[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0026] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0027] See Figures 1-4 A safety box with a retractable pulley assembly includes a base 1, a pair of telescopic frames 2 slidably disposed on the inner wall of the base 1, a positioning component 3 disposed inside the telescopic frames 2, a rotating frame 4 rotatably connected to the inner wall of the telescopic frames 2 via a rotating shaft, a pulley 5 rotatably connected to one end of the rotating frame 4 via a rotating shaft, a box body 6 fixedly connected to the top of the base 1, and a box cover 7 rotatably disposed on one side of the box body 6.

[0028] The box body 6 is installed on the top of the base 1. A box cover 7 is rotatably connected to one side of the box body 6 for sealing the box body 6. When the box body 6 needs to be moved on the ground, the telescopic frame 2 is pulled out of the base 1, and the rotating frame 4 is rotated from a horizontal state to a vertical state, so that the pulley 5 at one end of the rotating frame 4 contacts the ground. The position of the rotating frame 4 is fixed by the positioning component 3, and the box body 6 can be moved by the pulley 5.

[0029] In the specific implementation process, such as Figure 3 As shown, the positioning component 3 includes a rod 31 that is slidably disposed on the inner wall of the telescopic frame 2. The top and one side of the rotating frame 4 are provided with insertion holes 32 that cooperate with the rod 31. One end of the rod 31 is fixedly connected to a pull plate 33. A pair of moving rods 34 are fixedly connected to one side of the pull plate 33. One end of the moving rod 34 is fixedly connected to a limit plate 35. A spring 36 is sleeved on the outside of the moving rod 34. A pull block 37 is fixedly connected to the other side of the pull plate 33.

[0030] When the insertion rod 31 is inserted into the insertion hole 32 at the top of the rotating frame 4, the rotating frame 4 is positioned in a horizontal state. When the insertion rod 31 is inserted into the insertion hole 32 on one side of the rotating frame 4, the rotating frame 4 is positioned in a vertical state. The pull plate 33 is pulled by the pull block 37, and the pull plate 33 drives the insertion rod 31 to move and separate from the insertion hole 32, which facilitates the release of the positioning of the rotating frame 4 and the rotation of the rotating frame 4. When the pull plate 33 moves, it simultaneously drives the moving rod 34 and the limiting plate 35 to move in the telescopic frame 2 and squeezes the spring 36, which facilitates the reset of the insertion rod 31 by the elastic force of the spring 36.

[0031] Guide bars 8 are fixedly connected to both sides of the telescopic frame 2. The outer side of the guide bars 8 is slidably connected to the inner wall of the base 1. When the telescopic frame 2 moves inside the base 1, the guide bars 8 on both sides guide and limit the telescopic frame 2.

[0032] A limit block 9 is fixedly connected to one side of the telescopic frame 2. The limit block 9 limits the telescopic frame 2 and prevents the telescopic frame 2 from sliding off the base 1.

[0033] A pair of support blocks 10 are fixedly connected to one side of the bottom of the base 1, which can support and fix one side of the bottom of the box 6.

[0034] A safety lock 11 is provided on one side of the box body 6, and a lifting handle 12 is slidably provided on the top of the box body 6. The safety lock 11 securely locks the box body 6 and the lid 7, and the lifting handle 12 facilitates pulling and lifting the box body 6.

[0035] When in use, pull the telescopic frame 2 out of the base 1, and pull the pull plate 33 by the pull block 37. The pull plate 33 drives the insertion rod 31 to move and separate from the insertion hole 32, which makes it easy to release the positioning of the rotating frame 4. Rotate the rotating frame 4 from the horizontal state to the vertical state, so that the pulley 5 at one end of the rotating frame 4 contacts the ground, and the box 6 can be moved by the pulley 5.

[0036] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape, and proportions of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application). For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered.
