Detailed Description

In order to make the technical means, creation features, achievement purposes and functions of the present invention easy to understand, the present invention is further described below with reference to the following embodiments.

As shown in fig. 1-3, a chair convenient for storage includes a seat plate 1, an adjusting mechanism 7 is disposed at a lower end of the seat plate 1, the adjusting mechanism 7 includes a fixing frame 71 fixedly disposed at the lower end of the seat plate 1, a rotating shaft 72 is movably disposed at an inner side of the fixing frame 71, a worm 73 is fixedly disposed at one side of an outer side of the rotating shaft 72, which is close to the fixing frame 71, a worm gear 74 is engaged with a lower end of the worm gear 73, a movable shaft 75 is fixedly disposed at an inner side of the worm gear 74, a support leg 76 is fixedly disposed at a lower end of the worm gear 74, a connecting frame 77 is movably disposed at an outer side of the support leg 76, a connecting shaft 78 is fixedly disposed inside the support leg 76, and a support bottom plate 79 is fixedly disposed at a lower end of the connecting frame 77.

In this embodiment, the mounting frame 710 is movably disposed at the outer side of the movable shaft 75 close to the rear side of the turbine 74, the knob 711 is fixedly disposed at one end of the rotating shaft 72, the connecting shaft 78 extends into the connecting frame 77, the connecting shaft 78 is movably connected with the connecting frame 77, the upper end of the mounting frame 710 is fixedly connected with the lower end of the seat plate 1 close to the rear side of the fixing frame 71, two sets of adjusting mechanisms 7 are provided, and two sets of adjusting mechanisms 7 are in central symmetry.

Specifically, firstly, the knob 711 is rotated, and the knob 711 drives the worm 73 to rotate through the rotating shaft 72, because the worm 73 is in meshed connection with the worm wheel 74, the worm 73 drives the worm wheel 74 to rotate around the movable shaft 75, meanwhile, the movable shaft 75 drives the supporting leg 76 to rotate, so that the included angle between the supporting leg 76 and the seat plate 1 is changed, at this time, the seat plate 1 is moved to a specified position, and the supporting base plate 79 is under the action of gravity, so that the supporting base plate 79 drives the connecting frame 77 to rotate around the connecting shaft 78, and the supporting base plate 79 is always parallel to the ground, and then the seat plate 1 is put down, so that the supporting base plate 79 is in contact with the ground, because the included angle between the supporting leg 76 and the seat plate 1 is changed, so that the height between the seat plate 1 and the ground is reduced, and the base plate is convenient for children to use, the rotating shaft 72 is rotated so that the rotating shaft 72 drives the worm 73 to rotate and the worm wheel 73 drives the worm wheel 74 to rotate, so that the worm wheel 74 drives the supporting leg 76 to rotate, and the purpose of changing the included angle between the supporting leg 76 and the seat plate 76 can be convenient for children to use.

In this embodiment, the lower extreme of bedplate 1 is close to the fixed bracing piece 2 that is provided with in front end of mount 71, and the restriction groove has been seted up to the lower extreme of bracing piece 2, and the front end of bracing piece 2 is provided with connecting rod 3 through the pivot activity, and the front end of connecting rod 3 is provided with dead lever 4 through the pivot activity, and the one end of dead lever 4 is fixed and is provided with back 5, and the rear end of dead lever 4 is close to the fixed restriction bar 6 that is provided with of downside of connecting rod 3, the outside and the restriction groove swing joint of restriction bar 6.

Specifically, thereby make bedplate 1 drive bracing piece 2 and remove simultaneously backrest 5 to the one side removal that is close to bedplate 1 and drive dead lever 4 and remove thereby making restriction lever 6 break away from the restriction slot of 2 lower extremes of bracing piece through inside pulling bedplate 1 and backrest 5, can reach the purpose of being convenient for to accomodate.

The working principle is as follows:

during the use, the user at first pulls open bedplate 1 and back 5, thereby make bedplate 1 drive bracing piece 2 and remove, back 5 drives dead lever 4 and removes, and make dead lever 4, connecting rod 3, form the triangle-shaped between the bracing piece 2, and dead lever 4 drives restriction lever 6 card in the restriction inslot of bracing piece 2 lower extreme, thereby accomplish the equipment of chair, at this moment turn knob 711, and make knob 711 drive worm 73 through axis of rotation 72 and rotate, because be meshing connection between worm 73 and the turbine 74, worm 73 drives turbine 74 and uses movable shaft 75 as the hub rotation, movable shaft 75 drives supporting leg 76 rotatory simultaneously, thereby make the contained angle between supporting leg 76 and bedplate 1 change, at this moment carry bedplate 1 to assigned position department again, and supporting bottom plate 79 is under the effect of gravity, make supporting bottom plate 79 drive connecting axle 77 and use connecting axle 78 as the hub rotation, and make supporting bottom plate 79 be parallel to the ground all the time, then just put down with bedplate 1, thereby make supporting bottom plate 79 contact with ground, because change the contained angle between axis of rotation 76 and the base plate 1, thereby make the height between axis of rotation 1 and the ground diminish in convenience for use, and make children drive worm support leg 74 and rotate through worm 73, thereby make children's worm drive supporting leg 76 and rotate the purpose of worm 76, thereby make children convenient for use.

The foregoing shows and describes the basic principles and principal features of the invention, together with the advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
