Description

Technical Field

[0001] The present invention relates to the technical field of book storage equipment, and in particular to a book storage shelf with adjustable storage space. Background Art

[0002] Bookshelves are tools used by people to store books. Due to different shapes and structures, bookshelves are called bookcases, bookcases, book dividers, etc. Bookshelves are common tools in our lives. Bookshelves in libraries can be divided into metal bookshelves and wooden bookshelves according to their materials. Metal bookshelves can be further divided into single-column, multi-column, stacked bookshelves, dense bookcases, and sliding bookshelves.

[0003] The overall structure of the existing book storage bookshelf is fixed. When the bookshelf is full and can no longer accommodate books, it is often necessary to prepare another bookshelf, which increases the demand for floor space for placing the new bookshelf and is not conducive to the utilization of limited space. Summary of the invention

At the same time, the bookshelf with adjustable space reduces the floor space and improves the space utilization rate.

[0007] In a preferred embodiment, the capacity adjustment module includes a screw rod 1, wherein a fine hole is formed on one of the support plates, and the inner wall of the fine hole is movably connected to the outside of the screw rod 1. The screw rod 1 is located below the lowest support plate 1 among the three support plates 1.

[0023] Specifically, when it is necessary to expand the capacity of the bookshelf, the capacity adjustment module 6 installed on the support plate 1 is operated to push the two support plates 1 away from each other. With the assistance of the universal wheel 5, the distance between the two support plates 1 is gradually expanded, so that the support plate 1 2 and the support plate 2 3 installed on the two support plates 1 slide against each other, thereby increasing the area on which books can be placed on the support plates 1 2 and 2 3.

[0027] Reference Figure 7In a preferred embodiment, the deformation compensation module 7 includes a plurality of equally spaced rectangular grooves 701, the plurality of rectangular grooves 701 are respectively provided on the same side of the two support plates 1, a circular groove 702 is provided below the rectangular grooves 701, the circular grooves 702 are provided on the support plates 1, and a circular groove 709 is provided on the bottom inner wall of the rectangular grooves 701, the circular grooves 709 are connected to the circular grooves 702 located on the same plane, and the circular grooves 709 are rotatably connected to the second screw rod 703 through bearings; the bottom of the second screw rod 703 is connected to a knob 708 through a bolt, and the outside of the knob 708 is connected to the same The inner wall of the circular groove 702 on the side is slidably connected, and the outside of the screw rod 2 703 is provided with a movable part 704, and the outside of the movable part 704 is slidably connected to the inner wall of the rectangular groove 701 on the same side; the outsides of the supporting plate 1 2, the supporting plate 2 3 and the movable part 704 are connected with the connecting shaft 705 by bolts, and the outside of the connecting shaft 705 is rotatably connected with the screw rod 706 through the bearing, and the screw rod 706 on the connecting shaft 705 on the movable part 704 on the same side and the screw rod 706 on the connecting shaft 705 on the supporting plate 1 2 or the supporting plate 2 3 on the same side are provided with the same sleeve 707.

[0028] Specifically, after the capacity of the bookshelf is adjusted, according to the degree of increase or decrease in the capacity, the knob 708 is turned, and the knob 708 drives the screw rod 2 703 to rotate, so that the movable part 704 on the screw rod 2 703 moves on the rectangular groove 701. During the movement of the movable part 704, the screw rod 706 connected to the connecting shaft 705 on the supporting plate 1 2, the supporting plate 2 3 and the connecting shaft 705 rotates with the movement of the movable part 704 under the restraint of the sleeve 707.

After the movable part 704 reaches the position, the sleeve 707 is rotated to tighten the two screw rods 706 on the sleeve 707.

[0029] In specific application scenarios, the deformation compensation module 7 is mainly suitable for the deformation compensation link in the deformation compensation process, that is, the deformation compensation module 7 uses the screw rod 2 703 and the movable part 704 to quickly and conveniently complete the angle and length adjustment of the screw rod 706 and the sleeve 707, and uses the triangular force system formed by the screw rod 2 703 and the screw rod 706 to effectively reversely tension the support plate 1 2 and the support plate 2 3 that bear the weight of the books, and compensate the force of the support plate 1 2 and the support plate 2 3, thereby ensuring the stability of the connection between the support plate 1 2 and the support plate 2 3 on the support plate 1, avoiding the deformation of the support plate 1 2 and the support plate 2 3, and improving the service life of the bookshelf.

[0030] Working principle: When the bookshelf space needs to be adjusted, the locking rod 619 is pulled out to overcome the elastic force of the second spring 621, thereby releasing the locking rod 619 from the fitting opening 618, rotating the limit rod 615 from the iron block 617, so that the bayonet 616 releases the locking of the T-shaped piece 614, and the pedal 609 is lightly stepped on to make the pedal 609 rotate downward to overcome the torsion of the torsion spring 610, so that the pedal 609 presses downward to push the contact plate 606 connected to the locking ring 604, and the contact plate 606 drives the locking ring 604 to slide downward on the guide buckle 605 The outer gear ring 603 is unlocked by the rack 612 on the locking ring 604, and the handle 624 is grasped and rotated, so that the rotating shaft 622 connected to the handle 624 drives the transmission roller 623 to rotate, so that the belt 611 on the transmission roller 623 drives the transmission roller 623 on the screw rod 1 601 to rotate, and the rotating screw rod 1 601 pushes the fixed seat 602 connected to the supporting plate 1 2, so that the screw rod 1 601 can gradually push the support plate 1 connected to the supporting plate 1 2 and the support plate 1 connected to the supporting plate 2 3 away from each other. 5, the support plates 1 2 and the support plates 2 3 on the two support plates 1 slide against each other, so that the placement area formed by the support plates 1 2 and the support plates 2 3 is increased. After the adjustment is completed, the above steps are reversed to reset the locking ring 604 and re-lock the screw rod 1 601 connected to the outer gear ring 603, so that the distance between the two support plates 1 does not change. The adjustment is completed. After the bookshelf capacity is adjusted, according to the degree of increase or decrease in the capacity, the knob 708 is turned, and the knob 708 drives the screw rod 2 703 to rotate, so that the screw rod 2 703 is adjusted. The movable part 704 moves on the rectangular groove 701. During the movement of the movable part 704, the screw 706 connected to the connecting shaft 705 on the supporting plate 1 2, the supporting plate 2 3 and the connecting shaft 705 rotates with the movement of the movable part 704 under the restraint of the sleeve 707. The sleeve 707 is rotated to tighten or release the screw 706, so that the movable part 704 can move to an appropriate position. After the movable part 704 reaches the position, the sleeve 707 is rotated to tighten the two screws 706 on the sleeve 707.
