad 30 contacts the ground, and the whole friction force with the ground is increased, and (5) completing braking. The whole device drives the main rotating gear 7 to rotate through the motor 10, and the main rotating gear 7 drives the sliding column 5 to ascend or descend through the tooth block 6, so that the height of the chair can be adjusted more conveniently. Through the manual pulling forward of block gear 21, first slider 17 extrudees first pressure spring 19, and first slider 17 and second slider 16 slide in first spout 14 and second spout 15 respectively, make block gear 21 keep away from adjusting gear 22, as required, rotate back 23, after the adjustment is accomplished, loosen block gear 21, block gear 21 position recovers, accomplish the block with adjusting gear 22 once more, can accomplish the fixed of back 23 position to more conveniently adjust the angle of back 23. By stepping on the pedal 27, the pedal 27 moves downwards and presses the second pressure spring 29, and the telescopic column 28 moves downwards until the silica gel pad 30 contacts the ground, so that the friction force between the whole chair and the ground is increased, and the emergency braking effect is more conveniently realized in the moving process.
