DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] The utility model provides two technical solutions:

[0024] Figures 1-5The first embodiment is shown: a mobile file cabinet with locking structure, comprising a file cabinet body 1, the left surface of the file cabinet body 1 is provided with a handle 4, the bottom of the file cabinet body 1 is provided with two steering assemblies 3 near the left side, and the two steering assemblies 3 are symmetrically distributed front and back, each steering assembly 3 is provided with a locking assembly 6, and the bottom of the handle 4 is provided with a lifting assembly 5 connected with the locking assembly 6; the steering assembly 3 comprises a steering wheel frame 31 rotatably installed on the bottom surface of the file cabinet body 1, a rotating shaft 32 penetratingly arranged on the steering wheel frame 31, and locking tooth rollers 34 mounted at both ends of the rotating shaft 32; the locking assembly 6 comprises an annular plate 62 surrounding the outer periphery of the steering wheel frame 31, a locking tooth disc 621 fixedly connected with the locking tooth rollers 34 on the bottom surface of the annular plate 62, and a spring 66 fixedly connected with the top surface of the annular plate 62, wherein the top end of the spring 66 is fixedly connected with the bottom surface of the file cabinet body 1, and the spring 66 can exert a downward pressure on the annular plate 62.

[0025] Specifically, the spring 66 exerts a downward pressure on the annular plate 62 to realize the locking function of the steering wheel frame 31 in the normal state, and the lifting assembly 5 at the bottom of the handle 4 is connected with the locking assembly 6, so that the state of the locking assembly 6 can be changed through lifting operation, thereby realizing the unlocking or locking of the steering wheel frame 31, so that the file cabinet can be unlocked when moving and automatically locked when parking, ensuring the flexible movement and stable parking of the file cabinet, solving the problem that the existing file cabinet is easily forgotten to be locked due to the negligence of the staff, and improving the safety and reliability of the file cabinet.

[0026] In the embodiment, a plurality of guide rods 61 slidingly penetrate the end portions of the annular plate 62, the top ends of the guide rods 61 are fixedly connected with the bottom surface of the file cabinet body 1, and the annular plate 62 can slide up and down tightly against the outer wall of the guide rods 61.

[0027] Specifically, the guide rods 61 can ensure that the annular plate 62 can stably move up and down along the predetermined straight line direction when subjected to the elastic force of the spring 66 or the pulling force of the lifting assembly 5, avoiding the annular plate 62 from deviating or rotating.

[0028] In the embodiment, the steering assembly 3 further comprises two hanging seats 64 arranged above the annular plate 62, the top surface of the hanging seat 64 is fixedly connected with the bottom surface of the file cabinet body 1, the opposite side surfaces of the two hanging seats 64 are rotatably connected with rotating rods 65, the outer surface of the rotating rod 65 is provided with a first straight slot 651 penetratingly arranged at the left side of the hanging seat 64, and the outer surface of the rotating rod 65 is provided with a second straight slot 652 penetratingly arranged at the left side of the first straight slot 651.

[0029] Specifically, the hanging seat 64 provides stable support and rotating connection point for the rotating rod 65, and the rotating rod 65 can rotate around the connection point with the hanging seat 64.

[0030] When the upward pulling force of the connecting shaft 54 acts on the first straight slot 651, the rotating rod 65 will rotate.

[0031] In this embodiment, the annular plate 62 top surface is symmetrically provided with a fixed seat 63, and the opposite side surfaces of the two fixed seats 63 are respectively provided with a fixed rod 631, and the fixed rod 631 is movably arranged in the first straight slot 651.

[0032] Specifically, when the rotating rod 65 rotates, the first straight slot 651 will be raised, thereby driving the fixed rod 631 upward.

[0033] In this embodiment, the file cabinet body 1 bottom surface is symmetrically provided with a moving wheel 2 near the right side, and the turning wheel frame 31 is internally provided with a roller 33 fixedly connected with a rotating shaft 32.

[0034] Specifically, the moving wheel 2 can help the file cabinet to move stably and linearly. At the same time, by rotating the turning wheel frame 31 and cooperating with the roller 33 to change the moving direction, the free movement of the file cabinet body 1 is realized.

[0035] Figures 1-5 The second embodiment is shown, and the main difference from the first embodiment is that the downward side surface of the handle 4 is symmetrically provided with a guide column 51, and a pull rod 52 is slidably connected between the two guide columns 51, and a connecting rod 53 is symmetrically movably sleeved on the outer surface of the pull rod 52, and a connecting shaft 54 is arranged on the outer surface of the connecting rod 53 near the bottom, and the connecting shaft 54 is movably arranged in the second straight slot 652.

[0036] Specifically, when the user operates the handle 4, the pull rod 52 is pulled to slide upward along the guide column 51, which drives the connecting rod 53 to move together. Since the connecting shaft 54 is in the second straight slot 652, the movement of the pull rod 52 is transmitted to the rotating rod 65 associated with it through the connecting rod 53 and the connecting shaft 54 and the cooperation of the second straight slot 652, which provides a control mechanism for the locking and unlocking operation of the file cabinet, ensures that the user can conveniently operate the moving state of the file cabinet, so that the file cabinet can be unlocked when it needs to move, and can be automatically locked after moving, thereby enhancing the convenience and safety of the file cabinet operation.

[0037] Meanwhile, the contents not described in detail in the specification all belong to the existing technology known to those skilled in the art.

[0038] Working principle: when the file cabinet body 1 needs to be moved, the user holds the handle 4 and pulls the pull rod 52 upwards, driving the connecting rod 53 to move upwards together, since the connecting shaft 54 is movably arranged in the second straight slot 652 of the rotating rod 65, the upward movement of the pull rod 52 will pull the rotating rod 65 to rotate relative to the hanging seat 64. The rotation of the rotating rod 65 will make the first straight slot 651 rise, thereby driving the fixed rod 631 to rise. The upward movement of the fixed rod 631 will pull the annular plate 62 to move upwards against the elastic force of the spring 66. After the annular plate 62 moves upwards, the locking tooth disc 621 on the bottom surface thereof is separated from the locking tooth roller 34, and the locking constraint on the steering wheel frame 31 is released, at this time, the file cabinet body 1 is freely moved through the moving wheels 2 and the rollers 33 at the bottom.

[0039] When the file cabinet body 1 is moved to the predetermined place and the staff leaves, the pull rod 52 will be naturally released, at this time, under the action of the pushing force of the spring 66, the annular plate 62 moves downwards, so that the locking tooth disc 621 is engaged with the locking tooth roller 34, realizing the locking of the steering wheel frame 31, solving the problem that the existing file cabinet is easily forgotten to be locked by the staff due to negligence, causing the file cabinet to move unexpectedly, improving the safety and reliability of the file cabinet.
