[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-6 This utility model provides a technical solution: a school-specific locker based on RFID, including a cabinet frame 1 and multiple cabinet bodies 2. The multiple cabinet bodies 2 are installed inside the cabinet frame 1. Multiple placement plates 9 are rotatably installed inside the cabinet bodies 2. Multiple adjustment components and drive components are provided on the inner wall of the cabinet bodies 2. The adjustment components are connected to the placement plates 9 through transmission. Each of the multiple adjustment components includes two rotating columns 21 rotatably installed on both sides of the inner wall of the cabinet body 2. The opposite ends of the two rotating columns 21 are fixedly connected to the opposite sides of the corresponding placement plates 9. The inner wall of the cabinet body 2 has an installation groove 11. A connecting block 20 is provided in the installation groove 11. One end of the connecting block 20 is fixedly installed on the side wall of one of the rotating columns 21. A connecting rod 19 is fixedly installed on the side wall of the connecting block 20. A ball bearing 18 is movably installed on the other end of the connecting rod 19. A rotating block 17 is rotatably installed in the installation groove 11. A limit groove 16 is provided on the top of the rotating block 17. The limit groove 16 is divided into a horizontal section one, a vertical section, a horizontal section two, and a ramp section. The ball bearing 18 is movably installed in the limit groove 16.

[0021] The working principle of the above technical scheme is as follows: when the students need to place large articles, the driving assembly is driven to drive the rotating block 17 to rotate, so that the ball 18 moves in the limiting groove 16, and the ball 18 moves to the vertical section and the horizontal section II, under the self-gravity of the placing plate 9, the rotating column 21 is driven to rotate clockwise, the connecting block 20 is lowered, and during this period, the rotating block 17 is still rotating counterclockwise, so that the placing plate 9 slowly rotates from the horizontal state to the vertical state, at this time, the space in the cabinet 2 is the largest, and larger articles can be placed; when the students need to place different types of articles, continue to drive the driving assembly to drive the rotating block 17 to rotate, so that the ball 18 moves from the horizontal section II, first moves to the inclined section, during the movement of the ball 18 in the inclined section, the rotating column 21 is driven to rotate counterclockwise, the connecting block 20 is reset to move up, and during this period, the rotating block 17 is still rotating counterclockwise, so that the placing plate 9 slowly recovers from the vertical state to the horizontal state, when the ball 18 moves to the horizontal section I, the placing plate 9 is always in the horizontal state, so as to divide the cabinet 2 into layers, and different layers can place different types of articles.

[0022] In another embodiment, as shown in Figures 3-6 The driving assembly includes a rectangular groove 10 opened in the side wall of the cabinet 2, a rotating shaft 14 and a rotating column 15 are rotatably installed in the rectangular groove 10, a gear one 12 is fixedly installed on the outer wall of the rotating shaft 14, a gear two 13 is fixedly installed on the outer wall of the rotating column 15, the gear two 13 is engaged with the gear one 12, and the bottom end of the rotating column 15 penetrates the inner wall of the cabinet 2 and is fixedly installed with the inside of a plurality of rotating blocks 17.

[0023] By rotating the gear one 12 with fingers, the gear two 13 is engaged with the gear one 12 to drive the rotating column 15 to rotate, drive the adjusting assembly, and change the state of the placing plate 9, when the students need to place different types of articles, adjust the placing plate 9 to the horizontal state; when the students need to place large articles, adjust the placing plate 9 to the vertical state.

[0024] In another embodiment, as shown in Figures 1-6 The side wall of the cabinet 2 is symmetrically provided with two limiting frames 3, and the cabinet door 4 is arranged between the two limiting frames 3, the cabinet door 4 is installed on the side wall of the cabinet 2, the cabinet door 4 is installed with a handle 5 away from the side wall of the cabinet 2, the side wall of the handle 5 is provided with an inductor 6, the inner wall of the cabinet door 4 is provided with an electromagnet 7, and the inner wall of the cabinet 2 is provided with a magnet 8.

[0025] When the RFID card is close to the inductor 6, the inductor 6 will send a radio frequency signal of a specific frequency, the inductor 6 will send the received ID to the background system, the system compares the legal ID in the database, then the electromagnet 7 is powered off, so that the electromagnet 7 does not have magnetism, and then pulls the handle 5, the cabinet 2 can be opened; when the RFID card is away from the inductor 6, the electromagnet 7 is powered on again, the electromagnet 7 after being powered on restores the magnetism, and is attracted to the magnet 8, so that the cabinet 2 returns to the locked state.

[0026] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
