It is vertically fixedly mounted on the bottom surface of the seat board 110 there are two support rod, the lower end of each support rod is distinguished It is rotatably equipped with a main wheel 111, two main wheels 111 are located at the two sides of the seat board 110, and two main wheels 111 mutually back to side on be respectively and fixedly provided with a circle rubber ring, convenient for when being used as wheelchair patient's automatic moving use. The two edges of 110 top surface of seat board are fixedly installed with a vertical handrail 112 respectively, can play protective action, avoid Patient surprisingly falls.In the present embodiment, the handrail 112 is stretching structure, can be used to protect patient after shortening, can after elongation It is used on handrail 112 as device of walking aid so that patient's both hands are helped, patient is allowed slowly to rely on the device walking to be promoted Physical recovery speed.

A upright bar 121 is vertically and fixedly provided on the bottom surface of the leg plate 120, and the top of the upright bar 121 is located at the leg On the central axes of plate 120, the bottom end of the upright bar 121 is rotatably equipped with the first directive wheel 122, and first directive wheel 122 is not But it plays a supportive role, and direction of advance can be controlled.First directive wheel, 122 bottom end to the leg plate 120 distance with 111 bottom end of main wheel being equidistant to the seat board 110, thus when being used as hospital bed described in 122 He of the first directive wheel Main wheel 111 is able to maintain the backboard 100, seat board 110 and leg plate 120 and is in horizontality.

The leg plate 120 is rotatably equipped at least one second directive wheel 123 in one end far from the seat board 110, this Normal use when in embodiment in order to not influence as hospital bed, second directive wheel 123 are mounted on 120 bottom surface of leg plate Upper one end far from the seat board 110.

It is rotatably equipped with the first pull rod 101 on the side of the backboard 100, is rotatablely installed on the side of the leg plate 120 There is the second pull rod 124, control box 113 is rotatably equipped on the side of the seat board 110, one end of first pull rod 101 turns Dynamic to be connected on the side of backboard 100, the other end is inserted into the control box 113, one end rotation of second pull rod 124 It is connected on the side of leg plate 120, the other end is inserted into the control box 113, first pull rod 101 and the second pull rod 124 are parallel to each other, and can slide in the control box 113.

Referring to Fig. 3 and Fig. 4, parallel sliding slot there are two tools inside the control box 113, and two sliding slots run through institute State the side wall of control box 113.113 center of inside of control box is also provided with a swivelling chute, which is located at two institutes It states between sliding slot, and two sliding slot connections is got up.Gear 114 is rotatably equipped in the swivelling chute, described first draws Bar 101 and the second pull rod 124, which are inserted on the part of the control box 113, has rack gear, the gear 114 and first pull rod 101 and the second rack gear on pull rod 124 engage so that first pull rod 101 and the second pull rod 124 are in the gear 114 Drive under simultaneously move in the opposite direction.

In order to be fixed the backboard 100 and leg plate 120 can after 90 degree of rotation, on the control box 113 also Bolt 115 is installed, the control box 113 offers at least one jack on the side back to the seat board 110, described to insert There is inserted link identical with the jack quantity, the inserted link one-to-one correspondence on the bolt 115 is inserted into the control on pin 115 In jack on box 113 and protrude into inside the control box 113.The gear 114 is opened up in position corresponding with the jack There is at least one limit hole, when needing to fix the angle of the backboard 100 and leg plate 120, it is only necessary to press the bolt 115 Under, the inserted link on bolt 115 is inserted into the limit hole on the gear 114, can lock the gear 114, and described at this time As soon as pull rod 101 and the second pull rod 124 are fixed, the angle of backboard 100 and leg plate 124 is also fixed.

Certainly, for the safety in use process, protection can be set on first pull rod 101 and the second pull rod 124 Set, avoids causing patient to wound in use process.

When first pull rod 101 is in the state parallel with the backboard 100, due to 101 He of the first pull rod Second pull rod 124 is parallel, therefore the backboard 100, seat board 110 and leg plate 120 are in same level, the first directive wheel 122 and main wheel 111 play a supporting role jointly, pressing bolt 115 can be such that backboard 100 and leg plate 120 is fixed, at this time institute Multifunctional chair is stated to use as hospital bed.It needs as wheelchair in use, first pulling up bolt 115 to come, upwards by the backboard 100 Rotation or leg plate 120 rotate down, and first pull rod 101 or the second pull rod 124 also rotate with it, when backboard 100 and leg When plate 120 is vertical with seat board 110, backboard 100 and leg plate 120 can be fixed by pressing bolt 115.Second directive wheel at this time 123 and main wheel 111 play a supporting role simultaneously, and the first directive wheel 122 is then received between two main wheels 111, will not be to making With impacting.

Disclosed above is only several specific embodiments of the invention, and still, the embodiment of the present invention is not limited to this, is appointed What what those skilled in the art can think variation should all fall into protection scope of the present invention.
