[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1 to 4 The illustrated multifunctional steel and wood bookshelf includes a fixing frame 1. In this embodiment, the fixing frame 1 is a vertical U-shaped frame. The rear side of the fixing frame 1 is closed.

[0025] A fixed book frame 2 is fixedly installed inside the fixed frame 1, and a movable book frame 3 is installed on the top of the fixed book frame 2.

[0026] A guide groove 13 is provided on both the left and right sides of the fixed frame 1. The openings of the two guide grooves 13 are horizontally opposite each other and both penetrate through the frame. The movable book frame 3 is located between the two guide grooves 13.

[0027] Each guide groove 13 consists of interconnected horizontal and vertical grooves, which together form an inverted L-shaped groove. The two guide grooves 13 are located in front of the fixed book frame 2.

[0028] Each guide groove 13 has a slider 7 that is slidably installed in a limited position, and the movable book frame 3 is rotatably connected to the two sliders 7.

[0029] Two horizontal pivots 8 are fixedly mounted on the movable book frame 3. The two pivots 8 are coaxially opposite each other and correspond one-to-one with the two sliders 7. Each pivot 8 passes through the corresponding slider 7 in a horizontal direction and is rotatably connected to the corresponding slider 7. Each slider 7 is equipped with a drive component that drives the corresponding pivot 8 to rotate and has a self-locking function.

[0030] Specifically, the drive assembly includes a worm gear 9 and a worm 12. A mounting plate 10 is fixedly mounted on the end of the slider 7 away from the movable book frame 3, and the worm 12 is rotatably mounted on the mounting plate 10 in a horizontal direction. The worm gear 9 is coaxially and fixedly connected to the rotating shaft 8, and the worm gear 9 meshes with the worm 12.

[0031] A linkage assembly for driving the worm gear 12 to rotate is installed between the mounting plate 10 and the fixed book frame 2. The worm gear 12 is connected to the moving book frame 3 through the linkage assembly.

[0032] Specifically, the linkage assembly includes a gear 11 and a rack 15. The gear 11 is coaxially and fixedly connected to the worm gear 12. A support frame 14 is fixedly installed on the outer side wall of the fixed frame 1, and the rack 15 is fixed vertically on the support frame 14. The gear 11 and the rack 15 are in contact meshing engagement.

[0033] The fixed frame 1 is equipped with a power source that drives the slider 7 to slide along the guide groove 13. One slider 7 corresponds to one power source, and the two power sources work synchronously.

[0034] Specifically, the power source includes an electric push rod 6. A horizontal support shaft 5 is fixedly installed on the outer side wall of the fixed frame 1, and the support shaft 5 is parallel to the rotating shaft 8. A rotating seat 4 is rotatably mounted on the support shaft 5, and the electric push rod 6 is fixed on the rotating seat 4. The telescopic shaft of the electric push rod 6 is hinged to the slider 7.

[0035] Working principle: When a book needs to be retrieved from the movable book frame 3, the two electric push rods 6 are activated, and their telescopic shafts extend synchronously. At this time, the telescopic shafts of the two electric push rods 6 push the corresponding sliders 7 to slide along the guide grooves 13. The two sliders 7 drive the movable book frame 3 to move synchronously. Simultaneously, the two electric push rods 6 rotate.

[0036] The process of the two sliders 7 sliding along the guide groove 13 is as follows: the two sliders 7 slide forward synchronously along the horizontal groove of the guide groove 13. At this time, the two sliders 7 drive the movable book frame 3 to move out of the fixed frame 1. When the two sliders 7 slide to the front end of the horizontal groove, the rear end of the movable book frame 3 is located in front of the front end of the fixed book frame 2 with a gap between them. Then, the two sliders 7 slide downward synchronously along the vertical groove of the guide groove 13. At this time, the two sliders 7 drive the movable book frame 3 to move downward. In this embodiment, both sliders 7 are square blocks.

[0037] When the two sliders 7 move downwards, they drive the corresponding mounting plates 10 to move downwards simultaneously. The two mounting plates 10 drive the corresponding worm gears 12 to move downwards simultaneously, and the two worm gears 12 drive the corresponding gears 11 to move downwards simultaneously.

[0038] As the two gears 11 move downwards, they gradually contact and mesh with the corresponding racks 15. After the two gears 11 mesh with the corresponding racks 15, the two gears 11 rotate synchronously, driving the corresponding worm gears 12 to rotate synchronously. At this time, the two worm gears 12 drive the corresponding worm wheels 9 to rotate. The two worm wheels 9 drive the corresponding rotating shafts 8 to rotate, and the two rotating shafts 8 drive the movable book frame 3 to rotate backwards.

[0039] When the movable book frame 3 reaches the predetermined height, the top of the movable book frame 3 tilts backward at a certain angle to facilitate viewing the book title. At this time, the two sliders 7 slide down to the bottom of the corresponding vertical slots.

[0040] Then, simply take out the books you need.

[0041] After the books are taken, the telescopic shafts of the two electric actuators 6 retract, causing the corresponding sliders 7 to slide back. During this process, the two gears 11, two worm gears 12, two worm wheels 9, and two rotating shafts 8 reverse, causing the movable book frame 3 to rotate back to a vertical position. Then, the two gears 11 disengage from the corresponding racks 15, and the movable book frame 3 returns to its original position along with the two sliders 7.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
