[0026] Below, in conjunction with the accompanying drawings and specific embodiments, the present invention is further described:

[0027] like Figure 1 , 2, 3, and 4 show a container chassis of the present invention, which includes a plurality of bottom cross beams 10, a floor 20, and two supporting seats 30 arranged opposite to each other. The bottom cross beams 10 extend along the width direction of the container chassis (i.e., the Y direction in the figure), and the plurality of bottom cross beams 10 are arranged along the length direction of the container chassis (i.e., the X direction in the figure), and an installation gap 11 is formed between two adjacent bottom cross beams 10. The floor 20 is laid on the plurality of bottom cross beams 10, and the floor 20 and the plurality of bottom cross beams 10 constitute the main body of the container chassis; two through grooves 23 are provided on the floor 20, and the length direction of the two through grooves 23 is consistent with the X direction, and, The two through grooves 23 are symmetrically distributed on both sides of the longitudinal center line of the floor 20, that is, the two through grooves 23 are arranged opposite to each other, and a support beam 22 is arranged on the inner side of the through groove 23 on the floor 20, and a support beam 21 is arranged on the outer side of the through groove 23 on the floor 20. The support beam 22 and the support beam 21 are both extended along the X direction and fixed on the top surface of the bottom cross beam 10. The support beam 22 and the support beam 21 are respectively provided with flanges facing the middle of the width direction of the through groove 23, and the flanges of the two respectively form a supporting edge, that is, a supporting edge is respectively arranged on both sides of the through groove 23 on the floor 20, wherein the support on the support beam 22 The edge is the inner supporting edge 221, and the supporting edge on the supporting beam 21 is the outer supporting edge 211; a supporting member 40 is arranged in the installation gap 11, and a first supporting portion and a second supporting portion are arranged on the supporting member 40, and the supporting member 40 can be directly or indirectly fixed on the floor 20 or the bottom cross beam 10; the above-mentioned two supporting seats 30 correspond to the two through grooves 23 respectively, and the two supporting seats 30 are arranged oppositely, and the supporting seat 30 includes a supporting plate 31, a support 33 and a mounting seat 32, wherein the support 33 and the mounting seat 32 are both fixed on the lower surface of the supporting plate 31, and the support 33 and the mounting seat 32 can be set in two or more, wherein the support 33 may be composed of more than two square tubes, the top ends of the two or more square tubes are welded and fixed to the lower surface of the support plate 31 and are located at different positions in the width direction of the support plate 31, and the bottom ends of the square tubes are welded and fixed together to form a support end 331 at the bottom end of the support 33, and the support end 331 can cooperate with the outer support edge 211; a support unit is provided on the mounting seat 32, and the support unit can be a pin 321, and the pin 321 can be clamped on the first support part of the support member 40, or can be clamped on the second support part of the support member 40, wherein the height position of the second support part is higher than the height position of the first support part;The pin shaft 321 serves as a supporting unit, which can swing between a first position placed on the first supporting portion and a second position placed on the second supporting portion, so that the support seat 30 forms two placement states on the container chassis. When the above-mentioned pin shaft 321 is in the first position placed on the first supporting portion, the support plate 31 is accommodated in the through groove 23, and the outer side edge 311 of the support plate 31 overlaps the outer supporting edge 211, and the inner side edge 312 of the support plate 31 overlaps the inner supporting edge 221. The support seat 33 and the mounting seat 32 located below the support plate 31 are accommodated in the installation gap 11. Two or more supports 33 and mounting seats 32 can be placed in different installation gaps 11 respectively, or they can be accommodated in the installation gaps 11 opposite to them according to actual sizes. Since the second supporting portion is higher than the first supporting portion, , so that when the pin shaft 321 swings from the first support part to the second support part, the position of the pin shaft 321 is raised. In this way, when the pin shaft 321 is in the second position placed on the second support part, the outer side 311 of the support plate 31 is raised to a position higher than the floor 20. At the same time, the support end 331 at the bottom end of the support 33 is overlapped on the outer support edge 211. At this time, the support seat 30 is supported by two parts on the container chassis (the outer support edge 211 and the second support part on the support member 40), so that when the support seat 30 is not subjected to other external forces in this state, its position and angle can remain fixed. In this way, the support plates 31 on the support seat 30 are inclined, and the support plates 31 on the two support seats 30 together form a V-shaped support structure to meet the placement requirements of cylindrical goods. ;

[0028] When the pin 321 is in the Figure 7 In the first position shown in FIG. 1 , the two sides of the support plate 31 are respectively overlapped on the inner support edge 221 and the outer support edge 211. At this time, when the container chassis carries goods, the pressure on the support plate 31 is transmitted downward to the bottom cross beam 10 through the support beams 22 and 21. In other embodiments, the support beams 22 and 21 may not be provided. Figure 7 In the state shown, the top surface of the bottom cross beam 10 can be directly used to abut against the support plate 31 .

[0029] In a preferred embodiment, the present invention provides a guide groove 41 on the support member 40, and the above-mentioned pin shaft 321 is inserted into the guide groove 41. After the pin shaft 321 is embedded in the guide groove 41, it can slide along the extension direction of the guide groove 41. The first support part and the second support part are respectively arranged at the two ends of the guide groove 41. Specifically, the first support part is a card slot 414 provided on the support member 40, and the second support part is a card slot 413 provided on the support member 40. The card slot 414 and the card slot 413 can respectively cooperate with the pin shaft 321. When the pin shaft 321 is in the first position, the pin shaft 321 is clamped in the card slot 414. When the pin shaft 321 is in the second position, the pin shaft 321 is clamped in the card slot 413. The guide groove 41 may be configured as two sections, specifically including a first section 412 and a second section 411, wherein the first section 412 extends upward from the card slot 414, and the second section 411 extends obliquely downward from the top end of the first section 412 to the card slot 413, wherein the height of the card slot 413 is higher than the height of the card slot 414, and when the pin shaft 321 slides from the card slot 414 to the card slot 413 along the guide groove 41, the support plate 31 on the support seat 30 is flipped from the state of being completely accommodated in the through groove 23 to the state of being as shown in FIG. Figure 3 , 4 The V-shaped support structure is shown; Figure 4 , 5 , 6, and 7 sequentially illustrate the state in which the support plate 31 is turned over from a state of forming a V-shaped support structure to a state in which it is completely accommodated in the through groove 23, wherein Figure 4 In the state shown, the support plate 31 is flipped to an inclined state higher than the upper surface of the floor 20. At this time, the pin shaft 321 is placed in the slot 413, and the support end 331 on the support 33 is supported by the outer support edge 211. Since the second section 411 of the guide groove 41 is inclined and the slot 413 is located at a relatively low end of the second section 411, the inclination angle of the second section 411 is used to prevent the pin shaft 321 from sliding along the second section 411, and the support end 311 and the outer support edge 211 support each other to prevent the pin shaft 321 from being displaced, thereby achieving self-locking of the pin shaft 321; Figure 5 As shown, when the state of the support seat 30 needs to be changed, the support seat 30 is lifted upward by a small displacement, and the support seat 30 is rotated toward the inner side of the container chassis by a small angle around the pin shaft 321, and the pin shaft 321 has the freedom to move upward along the second section 411. At this time, the support seat 30 is continuously lifted upward, so that the pin shaft 321 can be disengaged from the slot 413 and slide along the second section 411. Figure 5 FIG. 4 illustrates the state where the support base 30 is subjected to an external force and the pin 321 slides to the top of the second section 411 (i.e., the position connected to the first section 412); see FIG. Figure 6As shown, when the pin 321 slides over the top of the second section 411, the pin 321 slides into the first section 412. At this time, the external force on the support seat 30 is released, and the pin 321 can slide downward along the first section 412, that is, the support seat 30 slides downward in the installation gap 11. Finally, as shown in FIG. Figure 7 As shown, the pin 321 slides into the slot 414, the support seat 30 lowers in height in the installation gap 11 and flips at an angle, the support seat 30 is completely in the installation gap 11, the support plate 31 is completely received in the through slot 23, the outer side edge 311 of the support plate 31 overlaps the outer support edge 211, and the inner side edge 312 overlaps the inner support edge 221. The angle between the second section 411 of the guide groove 41 and the floor 20 is a, that is, the angle between the second section 411 of the guide groove 41 and the horizontal plane is a, preferably 45°≥a≥5°. In actual use, the angle a is set to 23°, so that the pin 321 can achieve self-locking while the support seat 30 is moving from Figure 4 The state shown is raised to Figure 5 When the display is in the state shown, it can save time and effort.

[0030] The pin shaft 321 of the present invention is used as a supporting unit, which is inserted into the guide groove 41, so as to prevent the support seat 30 from being completely separated from the container chassis, and at the same time ensure that the support seat 30 is in a state of being relatively close to the container chassis. Figure 4 The open state shown and Figure 7 The snap-fitting state shown. In order to match the installation of the pin 321, the mounting seat 32 may include two support plates, the top end of the support plate is fixed to the lower surface of the support plate 31, and the pin 321 is fixed between the bottom ends of the two support plates. Specifically, the pin 321 may be a bolt that crosses the two support plates, and is locked on the support plates with a nut. During installation, the two support plates are placed on both sides of the support member 40, and the pin 321 passes through the two support plates and the guide groove 41 in turn, and then is locked with a nut. It should be emphasized that in other embodiments, two card slots may be directly opened on the support member 40, and the two card slots are recessed positions set at the edge of the support member 40. As long as they can cooperate with the pin 321 to position the pin 321, there is no need to consider whether the support seat 30 is separated from the container chassis. It can be used in the following embodiments. Figure 4 , 7 The states shown can respectively play a supporting role for the pin shaft 321 .

[0031] In the above structure of the present invention, a support beam 21 and a support beam 22 are respectively arranged on both sides of the through groove 23 on the floor 20. In fact, a support beam 22 can be arranged at a position between the two through grooves 23, that is, the support plate 31 on the support seat 30 shares the support beam 22. The cross-sectional shape of the support beam 22 is Ω, and the flanged parts extending on both sides thereof form two inner support edges 221, thereby respectively providing the inner side edges 312 of the two support plates 31 for overlapping. In order to ensure that the upper surface of the container chassis has a better flatness, the above-mentioned support beam 21 and support beam 22 are fixed above the top surface of the bottom cross beam 10, and the upper surfaces of the two are flush with the upper surface of the floor 20; at the same time, the thickness of the support plate 31 is the same as the thickness of the floor 20. Figure 7 In the state shown, when the pin 321 is locked in the slot 414, the support seat 30 is in a buckled state, and the upper surface of the support plate 31 is flush with the upper surface of the floor 20, so that the upper surface of the container chassis is flat as a whole, so that the container chassis can be suitable for the transportation of other types of goods. The support beams 21 and 22 are provided to provide support for the support seat 30. The support beams 21 and 22 are fixed on the bottom cross beam 10, which extend along the longitudinal direction of the container chassis, and can also increase the strength of the container chassis. The structure of the support beams 21 and 22 is suitable for the container chassis whose floor 20 is a wooden floor or a bamboo-wood composite floor. When the floor 20 is a steel floor or other materials with better strength, the above-mentioned support beams 21 and 22 can also be omitted, and the floor 20 is directly bent downward at the two sides of the through groove 23 and turned to form the inner support edge 221 and the outer support edge 211.

[0032] A downwardly extending fixed vertical plate 212 is provided on the support beam 21, and the fixed vertical plate 212 extends downward from the side of the support beam 21 close to the through groove 23 to the installation gap 11. The two ends of the fixed vertical plate 212 are respectively fixedly connected to the bottom cross beam 10 located on both sides of the installation gap 11, and a sealing plate 12 covering the installation gap 11 is fixed at the bottom of the bottom cross beam 10 and the fixed vertical plate 212. The sealing plate 12 seals the frame composed of the fixed vertical plate 212 and the bottom cross beam 10 in a closed state, that is, the position of the through groove 23 at the bottom of the container chassis is sealed by the sealing plate 12, and one end of the above-mentioned support member 40 is welded and fixed to the sealing plate 12, and the other end is welded and fixed to the fixed vertical plate 212. In other embodiments, the support member 40 may be fixed on the floor 20, or may be directly fixed on the bottom beam 10, or the portion of one of the bottom beams 10 located below the through groove 23 may be regarded as a support member, and the above-mentioned guide groove may be opened on the bottom beam 10 so that the pin shaft 321 may cross the guide groove provided on the bottom beam 10.

[0033] It should be pointed out that the pin 321 as the support unit can also be replaced by other components. In the case of providing the guide groove 41, the support unit only needs to be able to slide along the guide groove 41 and be able to be clamped in the clamping groove 413 and the clamping groove 414. Of course, in the embodiment where the guide groove is not provided, if the support member is a plate-shaped structure, the top edge of which is a bevel, a clamping groove is provided in the higher part of the bevel and a clamping groove is provided in the lower part, the support unit is embedded in the lower clamping groove when the support plate 31 is in the buckled position, and is embedded in the higher clamping groove when the support plate 31 is turned up.

[0034] For ease of operation, a downwardly recessed recess 313 is provided on the upper surface of the support plate 31, and a handle 34 is provided in the recess 313. The handle 34 is hinged to the support plate 31. When the support base 30 needs to be flipped, the support base 30 can be pulled up using the handle 34. In the non-operating state, the handle 34 can be accommodated in the recess 313 and will not protrude from the upper surface of the support plate 31.

[0035] It should be emphasized here that the container chassis of the present invention can be provided with two through grooves 23 and two support seats 30, and the two support seats 30 form a group to form a V-shaped support structure for preventing cylindrical goods. In fact, multiple groups of support seats 30 can also be provided along the length direction of the container chassis, and multiple groups of through grooves 23 can be correspondingly provided on the floor 20. In the above scheme, the two support seats 30 are symmetrically distributed on both sides of the longitudinal center line of the container chassis. For some special box types, the symmetry axes of the two support seats 30 do not necessarily coincide with the longitudinal center line of the container chassis. For example, when transporting some steel coils with smaller diameters, two steel coils are arranged in the width direction of the container, and correspondingly, two groups of support seats 30 are arranged in the width direction of the container; Figure 1 The container chassis shown is suitable for containers with doors at the ends. When the two support seats 30 are turned up, the extension direction of the V-shaped support structure formed is consistent with the length direction of the container chassis, and the steel coil is placed on the V-shaped support structure from the end of the container using a forklift. When the container chassis of the present invention is applied to side-opening containers or side curtain containers, the support seats 30 can be extended along the width direction of the container chassis, that is, the symmetry axes of the two support seats 30 are consistent with the width direction of the container chassis. In this way, when the support seats 30 are turned up, the extension direction of the V-shaped support structure formed is consistent with the width direction of the container chassis, so that the steel coil is placed on the V-shaped support structure from the side of the container.

[0036] The container of the present invention includes the above-mentioned container chassis, two side frames respectively located on both sides of the container chassis, two end walls respectively located at both ends of the container chassis, a box door installed on one of the end walls, and a top cover sealed on the top of the two side frames and the two end walls. The top cover can be welded and fixed to the side frames and the end walls, or can be fixed to the top of the side frames and the end walls in a detachable manner. When transporting large-diameter cylindrical materials such as steel coils, the support plate is flipped to form a V-shaped support structure. When used as a common container, the support seat is flipped so that the support plate is accommodated in the through groove. Compared with the prior art, the present invention can be suitable for the transportation of large-diameter cylindrical goods, and can also be used as an ordinary bulk container, which increases the scope of application of the container, avoids the situation where the container is returned empty, and greatly saves transportation costs.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents, and these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
