Specific embodiment

In order to enable those skilled in the art to better understand the technical solutions of the present invention, with reference to the accompanying drawing to this reality Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the protection scope of the utility model There is any restriction effect.

As shown in Fig. 1-Fig. 7, the specific structure of the utility model are as follows: a kind of convertible double-purpose seat, including seat 1 and help Hand 2, the seat 1 include seat board 15 and backup plate 14, and the seat board 15 is arranged with backup plate 14 at H type, 15 two sides of seat board It is symmetrically arranged with connecting shaft 11, the handrail 2 for being used to support seat, 2 bottom of handrail are hinged in two connecting shafts 11 Hold level with both hands and put it on the ground, the backup plate 14 can rotate to be desktop around connecting shaft 11；Arc panel is just provided below in the seat board 15 3,3 two sides of arc panel are fixed by screws on handrail 2, the arc panel 3 among the end face of 15 side of seat board along arc Face bending direction is provided with the arc groove 35 that section is convex, and the setting in the middle part of 16 end face of riser of shank is used on the seat board 15 There is the protrusion 13 rotated in the small arc slot 351 of arc groove 35, being connected on described raised 13 can pull seat board 15 around connecting shaft The rope 34 of 11 rotations, the rope 34 are arranged in the big arc slot 352 on arc groove 35, from 35 end of arc groove outlet 36 It after extraction and is wrapped in and is arranged on arc panel 3 close on the turntable 32 at backup plate 14,32 axis of turntable is hinged on arc panel 3 On bracket 37 on and by direct current generator 31 drive rotation.

Preferably, the seat 1 its center of gravity when rotating around connecting shaft 11 is being biased to 14 side of backup plate.When reset, backup plate 14 It can decline by gravity, and slow whereabouts is drawn by rope 34.

Preferably, two vertical slots 12 are provided on 16 lateral surface of riser, the vertical slot 12 is in riser 16 around connecting shaft 11 Agree at 90 degree of rotation with two baffles 33 being arranged in 3 cambered surface of arc panel.At 90 degree of rotation, baffle 33 blocks perpendicular riser 16 Plate prevents it because of other external forces, continues to rotate, and keeps it more steady.

Preferably, the width of the small arc slot 351 is less than the diameter of rope 34, so that rope 34 is along the big of arc groove 35 Arc slot 352 is mobile, is unlikely to fall off, and cannot be stuck in small arc slot 351.

Specific embodiment: when needing chair being converted to desk, direct current generator 31, direct current are started by outer button Motor 31 controls turnning circle by single-chip microcontroller, it drives turntable 32 to rotate, and turntable 32 starts wiring, due to one end of rope 34 The protrusion 13 of 16 lower end of riser is connected, and rope 34 is arranged in the big arc slot 352 of arc groove 35, therefore rope 34 arcuately transport by slot It is dynamic, and the small arc slot 351 of the arcuately slot 35 of sync pulling riser 16 is mobile, when being moved at baffle 33, baffle 33 and vertical slot 12 inner face completely attaches to, and turntable 32 stops operating under the control of single-chip microcontroller, and 31 power loss of direct current generator is lockked.When needing to be reset When, outer button is pressed, so that direct current generator 31 inverts, seat 1, therefore can be under automatic turning since center of gravity is at backup plate 14, rope The slowly decline of 34 traction chairs 1, prevents its falling speed too fast, when 14 end face of backup plate when being contacted with ground, direct current generator 31 loses Electricity, and lock in the position, it realizes and resets.

It should be noted that, in this document, the terms "include", "comprise" or its any other variant are intended to non-row His property includes, so that the process, method, article or equipment for including a series of elements not only includes those elements, and And further include other elements that are not explicitly listed, or further include for this process, method, article or equipment institute it is intrinsic Element.
