Description

Technical Field

[0001] This utility model relates to the field of container manufacturing technology, and more specifically, to a threshold structure. Background Technology

[0002] As a key structure at the bottom of the container, the sill of the container plays a crucial role in providing closed support, transmitting force, waterproofing and sealing, raising the standard for loading and unloading operations, and enhancing the overall structural rigidity.

[0003] The existing container thresholds, due to their frequent use in loading and unloading cargo, must be strengthened overall, such as... Figure 2 As shown, a PE block is usually set on the main body, such as Figure 3 As shown, four C-shaped angle steel sections are welded to the threshold at the same time, with two pairs of steel sections arranged opposite each other. A PE block is embedded in each set of angle steel sections, and the PE block is fixed by the groove of the C-shaped angle steel section. However, this design makes the production process complicated.

[0004] Therefore, it is necessary to optimize the existing structure while ensuring the overall structural strength of the threshold, and solve the problem of cumbersome threshold manufacturing process in the existing technology. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a threshold structure to solve one or more of the above-mentioned problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A threshold structure includes an aluminum threshold, on which a PE block is embedded. An extension section is provided at the bottom of the aluminum threshold, and a fixing groove is provided on the PE block. The PE block is fixed by the extension section and the fixing groove.

[0008] Furthermore, the PE block has a fixing groove on its inner and outer sides, and a number of the extension segments are provided corresponding to the fixing grooves, with the ends of the extension segments having opposing fold-back sections.

[0009] Furthermore, the fixing grooves on the inner and outer sides of the PE block are staggered, and the extension sections are set at different heights.

[0010] Furthermore, several of the extended sections form a receiving cavity, and the upper end of the PE block is fixed inside the receiving cavity.

[0011] Furthermore, a gap is left between the inner wall of the accommodating cavity and the side of the PE block, and a gap is left between the fixing groove and the folded section at the end of the extension section.

[0012] Furthermore, the bottom of the PE block abuts against the bottom plate of the box.

[0013] In summary, this utility model has the following beneficial effects: by adding an integrated extension section to the aluminum threshold and opening a fixing groove on the PE block, the structure of the C-shaped angle steel is eliminated, the welding process is simplified, the threshold strength is improved, and the overall foaming quality is improved.

[0018] Example:

[0019] The following is in conjunction with the appendix Figure 1 The present invention will be described in further detail below.

[0020] A threshold structure, such as Figure 1 As shown, the entire assembly is installed on the opening side of the container body, relying on the container body. An aluminum sill 1 is provided on the opening side, with a certain space between the aluminum sill 1 and the container bottom plate. A PE block 2 is embedded within this space, with its top abutting against the aluminum sill 1 and its bottom contacting the container bottom plate. Each side of the PE block 2 has a separate fixing groove 4. Preferably, the inner and outer fixing grooves 4 are at different heights, creating a staggered arrangement, and the number of fixing grooves 4 on each side can be different. An integral extension section 3 is provided at the bottom of the corresponding position of the aluminum sill 1. The number of extension sections 3 on the aluminum sill 1 is the same as the number of fixing grooves 4 on the PE block 2. Correspondingly, the length of the downward-hanging extension section 3 should be set according to the expected position of the fixing groove 4 after the PE block 2 is inserted, and can vary in length. The tail of the extension section 3 has a folded-back section, forming an L-shaped cross-sectional structure. Opposite extension sections 3 with folded-back sections face each other, forming a closed-off accommodating cavity 5. The upper end of the PE block 2 is fixed within the accommodating cavity 5. The number of accommodating cavities 5 is determined according to the required length. The PE block 2 is fixed by its own fixing groove 4 and the downward extension section 3 of the aluminum threshold 1. A gap is left between the inner wall of the accommodating cavity 5 and the side of the PE block 2, and a gap is left between the fixing groove 4 and the folded section at the end of the extension section 3. This is to allow for structural slack and facilitate adjustment, and to avoid direct contact, friction and compression that could lead to bending and deformation.

[0021] Compared with the existing technology, the extension section 3 under the aluminum threshold 1 and the fixing groove 4 on the PE block 2 are added, the C-shaped angle steel on the surface of the aluminum threshold 1 is eliminated, the processing and welding difficulty is significantly reduced, and the PE block 2 is changed from the original bottom fixing method to the current top fixing method, which has a better support effect and is more suitable for practical use. The overall strength of the threshold is strengthened, and the overall foaming quality is significantly improved.

[0022] It should be noted that this specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
