Detailed implementation manner

[0023] The present invention will be further described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] As Figure 1-4 shown, a compact shelf with confidentiality and anti-theft functions includes a plurality of frame bodies 1, guide rails 2 and turntables 3. The plurality of frame bodies 1 are installed on the guide rails 2. A lock plug block 4 and a lock mechanism 5 are respectively provided on the upper sides of adjacent two frame bodies 1 and on the front side where the turntable 3 is installed. That is, a lock plug block 4 is installed on one frame body, and a lock mechanism 5 is installed on the other frame body. The two cooperate to lock the adjacent frame bodies together. Specifically, a plurality of lock holes 19 are provided on the lock plug block 4, and the head of the lock plug block 4 is provided with an inclined guiding slope. Refer to Figure 4As shown in the figure, the guiding inclined plane makes the head of the plug lock block 4 form a right triangle structure. The lock mechanism 5 includes a lock catch 6, an unlocking screw rod 7, a connecting rod 8, a first mounting block 9, a second mounting block 10 and an adjusting lock rod 11. The lock catch 6 is in a U-shaped structure. A main plug rod 15 and an alarm mechanism are installed on the lock catch 6. The main plug rod 15 is installed on one side inside the U-shaped structure. The closed side of the lock catch 6 is fixedly connected to the adjusting lock rod 11 through the connecting rod 8. The connecting rod 8 and the adjusting lock rod 11 form an L-shaped structure. The first mounting block 9 and the second mounting block 10 are two parallel plates fixedly installed on the frame body 1. The adjusting lock rod 11 passes through the mounting holes on the first mounting block 9 and the second mounting block 10, and the first mounting block 9 is arranged close to the connecting rod 8. A plurality of uniformly distributed adjusting grooves 13 are provided on the adjusting lock rod 11. A positioning lock block 14 is inserted into one of the adjusting grooves 13, and the positioning lock block 14 is located between the first mounting block 9 and the second mounting block 10. A positioning shoulder is also provided on the adjusting lock rod 11 between the first mounting block 9 and the second mounting block 10. A pressing spring 12 is sleeved on the adjusting lock rod 11 between the positioning shoulder and the mounting block 10. At the same time, the adjusting lock rod 11 should have a guiding function, only allowing the lock catch 6 to move along the length direction of the adjusting rod 11 and not allowing relative axial rotation with respect to the adjusting rod 11. For example, the end of the guiding rod 11 can be set to a rectangular structure, and the corresponding mounting hole on the second mounting block 10 is also set to a rectangular shape; the thickness of the lock plug block 4 is greater than the distance between the two farthest adjusting grooves 13; the unlocking screw rod 7 is installed on the frame body 1 through a threaded structure. One end of the unlocking screw rod 7 extends into the frame body 1 and outside the lock catch 6. A scale line 27 is provided on the side of the unlocking screw rod 7, and the spacing of the scale line 27 is set to be equal to the spacing of the adjusting grooves 13. When the positioning lock block 14 is inserted into the adjusting groove 13 closest to or farthest from the connecting rod 8, when the lock plug block 4 is engaged with the lock mechanism 5, the end of the main plug rod 15 is within the range of the guiding inclined plane of the lock plug block 4, that is, the end of the main plug rod 15 first contacts the guiding inclined plane of the lock plug block 4. Under the extrusion of the guiding inclined plane, the lock catch 6 drives the positioning shoulder of the adjusting lock rod 11 to compress the pressing spring 12 until the main plug rod 15 is inserted into the lock hole 19 for locking.

[0025] Preferably, a secondary plug rod 18 is further provided on the side of the U-shaped lock catch 6 opposite to the main plug rod 15. The installation end of the secondary plug rod 18 is installed using the same structure as the main plug rod 15. The circuit composed of the moving conductive contact piece 22 and the static conductive contact piece 23 at the installation end of the secondary plug rod 18 is connected in parallel with the circuit at the installation end of the main plug rod 15. The distance between the secondary plug rod 18 and the main plug rod 15 is greater than 3-5 mm of the thickness of the lock plug block 4.

[0026] As Figure 6 and Figure 7As shown, the alarm mechanism includes a storage battery 16 and a buzzer 17 installed on the back of the lock catch 6. The storage battery 16 is electrically connected to the buzzer 17 through a wire. On one side of the lock catch 6 where the main insertion rod 15 is installed, there is a sliding groove 21. On the installation section of the main insertion rod 15, there is a sliding block 20 that cooperates with the sliding groove 21. On the side of the sliding block 20 facing the lock insertion block, there is a moving conductive contact piece 22. On the side of the sliding groove 21, there are two separated static conductive contact pieces 23. The two static conductive contact pieces 23 are connected in series in the circuit of the storage battery 16 and the buzzer 17. On the side of the sliding block 20 where the moving conductive contact piece 22 is provided, there is a guiding rod 24. On the side of the sliding groove 21 where the static conductive contact piece 23 is provided, there is a guiding groove. A return spring 25 is installed in the guiding groove. The return spring 25 is sleeved outside the guiding rod 24 and pushes the sliding block 20 to closely adhere to the other side of the sliding groove 21. At this time, the moving conductive contact piece 22 is separated from the static conductive contact piece 23. When the unlocking screw rod 7 is not adjusted to the unlocking position, the main insertion rod 15 or the auxiliary insertion rod 18 is partially located in the lock hole 19. When the turntable 3 is forcibly rotated to separate the two frame bodies 1, the lock insertion block 4 will apply a pulling force to the main insertion rod 15 or the auxiliary insertion rod 18. When the pulling force is greater than a certain value, the moving conductive contact piece 22 at the installation end of the main insertion rod 15 or the auxiliary insertion rod 18 will contact the static conductive contact piece 23, conducting the circuit of the buzzer 17 and the storage battery 16, and the buzzer 17 will sound an alarm.

[0027] As Figure 5 shown, the positioning lock block 14 is composed of two semi-circular structures. Inside the two semi-circular structures, there are magnets installed, and the outside can be wrapped with a metal material to increase the strength of the positioning lock block 14. The positioning lock block 14 formed in a ring shape through magnetic attraction force. On the inner side of one of the semi-circular structures, there is a clamping block 29 that cooperates with the adjusting groove 13. Similarly, the adjusting groove 13 can be an annular groove. After the two positioning lock blocks 14 are adsorbed by the magnets, their inner diameter is smaller than the diameter of the adjusting lock rod 11 and is just clamped in the adjusting groove 13.

[0028] As Figure 8 shown, on one side of the unlocking screw rod 7, there is a scale groove 26, and scale lines 27 are evenly arranged in the scale groove 26. Further, at one end of the unlocking screw rod 7 located outside the frame body 1, there is a knob.

[0029] Preferably, there are three lock holes 19 on the lock insertion block 4, and the quantity and positions of the main insertion rod 15 and the insertion rod 18 correspond to the quantity and positions of the lock holes 19. Preferably, the quantity of the adjusting grooves 13 is six. At this time, there are 6×6×6 = 216 kinds of unlocking positions for the corresponding unlocking screw rod 7. Similarly, to increase the unlocking difficulty of the lock catch mechanism 5, the quantity of the lock holes 19 can be increased. When there are 4 lock holes 19, the unlocking positions are 6×6×6×6 = 1296 kinds. Specifically, it can be designed according to the usage requirements.

[0030] Preferably, the plug lock block 4 and the lock mechanism 5 can be designed as independent structures and can be installed on the frame body 1 through a bolt structure, which is convenient for replacement after damage. Only the corresponding installation positions need to be reserved during the design of the frame body 1.

[0031] Working principle: Set the unlocking position. At this time, the frame bodies 1 are separated. Adjust the unlocking screw rod 7 so that all its scale lines 27 are located outside the frame body 1 (to ensure that the unlocking screw rod 7 does not press against the lock catch 6 during adjustment). Adjust the positioning lock block 14 to be inserted into the preset adjustment groove 13 and record which adjustment groove 13 it is inserted into. Insert the positioning blocks 14 into the adjustment grooves 13 on the three adjustment lock rods 11 in sequence. During adjustment, you can use your hand to press against the lock catch 6 to compress the compression spring 12, and then insert the positioning lock block 14 to complete the presetting of the lock mechanism 5. When unlocking, rotate the unlocking screw rod 7 so that the corresponding scale line 27 is aligned with the outer side of the frame body 1. At this time, the unlocking screw rod 7 just pushes the main insertion rod 15 of the lock catch 6 away from the lock hole, and the two adjacent frame bodies 1 can be separated. If the position of the unlocking screw rod 7 is incorrect, the main insertion rod 15 or the auxiliary insertion rod 18 will be partially located in the lock hole 19. If you forcibly rotate the turntable 3 to separate the two frame bodies 1 to unlock, the lock plug block 4 will exert a pulling force on the main insertion rod 15 or the auxiliary insertion rod 18. When the pulling force is greater than a certain value, the moving conductive contact piece 22 at the installation end of the main insertion rod 15 or the auxiliary insertion rod 18 will contact the static conductive contact piece 23, conducting the circuit of the buzzer 17 and the storage battery 16, and the buzzer 17 will sound an alarm to achieve the anti-theft effect.

[0032] This specific embodiment is only an explanation of the present invention, and it is not a limitation of the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
