[0002] Compact shelving, also known as compact cabinets, is a type of intensive filing equipment. It is not only used for the storage of archival materials, but is also suitable for the storage of books, archival materials, archival financial vouchers, goods and other items in the data rooms and sample rooms of courts, procuratorates, banks, large shopping malls, schools, corporate units.
[0003] The utility model patent with patent authorization announcement number CN 220124253 U discloses a compact shelving bottom anti-collapse structure, including a compact shelving, the bottom of which is fixedly connected to a bottom pulley assembly, the bottom pulley assembly includes a base bracket, the interior of the base bracket is fixedly connected to a partition, the interior of the base bracket is fixedly connected to a first rotating rod, the outer wall of the first rotating rod is rotatably connected to a pulley, and one side of the base bracket is fixedly connected to a first slide rail.
[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that although the top pulley assembly can be used to improve the stability of the compact shelving during movement, the actual installation of the top pulley assembly requires relying on the indoor ceiling. Since there is still a distance between the top of the compact shelving and the indoor ceiling, the top pulley assembly is very inconvenient in actual installation, which will not only increase the installation cost of the compact shelving, but also consume more manpower during the installation process.
[0005] Therefore, it is necessary to invent a compact rack base to solve the above problems. Utility Model Content
[0006] The utility model aims to provide a base frame of a compact shelving system, which is provided with a limited movement mechanism so that when the connecting frame is pushed, the moving adjustment mechanism can be moved by means of four moving wheels, and due to the limiting effect of the L-shaped limiting plate on the moving wheels, the connecting frame, the moving adjustment mechanism and the compact shelving main body on the top of the connecting frame cannot be tilted. In addition, when the limited movement mechanism is disassembled, the bidirectional screw is rotated to make the bidirectional screw drive the two moving plates closer to each other. At this time, the moving wheel rolls on the surface of the bottom plate through the moving roller, and then the moving wheel is gradually moved out from the inner side of the L-shaped limiting plate, so as to solve the problem proposed in the above background technology that although the top pulley assembly can be used to improve the stability of the compact shelving during movement, the actual installation of the top pulley assembly needs to rely on the indoor ceiling. Since there is still a distance between the top of the compact shelving and the indoor ceiling, the top pulley assembly is very inconvenient during actual installation, which will not only increase the installation cost of the compact shelving, but also consume more manpower during the installation process.
[0007] According to one aspect of the present disclosure, the following technical solution is provided: a compact shelf base frame, comprising:
[0008] A connecting frame, wherein the connecting frame is used to install the mobile adjustment mechanism;

[0011] The rotating shaft passes through the movable plate and is rotatably connected to the movable plate through a bearing. The movable wheel is fixedly sleeved on the outer end of the rotating shaft. A plurality of movable rollers are provided. The plurality of movable wheels are evenly nested on the movable wheel through bearings. The bottom plate is attached to the bottom of the movable wheel, and the L-shaped limiting plate is fixedly arranged on the top of the bottom plate.
[0012] According to the compact shelving base frame of at least one embodiment of the present disclosure, the movement and adjustment mechanism includes a guide plate, a moving plate and a bidirectional screw.
[0013] According to at least one embodiment of the compact shelving base frame of the present disclosure, two guide plates are provided, and the two guide plates are respectively fixedly disposed on both sides of the interior of the connecting frame.
[0014] According to at least one embodiment of the compact shelving base frame of the present disclosure, two movable plates are provided, and both of the two movable plates are slidably sleeved on the outsides of the two guide plates and located at the two ends of the inner side of the connecting frame.

[0016] Technical effects and advantages of the utility model:
[0017] The utility model sets a limited movement mechanism, so that when the connecting frame is pushed, the moving adjustment mechanism moves through four moving wheels, and due to the limiting effect of the L-shaped limiting plate on the moving wheels, the connecting frame and the moving adjustment mechanism and the compact shelving body on the top of the connecting frame cannot be tipped over. In addition, when the limited movement mechanism is disassembled, the bidirectional screw is rotated to make the bidirectional screw drive the two moving plates approach each other. At this time, the moving wheel rolls on the surface of the bottom plate through the moving roller, and then the moving wheel is gradually moved out from the inside of the L-shaped limiting plate. Compared with the same type of device in the prior art, the utility model can not only avoid the tipping over of the compact shelving body when moving, but also does not need to install components on the indoor ceiling, thereby reducing installation costs and saving manpower.

[0026] The present disclosure is further described in detail below in conjunction with the accompanying drawings and implementations. It is understood that the specific implementations described herein are only used to explain the relevant content, rather than to limit the present disclosure. It should also be noted that, for ease of description, only the parts related to the present disclosure are shown in the accompanying drawings.
[0027] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in the present disclosure can be combined with each other. The technical solution of the present disclosure will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0028] Unless otherwise specified, the exemplary embodiments / embodiments shown will be understood as providing exemplary features of various details of some ways in which the technical concept of the present disclosure can be implemented in practice. Therefore, unless otherwise specified, the features of the various embodiments / embodiments can be combined, separated, interchanged and / or rearranged without departing from the technical concept of the present disclosure.
[0029] The use of cross-hatching and / or shading in the accompanying drawings is generally used to make the boundaries between adjacent components clear. As such, unless otherwise specified, the presence or absence of cross-hatching or shading does not convey or indicate any preference or requirement for the specific materials, material properties, dimensions, proportions, commonalities between the components shown, and / or any other characteristics, attributes, properties, etc. of the components. In addition, in the accompanying drawings, the sizes and relative sizes of the components may be exaggerated for clarity and / or descriptive purposes. When the exemplary embodiments may be implemented differently, the specific process sequence may be performed in a different order than described. For example, two successively described processes may be performed substantially simultaneously or in an order opposite to the described order. In addition, the same figure numbers represent the same components.
[0030] When a component is referred to as being "on" or "over," "connected to," or "coupled to" another component, the component may be directly on, directly connected to, or directly coupled to the other component, or intervening components may be present. However, when a component is referred to as being "directly on," "directly connected to," or "directly coupled to" another component, there are no intervening components. For this purpose, the term "connected" may refer to a physical connection, an electrical connection, etc., with or without intervening components.
[0031] For descriptive purposes, the present disclosure may use spatially relative terms such as "under," "beneath," "under," "down," "over," "upper," "above," "higher," and "side (e.g., as in "sidewall")," to describe the relationship of one component to another (other) component as shown in the accompanying drawings. The spatially relative terms are intended to encompass different orientations of the device in use, operation, and / or manufacture in addition to the orientation depicted in the accompanying drawings. For example, if the device in the accompanying drawings is turned over, components described as "under" or "beneath" other components or features would subsequently be positioned "over" the other components or features. Thus, the exemplary term "under" can encompass both the "above" and "below" orientations. Furthermore, the device may be otherwise oriented (e.g., rotated 90 degrees or at other orientations), and the spatially relative descriptors used herein should be interpreted accordingly.
[0032] The terms used here are for the purpose of describing specific embodiments, and are not intended to be restrictive. As used here, unless the context clearly indicates otherwise, the singular forms "one (kind, person)" and "said (the)" are also intended to include plural forms. In addition, when the terms "comprise" and / or "include" and their variations are used in this specification, it is explained that there are stated features, integral bodies, steps, operations, parts, assemblies and / or their groups, but it is not excluded that there are or add one or more other features, integral bodies, steps, operations, parts, assemblies and / or their groups. It should also be noted that, as used here, the terms "substantially", "approximately" and other similar terms are used as approximate terms and not as degree terms, so that they are used to explain the inherent deviations of the measured values, calculated values and / or the values provided that will be recognized by those of ordinary skill in the art.
[0033] Figure 1 It is a schematic diagram of the overall structure of a compact shelving base frame according to an embodiment of the present disclosure.
[0034] like Figure 1-Figure 3 As shown, the compact shelving base frame of the present disclosure may include: a connecting frame 1, a moving adjustment mechanism 2, a limiting moving mechanism 3 and other components.
[0035] Figure 2 It is a schematic diagram of the structure of a mobile adjustment mechanism 2 of a compact shelving base frame according to an embodiment of the present disclosure.
[0036] like Figure 2As shown, in a preferred embodiment, the movable adjustment mechanism 2 includes a guide plate 21, a movable plate 22 and a bidirectional screw 23, wherein two guide plates 21 are provided, and the two guide plates 21 are respectively fixedly arranged on both sides of the inside of the connecting frame 1, and two movable plates 22 are provided. Both movable plates 22 are slidably sleeved on the outside of the two guide plates 21 and are located at the two ends of the inner side of the connecting frame 1. The bidirectional screw 23 penetrates the connecting frame 1 and is rotatably connected to the connecting frame 1 through a bearing. The bidirectional screw 23 penetrates the two movable plates 22 and is transmission-connected to the two movable plates 22.
[0037] Therefore, the bidirectional screw 23 is rotated to drive the two moving plates 22 closer to each other. At this time, the moving wheel 32 rolls on the surface of the bottom plate 34 through the moving roller 33, and then the moving wheel 32 gradually moves out from the inside of the L-shaped limiting plate 35.
[0038] Figure 3 It is a schematic diagram of the structure of the limiting movement mechanism 3 of the base frame of a compact shelving system according to an embodiment of the present disclosure.

[0040] Therefore, when the connecting frame 1 is pushed, the movable adjustment mechanism 2 is moved through the four movable wheels 32, and due to the limiting effect of the L-shaped limiting plate 35 on the movable wheel 32, the connecting frame 1 and the movable adjustment mechanism 2 and the dense shelving body on the top of the connecting frame 1 cannot be tilted. In addition, when the limiting movable mechanism 3 is disassembled, the bidirectional screw 23 is rotated so that the bidirectional screw 23 drives the two movable plates 22 to approach each other. At this time, the movable wheel 32 rolls on the surface of the bottom plate 34 through the movable roller 33, and then the movable wheel 32 is gradually moved out from the inside of the L-shaped limiting plate 35.
[0041] In the description of this specification, the description with reference to the terms "one embodiment / method", "some embodiments / methods", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment / method or example are included in at least one embodiment / method or example of the present application. In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment / method or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments / methods or examples in a suitable manner. In addition, those skilled in the art may combine and combine different embodiments / methods or examples described in this specification and the features of different embodiments / methods or examples, unless they are contradictory.
