Description

Technical Field

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

[0002] Currently, there are two main types of sill sealing connection structures for refrigerated and / or frozen containers: one is a concealed bolt connection structure, and the other is an embedded connection structure.

[0003] The drawback of the concealed bolt connection structure is that after long-term use, moisture will seep into the interior of the bubble through the bolt connection, which will reduce the strength of the entire threshold area and shorten the life of the container. At the same time, the bolt connection forms a thermal bridge, increasing heat leakage in the area, which is not conducive to the preservation of goods inside the frozen and / or refrigerated container. In addition, this structure is complicated to assemble, which restricts the efficiency of the production line.

[0004] The drawback of the inlaid connection structure is that, due to the limitations of the connector's structure, the sealant is usually exposed. During container use, transportation, and cleaning, the exposed sealant is prone to detachment, affecting the overall sealing of the sill area. Furthermore, because of the significant difference in strength between the metal and plastic components at the sill, the inlaid structure tends to separate over time, creating gaps at the joint. Moisture can then enter the sill area through these gaps, damaging the structure and affecting the container's lifespan.

[0005] Therefore, a threshold structure and a container are needed to at least partially solve the above problems. Utility Model Content

[0025] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings.

[0026] refer to Figure 1 This application provides a sill structure 100 that can be applied to the rear sill of a container. The sill structure 100 includes a metal connecting beam 110, an inner beam 120, an outer beam 130, a first non-metallic support member 140, and a second non-metallic support member 150. The metal connecting beam 110 is used for fixed connection to the container floor 10, preferably by welding. The inner beam 120 is spaced below the metal connecting beam 110. The outer beam 130 is located on the side of the metal connecting beam 110 away from the floor 10, and the upper end of the outer beam 130 is higher than the inner beam 120. The upper end of the outer beam 130 forms a bent portion 131 extending toward the metal connecting beam 110, and there is a gap between the bent portion 131 and the metal connecting beam 110. The first non-metallic support member 140 is disposed on the inner beam 120, and a limiting groove 141 is formed on the upper surface of the first non-metallic support member 140. The second non-metallic support member 150 includes a body portion 151 and a filling portion 154. The main body 151 is disposed in the limiting groove 141 of the first non-metallic support 140, and the main body 151 is at least partially pressed under the metal connecting beam 110 and the bending portion 131. The filling portion 154 protrudes from the main body 151, fills the gap between the metal connecting beam 110 and the bending portion 131, and the filling portion 154 is sealed to the metal connecting beam 110 and the bending portion 131.

[0027] The threshold structure 100 of this application ensures both strength and sealing, and is easy to assemble, thus improving production efficiency.

[0028] The sill structure 100 also includes a third non-metallic support 170, which connects the metal connecting beam 110 and the inner beam 120. Optionally, the first non-metallic support 140 is connected to the outer beam 130 by rivets 171. The first non-metallic support 140 can be made of PE, PVC, foamed PVC, elastomer, or rubber, etc.; the second non-metallic support 150 can be made of PE, PVC, or other similar materials; and the third non-metallic support 170 can be made of PE, PVC, foamed PVC, elastomer, or rubber, etc. The connecting beam can be made of aluminum, specifically aluminum profiles.

[0029] Specifically, a sealing element 160 is provided between the filling portion 154 and the metal connecting beam 110, and between the filling portion 154 and the bending portion 131, thereby achieving excellent sealing performance. As an optional embodiment, a recessed groove is provided at the junction of the filling portion 154 and the body portion 151, and the sealing element 160 is located in the recessed groove, thereby concealing the sealing element 160 so that it is not visible on the surface and preventing damage to the sealing element 160. As an example, the upper surface of the end of the metal connecting beam 110 near the outer beam 130, the upper surface of the filling portion 154, and the upper surface of the bending portion 131 form a flat surface.

[0030] Furthermore, the metal connecting beam 110 and the second non-metallic support member 150 are connected by a snap-fit ​​mechanism. More specifically, the end of the metal connecting beam 110 near the outer beam 130 is provided with a tenon structure, and the body part 151 is provided with a mating structure, with the tenon structure and the mating structure forming a snap-fit ​​connection.

[0031] Here, we first define the forward direction D1 and the backward direction D2. The forward direction D1 is the direction closer to the outer beam 130. Correspondingly, the backward direction D2 is the direction away from the outer beam 130, opposite to the forward direction D1. In other words, the combination of the forward direction D1 and the backward direction D2 represents the container's longitudinal direction, or its length direction.

[0032] The latching structure includes a first latch 111, which is disposed on the bottom surface of the metal connecting beam 110 and protrudes downward. The hook head of the first latch 111 extends in the forward direction D1. A latching groove 152 is provided on the body 151, and the bottom of the latching groove 152 extends in the forward direction D1 so that the side of the first latch 111 facing the forward direction D1 can fit into the latching groove 152. For example, the first latch 111 can be constructed as an L-shape, and the latching groove 152 can be constructed as an L-shaped groove accordingly. The depth of the latching groove 152 is adapted to the height of the first latch 111, and the maximum dimension of the latching groove 152 in the forward direction D1 is greater than the maximum dimension of the first latch 111 in the forward direction D1, so that the first latch 111 can have room to move in the latching groove 152, which facilitates the operation during assembly.

[0033] In a preferred embodiment, the latch structure further includes a second latch 112, which is disposed on the bottom surface of the metal connecting beam 110 and protrudes downward, with the hook head extending in the forward direction D1. In other words, the second latch 112 can be constructed with a shape similar to the first latch 111. The second latch 112 is spaced apart from the rear side of the first latch 111. Correspondingly, the surface of the body portion 151 facing away from the forward direction D1 has a recessed structure 153, and the second latch 112 engages with the recessed structure 153. Thus, during assembly, the first latch 111 is first placed into the latch groove 152, and after the first latch 111 is moved into place and engaged with the latch groove 152, the second latch 112 also engages precisely with the recessed structure 153.

[0034] A second aspect of this application provides a container, the container including the threshold structure 100 of the first aspect described above.

[0035] The container according to this utility model has similar technical effects to the threshold structure 100 of the first aspect described above.

[0036] Unless otherwise defined, the technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used herein is for descriptive purposes only and is not intended to limit the scope of the invention. Features described in one embodiment may be applied, alone or in combination with other features, to another embodiment, unless that feature is not applicable in that other embodiment or is otherwise stated.

[0037] This utility model has been described through the above embodiments. However, it should be understood that the above embodiments are only for illustrative purposes.
