DETAILED DESCRIPTION

[0020] In order to enable the above-mentioned purpose, features and advantages of the utility model to be more clearly understood, the utility model is further described below in conjunction with the drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, however, the present application can also be implemented in other ways different from those described herein, therefore, the present application is not limited to the specific embodiments disclosed in the following description.

[0022] Embodiment one: as shown in Figure 1 , Figure 2 and Figure 4 , the utility model provides a child safety lock iron box, including box body 1 and top cover 3, the top of box body 1 is fixedly connected with two second rotating frames 31, and the inner side of second rotating frame 31 is rotatably connected with rotating block 32, and rotating block 32 is fixedly connected with top cover 3, and one side of box body 1 is provided with locking mechanism 2;

[0023] Locking mechanism 2 includes rotating sleeve 21, and the inner cavity of rotating sleeve 21 is threadedly connected with two threaded rods 22, and the opposite end of the two threaded rods 22 is fixedly connected with linkage block 23, one of linkage block 23 is rotatably connected with fixed frame 24, and the other linkage block 23 is rotatably connected with movable plate 25, and one end of movable plate 25 is fixedly connected with limiting plate 26, and the bottom of limiting plate 26 is rotatably connected with a plurality of first rotating frames 27, and the bottom of first rotating frame 27 is fixedly connected with the top of box body 1.

[0024] The specific settings and effects of the embodiment will be described below, the whole operation process is started by rotating the outer surface handle of rotating sleeve 21. The rotation of rotating sleeve 21 causes the relative movement of the two threaded rods 22, one of the threaded rods 22 drives movable plate 25 to start moving through the connection with movable plate 25. The movement of movable plate 25 plays a key role in this process, ensuring the dynamic adjustment and position control of the system.

[0025] Meanwhile, another threaded rod 22 cooperates with the linkage block 23 to provide the necessary support force. The relative rotation between the linkage block 23 and the fixed frame 24 further promotes the rotation of the limiting plate 26, ensuring that the limiting plate 26 can work stably during rotation. When the limiting plate 26 rotates to a certain angle, it will jam one side of the top of the box body 1, thereby preventing the top cover 3 from being moved randomly in an unintended manner. The core goal of this design is to avoid the loosening or incorrect opening of the top cover 3, thereby ensuring the safety of the contents of the box body 1 and avoiding unnecessary damage caused by external factors.

[0026] To ensure the reliability and safety of this process, the rotating sleeve 21 needs to be rotated multiple times to complete the locking. Through such a multi-step rotation mechanism, it can effectively prevent children from opening the box body 1 randomly, ensuring the integrity and safety of the contents of the box body 1. This design not only optimizes the smoothness of operation, but also enhances the protection measures to avoid damage to the contents due to improper operation or accidents.

[0027] In addition, this multi-rotation design can also enhance the durability and long-term stability of the system, ensuring that the top cover 3 can always remain fixed during long-term use. The ingenious construction and detailed design of the system take into account both ease of operation and high safety, making the device adaptable to different use scenarios and providing lasting protection.

[0028] Embodiment Two: As shown in Figure 1 and Figure 2 , the first fixed block 4 is fixedly connected to one side of the top of the box body 1, and the second fixed block 5 is fixedly connected to the other side of the top of the box body 1. The insertion rod 41 is slidingly connected to the inner side of the first fixed block 4, and the limiting block 42 is fixedly connected to the outer surface of the insertion rod 41. The limiting block 42 is slidingly connected to the inner cavity of the first fixed block 4, and the spring 43 is sleeved on the outer surface of the insertion rod 41. The screw 51 is threadedly connected to the middle of the second fixed block 5, and the insertion slots 33 are formed on both sides of the top cover 3. One of the insertion slots 33 is inserted with the screw 51, and the other insertion slot 33 is inserted with the insertion rod 41. The side wall of the fixed frame 24 is fixedly connected to the side wall of the box body 1.

[0029] The effect achieved by the entire embodiment is that during the locking of the top cover 3, the top cover 3 can be initially fixed by the screw 51 to ensure that it does not loosen during operation. This process provides a basis for subsequent precise positioning and multiple locking. By utilizing the elasticity of the spring 43, the limiting block 42 can be pushed to slide within the first fixed block 4, thereby driving the insertion rod 41 to cooperate with the insertion slot 33 to achieve precise insertion positioning of the top cover 3. At this time, the elasticity of the spring 43 not only serves to push the limiting block 42, but also ensures that the insertion rod 41 can be smoothly inserted into the insertion slot 33 and tightly combined with the insertion slot 33, further enhancing the locking effect.

[0030] The design of the multiple locking structure provides more stable security. Through the multi-point locking mechanism, not only the stability of the top cover 3 is improved, but also the loosening of the top cover 3 caused by vibration or external force during use is effectively prevented, thereby significantly improving the safety of the overall system.

[0031] During the movement of the insertion rod 41, the width of one end is designed to be greater than the width of the inner cavity of the first fixed block 4, which cleverly plays a limiting role. The width of the insertion rod 41 limits its movement to a specific position, thereby avoiding the disengagement of the insertion rod 41 from the first fixed block 4. Through cooperation with the limiting block 42, the insertion rod 41 is precisely positioned during insertion and locking, and the disengagement of the insertion rod 41 from the first fixed block 4 is prevented.

[0032] The use method and working principle of the device are as follows: rotating operation is performed by rotating the handle on the outer surface of the rotating sleeve 21. During rotation, the two threaded rods 22 begin to move relative to each other. One of the threaded rods 22 drives the movable plate 25 to move, and in this process, the other threaded rod 22 cooperates with the linkage block 23 to provide support, while the linkage block 23 rotates relative to the fixed frame 24, thereby controlling the rotation of the limiting plate 26. After the limiting plate 26 rotates, it is clamped on one side of the top of the box body 1, thereby preventing the top cover 3 from being moved at will, and completing the locking operation. During this process, the rotating sleeve 21 needs to be rotated multiple times, which can effectively prevent children from opening the box body 1 and prevent the contents inside the box body 1 from being damaged.

[0033] When locking the top cover 3, the bolt 51 is first used for preliminary fixation. Then, the elastic action of the spring 43 pushes the limiting block 42 to slide in the first fixed block 4, driving the insertion rod 41 to insert into one of the insertion grooves 33 of the top cover 3, thereby achieving insertion positioning of the top cover 3. This multiple locking method can further improve the locking effect and enhance the safety. It should be noted that the width of the movable end of the insertion rod 41 is greater than the width of the inner cavity of the first fixed block 4, which can play a limiting role, and in cooperation with the limiting block 42, the insertion rod 41 can be prevented from disengaging from the first fixed block 4.

[0034] The above is only a preferred embodiment of the present application, and is not intended to limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technology content to apply to other fields with equivalent changes. However, any simple modification, equivalent change and modification made on the basis of the technical essence of the present application to the above embodiments still falls within the protection scope of the present application.
