[0001] This utility model relates to the field of vehicle floor technology, and in particular to a retractable movable vehicle floor. Background Technology

[0002] The car floor usually refers to the plate structure that makes up the bottom of a railway freight car or passenger car, and it is an important load-bearing component of the vehicle.

[0003] However, it still has the following drawbacks in practical use:

[0004] To meet usage requirements, the existing carriage floor uses a sliding connection structure that allows for retraction and extension. However, the sliding connection only allows for retraction and extension to both sides, limiting its functionality and applicability, and thus failing to meet usage needs. Utility Model Content

[0005] The purpose of this utility model is to provide a retractable movable carriage floor to solve the problem mentioned in the background art, where the existing carriage floor adopts a sliding connection method to meet the needs of use, and can be extended and retracted. However, the sliding connection of the floor can only extend and retract to both sides, which limits its function and applicability, and cannot meet the needs of use.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a retractable movable carriage floor, comprising:

[0008] The carriage itself;

[0009] The telescopic base plate includes a guide rail, a guide block, a bracket, a left telescopic plate, and a right telescopic plate.

[0010] The guide rail is symmetrically threaded at the lower end of the carriage body, and the guide block is symmetrically slidable in the middle of the lower end of the guide rail. The bracket is threaded in the middle of the lower end of the guide block, and the left telescopic plate is fixed to the lower end of one set of the brackets on one side, and the right telescopic plate is fixed to the lower end of another set of the brackets on the other side.

[0011] Furthermore, the guide block is U-shaped, and a threaded post is threaded through the upper end of the bracket, with the end of the threaded post extending out of the lower end of the guide block.

[0012] Furthermore, a magnetic block is embedded on the inner side of the guide block.

[0013] Furthermore, it also includes a locking mounting part, which includes a locking bolt, a rotating sleeve, a movable tube, a movable spring, and a movable column;

[0014] The locking bolt is threaded through the end of the guide rail, and the rotating sleeve is fitted onto the lower part of the locking bolt. The movable tube is fixed in the middle of the inner side of the rotating sleeve, and one end of the movable spring is fixed inside the movable tube. The movable column is fixed to the other end of the movable spring.

[0015] Furthermore, the lower part of the locking bolt is provided with a hexagonal protrusion, and the rotating sleeve is sleeved with the hexagonal protrusion.

[0016] Furthermore, the rotating sleeve has a hexagonal cavity in the middle, and a cap is snapped onto the upper end of the hexagonal cavity.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] This utility model includes a guide rail, a guide block, and a bracket. The left and right telescopic plates are threaded onto the lower end of the bracket. By applying an outward pulling force to the left and right telescopic plates, and through the sliding of the guide block within the guide rail, they can extend and retract horizontally outward. After extending and retracting outward, an inward force can be applied to the left and right telescopic plates to rotate them to a vertical angle, thus satisfying the needs of adjusting the height of the carriage body and storing goods. The structure is highly adaptable and can be used in various functional ways.

[0019] Based on the above-mentioned beneficial effects, the device is equipped with a movable column, a movable spring, and a rotating sleeve.

[0028] 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.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0030] Please see Figure 1-4 As shown, this embodiment is a retractable movable carriage floor, comprising:

[0031] Carriage body 1;

[0032] The carriage body 1 serves as the main installation carrier;

[0033] The telescopic base plate includes a guide rail 21, a guide block 22, a bracket 23, a left telescopic plate 24, and a right telescopic plate 25.

[0034] The guide rail 21 is symmetrically threaded at the lower end of the carriage body 1, and the guide block 22 is symmetrically slidable in the middle of the lower end of the guide rail 21. The bracket 23 is threaded in the middle of the lower end of the guide block 22, and the left telescopic plate 24 is fixed to the lower end of a set of brackets 23 on one side, and the right telescopic plate 25 is fixed to the lower end of a set of brackets 23 on the other side.

[0035] The guide rail 21 provides structural installation for the guide block 22. By sliding the guide block 22 within the guide rail 21, the left telescopic plate 24 and the right telescopic plate 25 can be extended and retracted outwards. The guide block 22 also provides structural installation for the bracket 23. The bracket 23 provides structural installation for the left telescopic plate 24 and the right telescopic plate 25. The left telescopic plate 24 and the right telescopic plate 25 can meet the requirements for inward and outward extension and storage.

[0036] The guide block 22 is U-shaped, and the upper end of the bracket 23 is threaded through the threaded post 26, and the end of the threaded post 26 extends out of the lower end of the guide block 22.

[0037] The U-shaped design facilitates the rotation of the bracket 23, while the threaded column 26 is used to install both the bracket 23 and the guide block 22, and the angle of the left telescopic plate 24 and the right telescopic plate 25 can be adjusted by rotating the thread.

[0038] A magnetic block is embedded on the inner side of the guide block 22;

[0039] The mutual magnetic attraction between the magnetic blocks defines the structure of a group of conductive blocks 22 that are in contact and attached.

[0040] Working principle: When the carriage floor is used internally, an inward force is applied to the left telescopic plate 24 and the right telescopic plate 25 until the guide block 22 is magnetically attached, thereby strengthening the structure of the lower part of the carriage floor.

[0041] When using the car floor externally, the above reverse steps are applied so that the left telescopic plate 24 and the right telescopic plate 25 extend out, and the car floor is used for horizontal extension.

[0042] When adjusting the height of the carriage body 1, apply an inward force to the extended left telescopic plate 24 and right telescopic plate 25, and rotate the screw to make the left telescopic plate 24 and right telescopic plate 25 perpendicular to the horizontal plane.

[0043] This solution has strong structural adaptability and can be used in various functional ways to meet different usage needs.

[0044] Please see Figure 1-4 As shown, this embodiment is based on the above embodiment 1, and further includes a locking mounting part, which includes a locking bolt 31, a rotating sleeve 32, a movable tube 33, a movable spring 34, and a movable column 35;

[0045] The locking bolt 31 is threaded through the end of the guide rail 21, and the rotating sleeve 32 is sleeved on the lower part of the locking bolt 31. The movable tube 33 is fixed in the middle of the inner side of the rotating sleeve 32, and one end of the movable spring 34 is fixed inside the movable tube 33. The movable column 35 is fixed to the other end of the movable spring 34.

[0046] The locking bolt 31 is used to install and fix the guide rail 21. The rotating sleeve 32 applies the force required for disassembling and assembling the locking bolt 31, and installs the cover 36 and the movable tube 33. The movable spring 34 is installed through the movable tube 33 and provides expansion and contraction space. The movable spring 34 is installed on the movable column 35. Through its own expansion and contraction, it can protect the guide block 22 from collision.

[0047] The locking bolt 31 has a hexagonal protrusion at the bottom, and the rotating sleeve 32 is sleeved with the hexagonal protrusion;

[0048] The hexagonal protrusion, in conjunction with the rotating sleeve 32, allows the force required to rotate the locking bolt 31 to be applied.

[0049] The rotating sleeve 32 has a hexagonal cavity in the middle, and a cap 36 is snapped onto the upper end of the hexagonal cavity;

[0050] The hexagonal cavity satisfies the connection between the hexagonal protrusion and the cover 36 seals the upper part of the rotating sleeve 32, and can provide external protection for the locking bolt 31 after locking.

[0051] Working principle: The rotating sleeve 32 is pre-fitted onto the lower part of the locking bolt 31, and a rotating tightening force is applied to tighten the locking bolt 31 for the installation of the guide rail 21 structure. After installation, the cover 36 is snapped onto the lower end of the rotating sleeve 32.

[0052] At this time, during the sliding of the guide block 22, the front end of the movable column 35 contacts the sliding guide block 22, and the movable spring 34, after being subjected to force, is compressed and moves into the movable tube 33. After restoring its deformation, it applies a reverse force to the movable column 35, which can buffer the guide block 22.

[0053] This solution, while satisfying the disassembly and assembly of the locking bolt 31 and providing external protection, can also provide anti-collision protection for the guide block 22, saving costs and making it convenient to use.

[0054] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
