Description

Technical Field

[0001] The utility model belongs to the technical field of containers, and specifically relates to a container floor plug-in unit and a container floor. Background Art

[0002] The chassis of a refrigerated container is generally composed of an upper T-shaped aluminum floor, a lower corrugated sub-floor, lower side beams on both sides, and a foam layer in the middle. T-shaped aluminum floors are widely used because of their advantages such as less material, high strength, and the ability to provide a channel for cold air. Existing T-shaped aluminum floors are usually divided into sections consisting of multiple T-shaped sections, and then the multiple sections are connected, fixed, and sealed by welding. During the welding process, it is necessary to first spot weld each section to position it, and then weld it in the entire length direction. The operation process is cumbersome and labor-intensive. The aluminum welding process will produce a large amount of welding smoke, harmful gases, etc., which will damage the health of employees. It will also be accompanied by welding defects such as leaking welds and pores, affecting product quality.

[0003] At the same time, with the improvement of people's living standards, the demand for fresh fruits is growing. Refrigeration treatment, as the most suitable anti-corrosion method, is widely used in the transportation of fruits. Refrigerated containers usually use T-shaped aluminum floors as air ducts, and the circulation path for air outlet from the bottom of the refrigeration machine and return air from the top. Over time, structures such as T-shaped aluminum floors are severely corroded, and aluminum rust and rust spots appear on the surface. Usually, in order to eliminate the rust of T-shaped aluminum floors, they will be polished, but this will reduce the structural strength of the T-shaped aluminum floors. Or you can protect the floor by adding a protective layer, but the surface of the T-shaped floor is smooth and the adhesion is not enough. The protective layer will fall off in a short time and lose its function of protecting the T-shaped aluminum floor.

[0004] Therefore, it is a technical problem to be solved urgently to develop a container floor plug-in unit and a container floor, and to achieve sealed connection between T-shaped floors in an environmentally friendly and convenient manner. Utility Model Content

[0060] In some embodiments of the present application, Figure 1 , Figure 5 As shown, the container floor comprises a plurality of container floor plug-in units and a plurality of container floor units. The container floor plug-in unit is used for sealing connection of two adjacent container floor units.

[0061] A plurality of container floor units are arranged in sequence along the length direction of the container floor.

[0062] The container floor unit and the container floor plug-in unit are extended along the width direction of the container floor.

[0063] A container floor plug-in unit is provided. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, it includes a first plug-in portion 100 , a second plug-in portion 200 and a sealing connection portion 300 .

[0064] The first plug-in portion 100 and the second plug-in portion 200 are both extended along the extension direction of the container floor, that is, the first plug-in portion 100 and the second plug-in portion 200 are extended along the width direction of the container floor.

[0065] The sealing connection portion 300 is used for sealing connection between the first plug-in portion 100 and the second plug-in portion 200 .

[0066] An inserting slot 110 is formed on the first inserting portion 100 .

[0067] The second plug-in portion 200 is a plug-in column, and the plug-in column matches with the plug-in slot 110 .

[0068] When the plug-in column is inserted into the plug-in slot 110 , a glue groove is formed between the plug-in column and the plug-in slot 110 .

[0069] The sealing connection part 300 is clamped in the glue-retaining cavity by the plug-in column and the plug-in groove, thereby realizing the sealing connection between the first plug-in part 100 and the second plug-in part 200 .

[0070] In some embodiments of the present application, a plurality of first glue grooves 210 are formed on the plug-in column. The first glue grooves 210 extend along the extension direction of the plug-in column.

[0071] When the plug-in column is inserted into the plug-in slot 110, the first glue groove 210 is connected to the plug-in slot 110. In this state, the first glue groove 210 and the side wall of the plug-in slot 110 are surrounded to form a glue cavity. This glue is defined as the first glue cavity 211. When the sealing connection part 300 is clamped by the first plug-in part 100 and the second plug-in part, the sealing connection part 300 flows between the plurality of first glue cavities and the gap formed between the plug-in slot 110 and the plug-in column, thereby achieving a sealed connection between the first plug-in part 100 and the second plug-in part 200.

[0072] Specifically, the sealing connection portion 300 may be made of sealant.

[0073] In some embodiments of the present application, a first wave portion 111 is formed at a position corresponding to the side wall of the plug slot 110 and the first glue cavity. During the process of inserting the plug column into the plug slot 110 and squeezing the sealing connection portion 300, the first wave portion 111 is used to push the sealing connection portion 300 to fill the first glue cavity and the gap between the plug slot 110 and the plug column. In addition, the first wave portion 111 can increase the contact area between the first plug portion 100 and the sealing connection portion 300, thereby improving the connection stability of the sealed connection.

[0074] Specifically, the first plug-in part 100 is a first plug-in part body formed by bending from the container floor. The first plug-in part body is surrounded by a plug-in slot 110 with an opening facing downward.

[0075] The first end of the first plug-in portion body is connected to the container floor, and the second end of the first plug-in portion body is bent to be close to the container floor.

[0076] The second end of the first plug body is connected with a rubber stop protrusion 120. The rubber stop protrusion 120 abuts against the container floor.

[0077] The rubber stop protrusion 120 is used to prevent the sealing connection part 300 from overflowing to the container floor.

[0078] In some embodiments of the present application, a plurality of second glue grooves 130 are extended and formed on the inner side wall of the plug slot 110. The second glue grooves 130 and the side wall of the plug column are surrounded to form a glue cavity, which is defined as a second glue cavity 131.

[0079] The second glue-retaining cavity 131 is used to accommodate the sealing connection part 300 and is connected between the first plug-in part 100 and the second plug-in part through extrusion and sealing.

[0080] The glue blocking protrusion 120 is connected to a side of the second glue retaining cavity 131 close to the container floor. Since the glue blocking protrusion 120 abuts against the container floor, the sealing connection part 300 is prevented from overflowing to the container floor.

[0081] In some embodiments of the present application, the first end of the first plug-in portion body is connected to the T-shaped rib 410 of the container floor. In this state, the T-shaped rib 410 can provide a side wall of the plug-in slot 110.

[0082] like Figure 2 , Figure 3 , Figure 4 As shown, the first plug-in portion body is L-shaped. The first plug-in portion body includes a first horizontal extension portion 180 and a first vertical extension portion 140 which are sequentially connected end to end.

[0083] The first horizontal extension portion 180 , the first vertical extension portion 140 and the T-shaped rib 410 are arranged to form the insertion groove 110 .

[0084] Specifically, the first glue groove 210 is provided on a side of the plug-in column close to the first vertical extension portion 140 .

[0085] The side of the plug-in column away from the first vertical extension portion 140 abuts against the inner side wall of the plug-in slot 110 , thereby achieving a sealed connection there.

[0086] During the plugging process of the first plug-in portion 100 and the second plug-in portion 200, in order to limit the relative position between the two in the vertical direction, a first limiting protrusion 220 is formed on the side of the plug-in column away from the first vertical extension portion 140. Correspondingly, a first limiting groove 421 is formed at a position corresponding to the floor horizontal extension portion 420 of the container floor.

[0087] During the plugging process between the first plugging part 100 and the second plugging part 200 , the first limiting protrusion 220 and the first limiting groove 421 are moved to stop against each other, thereby realizing the relative position of the first plugging part 100 and the second plugging part 200 in the vertical direction.

[0088] In some embodiments of the present application, Figure 6 , Figure 7 , Figure 8 As shown, the first end of the first plug-in portion body is connected to the floor horizontal extension portion 420 of the container floor, and the first plug-in portion body can adopt an inverted U-shaped or inverted V-shaped structure.

[0089] The first plug-in portion body includes a second vertical extension portion 150 , a second horizontal extension portion 160 , and a third vertical extension portion 170 which are sequentially connected end to end.

[0090] The second vertical extension portion 150 , the second horizontal extension portion 160 and the third vertical extension portion 170 are connected end to end in sequence.

[0091] The second vertical extension portion 150 is connected to the floor horizontal extension portion 420 .

[0092] The glue blocking protrusion 120 is connected to the lower end of the third vertical extension portion 170 .

[0093] A plurality of first glue grooves 210 are dispersedly disposed on two side walls of the plug-in column close to the second vertical extension portion 150 and the third vertical extension portion 170. The first glue grooves 210 are extended along two side walls of the plug-in column.

[0094] A second position limiting groove 422 is formed at the connection between the second vertical extension portion 150 and the floor horizontal extension portion 420. A second position limiting protrusion 230 is formed on one side of the plug-in column close to the second vertical extension portion 150.

[0095] During the plugging process between the first plugging part 100 and the second plugging part 200 , the second limiting protrusion 230 and the second limiting groove 422 are moved to stop against each other, thereby realizing the relative position of the first plugging part 100 and the second plugging part 200 in the vertical direction.

[0096] In some embodiments of the present application, during the assembly process of the container floor, two adjacent container floor units are connected via a container floor plug-in unit.

[0097] Specifically, the first plug-in portion 100 and the second plug-in portion 200 are respectively connected to two adjacent container floor units. When the first plug-in portion 100 and the second plug-in portion 200 are in the plugged state, the sealing connection portion 300 is sealed between the two, thereby achieving a sealed connection between adjacent container floor units.

[0098] The container floor unit includes a plurality of T-shaped ribs 410 and a plurality of floor horizontal extensions 420. The plurality of T-shaped ribs 410 and the plurality of floor horizontal extensions 420 are connected at intervals to form the container floor unit.

[0099] Since the T-shaped vertical rib 410 is the main stress-bearing part of the container floor unit, the first plug-in part 100 and the second plug-in part 200 are both connected to the horizontal extension part 420 of the floor, which can reduce the stress at the connection between the first plug-in part 100 and the second plug-in part 200 and ensure the service life of the first plug-in part 100 and the second plug-in part 200.

[0100] In some embodiments of the present application, Fig. 9 As shown, in order to increase the connection stability between the protective layer and the container floor and prevent the protective layer from falling off, a second wave portion 430 is formed along the surface of the T-shaped vertical rib 410 and the upper surface of the horizontal extension portion 420 of the floor.

[0101] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0102] The above is only a specific implementation method of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
