Abstract

The utility model relates to a rotary bookshelf. When an actuating switch 31 and an actuating switch 32 are actuated, a speed reducing motor 29 starts, and a rotary board 1 rotates, a bookshelf 20 is supported by a pin 13 which rotates with a board 1. Because a pin 16 moves along the annular groove 24 of a quiescence board 21, the center of the bookshelf is always kept on a vertical direction by making a board 6 rotate around the shaft, the bookshelf can keep horizontal balance at the time of rotating, and therefore, people can sit and put and take books on a higher position of the bookshelf by pulling the bookshelf down. Because the pin 16 is inserted in the annular groove 24 of a board 21, consequently the bookshelf can not slope under the situation that the weight of the left side of the bookshelf is unequal to the weight of the right side of the bookshelf.

Be a kind of rotary book shelf of realizing that above-mentioned purpose of the present utility model proposes, this bookshelf comprises:

A reducing motor that is installed on the support plate that is positioned at below the supporting station, actuation switch is equipped with in front at this supporting station, one is contained in pinion on the axle by the hole, steadying plate with a hole and a bearing, a cannelure is arranged on the front of this plate, a groove is arranged at its top, the support arm of this steadying plate is vertically mounted on this supporting station, the described support arm that this steadying plate has is in its two ends and forms a space, the center in this space is corresponding with the center of this pinion, 4 supports are fixed on the supporting station, a hole is positioned at the center of rotor plate, the hole forms on all directions of this plate, semi-circular groove and jaw form on the periphery in this hole, ring gear forms at the periphery place of the back of this plate, this rotor plate has a plurality of rubber supporting legs that are contained on this plate, this ring gear is meshed with this pinion, an axle has a jaw, keyway and screw hole, by using a locating snap ring, key and bolt are connected to each other these parts, rotor plate has along three directions and inserts the roller in this hole, the cover plate that is formed with semi-circular groove is tight by bolted cover, two faces of this roller all contact with half of corresponding hole and semi-circular groove, separating part forms on described rotor plate, pin with described jaw and keyway inserts the central authorities of this plate and passes between the roller of this separating part and this plate, described pin inserts in the hole of bookshelf by the mode of this pin being inserted the cannelure of this plate, therefore, by this key and locating snap ring, this bookshelf can be fixed, this bookshelf is supported by this pin, when this rotor plate being rotated by operation actuation switch start and deceleration motor, this bookshelf is supported by this pin that rotates with this plate, because this downside pin moves along the cannelure of this steadying plate, by making plate the center of this bookshelf always be remained on the vertical direction around its rotation, so this bookshelf can keep horizontal equilibrium when rotated, therefore, by bookshelf is pulled down, people can be in sitting posture and can put book and get book on the higher position of bookshelf; Because pin is inserted in this cannelure of this plate, even thereby this bookshelf under the unequal situation of the weight of the left and right sides, can not tilt yet.

The accompanying drawing that is comprised is used for the utility model is provided further understanding and is combined in its part of present specification formation, and this accompanying drawing is used for illustrating embodiment of the present utility model and is used for illustrating principle of the present utility model with this explanation.Wherein:

Fig. 1 is a perspective view of the present utility model;

Fig. 2 and 3 is the perspective views after the utility model decomposes;

Fig. 4 is a cutaway view of the present utility model;

Fig. 5 is the amplification view that blocks of the present utility model.

To introduce most preferred embodiment of the present utility model in detail below, the example is shown in the drawings.

When operation is used for selected clockwise or

counterclockwise actuation switch

31,32 o'clock, reducing motor just is driven, and pinion is rotated, and rotor plate 1 just orders about it by the ring gear 12 that is meshed with it and rotates along some directions.When rotor plate 1 rotated, bookshelf itself just rotated along the rotation direction identical with plate 1.

When book is not placed on the bookshelf, when bookshelf rotated, by the supporting of pin 13, himself will keep level.

But, because rotary book shelf is placed with book with the left side of its guide center or right side or its on whole, losing under the situation of its weight balancing at it, bookshelf is understood naturally to its right side or left side.Therefore, bookshelf also is not ready for reaching the good operation condition, because it is unsettled and inaesthetic.

Therefore, the utility model is intended to address the above problem, that is to say that even be under the unequal situation of left and right sides counterpoise, structure and the pin 16 that be inserted in bookshelf bottom of the utility model by the cannelure 24 of steadying plate 21 remains in level when bookshelf is rotated.

That is to say that under the situation of bookshelf motion, rotor plate 1 changes 360, pin 16 also rotates 360 °.

It is corresponding with the cannelure 24 of steadying plate 21 that pin 16 rotates a formed track of circle (not putting under the situation of book on the shelf).

Therefore, because the vertical centre of

last downside pin

13,16 is arranged on the vertical line, the cannelure 24 along steadying plate 21 moves simultaneously, just can force this bookshelf to keep level.

Cause the reason of above-mentioned situation to be, pin 16 is inserted in the cannelure 24 of steadying plate 21, moves as annular trace along cannelure 24 simultaneously, and still, pin 16 can not move to the right side and the left side of cannelure 24 under its halted state.

Therefore, when

13,16 is arranged on the vertical line, make simultaneously pin 16 when rotor plate 1 rotates when the cannelure 24 of steadying plate 21 rotates, bookshelf can be kept be very important in the horizontal direction.Pin 16 makes bookshelf maintenance level along cannelure 24 rotations.When rotor plate 1 when the counter-clockwise direction of Fig. 1 is rotated, if the peak of bookshelf still is in original position after rotating a circle, pin 16 will rotate counterclockwise 360 ° along the cannelure 24 of steadying plate 21, on the contrary, separating part C is that benchmark has clockwise rotated 360 ° with rotor plate 6.

Cause the reason of above-mentioned situation to be, when pin 16 when cannelure 24 rotates in the counterclockwise direction, because bookshelf remains at horizontal level when counterclockwise rotating, at last, under the condition that pin 16 must move upward in separating part C clockwise, upper and

lower pin

13,16 just can remain on the vertical line.

Therefore, if plate 6 can not form rotation,

plate

1,6 formed separating part C just can not form rotation, and the utility model just can not be realized.At this moment, rotor plate 6 rotates 360 ° in the hole 2 of its axis at rotor plate 1.Because pin 16 moves between roller 7, thereby is retrained by roller.

As mentioned above, bookshelf of the present utility model can keep level in any position, be not subjected to the restriction of the motion relevant with the rotation of rotor plate 1, thereby it has and makes people be in the effect that sitting posture can be got book or put book on the bookshelf higher position.

In addition, the utility model also has a kind of industrial effect, promptly this rotary book shelf can be contained in and do that table is gone up and when the mode of the diameter by expansion rotor plate 1 is fixed thereon with a plurality of bookshelves, can deposit many books by put a support below at it; Can drive with manpower without reducing motor; And can be used as the Display frame of extensive stock, a kind of toy and a kind of industrial utensil to it and use, and be not limited to this purposes of bookshelf.
