Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

A bookcase convenient to move, as shown in fig. 1-3, comprising a bookcase body 1, wherein the bookcase body 1 comprises a base 2 and a book storage part 3 fixed at the top end of the base 2.

The base 2 is provided with a cavity 4 inside. The cavity 4 is internally provided with a lifting plate 5 and a driving structure for driving the lifting plate 5 to move up and down.

The top cavity wall of the cavity 4 is provided with a mounting groove. The left and right side cavity walls of the cavity 4 are provided with sliding grooves 22. Four openings 6 leading to the outside of the base 2 are arranged on the bottom cavity wall of the cavity 4.

The left and right ends of the lifting plate 5 are provided with second sliders 23 for being inserted into the slide grooves 22 and moving along the slide grooves 22. The top of lifter plate 5 is fixed with two installation pieces 7, fixedly connected with guide rail 8 between two installation pieces 7, and the outside slip cap of guide rail 8 is equipped with two first sliders 9. Four rollers 10 are fixed at the bottom end of the lifting plate 5, and the four rollers 10 correspond to the positions of the four openings 6 respectively.

The driving structure comprises a motor 11, a rotating shaft 12 and a lifting frame 13. The motor 11 is installed in the installation groove, and the output shaft of the motor is vertically downward and is fixed with a first bevel gear 14. The rotating shaft 12 comprises a first rotating rod 15, a first screw rod 16, an intermediate rod 17, a second screw rod 18 and a second rotating rod 19 from left to right in sequence. The ends of the first rotating rod 15 and the second rotating rod 19 which are far away from each other are respectively connected with the two side cavity walls of the cavity 4 in a rotating way. A second bevel gear 20 engaged with the first bevel gear 14 is fixed to the outer portion of the intermediate lever 17. The first screw mandrel 16 and the second screw mandrel 18 have opposite thread directions, and are sleeved with nut seats 21. Two sides of the top end of the lifting frame 13 are respectively hinged with the two nut seats 21, and two sides of the bottom end of the lifting frame 13 are respectively hinged with the two first sliding blocks 9.

Additionally, a ball groove is formed in the outer side wall of the second slider 23, a universal ball 24 is arranged in the ball groove, and one end of the universal ball 24 penetrates through the ball groove and is in rolling connection with the groove wall of the sliding groove 22. By providing the ball 24, the second slider 23 can move more smoothly in the slide groove 22.

The outer side wall of the bookcase body 1 is provided with a groove 26, and the size of the groove 26 is larger than that of a palm of a general adult. A handle 25 is provided in the recess 26. Handle 25 provides better impetus for the user, makes things convenient for user of service to stimulate book case body 1, and handle 25 is located recess 26, avoids user of service to knock on the handle 25 of evasive.

Both ends of the first screw rod 16 and the second screw rod 18 are sleeved with and fixed with a limiting block 27. The stop block 27 is arranged to prevent the two nut bases 21 from being disengaged from the first lead screw 16 and the second lead screw 18.

The working principle is as follows: when the bookcase body 1 needs to be moved, the motor 11 is started, the output shaft of the motor 11 rotates clockwise to drive the first bevel gear 14 fixedly connected with the motor to rotate, the first bevel gear 14 drives the second bevel gear 20 engaged with the first bevel gear to rotate, the second bevel gear 20 drives the intermediate rod 17 fixedly connected with the second bevel gear to rotate, and the intermediate rod 17 drives the first rotating rod 15, the first screw rod 16, the second screw rod 18 and the second rotating rod 19 to rotate, namely the whole rotating shaft 12 rotates. Because the lifting frame 13 plays a role in circumferential limiting of the two nut bases 21, and the thread directions of the first lead screw 16 and the second lead screw 18 are opposite, the two nut bases 21 respectively move oppositely along the first lead screw 16 and the second lead screw 18, so that the lifting frame 13 is driven to extend, and the two first sliding blocks 9 move oppositely along the guide rail 8. The lifting frame 13 drives the lifting plate 5 to move downwards, the second sliding block 23 moves downwards in the sliding groove 22, and the stability of the lifting plate 5 during up-and-down movement is improved. The lifting plate 5 drives the roller 10 to move downwards, the roller 10 penetrates out of the cavity 4 through the opening 6 and contacts with the ground, and the bookcase body 1 can be easily moved through the roller 10.

Similarly, when the bookcase body 1 moves to a designated position, the output shaft of the motor 11 rotates counterclockwise to drive the roller 10 to retract into the cavity 4, so that the bookcase body 1 is stably placed on the ground.

The utility model discloses in remove book case body 1's process labour saving and time saving, it is swift convenient.
